Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is capable of efficiently and safely carrying out the work such as transportation, installation, and removal of a considerably heavy article for a small piece such as a lid covering a concrete road gutter with the least effort. The present invention relates to a small heavy object transportation / installation device.

[0002]

[Prior art]

 The installation work of the above-mentioned gutter lid had to rely on human power once. The work of fitting the heavy gutter cover onto the gutter was a heavy labor, and there was always the risk of getting hands or feet caught in the gutter cover. However, these days, using self-propelled machinery such as cranes and backhoes, the above work can be performed without any effort. However, in addition to the cost of purchasing, maintaining or borrowing these machines, these machines also require two auxiliary workers in addition to the operators of the machines. However, it requires space for installation and operation of machines, so it cannot be used depending on traffic or other surrounding conditions. Above all, it would be uneconomical to install small gutter lids one by one. Against this background, various hand-held two-wheeled vehicle type gutter lids for gutter lids have been devised. For example, Japanese Utility Model Laid-Open No. 61-145067 discloses a groove lid lifting machine 50 having the structure shown in FIGS. Reference numeral 51 is a bottom frame, and a motorcycle 52 is attached to the rear end of the bottom frame, and a steering rod 53 is provided upright. On the lower surface of the bottom frame 51, rear claws 54 and front claws 55 that sandwich the groove lid 100 are provided at predetermined intervals. A lever 57 for tilting the front claw 55 forward against the spring 56 during the clamping is attached to the steering lever 53, as shown in FIG. Reference numeral 58 is a tension cable connected to the lever, and 59 is a connecting rod. Further, "Actual Kaihei 2-66887" discloses a gutter lid attaching / detaching machine 60 having the structure shown in FIG. The structure is such that a handle 62 projects from the rear side of the axle of the two-wheeled vehicle 61 and a rear side clamping piece 63 extends from the front side. In the middle of the rear side clamping piece 63, a rotary arm 64 for pinching the lid is pin-connected so as to be vertically rotatable, and the rear side clamping piece 63 and the rotary arm 64 cooperate to clamp the side groove lid. It is supposed to do.

[0003]

[Problems to be solved by the device]

 However, the groove lid lifting machine 50 has the following drawbacks. (A) The tilting mechanism of the front claw 55 is complicated. (B) Since the vehicle control rod 53 having the lever function for lightly lifting the gutter lid is in an upright state with respect to the bottom frame 51, it cannot be so long in relation to the worker's height and a sufficient lever function can be obtained. Absent. (C) Lack of adaptability to differences in the physique of individual workers. (D) Cannot be used for groove lids of different sizes. On the other hand, the gutter lid attaching / detaching machine 60 has a relatively simple structure, but has the same drawbacks as the above-mentioned drawbacks (b) to (d) of the groove lid raising machine 50. Therefore, an object of the present invention is to simplify the structure of a hand-held two-wheeled vehicle used for installation work of a gutter lid, for example, and to operate it with less force. An object of the present invention is to provide a small-sized heavy-duty transportation / installation device that is adaptable to different physical constitutions / shapes of persons and is capable of handling various types of transportation of different shapes / sizes.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, a small heavy object carrying / installing device according to the present invention comprises a two-wheeled vehicle 1 in which wheels 3 are axially fitted to both ends of an axle 2, and is connected to the axle 2 in a rearward direction to rotate up and down. A possible steering wheel 4, a main arm 5 of a predetermined length projecting forward from the axle 2, and a rotary arm 6 of a predetermined length, which is connected to the tip of the main arm 5 so as to be vertically rotatable. The rear claw 7 and the front claw 8 projecting from the lower surface of each of the main arm 5 and the pivot arm 6, the steering wheel 4 and the main arm 5 are rotated around the axle 2. The connecting member 14 to be moved is provided. Then, a rotating means 16 for rotating the rotating arm 6 upward against its own weight is attached. Further, it is advisable to additionally provide a claw interval adjusting means 10 for varying the facing interval between the rear claw 7 and the front claw 8. Further, a crossing angle adjusting means 15 is provided for varying the crossing angle a between the steering wheel 4 and the main arm 5 by changing the length of the connecting member 14. Alternatively, a balance weight 17 that is movable along the longitudinal direction is attached to the steering wheel 4. Then, a plurality of types of rotating arms 6 dedicated to each of a plurality of types of transported objects having different shapes may be attached.

[0005]

[Action]

 For example, using the transportation / installation device of the present invention to sequentially insert gutter lids (transportation items) into concrete road gutters, turn the steering rod 4 downward around the axle 2. The main body 5 is pivoted to lift the pivot arm 6 together with the main arm 5, and if necessary, the pivot means 16 is operated to pivot the pivot arm 6 upward. The gutter lids laid one by one are brought to a position where they can be sandwiched between the rear claw 7 and the front claw 8. In this state, if the vehicle control rod 4 is turned upward and the turning arm 6 is turned downward by the turning means 16, the gutter lid is placed between the rear claw 7 and the front claw 8. It is sandwiched. Then, when the steering rod 4 is rotated downward again, the front claw 8 of the rotating arm 6 which is urged downward by its own weight cooperates with the rear claw 7 to clamp the gutter lid. The gutter lid can be lifted lightly by the lever action of the steering rod 4. In this state, if the gutter lid is carried to its rest position and the operating rod 4 is turned upward, the gutter lid is gently lowered onto the gutter, and the gutter lid is moved by the front and rear claws 7 and 8. The pinch is released. At this time, the gutter lid can be lifted again by rotating the operating rod 4 downward without rotating the rotating means 16. Then, the rotating means 16 is operated to raise the rotating arm 6, and the operating rod 4 is rotated downward to retract the two-wheeled vehicle 1 to complete one cycle of the transportation / installation work. In addition, for objects of different sizes, the claw spacing adjusting means 10 can be operated to change the facing distance between the front and rear claws 7, 8. Further, if the crossing angle adjusting means 15 is operated to adjust the crossing angle a between the steering rod 4 and the main arm 5, the transportation / installation device can be operated most appropriately according to the shape and physique of each worker. It can be changed into an easy form. Alternatively, for gutter lids with different weights, the position of the balance weight 17 assembled to the steering rod 4 can be moved so that the transportation / installation device can be operated more easily. Further, it is possible to replace a different kind of transported object with a rotating arm 6 having a shape suitable for holding it.

【Example】

 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 1 and 2, the schematic structure of the carrying / installing apparatus A1 of this embodiment has a two-wheeled vehicle 1 in which wheels 3 are axially fitted on both ends of an axle 2. On the rear side of the axle 2, a lower end of a steering rod 4 having a predetermined length is rotatably connected, and on the front side of the axle 2, a main arm 5 having a predetermined length is provided to project. A pivot arm 6 of a predetermined length is pin-connected to the tip of the main arm 5 so as to be pivotable up and down. Further, a rear claw 7 and a front claw 8 are provided on the lower surface of each of the main arm 5 and the rotary arm 6 so as to sandwich the transported object B between these claws 7, 8. (See (c) of FIG. 3).

Next, a detailed configuration of the transportation / installation apparatus A1 will be sequentially described. In this embodiment, the wheels 3 are relatively large rubber tires having a diameter of 40 cm and outside. The steering wheel 4 is made of a metal pipe and has a shape in which a horizontally long U-shape is oriented downward, and a horizontal bone 9 is provided in the middle of both legs thereof.

The main arm 5 is made of channel steel or a rectangular tube-shaped material, and its rear end is fixed to the axle 2. A rear claw 7 is provided so as to project downward at a position near the rear end of the lower surface of the main arm 5. In this embodiment, the rear claw 7 is fixed to the main arm 5 by a bolt 10 inserted in a long bolt hole 5a provided in the main arm 5 so as to be movable back and forth by the length of the long bolt hole 5a. However, the rear claw 7 may be directly welded to the main arm 5. At the tip of the main arm 5, a pin hole for inserting the connecting pin 11 is provided horizontally in a direction orthogonal to the arm. Further, a retaining ring 12 is provided at a middle position on the upper surface of the main arm 5.

The rotating arm 6 has a rear end branched into a bifurcated shape so that the front end of the main arm 5 can be sandwiched. The bifurcated bifurcated portion is provided with pin holes through which the connecting pins 11 are inserted, respectively, at two positions in front and in the rear of the bifurcated part. Then, depending on whether the pin holes of the main arm 5 are aligned with the front and rear two of the rotary arms 6, the facing distance between the rear pawl 7 and the front pawl 8 can be set to two different sizes. It can be fitted to each of the transported objects B (see FIG. 4). A hook 13 is attached to the top end of the rotating arm 6. Although not shown, a stopper is provided to restrict the pivot arm 6 from pivoting downward around the connecting pin 11 more than necessary.

The transported object B that can be handled by the transportation / installation apparatus A1 is not limited to the gutter lid. Therefore, the rotating arm 6 may be replaced with a rotating arm 6 such as shown in FIG. 5, for example, in which the shape of the front pawl 8 is different so that the conveyed objects B having different shapes can be reliably sandwiched. I can. A rubber plate or the like for slip prevention may be attached to the front surface of the rear claw 7.

Further, the main arm 5 is provided with a connecting member 14 for keeping a crossing angle a (see (b) of FIG. 3) between the main arm 5 and the steering wheel 4 rotatable around the axle 2 at a desired angle. It is laid across between the retaining ring 12 and the lateral frame 9 of the steering rod 4. A turn bag 15 serving as a means for adjusting the intersection angle a is attached to the middle of the rod-shaped connecting member 14.

A chain (or wire) 16 is stretched between the hook 13 provided on the rotating arm 6 and the upper end of the steering rod 4 in a somewhat loosened state. The chain 16 serves as a rotating means for rotating the rotating arm 6 upward around the connecting pin 11 and lifting it.

Next, the operation of the transportation / installation apparatus A1 will be described with reference to FIG. 3 by taking an example of the work of successively installing the gutter lid (transported material) B in the concrete road gutter. . There are two types of gutter lids B having different sizes. Therefore, first, in order to match the facing interval between the rear claw 7 and the front claw 8 with the size of the gutter lid B, each of the front and rear two pin holes provided in the rear part of the rotating arm 6 is attached to the main arm 5. The connecting pin 11 is inserted according to the pin hole at the front end of the main arm 5, and the rotary arm 6 is connected to the tip of the main arm 5. Further, the turn bag 15 is rotated so as to match the body shape and physique of each operator who operates the transportation / installation apparatus A1 or the usage habit of the apparatus, and the crossing angle a ( Adjust the tilt angle. On the other hand, one of the gutter lids B stacked at the unloading place is laid in advance on the ground so that it can be easily lifted by the transportation / installation apparatus A1.

In this way, when the preparation for use of the transportation / installation apparatus A1 is completed, as shown in FIG. 3 (a), the chain 16 is pulled, and the rotating arm 6 is lifted. It is moved to the position immediately after the gutter lid B.

Then, as shown in FIG. 3B, when the rear claw 7 is brought into contact with the rear side surface of the gutter lid B and the chain 16 is loosened, the rotating arm 6 is moved downward by its own weight. By rotating, the gutter lid B is in a state of being sandwiched between the rear claw 7 and the front claw 8.

Therefore, as shown in FIG. 3 (c), when the steering wheel 4 is rotated downward, the front claw is lifted by the main arm 5 and is biased downward by its own weight. 8 presses the gutter lid B toward the rear claw 7. When the steering wheel 4 is rotated further downward, the gutter lid B is lifted while being sandwiched between the front and rear pawls 7 and 8. At that time, since the steering rod 4 acts as a lever, the force required for lifting is much smaller than that required when holding the gutter lid B by hand.

In this state, the two-wheeled vehicle 1 is moved forward to bring the gutter cover B to a position directly above the installation position, and when the vehicle steering rod 4 is rotated upward, the gutter cover is gently lowered onto the gutter, Moreover, the gutter lid B is released from the front and rear claws 7 and 8 (see (d) of FIG. 3). At this time, if the operating rod 4 is rotated downward without pulling the chain 16, the gutter lid can be lifted again. Then, as shown in FIG. 3 (d), if the chain 16 is pulled up and the turning arm 6 is lifted, the motorcycle 1 is moved backward with the steering lever 4 being turned downward, One cycle of carrying and installation work is completed.

FIG. 6 shows a carrying / installing apparatus A2 according to a second embodiment of the present invention. The difference from the first embodiment is that the balance weight 17 is attached to the steering rod 4. That is, in this embodiment, the central axis hole of the balance weight 17 in the form of a short cylinder is loosely fitted to the guide rod 18 which is provided so as to extend between the cross rail 9 and the top end of the steering rod 4. A set screw 19 for fixing the balance weight 17 is screwed onto the balance weight 17.

With the operation of this embodiment, for a heavier load B, the set screw 19 of the balance weight 17 is once loosened and then moved upward along the guide rod 18. This moving distance is determined by trial and error so that the vehicle manipulating rod 4 can be rotated most easily based on the weight ratio of the transported object B and the balance weight 17.

7 and 8 show a carrying / installing apparatus A3 according to a third embodiment of the present invention. The difference from the first and second embodiments is the configuration of the connecting member 14. That is, the lower end of the connecting member 14 of this embodiment is connected to the retaining ring 12, and the upper end of the connecting member 14 is mounted on the transverse frame 9 of the steering rod 4 and is above the transverse frame 9 for a predetermined length. It is protruding. A locking portion 14A that hooks on the lateral bone 9 is provided at this protruding end. Reference numeral 20 denotes an annular guide member that is attached to the lateral bone 9 and allows the connecting member 14 to be inserted therethrough. Reference numeral 21 denotes a weak support spring that holds the steering rod 4 in an upright state with a predetermined inclination angle, one end of which is fixed to the main arm 5 and the other end of which is in contact with the rear face of the steering rod 4.

Furthermore, the rod-shaped connecting member 14 is divided into upper and lower two parts, 14a and 14b, and a male screw formed on the upper part 14a is screwed into a female screw provided on the upper part of the lower part 14b. It Therefore, in this embodiment, the connecting member 14 can expand and contract within a predetermined length range.

As shown in FIG. 8, the transporting / installing apparatus A3 operates by rotating the steering lever 4 upward as shown in FIG. 7 to sandwich the transported article B between the front and rear pawls 7 and 8. Further, when the steering wheel 4 is rotated downward against the spring force of the support spring 21, the locking portion 14A at the upper end of the connecting member 14 is caught by the lateral bone 9. Therefore, when the steering rod 4 is further rotated downward, the main arm 5 and the rotating arm 6 are rotated upward, and the transported article B is lifted as described above.

In each of the above configurations, the object of the present invention can be achieved even if the design of the detailed structure is changed appropriately. For example, the main arm 5 and the rotating arm 6 may be formed in a ladder shape with their lateral widths widened so as to fit the objects B having different shapes and sizes. The same applies to the front and rear claws 7 and 8. Even if the rotating means 16 of the rotating arm 6 is not provided, it is possible to operate the transportation / installation device by adjusting the rotation angle of the vehicle steering rod 4. Further, the structure of the claw interval adjusting means 10, which is additionally provided as necessary, may be appropriately changed in design so as to sufficiently bear the weight of the conveyed article B.
