Description

  The present invention relates to a transport installation apparatus that is suitably used to transport and install a concrete product to a predetermined position.

  Conventionally, in construction methods of concrete products that construct sewers, waterways and underpasses, etc., when the open-cut method such as heavy traffic under bridges and underpasses cannot be performed, or when there are restrictions on the sky such as high pressure lines, roads Directly suspended by a mobile crane (heavy equipment), such as when the width is narrow and the installation place of heavy equipment is limited, when the distance between the sheet piles on both sides is narrow, or when installing in a pipeline to correct an aged sewer It is known that a concrete installation product such as a box culvert is transported to a predetermined position and installed in a case where it cannot be installed.

  In the case of the above construction conditions, a construction method using a transport installation device that forms the following three aspects has been known so far.

  First, there is a construction method using a stand for jetting compressed air, that is, an air caster, as a transport installation device (see, for example, Patent Document 1). More specifically, in such a construction method, a concrete product is unloaded from foundation concrete that has been provided with a recess such as a cut in the center in the width direction, and an air caster is installed in the recess located below the concrete product. The air hose connected from the air compressor is blown out from the table to lift and convey the concrete product. After adjusting the blowout amount, it is installed at a predetermined position, and then the air caster is pulled out from the recess. It is a method.

  The following is a construction method using a carriage with a motor having a raising / lowering mechanism for raising and lowering a concrete product with a hydraulic jack and a sliding mechanism in the horizontal direction as a transport installation device (for example, see Patent Document 2). Specifically, in such a construction method, a rail is first embedded in the foundation concrete in advance, and a concrete product is loaded on the cart with the motor that runs on the rail connected by a cap tire cable from a separate engine generator. Then, run the carriage with motor to transport the concrete product to a predetermined position, operate the slide mechanism and lifting mechanism to install the concrete product, and then run the carriage with motor to the original position on the rail It is a method of retreating.

  Further mentioned is a construction method using a transport carriage provided with a rear wheel, a front wheel and an auxiliary wheel for assisting the front wheel in a chassis capable of lifting concrete products as a transport installation device (see, for example, Patent Document 3). Specifically, such a construction method is as follows. In a state where the engine generator, which is a separate body, is connected to the conveyance carriage with a cap tire cable, the conveyance carriage is advanced until its front end is just before the concrete product. By operating the front wheel and the auxiliary wheel at that position, the auxiliary wheel is placed on the bottom plate of the concrete product and the front wheel is lifted. This time, instead of the front wheels, the transport carriage is moved forward with the auxiliary wheels and the rear wheels, and when the front wheels are on the bottom plate of the product, the front wheels are placed on the bottom plate again by the seesaw operation to lift the auxiliary wheels. Then, the front wheel and the rear wheel are advanced until the front wheel is in front of the product, the auxiliary wheel is lowered onto the foundation concrete in front of the product, the front wheel is lifted, and the front wheel is moved forward of the product with the auxiliary wheel and the rear wheel. When it is advanced to the foundation concrete, the front wheel is lowered. Then, with the chassis positioned inside the concrete product, that is, in the upper part of the bottom plate, the insert or hanging tool embedded in the bottom plate of the concrete product is connected to a lifting jig provided on the chassis side and having a lifting and sliding mechanism to lift the product. . In this state, the concrete product is moved forward until the front wheel is in front of the existing product at the front and rear wheels. After that, the auxiliary wheel is placed on the bottom plate of the existing concrete product, the front wheel is lifted, and the auxiliary wheel and the rear wheel are moved forward in place of the front wheel. After that, if the concrete product is transported to a predetermined position, the concrete product is installed by an elevating and sliding mechanism provided on the chassis side. Next, the insert or hanging tool provided on the concrete product is removed from the hanging jig on the chassis side. After that, the carriage is moved backward by the rear wheel and the auxiliary wheel, and when the front wheel is moved back to the outside of the concrete product, the front wheel is lowered onto the basic concrete, and this time, the front wheel and the rear wheel are returned to the original positions. Such a construction method sequentially constructs concrete products by repeating the above steps.

  However, among the construction methods described above, in the construction method using an air caster, basic concrete having a recess such as a cut in the center in the width direction must be placed in advance. In addition, the construction method using a carriage with a motor requires special processing for the foundation concrete such as embedding the rail at a predetermined position of the foundation concrete or fixing the rail with an insert or the like.

  On the other hand, in the construction method using an air caster, the conveyance device does not operate unless the air hose is connected during the conveyance of the product. In addition, in the construction method using a carriage with a motor and the construction method using a conveyance carriage provided with auxiliary wheels, the conveyance device does not operate unless the cap tire cable is connected.

  That is, in the construction method of the concrete product using the conveyance installation apparatus and the conveyance installation apparatus as described above, the degree of freedom when constructing the foundation concrete and the degree of freedom of operation of the conveyance installation apparatus on the foundation concrete are high. The current situation is that it is naturally limited.

On the other hand, in order to improve the degree of freedom of operation of the transport and installation device on the foundation concrete, a method of mounting the engine generator on the transport and installation device itself and allowing it to self-run is also conceivable. In addition, exhaust gas such as greenhouse gas (CO ₂ ) from the engine will fill the construction site, increasing the load on the surrounding environment, including not only the construction site but also engine noise. Can cause.

<Operation description>
Next, an installation method for installing the box culvert B on the foundation concrete K which is an actual construction site by the transport installation apparatus having the above-described configuration will be described with reference to FIGS.

  Thus, the method for installing the box culvert B, which is a concrete product according to the present embodiment, is the position where the box culvert B is placed on the carriage 1 by the transfer device, that is, the motor 50, supplied with power from the battery 8 mounted on the carriage 1. The trolley 1 to the position where the box culvert B carried by the loading / unloading device 70 is transported to a place where the box culvert B is to be installed. 50, and a step of installing the box culvert B at a position where the box culvert B is to be installed by the cargo handling device 70.

  First, FIG. 8 shows a state in which the box culvert B, which is the purpose of conveyance, is placed at a place away from the required installation position by a crane or the like (not shown). From the state shown in the figure, until the motor 50 is driven and close to the box culvert B, the vehicle travels in the “normal traveling mode” at a speed of about 3.6 km / h. When the culvert detection sensor detects that the end surface B11 of the bottom slab B1 is located near the front wheel 3, the electromagnetic brake is automatically activated to avoid a collision between the front wheel 3 and the end surface B11 and is provided on an operation panel (not shown). When the indicator light is turned on, the driver is informed that the end face B11 is close. All subsequent operations are switched from the “normal traveling mode” to the “slow traveling mode” in which the vehicle travels at a speed of about 0.4 km / h. Subsequently, when it is confirmed that the tip auxiliary wheel 2 is positioned on the upper surface B12 of the bottom plate B1 as shown in FIG. 9, the tip auxiliary wheel 2 is placed on the bottom plate B1 of the box culvert B as shown in FIG. The front wheel lifting mechanism 30 raises the front wheel 3 until it is positioned above the upper surface B12.

  Then, as shown in FIG. 11, it is further advanced by the tip auxiliary wheel 2 on the bottom plate B1 and the rear wheel 5 on the foundation concrete K. Thereafter, as shown in FIG. 12, when the auxiliary wheel 4 is on the bottom plate B1 of the product, the auxiliary wheel raising / lowering mechanism 40 is operated to install the auxiliary wheel 4 on the bottom plate B1. To surface. Then, as shown in FIG. 13, the carriage 1 is advanced by the auxiliary wheel 4 and the rear wheel 5 to a position where the front wheel 3 exceeds the bottom plate B <b> 1.

  Then, as shown in FIG. 14, by operating the front wheel lifting mechanism 30 again, the front wheel 3 is lowered onto the foundation concrete K in front of the box culvert B, and the auxiliary wheel 4 is floated from the upper surface B12 of the bottom slab B1. In the state shown in FIG. 15, the front wheel 3 has passed over the bottom plate B <b> 1, and the chassis front half 1 a is intruded into the box culvert B. Then, as shown in FIG. 16, the front and rear cargo handling devices 70 are respectively operated to lift and handle the inner surface of the top plate B <b> 2 of the box culvert B.

  Next, as shown in FIG. 17, the front wheel 3 and the rear wheel 5 are moved forward until the front wheel 3 comes in the middle of the existing box culvert B while maintaining the state in which the box culvert B is lifted, that is, held. At this time, when the bottom plate sensor S detects the proximity to the existing box culvert B in the same manner as described above, it is possible to effectively avoid the front wheel 3 from colliding with the bottom plate B1 of the existing box culvert B. . Then, as shown in FIG. 18, the front auxiliary wheel 2 is placed on the bottom plate B1 of the existing product, the front wheel 3 is lifted, and the front auxiliary wheel 2 and the rear wheel 5 are advanced instead of the front wheel 3 as shown in FIG. In the state shown in FIG. 19, the driver can eliminate the lateral displacement and the contact angle displacement of the box culvert B by the driver appropriately operating the cargo handling slide mechanism 70 a in the front and rear cargo handling devices 70. Can do.

  As shown in FIG. 20, after the box culvert B is positioned at a predetermined position and then the box culvert B is lowered by operating the cargo handling device 70, the box culvert B is accurately positioned as shown in FIG. Can be installed. Thereafter, as shown in FIG. 22, the rear wheel 5 and the tip auxiliary wheel 2 are moved backward.

  As shown in FIG. 23, when the cart 1 is stopped by the electromagnetic brake by the bottom plate sensor S being detected again when the front wheel 3 comes out of the box culvert B, the driver removes the front wheel 3 as shown in FIG. Lower on foundation concrete K and return to the original position with front wheel 3 and rear wheel 5. In this way, the bottom plate sensor S is effectively used not only for the collision of the front wheel 3 with the bottom plate B1, but also for avoiding the tip auxiliary wheel 2 from falling off the bottom plate B1.

  By repeating the above series of steps, the operation of sequentially installing the box culvert B is advanced.

  Further, the cargo handling installation device according to the present embodiment can be suitably installed even with a box culvert B that forms a curved portion as shown in FIG. That is, as shown in the figure, by providing a point 1c on the front half 1a of the chassis, the tip of the front half 1a of the chassis can be safely and without interfering with the inner surface B32 of the side plate B3 of the box culvert B when the box culvert B is installed. Smooth installation is possible.

By adopting the above-described configuration, the transport installation device and the installation method of the box culvert B according to this embodiment are connected to a conventional air hose, a cap tire cable, and the like by being a self-propelled type equipped with the battery 8. Since it can run on the foundation concrete K without any problems, it is possible to effectively avoid special processing on the foundation concrete K, and the degree of freedom of movement on the foundation concrete K is greatly improved. In addition, since it operates with the power from the battery 8, it can contribute to the reduction of greenhouse gas (CO ₂ ) emissions at the construction site, and the generation of noise by the engine generator can be effectively avoided. It has become. As a result, the on-site workability is effectively improved while reducing the load on the surrounding environment.

  In the present embodiment, in order to make it easier to get over the bottom plate B1, a front wheel raising / lowering mechanism 30 for raising and lowering the front wheel 3 and an auxiliary wheel 4 on the rear side of the front wheel 3 are provided. By providing the auxiliary wheel raising / lowering mechanism 40 that raises and lowers the auxiliary wheel 4, the operation when the front wheel 3 gets over the bottom plate B <b> 1 is made much simpler and safer than that described in Patent Document 3 described above.

  In particular, in the present embodiment, both the front wheel lifting mechanism 30 and the auxiliary wheel lifting mechanism 40 are operated in the vertical direction, so that the length of the chassis front half 1a is particularly longer than that disclosed in Patent Document 3. By shortening the length, the mobility on the foundation concrete K, that is, the small turnability is further improved.

  Furthermore, in this embodiment, by providing the steering mechanism ST for changing the direction of the rear wheel 5 close to the driver's seat, the driver can perform driving more suitably, and the front wheel 3 can be moved when the box culvert B is moved. Since the radius of rotation of the box culvert B arranged close to it can be made smaller, precise installation is made easier.

  In addition, in the present embodiment, even if the box culvert B constitutes a curved portion that forms an angle with the connecting portion, the chassis can be installed easily without interfering with the side plate of the existing box culvert B. It is assumed that the tip 1c is formed by cutting off the corner at the tip of the front half 1a.

  In the present embodiment, the cargo handling device 70 is configured to lift the lower surface B22 of the top slab B2 of the box culvert B with the cargo handling platform 7 so that the box culvert B can be installed with inserts, hanging brackets and the like during transportation. There is no need for this, and simple and quick transportation and installation can be performed.

  Since the cargo handling apparatus 70 includes the cargo handling slide mechanism 70a, it is possible to eliminate the slight left-right misalignment during installation and perform accurate installation. Further, a plurality of load handling devices 70, that is, two, are provided in the front-rear direction, and the above-described slide mechanism 70a for load handling also operates independently, so that not only the right and left displacement of the box culvert B but also the box culvert B The horizontal direction, that is, the angle, can also be effectively eliminated only by operating the cargo handling device 70, and can be used for more accurate installation.

  In addition, in this embodiment, a bottom plate sensor S that detects the bottom plate B1 of the box culvert B and an electromagnetic brake (FIG. 3) that stops the carriage 1 when the bottom plate sensor S detects the bottom plate B1 of the box culvert B are provided. Therefore, it is possible to reliably avoid the front wheel 3 from colliding with the bottom plate B1 during forward movement, and to prevent the tip auxiliary wheel 2 from falling off the bottom plate B1 during backward movement.
