Description

[Detailed description of the invention] [Field of industrial application] The present invention uses wires such as common horizontal branch lines suspended between utility poles and underground branch lines installed between utility poles and the ground in addition to electric wires as running routes, and ropes. This relates to self-propelled machines used for the delivery of items such as

[Conventional technology]

When carrying out overhead line work, etc., guide ropes and construction work are often transferred between utility poles or between the ground and the top of the pole. However, when transferring the above construction guide rope between utility poles, for example, if there is furniture, a road, a river, etc. between the utility poles, it becomes extremely difficult to perform the work via the ground. In addition, when transferring tools between the ground and the top of a utility pole, if workers use ladders or scaffolding bolts installed on utility poles to go up and down one by one, the work efficiency is poor and there is a risk of increased danger. be.

For this reason, in recent years, construction ropes such as those mentioned above are being used to transfer tools using existing overhead power lines.
Self-propelled machines for electric cables are beginning to be used.
This electric wire self-propelled machine is designed to handle electric wires as shown in Figure 7.
The vehicle is equipped with wheels 101 that use the EW as a running path, and is driven by a motor 103 via a belt 102.The wheels 101 have a U-shaped track guide groove 101a that holds the electric wire EW. was. Additionally, a storage chamber 104 that stores the motor 103 and a wheel mounting portion 1 that supports the wheels 101 are provided.
05 was constructed in one piece.

[Problem that the invention attempts to solve]

However, there are cases where the electric wire is provided with a water draining device or a wire protection cover in the middle, and in such a case, a self-propelled machine equipped with wheels 101 that hold the electric wire EW as shown in FIG. However, the problem with the above method was that it was not possible to get over the wire protection cover. In addition, in order to withstand the bending moment that acts on the pole due to wind pressure loads and uneven tension of the wires, underground branch lines and common horizontal branch lines are installed on utility poles, and if these branch lines can be used as running routes, , it becomes more convenient when carrying out the above-mentioned overhead line work. However, since such a branch line has an insulator part with a large diameter such as a jade insulator in the middle, it has not been possible to use such a branch line with a self-propelled machine equipped with wheels 101 as described above.

Furthermore, in the conventional self-propelled machine as shown in FIG. 9 above, the storage chamber 104 equipped with the motor 103 serving as the rotational drive source and the wheel mounting portion 105 supporting the wheels 101 are integrally constructed. , If the driving path is sloped, even if multiple wheels are installed,
There was a problem in that the weight of the motor 103 caused a load to be applied only to some of the wheels, resulting in a reduction in driving force.

The present invention was developed in view of the above-mentioned circumstances, and can be used for overhead wires and branch lines equipped with wire protection covers, and can be used when running routes are sloped or when wire protection covers are installed. It is an object of the present invention to provide a pendulum-type self-propelled machine that can obtain uniform driving force from a plurality of wheels even when overcoming obstacles such as.

[Means for solving problems]

In order to achieve the above object, the pendulum-type self-propelled machine according to the present invention is formed into a drum shape, and has abrasion resistance at least in a portion of the body peripheral wall excluding a predetermined interval at the center of the waist from the center side to the end surface side. A wheel having a plurality of slip bars with a small number of slip bars, a wheel mounting portion that pivotally supports two or more of the wheels, a drive source mounting portion equipped with a rotational drive source for the wheel, and a wheel that is fixed to the drive source mounting portion and that is attached to the drive source mounting portion. The vehicle is characterized by comprising a connecting arm rotatably coupled to a mounting portion, and a transmission mechanism that transmits the driving force of the rotational drive source to the wheels.

[Effect]

The pendulum-type self-propelled machine configured as described above has wheels shaped like a drum as a whole, so that
Obstacles such as wire covers can easily pass through the constricted portion. In addition, even if the running path of a branch line or the like deviates from the center of the constriction, by riding on the slip bar with low frictional resistance installed on the outer circumference of the wheel body, it will return to the center of the concavity, which is the deepest part, and fall off from the wheel. It won't happen. Furthermore, the wheel mounting section is connected to a drive source mounting section equipped with a rotational drive source via a connecting arm rotatably connected to the wheel mounting section, so that driving on an inclined road is possible. When riding over obstacles or obstacles, only the wheel mounting portions are tilted so that two or more wheels can always be in contact with the running path.

〔Example〕

Hereinafter, the present invention will be explained based on illustrated embodiments.

In Figures 1 to 3, 1 and 1 are wheels made of synthetic rubber such as urethane rubber, and these wheels 1 and 1 are designed to prevent obstacles such as insulators installed on the running path from getting caught in the constriction. It is shaped like a drum so that it can be passed through without any problems. Moreover, these wheels 1, 1 are
The respective wheels 1a, 1a are parallel to each other and are pivotally supported at a predetermined interval by a mounting frame 2, which is a wheel mounting portion. On the body peripheral wall of these wheels 1, 1, there is a fourth
As shown in Figures 1 and 5, the slip bar 1b with low frictional resistance is made of metal, hard synthetic resin, etc., except for the predetermined interval a at the center of the constriction...
A plurality of them (in this embodiment, four on each side) are buried or pasted at equal intervals from the center to the end face side. It is desirable that the predetermined interval a between the constriction centers is set to such an extent that a branch line or an overhead electric wire serving as a running path can be fitted into the constriction. Also,
Each slip bar 1b is inclined in the direction of rotation of the wheel 1 (direction of arrow X) as it goes from the center to the side.If the slip bar 1b is inclined in this way, it can be used for running roads such as branch lines. is slip bar 1
By riding on b, it smoothly slides down to the center. However, the slope of the slip bar does not necessarily have to be made as described above, and by increasing the number of slip bars, etc., the slip bar can be made parallel to the axle 1a when viewed from the side, or inclined in the opposite direction to the slip bar 1b. It can also be used as a slip bar.

Below the axles 1, 1 of the mounting frame 2, a space S is formed as shown in FIG. The space S and the wheel 1
A travel path passage hole 2a is provided through which the lower end of the vehicle can be seen. Needless to say, this travel path passage hole 2a is formed to be large enough to allow obstacles provided on the travel path, such as insulators provided on branch lines, to pass through. Furthermore, the lower part of the mounting frame 2 that forms the running path passage hole 2a is made up of an opening/closing body 2b, and these opening/closing bodies 2b can be connected to the other side by loosening the screws of bolts 2c, 2c provided on one side. It is designed to be able to open and close around a hinge 2d on the side of the door. Therefore, by opening these opening/closing bodies 2b as shown by the dashed lines in FIG. 1, the travel path can be inserted into the space S.

A component storage box 3, which is a drive source mounting section, is connected to the lower part of the mounting frame 2 via a connecting arm 4. In addition to the electric motor 5, this parts storage box 3 houses a battery 6, a relay 7, etc., a limit switch 8 for stopping on the front surface, a push button switch 9 for starting the drive on the rear surface, and a push button switch 9 for starting the drive on the side. is equipped with a power switch 10. That is, after turning on the power switch 10, the push button switch 9 is turned on.
When turned ON, the relay 7 is activated to connect the battery 6 and the electric motor 3, and the electric motor 6 starts operating.
When the limit switch 8 is pressed, the relay 7 disconnects the battery 6 from the electric motor 3 and stops the operation of the electric motor 3.

The connecting arm 4 is a box having a space inside thereof, and is fixed to the storage box 3 and rotatably connected to the mounting frame 2. That is, the mounting frame 2 has a cylindrical swing shaft 9 which is rotatable with respect to the mounting frame 2 and is open at both ends, above the wheels 1, 1 and at the center of the wheels 1, 1 in the longitudinal direction. As shown in FIG. 3, the connecting arm 4 is fixed to one end of the swing shaft 9. Therefore, the mounting frame 2 is configured to be tiltable with respect to the storage box 3.

Next, a transmission mechanism 10 for transmitting the rotational drive of the electric motor 5 to the wheels 1, 1 will be explained with reference to FIG. This transmission mechanism 10 is constructed as follows. That is, the electric motor 5 is connected to the reduction gearbox 11.
A rotary shaft 11a is inserted from the reduction gearbox 11 into the space within the connecting arm 4 for transmitting the reduced rotation of the electric motor 5. On the other hand, a rotary shaft 12 is provided through the swing shaft 9 and is supported on the inner peripheral surface of the swing shaft 9.
The rotating shaft 12 is also inserted into the space within the connecting arm 4, like the rotating shaft 11a. Pulleys 13 and 14 are attached to the rotating shaft 11a and the rotating shaft 12, respectively, and a timing belt 15 made of polyurethane or the like is stretched between these pulleys 13 and 14. 16,
Reference numeral 17 denotes a bearing provided on the shaft bearing portion of the rotating shaft 12. The mounting frame 2 has a drive transmission chamber 2 on the side opposite to the connection surface of the connecting arm 4.
e is formed, and one end side of the rotating shaft 12 and the wheels 1a, 1a of the wheels 1, 1 extend into the drive transmission chamber 2c. A pulley 18 is mounted on the rotating shaft 12, and wheels 1a,
Pulleys 19 and 19 are respectively attached to 1a, and a timing belt 20 is stretched between these pulleys 18 and 19 in a triangular shape as shown in FIG. Through the transmission mechanism 10 having the above configuration, the rotational drive of the electric motor 5 is transmitted to the wheels 1, 1, and the wheels 1, 1 rotate in the same direction.

In addition, 21 is a ring for engaging a rope provided on the rear surface of the mounting frame 2, 22 is a handle used when carrying the pendulum type self-propelled machine, 23 is a charging jack for the battery 6, and 24 is a It's a belt tensioner.

The pendulum-type self-propelled machine configured as described above is the sixth
As shown in the figure, for example, it is used by rotating the wheels 1, 1 using the branch line SW as a travel path, and the wheels 1, 1 start rotating by pressing the push button switch 8, and the pendulum type self-propelled machine When the vehicle reaches its intended location, such as a utility pole, the limit switch 8 comes into contact with the utility pole, etc., thereby stopping the electric motor 5 and completing the travel. and,
When the branch line SW tries to deviate from the center of the constriction of the wheels 1, 1 while driving, the branch line SW shifts to the 7th A.
As shown in the figure, it rides on the slip bar 1b. At this time, if the slip bar 1b was not provided, the branch line SW would be pulled by the rotation of the wheels 1 and move to the side, but by riding on the slip bar 1b, as shown in FIG. 7B,
It slides along the slip bar 1b toward the center of the constriction, and finally, as shown in FIG. 7C, it slides down to a predetermined space a at the center of the constriction where the slip bars 1b, . . . are not provided.

In addition, when traveling on a sloped road such as a branch line, or when overcoming an obstacle such as a jade insulator, the mounting frame 2 tilts around the swing axis 9 as shown in FIG. There is no possibility that one of the wheels 1, 1 will be lifted off the running road. Therefore, the drive of the wheels 1, 1 is reliably transmitted to the traveling road, and stable driving force can be obtained.

It should be noted that the present invention is of course not limited to the above-mentioned embodiments, and in addition to being able to change the mounting direction of the slip bars provided on the wheels as described above, it is also possible to change the mechanism for transmitting the driving force to the wheels and the start/stop of driving, etc. The means can also be modified in various designs.

[Effect of idea]

As is clear from the above explanation, the pendulum-type self-propelled machine according to the present invention can use branch lines and electric wires as running routes without any problems even in the presence of obstacles such as insulators and electric wire protection covers. Furthermore, by allowing the vehicle to pass through obstacles, the running path will not deviate from the center of the wheel and fall out of the wheel. Therefore, it is now possible to exchange ropes and tools using branch lines and electric wires with wire protection covers, which could not be used as travel routes for self-propelled machines, which greatly improves work. It can have great effects.

In addition, when driving on a sloped road or overcoming an obstacle, only the wheel mounting part tilts, so two or more wheels can always be in contact with the road, allowing the vehicle to drive without loss of driving force. It is possible to speed up work by increasing the traveling speed transmitted to the road.
