Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a self-propelled moving device for lifting a tool or a heavy object from the ground to a high place for performing a certain work at a high place such as a power transmission tower.

[0002]

[Prior art]

 In order to carry out constant work at high places such as power transmission towers, etc., to raise tools from the ground to high places, it has been customary in the past to wire up a basket with a tool and the like at the tip and to wind and unwind it. The method is to prepare a pulley for people to let the wire scoop the wire in high places.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional method, there is a disadvantage in that the work efficiency is low because a person works at a high place and the work is dangerous. In addition, there is a drawback that it takes time to prepare, such as temporarily installing a winch on the ground in order to raise heavy objects. Therefore, the present invention enables a tool or a heavy object to be lifted from the ground to a high place with a simple device without requiring the work of a person at a high place.

[0004]

[Means for Solving the Problems]

 In the present invention, a front drive unit, a rear drive unit and a base are provided as a self-propelled moving device. The front drive unit includes a pair of drive wheels that are arranged in the front-rear direction, an auxiliary wheel that forms a set that is arranged in the front-rear direction with a moving rail sandwiched between the drive wheels, and the moving rail that has the moving wheels. A spring that is tightened between the auxiliary wheel and the auxiliary wheel, and a motor that drives the drive wheel are provided. Similarly, the rear drive unit also includes drive wheels forming a set arranged in the front-rear direction, auxiliary wheels forming a set arranged in the front-rear direction with a moving rail interposed between the drive wheels, and the moving rails. A spring that tightens between the drive wheel and the auxiliary wheel and a motor that drives the drive wheel are provided. The base connects the front drive unit and the rear drive unit.

[0005]

[Action]

 In the self-propelled mobile device of the present invention configured as described above, the moving rails are arranged from the ground to a high place, and the motors of the front drive unit and the rear drive unit are driven by the operation from the ground to move forward. The device freely moves from the ground to a high place along the rails for movement due to the frictional force of the drive wheels and auxiliary wheels of the drive unit and the rear drive unit and the tightening load of the springs, and places tools and heavy objects on the base. This makes it possible to lift tools and heavy objects from the ground to high places without requiring human work at high places, and to increase the load capacity by increasing the motor output and spring tightening load. It will be possible.

【Example】

 FIG. 1 is an example of a self-propelled moving device of the present invention. The self-propelled moving device is roughly divided into a front drive unit 10, a rear drive unit 20, and a base 50.

The front drive unit 10 is made of a material having a high coefficient of friction, such as hard urethane rubber or FRP, instead of a material having a low coefficient of friction, such as resin or steel. One set of drive wheels is provided on the left and right as shown by drive wheels 11 and 12, and each is made of a material having a high friction coefficient such as hard urethane rubber or FRP. As shown in auxiliary wheels 13 and 14, left and right moving rails 1 and 2 are provided between the driving wheels 11 and 12, respectively. It is installed so as to sandwich it.

The moving rails 1 and 2 are formed into a shape bent into a rectangle as shown in FIG. 1 (C), and are parallel to each other from the ground to a high place, for example, as shown in FIG. Auxiliary wheels 13 and 14 are inserted inside the landing so as to form a special landing.

Further, in the front drive unit 10, a timing pulley 15 is attached to the shafts of the drive wheels 11 and 12 and a timing belt 16 is looped over the shafts so that the drive wheels 11 and 12 share the front shaft. Then, the spur gear 17 is attached to this, the motor 18 is arranged, the reduction gear 19 is attached to this, the spur gear 17 and the reduction gear 19 are meshed, and the motor 18 is driven to drive the drive wheels 11 and Allow 12 to rotate.

Further, compression springs 31 and 32 for tightening the moving rails 1 and 2 between the drive wheels 11 and 12 and the auxiliary wheels 13 and 14 are provided on the upper surface of the front drive unit 10, and are attached to the shafts 33 and 34. Tighten the compression springs 31 and 32 by inserting and placing them, forming a screw on the upper part of the shafts 33 and 34, engaging the tightening nuts 35 and 36 with this, and adjusting the tightening nuts 35 and 36. Allow the load to be adjusted.

The rear drive unit 20 is also configured in exactly the same way, and the parts corresponding to the respective parts of the front drive unit 10 are assigned the reference numbers of the 20s or 40s instead of the reference numbers of the 10s or 30s. Indicate.

The base 50 connects the front drive unit 10 and the rear drive unit 20, and is made rotatable with respect to the front drive unit 10 and the rear drive unit 20, for example, on which tools and heavy objects are placed. . Specifically, as shown in FIG. 2, a case 51 serving as a cargo bed is attached to the base 50, and a shellfish or a heavy object is put therein.

In order to move the above-described self-propelled mobile device from the ground to a high place, the motors 18 and 28 of the front drive unit 10 and the rear drive unit 20 are driven in one direction by a wireless or wired operation from the ground. . In this case, as a power source, a storage battery may be mounted on the self-propelled mobile device, or a power supply line may be provided in parallel with the moving rails 1 and 2 to supply power from the ground to the self-propelled mobile device. You may. Since the drive wheels 11, 21 and 12, 22 and the auxiliary wheels 13, 23, 14, and 24 are fastened between the moving rails 1 and 2, the motors 18 and 28 are driven in one direction so that the self-propelled moving device is driven. Moves from the ground along the moving rails 1 and 2 to a high place, and by placing a tool or a heavy object on the base 50 when it is on the ground, the tool can be operated without requiring human work at a high place. And heavy objects can be lifted from the ground to high places. By increasing the output of the motors 18 and 28 and the tightening load of the compression springs 31, 32 and 41, 42, it is possible to increase the transportable weight. When the motors 18 and 28 are driven in opposite directions, the self-propelled moving device descends from a high place to the ground along the moving rails 1 and 2.

It should be noted that only one moving rail may be provided, and the self-propelled moving device may be provided with one set of drive wheels and one set of auxiliary wheels for the front drive unit and the rear drive unit, respectively.

[0015]
