Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable self-propelled vehicle for extending a bypass cable upstairs or downstairs when a temporary power source is required in a building or the like in an emergency. .

[0002]

2. Description of the Related Art A method of extending a bypass cable upstairs or downstairs in a building by manually carrying and extending the cable drum around which the bypass cable is wound is conventionally known. It was taken.

As described above, according to the conventional method, the heavy cable drum is manually carried and the wire is extended while the stairs are raised or lowered, so that there are the following problems. (1) There is a problem in work safety such that the drum may fall down the stairs or the operator may injure his / her back due to the transportation of heavy objects. (2) Due to the nature of the work, it is difficult for one person to work, and multiple people are required. (3) Rapid work is difficult.

[0004]

DISCLOSURE OF THE INVENTION The present invention provides a cable self-propelled vehicle that solves the above problems, reduces the work load, and improves the work safety and efficiency. Is a structure in which a cable drum is rotatably mounted on a frame attached to a vehicle body having an endless track, and the cable is wound and drawn according to the traveling speed of the body.

[0005]

[Embodiment 1] FIG. 1 is an explanatory view of a concrete example of a cable self-propelled vehicle according to the present invention. FIG. 1 (a) is a side view and FIG. 1 (b) is a top view. In the drawings, reference numeral 1 is a vehicle body having an endless track 2, and a cable drum 4 having a gear 41 on its outer periphery is rotatably supported by a rotary bearing on a frame 3 protrudingly attached to the upper portion of the vehicle body 1. There is. 6 is a vehicle body driving wheel, 7 is a track supporting wheel, and the driving wheel 6 is
Is connected to an electric motor (not shown) via a gear,
Driving wheels 6 driven by an electric motor supplied with power from a battery
To drive the vehicle forward and backward. Further, the body 1 is provided with a handle 9 for handling, and the operator holds his hand here to drive. Furthermore, a gear is provided on the outer periphery of the cable drum 4.
41 is carved and meshes with gear 12. The gear 12 is connected to an electric motor (not shown) that operates independently of the electric motor for driving the vehicle body, and receives the power supply from the battery to rotate the cable drum 4. The rotation direction and speed of the cable drum 4 can be freely set by respective control switches of the control box 10 installed near the handling handle 9 and the traveling direction and speed of the vehicle body of the control box 11. A vehicle body support wheel unit 8 including a pair of wheels for traveling on a flat ground is provided below the vehicle body 1.

[0006]

When the cable 13 is wound on the cable drum while climbing up the stairs using such a cable self-propelled vehicle, the following procedure is performed. First, the handling handle 9 is always directed to the upper side of the stairs. Next, the vehicle running switch is turned on to start climbing the stairs, and at the same time, the drum rotation gear 12 is engaged with the gear 41 on the outer circumference of the drum to set the drum rotation switch to the winding side. The rotation speed of the drum is adjusted by the speed regulator of the operation portion so that the winding speed of the cable 13 substantially matches the traveling speed of the vehicle.
By operating in this way, this device winds the cable 13 around the drum 4 while climbing the stairs by the endless track by itself. Manpower is only required to operate the control box and assist the car body.

When a cable is extended using such a cable self-propelled vehicle, it can be carried out by disengaging the engagement of the gears of the cable drum and making the vehicle run. In this case, the cable 13 is pulled out and extended by its own weight.

[0008]

[Embodiment 2] By using such a cable self-propelled vehicle, it is possible to reduce the work load associated with laying a bypass cable in a building and improve work safety and work efficiency. However, in the above-described cable self-propelled vehicle, the vehicle body support wheel unit 12 is always in contact with the flat surface, so that it is not possible to run on the flatland by the endless track, and its position is at the rear end of the endless track 2. Therefore, the endless track 2
The front part is floated from a flat surface and requires a great deal of force when turning or traveling on level ground.

In Japanese Patent Publication No. 1-34188, stays of a horizontal type are pivotally supported at the front and rear and left and right positions of a crawler mechanism, and each step is touched when descending stairs, but a flat surface can be grounded to form an endless track There is disclosed an evacuation vehicle having traveling wheels that can separate the vehicle from the ground surface. However, when the traveling wheels are front, rear, left and right in this way, there is a problem in that a wide space is required for the direction change, and the direction cannot be easily changed at a narrow place such as a stair landing.

2A and 2B are explanatory views of another specific example of the cable self-propelled wire drawing vehicle of the present invention. FIG. 2A is a side view and FIG. 2B is an explanatory view of traveling wheels. This specific example is a self-propelled cable drawing vehicle that solves the above-mentioned problems and facilitates direction change at a narrow place and flatland traveling. In the drawings, the same reference numerals as those in FIG. 1 represent the same parts. In the cable self-propelled wire drawing vehicle of this specific example, instead of the wheel support wheel unit 8 in the wire drawing vehicle shown in FIG. On the body 1
A running wheel 14 which is a free wheel is provided below the wheel 14 ′ and stored in the vehicle body 1.

The operation of winding a cable around a cable drum or pulling a cable out of the drum and extending the wire while climbing the stairs by an endless track using such a self-propelled wire drawing vehicle is shown in FIG. This is similar to the case of a traveling line vehicle, but in this case, by storing the traveling wheels 14 in the vehicle body 1 by the action of the cylinder 15, the traveling wheels 14 can climb smoothly without touching stairs. I can.

Further, in the case of changing the direction or traveling on a level ground with such a cable self-propelled vehicle, it is carried out as follows. First, the traveling wheels 14 are pushed down by the cylinder 15 below the vehicle body 1. As a result, the rear part of the cable self-propelled vehicle floats up and separates from the ground. Then, by depressing the handle portion 9 for handling, the traveling wheel 14 is located in the vicinity of the center of gravity, so that the front portion of the vehicle body easily separates from the ground contact surface with the wheel 14 as a fulcrum. Since the traveling wheel 14 is a free wheel, the direction can be changed around one point,
It is possible to change direction easily in a narrow space such as a stair landing. Further, by pushing or pulling the handle 9 for handling with the endless track separated from the ground surface as described above, the self-propelled extended line vehicle can run on the flat ground regardless of the endless track driving force.

[0013]

As described above, according to the cable self-propelled vehicle of the present invention, it is possible to reduce the work load associated with laying the bypass cable in the building and to improve the work safety and work efficiency. You can In addition, by providing traveling wheels that are moved in and out by a cylinder in the vicinity of the center of gravity of the drawn vehicle, the endless track can be separated from the ground contact surface, making it easy to run on level ground without changing direction in narrow places or the endless track driving force. You can do it.
