Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable trolley, and more particularly to a cable trolley for unwinding a cable bundle wound in a loop along a negotiation route in cable negotiation work.

[0002]

2. Description of the Related Art In a cable arranging operation, there is a method of negotiating while moving a cable bundle wound in a loop. In this operation, if the cable bundle is unwound while being moved, twisting will occur in the cable. Conventionally, an operator hands his hand through the cable bundle, pulls out one loop of the cable several times, and then reverses the cable bundle. It was hand-held from the side of the surface, and was pulled out the same number of times to prevent twisting into the cable.

[0003]

However, in the above-mentioned method, since the work is hand-held by the worker, it is a difficult work accompanied by physical fatigue, and it is necessary to engage a plurality of workers alternately. There was no problem.

[0004] The present invention focuses on the above-mentioned conventional problems, and when performing negotiation while moving the cable along the negotiation route, simply by a single operator while preventing the cable from being twisted. An object of the present invention is to provide a cable trolley capable of performing negotiation work.

[0005]

In order to achieve the above object, in a cable trolley according to the present invention, a rotating body for supporting a cable bundle is mounted on a bogie surface, and the rotating body and wheels of the bogie are rotated. The rotation transmission mechanism is linked to each other by a transmission mechanism, and the rotation transmission mechanism is set to have a rotation ratio that makes the peripheral speed of the wheel of the bogie substantially equal to the peripheral speed of the rotary body, and transmits the rotation from the wheel of the bogie to the rotary body. The configuration was such that clutch means was provided in the path.

A turntable on which a cable bundle can be placed is mounted on the surface of the truck, and the turntable and wheels of the truck are linked by a rotation transmission mechanism. The rotation speed is set so as to substantially match the peripheral speed of the vehicle, and a clutch means capable of intermittently connecting a rotation transmission path from the wheel of the bogie to the turntable is provided.

More specifically, a turntable on which a cable bundle can be mounted is mounted on the surface of the truck, a rotation transmission wheel circumscribing the turntable is provided, and a rotation extraction wheel rolling on the wheel of the truck is provided. The transmission wheel and the rotation extraction wheel are linked by a rotation transmission mechanism, and the rotation transmission mechanism matches the rolling contact peripheral speed between the turntable and the rotation transmission wheel and the rolling contact peripheral speed between the bogie wheel and the rotation extraction wheel. The rotation ratio may be set to be the same, and a clutch means capable of intermittently connecting the rotation transmission path from the wheel of the bogie to the turntable may be provided. In this case, the clutch means may be configured to move the rotation extraction wheel toward and away from the wheel of the bogie.

[0008]

According to the above construction, the cable bundle wound in a loop is placed on the turntable, and when the operator pulls the bogie along the traversing route, the wheel speed of the bogie and the peripheral speed of the turntable are the same. Since the turntable rotates so as to be as follows, a cable length equal to the moving distance of the bogie is extended. Since the cable is sequentially fed out from the outer peripheral side on the turntable, twisting does not occur in the cable.
Since the average diameter of the cable bundle does not always match the turntable, when the cable is twisted, the clutch may be operated to interrupt the rotation transmission and move the bogie. As a result, the cable can be negotiated only by a single worker, and the cable can be prevented from being twisted. A horizontal rotating body may be provided in place of the turntable, and this may be supported so as to be inserted into the center of the cable bundle, and the rotating body may be rotated in synchronization with the wheels.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of a cable trolley according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view and a plan view of a cable trolley according to the embodiment, and FIGS. 2 and 3 are a side view and a plan view of a rotation transmission mechanism.

As shown, the cable trolley 10
Has a carriage plate 12 that forms a rectangular plane, and has a handle 14 in an inverted U shape on one short side of the carriage plate 12.
Wheels 16 are provided at the four corners of the lower surface of 2 so that it can be moved by an operator pushing and pulling.

A turntable 18 is arranged on the upper surface of the truck board 12 and is mounted on the truck board 12 so as to be able to rotate at a fixed position on the truck board 12. In this embodiment, the turntable 18 is configured as a circular ring, and a cable bundle (not shown) wound in a loop on the upper surface.
Can be placed. The turntable 18 may be formed in a disk shape without having a ring structure.

A small-diameter rotary transmission wheel 20 circumscribing the turntable 18 is also mounted on the bogie plate 12, and the rotation of the rotary transmission wheel 20 causes the turntable 18 to be rotated by frictional contact. I have. The outer peripheral surface of the turntable 18 is formed as a knurl surface or a high friction material is adhered to the outer peripheral surface of the rotation transmission wheel 20 so that a number of grooves are formed on the outer peripheral surface of the turntable 18 so that no slippage occurs between the two.

On the other hand, 1 provided on the lower surface of the cart 10
One of the wheels 16 is circumscribed by a rotation extraction wheel 22 having the same diameter as the rotation transmission wheel 20. The rotation extraction wheel 22 is rotatable with the rotation of the wheel 16 by rolling contact with the wheel 16. A number of grooves are also formed on the outer peripheral surface of the rotary extraction wheel 22 to prevent slippage between the rotation extraction wheel 22 and the rubber wheel 16. Further, a spring 24 for rolling the rotary extraction wheel 22 to the bogie wheel 16 is provided in order to surely perform the rolling contact between the two. In this embodiment, one end of the spring 24 is connected to the bogie plate 12, and the other end of the spring 24 is connected to the wheel axle 22 A of the rotary extraction wheel 22 via the axle portion of the bogie wheel 16, so that both are in rolling contact. ing. Of course, it is also possible to adopt a structure that is directly connected to the axle portion of the wheel 16.

The wheel shaft 22A of the rotation extraction wheel 22 and the wheel shaft 20A of the rotation transmission wheel 20 are inserted through a gear box 26 installed on the lower surface of the bogie plate 12, and as shown in FIG. Rotation can be transmitted by engagement of the skew gears 28, 30 attached to the respective axles 22A, 20A. In this case, the gear ratio is set to 1: 1 so that the rotation of the rotation extraction wheel 22 and the rotation of the rotation transmission wheel 20 are the same. As a result, the rotational peripheral speed of the bogie wheel 16 and the rotational peripheral speed of the turntable 18 become the same, and the moving distance of the bogie 10 and the turntable 18
Are made to coincide with each other, and the length of the cable extended from the cable bundle placed on the turntable 18 is made to substantially coincide with the moving distance of the carriage 10.

Here, a clutch means is provided so that a rotation transmission path from the rotation extraction wheel 22 to the rotation transmission wheel 20 can be interrupted. In the embodiment, this is a structure in which the rotary extraction wheel 22 is separated from the bogie wheel 16.
That is, the wheel shaft 22A of the rotary extraction wheel 22 is in a cantilevered state protruding from the gear box 26, and has a structure in which the rotation extraction wheel 22 is fixed to the end of the wheel shaft 22A.
The rolling contact between the rotary extraction wheel 22 and the wheel 16 is released by pulling the tip of the wheel 16 away from the wheel 16. For this reason, the wheel shaft 22A protruding from the gear box 26 is further protruded from the outer surface side of the rotary extraction wheel 22, and the clutch plate 32 is mounted thereon, and the above-described compression spring 24 is mounted on the clutch plate 32, and the spring mounting is performed. A clutch wire 34 is connected to the opposite end. The clutch wire 34 is connected to the clutch lever 36 attached to the above-described carriage handle 14, and forcibly bends the wheel shaft 22A to which the clutch plate 32 is fixed by operating the lever, thereby separating the rotation extraction shaft 22 from the wheel 16. The rotation transmission can be cut off. A bracket 38 is attached to the carriage plate 12 adjacent to the clutch plate 32, and an adjuster 40 for adjusting the wire tension is provided here.

The cable trolley 1 constructed as described above.
When laying a cable using 0, turntable 1
The cable bundle wound in a loop is placed on the
Should be moved. With the movement of the trolley 10, the trolley 1
The turntable 18 rotates so that a cable length of the same length as the moving distance of 0 is unreeled, and the cable is sequentially unreeled from the outer periphery of the cable bundle. . Since the outer diameter of the cable bundle decreases as the cable is extended, the outer diameter of the cable does not match the outer diameter of the turntable 18. Therefore, the cable extension length does not match the moving distance of the carriage as the carriage 10 moves. Is the clutch lever 3
By operating the carriage 6 and moving the carriage 10 while the rotation of the turntable 18 is stopped, an appropriate adjustment can be made.

In the above embodiment, the example in which the turntable 18 is installed on the carriage plate 12 has been described. However, instead of the turntable 18, the turntable 18 is rotated around a horizontal axis such as a horizontal drum inserted into the center of the cable bundle. To provide a rotating body
Similarly, by transmitting the rotation from the bogie wheel 16 and rotating the same, the same operation is obtained. In this case, the peripheral speed of the horizontal drum may be made to match the peripheral speed of the bogie wheel 16.

[0018]

As described above, according to the present invention,
A rotating body that supports the cable bundle is mounted on the truck surface, and the rotating body and wheels of the truck are linked by a rotation transmission mechanism, and the rotation transmission mechanism substantially reduces the peripheral speed of the wheels of the truck and the peripheral speed of the rotating body. The rotation ratio is set to be the same, and the clutch is provided in the rotation transmission path from the wheels of the bogie to the rotating body. In this case, twisting can be prevented from entering the cable, and even if the cable feeding length is different from the traveling distance of the bogie, it can be adjusted by operating the clutch, holding the cable bundle by hand and changing it so that twisting does not enter An excellent effect that unnecessary work can be eliminated is obtained.
