Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is equipped with a cable turbulence prevention device capable of winding up an aerial cable neatly on a drum mounted on a chassis. It relates to a cable work vehicle.

[Prior Art] A conventional cable working vehicle 10 has an undercarriage as shown in FIG.
A drum support arm 11 mounted on 10a is simply equipped with a drum 12 for winding or unwinding a plurality of cables (in the figure, one drum is inserted through a rotary shaft). Therefore, when the cable W is wound around the drum 12 or unwound from the drum 12, the cable W is currently guided by a wide guide roller 13 provided on the ceiling of the operation cabin 10b. there were.

[Problems to be solved by the device]

Therefore, when the cable W is wound on the drum 12 mounted on the conventional cable working vehicle 10 shown in the same figure, since it is only guided by the guide roller 13, irregular winding occurs between the wound cables W. It is easy to occur and it is impossible to store the cables in an orderly manner. Therefore, when the cable W wound on the drum 12 is used by being unwound, the cable W cannot be unwound smoothly, so that the cable W cannot be removed or There were various problems such as inefficient installation work.

[Means for Solving the Purpose and Problem of Invention]

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to randomly wind a cable that winds an aerial cable or the like around a drum mounted on a chassis. To provide a cable working vehicle equipped with a protection device, and for that purpose, a cable working vehicle equipped with a drum for winding and unwinding a cable on a chassis, the base end of which is pivotally supported on the chassis. A telescopic cylinder is erected vertically to extend and retract, a four-sided roller is attached to the tip of the telescopic cylinder, and both ends of a rocking cylinder for rocking the telescopic cylinder to the left and right are pivotally supported by the telescopic cylinder and a chassis. .

[Action]

Since the invention of the present application adopts the above-mentioned configuration, it is possible to wind the cable in an orderly manner without causing irregular winding when winding the cable on the drum, without being influenced by the diameter of the cable and the diameter of the drum. Yes, and the cable can be unrolled very smoothly. In addition, the telescopic cylinder with the four-sided roller attached to the tip of the present invention is constructed so as to be erected vertically and vertically, and the rocking cylinder for rocking the telescopic cylinder to the left and right is arranged on the side surface of the telescopic cylinder. Even when it is installed upright on the chassis, both cylinders do not interfere with the drum when the cable is wound and unwound, and the chassis can be effectively used. Therefore, cable laying work and withdrawal work can be done quickly,
In addition, it becomes possible to carry out efficiently.

〔Example〕

An embodiment of the cable working vehicle according to the present invention will be described in detail below with reference to FIGS. 1 and 2.

In the figure, 1 is a cable working vehicle according to the present invention, and 2
Is a drum support arm mounted on the left and right on the chassis 1a, and a tube base end is pivotally attached to a rod end of an undulating cylinder 3 which is pivotally mounted on the chassis 1a near the base end of one drum support arm 2. The drum supporting arm 2 is configured to be undulated by a predetermined angle in the front-rear direction by the expansion and contraction operation of the undulating cylinder 3.

4 is a hydraulic motor, and the driving force of the hydraulic motor 4 is
A drum shaft 2a and a rotary arm that are installed between the left and right drum support arms 2 via a plurality of sprockets and chains (not shown in the figure) built in the right drum support arm 2.
The drum 5 that is transmitted to the drum shaft 2a and is inserted into the drum shaft 2a is rotated.

Reference numeral 6 denotes a cable irregular winding prevention device configured by mounting a four-sided roller 6b on the rod tip of an extendable cylinder 6a standing between the drum 5 on the chassis 1a and the driving cabin 1b. Adjusting the level of the four-sided roller 6b by the extension / contraction operation of the extension / contraction cylinder 6a having the four-sided roller 6b attached to the tip of the rod, and the extension / contraction of the rocking cylinder 7 pivoted at both ends to the side portion of the extension / contraction cylinder 6a and the chassis 1a. In operation, the telescopic cylinder 6a is swung left and right, and the cable W inserted through the four-sided roller 6b is swung right and left along the drum 5.

Hereinafter, the operation of the cable working vehicle according to the present invention will be described based on the above configuration.

That is, the cable working vehicle 1 according to the present invention comprises a drum 5 supported by drum supporting arms 2 mounted on the chassis 1a on the left and right sides.
The drum supporting arm 2 is raised and lowered by a predetermined angle by the expansion and contraction operation of the hoisting cylinder 3 pivotally attached to the one drum supporting arm 2 near the base end, so that the drum 5 can be attached to and detached from the drum supporting arm 2. A four-sided roller that facilitates the rotation of the drum 5 by the hydraulic motor 4 arranged on the right side of the drum support arm 2 and that constitutes the cable turbulence prevention device 6 that is erected between the drum 5 and the operation cabin 1b. The height of 6b is adjusted (adjusted according to the size of the diameter of the drum of the drum 5 mounted on the drum support arm 2) by expanding and contracting the telescopic cylinder 6a. The rocking cylinder 7 pivotally mounted on the side of the roller 5 is expanded / contracted to rock the four-sided roller 6b to a predetermined width, and the cable W is traversed in the winding order to be wound up on the drum 5. The cable W is wound up in an orderly manner so that irregular winding does not occur in the cable W.

[Effect of device]

INDUSTRIAL APPLICABILITY As described in detail above, the present invention is a cable working vehicle in which a drum for winding and unwinding a cable is mounted on a chassis, and a telescopic cylinder having a base end pivotally supported on the chassis is vertically extendable. Since a telescopic cylinder is mounted on the tip end of the telescopic cylinder and both ends of the rocking cylinder for rocking the telescopic cylinder to the left and right are pivotally supported by the telescopic cylinder and the chassis, the diameter of the cable, the drum When the cable is wound on the drum, the winding can be done in an orderly manner without causing irregular winding, and the cable can be unrolled very smoothly. In addition, the telescopic cylinder with the four-sided roller attached to the tip of the present invention is constructed so as to be erected vertically and vertically, and the rocking cylinder for rocking the telescopic cylinder to the left and right is arranged on the side surface of the telescopic cylinder. When winding up the cable even with it standing on the chassis,
The chassis can be effectively used without both cylinders interfering with the drum. Therefore, the cable laying work and the withdrawal work can be carried out quickly and efficiently, and various excellent effects can be obtained.
