Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a hydraulic tool joint for a manipulator for live line work, and more specifically, a hydraulic tool joint for a manipulator for live line work that is attached to the tip drive part of a manipulator for live line work in an aerial work vehicle. This article relates to a hydraulic tool joint for a manipulator used in live line work.

(Prior technology) Conventionally, the work of cutting, stripping, and connecting edge wires, which is high-voltage live wire work on high-voltage overhead distribution lines, has been carried out by two workers wearing insulating protective equipment and holding hydraulic tools at a high height. Get into the work vehicle,
I was working on live wires. However, with this method,
Since the work is carried out while holding a hydraulic tool in the hand, there is a problem in that the worker is at risk of electric shock and is physically fatigued.

In order to solve such problems, it is conceivable to operate various hydraulic tools using a remotely controllable manibulator mounted on the above-mentioned aerial work vehicle to perform the above-mentioned high-pressure pulling down work.

(Problem to be Solved by the Invention) However, the above work is performed by operating various hydraulic tools using a live line work manipulator attached to an aerial work vehicle and setting the hydraulic tools accurately on the hemline. In order to cut, strip, and connect the edge wires, very complicated movements of the manipulator for live wire work are required. This requires a manipulator for live line work to have multiple degrees of freedom, but attempting to deal with this would complicate the structure of the manipulator for live line work, resulting in an increase in the weight of the manipulator for live line work. The problem arises that even the aerial work vehicle must be made larger.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a hydraulic tool joint that can reduce the functions that a manipulator for live line work should be required to perform, and further reduce the weight of the manipulator for live line work.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a hydraulic tool joint for a live-line work manipulator used by being attached to the tip drive part of a live-line work manipulator of an aerial work vehicle. a base housing having a pivot axis extending in the direction; a housing attached at one side to the pivot axis of the base housing; extending through the housing in a fore-and-aft direction and rotatably attached to the housing about a central longitudinal axis; The joint body is provided with a hydraulic tool coupler on the front protruding part and a hydraulic hose coupler on the rear protruding part, and has an operated part that protrudes from the base housing and is directly operated by a manipulator for live line work. and a first
and a second drive means that protrudes from the base housing and has an operated part that is directly operated by a manipulator for live line work, and that rotates the joint body around the longitudinal central axis. It is characterized by this.

(Operations and Effects of the Invention) In the hydraulic tool joint for a manipulator for live line work according to the present invention, the first hydraulic tool joint for a manipulator for live line work is operated by the manipulator for live line work. By driving the second drive means, the hydraulic tool can swing and rotate by itself, and there is no need to equip the manipulator for live line work with these functions. Structure and weight can be reduced.

(Example) Hereinafter, a hydraulic tool joint for a manipulator for live line work according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view of a hydraulic tool joint for a manipulator for live line work according to an embodiment of the present invention.

In FIG. 1, reference numeral 1 designates a hydraulic tool joint, which comprises a base housing 3 having a vertically extending pivot 2, and a pivot 2 of the base housing 3.
It has a box-shaped housing 4 attached to one side thereof. The housing 4 has circular open lower portions on its front wall 5 and rear wall 6, respectively, as shown in FIG.
8 is formed. This housing 4 includes the above-mentioned open lower.

A joint main body 9 is attached to the joint body 9 so as to extend through the joint body 8 in the front-rear direction and to be rotatable around the central axis in the longitudinal direction. This joint body 9 is provided with a hydraulic tool coupler 9a on its front protruding portion, and a hydraulic hose coupler 9b on its rear protruding portion. Various hydraulic tools T equipped with a coupler C1 are connected to this hydraulic tool coupler 9a. In addition, coupler 9 for hydraulic hose
A hydraulic hose H equipped with a coupler C2 is connected to b. Examples of the above-mentioned hydraulic tool T include:
There are sleeve compressors, peelers, cutters, etc. necessary for live wire work.

The hydraulic tool joint 1 according to the embodiment of the present invention has the overall structure as described above, and in this structure, the hydraulic tool T swings around the pivot shaft 2, that is, in the direction of the arrow A. It is also possible to rotate around the central axis in the longitudinal direction of the joint body 9, that is, in the direction of arrow B.

In order to rotate the hydraulic tool T in the direction of arrow A and to rotate in the direction of arrow B, the base housing 1 includes a first drive device 10 as a first drive means and a second drive device as a second drive means. A drive device 11 is provided.

The first drive device 10 has a first drive shaft 12 that is arranged parallel to and spaced apart from the pivot shaft 2, and this first drive shaft 12 extends downwardly from the lower wall of the base housing 1. It is provided with an operated portion 13 that protrudes and extends. This operated part 13 has the shape of a hexagonal head of a normal bolt, and an operating part (not shown) of a manipulator for live wire work engages with this operated part 13. It is designed to operate and operate. A binion gear 14 is fixed to a portion of the first drive shaft 12 inside the base housing 1.

On the other hand, a segment gear 15 is fixed to the lower wall of the housing 4, and this segment gear 15 is connected to a large shaft coaxially arranged with an intermediate shaft 18 arranged between the pivot shaft 2 and the first drive shaft 12. , are operatively coupled to the pinion gear 14 on the first drive shaft 12 via small spur gears 17,18.

The first drive device 10 has the above-described structure, and when the first drive shaft 12 is rotationally driven by a live line work manipulator (not shown), the rotation of the first drive shaft 12 is as follows.
It is transmitted to the segment gear 14 via the binion gear 14 and large and small spur gears 17.18, thereby
The housing 4 is rotated around the pivot 2, which in turn causes the hydraulic tool T to swing.

The second drive device 11 has a second drive shaft 19 that is integrally formed with the pivot shaft 2, and like the first drive shaft 12, the second drive shaft 19 is connected to the lower wall of the base housing 1. The operated part 20 has a shape of a hexagonal head of a normal bolt, and a manipulator for working with live wires is attached to the operated part 20. The operation part (not shown) of the
It is now working. A worm gear 21a is fixed to the interior of the housing 4 of the second drive shaft 19, while a worm wheel 21b engaged with the worm gear 21a is fixed to the joint body 9.

With the above-described structure, when the second drive shaft 12 is rotationally driven by the live line work manipulator (not shown), the rotation of the second drive shaft 12 is caused by the worm gear 21a and the worm wheel. 21b to the joint body 9, whereby the joint body 9
is rotated in its longitudinal section, resulting in rotation of the hydraulic tool T.

As described above, the hydraulic tool joint of the present invention swings the hydraulic tool using the first drive shaft and rotates the hydraulic tool using the second drive shaft, and has the functions that a manipulator for live wire work should have. It performs the same functions as the previous one, reduces the weight of the manipulator, and improves the efficiency of live wire work.
