Problems solved by technology

However, since the power transmission project itself is a major livelihood project, in a densely populated city, the coverage area of ​​the transmission line will be very large, which also leads to a very heavy work for line erection and maintenance.
If lifts are still used to clear one by one in this case, it will further increase the burden on the staff and greatly reduce the work efficiency, and a little carelessness may also cause danger such as personal injury

Embodiment 1

[0027] Such as figure 1 and 2 As shown in the figure, an operation vehicle for power transmission line maintenance is transformed on the basis of a traditional small truck, including a cab and an open compartment connected behind the cab; the open compartment is equipped with operating devices, and the center of the cab is A control device is installed on the console; the control device is electrically connected with the operating device for controlling its operation, and the control device and the operating device are also connected with a storage battery to obtain electric power.

[0028] The operating device includes a fixed base 1, a lifting hydraulic cylinder 2 vertically installed on the fixed base 1, a horizontal rotating device 3 installed on the movable end of the lifting hydraulic cylinder 2, a horizontal hydraulic cylinder 4 installed on the horizontal rotating device 3, and a horizontal hydraulic cylinder 4 installed on the horizontal rotating device 3. The fixed ...

Embodiment 2

[0037] The difference from Embodiment 1 is that in this embodiment, a camera is installed on the movable end of the horizontal hook 7 or the horizontal hydraulic cylinder 4 to capture working images. The control device also includes a display module. The camera converts the working picture into a signal and transmits it to the central processor in the control device. The central processor transmits the signal to the display module to output the original working picture so that the staff can obtain real-time information in time and then control Operating device.

[0038] Working principle and process of the present invention

[0039] Such as image 3 and 4 As shown, the operator drives the work vehicle to the work site, the driver or other accompanying workers control the control buttons on the center console, and then adjust the lifting hydraulic cylinder 2 to make the horizontal hook 7 reach an appropriate height, and the horizontal hydraulic cylinder 4 to make the horizont...

Abstract

The invention discloses a working device for overhauling transmission lines. The device comprises a fixed base, a lifting hydraulic cylinder vertically mounted on the fixed base, a horizontally rotating apparatus mounted on the movable side of the lifting hydraulic cylinder, a horizontal hydraulic cylinder mounted on the horizontally rotating apparatus, a fixed frame mounted under the horizontal hydraulic cylinder, a horizontal hook mounted at the moveable side of the horizontal hydraulic cylinder and a pair of hydraulic scissors mounted on the fixed frame. The horizontal hook can hook cables and drag them back into the cutting mouth of the hydraulic scissors where the cables are cut off. According to the invention, it is possible to realize the lifting movement in a vertical direction, horizontal rotation and telescopic movement to meet the regulatory requirements for three motion variables of height, length and angle for effectively hooking of branches and old cables at different positions by taking the place of manual climbing for removal activities in the prior art. The use of hydraulic scissors to quickly cut cables and other debris reduces labor intensity greatly and achieves high efficiency and safety.

Description

technical field [0001] The invention belongs to the technical field of transmission line maintenance, and in particular relates to an operation device and an operation vehicle for transmission line maintenance. Background technique [0002] Whether it is the erection of transmission lines or the maintenance of existing lines, it is indispensable to cut off debris such as plant branches near the lines or waste cables generated by the lines themselves to ensure the safe operation of transmission lines. However, since the power transmission project itself is a major livelihood project, in a densely populated city, the coverage area of ​​the transmission line will be very large, which also leads to a very heavy work for line erection and maintenance. If lifts are still used in this case to remove one by one, it will further increase the burden on the staff and greatly reduce the work efficiency, and a little carelessness may also cause dangers such as personal injury. It can be...
