Abstract

The utility model relates to a line inspection and maintenance vehicle, which includes a pulley, a boom, and a seat plate. Or two splints that move outward, and an operating handle is provided on the threaded shaft. The utility model has the advantages that: it has a braking function, and the operators on the vehicle can control the moving speed of the inspection and maintenance vehicle through the manual brake, so that accidents will not occur due to unfavorable dragging by ground personnel, and potential safety hazards can be eliminated.

Description

Line maintenance vehicle

technical field

The utility model relates to maintenance equipment for power transmission and transformation lines, in particular to a line maintenance vehicle for on-line operations.

Background technique

At present, the on-line operation and maintenance vehicle used for power transmission line maintenance is mainly composed of a pulley on the cable, a boom connected to the pulley, and a seat plate connected to the boom. When the maintenance vehicle of this structure moves on the cable, it depends on the ground personnel to control the direction by the rope connected to the flying vehicle. Its disadvantage is that if it encounters a slope, when going downhill, the ground personnel will not be able to drag it easily, causing the speed of the speeding car to slide too fast. When going uphill, it is also easy to cause the speeding car to slide back due to insufficient drag force of the ground personnel, which is prone to safety accidents.

Contents of the invention

The purpose of the utility model is to provide a safe and reliable line maintenance truck that maintenance personnel can control by themselves.

The purpose of this utility model is achieved in the following way: a line maintenance vehicle, including a pulley, a boom, and a seat plate, is characterized in that a manual brake is provided at a pulley, and a threaded shaft with positive and negative threads is provided. Two splints that can move inward or outward along the shaft at the same time, and an operating handle is provided on the threaded shaft.

In the manual brake, the opposite surfaces of the two splints are provided with anti-slip rubber layers.

The utility model has the advantages that: it has a braking function, and the operators on the vehicle can control the moving speed of the inspection and maintenance vehicle through the manual brake, so that accidents will not occur due to unfavorable dragging by ground personnel, and potential safety hazards can be eliminated.

Description of drawings

Fig. 1 is a structural representation of the utility model;

Fig. 2 is the structural representation of the utility model pulley;

Fig. 3 is a structural schematic diagram of the manual brake of the present invention.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described further:

As shown in Figures 1, 2, and 3, two pulleys 1, 2 are arranged on pulley frames 10, 11 respectively, and booms 3, 4 are connected to each other on the pulley frames, and seat plates 9 are connected to the bottoms of the two booms. , a manual brake is provided at a pulley, and the support frame 8 of the manual brake is connected with the pulley frame 10 as a whole. The support frame is provided with a threaded shaft 7 with positive and negative threads. Two splints 5 that move outward, one end of the threaded shaft passes through the support frame and is connected with the operating handle 6 . The opposite surfaces of the two splints are provided with anti-slip rubber layers.

When working, hang the pulley of the flying car on the cable, and make the cable between the two splints of the brake, turn the handle in one direction, so that the two splints move inward along the axial direction at the same time, that is, move toward each other, and the wire can be clamped. The cable acts as a brake. Rotate the handle in the other direction, and the two splints move outward along the axis at the same time, that is, reverse movement, and the cable can be released and the brake can be released.

Claims (2)

1, a kind of line maintenance carries car, comprise pulley, arm, seat board, it is characterized in that being provided with manual brake at a pulley place, its have right-and-left threaded thread spindle be provided with can be simultaneously vertically in or two clamping plate outwards moving, thread spindle is provided with operating grip.

2, line maintenance according to claim 1 carries car, it is characterized in that described manual brake, and the opposite face of its two clamping plate is provided with the anti-slip rubber layer.
