Description

Guards for circuit maintenance

technical field

The invention belongs to the technical field of power supply, and in particular relates to a protective device for circuit maintenance.

Background technique

Power supply lines are roughly divided into two types: high-altitude erection and underground burial. Due to the constraints of geographical environment and other conditions, the laying and maintenance of overhead lines are more convenient than buried lines, so overhead lines are more common in power supply cables. Circuit maintenance is an important task that power supply personnel often face. Overhead lines are generally erected on utility poles. Circuit maintenance usually requires climbing operations. Electricians face the risk of falling from high altitudes during the process of climbing poles and during high-altitude operations. At present, the general protective measure is to wear seat belts with you. The correct use of seat belts requires high hanging and low use. However, there is often no place to hang seat belts during pole climbing, and sometimes even when you climb to the pole At the top, it is also difficult to find a suitable place to hook the seat belt, which makes the seat belt unable to play a role in safety protection, and sometimes even becomes a burden to the electrician when climbing the pole. , it has become an unsafe factor for working at heights. In addition, climbing the pole will consume a lot of physical strength of the maintenance personnel, and the range of activities of the climbing personnel is relatively limited, and they cannot fully liberate their hands and feet. These will not only increase the labor intensity of the maintenance personnel, but also reduce the maintenance work efficiency, and the physical strength is invisible. It will also further increase the risk of working at heights.

Fixed connection, the top end is connected with the working platform, and each pillar is synchronously extended and retracted, which can realize the second-level elevation and lowering of the working platform.

Further, a C-shaped anti-skid checker plate is laid on the working platform, so that maintenance personnel can walk on the working platform and take a rest on the working platform.

Further, the guardrail is erected above the work platform through a plurality of guardrails, and a guard net is arranged between the guardrails.

Further, a switchable side door is also provided at the opening of the guardrail.

Further, an electric control box is arranged on the inner side of the guardrail, and each of the electric telescopic rods is electrically connected to the electric control box.

Further, the working platform is also provided with a tool box, which can be used for placing circuit maintenance tools.

The present invention also includes other components that can be used normally, all of which are conventional means in the field. In addition, devices or components not limited in the present invention, such as: electric telescopic rods, universal wheels, safety belts and electric control boxes and its internal circuit settings, etc., all adopt the existing technology in the field.

The beneficial effects of the present invention are as follows:

The protection device for circuit maintenance provided by the present invention adopts a two-level liftable maintenance frame working platform to assist in circuit maintenance, changes the traditional climbing pole operation mode, greatly reduces the labor intensity of maintenance personnel, and avoids the risk of falling from high altitudes. And it expands the range of activities of maintenance personnel, liberates hands and feet, which is conducive to improving the efficiency of maintenance work and improving the safety factor of operation.

Detailed ways

The technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of the embodiments.

It should be noted that the orientations or positional relationships indicated by the terms "upper", "lower", "inner", "outer", etc. are all shown based on the accompanying drawings and are only for convenience of description.

Example

As shown in Figure 1-2, the protective device for circuit maintenance includes an electric pole 1 and a maintenance frame surrounding the outside of the electric pole. The maintenance frame includes a support base 2, and the bottom of the support base is fixed with three tripods. Telescopic outriggers 3, three telescopic pillars 4 are evenly fixed above the base, a working platform 5 is arranged above each of the pillars, a protective fence 6 is arranged above the working platform, and the supporting base, the working platform and the The guardrails are all C-shaped, and the openings of the three are in the same direction. The openings are used for the entry and exit of the poles, and a safety belt 7 is hooked on the guardrails.

The outrigger is an electric telescopic rod, the top end of which is fixedly connected with the support base, and the bottom end is rotatably hinged with a foot plate 8 .

A universal wheel 9 with a brake is also arranged below the foot plate, which facilitates the push-pull movement of the entire maintenance rack and the foot-fixing in place.

The support column is an electric telescopic rod, the bottom end of which is fixedly connected with the support base, and the top end is connected with the working platform.
