Description

A safety protection device suitable for working at heights

technical field

The utility model relates to the technical field of substation maintenance, in particular to a safety protection device suitable for high-altitude operations, which is used for safety protection during high-altitude operations.

Background technique

The "Electricity Safety Work Regulations" stipulates that any operation performed at a height of 2m or more from the falling height reference plane shall be regarded as high-altitude operation; for high-altitude operations, scaffolding shall be erected first, aerial work vehicles, lifting platforms or other methods shall be adopted. Other fall prevention measures can only be carried out; when there is no scaffolding or scaffolding without railings, and the height exceeds 1.5m, safety belts should be used, or other reliable safety measures should be taken; the hook or rope of the safety belt should be hung on a strong On a firm member, or on a wire rope specially used for hanging the safety belt, and the method of high hanging and low use should be adopted. It is forbidden to hang on moving or unstable objects (such as disconnector support insulators, CVT insulators, busbar post insulators, lightning arrester post insulators, etc.).

It can be seen that reliable fall prevention measures must be used for high-altitude operations before operations can be carried out. In actual electric high-altitude operations, scaffolding, use of aerial work vehicles, lifting platforms, and use of safety belts are relatively common high-fall prevention measures. . The use of scaffolding, aerial work vehicles, and lifting platforms is a reliable fall prevention measure for high-altitude operations, but the aerial work vehicles have a relatively large operating radius, especially for high-altitude operations where substations are partially powered off, and it is easy to accidentally touch live equipment , The operation risk is high. During the driving or transfer process of the aerial work vehicle, it should be driven according to the prescribed route and set up with special personnel to monitor. The operation process is complicated and the operation efficiency is low. For some small-scale maintenance operations, such as power equipment anti-corrosion, maintenance tests, etc., the power outage period is usually short, such as the use of high-altitude operating vehicles and other anti-falling measures, which will make the operation efficiency low, and it is impossible to complete all maintenance operations within the specified power outage time .

Detailed ways

As shown in Figure 1-5, a safety protection device suitable for high-altitude operations includes a fixed base 1, the fixed base 1 includes a sleeve 1.1, the sleeve 1.1 is welded with a cross bar 1.2 up and down, and the other ends of the two cross bars 1.2 are welded There are vertical bars 1.3. Two groups of detachable hoops 2 are welded up and down on the other side of the vertical bar 1.3. Two groups of detachable hoops 2 are used to be installed on the maintenance equipment cement column. Each set of detachable hoops 2 includes a fixed semicircular hoop 2.1, one end of the fixed semicircular hoop 2.1 is welded to the vertical bar 1.3, and the other end of the fixed semicircular hoop 2.1 is connected to the detachable semicircular hoop 2.2 through a locking bolt 2.3. One end of the side wall of the detachable semicircular hoop 2.2 protrudes outwards, and a through hole is drilled at the protrusion. This through hole can be used as the ground connection point 6. The bolt passes through the through hole, and the ground wire 7 is locked at one end by a nut. Tight, while the other end of the ground wire 7 is connected to the ground grid of the substation. A plurality of through holes are drilled on the side wall of the sleeve 1.1, and the load-bearing bracket 3 is vertically inserted into the sleeve 1.1 and fastened by the adjusting bolt 4. And the load-bearing support 3 is provided with a plurality of pedals 5 along the length direction, and the pedals 5 are convenient for maintenance personnel to climb upwards. Each pedal 5 includes a welded threaded sleeve 5.1, and the threaded rod 5.2 is threadedly connected with the threaded sleeve 5.1. The threaded rod 5.2 is horizontally provided with a plurality of protrusions 5.3, which can be assembled and are convenient to carry.

The top of the load-bearing support 3 is provided with a safety belt hanging point 8, and the safety belt hanging point 8 is a ring, and the ring is convenient for the staff to hang the safety belt to ensure the safety during operation and maintenance.

Two groups of connecting plates are welded on the left and right sides of the detachable hoop 2, and a limiting groove 9 is formed between the two groups of connecting plates. Elastic limit head 10 is installed on the outer side of two groups of connecting plates, and elastic limit head 10 is used for limiting the ladder outwards after the ladder is put into the limit groove 9.

The elastic limit head 10 includes a cylinder 10.1 fixed on the connection plate, and the cylinder 10.1 communicates with the through hole on the connection plate. A guide rod 10.2 is arranged inside the cylinder body 10.1, and a spring 10.3 is sleeved on the guide rod 10.2.
