Background technique

With the continuous development of science and technology, the degree to which various industries in society rely on electric energy is also increasing. Once a large-scale power outage occurs, the consequences will be disastrous. To ensure safe and stable power supply to the society, it is necessary for transmission lines and substations to maximize To reduce power outage time, in addition to strengthening power grid security technology, at the same time, it is necessary to avoid power outages caused by maintenance through live work, so as to ensure the safe and stable operation of the entire power grid. However, with the sudden increase of power load and the aging of equipment and other reasons, defects such as overheating and loosening of the side clamps of the porcelain bottle pile head of the substation pillars, and bolts often appear. Using existing tools, the personal safety of operators cannot be guaranteed Therefore, it can only be eliminated by power failure, which will inevitably affect the operation of the power grid.

What needs to be pointed out in this case is that the current insulated elevators have great disadvantages:

① Existing insulating ladders cannot guarantee the safety of operators during the equipotential operation of pillar porcelain bottle piles;

② Although the distance is satisfied by using ladders to bind and connect, there are hidden dangers, which cannot be used and promoted normally;

③ Solve the problem of insufficient safety distance for equipotential operators when entering the strong electric field when performing equipotential operations on the side of the porcelain bottle pile head of the substation pillar; at present, when the equipment performs live work to eliminate defects, most of them are carried out in the form of equipotential operations , while using the existing insulating ladders to enter the strong electric field, the equipotential workers have a serious shortage of the combined gap between the charged body and the grounding body, which directly threatens the personal safety of the workers, while the existing lifting platform And other products are not applicable due to various reasons such as safety, practicality, and price.

In the face of the above situation, there are no more than two solutions: one is to erect the ladder at an angle to widen the combination gap; the other is to use ropes to bind ladders such as insulated lifts, insulated flat ladders, and insulated short ladders. "Door" font and "Shang" font. Although it can solve the problem, both methods have potential safety hazards, which are extremely unsafe and helpless, and are not suitable for promotion and normal use.

To sum up, in order to solve the safety problem and improve the application efficiency of substation live work, the upper-shaped combined insulated lift (referred to as "the upper-type ladder") came into being. Therefore, reasonable improvements to the prior art are required.

In order to achieve the above object, the utility model adopts the following technical solutions:

An upper zigzag combined insulating lift is composed of an upper insulating lift, a lower insulating lift, an insulating short ladder platform, an insulating upper pull rod, an insulating lower support rod, and a step holder. The upper insulating lift and the lower insulating lifting There is an adjustment mechanism consisting of lifting pulleys, insulating lifting ropes, step holders, and connecting pulleys between the ladders. The top of the upper insulating lift is provided with an insulating short ladder platform and the insulating short ladder platform is connected to the upper insulating lift. They are perpendicular to each other, and the upper and lower sides of the platform of the short insulating ladder are fixedly connected to the upper section of the insulating lift through insulating upper pull rods and insulating lower struts respectively;

The upper and lower ends of the upper section of the insulating lift are respectively equipped with an upper fixing ring of the wind rope and a lower fixing ring of the wind rope, wherein the bottom of the upper section of the insulating lifting lift and the top of the lower section of the insulating lifting lift are equipped with connecting pulleys; The side is equipped with a self-locking ladder fixer; the adjustment mechanism has an insulated lifting rope.

Correspondingly, the bottom of the lower insulated lift has a base; the self-locking step holder is fixed at the junction of the upper insulated lift and the lower insulated lift.

The beneficial effects of the upper-shaped combined insulating elevator described in the utility model are as follows: generally speaking, it can ensure the personal safety of the operators when performing live work on the above-mentioned equipment, ensure the applicability of live work, and avoid the defects of the above-mentioned equipment. The power outage caused by the power grid provides a strong guarantee for the safe and stable operation of the power grid;

(1) It is technically guaranteed that the combination gap meets the specified requirements during the equipotential operation on the pile head side of the substation, ensures the personal safety of the operators, realizes live work on related equipment, and expands live work projects;

(2) Good economic performance: As a necessary tool for live-line work, the up-shaped ladder is modified without destroying the structure of the lift to ensure that it can be used as a common lift, maximize its application range, and greatly save production costs. It is also more conducive to promotion;

(3) Small footprint, more suitable for equipment-intensive substation operations;

(4) The height of the platform can be adjusted freely to meet different height requirements.

Specifically:

The split combination design of the elevator and the platform ensures the independent use of the elevator, increases the application value, reduces the cost, and avoids repeated purchase of equipment;

The insulating ladder is lighter in weight and easier to connect as an operating platform. At the same time, the use of square tube ladders and shortened step spacing make operators more comfortable;

The double insurance connection mode of pull up and down support makes the working platform more firm and safe;

The fixed cost of the wind rope is easy to maintain, and it is less restricted by the site, which is more suitable for the environmental characteristics of the substation;

The combination of the lifting rope and the pulley block makes the lift easier to take off and land;

The self-locking inter-section fixer makes the inter-section fixation of the elevator more convenient and effectively reduces the number of operators;

Use pulleys to replace the traditional elevator and ladder connection method, effectively reduce friction, prolong life, and save effort in lifting;

The base can make the fixing of the ladder more firm.
