Abstract
The utility model discloses a safety ladder for installing a variable platform insulator. The safety ladder comprises an upper ladder body and a lower ladder body connected with the upper ladder body, wherein a hanging mechanism is arranged on the upper ladder body; the hanging mechanism is a hook; a ladder crawling protecting device is arranged on the upper ladder body; the ladder crawling protecting device is a U-shaped ring which is fixedly connected with the upper ladder body; the upper ladder body is connected with the lower ladder body through a hinge; and a locking device is arranged between the upper ladder body and the lower ladder body. The safety ladder disclosed by the utility model can effectively guarantee personnel safety of operator, avoids safety accident, improves safety coefficient of aerial operation, and can save working time and greatly improves working efficiency; and the safety ladder is simple in structure, convenient to use, and has good popularization value.
Description
Technical field
The utility model relates to a kind of ladder, and especially a kind of change platform insulator is installed and used emergency staircase.
Background technology
Ladder is a kind of apparatus as work high above the ground, is widely used in the industries such as each electric power, communication, electric power.
Be everlasting day when transformer being installed and becoming the platform maintenance, installing and the banding insulation period of the day from 11 p.m. to 1 a.m, normally the bamboo ladder is disposed across on one deck lead-in wire cross-arm, operating personnel are sitting in the work of completing banding insulation on the bamboo ladder, because need continuous shift position to come complete operation in work, have a lot of inconvenience in work, often because operating personnel are careless and inadvertent, to being unfamiliar with of landform, perhaps security incident occurs in accident etc.And adopting this mode longevity of service, efficient is low.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of change platform insulator installation emergency staircase, effectively guarantee operating personnel's personal safety, avoided the generation of security incident, improved the safety factor of work high above the ground, and saved the working time, greatly improved operating efficiency; Simple in structure, easy to use, have good promotional value.
Technical solution adopted in the utility model is:
A kind of change platform insulator is installed and is used emergency staircase, comprises terraced body and connected descending stair body, and upper terraced body is provided with hanging mechanisms.
Hanging mechanisms are hook.
Upper terraced body is provided with the cat ladder protective device.
The cat ladder protective device is U-shaped circle, and U-shaped circle is fixedly connected with upper terraced body.
Upper terraced body and descending stair body are connected through the hinge, and are provided with locking device between upper terraced body and descending stair body.
Locking device is latch.
The beneficial effect that adopts technique scheme to produce is:
1. the utility model articulates firmly, has effectively guaranteed operating personnel's personal safety, has avoided the generation of security incident, has improved the safety factor of work high above the ground, and has saved the working time, has greatly improved operating efficiency.
2. the cat ladder protective device is installed, can effectively evade, dissolve operating personnel because careless and inadvertent, to being unfamiliar with of landform, the perhaps danger that brings of accident has improved the safety of operation greatly.
3. go up terraced body and descending stair body chain connection, can fold when not using, take up room little, easy to store.
4. the utility model is simple in structure, and is easy to use, has good promotional value.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Terraced body on 1; 2 descending stair bodies; 3 U-shaped circles; 4 hooks.
The specific embodiment
A kind of change platform insulator is installed and is used emergency staircase, comprises terraced body 1 and connected descending stair body 2, and upper terraced body 1 is provided with hanging mechanisms.
Hanging mechanisms are hook 4.
Upper terraced body 1 is provided with the cat ladder protective device.
The cat ladder protective device is U-shaped circle 3, and U-shaped circle 3 is fixedly connected with upper terraced body 1.
Upper terraced body 1 and descending stair body 2 are hinged.
Upper terraced body 1 and descending stair body 2 are connected through the hinge, and are provided with locking device between upper terraced body 1 and descending stair body 2.
Locking device is latch.
During use, upper terraced body 1 and descending stair body 2 are opened, locked with latch, operating personnel will install emergency staircase and be articulated on one deck cross-arm by linking up with 4 on two layers of cross-arm, then operating personnel's ascending stair, health enters in U-shaped circle 3, then carries out the task of one deck lead-in wire cross-arm banding insulation.
After finishing using, open the latch on terraced body 1 and descending stair body 2, upper terraced body 1 and descending stair body 2 can be folded.
The utility model adopts hook 4 to articulate, and the cat ladder protective device is set, and operating personnel are carried out duplicate protection, has guaranteed operating personnel's safety, has greatly improved the safety factor of work high above the ground.
