Vehicle-mounted insulating ladder device

Abstract

A vehicle-mounted insulating ladder device is formed by connecting an insulating ladder to a multifunctional support. The vehicle-mounted insulating ladder device is characterized in that the multifunctional support is provided with a pitch mechanism, the pitch mechanism is composed of a pitch hinged shaft and a pitch hinged sleeve, the pitch hinged shaft is fixedly connected with a rotating tower of the multifunctional support, the pitch hinged sleeve is fixedly connected with the middle lower portion of the insulating ladder, and the pitch hinged shaft and the pitch hinged sleeve serve as a rotating supporting point for pitching motion of the insulating ladder after undergoing sleeved matched installation. An elevation positioning locking mechanism is arranged between the lower end of the insulating ladder and the multifunctional support, the multifunctional support is further provided with an insulating ladder bracket and a locking mechanism, and a frame underframe is arranged at the bottom of the multifunctional support to be connected with an automobile chassis through a bolt connection device. Working at heights can be performed without needing a high position supporting point, the height can be 12-15m, and the stability is good; insulating ladder elevation adjustment is allowed, the insulating ladder can perform 360-degree rotation movement, random conversion of a plurality of operation point positions in the air can be achieved, and operation efficiency is greatly improved; the vehicle-mounted insulating ladder device has no special requirements for installation of various kinds of automobile chassis, and standard matching can be achieved.

Description

technical field [0001] The invention relates to a vehicle-mounted device, in particular to a vehicle-mounted insulating ladder device used for maintenance in the electric power industry. Background technique [0002] The daily maintenance of the power industry, especially the maintenance of substations and distribution networks, often requires high-altitude live work. At present, there are mainly two types of climbing tools for high-altitude live maintenance operations: one is an insulating bucket truck; the other is an insulating ladder. [0003] The insulated bucket arm truck is an advanced high-altitude live working vehicle. It adopts a high-strength folding and telescopic insulating boom with a working bucket at the end of the arm. Its working height can reach 20-30 meters, but its price is high and its structure and operation are complicated. , The requirements for the operation space and site are large, and the flexibility of the transfer operation position in the site...

AI Technical Summary

Problems solved by technology

[0005] The deficiencies of traditional insulating ladder operation methods are mainly reflected in: 1) Insulating ladders other than herringbone ladders cannot be raised and operated without support points in the air, which cannot fully meet many working conditions of electric power maintenance; 2) Insulating ladders The bottom feet cannot be fixed, and when people work at high places, the ladder is heavy at the top and light at the bottom, which poses a danger to safety and stability; 3) Insulated ladders cannot be pitched and rotated in the working state, and the working range on the ladder cannot fully meet the needs, and it is necessary to get off the ladder frequently Move the ladder position

[0006] The shortcomings of the traditional insulating ladder operation method are also reflected in the difficulty of protection during transportation

The long-distance transfer of insulating ladders is generally transported by light trucks; the length of the light truck container is generally 3 to 4 meters, and the insulating ladder is difficult to lay flat in the container, but generally leans on the elevated frame in front of the container. The problem of such transportation is Insulation ladders and lifting frames are prone to friction and damage insulation ladders

The utility model patent 201220122663.7 "A Movable Insulation Ladder Bracket for Electric Emergency Repair Vehicle" authorized on January 16, 2013 provides a solution to this problem, mainly by setting up a reverse door glyph bracket on the front lifting frame and the rear car side. The solution still needs rope binding as an auxiliary method and still cannot completely avoid the friction between the insulating ladder and the bracket; this patented solution only alleviates the transportation problem, and does not involve the inconvenience of the insulating ladder operation
