Climbing ladder device for repairing vehicle

Abstract

The invention relates to a climbing ladder device for a repair vehicle. The climbing ladder device cross bars, vertical bars, a vertical plate, a ladder frame rotating device, a ladder frame fixing device and a climbing ladder, wherein the ladder frame rotating device comprises a base, a bearing seat and a rotating disc, the base and the rotating disc are connected through the bearing seat, a bearing is arranged in the bearing seat, the rotating disc can rotate under the action of the bearing seat, the bottom end of the climbing ladder is fixed to the rotating disc, and the other end of the climbing ladder is fixed by the ladder frame fixing device; and when the climbing ladder is used, only the ladder frame fixing device needs to be opened, the climbing ladder is lifted, the rotating discis rotated to the proper angle, the rotating disc is fixed for using, the climbing ladder is provided with a second ladder frame, the second ladder frame can be opened to enable the maintainer to reach the higher place for maintenance work, and the climbing ladder can be firmly fixed on the roof under the action of the ladder frame rotating device and the ladder frame fixing device. The climbingladder device has the advantages of being reasonable in structure, convenient to use, wide in application range and capable of improving the operation efficiency.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, and in particular relates to a climbing ladder device for emergency repair vehicles. Background technique [0002] In the process of maintenance and repair of power equipment, it is sometimes necessary to carry out high-level maintenance operations on high places. Equipment operation and maintenance personnel generally use three methods to reach high places, such as using foot buckles, using aerial work bucket trucks and using ladders. , Mounting pole buckles are generally used in the maintenance of electric poles, but the current maintenance technicians generally have not received training on pole climbing, and cannot use climbing pole buckles safely, and when facing large-diameter poles or non-pole power equipment , the foot buckle cannot be used, and the bucket arm truck for aerial work is generally used in the maintenance of large-scale high-altitude equipment. The use cost is high...

[0002] In the process of maintenance and repair of power equipment, it is sometimes necessary to carry out maintenance operations on higher places. Equipment operation and maintenance personnel generally use three methods to reach high places: using foot buckles, using aerial work arm trucks and using ladders. , Mounting pole buckles are generally used in the maintenance of electric poles, but the current maintenance technicians generally have not received training on pole climbing, and cannot use climbing pole buckles safely, and when facing large-diameter poles or non-pole electric equipment , the foot buckle cannot be used, and the bucket arm truck for aerial work is generally used in the maintenance of large-scale aerial equipment. The cost of use is high, the site requirements are strict, and the use process is cumbersome. The choice of using a ladder does not require professional training, the site requirements are low, and the cost of use is low, but the length of the ladder is too short, sometimes it cannot meet the height requirements, and the ladder is generally fixed on the car body with wire or rope during transportation On the other hand, the pick-and-place process is laborious and time-consuming, and there are potential safety hazards when the binding is not firm
