Dam flow channel maintenance platform

Abstract

The invention relates to a dam runner maintenance platform which solves the problems that an existing maintenance platform is complex in structure, poor in flexibility and adaptability and high in maintenance cost. According to the technical scheme, a self-balancing lifting platform is arranged in the middle of a vehicle frame and comprises a front lifter and a rear lifter which are located on thevehicle frame, and a lifting platform supported by the two lifters jointly. A front telescopic operation basket is arranged on the lifting platform. The front telescopic operation basket comprises aleft telescopic bottom plate and a right telescopic bottom plate, a left telescopic basket frame and a right telescopic basket frame correspondingly fixed to the left telescopic bottom plate and the right telescopic bottom plate respectively, and a left tensioning arm and a right tensioning arm. The left telescopic bottom plate and the right telescopic bottom plate are located in an upper slidingway and a lower sliding way of the bottom of the lifting platform respectively, the left tensioning arm and the right tensioning arm are fixed to the lifting platform, and telescopic arms are connected with the corresponding telescopic bottom plates. The platform is simple in structure, good in operation adaptability, good in working reliability, convenient to operate, low in detection cost and high in maintenance efficiency.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a dam flow channel maintenance platform. Background technique [0002] The high-speed water flows through the concrete surface of the flow channel, and the surface concrete will be continuously eroded due to the cavitation effect of the water flow. Moreover, the high-speed sandy water flow will continuously grind the concrete surface and cause damage to the flow channel. Therefore, the flow channel needs to be inspected frequently. During maintenance, due to the large slope and high height of the flow channel, the maintenance personnel need to move a long distance during maintenance. Physical exertion and lack of protection are prone to danger. A new type of dam flow channel maintenance platform is needed to solve the above problems. [0003] During the maintenance of the dam flow channel, due to the restrictions of the maintenance conditions and the maintenance environment, the work in...

AI Technical Summary

Problems solved by technology

[0004] Using the above method requires multiple people to participate in maintenance, which consumes a lot of manpower and financial resources, and with the increase of the length of the flow channel, the engineering quantity will further increase, resulting in an increase in maintenance costs

At the same time, the large-area maintenance platform needs to be fixed in the flow channel, so that it will be dismantled after completion, which will damage the quality of the flow channel bottom plate, which is not convenient for subsequent use
