Tank car inspection safety operation platform based on universal moving wheel control

Abstract

The invention relates to a tank car inspection safety operation platform based on universal moving wheel control. The platform comprises a leg frame, a platform body, a supporting frame and a chassis. The support frame and the leg frame form a door-shaped structure; the platform is assembled between the leg frames through a lifting mechanism; a platform floor is arranged at the lower bottom of the platform, an operation opening is formed in the platform floor, and the platform is further provided with a side opening door and a center opening door; the chassis comprises a supporting bottom plate and a universal moving wheel mechanism; the control system comprises a power supply system, a central controller, an input system and a driving system; and the output end of the input system is connected to the input end of the central controller, the output end of the central controller is connected to the input end of the driving system, and the output end of the driving system is connected to the input end of the lifting mechanism and the input end of the universal moving wheel mechanism so as to control actions of the system. The platform is novel in structural layout electrical control, comprehensive in function and high in safety, and is an important novel tool in the tank car inspection and safety production industry.

Description

technical field [0001] The invention relates to the field of special equipment safety inspection, in particular to a tank car inspection safety operation platform based on control of universally movable wheels. Background technique [0002] Tank car inspection requires inspectors to climb to the top of the tank, disassemble the manhole cover, enter the manhole and perform related work. The inspection work includes disassembling the safety valve, disassembling the manhole cover, macroscopic, grinding, flaw detection, pressure, pressure relief, Nitrogen filling, pressure resistance and other tests required 2 inspectors to go up and down the tank roof more than 5 times. In addition to the rest and extra work during the inspection process, the number of times to go up and down the tank was even more. The tank truck tank top is more than 4 meters high, and the tank body is smooth, so the danger of tank truck inspection is not only the threat of residual gas in the tank, but more ...

AI Technical Summary

Problems solved by technology

The tank truck tank top is more than 4 meters high, and the tank body is smooth, so the danger of tank truck inspection is not only the threat of residual gas in the tank, but more importantly, the risk of falling due to the inconvenience of personnel climbing and working

[0003] At present, various tank car inspection agencies have designed their own inspection platforms according to the inspection site, but there are still many risks due to backward technology and poor applicability.

The inspection platform is generally a metal structure. Due to the heavy weight, several personnel are required to move the platform at the same time, which is time-consuming and labor-intensive. Manual operation may also cause the risk of collision with tank trucks or personnel.

The inspectors are required to be equipped with seat belts when climbing high, but the seat belts will also cause inconvenience in the process of disassembling the manhole cover, and some inspectors even selfishly disassemble the seat belts for the convenience of work, posing a great potential safety hazard

If the personnel in the tank lose consciousness due to suffocation, heatstroke, fall, etc., if the platform is not designed properly, the first aid work will be more difficult and precious golden rescue time will be lost

[0004] For relatively sophisticated inspection equipment and instruments, due to the inability to place on the tank body and the height limitation of itself, the main unit of the equipment can only be placed on the ground, so that it is impossible to introduce advanced inspection equipment to assist the inspection of tank trucks, and it is impossible to scientifically improve the inspection efficiency and strengthen the test effect
