Operating trolley walking freely on steel surface

Abstract

The invention relates to an operating trolley capable of walking freely on the surface of a steel product bent to any angle with the ground through wheels, which is used for arranging various operating devices for spraying sand, paint and the like to perform various operations. The operations of advancing, reversing, steering and operating devices of the trolley are controlled by a remote control operating box or a ground operating box through cables. Monitoring and operating signals are transmitted in parallel or in series. A curved adaptive magnetic sucking disc uses a strong permanent magnet, and a magnetic pole made of iron works close to a walking surface. A spring is arranged between the wheel and the magnetic sucking disc, or the wheel and the sucking disc are integrated to adapt the rise and fall of the walking surface and ensure that a minimum working clearance is kept between the sucking disc and the walking surface. A high-abrasion and high-elasticity material is wrapped outside the wheel and combined with a wheel framework through grooves. The wheels drive a swing frame to adapt transverse inclination of the walking surface. The trolley has adaptive rotary connection for the rise and fall of the walking surface and rotary connection required for steering. A matched supporting vehicle is used for conveying, mounting and storing the trolley.

Description

1. Technical field [0001] In industrial production and daily life, it is often required that certain operating devices can move freely within a certain area. Manually moving these devices can be labor-intensive. For this reason, a trolley that can move freely in a certain area can be designed, the operating device is installed on the trolley, and the operating device can be moved at any time for continuous operation. [0002] Sometimes the operating device also needs to work in areas other than the ground and platforms, such as shipyards, steel structure factories, large-scale machinery factories, etc., when manufacturing and repairing structural parts such as ships, steel beams, trusses, and boxes, it is often necessary to Carry out welding, gas cutting and other work at high places. After the components and equipment are made and shaped, they need to be derusted and painted before they can be delivered for use. These structural parts such as ships, steel beams, quilting f...

AI Technical Summary

Problems solved by technology

In the case that the trolley can be used for free walking, manual operation is often required to meet this requirement, and it is not ideal

[0014] The trolley has a strong suction cup, so it is very difficult to get it off the working surface; sometimes the lower edge of the working surface is a certain distance from the ground, and the trolley cannot drive onto the working surface; there are equipment on the ground that are used in conjunction with the trolley, and a complete set of equipment is required objects, the previous work trolleys did not take this into account
