Frame assembly device for double-beam hoist trolley

Abstract

The invention relates to the field of cranes and discloses a frame assembly device for a double-beam hoist trolley. The frame assembly device comprises two linear track beams arranged in parallel, a fixed transverse beam and a movable transverse beam, wherein the fixed transverse beam is arranged perpendicular to the linear track beams and fixedly connected to one ends of the linear track beams; at least two locking mechanisms are arranged on the fixed transverse beam in a sliding manner; the movable transverse beam is arranged perpendicular to the linear track beams and is arranged on the linear track beams in a sliding manner; and at least two locking mechanisms are arranged on the movable transverse beam in a sliding manner. The assembly device is simple in operation, reduces cooperating operations of an operator, guarantees the geometric boundary dimension and geometric tolerance accuracy of a frame of the double-beam hoist trolley, greatly avoids and reduces the phenomena of "three legs" and "track gnawing" and reduces the maintenance and debugging costs.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a double-girder hoist trolley frame assembling device. Background technique [0002] With the rapid development of industry, "intelligent factory, intelligent production, intelligent logistics" has become the mainstream, bringing intelligent chemical factories into the people's field of vision, from CNC machine tools to welding intelligent robots and mechanical professional automatic and semi-automatic assembly lines, traditional machinery The manufacturing industry is also approaching and developing towards intelligence step by step. The European-style crane is based on the European trolley lightweight and modular design concept and advanced manufacturing technology, so that the whole crane has a compact structure, reduced dead weight, lower height, energy saving and consumption reduction, and greatly reduces the user's construction cost of the crane operation workshop and crane operation....

AI Technical Summary

Problems solved by technology

This production process relies entirely on manual inspection to ensure the correctness of the span and diagonal of the crane hoist trolley, which not only has relatively large errors, but also requires a long operation time and requires multiple people to operate

[0004] The small frame has a large tolerance in the external dimensions, and is particularly prone to phenomena such as "gnawing rails" and "three legs"

The labor cost of maintenance and commissioning is high, and the cycle is long, and there is a relatively high risk of working at heights. Sometimes it is necessary to use a crane to lift the trolley down for maintenance. The maintenance takes up a large work space, and the maintenance is laborious and laborious. It also delays normal production and operation.
