Rapid-installation type traveling trolley connecting structure

Abstract

The invention discloses a rapid-installation type traveling trolley connecting structure and belongs to the field of travelling trolley connecting equipment. The rapid-installation type traveling trolley connecting structure comprises a cross beam (1), a trolley (3) and a pin shaft (2) and further comprises first machining parts fixed to the cross beam, and second machining parts arranged on the trolley (3) and matched with the first machining parts. The first machining parts and the second machining parts each comprise a preset arc blank part and a semicircular ring fixed to the blank part. The arcs in the first machining parts and the arcs in the second machining parts are matched to be combined into an installation arc. The semicircular rings in the first machining part and the semicircular rings in the second machining part are matched to be combined into a circular ring. The two first machining parts are fixedly installed on the beam, and the second machining parts are fixedly installed on the trolley. The pin shaft is arranged in the installation arc; end covers (4) for sealing the pin shaft are arranged at the two ends of the pin shaft; and lock nuts (5) are arranged on the end covers. By means of the structure, the process of installing the beam and the trolley is simple, connecting reliability is high, and the service life of the parts is long.

Description

technical field [0001] The invention relates to a connection structure, in particular to a quick-loading type traveling trolley connecting structure, which belongs to the field of traveling trolley connecting equipment. Background technique [0002] The connection structure of the existing tower crane traveling trolley is to realize the connection between the trolley and the beam through the pin shaft passing through the hole on the beam ear plate and the hole on the traveling trolley respectively. The specific structure is as follows. figure 1 and figure 2 As shown in the figure, holes are first opened at corresponding positions on the beam 1 and the trolley 3, and the pin shaft 2 passes through each hole to realize the connection of the traveling trolley. [0003] The above connection structure needs to ensure the concentricity of all holes in the production process. If the machined plate is welded on the tooling, the requirements for the tooling are higher, and the weld...

AI Technical Summary

Problems solved by technology

[0003] The above connection structure needs to ensure the concentricity of all holes in the production process. If the method of tailor welding the processed plate on the tooling is used, the requirements for the tooling are high, and the control of welding deformation is difficult; if the hole is processed after welding, the requirements for equipment Higher, lower production efficiency; in addition, the pin shaft connected during use is subject to shear force, which requires high material and manufacturing accuracy of the pin shaft, and the accuracy of the structural parts has a great impact on the service life

Generally speaking, the existing structural form has high processing cost, low precision and long production cycle
