Multi-fulcrum suspension crane suspension assembly mold and its application method

Abstract

The invention discloses a suspension part assembly jig for a multi-support overhang crane and an application method thereof. The suspension part assembly jig for the multi-support overhang crane comprises a clamping support, two positioning clamping grooves are formed in two opposite rims of the clamping support; and the suspension part assembly jig further comprises a clamping apparatus, the clamping apparatus is a rectangular frame spliced by two support plates and two lateral plates, a plurality of clamping openings are formed in the inner lateral walls of the lateral plates, a plurality of limiting grooves are formed in the rims of the clamping support, and the multiple limiting grooves are located between the two positioning clamping grooves. By adopting manual welding method when mounting suspension parts of the multi-support overhang crane, assembly of component plates in suspension parts is prone to happening larger deviations, so that the problems that rails cannot be adjusted, the crane cannot walk normally, or the rails are excessively worn, happen, while by adoption of the suspension part assembly jig, the parallel error between the base plate and the top plate of the suspension part can be guaranteed to be shorter than 2mm, control of shape and size of whole structure of the suspension part can be achieved just by slightly adjusting the position of each component plate in the manual operation process, and the accuracy of the suspension part in the assembly process can be guaranteed to conform to actual utilization standards.

Description

technical field [0001] The invention relates to an assembly structure, in particular to an assembly mold for suspension parts of a multi-fulcrum suspension crane and an application method thereof. Background technique [0002] In civil aviation maintenance hangars and large-span workshops, if the span of the workshop exceeds 100m, a multi-pivot suspension crane can meet the hoisting requirements. Under different load conditions, the long-span roof has lateral displacement and vertical displacement. How to overcome these complex factors for the crane track to ensure that the crane does not rub against the track during operation is very critical to ensure smooth running. One of the important control measures is: the track suspension can realize both the up and down adjustment of the track height and the left and right adjustment of the track straightness. To meet the requirements, the rail hanger needs to adopt a specific shape, such as figure 2 shown. The hanger is install...

Problems solved by technology

[0003] The purpose of the present invention is to provide a multi-fulcrum suspension crane suspension assembly mold and its application method to solve the problems that the quality error of manual operation is arbitrarily large, and the geometric dimension control cannot meet the design accuracy.

In the large-span workshop, in the manual welding method used in the installation of the suspension parts of the multi-point suspension crane, the assembly of the various part plates in the suspension parts is prone to large deviations, so that the track cannot be adjusted and the crane Inability to walk normally or excessive wear on the track. In this regard, the applicant designed a mold specially used for the assembly of the suspension parts to ensure that the parallelism error between the bottom plate and the top plate of the suspension parts is less than 2mm, and the manual operation is slight Adjusting the position of each part plate can realize the control of the overall construction dimensions of the suspension, so as to ensure that the accuracy of the suspension during assembly meets the actual use standard
