A-type lifting lug trimming device and using method thereof

Abstract

The invention provides an A-type lifting lug trimming device. The device comprises a supporting frame, the supporting frame comprises two supporting plates arranged in parallel, and the distance between the two supporting plates is larger than the length of the lower portion of an A-type lifting lug plate to be trimmed and smaller than the length of the upper portion of the A-type lifting lug plate to be trimmed; a plurality of positioning through holes are oppositely formed in the two supporting plates, and positioning rods are arranged in each pair of positioning through holes; horizontal sliding rails are arranged on the two sides of the supporting frame correspondingly, and the two horizontal sliding rails are parallel to the supporting frame; each horizontal sliding rail is provided with a hydraulic cylinder in sliding fit with the horizontal sliding rail, and each hydraulic cylinder is connected with a horizontal driving device; and saw wheels are oppositely arranged on driving rods of the two hydraulic cylinders, and band type saw blades are arranged on the two saw wheels. According to the device, through cooperation of the hydraulic cylinders, the horizontal sliding rails,the horizontal driving devices and the band type saw blades, multiple A-shaped lifting lug welding faces on the supporting frame can be automatically trimmed, so that the A-shaped lifting lug trimmingefficiency is improved; and meanwhile, the band type saw blades can achieve back-and-forth trimming, so that the trimming efficiency is further improved.

Description

technical field [0001] The invention belongs to the field of pruning and cutting, and in particular relates to a type A hoisting horse pruning and cutting device and its application method. Background technique [0002] Hanging horses are widely used in the process of ship construction, general assembly, and loading, and the number of uses is very considerable. There are five types of hoisting horses commonly used on ships (Type A, Type B, Type C, Type D, and Type E), which are used for segmented lifting, turning, and loading operations. The usage of A-type hoists accounts for about 60% of the total usage of hoists. According to the design load, the A-type hoisting horse is subdivided into five specifications: A-20t, A-30t, A-40t, A-50t, A-60t, and A-20t, A-30t, A-40t, A-50t The hanging holes of the A-type hoisting horses are all 40mm, while the A-type hoisting holes of the A-60t are 50mm; secondly, there are five specifications A-20t, A-30t, A-40t, A-50t, and A-60t The o...

AI Technical Summary

Problems solved by technology

[0003] In order to reduce the production cost, most users will choose to recycle the A-type hoist for reuse, and the reused A-type hoist will inevitably have a lot of solder left, which makes the welding surface of the A-type hoist uneven. If the welding surface of the Type A hoist is trimmed and used directly, it will not be able to ensure the effective connection between the Type A hoist and the installation plane, resulting in the separation of the Type A hoist from the installation plane during the hoisting process, causing potential safety hazards

[0004] In the prior art, A-type hoisting horses are generally repaired by manual cutters, which is not only inefficient, but also causes a huge workload on workers, and there is also a phenomenon of molten iron hanging on manual cutters, which affects the repair and cutting quality
