A-type hanging horse trimming and cutting device and using method thereof

Abstract

The invention provides a kind of A-type hoist repairing and cutting device, comprising a support frame, and the support frame includes two support plates arranged in parallel, and the distance between the two support plates is greater than the length of the lower part of the A-type hoist ear plate to be trimmed, and less than The upper length of the A-type hanging ear plate to be trimmed; several positioning through holes are arranged on the two supporting plates, and positioning rods are arranged in each pair of positioning through holes; horizontal slide rails are respectively provided on both sides of the support frame, and the two The horizontal slide rails are all parallel to the support frame; each of the horizontal slide rails is provided with a hydraulic cylinder that slides with it, and each hydraulic cylinder is connected with a horizontal driving device; the driving rods on the two hydraulic cylinders are opposite to each other. Saw wheels are provided, and band saw blades are mounted on the two saw wheels. The present invention realizes the automatic trimming and cutting of the welding surfaces of multiple A-type hoisting horses on the support frame through the cooperation of hydraulic cylinders, horizontal slide rails, horizontal driving devices and band saw blades, thereby improving the efficiency of repairing and cutting A-type hoisting horses; at the same time, the band saw blades can Realize round-trip trimming and further improve trimming efficiency.

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
