Hydraulic lifting trolley for loading, unloading and transporting rolling mill bearings

Abstract

The invention discloses a hydraulic lifting trolley for loading, unloading and transporting rolling mill bearings. The hydraulic lifting trolley comprises a trolley frame, the trolley frame is of a frame structure, a vertically-arranged hydraulic oil cylinder is installed at the rear end of the trolley frame, and the hydraulic oil cylinder is vertically upward; the top end of a piston rod is connected with a bearing supporting rod through a connecting piece, and the bearing supporting rod faces the front end of the trolley frame and is used for being arranged in a bearing inner ring in a penetrating mode; the front end of the bearing supporting rod protrudes upwards to form a limiting protruding edge, and the limiting protruding edge is used for clamping a bearing arranged on the bearing supporting rod in a sleeving mode so as to prevent the bearing from slipping; and wheels are arranged at the bottom of the trolley frame; by changing the loading and unloading mode and the conveying mode of the bearing, the labor intensity is reduced, the assembling and disassembling time is saved, and the safety risk existing in the assembling, disassembling and conveying process is reduced.

Description

technical field [0001] The invention belongs to the technical field of loading and unloading tools for rod and wire rolling mill bearings, and in particular relates to a hydraulic lifting trolley used for loading, unloading and transporting rolling mill bearings. Background technique [0002] In rolling mills, bearings are essential parts for rolling mills. When the high-speed wire rod finishing mill is offline, when the bearing needs to be assembled, because the bearing has the characteristics of large diameter (maximum diameter about 600mm) and heavy weight (weight about 40kg), many workers are required to disassemble the bearing every time. Cooperating operations can be completed, that is, the current loading and unloading of rolling mill bearings is carried out by manpower, which is time-consuming and labor-intensive, and there are certain safety risks. Contents of the invention [0003] The purpose of the present invention is to provide a hydraulic lifting trolley fo...

AI Technical Summary

Problems solved by technology

When the high-speed wire rod finishing mill is offline, when the bearing needs to be assembled, because the bearing has the characteristics of large diameter (maximum diameter about 600mm) and heavy weight (weight about 40kg), many workers are required to disassemble the bearing every time. It can only be completed in cooperation with the operation, that is, the loading and unloading of rolling mill bearings is currently carried out by manpower, which is time-consuming and labor-intensive, and there are certain safety risks
