Simple trolley used for hoisting rolling line heat preservation roller and application method of simple trolley

Abstract

A simple trolley used for hoisting a rolling line heat preservation roller comprises a frame, a hook and a balance weight. The simple trolley is characterized in that the frame is a rectangular framework made of steel pipes, and front wheels (3) and rear wheels (3) are arranged at the four corner edges of the frame; a third supporting column (7) is vertically arranged in the middle of the frame steel pipe between the two rear wheels, and a second supporting column (5) is vertically arranged in the middle of the frame steel pipe between the two front wheels; the third supporting column (7) and the second supporting column (5) are the same in height, a beam (4) is welded and fixed between the third supporting column (7) and the second supporting column (5), an extending section is arranged on the part, at the front portion of a trolley head, of the beam (4), and the hook (1) is welded and fixed to the end portion of the beam (4); and the balance weight (6) is arranged at the rear portion of the rectangular framework of the frame. The simple trolley has the beneficial effects that the trolley is simple in structure and convenient to operate, the trolley is used flexibly, overhauling manpower and equipment input for dismounting and mounting part of heat preservation roller devices are saved, and the time for workers to work in dangerous areas is shortened.

Description

technical field [0001] The invention relates to a trolley for transporting mechanical devices, in particular to a simple trolley for hoisting insulation rollers and its usage method. Background technique [0002] The thermal insulation roller device of the high-speed wire rod and rod wire unit is mainly composed of a motor, a coupling, a thermal insulation roller, an end cover and a base. The common way to disassemble and install the insulation roller device is to use the combination of driving and chain hoists. However, some insulating roller devices and other devices are located in poor locations, and they cannot be hoisted directly by driving. We can only weld lifting lugs on the beams at the viewing platform, using steel wire ropes and chain hoists to cooperate. Increased safety hazards, extended maintenance time, and need to invest a lot of manpower and equipment resources for maintenance. [0003] Therefore known dismounting, the method for installing rolling line in...
