Special tool for hoisting of coal feeder

Abstract

The invention discloses a special tool for hoisting of a coal feeder. The special tool comprises a trimmer (A) and is characterized in that lifting lugs (B) are welded at the upper parts of two ends of the trimmer (A), and two clamping devices (C) are fixedly arranged on the upper surface of the middle part of the trimmer (A); the distance between the two clamping devices (C) is matched with the width of the coal feeder. Compared with the prior art, the special tool is convenient to use and simple to operate; a flexible-connection hoisting process in the prior art is improved as rigid-connection hoisting, so that hoisting operation is relatively safe, the working efficiency is doubled, and the special tool has favorable popularization prospect.

Description

technical field [0001] The invention relates to a hoisting tool, in particular to a special tool for hoisting a coal feeder. Background technique [0002] As we all know, the installation position of the vibrating coal feeder is generally relatively high, and the hoisting conditions on site are relatively poor, which greatly restricts the hoisting operation during the installation of the coal feeder, directly restricting the installation progress of the equipment. At present, when installing the coal feeder, it is generally directly tied with rigging or welded on the equipment with lifting lugs. Since the lower plane of the coal feeder has a certain angle, using slings to directly bind the slings for hoisting will cause the slings to slip, which will wear the slings if it is light, and will cause the center of gravity of the equipment to shift and tip over if it is heavy, so the operation is safe. It cannot be guaranteed; and the angle of the coal feeder cannot be adjusted ...

AI Technical Summary

Problems solved by technology

Since the lower plane of the coal feeder has a certain angle, using slings to directly bind the slings for hoisting will cause the slings to slip, which will wear the slings if it is light, and will cause the center of gravity of the equipment to shift and tip over if it is heavy, so the operation is safe. It cannot be guaranteed; and the angle of the coal feeder cannot be adjusted during the hoisting process, which will bring great difficulties to the equipment in place and greatly reduce the installation efficiency of the equipment

The coal feeder is hoisted by welding the lifting lugs on the coal feeder. First, welding and removing the lifting lugs will increase the workload of the coal feeder installation; second, the coal feeder is a vibrating device, and welding the lifting lugs on the coal feeder will cause stress concentration. The operation of the coal feeder will cause many disadvantages, and at the same time, it will damage the anti-corrosion layer of the coal feeder, seriously affecting the appearance quality of the equipment

The third is that the material of the inner lining plate of the coal feeder is generally manganese steel plate or stainless steel plate. It is not easy to master the matching of the welding material when welding the lifting lug, which may easily cause the mismatch between the welding material and the base material, and the welding quality is not good. During the hoisting process of the machine, it is easy to pull the welding seam of the lifting lug to cause serious safety accidents
