Description

Vibrating screen wedge block dismounting tool

Technical Field

The utility model relates to the technical field of vibrating screen equipment, in particular to a vibrating screen wedge block dismounting tool.

Background

The vibrating screen is widely applied in the coal washing industry, the screen mesh of the vibrating screen is an important component part, and the screen mesh needs to vibrate continuously during working so as to lead the materials falling on the screen mesh to jump, thereby achieving the effect of screening the materials, and the screen mesh needs to be reliably fixed and pressed with a screen box. At present, most vibrating screens with detachable screens are required to be provided with two side pressing plates on two side edges of the screen during installation, a wedge block frame is fixedly arranged on the side wall of a screen box, a wedge block is inserted between the side pressing plates and the wedge block frame, the width of the tail part of the wedge block is larger than that of the head part, the head part can be easily inserted into a gap between the wedge block frame and the side pressing plates, the width of the tail part is slightly larger than that of the gap between the wedge block frame and the side pressing plates, and the side pressing plates can be tightly pressed by knocking in the wedge block by using a hammer, so that the screen is fixed with the screen box; when the side pressure plate is disassembled, the wedge blocks are reversely knocked down, so that the side pressure plate can be loosened.

In order to ensure that the wedge block cannot fall off in the vibration process, elastic materials, generally polyurethane materials, are required to be adopted, the wedge block can generate certain deformation after being knocked into the wedge block frame, so that interference fit is generated between the wedge block and the wedge block seat, and the anti-loosening effect can be realized; and when the hammer is repeatedly used for knocking during disassembly and assembly, the wedge block is possibly damaged and cracked, and because the position of the wedge block is tightly clung to the side wall of the vibrating screen, the wedge block is thinner, the operation space is narrow, the manual knocking operation is inconvenient, and the wedge block frame can be knocked to bend the wedge block frame, so that the wedge block frame is damaged.
