Handheld bolt rust removal device

Abstract

The invention discloses a handheld bolt rust removal device, and belongs to the technical field of bolt repair. The handheld bolt rust removal device comprises a handle, a metal rod, a bearing, a bevel gear meshing device, a screw rod with an external thread, a spiral wire, a metal shell and a bolt fixing device, wherein the handle is fixedly connected with the metal rod; the metal rod is in interference fit with the bearing; and internal threads are arranged on the portions, making contact with the screw rod, of bevel gears; triangular metal barbs are arranged on the spiral wire; the metal shell and the bolt fixing device are connected through a bolt; and the bolt fixing device adjusts clamps on the two sides through forward and reverse lead screws. Due to the arrangement of a handle connecting device, the force application direction of a worker during rust removal is changed; due to the arrangement of the bevel gears, acting is more labor-saving, operation is convenient, and the rustremoval efficiency is improved; the bevel gears are different in size, and the handle is rocked to enable the spiral wire to evenly and slowly move downwards spirally, so that rust removal of the bolt is cleaner, and the rust removal quality is improved; the bolt fixing device is controlled by the positive and negative lead screws, so that the clamps on the two sides are opened and closed simultaneously, the bolt is located in the center of the rust removal device, and rust removal is more accurate; and through the arrangement of the metal shell, iron rust can be prevented from splashing during rust removal of the bolt, and environmental pollution can be reduced.

Description

technical field [0001] The invention belongs to the technical field of bolt repair, and in particular relates to a hand-held bolt derusting device. Background technique [0002] For the construction of ultra-long, ultra-wide, and large-span prefabricated steel structure industrial plants, the structural connections are complex and require high precision. The steel structural components processed in sections require a large number of bolts to be fixed in factory prefabricated assembly and installation on the construction site. Some bolts After repeated use and exposure to wind and sun, rust will occur, affecting the use of bolts. The existing semi-automatic derusting equipment needs to be connected to a power supply, and the equipment is too large to be placed anywhere, so it is necessary to develop an easy-to-operate and easy-to-carry bolt derusting equipment. Contents of the invention [0003] The purpose of the present invention is to provide a hand-held bolt derusting ...
