An upper positioning device for an auxiliary welding device of a hoist

Abstract

The invention discloses an upper-portion positioning device for an auxiliary welding device of an elevator. The upper-portion positioning device comprises a fixing frame. The rear end of the fixing frame is symmetrically provided with sliding blocks in a left-right manner. The lower end of the fixing frame is fixedly provided with a positioning plate. The front end of the positioning plate is provided with a blocking edge. Side plates are fixedly hinged to the left end and the right end of the positioning plate respectively. The lower ends of the side plates are provided with limiting strips. Hydraulic cylinders are hinged to the outer sides of the side plates. The other ends of the hydraulic cylinders are hinged to the positioning plate. A baffle is arranged at the rear end of the positioning plate. Multiple lifting air cylinders are arranged at the upper end of the positioning plate. L-shaped connection blocks are fixed to the top ends of the lifting air cylinders respectively and connected with the baffle. The upper-portion positioning device has the beneficial effects that the device is reasonable in structural design, low in manufacturing cost, convenient to use and the like; the side plates and the limiting strips are designed, precise positioning of rectangular flanges is achieved, welding efficiency is guaranteed, and product quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of hoist equipment, in particular to an upper positioning device for an auxiliary welding device of a hoist. Background technique [0002] The hoist is an important equipment in mine mining. It is used for the transportation of minerals. Its performance is very important to the safe production of the mine, and the shell of the mine hoist requires good sealing. In the production of hoist shells in our country, manual welding is basically adopted, so the precision of the products is not very good, and the quality is also uneven. Therefore, there is an urgent need for a welding auxiliary device for positioning the rectangular flange of the hoist shell on the market. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides an upper positioning device for an auxiliary welding device of a hoist. [0004] The present invention solves its technical problem ...
