Tower type rail-mounted portal hanging frame

Abstract

The invention discloses a tower type rail-mounted portal hanging frame. The tower type rail-mounted portal hanging frame comprises two bases which are arranged in parallel and supporting columns which are arranged on the bases. A hanging beam is horizontally arranged on the supporting columns. First grooves are formed inwards in the two sides of each supporting column respectively. The supporting columns are arranged in a vertically through mode. Two corresponding side faces of the interior of each supporting column are each vertically provided with a sliding groove. Each sliding groove and the corresponding first groove are located in two adjacent sides. Square pipes which can move along with the sliding grooves are connected to the sliding grooves. A plurality of limiting holes are horizontally formed in the upper side faces of the two first grooves of each supporting column at equal intervals. Limiting grooves are formed in the two sides of each square pipe respectively. A limiting rod is arranged in one limiting hole of each first groove. The square pipes are welded to the hanging beam. The two supporting columns each comprise a reinforcing part located in the middle and connecting parts located on the upper side and the lower side of the reinforcing part. The sliding grooves and the square pipes are arranged in the connecting parts on the upper portions. Each reinforcing part comprises a plurality of tower-shaped connecting blocks which are vertically connected. A pair of fixing pieces extends out from the lower portion of each base. A directional wheel is arranged between the fixing pieces extending out from the lower portion of each base. A rail matched with the directional wheels is arranged below the directional wheels.

Description

technical field [0001] The invention relates to a door-shaped hanger, in particular to a tower-shaped track-type door-shaped hanger. Background technique [0002] The portal hanger is a new type of small lifting gantry developed according to the daily production needs of medium and small factories (companies) for handling equipment, warehouse import and export, lifting and maintenance of heavy equipment and material transportation. It is suitable for making molds, auto repair factories, mines, civil construction sites and occasions that require lifting. It is commonly used in building construction as material transportation and construction personnel's upper and lower use to realize lifting mechanization. It can reduce manpower, reduce production and operation costs, and improve work efficiency. Most of the existing door-shaped hangers are fixed in height and size. They cannot flexibly realize their functions in some small workshops, and are restricted everywhere, restrict...

AI Technical Summary

Problems solved by technology

Most of the existing door-shaped hangers are fixed in height and size. They cannot flexibly realize their functions in some small workshops, and are restricted everywhere, restricting the flow of products and affecting the handling efficiency. Moreover, the current door industry Due to the long-term use of the hanger or the heavy load, the supporting columns on both sides will accelerate aging and breakage, which will affect its service life
