Rotary electromagnetic suspension bridge type crane

Abstract

The invention discloses a rotary electromagnetic suspension bridge type crane. The rotary electromagnetic suspension bridge type crane comprises a bridge, wherein the bridge comprises a left bridge and a right bridge; the left bridge is connected with the right bridge through a beam; travelling motors are arranged on the lower parts of the two ends of the beam; the travelling motors are connectedwith travelling wheels; a dirt cleaning device is arranged at one side of each travelling wheel; rails are arranged at the upper ends of the bridges; a trolley capable of moving along the rails in a parallel mode is arranged on the rails; trolley motors are arranged at the lower ends of four corners of the trolley; the trolley motors are connected with trolley roller wheels; a lifting device is arranged at the upper end of the trolley; the two sides of the bridge are connected with a platform through fixed supporting legs; a plurality of groups of electrical appliance control boxes are arranged on the platform, and guard bars are arranged at outer sides of the platform; the bridge is connected with a cab through ladders; and the upper end of the cab is welded to one end of the bottom of the bridge. The rotary electromagnetic suspension bridge type crane is reasonable in structural design, can effectively adsorb iron materials such as a steel plate, greatly improves working efficiency,and is safe and stable.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a rotating electromagnetic suspension bridge crane. Background technique [0002] The bridge crane is a lifting device that is horizontally placed over the workshop, warehouse and stockyard for material lifting. Because its two ends are located on tall concrete pillars or metal supports, it is shaped like a bridge. The bridge frame of the bridge crane runs longitudinally along the rails laid on the elevated sides on both sides. It can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. It is the most widely used and the largest number of hoisting machinery . Generally, the structure of the crane is relatively complicated and simple, the production efficiency is low, and the maintenance is not easy. In addition, due to long-term use, a large amount of oil and dust are easy to accumulate on the surface of the wheel. If it...

Problems solved by technology

Generally, the structure of the crane is relatively complex and single, the production efficiency is low, and the maintenance is not easy. In addition, due to long-term use, a large amount of oil and dust are easy to accumulate on the surface of the wheel. If it is not cleaned in time, the running state of the wheel will be affected.
