Abstract

The invention relates to a double-beam walking trolley, comprising a square frame body, a driving shaft and a driven shaft which can be rotatably penetrated in the square frame body, driving wheels located on the outer side of the square frame body and fixed at the two ends of the driving shaft, and a motor installed in the square frame body, wherein the driving shaft and the driven shaft are mutually parallel and form a horizontal plane, the motor is engaged with one driving wheel, columnar projections are integrally fixed at the two ends of the driven shaft, the columnar projections are located on the outer side of the square frame body, the driven wheel is installed on the columnar projections, and the axle wire of the driven shaft and the axle wires of the columnar projections at the two ends of the driven shaft are mutually parallel and are not located on the same straight line. Since the axle wire of the driven shaft and the axle wires of the columnar projections at the two ends of the driven shaft are mutually parallel and are not located on the same straight line, the three-leg phenomenon generated when the walking trolley walks on double beams is overcome, the non-uniform stress condition of the walking trolley is avoided and the service life of the walking trolley is prolonged.

Description

technical field

[0001] The invention belongs to the technical field of cranes, and in particular relates to a double-girder traveling trolley. Background technique

[0002] Cranes (also known as cranes) refer to multi-action hoisting machinery that vertically lifts and horizontally transports heavy objects within a certain range. It is used for material handling and can be divided into light and small lifting equipment, bridge type (bridge type, door type) type crane), jib type (self-propelled, tower type, portal type, railway type, pontoon type, mast type crane), cable type, etc. Among them, bridge cranes can work on rectangular sites and above them, and are mostly used for loading and unloading items in workshops, warehouses, open storage yards, etc. Beam cranes mainly include single-girder bridge cranes and double-girder bridge cranes. The advantage of the double-girder bridge crane is that it has a wide lifting range and can lift items ranging from 1 ton to 100 tons. ...
