Nonlinear joist steel rail cable traction device

Abstract

The invention relates to a cable traction device, and belongs to the technical field of logistics equipment. The cable traction device comprises a traction car, traction car rails and the like; the traction car rails are nonlinear joist steel rails; the traction car comprises one towing car, multiple middle cars and one fixed tail car; the towing car and the middle cars and the middle cars are connected through traction accessories; and walking wheels of the traction car are arranged as arcs, and the radians and the treads thereof are matched with the traction car rails. The cable traction device is additionally provided with tipping prevention devices and support plates fixed on two sides of the traction car; the tipping prevention devices are arranged on upper and lower layers; four upper tipping prevention wheels are arranged on the upper layer; two upper tipping prevention wheels are on the left side, and the other two upper tipping prevention wheels are on the right side; the upper tipping prevention wheels are fixed on fixed plates; the lower ends of the fixed plates are respectively fixed with the support plates on two sides of a car body of the traction car; four lower tipping prevention wheels are arranged on the lower layer of the tipping prevention devices; two lower tipping prevention wheels are on the left side, and the other two lower tipping prevention wheels are on the right side; and the lower tipping prevention wheels are contacted with the lower planes of the traction car rails.

Description

technical field [0001] The invention relates to the technical field of logistics equipment, in particular to a cable trolley device. Background technique [0002] At present, most of the cable drag devices on domestic large-scale loading and unloading machinery are mainly linear tracks, or a small number of circular or spiral tracks. The tracks mainly include I-beams and square tubes. It is arranged in a straight line, and its running track is only suitable for a straight track. Especially when the trolley track is a curve with a constantly changing radius, when the trolley moves along the track at a constant speed, it will tip over under the action of centripetal force and cannot move normally and smoothly. Contents of the invention [0003] The object of the present invention is to design a non-linear I-shaped steel track cable trolley device in order to overcome the above-mentioned defects in the prior art. [0004] The present invention can be realized through the fo...
