Problems solved by technology

These phenomena will cause sliding friction between the wheel rim and the side of the rail. When the friction pressure unit value is greater than the shear strength of the metal, the phenomenon of rail gnawing will occur, forming the phenomenon of metal cutting between the inner side of the wheel rim and the side of the rail. Over time, the wall of the rim becomes thinner and the side of the rail wears away

Embodiment Construction

[0014] From figure 1 , figure 2 As can be seen from the implementation of the present invention shown, after the side guide wheel 4 bears on the upper side of the rail 15, there is a small gap between the wheel flange 14 and the side of the rail during operation of the crane, and there is no friction between the wheel flange and the side of the rail. , Effectively prevent the wheel rim from gnawing on the rail.

[0015] The force process is implemented, the side guide wheel 4 bears against the side of the rail, through the bearing 2, the guide wheel shaft 1, acts on the guide wheel frame 5, passes through the screw 9 to the screw hole stopper 6, and transmits to the blocking pin 7, and finally the force reaches On the chute combination box 10,11, the chute combination box is fixed on the bottom of the crane trolley by the steel structure 13.

[0016] The first advantage of the present invention is that when it is necessary to adjust the proper position of the side guide whe...

Abstract

The invention relates to a side guide wheel assembly of bridge type and gantry type cranes for preventing the track biting of a rim. The side guide wheel assembly comprises a side guide wheel (4), a bearing (2), a guide wheel shaft (1) and a guide wheel frame (5). In box-shaped slide slots (10) (11), the acting position of the side guide wheel of the assembly is regulated by a screw rod (9) so as to ensure that a minute gap is reserved between a crane rim (14) and the side face of a steel wheel to prevent that the rim has contacts and frictions with the side face of a steel track and thoroughly avoid a phenomenon that the rim bites the side face of the steel track.

Description

technical field [0001] The invention relates to a side guide wheel assembly for preventing wheel rims from nibbling rails for bridge and gantry cranes. It includes a side guide wheel, a bearing, a guide wheel shaft, and a guide wheel frame to form an assembly. The assembly is in the box-shaped chute, and the side guide wheel is adjusted to the appropriate position by the screw, so that there is a slight gap between the wheel flange of the crane and the side of the rail, preventing the contact and friction between the wheel flange and the side of the rail, and completely avoiding the phenomenon that the wheel flange gnaws on the side of the rail . Background technique [0002] At present, the crane wheels walk on the rails, and the lateral control of the position of the wheel tread and the rail surface depends on the sliding friction force between the wheel flanges on both sides of the wheel tread and the side of the rail. In severe cases, rail gnawing occurs. [0003] The ...
