Example Embodiment

[0014] From figure 1 , figure 2 The implementation of the present invention shown shows that after the side guide wheels 4 are pressed against the upper side of the rail 15, there is a slight gap between the wheel flange 14 and the rail side during the operation of the crane, and there is no friction between the wheel flange and the rail side. , Effectively prevent the phenomenon of wheel rim gnawing the rail.

[0015] To implement the force process, the side guide wheel 4 pushes against the side of the rail, passes through the bearing 2, the guide wheel shaft 1, and acts on the guide wheel frame 5, passes through the screw 9 to the screw hole block 6, to the blocking pin 7, and finally the force reaches On the chute combined boxes 10 and 11, the chute combined box is fixed to the lower part of the crane trolley through a steel structure 13.

[0016] The first advantage of the present invention is that when the proper positions of the side guide wheel 4 and the wheel rim 14 need t...

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 ...
