Wheel pressure balance mechanism for crane cab

Abstract

The invention discloses a wheel pressure balance mechanism for a crane cab. The wheel pressure balance mechanism comprises a plurality of wheel group fixing seats, a balance rod fixing seat, a first balance rod and a plurality of wheel groups, wherein the wheel group fixing seats are arranged above the crane cab and correspond to a guide rail group; the guide rail group comprises a first guide rail and a second guide rail; the first guide rail is parallel to the second guide rail; the balance rod fixing seat is arranged above the crane cab; the center of the first balance rod is movably connected to the balance rod fixing seat; each wheel group is provided with at least one wheel; all the wheel groups are respectively arranged on all the wheel group fixing seats and at the two ends of the first balance rod; the crane cab is suspended on the guide rail group through the wheel groups and is driven by at least one driving motor to move below a crane main beam; the wheel group fixing seats and the balance rod fixing seat are arranged on one plane, and the first balance rod is movably connected to the balance rod fixing seat. According to the wheel pressure balance mechanism, the phenomena that the known guide rail group is easily deformed, the wheel groups and the guide rail group are rapider in abrasion, the crane cab often cannot get power instantly and cannot move smoothly to generate unpleasant noise can be avoided.

Description

technical field [0001] The invention relates to a balance mechanism, in particular to a wheel pressure balance mechanism of a crane cab. Background technique [0002] When the commonly used cranes are in use, since three points determine a common plane, in the worst case, three sets of wheel sets bear the weight of the crane cab, resulting in excessive wheel pressure, which makes the guide rail set easy to deform or the wheel set and The wear of the rail set is faster. In addition, if the wheel set does not touch the guide rail set when moving, it will cause the lifting cab to have no power and the movement is not smooth, and produce unpleasant noises. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a wheel pressure balance mechanism for a crane cab. [0004] The technical solution adopted to solve the above technical problems is: a wheel pressure balance mechanism of a...
