Problems solved by technology

When using friction sliding, it is difficult to ensure the sliding surface due to the open-air environment
At the same time, it is not suitable to adopt the mature wheel group form, because the huge wheel pressure has strict requirements on the pile foundation of the civil foundation, which is unreasonable technically and economically.

Abstract

An active-type roller vehicle comprises an active chain wheel and a guiding wheel which are connected through a roller chain. The active chain wheel is connected with a gear motor through a transmission shaft, the roller chain comprises rollers and roller pins, the roller pins are connected with the rollers through holes formed in the two ends of the roller pins, and the rollers are connected intothe annular roller chain in series through the roller pins. According to the active-type roller wheel, the gear motor drives the active chain wheel to drive the roller chain to move along a fixed path, so that a large heavy load component is driven. The roller vehicle chain wheel adopts the upper-arranged mode, only bears torque and does not bear a radial load, the life of a driving device is effectively prolonged, and thus the roller vehicle chain wheel is specially suitable for the occasion that a cart operation mechanism needs to bear an over-weight load, but the structural arrangement space is small, and the size is limited; and the gear motor driving device is applied to a roller vehicle bearing structure to enable the roller vehicle bearing structure to become the active-type rollervehicle, and a driving mechanism special for driving a crane cart to operate does not need to be arranged any longer.

Description

technical field [0001] The invention relates to a super-large gantry crane, in particular to an active roller car. Background technique [0002] With the continuous development of industrial technology, there are more and more demands for hoisting and loading super-large metal structures. At present, the domestic super-large bridge and gantry cranes "Taishan" and "Honghai" have become the cranes with the largest lifting weight in the field of lifting. The operating mechanisms of these two cranes are divided into support system, drive system and control system, and the support system adopts rolling friction and sliding friction respectively. When friction sliding is used, it is difficult to ensure the sliding surface due to the open-air environment. At the same time, it is not suitable to adopt the mature wheel group form, because the huge wheel pressure has strict requirements on the pile foundation of the civil foundation, which is unreasonable technically and economically...
