Rack transmission type rail electric running trolley

Abstract

The invention discloses a rack transmission type rail electric running trolley, and belongs to the field of cranes. The rack transmission type rail electric running trolley comprises a first slide rail and a second slide rail, the right side of the first slide rail is fixedly connected to the left side of the second slide rail, and the top of the first slide rail is slidably connected with a transmission mechanism; vertical rails are fixedly connected to the left side of the first sliding rail and the right side of the second sliding rail, and a driving mechanism is slidably connected to a top support of the two vertical rails, the first sliding rail and the second sliding rail are combined into a bearing main body of the device, and the driving mechanism at the tops of the two vertical rails is started; the output end of the driving mechanism can drive the transmission mechanism to linearly slide along the top of the first sliding rail, the transmission mechanism drives a trolley body in the second sliding rail to synchronously move, and the trolley body moves in the second sliding rail, so that the device has the advantages that the operation is stable, impact abrasion is reduced, the service life of the device is prolonged, and the stroke of the trolley can be increased.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a rack-driven track electric running trolley. Background technique [0002] A crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range. [0003] The existing driving mode of the trolley in the track is often driven by the drive motor to directly drive the friction wheel to rotate on the track to realize the movement of the trolley. The operation is very unstable and the stability is poor under different load conditions. When braking and braking, the impact wear between the trolley and the track is very large, which directly leads to the reduction of the service life of the track and the trolley, and in the prior art, there is a part of the driving mode of the friction wheel with a gear and rack structure. This structure is used in The above situation has been improved to a certain extent, but the travel of the ca...

Problems solved by technology

[0004] Aiming at the problems existing in the prior art, the object of the present invention is to provide a rack-driven track electric running trolley, so as to solve the problem that the trolley in the prior art runs very unstable and has poor stability under different load conditions, and this driving mode When the trolley starts and brakes, the impact wear between the trolley and the track is very large, which directly leads to the problem of reducing the service life of the track and the trolley
