Turnout rim-free vehicle wheel track-changing mechanism and track-changing method thereof

Abstract

The invention provides a turnout rim-free vehicle wheel track-changing mechanism and a track-changing method thereof. The turnout rim-free vehicle wheel track-changing mechanism comprises a linear guide rail, a turnout guide rail, an arc direction-diving guide rail and a rim-free vehicle wheel shelf, the arc direction-diving guide rail is arranged between the linear guide rail and the turnout guide rail, guiding wheel limiting mechanisms are arranged on both the linear guide rail and the turnout guide rail, and a left marching mechanism and a right marching mechanism which are of the same structure are arranged at the two sides of the bottom of the rim-free vehicle wheel shelf respectively; the left marching mechanism comprises a front left guiding wheel, a rear left guiding wheel and a left electro-controlled electric cylinder; the right marching mechanism comprises a front right guiding wheel, a rear right guiding wheel and a right electro-controlled electric cylinder. According to the turnout rim-free vehicle wheel track-changing mechanism and the track-changing method thereof, by controlling rising and falling of the front guiding wheel and the right guiding wheel, the track-changing motion of the device is achieved, track changing is steadily conducted, the turnout rim-free vehicle wheel track-changing mechanism is convenient to install and east to control, the arrangement space of the equipment in a dense-type rail traffic is better saved, and the economic benefit is obvious.

Description

technical field [0001] The invention relates to the technical field of track-changing mechanisms, in particular to a track-changing mechanism and a track-changing method for a rimless wheel at a turnout. Background technique [0002] In the field of warehousing and logistics, stackers are usually used to store and retrieve goods in dense warehouses, and most of the stackers are tracked roadway stackers. With the improvement of the efficiency of the stacker and the requirement of saving costs, a few rail stackers will be arranged in multiple lanes of dense warehouses, so that they can shuttle back and forth between the lanes to store and retrieve goods. In order to realize the shuttle work of the track stacker between the roadways, the structural form of the track switch is usually used, and the driving route of the track stacker is changed by changing the docked track. There are some disadvantages in the existing turnout structure: First, the turnout needs to be moved to re...

Problems solved by technology

There are some disadvantages in the existing turnout structure: First, the turnout needs to be moved to realize the conversion of the track. During the switch conversion process, if the turnout is not moved, it is easy to derail the passing stacker and cause an accident; If the turnout is moved in the wrong direction, it will cause the stacker to enter the wrong roadway; secondly, the stacker runs poorly when passing the turnout, and there is a gap at the joint of the track, and the stacker will jump, which is harmful to the stacker. The turnout and its cargo will cause damage; in addition, the installation of the turnout structure is cumbersome, the control is complicated, and it is not easy to troubleshoot after a fault occurs.
