Automatic steel rail shifting and feeding mechanism and method

Abstract

The invention provides an automatic steel rail shifting and feeding mechanism and method. The method comprises the following steps: S1, calculating the number of trolleys; S2, sensing the position ofa steel rail; S3, entering the position under the steel rail; S4, enabling the trolleys to jack up a lifting platform so that the steel rail is separated from a material frame plane; S5, moving the steel rail to a working roller way; S6, enabling the trolleys to fall back; and S7, repeating the steps S1 to S6, and conducting circulation in this way till automatic shifting and feeding of all the steel rails are completed. The number of trolleys can be automatically calculated, steel rails can be automatically found, lifted and straightened, steel rail shifting and inclined or zero-clearance steel rail placement can be automatically and accurately completed, and the mechanism is not affected in shifting and feeding.

Description

technical field [0001] The invention belongs to the technical field of rail transportation for operation transportation, and in particular relates to an automatic distribution and feeding mechanism for rails and a method thereof. Background technique [0002] During the production and manufacture of turnout rails, in order to facilitate the operation of workers and improve production efficiency, the processing machine tools will be equipped with special rail loading platforms. Rail loading platform (see figure 1 ) is mainly composed of a working roller table 1, a multi-group material rack 2 and a rail distribution feeding mechanism 3. Wherein, the rack 2 is mainly used to bear the weight of the rail. The rail distribution and feeding mechanism 3 is a chain transmission mechanism with a push block 4: (such as figure 2 , image 3 Shown) rail distribution feeding mechanism 3 is made up of push block 4, chain 5, block 6, bearing pin 7, roller 8. It is used to control the s...

Problems solved by technology

It can be seen that the problems in this traditional structure are: (1) In order to ensure that the push block 4 smoothly enters the material side of the rail, a certain width must be reserved between the rails, which must be greater than the width of the push block. The distance between the original positions is small or they are in contact with each other. Manpower and auxiliary tools such as cranes are required to separate the rails, and the rails must be placed in parallel. The process is cumbersome, labor-intensive, time-consuming, and labor-intensive.

(2) The chain transmission mechanism adopts the overall brake synchronous movement mode. The moving positions of the push blocks of different racks are the same, and the rails must be placed in parallel and spaced apart. If the rails on the rack are tilted, the chain push blocks will stop at the push side of different rails at the same time. Unable to complete single rail pushing correctly, an error occurs
