Crane track change and docking device

Abstract

The invention discloses a rail changing butt joint device for crane rails. The rail changing butt joint device comprises the first butt joint sliding rail and the second butt joint sliding rail which are in butt joint. A positioning groove plate is fixed to the first butt joint sliding rail, and a positioning groove is formed in the positioning groove plate. Correspondingly, a positioning plate inserted in the positioning groove is arranged on the second butt joint sliding rail. The positioning plate is connected with one end of a manual driving lever so as to be rotationally arranged on a supporting pillar above the second butt joint sliding rail. According to the rail changing butt joint device for the crane rails, due to rail conversion, the same crane device can work in different stations, on and off of the molded rails can be convenient, the cost of matched equipment of a user is reduced, limiting blocks are arranged on all butt joint connector devices respectively, and a trolley not in a butt joint state on the rails is prevented from sliding out of the rails. In addition, due to the design of the butt joint device, the manual accurate positioning plate is designed and the positioning groove matched with the accurate positioning plate is designed, double-rail accurate positioning butt joint is achieved, the rails do not interference with each other after being butt joint on and off, and therefore a set of lifting equipment can be used for every two adjacent stations.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a rail switching and docking device for a crane. Background technique [0002] The trolley track of the crane must be fixed on the travel beam, and the trolley track must be fixed on the main beam. When the crane is running, the track cannot move horizontally and vertically, and the track should be easy to adjust. During the use of conventional lifting equipment, due to the limitation of the track structure, the lifting equipment can only be used within a limited working range. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a docking device that is convenient for rapid on-off of rails, and is especially suitable for a crane rail-changing docking device for a suspension and hoisting equipment system. [0004] The technical solution adopted by the present invention in order to solve the technical problem is: a c...
