The guiding and limiting structure of the trolley used for prefabricated track beams, and the prefabricated mold

Abstract

The invention discloses a guide limiting structure of a trolley used for prefabricating a rail beam and a prefabricating mould provided with the guide limiting structure and used for the rail beam. The guide limiting structure comprises a guide limiting claw, a guide limiting base and a limiting plate, wherein the guide limiting claw is suitable for being arranged on the end surface of the trolley; a guide wheel is arranged on the guide limiting claw; the guide limiting base is suitable for being fixed on a predetermined position of ground; a guide slot is formed in the guide limiting base; when the guide limiting claw extends into the guide slot, the guide wheel is in contact with the inner peripheral wall of the guide slot; the limiting plate can be rotatably arranged on the guide limiting base between an avoiding position and a fixed position; at the fixed position, the limiting plate is positioned at one side of the guide limiting claw for blocking the guide limiting claw, and the limiting plate is fixedly arranged on the guide limiting claw; and at the avoiding position, the limiting plate is taken in the guide limiting base. According to the guide limiting structure disclosed by the invention, travelling of the trolley is guided, so that the trolley is prevented from offsetting, and therefore, the trolley can be fixedly arranged on the predetermined position of the ground, and the trolley is prevented from an unstable parking phenomenon.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a guiding and limiting structure for a trolley of a prefabricated rail beam and a prefabricated mold of the rail beam provided therewith. Background technique [0002] The straddle rail transit system consists of three parts: car body, bogie assembly and single track beam. The bogie assembly is fitted on the single track beam and connected with the car body. The bogie assembly is driven by its own electric The track beams move and pull the car body forward. [0003] At present, the single track beam is processed and formed by using prefabricated molds. The existing prefabricated molds include two rows of columns, two formworks and trolleys. The two formworks can move relative to each other to define the width of the single track beam. Steel bars are erected on the trolley. During the prefabrication process of the track beam, the trolley travels between the two formwo...

Problems solved by technology

[0004] The method of positioning the trolley in the related art is to place points on the trolley and the predetermined reference object separately. When the trolley is moving, the artificial naked eye judges that the trolley is moving in place by judging that the two points are aligned. The accuracy is low and it is prone to deviation.
