Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of production mould equipment, in particular to a production mould for railway track plates. Background Art
[0002] Track slabs refer to components located on the track for supporting and fixing the track and transferring loads. They are usually made of steel or concrete. They have high strength, corrosion resistance and durability and can withstand a large amount of heavy loads and dynamic loads.
[0003] High-speed railways are generally divided into two types: ballasted track and ballastless track. Ballastless track refers to a track structure that uses an integral foundation such as concrete and asphalt mixture to replace the granular gravel roadbed. Compared with ballasted track, ballastless track avoids ballast splashing, has good smoothness and stability, long service life, good durability and less maintenance work, allowing trains to run at speeds of more than 350 kilometers per hour.
[0004] Ballastless track slabs are generally processed and produced in factories and then transported to the construction site for assembly. During the track slab production process, the steel cage is hoisted into the mold station and hoisted into the mold to be operated. After the steel frame is put into the mold, the tension rod needs to be connected to the corresponding prestressed steel wire, and the prestressed steel wire needs to be tightened to ensure the flatness of the prestressed steel wire. Multiple sets of tension rods need to be tightened one by one by the staff. Due to the large size of the track formwork, the work efficiency is reduced. Utility Model Content

[0011] By adopting the above technical solution, the lower end of the bevel gear is connected to a belt through a rotating shaft, so that the positioning plates at both ends of the steel frame are close to the steel frame at the same time.
[0012] The utility model is further configured that the outer walls of the positioning tube and the tension rod are both provided with through holes, and the through holes of the positioning tube and the tension rod overlap.

[0015] By adopting the above technical solution, the push rod in the electric push rod passes through the positioning tube and the through hole on the surface of the tension rod, which facilitates the separation of multiple groups of tension rods from the steel caps.
[0016] The utility model is further configured that the rotating rod is connected to a plurality of bevel gear groups, and a telescopic rod is provided at the middle end of the rotating rod, and the other end of the telescopic rod is fixedly connected to the positioning plate.
[0017] By adopting the above technical solution, the middle part of the positioning plate is effectively supported, and the rotating rod and the telescopic rod are connected through the bearing.
[0018] The utility model is further configured that the screw rod is movably sleeved on the inner wall of the bevel gear, a set of inner walls of the bevel gear are provided with threads, and the screw rod is threadedly connected with the bevel gear.
[0019] By adopting the above technical solution, the rotation of multiple sets of bevel gears causes the screw to rotate inside the bevel gears, thereby pushing the positioning plate at one end of the screw to move toward the direction of the steel bar skeleton.

Repeat the above steps. When it is necessary to pull the tension rod 47 out of the inner wall of the steel frame 3, first start the electric push rod 48 so that the push rod in the electric push rod 48 passes through the positioning cylinder 45 and the through hole on the surface of the tension rod 47, and the thrust of the positioning plate 44 moving backward separates the multiple groups of tension rods 47 from the steel cap.
[0046] Furthermore, when the tension rod 47 is sleeved on the inner wall of the steel cap, the inner wall of the steel cap is provided with a groove 53 corresponding to the limit block 52, and the two are engaged, so that the spring block 51 provides tension support for the two groups of limit blocks 52, so that the tension rod 47 is located on the inner wall of the steel cap and the steel cap limits the position of the tension rod 47, thereby improving the stability of the steel skeleton 3.
