[0002] Tracks are important infrastructure in the railway system, and concrete sleepers are important components in the track structure, playing two major roles: transferring train loads and maintaining the stability of track geometric dimensions.

[0003] In the prior art, a mold is used to prefabricate concrete sleepers. Fixed hanging plates and lifting equipment are used at both ends of the mold for lifting. However, this structure requires a flipping machine for demoulding. When the mold is manually demoulded, the hook of the lifting equipment also flips when the mold is flipped. It takes more effort to flip the mold, which is difficult to flip. In addition, the hook is prone to entanglement after flipping. In addition, after the existing mold is flipped, the entire mold is inverted on the support surface. After the mold is lifted, it sometimes does not demould immediately. It will be demoulded after it is lifted to a certain height and cannot fall accurately on the support surface. Therefore, an improved technology is urgently needed to solve the above problems existing in the prior art. Utility Model Content

[0004] The purpose of the utility model is to provide a mold for the production of assembled concrete prefabricated sleepers. The steel mold table can be suitable for demoulding by a turning machine or for manual demoulding. When the mold is turned over and demoulded manually, the steel mold table rotates with the shaft rod as the center, while the hanging parts and the connecting sleeve parts will not rotate with it, thereby ensuring that the hook part of the lifting equipment will not turn over. Firstly, the labor intensity when turning over the steel mold table can be reduced, and secondly, the hook part of the lifting equipment can be prevented from being entangled when turning over the steel mold table. Demolding support legs are respectively arranged at the four corners of the upper surface of the steel mold table. After turning over, a certain space is left for better demoulding, thereby improving the accuracy of demoulding, thereby solving the problems raised in the above-mentioned background technology.

A hanging piece 8 is arranged at one end of the connecting sleeve 7. The hanging piece 8 is penetrated by a hanging hole 10. The hanging piece 8 is lifted in cooperation with the hook of the lifting equipment through the hanging hole 10. A demoulding support leg 9 is arranged at each of the four corners of the upper surface of the steel mold table 1. The horizontal height of the top of the demoulding support leg 9 is greater than the horizontal height of the upper surface of the steel mold table 1. When flipping and demoulding, the inverted steel mold table 1 can be propped up by the demoulding support leg 9, thereby reserving demoulding space and improving the demoulding effect. Handles 11 are symmetrically arranged on the outer walls on both sides of the steel mold table 1. By setting the handles 11, the flipping operation is convenient during manual demoulding.

[0021] Installation method and principle of use: The steel mold table 1 is a standardized steel mold with a certain wall thickness to ensure that it does not lose stability during the sleeper prefabrication process. The structural dimensions of the inner mold cavity 2 of the steel mold table 1 can be determined according to the sleeper structure type and sleeper structure dimensions. At the same time, the inner mold cavity 2 of the steel mold table 1 needs to be polished to ensure that the inner mold dimensions meet the side line requirements of the sleeper. The preset holes 3 are used to install fasteners. During the prefabrication process, the corresponding accessories need to be embedded in advance to reserve the specified design hole positions in the sleeper. The preset holes 3 can be determined according to the design dimensions. The hanging parts 8 are used for hoisting in the assembly line production process of the sleeper unit. The four-corner demoulding support legs 9 are used to support the steel mold table 1 during demoulding to facilitate the mold turning of the concrete prefabricated sleepers. Among them, the production process of the concrete prefabricated sleeper unit is as follows: ① Cleaning the mold: The steel model can be reused. After the previous cycle of construction is completed, the mold needs to be cleaned before the current cycle of construction, and then the release agent needs to be evenly sprayed; ② Placing steel bars and accessories; ③ Mixing and distributing concrete: After the steel bars and accessories are installed and checked, the concrete distributing machine is used to accurately dispose of the mold to be constructed; ④ Vibrating and cleaning the concrete: The vibration operation is achieved with the help of a vibration table. After the vibration is qualified, the lifting roller is opened to send the mold to the next process; ⑤ Maintenance: The automatic temperature-controlled steam maintenance method is adopted, and the specific operation is carried out in sequence according to the process of static stop → heating → constant temperature → cooling. ⑥ Demolding: a. Demolding by a turning machine: The hook of the lifting equipment cooperates with the hanging piece 8, and the mold is moved to the specified position by hoisting. The trolley transfers the mold so that it enters the turning machine for turning over the mold; or, b. Manual demolding: The hook of the lifting equipment cooperates with the hanging piece 8, and the mold is moved to the specified position by hoisting. Then, the steel mold table 1 is slowly turned over manually by the handle 11 to achieve demolding. ⑦Classification and palletizing.

[0022] The utility model has a simple and reasonable structure and does not lose stability during the prefabrication of the sleeper. Extension columns 4 are arranged at the upper positions of the two ends of the steel mold platform 1, and shaft rods 5 are arranged at the outer ends of the extension columns 4. Connecting sleeves 7 are arranged on the shaft rods 5, and hanging pieces 8 are arranged on the upper surfaces of the connecting sleeves 7. When the whole is lifted, since the extension columns 4 are located at the upper position of the steel mold platform 1, it will not automatically flip over. When the mold is manually flipped and demoulded, the steel mold platform 1 rotates with the shaft rod 5 as the center, and the hanging pieces 8 and the connecting sleeve 7 will not rotate with it, so as to ensure that the hook part of the lifting equipment will not flip over. First, the labor intensity when flipping the steel mold platform 1 is reduced, and second, when flipping the steel mold platform 1, the hook part of the lifting equipment can be avoided from being entangled. The steel mold platform 1 can be used for demoulding by a flipping machine, and can also be used for manual demoulding, and the flexibility and convenience of use are greatly improved; demoulding support legs 9 are respectively arranged at the four corners of the upper surface of the steel mold platform 1. After flipping, a certain space is left for better demoulding and improving the accuracy of demoulding.
