Description

Technical Field

[0001] The utility model relates to the field of equipment for producing concrete sleepers, in particular to a general vibration platform for producing concrete sleepers. Background Art

[0002] Concrete sleepers are a type of sleeper commonly used in track construction. They have excellent performance. The main production method is to use a built mold, then put the tied steel bars in the template, and then pour the concrete, and finally demold and maintain it. When using the mold for pouring, it is also necessary to expel the gas in the concrete fluid through vibration, which can improve the quality of the produced products. To complete the above operations, the mold poured with concrete is generally placed on a general vibration platform for vibration.

[0003] The existing general vibration platform has a simple structure, which is generally composed of a table and a vibration motor. The defects of this structure are very obvious. The main one is that during the vibration process, the mold will move due to the vibration. Therefore, the entire processing process needs to be stopped to adjust the position to prevent the mold from falling, which greatly prolongs the processing time. In addition, the mold filled with cement is usually heavy, and it is difficult for the operator to adjust the position. There are also solutions to this problem in the prior art. Specifically, the solution disclosed in the utility model with application number "CN202321960488.3" can be seen. It mainly solves this problem by setting a limiting plate, but it also has certain defects. As can be seen from the above solution, the limiting plate of this solution only plays a limiting role and cannot bring pressure to the mold. Therefore, although it cannot move to the sides, it can move forward and backward, which will affect the guide rail of the limiting plate, and because it can still move, it is noisy. Utility Model Content

[0004] The utility model aims to provide a general vibration platform for producing concrete sleepers, so as to solve the problem that the general vibration platform for producing existing concrete sleepers cannot effectively restrict the movement of the mold on the table.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A general vibration platform for producing concrete sleepers comprises a vibration platform and a vibration motor, wherein the vibration motor is arranged at the bottom of the vibration platform, the top surface of the vibration platform is provided with a clamping limit device, the clamping limit device comprises a slide rail, a side pressure plate and a top pressure mechanism, the slide rails are opened on both sides of the top surface of the vibration platform, the slide rails are parallel to the short sides of the vibration platform, the two sides of the bottom of the side pressure plate are provided with a clamping slider, the clamping slider is slidably clamped in the slide rail, the outer side of the side pressure plate is provided with a push rod, the middle part of the push rod is threadedly connected with a fixed plate arranged on the outer side of the side pressure plate, the outer end of the push rod is provided with a push rod screwing block, and the top pressure mechanism is arranged at the upper part of the inner side of the side pressure plate.

[0007] In this solution, a push rod is provided at the outer end of the side pressure plate. After the mold is placed on the top surface of the vibration platform, the push rod is used to push the side pressure plate to both sides of the mold. The push rod and the side pressure plate are rotatably connected. When the side pressure plate presses the mold, the top pressure mechanism is used to press the top of the mold. In this way, the friction between the side pressure plate and the mold, and the friction between the mold and the vibration platform can be well utilized to position the mold, so that the mold will not move during the vibration process. This not only reduces noise, but also does not require the mold position to be adjusted during the processing process, which is more efficient. In addition, there is no guide rail in this solution, only a slide rail, and the slide rail is a concave slide rail, so it will not be affected, which solves the problems in the prior art.

[0008] As a further preferred embodiment of the present invention, the vibration platform includes a table panel, a spring connection structure and a base which are arranged in sequence from top to bottom, and the base is fixed to the ground by bolts.

[0009] As a further preferred embodiment of the present invention, a rubber sound-absorbing pad is provided between the base and the ground.

[0010] Less noise.

[0011] As a further preferred embodiment of the utility model, the pressing mechanism includes a pressing cross bar, the middle of which is evenly provided with threaded through holes, the threaded through holes are all provided with vertical threaded rods, and the top of the vertical threaded rod is provided with a vertical threaded rod screwing block.

[0012] The mold can be pressed down and loosened by rotating the vertical threaded rod, and the structure is simple.

[0013] As a further preferred embodiment of the present invention, a rubber sound-absorbing pad is provided at the bottom of the vertical threaded rod.

[0014] Less noise.

[0015] As a further preferred embodiment of the present invention, a rubber sound-absorbing pad is also provided on the inner side of the side pressure plate.

[0016] Further reduce noise.

[0017] Compared with the prior art, the utility model can achieve at least one of the following beneficial effects:

[0018] 1. In this scheme, a push rod is set at the outer end of the side pressure plate. After the mold is placed on the top surface of the vibration platform, the push rod is used to push the side pressure plate to both sides of the mold. The push rod and the side pressure plate are rotatably connected. When the side pressure plate presses the mold, the top pressure mechanism is used to press the top of the mold. In this way, the friction between the side pressure plate and the mold, and the friction between the mold and the vibration platform can be well utilized to position the mold, so that the mold will not move during the vibration process. This not only reduces noise, but also does not need to adjust the mold position during processing, which is more efficient.

[0019] 2. Less noise.

[0020] 3. The mold can be pressed down and loosened by rotating the vertical threaded rod, and the structure is simple. BRIEF DESCRIPTION OF THE DRAWINGS
