Description

Technical Field

[0001] This utility model relates to the field of building material molding mold technology, specifically a concrete sleeper production mold. Background Technology

[0002] In railway track construction, concrete sleepers are key components that support the rails and transmit train loads. As a crucial foundational component that supports the rails, transmits train loads, and maintains the geometric stability of the track, the production efficiency of concrete sleepers not only directly affects the construction progress and paving continuity of track engineering, but is also closely related to the timely commissioning of railway lines.

[0003] During equipment use, the heat dissipation performance of the mold is insufficient. After the concrete is poured, the heat of hydration accumulates and can easily lead to local stress concentration, which aggravates the deformation of the mold and affects the internal density of the sleeper. At the same time, traditional concrete sleeper production molds are mostly fixed steel mold structures, which are formed by integral welding or bolt splicing. Although they can meet the basic forming requirements, the forming speed is relatively slow.

[0004] The applicant argues that the shortcomings are: when the equipment is in use, it is inconvenient to observe the concrete production at different heights or to air-dry it separately, thus reducing the practicality and production efficiency of the equipment. At the same time, most equipment uses relatively harsh and complicated methods for demolding, which may cause deformation or damage to the equipment or sleepers, thereby reducing the convenience of the equipment.

[0005] To address this issue, we propose a concrete sleeper production mold. Utility Model Content

[0006] The purpose of this utility model is to provide a concrete sleeper production mold to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a concrete sleeper production mold, comprising a production mold body, One end of the production mold body is provided with a square groove, and a sealing plate is slidably inserted inside the square groove. Both sides of one end of the production mold body are fixed with fixing plates, and one end of the fixing plate is fixed with a limit frame. An operating plate is fixed below one end of the production mold body, and a rotating rod is rotatably mounted on the bearing in the middle position of the operating plate. An adjusting plate is threadedly connected to the surface of the rotating rod, and springs are fixed on both sides of one end of the adjusting plate.

[0008] Preferably, the square groove is provided in multiple sets, and a waterproof strip is provided inside one end of the square groove. The surface of the waterproof strip is in contact with the surface of one end of the sealing plate. Through the use of the waterproof strip, leakage of water or concrete during mixing can be avoided.

[0009] Preferably, one end of the sealing plate is provided with a sealing plate, and the inner walls of both ends of the sealing plate are in contact with the surface of one end of the production mold body. Both sides of one end of the sealing plate are provided with handles. By using the sealing plate in conjunction, the sealing plate can be prevented from moving into the production mold body, and the sealing plate can be moved out according to the handles.

[0010] Preferably, the inner walls of the sealing plate are provided with limiting grooves on both sides, and the surface of the limiting groove is in contact with the surface of the limiting frame. When the limiting groove is in contact with the surface of the limiting frame, the sealing plate is moved out of the production mold body and placed on the surface of the production mold body, so as to observe and ventilate the concrete at the position of the limiting groove.

[0011] Preferably, limiting plates are provided on both sides of the other end of the adjusting plate, and the inner wall surface of the limiting plate is in contact with the surface of the operating plate. By using the limiting plates in conjunction, the stability of the adjusting plate movement can be improved, and the shaking or tilting of the adjusting plate during movement can be avoided.

[0012] Preferably, the distance between the rotating rod and the production mold body is greater than the width of the sealing plate, which makes it easier for workers to remove the sealing plate.

[0013] Preferably, both ends of the spring are provided with positioning discs. The two sets of positioning discs are fixedly connected to the surfaces of the adjusting plate and the sealing plate, respectively. The positioning discs can make the spring more stable when fixedly connected. At the same time, according to the connection and cooperation of the springs, when the inner wall of the adjusting plate is in contact with one end of the operating plate, multiple sets of sealing plates can be moved out by the cooperation of multiple sets of springs, thereby facilitating the demolding of the sleeper.

[0014] This utility model provides a concrete railway sleeper production mold, which has the following beneficial effects: Based on the concrete production situation, select the appropriate sealing plate, then hold the handle to move the sealing plate outward, and move the sealing plate left or right according to actual needs. When the limiting groove is in contact with the surface of the limiting frame, the position of the sealing plate can be fixed. Through the above operation, the position of concrete in different locations can be checked, and the location can be dried separately, thereby improving the practicality and work efficiency of the equipment.

[0015] By rotating the lever, the adjusting plate is moved outward. At this time, the spring moves the sealing plate outward. When the inner wall surface of the adjusting plate is in contact with the surface of one end of the operating plate, the surfaces of multiple sealing plates can be completely separated from the inside of the square groove. This facilitates the demolding of the formed sleeper and avoids damage to the sleeper or equipment caused by forceful demolding. At the same time, the above operation is relatively simple.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This embodiment proposes a concrete railway sleeper production mold. Example 1

[0021] like Figure 1 and Figure 2 As shown, this embodiment proposes a concrete sleeper production mold, including a production mold body 1. One end of the production mold body 1 has a square groove, and a sealing plate 3 is slidably inserted inside the square groove. Both sides of one end of the production mold body 1 are fixed with fixing plates 5, and one end of the fixing plate 5 is fixed with a limit frame 6. There are multiple sets of square grooves. One end of the square groove is provided with a waterproof strip 2, and the surface of the waterproof strip 2 is in contact with the surface of one end of the sealing plate 3. One end of the sealing plate 3 is provided with a sealing plate, and the inner walls of both ends of the sealing plate are in contact with the surface of one end of the production mold body 1. Both sides of one end of the sealing plate are provided with handles. Both sides of the inner wall of the sealing plate are provided with limit grooves 4, and the surface of the limit grooves 4 is in contact with the surface of the limit frame 6.

[0022] In the above embodiment, the concrete at different heights can be viewed and observed through the combined use of multiple sets of square grooves and sealing plates 3. The use of waterproof strips 2 can prevent leakage of water and concrete during mixing inside the equipment. When the sealing plate is in contact with the surface of the production mold body 1, the sealing plate 3 is completely in contact with the surface of the square groove. At the same time, the sealing plate can prevent the sealing plate 3 from entering the production mold body 1 and causing the sleeper to deform. When the operator holds the handle and pulls it outward, the sealing plate 3 can be moved from inside the groove. At this time, the sealing plate 3 can be moved to the left or right to the corresponding position of the fixing plate 5 according to the actual observation position. Then, the limiting groove 4 is in contact with the surface of the limiting frame 6 to restrict the position of the sealing plate 3, thereby allowing the exposed concrete to be observed and drying accelerated. Example 2

[0023] like Figure 3 and Figure 4 As shown, based on the same concept as the above embodiment, this embodiment also proposes: an operating plate 7 is fixed below one end of the production mold body 1, and a rotating rod 8 is rotatably rotatable at the middle position of the operating plate 7. An adjusting plate 9 is threadedly connected to the surface of the rotating rod 8, and springs 10 are fixed on both sides of one end of the adjusting plate 9. Limiting plates are provided on both sides of the other end of the adjusting plate 9, and the inner wall surface of the limiting plate is in contact with the surface of the operating plate 7. The distance between the rotating rod 8 and the production mold body 1 is greater than the width of the sealing plate 3. Positioning discs are provided at both ends of the springs 10. The two sets of positioning discs are fixedly connected to the surfaces of the adjusting plate 9 and the sealing plate, respectively. A handle is provided at one end of the rotating rod 8, and the surface of the handle is in contact with the surface of one end of the operating plate 7.

[0024] The spring 10 used in this application is subjected to inward pressure, which compresses it and returns it to its original length after being released. This is a product that can be purchased directly on the market. Its principle and connection method are existing technologies known to those skilled in the art, so they will not be described in detail here.

[0025] In the above embodiment, by rotating the throttle, the rotating rod 8 can be rotated, thereby causing the adjusting plate 9 to move forward or backward at the bottom of the inner wall of the operating plate 7. With the cooperation of the limiting plate, the movement position of the adjusting plate 9 can be restricted. At the same time, when the adjusting plate 9 moves, its inner wall ends are in contact with the two end surfaces of the operating plate 7, thereby improving the stability of the adjusting plate 9 during movement. With the cooperation of the spring 10, when the inner wall surface of the adjusting plate 9 is in contact with one end surface of the operating plate 7, the spring 10 can pull the sealing plate 3 outward according to its elastic force, thereby allowing multiple sets of sealing plates 3 to disengage from the inside of the groove. At this time, the sleeper can be demolded better, thereby improving the efficiency of the equipment. With the cooperation of the positioning plate, the spring 10 can be more firmly connected to the adjusting plate 9 and the sealing plate 3.

[0026] Working principle: When using the equipment, first pour concrete and the required liquid into the inside of the production mold body 1 and stir it. When the height of the concrete is close to the height of the production mold body 1, the excess concrete on the top of the production mold body 1 can be scraped away from this position using a scraper. When the concrete has dried for a certain period of time, the operator can select the appropriate height to be observed, hold the handle and move the sealing plate 3 outward. The sealing plate 3 can be moved to the left or right according to the position to be observed. The sealing plate 3 is moved so that the limiting groove 4 and the limiting frame 6 are in contact. At this time, the position of the sealing plate 3 can be fixed. The operator can then check the position or speed up the drying process. When the sleeper is completely air-dried, turn the handle to rotate the lever 8, which in turn moves the adjusting plate 9 outward. At this time, according to the connection between the spring 10 and the positioning plate, multiple sets of sealing plates 3 are moved out of the groove. When the adjusting plate 9 moves to one end of the operating plate 7, the surface of the sealing plate 3 can be completely separated from the inside of the square groove, which facilitates a quicker demolding operation of the sleeper. The above is the complete working principle of this utility model.
