Technical Field
[0001] This utility model belongs to the technical field of concrete turnout sleepers, specifically a concrete turnout sleeper for a single turnout. Background Technology
[0002] A turnout sleeper is a key device used on railway turnouts to connect or cross two or more sleepers on a plane. It is an indispensable component of the railway sleeper system. Its core function is to guide locomotives and rolling stock to smoothly switch from one track to another or successfully cross another track. Its structural characteristics directly affect the efficiency and safety of railway use. Different types of turnouts have different structural characteristics, including ordinary single turnouts, ordinary single turnouts, ordinary single turnouts, and ordinary single turnouts, etc. Among them, the most widely used in practice is the turnout sleeper. In order to ensure the stable and long-term use of turnout sleepers, it is necessary to improve them.
[0003] Meanwhile, the UIC60 rail No. 15 movable point turnout with application number CN202121267621.8 includes a pre-embedded concrete turnout sleeper and a set of switch mechanisms, a set of movable point frogs, and guide rails mounted on it. The set of switch mechanisms includes two stock rails and two switch rails. The movable point frog includes two wing rails, one long frog, and one short frog, which are mounted on a roller support assembly. Therefore, by improving the combination method between the working edge of the straight stock rail and the curved switch rail, the service life of the curved switch rail can be increased, harmful space in the frog can be eliminated, and the turning force of the curved switch rail and the movable point rail can be reduced. Furthermore, by pre-welding a section of rail after die forging both the curved switch rail and the movable point rail, sufficient guide rail length is ensured when replacing old turnouts on-site or during secondary welding.
[0004] However, the following problems were found in the implementation of the relevant technology: Although the existing equipment can avoid wear on the side walls of the sleeper connection to increase service life, it cannot buffer the vibration at the bottom of the connection, which makes the bottom easy to wear and the service life will still be affected. Utility Model Content
[0005] To address the problems mentioned in the background section, this utility model provides a concrete sleeper for a single turnout. The connection of the concrete sleeper is reinforced by multiple sets of fixing screws, while the springs on its sidewalls can buffer vibrations and reduce the frequency of friction at the bottom of the sleeper to reduce wear. It has the advantages of being less prone to wear at the bottom and having a longer service life.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a concrete turnout sleeper for a single turnout, comprising a concrete sleeper body, wherein the concrete sleeper body is formed by casting two sets of intersecting concrete sleepers, and a reinforcing plate is installed at the connection between the two sets of concrete sleepers, and multiple reinforcing holes are arranged side by side on the top of the reinforcing plate, and reinforcing screws are inserted into the reinforcing holes. A spring is sleeved on the side wall of the reinforcing screw, and both ends of the spring are connected to support rings, with the upper support ring abutting against the bottom of the head of the reinforcing screw and the lower support ring abutting against the top of the reinforcing plate.
[0007] Preferably, the reinforcing plate is flush with the bottom of the concrete sleeper, and a concrete layer is poured at the joint between the reinforcing plate and the concrete sleeper.
[0008] Preferably, the sidewall of the reinforcing plate is fixedly connected with multiple reinforcing ribs in a row, and the reinforcing ribs are flush with the corresponding side of the reinforcing plate.
[0009] Preferably, multiple reinforcing rods are inserted side by side between the symmetrical inner walls of the concrete sleeper, and the reinforcing rods are cylindrical structures made of chrome-plated iron.
[0010] Preferably, a vibration damping ring is installed at the connection between the reinforcing rod and the concrete sleeper, and the vibration damping ring is flush with the corresponding side of the concrete sleeper.
[0011] Preferably, a warning sticker is adhered to the outer wall of the concrete sleeper.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model reinforces the connection with the ground by using multiple reinforcing screws. The springs on the side walls of the reinforcing screws will buffer the vibration of the concrete sleeper. Multiple sets of springs in conjunction with the reinforcing screws can effectively reduce vibration, so the bottom of the concrete sleeper connection is less prone to wear, effectively extending the service life of the equipment.
[0014] 2.

[0020] 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.
[0021] like Figures 1 to 4 As shown, this utility model provides a concrete turnout sleeper for a single turnout, including a concrete sleeper body. The concrete sleeper body is formed by casting two sets of intersecting concrete sleepers 1, and a reinforcing plate 2 is installed at the connection of the two sets of concrete sleepers 1. The top of the reinforcing plate 2 has multiple reinforcing holes arranged side by side, and a reinforcing screw 3 is movably inserted into the reinforcing holes. The tail of the reinforcing screw 3 has a conical structure, which can increase the connection stability of the equipment when drilled into the ground. A spring 4 is sleeved on the side wall of the reinforcing screw 3. Both ends of the spring 4 are connected to support rings 5. The support rings 5 are made of circular stainless steel, and the spring 4 is a stainless steel spring. The use of stainless steel is more durable and less prone to damage. The upper support ring 5 abuts against the bottom of the head of the reinforcing screw 3, and the lower support ring 5 abuts against the top of the reinforcing plate 2. When vibration is transmitted to the surface of the reinforcing screw 3, the two support rings 5 will move relative to each other and compress the spring 4. The spring 4 will therefore produce elastic deformation and buffer the vibration. Together with the reinforcing screw 3, it can effectively reduce vibration and avoid wear on the bottom of the equipment, which will affect its service life.
[0022] Specifically, the bottom of the reinforcing plate 2 is flush with the bottom of the concrete sleeper 1 to avoid increasing the difficulty of installation, and a concrete layer is poured at the joint between the reinforcing plate 2 and the concrete sleeper 1 to ensure a stable connection between the reinforcing plate 2 and the concrete sleeper 1.
[0023] Furthermore, multiple reinforcing ribs 6 are fixedly inserted side by side on the side wall of the reinforcing plate 2. The multiple reinforcing ribs 6 can increase the structural strength of the reinforcing plate 2, so that the reinforcing plate 2 can effectively withstand the transverse stress, and the reinforcing ribs 6 are flush with the corresponding side of the reinforcing plate 2.
[0024] Furthermore, multiple reinforcing rods 7 are inserted side by side between the symmetrical inner walls of the concrete sleeper 1. These multiple reinforcing rods 7 can increase the structural strength of the concrete sleeper 1, enabling it to effectively withstand lateral stress. Moreover, the reinforcing rods 7 are cylindrical structures made of chrome-plated iron, making them easier to install and less prone to damage.
[0025] It is worth noting that a vibration damping ring 8 is installed at the connection between the reinforcing rod 7 and the concrete sleeper 1, which can decompose some of the vibration and further enhance the structural strength of the concrete sleeper 1. The vibration damping ring 8 is flush with the corresponding side of the concrete sleeper 1.
[0026] It is worth noting that a warning sticker 9 is affixed to the outer wall of the concrete sleeper 1. The surface of the warning sticker 9 is marked with warning content to warn others not to damage it.
[0027] Working principle: When the equipment is installed in a designated location, the surface of the equipment will vibrate when a train passes by. The vibration will be transmitted through the concrete sleeper 1 to the reinforcing plate 2 and then to the surface of the reinforcing screw 3. At this time, the two support rings 5 on the side wall of the reinforcing screw 3 will move relative to each other and compress the connected spring 4. The spring 4 will therefore undergo elastic deformation and buffer the vibration. The structure of multiple sets of springs 4 and reinforcing screw 3 can effectively reduce the vibration and prevent the bottom of the concrete sleeper 1 from being worn, which would affect the service life of the equipment.
