Description

Technical Field

[0001] This utility model relates to the field of track clamping equipment, specifically to a simple tool for tight clamping of railway turnouts. Background Technology

[0002] As a key piece of equipment connecting railway lines, the tightness of the fit between the stock rail and the switch rail directly affects railway transportation safety. In railway transportation operations in factories and mines, turnouts play a vital role in guiding vehicle travel direction and enabling track switching, ensuring smooth vehicle passage between different tracks, and are of great significance to the efficient operation of the entire transportation system.

[0003] However, there are currently many problems with shunting operations in factories and mines. On the one hand, the shunting process is cumbersome, and due to turnout accidents or equipment malfunctions, turnout misalignment occurs frequently. If shunting personnel fail to notice this in time, derailment accidents can easily occur when vehicles pass through, posing serious safety hazards to production operations and potentially leading to production stoppages and huge economic losses.

[0004] On the other hand, existing methods for handling loose turnouts have significant drawbacks. One traditional method is to adjust the switch rod to restore a tight fit between the stock rail and the switch rail. However, railway transportation in factories and mines has extremely high time requirements, and maintenance personnel need a long time for repairs and adjustments, which disrupts normal operations and leads to a significant decrease in transportation efficiency. Another method is to use rail clips and spikes for temporary fixation. However, due to the heavy loads and severe vibrations of locomotives, molten iron cars, and other transport vehicles during operation, spikes and rail clips can easily loosen and fall off under such conditions, causing the stock rail and switch rail to become loose again, and the risk of derailment remains. This not only increases maintenance costs and safety risks but also makes it difficult to guarantee the stability and continuity of transportation operations.

[0005] In conclusion, the existing methods for handling loose turnouts cannot meet the needs of efficient and safe railway transportation in factories and mines, and a simpler and more reliable tool is urgently needed to solve this problem. Utility Model Content

[0006] In view of this, the present invention provides a simple tool for the tight fitting of railway turnouts. The tool can be fixed by placing the connecting rod under the switch rail and the stock rail and positioning the two connecting parts on both sides of the stock rail and the switch rail. The fasteners are used to prevent the connecting parts from moving to both ends and causing the switch rail and the stock rail to separate.

[0007] To solve the above-mentioned technical problems, this utility model provides a simple tool for tight clamping of railway turnouts, including a connecting rod with two sliding connectors. The two connectors are L-shaped. The connecting rod connects the connectors and limits their movement, allowing them to slide smoothly on the connecting rod. The connecting rod is placed below the switch rail and the fixed rail. The length of the connecting rod is greater than the combined width of the switch rail and the stock rail. One connector is located on one side of the switch rail and abuts against the side base surface of the switch rail. The other connector is located on the side base surface of the stock rail and abuts against the side base surface of the stock rail. After contact, the connectors are fixed to the connecting rod by fasteners to prevent the connectors from moving left and right on the connecting rod, which would prevent the connectors from properly clamping the stock rail and the switch rail.

[0008] The fastener includes a thread at the end of the connecting rod, a nut that rotates on the thread, and one of the connecting parts on one side of the nut. A washer is provided between the nut and one of the connecting parts to increase the friction between the nut and the connecting part, reducing the risk of separation between the switch rail and the base rail due to insufficient fastening force of the connecting parts caused by the nut loosening. The fastener also includes a limiting hole at the end of the connecting rod to block another connecting part. When the nut pushes one connecting part to move towards the other connecting part, the limiting hole can limit the other connecting part to prevent it from slipping off the connecting rod.

[0009] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0010] 1. Ensure railway transportation safety: Effectively solve the problem of poor contact between the switch point rail and the stock rail, avoid derailment accidents caused by poor contact between the switch point and the stock rail, eliminate safety hazards in production operations, ensure railway transportation safety, and prevent production stoppages and economic losses.

[0011] 2. Improve railway transportation efficiency: Compared with the traditional method of adjusting switch rods, this simple tool does not require long-term maintenance and debugging, will not disrupt normal operation, and can achieve close contact between switch rail and stock rail in a short time, thereby improving railway transportation efficiency.

[0012] 3. Reduced maintenance costs and safety risks: Unlike the traditional method of temporary fixing with clamps and spikes, this tool effectively prevents the connecting parts from loosening and falling off through fasteners and reasonable structural design, reducing the possibility of the main rail and switch rail not fitting tightly again, thus reducing maintenance costs and safety risks, and ensuring the stability and continuity of transportation operations.

[0013] 4. Easy to operate: The structure is simple and easy to operate. The operator only needs to place the connecting rod under the switch rail and the base rail, adjust the position of the connecting piece so that it abuts against the side base surface of the switch rail and the base rail respectively, and then fix it with fasteners. No complicated operation procedures or professional skills are required. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-2 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0018] like Figure 1 , 2 As shown:

[0019] This embodiment provides a simple tool for tightly fitting railway turnouts, used to ensure the switch rail and stock rail are properly aligned, reducing accidents during mine car operation. It includes a connecting rod 1, a metal rod located below the switch rail and stock rail, clamping and fixing them from below without affecting normal vehicle operation. Two sliding connectors 2, a first rail clamping block and a second rail clamping block, slide on the connecting rod 1. Both the first and second rail clamping blocks are L-shaped. This rail is located between the first and second rail blocks. The first rail block is located on the side of the switch rail and abuts against the base surface of the switch rail side. The second rail block is located on the side of the main rail and abuts against the base surface of the main rail side. When the inner surface of the switch rail and the main rail abuts, the first and second rail blocks are limited by fasteners to prevent the first and second rail blocks from moving on the connecting rod 1. This would prevent the first and second rail blocks from properly clamping the switch rail and the main rail, causing the switch rail and the main rail to separate and resulting in an accident.

[0020] like Figure 1 , 2As shown: The fastener includes a thread 3 located at the end of the connecting rod 1, with a nut 5 rotating on the thread 3. The fastener also includes a limiting block 6 located at the tail of the connecting rod 1. The limiting hole is integrally set with the connecting rod 1. The first locking block and the second locking block are located between the limiting block 6 and the nut 5. The first locking block is located on the side closer to the nut 5, and the second locking block is located on the side closer to the limiting block 6. When the nut 5 rotates, it pushes the first locking block toward the second locking block, so that the first locking block and the second locking block abut against the tip rail and the base rail.

[0021] like Figure 1 , 2 As shown: There is a washer 4 between the nut 5 and the first rail block. The washer 4 can increase the friction between the nut 5 and the first rail block, and prevent the track from vibrating when the vehicle passes by, which would cause the nut 5 to fall off more quickly and affect the service life.

[0022] Working principle: First, the connecting rod 1 is placed at the bottom of the switch rail and the base rail. Since the length of the connecting rod 1 is greater than the width of the switch rail and the base rail combined, it can ensure stable placement. Two L-shaped connecting pieces 2 slide on the connecting rod 1. One connecting piece 2 abuts against the base surface of the switch rail, and the other abuts against the base surface of the base rail, thereby clamping and holding the switch rail and the base rail together.

[0023] The fasteners are used to limit the position of the connecting piece 2. The end of the connecting rod 1 has a thread 3, and a nut 5 rotates on the thread 3. A washer 4 is placed between the nut 5 and one of the connecting pieces 2 to increase friction and prevent the nut 5 from loosening. When the nut 5 is rotated, the nut 5 pushes the connecting piece 2 it is in contact with to move towards the other connecting piece 2, while the limiting block 6 at the tail of the connecting rod 1 blocks and limits the other connecting piece 2 to prevent it from slipping off the connecting rod 1. Finally, the two connecting pieces 2 are fixed in a suitable position, so that the switch rail and the stock rail are tightly fitted and kept in a tight fit. This prevents the switch rail from separating from the stock rail due to the movement of the connecting pieces 2 during use, thereby ensuring the normal operation of the railway turnout and the safety of railway transportation.

[0024] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
