Description

Technical Field

[0001] This utility model relates to the field of railway track technology, specifically to a railway track gauge adjustment device. Background Technology

[0002] Railway lines are a flexible system. Over long-term use by trains, the track spacing can change, affecting train operation safety.

[0003] A search of patent application number CN202223421655.5 reveals that this utility model provides a railway track gauge adjustment device for driving a second clamping assembly to move along a first direction to adjust the railway track gauge. The control unit is mounted on a support beam and electrically connected to the adjustment assembly. This utility model aims to solve the problem of low efficiency in manual track gauge adjustment of existing railway lines. However, it fails to detect excessive track gauge movement in a timely manner, necessitating subsequent adjustments and thus hindering work efficiency.

[0004] Further searching patent application number CN202420159537.1 reveals that this utility model belongs to the field of railway track technology, specifically a railway track gauge adjustment device. This device avoids the need for heavy track levelers, reducing labor intensity and improving adjustment efficiency. In contrast, the aforementioned two applications, CN202223421655.5 and CN202420159537.1, require workers to carry the mechanical gauge adjuster and track leveler to the adjustment position when adjusting the distance between two tracks. This increases the workload and makes it difficult to detect excessive track gauge movement in a timely manner, necessitating subsequent adjustments and hindering work efficiency.

The moving rod and the variable rod are fixedly connected.

[0008] Preferably, a positioning pin is provided at the bottom of the sleeve, the top end of the positioning pin is fixedly connected to the push rod, and a guide rod is fixedly provided at the top end of the push rod.

[0014] Beneficial effects

[0015] This utility model provides a railway track gauge adjustment device. Compared with the prior art, it has the following advantages:

[0016] 1. This railway track gauge adjustment device uses a motor to simultaneously rotate a round rod and move a horizontal bar downwards. When the round rod rotates, the sliding rod moves linearly along the groove, changing the position of one end of the changing rod. This makes both the changing rod and the moving rod horizontal, allowing the track to move. When the horizontal bar moves downwards, the pushing rod moves downwards, simultaneously causing the positioning pin below the pushing rod to move downwards. This allows the positioning pin to be embedded in the ground, fixing the sleeve and preventing movement when the track contacts the sleeve, thus increasing stability. This prevents excessive movement during adjustment and allows for simultaneous operation, improving work efficiency.

[0017] 2. This railway track gauge adjustment device can stretch the measuring tape by moving the sleeve. The measuring tape is set so that the distance the sleeve moves can be known, so that the sleeve can be accurately positioned in the designated position, which facilitates subsequent operations.

[0023] 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.

[0024] Please see Figure 1-24. This utility model provides a technical solution: a railway track gauge adjustment device, including a bracket 1, with adjustment mechanisms 2 on both sides of the bracket 1, and holes 3 inside the bracket 1 extending to the top surface of the bracket 1. Slide grooves 4 are provided on both sides of the holes 3, and the connection between the slide grooves 4 and the holes 3 is connected.

[0025] The adjustment mechanism 2 includes a fixed plate 201. A motor 202 is installed below one end of the fixed plate 201, and a threaded rod 203 is installed at the end of the output shaft of the motor 202. A lifting plate 211 is fixedly installed at the bottom of the fixed plate 201. A round rod 204 is installed below the lifting plate 211. A gear 205 is installed on the outer side of the round rod 204. Telescopic rods 206 are fixedly installed on both sides of the bracket 1. A sleeve 207 is installed at one end of the telescopic rod 206. A push rod 208 is installed at the top of the sleeve 207. The bottom end of the push rod 208 extends into the inside of the sleeve 207 and is movably connected to the sleeve 207. A variable rod 209 is installed between the bracket 1 and the sleeve 207. A moving rod 210 is installed at one end of the variable rod 209. Both the moving rod 210 and the variable rod 209 are inclined. The moving rod 210 and the variable rod 209 are fixedly connected.

[0026] A crossbar 213 is fixedly installed at the bottom of the fixed plate 201. One end of the guide rod 212 extends into the interior of the crossbar 213 and is slidably connected to the crossbar 213. A connecting plate 214 is provided at one end of the fixed plate 201, and a threaded rod 203 passes through the connecting plate 214 and is threadedly connected to the connecting plate 214. The bottom end of the lifting plate 211 is located on one side of the gear 205. A toothed rail is provided on the surface of the lifting plate 211 near the gear 205, and the toothed rail meshes with the gear 205. A sliding groove 4... The internal part is provided with a sliding rod 215, which is movably connected to the slide groove 4. A round rod 204 passes through the sliding rod 215 and is connected to the sliding rod 215 by a thread. A measuring tape 216 is fixedly provided on one side of the sleeve 207. A round block 217 is provided at one end of the variable rod 209 and the moving rod 210. The round block 217 at the variable rod 209 is fixedly connected to the sliding rod 215, and the round block 217 at the moving rod 210 is fixedly connected to the telescopic rod 206.

[0027] Please see Figure 1 and 3 The bottom of the sleeve 207 is provided with a positioning pin 5, the top of the positioning pin 5 is fixedly connected to the push rod 208, and the top of the push rod 208 is fixedly provided with a guide rod 212.

[0028] During operation, the entire assembly is moved to the center of the track. Then, the sleeve 207 is moved, causing the positioning pin 5 and the top push rod 208 to move as well. This increases the distance between the sleeve 207, positioning pin 5, and bracket 1, positioning pin 5 and sleeve 207 in the designated position. The movement of the sleeve 207 also stretches the measuring tape 216. The measuring tape 216 indicates the distance the sleeve 207 has moved, ensuring it is precisely positioned for subsequent operations. Then, the motor 202 is used. Since the output shaft of the motor 202 is connected to the threaded rod 203, the motor 202 drives the threaded rod 203 to rotate. As the threaded rod 203 rotates... During the process, the connecting plate 214, which is threadedly connected to the threaded rod 203, moves downward, causing the fixed plate 201, which is fixedly connected to the connecting plate 214, to move downward simultaneously. This pushes the lower crossbar 213 and the lifting plate 211 downward. When the crossbar 213 moves downward, the toothed rail on the surface of the crossbar 213 moves downward simultaneously. Because the toothed rail meshes with the gear 205, the downward movement of the toothed rail causes the gear 205 to rotate, and the round rod 204, which is fixedly connected to the gear 205, rotates simultaneously, improving work efficiency. The round rod 204 rotates inside the hole 3. During the rotation of the round rod 204, the round rod 204 is connected to the sliding rod 215 via threads. Next, the circular rod 204 allows the sliding rod 215 to move, causing it to move linearly along the slide groove 4. This movement of the sliding rod 215 simultaneously moves the circular block 217 at the end of the variable rod 209, gradually bringing the circular block 217 at the variable rod 209 and the circular block 217 at the moving rod 210 to the same horizontal line. Since both the variable rod 209 and the moving rod 210 are movably connected to their corresponding circular blocks 217, they can change from an inclined state to a horizontal state, allowing the circular block 217 at the moving rod 210 to move. The circular block 217 at the moving rod 210 is fixedly connected to one end of the telescopic rod 206, making the telescopic rod 209... The length of 6 is increased because the railway track is now located between the telescopic rod 206 and the sleeve 207. The increased length of the telescopic rod 206 can push the railway track to move, allowing for adjustments. When the crossbar 213 moves downward, the guide rod 212 and the push rod 208 connected to the crossbar 213 move downward simultaneously. Because the bottom end of the push rod 208 extends into the inside of the sleeve 207, the downward movement of the push rod 208 causes the positioning pin 5 in the sleeve 207 to move downward simultaneously, allowing the positioning pin 5 to be grounded and fixing the sleeve 207. This prevents movement when the subsequent track contacts the sleeve 207, increasing stability.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
