Description

Technical Field

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

[0002] In subway track maintenance, track gauge adjustment is a crucial step in ensuring the safe and smooth operation of trains. Existing track gauge adjustment tools mainly include gauge tie rods and diagonal braces. When using these tools, the diagonal braces are secured to the rail webs on both sides. The extension of the screw increases the support force of the diagonal braces, thereby changing the lateral displacement of the rails and adjusting the track gauge. However, the current track gauge adjustment tools, whether gauge tie rods or diagonal braces, have the following drawbacks: When adjusting the track gauge, one side of the diagonal brace must be supported on the rail web of the other side. Each gauge adjustment requires at least three people working together. Furthermore, these tools can only enlarge the track gauge, not reduce it, resulting in significant limitations in their use and making them unsuitable for on-site maintenance work.

[0003] To meet the needs for efficient, convenient, and precise track gauge adjustment, we have developed an innovative subway track gauge adjustment device. Utility Model Content

[0004] The purpose of this utility model is to provide a subway track gauge adjustment device, which has the advantages of effectively improving the quality and efficiency of track gauge adjustment operations. It solves the problems of the original tools, which require one side of the inclined support to be supported on the rail web of the other side when adjusting the track gauge, and require at least three people to work together for each track gauge adjustment. Furthermore, the original tools can only enlarge the track gauge and cannot reduce it.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a subway track gauge adjustment device, comprising a central rotating cylinder, with adjusting screws threadedly connected to both the left and right sides of the inner cavity of the central rotating cylinder. A sleeve is fitted onto the surface of the adjusting screw at the end away from the central rotating cylinder. A left adjusting bracket is fixedly installed on the top of the left sleeve, and a right adjusting bracket is fixedly installed on the top of the right sleeve. A pin is provided through the rear side of the sleeve, and the front side of the pin extends to the front side of the sleeve. A limiting sleeve is fixedly welded to the front side of the sleeve, and a scale plate is provided through the inner cavity of the limiting sleeve. A bolt is installed on the front side of the limiting sleeve.

[0006] Preferably, anti-slip sleeves are fixedly fitted on both the left and right sides of the surface of the central rotating cylinder, and a handle insertion hole is opened at the center of the surface of the central rotating cylinder, with the handle insertion holes being staggered from left to right.

[0007] Preferably, an adjusting handle is inserted into the handle socket, and one end of the adjusting screw has a pin hole through which the pin passes.

[0008] Preferably, there are two left and two right adjustment brackets, which are symmetrically welded to the top of the sleeve, and the scale plate has scale lines evenly distributed on its surface.

[0009] Preferably, a fixing pin is provided through the front side of the bottom of the pin, and a nut is threaded onto the top of the fixing pin through the pin.

[0010] Preferably, the surface of the bolt is threaded to the connection between the bolt and the limiting sleeve, the rear side of the bolt penetrates the limiting sleeve and is in close contact with the front side of the scale plate, and the surface of the scale plate is in contact with the inner wall of the limiting sleeve.

[0011] Preferably, the top of both the left and right adjustment brackets is provided with a track body, the left adjustment bracket is in contact with the left side of the track body, and the top of the right adjustment bracket is engaged with the track body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The main structure of this utility model is made of high-strength aluminum alloy. Aluminum alloy has the characteristics of low density and light weight. Compared with traditional steel materials, it greatly reduces the weight of the device itself. This makes it easier and more convenient for workers to carry and operate the device. Especially when the work position needs to be moved frequently, it can significantly reduce labor intensity and improve work efficiency. At the same time, the lightweight design does not affect the strength and durability of the device. After special treatment, aluminum alloy has good fatigue resistance and corrosion resistance. It can withstand various stresses and environmental influences in subway track adjustment operations, ensuring long-term stable and reliable operation.

[0014] 2. This utility model adopts a completely mechanical design, eliminating complex electronic components and hydraulic systems. Its operating principle is based on simple mechanical transmission and lever principles. Operators can achieve precise adjustment of track gauge with simple operation. This design makes the operation threshold of the device extremely low. Even new employees without extensive experience in operating electronic or hydraulic equipment can quickly get started and master the use of the adjustment device after simple training. Moreover, the mechanical structure of the device is more stable and less susceptible to electromagnetic interference, circuit failures or hydraulic leaks, making it more reliable in actual use and reducing the risk of work interruption due to equipment failure.

[0015] 3. This utility model possesses excellent track gauge adjustment capabilities, easily handling both large track gauge adjustments and precise adjustments for small track gauges. Through a uniquely designed adjustable mechanism, the adjustment range and force can be flexibly controlled based on actual track gauge deviations. When increasing the track gauge, specific mechanical components can be used to push the rails outwards, achieving a significant increase in gauge. Conversely, when decreasing the track gauge, the corresponding mechanism can be reversed, precisely adjusting the track gauge to the design standard range. This flexible adjustment function makes it suitable for subway track maintenance work under various line conditions and track gauge variations, greatly improving the device's versatility and practicality.

[0016] 4. All components of this utility model adopt a detachable design, and each key component can be easily disassembled for individual inspection, repair or replacement without the need for complex disassembly and reassembly of the entire device. This not only shortens equipment maintenance time and reduces maintenance difficulty, but also effectively reduces downtime caused by equipment maintenance and improves the continuity of track maintenance work. At the same time, the detachable component design also facilitates regular maintenance of the device. Workers can easily perform cleaning, lubrication and tightening operations on each component to ensure that the device is always in good working condition and extend the service life of the equipment.

[0017] 5. This utility model has the ability to adjust the level, which can keep the height of both ends of the device the same. Therefore, when adjusting the track, the track pulling trajectory will not deviate, which greatly improves the accuracy of track gauge adjustment. No manual fine-tuning is required afterward, thus improving work efficiency. Attached Figure Description

[0024] Please see Figures 1-5 A subway track gauge adjustment device includes a central rotating cylinder 1. Adjusting screws 5 are threadedly connected to both the left and right sides of the inner cavity of the central rotating cylinder 1. A sleeve 6 is sleeved on the surface of the end of the adjusting screw 5 away from the central rotating cylinder 1. A left adjusting bracket 10 is fixedly installed on the top of the left sleeve 6, and a right adjusting bracket 9 is fixedly installed on the top of the right sleeve 6. A pin 11 is inserted through the rear side of the sleeve 6, and the front side of the pin 11 extends through to the front side of the sleeve 6. A limiting sleeve 15 is fixedly welded to the front side of the sleeve 6. A scale plate 7 is inserted through the inner cavity of the limiting sleeve 15. By setting the scale plate 7, the height of the adjusting screws 5 on both sides of the central rotating cylinder 1 can be detected, so that the adjusting screws 5 can be easily adjusted to a level state. A bolt 14 is installed on the front side of the limiting sleeve 15. By setting the bolt 14, the scale plate 7 can be fixed inside the limiting sleeve 15, so that the scale plate 7 will not shift after adjustment.

[0025] The main structure of this device is made of high-strength aluminum alloy.

[0026] Please see Figure 1 and Figure 2 Anti-slip sleeves 2 are fixedly fitted on both the left and right sides of the surface of the central rotating cylinder 1. The anti-slip sleeves 2 are made of polyurethane coating (friction coefficient μ≥0.8). A handle insertion hole 4 is opened at the center of the surface of the central rotating cylinder 1. By setting the handle insertion hole 4, the adjustment handle 3 can be easily inserted, thereby realizing the installation of the adjustment handle 3. The handle insertion holes 4 are staggered on the left and right sides. The staggered distribution can enhance the stress of the central rotating cylinder 1 and avoid the central rotating cylinder 1 from breaking due to the reduction of strength caused by opening parallel handle insertion holes 4.

[0027] Please see Figure 1 and Figure 2 An adjusting handle 3 is installed inside the handle insertion hole 4. One end of the adjusting screw 5 has a pin hole through which the pin 11 passes. By setting the pin hole, the pin 11 can be easily inserted, so that the adjusting screw 5 can be fixed inside the sleeve 6 to achieve installation. It can also be quickly disassembled and assembled by fixing pin 12 and nut 13.

[0028] Please see Figure 3 There are two left adjustment brackets 10 and two right adjustment brackets 9, which are symmetrically welded to the top of the sleeve 6. The scale plate 7 has scale lines evenly distributed on its surface.

[0029] Please see Figure 5 A fixing pin 12 is provided through the front side of the bottom of the pin 11, and the top of the fixing pin 12 passes through the pin 11 and is threaded with a nut 13.

[0030] Please see Figure 5 The surface of bolt 14 is threaded to the connection between it and the limiting sleeve 15. The rear side of bolt 14 passes through the limiting sleeve 15 and is in close contact with the front side of scale plate 7. The surface of scale plate 7 is in contact with the inner wall of limiting sleeve 15.

[0031] Please see Figure 1 and Figure 2 The top of both the left adjustment bracket 10 and the right adjustment bracket 9 is provided with a track body 8. The left adjustment bracket 10 is in contact with the left side of the track body 8, and the top of the right adjustment bracket 9 is engaged with the track body 8.

[0032] In use, place the device between the two track bodies 8 and observe whether the scales on the scale plates 7 on both sides are the same at the bottom of the limiting sleeve 15. If they are not the same, loosen the bolt 14 and adjust the scales on the two scale plates 7 at the bottom of the limiting sleeve 15 to be the same. Then the gauge adjustment operation can be performed. When it is necessary to increase the gauge, the adjusting handle 3 can be rotated by a specific mechanical component. Under the action of the thread, the adjusting screw 5 inside moves outward, thereby driving the outer end of the sleeve 6 to push the track body 8, and then push it outward to achieve a larger increase in gauge. When it is necessary to reduce the gauge, the corresponding mechanism can be operated in reverse so that the left adjusting bracket 10 and the right adjusting bracket 9 pull the two track bodies 8 inward, which can accurately adjust the gauge to the design standard range.

[0033] In summary, this subway track gauge adjustment device, through the central rotating cylinder 1, adjusting screw 5, sleeve 6, right adjusting bracket 9, left adjusting bracket 10, pin 11, and bolt 14, solves the problems of the original tools when adjusting the track gauge. These tools required one side of the inclined support to be supported on the rail web of the other side, and each gauge adjustment required at least three people to work together. Furthermore, the original tools could only enlarge the track gauge and could not reduce it.
