Description

Technical Field

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

[0002] The technological development of rapid track adjustment clamps for railways stems from the core need for "efficient and accurate track positioning" in railway track maintenance and construction. Early railways (especially conventional railways) relied on manually operated mechanical tools (such as lead screw supports and crowbar clamps) for track adjustment. These tools, based on purely mechanical transmission principles, were suited to the basic requirements of conventional railways at the time regarding gauge and elevation adjustment accuracy (allowing for an error of 5-10 mm) and operational efficiency (each adjustment taking several hours).

[0003] For example, the national authorized patent announcement number CN221589099U discloses a railway track gauge adjustment device, including a ballast bed; a fixed rail is fixedly connected to the top of the ballast bed; a sliding bracket is slidably connected to the surface of the fixed rail; an adjusting rail is fixedly connected to the top of the sliding bracket; movable seats are slidably connected to both sides of the ballast bed; a bidirectional screw is rotatably connected to the surface of the movable seat; the ballast bed supports the fixed rail, the sliding bracket can slide on the fixed rail and be fixed to the adjusting rail, thereby driving the adjusting rail to move; at the same time, the bidirectional screw rotates to drive the L-shaped adjusting block to move, which is used to drive the limiting bracket to move, and the limiting bracket is locked on the adjusting rail to achieve the function of changing the track gauge of the adjusting rail, avoiding the use of a heavy-duty track adjuster, reducing labor intensity, and thus improving the adjustment efficiency.

[0004] However, the aforementioned railway track quick adjustment clamp has a complex structure and lacks a moving mechanism, which means that multiple people are needed to move or push the device each time the track spacing is adjusted, affecting the adjustment efficiency. Utility Model Content

The two first clamping blocks are respectively threaded to the left and right helical segments of the bidirectional screw, and stabilizing rods are slidably connected to both ends of the first clamping blocks.

[0011] As a preferred embodiment of this utility model, two second clamping blocks are slidably connected to the outer surfaces of the two stabilizing rods respectively. The second clamping blocks slide along the outer surfaces of the stabilizing rods. Connecting plates are welded to both sides of the two first clamping blocks respectively, and the extended ends of the connecting plates are attached to one end of the surface of the second clamping blocks.

[0012] As a preferred embodiment of this utility model, the connecting plate and the second clamping block are respectively provided with the same threaded hole at one end of their outer surfaces. The threaded hole is internally threaded with a positioning bolt. The two sets of first clamping blocks and second clamping blocks are respectively attached to one side of the track for clamping and fixing the track from both sides and adjusting the spacing.

[0027] Example 1

[0028] The railway track quick-adjustment clamp provided in this embodiment, such as Figures 1-4 As shown, the system includes: a clamp assembly 3 for adjusting the spacing of the tracks 102 and a foundation 1. Concrete sleepers 101 are mounted on the foundation 1. The tracks 102 are located at both ends of the upper surface of the concrete sleepers 101. An adjusting frame 2 is detachably connected to one end of the upper surface of the concrete sleepers 101. A bidirectional screw 202 is rotatably connected to the inner wall of the adjusting frame 2. The clamp assembly 3 is threaded onto the surface of the bidirectional screw 202, enabling adjustment of the spacing between the two tracks 102. Fixing plates 205 are installed on the lower half of both sides of the inner wall of the adjusting frame 2. Moving wheels 204 are rotatably mounted at both ends of the lower surface of the adjusting frame 2. The adjusting frame 2 can move via the moving wheels 204 to allow the fixing plates 205 to adhere to the surface of the concrete sleepers 101 and be fixed by bolts. A drive motor 201 is located at one end of the outer surface of the adjusting frame 2. The output shaft of the drive motor 201 is connected to one end of the bidirectional screw 202. Two stabilizing rods 203 are fixedly installed on the inner wall of the adjusting frame 2, with the bidirectional screw 202 located between the two stabilizing rods 203.

[0029] By adjusting the frame 2, the moving wheel 204, the bidirectional screw 202, and the clamp assembly 3, when the track 102 in the newly built railway needs to be adjusted in terms of spacing, the moving wheel 204 facilitates the movement of the adjusting frame 2, reducing the physical exertion caused by manual handling. During the movement of the adjusting frame 2, the fixing plate 205 installed on one side of the inner wall passes over the surface of the concrete sleeper 101. When it moves to the required adjustment position, the bolt is inserted and passes through the preset mounting holes of the fixing plate 205 and the concrete sleeper 101 to fix the adjusting frame 2. Then, by starting the drive motor 201, the output shaft of the motor drives the bidirectional screw 202 to rotate, which in turn drives the clamp assembly 3 with the threaded connection on the outer surface to move, ensuring the precise adjustment of the spacing between the two tracks 102.

[0030] Example 2

[0031] The railway track quick-adjustment clamp provided in this embodiment, such as Figures 3-4As shown, the fixture assembly 3 includes two first clamping blocks 301, which are threadedly connected to the left and right helical segments of the bidirectional screw 202, respectively. Stabilizing rods 203 are slidably connected to both ends of the first clamping blocks 301. Two second clamping blocks 303 are slidably connected to the outer surfaces of the two stabilizing rods 203, and slide along the outer surfaces of the stabilizing rods 203. Connecting plates 302 are welded to both sides of the two first clamping blocks 301, and the extended ends of the connecting plates 302 are attached to one end of the surface of the second clamping blocks 303. The connecting plates 302 and the second clamping blocks 303 each have identical threaded holes at one end of their outer surfaces, and positioning bolts 304 are threaded into these holes. The two sets of first clamping blocks 301 and second clamping blocks 303 are respectively attached to one side of the track 102 for clamping and fixing the track 102 from both sides and adjusting the spacing.

[0032] Through the design of the first clamping block 301, the second clamping block 303, and the connecting plate 302, when the bidirectional screw 202 rotates, the two first clamping blocks 301 move closer or further away from each other synchronously along the left and right spiral segments of the bidirectional screw 202. At the same time, the two ends of the first clamping blocks 301 slide in cooperation with the stabilizing rod 203. The stabilizing rod 203 can prevent the first clamping blocks 301 from rotating with the bidirectional screw 202. When the two first clamping blocks 301 move and fit against one side of the track 102, the drive motor 201 stops rotating. The worker pushes the second clamping block 303 to fit against the other side of the track 102 and against the first clamping block 301. Then, the positioning bolt 304 is threaded into the same threaded hole provided in the connecting plate 302 and the second clamping block 303 to complete the fixing and clamping of the track 102. Then, the distance between the two tracks 102 is adjusted, thereby achieving efficient calibration and stable fixing of the distance between the tracks 102 and reducing manual labor consumption.

[0033] In summary, the railway track quick adjustment fixture provided in this embodiment has the following advantages: with the moving wheels 204 and the fixture assembly 3, no multiple people are needed to carry it during use, reducing physical exertion, making it easy to push and move to the work site, and effectively improving the efficiency of spacing adjustment.

[0034] In use, when the track spacing of the track 102 in a newly built railway needs to be adjusted, the adjustment frame 2 can be easily moved by the moving wheels 204, reducing the physical exertion caused by manual handling. During the movement of the adjustment frame 2, the fixing plate 205 installed on one side of the inner wall passes over the surface of the concrete sleeper 101. When it moves to the required adjustment position, the bolt is inserted, and the bolt passes through the preset mounting holes of the fixing plate 205 and the concrete sleeper 101 to complete the fixing of the adjustment frame 2. Then, by starting the drive motor 201, the bidirectional screw 202 is driven to rotate, and the two first clamping blocks 301 move along the left and right sides of the bidirectional screw 202. The right-hand helical segment axes move synchronously closer or further apart, while the two ends of the first clamping block 301 slide in cooperation with the stabilizing rod 203. The stabilizing rod 203 can prevent the first clamping block 301 from rotating with the bidirectional screw 202. When the two first clamping blocks 301 move and fit against one side of the track 102, the drive motor 201 stops rotating. The worker pushes the second clamping block 303 to fit against the other side of the track 102 and against the first clamping block 301. Then, the positioning bolt 304 is threaded into the same threaded hole provided in the connecting plate 302 and the second clamping block 303 to complete the fixing and clamping of the track 102.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
