Description

Technical Field

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

[0002] During railway track maintenance, workers need to use handheld adapters to adjust and limit the track gauge. However, this involves moving the device between the rails. Existing adapters mostly consist of a central hydraulic rod and two side support blocks, using the constant length of the hydraulic rod to determine the distance between the two rails. However, the presence of gravel and sand on the ground makes moving the device difficult and hinders its movement, affecting the adapter's speed of advancement within the rails. Therefore, we have developed a new track gauge adjuster to solve these problems. (Utility Model Content)

[0003] To address the shortcomings of existing technologies, this utility model provides a rail gauge adjuster that facilitates the adjustment of rail spacing and maintains stable distance control during movement, thus solving the problems of traditional adjusters being inconvenient to move and cumbersome to operate.

[0031] This utility model provides a rail gauge adjuster. The concrete track bed and supporting guide rails serve as rigid supports for the hook plate and guide groove, preventing sinking and facilitating movement. A separate hexagonal wrench rotates the hexagonal head, which drives a worm gear to control the worm wheel's rotation. The worm wheel then drives a threaded rod to rotate. The threaded block moves under the limiting and guiding action of the guide groove, causing the movable rod and hook plate to move synchronously, controlling the spacing of the grooved rails. The combination of the worm gear and worm wheel has anti-reverse rotation characteristics, maintaining a stable fixed distance during movement.

[0034] The guide groove 200 supports the threaded rod 240 via the bearing seat 230, facilitating the rotation of the threaded rod 240. The threaded block 250 moves under the limiting and guiding action of the guide groove 200, causing the movable rod 260 and the hook plate 270 to move synchronously, controlling the spacing of the channel rails 110. Specifically, the guide groove 200 is equipped with a bearing seat 230, which is fitted with the threaded rod 240.

[0035] The adjustment assembly 300 utilizes a separate hex wrench to rotate the hex head 310. The hex head 310 drives the worm gear 320 to control the rotation of the worm wheel 330, which in turn drives the threaded rod 240 to rotate. The combination of the worm wheel 330 and the worm gear 320 has anti-reverse rotation characteristics, maintaining a stable distance during movement. Specifically, the adjustment assembly 300 includes a hex head 310, a worm gear 320 fixedly connected to the hex head 310, and a worm wheel 330 that mates with the worm gear 320.

The worm gear 320 and the worm wheel 330 are located inside the guide groove 200. The hook plate 270 is located at the bottom of the channel rail 110. The shaft portion of the worm wheel 330 is provided with a polygonal hole 331, and the rear end of the threaded rod 240 is provided with a polygonal head that mates with the polygonal hole 331.

[0036] Combination Figures 1-6 The specific usage process of the rail gauge adjuster in this embodiment is as follows: the concrete track bed 100 and the supporting guide rail 220 serve as rigid supports for the hook plate 270 and the guide groove 200, which can prevent sinking and facilitate movement. The threaded rod 240 is supported by the bearing seat 230, which facilitates the rotation of the threaded rod 240. The threaded block 250 moves under the limiting and guiding action of the guide groove 200, so that the movable rod 260 and the hook plate 270 move synchronously, controlling the spacing of the grooved rails 110. The hexagonal head 310 is rotated by a separate hexagonal wrench. The hexagonal head 310 drives the worm gear 320 to control the rotation of the worm wheel 330. The worm wheel 330 drives the threaded rod 240 to rotate. The combination of the worm wheel 330 and the worm gear 320 has the characteristic of anti-reverse rotation, which can maintain a stable distance during movement.
