Therefore, in view of the above situation, it is urgent to develop a track gauge adjustment device that is convenient for adjusting the spacing between the guide rails, accurately controls the distance size, and saves manpower, so as to overcome the shortcomings in current practical applications and meet current needs.

[0016] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example

[0018] See also Figures 1 to 4 In the embodiment of the utility model, a track gauge adjustment device includes a support 1, the support 1 is in an "I" shape, a handle 2 is installed on the top of the support 1, and two walking mechanisms 3 are installed on the support 1. When moving, the support 1 is supported by the walking mechanism 3, and the support 1 is pushed away by the handle 2, so as to facilitate the movement of the entire device. A width adjustment mechanism 4 is installed on the support 1, and a scale plate 5 is installed on the upper side of the width adjustment mechanism 4. The scale plate 5 passes through the support 1. When in use, the support 1 is placed on the ground between the two guide rails, and the two guide rails are pushed by the width adjustment mechanism 4. The spacing between the guide rails is observed by the scale plate 5, so as to facilitate accurate control and adjustment of the distance between the guide rails;

[0019] The walking mechanism 3 includes: a hydraulic cylinder 301, a lifting frame 302 and casters 303. The hydraulic cylinder 301 is fixed on the support 1. The telescopic rod of the hydraulic cylinder 301 is connected to the lifting frame 302. Two casters 303 are installed at the bottom of the lifting frame 302. When moving, the hydraulic cylinder 301 drives the lifting frame 302 to move downward, and the lifting frame 302 drives the casters 303 to lift the support 1. The casters 303 can move the entire device. When it does not need to move, the hydraulic cylinder 301 drives the lifting frame 302 and the casters 303 to move upward, so that the bottom of the support 1 is attached to the ground, increasing the contact area with the ground and being more stable.

[0020] The width adjustment mechanism 4 includes: a hydraulic motor 401, a first gear 402, a second gear 403, a transmission shaft 404, a first thread 405, a second thread 406, a first thread sleeve 407, a second thread sleeve 408, a limit rod 409, a push plate 410 and a pointer 411. The hydraulic motor 401 is fixed in the support 1. The first gear 402 is installed on the output shaft of the hydraulic motor 401. The lower side of the first gear 402 is installed with a second gear 403 that rotates with it. The second gear 403 is installed on the transmission shaft 404. The shaft 404 is rotatably connected to the support 1. The left half of the transmission shaft 404 is provided with a first thread 405, and the right half of the transmission shaft 404 is provided with a second thread 406. A first thread sleeve 407 matching therewith is installed on the outer side of the first thread 405, and a second thread sleeve 408 matching therewith is installed on the outer side of the second thread 406. A limiting rod 409 penetrating the support 1 is installed on each of the first thread sleeve 407 and the second thread sleeve 408. The limiting rod 409 is slidably connected to the support 1, and the first thread sleeve 407 is fixed to the support 1 through the limiting rod 409. The movement of the first thread 405 and the second thread 406 is restricted so that they cannot rotate but can only move linearly. The first thread 405 and the second thread 406 have opposite rotation directions, so that when the transmission shaft 404 rotates, the first thread sleeve 407 and the second thread sleeve 408 move in opposite directions. A push plate 410 is installed on each of the first thread sleeve 407 and the second thread sleeve 408, and a pointer 411 is installed on each of the push plates 410. The pointer 411 points to the scale plate 5. When in use, the width adjustment mechanism 4 is placed between the two tracks, and then the hydraulic motor 40 1 drives the first gear 402 and the second gear 403 to rotate, and the second gear 403 drives the transmission shaft 404 to rotate, and the rotation of the transmission shaft 404 drives the first threaded sleeve 407 and the second threaded sleeve 408 to move toward each other, and the first threaded sleeve 407 and the second threaded sleeve 408 drive the two push plates 410 to move toward each other, and the push plates 410 push the tracks to adjust the spacing between the tracks. When adjusting, by observing the scales pointed to by the two pointers 411 on the scale plate 5, the difference between the two scales is the scale between the tracks, which is convenient for accurately controlling the spacing between the tracks.

[0021] The working principle of the utility model is: when the track gauge adjustment device is used, the support 1 is placed on the ground between the two guide rails, and then the first gear 402 and the second gear 403 are driven to rotate by the hydraulic motor 401, and the transmission shaft 404 is driven to rotate by the second gear 403, and the first threaded sleeve 407 and the second threaded sleeve 408 are driven to move toward each other by the rotation of the transmission shaft 404, and the two push plates 410 are driven to move toward each other by the first threaded sleeve 407 and the second threaded sleeve 408, and the rails are pushed by the push plates 410 to adjust the spacing between the rails. When adjusting, the scales pointed to by the two pointers 411 on the scale plate 5 are observed, and the difference between the two scales is the scale between the rails, which is convenient for accurately controlling the spacing between the rails. In addition, the width adjustment mechanism 4 can also be placed on the outside of a guide rail to push a single guide rail inward.
