[0027] See also Figure 1-Figure 3 The present application provides a new technical solution: a high-precision measuring device for high-speed rail track gauge, comprising a track gauge ruler 1, one end of the track gauge ruler 1 is fixedly connected to a fixed seat 3, two sets of walking mechanisms are arranged below the fixed seat 3, the walking mechanisms are used to make the track gauge ruler 1 walk on the rail, the other end of the track gauge ruler 1 is slidably connected to a sliding seat 2, the sliding direction of the sliding seat 2 is parallel to the length direction of the track gauge ruler 1, and a set of walking mechanisms is also arranged below the sliding seat 2, which is used to drive the track gauge ruler 1 to walk on another rail;

[0028] The traveling mechanism below the fixed seat 3 is clamped on the rail by a clamping assembly, so as to improve the stability of the track gauge 1 during its traveling on the rail. The clamping assembly includes clamping blocks 32 distributed on both sides of the rail. The outer clamping blocks 32 are fixedly connected to the traveling mechanism, and the inner clamping blocks 32 are slidably connected in the bottom slide groove of the fixed seat 3. The rail can be clamped by adjusting the position of the inner clamping blocks 32. Conductive blocks 33 are arranged on the inner sides of the two clamping blocks 32. Conductive heads 34 are connected to the inner sides of the conductive blocks 33. The conductive heads 34 are in contact with the side faces of the rails, and the contact parts are arranged in an arc shape. The conductive blocks 33 and the conductive heads 34 are made of conductive materials, and can be specifically made of copper, which has the characteristics of good wear resistance and conductive performance.

[0029] In some embodiments, a battery pack 4 and a display light 5 are provided on the upper side of the fixing seat 3, and the two conductive blocks 33 are respectively connected to the battery pack 4 and the display light 5 through the wires 31. The number of the display lights 5 is two, and the two display lights 5 are respectively connected to the two groups of walking mechanisms below the fixing seat 3; when in use, the rail is regarded as a conductor, and the conductive heads 34 on the clamping blocks 32 on both sides of the rail are in contact with the side of the rail. The wires 31, the conductive blocks 33, the conductive heads 34 and the display lights 5 form a closed circuit, and power is provided by the battery pack 4, so that the wires 31 on both sides are in a connected state, and the display lights 5 connected to the wires 31 are in an on state. When one side of the conductive heads 34 on both sides is not in contact with the rail, the circuit is in an open state, and the display lights 5 are in an off state. The staff can judge whether the fixing seat 3 is tilted according to the turning on and off of the display lights 5, reduce the tilt of the track gauge 1, reduce the relative displacement between the track gauge 1 and the rail, and improve the accuracy of detection.

[0030] Specifically, the clamp block 32 is made of rubber insulating material to prevent workers from feeling a tingling sensation on their fingers during debugging when the electric wire 31 leaks electricity, thereby reducing the potential safety hazard of the device.

[0031] In some embodiments, a slide groove 321 is provided below the fixing seat 3 , and the inner clamping block 32 is slidably connected inside the slide groove 321 .

[0033] Furthermore, the fixing plate 322 is internally threadedly connected with a rotating rod 323, one side of the rotating rod 323 is rotatably connected to the push plate 326, and the other side is provided with a rotating handle 324, by rotating the rotating handle 324, the push plate 326 can be pushed to move toward the inner clamping block 32, when the track gauge 1 is tilted during movement and the display light 5 is off, the push plate 326 is moved toward the inner clamping block 32 to compress the spring 327, and the spring 327 pushes the inner clamping block 32 to slide in the slide groove 321 under the action of the elastic function, so that the conductive head 34 on the inner clamping block 32 is in close contact with the side of the rail, so that the fixing seat 3 and the rail are in a parallel state, thereby driving the track gauge 1 and the rail to be in a vertical state.

[0034] In some embodiments, the walking mechanism includes a mounting frame 10, which is fixedly installed under the sliding seat 2 and the fixed seat 3 respectively. The mounting frame 10 is rotatably connected to a roller 9. When in use, the walking mechanism is placed between two rails, and the bottom of the roller 9 is in contact with the upper surface of the rail.

[0035] In some embodiments, a limit plate 11 is fixedly installed on the inner side of the walking mechanism below the sliding seat 2, and a rotating wheel 12 is rotatably connected below the limit plate 11. One side of the rotating wheel 12 contacts the side of the rail, which can make the walking mechanism run on the rail more smoothly.

[0036] In some embodiments, a display 6 and a handle 7 are provided on the track gauge 1. The display 6 is used to display measurement data. A tension spring is provided inside the track gauge 1, connecting the handle 7 and the sliding seat 2. The handle 7 can pull the sliding seat 2 to slide on the track gauge 1 along the length direction of the sliding seat 2 through the tension spring.

[0037] In some embodiments, a push rod 8 is provided on the front side of the track gauge ruler 1 for pushing the track gauge ruler 1 to move on the rail.

[0038] Working principle: When a high-precision measuring device for the track gauge of a high-speed railway is used, first place the fixed seat 3 on one side of the rail, so that the roller 9 on the running mechanism under the fixed seat 3 contacts the surface of the rail, and then pull the sliding seat 2 through the pull handle 7 to make the running mechanism under the sliding seat 2 contact the other side of the rail, and then make the conductive head 34 on the outer clamping block 32 on the clamping assembly contact one side of the rail, and then synchronously adjust the front and rear adjustment mechanisms of the fixed seat 3 to make the conductive head 34 on the inner clamping block 32 contact the other side of the rail, and connect it to the display light 5 and the battery pack 4 through the wire 31 to form a circuit, so that the display light 5 is in the on state, and the staff can determine whether the fixed seat 3 is tilted by observing the on and off state of the display light 5, and then determine whether the track gauge 1 is tilted, and adjust the adjustment mechanism to make 01 vertical to the two rails to ensure measurement accuracy.
