The track is usually composed of two balanced rails. In the process of rail production, when the pit defect is generated on the surface of the rail, the pit depth measuring scale is used to detect whether the vertical depth of the pit is over standard.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0028] Please see Figures 1-4 This utility model provides a gauge for measuring the depth of pits on the surface of a rail, including a rail body 2. A gate-shaped fixed mounting frame 1 is installed across the upper end of the rail body 2 to facilitate the installation and stable operation of a digital depth measuring instrument 113. The digital depth measuring instrument 113 is installed in the middle of the fixed mounting frame 1 through a moving component so that it can move left and right to measure. The digital depth measuring instrument 113 can be a TECLOCK model depth measuring instrument for measurement.

[0029] The movable component includes a movable slide 111 that runs vertically through the fixed mounting bracket 1. Limiting slides 114 that run through the fixed mounting bracket 1 are provided on both sides of the movable slide 111. A movable slider 112 is installed inside the movable slide 111, and limiting sliders 115 on both sides of the movable slider 112 are slidably connected to the limiting slide 114. A digital depth measuring instrument 113 is mounted on the movable slider 112. Through the connection between the limiting sliders 115 and the limiting slide 114, the movable slider 112 can drive the digital depth measuring instrument 113 to move left and right, allowing it to move left and right relative to the surface of the rail body 2. The recess is used for measurement to facilitate left and right adjustments, thus improving measurement efficiency. A fixed screw 116 is connected to one side of the movable slider 112, passing through the limiting slide groove 114. A shim 117 is installed on the outside of the fixed screw 116. A self-tightening nut 118 is installed on the outside of the shim 117 and connected to the fixed screw 116. By rotating the self-tightening nut 118, the shim 117 can move inward inside the fixed screw 116, thus fixing the movable slider 112 and preventing it from moving left and right during forward and backward measurements, resulting in better measurement accuracy.

[0030] Preferably, the bottom measuring needle of the digital depth measuring instrument 113 is provided with a groove 119 inside, and a ball bearing 120 is rolled inside the groove 119. This makes it easier for the bottom needle of the digital depth measuring instrument 113 to be moved under force during measurement, making it easier to move. This makes it easier for the lower needle to measure during movement, resulting in more measuring surfaces and better effect and efficiency.

[0031] The fixed mounting frame 1 has cylindrical magnets 12 rotatably connected to the upper surfaces of the rail body 2 on both sides inside. The magnets 12 fix the fixed mounting frame 1 to the upper surface of the rail body 2. The fixed mounting frame 1 can be pushed back and forth to work when the magnets 12 can roll. The fixed mounting frame 1 has mounting plates 11 symmetrically connected to both sides inside. The mounting plates 11 are arranged in pairs of different lengths to correspond to the different sizes of the two sides of the rail body 2, which helps to enhance the stability of the fixed mounting frame 1. The mounting plates 11 are connected to the rotating rod 13 through the connecting bearing 14. The magnets 12 are installed in the middle of the rotating rod 13, so that the magnets 12 can rotate to work. This allows the fixed mounting frame 1 to be pushed to move while being fixed to the upper surface of the rail body 2, so that it can be used to measure several positions. The fixed mounting frame 1 has stabilizing components installed on both sides and connected to the rail body 2 to make it move stably.

[0032] The stabilizing component includes threaded holes 15 penetrating both sides of the fixed mounting bracket 1. A lead screw 16 is connected inside the threaded holes 15, and a knob 17 is connected to the outside of the lead screw 16. A pusher 18 is connected to the inside of the lead screw 16 via a bearing. A rotating rod 19 is installed inside the pusher 18, and a clamping wheel 110 is rotatably mounted on the outside of the rotating rod 19 to contact the rail body 2. By rotating the knob 17, the lead screw 16 rotates and pushes the pusher 18 inward through the threaded holes 15, causing the inner clamping wheel 110 to contact the rail body 2. This clamping action on both sides improves the stability of the fixed mounting bracket 1. Furthermore, the rotation of the clamping wheel 110 facilitates the movement of the fixed mounting bracket 1 on the rail body 2, enabling the fixed mounting bracket 1 to move and perform measurements at multiple points.

[0033] Working principle: In use, the fixed mounting bracket 1 is placed on the upper end of the rail body 2, so that the adsorption magnets 12 on both sides are adsorbed on the rail body 2. Then, the knob 17 is turned so that the lead screw 16 rotates inside the connecting threaded hole 15, thereby causing the internal pusher 18 to push the clamping wheel 110 to contact the rail body 2, so that the side of the fixed mounting bracket 1 is fixed. Then, the digital display depth measuring instrument 113 can be adjusted so that the lower ball 120 contacts the surface of the rail body 2 for measurement. By pushing the sliding slider 112 to move left and right, the left and right measurement points can be adjusted. And under the rotation of the adsorption magnets 12 and the clamping wheel 110, the fixed mounting bracket 1 can move back and forth, thereby allowing the digital display depth measuring instrument 113 to measure back and forth, thus completing the work.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
