The rail is fixed by using trapezoidal vertical clamps and "convex" font-shaped anti-slip blocks and pressure plate positioning blocks. Force joint controls the rails not to move and prevents the rails from being squeezed with the guide rails.

Description
Technical Field
[0001] The utility model relates to a rail fixing device on a track scale and belongs to the technical field of rail fixing devices. Background Art
[0002] In the railway transportation of coal preparation plants, in order to weigh the weight of train loads, a track scale with a weighing sensor is usually installed on the foundation under the rail. The sinking amplitude of the rail on the track scale is converted into the weight of the train load by the weighing sensor. The connection between the two ends of the rail on the track scale and the guide rails on both sides is fixed with a special track clamp plate with a machine-milled end face, and a gap is left between the rail and the guide rail on the track scale. When the train passes through the track on the track scale, because the material of the track clamp plate is less hard than the rail, the huge impact force generated by the train will continue to act on the track clamp plate, causing the track clamp plate to wear and deform, and the rail on the track scale will be squeezed together with the guide rail, so that it cannot sink and trigger the weighing sensor, resulting in the inability to weigh the weight of the train load. Therefore, it is necessary to improve the rail fixing device on the track scale to prevent the rail on the track scale from moving back and forth, causing the track scale to be unable to weigh. Summary of the invention

[0005] Preferably, the vertical clamping plate has a trapezoidal cross-section.
[0006] Preferably, the vertical cross-section of the vertical splint has a trapezoidal vertical surface width of 54 mm, a lower angle of 104 degrees, an upper angle of 118 degrees, and the outer sides of the angles are all rounded with a radius of 10 mm.

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the following will be combined with the attached Figures 1 to 6 The technical solution of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, but not all of them. Based on the described embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.
[0019] like Figure 1 and Figure 4 As shown, a rail fixing device on a track scale includes a vertical clamp plate 1, an anti-sliding block 2 and a pressure plate positioning block 3. The upper part of one side of the pressure plate positioning block 3 is fixedly connected to the vertical clamp plate 1, and the lower part is fixedly connected to the anti-sliding block 2 in a "convex" shape. The surfaces of the vertical clamp plate 1 and the pressure plate positioning block 3 are both provided with through holes 9.
[0020] like Figure 3 , Figure 5As shown, a positioning hole 5 is milled at the bottom of the rail 8 on the track scale, a screw hole 4 is set in the middle, the anti-sliding block 2 is installed on the positioning hole 5 at the bottom of the rail 8, the rail 8 is clamped, the pressure plate positioning block 3 is fixed to the fixed thread hole reserved on the foundation with bolts, and the vertical clamping plate 1 is installed on the screw hole 4 in the middle of the rail 8. The three components of the rail fixing device can effectively prevent the rail 8 from moving forward and backward.
[0021] like Figure 6 As shown, the connection between the two ends of the rail 8 on the track scale and the guide rails 7 on both sides is a machine-milled end surface, fixed with a track clamp 6, and a gap is left between the rail 8 on the track scale and the guide rail 7, and the fixing bolts need to cooperate with the mounting holes to ensure that the rail 8 on the track scale can fully sink to trigger the weighing sensor, thereby achieving the purpose of weighing. In the utility model, the three components fix the rail 8 so that it does not move forward and backward, that is, it prevents the rail 8 on the track scale from being squeezed together with the guide rail 7, ensuring that the track scale can weigh the weight of the train normally.
[0022] like Figure 2 As shown, the cross section of the vertical splint 1 is trapezoidal, and the trapezoidal shape is conducive to buffering the impact force on the track 8 when the train passes. The vertical splint 1 has a trapezoidal cross section with a vertical width of 54mm, a lower angle of 104 degrees, and an upper angle of 118 degrees. The outer sides of the angles are all provided with fillets with a radius of 10mm. The specifications of the vertical splint 1 are set to be similar to the specifications of the contact surface of the rail 8, so that the contact surface of the vertical splint 1 and the rail 8 fit together, which is conducive to the fixation of the rail 8.
[0023] like Figure 1 , Figure 3 As shown, the pressure plate positioning block 3 is welded together with the vertical clamping plate 1 and the anti-sliding block 2, which has a simple process, increases the firmness of the utility model, and is also conducive to the fixation of the track.
[0024] In this embodiment, the vertical clamp 1 is made of 10# steel plate, the pressure plate positioning block 3 is made of 30# steel plate, and the anti-sliding block 2 is made of 16# manganese steel plate. The material specifications and hardness used in each component of the utility model ensure the normal use of the track scale and the rails will not move forward and backward.
[0025] In actual installation and use of the utility model, generally the vertical clamping plate 1, the pressure plate positioning block 3 and the anti-sliding block 2 should have the same inclination as the contact surface of the rail.
[0026] The utility model has obvious effect through use. The screws can compact the positioning block 2, and then there are more welding points, and there is no gap at the bottom. The protruding part of the bottom plate is completely embedded in the notch, and the positioning block cannot be lifted up. At the same time, the vertical plate 1 can constrain the guide rail, which can effectively prevent the displacement and track deviation phenomenon.
[0027] The above is an implementation of the present utility model. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
