Technical Field
[0001] The present application relates to the technical field of rail accessories, and in particular to a guide rail pressure plate assembly for coastal cities. Background Art
[0002] The operation of high-speed rail, intercity train, subway, gantry crane and other equipment requires the guidance of tracks or guide rails. After the track or guide rail is laid, it is usually necessary to use a pressure plate assembly to tighten and fix the track or guide rail.
[0003] The pressure plate assembly used in some coastal cities generally includes a pressure plate, a spring washer, an embedded bolt and a clamping nut. Part of the embedded bolt is cast in the cement sleeper, and the other part is exposed to the outside. When the laid track or guide rail is compressed, the pressure plate is sleeved on the protruding part of the embedded bolt; and a part of the pressure plate is pressed against the edge of the bottom side of the guide rail, and then the spring washer and the clamping nut are successively sleeved on the protruding part of the embedded bolt, and finally the clamping nut is tightened to compress the pressure plate. However, the size of the pressure plate is usually much larger than the size of the spring washer and the clamping nut, and the part of the pressure plate in contact with the guide rail does not contact the spring washer or the clamping nut, which makes the pressure plate's compression effect on the guide rail poor. Utility Model Content
[0004] In order to improve the clamping effect of the pressure plate assembly on the guide rail, the present application provides a guide rail pressure plate assembly for coastal cities.
[0005] The present application provides a guide rail pressure plate assembly for coastal cities, which adopts the following technical solution:
[0006] A guide rail pressure plate assembly for coastal cities includes a pressure plate body, a heterogeneous spring bar and a clamping bolt. The pressure plate body includes a clamping portion clamped to the guide rail and a mounting portion mounted on a cement sleeper. The heterogeneous spring bar partially abuts against the mounting portion, and the heterogeneous spring bar partially abuts against the clamping portion. The clamping bolt is used to clamp the heterogeneous spring bar onto the pressure plate body.
[0007] In order to improve the stability of the anisotropic elastic strip after the pressure plate body is pressed, the anisotropic elastic strip includes a U-shaped portion, a first arc portion connected to one end of the U-shaped portion, a first bent portion connected to the first arc portion away from the U-shaped portion, and a first bent leg connected to the first bent portion away from one end of the first arc portion, the first arc portion and the first bent leg are both located below the side of the U-shaped portion, the first arc portion abuts against the mounting portion, and the first bent leg abuts against the clamping portion.
[0008] The anisotropic elastic strip also includes a second arc portion connected to the other end of the U-shaped portion, a second bent portion connected to the second arc portion away from the U-shaped portion, and a second bent leg connected to the second bent portion away from one end of the second arc portion, the second arc portion and the second bent leg are both located below the other side of the U-shaped portion, the second arc portion abuts against the mounting portion, and the second bent leg abuts against the clamping portion.
[0009] In order to enable the anisotropic elastic strip to transmit most of the pressure to the clamping force guide rail for clamping after being subjected to pressure, the side of the mounting portion away from the clamping portion is bent to form an arc-shaped blocking groove for the arc tops of the first arc portion and the second arc portion to be embedded.
[0010] In order to enable the clamping bolt to drive the anisotropic elastic strip to clamp the pressure plate body, the clamping bolt passes through the middle of the U-shaped portion, and the mounting portion is provided with a waist-shaped hole for the clamping bolt to pass through.
[0011] The clamping bolt is sleeved with a gasket abutting against the top of the U-shaped portion.
[0012] In order to increase the contact area between the anisotropic elastic strip and the gasket, a fitting plane that fits with the gasket is provided on one side of the U-shaped portion close to the gasket.
[0013] In order to increase the contact area between the anisotropic elastic strip and the clamping portion to increase the clamping force of the anisotropic elastic strip on the clamping portion, the first bent leg and the second bent leg are both provided with abutment planes that fit the clamping portion on one side close to the clamping portion.
[0014] In order to make the contact area between each pressing plate body and the guide rail consistent when pressing the guide rail, a blocking strip abutting against the edge of the side wall of the guide rail is provided on the side of the mounting portion away from the anisotropic elastic strip.
[0015] In order to increase the service life of the clamping assembly in coastal cities, the outer surfaces of the clamping plate body, the anisotropic elastic strips and the clamping bolts are sprayed with anti-corrosion paint.
[0016] In summary, the present application includes at least one of the following beneficial technical effects:
[0017] The first bent leg and the second bent leg abut against the pressing part, and the pressing part abuts against the guide rail to press the guide rail, so that the anisotropic elastic strip can apply a pressing force to the pressing part, thereby improving the stability of the pressing plate body after pressing the guide rail;
[0018] The first arc portion and the second arc portion are both located in the arc blocking groove and are limited. After the clamping bolt is tightened to make the anisotropic elastic strips subjected to pressure, the first bent leg and the second bent leg are subjected to pressure and move toward the direction close to the guide rail, and then the pressure is transmitted to the position where the clamping portion is closer to the guide rail, further improving the stability of the clamping plate body after clamping the guide rail.
[0019] The setting of the fitting plane increases the contact area between the gasket and the anisotropic elastic strip, so that the clamping bolt can apply more pressure to the anisotropic elastic strip. At the same time, the setting of the abutment plane increases the contact area between the first bent support leg and the second bent support leg and the clamping part, thereby increasing the pressure on the clamping part.

[0024] The following is combined with Figure 1-3 This application is described in further detail.
[0025] The present application embodiment discloses a guide rail pressure plate assembly for coastal cities. Figure 1The guide rail pressure plate assembly for coastal cities includes a pressure plate body 1, an anisotropic spring bar 2 and a clamping bolt 3. A part of the pressure plate body 1 clamps the guide rail; the other part is clamped and fixed to the cement sleeper by the clamping bolt 3 and the anisotropic spring bar 2. A part of the anisotropic spring bar 2 abuts against the part of the pressure plate body 1 located on the cement sleeper; the other part abuts against the part of the pressure plate body 1 located on the guide rail. The clamping bolt 3 passes through the anisotropic spring bar 2 and the pressure plate body 1 and is fixed to the cement sleeper, so that the anisotropic spring bar 2 clamps the part of the pressure plate body 1 located on the guide rail onto the guide rail. In addition, since the air humidity in coastal cities is relatively high and the air contains a lot of corrosive moisture, the outer surfaces of the pressure plate body 1, the anisotropic spring bar 2 and the clamping bolt 3 are sprayed with anti-corrosion paint, thereby increasing the service life of the pressure plate body 1, the anisotropic spring bar 2 and the clamping bolt 3.
[0026] Reference Figure 2 The clamping plate body 1 includes a clamping portion 11 and a mounting portion 12. The clamping portion 11 is located on the side of the mounting portion 12 close to the guide rail. The height of the top plane of the clamping portion 11 is higher than the height of the top plane of the mounting portion 12 to form a step shape, and the clamping portion 11 and the mounting portion 12 are integrally formed. The clamping portion 11 will abut against the guide rail to clamp the guide rail, and the mounting portion 12 is located on the cement sleeper and is clamped and fixed on the cement sleeper. The anisotropic elastic bar 2 partially abuts against the top of the mounting portion 12; and partially abuts against the top of the clamping portion 11. Among them, a blocking strip 13 is integrally formed at the junction of the mounting portion 12 and the clamping portion 11 on the side away from the anisotropic elastic bar 2. During installation, the blocking strip 13 will abut against the side edge of the guide rail, thereby making it difficult for the clamping portion 11 to continue to approach the inside of the guide rail, so that each clamping plate body on the guide rail can be installed in place.
[0027] Reference Figure 2 and Figure 3 The anisotropic elastic bar 2 is formed by bending a circular cylinder, and the anisotropic elastic bar 2 includes a U-shaped portion 21, a first arc portion 22, a first bending portion 23, a first bending leg 24, a second arc portion 25, a second bending portion 26, and a second bending leg 27. The first arc portion 22, the first bending portion 23, and the first bending leg 24 are sequentially connected to each other and located on one side of the U-shaped portion 21, and the second arc portion 25, the second bending portion 26, and the second bending leg 27 are sequentially connected to each other and located on the other opposite side of the U-shaped portion 21. The first arc portion 22 and the second arc portion 25 are symmetrically arranged; the first bending portion 23 and the second bending portion 26 are symmetrically arranged; the first bending leg 24 and the second bending leg 27 are symmetrically arranged. The U-shaped portion 21 , the first arc portion 22 , the first bending portion 23 , the first bending leg 24 , the second arc portion 25 , the second bending portion 26 and the second bending leg 27 are all integrally formed.
[0028] In detail, there is a certain distance between the U-shaped portion 21 and the pressure plate body 1, one end of the first arc portion 22 is connected to one end of the opening of the U-shaped portion 21, and the other end of the first arc portion 22 is bent and extended toward the arc of the U-shaped portion 21, and the first arc portion 22 is bent and formed below the side of the U-shaped portion 21. One end of the first bent portion 23 is connected to one end of the first arc portion 22 away from the U-shaped portion 21, and the other end extends toward the arc of the U-shaped portion 21, and the first bent portion 23 first bends upward close to the U-shaped portion 21; and then bends downward away from the U-shaped portion 21. One end of the first bent leg 24 is connected to one end of the first bent portion 23 away from the first arc portion 22; the other end extends horizontally in the direction close to the U-shaped portion 21.
[0029] Reference Figure 2 and Figure 3 One end of the second arc-shaped portion 25 is connected to the other end of the opening of the U-shaped portion 21, and the other end of the second arc-shaped portion 25 is bent and extended toward the arc of the U-shaped portion 21, and the second arc-shaped portion 25 is bent and formed below the other side of the U-shaped portion 21. One end of the second bent portion 26 is connected to the end of the second arc-shaped portion 25 away from the U-shaped portion 21, and the other end extends toward the arc of the U-shaped portion 21, and the second bent portion 26 first bends upward close to the U-shaped portion 21; and then bends downward away from the U-shaped portion 21. One end of the second bent leg 27 is connected to the end of the second bent portion 26 away from the second arc-shaped portion 25; the other end extends horizontally in the direction close to the U-shaped portion 21.
[0030] Reference Figure 2 and Figure 3 Since the anisotropic elastic strip 2 is formed by bending a cylinder, the side of the mounting portion 12 away from the pressing portion 11 is bent upward to form an arc-shaped baffle, and the arc-shaped baffle and the mounting portion 12 form an arc-shaped blocking groove 14. The arc tops of the first arc-shaped portion 22 and the second arc-shaped portion 25 are both embedded in the arc-shaped blocking groove 14, and the first arc-shaped portion 22 and the second arc-shaped portion 25 are both in contact with the arc-shaped baffle. When the anisotropic elastic strip 2 is subjected to pressure, the first arc-shaped portion 22 and the second arc-shaped portion 25 are not easy to move under the action of the arc-shaped blocking groove 14, and the first bent leg 24 and the second bent leg 27 are more likely to deform and move in the direction close to the guide rail, so that the pressing portion 11 can be more stably pressed on the guide rail.
[0031] Among them, the first bent leg 24 and the second bent leg 27 are both polished with abutment surfaces 28 on one side close to the clamping portion 11. The first bent leg 24 and the second bent leg 27 can increase their contact area with the clamping portion 11 through the abutment surface 28, thereby improving the clamping effect.
[0032] Reference Figure 2 and Figure 3The clamping bolt 3 passes through the middle of the U-shaped portion 21, and a waist-shaped hole 15 is provided on the mounting portion 12 for the threaded end of the clamping bolt 3 to pass through. After the threaded end of the clamping bolt 3 passes through the mounting portion 12, it is threadedly installed on the casting cast in the cement sleeper. A gasket 31 is sleeved on the clamping bolt 3, and the gasket 31 will abut against the top of the U-shaped portion 21 (the side of the U-shaped portion 21 away from the mounting portion 12). The top of the U-shaped portion 21 is polished with a fitting plane 29, and the gasket 31 will fit on the fitting plane 29, thereby increasing the contact area between the U-shaped portion 21 and providing a more stable pressure.
[0033] The implementation principle of a guide rail clamp assembly for coastal cities in the embodiment of the present application is as follows: during installation, the clamping portion 11 abuts against the guide rail to clamp the guide rail, and the mounting portion 12 is located on the cement sleeper. Then, the anisotropic elastic strip 2 is placed on the clamping plate body 1, so that the first bent leg 24 and the second bent leg 27 abut against the clamping portion 11, and the first arc portion 22 and the second arc portion 25 are both located in the arc blocking groove 14. Finally, the threaded end of the clamping bolt 3 passes through the middle of the U-shaped portion 21 and passes through the waist-shaped hole 15 through the mounting plate and then is threadedly installed on the cement sleeper, and then the clamping bolt 3 is screwed so that the anisotropic elastic strip 2 presses the clamping plate body 1 onto the guide rail. In this process, since the first bent leg 24 and the second bent leg 27 are both located on the clamping portion 11, pressure can be directly applied to the clamping portion 11, thereby improving the stability of the clamping plate body 1 after being pressed onto the guide rail.
[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
