Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a secondary clamping clamp for preventing track fasteners from bouncing. Background Technology

[0002] Rail elastic fasteners are elastic fastening devices that connect rails and sleepers. They are key components in track engineering. Their core structure includes components such as elastic clips, bolts, track spikes, gauge plates, and rubber pads. The elastic clips generate fastening pressure to fix the rails by bending and deforming, while the rubber pads buffer the impact energy of trains to achieve vibration reduction.

[0003] During use, the elastic component is subjected to great pressure due to mechanical vibration and gravity when the train passes over the track. After the train passes, the elastic component will move and shift when it rebounds. In severe cases, the elastic component may even bounce, causing it to fail to provide shock absorption. Therefore, this application provides a secondary clamping clamp to prevent the track fastener from bouncing in order to meet the requirements. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a secondary clamping fixture to prevent track fasteners from bouncing, thereby solving the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] The fixing assembly includes a fixing frame, an adjusting screw at the top of the fixing frame, a lifting plate rotatably connected to the bottom end of the adjusting screw, a limit groove on the outer wall of the fixing frame, a through groove on the inner wall of the limit groove, a connecting plate fixedly mounted on the outer wall of the lifting plate, a clamping plate fixedly mounted at the end of the connecting plate, a slot on the outer wall of the clamping plate, a first insert plate inserted into the inner wall of the slot, a first locking rod fixedly mounted on the outer wall of the first insert plate, a connecting screw at the top of the clamping plate, a second insert plate that can also be inserted into the inner wall of the slot, a second locking rod fixedly mounted on the outer wall of the second insert plate, and a first adjusting nut and a second adjusting nut threadedly connected to the outer wall of the adjusting screw.

[0008] The elastic component includes an elastic pad, an iron pad is tightly attached to the top of the elastic pad, and a rail pad is tightly attached to the top of the iron pad. Fastening bolts are provided on the top of the elastic pad, the iron pad, and the rail pad.

[0009] The number of fixing frames is two, and both fixing frames are symmetrically distributed along the top of the base, which is made of concrete.

[0010] The top of the fixing frame has a through hole, and the inner wall of the through hole is slidably connected to the outer wall of the adjusting screw.

[0011] Both sides of the fixed frame are fixedly equipped with support frames, and the support frames, fixed frames, and base form a triangular structure.

[0012] The top of the elastic pad, the iron pad, and the rail pad are all provided with round holes, and the inner wall of the round holes is threaded to the outer wall of the fastening bolt.

[0013] The bottom of the first adjusting nut is tightly fitted to the top of the fixing frame, and the top of the second adjusting nut is tightly fitted to the bottom of the fixing frame.

However, this is only for illustrative purposes and is not intended to limit this utility model to the specific structure, device and environment. According to specific needs, those skilled in the art can adjust or modify these devices and environments, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0030] The following is a detailed description of a secondary clamping fixture for preventing track fasteners from bouncing, provided by this utility model, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are listed as best and preferred embodiments; other alternative methods may be used by those skilled in the art. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0031] like Figure 1 and Figure 5 As shown, an embodiment of the present invention provides a secondary clamping clamp to prevent track fasteners from bouncing, comprising: a base 1, a fixing component 2 and an elastic component 3 respectively provided on the top of the base 1, and a rail 4 tightly attached to the top of the elastic component 3;

[0032] The fixing component 2 includes a fixing frame 201. The top of the fixing frame 201 is provided with an adjusting screw 202. The bottom end of the adjusting screw 202 is rotatably connected to a lifting plate 205. The outer wall of the fixing frame 201 is provided with a limiting groove 206. The inner wall of the limiting groove 206 is provided with a through groove 207. The outer wall of the lifting plate 205 is fixedly fitted with a connecting plate 208. The end of the connecting plate 208 is fixedly fitted with a clamping plate 209. The outer wall of the clamping plate 209 is provided with a slot 210. The inner wall of the slot 210 is inserted with a first insert plate 213. The outer wall of the first insert plate 213 is fixedly fitted with a first locking rod 211. The top of the clamping plate 209 is provided with a connecting screw 212. The inner wall of the slot 210 can also be inserted with a second insert plate 214. The outer wall of the second insert plate 214 is fixedly fitted with a second locking rod 215. The outer wall of the adjusting screw 202 is threadedly connected with a first adjusting nut 203 and a second adjusting nut 204 respectively.

[0033] The elastic component 3 includes an elastic pad 301, with an iron pad 302 tightly attached to the top of the elastic pad 301, and a rail pad 303 tightly attached to the top of the iron pad 302. Fastening bolts 304 are provided on the tops of the elastic pad 301, iron pad 302, and rail pad 303. Through the structure of the base 1, fixing component 2, fixing frame 201, adjusting screw 202, first adjusting nut 203, second adjusting nut 204, lifting plate 205, and limiting groove 206, the user can rotate the first adjusting nut 203 and the second adjusting nut 204 during use, allowing the adjusting screw 202 to move the lifting plate 205 up and down. This ensures that when rails 4 made of different materials are supported by different numbers of elastic components, and the thickness is inconsistent, the user can flexibly adjust the height of the lifting plate 205 and the first locking rod 211 to achieve the effect of positioning the elastic components, thereby preventing the rail fasteners from bouncing and improving the applicability of the clamp.

[0034] like Figure 1 and Figure 2 The number of fixing frames 201 shown is two, and both fixing frames 201 are symmetrically distributed along the top of the base 1, which is made of concrete. By setting two fixing frames 201, the clamps on both sides can ensure that the elastic parts on both sides of the track will not bounce during use, thereby ensuring that the track will not loosen or even shift in position during use, thus improving the stability of the track during operation and ensuring the normal use of the clamp.

[0035] like Figure 2 and Figure 3 The top of the fixed frame 201 shown has a through hole, and the inner wall of the through hole is slidably connected to the outer wall of the adjusting screw 202. Through the through hole and the adjusting screw 202 structure, the clamp can raise and lower the lifting plate 205 by utilizing the adjustable characteristic of the adjusting screw 202 during operation. During operation, the user can only release or lock the adjusting screw 202 by rotating the first adjusting nut 203 and the second adjusting nut 204, which avoids the adjusting screw 202 from loosening due to external interference after adjustment, and further improves the stability of the clamp.

[0036] like Figure 2 and Figure 3 The fixed frame 201 shown is fixedly equipped with support frames on both sides, and the support frames, fixed frame 201 and base 1 form a triangular structure. Through the support frame structure, when the track is compressed during use, the clamp will apply a squeezing force to both sides, thereby using the triangular structure between the support frame, fixed frame 201 and base 1 to prevent the three from shifting positions, thus ensuring that the use of the clamp will not be affected and improving the tightness of the connection structure between the components of the clamp.

[0037] like Figure 1 and Figure 5 The elastic pad 301, iron pad 302, and rail pad 303 shown all have round holes on their tops, and the inner walls of the round holes are threaded to the outer walls of the fastening bolts 304. Through the round hole structure, the user can complete the installation of the rail 4 using conventional installation methods during the use of the clamp, so that the elastic component 3 can provide shock absorption for the rail 4, thereby ensuring that the installation of the clamp will not affect the stability of the original structure.

[0038] like Figure 2 and Figure 4The bottom of the first adjusting nut 203 is tightly fitted with the top of the fixing frame 201, and the top of the second adjusting nut 204 is tightly fitted with the bottom of the fixing frame 201. The adjusting screw 202 is fixedly connected to the fixing frame 201 through the first adjusting nut 203 and the second adjusting nut 204 respectively. With the structure of the fixing frame 201 and the first adjusting nut 203, after the clamp is installed, the user can adjust the height of the lifting plate 205 by rotating the first adjusting nut 203 and the second adjusting nut 204 on both sides of the fixing frame 201. This makes it convenient for the user to operate, reduces the difficulty of operating the clamp, and improves the practicality of the clamp.

[0039] like Figure 3 and Figure 5 The clamping plate 209 and the first insert plate 213 shown both have fixing holes at their tops, and the inner walls of the fixing holes are threadedly connected to the outer walls of the connecting screw 212. Through the fixing holes and the connecting screw 212 structure, the clamp allows the user to easily disassemble and assemble the first clamp rod 211 and the first insert plate 213 by rotating the connecting screw 212 during use. This ensures that when installing rails 4 of different sizes, the first insert plate 213 and the first clamp rod 211 can be replaced with the second insert plate 214 and the second clamp rod 215, ensuring that the clamp is suitable for the installation of rails of different sizes, thus facilitating user operation and further improving the practicality of the clamp.

[0040] like Figure 3 and Figure 5 The outer wall of the connecting plate 208 shown is slidably connected to the inner wall of the through groove 207, and both the lifting plate 205 and the connecting plate 208 are made of galvanized iron. Galvanized iron has the characteristics of hardness and wear resistance, which can effectively reduce the wear of both during operation, thereby extending their service life. Galvanized iron also has the characteristic of low cost, thereby reducing the production and maintenance costs of the fixture.

[0041] Working principle: First, when installing the clamp, the user can first separate the first adjusting nut 203 and the second adjusting nut 204 from the fixed frame 201 by rotating them. This allows the user to adjust the adjusting screw 202 to raise and lower the lifting plate 205. Then, the user can retighten the first adjusting nut 203 and the second adjusting nut 204 so that they are both in contact with the outer wall of the fixed frame 201. This allows the user to install rails 4 made of different materials, which may have different numbers of elastic components 3, resulting in different thicknesses of the elastic components 3. At this time, the positioning operation of the elastic component 3 can also be completed by the clamp, thereby ensuring the positioning effect of the clamp on the elastic component 3, improving the applicability of the clamp. In addition, during the operation, the user can also replace the first insert plate 213 and the first clamp rod 211 with the second insert plate 214 and the second clamp rod 215 by removing the connecting screw 212, avoiding the first clamp rod 211 being too thick and causing the clamp to be unable to be installed normally. This makes it easier for the user to replace the components in the clamp, thereby facilitating the user's operation and improving the practicality of the clamp.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
