Description

Technical Field

[0001] This utility model relates to the technical field of CRTSⅢ type slab track construction, and in particular to a rotatable track slab displacement monitoring device. Background Technology

[0002] CRTSⅢ type slab track has gradually replaced ballastless track due to its advantages such as good smoothness, high durability and low maintenance cost, becoming the main track structure in my country. During the construction of CRTSⅢ type slab track, a self-compacting concrete layer needs to be filled between the base plate and the track slab supported by the fine adjustment device. In order to control the elevation change of the track slab under the action of concrete during the pouring of self-compacting concrete, a clamping fixture is required to strictly control the floating displacement of the track slab. Currently widely used clamping fixtures have problems such as the inability to scientifically quantify the clamping force and uneven stress on the tie rods. After summarizing the technical difficulties of existing track slab clamping fixtures, a portal-type track slab clamping fixture was developed. In order to verify the application effect of the portal-type clamping fixture, a track slab displacement monitoring device is required for the process test of the track slab. Therefore, a rotatable track slab displacement monitoring device is particularly needed.

[0003] However, existing rotatable track slab displacement monitoring devices are mostly used for dynamic displacement monitoring of track slabs during operation, and cannot be directly applied to the process testing of clamping fixtures. At the same time, track slab displacement monitoring devices have problems such as difficulty in disassembly and low anti-interference ability. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 The present invention provides a technical solution: a rotatable track plate displacement monitoring device, including a base 1 and a combination mechanism 2, wherein the combination mechanism 2 is provided on one side of the surface of the base 1, and a detection mechanism 3 is provided at one end of the combination mechanism 2;

[0022] The combined mechanism 2 includes a first bolt 201, a base rod 202, an upper connecting rod 203, an outer clamping plate 204, a sliding groove 205, an integrated groove 206, a second bolt 207, a mounting plate 208, a partition plate 209, a spring 210, a slider 211, a connecting screw 212, and a fixing nut 213. The first bolt 201 is threaded onto one side of the base 1, and the base rod 202 is fixedly connected to one side of the base 1. The upper connecting rod 203 is attached to the other side of the base rod 202. The outer clamping plate 204 covers the upper edge of the base rod 202. A sliding groove 205 is provided on one side of the base rod 202, and a groove is provided at the bottom end of the upper connecting rod 203. The integrated groove 206 has a second bolt 207 threadedly connected to one end of the outer clamping plate 204. A mounting plate 208 is fixedly connected inside the sliding groove 205. A partition plate 209 is connected inside the integrated groove 206. A spring 210 is connected to one side of the mounting plate 208, and a slider 211 is connected to the other side of the spring 210. The other side of the slider 211 is in contact with the connecting screw 212. A fixing nut 213 is threadedly connected to the surface of the connecting screw 212. The system is connected via the first bolt 201, bottom rod 202, upper connecting rod 203, outer clamping plate 204, sliding groove 205, integrated groove 206, second bolt 207, and mounting plate 208. 08. The partition plate 209, spring 210, slider 211, connecting screw 212, and fixing nut 213 are configured as follows: In use, firstly, the base 1 is fixed in a suitable position using the first bolt 201. Then, the upper connecting rod 203 and the bottom rod 202 are engaged. At this time, the connecting screw 212 will pass through both sets of partition plates 209, and the upper connecting rod 203 is connected to the connecting screw 212 through the tight fit between the fixing nut 213 and the partition plate 209. Then, the connection between the bottom rod 202 and the upper connecting rod 203 is ensured by the tightening action of the outer clamping plate 204 and the second bolt 207. When needed... When the testing mechanism 3 is attached to the track plate, first loosen the second bolt 207, then pull the upper connecting rod 203. The upper connecting rod 203 drives the connecting screw 212 to move. The connecting screw 212 will press the slider 211 and cause the spring 210 to compress and deform. After moving to the appropriate position, the upper connecting rod 203 can be rotated. At this time, the bottom end of the connecting screw 212 will rotate relative to the slider 211 to ensure the normal rotation of the upper connecting rod 203. After the rotation is completed, put down the upper connecting rod 203. The bottom rod 202 and the upper connecting rod 203 can be fixed to each other again by the outer clamp 204 and the second bolt 207, and the testing can be carried out.

[0023] Furthermore, four sets of first bolts 201 are provided, and the four sets of first bolts 201 are symmetrically and equally spaced on the base 1. The base 1 is fixed to the ground by the first bolts 201. By setting the first bolts 201 at the four corners of the base 1, the base 1 is firmly fixed to the ground by the threaded connection, providing the basic stability of the overall device and ensuring the accuracy and reliability of the combined mechanism 2 and the detection mechanism 3 during monitoring.

[0024] Furthermore, the main body of the outer clamping plate 204 is sleeved at the connection between the bottom rod 202 and the upper connecting rod 203. The bottom rod 202 and the upper connecting rod 203 form a mutually fixed structure through the outer clamping plate 204 and the second bolt 207. With the setting of the outer clamping plate 204 and the second bolt 207, the outer clamping plate 204 is sleeved at the connection between the bottom rod 202 and the upper connecting rod 203, which plays the role of fixing and supporting the connection. The second bolt 207 passes through the outer clamping plate 204, so that the outer clamping plate 204 firmly clamps the bottom rod 202 and the upper connecting rod 203, forming a stable connection structure and preventing the connection from loosening.

[0025] Furthermore, one side of the connecting screw 212 passes through the mounting plate 208, the partition plate 209, and the slider 211 respectively. The connecting screw 212 forms a mutual sliding structure with the mounting plate 208 and the partition plate 209 through the spring 210 and the slider 211 respectively. With the setting of the connecting screw 212, the connecting screw 212 passes through the mounting plate 208, the partition plate 209, and the slider 211. As a key transmission element for sliding and connection, one end of it is in contact with the slider 211 and provides elastic adjustment capability through the spring 210. The other end is locked with the integrated groove 206 through the fixing nut 213, realizing the sliding and limit adjustment between the upper connecting rod 203 and the bottom rod 202, ensuring the stability and controllability of the combined mechanism 2 during displacement.

[0026] Furthermore, the main body of the spring 210 is sleeved on the connecting screw 212. The slider 211 forms a mutual sliding structure with the slide groove 205 through the spring 210. With the spring 210 sleeved on the connecting screw 212, it can be compressed or extended under the action of external force, so as to realize the elastic sliding of the slider 211 in the slide groove 205. Its main function is to provide buffering and rebound force, improve the relative sliding stability between the upper connecting rod 203 and the bottom rod 202, and enhance the impact resistance and adjustment flexibility of the combined mechanism 2.

[0027] Furthermore, the upper connecting rod 203 forms a sliding structure with the bottom rod 202 through the spring 210, the slider 211 and the connecting screw 212. The slider 211 slides synchronously with the connecting screw 212 through the spring 210. With the slider 211 set, the slider 211 is located in the slide groove 205, connected to the mounting plate 208 through the spring 210 and in contact with the connecting screw 212. Under the action of external force, it can slide along the slide groove 205 to realize the rotational adjustment between the upper connecting rod 203 and the bottom rod 202. It is an important sliding element for the combined mechanism 2 to realize elastic adjustment and positioning accuracy.

[0028] Furthermore, one side of the fixing nut 213 is attached to the partition plate 209, and the upper connecting rod 203 is fixed to the connecting screw 212 by the fixing nut 213. The main body of the fixing nut 213 is embedded in the integrated groove 206. Through the setting of the fixing nut 213, the fixing nut 213 is threadedly connected to the connecting screw 212, and one side of it is attached to the partition plate 209. This is used to lock the connecting screw 212 in the integrated groove 206, so as to achieve stable fixation between the upper connecting rod 203 and the connecting screw 212, and ensure the structural stability and adjustment reliability of the combined mechanism 2.

[0029] Furthermore, the detection mechanism 3 includes a magnetic support 301, a universal joint 302, a displacement micrometer 303, and a support platform 304. The magnetic support 301 is installed at the end of the upper connecting rod 203, and the universal joint 302 is installed at the bottom of the magnetic support 301. The displacement micrometer 303 is installed on the other side of the universal joint 302. The main body of the displacement micrometer 303 is placed on the support platform 304. Through the arrangement of the magnetic support 301, the universal joint 302, the displacement micrometer 303, and the support platform 304, the magnetic support 301 can be attracted to the metal surface for rapid positioning. At the same time, the universal joint 302 installed below provides multiple degrees of freedom for adjustment, making the detection direction flexible. Finally, the displacement micrometer 303 is installed at the end of the universal joint 302, which, together with the support platform 304, provides a stable contact base for the detection surface. The displacement micrometer 303 records the numerical changes to achieve accurate displacement detection and feedback.

[0030] Working principle: First, the base 1 is fixed in a suitable position by the first bolt 201. Then, the upper connecting rod 203 and the bottom rod 202 are engaged with each other. At this time, the connecting screw 212 will pass through the two sets of partition plates 209. Through the tight fit of the fixing nut 213 and the partition plate 209, the upper connecting rod 203 and the connecting screw 212 are connected. Then, through the tightening action of the outer clamping plate 204 and the second bolt 207, the connection between the bottom rod 202 and the upper connecting rod 203 is ensured to be stable. When it is necessary to fit the detection mechanism 3 with the track plate, first loosen the second bolt 207, and then pull the upper connecting rod 203. The upper connecting rod 203 drives the connecting screw 212 to move. The connecting screw 212 will press the slider 211, and cause the spring 210 to compress and deform, moving the slider 211. Once in the appropriate position, the upper connecting rod 203 can be rotated. At this time, the bottom end of the connecting screw 212 will rotate relative to the slider 211, ensuring the normal rotation of the upper connecting rod 203. After rotation, the upper connecting rod 203 is lowered, and the bottom rod 202 and the upper connecting rod 203 can be fixed together again by the outer clamp 204 and the second bolt 207, and the test can be performed. The magnetic support 301 can be attached to the metal surface to achieve rapid positioning. At the same time, the universal connecting rod 302 is installed below to provide multiple degrees of freedom for adjustment, making the test direction flexible. Finally, the displacement dial indicator 303 is installed at the end of the universal connecting rod 302, which, together with the support platform 304, provides a stable contact base for the test surface. The displacement dial indicator 303 records the numerical changes to achieve accurate displacement detection and feedback.
