Description

Technical Field

[0001] This utility model relates to the field of railway turnout conversion force measurement technology, and in particular to a connecting rod assembly for measuring railway turnout conversion force. Background Technology

[0002] Railway turnout switching force measurement is a crucial step in ensuring the normal operation and safety of turnouts. It mainly involves the accurate monitoring and analysis of the force required during turnout switching. The railway turnout switching force measurement requires the use of a connecting rod assembly, which consists of a force sensor, a mechanical connection structure, and a built-in signal transmission module.

[0003] In the existing technology, the connection method of the connecting rod assembly is relatively complicated, making it difficult to quickly replace the spare rod when the connecting rod fails, and making emergency replacement difficult. Secondly, the mechanism of the connecting rod assembly is relatively fixed, making it difficult to adapt to different situations. Utility Model Content

[0004] The purpose of this utility model is to provide a connecting rod assembly for measuring the conversion force of railway turnouts, so as to solve the problems mentioned in the background art, which are that the connecting rod assembly has a complicated connection method, making it difficult to quickly replace the spare rod when the connecting rod fails, and making it difficult to carry out emergency replacement. Secondly, the connecting rod assembly has a relatively fixed mechanism, making it difficult to be applicable to different situations.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: It includes a connecting rod body, one end of which is provided with an adjustment mechanism. The adjustment mechanism includes a sleeve, an adjustment groove, a fixing groove, a solid rod, a first friction plate, a hydraulic cylinder, and a second friction plate. The other end of both the connecting rod body and the other end of the adjustment mechanism are provided with quick-release components. Each quick-release component includes a mounting block, a mounting groove, a locking groove, a insertion block, a spring groove, a moving groove, a connecting spring, a locking block, a moving plate, and a protrusion. One set of quick-release components has a U-shaped fork at its other end, and the other set of quick-release components has a universal joint at its other end.

[0006] In a preferred embodiment, one end of the connecting rod body is fixedly connected to one end of the sleeve, and an adjustment groove is provided inside the sleeve, with a fixing groove at the bottom of the adjustment groove.

[0007] In a preferred embodiment, the inner wall of the adjusting groove is movably connected to the outer wall of the solid rod, and the bottom of the solid rod is fixedly connected to the top of the first friction plate.

[0008] In a preferred embodiment, the inner wall of the fixing groove is fixedly connected to the outer wall of the hydraulic cylinder, and the top of the hydraulic cylinder is fixedly connected to the bottom of the second friction plate, while the top of the second friction plate is movably connected to the bottom of the first friction plate.

[0009] In a preferred embodiment, the mounting block has an internal mounting groove, and the inner wall of the mounting groove has a retaining groove, wherein the inner wall of the mounting groove is movably connected to the outer wall of the insertion block.

[0010] In a preferred embodiment, the insert has a spring groove inside, and a moving groove is formed on one side of the inner wall of the spring groove. The other end of the connecting rod body and one end of the solid rod are both fixedly connected to one end of the insert.

[0011] In a preferred embodiment, the inner wall of the spring groove is fixedly connected to one end of the connecting spring, and the other end of the connecting spring is fixedly connected to one end of the locking block. One side of the locking block is fixedly connected to one side of the moving plate, and the outer wall of the locking block is movably connected to the inner wall of the locking groove.

[0012] In a preferred embodiment, the top of the movable plate is fixedly connected to the bottom of the protrusion, and one end of each of the two sets of mounting blocks is fixedly connected to one end of the U-shaped fork and the universal joint, respectively.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the connecting rod body is first installed using a U-shaped fork and a universal joint. When the connecting rod body is replaced urgently, the pressing protrusion moves the moving plate inside the moving groove. The moving plate moves the locking block inside the spring groove, thereby causing the locking block to squeeze the connecting spring. At the same time, the locking block moves away from the inside of the locking groove, allowing the insert block to break free from the limiting state. Then, the new connecting rod body is installed into the mounting block through the insert block, which facilitates the disassembly and assembly of the mounting block and the insert block, thus facilitating the quick replacement of the connecting rod body.

[0015] 2. In this utility model, when the connecting rod body is installed, the solid rod is moved inside the adjustment groove at a distance. After installation, the hydraulic cylinder is activated to move the second friction plate upward, so that the second friction plate squeezes the bottom of the first friction plate, thereby locking the solid rod. The movement of the solid rod inside the adjustment groove increases the applicability of the device. Attached Figure Description

[0027] Specifically, it facilitates the adjustment of the overall length of the device, making it suitable for different situations.

[0028] In one embodiment, the inner wall of the adjusting groove 202 is movably connected to the outer wall of the solid rod 204, and the bottom of the solid rod 204 is fixedly connected to the top of the first friction plate 205.

[0029] Specifically, the device's applicability is increased by moving the solid rod 204 inside the adjusting groove 202.

[0030] In one embodiment, the inner wall of the fixing groove 203 is fixedly connected to the outer wall of the hydraulic cylinder 206, and the top of the hydraulic cylinder 206 is fixedly connected to the bottom of the second friction plate 207, while the top of the second friction plate 207 is movably connected to the bottom of the first friction plate 205.

[0031] Specifically: the second friction plate 207 presses against the bottom of the first friction plate 205, thereby locking the solid rod 204.

[0032] In one embodiment, the mounting block 301 has a mounting groove 302 inside, and the inner wall of the mounting groove 302 has a slot 303. The inner wall of the mounting groove 302 is movably connected to the outer wall of the insert block 304.

[0033] Specifically, it facilitates the installation and disassembly of mounting block 301 and insert block 304, thereby facilitating the quick replacement of the connecting rod body 1.

[0034] In one embodiment, the insert 304 has a spring groove 305 inside, and a moving groove 306 is provided on one side of the inner wall of the spring groove 305. The other end of the connecting rod body 1 and one end of the solid rod 204 are both fixedly connected to one end of the insert 304.

[0035] Specifically: the card block 308 moves away from the inside of the card slot 303, so that the insert block 304 is freed from the limiting state, and then the new connecting rod body 1 is installed into the inside of the mounting block 301 through the insert block 304.

[0036] In one embodiment, the inner wall of the spring groove 305 is fixedly connected to one end of the connecting spring 307, and the other end of the connecting spring 307 is fixedly connected to one end of the locking block 308.
