[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0032] Example 1, by Figures 1-9 The present invention includes a housing 1 and a housing 3, a fixing mechanism 5 connecting the housing 1 and the housing 3, a monitoring mechanism 2 installed inside the housing 1 and the housing 3, and an adjustment mechanism 4 installed on the monitoring mechanism 2.
[0033] In Example 2, based on Example 1, the monitoring mechanism 2 includes an outer ring 201 located inside the housing 1, and an outer ring 202 located inside the housing 3. The outer ring 202 fits against the outer ring 1 201. Both the outer ring 1 201 and the outer ring 202 have fixing rings 205 on their outer sides. Pressure sensors 204 are installed at equal angles inside the two fixing rings 205. A network transmission device is electrically connected to the pressure sensors 204, and a data management platform is electrically connected to the network transmission device. The two fixing rings 205 are fixed inside the housing 1 and housing 3 respectively. Two screws 2014 are symmetrically fixed on the outer ring 202. A mounting plate 2012 is movably sleeved on the outer side of each screw 2014. Two insertion rods 2016 are symmetrically fixed on the side of the mounting plate 2012 closest to the outer ring 202. The outer ring 202 and the outer ring 1 202... Two insertion holes 2015 are symmetrically provided on the 01. Insertion rod 2016 is located inside the insertion hole 2015. Nut 2013 is provided on the side of the mounting plate 2012 away from the outer ring 202. Nut 2013 is threadedly connected to screw 2014. U-shaped plate 203 is fixedly installed inside the housing 1 and housing 23. Connecting shaft 207 is fixedly installed inside the U-shaped plate 203. Movable cylinder 206 is rotatably connected to the outside of the connecting shaft 207. Two sleeves 208 are symmetrically fixedly installed on the upper part of the movable cylinder 206. Movable rod 2011 is movably sleeved inside the sleeve 208. Movable cylinder 209 is fixedly installed at the end of the movable rod 2011 away from the movable cylinder 206. Two U-shaped rods 2010 are symmetrically fixedly installed on the outer sides of the outer ring 201 and outer ring 202. Movable cylinder 209 is rotatably sleeved on the outside of the U-shaped rod 2010.
[0034] First, outer ring 1 201 and outer ring 2 202 are fitted onto the contact wire. Then, two mounting plates 2012 are respectively fitted onto two screws 1 2014, with the insertion rod 2016 located inside the insertion hole 2015. The two mounting plates 2012 are then fixed with two nuts 1 2013, and outer ring 1 201 and outer ring 2 202 are also fixed. When the contact wire vibrates, it causes outer ring 1 201 and outer ring 2 202 to move and collide with pressure sensor 204. At this time, pressure sensor 204 monitors the index data reflecting the safety status of the contact network in real time and transmits the monitoring data to the data management platform through network transmission equipment. This allows staff to directly judge the safety status of the contact network through the data received by the data management platform without having to conduct on-site inspections by manual patrol.
[0035] In Example 3, based on Example 1, the adjusting mechanism 4 includes two mounting frames 401 symmetrically fixed inside outer ring 1 201 and outer ring 2 202. Two clamping plates 4012 are symmetrically arranged between the two mounting frames 401. Four limiting rods 402 are fixedly connected to the side of the clamping plate 4012 near the mounting frame 401. The end of the limiting rod 402 away from the clamping plate 4012 extends into the interior of the mounting frame 401 and is fixedly mounted with a limiting block 404. The limiting rod 402 is movably connected to the mounting frame 401. A guide rod 406 is fixedly installed inside the mounting frame 401. Two guide blocks 409 are symmetrically and movably sleeved on the outer side of the guide rod 406. A slider 4010 is fixedly installed on the side of each guide block 409 near the clamping plate 4012. A drive rod 4013 is rotatably connected to the side of each slider 4010 near the clamping plate 4012. The end of each drive rod 4013 away from the guide rod 406 is rotatably connected to the clamping plate 4012. The mounting frame 401 has a groove 4011 on the side near the clamping plate 4012. Both sliders 4010 are slidably connected to the groove 4011. The mounting frame 401 has a double-acting screw 405 inside. One end of the double-acting screw 405 is rotatably connected to the inner wall of the mounting frame 401, and the other end of the double-acting screw 405 passes through the mounting frame 401 and is fixedly mounted with a rotating disk 403. Two threaded sleeves 407 are symmetrically threaded on the outer side of the double-acting screw 405. All are located inside the mounting frame 401. Connecting posts 408 are fixedly connected between the two screw sleeves 407 and the two guide blocks 409. A fixing sleeve 4014 is fixedly installed on the outside of the mounting frame 401. The bidirectional screw 405 is rotatably sleeved inside the fixing sleeve 4014. The fixing sleeve 4014 has screw holes 4015 at equal angles on the side near the rotating disk 403. A bolt 4016 that matches the screw hole 4015 is installed between the rotating disk 403 and the fixing sleeve 4014.
[0036] First, the rotating disk 403 is rotated, which drives the bidirectional lead screw 405 to rotate and causes the two threaded sleeves 407 to move closer to each other. At the same time, the two connecting posts 408 drive the two guide blocks 409 to move closer to each other. At this time, the two sliders 4010 move closer to each other, and the two drive rods 4013 drive the clamping plate 4012 to move. Thus, the two clamping plates 4012 move closer to each other and clamp the thread. Then, the rotating disk 403 and the threaded hole 4015 are limited by the bolt 4016, so that the clamping of the thread is more stable.
[0037] In Example 4, based on Example 1, the fixing mechanism 5 includes two connecting plates 501 symmetrically fixed to the outside of the housing 1, and two connecting plates 502 symmetrically fixed to the outside of the housing 3. The two connecting plates 501 are respectively fitted to the two connecting plates 502. Both connecting plates 501 and 502 have T-slots 507, forming an I-shaped groove. A positioning post 505 is fixedly installed on the side of connecting plate 501 near the side of connecting plate 502. A positioning hole 506 is provided on the side of connecting plate 502 near the side of connecting plate 501, with the positioning post 505 located inside the positioning hole 506. A groove 504 is provided on the side of connecting plate 501 away from the positioning post 505, with the groove 504 containing... An inner rod 5010 is fixedly installed on the inner rod 5010. An inner block 508 is movably sleeved on the outer side of the inner rod 5010. A spring 509 is fixedly connected between the side of the inner block 508 away from the T-slot 507 and the groove 504. The spring 509 is movably sleeved with the inner rod 5010. A connecting rod 503 is fixedly installed on the side of the inner block 508 away from the positioning post 505. An I-shaped block 5011 is fixedly installed on the end of the connecting rod 503 away from the inner block 508. The I-shaped block 5011 is located inside the two T-slots 507. A screw rod 5013 is fixedly installed on the connecting plate 1 501. The connecting rod 503 is movably sleeved on the outer side of the screw rod 2 5013. A nut 2 5012 is provided on the connecting rod 503. The nut 2 5012 is threadedly sleeved with the screw rod 2 5013.
[0038] First, move the connecting rod 503, causing the inner block 508 to move along the inner rod 5010. At this time, the spring 509 is stretched. Then, the housing 1 and housing 2 are put together. At this time, the two connecting plates 1 and 2 are put together, and the two positioning pins 505 are located in the two positioning holes 506 respectively. Then, release the control of the connecting rod 503. At this time, the spring 509 returns to its original position, causing the inner block 508 to move and the connecting rod 503 to move until the I-shaped block 5011 enters the T-slot 507 of the connecting plate 1 and the connecting plate 2 502, connecting the connecting plate 1 and the connecting plate 2 502. At the same time, the connecting rod 503 is sleeved on the screw 2 5013. Then, the connecting rod 503 is fixed by the nut 2 5012, so that the connecting plate 1 and the connecting plate 2 502 are more firmly fixed. Finally, the installation of the entire device is completed.
