Description

Technical Field

[0001] This utility model relates to the field of nut technology, and in particular to a secondary reinforcement device for preventing nut loosening. Background Technology

[0002] A nut is a threaded fastener, typically used in conjunction with a bolt or threaded rod, to fasten two or more components together. It is an indispensable basic component in machinery, construction, automotive, and aerospace industries. Structurally, the basic form of a nut is a cylindrical or hexagonal geometric shape with internal threads. The specification of the internal thread must match the corresponding external thread of the bolt. Connection and fastening are achieved through the meshing of the threads. Nuts are made of various materials, commonly including carbon steel, stainless steel, and copper. Different materials are suitable for different working environments. Nuts come in many types, and according to their uses and structures, they can be divided into hexagonal nuts, square nuts, round nuts, and wing nuts. Among them, hexagonal nuts are the most widely used due to their ease of wrench operation; wing nuts can be tightened by hand without tools and are often used in situations requiring frequent disassembly. On important equipment, secondary or even multiple tightening is performed to ensure the nuts are secure.

[0003] In daily construction and manufacturing processes, especially in the bolt reinforcement of subway, train, and high-speed rail tracks, bolts are often tightened manually by screwing them in. This manual operation can lead to inconsistent tightening, resulting in incomplete tightening. Incompletely tightened bolts can cause serious safety accidents while trains are in motion. By designing a secondary tightening device, after the initial tightening of the nuts, a second tightening is performed using the device. Through motor control, this automatic secondary tightening is achieved, significantly reducing safety risks and labor costs. However, due to the device's large size and weight, manual handling over long construction lines would consume considerable time and increase costs, severely hindering construction. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a secondary tightening device for preventing loosening of nuts, which aims to improve the problem that in the existing technology, manual operation can result in different degrees of tightening and incomplete tightening.

Stabilizing blocks 13 are fixedly connected to the left and right sides of the main platform 1. The rotating column 5 passes through the inside of the stabilizing block 13. A sliding groove 21 is opened at the bottom of the lifting platform 3. The sliding groove 21 is used for the sliding of the sliding block 12.

[0036] Specifically, hollow columns 20 are fixedly connected to the left and right ends of the top of the main platform 1, while solid columns 19 are fixedly connected to the left and right ends of the bottom of the lifting platform 3. The solid columns 19 and hollow columns 20 cooperate with each other to ensure that the lifting platform 3 remains stable during the lifting process and avoids shaking.

The function of the support block 17 is to support the rear end of the screw 8 and ensure the stability of the screw 8 during the lifting operation. A sliding groove 18 is provided on the top of the main platform 1. The sliding groove 18 is specifically for the rotating rod 10 to slide in, ensuring that the movement trajectory of the rotating rod 10 conforms to the design idea. Stabilizing blocks 13 are fixedly connected to the left and right sides of the main platform 1. The rotating column 5 passes through the inside of the stabilizing block 13, which further enhances the stability of the rotating column 5.

[0038] Specifically, a fixing block 24 is fixedly connected to the bottom of the main platform 1. The function of the fixing block 24 is to fix and support the moving motor 22. The moving motor 22 is the power source for the movement of the entire device, providing strong power support. A connecting column 23 is fixedly connected to the output end of the moving motor 22. A longitudinal bevel gear 16 is fixedly connected to the front end of the connecting column 23. A transverse bevel gear 15 is fixedly connected to the middle of the outer wall of the support column 203. The transverse bevel gear 15 and the longitudinal bevel gear 16 cooperate with each other to transmit the rotational power vertically, ensuring the movement of the device on the track. An anti-slip pad 14 is fixedly connected to the outer wall of the roller 205. The design of the anti-slip pad 14 effectively increases the friction between the roller 205 and the track, preventing the device from slipping during movement and further improving the stability and safety of the device.

[0039] Working principle: Start the screw motors 4 on both sides of the lifting platform 3. The screw motors 4 drive the rotating column 5 to rotate, which in turn drives the tightening block 6 to rotate. The tightening block 6 then drives the bolts on the side of the track to rotate, continuously tightening the bolts. After tightening is complete, start the lifting motor 11. The lifting motor 11 drives the screw 8 to rotate. Since the screw 8 and the rotating rod 10 are threadedly connected, the rotating rod 10 moves backward along the inner wall of the slide groove 18 as the screw 8 rotates. Because the top of the support rod 2 9 is connected to the rear of the lifting platform 3, the... Support rod 29 rotates continuously as rotating rod 10 moves backward. Support rod 29 drives sliding block 12 to move along the inner wall of slide groove 21. Since the middle part of support rod 29 and the middle part of support rod 17 are rotatably connected, and the bottom end of support rod 17 is rotatably connected to main platform 1, support rod 17 rotates with support rod 29. As support rod 17 and support rod 29 rotate, lifting platform 3 is continuously raised. Lifting platform 3 drives screw motor 4 to move upward, eventually lifting the tightening device away from the bolt.

[0040] The mobile motor 22 is started, which drives the connecting column 23 to rotate. The connecting column 23 drives the longitudinal bevel gear 16 to rotate. Due to the meshing characteristics of the transverse bevel gear 15 and the longitudinal bevel gear 16, the transverse bevel gear 15 rotates along with the longitudinal bevel gear 16. The transverse bevel gear 15 drives the support column 203 to rotate, which in turn drives the roller 205 to rotate, causing the roller 205 to roll along the track. Due to the special design of the roller 205, its shape prevents it from slipping off the track. When vibration occurs, the entire device will be squeezed downwards. The main platform 1 pushes the solid block 201 downward along the inner wall of the hollow block 204. The main platform 1 and the connecting block 206 compress the spring 202, and the solid block 201 compresses the air inside the hollow block 204, so that the air inside the hollow block 204 is continuously squeezed out from the holes on the hollow block 204. The downward pressure is offset by the air pressure formed by the slow flow of air and the elastic force of the spring 202. When the main platform 1 moves the solid block 201 upward, the upward speed of the solid block 201 is continuously reduced because the air enters the hollow block 204 slowly.
