Description

Technical Field

[0001] This utility model belongs to the technical field of track vibration reduction, specifically relating to a track vibration reduction device for mine transportation. Background Technology

[0002] During rail transportation, especially in mining rail systems, the heavy loads and strong vibrations cause accelerated wear, loosening, and even deformation of the rails after prolonged use. To reduce vibration, existing technologies typically install shock-absorbing components such as damping pads and spring dampers at the bottom of the rail. These components are fixed to the bottom of the rail using bolts or welding, making disassembly and replacement extremely difficult due to the existing connection structure. Furthermore, the shock-absorbing components themselves are exposed to prolonged vibration, causing the connection between the components and the rail to loosen over time, ultimately rendering the mining rail unusable.

[0003] Based on the problems existing in the prior art, this utility model discloses a track vibration damping device for mine transportation. Utility Model Content

[0004] This utility model discloses a track vibration damping device for mine transportation, which can be conveniently and efficiently installed and disassembled with the track. At the same time, it can lock and reinforce the connection structure between the vibration damping component and the track to prevent the track and vibration damping component from loosening under long-term vibration.

[0005] This utility model is achieved through the following technical solution:

[0006] A track vibration damping device for mine transportation includes a track body and a vibration damping component. The bottom of the track body is provided with a storage groove, and the top of the vibration damping component is provided with a support member that extends into the storage groove and is slidably engaged with the storage groove. A first locking member is provided on one side of the vibration damping component, and the locking end of the first locking member extends to one side of the support member and locks the support member. A second locking member is provided at the end of the first locking member away from the vibration damping component, and the locking end of the second locking member extends to one side of the first locking member and locks the first locking member.

[0007] When the track body is subjected to vibration, the vibration is transmitted to the support member through the receiving groove, and then to the damping component through the support member to achieve vibration damping. At the same time, the first locking member engages or abuts one side of the support member to fix it in place and prevent it from loosening. The second locking member locks the first locking member, thus preventing it from loosening and ensuring a stable locking connection between the first locking member and the support member, forming a double locking structure. Ultimately, this ensures that the entire damping device not only effectively buffers vibration but also prevents it from loosening or detaching even when subjected to vibration for extended periods.

[0008] To better realize this utility model, the first locking member further includes a support frame and a locking screw. The support frame is fixedly disposed on the side of the shock absorption assembly. The locking screw is installed in the internal thread of the support frame. One end of the locking screw is engaged or abutted against one side of the support member.

[0009] To better realize this utility model, the second locking member further includes a fixing plate, a limiting rod, and a turntable. The fixing plate is disposed on one side of the support frame. The turntable is sleeved on the outside of the locking screw and rotates synchronously with the locking screw. The limiting rod is slidably disposed on the fixing plate toward the turntable. A plurality of locking holes are provided circumferentially on the outer side of the turntable. One end of the limiting rod is inserted into the corresponding locking hole.

[0010] To better realize this utility model, the second locking member further includes a tension spring, which is sleeved on the outside of the limiting rod and is compressed or stretched as the limiting rod slides.

[0011] To better realize this utility model, the storage groove is further provided with a linear storage hole on the groove wall, and a third locking member is provided inside the storage hole. The third locking member engages or disengages with the locking hole on the side of the support member as the support member slides.

[0012] To better realize this utility model, the third locking member further includes a limiting pin and a spring. The limiting pin is slidably disposed inside the storage hole. A spring is provided between the end of the limiting pin inside the storage hole and the bottom of the storage hole. The end of the limiting pin outside the storage hole is engaged with a locking hole on the side of the support member.

[0013] To better realize this utility model, the support member further includes a sliding support frame and a support bar. The sliding support frame is slidably fitted inside the storage groove. The side of the sliding support frame is provided with a locking hole that corresponds to the third locking member. The bottom of the sliding support frame is provided with a support bar. The bottom of the support bar is connected to the top of the shock absorption component. One side of the support bar is connected to the locking end of the first locking member.

[0014] To better realize this utility model, the shock absorption assembly further includes a support plate, shock absorbers, and shock absorption blocks. The top of the support plate is provided with a plurality of mounting holes, and support members are installed inside the mounting holes. The bottom of the support plate is provided with a plurality of shock absorbers, and shock absorption blocks are provided at the bottom of the shock absorbers.

[0015] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0016] (1) This utility model achieves sliding engagement between the support member on the top of the shock absorber and the storage groove at the bottom of the track body by setting a support member. Only the sliding support member is needed to achieve convenient connection or disassembly between the track body and the shock absorber, making the maintenance and replacement of the shock absorber more convenient and faster.

[0017] (2) This utility model provides a first locking member on one side of the support member to lock the support member, thereby ensuring a stable connection between the support member and the track body and avoiding the problem of the track body and the support member becoming loose and falling off due to long-term use in a vibration environment. At the same time, this utility model also provides a second locking member to lock the first locking member, thereby ensuring that the first locking member is securely locked to the support member and avoiding the problem of the first locking member itself becoming loose due to long-term use in a vibration environment. Ultimately, this utility model ensures that the entire shock absorption device can work stably in a vibration environment for a long time. Attached Figure Description

Detailed Implementation

[0024] Example 1:

[0025] This embodiment provides a track vibration damping device for mine transportation, such as... Figures 1-3 As shown, the device includes a track body 100 and a shock-absorbing assembly. The bottom of the track body 100 is provided with a storage groove 200. The top of the shock-absorbing assembly is provided with a support member that extends into the storage groove 200 and slides and engages with the storage groove 200. A first locking member is provided on one side of the shock-absorbing assembly. The locking end of the first locking member extends to one side of the support member and locks the support member. A second locking member is provided at the end of the first locking member away from the shock-absorbing assembly. The locking end of the second locking member extends to one side of the first locking member and locks the first locking member.

[0026] like Figure 1 As shown, two storage slots 200 are symmetrically arranged on the left and right sides of the bottom of the track body 1 about the center plane. Support members are provided on the top of the shock-absorbing component on the left and right sides, corresponding to the two storage slots 200 respectively. The top of the support member extends into the interior of the storage slot 200 and slides into or out of the slot wall. When the support member slides into the slot wall, the track body 100, support member, and shock-absorbing component are connected. Vibration is transmitted from the track body 100 and support member to the shock-absorbing component, which buffers and weakens the vibration. When the support member slides out of the slot wall, the track body 100 can be easily disassembled from above the shock-absorbing component, making the connection between the track body 100 and the shock-absorbing component more convenient.

[0027] A first locking member is provided on one side of the shock-absorbing component. The locking end of the first locking member extends towards the support member and is locked to one side of the support member. The first locking member provides a primary lock to the support member, ensuring the stability of the connection between the support member and the storage groove 200 and preventing the support member from loosening or falling out of the storage groove 200 in a long-term vibration environment. At the same time, to ensure the stability of the first locking member, a second locking member is provided on one side of the first locking member. The second locking member is used to lock the state of the first locking member, ensuring a stable locked connection between the first locking member and the support member. The second locking member constitutes a secondary lock, thereby ensuring the stability of the entire shock-absorbing device.

[0028] Example 2:

[0029] This embodiment is a further optimization based on Embodiment 1, such as... Figure 1 and Figure 4As shown, the first locking component includes a support frame 501 and a locking screw 502. The support frame 501 is fixedly disposed on the side of the shock absorption component. The locking screw 502 is installed in the internal thread of the support frame 501. One end of the locking screw 502 is engaged or abutted against one side of the support component.

[0030] Both the support frame 501 and the shock-absorbing component have threaded holes on their side walls. The locking screw 502 is threaded into these holes. By rotating the locking screw 502, one end of the screw extends to one side of the support and engages or abuts against it. Alternatively, a locking hole can be provided on the side of the support, allowing one end of the locking screw 502 to engage with it, thus locking the support and ensuring a secure connection between the locking component and the storage slot 200.

[0031] The other parts of this embodiment are the same as those in Embodiment 1, so they will not be described again.

[0032] Example 3:

[0033] This embodiment is a further optimization based on the above embodiment 1 or 2, such as... Figure 4 As shown, the second locking component includes a fixing plate 701, a limiting rod 702, and a turntable 703. The fixing plate 701 is disposed on one side of the support frame 501. The turntable 703 is sleeved on the outside of the locking screw 502 and rotates synchronously with the locking screw 502. The limiting rod 702 is slidably disposed on the fixing plate 701 facing the turntable 703. The outer surface of the turntable 703 is provided with a plurality of locking holes circumferentially. One end of the limiting rod 702 is inserted into a corresponding locking hole.

[0034] The fixed plate 701 has mounting holes, and a limit rod 702 is slidably fitted inside the mounting holes. The turntable 703 is sleeved on the outside of the locking screw 502 and rotates synchronously with the locking screw 502. Several locking holes are evenly distributed circumferentially on the outer surface of the turntable 703. When it is necessary to lock the locking screw 502, the limit rod 702 is slid along the locking hole on the outer surface of the turntable 703, so that one end of the limit rod 702 is inserted into the locking hole, thereby locking the turntable 703 through the limit rod 702. At this time, the locking screw 502 can no longer rotate, thus locking the locking screw 502.

[0035] Furthermore, the second locking component also includes a tension spring 704, which is sleeved on the outside of the limiting rod 702 and compresses or stretches as the limiting rod 702 slides. The tension spring 704 is located between the fixing plate 701 and the end of the limiting rod 702 away from the turntable 703, and the tension spring 704 is normally in a taut state. The tension spring 704 provides a pulling force to the limiting rod 702 toward the locking hole, ensuring that the limiting rod 702 can be stably inserted into the locking hole under the elastic force of the tension spring 704.

[0036] The other parts of this embodiment are the same as those in Embodiment 1 or 2 above, so they will not be described again.

[0037] Example 4:

[0038] This embodiment is a further optimization based on any one of embodiments 1-3 above, such as... Figure 5 As shown, the storage groove 200 has linearly arranged storage holes 601 on its groove wall. A third locking member is disposed inside the storage hole 601. The third locking member engages or disengages with a locking hole on the side of the support member as the support member slides. When the support member slides to a position where its locking hole aligns with the third locking member, one end of the third locking member enters and engages with the locking hole, thus locking the support member. When the support member slides to a position where its locking hole and the third locking member are not aligned, one end of the third locking member disengages from the locking hole, allowing for quick disassembly between the track body 100 and the support member.

[0039] Furthermore, the third locking component includes a limiting pin 602 and a spring 603. The limiting pin 602 is slidably disposed inside the receiving hole 601. A spring 603 is disposed between the end of the limiting pin 602 inside the receiving hole 601 and the bottom of the receiving hole 601. The end of the limiting pin 602 outside the receiving hole 601 is engaged with a locking hole on the side of the support component.

[0040] When the support slides to the position where its locking hole aligns with the third locking member, the limiting pin 602, under the elastic force of the spring 063, enters the locking hole and engages with it, thus locking the support. At this point, the track body 100 and the support are securely connected. When the support slides to the point where its locking hole is misaligned with the limiting pin 602, the spring 603 is compressed, and the limiting pin 602 disengages from the locking hole, allowing for quick disassembly between the track body 100 and the support.

[0041] The other parts of this embodiment are the same as any one of the embodiments 1-3 above, so they will not be described again.

[0042] Example 5:

[0043] This embodiment is a further optimization based on any one of embodiments 1-4 above, such as... Figure 1 As shown, the support includes a sliding support frame 300 and a support bar 301. The sliding support frame 300 is slidably fitted inside the storage groove 200. The side of the sliding support frame 300 is provided with a locking hole that corresponds to the third locking member. The bottom of the sliding support frame 300 is provided with a support bar 301. The bottom of the support bar 301 is connected to the top of the shock absorption component. One side of the support bar 301 is connected to the locking end of the first locking member.

[0044] The sliding support frame 300 is shaped like an inverted "U," ensuring that its top surface and both sides slide smoothly into the storage groove 200, allowing it to slide smoothly along the groove. Locking holes are provided on the left and right sides of the sliding support frame 300 corresponding to the limiting posts 602, enabling quick engagement and disengagement between the sliding support frame 300 and the limiting posts 602. A support strip 301 is connected to the bottom of the sliding support frame 300. The bottom of the support strip 301 is fixed to the top of the shock-absorbing component. Locking holes or grooves are provided on the sides of the support strip 301 corresponding to the locking end of the first locking member, enabling a locking connection between the support strip 301 and the first locking member.

[0045] The other parts of this embodiment are the same as any one of the embodiments 1-4 above, so they will not be described again.

[0046] Example 6:

[0047] This embodiment is a further optimization based on any one of embodiments 1-5 above, such as... Figure 1 and Figure 2 As shown, the shock absorption assembly includes a support plate 401, shock absorbers 402, and shock absorber blocks 403. The top of the support plate 401 is provided with a plurality of mounting holes, and support members are installed inside the mounting holes. The bottom of the support plate 401 is provided with a plurality of shock absorbers 402, and the bottom of the shock absorbers 402 is provided with shock absorber blocks 403.

[0048] When the track body 100 is subjected to vibration, the vibration is transmitted to the support member through the storage groove 200 at the bottom of the track body 100, and then to the support plate 401 through the support member. The support plate 401 supports the track body 100 and transmits the vibration to the shock absorber 402. The shock absorber 402 buffers and weakens the vibration. At the same time, the shock absorber block 403 is leveled and placed on the ground as a base to ensure the stable installation of the shock absorber 402 and the support plate 401.

[0049] The other parts of this embodiment are the same as any one of the embodiments 1-5 above, so they will not be described again.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
