Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, specifically a reinforced rubber shock absorber for rail transit. Background Technology

[0002] With the rapid development of rail transit, higher requirements have been placed on the smoothness, comfort, and safety of train operation. Trains generate various vibrations during operation, such as vibrations from the contact between the wheels and the rails, and vibrations when the vehicle passes through curves or switches. These vibrations not only affect the passenger experience but also cause wear and damage to the train's equipment and track structure, shortening their service life.

[0003] Most currently used rubber shock absorbers cannot reinforce the frame. Without proper frame reinforcement, the unreinforced frame makes it difficult for the shock absorber to effectively absorb and buffer sudden impact loads, resulting in insufficient load-bearing capacity, increased risk of component damage, and potentially affecting vehicle safety. This leads to poor safety for the shock absorber. Furthermore, the inconvenience of installing and replacing rubber blocks makes the process cumbersome, reducing replacement efficiency and hindering subsequent work progress, thus diminishing the shock absorber's practicality. Utility Model Content

[0004] The purpose of this invention is to provide a reinforced rubber shock absorber for rail transit to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reinforced rubber shock absorber for rail transit, comprising a frame body and a connecting plate. A supporting reinforcement mechanism is provided on the outer wall of the frame body. The supporting reinforcement mechanism includes a support block. The support block is movably connected to the outer wall of the frame body. Stress holes are formed inside the support block. Mounting blocks are fixedly connected to both sides of the support block. First threaded holes are formed inside both the mounting blocks and the frame body. First bolts are threadedly connected to the inner walls of the first threaded holes. A mounting plate is fixedly connected to the bottom of the support block. Second threaded holes are formed inside both the mounting plate and the connecting plate. Second bolts are threadedly connected to the inner walls of the second threaded holes.

[0006] As a preferred technical solution, the number of support blocks is four, and the shape of the support blocks is triangular.

[0007] As a preferred technical solution, the number of mounting blocks is four sets, with two blocks in each set, and the contact surface between the mounting blocks and the frame body is an arc-shaped structure.

[0008] As a preferred technical solution, the number of the second threaded holes is four groups, with two in each group, and the two second threaded holes are symmetrically arranged with the vertical center line of the mounting plate as the axis of symmetry.

[0009] As a preferred technical solution, the bottom of the frame body is fixedly connected to the top of the connecting plate, a rubber block is movably connected inside the frame body, and a buffer rod is fixedly connected to the top of the rubber block.

[0010] As a preferred technical solution, the bottom of the connecting plate is provided with an installation and replacement mechanism, the installation and replacement mechanism includes a fixing plate, and the bottom of the connecting plate is movably connected to the fixing plate.

[0011] As a preferred technical solution, both the interior of the fixing plate and the interior of the connecting plate are provided with a third threaded hole, and the number of the third threaded holes is four.

[0012] As a preferred technical solution, the inner wall of the third threaded hole is threaded with a third bolt, and the shape and size of the third bolt match the shape and size of the third threaded hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of the support and reinforcement mechanism, can achieve the function of supporting and reinforcing the frame. During use, the support block is installed on the frame through the cooperation of the first threaded hole and the first bolt, and the cooperation of the second bolt and the second threaded hole. The support block supports and reinforces the frame, which can avoid the situation where the frame cannot be supported and reinforced, resulting in the rubber shock absorber being unable to effectively absorb and buffer sudden impact loads, causing insufficient load-bearing capacity of the frame, increasing the risk of component damage, and even affecting the operating safety of the vehicle. This ensures the safety of the rubber shock absorber during use.

[0015] 2. This utility model, through the setting of the installation and replacement mechanism, can facilitate the installation and replacement of rubber blocks. During use, the fixing plate is opened by the cooperation of the third threaded hole and the third bolt, and the rubber block is installed or replaced. This avoids the situation where the installation or replacement of rubber blocks is inconvenient, which would lead to a cumbersome process and poor replacement efficiency, thus affecting the progress of subsequent work and ensuring the practicality of the rubber shock absorber.

[0023] 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.

[0024] Example: Figure 1 and Figure 2 As shown, the present invention provides the following technical solution, including a frame body 1 and a connecting plate 4. The outer wall of the frame body 1 is provided with a support and reinforcement mechanism 2. The bottom of the frame body 1 is fixedly connected to the top of the connecting plate 4. A rubber block 5 is movably connected inside the frame body 1. A buffer rod 6 is fixedly connected to the top of the rubber block 5. An installation and replacement mechanism 3 is provided at the bottom of the connecting plate 4.

[0025] Specifically, when the rubber shock absorber is needed, the frame body 1 must first be reinforced using the support and reinforcement mechanism 2. Then, the rubber block 5 is installed and fixed inside the frame body 1, and the rubber shock absorber is installed and fixed in a specific position on the vehicle using the installation and replacement mechanism 3. The rubber block 5 is then installed and fixed inside the frame body 1, and the rubber shock absorber is installed and fixed in a specific position on the vehicle. The rubber shock absorber can then be used for shock absorption. When impacted, the buffer rod 6 will descend, and the rubber block 5 will buffer and absorb the impact force, thus completing the shock absorption work. After a period of use, the rubber block 5 needs to be replaced using the installation and replacement mechanism 3, thus completing the work.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a support and reinforcement mechanism 2 is provided on the outer wall of the frame body 1. The support and reinforcement mechanism 2 includes a support block 201. The support block 201 is movably connected to the outer wall of the frame body 1. Stress holes 202 are opened inside the support block 201. Mounting blocks 203 are fixedly connected to both sides of the support block 201. First threaded holes 204 are opened inside the mounting blocks 203 and inside the frame body 1. First bolts 205 are threadedly connected to the inner wall of the first threaded holes 204. A mounting plate is fixedly connected to the bottom of the support block 201. 206. The interior of the mounting plate 206 and the interior of the connecting plate 4 are provided with second threaded holes 207. The inner wall of the second threaded hole 207 is threaded with a second bolt 208. There are four support blocks 201, and the shape of the support blocks 201 is triangular. There are four sets of mounting blocks 203, with two in each set. The contact surface between the mounting block 203 and the frame body 1 is an arc-shaped structure. There are four sets of second threaded holes 207, with two in each set. The two second threaded holes 207 are symmetrically arranged with the vertical center line of the mounting plate 206 as the axis of symmetry.

[0027] Specifically, when the rubber shock absorber is needed, the frame body 1 needs to be strengthened first. At this time, the support block 201 is attached to the frame body 1, and then the first threaded hole 204 in the mounting block 203 is aligned with the first threaded hole 204 on the outer wall of the frame body 1. Then, the second threaded hole 207 in the mounting plate 206 is aligned with the second threaded hole 207 in the connecting plate 4. Then, the first bolt 205 is rotated and inserted into the first threaded hole 204, and the second bolt 208 is rotated and inserted into the second threaded hole 207. The support block 201 is fixed on the frame body 1. The frame body 1 is then strengthened by the support block 201, which increases the load-bearing capacity of the frame body 1. At the same time, the stress hole 202 can reduce the local stress peak and reduce the possibility of structural failure due to stress concentration, thereby completing the support strengthening work.

[0028] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the bottom of the connecting plate 4 is provided with an installation and replacement mechanism 3. The installation and replacement mechanism 3 includes a fixing plate 301. The bottom of the connecting plate 4 is movably connected to the fixing plate 301. The interior of the fixing plate 301 and the interior of the connecting plate 4 are provided with three threaded holes 302. There are four three threaded holes 302. The inner wall of the three threaded holes 302 is threaded with a third bolt 303. The shape and size of the third bolt 303 match the shape and size of the third threaded hole 302.

[0029] Specifically: When it is necessary to install and fix the rubber block 5 inside the frame body 1 and install and fix the rubber shock absorber at a specific position on the vehicle, the rubber block 5 is placed inside the frame body 1, then the fixing plate 301 covers the bottom of the connecting plate 4, and the bottom of the fixing plate 301 is aligned with the specific installation position. Then, the third threaded hole 302 in the fixing plate 301, the third threaded hole 302 in the connecting plate 4, and the third threaded hole 302 in the specific installation position are aligned. Then, the third bolt 303 is rotated and inserted into the third threaded hole 302 to fix the connecting plate 4 and the fixing plate 301. The fixing plate 301 is fixed to fix the rubber block 5 inside the frame body 1, and the rubber shock absorber is installed in a specific position, thus completing the installation work. After the rubber block 5 has been used for a period of time, it needs to be replaced. By cooperating with the third threaded hole 302 and the third bolt 303, the fixing plate 301 is removed from the bottom of the connecting plate 4, the old rubber block 5 is taken out, and the new rubber block 5 is put into the frame body 1. Then, by cooperating with the third threaded hole 302 and the third bolt 303, the fixing plate 301 is installed at the bottom of the connecting plate 4, thus completing the replacement work.

[0030] The working principle of this utility model is as follows: When the rubber shock absorber is needed, the frame body 1 needs to be strengthened first. At this time, the support block 201 is attached to the frame body 1. Then, the first threaded hole 204 in the mounting block 203 is aligned with the first threaded hole 204 on the outer wall of the frame body 1. Then, the second threaded hole 207 in the mounting plate 206 is aligned with the second threaded hole 207 in the connecting plate 4. Then, the first bolt 205 is rotated and inserted into the first threaded hole 204, and the second bolt 208 is rotated and inserted into the second threaded hole 207. The support block 201 is fixed to the frame body 1, thereby strengthening the frame body 1 and increasing its load-bearing capacity. Simultaneously, the stress hole 202 reduces local stress peaks, decreasing the possibility of structural failure due to stress concentration, thus completing the support reinforcement work. Next, the rubber block 5 needs to be installed and fixed inside the frame body 1, and the rubber shock absorber is installed and fixed at a specific position on the vehicle. At this point, the rubber block 5 is placed inside the frame body 1, and then the fixing plate 301 covers the bottom of the connecting plate 4. The bottom is fitted into a specific installation position. Then, the third threaded hole 302 in the fixing plate 301 and the third threaded hole 302 in the connecting plate 4 are aligned with the third threaded hole 302 in the specific installation position. Then, the third bolt 303 is rotated and inserted into the third threaded hole 302 to fix the connecting plate 4 and the fixing plate 301, so that the fixing plate 301 fixes the rubber block 5 inside the frame body 1. At the same time, the rubber shock absorber is installed in the specific position, thus completing the installation work. Then, the rubber shock absorber can be used for shock absorption. Upon impact, the buffer rod 6 will descend, and the rubber block 5 will buffer and dampen the impact force, thus completing the shock absorption work. After a period of use, the rubber block 5 needs to be replaced. By cooperating with the third threaded hole 302 and the third bolt 303, the fixing plate 301 is removed from the bottom of the connecting plate 4. Then, the old rubber block 5 is taken out, and the new rubber block 5 is put into the frame body 1. Then, by cooperating with the third threaded hole 302 and the third bolt 303, the fixing plate 301 is installed at the bottom of the connecting plate 4, thus completing the replacement work.
