Description

Technical Field

[0001] The present invention relates to the technical field of anti-collision equipment, and in particular to a bridge pier anti-collision fender and an installation method thereof. Background Art

[0002] At present, after the bridge piers are built, they span the waters, allowing ships to pass between them. However, ship-bridge collision accidents are still prone to occur. In order to protect personnel and reduce property losses as much as possible during the collision, it is necessary to improve the anti-collision performance of the fenders.

[0003] Generally, when surrounding the side of a bridge pier, the side made of elastic rubber is used to completely wrap the bridge pier or distribute it around the pier at intervals, and the main purpose is to optimize the fender material and structure.

[0004] Regarding the above-mentioned related technologies, the inventors found that after the anti-collision fenders were put on the bridge piers, since only the material and structure of the fenders were improved, the connection stability of the fenders under the traditional installation process was poor, resulting in a short service life of the fenders. Summary of the invention

[0005] Therefore, in order to increase the service life of the fender, the purpose of the present application is to provide a pier anti-collision fender and an installation method.

[0006] On the one hand, the present application provides a bridge pier anti-collision fender adopts the following technical solution:

[0007] A bridge pier anti-collision fender comprises a plurality of fixing plates arranged in the circumferential direction of the pier, a plurality of fixing rods penetrating the fixing plates and extending in the pier, and elastic buffer bodies arranged at the upper and lower ends of the fixing plates, wherein the buffer bodies are bent and arranged on the fixing plates, the fixing plates are provided with mounting grooves for the fixing rods to extend into, the mounting grooves are provided with reinforcing plates for the fixing rods to pass through, and one end of the fixing rods after passing through the fixing plates and the reinforcing plates is threadedly connected with a nut pressed against the reinforcing plate.

[0008] By adopting the above technical solution, when the anti-collision fender is installed on the bridge pier, the fixing plate is attached to the circumferential side wall of the bridge pier, and then the reinforcing plate is placed in the installation groove, so that the fixing rod is located in the installation groove after passing through the fixing plate and the reinforcing plate. Then the nut is threadedly connected to the end of the fixing rod in the installation groove, so that the reinforcing plate is pressed against the fixing plate, and the fixing plate is fixed to the circumferential side wall of the bridge pier. Then, the buffer body is distributed around the circumferential direction of the bridge pier to buffer the collision of the traveling ship with the bridge pier. Therefore, by placing the reinforcing plate in the installation groove, and fixing the fixing plate to the circumferential side wall of the bridge pier under the tightening of the nut, the fixing rod is connected to the bridge pier, and the reinforcing plate is pressed against the fixing plate, double reinforcement is achieved, and the stability of the connection between the fender and the bridge pier is strengthened, thereby increasing the service life of the fender.

[0009] Optionally, a connecting block is connected to one end of the buffer body close to the fixed plate, and the cross-sectional shape of the connecting block gradually expands in the direction away from the buffer body. The mounting groove passes through both sides of the fixed plate and is bent and opened on the fixed plate. The connecting block slides in the mounting groove, and the rotation of the buffer body can drive the connecting block to slide out of the mounting groove.

[0010] By adopting the above technical solution, when the buffer body is installed on the bridge pier, align the connecting block at the end of the buffer body with the installation groove, and then rotate the buffer body so that the connecting block slides into the installation groove and covers the nut. Then stretch the other buffer body, and slide the connecting block into the installation groove under the fixed plate by rotating it again. Until the upper and lower buffer bodies on the fixed plate abut against each other, so that when the hull hits the buffer body, the buffer bodies on the fixed plate will be dislocated from each other due to the different force magnitudes and directions of the buffer bodies on the fixed plate. While connecting the buffer body and the fixed plate through the connecting block, the buffer body is allowed to slide relative to each other, so that the relatively sliding buffer body further buffers the hull, thereby improving the buffering effect of the buffer body.

[0011] Optionally, a limit plate is provided between the buffer bodies, a positioning rod penetrated through the limit plate and arranged in the bridge pier, the positioning rod rotates in the limit plate, one end of the positioning rod passing through the limit plate is provided with a locking plate abutting against the limit plate, and a connecting groove for the limit plate to extend into and abut against is opened on the buffer body.

[0012] By adopting the above technical solution, after the buffer body is installed on the fixed plate, the buffer body is bent in the direction away from each other so that the buffer bodies abutting each other are away from each other. Then one end of the limit plate is first placed in the connecting groove, and then the positioning rod is inserted into the bridge pier after passing through the limit plate until the locking plate and the limit plate abut. The other end of the limit plate is placed in the connecting groove of another buffer body so that both ends of the limit plate are located in the connecting groove. Then, the two ends of the limit plate are pressed against the connecting groove to fix the inner side of the buffer body, thereby reducing the situation where the inner side of the buffer body is separated from the fixed plate after being squeezed.

[0013] When the hull hits the buffer body, the hull hits the buffer body and dislocation occurs, so that the two buffer bodies on the fixed plate are dislocated with each other, and the connecting block is driven to slide in the installation groove. Then the limit plate is driven to rotate on the positioning rod, and because the sliding of the buffer body is biased, after the hull is separated from the buffer body, the buffer body with a larger sliding distance will be pulled by the buffer body with a smaller sliding distance, and the rotation of the limit plate forms a traction force to reset the dislocated buffer body. Therefore, by setting the limit plate, the positioning rod and the locking plate, the locking plate and the positioning rod are used to press the limit plate tightly, and the inner side of the buffer body is pressed against the fixed plate, and the rotation of the limit plate on the positioning rod makes the interaction between the buffer bodies drive the dislocated buffer body to reset, so that the buffer body is automatically reset after being hit.

[0014] Optionally, an abutment column penetrating the connection block is provided in the connection groove, one end of the abutment column away from the connection block is penetrating the limit plate, and the abutment column rotates in the limit plate.

[0015] By adopting the above technical solution, when the buffer body is hit and dislocated, the buffer body drives the limit plate to rotate, and the limit plate and the abutment column rotate relative to each other, so that when the limit plate rotates in the connecting groove, it also acts on the buffer body through the abutment column, so that after the buffer bodies are dislocated from each other, the reaction force of the limit plate acts on the buffer body, thereby reducing the damage to the buffer body caused by the limit plate in the connecting groove.

[0016] Optionally, one end of the abutment column extending into the connecting block is provided with an elastic clamping piece, and the clamping piece is bent and passes through the side wall of the connecting block. The abutment column slides in the buffer body and the connecting block, and there is friction resistance between the abutment column and the connecting block. After the limiting plate is squeezed by the connecting groove wall, the limiting plate abuts the abutment column to drive the clamping piece to extend out of the connecting block and clamp against the installation groove wall.

[0017] By adopting the above technical solution, when the buffer body is deformed by impact, the buffer body squeezes the limit plate through the wall of the connecting groove, so that the end of the limit plate squeezes the abutting column. The abutting column drives the abutting piece to extend out of the connecting block and abut against the wall of the installation groove to increase the sliding resistance of the connecting block in the installation groove, and as the distance the buffer body slides due to collision increases, the longer the abutting piece extends, the greater the resistance of the connecting block in the installation groove. While limiting the connection block from rotating out of the installation groove, the reaction force of the buffer body after deformation is increased to buffer the hull. Therefore, by providing a abutting piece, the abutting piece is used to extend out of the connecting block due to the squeezing of the abutting column, the sliding resistance between the connecting block and the installation groove is increased, and the sliding distance of the buffer body on the fixed plate is reduced, thereby limiting the separation of the buffer body and the fixed plate.

[0018] Optionally, one end of the buffer body away from the fixing plate is bent in opposite directions and abuts against each other, and a buffer cavity 1 is formed between the buffer bodies.

[0019] By adopting the above technical solution, when the ship collides with the buffer body, the buffer body produces compression deformation, which makes the buffer cavity one shrink and the air pressure in the buffer cavity one increase, thereby increasing the restoring force of the buffer body and the reaction force of the buffer body on the hull, thereby improving the buffering effect of the buffer body.

[0020] Optionally, an air hole 1 connected to a buffer cavity 1 is formed at abutment portion of the buffer body away from the fixed plate.

[0021] By adopting the above technical scheme, when the buffer body is compressed and deformed after being hit, the air pressure in the buffer chamber increases, and the air in the buffer chamber is squeezed out from the air hole, so that the hull is affected by the restoring force of the buffer body while also being affected by the gas squeezed out from the air hole, thereby alleviating the expansion of the buffer body caused by the increase in air pressure in the buffer chamber, thereby making it easier to utilize the compressed air in the buffer chamber and cushion the hull.

[0022] Optionally, a second buffer cavity is provided in the buffer body, and a second air hole connected to the second buffer cavity is provided at the end of the buffer body away from the fixing plate.

[0023] By adopting the above technical solution, when the ship hull hits the buffer bodies at the same time or hits one of the buffer bodies alone, the buffer bodies are squeezed and deformed. While increasing the air pressure in the buffer chamber 1, the buffer body itself is also squeezed, so that the compressed air pressure in the buffer chamber 2 in the buffer body increases, and the gas in the buffer chamber 2 is squeezed out from the air hole 2, so that the gas squeezed out of the air hole 2 acts on the ship hull, further buffering the collision of the ship hull, thereby making it easier to utilize the space inside the buffer body.

[0024] On the other hand, the present application provides a method for installing a bridge pier anti-collision fender, comprising the following steps:

[0025] S1: When constructing a bridge pier, multiple fixing rods are pre-buried along the circumferential direction of the bridge pier, multiple holes are pre-drilled around the bridge pier for inserting the positioning rods, and the ends of the fixing rods protruding from the bridge pier are processed to form threads when the fixing rods leave the factory;

[0026] S2: Distribute the fixing plates around the circumference of the bridge pier, pass the end of the fixing rod exposed from the bridge pier through the fixing plate and the reinforcement plate, and tighten the nut on the fixing rod to tighten the reinforcement plate;

[0027] S3: Slide the connection block into the arc-shaped installation groove, and install and fix the buffer body at one end of the fixing plate on the fixing plate, and then use the deformation ability of the buffer body to stretch the other buffer body to slide the connection block into the installation groove, so as to splice the two buffer bodies to form a sphere and fix it on the fixing plate;

[0028] S4: bend the buffer bodies in directions away from each other to open the air holes, and then put the limit plate into the connection groove and rotate to connect with the abutment column;

[0029] S5: Insert the positioning rod from the air hole 1 and then pass through the limiting plate, and insert the end of the positioning rod into the reserved chisel hole until the locking plate abuts against the limiting plate, and the limiting plate is pressed tightly against the fixing plate.

[0030] By adopting the above technical solution, before installing the anti-collision fender, a plurality of fixing rods are embedded in advance when the bridge pier is constructed. The fixing rods are made of steel bars, and the exposed end of the fixing rods is processed to form threads when leaving the factory. Then, a plurality of chisel holes are drilled on the circumferential side wall of the bridge pier, so that the chisel holes are located between the fixing rods. Then, the fixing plates are distributed around the circumferential direction of the bridge pier, so that the ends of the fixing rods can pass through the fixing plates, so that the fixing plates are attached to the bridge pier. So that the end of the fixing rod with threads extends into the installation groove of the fixing plate, and then the reinforcement plate is placed in the installation groove, so that the end of the fixing rod can pass through the reinforcement plate. The nut is tightened on the end of the fixing rod, so that the nut presses the reinforcement plate against the installation groove, and then the fixing plate is pressed against the circumferential side wall of the bridge pier, reducing the direct damage caused by the nut to the fixing plate.

[0031] Then slide the connection block on the buffer body along one end of the installation slot, rotate the buffer body to drive the connection block to slide into the installation slot, so that the connection block covers the nut. After the buffer body on the upper end of the fixed plate is screwed in and installed, the buffer body is opened when installing the next buffer body, so that the connection block on the buffer body can slide into the installation slot below the fixed plate, and a pair of buffer bodies are installed on the fixed plate, so that the buffer bodies are spliced ​​to form a sphere fixed on the fixed plate.

[0032] Then, the buffer bodies are bent in the direction away from each other to open the air hole 1, and the limit plate is placed in the connection groove, so that the two ends of the limit plate are placed in the connection groove and sleeved on the abutment column. Then, the positioning rod is inserted from the air hole 1 and passed through the limit plate, and the end of the positioning rod is inserted into the chiseled hole reserved on the pier. Until the locking plate abuts against the limit plate, the limit plate is restricted from being separated from the plate, and then the buffer body is restricted from being separated from the fixed plate. Through the rotation connection of the limit plate, the positioning rod and the abutment column, the buffer bodies can be restored after being dislocated from each other, so that the buffer body is easy to reset after being hit.

[0033] The present invention has the following advantages:

[0034] 1. By placing the reinforcement plate in the installation groove and fixing the fixing plate to the circumferential side wall of the pier under the tightening of the nut, the fixing rod is connected to the pier and the reinforcement plate is tightened to the fixing plate to achieve double reinforcement, strengthen the connection stability between the fender and the pier, and thus increase the service life of the fender;

[0035] 2. By arranging the connection block to slide in the installation groove, the buffer body can slide relatively, so that the relatively sliding buffer body can further buffer the hull, thereby improving the buffering effect of the buffer body;

[0036] 3. By setting a limit plate, a positioning rod and a locking plate, the limit plate is pressed tightly by the locking plate and the positioning rod, and the inner side of the buffer body is pressed tightly against the fixing plate, and the interaction between the buffer bodies drives the dislocated buffer body to reset through the rotation of the limit plate on the positioning rod, so that the buffer body can automatically reset after being hit;

[0037] 4. By providing an abutment column and a tightening sheet, utilizing the rotational connection between the abutment column and the limiting plate, utilizing the tightening sheet to extend out of the connecting block as the abutment column is squeezed, the sliding resistance between the connecting block and the mounting groove is increased, and the sliding distance of the buffer body on the fixing plate is reduced, thereby limiting the separation of the buffer body and the fixing plate;

[0038] 5. By setting up buffer chamber 1, buffer chamber 2, air hole 1 and air hole 2, the air in buffer chamber 1 and buffer chamber 2 is compressed and the air pressure is increased, so that the compressed air can rush out from air hole 1 and air hole 2 to the hull to buffer the collision of the hull, thereby facilitating the use of the compressed air in the buffer body and buffering the hull.

DETAILED DESCRIPTION

[0043] The following will be combined with the attached Figure 1-Figure 3 The present invention is described in detail, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] The following is combined with Figure 1-3 The present application is further described in detail. The present invention provides a bridge pier anti-collision fender through improvement.

[0045] Reference Figure 1The anti-collision fender includes a plurality of fixed plates 1 fixed along the circumferential direction of the pier 3, and buffer bodies 2 installed at the upper and lower ends of the fixed plates 1. A pair of buffer bodies 2 are fixed on each fixed plate 1. The fixed plates 1 and the buffer bodies 2 are made of elastic rubber material. The buffer bodies 2 bulge and buffer the impact of the hull.

[0046] Reference Figure 2 The buffer bodies 2 are bent toward each other in the direction away from the fixing plate 1, so that the buffer bodies 2 abut against each other to form a sphere. A buffer cavity 21 is formed between the buffer bodies 2, and an air hole 211 connected to the buffer cavity 21 is formed at the abutment of the end of the buffer body 2 away from the fixing plate 1, so that after the hull squeezes and collides with the buffer body 2, the buffer cavity 21 is compressed and the air is squeezed out from the air hole 211 and blown toward the hull to buffer the hull.

[0047] Reference Figure 2 A buffer cavity 22 is provided inside the buffer body 2, and an air hole 221 connected to the buffer cavity 22 is provided at one end of the buffer body 2 away from the fixing plate 1, so that after the hull hits the buffer body 2, the buffer cavity 22 in the buffer body 2 is compressed to squeeze the air out of the air hole 221, so that the air squeezed out of the air hole 221 acts on the hull to further buffer the impact of the hull.

[0048] Reference Figure 1 and Figure 2 The fixing plate 1 is provided with a mounting groove 12, which is arc-shaped and passes through the side walls on both sides of the fixing plate 1. The fixing plate 1 is penetrated by a plurality of fixing rods 11, which are made of steel bars. One end of the fixing rod 11 is pre-buried in the pier 3, and the other end after passing through the fixing plate 1 is located in the mounting groove 12. A reinforcing plate 13 is placed in the mounting groove 12 and is attached to the groove wall of the mounting groove 12. The end of the fixing rod 11 also passes through the reinforcing plate 13, so that the end of the fixing rod 11 passing through the fixing plate 1 and the reinforcing plate 13 is threadedly connected with a nut 111. The nut 111 presses the reinforcing plate 13 against the fixing plate 1 to prevent the fixing plate 1 from being separated from the pier 3, thereby preventing the buffer body 2 from being separated from the fixing plate 1.

[0049] Reference Figure 2 The end of the buffer body 2 close to the fixing plate 1 is integrally formed with a connecting block 23, and the cross-sectional shape of the connecting block 23 gradually expands in a direction away from the buffer body 2, forming a dovetail shape. The connecting block 23 covers the nut 111, and the connecting block 23 slides in the mounting groove 12, so that the buffer body 2 can rotate on the fixing plate 1, so that after the buffer body 2 rotates on the fixing plate 1, the connecting block 23 is rotated into the mounting groove 12.

[0050] Reference Figure 2A limiting plate 24 is placed between the buffer bodies 2 on the fixed plate 1, and the two ends of the limiting plate 24 correspond to the two buffer bodies 2 on the fixed plate 1 respectively. The buffer body 2 is provided with connecting grooves 25 for the two ends of the limiting plate 24 to be inserted into. When installing, it is only necessary to break the buffer body 2 apart and insert the two ends of the limiting plate 24 into the connecting grooves 25. The limiting plate 24 can make the upper and lower buffer bodies 2 of the fixed plate 1 slide synchronously after being hit.

[0051] Reference Figure 1 and Figure 2 A positioning rod 26 is passed through the center of the limiting plate 24. The positioning rod 26 is a steel bar that passes through the pier 3. A hole is drilled in the pier 3 for the positioning rod 26 to be inserted. A locking plate 27 is fixedly connected to the end of the positioning rod 26. The locking plate 27 abuts against the side of the limiting plate 24 that is away from the fixed plate 1. The positioning rod 26 is the axis of rotation of the limiting plate 24 on the fixed plate 1. The locking plate 27 restricts the limiting plate 24 from being separated from the fixed plate 1 and the connecting groove 25.

[0052] Reference Figure 2 An abutment column 231 extending into the connection block 23 is slidably disposed in the connection groove 25, and the abutment column 231 slides in a direction perpendicular to the length of the limiting plate 24. The abutment column 231 has sliding friction resistance in the connection block 23, and the end of the abutment column 231 located in the connection groove 25 rotates in the limiting plate 24, so that the limiting plate 24 rotates with the buffer body 2, reducing the damage to the buffer body 2 caused by the limiting plate 24 rotating in the connection groove 25.

[0053] Reference Figure 2 The end of the abutting column 231 located in the connecting block 23 is fixedly connected with a tightening piece 232, which is made of elastic rubber material. The tightening piece 232 bends and extends in the direction of the positioning rod 26 and can be out of the connecting block 23. After the buffer body 2 is hit, the wall of the connecting groove 25 squeezes the end of the limiting plate 24, and the limiting plate 24 pushes the abutting column 231 to slide, so that the tightening piece 232 slides out of the connecting block 23. When not hit, the tightening piece 232 is completely located in the connecting block 23. The end of the tightening piece 232 away from the abutting column 231 extends between the connecting block 23 and the mounting groove 12, increasing the resistance of the connecting block 23 sliding in the mounting groove 12, and reducing the sliding distance of the buffer body 2 after being hit.

[0054] The implementation principle of a bridge pier anti-collision fender in an embodiment of the present application is as follows: when the anti-collision fender is installed on the bridge pier 3, a plurality of fixing rods 11 are pre-embedded on the bridge pier 3, and then the fixing plate 1 is attached to the side wall of the bridge pier 3, so that the fixing plate 1 surrounds the circumferential side wall of the bridge pier 3. The fixing rod 11 is inserted into the installation groove 12 of the fixing plate 1, and the reinforcing plate 13 is placed in the installation groove 12 for the fixing rod 11 to pass through, and then the nut 111 is screwed on, so that the nut 111 is pressed against the reinforcing plate 13 to fix the fixing plate 1 to the circumferential side wall of the bridge pier 3. Then a connecting block 23 of a buffer body 2 is screwed in from one end of the installation groove 12 to connect one of the buffer bodies 2 to the fixing plate 1. Then the other buffer body 2 is moved to slide the connecting block 23 into the installation groove 12, so that the buffer body 2 and the fixing plate 1 are connected. Then, the two ends of the limit plate 24 are inserted into the connecting groove 25, and the positioning rod 26 is inserted into the pier 3 after passing through the limit plate 24, so as to further limit the limit plate 24 and the buffer body 2, so that the buffer body 2 is doubly fixed, thereby strengthening the connection stability between the fender and the pier 3, thereby increasing the service life of the fender.

[0055] The embodiment of the present application also discloses a method for installing a bridge pier anti-collision fender, which improves the connection between the anti-collision fender and the bridge pier 3, and installs the anti-collision fender on the circumferential side wall of the bridge pier 3, so as to cushion the hull when the hull hits the bridge pier 3, and also protect the bridge pier 3, reducing the damage to the bridge pier 3. Figure 2 and Figure 3 , including the following steps:

[0056] The fixing rods 11 are embedded in the circumferential side wall below the pier 3 when the pier 3 is constructed. The ends of the embedded fixing rods 11 are processed to have threads after leaving the factory. A plurality of holes are drilled between the fixing rods 11 on the circumferential side wall of the pier 3 so that the positioning rods 26 can be inserted.

[0057] The fixing plate 1 is fixed, and the reinforcing plate 13 is first placed in the installation groove 12, and the reinforcing plate 13 is moved toward the pier 3 together with the fixing plate 1, so that the threaded end of the fixing rod 11 passes through the fixing plate 1 and the reinforcing plate 13, so that the fixing plate 1 is tightly attached to the circumferential side wall of the pier 3. At this time, the end of the fixing rod 11 extends into the installation groove 12, and then the nut 111 is tightened on the threaded end of the fixing rod 11, so that the nut 111 is pressed against the reinforcing plate 13, and then the fixing plate 1 is pressed against the circumferential side wall of the pier 3, so that the circumferential side wall of the pier 3 is evenly surrounded by a plurality of fixing plates 1, and there are two fixing plates 1 in the vertical direction.

[0058] The buffer body 2 is fixed, first the buffer body 2 at the upper end of the fixing plate 1 is fixed, and the connecting block 23 of the buffer body 2 is aligned with the mounting groove 12 and slid into the mounting groove 12, and the buffer body 2 is rotated to slide into the mounting groove 12. When the buffer body 2 at the lower end of the fixing plate 1 is fixed, the buffer body 2 needs to be moved so that the connecting block 23 of the lower end buffer body 2 can slide into the mounting groove 12, and the connecting block 23 is also slid into the mounting groove 12 by rotating the buffer body 2. The two buffer bodies 2 are spliced ​​to each other to form a sphere, and the air hole 1 211 is aligned.

[0059] The buffer bodies 2 are connected to each other, and the spliced ​​buffer bodies 2 are broken apart to expand the air hole 1 211. Then the limit plate 24 is placed in the buffer cavity 1 21, and the two ends of the limit plate 24 are inserted into the connecting groove 25 to connect the buffer bodies 2 at the upper and lower ends of the fixing plate 1 through the limit plate 24. When the buffer body 2 at the lower end of the fixing plate 1 is hit, it can drive the buffer body 2 at the upper end of the fixing plate 1 to slide, and the sliding distance of the buffer body 2 at the lower end of the fixing plate 1 is reduced by sliding the connecting block 23 in the installation groove 12, thereby increasing the buffering force of the buffer body 2 on the hull.

[0060] Double fixation, finally, pass the positioning rod 26 through the middle part of the limit plate 24, so that the positioning rod 26 is inserted into the pre-flowed hole on the pier 3, and the locking plate 27 is abutted against the limit plate 24, so that the limit plate 24 rotates along the fixed plate 1 to limit the limit plate 24 from detaching from the fixed plate 1, and then limit the buffer body 2 from detaching from the fixed plate 1, thereby realizing double fixation of the buffer body 2 and the fixed plate 1.

[0061] The implementation principle of the installation method of the anti-collision fender of the pier 3 in the embodiment of the present application is as follows: the reinforcing plate 13 is tightened by the nut 111, and the fixing plate 1 is pressed and fixed to the circumferential side wall of the pier 3, and after the positioning rod 26 is inserted into the drilled hole, the limiting plate 24 is restricted from being separated from the fixing plate 1 and the buffer body 2 is restricted from being separated from the fixing plate 1 by the locking plate 27, so that after the buffer body 2 is connected to the fixing plate 1 through the connecting block 23, it can also be restricted from being separated from the fixing plate 1 by the positioning rod 26 and the locking plate 27, thereby realizing double fixation of the buffer body 2 and the fixing plate 1.
