DETAILED DESCRIPTION
[0029] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.
[0030] Embodiment 1:
[0031] like Figure 1-7 As shown, the partially detachable and replaceable bridge anti-collision device provided by the utility model comprises: a front guard plate 1, a fixed plate 2, a plurality of clamps 3 are installed on the back of the fixed plate 2, the clamps 3 are clamped and fixed on the upright posts of the bridge guardrail, a first buffer mechanism, a second buffer mechanism and a third buffer mechanism are arranged between the front guard plate 1 and the fixed plate 2; the first buffer mechanism comprises four guide columns 4, a first spring 5 is sleeved on the guide column 4, one end of the guide column 4 is fixed to the front guard plate 1, and the other end passes through the fixed plate 2 and is installed with a nut; the second buffer mechanism comprises two first installation grooves 6 opened on the front side of the fixed plate 2, the first installation grooves 6 are provided on the front side of the fixed plate 2, and the second installation grooves 6 are provided on the front side of the fixed plate 2. A removable first screw rod 7 is installed in the groove 6, and both ends of the first screw rod 7 extend out of both sides of the fixing plate 2 and are installed with nuts. A slider 9 is slidably installed on the first screw rod 7, and a second spring 11 is installed between the slider 9 and the inner wall of the first installation groove 6. The second spring 11 is sleeved on the first screw rod 7. A connecting rod 10 is rotatably installed on one side of the slider 9, and pressure plates 8 are installed at the ends of the two connecting rods 10. The pressure plate 8 and the connecting rod 10 are rotatably connected; the third buffer mechanism includes a buffer bag 12 installed on the back side of the front guard plate 1, the buffer bag 12 is filled with gas, and is adhered to the back side of the front guard plate 1 with double-sided tape or Velcro. When in use, when a vehicle hits a bridge guardrail, the vehicle first hits the front guard plate 1, causing the front guard plate 1 to approach the fixed plate 2, causing the guide column 4 to move toward the fixed plate 2 and compress the first spring 5 to perform the first energy absorption. If the impact force is large, the front guard plate 1 continues to move toward the fixed plate 2, causing the front guard plate 1 to squeeze the pressure plate 8, squeezing the pressure plate 8 toward the fixed plate 2 to move it, and the pressure plate 8 moves, and the connecting rod 10 causes the slider 9 to move to both sides in the first mounting groove 6, thereby squeezing the second spring 11, and performing the second energy absorption through the second spring 11. If the vehicle has not stopped , it will squeeze the front guard plate 1 to continue to move toward the fixed plate 2, so that the buffer capsule 12 contacts the fixed plate 2. Due to the squeezing effect, the buffer capsule 12 is deformed by force, and the third energy absorption is performed. Through the triple energy absorption, the damage caused by the rigid impact to the guardrail and the vehicle is reduced. When the first buffer mechanism, the second buffer mechanism or the third buffer mechanism is damaged, the first buffer mechanism and the second buffer mechanism can be conveniently disassembled by removing the nut on the guide column 4 and the first screw 7. The buffer capsule, which is the main component of the third buffer mechanism, can be directly torn off and replaced when damaged. In this way, the damaged parts can be replaced separately without having to replace the entire part, which can effectively reduce the loss.
[0032] By providing a front guard plate 1 and a fixed plate 2, and providing a first buffer mechanism, a second buffer mechanism and a third buffer mechanism that can be easily disassembled between the front guard plate 1 and the fixed plate 2, multiple energy absorption can be performed when a vehicle hits a guardrail, thereby reducing the impact force on the vehicle and the guardrail, and the damaged part can be partially replaced, thereby effectively reducing the loss.
[0033] Embodiment 2:
[0034] like Figure 6 As shown, the front guard plate 1 includes a support plate 13, and the guide column 4 and the buffer bag 12 are all connected to the support plate 13. A porous energy absorbing plate 14 is installed on the front of the support plate 13, and a first bolt 15 is installed between the energy absorbing plate 14 and the support plate 13. When in use, when a vehicle collides, the vehicle first contacts the energy absorbing plate 14. At the first moment of the collision, the porous energy absorbing plate 14 breaks and shatters, and then absorbs energy to reduce the damage to the vehicle. When replacing the energy absorbing plate 14 later, it is only necessary to remove the first bolt 15 to conveniently replace the energy absorbing plate 14 separately.
[0035] By providing the front guard plate 1 including the support plate 13, the energy absorbing plate 14 and the first bolt 15, when a collision occurs, the energy absorbing plate 14 can be crushed to absorb energy, thereby reducing the damage to the vehicle caused by the collision, and can be replaced separately.
[0036] Embodiment 3:
[0037] like Figure 3-4 As shown, two second mounting grooves 16 are provided on the back of the fixing plate 2, and one end of the clamp 3 is slidably installed in the second mounting groove 16, so that the installation position of the clamp 3 can be conveniently adjusted according to the position and spacing of the guardrail column. It is worth noting that the two sides of the second mounting groove 16 do not exceed the guide column 4, that is, the column clamped by the clamp 3 is misaligned with the guide column 4, and the guide column 4 will not resist the guardrail column (including the beam) when moving.
[0038] By providing the second installation groove 16 on the back side of the fixing plate 2, the installation position of the clamp 3 can be easily adjusted so as to be suitable for use with columns of different spacings.
[0039] Embodiment 4:
[0040] like Figure 3 and Figure 7 As shown, a second screw 17 is installed in the second mounting groove 16, and both ends of the second screw 17 extend out of the fixing plate 2 and are installed with nuts. The second screw 17 passes through the clamp 3, and the clamp 3 can move along the axial direction of the second screw 17 in the second mounting groove 16, thereby limiting and guiding the clamp 3. The nut can be unscrewed and the second screw 17 can be pulled out, so that the clamp 3 can be removed and replaced conveniently.
[0041] By installing the second screw rod 17 in the second installation groove 16 , the clamp 3 can be limited and guided, and the clamp 3 can be easily replaced separately.
[0042] Embodiment 5:
[0043] like Figure 7As shown, the clamp 3 includes two clamping blocks 18 with holes, the two clamping blocks 18 are provided with V-shaped clamping grooves and installed with second bolts 19, the second screw 17 passes through the clamping blocks 18, the clamping grooves are aligned with the column sleeve, and then the second bolts 19 are tightened, so that the clamp 3 can be clamped and fixed on the column, and then the device can be fixed to the front end of the guardrail.
[0044] By providing a clamp 3 including two clamping blocks 18 and a second bolt 19, the device can be conveniently fixed to the front end of the guardrail.
[0045] Embodiment 6:
[0046] The cushion bag 12 is filled with high-pressure inert gas. In the event of a severe collision, the cushion bag 12 is damaged and the high-pressure inert gas in the cushion bag 12 is released in a short time, thereby reducing the oxygen content in the impact area of the front end of the vehicle and reducing the possibility of fire or even explosion caused by the collision.
[0047] By filling the cushion bag 12 with high-pressure inert gas, the possibility of fire or even explosion caused by vehicle collision can be reduced, thereby increasing the probability of survival of personnel.
[0048] Working principle: When in use, when a vehicle hits a bridge guardrail, the vehicle first hits the front guard plate 1, causing the front guard plate 1 to approach the fixed plate 2, causing the guide column 4 to move toward the fixed plate 2 and compress the first spring 5 to perform the first energy absorption. If the impact force is large, the front guard plate 1 continues to move toward the fixed plate 2, causing the front guard plate 1 to squeeze the pressure plate 8, squeezing the pressure plate 8 toward the fixed plate 2 to move it, and the pressure plate 8 moves, and the connecting rod 10 causes the slider 9 to move to both sides in the first mounting groove 6, thereby squeezing the second spring 11, and performing the second energy absorption through the second spring 11. If the vehicle has not If the front guard plate 1 stops, it will squeeze the front guard plate 1 to continue to move toward the fixed plate 2, so that the buffer capsule 12 contacts the fixed plate 2. Due to the squeezing effect, the buffer capsule 12 is deformed by force, and the third energy absorption is performed. Through the triple energy absorption, the damage caused by the rigid impact to the guardrail and the vehicle is reduced. When the first buffer mechanism, the second buffer mechanism or the third buffer mechanism is damaged, the first buffer mechanism and the second buffer mechanism can be conveniently disassembled by removing the nut on the guide column 4 and the first screw 7. The buffer capsule, which is the main component of the third buffer mechanism, can be directly torn off and replaced when it is damaged. In addition, the damaged parts can be replaced separately without replacing the entire part, which can effectively reduce the loss. It is worth mentioning that the high-pressure inert gas in the buffer capsule 12 will be released in a short time when the buffer capsule 12 is damaged, so that the oxygen content in the impact part of the front end of the vehicle is reduced, reducing the possibility of fire or even explosion caused by the impact.
