[0017] The present application is further described in detail below in conjunction with the accompanying drawings.
[0018] The embodiment of the present application discloses an anti-collision protection device for road and bridge construction.
[0019] Reference Figure 1 , Figure 2 The anti-collision protection equipment for road and bridge construction includes a plurality of anti-collision protection seats 1 for being arranged around the pier base. The anti-collision protection seats 1 are fixedly installed outside the pier base through anchor rods, and adjacent anti-collision protection seats 1 are arranged in sequence and at intervals. A buoy 2 floating on the water surface is movably arranged between two adjacent anti-collision protection seats 1.
[0020] like Figure 1 , Figure 2 As shown, the anti-collision protection seat 1 is provided with a slide bar 10 facing each buoy 2, the length of the slide bar 10 is set along the lifting direction of the buoy 2, and the slide bar 10 is respectively located on both sides of the buoy 2. The buoy 2 is movably arranged between the slide bars 10 on both sides along the length direction of the slide bar 10. When the water level continues to rise, the buoy 2 will rise synchronously along the length direction of the slide bar 10 under the action of buoyancy. Similarly, when the water level gradually drops, the buoy 2 will drop synchronously along the length direction of the slide bar 10 under the action of its own gravity.
[0021] like Figure 1 , Figure 2 As shown, a vertically arranged linkage rod 3 is fixedly installed on the top of the buoy 2, and a same lifting frame 4 is fixedly installed on the top of each linkage rod 3. The lifting frame 4 is arranged horizontally and is sleeved on the outside of the bridge pier. A waterproof floating curtain 5 is arranged on the lifting frame 4 and surrounds the bridge pier in a circumferential direction. The waterproof floating curtain 5 is made of waterproof cloth. The bottom of the waterproof floating curtain 5 is fixedly arranged on the bridge pier base, and the connection between the bottom of the waterproof floating curtain 5 and the bridge pier base is waterproof and sealed. The top of the waterproof floating curtain 5 is fixedly arranged on the lifting frame 4, and the top of the waterproof floating curtain 5 will rise and fall synchronously with the lifting frame 4.
[0022] When the water level around the pier base gradually rises, the buoy 2 will drive the lifting frame 4 to rise synchronously. As the height of the lifting frame 4 continues to rise, the lifting frame 4 will synchronously drive the waterproof floating curtain 5 to gradually unfold upward, and the waterproof floating curtain 5 will be used to block the area around the pier base, thereby building a temporary protection area for construction personnel, effectively preventing the rising water level from flooding the construction area of the pier base, and also providing a water level rising warning for the construction personnel on the pier base, creating favorable conditions for the evacuation and escape of the construction personnel, ensuring the construction safety of the construction personnel, and effectively reducing the financial losses caused by the flooding of construction equipment.
[0023] like Figure 1 , Figure 2 As shown, a plurality of support rods 50 are fixedly installed on the pier base and arranged in a circumferentially spaced ring arrangement on the outside of the waterproof floating curtain 5. The length of the support rods 50 is set along the lifting direction of the lifting frame 4. A plurality of groups of through rings 51 corresponding to the support rods 50 are fixedly arranged on the outer wall of the waterproof floating curtain 5. The through rings 51 in the same group are movably arranged on the outside of the respective supporting rods 50 in sequence along the length direction of the supporting rods 50. When the lifting frame 4 drives the top of the waterproof floating curtain 5 to gradually rise, the cooperation between the through rings 51 and the supporting rods 50 can ensure that the waterproof floating curtain 5 is unfolded along a specified path, and at the same time, the stability of the waterproof floating curtain 5 when unfolded can be ensured.
[0024] like Figure 1 , Figure 2 As shown, a raised platform 6 surrounding the pier in a circumferential direction is fixedly installed on the top of the support rod 50. The raised platform 6 is fixedly installed outside the pier, and the raised platform 6 can be used for construction workers to stand. The support rod 50 is used to support and fix the raised platform 6. A climbing ladder 60 located inside the waterproof floating curtain 5 is fixedly installed between the raised platform 6 and the pier base. The climbing ladder 60 is used for construction workers on the pier base to enter and exit the raised platform 6. When the water level rises quickly, making it impossible for construction workers to escape in time, the construction workers can use the climbing ladder 60 to enter the raised platform 6 above, thereby creating favorable conditions for rescue work, gaining more rescue time, and further ensuring the personal safety of construction workers.
[0025] like Figure 3 , Figure 4 As shown, in order to ensure the stability and reliability of the waterproof floating curtain 5 in the unfolded state, a self-locking mechanism 7 is also provided on the pier base, and the self-locking mechanism 7 includes a sliding frame 70 movably provided on the top of the anti-collision protection seat 1, and the top of the anti-collision protection seat 1 is fixedly provided with guide rods 72 symmetrically provided on the left and right sides of the sliding frame 70, and the guide rods 72 on both sides are horizontally provided, and the length of the guide rods 72 extends along the front and rear direction of the sliding frame 70. The sliding frame 70 is movably provided between the guide rods 72 on both sides along the length direction of the guide rods 72, and a locking rod 71 facing the adjacent linkage rod 3 is fixedly installed on the sliding frame 70.
[0026] like Figure 3 , Figure 4 As shown, the linkage rod 3 is provided with locking holes 30 for the respective relative locking rods 71 to pass through. When the linkage rod 3 rises to the highest point following the buoy 2, the locking holes 30 will be opposite to the locking rods 71, and the locking holes 30 are located on the sliding paths of the respective relative locking rods 71.
[0027] like Figure 3 , Figure 4As shown, the outer sleeve of the guide rod 72 is provided with a return spring 73, and the return spring 73 is extended and retracted along the sliding direction of the sliding frame 70. The return spring 73 is used to push the locking rod 71 to withdraw from the respective relative locking holes 30. The self-locking mechanism 7 also includes a plurality of self-controlled floating cylinders 74 floating on the water surface. The pier base is provided with positioning rods 8 respectively located between two adjacent anti-collision protection seats 1, and the positioning rods 8 are vertically arranged. The self-controlled floating cylinders 74 are respectively movably arranged on the outside of the respective relative positioning rods 8, and the self-controlled floating cylinders 74 are lifted and lowered along the length direction of the positioning rods 8. A limit plate 80 is fixedly provided on the top of the positioning rod 8, and the limit plate 80 is used to limit the self-controlled floating cylinder 74 from detaching from the top of the positioning rod 8, and also limits the maximum floating height of the self-controlled floating cylinder 74.
[0028] like Figure 4 , Figure 5 as well as Figure 6 As shown, a water injection hole 740 is provided at the top of the self-controlled float cylinder 74, a drainage hole 741 is provided at the bottom of the self-controlled float cylinder 74, and a single-off valve assembly 9 for covering and sealing the drainage hole 741 is provided at the bottom of the self-controlled float cylinder 74. The single-off valve assembly 9 is used to prevent the water injected into the self-controlled float cylinder 74 from being discharged from the bottom drainage hole 741.
[0029] like Figure 4 , Figure 5 as well as Figure 6 As shown, a suspension rope 75 is fixedly arranged between the self-controlled floating cylinder 74 and the adjacent sliding frame 70. When the water level around the pier base is low, the waterproof floating curtain 5 will be in a retracted state, and the self-controlled floating cylinder 74 will remain in an elevated state under the traction of the return spring 73 and the suspension rope 75. At this time, the locking rod 71 will remain separated from the respective relative locking holes 30.
[0030] As the water level continues to rise, the buoy 2 will drive the linkage rod 3 and the lifting frame 4 to gradually rise. When the water level line overflows the water injection hole 740 on the top of the automatic floating cylinder 74, water will flow back into the automatic floating cylinder 74. In order to ensure that the automatic floating cylinder 74 can sink smoothly, a counterweight block of appropriate weight can also be installed in the automatic floating cylinder 74. As the overall weight of the automatic floating cylinder 74 continues to increase, the overall weight of the automatic floating cylinder 74 will gradually exceed the resilience of the return spring 73. At this time, the automatic floating cylinder 74 will continue to sink along the positioning rod 8. At the same time, the automatic floating cylinder 74 will pull the sliding frame 70 through the suspension rope 75 to move in the direction close to the linkage rod 3. When the locking hole 30 on the linkage rod 3 rises to be opposite to the locking rod 71, the buoy 2 floats to the highest position, and the locking rod 71 will be automatically inserted into the locking hole 30 under the traction of the self-controlled float cylinder 74. It should be mentioned that the length of the locking hole 30 is slightly larger than the diameter of the locking rod 71. When the locking rod 71 is inserted into the locking hole 30, the linkage rod 3 still has a certain up and down movable distance, thereby preventing the locking rod 71 from getting stuck.
[0031] By interfitting the locking rod 71 with the locking hole 30 , the waterproof floating curtain 5 in the unfolded state can be locked, which effectively alleviates the situation where the waterproof floating curtain 5 shakes violently due to the fluctuation of the water surface and ensures the stability and reliability of the waterproof floating curtain 5 .
[0032] like Figure 4 , Figure 5 as well as Figure 6 As shown, a top rod 76 located below the self-control float cylinder 74 is fixedly installed on the pier base, and the top rod 76 is opposite to the drainage hole 741, and the diameter of the drainage hole 741 is larger than the diameter of the top rod 76. When the self-control float cylinder 74 sinks to a specified height, the top rod 76 is used to be inserted into the drainage hole 741 and open the single-off valve assembly 9.
[0033] like Figure 5 , Figure 6 As shown, the single-off valve assembly 9 includes a limit rod 90 fixedly arranged on the inner wall of the self-controlled floating cylinder 74, and the limit rod 90 is symmetrically arranged on both sides of the drainage hole 741, and the limit rod 90 is arranged vertically. A sealing plate 91 for sealing and covering the drainage hole 741 is movably penetrated on the limit rod 90, and the sealing plate 91 is lifted and lowered in the self-controlled floating cylinder 74 along the length direction of the limit rod 90. A reset spring 92 is sleeved on the outside of each limit rod 90, and the reset spring 92 is extended and retracted along the lifting direction of the sealing plate 91, and the reset spring 92 is used to push the sealing plate 91 to compress and seal the drainage hole 741.
[0034] like Figure 4 , Figure 5 as well as Figure 6 As shown, the positioning rod 8 is also provided with a positioning spring 81 located below the self-control float cylinder 74, and the positioning spring 81 is used to push the self-control float cylinder 74 to reset upward along the positioning rod 8. When the self-control float cylinder 74 sinks to a specified height, the top rod 76 will be inserted into the drainage hole 741, and the sealing plate 91 will remain in an open state under the push of the top rod 76. Since the self-control float cylinder 74 is full of water at this time, the self-control float cylinder 74 will still remain in a sinking state, and finally the self-control float cylinder 74 will push the positioning spring 81 to remain in a compressed state.
[0035] When the water level around the pier base drops to a specified height, the water in the self-control float cylinder 74 will gradually be discharged from the drainage hole 741 in the open state, and as the water in the self-control float cylinder 74 is continuously discharged, the overall weight of the self-control float cylinder 74 will gradually decrease, and finally the self-control float cylinder 74 will gradually float up and reset along the positioning rod 8 under the elastic force of the positioning spring 81 and the return spring 73, until the locking rod 71 is withdrawn from the locking hole 30, and the float cylinder 2 can float freely. The automatic locking and unlocking of the height of the waterproof floating curtain 5 is realized by the rise and fall of the water level, which is a clever design, greatly saving manpower and material resources, and achieving the effect of energy saving and environmental protection.
[0036] The implementation principle is: when the water level around the pier base gradually rises, the buoy 2 will drive the lifting frame 4 to rise synchronously. As the height of the lifting frame 4 continues to rise, the lifting frame 4 will synchronously drive the waterproof floating curtain 5 to gradually unfold upward, and the waterproof floating curtain 5 is used to block the area around the pier base, thereby building a temporary protection area for construction personnel, effectively preventing the rising water level from flooding the construction area of the pier base, and at the same time providing a water level rising warning for the construction personnel on the pier base, creating favorable conditions for the evacuation and escape of the construction personnel, ensuring the construction safety of the construction personnel, and effectively reducing the financial losses caused by the flooding of construction equipment.
[0037] By interfitting the locking rod 71 with the locking hole 30 , the waterproof floating curtain 5 in the unfolded state can be locked, which effectively alleviates the situation where the waterproof floating curtain 5 shakes violently due to the fluctuation of the water surface and ensures the stability and reliability of the waterproof floating curtain 5 .
[0038] When the water level around the pier base drops to a specified height, the water in the self-controlled float cylinder 74 will gradually be discharged from the drainage hole 741 in the open state, and as the water in the self-controlled float cylinder 74 is continuously discharged, the overall weight of the self-controlled float cylinder 74 will gradually decrease. Finally, the self-controlled float cylinder 74 will gradually float up and reset along the positioning rod 8 under the elastic force of the positioning spring 81 and the return spring 73, until the locking rod 71 is withdrawn from the locking hole 30, at which time the buoy 2 can float freely.
[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
