Description

Technical Field

[0001] The invention relates to the technical field of bridge anti-collision, and in particular to a novel self-resetting bridge pier anti-collision device. Background Art

[0002] With the economic construction and development of my country, the transportation infrastructure is also developing rapidly. Bridges are constantly rising from the ground. Bridges bear the heavy responsibility of economic development in both places and are also related to people's livelihood issues. More and more large-scale bridge projects are being established, including bridge projects worth hundreds of millions and tens of billions of yuan.

[0003] While land transportation is developing, the development of water transportation should not be underestimated. The size and tonnage of ships are getting bigger and bigger, and the waterways are becoming crowded. Water transportation is also developing continuously. The advantages and disadvantages of water transportation are being discussed continuously. The subject of water transportation also requires our serious research. In recent years, accidents of ships hitting bridge piers are common, which are caused by natural factors and man-made accidents; however, such accidents often cause huge economic losses. Ships will suffer huge damage during the collision, and bridges will also suffer huge damage during the collision. Piers will crack due to the huge impact force, causing unsafe factors. If the tonnage of the ship is too large, hitting the bridge will cause the bridge to collapse directly and then cause the ship to sink. This constitutes a huge economic loss. It is well known that the value of the bridge is not only reflected in its high cost, but also in the social value it bears. Therefore, the research and development of bridge pier anti-collision is particularly important. It is uneconomical and unrealistic to simply increase the anti-collision load of the bridge pier design from the surface, so it is particularly important to develop an economical and realistic bridge pier anti-collision device. At present, most bridge piers on rivers use simple springs and rubber laying to buffer the impact of ships, and some use floating boats and other technologies to protect bridge piers. They each have their own advantages and disadvantages. The simple installation of springs and laying rubber has the advantage of simple and convenient installation, but they have only a small buffering capacity, and the impact of ships will still be transmitted and act on the bridge piers. The floating boat technology has the problem of being easily damaged and complicated to replace. Therefore, a bridge pier anti-collision device is needed, which can effectively absorb the impact energy of ships to achieve a buffering effect, and can also allow the ship to turn around so that most of the energy remains on the ship, which can reduce the damage to the bridge and the ship during the collision, and also has the advantage of simple installation.

[0004] Based on the above reasons, the present invention designs a novel self-resetting bridge pier anti-collision device. Summary of the invention

[0005] The object of the present invention is to overcome the deficiencies of the prior art and provide a new type of self - resetting pier anti - collision device, which can effectively prevent the direct collision between ships and piers, convert the collision between the pier and the ship into the collision between the ship and the anti - collision device, and the anti - collision device buffers the huge impact force generated when the ship hits the pier through its own buffer energy - consuming device, protecting both the bridge structure from damage and the ship.

[0006] In order to achieve the object of the present invention, the technical solution adopted by the present invention is as follows:

[0007] The present invention discloses a new type of self - resetting pier anti - collision device, including a pier, an external bearing platform, a main steel frame, an anti - collision steel block, a trapezoidal rubber block and a blocking iron plate. The external bearing platform is arranged in a circular structure outside the pier. The main steel frame is in a "C" - shaped structure, and its bottom is fixed to the top of the external bearing platform through fixing bolts. The anti - collision steel block and the blocking iron plate are in a square structure, and their tops and bottoms are respectively slidably matched with the top and bottom inner walls of the main steel frame. Limiting blocks integrally formed with the main steel frame are provided at the inner ends of the top and bottom of the inner wall of the main steel frame, and built - in springs are respectively connected between the outer end faces of the limiting blocks and the top and bottom inner walls of the blocking iron plate. The outer wall of the anti - collision steel block is connected to the trapezoidal rubber block, and energy - absorbing buffer material layers are provided on the inner wall of the anti - collision steel block and the outer wall of the blocking iron plate.

[0008] The energy - absorbing buffer material layer is semi - cylindrical energy - absorbing buffer blocks arranged in a rectangular array on the inner wall of the anti - collision steel block and the outer wall of the blocking iron plate.

[0009] One end of a steel wire rope is fixedly connected to the outer end of the bottom of the limiting block at the inner end of the top of the inner wall of the main steel frame. An inverted "L" - shaped bracket is fixed on the outer wall of the external bearing platform, and a heavy object block is placed on the bracket. The steel wire rope is fixedly connected to the top of the heavy object block through a reserved pipeline arranged in the main steel frame. A push plate is provided in the middle of the inner wall of the blocking iron plate, and a semi - circular hole for the steel wire rope to pass through is provided in the middle of the inner end of the push plate.

[0010] The external bearing platform is in a right - angled trapezoidal structure with a narrow top and a wide bottom, and the bracket is fixed on its outer inclined surface.

[0011] The trapezoidal rubber block is in a right - angled trapezoidal structure with a wide top and a narrow bottom, and it is made of butyl rubber material.

[0012] Pulleys are installed on the top and bottom of the anti - collision steel block, and the pulleys roll in cooperation with the inner wall of the main steel frame.

[0013] A fixed pulley is provided at the corner of the reserved pipeline for the steel wire rope to pass through in the main steel frame.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. When the ship collides with the device, the present invention causes the anti-collision steel block with a pulley to slide inward, compressing the energy-absorbing buffer material layer and consuming part of the impact energy. Meanwhile, the impact energy continues to be transmitted to the blocking steel plate, which continues to move inward to thereby have a built-in spring, thereby converting part of the impact energy into elastic potential energy. When the blocking steel plate moves inward, it forces the steel rope to move inward to pull the heavy block connected to the lower part of the steel rope, thereby converting a large amount of impact energy into gravitational potential energy, thereby effectively preventing damage to the bridge caused by the direct impact of the ship and protecting the bridge.

[0016] 2. The present invention can effectively resolve the impact of ships through energy-absorbing buffer materials, built-in springs, and steel ropes connected to heavy objects, reduce damage to the device, and extend the life of the device. It also has the ability to recover after a collision. When a non-centering collision occurs between the ship and the device, the ship's heading is changed while the self-resetting device allows the ship to retain a certain amount of energy.

[0017] 3. The present invention installs a trapezoidal rubber block on the outside of the anti-collision steel block. The trapezoidal rubber block is designed to be wide at the top and narrow at the bottom, which conforms to the characteristics of the ship's appearance. The design of the rubber block can avoid rigid collision between the ship and the anti-collision steel block, which not only protects the ship but also reduces damage to the device.

[0018] 4. The present invention has the characteristics of simple structure, easy installation and disassembly, and adopts assembly installation, so that when part of the device structure is damaged or invalid, it can be easily replaced. It also has the characteristics of low cost and can be reused. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0026] The present invention will be further described below in conjunction with the drawings and embodiments:

[0027] See Figure 1-6 。

[0028] The present invention discloses a new type of self-resetting pier anti-collision device, including a pier 1, an external bearing platform 2, a main steel frame 5, an anti-collision steel block 6, a trapezoidal rubber block 7 and a blocking iron plate 11. The external bearing platform 2 is arranged in a circular structure outside the pier 1. The main steel frame 5 is in a "C" shape structure, and its bottom is fixed to the top of the external bearing platform 2 through a fixing bolt 4. The anti-collision steel block 6 and the blocking iron plate 11 are in a square structure, and their tops and bottoms are respectively slidably matched with the inner top and bottom of the main steel frame 5. The inner top and bottom inner ends of the main steel frame 5 are provided with limit blocks 16 integrally formed therewith. The outer end faces of the limit blocks 16 are respectively connected with internal springs 9 between the inner tops and bottoms of the blocking iron plate 11. The outer wall of the anti-collision steel block 6 is connected with the trapezoidal rubber block 7, and energy-absorbing and buffering material layers 13 are provided on the inner wall of the anti-collision steel block 6 and the outer wall of the blocking iron plate 11.

[0029] The energy-absorbing and buffering material layer 13 is a semi-cylindrical energy-absorbing and buffering block arranged in a rectangular array on the inner wall of the anti-collision steel block 6 and the outer wall of the blocking iron plate 11. Preferably, the semi-cylindrical energy-absorbing and buffering blocks on the inner wall of the anti-collision steel block 6 and the outer wall of the blocking iron plate 11 are spaced apart to form a cavity, which is beneficial to the deformation and recovery of the buffer device.

[0030] The outer end of the bottom of the limit block 16 at the inner end of the top of the inner wall of the main steel frame 5 is fixedly connected with one end of a steel wire rope 10. An inverted "L" shaped bracket 15 is fixed on the outer wall of the external bearing platform 2, and a heavy object block 3 is placed on the bracket 15. The steel wire rope 10 is fixedly connected with the top of the heavy object block 3 through a reserved pipeline arranged in the main steel frame 5. A push plate 17 is provided in the middle of the inner wall of the blocking iron plate 11, and a semi-circular semi-circular hole 18 for the steel wire rope 10 to pass through is provided in the middle of the inner end of the push plate 17.

[0031] The external bearing platform 2 is in a right trapezoidal structure with a narrow top and a wide bottom. The bracket 15 is fixed on its outer inclined surface, so that when the heavy object block 3 is reset, it can slide back to its original position along the inclined surface, thereby reducing the load on the bracket 15.

[0032] The trapezoidal rubber block 7 is in a right-angled trapezoidal structure that is wide at the top and narrow at the bottom, which conforms to the characteristics of the ship's appearance. The design of the rubber block can avoid rigid collision between the ship and the anti-collision steel block, which not only protects the ship but also reduces damage to the device. It is made of butyl rubber material and has the advantages of impact resistance and wear resistance, as well as aging resistance.

[0033] Pulleys 8 are installed on the top and bottom of the anti-collision steel block 6. The pulleys 8 roll in cooperation with the inner wall of the main steel frame 5, which can make the anti-collision steel block 6 move and recover better.

[0034] A fixed pulley 12 is provided at the corner of the reserved pipe in the main steel frame 5 for the steel rope 10 to pass through, so that the steel rope 10 can better lift the heavy block 3.

[0035] Construction method: 1) Install the main steel frame near the edge of the pier cap and fix the main steel frame with bolts; 2) Install the steel rope; connect the weights inside the main steel frame and the cap through the pipes and pulleys reserved in the main steel frame; 3) Install the spring, blocking iron plate, energy absorption and buffer material layer, anti-collision steel plate and trapezoidal rubber in sequence. When installing the blocking iron plate, the steel rope must pass through the ring of the blocking iron plate; 4) Finally, install the weight block and connect the weight block and the steel rope to complete the installation.

[0036] Working principle: Under normal conditions, the steel strand 10 just passes through the semicircular hole 18, and when connected to the weight block 3, the steel strand 10 is in a taut state, the upper and lower built-in springs 9 are in a natural state, and the energy-absorbing and buffering material layers 13 on both sides attached to the blocking steel plate 11 and the anti-collision steel block 6 are in natural contact; when a ship collides with a bridge, the ship first contacts the trapezoidal rubber block 7, which protects the device and the ship to a certain extent; the main body formed by the trapezoidal rubber block 7 and the anti-collision steel block 6 moves inward, squeezing the energy-absorbing and buffering material layer 13, which absorbs a certain amount of impact load and continues to push the blocking steel plate 1 1. When the blocking steel plate 11 moves inward, the built-in spring 9 connected thereto absorbs the impact energy, and the steel strand 10 located in the semicircular hole 18 of the blocking steel plate 11 is forced to move inward, pulling the weight block 3 connected thereto, absorbing a large amount of impact energy, thereby achieving the purpose of protecting the bridge and the ship; when the collision is over, the weight block 3 pulls the steel strand 10 downward due to the action of gravity, the built-in spring 9 has a restoring force, and the energy-absorbing buffer material layer 13 has elasticity, so that the blocking steel plate 11 and the anti-collision steel block 6 structure with pulleys 12 installed above and below move outward to return to their original positions, thereby achieving a self-resetting effect.

Any equivalent transformations made using the contents of the present invention's specification and drawings or directly or indirectly applied in related technical fields are also included in the patent protection scope of the present invention.
