Description

Technical Field

[0001] The present invention relates to the technical field of safety protection, and in particular to a novel anti-collision device. Background Art

[0002] In scenarios such as road traffic and bridge and shipping, it's common for cars or ships to collide with fixed structures due to operational errors or unexpected events, resulting in serious property damage and even casualties. For example, a car traveling at high speeds can damage guardrails or break railings, leading to capsizing, falling into the water, or even rolling over. A ship colliding with a bridge pier during navigation often damages the pier structure and can even cause serious consequences such as fractures in the superstructure or falling beams. Currently, to prevent such accidents, anti-collision devices are installed in areas such as highways and bridges. These devices rely on their own structural strength, stiffness, and ductility to block cars or ships, reducing the destructive force of the impact.

[0003] The basic function of an anti-collision device is to cushion the impact force caused by a collision of a vehicle or ship through structural energy absorption, force transmission or direction guidance, thereby protecting key structures such as bridge piers and guardrails and reducing accident losses. There is currently a bridge pier anti-collision device, including: an anti-collision ring, a buffer rubber block, a positioning rod and a rotating guide cylinder. The anti-collision ring is arranged around the outside of the bridge pier, and multiple buffer rubber blocks are fixed on the inside of the anti-collision ring, facing the bridge pier. A plurality of positioning rods are arranged in a circumferential array on the outer wall of the anti-collision ring, and a rotating guide cylinder is fixed to the outside of the positioning rod. When a ship collides, the rotating guide cylinder preferentially contacts the hull to guide its deflection. At the same time, the buffer rubber block on the inside of the anti-collision ring is squeezed and deformed to absorb the impact force. However, during the buffering process of this anti-collision device, the anti-collision ring will directly contact the bridge pier. Although the rotating guide cylinder can offset part of the impact force, there is still too much impact force directly acting on the bridge pier, which can easily cause damage to the bridge pier structure. Summary of the Invention

[0004] In view of this, the present invention provides a novel anti-collision device to reduce the direct impact force on the bridge pier and alleviate the structural damage problem of the bridge pier.

[0005] In a first aspect, the present invention provides a novel anti-collision device, comprising:

[0006] A track mechanism, the track mechanism being arranged on the outer wall of the protected object;

[0007] A plurality of sliding mechanisms, wherein the plurality of sliding mechanisms are slidably arranged on the track mechanism;

[0008] A plurality of rotating mechanisms, each of the sliding mechanisms is provided with the rotating mechanism, the rotating mechanism comprising: a rotating shaft and a rotating drum, the rotating shaft being connected to the sliding mechanism, the rotating drum being rotatably sleeved on the rotating shaft;

[0009] When any of the rotating mechanisms is impacted by external force, the rotating drum of the rotating mechanism rotates, and at the same time the rotating shaft drives the sliding mechanism connected thereto to slide, thereby driving the adjacent rotating drum to rotate and the sliding mechanism to slide, thereby weakening the impact force.

[0010] Beneficial effects

[0011] By installing a track mechanism on the outer wall of the protected object, and slidingly mounting multiple sliding mechanisms on the track mechanism, each sliding mechanism is equipped with a rotatable rotating mechanism. When the protected object is impacted, the impact force first acts on the rotating drum, causing it to rotate. This, in turn, drives the sliding mechanisms on the track via the rotating shaft, thus forming a "rotation-slide-interlocking" buffer mechanism. Because adjacent rotating and sliding mechanisms are driven synchronously, the impact force is diffused and dispersed along multiple mechanism paths, significantly reducing the concentrated impact force and alleviating the instantaneous impact load on the protected object. This achieves the effect of using softness to overcome hardness, similar to the Tai Chi silk-winding technique, improving the protected object's collision resistance and safety.

[0012] In an optional embodiment, the interior of the drum has a cavity, and the cavity is filled with energy-absorbing filler.

[0013] Beneficial effects

[0014] The cavity is filled with energy-absorbing filler, so that when the rotating mechanism is hit by external force, in addition to relying on the rotation of the drum and the linkage of the sliding mechanism to weaken the impact force, the deformation energy absorption characteristics of the filler can also be used to further absorb the impact energy.

[0015] The energy-absorbing filler will undergo plastic deformation or compression when squeezed, which can convert part of the mechanical energy into internal energy, further reducing the impact of the impact force on the protected object and improving the buffering effect of the anti-collision device.

[0016] In an optional embodiment, a plurality of wear-resistant protrusions are provided on the outer side wall of the rotating drum.

[0017] Beneficial effects

[0018] Providing wear-resistant protrusions can significantly improve the wear resistance and impact resistance of the outer surface of the drum. At the same time, the protrusion structure can form discontinuous point contact when it comes into contact with the impacting object, which helps to disperse energy consumption through multi-point local deformation.

[0019] In an optional embodiment, the track mechanism includes: a sliding beam, multiple anchoring members and multiple pillars, the multiple anchoring members are arranged at intervals along the outer wall of the protected object, each pillar is connected to one anchoring member, and the sliding beam is arranged on the top surface of the pillar.

[0020] In an optional embodiment, a plurality of insertion holes are opened on the outer wall of the protected object, one end of the anchoring member is inserted into the insertion hole, and structural adhesive is filled between the inner wall of the insertion hole and the outer wall of the anchoring member.

[0021] Beneficial effects

[0022] Structural adhesive can enhance the bonding strength between the socket and the anchor, and can also absorb small vibrations and stresses to a certain extent, preventing the anchor from loosening or falling off due to long-term stress or environmental changes.

[0023] In an optional embodiment, the sliding mechanism includes: a sliding plate and a clamp, the clamp is arranged on one side of the sliding plate, the sliding plate and the clamp are combined to form a slide groove, the sliding beam is slidably connected to the slide groove, and the bottom ends of the sliding plate and the clamp have a clamping groove suitable for accommodating the pillar, and the top surface of the slide groove is provided with a low-friction slide plate.

[0024] Beneficial effects

[0025] The low-friction slide helps to reduce the friction resistance of the sliding mechanism during the sliding process on the track mechanism, improve the response sensitivity and sliding efficiency of the sliding mechanism when it is impacted, enable the impact pressure to be transmitted and dispersed more smoothly through the sliding mechanism, and enhance the buffering performance of the anti-collision device.

[0026] In an optional embodiment, the track mechanism is a linear structure, a circular structure, or a circular-straight composite structure, and when the track mechanism is a non-closed structure, brake pins are provided at both ends of the track mechanism.

[0027] In an optional embodiment, the width of the sliding groove is greater than the width of the sliding beam, the width of the sliding beam is greater than the width of the clamping groove, and the width of the clamping groove is greater than the width of the pillar.

[0028] In an optional embodiment, the track mechanism is a circular structure or a circular-straight composite structure, and the width of the engaging groove is greater than the sum of the width of the pillar and the sagittal height of the sliding plate across the pillar.

[0029] In an optional embodiment, two groups of the rotating mechanisms are provided on each of the sliding mechanisms, and a chamfer is provided on a side of the sliding mechanism close to the protected object. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0046] Example 1

[0047] The following combination Figures 1 to 5 , describing embodiments of the present invention.

[0048] According to an embodiment of the present invention, on the one hand, a new anti-collision device is provided, comprising: a track mechanism 1, a plurality of sliding mechanisms 3, and a plurality of rotating mechanisms 4, wherein the track mechanism 1 is arranged on the outer wall of the protected object 2; the plurality of sliding mechanisms 3 are slidably arranged on the track mechanism 1; each sliding mechanism 3 is provided with a rotating mechanism 4, and the rotating mechanism 4 comprises: a rotating shaft 41 and a rotating drum 42, the rotating shaft 41 being connected to the sliding mechanism 3, and the rotating drum 42 being rotatably sleeved on the rotating shaft 41;

[0049] When any rotating mechanism 4 is hit by an external force, the rotating drum 42 of the rotating mechanism 4 rotates, and the rotating shaft 41 drives the sliding mechanism 3 connected thereto to slide, thereby driving the adjacent rotating drum 42 to rotate and the sliding mechanism 3 to slide, thereby weakening the impact force.

[0050] Specifically, the protected object 2 can be a column, wall, or beam-shaped entity. The track mechanism 1 is mounted on the outer wall of the protected object 2, extending along the outer contour of the protected object 2 to accommodate the protection requirements of different structures of the protected object 2. Multiple sliding mechanisms 3 are slidably mounted on the track mechanism 1 and are capable of moving along the track mechanism 1. Each sliding mechanism 3 is mounted on a rotating mechanism 4. A rotating shaft 41 is fixedly connected to the top surface of the sliding mechanism 3 on the side away from the protected object 2, and a rotating drum 42 is rotatably mounted on the outside of the rotating shaft 41.

[0051] When a vehicle or ship collides with the novel anti-collision device, one or more rotating mechanisms 4 are first impacted by an external force. The rotating drum 42 of this rotating mechanism 4 rotates first, causing the rotating shaft 41 to shift as the rotating drum 42 rotates, thereby driving the connected sliding mechanisms 3 to slide along the track. Simultaneously, because the sliding mechanisms 3 are in contact with each other via the track mechanism 1, the impacted sliding mechanism 3 will drive the movement of adjacent sliding mechanisms 3 during the sliding process, causing the rotating drum 42 on the adjacent sliding mechanisms 3 to also rotate, thereby creating a coordinated response effect among multiple sliding mechanisms 3. The synergistic effect of the rotating drum 42's rotation and the sliding mechanism 3's displacement diffuses and weakens the impact force among the multiple sliding mechanisms 3, reducing the risk of the impact force being concentrated at a single point or area on the protected object 2 and improving the anti-collision device's cushioning capacity and stability.

[0052] The anti-collision device employs multiple sliding mechanisms 3 mounted on a track mechanism 1, with a rotating mechanism 4 attached to each sliding mechanism 3. This ensures that when any rotating mechanism 4 is impacted by an external force, it immediately triggers the rotation of the drum 42, driving the sliding mechanism 3 to slide, thereby achieving a coordinated buffering response for the multiple sliding mechanisms 3. This "rotation-slip-diffusion" synergistic buffering mechanism achieves a Tai Chi-like effect of overcoming rigidity with softness, converting primarily radial impact forces into primarily tangential frictional forces. This reduces the risk of impact and damage to the protected object 2, minimizing deformation and secondary damage, and effectively dispersing the concentrated impact force.

[0053] In one embodiment, the drum 42 has a cavity therein, and the cavity is filled with energy-absorbing filler 43 .

[0054] Specifically, an annular cavity is formed inside the rotating drum 42, and the cavity is filled with energy-absorbing filler 43. Optionally, the filler can be foamed aluminum, polyurethane foam material, rubber particle compound or other materials with good energy absorption performance.

[0055] When the rotating mechanism 4 is struck by an external force, the impact force first acts on the rotating drum 42, causing it to rotate while the sliding mechanism 3 slides on its track. During this process, the energy-absorbing filler 43 inside the rotating drum 42 is compressed or sheared due to inertia and the external force, causing it to undergo plastic or elastic deformation, converting some of the impact energy into internal energy for dissipation. This energy absorption process, working in conjunction with the rotation-sliding linkage energy dissipation mechanism, further reduces the impact energy and enhances the overall protective capability of the anti-collision device.

[0056] In one embodiment, a plurality of wear-resistant protrusions are provided on the outer wall of the drum 42 .

[0057] Specifically, a plurality of wear-resistant protrusions are evenly arranged on the outer wall of the rotating drum 42. The wear-resistant protrusions are integrally formed with the rotating drum 42 or are adhered to the outer surface of the rotating drum 42 after post-processing. The cross-section of the protrusions can be a hemispherical or conical structure, and the material can be high-strength rubber, wear-resistant engineering plastics or metal composite materials to enhance its wear resistance.

[0058] When an impacting object contacts the wear-resistant projections on the drum 42, these projections provide a buffering space during the initial impact, absorbing some of the initial impact force. Furthermore, the wear-resistant projections change the contact state during impact, shifting from surface contact to multi-point contact. This helps disperse the impact force and reduces the impact stress per unit area of the drum 42.

[0059] In one embodiment, the track mechanism 1 includes: a sliding beam 11, multiple anchoring members 12 and multiple pillars 13. The multiple anchoring members 12 are arranged at intervals along the outer wall of the protected object 2. Each pillar 13 is connected to an anchoring member 12. The sliding beam 11 is arranged on the top surface of the pillar 13.

[0060] Specifically, multiple anchors 12 are fixed at intervals to the outer wall of the protected object 2. The bottom end of each support 13 is connected to an anchor 12. The sliding beam 11 is a plate-type sliding beam 11. The top end of the support 13 is connected to the bottom end of the sliding beam 11, so that the sliding beam 11 forms a continuous sliding path along the outer contour of the protected object 2. The width of the sliding beam 11 is D1, and the width of the support 13 is d1, and D1>d1.

[0061] The anchoring member 12 can be a metal insert, expansion bolt, or welded connector, and can be flexibly selected based on the material and structure of the protected object 2 to ensure the anchoring effect. The support 13 is preferably made of high-rigidity steel or composite materials with good load-bearing capacity and impact resistance, and is used to firmly support the sliding beam 11.

[0062] In one embodiment, a plurality of insertion holes 21 are formed on the outer wall of the protected object 2 , one end of the anchor 12 is inserted into the insertion hole 21 , and structural adhesive 22 is filled between the inner wall of the insertion hole 21 and the outer wall of the anchor 12 .

[0063] This method is generally applicable to existing protected objects 2, such as columns, walls, and beams. Specifically, multiple receptacles 21 are formed along the circumference of the outer wall of the protected object 2. Structural adhesive 22 is then filled into these receptacles 21. The diameter of the receptacles 21 is slightly larger than the width of the anchoring element 12, and each receptacle 21 can accommodate an anchoring element 12 for bonding. Structural adhesive 22 is made from a high-strength epoxy or polyurethane adhesive, offering excellent bond strength, aging resistance, and environmental resistance, ensuring the stability of the anchoring connection over long periods of use.

[0064] Furthermore, the inner wall of the insertion hole 21 can be roughened or provided with a light texture to increase the adhesion of the colloid and further enhance the anchoring effect.

[0065] In other embodiments, if the protected object 2 is not a built building, the anchoring member 12 may also be formed integrally with the construction of the protected object 2 .

[0066] In one embodiment, the sliding mechanism 3 includes: a sliding plate 31 and a clamp 32, the clamp 32 is arranged on one side of the sliding plate 31, the sliding plate 31 and the clamp 32 are combined to form a slide groove, the sliding beam 11 is slidingly connected to the slide groove, and the bottom ends of the sliding plate 31 and the clamp 32 have a clamping groove suitable for accommodating the pillar 13, and the top surface of the slide groove is provided with a low-friction slide plate 33.

[0067] Specifically, the sliding plate 31 is slidably clamped on the top surface of the sliding beam 11, and a connecting portion for installing a clamp 32 is provided on one side thereof. The clamp 32 is an L-shaped structure, one end of the clamp 32 is fixedly connected to the sliding plate 31, and the other end is buckled with the sliding beam 11, thereby enclosing a sliding groove together with the sliding plate 31.

[0068] The sliding plate 31 can be made of high-strength engineering plastic or metal material, which has good rigidity and wear resistance; the clamp 32 can be made of high-elasticity material to enhance its covering and fitting ability while also facilitating installation and removal.

[0069] The low-friction slide plate 33 is fixedly mounted on the top surface of the slide groove of the sliding mechanism 3 and is in direct contact with the top surface of the slide beam 11. Optionally, the slide plate can be made of polytetrafluoroethylene (PTFE), ultra-high molecular weight polyethylene (UHMWPE) or other engineering plastic materials with excellent friction reduction properties.

[0070] Optionally, the low-friction slide 33 can be fixedly connected to the top surface of the slide groove by screws, riveting or gluing. The surface of the low-friction slide 33 is smooth and flat, which can significantly reduce the friction coefficient between the sliding mechanism 3 and the sliding beam 11.

[0071] In one embodiment, the track mechanism 1 is a linear structure 23 or a circular structure 24 or a circular-straight composite structure 25 , and when the track mechanism 1 is a non-enclosed structure, brake tumblers 14 are provided at both ends of the track mechanism 1 .

[0072] In this embodiment, the protected object 2 is a linear column, wall or beam structure. To prevent the sliding mechanism 3 from excessively sliding along the slide beam 11 or detaching from the slide beam 11 when driven by impact, brake tumblers 14 are provided at both ends of the track mechanism 1.

[0073] Brake bolts 14 are respectively installed at both ends of the sliding beam 11. The two brake bolts 14 fix the two sliding mechanisms 3 on the sliding beam 11 to prevent the remaining sliding mechanisms 3 on the sliding beam 11 from slipping out. At the same time, the relationship between the sliding mechanism 3 and the track mechanism 1 satisfies d1 < d2 < D1, and the rotating mechanism 4 is arranged at the edge of the top surface of the sliding mechanism 3 away from the protected object 2.

[0074] In other embodiments, if the track mechanism 1 is a non-closed circular structure 24 or a circular-straight composite structure 25 that is not connected end to end, brake bolts 14 also need to be provided at both ends.

[0075] In other embodiments, if the track mechanism 1 is a closed circular structure 24 or a circular-straight composite structure 25, then brake bolts 14 do not need to be provided.

[0076] In one embodiment, the width of the chute is greater than the width of the sliding beam 11, the width of the sliding beam 11 is greater than the width of the clamping groove, and the width of the clamping groove is greater than the width of the support column 13.

[0077] The width of the chute is D2, and the width of the clamping groove between the sliding plate 31 and the clamp 32 is d2. To enable the sliding mechanism 3 to slide freely along the sliding beam 11, appropriate gaps can be left on the inner surfaces of the chute and the clamping groove, that is, D2 > D1 and d2 > d1, to ensure that the sliding mechanism 3 has a small frictional resistance and does not get stuck during the sliding process.

[0078] In another embodiment, the sliding beam 11 can also be an annular cylindrical sliding beam 11, and the clamp 32 is set as a circular clamp 32, and the inner arc curvature of the clamp 32 matches the outer diameter of the sliding beam 11.

[0079] Working process: When an external impact object (such as a vehicle or a ship) hits the protected object 2 at a certain speed, the first thing it touches is the rotating cylinder 42 in the rotating mechanism 4. The impact force acts on the rotating cylinder 42, causing it to rotate around the rotating shaft 41. Since the rotating shaft 41 is fixedly connected to the sliding mechanism 3, the rotation of the rotating cylinder 42 will drive the sliding mechanism 3 to slide along the track mechanism 1.

[0080] As the sliding mechanism 3 slides, the adjacent sliding mechanisms 3 are pulled to move under the action of structural coupling, and the rotating mechanisms 4 thereon also rotate correspondingly, thus forming a process of linkage response of multiple sliding mechanisms 3 and rotating mechanisms 4. The linkage response between multiple sliding mechanisms 3 not only extends the force application path but also consumes part of the impact energy through the relative movement between the sliding mechanisms 3 to achieve impact force buffering.

[0081] The rotating cylinder 42 is filled with energy-consuming filler 43. During the impact process, the energy-consuming filler 43 is synchronously compressed and deformed to further absorb the impact energy; the wear-resistant protrusions provided on the surface of the rotating cylinder 42 can also disperse part of the impact stress during the rotational contact process.

[0082] Embodiment 2

[0083] The difference between this embodiment and Embodiment 1 is that the track mechanism 1 is a circular structure 24 or a circular and straight composite structure 25, the width of the clamping groove is greater than the sum of the width of the support column 13 and the sagitta of the sliding plate 31 straddling the support column 13, and other structures are the same as those in Embodiment 1, so this embodiment will not be described again.

[0084] As Figures 6 and 7 shown, in this embodiment, the protected object 2 is a circular pier or a circular and straight composite column with an arc-shaped outer contour. To achieve a more uniform impact response and energy diffusion of the anti-collision device, a set of rotating mechanisms 4 are provided on each sliding mechanism 3, and no braking bolts 14 need to be provided on the track mechanism 1.

[0085] In addition, when the protected object 2 is a circular pier, d2 > d1 and d2 < D1 are satisfied between the sliding mechanism 3 and the track mechanism 1.

[0086] When the protected object 2 is a circular pier or a circular and straight composite column with an arc-shaped outer contour, when the sliding plate 31 is located at the arc-shaped contour section, the sagitta of the sliding plate 31 straddling the support column 13 is f1, and d1 + f1 < d2 < D1 is satisfied between the sliding mechanism 3 and the track mechanism 1.

[0087] Embodiment 3

[0088] The difference between this embodiment and Embodiment 2 is that two sets of rotating mechanisms 4 are provided on each sliding mechanism 3, and a chamfer 34 is provided on the side of the sliding mechanism 3 close to the protected object 2. Other structures are the same as those in Embodiment 2, so this embodiment will not be described.

[0089] As Figures 8 and 9 shown, two sets of rotating mechanisms 4 are provided on each sliding mechanism 3, and the two sets of rotating mechanisms 4 are distributed front and back along the length direction of the sliding mechanism 3, so as to achieve synchronous response in the front and back directions when the protected object 2 is impacted. Each set of rotating mechanisms 4 includes a rotating shaft 41 and a rotating cylinder 42, which are arranged independently of each other and do not interfere with each other.

[0090] When the protected object 2 is a circular pier, d2 > d1 and d2 < D1 are also satisfied between the sliding mechanism 3 and the track mechanism 1.

[0091] When the protected object 2 is a circular and straight composite column with an arc-shaped outer contour, when the sliding plate 31 is located at the arc-shaped contour section, the sagitta of the sliding plate 31 straddling the support column 13 is f1, and d1 + f1 < d2 < D1 is also satisfied between the sliding mechanism 3 and the track mechanism 1, so that the sliding mechanism 3 can slide freely and continuously on the straight section and the curve section of the track mechanism 1.

[0092] The chamfer 34 is provided at an edge of the sliding plate 31 or the clamp 32 close to the protected object 2 . The cross-sectional shape of the chamfer 34 can be a slope or an arc transition structure.

[0093] The chamfer 34 can reduce the friction or interference caused by the contact between the sliding mechanism 3 and the outer wall of the protected object 2 due to the contact between the sharp edges. When the sliding mechanism 3 slides along the track mechanism 1, the chamfer 34 can provide a flexible transition interface to prevent jamming, scratching or unstable sliding during the sliding process, thereby improving the smoothness of the sliding of the sliding mechanism 3.

[0094] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations are all within the scope defined by the appended claims.
