Description

Technical Field

[0001] The invention relates to the field of highway safety protection facilities, and in particular to a gravity pile with an elastic supporting structure. Background Art

[0002] At present, most highway reconstruction, expansion or repair construction operations are carried out in a way of operating and constructing at the same time. Temporary guardrails have become an important means of protecting construction areas. At present, the research and development of temporary guardrail products focuses on easy disassembly and assembly, light structure, and is formed by welding thin-walled steel plates. The guardrail is pushed by the vehicle to produce a large deformation to guide the vehicle out, so as to meet the protection requirements of preventing vehicles from rushing into the construction area.

[0003] The existing guardrail segments are connected longitudinally by components, and a large installation gap is often reserved for easy installation. After a vehicle collision, the temporary guardrail will be dragged backward, resulting in a large lateral deformation. When the collision is serious, the lateral deformation of the temporary guardrail can even reach 4m, and the lateral displacement exceeds the width of a lane. Since the back of the temporary guardrail is the construction area, and the reserved gap in some construction areas is small, it is easy to cause accidents in which the temporary guardrail and the vehicle invade the construction area after a vehicle collision. In order to solve this technical problem, some temporary guardrails use stronger steel structures with strong anti-collision capabilities, but the disassembly and assembly are more complicated. In addition, this kind of temporary guardrail with high anti-collision capabilities generally needs to be consolidated with the road surface, which is not convenient for transportation in the on-site construction area, and will also damage the road surface, increasing the maintenance cost. In addition, the removal of some temporary guardrails after consolidation with the road surface is usually destructive, which makes the temporary guardrail non-reusable and causes serious waste of resources.

[0004] Therefore, under the premise of ensuring that the temporary guardrail can be easily disassembled, how to reduce its lateral displacement when it is impacted is a technical problem that needs to be solved urgently. Summary of the invention

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0040] The purpose of the present invention is to provide a gravity pile with an elastic support structure to solve the problems existing in the prior art, so that there is still friction between the gravity pile and the ground during the impact and evacuation process, thereby shortening the lateral displacement of the gravity pile under the action of the impact force, reducing the probability of safety accidents, and protecting the structures and personnel behind the gravity pile.

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] like Figure 1 to Figure 14 As shown, this embodiment provides a gravity pile with an elastic support structure, including a gravity pile body 1, and a receiving cavity is arranged at the bottom of the gravity pile body 1. The receiving cavity can be arranged in a plurality along the arrangement direction of the gravity pile body 1 (the length direction of the gravity pile body 1), or in a plurality along the direction perpendicular to the arrangement direction thereof (the width direction of the gravity pile body 1). An elastic component capable of elastic deformation in the vertical direction (vertical or nearly vertical direction) is arranged in the receiving cavity, and the size of the elastic component is adapted to the size of the receiving cavity. The bottom surface of the elastic component is a rough plane that abuts against the placement surface (usually the ground or road surface) of the gravity pile body 1. In this embodiment, the friction coefficient between the bottom surface of the elastic component (i.e., the above-mentioned rough plane) and the placement surface is not less than 0.8.

[0043] The gravity pile body can be a guardrail, such as a concrete guardrail, a steel structure guardrail, etc., or a roadblock with a large mass, such as a stone ball roadblock, or other objects or devices that may be subjected to a huge impact force.

[0044] When the gravity pile body 1 is impacted by a vehicle, at the moment after the collision, the gravity pile body 1 will be suspended for a period of time under the action of the huge impact force, which may be 1 second or several seconds. Under the action of small resistance and large impact force, even if the suspension process is very short, the gravity pile body 1 may move several meters along the direction of the impact force. However, when the gravity pile body 1 in this embodiment is suspended, a certain distance is generated between the gravity pile body 1 and the placement surface, and there is no friction between the two. At the same time, the compressed elastic component will stretch, and its bottom surface will touch and abut against the placement surface, generating friction. Since the bottom surface of the elastic component is a rough surface, the friction coefficient with the ground is large, so the elastic component will generate a large friction with the ground, shortening the lateral displacement of the gravity pile body 1 under the impact force. Therefore, in this embodiment, by setting an elastic component in the gravity pile body 1, after the gravity pile body 1 is vacated by collision, there is always friction between the gravity pile as a whole and the ground, which can shorten the lateral displacement of the gravity pile under the impact force, reduce the probability of safety accidents, and protect the safety of the structures and personnel behind the gravity pile. For example, when the gravity pile body 1 is a temporary concrete guardrail, it can avoid safety accidents caused by the temporary guardrail and vehicles invading the construction area.

[0045] The elastic component in the gravity pile can have various forms, which are described below with different implementations.

[0046] Embodiment 1:

[0047] like Figure 1 to Figure 3 As shown, in this embodiment, the elastic component includes an elastic body compressed and placed in the accommodating cavity, and the elastic body can be an elastic rubber 2 or other elastic materials. The top of the elastic rubber 2 is connected to the gravity pile body 1, and the bottom surface is a rough surface abutting against the placement surface.

[0048] Elastic rubber 2 is arranged near both ends in the length direction of the gravity pile body 1. When a vehicle collides with the gravity pile body 1, the gravity pile body 1 will leave the road surface and move in the direction of the impact force at the moment of impact. At this time, the elastic rubber 2 rebounds from the compressed state, and the bottom surface of the elastic rubber 2 after rebounding contacts and rubs with the road surface, which increases the sliding friction between the gravity pile body 1 and the road surface and reduces the lateral displacement of the gravity pile body 1. When the vehicle collision is completed, the gravity pile body 1 falls back on the road surface. At this time, the elastic rubber 2 is compressed and retracted into the accommodating cavity of the gravity pile body 1.

[0049] The accommodating cavity should have a certain horizontal cross-sectional area to ensure that the horizontal cross-sectional area of ​​the elastic rubber 2 is large, so as to avoid large bending deformation in the horizontal direction when it rubs against the road surface, and reduce the sliding friction between it and the road surface. At the same time, the accommodating cavity should also have a certain vertical depth, so that when the elastic rubber 2 rebounds and deforms, its larger volume part is still located in the accommodating cavity.

[0050] In order to ensure the stability of the elastic rubber 2 , the top of the elastic rubber 2 can be bonded and fixed to the gravity pile body 1 .

[0051] Embodiment 2:

[0052] like Figures 4 to 6 As shown, in this embodiment, the elastic component includes a compression spring 4 and a friction block, the top and bottom ends of the compression spring 4 are respectively in contact with the bottom of the gravity pile body 1 and the top of the friction block, and the bottom surface of the friction block is a rough surface in contact with the placement surface. The friction block can be a foam friction block 3.

[0053] Compression springs 4 and foam friction blocks 3 are arranged near the two ends in the length direction of the gravity pile body 1. When a vehicle collides with the gravity pile body 1, the gravity pile body 1 will leave the road surface and move in the direction of the impact force at the moment of impact. At this time, the compression spring 4 rebounds from the compressed state and pops out the foam friction block 3. After the foam friction block 3 pops out, its bottom surface contacts and rubs with the road surface, increasing the sliding friction between the gravity pile body 1 and the road surface and reducing the lateral displacement of the gravity pile body 1. When the vehicle collision is completed, the gravity pile body 1 falls back on the road surface. At this time, the compression spring 4 is compressed, and the foam friction block 3 is retracted into the accommodating cavity of the gravity pile body 1.

[0054] After the compression spring 4 rebounds, the foam friction block 3 only partially extends out of the accommodating cavity, but not fully extended.

[0055] Embodiment 3:

[0056] like Figure 7 to Figure 10 As shown, in this embodiment, the accommodating cavity is a side open structure, that is, in the width direction of the gravity pile body 1, the accommodating cavity is located at the end, and its opening is connected to the external environment. The elastic component includes a support body 5, and an elastic body is arranged at the bottom end of the support body 5, and the elastic body is an elastic rubber 2. At the same time, an elastic body can also be arranged at the top end of the support body 5. The elastic body located at the top end of the support body 5 can be connected to the gravity pile body 1 by bonding.

[0057] In this embodiment, the support body 5 has an adjustable function, and can be a telescopic rod, an electric push rod or other types of support structures that can adjust and lock the height. In this embodiment, the support body 5 includes a top fixing block 6, two upper connecting rods 7, two lower connecting rods 8, a bottom fixing block 9 and a screw 10, wherein the top ends of the two upper connecting rods 7 are hinged to the top fixing block 6, and the bottom ends are respectively hinged to the top ends of the two lower connecting rods 8 through the first hinge axis and the second hinge axis, and the bottom ends of the two lower connecting rods 8 are both hinged to the bottom fixing block 9, and the top ends of the top fixing block 6 and the bottom ends of the bottom fixing block 9 are both provided with an elastic body, and the support body 5 can select an elastic rubber 2; the screw 10 is rotatably arranged on the first hinge axis, but the axial direction of the screw 10 is limited, and the other end of the screw 10 passes through the second hinge axis and is threadedly matched with the threaded hole provided on the second hinge axis. By rotating the screw 10, the horizontal distance between the first hinge axis and the second hinge axis can be adjusted, thereby adjusting the overall height of the support body 5.

[0058] The gravity pile body 1 has a receiving cavity at the bottom near the two end positions in the length direction, and a support body 5 is installed in the receiving cavity. The height of the support body 5 is adjusted so that the top end of the support body 5 is against the gravity pile body 1 and the bottom end is against the road surface. When a vehicle collides with the gravity pile body 1, the gravity pile body 1 will leave the road surface and move in the direction of the impact force at the moment of impact. At this time, the elastic rubber 2 above and below the support body 5 rebounds from the compressed state, and the bottom surface of the elastic rubber 2 after rebounding at the bottom contacts and rubs with the road surface, which increases the sliding friction between the gravity pile body 1 and the road surface and reduces the lateral displacement of the gravity pile body 1. When the vehicle collision is completed, the gravity pile body 1 falls back on the road surface, and the upper and lower elastic rubbers 2 are compressed again.

[0059] Embodiment 4:

[0060] like Figure 11 to Figure 14 As shown, in this embodiment, in addition to the accommodating cavity, a groove is also provided at the bottom of the gravity pile, and an elastic body is provided in the groove, and the elastic body can be an elastic rubber 2. The support body 5 includes a top fixing block 6, two upper connecting rods 7, two lower connecting rods 8 and a bottom fixing block 9. The top fixing block 6 is connected to the gravity pile body 1, the top ends of the two upper connecting rods 7 are hinged to the top fixing block 6, and the bottom ends are respectively hinged to the top ends of the two lower connecting rods 8 through the first hinge shaft and the second hinge shaft, and the bottom ends of the two lower connecting rods 8 are both hinged to the bottom fixing block 9, and the bottom end of the bottom fixing block 9 is provided with an elastic body; the top fixing block 6 and the bottom fixing block 9 are both provided with magnetic poles of the same polarity, and the two magnetic poles are arranged opposite to each other.

[0061] The gravity pile body 1 has a receiving cavity at the bottom near the two end positions in the length direction, and a support body 5 is installed in the receiving cavity, the top of the support body 5 is against the gravity pile body 1, and the bottom is against the road surface. When a vehicle collides with the gravity pile body 1, the gravity pile body 1 will leave the road surface and move along the direction of the impact force at the moment of impact. At this time, the elastic rubber 2 inside the groove rebounds from the compressed state, and its bottom surface contacts and rubs with the road surface. The distance between the top fixing block 6 and the bottom fixing block 9 becomes larger under the action of the repulsive force of the two magnetic poles, and the bottom surface of the bottom fixing block 9 contacts and rubs with the road surface, thereby increasing the sliding friction between the gravity pile body 1 and the road surface and reducing the lateral displacement of the gravity pile body 1. When the vehicle collision is completed, the gravity pile body 1 falls back on the road surface, and the elastic rubber 2 and the support body 5 are compressed again.

[0062] As an implementation mode, the magnetic poles in this embodiment are all electromagnets 11 , and the opposite ends of the two electromagnets 11 have the same polarity; the gravity pile body 1 is also provided with a battery 12 connected to the electromagnet 11 via a wire 14 .

[0063] In this embodiment, the accommodating cavity is also provided with a sensor 13 for sensing the separation of the gravity pile body 1 from the road surface. The sensor 13 is used to control the on-off of the circuit between the battery 12 and the electromagnet 11. At the same time, the battery 12 also supplies power to the sensor 13 through the wire 14. When the sensor 13 senses that the gravity pile body 1 is separated from the road surface, it controls the circuit between the battery 12 and the electromagnet 11 to be turned on, and both electromagnets 11 are energized to generate repulsive force, so that the bottom fixed block 9 is in contact with the road surface and rubs. When the Chongli pile body falls back on the road surface, the sensor 13 cuts off the circuit between the battery 12 and the electromagnet 11 to avoid the circuit being continuously turned on and consuming the electric energy of the battery 12.

[0064] In order to charge the storage battery 12 , a solar panel is disposed on the top of the gravity pile body 1 in this embodiment, and the solar panel is electrically connected to the storage battery 12 .

[0065] Embodiments 3 and 4 are suitable for large gravity pile bodies 1. The support body 5 is used to support the gravity pile body 1, which can reduce the setting height of the elastic body. The support body 5 can support the gravity pile body 1 by using the relatively large support stiffness.

[0066] Embodiment 5:

[0067] like Figure 15 to Figure 17As shown, an elastic inflatable bag 15 is arranged near the two ends in the length direction of the gravity pile body 1, and the elastic inflatable bag 15 is inflated by the leaking inflation port 16, so that the elastic inflatable bag 15 is in a high-pressure state. The elastic inflatable bag 15 is located in the accommodating cavity under the limiting effect of the gravity pile body 1, which is not enough to overcome the gravity of the gravity pile body 1 and bounce it up. When a vehicle collides with the gravity pile body 1, the gravity pile body 1 will leave the road surface and move along the direction of the impact force when it is hit. At this time, the elastic inflatable bag 15 expands under the action of high-pressure gas, and is exposed from the bottom of the accommodating cavity. The bottom surface of the expanded elastic inflatable bag 15 contacts and rubs with the road surface, which increases the sliding friction between the gravity pile body 1 and the road surface, and reduces the lateral displacement of the gravity pile body 1. After the collision, the gravity pile body 1 may not be completely fitted with the road surface after falling back because of the elastic inflatable bag 15 at the bottom. The elastic inflatable bag 15 should be deflated first, and after the bottom of the gravity pile body 1 is completely in contact with the road surface again, the elastic inflatable bag 15 is inflated with high-pressure gas to generate sufficient pressure between the elastic inflatable bag 15 and the road surface, so that it can be used reciprocatingly.

[0068] As an implementation manner, it also includes a cover plate 17 fixed to the gravity pile body 1 by means of anchor bolts 18 , and an inflation port 16 is provided on the cover plate 17 .

[0069] As an embodiment, the accommodating cavity is configured in a special shape, with its bottom located in the middle of the gravity pile body 1 in the width direction, and its top blocked by a cover plate 17. When in use, the elastic inflatable bag 15 is placed in the accommodating cavity in an uninflated and relaxed state, and its inflation port 16 is fixed on the cover plate 17 and exposed.

[0070] In this embodiment, the elastic airbag 15 is an elastic rubber airbag.

[0071] Adaptive changes made according to actual needs are all within the protection scope of the present invention.

[0072] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
