Description

Technical Field

[0001] The utility model relates to an anti-collision device, in particular to an anti-collision device for a bridge. Background Art

[0002] Bridges generally refer to structures built on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that are built to cross mountain streams, poor geology, or meet other transportation needs to make travel more convenient. Bridges are generally composed of superstructures, substructures, supports, and ancillary structures. The superstructure, also known as the bridge span structure, is the main structure for crossing obstacles; the substructure includes abutments, piers, and foundations; the supports are force transmission devices installed at the supporting locations of the bridge span structure and the piers or abutments; the ancillary structures refer to the bridgehead slabs, conical slope protection, revetments, diversion projects, etc.

[0003] Existing technologies for bridge collision avoidance include setting up piers outside the piers, filling cofferdams with sand and gravel, etc., to reduce the risk of collision by adding obstacles around the bridge, or installing infrared monitoring and voice warning systems, laser ranging alarm systems or satellite navigation area systems on the bridge to track and detect moving ship targets and accurately determine the safe distance.

[0004] However, the prior art has the following technical problems:

[0005] (1) During use, the existing bridge anti-collision technology has a poor anti-collision effect, which makes the bridge piers easily damaged when hit.

[0006] (2) The existing bridge anti-collision device has a complicated installation process, which not only wastes a lot of installation time but also increases the difficulty of subsequent maintenance.

[0007] Therefore, there is an urgent need for a bridge anti-collision device to solve the technical problems existing in the above-mentioned prior art. Summary of the invention

[0008] The utility model overcomes the shortcomings of the prior art and provides a bridge anti-collision device.

[0009] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a bridge anti-collision device, including: a bridge column, a base, a protective pad, a buffer mechanism, a limiting mechanism, and a limiting column;

[0010] The buffer mechanism is located on both sides of the bridge column, and the buffer mechanism includes: a buffer plate, a buffer rod, and a fixing pin for installing the limiting mechanism; the buffer rod is used to limit the distance between the buffer plate and the bridge column;

[0011] The limiting mechanism comprises: a limiting plate, a latching tooth, and a guide rail; one end of the limiting plate is provided with the latching tooth, both ends of the buffer plate are provided with a latching groove capable of accommodating the latching tooth, and the limiting column is provided with a guide groove matched with the guide rail;

[0012] One end of the buffer rod is fixed to the outer wall of the bridge column through a mounting seat.

[0013] In a preferred embodiment of the utility model, the buffer rod includes: a sleeve and a retractable rod; the sleeve is sleeved with the retractable rod, the end of the sleeve is connected to the bridge column, the end of the retractable rod is connected to the buffer plate, and a spring connected to the retractable rod is arranged in the sleeve.

[0014] In a preferred embodiment of the utility model, the latching teeth are provided with a fixing hole, and the fixing pin passes through the fixing hole to connect the buffer plate with the limiting plate.

[0015] In a preferred embodiment of the utility model, protrusions are arranged on the top and the bottom of the guide rail, and grooves matching the protrusions are arranged in the guide groove.

[0016] In a preferred embodiment of the present invention, the outer surface of the limiting plate has an arc of 15° to 35°.

[0017] In a preferred embodiment of the present invention, the buffer mechanism and the limiting column are both made of stainless steel.

[0018] In a preferred embodiment of the utility model, the retractable rod is completely extended out of the sleeve, the outermost wall of the buffer mechanism is located outside the outermost wall of the base, the retractable rod is completely retracted into the sleeve, and the outermost wall of the buffer mechanism is on the same horizontal plane as the outermost wall of the base.

[0019] In a preferred embodiment of the present invention, the spacing between the limit plates located on both sides of the bridge column is 50 to 80 cm.

[0020] In a preferred embodiment of the present invention, the distance between each two adjacent buffer plates is 10 to 20 cm.

[0021] In a preferred embodiment of the present invention, the base is located at the bottom of the bridge column, and the protective pad is fixed on the four sides and four corners of the base.

[0022] The utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0023] (1) Through the cooperation between the buffer mechanism and the limit mechanism, when a ship accidentally hits a bridge, it can first contact the buffer plate, and then the buffer rod can slow down the impact force, avoiding direct impact on the bridge column. At the same time, the cooperation between the guide rail of the limit mechanism and the limit column can limit the moving distance of the buffer plate through the sliding distance, preventing it from excessive deformation or falling off, thereby enhancing the safety protection effect, and can also effectively reduce the impact force and reduce the damage to the bridge structure.

[0024] (2) When a ship accidentally hits a bridge, the impact force will first be transmitted to the buffer plate, which will then cause the retractable rod to move in the sleeve. In this process, the spring will play a role in buffering and shock absorption, converting part of the impact force into the compression potential energy of the spring, thereby significantly reducing the direct impact on the bridge column and protecting the bridge structure.

[0025] (3) When the retractor is fully extended, the outer wall of the buffer mechanism will extend beyond the outer wall of the base, forming an additional protective layer. This increases the contact area between the anti-collision device and the potential impact object, thereby improving the protective effect and reducing the possibility of direct impact with the bridge column.

[0036] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0037] like Figure 1 As shown, a bridge anti-collision device comprises: a bridge column 1, a base 2, a protective pad 3, a buffer mechanism 4, a limiting mechanism 5, and a limiting column 6;

[0038] The buffer mechanism 4 is located on both sides of the bridge column 1, and the buffer mechanism 4 includes: a buffer plate 4.1, a buffer rod 4.2, and a fixing pin 4.3 for installing the limiting mechanism 5; the buffer rod 4.2 is used to limit the distance between the buffer plate 4.1 and the bridge column 1;

[0039] like Figure 2 and Figure 3 As shown, the limiting mechanism 5 includes: a limiting plate 5.1, a latch tooth 5.2, and a guide rail 5.4; one end of the limiting plate 5.1 is provided with a latch tooth 5.2, both ends of the buffer plate 4.1 have a slot capable of accommodating the latch tooth 5.2, and the limiting column 6 has a guide groove matching the guide rail 5.4; one end of the buffer rod 4.2 is fixed to the outer wall of the bridge column 1 through a mounting seat 7.

[0040] Through the cooperation between the buffer mechanism 4 and the limiting mechanism 5, when a vehicle or ship accidentally hits the bridge, it can first contact the buffer plate 4.1, and the buffer rod 4.2 can reduce the impact force to avoid direct impact on the bridge column 1. At the same time, the cooperation between the guide rail 5.4 of the limiting mechanism 5 and the limiting column 6 can limit the moving distance of the buffer plate 4.1 through the sliding distance to prevent it from excessive deformation or falling off, thereby enhancing the safety protection effect, and can also effectively reduce the impact force and reduce the damage to the bridge structure.

[0041] like Figure 4 As shown, the buffer rod 4.2 includes: a sleeve 4.2.1 and a retractable rod 4.2.2; the sleeve 4.2.1 is sleeved with the retractable rod 4.2.2, the end of the sleeve 4.2.1 is connected to the bridge column 1, the end of the retractable rod 4.2.2 is connected to the buffer plate 4.1, and a spring 4.2.3 connected to the retractable rod 4.2.2 is arranged in the sleeve 4.2.1. The spring 4.2.3 will play a role in buffering and shock absorption, converting part of the impact force into the compression potential energy of the spring 4.2.3, thereby significantly reducing the direct impact on the bridge column 1 and playing a role in protecting the bridge structure.

[0042] The latch 5.2 has a fixing hole 5.3, and the fixing pin 5.2 passes through the fixing hole 5.3 to connect the buffer plate 4.1 with the limit plate 5.1. The top and bottom of the guide rail 5.4 are both provided with protrusions 5.5, and the guide groove is provided with a groove adapted to the protrusion 5.5.

[0043] The outer surface of the limit plate 5.1 has an arc of 15° to 35°. The outer surface of the limit plate 5.1 with a certain arc can provide a smoother sliding path, thereby reducing the friction and resistance between the guide rail 5.4 and the guide groove, so that the anti-collision device can respond and adjust its position more quickly when it is hit.

[0044] The limiting mechanism 5 and the limiting column 6 are both made of stainless steel, and the buffer plate 4.1 is made of glass fiber reinforced plastic or aluminum alloy. In one embodiment, the buffer plate 4.1 is preferably made of glass fiber reinforced plastic.

[0045] The spacing between the limit plates on both sides of the bridge column 1 is 50 to 80 cm. The spacing between each two adjacent buffer plates 4.1 is 10 to 20 cm. The base is located at the bottom of the bridge column 1, and the protective pad 3 is fixed on the four sides and four corners of the base 2. In one embodiment, the spacing between the limit plates on both sides of the bridge column 1 is preferably 60 cm. The spacing between each two adjacent buffer plates 4.1 is preferably 15 cm.

[0046] The retracted rod 4.2.2 is completely extended out of the sleeve 4.2.1, the outermost wall of the buffer mechanism 4 is located outside the outermost wall of the base 2, the retracted rod 4.2.2 is completely retracted into the sleeve 4.2.1, and the outermost wall of the buffer mechanism 4 and the outermost wall of the base 2 are on the same horizontal plane.

[0047] In one embodiment, the buffer plate 4.1, the buffer rod 4.2, and the limit plate 5.1 are sequentially installed at the bridge column 1, and the retracted rod 4.2.2 is completely extended from the sleeve 4.2.1, so that the outermost side of the buffer plate 4.1 is located at the outermost side of the base 2, thereby forming an additional protective layer for the bridge column. When a ship collides with the bridge column 1 due to an emergency, the hull of the ship will first hit the buffer plate 4.1 to prevent the ship from directly impacting the bridge column, and under the impact of the impact force, the spring 4.2.3 will be deformed, and the spring 4.2.3 will convert part of the impact force into the compression potential energy of the spring 4.2.3, thereby further reducing the direct impact of the ship on the bridge column 1.

[0048] When facing a large impact force, the limit plate 5.1 will move inward following the buffer plate 4.1. However, since the guide rail 5.4 is restricted by the guide groove at the limit column 6, the limit plate 5.1 will deform to a certain extent during the movement, thereby further converting and reducing the impact force, thereby further protecting the bridge column 1.

[0049] When the utility model is used, the limit column 6 is installed at the four corners between the bridge column 1 and the base 2, the buffer plate 4.1 is installed on both sides of the bridge column 1 through the buffer rod 4.2, and then the guide rail 5.4 of the limit plate 5.1 is moved and installed along the guide groove on the limit column 6 until the tooth 5.2 at the end of the limit plate 5.1 is inserted into the groove of the buffer plate 4.1, and then fixed by the fixing pin 4.3.

[0050] When hit, the impact force will first act on the buffer plate 4.1, and the retracted rod 4.2.2 will retract into the sleeve 4.2.1 as the buffer plate 4.1 moves, so that the spring 4.2.3 in the sleeve 4.2.1 will play a role in buffering and shock absorption, converting part of the impact force into compression potential energy of the spring, thereby reducing the direct impact on the bridge column and protecting the bridge structure. At the same time, the limit plate 5.1 will also move with the movement of the buffer plate 4.1, and during the movement, the limit plate 5.1 will undergo a certain deformation under the cooperation between the guide rail 5.4 and the guide groove, thereby further reducing the impact of the impact force on the bridge column 1.

[0051] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
