Description

Technical Field

[0001] This invention belongs to the technical field of guardrail equipment, specifically a modular bridge crash barrier and its implementation method. Background Technology

[0002] Bridge railings are a type of traffic safety facility installed on the outer side of the road shoulder, and they are particularly important in ensuring vehicle safety.

[0003] However, among existing technologies, concrete crash barriers are currently the most widely used, mostly constructed by casting in place. However, this method has drawbacks such as complicated construction procedures, long curing time, and low work efficiency. At the same time, the existing spliced ​​crash barriers have a fixed structure, which means that only a portion of the barrier can function when a collision occurs, leaving the non-collision areas in a restricted state. This can lead to serious damage to the barrier in the collision area, resulting in a reduction in the protective barrier effect. It also causes a waste of resources, making the actual performance of existing crash barrier equipment unsatisfactory. Summary of the Invention

[0004] The purpose of this invention is to provide a modular bridge crash barrier and its implementation method that can improve installation efficiency and provide higher protection in the event of a collision.

[0005] The technical solution adopted in this invention is as follows: a prefabricated bridge crash barrier, comprising: a support mechanism for providing a stable support foundation; A limiting mechanism, used to provide a connection base, is provided in three sets, all three sets of the limiting mechanism being mounted on the support mechanism; and The protective mechanism is used to provide a barrier and protection base. The protective mechanism is provided in three groups, and each group of the protective mechanism is respectively set on the corresponding limiting mechanism.

[0006] The support mechanism includes a base and a support seat. The top of the base has multiple connection holes, and the support seat is fixedly connected to the top of the base.

[0007] Each of the limiting mechanisms includes a protective sleeve, a limiting cover, a first side plate, a second side plate, and a limiting component. The protective sleeve is fixedly connected to the outer surface of one side of the support base, and a connecting shaft is fixedly connected to the outer surface of the protective sleeve. The limiting cover is slidably sleeved on the outer surface of the connecting shaft. The first side plate is fixedly connected to the outer surface of one side of the protective sleeve, and the second side plate is fixedly connected to the outer surface of the other side of the protective sleeve. The limiting component is disposed on the protective sleeve.

[0008] Each of the outer surfaces of the casing has two first threaded holes, and each of the outer surfaces of the limiting cover has two second threaded holes. Each second threaded hole and the corresponding first threaded hole are threadedly connected with a limiting bolt.

[0009] Each set of limiting components includes two retaining rings and two abutting rings. The two retaining rings are slidably disposed inside the protective sleeve. Each retaining ring has a retaining groove on one side of its outer surface. The two abutting rings are slidably disposed inside the protective sleeve. Each abutting ring has a sleeve connected to one side of its outer surface. Each sleeve has a limiting spring fitted on its outer surface.

[0010] Each set of protective mechanisms includes a protective tube, an extension steel rope, and a linkage component. The protective tube is slidably disposed inside the corresponding retaining ring, the extension steel rope slidably passes through the protective tube, and the linkage component is disposed on the extension steel rope.

[0011] Each of the protective tubes has two extension rings threaded to its outer surface. The inner wall of each slot and the outer surface of the corresponding extension ring are in contact. Each of the protective tubes has two sets of support blocks that slide inside. Each set of support blocks has two blocks. A support strip is fixedly connected between the outer surfaces of the two support blocks in each set.

[0012] Each set of linkage components includes two linkage blocks, two sets of locking rods, and two sets of locking cylinders. Each set of locking rods has two rods, and each set of two locking rods is fixedly connected to the ground inside the corresponding linkage block. Each set of locking cylinders has two cylinders, and each cylinder is slidably sleeved on the outer surface of the corresponding locking rod. The two cylinders in each set are internally connected.

[0013] Each of the extended steel ropes has a stop block fixedly connected to both ends. Two connecting bolts are threaded between the outer surfaces of the two linkage blocks in each group. The outer surface of each stop ring is in contact with the outer surface of one side of the corresponding two linkage blocks. One end of each extended steel rope slides through the interior of the corresponding two clamps.

[0014] A method for implementing a prefabricated bridge crash barrier includes the following steps: S1. Quick Assembly: The base can be securely installed in the designated position using existing bolts through the connecting holes. Then, the protective tube can be quickly installed between adjacent protective tubes through the extension ring and the retaining ring. At the same time, the two ends of the extension steel rope can be clamped between the corresponding two sets of connecting blocks through the retaining tube and the abutment. Then, multiple extension steel ropes can be quickly connected through the connecting blocks. Under the compression of one end of the limit spring, the corresponding abutment can be tightly attached to the corresponding connecting block. Under the compression of the other end of the limit spring, the extension ring can be tightly attached to the inside of the slot. Thus, the protective tube can be stably installed between two adjacent protective tubes, and then, together with the support base, form a barrier protection effect. S2. Barrier Protection: When the protective tube is subjected to impact and compression, under small impact forces, the support blocks and support bars prevent severe deformation of the protective tube. Under larger impact forces, the base, support seat, protective cylinder, first side plate, second side plate, retaining ring, and extension ring provide initial barrier protection against the impacting object. Simultaneously, during severe deformation of the protective tube due to impact, the extension steel rope will be simultaneously compressed, causing both ends of the extension steel rope to contract towards the impact point. At this time, both ends of the extension steel rope will be... The abutment block drives the corresponding clamping cylinder to move synchronously, which in turn causes the clamping cylinder to work with the clamping rod to drive the corresponding linkage block to move synchronously. This allows the linkage block to work with the clamping rod and clamping cylinder to drive the adjacent extension steel rope to move. The adjacent extension steel rope can synchronously pull the corresponding linkage block to squeeze the abutment ring on one side of the movement direction. The abutment ring can squeeze the limiting spring to reduce the excessive impact of the extension steel rope on the corresponding protective cylinder, the first side plate and the second side plate. This allows the extension steel rope in the collision area to work in conjunction with the non-collision area protection mechanism, the limiting mechanism and the support mechanism to synchronously provide barrier protection against collision.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: (1) In this invention, when in use, the base can be securely set in the designated use position by existing bolts through the connecting hole, and then the protective tube can be quickly installed between adjacent protective tubes through the extension ring and the retaining ring. At the same time, the two ends of the extension steel rope can be clamped between the corresponding two sets of connecting blocks through the retaining tube and the abutment. Then, multiple extension steel ropes can be quickly connected through the connecting block. At the same time, under the compression of one end of the limiting spring, the corresponding abutment can be tightly attached to the corresponding connecting block. Under the compression of the other end of the limiting spring, the extension ring can be tightly attached to the inside of the slot. Thus, the protective tube can be stably set between two adjacent protective tubes, and then form an efficient barrier protection effect with the support base. At the same time, the equipment can be conveniently spliced ​​and installed.

[0016] (2) In this invention, when the protective tube is subjected to collision and compression, when the collision force is small, the protective tube can avoid severe deformation under the support of the support block and support strip. When the collision force is large, the protective tube can initially block and protect against the collision object under the support of the base, support seat, protective tube, first side plate, second side plate, clamping ring and extension ring. At the same time, during the process of severe deformation of the protective tube due to collision, the extension steel rope will be simultaneously subjected to collision and compression, thereby causing the two ends of the corresponding extension steel rope to contract towards the collision point. At this time, the two ends of the extension steel rope will cooperate with the abutment block to drive the corresponding clamping ring synchronously. The movement causes the clamping cylinder and clamping rod to move the corresponding linkage block synchronously. This allows the linkage block to move the adjacent extension steel rope in conjunction with the clamping rod and clamping cylinder. The adjacent extension steel rope can then synchronously pull the corresponding linkage block to squeeze the abutment ring on one side of the movement direction. The abutment ring can squeeze the limiting spring to reduce the excessive impact of the extension steel rope on the corresponding protective cylinder, first side plate, and second side plate. This allows the extension steel rope in the collision area to work in conjunction with the non-collision area protection mechanism, limiting mechanism, and support mechanism to provide synchronous protection against collisions, avoiding waste of resources and improving the actual protection effect.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] For examples, please refer to [link / reference]. Figures 1-4 A modular bridge crash barrier consists of a support mechanism 1, a limiting mechanism 2, and a protective mechanism 3.

[0021] The details are as follows: Please see Figure 5 Support mechanism 1 is used to provide a stable support base, including base 101 and support seat 102. The top of base 101 has multiple connection holes. Support seat 102 is fixedly connected to the top of base 101. Through the connection holes, base 101 can be firmly set in the designated use position by existing bolts, thereby enabling support seat 102 to stably install limit mechanism 2 and protection mechanism 3. Please see Figure 6 and Figure 7Each set of limiting mechanisms 2 provides a connection base. There are three sets of limiting mechanisms 2, all mounted on the support mechanism 1. Each set includes a protective sleeve 201, a limiting cover 208, a first side plate 202, a second side plate 203, and limiting components. The protective sleeve 201 is fixedly connected to the outer surface of one side of the support base 102. A connecting shaft is fixedly connected to the outer surface of the protective sleeve 201. The limiting cover 208 is slidably sleeved on the outer surface of the connecting shaft. The first side plate 202 is fixedly connected to the outer surface of one side of the protective sleeve 201, and the second side plate 203 is fixedly connected to... Attached to the outer surface of the other side of the casing 201, the limiting components are disposed on the casing 201. Each casing 201 has two first threaded holes on its outer surface, and each limiting cover 208 has two second threaded holes on its outer surface. A limiting bolt is threaded between the interior of each second threaded hole and the corresponding first threaded hole. Each set of limiting components includes two retaining rings 204 and two abutment rings 205. The two retaining rings 204 are slidably disposed inside the casing 201. Each retaining ring 204 has a retaining groove on one side of its outer surface. The two abutment rings 204... The 05 are all slidably disposed inside the protective sleeve 201. Each abutment ring 205 has a sleeve 206 connected to one side of its outer surface. Each sleeve 206 has a limiting spring 207 fitted on its outer surface. Under the compression of one end of the limiting spring 207, the corresponding abutment ring 205 can be tightly attached to the corresponding connecting block. Under the compression of the other end of the limiting spring 207, the extension ring 302 can be tightly attached to the inside of the slot. Thus, the protective tube 301 can be stably disposed between two adjacent protective sleeves 201, and then, together with the support base 102, form an efficient barrier. The adjacent extension steel ropes 305 can synchronously pull the corresponding linkage block 307 to squeeze the abutment ring 205 on one side of the moving direction, so that the abutment ring 205 can squeeze the limiting spring 207 to reduce the excessive impact of the extension steel ropes 305 on the corresponding protective cylinder 201, the first side plate 202 and the second side plate 203. In this way, the extension steel ropes 305 in the collision area can work together with the non-collision area protection mechanism 3, the limiting mechanism 2 and the support mechanism 1 to provide isolation protection for the collision, avoid the waste of resources, and improve the actual protection effect. Please see Figures 8-11Each set of protective mechanisms 3 provides a barrier protection base. There are three sets of protective mechanisms 3, each set mounted on a corresponding limiting mechanism 2. Each set includes a protective tube 301, an extension steel rope 305, and a connecting component. The protective tube 301 is slidably disposed inside the corresponding retaining ring 204. The extension steel rope 305 slidably passes through the protective tube 301. The connecting component is disposed on the extension steel rope 305. Two extension rings 302 are threadedly connected to the outer surface of each protective tube 301. The inner wall of each retaining groove and the outer surface of the corresponding extension ring 302 are in contact. Two sets of support blocks 303 are slidably involved inside each protective tube 301. Each set of support blocks 303 has two blocks, and each set has two supports. Support bars 304 are fixedly connected between the outer surfaces of the support blocks 303. Each set of linkage components includes two linkage blocks 307, two sets of locking rods 309, and two sets of locking cylinders 310. There are two locking rods 309 in each set, and each set of two locking rods 309 is fixedly connected to the ground inside the corresponding linkage block 307. There are two locking cylinders 310 in each set, and each locking cylinder 310 is slidably sleeved on the outer surface of the corresponding locking rod 309. The two locking cylinders 310 in each set are internally connected. Each extension steel rope 305 has a stop block 306 fixedly connected to both ends. There are two connecting bolts 308 threaded between the outer surfaces of the two linkage blocks 307 in each set. The outer surface of each stop ring 205 and one side of the corresponding two linkage blocks 307 are connected. The outer surfaces are all fitted together. One end of each extension steel rope 305 slides through the interior of two corresponding clamping cylinders 310. The extension ring 302 and clamping ring 204 allow for quick installation of the protective tube 301 between adjacent protective cylinders 201. Simultaneously, the clamping cylinders 310 and abutment blocks 306 allow for clamping both ends of the extension steel rope 305 between two sets of connecting blocks. The connecting blocks then allow for rapid linkage of multiple extension steel ropes 305. When the protective tube 301 is subjected to impact and compression, under small impact forces, the support blocks 303 and support bars 304 prevent severe deformation of the protective tube 301. Under larger impact forces, the base 101 and support seat 10... 2. With the support of the protective tube 201, the first side plate 202, the second side plate 203, the retaining ring 204, and the extension ring 302, the protective tube 301 can initially block and protect against collisions. At the same time, when the protective tube 301 is severely deformed by a collision, the extension steel rope 305 will be simultaneously squeezed by the collision, causing the two ends of the corresponding extension steel rope 305 to retract towards the collision point. At this time, the two ends of the extension steel rope 305 will cooperate with the abutment block 306 to drive the corresponding retaining cylinder 310 to move synchronously. Then, the retaining cylinder 310, in conjunction with the retaining rod 309, will drive the corresponding linkage block 307 to move synchronously. In turn, the linkage block 307 can cooperate with the retaining rod 309 and the retaining cylinder 310 to drive the adjacent extension steel rope 305 to move.

[0022] The following provides a detailed description of an implementation method for a prefabricated bridge crash barrier provided by an embodiment of the present invention. The method of use includes the following steps: Step 1, Rapid Assembly: The base 101 can be securely installed in the designated position using existing bolts through the connecting holes. Then, the protective tube 301 can be quickly installed between adjacent protective tubes 201 through the extension ring 302 and the retaining ring 204. At the same time, the two ends of the extension steel rope 305 can be clamped between the corresponding two sets of connecting blocks through the retaining tube 310 and the abutment block 306. Then, multiple extension steel ropes 305 can be quickly connected through the connecting blocks. Under the compression of one end of the limit spring 207, the corresponding abutment 205 can be tightly attached to the corresponding connecting block. Under the compression of the other end of the limit spring 207, the extension ring 302 can be tightly attached to the inside of the slot. Thus, the protective tube 301 can be stably set between two adjacent protective tubes 201, and then, together with the support base 102, it forms an efficient barrier protection effect, while making the equipment easy to assemble and install. Step Two, Barrier Protection: When the protective tube 301 is subjected to impact and compression, if the impact force is small, the support block 303 and support bar 304 can prevent the protective tube 301 from undergoing severe deformation. If the impact force is large, the base 101, support seat 102, protective tube 201, first side plate 202, second side plate 203, retaining ring 204, and extension ring 302 can provide initial barrier protection against the impacting object. Simultaneously, during the severe deformation of the protective tube 301 due to impact, the extension steel rope 305 will be simultaneously subjected to impact and compression, causing both ends of the extension steel rope 305 to retract towards the impact point. At this time, the two ends of the extension steel rope 305 will cooperate with the abutment block 306 to drive the corresponding retaining ring 310 to retract towards the impact point. The movement of the cylinder 310, in conjunction with the lever 309, causes the corresponding linkage block 307 to move synchronously. This allows the linkage block 307 to move in conjunction with the lever 309 and the cylinder 310, thereby moving the adjacent extension steel rope 305. The adjacent extension steel rope 305 can then synchronously pull the corresponding linkage block 307 to press the abutment ring 205 on one side of the movement direction. The abutment ring 205 can then press the limiting spring 207 to reduce the excessive impact of the extension steel rope 305 on the corresponding protective cylinder 201, the first side plate 202, and the second side plate 203. This allows the extension steel rope 305 in the impact area to work in conjunction with the non-impact area protection mechanism 3, the limiting mechanism 2, and the support mechanism 1 to provide synchronous protection against collisions, avoiding waste of resources and improving the actual protection effect.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

Barrier Protection: When the protective tube (301) is subjected to collision and compression, when the collision force is small, the protective tube (301) can avoid severe deformation under the support of the support block (303) and support bar (304).
