Description

Technical Field

[0001] This invention belongs to the field of guardrail technology, specifically relating to a mobile crash barrier. Background Technology

[0002] The term "guardrail" here refers to industrial "protective railings." Guardrails are primarily used in residential areas, highways, commercial areas, and public places to protect personal safety and equipment. Guardrails are ubiquitous in our lives, and the price per meter varies depending on the height. Crash barriers, on the other hand, are steel railings mainly used in factories, warehouses, and roads for protecting equipment and facilities. They are typical cold-formed steel products, offering advantages such as good impact resistance, low cost, long lifespan, and higher safety. Road crash barriers are widely used on municipal roads, not only installed on the sides of the road to prevent vehicles from crashing off the road, but also on the road surface to separate forward and reverse traffic, or to separate motor vehicle and non-motor vehicle lanes. However, existing crash barriers have the following technical problems in use:

[0003] (1) At present, crash barriers are generally used on highways or highway bridges. When a vehicle is involved in an accident, it will not break through the crash barrier and fall to the road surface or bridge surface below, causing greater losses and injuries. For example, the guardrail is made of reinforced concrete. However, for this kind of rigidly connected guardrail, although it can prevent the vehicle from running off the road, the vehicle body is also easily seriously damaged, which may seriously endanger personal safety. In addition, the crash barrier will also be damaged by strong impact.

[0004] (2) In most cases, the shape of guardrails should be adapted to the shape of the road, but the current guardrails are usually straight and difficult to adjust;

[0005] (3) The height of a conventional crash barrier is fixed. When it is installed on roads where large vehicles frequently travel, the height of a conventional crash barrier is relatively low, which reduces its safety performance and practicality. Summary of the Invention

[0006] The purpose of this invention is to provide a mobile crash barrier that solves the technical problem of how to make the crash barrier both protect vehicles and protect itself. It is also suitable for roads with large vehicles, improving safety and practicality.

[0007] A movable crash barrier includes multiple barrier units connected in sequence, with adjacent barrier units connected by a spring assembly.

[0008] The guardrail unit includes two parallel chain structures set on the ground, multiple connecting posts connected to the two chain structures, positioning blocks set on the connecting posts, a linkage assembly connected to two adjacent positioning blocks, and a positioning adjustment assembly movably connected to the linkage assembly. Power components are respectively provided at both ends of the connecting posts.

[0009] The chain structure includes multiple chain link modules that are hinged together in sequence. Each chain link module includes a chain link one and a chain link two that is connected to the chain link one by a positioning pin, with the positioning pin placed perpendicular to the ground.

[0010] The two ends of the connecting post are respectively vertically fixed to the inner side of the first link or the second link. The bottom end of the positioning block is provided with a slot. The inner side of the slot is coated with glue and is fixed to the connecting post by the glue.

[0011] The linkage assembly includes a horizontally placed linkage and a vertically threaded column that passes through the linkage. The two ends of the linkage are respectively horizontally rotatably connected to the tops of two adjacent positioning blocks, and the bottom end of the column contacts the ground or extends below the ground.

[0012] The positioning adjustment assembly includes a gear rotatably connected to the outside of the column, a gear belt meshing with both sides of the gear, and end gear one and end gear two respectively disposed at both ends of the gear belt. The gear belt passes horizontally through multiple positioning blocks, and the centers of end gear one and end gear two pass vertically through a drive shaft. The drive shaft is rotatably connected to the positioning blocks at the outer end of the guardrail unit.

[0013] The spring assembly includes an upper spring and a lower spring, with the two ends of the upper spring and the lower spring respectively hooked and fixed to the upper and lower ends of the drive shafts on two adjacent guardrail units.

[0014] The outer sides of the plurality of positioning blocks are covered with elastic bands by adhesive.

[0015] A stop block is coaxially fixed at the bottom of the drive shaft, and a rotating handle is fixed at its top.

[0016] The power assembly includes a threaded column that is vertically rotatably connected to the connecting column, a power shaft that extends vertically into the top of the threaded column, a retaining strip fixed to the outside of the power shaft, and a micro motor connected to the top of the power shaft. An AGV drive wheel is fixed to the bottom of the threaded column, and the AGV drive wheel is wirelessly connected to the controller.

[0017] In the industrial sector, the drive wheels used in Automated Guided Vehicles (AGVs) are typically omnidirectional wheels equipped with autonomous walking capabilities. These drive wheels help AGVs achieve autonomous movement and navigation, thereby improving the automation level and production efficiency of industrial equipment. This solution utilizes AGV drive wheels to facilitate autonomous movement and navigation.

[0018] The gear belt is made of steel wire rope core material.

[0019] For any technical details not described in detail in this solution, please refer to the conventional understanding and operation of those skilled in the art. Implementing this solution will not be elaborated further here.

[0020] This invention achieves the following significant effects:

[0021] (1) This solution includes spring components and guardrail units, which have the following technical advantages:

[0022] Firstly, it is easy to disassemble; simply remove the spring assembly from the guardrail unit to complete the transfer and transportation of the guardrail unit.

[0023] Secondly, when the guardrail unit is impacted, the spring assembly acts as a buffer, preventing excessive damage to the guardrail unit and the vehicle body.

[0024] (2) It is equipped with a chain structure, connecting columns and positioning blocks, which achieves the following technical effects:

[0025] Firstly, the flexible connection of the chain structure allows the car to bend quickly when it hits the guardrail, which helps protect both the guardrail and the vehicle body.

[0026] The bending characteristics of the two-chain structure make this guardrail suitable for protecting curved roads;

[0027] Third, the adhesive connection between the positioning block and the connecting column allows the solidified adhesive to buffer the impact and also provides a safety valve for collision prevention.

[0028] Fourth, an elastic band is glued to the outside of the positioning block, which helps to achieve a cushioning effect against impacts.

[0029] (3) A linkage assembly is provided. On the one hand, the linkage increases the connection strength between two adjacent positioning blocks to prevent the positioning blocks from falling apart after being hit. On the other hand, the bottom of the column is inserted into or in contact with the ground through the action of the column. Adjusting the height of the column makes the guardrail suitable for roads where large vehicles frequently appear.

[0030] (4) A positioning adjustment component is provided, which works in conjunction with the connecting rod assembly to achieve the following technical effects:

[0031] Firstly, the gears mesh on the inner side of the gear belt, which helps to limit the position of the column and increase its stability.

[0032] Secondly, the gear belt drives the column to rotate and move up and down, making it easy to position the column on the ground.

[0033] Third, the drive shaft can also be used with a spring assembly and connected to the upper and lower springs. Attached Figure Description

[0043] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0044] See Figures 1-8 A movable crash barrier includes multiple barrier units connected in sequence, with adjacent barrier units connected by a spring assembly.

[0045] The guardrail unit includes two parallel chain structures 1 set on the ground, multiple connecting posts 13 connected to the two chain structures 1, positioning blocks 8 set on the connecting posts 13, a linkage assembly connected to two adjacent positioning blocks 8, and a positioning adjustment assembly movably connected to the linkage assembly. Power components are respectively set at both ends of the connecting posts 13.

[0046] The chain structure 1 includes multiple chain link modules that are hinged together in sequence. Each chain link module includes a first chain link 11 and a second chain link 12 that is connected to the first chain link 11 by a positioning pin. The positioning pin is placed perpendicular to the ground.

[0047] Chain structure 1 is actually an existing structural component, but this solution adapts it to the field of guardrails, so that the guardrails can bend automatically after being impacted, which can achieve both self-protection and vehicle protection.

[0048] The two ends of the connecting post 13 are vertically fixed to the inner side of link 11 or link 12, respectively. The bottom end of the positioning block 8 is provided with a slot, the inner side of the slot is coated with glue, and is fixed to the connecting post 13 by the glue.

[0049] The linkage assembly includes a horizontally placed linkage 6 and a vertically threaded column 5 that passes through the linkage 6. The two ends of the linkage 6 are respectively horizontally rotatably connected to the tops of two adjacent positioning blocks 8, and the bottom end of the column 5 contacts the ground or extends below the ground.

[0050] It should be noted that a corresponding cylindrical structure can be installed on the road surface or roadside so that the post 5 can be inserted into the cylindrical structure to achieve the limiting function; when it is necessary to move the guardrail, the post 5 can be removed from the cylindrical structure.

[0051] The positioning adjustment assembly includes a gear 51 rotatably connected to the outside of the column 5, a gear belt 3 meshing with both sides of the gear 51, and end gear one and end gear two respectively set at both ends of the gear belt 3. The gear belt 3 passes horizontally through multiple positioning blocks 8, and the centers of end gear one and end gear two pass vertically through the drive shaft 41. The drive shaft 41 is rotatably connected to the positioning blocks 8 at the outer end of the guardrail unit.

[0052] In addition, the gear belt 3 and gear structure mentioned above can be replaced with a synchronous belt and synchronous pulley structure, which is hereby noted.

[0053] More preferably, an opening groove 81 is provided on the inner side of the positioning block 8, and the gear 51 is disposed in the opening groove 81.

[0054] The spring assembly includes an upper spring 7 and a lower spring 7. The two ends of the upper spring 7 and the lower spring 7 are respectively hooked to the upper and lower ends of the drive shaft 41 fixed on two adjacent guardrail units.

[0055] Multiple positioning blocks 8 have elastic bands 2 glued to their outer sides. The elastic bands 2 can be made of rubber or other materials.

[0056] A stop block 42 is coaxially fixed at the bottom of the drive shaft 41 (to prevent the lower spring from falling off), and a handle 4 is fixed at the top of the shaft. The handle 4 is used for manual rotation.

[0057] The power assembly includes a threaded post 93 vertically rotatably connected to the connecting post 13, a power shaft 91 extending vertically into the top of the threaded post 93, a retaining bar 92 fixed to the outside of the power shaft 91, and a micro motor 9 connected to the top of the power shaft 91. An AGV drive wheel is fixed to the bottom of the threaded post 93, and the AGV drive wheel is wirelessly connected to the controller. During operation, the micro motor 9 drives the power shaft 91 to rotate, which in turn drives the threaded post 93 to rotate. The retaining bar 92 moves vertically within the threaded post 93, thereby adjusting the direction of the AGV drive wheel. The AGV drive wheel can move up and down, allowing the chain structure 1 to contact or separate from the ground. For design simplification, the entire power assembly is not shown in the attached drawings.

[0058] In the industrial sector, the drive wheels used in Automated Guided Vehicles (AGVs) are typically omnidirectional wheels equipped with autonomous walking capabilities. These drive wheels help AGVs achieve autonomous movement and navigation, thereby improving the automation level and production efficiency of industrial equipment. This solution utilizes AGV drive wheels to facilitate autonomous movement and navigation.

[0059] The gear belt 3 is made of steel wire rope core material.

[0060] The specific working process of this invention is as follows:

[0061] When in use, the guardrail unit is impacted, and the spring assembly acts as a buffer to prevent excessive damage to the guardrail unit and the vehicle body.

[0062] This solution includes a spring assembly and a guardrail unit, which are easy to disassemble. Simply remove the spring assembly from the guardrail unit to complete the transfer and transportation of the guardrail unit.

[0063] The system is equipped with a chain structure 1, a connecting post 13, and a positioning block 8. The flexible connection of the chain structure 1 allows the car to bend quickly when it hits the guardrail, which helps protect the guardrail and the vehicle body.

[0064] The bending characteristics of the chain structure 1 make this guardrail suitable for protecting curved roads;

[0065] The adhesive connection between the positioning block 8 and the connecting column 13 allows the solidified adhesive of the positioning block 8 to buffer the impact and also provides a safety valve for collision prevention.

[0066] An elastic band 2 is glued to the outside of the positioning block 8, which helps to achieve a cushioning effect against impacts.

[0067] The system is equipped with a linkage assembly. On the one hand, the linkage 6 increases the connection strength between two adjacent positioning blocks 8, preventing the positioning blocks 8 from falling apart after being hit. On the other hand, the column 5 allows the bottom end of the column 5 to be inserted into or in contact with the ground. Adjusting the height of the column 5 makes the guardrail suitable for roads where large vehicles frequently pass.

[0068] A positioning adjustment component is provided, which works in conjunction with the connecting rod assembly. The gear 51 meshes with the inner side of the gear belt 3, which helps to limit the position of the column 5 and increase its stability.

[0069] Driven by the gear belt 3, the column 5 rotates and moves up and down, making it easy to position the column 5 on the ground; the drive shaft 41 can also cooperate with the spring assembly and connect with the upper spring 7 and the lower spring 7.

[0070] The technical features of this invention not described can be implemented by or using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this invention, and this invention is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this invention should also be within the protection scope of this invention.
