Description

Technical Field

[0001] This utility model belongs to the field of highway technology, and in particular relates to a highway crash barrier base assembly and disassembly component. Background Technology

[0002] Currently, highway crash barrier bases are installed by welding or multiple bolts to the guardrails. However, when disassembling, repairing, or replacing the guardrails later, the welded points or numerous bolts are difficult to remove, resulting in a large workload. Furthermore, under long-term vehicle impacts, vibrations, and the influence of the natural environment, loosening and displacement are likely to occur. Therefore, there is a need for a highway crash barrier base disassembly and assembly component that uses a pre-locking followed by compression locking method. This improves the installation strength of the guardrail and increases the speed of disassembly and assembly. On the other hand, the double-locking installation method effectively reduces the risk of subsequent guardrail detachment. Utility Model Content

Detailed Implementation

[0021] In the following description, embodiments of the highway crash barrier base assembly of this utility model will be described with reference to the accompanying drawings.

[0022] Figure 1-4This invention illustrates a highway crash barrier base assembly and disassembly system according to an embodiment of the present invention. The assembly includes a rectangular sleeve 2 welded to the top of a base 1. A guardrail 3 is positioned above the base 1, and a sealing gasket 7 is fixedly connected to the bottom of the guardrail 3. A rectangular groove matching the sealing gasket 7 is formed on the top of the rectangular sleeve 2. The sealing gasket 7 and the rectangular groove work together to seal the contact area between the rectangular sleeve 2 and the guardrail 3, preventing rainwater from entering the inner cavity of the rectangular sleeve 2 and protecting the internal components of the rectangular sleeve 2 and the connector 4. The front and rear sides of the rectangular sleeve 2 are both provided with hexagonal sleeves 65. The adjustable hole 8 is fitted with a sealing plug 9. A connecting joint 4 is fixedly connected to the bottom of the guardrail 3. The connecting joint 4 is inserted into the inner cavity of the rectangular sleeve 2. Pre-locking components 5 are provided on both sides of the inner cavity of the connecting joint 4. Each pre-locking component 5 includes a rectangular sliding groove 51 formed on both sides of the inner cavity of the connecting joint 4. A sliding plate 52 is slidably connected to the inner cavity of the rectangular sliding groove 51. Limiting clips 53 are fixedly connected to the top and bottom of the opposite sides of the two sliding plates 52. Two limiting slots 54 are formed on both sides of the rectangular sleeve 2. The limiting clips 53 are inserted into the inner cavity of the limiting slots 54. The two sliding plates 52 are opposite sides of each other. Springs 55 are welded to the top and bottom of the side. The end of the spring 55 away from the sliding plate 52 is welded to the inner wall of the rectangular slide groove 51. A locking assembly 6 is provided in the inner cavity of the connector 4. The locking assembly 6 includes a pressure block 61 fixedly connected to the side of the sliding plate 52 away from the limiting clip 53. An extrusion block 62 is slidably connected to the front and rear sides of the inner cavity of the connector 4. The extrusion block 62 and the side opposite to the pressure block 61 are provided with a beveled surface. A bidirectional screw 63 is provided in the inner cavity of the connector 4. Both extrusion blocks 62 are threaded to the surface of the bidirectional screw 63. The sides opposite to the two pressure blocks 61 are open. A pre-reserved arc groove 64 adapted to the bidirectional lead screw 63 is provided. The bidirectional lead screw 63 is rotatably connected to the inner cavity of the connector 4. The front and rear ends of the bidirectional lead screw 63 extend to the outside of the connector 4 and are fixedly connected to a hexagonal sleeve 65. Through the setting of the locking assembly 6, the bidirectional lead screw 63 and the hexagonal sleeve 65 work together to push the two pressing blocks 62 in a threaded manner, so that the two pressing blocks 62 can move towards each other and compress the pressure block 61. This allows the limiting clip 53 to be stably engaged in the inner cavity of the limiting clip groove 54, improving the connection stability of the connector 4 and the shaped sleeve 2.

[0023] Working Principle: When using this utility model, the user fixes the base 1 to the designated position using external bolts. Then, the user holds the guardrail 3 and inserts the connector 4 into the inner cavity of the rectangular sleeve 2, so that the bottom of the limiting clip 53 contacts the top of the rectangular sleeve 2 first. Due to the blocking effect of the rectangular sleeve 2, the limiting clips 53 on both sides slide, causing the two sliding plates 52 to slide in the inner cavity of the rectangular groove 51, while compressing the spring 55. Until the bottom of the connector 4 contacts the bottom of the inner cavity of the rectangular sleeve 2, the sliding plates 52 slide in the opposite direction under the elastic force of the spring 55, and drive the limiting clips 53 to engage with the limiting clips. Inside the groove 54, the guardrail 3 and the connector 4 are limited. Then, the user inserts a hex wrench into the inner cavity of the hexagonal sleeve 65 and rotates the double-acting screw 63. During the rotation, the double-acting screw 63 pushes the two pressing blocks 62 through its surface threads, causing the two pressing blocks 62 to move towards each other and making the inclined surface of the pressing block 62 fit tightly against the inclined surface of the pressure block 61. At this time, the pressure block 61 is compressed and locked, thereby making the limiting clip 53 stably engaged in the inner cavity of the limiting clip groove 54. Finally, the user inserts the sealing plug 9 into the inner cavity of the adjusting hole 8 to seal the adjusting hole 8.

[0024] In summary, this highway crash barrier base assembly and disassembly module, through the cooperation of the rectangular sleeve 2 and the connector 4, enables the base 1 and the guardrail 3 to be connected. Subsequently, the connector 4 is pre-locked by the pre-locking component 5, and the connector 4 and the guardrail 3 are further locked by the cooperation of the locking component 6. This achieves the purpose of simple and quick installation and stable and reliable connection.
