Description

Technical Field

[0001] This utility model belongs to the technical field of construction isolation devices, and in particular relates to a vehicle isolation device for highway construction. Background Technology

[0002] In highway construction, vehicle isolation devices are key facilities for ensuring the safety of the construction area, guiding traffic flow, and preventing vehicles from accidentally entering dangerous areas.

[0003] Common vehicle isolation devices include water-filled barriers, crash barriers, steel barriers, and movable guardrails. These are placed sequentially to create a closed-off area, isolating the construction zone from vehicles and directing traffic flow. However, these common isolation devices use an integrated design with a fixed structure and poor variability, especially at corners and transition points. Adjustments require disassembly and reassembly, and adjacent isolation devices also need to be repositioned. Utility Model Content

[0004] The technical problem this invention aims to solve is to improve the ease of use of the adjustable enclosure for construction areas by adopting a modular structure.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a vehicle isolation device for highway construction, including a base, a vertical plate, an adhesive plate, a screw, and a support limiting mechanism. The vertical plate is fixedly connected to one side of the upper part of the base. The adhesive plate is hinged to both sides of the vertical plate and is symmetrically distributed on the left and right sides with the vertical plate as the center. One end of the screw is fixedly connected to the side wall of the vertical plate and extends parallel to the base to one side. The other end of the screw is fixedly connected to a baffle. The support limiting mechanism is movably connected to the screw and can be adjusted along the axial direction of the screw for symmetrical adjustment of the opening and closing angle of the adhesive plate.

[0006] Furthermore, the support limiting mechanism includes a limiting plate, a supporting spring, and a connecting assembly. The limiting plate is slidably disposed on the outer wall of the screw near the baffle end. The connecting assembly is slidably connected to the outer wall of the screw near the upright plate end. The supporting spring is wound around the outer wall of the screw and located between the limiting plate and the supporting assembly to increase the stability between the limiting plate and the connecting assembly. The limiting plate has limiting grooves on the side wall away from the baffle, which are symmetrically distributed. The symmetrical limiting grooves are equal in width to the base and are used to limit the adhesive plate.

[0007] Furthermore, the support limiting mechanism also includes a limiting nut one and a limiting nut two. The limiting nut one is threaded to the outer wall of the screw and is located between the baffle and the limiting plate. The limiting nut two is threaded to the outer wall of the screw and is located between the connecting assembly and the upright plate. The positions of the limiting plate and the connecting assembly are adjusted by the limiting nut one and the limiting nut two.

[0008] Furthermore, the connecting assembly includes a connecting plate, a connecting block, and a magnetic suction plate. The connecting plate is slidably disposed on the outer wall of the screw, the connecting block is rotatably disposed at both ends of the connecting plate and is symmetrically distributed on the left and right sides with the connecting plate as the center, and the magnetic suction plate is fixedly connected to the side wall of the connecting plate for magnetic positioning and connecting the adhesive plate.

[0009] Furthermore, the bottom wall of the base has leakage holes arranged at even intervals, and a support block is fixedly connected to the bottom corner of the base.

[0010] Furthermore, a lifting hole is provided at the upper end of the upright plate.

[0011] After adopting the above structure, the beneficial effects of this utility model are as follows: For the adjustable enclosure of the construction area, the device improves the stability of placement by installing sand and gravel counterweights inside the base, uses the support and limiting mechanism to push the symmetrical adhesive plates to unfold, and realizes the corner adjustment and straight-face enclosure of the enclosure area by the opening angle of the symmetrical adhesive plates to achieve isolation, and attaches reflective markings to the outer surface of the adhesive plates to indicate vehicle traffic.

[0012] The device is easy to fold and store. After the connecting plate is rotated vertically, it is stored between the symmetrical adhesive plates. The symmetrical adhesive plates are fastened together. The position of the limiting plate is adjusted, and the symmetrical limiting grooves on its side wall limit the fastened adhesive plates, thus achieving the positioning and storage of the adhesive plates.

Detailed Implementation

[0020] like Figure 1-5 As shown, a vehicle isolation device for highway construction includes a base 1, a vertical plate 2, adhesive plates 3, a screw 4, and a support and limiting mechanism 5. The vertical plate 2 is fixedly connected to one side of the upper part of the base 1. The adhesive plates 3 are hinged to both sides of the vertical plate 2 and are symmetrically distributed around the vertical plate 2. One end of the screw 4 is fixedly connected to the side wall of the vertical plate 2 and extends parallel to the base 1 towards one side. The other end of the screw 4 is fixedly connected to a baffle 6. The support and limiting mechanism 5 is movably connected to the screw 4 and can be adjusted along the axial direction of the screw 4 for adjusting the opening and closing angle of the symmetrical adhesive plates 3. The bottom wall of the base 1 has leakage holes 16, which are evenly spaced. Support blocks 17 are fixedly connected to the bottom corners of the base 1. The upper end of the upright plate 2 has a lifting hole 18. The device improves the stability of the device by placing sand and gravel counterweights inside the base 1. At the same time, the leakage holes 16 at the bottom of the base 1 are used for rainwater leakage. The support blocks 17 raise the height of the base 1. The operator can drag the device through the lifting hole 18. In the initial state, the symmetrical adhesive plates 3 are locked together by the support limiting mechanism 5. The support limiting mechanism 5 is adjusted along the axial direction of the screw 4 to separate the symmetrical adhesive plates 3 from it.

[0021] like Figure 2-4As shown, to achieve the adjustment of the opening and closing angle of the symmetrical adhesive plate 3, the support limiting mechanism 5 includes a limiting plate 7, a support spring 8, and a connecting assembly 9. The limiting plate 7 is slidably disposed on the outer wall of the screw 4 near the baffle 6. The connecting assembly 9 is slidably connected to the outer wall of the screw 4 near the vertical plate 2. The support spring 8 is wound around the outer wall of the screw 4 and is located between the limiting plate 7 and the support assembly to increase the stability between the limiting plate 7 and the connecting assembly 9. The side wall of the limiting plate 7 away from the baffle 6 has a limiting groove 10, which is symmetrically distributed. The symmetrical limiting groove 10 is equal in width to the base 1 and is used to limit the adhesive plate 3. The support limiting mechanism 5 also includes a limiting nut 11 and a limiting nut 12. The limiting nut 11 is threadedly connected to the screw. The outer wall of the screw 4 is located between the baffle 6 and the limiting plate 7. The limiting nut 12 is threaded to the outer wall of the screw 4 and is located between the connecting assembly 9 and the upright plate 2. The position of the limiting plate 7 and the connecting assembly 9 is adjusted by the limiting nut 11 and the limiting nut 12. In the initial state, the limiting plate 7 and the limiting nut 11 are close to one end of the baffle 6 and the symmetrical adhesive plate 3 is limited by the limiting groove 10. The limiting nut 11 is rotated counterclockwise to make it closer to one end of the baffle 6. At the same time, the limiting plate 7 is separated from the symmetrical adhesive plate 3. The limiting nut 11 is rotated clockwise again to push the limiting plate 7 to move towards the connecting assembly 9. The elastic force of the supporting spring 8 is used to make the connecting assembly 9 close to the limiting nut 12 and close to the upright plate 2.

[0022] Rotate the limiting nut 12 clockwise, and under the elastic force of the support spring 8, the connecting component 9 moves toward the side of the upright plate 2. At the same time, the initial position of the limiting nut 12 moves away from the upright plate 2. Rotate the connecting component 9 90 degrees to make it horizontal, and support the inner wall of the two adhesive plates 3 through the connecting component 9.

[0023] To achieve symmetrical angle adjustment and fixation of the adhesive plate 3, the connecting assembly 9 includes a connecting plate 13, a connecting block 14, and a magnetic suction plate 15. The connecting plate 13 is slidably disposed on the outer wall of the screw 4, and the connecting block 14 is rotatably disposed at both ends of the connecting plate 13 and is symmetrically distributed on the left and right sides with the connecting plate 13 as the center. The magnetic suction plate 15 is fixedly connected to the side wall of the connecting plate 13 for magnetic positioning and connection of the adhesive plate 3. The connecting plate 13 is horizontally placed, and the rotating magnetic suction plate 15 is used to adhere to the inner wall of the adhesive plate 3. When the front and rear positions of the connecting plate 13 are stable, the symmetrical opening angle of the adhesive plate 3 is fixed.

[0024] In actual use, the device improves the stability of the device by installing sand and gravel counterweights in the base 1. The bottom of the base 1 has a seepage hole 16 for rainwater seepage. The support block 17 raises the height of the base 1. The operator can drag the device through the lifting hole 18. In the initial state, the symmetrical adhesive plates 3 are interlocked.

[0025] When in use, rotate the limiting nut 11 counterclockwise to bring it closer to one end of the baffle 6, while the limiting groove 10 separates from the symmetrical adhesive plate 3.

[0026] Rotate the limit nut 11 clockwise again to push the limit plate 7 toward the connecting component 9. Using the elastic force of the support spring 8, the connecting component 9 is made to fit against the limit nut 12 and move closer to the upright plate 2. Adjust the position of the connecting component 9 to achieve the axial movement of the connecting component 9 along the screw 4.

[0027] Rotate the connecting plate 13 by 90 degrees to make it horizontal. Use the rotating magnetic plate 15 to adhere to the inner wall of the adhesive plate 3. After the front and rear positions of the connecting plate 13 are fixed, the opening angle of the symmetrical adhesive plate 3 is fixed. According to the position of the connecting plate 13 of the limit nut 12, the opening angle of the symmetrical adhesive plate 3 can be adjusted.
