Description

Technical Field

[0001] This utility model relates to the field of protective device technology, specifically a pollution prevention device for concrete guardrails used in highway pavement construction. Background Technology

[0002] Asphalt pavement construction is a common task in highway maintenance and reconstruction projects. Concrete guardrails, as crucial facilities for ensuring road traffic safety, have surface cleanliness that affects not only the road's aesthetics but also the visibility of reflective markings, thus impacting nighttime driving safety.

[0003] Based on the above, the inventors have discovered the following problems: In existing highway asphalt pavement construction, whether it's the paving, compaction, or transportation of asphalt mixtures, it's extremely easy to contaminate the concrete guardrails on both sides. Contaminated concrete guardrails not only severely affect the overall aesthetics of the road but also increase the difficulty and cost of subsequent cleaning. Asphalt has strong adhesion and chemical stability; once it dries and hardens, conventional washing and wiping methods are insufficient to completely remove it. Often, professional chemical cleaning agents or mechanical grinding are required, which not only consumes a large amount of manpower and resources but also risks corroding the guardrail surface with chemical cleaning agents, affecting the guardrail's service life.

[0004] Therefore, in view of this, we will study and improve the existing structure and its deficiencies, and provide a pollution prevention device for concrete guardrails in highway pavement construction, in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this utility model is to provide a pollution prevention device for concrete guardrails during highway pavement construction, in order to solve the problem mentioned in the background art that the concrete guardrails on both sides are easily polluted during the paving, compaction and transportation of asphalt mixtures in the existing highway asphalt pavement construction.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: A pollution prevention device for concrete guardrails used in highway pavement construction includes a guardrail body and a protective mechanism. The protective mechanism includes a main board, with a mounting frame fixedly installed at the bottom of the main board. Several rotating shafts are rotatably connected inside the mounting frame, and first rollers are fitted at both ends of each rotating shaft. The bottom ends of the first rollers are tactilely connected to the upper surface of the guardrail body. Baffles and counterweights are respectively hinged to both sides of the main board via several hinges. Several first movable seats are fixedly installed on both sides of the mounting frame. Several second movable seats are installed on the upper ends of the opposing surfaces of the baffles and counterweights. Tension springs are hinged inside the second movable seats via pins, and the other ends of the tension springs are hinged to the interior of the first movable seats via pins.

[0007] Furthermore, three sets of movable frames are fixedly installed on the inner side of the baffle, and a first fixed frame is provided between each set of movable frames.

[0008] The beneficial effect of adopting the above-mentioned further solution is that the three sets of movable frames on the inner side of the baffle provide a base for the installation and adjustment of the first fixed frame. The position of the first fixed frame can be adjusted according to the side shape of the guardrail body to ensure that the second roller contacts the outer side of the guardrail, improve the stability of the baffle when it moves with the device, and avoid shaking that could cause protective gaps.

[0009] Furthermore, each of the first fixing frames is rotatably connected to a second roller, which is in rolling connection with the outer side of the guardrail body.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the second roller in the first fixed frame is rolledly connected to the outer side of the guardrail body, which converts the sliding friction between the baffle and the guardrail body into rolling friction, reduces the moving resistance, makes the device move more smoothly along the guardrail, and at the same time limits the deviation of the baffle to ensure the stability of the protection range.

[0011] Furthermore, locking screws are installed at both ends of one side of the first fixed frame, and the upper and lower ends of the locking screws are slidably connected to the interior of the movable frame.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the two ends of the locking screw slide within the movable frame, which can flexibly adjust the extension length of the first fixed frame, thereby making the second roller abut against the outer side of the guardrail body, ensuring that the second roller fits against the outer side of the guardrail.

[0013] Furthermore, both the upper and lower ends of the locking screw are threaded with locking nuts, and the facing surfaces of each pair of locking nuts abut against the upper and lower ends of the movable frame, respectively.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the locking nut and the locking screw are threaded together, and after tightening, the first fixed frame can be firmly fixed in the set position of the moving frame, preventing the first fixed frame from loosening or shifting during the movement of the device, and ensuring the stability of the support and guiding function of the second roller.

[0015] Furthermore, a second fixing frame is embedded in the inner side of the counterweight plate, and a plurality of third rollers are rotatably connected inside the second fixing frame. The third rollers are in rolling connection with the inner side of the guardrail body.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the second fixing frame and the third roller on the inner side of the counterweight plate are rolledly connected to the inner side of the guardrail body, forming a three-point support with the first roller and the second roller, making the device move more smoothly along the guardrail, while enhancing the fit between the counterweight plate and the guardrail and improving the stability of the overall structure.

[0017] Furthermore, it also includes an installation mechanism, which includes a plurality of clamping blocks. The clamping blocks are evenly distributed on the outer side of the baffle. Both ends of the clamping blocks are threaded with adjusting bolts. One end of each adjusting bolt is rotatably connected to the outer side of the baffle. Anti-slip pads are installed on the inner side of each clamping block.

[0018] The beneficial effects of adopting the above-mentioned further solution are that the clamping block of the installation mechanism is fixed to the outside of the baffle by adjusting bolts, which can clamp the waterproof cloth; the anti-slip rubber pad enhances the clamping force of the clamping block and prevents the waterproof cloth from falling off; the adjusting bolts make it easy to adjust the clamping force according to the material thickness, thus improving the flexibility of protection.

[0019] Furthermore, the length of the main board, baffle, and counterweight plate is 5 to 10 meters, and the main board, baffle, and counterweight plate are all made of stainless steel.

[0020] The advantages of adopting the above-mentioned further solutions are that the main board, baffle and counterweight plate are designed with a length of 5 to 10 meters, which can cover a longer section of guardrail and increase the protection distance; the stainless steel material is corrosion resistant and has high strength, and can withstand the sun, rain and impact of the construction environment, which can extend the service life of the device and reduce maintenance costs.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: The main board of this highway pavement construction concrete guardrail pollution prevention device is mounted on the guardrail body via the rotating shaft of the mounting frame and the first roller, facilitating movement along the guardrail. The baffle and counterweight plate are hinged to both sides of the main board, and a tension spring connects the first movable seat and the second movable seat, providing inward tension to the baffle and counterweight plate, making them fit against the side of the guardrail. By installing a waterproof cloth on the mounting mechanism on one side of the baffle, asphalt splashes during construction can be blocked. The counterweight plate balance device prevents tipping, achieving efficient protection of the guardrail body, avoiding pollution, and facilitating movement. The second roller inside the first fixed frame is connected to the outer side of the guardrail body. The rolling connection converts the sliding friction between the baffle and the guardrail body into rolling friction, reducing movement resistance and making the device move more smoothly along the guardrail. It also limits the baffle's offset, ensuring a stable protection range. The second fixing frame and third roller on the inner side of the counterweight plate are rollingly connected to the inner side of the guardrail body, forming a three-point support with the first and second rollers. This makes the device move more smoothly along the guardrail and enhances the fit between the counterweight plate and the guardrail, improving the overall structural stability. The clamping block of the installation mechanism is fixed to the outside of the baffle by adjusting bolts and can hold the waterproof cloth. Anti-slip rubber pads enhance the clamping force of the clamping block, preventing the waterproof cloth from falling off. The adjusting bolts allow for adjustment of the clamping force according to the material thickness, improving the flexibility of protection. Attached Figure Description

The clamping blocks 301 of the installation mechanism 3 are fixed to the outside of the baffle 206 by adjusting bolts 302, and can clamp the waterproof cloth. The anti-slip pads enhance the clamping force of the clamping blocks 301 and prevent the waterproof cloth from falling off. The adjusting bolts 302 facilitate the adjustment of the clamping force according to the material thickness, improving the flexibility of protection.

[0032] As an embodiment of this utility model, the main board 201, baffle 206 and counterweight plate 205 are 5 to 10 meters long. The main board 201, baffle 206 and counterweight plate 205 are all made of stainless steel.

The main board 201 of the protective mechanism 2 is mounted on the upper end of the guardrail body 1 via the rotating shaft 203 of the mounting frame 202 and the first roller 204. The tension spring 213 pulls the baffle 206 against the counterweight plate 205 on both sides of the guardrail via the first movable seat 212 and the second movable seat 211, balancing the center of gravity of the guardrail. When moving the device, the first roller 204 moves along the guardrail... The upper part of the guardrail rolls, the second roller 209 of the first fixing frame 208 inside the baffle 206 rolls with the outer side of the guardrail, and the third roller 215 of the second fixing frame 214 inside the counterweight plate 205 rolls with the inner side of the guardrail. The three work together to reduce resistance and ensure smooth movement. After the construction of a section of the road is completed, it is convenient for the user to push the device along the guardrail body 1 to the next construction section. The locking screw 216 and locking nut 210 fix the position of the first fixing frame 208 to ensure that the second roller 209 is in contact. The stainless steel main plate 201, baffle 206 and counterweight plate 205 are 5 to 10m long. During construction, they can be used with waterproof cloth to block asphalt splashing and achieve pollution protection for the guardrail body 1.
