Description

Technical Field

[0001] The present invention specifically relates to an anti-collision device for a highway reconstruction and expansion project and an installation method thereof, and belongs to the technical field of highway anti-collision devices. Background Art

[0002] In the early days, there were few highways built. In order to meet the needs of traffic growth in these areas, the existing highways were widened and rebuilt. When the highway was expanded, in order to protect the moving cars and construction workers, guardrails must be used to isolate the construction area. At present, in order to reduce the possibility of vehicles mistakenly entering the construction area and causing danger, temporary guardrails are usually placed to enclose the construction area. However, the anti-collision ability of temporary guardrails is relatively low. When a car on the highway deviates from the lane or loses control, it causes the vehicle to rush towards the temporary guardrail. Due to the high speed of the car, the temporary guardrail has poor anti-collision ability, which increases the risk of accidents for the workers in the construction area of ​​the highway. For this reason, China Patent Publication No.: CN114 718380A, discloses an anti-collision device for highway reconstruction and expansion projects and an installation method thereof, the structure can improve the stability of the protective plate body when in use, and a rotating seat and an arc frame are arranged at one end of the movable rod, which can fix the front wheel of the car when the protective plate body collides when the car loses control; another example is the authorization announcement number: CN113775241B, which discloses an anti-collision device for highway reconstruction and expansion projects, the structure can improve the protective effect of the guardrail on the construction area; but the above structures have general anti-collision force decomposition capabilities, and are all fixed-position anti-collision structures. Since the construction area is continuously changing, the above structures cannot follow the construction workers to protect them. Summary of the invention

[0003] In order to solve the above problems, the present invention proposes an anti-collision device and an installation method for highway reconstruction and expansion projects, which can move with the construction location, and continuously maintain anti-collision capability during the movement. A frame structure is used to protect the construction area, and the anti-collision capability is strong.

[0004] The anti-collision device for highway reconstruction and expansion engineering of the present invention comprises: A tire limiting unit, the tire limiting unit comprising a beam plate, a plurality of force unloading arrays are arranged at intervals on the front side of the beam plate; The vehicle body limiting unit comprises a plurality of guardrail plates, wherein rubber rollers are rotatably arranged between the guardrail plates through guide pillars; a row of backing beams are fixed at intervals on the back of the guardrail plates; and the bottom of the backing beams are respectively fixed to the beam plate and the rear side of the unloading array; When a vehicle hits the anti-collision device at a certain angle, the front of the vehicle contacts the rubber roller, the front of the vehicle rubs against the rubber roller, the rubber roller rotates, and the vehicle's driving path is corrected, so that the angle of attack between the vehicle and the guardrail is reduced, even if the vehicle tends to move in the direction parallel to the length of the guardrail; the front impact force of the anti-collision device is reduced, and at the same time, when the front of the vehicle contacts the rubber roller, the wheels synchronously contact the force unloading array, and the wheels decompose the impact force through the force unloading array. At the same time, through the elastic deformation of the rubber roller, the overall impact force of the vehicle can be decomposed and unloaded; the anti-collision device realizes anti-collision deformation at the front end through the above structure, which can reduce the impact force at the rear end of the entire anti-collision device; The positioning walking unit comprises a channel steel, sealing plates are fixed at both ends of the channel steel, multiple groups of positioning units are arranged inside the channel steel, and an electromagnetic suction cup is fixed in the middle of the positioning unit; an automatic power moving vehicle is fixed at the bottom of the positioning unit, and hydraulic diagonal braces are fixed on both sides of the automatic power moving vehicle; When the positioning walking unit is moving, the electromagnetic suction cup of the positioning unit at the odd position is pre-magnetically clamped with the channel steel, and the electromagnetic suction cup of the positioning unit at the even position is powered off. At the same time, the hydraulic diagonal brace of the positioning unit at the even position is gripped with the ground, and the power moving vehicle of the positioning unit at the odd position moves, driving the channel steel to move synchronously. When the channel steel moves to the set distance, the hydraulic diagonal brace at the odd position is gripped with the ground; the electromagnetic suction cup at the odd position is powered off, and the electromagnetic suction cup at the even position is powered on. Then, the hydraulic diagonal brace at the even position is retracted, so that the automatic power moving vehicle drives the positioning unit at the even position to drive the channel steel to move in a straight line. After walking to the right position, the hydraulic diagonal brace at the even position is controlled to extend, so that the hydraulic diagonal brace is gripped with the ground again; Guide seats, the guide seats are provided in four groups, two groups of the guide seats are fixed at both ends of the beam plate; the other two groups of the guide seats are fixed at both ends of the channel steel; The connecting bridge comprises a front connecting bridge and a rear connecting bridge.

After the connecting bridge and the guide seat are fitted and locked by bolts, the tire limit unit, the body limit unit, the adjustment walking unit and the connecting bridge can form a three-dimensional enclosure space. The front connecting bridge serves as a supporting component of the power system; the ramp of the rear connecting bridge can serve as a guide for engineering vehicles to enter and exit the construction area; at the same time, it serves as an anti-collision support system; A fixed walking unit is arranged at both ends of the vehicle body limiting unit, and the fixed walking unit includes a positioning box fixed to the outside of the guide seat, an elastic buffer unit is arranged on the inner side of the positioning box, and an automatic power moving vehicle is fixed to the bottom of the elastic buffer unit; when the positioning walking unit moves, the fixed walking unit can move synchronously, thereby driving the entire three-dimensional enclosed space to move synchronously, and the hydraulic diagonal brace of the fixed walking unit can serve as a position limit for the front end to resist impact and deformation.

[0005] Furthermore, the force unloading array includes a force-bearing platform fixed to the beam plate by bolts, a blow molding box is fixed to the front side of the force-bearing platform, an impact platform is arranged on the front side of the blow molding box, hinge seats are fixed to the upper and lower parts of both sides of the force-bearing platform, and arc-shaped steel bars are hinged between adjacent hinge seats; the upper and lower arc-shaped steel bars face opposite directions; the inner side of the blow molding box is filled with an elastomer; a right-angle opening is opened at the bottom of the supporting beam, and the right-angle opening is clamped to the beam plate and the top surface of the force-bearing platform; when the vehicle tire impacts the force unloading array, it first contacts the impact platform, The vehicle tire impacts the tire forward. At this time, due to the limitation between the impact platform and the force-bearing platform, the curved steel bar undergoes elastic deformation, and the impact force is decomposed once until the impact platform contacts the blow molding box. When the blow molding box is deformed or damaged by the impact, the elastomer inside the blow molding box is squeezed and deformed, and the impact force is decomposed for a second time.

When the channel steel moves, the toothed disc of the hydraulic diagonal brace grips the ground, so that the automatic power moving vehicle can be kept in this position unchanged until the hydraulic diagonal brace retracts, and it can move freely along the channel steel.

[0036] The unloading array includes a force-bearing platform 19 fixed to the beam plate 1 by bolts, a blow molding box 20 is fixed to the front side of the force-bearing platform 19, and an impact platform 21 is arranged on the front side of the blow molding box 20.
