Description

Technical Field

[0001] This utility model relates to an adjustable width limiting device for highway engineering. Background Technology

[0002] In the field of highway engineering and traffic management, width limiting devices are important facilities for ensuring the safety of road infrastructure and regulating vehicle traffic order. They are widely used in scenarios such as bridges, tunnel entrances, rural roads, and construction sections. Their core function is to limit the width of passing vehicles to prevent oversized vehicles from damaging the road structure and surrounding facilities, while reducing traffic congestion and the risk of safety accidents.

[0003] Most highway width restriction devices on the market are fixed structures, typically consisting of concrete blocks, steel frames, or fixed crash barriers. While these devices can achieve basic width restriction functions, they have significant limitations: First, the width restriction dimensions are fixed and cannot be flexibly adjusted according to traffic needs. When it is necessary to allow temporary passage for large engineering vehicles or emergency rescue vehicles, fixed width restriction devices often need to be removed or temporarily modified, which is not only cumbersome and time-consuming but also increases project costs. Second, most fixed width restriction devices do not integrate deceleration functions. When vehicles pass at high speeds, they are prone to rigid collisions with the width restriction structure, which can cause serious damage to the vehicles and may also cause the width restriction device to tip over or be damaged, leading to secondary accidents.

[0004] Therefore, there is an urgent need for an adjustable width limiting device for highway engineering that combines multiple advantages such as flexible adjustment, stability and reliability, safety protection and convenient operation, in order to meet the diverse needs of modern highway traffic management. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an adjustable width limiting device for highway engineering that has multiple advantages such as flexible adjustment, stability and reliability, safety protection and convenient operation.

[0006] To solve the above problems, the present invention adopts the following technical solution: An adjustable width limiting device for highway engineering includes a deceleration device installed on the ground and a width limiting mechanism slidably installed through the deceleration device. Two width limiting mechanisms are provided, the distance between the two width limiting mechanisms is adjustable, and they are locked after adjustment.

[0007] Preferably, the deceleration device includes a base and a deceleration body, the base and the deceleration body are fixed by expansion bolts, the lower end of the expansion bolts is inserted into the ground for fixation, the top of the base is provided with a sliding groove, the sliding groove passes through the base laterally, the deceleration body is divided into left and right parts, and a groove corresponding to the sliding groove is formed between the left and right parts of the deceleration body, and the width limiting mechanism slides along the sliding groove.

[0008] Preferably, the surface of the deceleration body is provided with interlaced anti-slip grooves.

[0009] Preferably, the slide groove is inverted T-shaped to limit the width limiting mechanism to slide only laterally along the slide groove.

[0010] Preferably, the width limiting mechanism includes a base plate and a crash barrier. A slider is provided at the bottom axis of the base plate, and the slider slides in conjunction with the slide groove. An inner tube is provided at the top axis of the base plate, and a locking screw is screwed into the bottom of the inner tube. The locking screw passes through the slider and abuts against the bottom of the slide groove to lock the base plate. A tube cap is installed at the opening of the inner tube. A fixing ring is coaxially provided at the top of the base plate. The crash barrier is annular with a water-filled cavity inside. The crash barrier is fitted over the fixing ring. A water-filling hole communicating with the cavity is provided at the top of the crash barrier, and a hole cap is detachably installed in the water-filling hole.

[0011] Preferably, multiple rollers are provided at the bottom of the base plate, and the rollers roll and support the ground.

[0012] Preferably, a protective shell made of elastic rubber is fitted over the outside of the anti-collision barrel.

[0013] Preferably, the protective shell has multiple annular energy-absorbing sections.

[0014] Preferably, a counterweight is filled between the anti-collision barrel and the inner tube.

[0015] Preferably, the counterweight is a mixture of sand and gravel.

[0016] The beneficial effects of this utility model are: Firstly, the device employs a combined structure of a "deceleration device + sliding width-limiting mechanism." The two width-limiting mechanisms can slide laterally along the groove of the deceleration device, allowing for flexible adjustment of the spacing. This enables rapid adjustment of the width-limiting size based on the dimensions of vehicles used in daily traffic and temporary emergency passage needs (such as emergency rescue vehicles or engineering vehicles). After adjustment, the base plate is locked in place using locking screws, ensuring stable fixation of the width-limiting mechanism and preventing abnormal movement. Compared to traditional fixed width-limiting devices, this device can adapt to different scenarios without dismantling or modification, significantly improving its versatility and flexibility, and reducing the time and engineering costs associated with temporary adjustments.

[0017] Secondly, the device integrates the deceleration unit and the width-limiting mechanism into a single design. The deceleration unit is positioned across the road, and vehicles must pass over it to passively achieve a deceleration effect, effectively preventing vehicles from impacting the width-limiting mechanism at high speed and reducing the risk of collisions at the source. Simultaneously, the surface of the deceleration unit features crisscrossing anti-slip grooves, significantly increasing the friction between the tires and the deceleration unit. Especially in adverse weather conditions such as wetness or icy conditions, this effectively reduces vehicle slippage and further enhances traffic safety.

[0018] Thirdly, the device's structural design ensures stability in multiple ways: First, the base of the deceleration device is made of steel, with high structural strength, and is fixed to the ground with expansion bolts to ensure a firm overall installation; Second, the slide adopts an inverted T-shaped design, which precisely matches the slider of the width limiting mechanism, limiting the width limiting mechanism to only slide laterally, avoiding deviation or shaking during adjustment, and improving structural stability; Third, the width limiting mechanism increases its self-weight and stability in multiple ways. The inside of the anti-collision barrel is a water-filled cavity, and a sand and gravel mixture is filled between the anti-collision barrel and the inner tube as a counterweight, significantly improving the impact resistance of the width limiting mechanism and preventing it from tipping over or shifting when impacted.

[0019] Fourthly, the device features a multi-layered protective structure designed for different collision scenarios, providing dual protection for both the vehicle and the device itself: Firstly, when the crash barrier is impacted, it can absorb collision energy through deformation and rupture, reducing rigid impact damage to the vehicle; secondly, the crash barrier is encased in a protective shell made of elastic rubber, and the annular energy-absorbing part on the shell can effectively buffer the impact force of minor scratches, preventing damage to the vehicle from minor scratches and protecting the crash barrier from rupture due to minor collisions, thus reducing maintenance costs; thirdly, multiple rollers are installed at the bottom of the base plate, ensuring structural stability while making the sliding adjustment of the width limiting mechanism easier and more convenient, reducing the difficulty of operation.

Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, in the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "socket," "connect," "through," and "plug-in" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] See Figure 1 and Figure 2 The adjustable width limiting device for highway engineering shown includes a deceleration device 1 installed on the ground and a width limiting mechanism 2 slidably installed through the deceleration device 1. There are two width limiting mechanisms 2, the distance between the two width limiting mechanisms 2 is adjustable, and they are locked after adjustment.

[0028] In the above technical solution, the deceleration device 1 can span across the road so that the vehicle is passively decelerated when it is moving, so as to avoid the vehicle passing through the width restriction device at too high speed and reduce the risk of high-speed impact with the width restriction mechanism 2.

[0029] The spacing between the two width-limiting mechanisms 2 is adjustable, allowing for flexible adjustments based on traffic needs.

[0030] See Figure 3 As shown, the deceleration device 1 includes a base 11 and a deceleration body 12. The base 11 and the deceleration body 12 are fixed by expansion bolts 18. The lower end of the expansion bolts is inserted into the ground for fixation. A sliding groove 13 is provided on the top of the base 11. The sliding groove 13 extends horizontally through the base 11. The deceleration body 12 is divided into left and right parts. A groove 14 corresponding to the sliding groove 13 is formed between the left and right parts of the deceleration body 12. The width limiting mechanism 2 slides along the sliding groove 13.

[0031] The deceleration body is made of hard rubber and is obtained through injection molding, while the base 11 is made of steel and has high structural strength.

[0032] See Figure 3 As shown, the surface of the deceleration body 12 is provided with intersecting anti-slip grooves 121.

[0033] The purpose of anti-skid groove 121 is to increase the friction between the vehicle and the tire when the vehicle passes over it, thereby reducing the possibility of the vehicle skidding and moving sideways.

[0034] See Figure 3 As shown, the slide groove 13 is inverted T-shaped to limit the width limiting mechanism 2 to slide laterally along the slide groove 13.

[0035] This technical solution uses an inverted T-shaped groove 13 to restrict the width limiting mechanism 2 to a certain extent, thereby increasing the stability of the width limiting mechanism 2.

[0036] See Figure 2 and Figure 3 As shown, the width limiting mechanism 2 includes a base plate 21 and a crash barrier 22. A slider 23 is provided at the bottom axis of the base plate 21, and the slider 23 slides in conjunction with the slide groove 13. An inner tube 24 is provided at the top axis of the base plate 21, and a locking screw 25 is screwed into the bottom of the inner tube 24. The locking screw 25 passes through the slider 24 and abuts against the bottom of the slide groove 13 to lock the base plate 21. A tube cap 241 is installed at the opening of the inner tube 24. A fixing ring 26 is coaxially provided at the top of the base plate 21. The crash barrier 22 is annular and has a water-filled cavity 221 inside. The crash barrier 22 is fitted over the fixing ring 26. A water-filling hole communicating with the cavity is provided at the top of the crash barrier 22, and a hole cap 222 is detachably installed in the water-filling hole.

[0037] In the above technical solution, the anti-collision barrel 22 is made of PVC material. The internal weight is increased by filling water to increase the impact resistance. At the same time, it can deform and break after being impacted to absorb energy and protect the vehicle.

[0038] By screwing in the locking screw 25, the position of the base plate 21 is locked to prevent abnormal movement.

[0039] See Figure 3 As shown, multiple rollers 211 are provided at the bottom of the base plate 21, and the rollers 211 roll and support the ground.

[0040] The use of rollers 211 makes it easier for the base plate 21 to slide along the ground.

[0041] See Figure 3 As shown, a protective shell 223 made of elastic rubber is fitted over the outside of the anti-collision barrel 22.

[0042] The protective outer shell 223 has multiple annular energy-absorbing parts 224.

[0043] The above technical solution is mainly designed to address minor scratches when vehicles pass by, reducing vehicle damage caused by minor scratches between vehicles, and also protecting the crash barrier 22 to prevent breakage due to minor scratches.

[0044] See Figure 2 As shown, a counterweight 27 is filled between the anti-collision barrel 22 and the inner tube 24.

[0045] The counterweight is a mixture of sand and gravel.

[0046] In the above technical solution, the weight of the width limiting mechanism 2 can be further increased by filling with counterweight 27, so as to increase the stability under impact.
