Description

Technical Field

[0001] This utility model relates to the field of road and bridge technology, and in particular to a guardrail for urban roads and bridges that is easy to install. Background Technology

[0002] Urban roads and bridges are roads that connect different parts of a city, serving as transportation and pedestrian access within the city, facilitating residents' lives, work, and cultural and recreational activities, and connecting with roads outside the city to bear external traffic. Guardrails are used on roads to separate motor vehicle lanes and non-motor vehicle lanes, as well as pedestrian walkways. Guardrails are a type of traffic safety facility installed on the outer side of the road shoulder, traffic dividers, and pedestrian curbs.

[0003] Existing technologies, such as Chinese Patent Publication No. CN221663515U, disclose a conveniently installed guardrail for urban roads and bridges, including a base and posts. A material inlet is provided on one side of the upper part of the base, and a sealing plug is fitted inside the inlet. A post is fixed on top of the base. This conveniently installed guardrail for urban roads and bridges, through the coordinated use of the base, inlet, sealing plug, mounting sleeve, sliding groove, fixing rod, fixing ring, and slider, allows for rapid on-site installation by injecting sand and water (or other counterweights) into the cavity of the base through the inlet. It can be quickly deployed in emergency situations and tidal flow lanes on urban roads and bridges. The slider on the guardrail is slid into the sliding groove, the fixing rod is inserted, and the fixing ring is screwed onto the end of the fixing rod, allowing for quick connection between the post and the guardrail. This convenient installation effectively reduces the labor intensity of workers installing the device. However, this utility model is not convenient for adjusting the installation angle between multiple guardrails, making installation and adjustment time-consuming and labor-intensive when facing different complex road conditions.

[0004] To address the issue of the difficulty in adjusting the installation angles between multiple guardrails for urban roads and bridges according to road conditions, existing equipment makes it inconvenient to adjust the installation angles between multiple guardrails during installation. This makes the guardrails more suitable for installation on straight road sections, but difficult to install quickly in various complex road conditions. Often, the guardrail positions need to be adjusted repeatedly, which is time-consuming and labor-intensive. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the existing technology that it is not convenient to adjust the installation angle between multiple guardrails according to road conditions, and to propose a guardrail for urban roads and bridges that is easy to install.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a conveniently installed guardrail for urban roads and bridges, comprising a mounting base, a mounting post, a guardrail, and an installation device. The mounting post is fixedly connected to the top surface of the mounting base. The guardrail is disposed on the surface of the mounting post. The installation device is disposed on the surface of the mounting post. The installation device includes an adjustment component, a fixing component, and an auxiliary component. The adjustment component includes a slot, which is formed on the top surface of the mounting post. A groove is formed on the top surface of the mounting post, and the groove communicates with the slot. A retaining plate is fixedly connected to the surface of the guardrail, and the retaining plate is slidably connected to the surface of the groove. A rod is fixedly connected to the surface of the retaining plate, and the rod is slidably connected to the surface of the slot.

[0007] Furthermore, the number of mounting columns is two sets arranged symmetrically, the number of slots is multiple and distributed circumferentially, and the number of mounting plates is two sets arranged symmetrically.

[0008] Furthermore, the fixing component includes a limiting rod, which is fixedly connected to the top surface of the mounting column, and a top cover is slidably connected to the surface of the limiting rod, the top cover being adapted to the slot.

[0009] Furthermore, an anti-detachment disc is fixedly connected to the top surface of the limiting rod, a movable disc is slidably connected to the surface of the limiting rod, and a spring is sleeved and connected to the surface of the limiting rod.

[0010] Furthermore, one end of the spring is fixedly connected to the surface of the anti-detachment disc, and the other end of the spring is fixedly connected to the surface of the movable disc.

[0011] Furthermore, the auxiliary component includes a dovetail groove, which is formed on the surface of the guardrail. There are two sets of dovetail grooves arranged symmetrically, and dovetail blocks are slidably connected to the surface of the dovetail groove.

[0012] Furthermore, a counterweight plate is fixedly connected to the surface of the dovetail block, and an identification plate is fixedly installed on the surface of the counterweight plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting up an installation device, two sets of mounting seats and one set of guardrails are used. First, the top cover is held and lifted upward along the limiting rod, so that the movable plate is upward and the spring is compressed. After the top cover is disengaged from the slot, it is rotated half a turn along the limiting rod to ensure that it does not obstruct the slot. Then, the insert rods on both sides of the guardrail are inserted into the slots of the mounting posts on the two sets of mounting seats respectively. Then, the above operation is repeated to reset the top cover to fix the guardrail. Modular and convenient installation can be achieved by using multiple sets of mounting seats and guardrails. When it is necessary to change the angle of the guardrail, simply adjust the position of the card plate while inserting the insert rod into the slot so that it is inserted into the corresponding angle slot. A counterweight plate and a sign plate can also be used. The dovetail blocks on them are slid down from the top of the guardrail along the dovetail groove to increase the weight of the guardrail and at the same time provide simple road information marking.

[0014] 2. In this utility model, by setting up an installation device, the modular approach facilitates the rapid installation and fixing of the guardrail, and the angles between multiple guardrails can be easily adjusted to adapt to complex road conditions. Furthermore, the counterweights and markings on the guardrails can be added as needed, thus effectively improving the applicability of the equipment. Attached Figure Description

[0017] Please see Figures 1-5This utility model provides a technical solution: a convenient-to-install guardrail for urban roads and bridges, including a mounting base 1, a mounting post 2, a guardrail 3, and an installation device 4. The mounting post 2 is fixedly connected to the top surface of the mounting base 1, the guardrail 3 is set on the surface of the mounting post 2, and the installation device 4 is set on the surface of the mounting post 2.

[0018] The specific setup and function of its installation device 4 will be described in detail below.

[0019] In this embodiment: the installation device 4 includes an adjustment component 41, a fixing component 42 and an auxiliary component 43. The adjustment component 41 includes a slot 411, which is opened on the top surface of the mounting post 2. The top surface of the mounting post 2 is provided with a slot 412, which is connected to the slot 411. A card plate 413 is fixedly connected to the surface of the guardrail 3. The card plate 413 is slidably connected to the surface of the slot 412. A rod 414 is fixedly connected to the surface of the card plate 413, which is slidably connected to the surface of the slot 411.

[0020] The effect achieved by the above components is as follows: the slot 411, the groove 412, the plate 413 and the rod 414 are designed to facilitate the fixing of the guardrail 3 to the mounting post 2 on the mounting base 1. Simply insert the rod 414 into the slot 411 from above, and at the same time, the plate 413 is inserted into the groove 412 at the corresponding angle, so that quick and stable installation can be achieved.

[0021] Specifically, there are two sets of mounting columns 2 arranged symmetrically, multiple slots 412 arranged in a circular pattern, and two sets of mounting plates 413 arranged symmetrically.

[0022] The effects achieved by the above components are as follows: setting multiple slots 412 is so that when inserting the rod 414 into the slot 411, the installation angle between the guardrail 3 and the mounting post 2 can be changed simply by inserting the plate 413 into different slots 412. By using multiple guardrails 3 and mounting bases 1 to cooperate at different angles, different complex road conditions can be dealt with. Setting two sets of mounting posts 2 and plates 413 is so that the guardrail 3 can be installed on two sets of mounting bases 1 on both sides. Modular installation is achieved by using multiple guardrails 3 and mounting bases 1.

[0023] Specifically, the fixing component 42 includes a limiting rod 421, which is fixedly connected to the top surface of the mounting post 2. A top cover 422 is slidably connected to the surface of the limiting rod 421, and the top cover 422 is adapted to the slot 411.

[0024] The effects achieved by the above components are as follows: the limiting rod 421 is set to restrict and guide the movement of the top cover 422, and the top cover 422 is set to fix the insertion rod 414 inserted into the slot 411, preventing it from sliding upward out of the slot 411 at will, thereby achieving the fixation of the guardrail 3.

[0025] Specifically, an anti-detachment disc 423 is fixedly connected to the top surface of the limiting rod 421, a movable disc 424 is slidably connected to the surface of the limiting rod 421, and a spring 425 is sleeved and connected to the surface of the limiting rod 421.

[0026] The effects achieved by the above components are as follows: the anti-detachment disc 423 is set to prevent the top cover 422 from detaching from the limiting rod 421, and the movable disc 424 is set to facilitate the compression of the top cover 422 with the spring 425. This not only allows the top cover 422 to press the insertion rod 414 to prevent it from moving at will, but also does not affect the operation of moving and rotating the top cover 422.

[0027] Specifically, one end of the spring 425 is fixedly connected to the surface of the anti-detachment disc 423, and the other end of the spring 425 is fixedly connected to the surface of the movable disc 424.

[0028] The effect achieved by the above components is as follows: the spring 425 is set so that the top cover 422 can lock the plug rod 414 to prevent accidental contact that would cause the guardrail 3 to move at will, and its rebound force can also facilitate the reset of the top cover 422.

[0029] Specifically, the auxiliary component 43 includes a dovetail groove 431, which is formed on the surface of the guardrail 3. There are two sets of dovetail grooves 431 arranged symmetrically, and a dovetail block 432 is slidably connected to the surface of the dovetail groove 431.

[0030] The effect achieved by the above components is that the dovetail groove 431 and the dovetail block 432 are provided to facilitate the convenient insertion of the counterweight plate 433 from above the guardrail 3, and to allow it to be pulled out only when the force is upward.

[0031] Specifically, a counterweight plate 433 is fixedly connected to the surface of the dovetail block 432, and an identification plate 434 is fixedly installed on the surface of the counterweight plate 433.

[0032] The effects achieved by the above components are as follows: the counterweight plate 433 is set to increase the weight of the guardrail 3 to maintain sufficient stability, and the sign plate 434 is set to facilitate simple marking of road information.

[0033] Working principle: By setting up the installation device 4, take two sets of mounting bases 1 and one set of guardrails 3. First, hold the top cover 422 and lift it upward along the limiting rod 421, so that the movable plate 424 moves upward and compresses the spring 425. After the top cover 422 is disengaged from the slot 411, rotate it half a turn along the limiting rod 421 to ensure that it does not obstruct the slot 411. Then, insert the insert rods 414 on both sides of the guardrail 3 into the slots 411 of the mounting posts 2 on the two sets of mounting bases 1 respectively. Then repeat the above operation to reset the top cover 422. The guardrail 3 is fixed in place. Modular and convenient installation can be achieved by using multiple sets of mounting bases 1 and guardrail 3. When it is necessary to change the angle of guardrail 3, simply adjust the position of the card plate 413 so that it is inserted into the corresponding angle slot 412 while inserting the plug 414 into the slot 411. The counterweight plate 433 and the marking plate 434 can also be used. The dovetail block 432 on them can be used to slide down from the top of the guardrail 3 along the dovetail groove 431 to increase the weight of the guardrail 3 and at the same time to mark the road information.

[0034] By setting up the installation device 4, the modular approach facilitates the quick installation and fixation of the guardrail 3, and allows for convenient adjustment of the angles between multiple guardrails 3 to adapt to complex road conditions. Furthermore, it allows for the addition of counterweights and markings on the guardrails 3 as needed, thus effectively improving the applicability of the equipment.
