Description

Technical Field

[0001] This utility model relates to the field of road barrier technology; more specifically, it relates to a road barrier for highway maintenance and construction. Background Technology

[0002] Highway maintenance and construction refers to engineering activities that systematically maintain, repair, and improve highways and their ancillary facilities. The aim is to maintain or enhance the technical condition and service functions of highways, and ensure driving safety and traffic efficiency. Highway maintenance and construction covers preventive maintenance, restorative repair, reinforcement and improvement, and expansion projects, including the maintenance of all elements such as pavement, roadbed, bridges, tunnels, and traffic facilities.

[0003] Road barriers used for highway maintenance and construction are facilities used to temporarily separate traffic flow, guide traffic, and protect the safety of the construction site. By temporarily setting up isolation areas through road barriers, vehicles are guided to detour around dangerous road sections or construction areas, preventing vehicles from accidentally entering the work area and causing accidents, while also protecting the safety of construction personnel and equipment.

[0004] Currently, existing road barriers suffer from several drawbacks. Firstly, they are mostly placed directly for use, making it difficult to display warning messages based on actual conditions or to change the warning messages. This reduces the practicality of the equipment. Secondly, existing road barriers are mostly placed independently, resulting in poor connectivity between devices and reduced stability. Pedestrians may pass through gaps between the barriers. Therefore, there is an urgent need for a road barrier specifically designed for highway maintenance and construction to address these issues. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a road barrier for highway maintenance and construction, so as to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a road barrier for highway maintenance and construction, comprising:

[0007] The base plate has threaded support rods threadedly connected to the interior of each of its four corners. Support piles are fixedly connected to the upper surface of the base plate, and rubber pads are engaged with the outer surfaces of both sides of the support piles. Warning structures are provided inside the support piles, and connecting structures are provided on the outer surfaces of both ends of the support piles. The warning structure includes two sets of fixing sleeves, each set fixedly connected to the outer surface of the upper end of both ends of the support pile. The connecting structure includes a first connecting plate and a second connecting plate, with the surfaces of the first and second connecting plates, close to each other, fixedly connected to the outer surfaces at the midpoints of both ends of the support pile.

[0008] Preferably, rectangular slots are provided inside the two sides of the support pile, and rectangular inserts are provided on the inner wall surfaces of the two ends of the rubber pad. The outer dimensions of the rectangular inserts are the same as the inner dimensions of the rectangular slots. The inner wall surface of the rubber pad is in contact with the outer surface of the support pile, and the rubber pad is made of rubber. This design can buffer and relieve force to a certain extent when the equipment is subjected to external force by means of the elasticity and toughness of the rubber pad itself.

[0009] Preferably, a positioning rod is inserted inside the fixed sleeve, and a first spring is fitted on the outer surface of the positioning rod. A warning frame is inserted inside the support pile, and a first positioning hole is opened inside the upper part of both ends of the warning frame, and a second positioning hole is opened inside the lower part of both ends of the warning frame. Insertion slots are opened inside the upper two sides of the warning frame, and warning plates are inserted inside the insertion slots. This design can warn passing vehicles and pedestrians through the warning plates.

[0010] Preferably, the outer surface of the positioning rod is provided with a limiting ring, and the outer dimensions of the limiting ring are adapted to the inner dimensions of the fixed sleeve. The two ends of the first spring respectively abut against one side surface of the limiting ring and the inner wall surface of one end of the fixed sleeve. This design makes the positioning rod more stable when it moves and can prevent the positioning rod from detaching from the inside of the fixed sleeve.

[0011] Preferably, a limiting plate is provided on the outer surface of the lower end of the warning frame, and the external dimensions of the limiting plate are adapted to the internal dimensions of the support pile. The position of the positioning rod corresponds to the position of the first positioning hole and the second positioning hole, and the external dimensions of one end of the positioning rod are adapted to the internal dimensions of the first positioning hole and the second positioning hole. This design can prevent the warning frame from detaching from the inside of the support pile.

[0012] Preferably, a connecting groove is provided inside one end of the first connecting plate, and a moving groove is provided on the inner wall surface of both sides of the connecting groove. A receiving groove is provided at the bottom of the inner wall surface at both ends of the connecting groove. A connecting sleeve is fixedly connected to the upper surface of one end of the second connecting plate, and a connecting rod is inserted into the inside of the connecting sleeve. A second spring is sleeved on the outer surface of the connecting rod, and connecting blocks are fixedly connected to the outer surfaces of both sides of the lower end of the connecting rod. This design allows the two sets of equipment to be connected through the connecting structure.

[0013] Preferably, the internal dimensions of the connecting groove are adapted to the external dimensions of the lower end of the connecting rod, the internal dimensions of the moving groove are adapted to the external dimensions of the connecting block, the internal dimensions of the storage groove are the same as the external dimensions of the connecting block, a support ring is provided on the outer surface of the connecting rod, and the external dimensions of the support ring are adapted to the internal dimensions of the connecting sleeve. The two ends of the second spring abut against the bottom surface of the support ring and the upper surface of the second connecting plate, respectively. This design allows the outer surface of the lower end of the connecting rod to be inserted into the connecting groove, and the outer surface of the connecting block to be completely inserted into the storage groove.

[0014] The technical effects and advantages of this utility model are as follows: This utility model positions the warning frame by pulling it upward and inserting the outer surface of one end of the positioning rod into the second positioning hole. At this time, the warning plate can warn pedestrians and vehicles. The warning plate can also be pulled out from the insertion slot for replacement, which makes it easy to change the warning content according to the actual situation, thus improving the practicality of the equipment to a certain extent.

[0015] By bringing the first connecting plate in one set of equipment close to the second connecting plate in another set of equipment, the position of the connecting block corresponds to the position of the moving slot. After pressing down the connecting rod and rotating the connecting rod, the position of the connecting block corresponds to the position of the receiving slot. At this time, the connecting rod is released, allowing the outer surface of the connecting block to be inserted into the inside of the receiving slot. This allows the connection between two or more sets of equipment to be completed, improving the connectivity between the equipment and enhancing stability to a certain extent. It also prevents pedestrians from passing through the gaps between the equipment. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The road barriers involved in this utility model are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1, as Figures 1-3 As shown in the figure, this embodiment proposes a road barrier for highway maintenance and construction, including:

[0024] The base plate 1 has threaded support rods 2 threadedly connected to the four corners of the base plate 1. The upper surface of the base plate 1 is fixedly connected to the support pile 3, and the outer surfaces of both sides of the support pile 3 are engaged with rubber pads 4. The support pile 3 has a warning structure 5 inside, and the outer surfaces of both ends of the support pile 3 have a connecting structure 6. The inner surfaces of both ends of the support pile 3 have rectangular slots. The inner surfaces of both ends of the rubber pad 4 have rectangular inserts, and the outer dimensions of the rectangular inserts are the same as the inner dimensions of the rectangular slots. The inner surface of the rubber pad 4 is in contact with the outer surface of the support pile 3, and the rubber pad 4 is made of rubber. This design allows the rectangular inserts to be fully inserted into the rectangular slots. When the rectangular inserts are inserted into the rectangular slots, the inner surface of the rubber pad 4 is in contact with the outer surface of the support pile 3. If the rubber pad 4 is subjected to an external impact, the elasticity and toughness of the rubber material itself can reduce the impact force through an energy absorption mechanism, thereby reducing the risk of damage to the vehicle and equipment. It also makes it easy to install or replace the rubber pad 4.

[0025] The warning structure 5 includes a fixing sleeve 51, and there are two sets of fixing sleeves 51. The two sets of fixing sleeves 51 are respectively fixedly connected to the outer surfaces of the upper ends of the support pile 3. A positioning rod 52 is inserted inside the fixing sleeve 51, and a first spring 53 is sleeved on the outer surface of the positioning rod 52. A warning frame 54 is inserted inside the support pile 3. A first positioning hole 55 is opened inside the upper surface of both ends of the warning frame 54, and a second positioning hole 56 is opened inside the lower surface of both ends of the warning frame 54. Insertion grooves 57 are opened inside the upper two sides of the warning frame 54. Furthermore, a warning plate 58 is inserted into the insertion slot 57, and a limit ring is provided on the outer surface of the positioning rod 52. The outer dimensions of the limit ring are adapted to the inner dimensions of the fixed sleeve 51. The two ends of the first spring 53 abut against one side surface of the limit ring and the inner wall surface of one end of the fixed sleeve 51, respectively. This design makes the positioning rod 52 more stable when it moves inside the fixed sleeve 51, and can prevent the positioning rod 52 from detaching from the inside of the fixed sleeve 51. After the positioning rod 52 is pulled and released, it can be automatically reset by the elasticity of the first spring 53.

[0026] A limiting plate is provided on the outer surface of the lower end of the warning frame 54, and the external dimensions of the limiting plate are adapted to the internal dimensions of the support pile 3. The position of the positioning rod 52 corresponds to the position of the first positioning hole 55 and the second positioning hole 56, and the external dimensions of one end of the positioning rod 52 are adapted to the internal dimensions of the first positioning hole 55 and the second positioning hole 56. This design makes the warning frame 54 more stable when moving inside the support pile 3, and can prevent the warning frame 54 from detaching from the support pile 3. This design also allows the outer surface of one end of the positioning rod 52 to be inserted into the first positioning hole 55 or the second positioning hole 56, thereby positioning the warning frame 54.

[0027] Example 2, as Figure 4 and Figure 5 As shown, based on the same concept as the above embodiments, this embodiment also proposes:

[0028] The connecting structure 6 includes a first connecting plate 61 and a second connecting plate 65. The surfaces of the first connecting plate 61 and the second connecting plate 65, located close to each other, are fixedly connected to the outer surfaces of the two ends of the support pile 3 at their midpoints. A connecting groove 62 is formed inside one end of the first connecting plate 61, and movable grooves 63 are formed on the inner wall surfaces of both sides of the connecting groove 62. A receiving groove 64 is formed at the bottom of the inner wall surfaces at both ends of the connecting groove 62. A connecting sleeve 66 is fixedly connected to the upper surface of one end of the second connecting plate 65, and a connecting rod 67 is inserted inside the connecting sleeve 66. The outer surface of 7 is fitted with a second spring 68, and the outer surfaces of both sides of the lower end of the connecting rod 67 are fixedly connected with connecting blocks 69. The internal dimensions of the connecting groove 62 are adapted to the external dimensions of the lower end of the connecting rod 67. The internal dimensions of the moving groove 63 are adapted to the external dimensions of the connecting block 69. The internal dimensions of the storage groove 64 are the same as the external dimensions of the connecting block 69. The outer surface of the connecting rod 67 is provided with a support ring, and the external dimensions of the support ring are adapted to the internal dimensions of the connecting sleeve 66. The two ends of the second spring 68 respectively abut against the bottom surface of the support ring and the upper surface of the second connecting plate 65.

[0029] In this embodiment, the design allows the outer surface of the lower end of the connecting rod 67 in one set of equipment to be inserted into the interior of the connecting slot 62 in another set of equipment, and the outer surface of the connecting block 69 to move within the moving slot 63. When the connecting rod 67 moves downward and causes the connecting block 69 to disengage from the interior of the moving slot 63, the connecting rod 67 can be rotated so that the position of the connecting block 69 corresponds to the position of the receiving slot 64. At this time, releasing the connecting rod 67 can cause the connecting rod 67 to move upward through the elasticity of the second spring 68, so that the outer surface of the connecting block 69 is inserted into the interior of the receiving slot 64, thereby completing the connection between two or more sets of equipment.

[0030] The threaded support rod 2, positioning rod 52, and connecting rod 67 in this application, as well as all movable parts, require regular cleaning and maintenance, including but not limited to dust removal and lubrication.

[0031] Working principle: When using the equipment, firstly, the equipment is moved to a suitable position by the casters on the bottom surface of the base plate 1. Then, the threaded support rod 2 is rotated so that the bottom surface of the threaded support rod 2 is pressed against the ground to position the equipment. Next, the two sets of positioning rods 52 are pulled outward to move the positioning rods 52 inside the fixed sleeve 51, so that the outer surface of one end of the positioning rod 52 is disengaged from the inside of the first positioning hole 55. At this time, the warning frame 54 moves upward inside the support pile 3. When the position of the second positioning hole 56 corresponds to the position of the positioning rod 52, the positioning rod 52 is released. The elasticity of the first spring 53 causes the positioning rod 52 to reset itself, and the outer surface of one end of the positioning rod 52 is inserted into the inside of the second positioning hole 56 to position the warning frame 54. At this time, the warning plate 58 can be used to warn pedestrians and vehicles. The warning plate 58 can be pulled out from the insertion slot 57 for replacement. The above operation can be reversed to put the warning frame 54 back in.

[0032] When using the equipment, bring the first connecting plate 61 of one set of equipment close to the second connecting plate 65 of another set of equipment, pull the connecting rod 67 upward to align the connecting rod 67 of the other set of equipment with the connecting groove 62 of the first set of equipment, and align the position of the connecting block 69 with the position of the moving groove 63. Then press the connecting rod 67 downward to insert the outer surface of the connecting rod 67 into the interior of the connecting groove 62, and disengage the connecting block 69 from the interior of the moving groove 63. Next, rotate the connecting rod 67 to align the position of the connecting block 69 with the position of the receiving groove 64. At this time, release the connecting rod 67, and the elasticity of the second spring 68 will drive the connecting rod 67 upward to insert the outer surface of the connecting block 69 into the interior of the receiving groove 64. This completes the connection between two or more sets of equipment. The connection between the equipment can be disassembled by reversing the above operations. This is the complete working principle of this utility model.

[0033] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.

[0034] Secondly: The accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
