Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, specifically a temporary road traffic guardrail. Background Technology

[0002] Traffic guardrails are traffic safety facilities installed on the outer side of road shoulders, traffic dividers, and sidewalk curbs. They absorb collision energy by deforming themselves or by allowing vehicles to climb, thereby changing the direction of vehicle travel, preventing vehicles from going off the road or entering the oncoming lane, and minimizing injury to occupants.

[0003] During road construction, it is often necessary to temporarily change traffic routes. At this time, temporary guardrails are needed to divide the traffic routes. In order to ensure the stability of the temporary guardrails, they are also fixed to the road surface with expansion bolts. However, the road construction process will adjust the route according to the construction progress. Therefore, the position of the temporary guardrails needs to be changed and adjusted frequently. After the expansion bolts are removed, the part of the bolt that protrudes from the road surface needs to be cut off with cutting equipment, which results in a large workload and affects the efficiency of changing the temporary guardrails. Based on this, a temporary road traffic guardrail is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a temporary road traffic guardrail in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a temporary road traffic guardrail, comprising a guardrail assembly consisting of a base, posts, connectors, railings, and T-shaped fixing holes. The posts are inserted into the top of the base and locked in place by bolts. The railings are installed and fixed between two adjacent posts by connectors. The T-shaped fixing holes are opened on the upper surface of the base and extend completely to the lower surface of the base. A detachable fixing component is installed inside the T-shaped fixing hole. The detachable fixing component is inserted into the mounting hole opened in the road surface to fix the base to the road surface.

[0006] The detachable fixing component includes a one-way self-locking unit and a disassembly unit;

[0011] The inclined locking block is rotatably connected to the bottom outer side of the T-shaped telescopic cylinder and extends through to the outside of the fixed cylinder column;

[0012] When the T-shaped plug-in tube is inserted through the T-shaped fixing hole and into the mounting hole, the inclined locking block fits against the inner wall of the mounting hole to limit the upward movement of the T-shaped plug-in tube.

[0013] As a further improvement of this utility model: the fixed cylinder column is provided with a through-hole for the inclined block to pass through at the contact position with the inclined block, and the T-shaped telescopic cylinder is provided with a rotation groove for the inclined block to rotate at the contact position with the inclined block.

[0014] The inclined blocks, through-holes, and rotating grooves are evenly arranged in multiple sets along the circumference.

[0015] As a further improvement of this utility model: the disassembly unit includes a T-shaped fixing post and a spring;

[0016] The T-shaped fixing column is fixed to the bottom middle of the inner wall of the fixing cylinder column and extends out to the top of the T-shaped insertion cylinder. The T-shaped telescopic cylinder is slidably sleeved with the vertical part of the T-shaped fixing column.

[0017] The spring is sleeved on the outside of the vertical part of the T-shaped fixed column and distributed between the bottom of the T-shaped telescopic cylinder and the bottom of the inner wall of the fixed cylinder. The spring is used to provide an upward thrust for the T-shaped telescopic cylinder.

[0018] As a further embodiment of this utility model: the outer diameter of the top circular portion of the T-shaped fixing column, the T-shaped telescopic cylinder, and the T-shaped plug-in cylinder increases sequentially, and the bottom of the top circular portion of the T-shaped fixing column has an arc surface structure.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5In this embodiment of the utility model, a temporary road traffic guardrail includes a guardrail assembly 1 consisting of a base 101, a post 102, a connector 103, a railing 104, and a T-shaped fixing hole 105. The post 102 is inserted into the top of the base 101 and locked in place by bolts. The railing 104 is installed and fixed between two adjacent posts 102 by the connector 103. The T-shaped fixing hole 105 is opened on the upper surface of the base 101 and completely penetrates to the lower surface of the base 101. A detachable fixing component 2 is installed on the inner side of the T-shaped fixing hole 105. The detachable fixing component 2 is inserted into the installation hole opened in the road surface to fix the base 101 to the road surface.

[0031] The detachable fixing component 2 includes a one-way self-locking unit and a disassembly unit. The one-way self-locking unit is used to achieve one-way self-locking with the mounting hole, thereby providing vertical limit for the base 101. The disassembly unit is used to achieve the unlocking and disassembly operation of the one-way self-locking unit.

[0032] The one-way self-locking unit includes a T-shaped plug-in cylinder 201, a fixed cylinder column 202, a T-shaped telescopic cylinder 204, and an inclined locking block 205;

[0033] The fixed cylinder 202 is fixed to the bottom of the T-shaped plug-in cylinder 201, and the T-shaped telescopic cylinder 204 passes through the inside of the fixed cylinder 202 from the top of the T-shaped plug-in cylinder 201. The T-shaped telescopic cylinder 204 is in a sliding connection with the T-shaped plug-in cylinder 201 and the fixed cylinder 202.

[0034] The tilting block 205 is rotatably connected to the bottom outer side of the T-shaped telescopic cylinder 204 and extends through to the outside of the fixed cylinder column 202;

[0035] When the T-shaped plug-in tube 201 is inserted into the T-shaped fixing hole 105 and into the mounting hole, the inclined locking block 205 fits against the inner wall of the mounting hole to limit the upward movement of the T-shaped plug-in tube 201.

[0036] A through-hole 207 is provided at the contact position between the fixed cylinder 202 and the inclined block 205 for the inclined block 205 to pass through, and a rotating groove 208 is provided at the contact position between the T-shaped telescopic cylinder 204 and the inclined block 205 for the inclined block 205 to rotate.

[0037] Multiple sets of inclined blocks 205, through openings 207, and rotating grooves 208 are evenly arranged along the circumference.

[0038] The disassembly unit includes a T-shaped fixing post 203 and a spring 206;

[0039] The T-shaped fixing post 203 is fixed to the bottom center of the inner wall of the fixing cylinder post 202 and extends out to the top of the T-shaped insertion cylinder 201. The T-shaped telescopic cylinder 204 is slidably sleeved with the vertical part of the T-shaped fixing post 203.

[0040] Spring 206 is sleeved on the outside of the vertical part of T-shaped fixed column 203 and distributed between the bottom of T-shaped telescopic cylinder 204 and the bottom of the inner wall of fixed column 202. Spring 206 is used to provide upward thrust for T-shaped telescopic cylinder 204.

[0041] In this embodiment, it should be noted that the interconnection structure of the base 101, post 102, connector 103, and railing 104 in this guardrail assembly 1 is the same as that of the traffic guardrail structure commonly used in the market. Therefore, it will not be described in detail here.

[0042] When the base 101 is fixed to the road surface using the detachable fixing component 2, the operating principle is as follows:

[0043] First, according to the installation position of the base 101, drill mounting holes on the road surface corresponding to the T-shaped fixing holes 105. Then, place the base 101 on the road surface and align the T-shaped fixing holes 105 with the mounting holes one by one.

[0044] Next, the detachable fixing component 2 is taken out, and the T-shaped telescopic cylinder 204 is pushed down relative to the T-shaped fixing post 203 by manual pushing. The downward movement of the T-shaped telescopic cylinder 204 causes multiple tilting blocks 205 to flip and retract upward, so that the top distribution trajectory of the multiple tilting blocks 205 is smaller than the inner diameter of the mounting hole.

[0045] Then, align the bottom of the fixed cylinder 202 with the T-shaped fixing hole 105 and insert it through the mounting hole. Finally, the top circular part of the T-shaped plug-in cylinder 201 fits against the bottom of the large-diameter groove of the T-shaped fixing hole 105. At this time, release the downward pressure on the T-shaped telescopic cylinder 204. The T-shaped telescopic cylinder 204 moves upward under the elastic force of the elastic force 206. Multiple inclined blocks 205 move upward simultaneously. At the same time, the upper edge of the inner wall of the through-hole 207 squeezes and limits the inclined blocks 205, causing multiple inclined blocks 205 to flip outward simultaneously. This expands the top distribution diameter of multiple inclined blocks 205, and finally, the top corners of multiple inclined blocks 205 contact the inner wall of the mounting hole.

[0046] At this point, the installation of the detachable fixing component 2 is completed, and the base 101 is fixed. When the base 101 is subjected to an external force that pulls the detachable fixing component 2 upward, the multiple tilting blocks 205 will tend to flip outward under this pulling force, thus further pressing the multiple tilting blocks 205 against the inner wall of the mounting hole, thereby playing the role of upward movement limit, and thus keeping the base 101 stable.

[0047] If the position of guardrail component 1 needs to be adjusted, simply press the T-shaped telescopic cylinder 204 downwards to cause multiple tilting blocks 205 to flip and retract, thereby releasing the restriction on the inner wall of the mounting hole. Then pull the T-shaped fixing post 203 to remove the entire detachable fixing component 2. Compared with the traditional expansion bolt structure, it is not only more convenient to disassemble and assemble, but also prevents any parts from remaining inside the road surface layer, eliminating the need to cut the protruding part of the screw and further improving the adjustment efficiency of guardrail component 1.

[0048] Please refer to this carefully. Figures 2-5 The outer diameter of the top circular part of the T-shaped fixing column 203, the T-shaped telescopic cylinder 204, and the T-shaped plug-in cylinder 201 increases sequentially, and the bottom of the top circular part of the T-shaped fixing column 203 has an arc surface structure.

[0049] In this embodiment: when disassembling and assembling the detachable fixing component 2, disassembly and assembly tools can also be used to assist the operation (such as...). Figure 5 By hooking the disassembly and assembly tool in the middle area between the top circular part of the T-shaped fixed column 203 and the top circular part of the T-shaped telescopic cylinder 204, not only can the T-shaped telescopic cylinder 204 be pressed downward, but it is also convenient to apply tension to the T-shaped fixed column 203. The arc-shaped structure of the top circular part of the T-shaped fixed column 203 facilitates the hooking operation of the disassembly and assembly tool.

[0050] Please refer to this carefully. Figures 1-4 The outer diameter of the top circular part of the T-shaped plug tube 201 matches the diameter of the large diameter groove of the T-shaped fixing hole 105, and the outer diameter of the vertical part of the T-shaped plug tube 201 matches the diameter of the small diameter groove and the inner diameter of the mounting hole of the T-shaped fixing hole 105.

[0051] The outer diameter of the fixed cylinder 202 is smaller than the inner diameter of the mounting hole, and the outer diameter of the top distribution of the multiple tilting blocks 205 in the fully unfolded state is larger than the inner diameter of the mounting hole.

[0052] In this embodiment: by matching the outer diameter of the vertical part of the T-shaped plug tube 201 with the diameter of the small diameter groove of the T-shaped fixing hole 105 and the inner diameter of the mounting hole, the T-shaped plug tube 201 will not wobble horizontally after being inserted into the mounting hole, thus providing a horizontal limit for the mounting base 101. The top circular part of the T-shaped plug tube 201 presses against the large diameter groove of the T-shaped fixing hole 105, and together with the one-way locking of the inclined card opening 205 and the mounting hole, it can provide a vertical limit for the mounting base 101, thereby ensuring the stable position of the mounting base 101.

[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
