Technical Field
[0001] The present application relates to the technical field of building construction, and in particular to a road construction safety guardrail. Background Art
[0002] The construction guardrail is made of an iron pipe, which is made through layers of processing such as seamless iron pipe bending, welding, grinding and polishing, high-pressure baking paint, and film pasting. It is generally widely used for isolation and warning in construction sites.
[0003] As disclosed in Chinese Patent Publication No. (CN220908254U), a road construction safety guardrail includes an upper telescopic member and a lower telescopic member, wherein the upper telescopic member is located directly above the lower telescopic member, and a plurality of through holes are provided on a surface of the lower telescopic member facing the upper telescopic member, in which a connecting rod is inserted, and a rectangular groove is provided on the front side and the rear side of the annular surface of the connecting rod, in which a supporting member is hinged, and an adjusting member is connected and fixed to a surface of the upper telescopic member facing the lower telescopic member, and an end of the connecting rod away from the lower telescopic member is fixed in the adjusting member. The utility model facilitates adjustment of the height and length of the guardrail, and there is no need to install fixed feet on the guardrail, thereby facilitating transportation and transfer after construction is completed.
[0004] However, as in the above-mentioned patent, there is still a problem of poor connection and combination effect of road guardrails. In the prior art taking the above-mentioned patent as an example, by setting the guardrail as a combination structure that can adjust the length in multiple directions such as up, down, left, and right, it can be conveniently adjusted. However, due to the length and curvature of the road, it is necessary to connect multiple groups of guardrails and change the angle, etc., and the prior art has poor effect in terms of combination connection, which affects the stability of the guardrail. Utility Model Content
[0005] In view of the shortcomings of the prior art, the present application provides a road construction safety guardrail, which has the advantages of good connection and combination stability, and solves the problem of poor connection and combination effect of road guardrails.
[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: A road construction safety guardrail, comprising a relay pile, a connecting mechanism is provided on the outer side of the relay pile, and a fixing mechanism is provided on the inner walls of the front and rear sides of the connecting mechanism;
[0007] The connecting mechanism includes four telescopic sleeves, four limit clamps, four support springs, four guide blocks, a guardrail body and a bottom support seat. A connecting groove is opened on the outer side of the relay pile. The four telescopic sleeves are respectively fixed to the front and rear inner walls of the connecting groove. The four limit clamps are respectively fixed to the side opposite to the four telescopic sleeves. The four support springs are respectively sleeved on the outer sides of the four telescopic sleeves, and the two ends of the support springs are respectively fixed to the side opposite to the limit clamp and the inner wall of the connecting groove. The four guide blocks are respectively fixed to the right sides of the four limit clamps. The guardrail body is clamped between the opposite sides of the limit clamps on the front and rear sides, and the bottom support seat is fixed to the lower surface of the relay pile.
[0008] By adopting this technical solution, the combination of these components enables the guardrail to adapt to different installation environments and is easy to adjust and fix.
[0009] Furthermore, the shape of the limit clamp is U-shaped, and the distance between the inner walls on the upper and lower sides of the connecting groove is equal to the height of the guardrail body.
[0010] By adopting this technical solution, it is ensured that the guardrail body can be stably installed in the connecting groove, providing good vertical support.
[0011] Furthermore, the cross-sectional shape of the guide block is a triangle, and the width of the guide block is equal to the width of the limiting clamp.
[0012] By adopting this technical solution, an effective guiding effect is provided, and at the same time, its width is equal to that of the limit clamp, thereby ensuring the stability of the guardrail body during the insertion and adjustment process.
[0013] Furthermore, the upper surface of the bottom support seat is provided with four anchor holes penetrating to the bottom, and the internal threads of the anchor holes are connected with anchor rods.
[0014] By adopting this technical solution, the connection between the guardrail and the ground is strengthened, providing additional stability and fixing force, and is suitable for a variety of ground conditions.
[0015] Furthermore, the fixing mechanism includes two studs, two push plates, four sliding rods, two fixing splints and two limit nuts. The front and rear inner walls of the connecting groove are provided with fixing holes, and the two studs are respectively fixed to the inner walls of the two fixing holes. The two push plates are respectively slidably connected to the outer sides of the two studs, the four sliding rods are respectively fixed to the opposite sides of the two push plates, the two fixing splints are respectively fixed to the opposite ends of the front and rear sliding rods, and the two limit nuts are respectively threadedly connected to the outer sides of the two studs.
[0016] By adopting this technical solution, a reliable fixing mechanism is provided to ensure that the guardrail body will not loosen when subjected to external force.
[0017] Furthermore, four sliding holes are respectively formed on the inner walls on both sides of the front and rear of the connecting groove, and four sliding rods are respectively slidably connected to the inner walls of the four sliding holes.
[0018] By adopting this technical solution, the push plate and the fixed clamping plate are allowed to be fine-tuned when fixed, thereby improving the installation accuracy and stability of the guardrail.
[0019] Furthermore, the shape of the fixing clamp is U-shaped, and anti-slip pads are fixed to the inner walls of the two fixing clamps.
[0020] By adopting this technical solution, the friction between the fixing clamp and the guardrail body is increased, the sliding of the guardrail body is prevented, and the fixing effect is improved.
[0021] Furthermore, two docking plates are fixed to one side of the front fixing plate relative to the rear fixing plate, and slots corresponding to the positions of the two docking plates are provided on one side of the rear fixing plate relative to the front fixing plate.
[0022] By adopting this technical solution, precise matching between the fixed splints is allowed, providing a reliable connection method and enhancing the stability of the entire guardrail system.
[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0024] 1. The road construction safety guardrail is provided with a connecting mechanism, and the anchor rod is driven into the ground for fixed connection through a tool to provide stable bottom support for the relay pile and the guardrail. One end of the guardrail body is further inserted into the connecting groove, and the corresponding limit clamp is driven to move to both sides and compress the support spring in cooperation with the guide block. When the vertical beam at one end of the guardrail body moves to the limit clamp position, the support spring rebounds and the position of the guardrail body in the connecting groove is clamped and limited for subsequent secondary fixation, thereby improving the installation efficiency and stability of the road construction safety guardrail, and enhancing its adaptability and convenience of maintenance. At the same time, the connecting groove can be opened in different directions outside the relay pile to achieve the purpose of turning and changing direction.
[0025] 2. The road construction safety guardrail is equipped with a fixing mechanism. After the guardrail body is initially limited and connected, the push plate will move along the stud by tightening the limit nut, and then push the slide bar. The slide bar pushes the fixed splint to move and fit to the outside of the guardrail body, and transmits the force to the guardrail body to achieve secondary fixation. Among them, the anti-slip pad increases the friction between the fixed splint and the guardrail body to prevent the guardrail body from sliding. At the same time, when the two fixed splints move to one side of the guardrail body and fit together, the front fixed splint cooperates with the slot of the rear fixed splint through the docking plate to achieve a more stable connection and form an integral structure, thereby realizing secondary fixation of the guardrail body and ensuring the stability and safety of the guardrail body in the connecting groove.

DETAILED DESCRIPTION
[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0033] See also Figures 1 to 2 A road construction safety guardrail in this embodiment includes a relay pile 1, a connecting mechanism 2 is provided on the outer side of the relay pile 1, and a fixing mechanism 3 is provided on the inner walls of the front and rear sides of the connecting mechanism 2.
[0034] See also Figure 3In order to combine and connect the guardrails, the connecting mechanism 2 in this embodiment includes four telescopic sleeves 21, four limit clips 22, four support springs 23, four guide blocks 24, a guardrail body 25 and a bottom support seat 26. A connecting groove 27 is provided on the outer side of the relay pile 1. The four telescopic sleeves 21 are respectively fixed to the inner walls of the front and rear sides of the connecting groove 27. The four limit clips 22 are respectively fixed to the opposite sides of the four telescopic sleeves 21. The four support springs 23 are respectively sleeved on the outer sides of the four telescopic sleeves 21, and the support springs 23 are respectively sleeved on the outer sides of the four telescopic sleeves 21. The two ends of the spring 23 are respectively fixed to the side opposite to the inner wall of the limit clip 22 and the connecting groove 27, and the four guide blocks 24 are respectively fixed to the right sides of the four limit clips 22. One end of the guardrail body 25 is inserted into the connecting groove 27 and the guardrail body 25 is pushed inward. When the guardrail body 25 moves, it contacts the guide block 24. The guardrail body 25 is clamped between the opposite sides of the limit clips 22 on the front and rear sides. The bottom support seat 26 is fixed to the lower surface of the relay pile 1. The connecting groove 27 can be opened at different positions on the outside of the relay pile 1 to achieve the purpose of turning and changing direction.
[0035] In this embodiment, the shape of the limit clip 22 is U-shaped, and the distance between the inner walls on the upper and lower sides of the connecting groove 27 is equal to the height of the guardrail body 25. The cross-sectional shape of the guide block 24 is triangular. Due to the triangular shape, the guide block 24 has a slope on one side. As the guardrail body 25 moves, it will drive the corresponding limit clip 22 to move to both sides and compress the support spring 23. The width of the guide block 24 is equal to the width of the limit clip 22. When the vertical beam at one end of the guardrail body 25 moves to the position of the limit clip 22, the support spring 23 rebounds, thereby pushing the limit clip 22 to move and close to the guardrail body 25, and the position of the guardrail body 25 in the connecting groove 27 is clamped and limited for subsequent secondary fixation. Four anchor holes are opened on the upper surface of the bottom support seat 26 that penetrate to the bottom, and the internal threads of the anchor holes are connected with anchor rods 28. First, the relay pile 1 is placed at the specified position according to the road guardrail installation requirements, and then the anchor rod 28 is driven into the ground and fixedly connected by a tool to provide stable bottom support for the relay pile 1 and the guardrail.
[0036] See also Figures 4 to 5The two fixing plates 34 are fixed to the sides of the two fixing holes, and the fixing plates 34 are fixed to the sides of the two fixing holes.
[0037] The locking cam 36 is provided on the locking cam 36 to lock the locking cam 36. The locking cam 36 is provided on the side walls of the locking cam 36 to lock the locking cam 36.
[0038] The working principle of the above embodiment is:
[0039] (1) When the guardrail is combined and connected for use, the relay pile 1 is first placed at the designated position according to the road guardrail installation requirements, and then the anchor rod 28 is driven into the ground by a tool to fix the connection, so as to provide a stable bottom support for the relay pile 1 and the guardrail. One end of the guardrail body 25 is further inserted into the connecting groove 27, and the guardrail body 25 is pushed inward. When the guardrail body 25 moves, it contacts the guide block 24. Since the guide block 24 has a slant on one side due to its triangular shape, as the guardrail body 25 moves, it will drive the corresponding limit clip 22 to move to both sides and compress the support spring 23. When the vertical beam at one end of the guardrail body 25 moves to the position of the limit clip 22, the support spring 23 rebounds, thereby pushing the limit clip 22 to move and close to the guardrail body 25, and the position of the guardrail body 25 in the connecting groove 27 is clamped and limited, so as to be subsequently fixed for a second time. The connecting groove 27 can be opened at different directions outside the relay pile 1 to achieve the purpose of turning and changing direction.
[0040] (2) When the connected guardrail is fixed for use, after the guardrail body 25 is initially limited and connected, the push plate 32 will move along the stud 31 by tightening the limit nut 35, and then push the slide bar 33. The slide bar 33 pushes the fixed clamping plate 34 to move and fit to the outside of the guardrail body 25, and transmits the force to the guardrail body 25 to achieve secondary fixation. Among them, the anti-slip pad 36 increases the friction between the fixed clamping plate 34 and the guardrail body 25 to prevent the guardrail body 25 from sliding. At the same time, when the two fixed clamping plates 34 move to one side of the guardrail body 25 and fit together, the front fixed clamping plate 34 cooperates with the slot 38 of the rear fixed clamping plate 34 through the docking plate 37 to achieve a more stable connection and form an integral structure, thereby achieving secondary fixation of the guardrail body 25 and ensuring the stability and safety of the guardrail body 25 in the connecting groove 27.
