Description

Technical Field

[0001] This utility model belongs to the field of road auxiliary equipment technology, specifically relating to a high-strength stainless steel guardrail post cap for highways. Background Technology

[0002] Currently, my country's expressway construction has achieved rapid development, with the total mileage of expressways reaching a record 177,000 kilometers. The leapfrog development of expressways has put forward increasingly higher requirements for related supporting facilities. Among them, the expressway guardrails that are now widely used are steel plates with (zinc or aluminum) coatings. Due to the thin and poor density of the hot-dip coating, electrochemical corrosion and coating peeling will seriously affect the surface appearance and service life.

[0003] In recent years, high-strength stainless steel guardrails have been used on highways. They have attracted widespread attention due to their outstanding advantages such as low life-cycle cost, good self-corrosion resistance, and long service life. Without post caps, the interior of high-strength stainless steel guardrail posts are easily affected by the external environment, causing corrosion.

[0004] Therefore, there is an urgent need for a post cap that can be matched with the high-strength stainless steel guardrail posts of highways. Utility Model Content

[0005] This utility model overcomes the shortcomings of the prior art and proposes a column cap for a high-strength stainless steel guardrail post on highways; solving the problem of the current lack of a column cap that matches the high-strength stainless steel guardrail post on highways.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0007] A high-strength stainless steel guardrail post cap for highways includes a post body and a post cap body. The post cap body is located at the upper end of the post body. A hook is fixedly installed on the top surface inside the post cap body. A first bolt is screwed onto the post body. A blocking post is fixedly installed at the end of the first bolt and inserted into the hook. A connecting frame is slidably sleeved on the outside of the post body. An installation plate is fixedly installed on the connecting frame. A second bolt is screwed onto the connecting frame. The end of the second bolt abuts against the outer surface of the post body.

[0008] Furthermore, a fixing plate is fixedly installed at the lower end of the column body, and the fixing plate is fixedly connected to the installation foundation by four expansion bolts; a reinforcing plate is fixedly installed between the lower end of the outer side of the column body and the fixing plate.

[0009] Furthermore, the column cap body includes a top plate, an outer limiting frame, an inner limiting frame, and a rubber pad; the outer limiting frame is sleeved on the outside of the inner limiting frame, and the same top plate is fixedly installed at the upper ends of the outer limiting frame and the inner limiting frame, and a ring of rubber pads is fixedly installed on the lower end surface of the top plate between the outer limiting frame and the inner limiting frame; the hook is fixedly installed at the center of the lower end surface of the top plate, and the hook extends downward to below the lower openings of the outer limiting frame and the inner limiting frame.

[0010] Furthermore, a reflective strip is fixedly installed on each of the four outer sides of the top plate.

[0011] Furthermore, the upper opening of the column body is inserted between the outer limiting frame and the inner limiting frame, and the upper end of the column body is in contact with the rubber pad.

[0012] Furthermore, two mounting seats are provided at a height on the end face of the mounting plate on the side away from the column body, and threaded holes are provided on the end face of the mounting seats.

[0013] Furthermore, a square fixing box is fixedly installed on the outer side of the outer limiting frame. Two guide holes are provided on the side wall of the fixing box facing the outer limiting frame, and two through holes are provided on the side wall of the outer limiting frame. The two through holes on the outer limiting frame correspond to the two guide holes on the fixing box.

[0014] Furthermore, a guide shaft is fixedly installed in the middle of the inner side of the fixed box, and a sliding plate is slidably sleeved on the outer side of the guide shaft. Two limiting blocks are fixedly installed on the side end face of the sliding plate near the outer limiting frame. The two limiting blocks extend into the inner side of the outer limiting frame through two guide holes and two through holes respectively.

[0015] Furthermore, a drive spring is installed inside the fixing box. The drive spring is located on the side of the sliding plate away from the outer limit frame. One end of the drive spring is fixedly connected to the sliding plate, and the other end of the drive spring is fixedly connected to the inner wall of the fixing box.

[0016] The beneficial effects of this utility model compared to the prior art are as follows: (1) By setting up components such as hooks and blocking posts, the hooks are welded to the lower surface of the column cap body, and the conical blocking posts are fixed inside the column body by bolt No. 1. When the conical blocking posts are inserted into the hooks, a two-way locking structure is formed to prevent the column cap body from falling off due to wind or vibration. The conical design facilitates alignment and installation, while allowing slight deformation to absorb impact energy. The frame-shaped rubber pad is used to fill the cavity between the inner limit frame and the outer limit frame to buffer vibration noise. The sealed interface prevents rainwater from seeping into the column body. Through mechanical linkage and precise matching of material properties, the column's safety, durability and ease of maintenance are comprehensively improved.

[0017] (2) By setting up components such as connecting frames, the column body can guide the connecting frames to the upper and lower limits, making it easy to adjust the usage position of the two sets of mounting seats on the front of the mounting plate according to usage requirements. The No. 2 bolt with the internal thread of the connecting frame is spirally rotated to squeeze the column body, which can position the usage position of the mounting plate. The mounting seat is used to provide threaded connection space for the bolts that penetrate the guardrail, making it easy to flexibly adjust the usage height of the guardrail later.

[0020] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, this utility model will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it. The technical solution of this utility model will be described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0021] like Figure 1As shown in Figure 6, this utility model provides a high-strength stainless steel guardrail post cap for highways, including a post body 1 and a post cap body 4. The post cap body 4 is located at the upper end of the post body 1. A hook 8 is fixedly installed on the inner top surface of the post cap body 4. A first bolt 9 is screwed onto the post body 1. A blocking post 10 is fixedly installed at the end of the first bolt 9. The blocking post 10 has a conical column structure and is inserted into the hook 8. A connecting frame 11 is slidably sleeved on the outside of the post body 1. The post body 1 can guide the connecting frame 11 to the upper and lower limits. An mounting plate 13 is fixedly installed on the connecting frame 11. A second bolt 12 is screwed onto the connecting frame 11. The end of the second bolt 12 abuts against the outer surface of the post body 1.

[0022] The column body 1 is a square cylindrical structure with an open top. A horizontal square fixing plate is fixedly installed at the lower end of the column body 1. The fixing plate is fixedly connected to the installation foundation by four expansion bolts 3. A reinforcing plate 2 is fixedly installed between the lower end of the outer side of the column body 1 and the fixing plate. The reinforcing plate 2 is a vertically installed right-angled trapezoidal plate structure.

[0023] The column cap body 4 includes a top plate, an outer limiting frame 6, an inner limiting frame 5, and a rubber pad 7. Both the outer limiting frame 6 and the inner limiting frame 5 are vertically arranged square cylindrical structures, with openings at both the top and bottom. The outer limiting frame 6 is fitted over the outer side of the inner limiting frame 5, and the axis of the outer limiting frame 6 coincides with the axis of the inner limiting frame 5. A single top plate is fixedly installed at the upper end of both the outer limiting frame 6 and the inner limiting frame 5, closing the upper openings of both. A ring of rubber pads 7 is fixedly installed on the lower surface of the top plate between the outer limiting frame 6 and the inner limiting frame 5. A reflective strip 15 is fixedly installed on the outer surfaces of the top plate, serving a warning function. A hook 8 is fixedly installed at the center of the lower surface of the top plate, extending downwards to below the lower openings of the outer limiting frame 6 and the inner limiting frame 5.

[0024] The column body 1 is the main component of the high-strength stainless steel guardrail column for highways. The right-angled trapezoidal reinforcing plate 2 is welded to the outside of the column body 1. The four sets of expansion bolts 3 on the fixing plate of the column body 1 are used to anchor the foundation and enhance the bending resistance of the column body 1 (especially to cope with side impacts). The expansion bolts 3 disperse stress and prevent the column body 1 from tilting.

[0025] The upper opening of the column body 1 is inserted between the outer limiting frame 6 and the inner limiting frame 5, and the upper end of the column body 1 is in contact with the rubber pad 7. The outer limiting frame 6 is located outside the upper opening of the column body 1, and the inner limiting frame 5 is located inside the upper opening of the column body 1, forming a nested limiting mechanism to accurately position the column cap body 4, limit horizontal displacement, and avoid sealing failure caused by installation misalignment. The rubber pad 7 is set in the cavity between the inner limiting frame 5 and the outer limiting frame 6. The rubber pad 7 is used to fill the cavity between the inner limiting frame 5 and the outer limiting frame 6, buffer vibration and noise, and seal the interface to prevent rainwater from seeping into the interior of the column body 1. The rubber pad 7 can be made of recycled butyl rubber to enhance sustainability.

[0026] The connecting frame 11 is a horizontally arranged square ring structure, and the mounting plate 13 is a vertically arranged square plate structure. The mounting plate 13 contacts the outer side of the column body 1. Two mounting seats 14 are provided at a certain height on the end face of the mounting plate 13 away from the column body 1. Threaded holes are provided on the end face of the mounting seats 14, providing threaded connection space for bolts passing through the guardrail. When the second bolt 12 is loosened, the connecting frame 11 can slide up and down on the outside of the column body 1, thereby adjusting the height of the mounting plate 13 and flexibly adjusting the usable height of the guardrail. When the second bolt 12 is tightened, the connecting frame 11 is fixed to the column body 1, thereby fixing the height of the mounting plate 13.

[0027] A square fixing box 16 is fixedly installed on the outer surface of the outer limiting frame 6. Two guide holes 17 are provided on the side wall of the fixing box 16 facing the outer limiting frame 6, and two through holes are provided on the side wall of the outer limiting frame 6. The two through holes on the outer limiting frame 6 correspond to the two guide holes 17 on the fixing box 16. A horizontal guide shaft 20 is fixedly installed in the middle of the inner side of the fixing box 16. The axis of the guide shaft 20 is perpendicular to the axis of the column body 1. A sliding plate 19 is slidably sleeved on the outside of the guide shaft 20. Two limiting blocks 18 are fixedly installed on the end face of the sliding plate 19 near the outer limiting frame 6. The two limiting blocks 18 extend into the outer limiting frame 6 through the two guide holes 17 and the two through holes, respectively. The outer wall of the limiting blocks 18 maintains sliding contact with the inner wall of the guide groove, and the guide groove provides stable guidance for the sliding of the limiting blocks 18. A drive spring 21 is provided inside the fixed box 16. The drive spring 21 is located on the side of the sliding plate 19 away from the outer limit frame 6. One end of the drive spring 21 is fixedly connected to the sliding plate 19, and the other end of the drive spring 21 is fixedly connected to the inner wall of the fixed box 16.

[0028] The working principle of this utility model is as follows: First, place the fixing plate at the lower end of the column body 1 on the installation foundation, and then use four expansion bolts 3 to fix the fixing plate to the installation foundation, thereby fixing the column body 1. Then, the column cap body 4 is sleeved on the upper outer side of the column body 1. The upper opening of the column body 1 is inserted between the outer limiting frame 6 and the inner limiting frame 5 of the column cap body 4, and the upper end of the column body 1 is in contact with the rubber pad 7. After the column cap body 4 is sleeved on the upper outer side of the column body 1, the two limiting blocks 18 are tightly abutted against the upper outer side of the column body 1 under the action of the drive spring 21. Since the column cap body 4 is not yet fixed at this time, the abutting force of the limiting blocks 18 can ensure that the column cap body 4 will not fall off accidentally. At this point, hook 8 is inserted into the inside of column body 1. Then, the blocking post 10 is inserted into the threaded hole on column body 1, and bolt 9 is screwed onto column body 1, so that the blocking post 10 is inserted into hook 8, limiting hook 8 and forming a two-way locking structure to prevent column cap body 4 from falling off due to wind or vibration. The conical design facilitates alignment during installation and allows slight deformation to absorb impact energy. Then, slide the connecting frame 11 up and down to adjust the height of mounting plate 13. After adjustment, tighten bolt 12.
