Description

Technical Field

[0001] This utility model relates to the field of crash barrier technology, and in particular to a temporary crash barrier for elevated construction. Background Technology

[0002] Temporary crash barriers are made of iron pipes, processed through a series of steps including seamless pipe bending, welding, grinding and polishing, high-pressure baking paint, and film application; they are generally widely used for isolation and warning at construction sites.

[0003] Currently, most existing temporary crash barriers are single-panel structures. While single-panel barriers are easy to disassemble and install, they have poor crash protection performance and can only serve as a warning, failing to guarantee the personal safety of construction workers. Furthermore, single-panel crash barriers are generally fixed with bolts, making it difficult to flexibly adjust their position.

[0004] Therefore, it is necessary to provide a new type of temporary crash barrier for elevated construction to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a temporary anti-collision guardrail for elevated construction that is easy to install, has strong anti-collision performance, and is easy to adjust in position flexibly.

[0006] To solve the above-mentioned technical problems, the temporary anti-collision guardrail for elevated construction provided by this utility model includes: a base plate, which is welded and fixed to the bottom surface of a support pipe; a connecting piece is rotatably connected to one end of the support pipe; a collar is fixed to the other end of the support pipe; the support pipe is rotatably connected to the side wall of the base pole through this collar; one end of the support pipe is rotatably connected through the connecting piece; and a limiting block is fixed inside the connection node between the support pipe and the connecting piece; a limiting structure is fixed inside the openings at both ends of the base pole. The limiting structure includes a limiting member, a limiting groove, and a polygonal slot. The limiting groove is located in the center of the limiting member, and the polygonal slot is located at the rightmost end of the limiting member. A hub is mounted on both ends of the base rod via the limiting member. The hub includes a roller, a limiting plate, a polygonal pin, and a spring. The polygonal pin is fixed to the side wall of the top of the roller. A limiting plate is provided on the side wall of the polygonal pin, and the spring is fixed inside the limiting plate, with the spring sleeved on the side wall of the hexagonal pin.

[0007] Preferably, the length of the limiting groove is greater than the length of the polygonal slot, and the limiting plate is rotatably connected inside the limiting groove, and the spring is supported between the limiting groove and the limiting plate.

[0008] Preferably, the length of the polygonal locking post is greater than the length of the internal channel of the limiting member, and the polygonal locking post at the left end of the limiting plate is cylindrical, while the polygonal locking post at the right end of the limiting plate is engaged inside the polygonal locking groove.

[0009] Preferably, the wheel hub is engaged with the corner of the bottom of the triangular guardrail by the limiting member, and the triangular guardrail includes a top rod, a support rod and a positioning groove. The bottom end of the support rod is welded and fixed to the side wall of the bottom rod, the top rod is rotatably connected to the top end of the support rod, and the positioning grooves are respectively provided on the side wall of the top rod and the side wall of the bottom rod.

[0010] Preferably, the width of the positioning groove provided on the bottom rod is smaller than the width of the positioning groove provided on the side wall of the top rod, and the top end of the support rod is also fixed with a collar, and one end of the support tube and the support rod are both sleeved on the side wall of the positioning groove by a fixed ring.

[0011] Preferably, the two base rods are supported and limited by the support tube, and the two support rods and the support structure are combined to form an equilateral triangle.

[0012] Preferably, the diameter of the support tube is the same as the diameter of the base rod, the bottom surface of the base plate is relatively rough, and the base plate rests against the ground when there is no wheel hub support.

[0013] Compared with related technologies, the temporary anti-collision guardrail for elevated construction provided by this utility model has the following beneficial effects:

[0014] This utility model provides a temporary anti-collision guardrail for elevated construction. First, the triangular guardrail is unfolded, with both ends of the supporting structure rotating along the sidewalls of the base pole. Simultaneously, the center of the supporting structure unfolds, and the supporting structure supports the bottom ends of the triangular guardrail, forming an equilateral triangle. Then, by rotating the connecting piece in the supporting structure 90 degrees, its sidewall-fixed stop abuts against the limiting block, restricting the rotation angle of the connecting piece. This prevents the supporting structure from folding under stress, thus ensuring the stable support of the triangular guardrail. The wheel hub provides support and allows for flexible position adjustment of the triangular guardrail. By pulling the wheel hub outward to disengage it from the limiting structure, the wheel hub can be rotated, changing its angle. This causes the wheel hub to no longer support the triangular guardrail, and the base plate then contacts the ground. The friction surface on the bottom of the base plate increases the contact area between the triangular guardrail and the ground, thereby enhancing the stability of the triangular guardrail and increasing its resistance to impact. This guardrail has the advantages of easy installation, strong anti-collision performance, and flexible position adjustment. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-6 ,in Figure 1 A schematic diagram of a preferred embodiment of the temporary anti-collision guardrail for elevated construction provided by this utility model; Figure 2 for Figure 1 The diagram shows a three-dimensional representation of the triangular guardrail. Figure 3 for Figure 1 A three-dimensional structural diagram of the supporting structure shown. Figure 4 for Figure 3 A schematic diagram of the cross-section of the supporting structure shown; Figure 5 for Figure 1 The diagram shows a cross-sectional view of the hub connection node. Figure 6 for Figure 1The diagram shows a structural schematic of the limiting section of the connecting piece; the temporary anti-collision guardrail for elevated construction includes: a base plate 1, which is welded and fixed to the bottom surface of a support pipe 21. One end of the support pipe 21 is rotatably connected to a connecting piece 22, and the other end of the support pipe 21 is fixed with a collar. The support pipe 21 is rotatably connected to the side wall of the base rod 33 through this collar, and one end of the support pipe 21 is rotatably connected through the connecting piece 22. A limiting block 23 is fixed inside the connection node between the support pipe 21 and the connecting piece 22; a limiting structure 5, which is fixed inside the openings at both ends of the base rod 33. The limiting structure 5 includes... The system includes a limiting member 51, a limiting slide groove 52, and a polygonal slot 53. The limiting slide groove 52 is located in the center of the limiting member 51, and the polygonal slot 53 is located at the rightmost end of the limiting member 51. A hub 4 is mounted on both ends of the base rod 33 via the limiting member 51. The hub 4 includes a roller 41, a limiting plate 42, a polygonal locking post 43, and a spring 44. The polygonal locking post 43 is fixed to the side wall of the top of the roller 41. The limiting plate 42 is provided on the side wall of the polygonal locking post 43, and the spring 44 is fixed to the inner side of the limiting plate 42. The spring 44 is sleeved on the side wall of the hexagonal locking post.

[0024] In the specific implementation process, such as Figure 1 , Figure 2 and Figure 5 As shown, the length of the limiting groove 52 is greater than the length of the polygonal slot 53, and the limiting plate 42 is rotatably connected to the inside of the limiting groove 52, and the spring 44 is supported between the limiting groove 52 and the limiting plate 42; the length of the polygonal locking post 43 is greater than the length of the internal channel of the limiting member 51, and the polygonal locking post 43 at the left end of the limiting plate 42 is cylindrical, and the polygonal locking post 43 at the right end of the limiting plate 42 is engaged with the inside of the polygonal slot 53; the wheel hub 4 is engaged with the triangular slot 53 through the limiting member 51. At the bottom corner of the guardrail 3, the triangular guardrail 3 includes a top rod 31, a support rod 32 and a positioning groove 34. The bottom end of the support rod 32 is welded and fixed to the side wall of the bottom rod 33. The top rod 31 is rotatably connected to the top end of the support rod 32. The positioning groove 34 is respectively provided on the side wall of the top rod 31 and the side wall of the bottom rod 33. It is convenient to pull the roller 41 to make the polygonal locking post 43 disengage from the polygonal locking groove 53, so that the roller 41 can rotate, so that the roller (41) rotates out and no longer supports the bottom rod 33.

[0025] In the specific implementation process, such as Figure 1 , Figure 2 and Figure 3As shown, the width of the positioning groove 34 on the bottom rod 33 is smaller than the width of the positioning groove 34 on the side wall of the top rod 31, and the top end of the support rod 32 is also fixed with a collar. One end of the support tube 21 and the support rod 32 are both fitted onto the side wall of the positioning groove 34 by fixed rings. The two bottom rods 33 are supported and limited by the support tube 21, and the two support rods 32 and the support structure 2 are combined to form an equilateral triangle. This facilitates the rotational connection of the support rod 32 to the top rod 31 through the collar, and the support block is also rotationally connected to the bottom rod 33 through the collar, so that it can be folded by rotating the support rod 32, thereby reducing the footprint of the triangular guardrail 3.

[0026] In the specific implementation process, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the diameter of the support tube 21 is the same as the diameter of the base rod 33, and the bottom surface of the base plate 1 is relatively rough. When the base plate 1 is not supported by the wheel hub 4, it touches the ground. This allows the base plate 1, which is fixed to the bottom surface of the support tube 21, to touch the ground when the wheel hub 4 is not supported. This increases the contact area between the support tube 21 and the ground, thereby strengthening the stability of the triangular guardrail 3.

[0027] The working principle of the temporary anti-collision guardrail for elevated construction provided by this utility model is as follows:

[0028] In use, the device is first moved to the elevated construction section. Then, by pulling the bottom ends of the support rods 32 on both sides, or by pulling the bottom rods 33 on both sides, the top ends of the support rods 32 are driven to rotate on the side walls of the main rods, causing the support rods 32 and the bottom rods 33 to unfold outwards. At the same time, one end of the support tube 21 rotates on the side wall of the bottom rod 33, and the other end rotates through the connecting piece 22, thereby spreading the two sections of the support tube 21 apart and supporting them between the two bottom rods 33. Then, by rotating the connecting piece 22, its side wall fixed stop abuts against the limiting block 23, stopping the rotation of the connecting piece 22. That is, the connection node of the connecting piece 22 is in a horizontal state, thus preventing the bottom rods 33 from driving the connecting piece 22 to rotate. This restricts the position of the support pipe 21, thereby supporting and restricting the position of the base rod 33. By pushing the triangular guardrail 3, it can be moved via the hub 4, thus moving the guardrail to the construction enclosure. Then, by pulling the hub 4 outward, the polygonal locking post 43 can be driven to slide out of the polygonal locking groove 53, thereby rotating the hub 4 and causing it to no longer support the base rod 33. This causes the base plate 1, which is welded and fixed to the bottom surface of the support pipe 21, to abut against the ground, thereby increasing the contact area between the support pipe 21 and the ground, increasing the contact area between the guardrail and the ground, thereby enhancing the stability of the guardrail, and increasing the resistance when the triangular guardrail 3 is impacted. This guardrail has the advantages of easy installation, strong anti-collision performance, and easy and flexible adjustment of position.

[0029] Compared with related technologies, the temporary anti-collision guardrail for elevated construction provided by this utility model has the following beneficial effects:

[0030] This utility model provides a temporary anti-collision guardrail for elevated construction. First, the triangular guardrail 3 is unfolded. The two ends of the support structure 2 rotate along the sidewalls of the base rod 33, and the center of the support structure 2 unfolds simultaneously. The support structure 2 then supports the bottom ends of the triangular guardrail 3, supporting the triangular guardrail 3 in an equilateral triangle shape. Next, by rotating the connecting piece 22 in the support structure 2, its sidewall-fixed stop abuts against the limiting block 23 after a 90-degree rotation, limiting the rotation angle of the connecting piece 22. This prevents the support structure 2 from folding under stress, thus providing a stable support for the triangular guardrail. The base plate 1 provides support, and the hub 4 can be flexibly adjusted in position relative to the triangular guardrail 3. By pulling the hub 4 outward to disengage it from the limiting structure 5, the hub 4 can be rotated, causing its angle to change. This results in the hub 4 no longer supporting the triangular guardrail 3, and the base plate 1 then contacts the ground. The friction surface on the bottom of the base plate 1 increases the contact area between the triangular guardrail 3 and the ground, thereby enhancing the stability of the triangular guardrail 3 and increasing the resistance when impacted. This guardrail has the advantages of easy installation, strong anti-collision performance, and flexible position adjustment.
