Description

Technical Field

[0001] This utility model belongs to the field of construction guardrail technology, specifically relating to a guardrail structure for municipal engineering construction. Background Technology

[0002] Road administration and municipal construction are important components of urban construction and development, involving multiple aspects such as roads, bridges, drainage, lighting, and greening. During construction, it is necessary not only to ensure the quality and progress of the project, but also to take into account traffic safety, environmental protection, and the impact on citizens' lives. During municipal construction, workers need to use guardrails to enclose the construction area to prevent outsiders from accidentally entering and causing safety hazards. However, some existing construction guardrails often have certain shortcomings in use, so they need to be improved.

[0003] Chinese patent CN219344283U discloses a temporary guardrail structure for municipal engineering construction, relating to the field of municipal engineering technology. The structure includes a base plate with a rotating mechanism on top. The rotating mechanism comprises two connecting columns, each with a set of insert columns fixedly connected to its lower end. The end of each insert column furthest from the connecting column is mounted on the inner wall of the base plate. A set of slots is provided on the opposite sides of the two connecting columns. An adjustment mechanism is provided on the right side of each connecting column, and each adjustment mechanism includes a first sliding rod. Through the coordinated arrangement of the base plate, insert columns, rotating mechanism, and adjustment mechanism, the device can be disassembled into multiple components, facilitating the movement of these components and providing convenience for users. Furthermore, the angle and width of the device can be adjusted as needed, greatly improving its practicality.

[0004] However, although the above-mentioned technical solution can achieve the purpose of fencing off the construction area and facilitating quick dismantling, it is divided into two parts after dismantling, and workers still need to carry them one by one. Especially when there are many guardrails, workers need to dismantle and carry them one by one, which is quite laborious and increases the workload of workers. Therefore, it has certain limitations in use. Utility Model Content

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.

[0023] Example 1:

[0024] Please see Figure 1 , Figure 2 and Figure 5As shown, a guardrail structure for municipal engineering construction includes a base 1, a connecting frame 2 fixedly connected to the top of the base 1, two adjustable guardrails 3 rotatably arranged inside the connecting frame 2, fixed sleeves 4 fixedly connected to both sides of the top of the connecting frame 2, a pull rod 5 slidingly passing through the inside of the fixed sleeve 4, a compression block 6 fixedly connected to the bottom end of the surface of the pull rod 5, a first compression spring 7 fixedly connected to the top of the compression block 6, and the top end of the first compression spring 7 fixedly connected to the inner top wall of the fixed sleeve 4, a connecting sleeve 12 fixedly connected to the middle of one side of the base 1, a second compression spring 13 fixedly connected to the inner side wall of the connecting sleeve 12, a plug pipe 14 fixedly connected to the middle of the other side of the base 1, a connecting ring 15 rotatably arranged on the surface of the plug pipe 14, a compression disc 16 fixedly connected to one end of the plug pipe 14, and the surface of the compression disc 16 penetrating the interior of the connecting sleeve 12. The connecting frame 2 allows the adjustable guardrail 3 to be rotatably connected to it. It should be noted that the bottom of the adjustable guardrail 3 is rotatably connected to the connecting frame 2 via a pivot. The adjusting guardrail 3 allows the overall guardrail angle to be adjusted. The fixed sleeve 4 allows the pull rod 5 to slide and pass through it. The pull rod 5 allows the pressing block 6 to move upward, thereby pressing the first compression spring 7. The connecting sleeve 12 allows the second compression spring 13 to be fixed to its inner wall. The insertion pipe 14 allows the connecting ring 15 to be rotatably set on its surface. The pressing plate 16 allows the second compression spring 13 to be pressed when two adjacent bases 1 are connected. Then, by rotating the connecting ring 15, it can be connected to the connecting sleeve 12. The surface of the connecting sleeve 12 is threaded, and the connecting ring 15 is threadedly connected to the surface of the connecting sleeve 12.

[0025] Example 2:

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, a retaining plate 8 is fixedly connected to the bottom of the pull rod 5, and several abutment blocks 9 are fixedly connected to the bottom of the retaining plate 8. The retaining plate 8 is used to fix the abutment blocks 9 to its bottom.

[0027] The top of the adjustable guardrail 3 has a connecting hole 10, and a snap-fit ​​sleeve 11 is fixedly connected to the inner wall of the connecting hole 10. The top of the snap-fit ​​sleeve 11 has several abutment grooves, and the surface of the abutment block 9 penetrates the interior of the abutment grooves. The snap-fit ​​sleeve 11 allows the abutment grooves to be opened, thereby allowing the abutment block 9 to be inserted into the interior of the abutment groove. Pulling the pull rod 5 upward causes the abutment block 9 to disengage from the interior of the abutment groove, thereby causing the adjustable guardrail 3 to rotate at a certain angle. Then, releasing the pull rod 5 fixes the adjustable guardrail 3.

[0028] The top and bottom of the adjustable guardrail 3 are each equipped with a first reflective strip 17, and the top and bottom of the connecting frame 2 are each equipped with a second reflective strip 18. The first reflective strip 17 and the second reflective strip 18 provide a certain level of warning effect when the entire device is used at night.

[0029] A handle 19 is fixedly connected to the center of the top of the connecting frame 2, and fixing holes are provided on both sides of the top of the base 1. The handle 19 allows the adjustable guardrail 3 to be lifted after folding, making it easy for staff to move.

[0030] The working principle of this utility model is as follows: The worker first places the adjusting guardrail 3 in the construction area, then rotates the adjusting guardrail 3 while simultaneously pulling the pull rod 5 upwards. This causes the locking plate 8 at the bottom of the pull rod 5 to move the contact block 9 upwards, disengaging it from the contact groove. At the same time, the first compression spring 7 is compressed. The worker then rotates the adjusting guardrail 3 to keep the two adjusting guardrails 3 parallel. The worker can then release the pull rod 5, at which point the first compression spring 7 returns to its original position, allowing the contact block 9 to insert into the contact groove. The adjusting guardrail 3 is then fixed, and construction can proceed. When the device is not in use, the pull rod 5 is pulled back. Pulling the lever 5 causes the locking plate 8 to move upward, and at the same time, the contact block 9 disengages from the contact groove again. Then, the worker can rotate and adjust the guardrail 3 to fold it. The worker then connects two adjacent bases 1, inserting the insertion pipe 14 on the other side of one base 1 into the connecting sleeve 12 on the other side of the other base 1, and pressing it down. At this time, the second compression spring 13 is compressed. The worker then rotates the connecting ring 15 to connect it with the connecting sleeve 12. At this time, two adjacent bases 1 are connected. The worker can also connect multiple bases 1 and then lift them together onto the transfer vehicle for centralized transfer, which is more convenient.
