Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, specifically to an assembled profile guardrail. Background Technology

[0002] Profile railings refer to railing systems that use profiles (such as square tubes, round tubes, I-beams, and channel steel) that have been extruded, rolled, or cold-bent as the main components, and are assembled by welding, bolting, or other means.

[0003] As disclosed in the patent announcement CN220869018U, an aluminum profile guardrail includes two posts. Each post has a base fixedly connected to its bottom end and a fixed housing fixedly connected to its top end. Each of the two posts has a first sliding groove on its opposite sides. A motor is housed inside the fixed housing, and a screw is fixedly connected to the output shaft of the motor. The beneficial effects of this invention are as follows: the motor drives the screw to rotate, which in turn moves the main isolation plate downwards. At this point, the secondary isolation plate inside the second sliding groove is no longer pulled by the suspension rope and slides within the second sliding groove under its own weight, thereby causing the secondary isolation plates to descend sequentially. This allows the secondary isolation plates and the main isolation plate to descend even lower, facilitating the transport of goods in emergency situations.

[0004] While the aforementioned patent facilitates the transport of items in emergency situations, the guardrail system lacks standardized connection interfaces, making it difficult to quickly assemble and expand multiple units. This limits its application in large-scale protection scenarios. Furthermore, due to the use of a motor-driven lifting mechanism, it is difficult to achieve synchronous control when multiple guardrail units are linked, which may lead to asynchronous lifting. At the same time, the built-in motor and transmission mechanism increase the complexity of the system, significantly increasing costs and maintenance difficulties when assembling multiple units.

[0025] 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.

[0026] like Figure 1-4 As shown, this utility model provides a technical solution:

[0027] An assembled profile guardrail includes two bases 1. A vertical rectangular support rod 2 is provided at the top of the base 1. A clamping block 3 is movably provided at the top of the rectangular support rod 2. A protective mechanism is detachably installed between the two rectangular support rods 2. The protective mechanism consists of a protective rod 4 and a frame 5. Several protective rods 4 are arranged sequentially from top to bottom between the two frames 5. The two ends of the protective rods 4 are welded and fixed to the frame 5. A splicing mechanism is provided at the upper and lower ends of the frame 5 and the rectangular support rod 2. The splicing mechanism includes a support block 19. The support block 19 is welded at the connection between the base 1 and the rectangular support rod 2. Positioning rods 6 are fixedly connected to both ends of the support block 19 and the clamping block 3 on the same side. Positioning sleeves 7 that are movably sleeved with the positioning rods 6 are fixedly installed at the upper and lower ends of both sides of the frame 5. The splicing mechanism also includes bolts 8. Bolts 8 are movably installed in the middle of the clamping block 3 through a bearing. A threaded groove 9 that is threadedly connected to the bolt 8 is opened at the top of the rectangular support rod 2.

[0028] In this embodiment, the standardized positioning rod 6 and positioning sleeve 7 are used to achieve rapid installation and disassembly of the guardrail unit, which significantly improves construction efficiency, facilitates the rapid assembly of multiple identical devices, and solves the problem of splicing difficulties caused by the inconsistent connection interfaces of the existing guardrail system.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, a limiting mechanism is provided in the middle of the frame 5 and the rectangular support rod 2. The limiting mechanism includes a plug rod 10. The plug rod 10 is movably installed on the inner side of both ends of the middle of the rectangular support rod 2. A column head 11 is fixedly installed at the end of the plug rod 10 near the inside of the rectangular support rod 2. A screw rod 12 is threadedly connected to the middle of the front of the rectangular support rod 2. A column head 13 is fixedly installed at the end of the screw rod 12 inside the rectangular support rod 2. A knob 14 is fixedly installed at the outer end of the screw rod 12. A fixing block 15 is fixedly installed in the middle of the opposite side of the frame 5. A slot 16 matching the plug rod 10 is opened in the middle of the fixing block 15. A retaining ring 17 is fixedly connected to the outer wall of the middle of the plug rod 10. A compression spring 18 is provided between the retaining ring 17 and the inner wall of the rectangular support rod 2.

[0030] In this embodiment, by setting a rotatable and adjustable limiting mechanism, the installation angle of the guardrail unit can be flexibly adjusted during assembly and use, which meets the installation requirements under different site conditions and enhances the applicability and practicality of the guardrail system.

[0031] Working principle: During operation, firstly, fix the two bases 1 to the ground at a preset distance. Then, connect the positioning sleeves 7 on the lower outer side of the two pole frames 5 to the two positioning rods 6 on the upper end of the support block 19. Next, place the clamping block 3 on the upper end of the rectangular support rod 2 and connect the positioning rods 6 to the positioning sleeves 7 on the upper end of the pole frame 5. Then, twist the bolt 8 so that the bolt 8 is threadedly connected to the threaded groove 9. The main function of the limiting mechanism is to ensure that all pole frames 5 are kept on the same horizontal plane through the precise cooperation of the insertion rod 10 and the slot 16 when multiple guardrail units are set up side by side. When it is necessary to adjust the angle of the pole frame 5, first rotate the knob 14 counterclockwise to retract the screw 12, and the first column head 13 and the second column head 11 separate. The compression spring 18 pushes the retaining ring 17 to make the insertion rod 10 exit from the slot 16 of the fixing block 15. At this time, the pole frame 5 can be rotated to the desired position.
