Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to an edge guardrail structure for a construction project. Background Art

[0002] During construction, in order to ensure construction safety and warn and protect pedestrians, edge guardrails are often needed. However, existing guardrails are mostly fixed structures and need to be fixedly installed on the ground when used.

[0003] For example, the application number is "202321563365.6", which discloses "a construction project edge guardrail structure". The guardrail structure needs to be fixed on the ground when in use. It is troublesome for construction workers to move and disassemble it later, and the guardrail with a fixed structure is not convenient to adjust and store. The guardrail mechanism can be moved to a designated location by setting a sliding wheel, and the extended guardrail slides in the guardrail, and one end of the pull rod can be pulled to drive the sliding block to move up. When the extended guardrail is slid to the top of one side of the limiting groove, and the sliding block is engaged in the snap-in groove by loosening the pull rod, the construction workers can extend and retract the extended guardrail, which saves storage space and makes it convenient for construction workers to adjust the length of the guardrail.

[0004] The guardrail structure increases its length by moving an extended baffle, which is stored in the guardrail when not in use. However, due to the size limitation of the guardrail itself, the size of the extended baffle is also limited, which limits the length of the guardrail structure. At the same time, after the device is stored, its length-to-width ratio is large, which is not convenient for transportation. Therefore, a construction project edge guardrail structure is proposed.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1 - Figure 4As shown, the utility model provides a technical solution: a construction engineering edge guardrail structure, including a base frame 1, a first guardrail plate 2 is fixedly connected to the top of the base frame 1, a second guardrail plate 3 is rotatably connected to one side of the first guardrail plate 2, a third guardrail plate 7 is rotatably connected to one side of the second guardrail plate 3, a first connecting component 4 is installed between the first guardrail plate 2 and the second guardrail plate 3, and a second connecting component 5 is installed between the second guardrail plate 3 and the third guardrail plate 7;

[0023] The No. 1 connecting component 4 includes a No. 1 limiting frame 401, which is fixedly installed on the No. 1 guardrail plate 2, and a No. 2 limiting frame 402 is fixedly installed on the No. 2 guardrail plate 3. The inner wall of the No. 1 limiting frame 401 is fixedly connected to a No. 1 spring 403, one end of the No. 1 spring 403 is fixedly connected to a limiting member 404, the outer wall of the limiting member 404 and the inner wall of the No. 1 limiting frame 401 are slidably connected, one end of the No. 2 limiting frame 402 is fixedly connected to a fixing member 405, the inner wall of the limiting member 404 is movably connected to a connecting rod 406, and one side of the No. 1 guardrail plate 2 is fixedly connected to a hook 407.

[0024] The No. 2 connection component 5 includes a No. 3 limiting frame 501, which is fixedly mounted on the No. 3 guardrail plate 7. The inner wall of the No. 3 limiting frame 501 is slidably connected with a limiting rod 502. The No. 3 limiting frame 501 is installed with a limiting screw 503, and the limiting rod 502 is provided with a limiting groove for contacting the limiting screw 503.

[0025] The bottom end of the base frame 1 is fixedly connected with a universal wheel, and the bottom end of the base frame 1 is installed with a support leg assembly 6.

[0026] The support leg assembly 6 includes a cylinder 601 , which is fixedly mounted on the base frame 1 , and a limiting leg 603 is slidably connected to the inner wall of the cylinder 601 , and a limiting rod 602 for limiting the movement of the limiting leg 603 is mounted on the limiting leg 603 .

[0027] A slide groove is provided on the inner wall of the second limiting frame 402 , and a guide rail is fixedly connected to the outer wall of the limiting rod 502 .

[0028] A movable hole is provided on the first limiting frame 401 , and the top end of the connecting rod 406 passes through the first limiting frame 401 through the movable hole.

[0029] When in use, first fix the position of one of the support leg assemblies 6 so that the limiting foot 603 is inserted into the ground, and then the limiting insertion rod 602 is installed to fix the position between the limiting foot 603 and the cylinder 601, and then the guardrail structure is unfolded.

[0030] During the unfolding process, the angle between the No. 1 guardrail plate 2 and the No. 2 guardrail plate 3 changes, the No. 2 limiting frame 402 and the fixing part 405 rotate, the fixing part 405 contacts the limiting part 404 during the rotation, the limiting part 404 contacts the fixing part 405, the fixing part 405 applies an extrusion force to the limiting part 404, so that the limiting part 404 moves, and the No. 1 spring 403 contracts. Due to the structural design between the limiting part 404 and the fixing part 405, the fixing part 405 will separate from the limiting part 404 during the continued rotation, but under the action of the No. 1 spring 403, the limiting part 404 is still in contact with the fixing part 405 at this time, and the limiting part 404 applies a force to the fixing part 405, and the position between the No. 1 guardrail plate 2 and the No. 2 guardrail plate 3 is fixed.

[0031] Move the limiting rod 502 so that the outer wall of the limiting rod 502 contacts the inner wall of the No. 2 limiting frame 402. At this time, the sliding connection between the limiting rod 502 and the No. 2 limiting frame 402 is achieved through the guide rail and the slide groove. At this time, the position of the limiting rod 502 and the No. 3 limiting frame 501 is fixed by the limiting screw 503, thereby fixing the position of the No. 2 guardrail board 3 and the No. 3 guardrail board 7. In order to increase the length of a single guardrail structure, the corresponding number of guardrail boards and connecting components can be added to the guardrail boards. In addition, the combination of the guardrail boards and connecting components needs to be staggered in height to avoid mutual influence.

[0032] When folding it, move the connecting rod 406, the connecting rod 406 moves, so that the limiting member 404 moves, the No. 1 spring 403 is compressed, the connecting rod 406 and the hook 407 contact, so that the No. 1 spring 403 is in a compressed state, at this time, the position fixing relationship between the No. 1 guardrail plate 2 and the No. 2 guardrail plate 3 is released, remove the limiting screw 503, so that the limiting rod 502 moves, the limiting rod 502 and the No. 2 limiting frame 402 are separated, and the position fixing relationship between the No. 2 guardrail plate 3 and the No. 3 guardrail plate 7 is released, and the No. 1 guardrail plate 2, the No. 2 guardrail plate 3 and the No. 3 guardrail plate 7 can be folded, and after folding, it is easy to store and move.

[0033] The folding guardrail panels are used to realize storage and unfolding. The guardrail panels are fixed in position by connecting components. The No. 1 connecting component 4 is used by rotating the No. 1 guardrail panel 2 and the No. 2 guardrail panel 3 to complete the position fixation between the No. 1 guardrail panel 2 and the No. 2 guardrail panel 3. The No. 2 guardrail panel 3 and the No. 3 guardrail panel 7 are fixed in position by using the moving limiting rod 502 and the No. 2 connecting component 5. By adding guardrail panels and the number of corresponding connecting components, the length of the guardrail structure can be increased, the length limitation of the guardrail structure is reduced, and when stored, it is easy to carry because it is folded and stored; through the No. 1 connecting component 4 When unfolded, the guardrail plate No. 1 2 and the guardrail plate No. 2 3 rotate, and the fixing member 405 rotates and contacts the limiting member 404, so that the limiting member 404 fixes the position of the fixing member 405 under the action of the No. 1 spring 403, thereby fixing the position between the No. 1 guardrail plate 2 and the No. 2 guardrail plate 3. When the contact position is fixed, the limiting member 404 is moved by the connecting rod 406, and the connecting rod 406 is further restricted by the hook 407. At this time, the position fixation between the No. 1 guardrail plate 2 and the No. 2 guardrail plate 3 is released, and the connection operation of the No. 1 connecting component 4 and the operation of releasing the position fixation are simple, which improves the convenience of the guardrail structure.
