Description

Technical Field

[0001] This utility model relates to the field of construction engineering, and in particular to a safety management device for construction site. Background Art

[0002] On construction sites, various safety management devices play a crucial role. Good safety management also helps companies reduce the cost of safety accidents and avoid economic losses caused by accident compensation, work stoppages, and rectification. On construction sites, guardrails are installed at the edges of some buildings, openings, stairwells, and other locations to isolate and protect against objects rolling down or people accidentally entering dangerous areas, and to prevent people and objects from falling. However, the fixing spikes on the base of some safety guardrails are too cumbersome to use.

[0003] A search revealed Chinese Patent Publication No. CN221372990U, which discloses a safety guardrail for construction projects. The guardrail includes a post, a reinforcing mechanism at the bottom of the post, an installation mechanism on one side of the post, and a guardrail bar on the outer surface of the installation mechanism. This invention enhances the stability of the safety guardrail through the cooperation of the post, reinforcing mechanism, base plate, first threaded hole, threaded rod, turntable, fixing seat, second threaded hole, and conical anti-slip block. This prevents the safety guardrail from swaying or tilting when installed on the periphery of a construction project due to adverse weather or external interference, thus affecting its normal use. The cooperation of the post, installation mechanism, mounting frame, spring, limit block, locking block, guardrail bar, installation groove, and locking groove makes it convenient for workers to replace a damaged guardrail bar.

[0004] Although the above-mentioned technology has some structural improvements, there are still areas for improvement in its use. When using the guardrail, the bottom conical spikes need to be inserted into the ground to improve stability. However, when disassembling the guardrail, the entire guardrail needs to be pulled upwards with force, which is too time-consuming and laborious. Furthermore, the guardrail cannot be placed when the ground is hard and cannot be damaged, which greatly reduces its practicality. Therefore, a construction site safety management device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a construction site safety management device, which aims to improve the problem that the guardrails in some existing construction site safety management devices are too cumbersome to disassemble and remove during use.

A gear is fixedly connected to the right surface of the cylinder.

[0009] As a further description of the above technical solution:

[0010] The reinforcement component also includes a ground spike, which is slidably connected to the upper surface of the front end of the support frame, and a connecting plate is fixedly connected to the left surface of the top of the ground spike.

[0012] A groove is provided at the rear end of the left surface of the connecting plate, and a rectangular strip is slidably connected to the inner wall of the groove. The right surface of the bottom end of the rotating plate is rotatably connected to the left surface of the rectangular strip.

[0013] As a further description of the above technical solution:

[0014] The connecting plate, ground spike, rectangular bar, and rotating plate are provided in multiple sets, and the multiple sets of connecting plates, ground spikes, rectangular bars, and rotating plates are symmetrically arranged with the center line of the rotating plate as the axis of symmetry.

[0015] As a further description of the above technical solution:

[0016] A spring is fixedly connected to the left surface of the moving bar, and the left end of the spring is fixedly connected to the inner wall of the push plate.

[0017] As a further description of the above technical solution:

Moreover, the whole process uses the lever principle, making the operation more labor-saving.

[0023] 2. In this utility model, the angle of the push plate can be adjusted. When the ground spikes are not needed, the gear can be released from its limiting position on the push plate, and the push plate can be pushed to be hidden between multiple sets of rubber blocks, thereby reducing the space occupied.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a construction site safety management device, including a support frame 1 to ensure the stability of a guardrail. A connecting strip 2 is provided on the left surface of the support frame 1, allowing for a stable connection between the left and right sides of the support frame 1. A reinforcing component is provided on the left surface of the bottom end of the support frame 1, with a limit component on the inner wall of the reinforcing component. The reinforcing component includes a fixing rod 35, which is fixedly connected to the left surface of the bottom end of the support frame 1. A rotating plate 34 is rotatably connected to the left surface of the fixing rod 35, with the top of the rotating plate 34... The inner wall of the connecting strip 2 is rotatably connected to a push plate 36. By pushing the push plate 36, the rotating plate 34 rotates around the center of the fixed rod 35. The ground spike 32 is lifted by lever, which is more labor-saving. The inner wall of the connecting strip 2 is fixedly connected to a rubber block 4. The rubber block 4 has a certain elasticity. When the push plate 36 is pushed into the inner wall of the connecting strip 2, it will squeeze the rubber block 4. The rubber block 4 will fix the push plate 36 by its own elasticity. The rear surface of the push plate 36 contacts the inner wall of the connecting strip 2, and the rubber block 4 contacts the right surface of the push plate 36.

[0032] Reference Figure 2 - Figure 4 The limiting component includes a moving bar 51. Pushing the moving bar 51 can cause the cylinder 53 and the gear 54 to move synchronously, and can control the position of the gear 54, improving convenience. The moving bar 51 is slidably connected to the inner wall of the push plate 36. The right surface of the bottom end of the moving bar 51 is fixedly connected to the cylinder 53 to ensure the stable movement of the gear 54. The cylinder 53 slides on the inner wall of the bottom end of the push plate 36, and the right surface of the cylinder 53 is fixedly connected to the gear 54 to limit the movement of the push plate 36.

[0033] Reference Figure 1 - Figure 3The reinforcement components also include spikes 32, which can be inserted into the ground to make the guardrail more stable. The spikes 32 are slidably connected to the upper surface of the front end of the support frame 1. A connecting plate 31 is fixedly connected to the left surface of the top of the spikes 32. When the connecting plate 31 moves, it can drive multiple sets of spikes 32 to move, ensuring the synchronicity of the movement of multiple sets of spikes 32. A groove 37 is opened at the rear end of the left surface of the connecting plate 31. A rectangular strip 33 is slidably connected to the inner wall of the groove 37. When the rotating plate 34 is rotated, the left surface of the rectangular strip 33 will contact the right surface of the bottom end of the rotating plate 34. The rectangular bar 33 rotates, and the right end of the rectangular bar 33 slides on the inner wall of the groove 37, ensuring that the spikes 32 can move smoothly up or down. The right surface of the bottom end of the rotating plate 34 is rotatably connected to the left surface of the rectangular bar 33. Multiple sets of connecting plates 31, spikes 32, rectangular bars 33, and rotating plates 34 are provided, and multiple sets of connecting plates 31, spikes 32, rectangular bars 33, and rotating plates 34 are symmetrically arranged with the center line of the rotating plate 34 as the axis of symmetry. The multiple sets of connecting plates 31, spikes 32, rectangular bars 33, and rotating plates 34 make the guardrail more stable when placed.

[0034] Reference Figure 3 - Figure 4 A spring 52 is fixedly connected to the left surface of the moving bar 51. The spring 52 pushes the push plate 36 to the right through its elasticity to ensure the stability of the gear 54's limit. The left end of the spring 52 is fixedly connected to the inner wall of the push plate 36. The limit assembly also includes a limit groove 55. The shape of the inner wall of the limit groove 55 is adapted to the gear 54 to ensure the stability of the limit and to perform multi-angle limit. The limit groove 55 is opened on the right side of the inner wall of the top of the rotating plate 34, and the right surface of the gear 54 contacts the inner wall of the limit groove 55.

[0035] Working principle: When in use, the spikes 32 are inserted into the ground to reinforce the guardrail and improve its stability. When the spikes 32 need to be removed, the push plate 36 is pulled. The push plate 36 drives the rotating plate 34 to rotate around the fixed rod 35 as the origin. At this time, the rotating plate 34 will drive the rectangular strip 33 connected at the bottom to move. The rectangular strip 33 and the rotating plate 34 will rotate. At the same time, the right end of the rectangular strip 33 will slide on the inner wall of the slide groove 37 and lift the connecting plate 31. The connecting plate 31 will drive the spikes 32 to move and detach from the ground. Afterwards, the spikes 32 need to be inserted into the ground again by pushing the push plate 36 in the opposite direction. The subsequent structural cooperation is the same as above, but the direction of movement of some structures is opposite to that above.

[0036] Additionally, when the spike 32 is not in use, the push plate 36 may be tilted, occupying a certain amount of space. This allows the moving bar 51 to move the cylinder 53 and gear 54. Simultaneously, the moving bar 51 will compress the spring 52, and the gear 54 will disengage from the inner wall of the limiting groove 55, releasing the gear 54 from its limiting position on the push plate 36. Then, the push plate 36 can be pushed to rotate between it and the rotating plate 34 until it is hidden between the multiple sets of rubber blocks 4. This reduces the space occupied by the push plate 36 and allows for adjustment of the angle of the push plate 36, making the movement of the spike 32 easier. After adjustment, the moving bar 51 can be released, and the spring 52 will use its elasticity to reset the moving bar 51, cylinder 53, and gear 54, causing the gear 54 to lock into the inner wall of the limiting groove 55, thus limiting the push plate 36.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
