[0022] The present invention is further described in detail below in conjunction with the embodiments:

[0023] like Figures 1 to 3 As shown, a construction site safety protection device comprises a lower protection plate 1 and an upper protection plate 2, wherein the bottom four corners of the lower protection plate 1 are provided with lifting legs, and a plurality of buffer components 6 are fixedly connected between the lower protection plate 1 and the upper protection plate 2, wherein the buffer component 6 comprises a buffer spring 602 arranged between the lower protection plate 1 and the upper protection plate 2, wherein sleeves 603 are symmetrically arranged on both sides of the buffer spring 602, wherein both sleeves 603 are fixedly connected to the bottom of the upper protection plate 2, and compression springs 605 are sleeved on the outside of the two sleeves 603, wherein one end of the compression spring 605 is fixedly connected to the bottom of the upper protection plate 2, and the other end of the compression spring 605 is fixedly connected to a collar 606, and both sides of the outside of the collar 606 are fixedly connected to force-bearing feet 607. The interior of the sleeve 603 is slidably connected to a fixed pipe 604, and one end of the fixed pipe 604 is fixedly connected to the lower protection plate 1.

[0024] Specifically, two force equalizing plates 601 are respectively connected to the two ends of the buffer spring 602, and then the two force equalizing plates 601 are respectively fixed to the upper protective plate 2 and the lower protective plate 1, so that when the upper protective plate 2 is impacted, the impact force is reduced by the buffer spring 602, and the force is dispersed by the force equalizing plate 601, and then the sleeves 603 arranged on both sides move downward, so that the force-bearing foot 607 contacts the lower protective plate 1, and the compression spring 605 is restricted by the ring 606, thereby further weakening the impact force, so that the impact force of falling objects on the upper protective plate 2 is greatly weakened, preventing the upper protective plate 2 from being easily damaged, thereby extending the service life of the device, and at the same time effectively avoiding injuries to construction personnel, ensuring the safety of construction. In addition, one end of the compression spring 605 is fixed by the upper protective plate 2, so that the compression spring 605 will not shift when moving, thereby ensuring the stability of the structure. The fixed tube 604 is fixed by the lower protective plate 1, so that the sleeve 603 will not be misplaced when moving up and down, and the two sleeves 603 are symmetrically arranged to further enhance the buffering effect, thereby ensuring the safety of construction workers.

[0025] Example 1

[0026] In this embodiment, support columns 7 are provided at the four corners between the lower protective plate 1 and the upper protective plate 2. The support columns 7 include a bottom column 701 fixedly connected to the lower protective plate 1 and a top column 702 fixedly connected to the upper protective plate 2. The top column 702 is telescopically connected to the bottom column 701.

[0027] The upper protective plate 2 is supported by the support column 7, and the multiple buffer components 6 connected between the upper protective plate 2 and the lower protective plate 1 are used to intercept falling objects from high altitudes at the construction site and reduce the impact force of the falling objects, thereby protecting the safety of construction workers.

[0028] Example 2

[0029] This embodiment specifically defines the structure of the lifting legs. The lifting legs include telescopic pillars 4 fixedly arranged at the four corners of the bottom of the lower protective plate 1, and the outsides of the four telescopic pillars 4 are sleeved with sleeve rods 3, and the bottoms of the four sleeve rods 3 are respectively provided with universal wheels. The outsides of the two sleeve rods 3 on the front side are fixedly connected to motors 5, and the output end of the motor 5 is fixedly connected to a threaded rod 8, and the outside of the threaded rod 8 is threadedly connected to a threaded block 9, and the outside of the threaded block 9 is rotatably connected to a connecting rod 10.

[0030] Specifically, multiple telescopic pillars 4 are fixed by the lower protective plate 1, and then the motor 5 fixedly connected to the outside of the two front sleeve rods 3 drives the threaded rod 8 to rotate, thereby moving the threaded block 9. Fixing the motor 5 can make the structure stable during operation and not prone to shaking. Then, the movement of the threaded block 9 drives one end of the connecting rod 10 to move, thereby raising the lower protective plate 1 and realizing the height adjustment of the protective device, so as to adapt to construction scenarios in various situations and improve the flexibility of the device.

[0031] Example 3

[0032] In this embodiment, both left and right sides of the bottom of the lower protective plate 1 are provided with a slide groove 12, and a slider 13 is slidably connected inside the slide groove 12; the outsides of the two rear sleeve rods 3 are rotatably connected with the support rod 11, and the other end of the support rod 11 is rotatably connected to the inside of the slider 13; the outside of the sleeve rod 3 is provided with an insertion rod 14, and the outside of the insertion rod 14 is slidably connected to the inside of the telescopic support 4;

[0033] Specifically, the slide 12 allows the slider 13 to always move in the same horizontal direction when moving, thereby ensuring the stability of the device operation, thereby driving one end of the support rod 11 to move, and the support rod 11 supports the lower protective plate 1, so that the lower protective plate 1 is always stable when lifting and lowering, and the structure operates stably. The insertion rod 14 can fix the height of the device after completing the height adjustment to prevent collision from causing the top height to drop, thereby improving the reliability of the device.

[0034] Example 4

[0035] In this embodiment, the outside of the lower protective plate 1 is fixedly connected with a dust suppression water pipe 15, and a plurality of atomizing nozzles are installed on the outside of the dust suppression water pipe 15. The plurality of atomizing nozzles connected to the outside of the dust suppression water pipe 15 can reduce the dust around the construction, thereby ensuring the health of the working environment of the construction workers.

[0036] Working principle: When using this protective device, first move it to the use position through the universal wheel, then start the motor 5, and drive the threaded rod 8 to rotate through the motor 5, so that the threaded block 9 starts to move along the threaded rod 8, thereby driving one end of the connecting rod 10 to rotate, and the other end of the connecting rod 10 pushes the lower protective plate 1 to move. At the same time, one end of the support rod 11 connected to the outside of the sleeve rod 3 rotates, and the other end is connected to the slider 13, so that the slider 13 slides inside the slide groove 12, thereby changing the height of the lower protective plate 1, realizing the height adjustment of the protective device, so that the height of the protective device can adapt to the work needs of the workers and is more flexible to use.

[0037] The buffering effect of falling objects from high altitude is achieved through the lower protective plate 1 and the upper protective plate 2 and the multiple buffer components 6 fixed therebetween. The support column 7 supports the upper protective plate 2. Specifically, after the upper protective plate 2 is impacted, the top column 702 is pushed downward toward the bottom column 701, and pressure is applied to the buffer spring 602, and the two sleeves 603 are pushed downward, sliding along the outside of the fixed tube 604, and the compression spring 605 outside the sleeve 603 is moved downward, pushing the collar 606 to move, and finally making the force-bearing foot 607 contact the lower protective plate 1. At this time, the compression spring 605 is forced to shrink, so that the falling objects from high altitude on the construction site are intercepted with the cooperation of multiple structures, and a certain buffering effect is achieved, which disperses the impact force generated by the collision, thereby ensuring the safety of the construction workers. And through the multiple atomizing nozzles connected to the outside of the dust suppression water pipe 15, the dust around the construction can be reduced, thereby ensuring the health of the working environment of the construction workers.
