Description

Technical Field

[0001] This invention relates to the field of building construction technology, and more specifically to a safety protection device for building construction. Background Technology

[0002] Currently, in the construction of high-rise buildings, protective netting is usually installed on the outside of the walls to prevent falling sand and gravel from injuring workers on the ground below. Its primary function is to protect workers in case of accidental falls. The common method is to fix the protective netting to a support frame, with one side of the frame fixed to the wall and the other side extending away from the wall. However, this method has several problems: the netting alone has limited cushioning effect, and falls can easily cause injury; the outward extension of the support frame can cause injury if it collides with a falling worker; if previously fallen sand or gravel is already inside the netting, it can also injure falling workers; and falling workers often knock down other objects, which can be very dangerous if they hit someone falling into the netting from above.

[0003] Therefore, how to solve the above-mentioned technical problems has become the challenge faced by this invention. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a safety protection device with excellent protective performance for building construction.

[0005] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a safety protection device for building construction, characterized in that it includes a support frame fixedly connected to the outside of the wall, a support plate is provided on the support frame, a sponge pad is provided above the support plate, and an anti-fall net is provided above the sponge pad.

[0006] The fall protection net is movably connected to a top protective plate via a first linkage component, and the fall protection net is movably connected to a cleaning plate via a second linkage component.

[0007] The support frame includes two symmetrically arranged vertical mounting boxes, and the upper and lower ends of the mounting boxes have two left and right sides.

[0008] The side-symmetrical fixed connection has a connecting plate;

[0009] A sliding column is vertically slidably connected inside the mounting box. An upper connecting block and a lower connecting block are fixedly connected to both ends of the sliding column, respectively. The upper connecting block and the lower connecting block slide with the mounting box and extend to the outside of the mounting box. A horizontal plate is fixedly connected to the outer wall of the upper connecting block and is arranged horizontally outward. An inclined plate is fixedly connected to the outer wall of the lower connecting block and is arranged diagonally upward outward. The end of the inclined plate away from the lower connecting block is fixedly connected to the bottom of the horizontal plate away from the upper connecting block.

[0010] A first spring is fixedly connected between the bottom of the lower connecting block and the bottom of the mounting box;

[0011] The support plate is fixedly and horizontally connected between the tops of the two horizontal plates.

[0012] A vertical mounting plate is provided on the top of the connecting plate located on the outer side. A vertical first sliding groove is provided in the center of the mounting plate. A first slider is slidably connected in the first sliding groove. A second spring is fixedly connected between the bottom of the first slider and the bottom of the first sliding groove. A horizontally arranged first hanging rod is fixedly connected between the two first sliders located on both sides.

[0013] A vertically upward-facing plate is fixedly connected to the top of the end of the horizontal plate away from the upper connecting block. A second slide groove is opened at the center of the upper side of the plate corresponding to the first slide groove. A second slider is slidably connected in the second slide groove. A third spring is fixedly connected between the bottom of the second slider and the bottom of the second slide groove. A second hanging rod is fixedly connected between the two second sliders on both sides.

[0014] The fall protection net is fixedly connected between the first hanging rod and the second hanging rod.

[0015] The mounting plate is fixedly connected to the upper side of the mounting plate. The first linkage component includes a rotating rod that is rotatably connected between the two ear plates on both sides. The outer wall of the rotating rod is fixedly connected to the outer edge of one side of the top protective plate along the axial direction.

[0016] A fixing plate is provided on the outside of the wall corresponding to the top protective plate. A vertical third sliding groove is provided in the center of the fixing plate. The third sliding groove is slidably connected to the vertical part of the L-shaped sliding plate. The horizontal part of the sliding plate away from the third sliding groove is fixedly connected to the inner outer wall of the first hanging rod.

[0017] The vertical part of the skateboard is provided with a hanging ring, which is movably engaged with a hook provided on the outer wall of the top protective plate;

[0018] The fixing plate is fixedly connected to several fourth springs that face outward and are horizontally arranged. The end of the fourth spring away from the fixing plate is movably engaged with the outer wall of the top protective plate.

[0019] The first linkage component also includes a rack fixedly connected to both sides of the second hanging rod and vertically downward, the rack meshing with a missing gear, the missing gear being rotatably connected to the outer wall of the upright plate located on the same side therewith;

[0020] The toothless block portion with missing gear is fixedly connected to a stop bar facing outward along the radial direction. The stop bar is movably engaged with the outer edge of the top protective plate on the side away from the rotating rod.

[0021] The top protective plate is an arc-shaped structure that curves inward.

[0022] The bottom of the cleaning plate slides in conjunction with the top of the sponge pad;

[0023] The second linkage component includes two pull plates that are symmetrically fixed to the outer walls on both sides of the support plate facing the wall and are vertically upward. An elastic pull rope is fixedly connected between the two pull plates and the inner side of the cleaning plate. Pull rings are symmetrically arranged on both sides of the outer wall of the cleaning plate.

[0024] The bottom of the second hanging rod is provided with two upwardly bent hanging plates corresponding to the pull ring, and the pull ring and the hanging plates are movably engaged.

[0025] The support plate is fixedly connected to a collection trough with its opening facing upwards on the side closest to the wall.

[0026] An arc-shaped guide plate, with its opening facing outwards, is fixedly connected between the tops of the two upright plates on both sides.

[0027] A reinforcing plate is fixedly connected between the top of the upright plate and the bottom of the guide plate on the side away from the upright plate.

[0028] The support frame is fixedly connected to the wall by fixing bolts.

[0029] In practical use, the entire device is fixed to the building wall using a support frame. Several units can be fixed sequentially as needed. When sand or gravel falls, it will fall through the fall net to the top of the sponge mat. In the event of a fall, the person will first fall into the fall net. If the fall point is unexpectedly outward, the person will be blocked by the elastic guide plate and drawn into the fall net. The fall net moves downward under the cushioning effect of the second and third springs. Simultaneously, the first hanging rod drives the sliding plate downward, causing the hook to disengage from the hanging ring. Under the action of the fourth spring, the top protective plate is pushed quickly towards the second hanging rod. The side closure forms an upper protection, and at the same time, the second hanging rod descends, driving the rack downwards. The rack drives the missing gear to rotate, causing the stop bar to face inwards and diagonally upwards to block the outer edge of the top protective plate and fix its position. At the same time, the second hanging rod descends, causing the hanging plate to disengage from the pull ring. Under the action of the elastic pull rope, the cleaning plate quickly slides from the top outside of the sponge pad to the side of the collection trough, cleaning the sand and gravel into the collection trough. The personnel fall into the sponge pad together with the fall net, undergoing a second buffering, and then continue to drive the support frame downwards. The support frame, under the action of the first spring, provides a third buffering, at which point the personnel's falling speed drops to zero.

[0030] The beneficial effects of this invention are as follows:

[0031] 1. This invention has a good protective effect. It reduces the falling speed of the person to zero through three buffers. Moreover, the protective surface has no rigid support structure, which effectively avoids secondary injury caused by the person colliding with the fall net.

[0032] 2. The present invention, through the first linkage component, enables the top protective plate to quickly form a closed protective state from above the person after the person falls onto the fall net, so as to avoid secondary injury to the person caused by objects that may fall during the fall.

[0033] 3. The present invention uses a second linkage component to quickly clean up the sand and gravel on the sponge mat after a person falls, thus avoiding contact with the person and causing secondary injury.

[0034] 4. The present invention has a reasonable and ingenious structural design, which utilizes the gravity of a person falling to drive the first and second linkage components to complete their protective functions, without the need for other power components, thus achieving good economic efficiency.

The third slide groove 503 is slidably connected to the vertical part of the L-shaped slide plate 504. The horizontal part of the slide plate 504 away from the third slide groove 503 is fixedly connected to the inner outer wall of the first hanging rod 113. A hanging ring 505 is provided on the vertical part of the slide plate 504. The hanging ring 505 is movably engaged with the hook 506 provided on the outer wall of the top protective plate 6. Several fourth springs 507 facing outward and horizontally arranged are fixedly connected to the fixing plate 502.

[0052] In practical use, the entire device is fixed to the building wall 12 via the support frame 1. Several of these devices can be fixed sequentially as needed. When sand or gravel falls, it will fall through the fall net 4 to the top of the sponge pad 3. The holes in the fall net 4 are large enough for small pieces of sand or gravel to pass through, while larger debris can be cleaned up promptly. In the event of a fall, the person will first fall into the fall net 4. If the person's fall point is unexpectedly off to the outside, it will also be blocked by the elastic guide plate 10 and fall into the fall net 4. The fall net 4 moves downward under the buffering action of the second spring 112 and the third spring 118. At the same time, the first hanging rod 113 drives the sliding plate 504 downward, causing the hook 506 to disengage from the hanging ring 505 and push it under the action of the fourth spring 507. The top protective plate 6 quickly closes to the side of the second hanging rod 117 to form upper protection. At the same time, the second hanging rod 117 moves downward, driving the rack 508 downward. The rack 508 drives the missing gear 509 to rotate, causing the stop bar 510 to move inward and diagonally upward to block the outer edge of the top protective plate 6 and fix its position. At the same time, the second hanging rod 117 moves downward to disengage the hanging plate 704 from the pull ring 703. Under the action of the elastic pull rope 702, the cleaning plate 8 quickly slides from the top outside of the sponge pad 3 to the side of the collection trough 9 to clean the sand and gravel into the collection trough 9. The personnel and the fall protection net 4 fall into the sponge pad 3 together and are cushioned twice. Then, the support frame 1 continues to move downward. Under the action of the first spring 108, the support frame 1 provides three cushioning actions, and at this point, the personnel's falling speed drops to zero.
