[0002] A building construction platform is a peripheral protection facility specifically used for workers to operate at the construction site and solve vertical and horizontal transportation erection. It is mainly used in places such as the exterior wall, interior decoration, or areas with high floors that are not directly constructible on construction sites. The high-rise construction intelligent lifting platform is made of pure steel, and the peripheral protection net is made of double-layer wire mesh, effectively reducing the accident rate of high-altitude falls and completely preventing fires. The frame body is directly connected to the building body by fully enclosed fixed formwork boards, just like indoor operations.

[0003] However, the entire vehicle body still has the defect of unstable state because the vehicle body is loaded by wheels and requires some legs that are easy to use and can be conveniently stored to support. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, one of the purposes of the present invention is to provide a multifunctional safety protection device for building construction.

[0005] One of the purposes of the present invention is achieved by adopting the following technical solutions: A multifunctional safety protection device for building construction, including two connecting frames installed on the construction lifting trolley and on both sides. On the adjacent sides of the two connecting frames, fixing seats are welded near the centers of the upper and lower sides, and on the rear sides of the adjacent two fixing seats near the center, a movable plate is jointly movably connected. On the top of the movable plate located at the top, a plug board is welded near the center. A jack is opened near the center of the top cavity of the plug board, and a plug rod is movably connected in the jack cavity. The left and right ends of the plug rod penetrate through the jack cavity. A fixing groove is opened near the center of the left end of the plug rod cavity. On the inner walls of the left and right sides of the fixing groove near the center, I-shaped sliding rods are connected. A sliding plate is jointly sleeved on the two I-shaped sliding rods near the top. A tongue is connected near the center of the top of the sliding plate. On the sides of the two connecting frames far from the center of the movable plate cavity, there are bracket bodies respectively. Fixed frames are sleeved near the upper and lower ends of the two bracket bodies. The sides of the two fixed frames on the left and right sides near the center of the adjacent connecting frame cavity are respectively connected to the sides of the adjacent connecting frame far from the center of the movable plate cavity near the upper and lower sides.

[0006] Furthermore, the two fixed frames on the left and right sides are symmetrically arranged up and down with the center of the adjacent connecting frame cavity as the axis of symmetry, and placing holes are opened near the centers of the upper and lower sides of the two fixed frames on the left and right sides.

[0007] Furthermore, on the inner walls of the front and rear sides of the two fixing frames on the left and right sides near the centers of the left and right sides, limiting rods are commonly welded. On the adjacent two limiting rods near the center, two positioning plates are commonly sleeved, and on the adjacent sides of the two positioning plates near the center, arc-shaped card slots are opened.

[0008] Furthermore, on the adjacent two positioning plates, on the sides away from the centers of the inner cavities of the adjacent fixing frames near the center, threaded rods are fixedly connected. On the front and rear sides of several fixing frames near the center, through holes are opened, and on the ends of the adjacent two threaded rods away from the centers of the inner cavities of the adjacent fixing frames, they are movably connected in the inner cavities of the adjacent through holes.

[0009] Furthermore, on the ends of the adjacent two threaded rods away from the centers of the inner cavities of the adjacent fixing frames, driving sleeves are sleeved. On the adjacent sides of the adjacent two driving sleeves, they are respectively movably connected to the front and rear sides of the adjacent fixing frames near the center. In the inner cavities of several driving sleeves near the center, threaded holes are opened, and on the inner walls of several threaded holes, internal threads matching the adjacent threaded rods are opened.

[0010] Furthermore, a return spring is welded near the center at the bottom of the sliding plate, and the bottom end of the return spring is connected to the inner wall of the bottom of the fixed groove near the center.

[0011] Furthermore, a fixing spring is welded near the center at the right end of the insertion rod, and the right end of the fixing spring is connected to the left side of the right connecting frame near the center at the top.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the mutual cooperation of components such as the connecting frame, movable plate, fixed seat, insertion plate, sliding plate, tongue, I-shaped sliding rod, insertion rod, fixing spring, and return spring, the present invention can conveniently fix the three movable plates in a horizontal state, so as to conveniently expand the support body for support work. At the same time, when the three movable plates are fixed in a state approaching vertical, the support body can be contracted for convenient storage. The structure is simple, the operation is convenient, and the practicability is improved.

[0019] Please refer to Figures 1 to 4 , the present invention provides a technical solution: Embodiment 1: A multifunctional safety protection device for building construction, including two connecting frames 1 installed on the construction lifting trolley 20 and on both sides. Fixed seats 3 are welded near the centers of the upper and lower sides of the adjacent sides of the two connecting frames 1. A movable plate 2 is movably connected to the rear sides of the adjacent two fixed seats 3 near the center. A plug plate 10 is welded near the center of the top of the movable plate 2 located at the top. A jack is opened near the center of the top of the inner cavity of the plug plate 10. A plug rod 14 is movably connected to the inner cavity of the jack. A fixing spring 15 is welded near the center of the right end of the plug rod 14. The right end of the fixing spring 15 is connected to the left side near the center of the top of the right connecting frame 1. Both the left and right ends of the plug rod 14 penetrate through the inner cavity of the jack. A fixing groove is opened near the center of the left end of the inner cavity of the plug rod 14. I-shaped sliding rods 13 are connected to the inner walls near the centers of the left and right sides of the fixing groove. A sliding plate 11 is sleeved on the two I-shaped sliding rods 13 near the top. A reset spring 16 is welded near the center of the bottom of the sliding plate 11. The bottom end of the reset spring 16 is connected to the inner wall near the center of the bottom of the fixing groove. A tongue 12 is connected near the center of the top of the sliding plate 11. Support bodies 5 are arranged on both sides of the two connecting frames 1 away from the center of the inner cavity of the movable plate 2. Fixed frames 4 are sleeved on the upper and lower ends of the two support bodies 5. The two fixed frames 4 located on the left and right sides are symmetrically arranged up and down with the center of the inner cavity of the adjacent connecting frame 1 as the axis of symmetry. Placement holes are opened near the centers of the upper and lower sides of the two fixed frames 4 located on the left and right sides. The sides of the two fixed frames 4 located on the left and right sides near the center of the inner cavity of the adjacent connecting frame 1 are respectively connected to the sides near the upper and lower sides of the adjacent connecting frame 1 away from the center of the inner cavity of the movable plate 2. It should be noted that the bottom of the support body 5 can be screwed with legs as shown in Figure 1 shown, and the length of the movable plate 2 can be selected according to the requirements of the vehicle body; Embodiment 2: Limiting rods 9 are jointly welded to the inner walls near the centers of the front, rear, left, and right sides of the two fixed frames 4 located on the left and right sides. Two positioning plates 8 are jointly sleeved on the adjacent two limiting rods 9 near the center. Threaded rods 7 are fixedly connected to the sides of the adjacent two positioning plates 8 away from the center of the inner cavity of the adjacent fixed frame 4 near the center. Driving sleeves 6 are sleeved on one ends of the adjacent two threaded rods 7 away from the center of the inner cavity of the adjacent fixed frame 4. The adjacent sides of the adjacent two driving sleeves 6 are respectively movably connected to the front and rear sides near the center of the adjacent fixed frame 4. Threaded holes are opened near the centers of the inner cavities of several driving sleeves 6. Internal threads matching the adjacent threaded rods 7 are opened on the inner walls of several threaded holes. Openings are opened near the centers of the front and rear sides of several fixed frames 4. One ends of the adjacent two threaded rods 7 away from the center of the inner cavity of the adjacent fixed frame 4 are movably connected to the inner cavities of the adjacent openings. Arc-shaped clamping grooves are opened near the centers of the adjacent sides of the two positioning plates 8, which is convenient for quickly fixing the support body 5 inside the two fixed frames 4 on the left and right sides.

[0020] Working principle: When in use, the user places the two bracket bodies 5 into the inner cavities of the two fixing brackets 4 on the left and right through the placing holes on the left and right sides. Then, the user rotates two adjacent driving sleeves 6 forward or backward in sequence, so that the two adjacent driving sleeves 6 can drive the two adjacent threaded rods 7 to gradually move into the inner cavities of the adjacent fixing brackets 4. At this time, the two adjacent threaded rods 7 can drive the two adjacent positioning plates 8 to move towards the adjacent side on the two adjacent limiting rods 9 and contact the side walls of the adjacent bracket bodies 5, thereby fixing the two bracket bodies 5 in the inner cavities of the two fixing brackets 4 on the left and right, enabling the bracket bodies 5 to be quickly connected to the folding mechanism. After the bracket bodies 5 are fixed, the user then pulls the connecting frame 1 on the right to drive the three movable plates 2 to gradually rotate towards the horizontal state. When the three movable plates 2 tend to be in the horizontal state, the staff pushes the plug rod 14 to the left, so that the plug rod 14 passes through the inner cavity of the jack. At this time, the external force applied to the return spring 16 disappears and it begins to extend outwards, thereby driving the sliding plate 11 to slide upwards on the two I-shaped sliding rods 13, pushing the tongue 12 out of the inner cavity of the fixed groove and contacting the left side of the insertion plate 10, thereby fixing the positions of the three movable plates 2, and unfolding the bracket bodies 5 for supporting work. When the bracket bodies 5 need to be retracted, the user pushes the tongue 12 into the inner cavity of the fixed groove. At this time, the external force applied to the fixed spring 15 disappears and it begins to contract inwards, thereby quickly pulling the plug rod 14 out of the inner cavity of the jack. At this time, the limiting force applied to the three movable plates 2 disappears, and the user pushes the connecting frame 1 on the right to the left to reset the bracket bodies 5 and complete the contraction into a whole for easy storage. Thus, by conveniently fixing the three movable plates 2 in the horizontal state, the bracket bodies 5 can be conveniently unfolded for supporting work. At the same time, when the three movable plates 2 are fixed in a state close to the vertical state, the contraction of the bracket bodies 5 can be completed for easy storage. The structure is simple, easy to operate, and improves the practicability. The above is the entire working process of the present invention.

[0021] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantive changes and substitutions made by those skilled in the art based on the present invention fall within the scope of protection required by the present invention.
