[0026] The provision of the steel placement groove 2 makes it easy to place the steel in the lifting seat 1, the provision of the positioning component 4 makes it easy to limit the position of the steel, the provision of the lifting ring in the lifting seat 1 makes it easy to connect the hook and the wire rope in the crane, thereby facilitating the lifting, and the provision of the movable component 5 makes it easy to open the structure in the positioning component 4, thereby facilitating the taking out of the steel.

[0027] like Figure 2 - Figure 3 As shown, the positioning assembly 4 includes a fixed block 41, the rear side of the fixed block 41 overlaps the front side of the hanging seat 1, a front and rear communicating card slot 42 is opened on the left side of the front of the fixed block 41, a plate 43 is fixedly connected to the upper rear side of the fixed block 41, a movable seat 44 is movably connected to the rear side of the plate 43, the lower outer surface of the movable seat 44 is fixedly connected to the rear side of the upper surface of the hanging seat 1, a plurality of fixing bolts 45 are threadedly connected to the upper surface of the plate 43, a card block 49 is carded inside the card slot 42, a guide rod 410 is fixedly connected to the front right side of the card block 49, and the end of the guide rod 410 is away from the card block 49 A squeezing block 411 is fixedly connected, and a curved surface is provided on the side of the squeezing block 411 away from the guide rod 410. A telescopic shaft 47 is fixedly connected to the middle part of the side of the clamping block 49 away from the guide rod 410. A fixed block 46 is fixedly connected to one end of the telescopic shaft 47 away from the clamping block 49. The rear side of the fixed block 46 is fixedly connected to the front side of the hanging seat 1. A spring 48 is sleeved on the outer surface of the telescopic shaft 47. The left and right ends of the spring 48 are fixedly connected to the opposite surfaces of the clamping block 49 and the fixed block 46. The outer surface of the top plate 6 overlaps the outer surface of the squeezing block 411, and the front side of the hanging seat 1 overlaps the rear sides of the squeezing block 411 and the clamping block 49.

[0028] The steel is placed in the lifting seat 1, and the plate 43 is flipped so that the plate 43 moves inside the movable seat 44, thereby driving the fixed block 41, and then the handle in the movable assembly 5 is rotated to drive the circular block and the top plate 6, so that the outer surface of the top plate 6 and the position of the extrusion block 411 are rubbed and separated, so that the top plate 6 is in an inclined state, and at the same time, due to the elastic action of the spring 48, the telescopic shaft 47 is pulled up, so that the clamping block 49 is pushed to clamp the inside of the clamping slot 42 and drive the guide rod 410 and the extrusion block 411 to move, and then the fixing bolt 45 is rotated to tighten the steel. The phenomenon of limiting, when it is necessary to take out the steel, the handle in the movable component 5 is turned again to drive the circular block and the top plate 6 to move. When it is rotated to the appropriate position, the top plate 6 is in a horizontal state, thereby squeezing the two extrusion blocks 411 in the positioning component 4 on the left and right sides of the lifting seat 1 at the same time, and driving the card block 49 to move out from the inside of the card slot 42. At this time, the surface of the extrusion block 411 contacts the surface of the fixed block 41. At this time, the spring 48 and the telescopic shaft 47 are completely in a contracted state, and then the plate 43 is flipped upward to separate the fixing bolt 45 from the steel, which is convenient for taking out the steel.

[0029] like Figure 4 - Figure 5 As shown, the protection component 3 includes a frame 31, an elastic rubber 32 is fixedly connected to the upper surface of the frame 31, a buffer rubber 34 is slidably connected to the inner side of the frame 31, T-shaped grooves are provided on the front and rear sides of the upper surface of the buffer rubber 34, a steel plate 33 is overlapped on the upper surface of the buffer rubber 34, the upper surface of the steel plate 33 is fixedly connected to the lower surface of the hanging seat 1, the length of the buffer rubber 34 is greater than the length of the frame 31, a strip groove 35 communicating with the upper and lower sides is provided on the right side of the upper surface of the buffer rubber 34, T-shaped blocks are fixedly connected to the front and rear sides of the lower surface of the steel plate 33, the outer surface of the T-shaped block is overlapped and pressed tightly with the inner part of the T-shaped groove, and a plurality of protection plates 311 are fixedly connected to the lower inner wall of the frame 31, and the upper surfaces of the plurality of protection plates 311 overlap the lower surface of the buffer rubber 34;

[0030] When the lifting seat 1 is lifted to the specified position by the crane and lowered to contact the ground, due to the weight of the steel in the lifting seat 1, the steel plate 33 and the elastic rubber 32 are squeezed respectively to make the elastic rubber 32 shrink. At the same time, the steel plate 33 squeezes the buffer rubber 34, so that the buffer rubber 34 fits tightly with the protective plate, thereby increasing the buffering force. The arrangement of the T-shaped block and the T-shaped slide groove facilitates the installation or removal of the buffer rubber 34. When the buffer rubber needs to be installed, the buffer rubber 34 is inserted into the interior of the frame 31. Due to the arrangement of the T-shaped block, the T-shaped slide groove slides inside. Since the T-shaped slide groove in the buffer rubber 34 is deformed and squeezed while sliding, the T-shaped slide groove fits tightly with the T-shaped block, thereby limiting its position. The arrangement of the strip groove 35 facilitates the operator to have a force point on the buffer rubber 34, and facilitates the direct removal of the buffer rubber 34, thereby facilitating the removal of the buffer rubber 34.

[0031] The following is a detailed description of the working principle of the lifting protective gear of the steel structure.

[0032] By placing the steel into the lifting seat 1, and then turning the plate 43 and driving the fixed block 41, and then rotating the handle in the movable component 5 to drive the circular block and the top plate 6, the outer surface of the top plate 6 is rubbed and separated from the position of the extrusion block 411. At the same time, due to the elastic action of the spring 48, the telescopic shaft 47 is driven to make the block 49 clamp the inside of the slot 42, and then the fixing bolt 45 is rotated to tighten and limit the steel. The elastic rubber 32, the buffer rubber 34, and the protective plate 311 are arranged to provide buffer protection when subjected to force. The strip groove 35, the T-shaped block, and the T-shaped slide groove are arranged to facilitate the loading and unloading of the buffer rubber 34.

[0033] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
