[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] like Figures 1-5As shown, this utility model provides a hoisting device for safety engineering, including a base plate 1. Four movable wheels 2 are symmetrically fixed at the lower corners of the base plate 1. Counterweights 3 are symmetrically fixed on both sides of the upper end of the base plate 1. An adjustment mechanism 4 is provided in the middle of the upper end of the base plate 1. A reinforcing frame 5 is fixed on the left side of the upper end of the base plate 1. A top plate 6 is provided at the top of the adjustment mechanism 4. A horizontal plate 7 is provided on one side of the lower end of the top plate 6. Hooks 8 are symmetrically fixed on both sides of the lower end of the horizontal plate 7. An anti-falling mechanism 9 is provided at the lower end of the hooks 8.

[0026] A fixing ring 10 is fixed to the outside of the hook 8. Fixing rods 11 are fixed to both sides of the fixing ring 10. A side plate 12 is fixed to the upper left side of the top plate 6. A winding reel 13 is rotatably installed on the inner side of the side plate 12. A motor 14 is fixed to one end of the side plate 12. A top frame 15 is fixed to the right end of the top plate 6. A pulley 16 is rotatably connected to the inner side of the top frame 15. A steel wire rope 17 is wound on the winding reel 13. A hanging seat 18 is fixed to the bottom end of the steel wire rope 17.

[0027] The lower end of the fixing rod 11 is symmetrically fixed to the four corners of the upper end of the lifting plate 91, and the output rod of the motor 14 is fixedly connected to the middle of the winding reel 13.

[0028] The wire rope 17 is in contact with the outside of the pulley 16 and is slidably connected. The lower end of the hanging bracket 18 is fixedly installed at the middle of the upper end of the horizontal plate 7.

[0029] In this scheme, the reinforcing frame 5 can provide stable support for the upright frame 41, the counterweight 3 can improve the stability of the device hoisting, and the pulley 16 can improve the smoothness of the wire rope 17 when it is wound up and down.

[0030] like Figure 3 As shown, the adjustment mechanism 4 includes a frame 41. The lower end of the frame 41 is fixedly installed at the middle of the upper end of the base plate 1. A second motor 42 is fixedly installed inside the lower end of the frame 41. A lead screw 43 is installed at the output end of the second motor 42. A lifting rod 44 is threadedly connected to the outside of the lead screw 43. Limiting grooves 45 are opened on both sides of the frame 41. Limiting blocks 46 are symmetrically fixed on both sides of the lower end of the lifting rod 44.

[0031] The limiting block 46 matches the limiting groove 45 and is slidably installed. The top end of the lifting rod 44 extends out of the interior of the upright frame 41. The top end of the lifting rod 44 is fixedly connected to the lower left side of the top plate 6. The rear end of the upright frame 41 is fixedly connected to the front side of the reinforcing frame 5.

[0032] In this solution, when the lifting rod 44 moves up and down, it will drive the limiting block 46 to slide synchronously in the limiting groove 45, thereby improving the movement stability of the lifting rod 44 and also limiting it. When the equipment is at a high position and daily maintenance is required, by controlling the lowering of the lifting rod 44, the height of the equipment can be easily reduced, providing convenient operating conditions for maintenance personnel and avoiding the maintenance difficulties caused by the excessive height of the equipment.

[0033] As Figures 4-5 shown, the anti-dropping mechanism 9 includes a hoisting plate 91. The upper end of the hoisting plate 91 is movably connected to the lower end of the cross plate 7. On both sides of the upper end of the hoisting plate 91, cross frames 92 are symmetrically and fixedly connected. A bidirectional screw rod 93 is rotatably installed inside the cross frames 92. On both sides of the bidirectional screw rod 93, threaded seats 94 are threadedly connected. A limiting plate 95 is fixedly arranged between the two groups of threaded seats 94. A groove 96 is opened at the lower end inside the cross frames 92. The lower end of the threaded seat 94 is fixedly connected with a slider 97. A motor three 98 is fixedly arranged at the rear end of the cross frames 92.

[0034] The cross frames 92 are in a "C" shape, and the top end of the bidirectional screw rod 93 is drivingly installed with the output end of the motor two 42.

[0035] The slider 97 matches the chute and is slidably installed.

[0036] In this solution, during the movement of the limiting plate 95, the threaded seat 94 drives the slider 97 to slide in the groove 96, which can not only play a good guiding role for the limiting plate 95, but also effectively reduce the friction during the movement process, making the movement of the limiting plate 95 smoother and more stable. The steel structure placed on the surface of the hoisting plate 91 is firmly fixed and limited. During the subsequent hoisting process of the steel structure, the steel structure will not fall off the surface of the hoisting plate 91, greatly improving the safety of engineering operations.

[0037] Next, the working principle of the hoisting device for the safety project will be specifically described.

[0038] As Figures 1-5As shown, when using this safety engineering hoisting device, the device can be moved to a suitable position using the movable wheels 2. Then, engineering steel structures of the same length can be neatly stacked on the surface of the hoisting plate 91. Next, the motors 98 on both sides are started, driving the double-acting screws 93 on both sides to rotate. The rotating double-acting screws 93 then cause the threaded seats 94 on both sides to gradually move closer together, allowing the threaded seats 94 to move towards the center position of the double-acting screws 93. As the two threaded seats 94 move closer, they in turn drive the limiting plates 95 on both sides to move, causing the limiting plates 95 to contact and clamp the front and rear sides of the placed engineering steel structure. This provides a fixed and limiting effect on the steel structure placed on the surface of the hoisting plate 91. The function of this device is to prevent the steel structure from falling off the surface of the lifting plate 91 during subsequent steel structure lifting, thereby improving the safety of the project. By starting motor 14, motor 14 drives the winding reel 13 to rotate, causing the winding reel 13 to wind up the wire rope 17. The wire rope 17 then drives the horizontal plate 7, the fixed rod 11, and the lifting plate 91 to rise synchronously through the lifting seat 18, thus facilitating the lifting. By starting motor 2 42, motor 2 42 drives the threaded lifting rod 44 to move up and down, causing the lifting rod 44 to move the top plate 6 synchronously. The top plate 6 can synchronously drive the winding reel 13 and the lifting plate 91 installed thereon, allowing the equipment to be flexibly adjusted according to actual needs during lifting operations, which greatly improves the effectiveness of the device.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
