The cross bar 3 and the suspension cable 4 are used to enable the traction machine 5 to move inside the top box 2 to hoist and transfer building materials, etc.; a traction machine 5 is assembled in the middle of the cross bar 3, and the cross bar 3 is symmetrically arranged about the central axis position of the traction machine 5. The symmetrically arranged cross bar 3 makes the traction machine 5 not easy to shake or tilt when sliding; a traction seat 6 is installed at the top end of the traction machine 5 by bolts, a traction wheel 7 is installed inside the traction seat 6 through a rotating shaft, and the suspension cable 4 is penetrated through the inside of the traction wheel 7. A motor 8 is installed on the outer wall of one side of the traction seat 6 by bolts, and the output shaft of the motor 8 is connected to one end of the outer wall of the traction wheel 7 through a bearing. The traction wheel 7 is rotationally connected with the traction machine 5 through the output shaft of the motor 8 and the traction seat 6, and the traction machine 5 is slidably connected with the cross bar 3 through the suspension cable 4 and the traction wheel 7. A suspension cable 9 is wound around the traction end of the traction machine 5, and the other end of the suspension cable 9 is connected to the lower surface of one end of the traction machine 5. The lower end of the suspension cable 9 is connected to a suspension pulley 10. The middle outer wall of the suspension pulley 10 is sleeved with a lower sling 11 through a bearing. The suspension pulley 10 is rotationally connected with the lower sling 11 through the suspension cable 9 and the traction end of the traction machine 5. The suspension pulley 10 rotating inside the lower sling 11 remains vertical under the gravity of the lower sling 11 and the hook 12, and the structure of the movable pulley reduces the traction burden of the traction machine 5; a hook 12 is welded on the outer wall of the lower end of the lower sling 11, and the hook 12 is telescopically connected with the traction machine 5 through the lower sling 11 and the suspension cable 9. The provided hook 12 realizes the hoisting function at the building construction site through the lifting of the suspension pulley 10 and the lower sling 11 on the suspension cable 9, and the hoisted materials can be moved through the sliding of the traction machine 5 on the cross bar 3, and the hoisting height can also be adjusted by the number of assembled pillars 1, making the applicability of the hoisting device better under different construction requirements and easy to use.

[0023] Please refer to Figure 1 and Figure 3, A hoisting device for building construction, comprising: A side support plate 13 is installed on the outer wall of one side of the pillar 1 through bolts. A detachable structure is formed between the side support plate 13 and the pillar 1. The detachable side support plate 13 is used for installation and fixation according to requirements. An armrest 14 is fixed on the outer wall of the side support plate 13, and the armrests 14 are evenly distributed at equal intervals along the outer wall of one side of the side support plate 13. The provided armrests 14 are used to enable workers to climb to a height through the side support plate 13 fixed on the pillar 1 to perform maintenance and repair on structures such as the traction machine 5, the sling 4, and the cross bar 3.

[0024] Please refer to Figure 1 and Figure 4 , A hoisting device for building construction, comprising: A binding ring 15 is provided around the outer wall of one end of the sling 4 away from the traction machine 5. A hemispherical package block 16 is fixed on the outer wall of the binding ring 15. The binding ring 15 and the package block 16 are evenly distributed at equal intervals along the outer walls of both ends of the sling 4. The sling 4 is engaged with the top box 2 through the binding ring 15 and the package block 16. The provided binding ring 15 and package block 16 are used to clamp and stabilize the sling 4 at one end of the top box 2 away from the traction machine 5, preventing the sling 4 from falling off the top box 2 due to the dragging of the traction machine 5 and the traction seat 6 after being threaded, affecting the normal operation of the traction machine 5.

[0025] Working principle: For this type of hoisting device for building construction, first, the staff selects an appropriate number of pillars 1 according to the building construction requirements and assembles them using fasteners. Then, according to the material movement distance and the load level of the traction machine 5 on the cross bar 3, a cross bar 3 of appropriate length is selected and welded inside the top box 2, and the top box 2 is assembled at the top of the pillar 1, enabling the traction machine 5 to move inside the top box 2 by sliding on the cross bar 3. Subsequently, a sling 4 is threaded through the traction seat 6 at the upper end of the traction machine 5 and the inside of the traction wheel 7, and both ends of the sling 4 are threaded inside the top box 2. The binding ring 15 and the package block 16 are fastened at both ends of the sling 4, causing both ends of the sling 4 to be engaged with the outer wall of the top box 2, thereby maintaining a relatively straight state at both ends of the sling 4, facilitating the traction machine 5 to slide on the cross bar 3 through the rotation of the output shaft of the motor 8 and the traction wheel 7 to achieve the horizontal movement of the lifted material inside the pillar 1. Finally, when the traction end of the traction machine 5 rotates, it drives the wound cable 9 to be released or recovered at the lower end of the traction machine 5, thereby causing the lifting pulley 10 and the lower lifting tool 11 sleeved at the lower end of the cable 9 to lift and lower at the lower end of the traction machine 5. The lower lifting tool 11 lifts the material through the hook 12. When it is necessary to perform maintenance and repair on the traction machine 5 or other structures, workers can climb to a height through the installed side support plate 13 and armrest 14 to perform operations, reducing the maintenance difficulty.
