DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0023] The present application provides a technical solution:

[0024] Figures 1-5 An embodiment is shown: an assembled composite board adjustable angle hoisting device, comprising a hoisting seat 1, an angle adjusting assembly 2 is arranged inside the hoisting seat 1, and a hoisting assembly 3 is arranged below the angle adjusting assembly 2; the angle adjusting assembly 2 comprises two rotating shafts 21 which are symmetrically arranged on the inner wall of the hoisting seat 1, and the rotating shafts 21 can rotate in the same direction, a winding drum 22 is symmetrically fixed on the outer wall of the rotating shaft 21, a steel cable 23 is wound in the winding drum 22, a worm gear 24 is fixed on the outer wall of the rotating shaft 21 near the middle position, the angle adjusting assembly 2 further comprises a double-shaft motor 25 which is fixedly installed on the inner top surface of the hoisting seat 1, two output ends of the double-shaft motor 25 are both provided with a worm 26, and the worm 26 is connected with the worm gear 24 in meshing mode.

[0025] Specifically, after the double-shaft motor 25 is started as a power source, the output shaft drives the two worms 26 to rotate, the rotation of the worm 26 can drive the two worm gears 24 and the rotating shafts 21 to rotate in the same direction, and the winding drum 22 also rotates, by controlling the forward and reverse rotation of the double-shaft motor 25, the two winding drums 22 can wind or release the steel cable 23, because the steel cable 23 is connected with the hoisting assembly 3 below, when the winding or releasing of the two winding drums 22 on the steel cable 23 is inconsistent, the stress balance state of the hoisting assembly 3 will be changed, so as to realize the adjustment of the posture of the hoisting assembly 3, and further achieve the purpose of adjusting the inclination angle of the composite board.

[0026] In the present embodiment, shaft rod seats 27 are rotatably arranged on the outer wall of the worm 26 near the distal end, and the shaft rod seats 27 are fixedly installed on the inner top surface of the hoisting seat 1.

[0027] Specifically, the shaft rod seat 27 provides a rotating support point for the worm 26, so that the worm 26 will not deviate, shake or disengage from the worm gear 24 when rotating.

[0028] In the embodiment, the lifting ring 11 is arranged on the top surface of the lifting seat 1 near the middle, U-shaped limiting frames 12 are arranged on the inner top surface of the lifting seat 1 near the four corners, for limiting the steel cable 23, a crossbar 13 is arranged on the inner wall of the lifting seat 1 near the bottom, a rotating seat 14 is arranged on the bottom surface of the crossbar 13, a connecting rod 15 is rotatably arranged in the rotating seat 14, the lifting assembly 3 comprises a rectangular frame 31, a cross beam 32 is arranged on the inner wall of the rectangular frame 31 near the middle, the top surface of the cross beam 32 is fixedly connected with the bottom surface of the connecting rod 15, connecting rings 35 are fixedly arranged on the top surface of the rectangular frame 31 near the four corners, and the connecting rings 35 are fixedly connected with the ends of the steel cable 23. A plurality of steel ropes 33 are fixedly connected with the bottom surface of the rectangular frame 31, and hooks 34 are fixedly connected with the bottom ends of the steel ropes 33. The battery 4 is arranged on the inner top surface of the lifting seat 1 away from the double-shaft motor 25, for supplying power to the double-shaft motor 25.

[0029] Specifically, the U-shaped limiting frame 12 is used to limit the steel cable 23 in the vertical direction, so that the steel cable 23 can only move in the limited channel, avoiding the swinging and winding of the steel cable 23 during the winding and unwinding of the drum 22, ensuring that the tension of the steel cable 23 can accurately act on the lifting assembly 3. In addition, the combination of the crossbar 13, the rotating seat 14 and the connecting rod 15 establishes a stable and angle-adjustable connection between the lifting assembly 3 and the lifting seat 1. The connecting rod 15 rotates in the rotating seat 14, so that the rectangular frame 31 can rotate flexibly and stably during angle adjustment. The plurality of hooks 34 can lift the composite slab.

[0030] Meanwhile, the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.

[0031] In work, the lifting ring 11 is connected with the tower crane, the tower crane lowers the device above the composite slab to be lifted, and the reinforcement framework on the composite slab is hung on the hooks 34, then the tower crane lifts the device together with the composite slab and moves to a suitable position.

[0032] When it is necessary to adjust the angle of the composite slab, the double-shaft motor 25 is started, the two output ends of the double-shaft motor 25 drive the worm 26 to rotate, and since the worm 26 is meshed and connected with the worm gear 24, the two rotating shafts 21 rotate in the same direction. When the rotating shaft 21 rotates, the drum 22 rotates, thereby winding and unwinding the steel cable 23 inside the drum 22. When the winding and unwinding lengths of the two drums 22 are inconsistent, the inclination angle of the rectangular frame 31 changes, thereby adjusting the angle of the composite slab suspended by the steel ropes 33 and the hooks 34 below. This effectively solves the problem that the inclination angle of the composite slab cannot be adjusted, reduces the construction difficulty and labor intensity, and improves the accuracy of angle adjustment.

[0033] The rectangular frame 31 is connected with the connecting rod 15 through the cross beam 32, and the connecting rod 15 rotates in the rotating seat 14, so that the rectangular frame 31 can rotate flexibly and keep stable connection during the angle adjustment.
