The construction facility runs up and down along the facade of the building or structure through the steel wire rope. It is also a working platform set up for operators.

[0003] Since the steel wire rope is a flexible structure, the lifting mechanism can only move vertically up and down along the steel wire rope, and cannot be adjusted horizontally according to the facade of the building, which brings inconvenience to the construction. Therefore, a retractable and self-balancing construction hanging basket system is urgently needed to solve the shortcomings of the existing technology. Summary of the invention

DETAILED DESCRIPTION

[0017] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0018] refer to Figure 1As shown, the present invention provides a retractable self-balancing construction hanging basket system, including: a lifting mechanism, the output end of the lifting mechanism is connected to a basket mechanism, the basket mechanism includes: two symmetrically arranged extended arms 1, the bottom ends of the two extended arms 1 are rigidly connected to an outer basket 2, the inner basket 3 is slidably arranged inside the outer basket 2, two groups of balancing devices 4 are arranged between the outer basket 2 and the inner basket 3, the two balancing devices 4 are connected by a thick steel pipe 5, and the two extended arms 1 are both hinged with a limited sliding link 6, and the other ends of the two limited sliding links 6 are respectively hinged with the two vertex corners of the inner basket 3. The two vertex corners of the inner basket 3 are connected to the extended arm 1 by the limited sliding link 6, so that the inner basket 3 is safe and stable. The extended arm 1 can improve the position of the hanging point, increase the anti-overturning moment of the basket mechanism, and prevent the construction personnel inside from tilting due to the center offset when moving.

[0019] As a preferred embodiment, the hoisting mechanism comprises: a bottom plate 7, on which a hanger 8, a hoist 9 and a control box 10 are arranged in sequence from front to back, and the control box 10 is electrically connected to the hoist 9. A double-row fixed pulley block 11 is symmetrically arranged at the top of the hanger 8, and the steel wire rope of the hoist 9 is connected to the top of the extended boom 1 through the double-row fixed pulley block 11. The hoist 9 is used as a power source, and different types of hoists 9 can be selected to meet the requirements for working load and lifting height. The hoist 9 uses a high-power motor to coaxially drive two rollers as a lifting device, so that the lifting speeds at both ends are kept synchronous and the basket mechanism is kept horizontal. The hanger 8 is made of hot-dip galvanized square steel, and the stability of the triangle is used to increase the overall rigidity of the hanger 8. The hoist 9 is placed at the rear of the hanger 8 as a counterweight for the hanger 8. If the weight is not enough, a counterweight block can be added on this basis. A double-row fixed pulley block 11 is installed on the top of the hanger 8, and the wire rope passes through the middle of the double-row fixed pulley block 11 to prevent the wire rope from coming out.

[0020] As a preferred embodiment, the top of the extended boom 1 is rigidly connected with an anti-tilt device 12, and the end of the anti-tilt device 12 away from the extended boom 1 is sleeved with a steel wire rope. The hanger 8 is provided with an anti-top switch 13 at the position corresponding to the anti-tilt device 12 below, and the anti-top switch 13 is electrically connected to the control box 10. When the basket mechanism tilts too much, the steel wire rope will touch the anti-tilt device 12, thereby triggering the short circuiter to stop the system from working, preventing the basket mechanism from being dangerous due to excessive tilt; when the basket mechanism rises to the top, the anti-tilt device 12 will touch the anti-top switch 13 on the top hanger 8, and send a stop command to the winch 9 through the control box 10 to prevent the top from falling.

[0021] As a preferred embodiment, the balancing device 4 includes: an electric push rod 14, a driving arm 15 and a transmission connecting rod 16, one end of the electric push rod 14 is hinged to the top of the outer basket 2, the driving arm 15 is rotatably set on the side wall of the outer basket 2 through a rotating shaft 17, the output end of the electric push rod 14 is hinged to the driving arm 15, the other end of the driving arm 15 is hinged to the transmission connecting rod 16, and the other end of the transmission connecting rod 16 is hinged to the bottom corner of the inner basket 3. The balancing device 4 also includes: a synchronizer, and the two electric push rods 14 are synchronously controlled by the synchronizer. The upper end of the driving arm 15 is driven by the electric push rod 14 to tilt outward, so that its lower end pushes the inner basket 3 inward through the transmission connecting rod 16, increasing the width of the basket mechanism, thereby increasing the construction work space and extending the working range horizontally inward. The driving arm 15 is made of thick steel plate, and its size and weight are designed according to the inner basket 3. Its self-balancing working principle is: the torque added to the basket mechanism by the upper part of the driving arm 15 tilting outward and the torque added to the basket mechanism by the inner basket 3 extending outward (relative to the basket itself) offset each other, maintaining the overall balance of the basket mechanism.

[0022] As a preferred embodiment, a plurality of mounting holes are provided at the upper end of the driving arm 15, and the thick steel pipe 5 can be detachably mounted on the mounting holes corresponding to the two driving arms 15. The thick steel pipe 5 can assist the driving arms 15 on both sides to move synchronously, and at the same time, the magnitude of the torque generated by the driving arm 15 after tilting can be fine-tuned by adjusting the upper and lower mounting positions of the thick steel pipe 5.

[0023] The working principle of the present invention is:

[0024] 1. When the driving arm 15 tilts to the left, the force arm on the left will increase, resulting in an increase in the torque on the left; at the same time, its lower end will push the inner basket 3 on the right to extend to the right, increasing the force arm on the right, thereby increasing the torque on the right. The working principle of the balancing device 4 is to keep the torques on both sides increasing and decreasing synchronously, thereby achieving the design purpose of self-balancing.

[0025] 2. If the basket mechanism overturns, it will rotate with the wire rope hanging point as the center of the circle. The anti-overturning lever arm is the distance from the center of gravity of the basket mechanism to the hanging point. The center of gravity of the basket mechanism is roughly at the horizontal center of the basket mechanism. By increasing the length of the extended boom 1, the hanging point can be raised, that is, the anti-overturning lever arm is increased, thereby increasing the anti-overturning ability of the basket mechanism.
