Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude operations, in particular to a lifting hanging basket for high-altitude construction operations. Background Art

[0002] The hanging basket is a construction tool for high-altitude operations in construction projects. It is used for curtain wall installation and exterior wall cleaning. The cantilever mechanism is erected on a building or structure. The lifting mechanism is used to drive the suspension platform. The construction facility runs up and down along the facade of the building or structure through steel cables. It is also a working platform set up for operators.

[0003] After searching, it was found that the Chinese utility model patent with authorization announcement number CN215212266U discloses a high-altitude work hanging basket. When the staff finds that they have forgotten some tools or the materials are insufficient after ascending, they can start the motor, the motor rotates forward, drive the winding wheel to rotate forward, thereby releasing the lifting rope, and lowering the box, so that the personnel on the ground can put the tools into the box, and then start the motor, the motor reverses and drives the winding wheel to reverse, so as to reel in the lifting rope, thereby raising the box, so that the staff on the hanging basket can get the required tools from the inside of the box.

[0004] Further search revealed that a Chinese utility model patent with authorization announcement number CN218305883U discloses a fire-fighting device for glass fiber reinforced plastic chimney construction. When a fire occurs, the fire-extinguishing device is installed on the steel rope of the lifting mechanism, and the fire-extinguishing device is lifted upward through the lifting mechanism to quickly extinguish the fire and prevent the fire from spreading.

[0005] In both of the above patent documents, the box or the fire extinguishing device needs to be pulled up by a steel rope, but the steel rope is extremely unstable and can easily cause the ascending vehicle to sway, which can easily cause the items in the vehicle to fall, and can easily cause the vehicle to collide with the wall, causing danger. Moreover, after the steel rope breaks, the brake cannot be applied in time, and the broken steel rope cannot be clamped, so the steel rope is easy to rebound, causing danger.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1 A lifting hanging basket for high-altitude construction work includes a top frame 1, on which a wire-retracting device 2 is provided. One end of the top frame 1 is fixedly connected to a pulley-type safety lock 3, and a steel rope on the wire-retracting device 2 passes through the pulley-type safety lock 3, and a hanging basket 4 is connected to the passing end.

[0028] Specifically, Figure 1 As shown, the retractable wire device 2 includes bearing seats 201 fixed on both sides of the top frame 1, and the first rotating shaft 202 is rotatably connected to the two bearing seats 201 through bearings, and a retractable wire wheel 203 is fixed on the first rotating shaft 202, and one end of the first rotating shaft 202 is connected to a driven wheel 204, and a reduction motor 205 is provided on the top frame 1, and the reduction motor 205 is connected to a transmission shaft through a coupling, and a driving wheel 206 is connected to the transmission shaft, and the driving wheel 206 and the driven wheel 204 are connected through a transmission belt transmission, and the steel rope is wound on the retractable wire wheel 203. The reduction motor 205 is controlled to work, and the first rotating shaft 202 is driven to rotate through the cooperation of the driving wheel 206, the transmission belt and the driven wheel 204, thereby driving the retractable wire wheel 203 to rotate, so as to reel or release the steel rope, thereby driving the hanging basket 4 to rise and fall.

[0029] like Figure 2 , Figure 3 and Figure 4As shown, the pulley type safety lock 3 includes a fixed block 301 fixedly connected to the top frame 1, and the outer end of the fixed block 301 is welded with two side plates 302, and the outer ends of the two side plates 302 are rotatably connected with a second shaft 303, and a first guide wheel 304 is fixed on the second shaft 303, and connecting plates 305 are fixed on both sides of the first guide wheel 304 on the second shaft 303, and a cross bar 306 is fixed on the upper part between the two connecting plates 305, and a third shaft 307 is rotatably connected between the two connecting plates 305. A second guide wheel 308 is fixed on the third shaft 307, and the cross bar 306 and the second guide wheel 308 are both located below the first guide wheel 304; between the two side plates 302 near the fixed block 301 A pressure block 309 and a mounting block 310 are welded, and a spring 311 is connected to the mounting block 310. The end of the spring 311 away from the mounting block 310 is connected to the cross bar 306. The steel rope passes through the first guide wheel 304 and passes through the second guide wheel 308 from the bottom of the cross bar 306, and then passes through the second guide wheel 308, and the passing end is connected to the hanging basket 4; one end of the second rotating shaft 303 is also connected to a limiting sleeve 312, and the side of the limiting sleeve 312 away from the fixed block is connected to an L-shaped plate 313, and the L-shaped plate 313 abuts against a side of one of the connecting plates 305 away from the fixed block. When the steel rope presses down the second guide wheel 308, the L-shaped plate 313 can prevent the connecting plate 305 from rotating to the side away from the fixed block 301. In the process of pulling the hanging basket 4 by the steel rope, when the steel rope is not broken, due to the gravity of the hanging basket 4, the steel rope will squeeze the second guide wheel 308, so that the connecting plate 305 is in a vertical state. At this time, the spring 311 is in a stretched state. When the steel rope breaks, the second guide wheel 308 rotates the connecting plate 305 counterclockwise with the second rotating shaft 303 as the center under the action of the spring 311 until the second guide wheel presses the steel rope on the pressure block. In order to further compress the steel rope, an arc groove 314 cooperating with the second guide wheel is provided on the pressure block 309, so that the second guide wheel can press the steel rope in the arc groove, thereby increasing the compression length of the steel rope, preventing the steel rope from rebounding, and reducing the occurrence of danger.

[0031] Specifically, the anti-deflection rod 5 is formed by connecting several connecting rods 501 end to end, and flanges 502 are welded at both ends of the connecting rod 501. Adjacent connecting rods 501 are connected to the flanges 502 by bolts. The topmost connecting rod 501 is connected to the top frame 1 by flanges, and the bottommost connecting rod 501 is fixed to the ground by flanges. The aperture of the sliding sleeve 6 is larger than the diameter of the flange 502, so that when the hanging basket 4 rises, the sliding sleeve 6 will not collide with the flange 502; and the anti-deflection rod 5 is formed by connecting several connecting rods end to end, and the number of connecting rods 501 to be installed can be selected according to the construction height to achieve the required height, and adjacent connecting rods 501 only need to be fixed by bolts, which is convenient for assembly and disassembly. The connecting rod 501 is provided with several positioning holes, and the sliding sleeve 6 is provided with screw holes that match the positioning holes. When the hanging basket 4 moves to the required position, the sliding sleeve 6 is fixed to the connecting rod 501 by bolts for construction.
