Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other.

[0024] The utility model discloses a protective hanging basket for chimney construction, comprising:

[0025] The hanging basket assembly 1 is used to carry the staff for lifting operations;

[0026] A plurality of retractable support plates 2, each support plate 2 is circumferentially distributed on the top of the hanging basket assembly 1, and a first elastic unit 21 is provided between the retractable end and the fixed end of each support plate 2, the first elastic unit 21 provides a thrust for the retractable end of the support plate 2 in a direction away from the center of the chimney, and a roller 22 is also provided at one end of the retractable end of each support plate 2 away from the hanging basket assembly 1;

[0027] A plurality of connecting frames 3 are provided, each connecting frame 3 is distributed at the top end of the hanging basket assembly 1, and the connecting frame 3 is used for connecting the traction rope.

[0028] In specific implementation, when it is necessary to carry out operations, first connect each traction rope to the corresponding connecting frame 3, and each first elastic unit 21 provides a thrust for the telescopic end of the corresponding support plate 2 in the direction away from the center of the chimney. The aperture of the chimney will decrease with the increase of the chimney height. As the hanging basket assembly 1 rises in the chimney, each roller 22 contacts the inner wall of the chimney. As the hanging basket assembly 1 continues to rise, the chimney aperture of the telescopic end of each support plate 2 decreases and contracts. Each roller 22 always abuts against the inner wall of the chimney and continuously applies a thrust to the inner wall of the chimney away from the center of the chimney. During the movement of the hanging basket assembly 1, each roller 22 reduces the wear of the corresponding support plate 2 when it contacts the inner wall of the chimney. At this time, the hanging basket assembly 1 is constrained by each support plate 2 and can only move up and down.

[0029] In the utility model, through the cooperation between the hanging basket assembly 1 and the support plates 2, when the traction rope drives the hanging basket assembly 1 to rise through the connecting frames 3, the rollers 22 abut against the inner wall of the chimney and exert a thrust away from the center of the chimney. At this time, the hanging basket assembly 1 is limited at the axis of the chimney by the reaction force of the support plates 2 and is difficult to shake, thereby ensuring the work efficiency and personal safety of the staff. The support plates 2 are all arranged above the construction area, and the hanging basket assembly 1 is difficult to affect the completed construction area inside the chimney.

[0030] Preferably, the first elastic unit 21 may be a spring in the prior art.

[0031] It should be noted that each connecting frame 3 may be provided with a safety buckle on the same hook structure to prevent the traction rope from accidentally falling off from the corresponding connecting frame 3.

[0032] In one embodiment, the hanging basket assembly 1 includes a hanging basket body 12 and a positioning plate 11 disposed above the hanging basket body 12, the above-mentioned support plates 2 are circumferentially distributed on the positioning plate 11, and the connecting frames 3 are distributed on the top surface of the positioning plate 11, and a rotatable connecting component 4 is further provided between the positioning plate 11 and the hanging basket body 12, and the connecting component 4 is used to connect the hanging basket body 12 and the positioning plate 11;

[0033] The basket body 12 is provided with a driving component 5, which includes a plurality of first telescopic rods 51 distributed circumferentially on the top of the basket body 12, and each first telescopic rod 51 is distributed in a cross shape. The basket body 12 is provided with a control console (not shown in the figure), and each first telescopic rod 51 is connected to the control console signal on the basket body 12. The console can control each first telescopic rod 51 to perform telescopic work, and an abutment component 6 is provided at the end of the telescopic end of each first telescopic rod 51 away from the basket body 12. The first telescopic rod 51 can drive the corresponding abutment component 6 to move toward or away from the basket body 12.

[0034] With this design, when the hanging basket assembly 1 rises, the telescopic end of each first telescopic rod 51 drives the corresponding abutment component 6 to move away from the hanging basket body 12 until each abutment component 6 contacts the inner wall of the chimney and applies a thrust to the inner wall of the chimney away from the center of the inner wall of the chimney. At this time, each first telescopic rod 51 assists in limiting the hanging basket body 12. When it is necessary to adjust the hanging basket body 12 to the position of the working area, the staff drives the first telescopic rod 51 near the working area to retract through the control console on the hanging basket body 12, and causes the other first telescopic rod 51 opposite to the retracted first telescopic rod 51 to retract. The telescopic rod 51 is stretched, and the basket body 12 approaches the working area. The abutment parts 6 are still in abutment with the inner wall of the chimney, which ensures the stability of the basket body 12 when moving and facilitates the staff to work. While the connecting part 4 ensures the connection between the basket body 12 and the positioning plate 11, the connecting part 4 rotates with the moving direction of the basket body 12. Since the first telescopic rods 51 support the basket body 12 through the corresponding abutment parts 6, the basket body 12 will not shake significantly due to inertia during the movement, further ensuring the safety of the staff's operation.

[0035] Preferably, the first telescopic rod 51 can be an electric telescopic rod or a hydraulic telescopic rod.

[0036] It should be noted that during the ascending process, since each traction rope is connected to the corresponding connecting frame 3 and stretched straight, and each support plate 2 limits the positioning plate 11, so that the positioning plate 11 will not move toward or away from the inner wall of the chimney, the hanging basket body 12 will only drive the connecting component 4 to move together when it moves through the driving component 5. Therefore, during the movement of the hanging basket body 12, the traction rope is still in a vertical and stretched state, and the traction rope will not swing with the movement of the hanging basket body 12, reducing additional wear on equipment such as the traction rope, the connecting frame 3, and the traction device.

[0037] In one embodiment, the abutment component 6 includes a second telescopic rod 61 telescopically arranged in the telescopic end of the first telescopic rod 51, and a second elastic unit 62 is provided between the second telescopic rod 61 and the telescopic end of the first telescopic rod 51. The second elastic unit 62 is used to provide the second telescopic rod 61 with a thrust in a direction away from the center of the hanging basket body 12, and also includes a movable member 63 arranged at one end of the second telescopic rod 61 away from the first telescopic rod 51, and the movable member 63 is used to assist the movement of the hanging basket body 12.

[0038] With this design, when the hanging basket body 12 needs to be supported, each second elastic unit 62 drives the corresponding second telescopic rod 61 to move away from the center of the hanging basket body 12, until each second telescopic rod 61 drives the corresponding movable member 63 to abut against the inner wall of the chimney, and the hanging basket body 12 is limited by the reaction force of each second telescopic rod 61, and when the hanging basket assembly 1 rises, each second telescopic rod 61 will shrink as the chimney aperture decreases, so that each movable member 63 is always close to the inner wall of the chimney and applies a thrust to the inner wall of the chimney away from the hanging basket body 12, so that the hanging basket body 12 can be more stable when moving.

[0039] Preferably, the second elastic unit 62 may be a spring in the prior art.

[0040] In one embodiment, the movable member 63 includes a support block 631 arranged at an end of the second telescopic rod 61 away from the hanging basket body 12. The support block 631 is arc-shaped and has a plurality of balls 632 distributed on one side close to the inner wall of the chimney. Each ball 632 is rolled on the corresponding support block 631. When the second telescopic rod 61 is extended, each ball 632 abuts against the inner wall of the chimney.

[0041] With such a design, when the hanging basket body 12 moves by contracting one of the first telescopic rods 51, the second telescopic rods 61 arranged on both sides of the first telescopic rod 51 contract along with the movement of the hanging basket body 12, and drive the corresponding balls 632 to rotate together, and each ball 632 can not only assist in supporting the hanging basket body 12 to move better, but also reduce the wear on the inner wall of the chimney.

[0042] In one embodiment, the connecting component 4 includes a retractable connecting column 41 arranged between the positioning plate 11 and the hanging basket assembly 1, the fixed end of the connecting column 41 is hinged to the bottom surface of the positioning plate 11, and the retractable end of the connecting column 41 is hinged to the top surface of the hanging basket body 12. When the hanging basket body 12 approaches the working area, the connecting column 41 moves and rotates together with the hanging basket body 12.

[0043] With such a design, when the basket body 12 moves, the telescopic end of the connecting column 41 moves together with the basket body 12. At this time, the connecting column 41 rotates together with the moving direction of the basket body 12, and the telescopic end of the connecting column 41 is stretched, thereby ensuring that the positioning plate 11 is connected to the basket body 12 while preventing the positioning plate 11 and the traction ropes from moving during the movement of the basket body 12, thereby ensuring the stability of the positioning plate 11 and the traction ropes.

[0044] In one embodiment, a plurality of first hooks 7 are distributed on the bottom surface of the positioning plate 11, and a second hook 8 corresponding to each of the first hooks 7 is distributed on the top surface of the hanging basket body 12;

[0045] A plurality of safety ropes 9 are distributed between the positioning plate 11 and the hanging basket body 12. The two ends of each safety rope 9 are respectively hung on the corresponding first hook 7 and the second hook 8 corresponding to the first hook 7. The safety rope 9 is used to connect the positioning plate 11 and the hanging basket body 12. When the connecting component 4 works normally, each safety rope 9 is in a relaxed state, thereby reducing wear during work.

[0046] With this design, when the telescopic end of the connecting column 41 accidentally falls off, the hanging basket body 12 drops under the influence of gravity. At this time, each safety rope 9 is tightened and the positioning plate 11 is still connected to the hanging basket body 12, thereby preventing the hanging basket body 12 from accidentally falling and ensuring the safety of the staff.

[0047] It should be noted that each of the first hook 7 and the second hook 8 may be provided with a safety buckle on the same hook structure, so as to prevent the safety rope 9 from accidentally falling off from the corresponding first hook 7 and the corresponding second hook 8.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. In addition, "multiple", "multiple groups", and "several" refer to more than two.
