[0037] In order to better explain the present invention, and to facilitate understanding, the following Figure 1-9 , through the specific implementation method, the utility model is described in detail. Among them, the directional nouns such as "upper" and "lower" mentioned in this article are Figure 1 The orientation is referenced.

[0038] Example 1:

[0039] Reference Figures 1-9 An embodiment of the utility model provides a person-cargo separation hanging basket for a chimney 6, comprising a supporting truss 1, a person hanging basket 2, a cargo hanging basket, a first traction assembly 4 and a second traction assembly 5. The person hanging basket 2 and the cargo hanging basket are separated from each other and are both located inside the chimney 6. The supporting truss 1 is laterally arranged at the top of the chimney 6. The first traction assembly 4 and the second traction assembly 5 can respectively pull the person hanging basket 2 or the cargo hanging basket to rise and fall inside the chimney 6; the cargo hanging basket comprises an annular frame 3 and a telescopic platform 7 located at the outer edge of the annular frame 3. The telescopic platform 7 comprises a bottom plate 71 and a driving assembly 72. The bottom plate 71 is connected to the movable end of the driving assembly 72 so that adjacent bottom plates 71 can be assembled into an operating platform extending beyond the annular frame 3, so that the telescopic platform 7 compensates for the space between the cargo hanging basket and the chimney 6.

[0040] In this embodiment, the human hanging basket 2 and the cargo hanging basket are separated from each other. Therefore, during the lifting process of the human hanging basket 2 and the cargo hanging basket, the staff can be in the human hanging basket 2, and the cargo is in the cargo hanging basket, so that complete separation of people and cargo is achieved. In this way, the cargo will not cause injuries to the staff due to shaking or swaying, thereby improving the safety of construction operations in the chimney 6.

[0041] At the same time, a telescopic platform 7 is also provided on the outer edge of the annular frame 3. Since the inner wall of the chimney 6 is small at the top and large at the bottom, the telescopic platform 7 can be extended and retracted to form a working platform. The working platform can just compensate for the space between the chimney 6 and the annular frame 3, so that the hanging basket can flexibly match the shape of the chimney 6. In this way, when carrying out construction work, there will be no large gap between the annular frame 3 and the chimney 6. On the one hand, construction safety is improved, and on the other hand, it is easier for workers to get close to the chimney 6, which facilitates construction work.

[0042] Specifically, the telescopic platform 7 can be set to extend in stages, each time increasing by 500 mm, for a total of 3 times. All hydraulic support control lines are connected to a control box for synchronous control to ensure consistency in the extended length.

[0043] Specifically, the first traction assembly 4 can be configured as a fixed pulley assembly, the corresponding fixed pulley is provided on the truss, the traction member such as a winch is provided on the human hanging basket 2, and the traction rope such as a steel cable 55 passes through the fixed pulley, and the two ends are respectively connected to the traction member and the human hanging basket 2. In addition, the first traction assembly 4 is provided in at least two groups symmetrical along the vertical center line of the human hanging basket 2 to ensure the lifting stability of the human hanging basket 2.

[0044] More specifically, the supporting truss 1 and the annular frame 3 can be configured as steel structures as long as they can meet the strength requirements, which will not be described in detail here.

[0045] The driving assembly 72 includes a telescopic driving member 721 and a frame 722 . The telescopic driving member 721 is supported on the outer edge of the annular frame 3 , and the frame 722 is connected to the telescopic end of the telescopic driving member 721 .

[0046] The telescopic driving component can be an electric telescopic component, a pneumatic telescopic component or a hydraulic telescopic component. Considering the layout requirements, the electric telescopic component is the best, and the frame 722 can be a rod body.

[0047] The second traction assembly 5 includes a winch, a first fixed pulley 52, a second fixed pulley 53, a movable pulley 54 and a steel cable 55. The first fixed pulley 52 is supported at the bottom of the chimney 6, the second fixed pulley 53 is supported on the supporting truss 1, and the movable pulley 54 is supported on the cargo basket. One end of the steel cable 55 is connected to the winch, and the other end of the steel cable 55 is guided by the first fixed pulley 52, the second fixed pulley 53 and the movable pulley 54, and then supported on the supporting truss 1.

[0048] In this embodiment, the second traction member 51 is arranged at the bottom of the chimney 6, so the maintenance of the second traction member 51 will be more convenient; with the cooperation of the first fixed pulley 52, the second fixed pulley 53, the movable pulley 54 and the steel cable 55, the movable pulley 54 can amplify the traction force and reduce the load of the second traction member 51; and the fixed pulley can change the direction of the traction force, so that the overall arrangement shape of the steel cable 55 better matches the shape of the chimney 6, reducing the occupancy of the second traction component 5 and improving its structural compactness.

[0049] The second traction assembly 5 is provided as two groups symmetrical along the vertical axis of the cargo hanging basket; the second traction assembly 5 further comprises a third fixed pulley 56, and the ends of the steel cables 55 close to each other are guided by the fixed pulley and then connected as a whole.

[0050] In this embodiment, the steel cables 55 of the two sets of second traction assemblies 5 are integrally structured. In this case, the steel cables 55 are also indirectly supported on the support truss 1 after passing through the second fixed pulley 53. This arrangement improves the integrity of the second traction assembly 5, especially the steel cables 55, reduces the number of disconnection points of the steel cables 55, thereby improving the stability of the second traction assembly 5 and enhancing the ease of assembly of the second traction assembly 5.

[0051] Furthermore, since the steel cables 55 are connected as one body, the overall traction of the cargo basket can be achieved through a second traction member 51 located at the bottom of the chimney 6, making the arrangement of the second traction assembly 5 more flexible.

[0052] The first traction member and the second traction member 51 are both winches.

[0053] The cargo hanging basket also includes a partition, and a working space is formed in the annular frame 3. The partition can divide the working space into adjacent working areas; the partition is a flexible net, which is more convenient to set up. For example, the connection with the annular frame 3 can be completed by a strap, which can reduce the difficulty of installing the partition and improve the installation efficiency.

[0054] The working area includes an installation area for the control system and a storage area. The bottom surface of the working area is the bottom frame of the annular frame 3. By setting up the working area, the space of the annular frame 3 can be used more effectively.

[0055] The annular frame 3 includes a main body 31 and a connecting portion 32 that are detachably connected to each other. The connecting portion 32 is connected to the second traction assembly 5 .

[0056] In this embodiment, the connection portion 32 and the body 31 can be connected by bolts. Since the body 31 of the annular frame 3 needs to match the inner diameter requirements of different chimney models 6, its outer diameter size will have multiple models. By configuring the connection portion 32 and the body 31 as separate parts, the connection portion 32 can be produced in a single model, while the body 31 can be produced in multiple models. This allows for modular production of the connection portion 32 and the body 31, reducing the overall production cost of the annular frame 3. This configuration ensures that both the annular frame 3 and the connection portion 32 have excellent interchangeability, making the assembly of the cargo basket more flexible.

[0057] Example 2:

[0058] Reference Figure 2 and 5 In addition to all the technical solutions of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0059] The base plate 71 includes a first plate body 711 and a second plate body 712 that are slidably connected to each other. The two ends of the first plate body 711 and the second plate body 712 that are away from each other are respectively connected to the two frames 722 corresponding to the two driving components 72; the relative sliding direction of the first plate body 711 and the second plate body 712 is parallel to the tangent direction of the annular frame 3.

[0060] In this embodiment, the base plate 71 is a split structure. When the frame 722 connecting the first plate body 711 and the second plate body 712 is driven to extend synchronously by the telescopic driving member 721, the first plate body 711 and the second plate body 712 will move away from each other, so that the base plate 71 can be extended as a whole to match the radial extension working condition of the telescopic driving member 721.

[0061] When the frame 722 connecting the first plate 711 and the second plate 712 is driven to retract synchronously by the telescopic driving member 721, the first plate 711 and the second plate 712 will move away from each other, so that the overall circumferential width of the bottom plate 71 along the annular frame 3 can be shortened to match the radial retraction working condition of the telescopic driving member 721.

[0062] A mating groove is provided on the top surface of the first plate body 711, and the side of the second plate body 712 close to the first plate body 711 is a comb-tooth structure. The second plate body 712 with the comb-tooth structure slides with the mating groove of the first plate body 711 to form a flat surface on the top surface of the first plate body 711 and the second plate body 712.

[0063] Specifically, the second plate body 712 with a comb-shaped structure of the slot box forms a matching structure of the slider and the slide slot, and the structure is in the form of a straight extension so that the two frames 722 connecting the bottom plate 71 will not get stuck when they are synchronously extended and retracted.

[0064] Example 3:

[0065] Reference Figure 3 and Figure 6 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0066] The bottom plates 71 are laid on two or more adjacent frames 722 so that the upper surface of the bottom plates 71 forms a working platform. The bottom plates 71 are arranged in multiple groups radially along the annular frame 3 .

[0067] In this embodiment, the bottom plate 71 and the frame 722 are connected in an overlapping manner. The bottom plate 71 includes a plate body and locks 73 connected to both ends of the bottom plate 71 . The locks 73 are buckled onto the corresponding frame 722 .

[0068] When the frames 722 are extended, the staff can manually overlap the bottom plate 71 on the corresponding frames 722 to obtain the required working platform.

[0069] Example 4:

[0070] Reference Figure 2-9 In addition to all the technical solutions of the above-mentioned embodiment 2 or embodiment 3, the embodiment of the present utility model further has the following technical solutions:

[0071] The telescopic platform 7 also includes locks 73 connected to both ends of the base plate 71, which are buckled into the corresponding frame 722; the base plates 71 are arranged as multiple groups radially along the annular frame 3.

[0072] Based on Example 3, by setting up multiple groups of bottom plates 71, the size of each bottom plate 71 can be reduced. In this way, when the first plate body 711 and the second plate body 712 of the bottom plate 71 slide relative to each other, the change is not likely to get stuck, which is beneficial to improving the sliding stability of the first plate body 711 and the second plate body 712.

[0073] At the same time, the smaller base plate 71 is easier to process and assemble, which helps reduce production and assembly costs.

[0074] Based on Example 4, by providing multiple sets of bottom plates 71 , workers can obtain a wider working platform or a narrower working platform through flexible laying combinations, thereby better adapting to the distance requirements between the chimney 6 and the annular frame 3 .

[0075] The lock buckle 73 and the frame 722 are engaged with each other, which can realize the connection of the base plate 71 on the frame 722. At the same time, it can also realize the rapid disassembly and assembly of the base plate 71 and the frame 722, thereby improving the assembly and maintenance efficiency of the base plate 71.
