[0052] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0053] like Figure 1-11 As shown, the present invention includes an automatic climbing hanger for adding an elevator to an old building. The added elevator 1 is located outside the old building. The added elevator 1 includes a foundation pile 10 and a plurality of vertically connected elevator shaft monomers 11. The plurality of elevator shaft monomers 11 form an elevator shaft. The elevator shaft monomer 11 located at the bottom is connected to the foundation pile 10. The elevator shaft monomer 11 includes four square tube columns 12 arranged in a vertical direction, and a plurality of cross beams 13 connecting two square tube columns 12 on the same side. Both ends of the cross beam 13 are connected to the corresponding square tube columns 12 through angle steels 14.

[0054] The overall height of the automatic climbing hanger is higher than the height of the elevator shaft unit 11. The automatic climbing hanger includes: a climbing mechanism 2, a hoisting mechanism 3 and a limiting fixing mechanism 4, wherein the climbing mechanism 2 includes a support frame assembly 20 located in the additional elevator 1 and a driving assembly 200 for driving the support frame assembly 20 to climb up and down along the additional elevator 1. The hoisting mechanism 3 is arranged on the top of the support frame assembly 20, and is used to lift the various components in the elevator shaft unit 11 for on-site assembly by the staff. The limiting fixing mechanism 4 is arranged on the support frame assembly 20, and is used to limit the support frame assembly 20 to move up and down only in the additional elevator 1, and cooperate with the elevator shaft unit 11 to fix the support frame assembly 20 that has climbed into place in the additional elevator 1, thereby preventing the entire automatic climbing hanger from moving downward.

[0055] The old building elevator 1 is basically built in old residential areas, where the construction conditions are relatively limited, the available sites are small, and many project sites cannot accommodate cranes. The old building elevator 1 project has been developed for nearly ten years, and the elevator projects with better construction conditions have basically been completed. The remaining elevator 1 projects are basically limited in conditions and difficult to access cranes. This makes it difficult to implement elevator projects in some areas, causing inconvenience to people in the area.

[0056] When assembling a traditional additional elevator 1, a crane will be used to lift an entire elevator shaft unit 11, and then the adjacent elevator shaft units 11 will be connected. However, in areas with limited conditions, cranes cannot enter, which makes it difficult to advance the project of adding elevators 1 in areas with poor construction conditions. For this reason, the present application sets up an automatic climbing hanger to cooperate with the additional elevator shaft. After the automatic climbing hanger is assembled on site, the automatic climbing hanger can climb up along the additional elevator shaft, and then lift the components in the elevator shaft unit 11, and assemble the elevator shaft directly on site, which solves the problem of limited construction sites and reduces the cost of using cranes.

[0057] In this embodiment, the automatic climbing hanger is used as follows: first, the elevator shaft monomer 11 of the first layer is directly connected to the foundation pile 10, so the staff can directly install the elevator shaft monomer 11 of the lowest layer. Then the staff installs the entire automatic climbing hanger in the elevator shaft monomer 11. At this time, the automatic climbing hanger can cooperate with the elevator shaft monomer 11, and the climbing mechanism 2 is started, and the entire automatic climbing hanger can climb up a distance along the elevator shaft monomer 11. Then, after the climbing hanger is fixed in the elevator shaft monomer 11 of the first layer by the limiting fixing mechanism 4, the square column 12 in the second layer can be lifted by the lifting mechanism 3 in the automatic climbing hanger to complete the docking with the square column 12 of the first layer, and then other components are lifted to complete the installation of the elevator shaft monomer 11 of the second layer. Then, the automatic climbing hanger continues to climb up to the elevator shaft monomer 11 of the second layer, and the installation of the elevator shaft can be completed by this reciprocating process.

[0058] like Figures 2 to 8 As shown, as a further solution of this embodiment, the support frame assembly 20 includes four square support columns 21 arranged in the vertical direction and a plurality of support plates 22 arranged between the four square support columns 21 at intervals from top to bottom. The support frame assembly 20 also includes a plurality of first support arm groups 23 that connect the square support columns 21 on the same side and are used to carry the support plates 22. The first support arm groups 23 are detachably connected to the corresponding square support columns 21. In this embodiment, the support assembly 30 is mainly composed of four square support columns 21, a plurality of support plates 22, and a plurality of first support arm groups 23. The parts are simple and convenient for users to assemble on site.

[0059] The driving assembly 200 includes a first electric winch 201 fixedly mounted on a support plate 22 and a hanging beam 202 mounted in the elevator shaft unit 11. The driving assembly 200 also includes a first pulley 203 disposed at the bottom of the hanging beam 202. Both ends of the hanging beam 202 are respectively detachably connected to the corresponding cross beam 13. The steel wire rope of the first electric winch 201 is cooperatively connected to the first pulley 203.

[0060] In this embodiment, there are two support plates 22, and the first electric winch 201 in the drive assembly 200 is fixedly installed on the support plate 22 located on the lower layer. The two ends of the hanging beam 202 are installed between the cross beams 13 in the elevator shaft monomer 11. When the automatic climbing hanger needs to climb, the hanging beam 202 is installed in the elevator shaft monomer 11 on the upper layer. Subsequently, the first electric winch 201 is started, and the steel strand of the first electric winch 201 cooperates with the hanging beam 202 to lift the entire automatic climbing hanger and move it upward. After moving into position, the support frame assembly 20 is fixed in the elevator shaft monomer 11 by the limiting fixing mechanism 4, thereby limiting the downward movement of the entire automatic climbing hanger.

[0061] like Figures 2 to 10 As shown, as a further solution of this embodiment, the limiting and fixing mechanism 4 includes a limiting component 40 for limiting the support frame assembly 20 to move up and down only in the added elevator 1, and a fixing component 400 for fixing the support frame assembly 20 that climbs to a preset position in the elevator shaft to prevent the entire automatic climbing hanger from moving downward.

[0062] The limiting assembly 40 includes four limiting plates 41 respectively disposed on the outer sides of the square support column 21 . The limiting plates 41 and the outer sides of the square support column 21 form a limiting groove 42 corresponding to the corners of the square column 12 .

[0063] There are four fixing components 400, which are respectively arranged on the corresponding square tube columns 12. The fixing components 400 include an adjustment block 401 detachably arranged on the square tube support column 21 and a clamping block 402 arranged on the adjustment block 401. The square tube support column 21 is provided with a plurality of mounting positions 403 connected to the adjustment block 401 along its length direction. The clamping block 402 is clamped on the corresponding crossbeam 13, so that the entire automatic climbing hanger is clamped in the additional elevator 1 through the fixing components 400. It should be noted that since the two ends of the crossbeam 13 are connected to the corresponding square tube column 12 through the angle steel 14, the clamping block 402 can also be clamped on the angle steel 14.

[0064] In this embodiment, by setting the limit assembly 40, the automatic climbing frame can be made more stable when moving up and down to prevent shaking. At the same time, it can also play a limiting role when the hoisting mechanism 3 is working, so that the entire automatic climbing frame will not shake. The limit plate 41 in the limit assembly 40 is arranged on the outside of the square support column 21 in a long strip shape, and its cross-section is an L-shaped structure. After cooperating with the side of the square support column 21, a right-angled limit groove 42 is formed. The limit groove 42 cooperates with an edge of the square support column 21. Since the square support column 21 has four, the entire support frame assembly 20 can be just limited in the elevator shaft monomer 11.

[0065] In the fixing component 400, the block 402 of the fixing component 400 is detachably arranged on the square tube column 12. When the automatic climbing frame climbs into place, the block 402 is installed at the position of the corresponding square tube column 12. Both ends of the beam 13 are connected to the corresponding square tube column 12 through the angle steel 14, and the block 402 is clamped on the corresponding angle steel 14.

[0066] like Figures 6 to 8 As shown, as a further solution of this embodiment, the lifting mechanism 3 includes a support assembly 30 connected to the support frame assembly 20 and a lifting assembly 300 rotatably connected to the top of the support assembly 30 , and also includes a control assembly 310 for controlling the rotation of the lifting assembly 300 .

[0067] The support assembly 30 includes a support tube 31 disposed in the middle of the support frame assembly 20 and a plurality of second support arm groups 32 and a third support arm group 33. The hoisting assembly 300 is disposed at the top of the support tube 31 and is rotatably connected to the support tube 31. One end of the second support arm group 32 is detachably connected to the lower part of the support tube 31, and the other end of the second support arm group 32 is detachably connected to the corresponding square support column 21; one end of the third support arm group 33 is detachably connected to the upper part of the support tube 31, and the other end of the third support arm group 33 is detachably connected to the corresponding square support column 21. The support tube 31 forms a triangular structure with the second support arm group 32 and the third support arm group 33. The first support arm group 23 has the same structure as the second support arm group 32 and the third support arm group 33, and is composed of a support arm 35 and a support arm 36 that is telescopically matched with the support arm 35.

[0068] In this embodiment, the first support arm group 23 has the same structure as the second support arm group 32 and the third support arm group 33, which can also reduce the types of parts and components and facilitate assembly by the staff. They are all composed of a support arm 35 and a support arm 36, which can be telescopically matched to adapt to elevator shaft units 11 of different sizes, and the support tube 31 and the second support arm group 32 and the third support arm group 33 form a triangular structure, which can be more stable.

[0069] The lifting assembly 300 includes a rotating base 301 rotatably connected to the square support column 21 and a telescopic arm 302 which is arranged on the rotating base 301 and can be telescopically adjusted. It also includes a second electric winch 303 arranged on the rotating base 301 and a hook 304 connected to the lifting rope of the second electric winch 303. A second pulley 305 is provided on the top of the rotating base 301, and a third pulley 306 is provided at the end of the telescopic arm 302. The lifting rope of the second electric winch 303 passes through the second pulley 305 and the third pulley 306 in sequence and is connected to the hook 304.

[0070] The control assembly 310 includes a rotating shaft 311 disposed in the support tube 31 and rotatably matched with the support tube 31, and the bottom of the rotating shaft 311 passes through the support tube 31, and the top of the rotating shaft 311 is connected to the rotating seat 301. The control assembly 310 also includes a rotating disk 312 disposed at the bottom of the rotating shaft 311. In this embodiment, the rotating disk 312 can be provided to adjust the hoisting angle of the hoisting assembly 300, which is convenient for the construction of the staff.

[0071] like Figures 3 to 6 as well as Fig.10 As shown, as a further solution of this embodiment, both ends of the suspension beam 202 are provided with limit fixings 204, and the limit fixings 204 are detachably connected to the cross beam 13 through the provided bolts. When installing the suspension beam 202, the suspension beam 202 and the cross beam 13 are fixed by the limit fixings 204. It should be noted that the limit fixings 204 are U-shaped and can be connected to the suspension beam 202 by welding or bolting, and then fixed to the cross beam 13 by bolts to complete the installation.

[0072] As a further solution of this embodiment, a scale line for identifying the height of the installation position 403 is provided on one side. It should be noted that the installation position 403 may be a bolt hole, and the adjustment block 401 is installed in the corresponding bolt hole by bolts, and by providing the scale line, the entire automatic climbing frame can be easily leveled to prevent the problem that the various adjustment blocks 401 are not on the same horizontal plane. In addition, the scale line is not shown in this application.

[0073] like Figures 1 to 11 As shown, the present invention also provides an elevator shaft assembly method for adding an elevator to an old building, including using the automatic climbing hanger of the elevator 1 added to the old building described above, and the elevator shaft assembly method has the following steps:

[0074] S1, installing the elevator shaft monomer 11 at the bottom layer on the pile 10. Since the elevator shaft monomer 11 at the first layer is directly connected to the pile 10, the elevator shaft monomer 11 at the bottom layer can be directly installed.

[0077] In S4, the automatic climbing hanger climbs upward, and the hanging beam 202 in the automatic climbing hanger is installed between the beams 13 of the elevator shaft unit 11 installed in S3. Then, the first electric winch 201 is started to make the automatic climbing hanger climb to the preset position, and then the fixing assembly 400 is installed at the preset position to cooperate with the corresponding beam 13 to limit the automatic climbing hanger from sliding down in the elevator shaft unit 11.
