Detailed Implementation Methods

[0045] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0046] like Figures 1-11 As shown, this utility model includes an automatic climbing frame for adding an elevator to an old building. The elevator 1 is located outside the old building. The elevator 1 includes a foundation pile 10 and several vertically connected elevator shaft units 11. The several elevator shaft units 11 form an elevator shaft. The elevator shaft unit 11 at the bottom is connected to the foundation pile 10. The elevator shaft unit 11 includes four square tube columns 12 arranged in a vertical direction and several crossbeams 13 that connect two square tube columns 12 on the same side. Both ends of the crossbeams 13 are connected to the corresponding square tube columns 12 by angle steel 14.

[0047] The overall height of the automatic climbing crane is higher than the height of the elevator shaft unit 11, and the automatic climbing crane comprises a climbing mechanism 2, a hoisting mechanism 3 and a limiting and fixing mechanism 4, wherein the climbing mechanism 2 comprises a support frame assembly 20 located in the added elevator 1 and a driving assembly 200 for driving the support frame assembly 20 to move up and down in the added elevator 1. The hoisting mechanism 3 is arranged at the top of the support frame assembly 20 and is used for hoisting each component in the elevator shaft unit 11 for on-site assembly by workers. The limiting and fixing mechanism 4 is arranged on the support frame assembly 20 and is used for limiting the support frame assembly 20 to move up and down in the added elevator 1, and cooperating with the elevator shaft unit 11 to fix the support frame assembly 20 in the added elevator 1 when the support frame assembly 20 is climbed in place, thereby preventing the entire automatic climbing crane from moving downward.

[0048] The added elevator 1 is basically in an old community, and the construction conditions are relatively limited, and the available site is small. Many project sites cannot enter the crane. The added elevator 1 project has developed for nearly ten years, and the added elevator 1 project with good construction conditions has basically been completed. The remaining added elevator 1 projects are basically limited in conditions, and it is difficult to enter the crane, which leads to the difficulty of implementing the added elevator 1 project in some areas, resulting in inconvenience for people in the area to travel.

[0049] The traditional added elevator 1 is assembled by hoisting an entire elevator shaft unit 11 by a crane, and then connecting adjacent elevator shaft units 11. In areas with limited conditions, the crane cannot enter, which makes it difficult to promote the added elevator 1 project in areas with poor construction conditions. Therefore, the automatic climbing crane is arranged to cooperate with the added elevator shaft. After the automatic climbing crane is assembled on site, the automatic climbing crane can climb upward along the added elevator shaft, hoist the components in the elevator shaft unit 11, and directly assemble the elevator shaft on site, solving the problem of limited construction site and reducing the cost of using the crane.

[0050] In the embodiment, the automatic climbing crane is used as follows: first, the first elevator shaft unit 11 is directly connected with the foundation pile 10, so that the staff can directly install the bottommost elevator shaft unit 11. Then the staff installs the entire automatic climbing crane in the elevator shaft unit 11. At this time, the automatic climbing crane can cooperate with the elevator shaft unit 11. The climbing mechanism 2 is started, and the entire automatic climbing crane can climb a distance along the elevator shaft unit 11. Then, after the climbing crane is fixed in the first elevator shaft unit 11 by the limiting and fixing mechanism 4, the second square column 12 in the second layer can be hoisted by the hoisting mechanism 3 in the automatic climbing crane and is connected with the first square column 12 in the first layer. Then, other components are hoisted to complete the installation of the second elevator shaft unit 11. Then, the automatic climbing crane continues to climb to the second elevator shaft unit 11, and the installation of the elevator shaft is completed by repeating the above steps.

[0051] As shown in Figures 2 to 8 the further scheme of the 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 in the vertical direction and spaced apart between the four square support columns 21.

The first support arm groups 23 are detachably connected with the corresponding square support columns 21. In the embodiment, the support assembly 30 mainly includes the four square support columns 21, the plurality of support plates 22, and the plurality of first support arm groups 23. The components are simple and convenient for users to assemble on site.

[0052] The driving assembly 200 includes a first electric winch 201 fixedly arranged on the support plate 22 and a hoisting beam 202 arranged in the elevator shaft unit 11. The driving assembly 200 further includes a first pulley 203 arranged at the bottom of the hoisting beam 202. The two ends of the hoisting beam 202 are detachably connected with the corresponding cross beams 13. The steel wire of the first electric winch 201 is connected with the first pulley 203.

[0053] In the embodiment, the support plate 22 is provided with two support plates. The first electric winch 201 in the driving assembly 200 is fixedly arranged on the lower support plate 22. The two ends of the hoisting beam 202 are arranged between the cross beams 13 in the elevator shaft unit 11. When the automatic climbing crane needs to climb, the hoisting beam 202 is arranged in the elevator shaft unit 11 in the upper layer. Then, the first electric winch 201 is started. The steel wire of the first electric winch 201 is connected with the hoisting beam 202 to hoist the entire automatic climbing crane and move upward. After the hoisting beam 202 is arranged in the elevator shaft unit 11, the support frame assembly 20 is fixed in the elevator shaft unit 11 by the limiting and fixing mechanism 4, so as to limit the downward movement of the entire automatic climbing crane.

[0054] As shown in Figures 2 to 10 As a further scheme of the present embodiment, the limiting and fixing mechanism 4 comprises a limiting assembly 40 for limiting the support frame assembly 20 to move up and down in the built-in elevator 1 only and a fixing assembly 400 for fixing the support frame assembly 20 that has climbed to a preset position in the elevator shaft so as to prevent the whole automatic climbing gantry from moving downward.

The square support column 21 is provided with a plurality of mounting positions 403 connected with the adjusting block 401 along the length direction of the square support column 21, and the clamping block 402 is clamped on the corresponding cross beam 13, so that the whole automatic climbing gantry is clamped in the built-in elevator 1 by the fixing assembly 400. It should be noted that, since the two ends of the cross beam 13 are connected with the corresponding square upright column 12 by the angle steel 14, the clamping block 402 can also be clamped on the angle steel 14.

[0057] In the present embodiment, the automatic climbing gantry can be more stable when moving up and down by arranging the limiting assembly 40, and the shaking of the automatic climbing gantry can be prevented. Meanwhile, the limiting assembly 40 can also play a limiting role when the hoisting mechanism 3 is working, so that the whole automatic climbing gantry will not shake. The limiting plate 41 in the limiting assembly 40 is arranged in a strip shape on the outer side of the square support column 21, and the cross section of the limiting plate 41 is in an L-shaped structure. After the limiting plate 41 is matched with the side surface of the square support column 21, a right-angled limiting groove 42 is formed, and the limiting groove 42 is matched with an edge of the square support column 21. Since the square support column 21 has four edges, the whole support frame assembly 20 can be limited in the elevator shaft 11.

[0058] In the fixing assembly 400, the clamping block 402 of the fixing assembly 400 is detachably arranged on the square upright column 12.
