[0024] The specific embodiments of this utility model will now be described with reference to the accompanying drawings.

[0025] like Figure 1 , Figure 2 As shown, this utility model is an adjustable machine room-less elevator installation and operation platform. Its structure mainly includes an external fixed upright 1, a horizontal adjustment support rod 2, a vertical adjustment rod 3, a first horizontal connecting rod 4, a second horizontal connecting rod 5, a third horizontal connecting rod 6, a side adjustment rod 8, a fourth horizontal rod, a first platform pedal 9, a second platform pedal 10, and a third platform pedal 11.

[0026] There are two external fixed poles 1, which are set on both sides outside the elevator entrance 19. The lower end of the external fixed pole 1 is connected to the upper surface of the floor slab below the elevator entrance 19, and the upper end of the external fixed pole 1 is connected to the side wall of the upper shaft 18 of the elevator entrance 19, thereby fixing the external fixed pole 1 to the main structure of the building and making it the main load-bearing structure.

[0027] Specifically, a base 1-1 is provided at the lower end of the external fixed upright 1, and bolts are threaded through the base 1-1 to fix the base 1-1 to the upper surface of the floor slab. The upper end of the external fixed upright 1 is attached to the outer wall of the upper shaft 18 of the elevator entrance 19, and the upper end of each external fixed upright 1 is fixed to the outer wall of the shaft 18 by at least one bolt.

[0028] A horizontal adjustment support rod 2 is provided at the lower end of each external fixed upright 1. The horizontal adjustment support rod 2 extends inward into the elevator shaft 18. Several adjustment holes 17 are provided at both ends of the horizontal adjustment support rod 2. The horizontal adjustment support rod 2 is connected to the lower end of the external fixed upright 1 through the adjustment hole 17 at the outer end. A bolt passes through one of the adjustment holes 17 on the external fixed upright 1 and the horizontal adjustment support rod 2. Through the above adjustable connection, the length of the horizontal adjustment support rod 2 extending into the elevator shaft 18 can be adjusted, so that the inner end of the horizontal adjustment support rod 2 contacts the inner wall of the elevator shaft. On the one hand, the contact point between the horizontal adjustment support rod 2 and the inner wall of the shaft 18 improves the stability and safety of the operating platform. On the other hand, it can prevent the formation of gaps between the inner end of the operating platform and the inner wall of the shaft 18, thus improving safety.

[0029] A first platform step 9 is set between the two horizontal adjustment support rods 2. The first platform step 9 is attached to the two horizontal adjustment support rods 2, and construction workers can stand on the first platform step 9 to carry out construction.

[0030] There are two vertical adjusting rods 3, located at the upper part of the inner ends of the two horizontal adjusting support rods 2 respectively. The adjusting hole 17 at the lower end of the vertical adjusting rod 3 is connected to the adjusting hole 17 at the inner end of the horizontal adjusting support rod 2 by bolts. There are two first horizontal connecting rods 4, located at the upper part of the two external fixed uprights 1 respectively. The outer end of the first horizontal connecting rod 4 is connected to the external fixed upright 1 by bolts, and the inner end is connected to the adjusting hole 17 at the upper part of the vertical adjusting rod 3 by bolts. Since several adjusting holes 17 are provided at the upper and lower ends of the vertical adjusting rod 3, the height position of the vertical adjusting rod 3 can be adjusted.

[0031] Several vertical side adjustment rods 8 are distributed along the length of each first horizontal connecting rod 4. Several adjustment holes 17 are provided on the side adjustment rods 8. The first horizontal connecting rod 4 is connected to the adjustment holes 17 of the side adjustment rods 8 by bolts. The tops of the several side adjustment rods 8 and the vertical adjustment rods 3 are connected to the second horizontal connecting rod 5. The middle of the several side adjustment rods 8 is connected to the third horizontal connecting rod 6. The end of the third horizontal connecting rod 6 is connected to the vertical adjustment rod 3. The heights of the side adjustment rods 8 and the vertical adjustment rod 3 can be adjusted together, thereby adjusting the heights of the second horizontal connecting rod 5 and the third horizontal connecting rod 6.

[0032] A second platform step 10 is provided between the two first horizontal connecting rods 4, and construction workers can use ladders or other tools to climb onto the second platform step 10 to carry out operations.

[0033] A third platform step 11 is provided between the two third horizontal connecting rods 6, so the height of the third platform step 11 can be adjusted by the side adjustment rod 8 and the vertical adjustment rod 3, so that the construction personnel can reach the appropriate height for installation.

[0034] A first inclined support 12 is connected between the lower end of the external fixed upright 1 and the inner end of the first horizontal connecting rod 4. The first inclined support 12 forms a stable right-angled triangle structure with the external fixed upright 1, the first horizontal connecting rod 4 and the first inclined support 12, thereby ensuring the stability of the second platform pedal 10.

[0035] Several adjustment holes 17 are provided in the middle of the vertical adjustment rod 3. A fourth horizontal connecting rod 7 is provided between the outer fixed upright 1 and the vertical adjustment rod 3. The outer end of the fourth horizontal connecting rod 7 is connected to the middle of the outer fixed upright 1 by bolts, and the inner end of the fourth horizontal connecting rod 7 is connected to the adjustment hole 17 in the middle of the vertical adjustment rod 3 by bolts. The connection of the fourth horizontal rod is not affected when the vertical adjustment rod 3 is adjusted up and down through the adjustment hole 17.

[0036] A second inclined support 13 is provided between the inner end of the horizontal adjustment support rod 2 and the outer end of the fourth horizontal connecting rod 7. The external fixed upright rod 1, the horizontal adjustment support rod 2 and the second inclined support 13 form a structurally stable right-angled triangle structure. At the same time, the fourth horizontal connecting rod 7, the second inclined support 13 and the vertical adjustment rod 3 also form a structurally stable right-angled triangle structure, thereby ensuring the stability of the first platform pedal 9.

[0037] To further improve the overall structural strength and stability of the operating platform, a first transverse connecting rod 14 is provided between the lower ends of the two vertical adjusting rods 3, and a second transverse connecting rod 15 is provided between the middle parts of the two vertical adjusting rods 3. Furthermore, a third transverse connecting rod 16 is provided between the upper parts of the two external fixed uprights 1.

[0038] Since the first transverse link 14 and the second transverse link 15 are located at the inner end of the operating platform, and the third transverse link 16 is located at the upper part of the outer end of the operating platform, they will not affect the construction personnel passing through the elevator entrance 19.

[0039] Construction workers can install the elevator on three platforms at different heights: the first platform step 9, the second platform step 10, and the third platform step 11. The height of the third platform step 11 is adjustable to meet the actual needs of the elevator installation process.

[0040] In this invention, each member can be made of I-beams, channel steel, or angle steel as needed.

[0041] This invention can form a stable and solid installation and operation platform, eliminating the need to erect scaffolding from the bottom of the elevator shaft, which can greatly improve construction efficiency and ensure safety during the installation and construction process.

[0042] Meanwhile, this utility model is easy to disassemble and relocate, and the extension length of the horizontal adjustment support rod 2 can be adjusted, so that it can be applied to elevator shafts 18 of different sizes.
