[0031] The first telescopic support mechanism includes a fixed square tube 8, the outer wall of which is fixedly connected to a vertical sliding rod 4. A sliding square tube 9 is slidably connected to the inner side of the fixed square tube 8 in the left and right directions. A limiting plate 10 is fixedly connected to the left end of the sliding square tube 9, and the limiting plate 10 is located at the left end of the fixed square tube 8.

An elastic reset component is provided between the inclined push plate 11 and the fixed square tube 8.

[0032] The elastic reset assembly includes a first baffle 12, which is fixedly connected to the left end of the inclined push plate 11. The first baffle 12 is located on the upper side of the limiting plate 10. A first spring 13 is fixedly connected to the left side of the first baffle 12. A second baffle 14 is fixedly connected to the left end of the first spring 13. The second baffle 14 is fixedly connected to the outer wall of the fixed square tube 8.

[0033] The drive assembly includes a motor 15, which is located at the bottom of the platform frame 3. The output shaft of the motor 15 is fixedly connected to a worm gear 16, which meshes with a worm wheel 17. A rotating shaft 18 is fixedly connected to the middle of the worm wheel 17. Gears 19 are fixedly connected to both ends of the rotating shaft 18, and each gear 19 meshes with a rack 20. The two racks 20 are fixedly connected to the front and rear C-shaped sleeves 6, respectively.

[0034] A mounting bracket 21 is fixedly connected to the upper side of the motor 15, and the mounting bracket 21 is fixedly set at the bottom of the platform frame 3; the mounting bracket 21 can make the motor 15 firmly fixed at the bottom of the platform frame 3.

[0035] The anchor plate 22 has mounting holes 23, and the anchor plate 22 can be fixedly connected to the floor slab by expansion bolts at the mounting holes 23; the mounting holes 23 enable the anchor plate 22 to be fixed to the floor slab.

[0036] Hinges 24 are provided between the extension plate 2, the anchor plate 22 and the construction platform plate 1; the extension plate 2 and the anchor plate 22 can be flipped relative to the construction platform plate 1 by the installation of the hinges 24.

[0037] Working principle:

[0038] When the device is installed inside the elevator shaft, the anchor plate 22 on the construction platform plate 1 is flipped so that it extends out of the elevator shaft doorway and rests on the floor slab. The anchor plate 22 is then fixed to the floor slab using expansion bolts. Simultaneously, the protruding sliding square tube 9 on the first telescopic support mechanism is placed on the floor slab below, providing support. At the same time, the front, rear, and left-side extension plates 2 are unfolded and diagonally placed against the inner wall of the elevator shaft, so that the platform fills the entire elevator shaft. When construction on the next floor is required, the drive mechanism is activated in the forward direction. The drive mechanism drives the self-climbing frame mechanism to slide upwards, i.e., drives the C-shaped sleeve 6 and connecting rod 7 to slide upwards. When the second telescopic support mechanism on the C-shaped sleeve 6 contacts the bottom of the upper floor slab, it automatically retracts. When the second telescopic support mechanism passes over the upper floor slab, it automatically unfolds and rests on the upper floor slab, thus enabling the self-climbing frame machine to... The structure is hung on the upper floor slab, and the drive mechanism is stopped. Then, the expansion bolts on the anchor plate 22 are unscrewed, and the anchor plate 22 and all the extension plates 2 are retracted. Then, the drive mechanism is started in reverse. The drive mechanism drives the construction platform plate 1, platform frame 3, vertical slide rod 4 and diagonal brace 5 to rise. When the inclined surface of the inclined push plate 11 on the vertical slide rod 4 contacts the bottom of the floor slab, under the reaction force, the inclined push plate 11 pushes the sliding square tube 9 into the fixed square tube 8 and compresses the spring 13 until the sliding square tube 9 completely avoids the floor slab. When the sliding square tube 9 rises to just pass the floor slab, the sliding square tube 9 extends outward to reset under the elastic force of the spring 13 and rests on the floor slab. At the same time, the drive mechanism is stopped. At this time, the construction platform plate 1 has just risen to pass the upper surface of the upper floor slab, thus realizing the automatic climbing of the device.

[0039] In summary, the construction platform, consisting mainly of the construction platform plate 1, platform frame 3, vertical slide rod 4, and diagonal brace 5, can be driven by a drive mechanism to rise through a self-climbing frame mechanism. After rising to the upper floor, the self-climbing frame mechanism can automatically hang on the upper floor slab through a second telescopic support mechanism. Then, the self-climbing frame mechanism drives the construction platform to rise through the drive mechanism, causing the first telescopic support mechanism of the construction platform plate 1 at the bottom of the vertical slide rod 4 to automatically support the lower floor slab, and just rise to the upper surface of the upper floor slab, thus achieving automatic climbing without the need for repeated lifting or repeated installation and disassembly. The extension plate 2 in this device can be extended and leaned against the inner wall of the elevator shaft, so that the construction platform of this device can enclose elevator shafts of various sizes, preventing debris or tools from falling, greatly improving the applicability of the device.

[0040] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the utility model in order to achieve the purpose of the utility model.
