Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , a multifunctional construction elevator, including a base 1, a working platform 4, an adjusting jack 5, a hydraulic sleeve cylinder 6 and an anti-rotation device. The base 1 is an axisymmetric structure as a whole. At one end of the base 1 corresponding to the connection of the anti-rotation device, there are four fixed anti-rotation blocks 9 distributed axially symmetrically. At one end of the anti-rotation device corresponding to the connection of the base 1, there is an anti-rotation slider one 2 that is connected and matched with the fixed anti-rotation block 9. At the central position of one end of the base 1 corresponding to the connection of the anti-rotation device, a hydraulic sleeve cylinder 6 is welded. At the end of the hydraulic sleeve cylinder 6 facing away from the base 1, a working platform 4 is welded. Adjusting jacks 5 are provided at the four corners of the base 1.

[0024] Furthermore, the main body of the base 1 is a rectangular thick plate surface. At one end of the base 1 corresponding to the connection of the fixed anti-rotation block 9, there are four support rods 11 obliquely arranged and equally distributed in a ring shape. The two ends of the support rods 11 are respectively the main body rectangular thick plate surface and the hydraulic sleeve cylinder 6. And on both sides of the fixed anti-rotation block 9, there is a chute one 10 that is slidably matched with the anti-rotation device. At the position of the base 1 corresponding to the connection of the adjusting jack 5, there is a sliding hole 8 that can be slidably matched with the adjusting jack 5. At one end of the base 1 facing away from the hydraulic sleeve cylinder 6, there is a control module 13. And on the side of the control module 13, there are four rollers 14 distributed axially symmetrically. The fixed anti-rotation block 9 is overall half of the anti-rotation slider one 2, and their structures are the same, which is convenient for telescopic sliding cooperation to ensure the smoothness of the lifting process.

[0025] Furthermore, the working platform 4 consists of three parts, namely the protective frame 20, the top rod of the hydraulic telescopic cylinder 6, and the four anti-rotation sliders III 21 of the anti-rotation device. The main body of the working platform 4 is the protective frame 20 in the shape of a hollow rectangular body. The four sides of the protective frame 20 are vertically perforated, and the top rod of the hydraulic telescopic cylinder 6 is welded at the central part of the protective frame 20. The anti-rotation sliders III 21 of the anti-rotation device are welded around one end of the protective frame 20 corresponding to the hydraulic telescopic cylinder 6. The anti-rotation sliders III 21 welded at one end of the protective frame 20 corresponding to the anti-rotation device are relatively scattered, so that the pressure on its upper part can be well supported.

[0026] Furthermore, the anti-rotation device consists of a fixed anti-rotation block 9, an anti-rotation slider I 2, an anti-rotation slider II 3, and an anti-rotation slider III 21. Among them, the anti-rotation slider I 2 and the anti-rotation slider II 3 have the same structure. The anti-rotation device can effectively prevent the protective frame 20 from rotating, improving the stability of the lifting of the working platform 4 and the safety of construction workers.

[0027] Furthermore, the anti-rotation slider I 2 is integrally in the shape of a cuboid. One end of the anti-rotation slider I 2 corresponding to the connection with the fixed anti-rotation block 9 is provided with a mating groove 15. The two long sides of the mating groove 15 are provided with guide blocks 16 that are symmetrically distributed and slide in cooperation with the chute I 10. And one end of the guide block 16 corresponding to the base 1 is provided with a limit block I 17. The two long sides of the end face of the anti-rotation slider I 2 facing away from the fixed anti-rotation block 9 are provided with two chutes II 18 that are symmetrically distributed and slide in cooperation with the anti-rotation slider II 3. The end of the chute II 18 facing away from the base 1 is provided with a limit block II 19.

[0028] Furthermore, the adjusting jack 5 is integrally in the shape of an L. One end of the adjusting jack 5 corresponding to the connection with the base 1 is provided with a rectangular block that is connected in cooperation with the sliding hole 8. The end of the adjusting jack 5 facing away from the base 1 is provided with a cylindrical support jack block perpendicular to the base 1. The cylindrical support jack block can contact the ground to support the entire construction elevator, increasing the overall bottom support surface of the construction elevator and effectively preventing it from tipping over.

[0029] Working principle: Install the multifunctional construction elevator correctly according to the schematic diagram. Transport the retracted construction elevator to a factory shed with a relatively high and large internal space. Start the adjusting jack 5 so that the four rollers 14 at the bottom of the construction elevator are suspended. Construction workers climb onto the working platform 4 and place the required items and goods on it together. Start the hydraulic motor 12 and the control module 13 to drive the hydraulic telescopic cylinder 6 to start rising step by step, lifting the construction workers until the appropriate height. While the hydraulic telescopic cylinder 6 rises step by step, the four groups of anti-rotation devices symmetrically distributed in a ring around the hydraulic telescopic cylinder 6 start to rise with the hydraulic telescopic cylinder 6, effectively preventing the working platform 4 from shaking and rotating, providing a strong guarantee for the safety and stable work of construction workers.
