[0007] Furthermore, a non-slip pad is bonded to the bottom of the base plate.

[0008] Furthermore, a guardrail is fixedly connected to the edge of the top of the support plate, and two guard doors are rotatably connected to one side of the guardrail.

[0009] The beneficial effects of the utility model are:

[0010] 1. The support plate is moved by a hydraulic lift to adjust the height of the scaffolding according to demand, so there is no need to replace the working platform, disassemble and assemble it, which improves work efficiency.

[0011] 2. The motor drives the lead screw to rotate, thereby driving the lifting box to move, thereby lifting the materials or tools, making it easier to take the materials or tools, quick and convenient.

[0012] 3. Protect workers through guardrails and protective doors to prevent them from falling off the scaffolding, thereby improving the safety of scaffolding use. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-Figure 3 A liftable scaffolding comprises a base plate 1, a plurality of pillars 4 are welded on the top of the base plate 1, a mounting plate 5 is welded between the plurality of pillars 4, a hydraulic lift 6 is fixed on the top of the mounting plate 5 by bolts, a support plate is fixed on the top of the hydraulic lift 6 by bolts, the support plate is driven to move by the hydraulic lift 6, so as to adjust the height of the scaffolding according to the demand, a first ladder 3 is fixed on the top of the base plate 1 by bolts, one side of the first ladder 3 is fixedly connected to the mounting plate 5, a slide groove 9 is provided on one side of the first ladder 3, a second ladder 10 is slidably inserted in the slide groove 9, the second ladder 10 is fixedly connected to the bottom of the support plate, and the second ladder 10 moves in the slide groove 9 on the first ladder 3 driven by the support plate, so as to be convenient for use at different heights;

[0019] A slide 11 is welded to the top of the base plate 1, and a motor 12 is fixed to the top of the slide 11 by bolts. A screw rod 13 is keyed to the output end of the motor 12. The screw rod 13 is arranged in the slide 11, and a lifting box 14 is threadedly sleeved on the outer wall of the screw rod 13. The screw rod 13 rotates under the drive of the motor 12, thereby driving the lifting box 14 to move, and then lifting the materials or tools, so as to facilitate the taking of the materials or tools.

[0020] A non-slip pad 2 is bonded to the bottom of the base plate 1, so that the scaffolding can be placed stably. A guardrail 7 is fixed to the edge of the top of the support plate by bolts. Two guard doors 8 are rotatably connected to one side of the guardrail 7. The guardrail 7 and the guard door 8 are used to protect the workers and prevent them from falling off the scaffolding.

[0021] Working principle: When in use, first, the support plate is driven to move by the hydraulic lift 6, so as to adjust the height of the scaffolding according to needs. At the same time, the second ladder 10 is moved in the slide groove 9 on the first ladder 3 under the drive of the support plate, so as to facilitate the use of different heights. Then, the staff climbs from the first ladder 3 and the second ladder 10 to the support plate, and then closes the protective door 8, so as to protect the staff through the guardrail 7 and the protective door 8, thereby preventing the staff from falling off the scaffolding, and then, the materials or tools are placed in the lifting box 14, and then the lead screw 13 is rotated under the drive of the motor 12, thereby driving the lifting box 14 to move, and then the materials or tools are lifted up, so as to facilitate the taking of materials or tools.
