[0020] See Figures 1 to 4The shown lifting platform for house construction includes a base 1, pulleys 2 are provided at the four end corners of the bottom of the base 1, a scissor lift 3 is provided on the top of the base 1, a support platform 4 is provided on the top of the scissor lift 3, a mounting groove 5 is provided on the top of the support platform 4, a bidirectional screw 6 is rotatably installed in the mounting groove 5, a drive motor 7 is provided on one side of the support platform 4, the output shaft of the drive motor 7 is connected to the bidirectional screw 6, two sliders 8 are slidably installed in the mounting groove 5, the two sliders 8 are respectively threadedly connected to the bidirectional screw 6 through two sections of opposite direction threads on the bidirectional screw 6, and a guard plate 9 is provided on the top of the two sliders 8. The cross-section of the guard plate 9 is L-shaped, and telescopic rods 10 are provided at the front and rear ends of the opposite sides of the two guard plates 9.

[0021] Furthermore, the scissor lift 3 includes several support rods, hydraulic cylinders and a table top. Several of the support rods are staggered and hinged to each other at the connections. The topmost support rod is hinged to the table top, and the two ends are rotatably connected to the adjacent support rods.

[0022] By extending and retracting the output shaft of the hydraulic cylinder, several support rods can be driven to rotate, thereby adjusting the distance between the base 1 and the support platform 4.

[0023] Furthermore, a plurality of telescopic rods 10 are provided, and the plurality of telescopic rods 10 are equidistantly distributed between the two guard plates 9 . The telescopic rod 10 includes a sleeve 101 and an inner rod 102 , and the sleeve 101 is slidably sleeved on the inner rod 102 .

[0024] When the guard plates 9 on both sides move away from each other, the inner rod 102 slides in the sleeve 101 , so that the telescopic rod 10 can always protect the outside of the support platform 4 .

[0025] Furthermore, there are two mounting grooves 5, and two bidirectional screws 6 corresponding to the mounting grooves 5 are provided. One end of the two bidirectional screws 6 passes through the support platform 4 and is connected to a pulley 11. A belt 12 is provided between the two pulleys 11, and the two pulleys 11 are connected through the belt 12.

[0026] The belt 12 and the pulley 11 can realize the synchronous rotation of the two bidirectional screws 6. Starting the drive motor 7 can drive the two bidirectional screws 6 to rotate synchronously, and then drive the sliders 8 in the two mounting grooves 5 to move at the same time, so as to stably drive the guard plate 9 to move horizontally.

[0027] Furthermore, a protection box 13 is provided on one side of the support platform 4 , and the pulley 11 and the belt 12 are both located inside the protection box 13 .

[0028] A protection box 13 is provided to protect the pulley 11 and the belt 12 .

[0029] Furthermore, the four corners of the base 1 are each provided with an extension plate 14 , and an electric push rod 15 is provided on the top of the extension plate 14 . The output shaft of the electric push rod 15 passes through the extension plate 14 and is connected to a pressure plate 16 .

[0030] When the base 1 moves to a suitable position, the electric push rod 15 is started to extend its output shaft, thereby driving the pressure plate 16 to move downward until it touches the ground, thereby ensuring the stability of the position of the base 1 and ensuring the safety of the staff on the top of the support platform 4.

[0031] Furthermore, a non-slip rubber pad is provided at the bottom of the pressing plate 16 .

[0032] The friction between the pressing plate 16 and the ground is increased by using an anti-skid rubber pad (the anti-skid rubber pad is not shown).

[0033] When the present invention is in use, the pulley 2 is used to move the base 1 to a suitable position. When the support platform 4 is in a lower position, the staff step onto the support platform 4 and protect the staff on the support platform 4 through the guard plate 9 and the telescopic rod 10 to achieve the effect of a guardrail. When the support space at the top of the support platform 4 needs to be extended, the drive motor 7 is started to drive the bidirectional screw 6 to rotate. According to the principle of thread transmission, the sliders 8 on both sides can be driven away from each other, and then the guard plates 9 on both sides can be driven away from each other, and the inner rod 102 slides in the sleeve 101, so that the telescopic rod 10 can always protect the outside of the support platform 4. Through the above arrangement, the support space on the support platform 4 can be extended, and then the support platform 4 is driven to rise upward by the scissor lift 3 so that the staff can perform high-altitude operations.

[0034] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that do not require creative work should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
