[0028] Four second electric push rods 6 are respectively fixed on the left and right sides of the base 1. When the second electric push rods 6 are started, their output ends are extended and retracted, which can drive the universal wheels 7 to move up and down. The universal wheels 7 gradually move downward, which will lift the base 1 upward, thereby facilitating the movement of the safety lifting device for house construction. After moving to the use position, the universal wheels 7 are put into the fixed frame 5, which can make the base 1 contact with the ground again, thereby effectively improving the overall stability of the device when in use, avoiding the phenomenon of position deviation during high-altitude operations, and thus reducing safety hazards.

[0029] A protective mechanism 2 is arranged above the base 1, and the protective mechanism 2 includes a scissor frame 204, a construction work platform 205 and two servo motors 201. The two servo motors 201 are fixedly connected to the base 1, and the two output shaft ends of each servo motor 201 are fixedly connected to a screw rod 202 rotatably connected to the base 1, and the outer surface of each screw rod 202 is threadedly connected to a slider 203 slidably connected to the base 1.

[0030] The servo motor 201 is installed on the inner bottom wall of the base 1. The two servo motors 201 are electrically connected to the same controller, which can realize the control of the synchronous start of the two servo motors 201. After the servo motor 201 is started, it can drive the screw 202 to rotate forward and reverse in the inner wall of the base 1, thereby driving the two sliders 203 thereon to slide along the inner bottom wall of the base 1, and the two sliders 203 are close to or away from each other.

[0031] Four bearings 3 are embedded in the inner wall of the base 1, and the inner ring of the bearing 3 is fixedly connected to the outer surface of the screw 202.

[0034] When the two sliders 203 are close to each other, the scissor frame 204 can be driven to gradually extend. At the same time, the pin shaft at the hinge between the scissor frame 204 and the slide 206 can slide in the inner wall opened on the slide 206, and then the construction work platform 205 is driven to gradually rise upward through the slide 206, so as to transport construction workers or construction materials to a higher place.

[0035] The front and back sides of the construction work platform 205 are both hinged with a protective plate 208 and two first electric push rods 207 through pins. The protective plate 208 and the first electric push rods 207 are hinged through pins. The front and back sides of the construction work platform 205 are both hinged with a safety door 209 through hinges.

[0036] The construction work platform 205 provides limited support for the first electric push rod 207 and the protective plate 208. The two first electric push rods 207 on the same side are electrically connected to the same controller, so that the two first electric push rods 207 can be controlled to start synchronously. After the first electric push rod 207 is started, its output end is extended and retracted, which can drive the protective plate 208 to rotate with the hinge between the protective plate 208 and the construction work platform 205 as the center, thereby adjusting the angle of the protective plate 208.

[0037] The side of the construction platform 205 is protected by the protective plate 208 to prevent the transported construction materials or construction workers from falling due to accidental shaking of the lifting device, thereby improving the protection performance of the lifting device used in building construction and reducing safety hazards.

[0038] The safety door 209 can be used to protect construction workers who are riding on the safety lifting device used in building construction, so as to avoid the construction workers falling due to accidental shaking of the lifting device, thereby improving the protection performance of the device.

[0039] A battery 8 is fixedly connected to the inner wall of the base 1, the two servo motors 201 are electrically connected to the battery 8, each first electric push rod 207 is electrically connected to the battery 8, and each second electric push rod 6 is electrically connected to the battery 8. The battery 8 can provide power support for the electrical components in the safety lifting device for house construction, so that it can be used without being connected to an external power source at all times, thereby improving convenience during use.

[0040] Example 2

[0042] The outer surface of each limit rod 11 is fixedly connected to a fixing ring 12, and the outer surface of each limit rod 11 is sleeved with a reset spring 13. The second fixed block 10 and the fixing ring 12 are fixedly connected to the reset spring 13. Pulling the limit rod 11 can drive the fixing ring 12 to move, thereby compressing the reset spring 13 to cause it to produce elastic deformation. When the reset spring 13 is not affected by external force, the limit rod 11 can be driven by the fixing ring 12 to return to the initial position, thereby re-realizing the limit fixation of the safety door 209.

[0043] Two safety rings 14 are fixedly connected to one side and the other side of the construction work platform 205. The safety rings 14 can be connected to the safety ropes worn by the construction workers of the building, thereby enhancing safety, providing the construction workers with a second section of safety protection, and better ensuring the safety of the construction workers.

[0044] The components in the drawings of the present invention are only for style reference and are not used as specific size standards. The specific sizes are determined according to the actual requirements of production.

[0045] Working principle: When using the safety lifting device for house construction, first move it to the position where it needs to be used, and then control the two servo motors 201 to start synchronously. After the servo motor 201 is started, it can drive the screw 202 to rotate in the inner wall of the base 1, thereby driving the two sliders 203 thereon to slide along the inner bottom wall of the base 1 and approach each other. After the two sliders 203 approach each other, they can drive the scissor frame 204 to gradually extend, and at the same time, the pin shaft at the hinge between the scissor frame 204 and the slide 206 can slide in the inner wall opened on the slide 206, and then drive the construction work platform 205 to gradually rise through the slide 206, so as to transport the construction workers or construction materials on the construction work platform 205 to At a high place, after the first electric push rod 207 is started, its output end is extended and retracted, which can drive the protective plate 208 to rotate with the hinge of the protective plate 208 and the construction work platform 205 as the center, so as to adjust the angle of the protective plate 208, and protect the side of the construction work platform 205 through the protective plate 208. The safety door 209 can be used to protect the construction workers or construction materials riding on the safety lifting device for house construction. Through the cooperation of the protective plate 208 and the safety door 209, it is possible to avoid the accidental shaking of the lifting device, which may cause the transported construction materials or construction workers to fall, thereby improving the protection performance of the lifting device for house construction and reducing safety hazards.
