The outer surface of the delivery pipe 208 is fixedly installed with a solenoid valve 209. The pressure sensor 205 is electrically connected to the solenoid valve 209 through a wire. The model of the pressure sensor 205 is MS54XX, and the worker fills the interior of the storage box 207 with nitrogen through high-pressure inflation, so that the nitrogen is compressed inside the storage box 207.

[0025] Specifically, a concave frame 3 is fixedly installed on the front of the guardrail frame 201, and a winding roller 4 is rotatably connected inside the concave frame 3. A rotating motor 5 is arranged on the left side of the concave frame 3. The output end of the power of the rotating motor 5 passes through the concave frame 3 and is fixedly connected to the left end of the winding roller 4. The outer surface of the winding roller 4 is covered with a nylon rope 6.

[0026] Through the above technical scheme, by providing a concave frame 3, a winding roller 4, a rotating motor 5 and a nylon rope 6, the power provided by the rotating motor 5 is used in conjunction with the winding roller 4 to drive the nylon rope 6 to be reeled, thereby facilitating workers to pull objects on the ground to a high place, thereby eliminating the need for workers to frequently lift the elevator body 1, thereby increasing the practicality of the device.

[0027] Specifically, a support platform 7 is fixedly installed on the bottom surface of the rotating motor 5 , and the right side surface of the support platform 7 is fixedly connected to the left side surface of the concave frame 3 .

[0028] Through the above technical solution, by providing the support platform 7, the rotating motor 5 is fixed, so as to avoid the rotating motor 5 from rotating during operation as much as possible, thereby ensuring the working stability of the rotating motor 5.

[0029] Specifically, two groups of telescopic rods 8 are fixedly installed on the upper surface of the guardrail frame 201 , and the telescopic end of each telescopic rod 8 is fixedly connected to the bottom surface of the buffer plate 203 .

[0030] Through the above technical solution, by providing the telescopic rod 8, the moving trajectory of the buffer plate 203 is limited, so as to avoid the buffer plate 203 deviating from the moving trajectory when moving, thereby ensuring the stability of the movement of the buffer plate 203.

[0031] Specifically, a locking block 9 and a locking frame 10 are fixedly mounted on the left side of the guardrail frame 201 , and the locking block 9 is clamped inside the locking frame 10 .

[0032] Through the above technical solution, by providing the locking block 9 and the locking frame 10, the guardrail frame 201 is locked, thereby avoiding the guardrail frame 201 from opening by itself as much as possible, thereby ensuring the stability of the guardrail frame 201.

[0033] Specifically, the right side surface of the material storage box 207 is fixedly connected with a feed pipe 11 , and a valve 12 is fixedly installed on the outer surface of the feed pipe 11 .

[0036] Through the above technical solution, by providing the storage battery 13, electric energy can be provided to the electrical equipment of the device, so that the device is not limited by the length of the wire, and the practicality of the device is further increased.

[0037] The working principle of the utility model is as follows: when in use, the worker first moves the device to the position where construction is required, then the worker climbs to the top of the elevator body 1, and then the worker clamps the lock frame 10 on the lock block 9, thereby locking the guardrail frame 201, and then the worker controls the elevator body 1 to rise through the external controller, so as to facilitate the construction of high-rise buildings, and at the same time uses the power provided by the rotating motor 5 to drive the winding roller 4 to rotate, thereby lowering the nylon rope 6 to the ground, and then the worker fixes the items required for construction on the nylon rope 6, and uses the power provided by the rotating motor 5 to lift the items to a high place, thereby eliminating the need for workers to frequently lift the elevator body 1, thereby increasing the practicality of the device. When high-rise buildings are constructed, When the material on the object accidentally falls onto the buffer plate 203 and the connecting column 204 is not in contact with the pressure sensor 205, the elastic force provided by the buffer spring 202 is used to reduce the impact force on the guardrail frame 201, thereby providing a certain safety protection for the workers inside the guardrail frame 201. When the material on the high building accidentally falls onto the buffer plate 203 and the connecting column 204 is in contact with the pressure sensor 205, the pressure sensor 205 controls the solenoid valve 209 to open through the wire, so that the compressed nitrogen inside the storage box 207 enters the interior of the airbag 206 through the delivery pipe 208, thereby causing the airbag 206 to expand rapidly, thereby further providing safety protection for the workers inside the guardrail frame 201.

[0038] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
