[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figures 1 to 2A protective mechanical structure for a construction lifting platform includes a cage 1. Two side plates 2 are fixedly connected to the inner wall of one side of the cage 1, and a railing 3 is rotatably connected between the two side plates 2. Two mounting plates 4 are fixedly connected to the inner side of the cage 1, and a support plate 5 for supporting the railing 3 is fixedly connected between the two mounting plates 4. An adjustment mechanism is installed on the inner wall of the cage 1. A wire rope 6 is fixedly connected to the upper surface of the railing 3. The wire rope 6 passes through the adjustment mechanism and is fixedly connected to a drive assembly. The drive assembly is fixedly connected to the upper end of the inner wall of the cage 1.

[0018] In use, the protective mechanical structure of the construction hoisting platform of this utility model allows the operator in the control room to control the drive components after a concrete transport vehicle enters the cage 1. This releases the wire rope 6, causing the guardrail 3 to rotate downwards under its own weight until its front end rests against the support plate 5. The guardrail 3 effectively intercepts the concrete transport vehicle, preventing it from continuing its journey and exiting through the front or rear doors of the cage 1. There are two guardrails 3, one at the front and one at the rear of the vehicle, respectively. When the front door is open, the barrier 3 at the rear door is lowered. This way, when a vehicle enters through the front door, the barrier 3 at the rear door blocks the vehicle. After the vehicle enters, the other barrier 3 is also lowered, thus blocking both ends of the vehicle. After the cage 1 moves, when the vehicle exits, only the door and barrier 3 in the exit direction need to be pulled up. When the barrier 3 is not needed, it can also be pulled up, with its upper end attached to the roller 10 on the adjusting mechanism, so that the barrier 3 is at an inclined angle. This allows it to rotate downwards on its own without applying force. If it encounters an obstruction, the staff can push it to promote normal rotation.

[0019] like Figure 2 As shown, the railing 3 is made of stainless steel and has several cavities 7 inside.

[0020] Specifically, stainless steel has high strength, and the cavity 7 is designed to reduce its weight while meeting strength requirements, thereby reducing the load on the drive components.

[0021] like Figure 1 As shown, a foam pad 8 is fitted on the outer side of the railing 3.

[0022] Specifically, when a worker's head hits the railing 3, the foam pad 8 can cushion the impact and reduce pain. Furthermore, when the railing 3 is lowered, the worker can sit on it to rest, as it is soft and more comfortable.

[0023] like Figure 1As shown, the adjustment mechanism includes two rotating blocks 9 fixedly connected to the inner wall of the cage 1, a first roller 10 rotatably connected between the two rotating blocks 9, and a second roller 11 rotatably connected to the inner wall of the cage 1. The first roller 10 and the second roller 11 are perpendicular to each other.

[0024] Specifically, one end of the wire rope 6 is fixedly connected to the railing 3, and the other end passes through the first roller 10 and the second roller 11 in sequence before being fixedly connected to the winding drum 14 on the drive assembly.

[0025] like Figure 1 As shown, the drive assembly includes a driver 12 fixedly connected to the inner wall of the cage 1, a rotating shaft 13 fixedly connected to the output end of the driver 12, and a winding drum 14 fixedly connected to the front end of the rotating shaft 13.

[0026] Specifically, when it is necessary to lower the railing 3, the operator in the control room presses the button to make the driver 12 run. The driver 12 makes the rotating shaft 13 and the winding drum 14 rotate, thereby releasing the wire rope 6. The railing 3 is in an inclined state and can rotate by its own weight until the front end of the railing 3 touches the support plate 5. The railing 3 can be retracted by repeating the operation.

[0027] like Figure 1 As shown, the driver 12 is a forward and reverse rotating motor.

[0028] Specifically, the forward and reverse motor can control the rotating shaft 13 and the winding drum 14 to rotate forward or reverse, thereby releasing or winding the wire rope 6.

[0029] like Figure 2 As shown, a zone stop line 15 is set on the ground inside the cage 1.

[0030] Specifically, the area stop line 15 can remind vehicles transporting concrete and other building materials to park inside this area, so as not to affect the rotation of the railing 3 and thus ensure the protective effect of the railing 3.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
