A baffle 4 is rotatably connected to the surface of the driving shaft 3. A moving motor 5 is provided inside the baffle 4. A moving screw 6 is inserted at one end of the moving motor 5. A splint 7 is threadedly penetrated through the surface of the moving screw 6. A left wall 8 is provided on the upper surface of the base plate 1, and a protective shaft seat 9 is provided on one side of the left wall 8. A protective shaft 10 is rotatably connected to the internal part of the protective shaft seat 9, and a protective rope 11 is rotatably connected to the surface of the protective shaft 10. An auxiliary shaft seat 12 is provided on the upper surface of the base plate 1, and an auxiliary shaft 13 is rotatably connected to the internal part of the auxiliary shaft seat 12. During use, the driving motor 2 rotates the driving shaft 3 to turn the baffle 4 out, and the moving screw 6 is driven by the moving motor 5 to move the splint 7 to the left, so that the trolley pushed into the elevator can be fixed. When it is no longer needed to be fixed, the driving The motor 2 rotates the driving shaft 3 to reset the baffle 4, which solves the problem that when the trolley is pushed into the elevator, the elevator continues to shake, causing the trolley to move around and thus causing the goods to be transported in the trolley to fall. After the trolley is pushed into the elevator, the clamping plate 7 is moved to the left to fix the wheels of the trolley to reduce the spilling of goods, which greatly enhances the practicability of the equipment. The protection shaft 10 makes the protection rope 11 rotatable, and one end of the protection rope 11 is wrapped around the plate or steel for several turns, and then the other end of the protection rope 11 is connected to the auxiliary shaft 13, and then the protection rope 11 is tightened by rotating the auxiliary shaft 13, which solves the problem that the plate or steel is prone to fall from the elevator to the ground and cause dangerous accidents when being transported in the elevator. After the plate or steel is put into the elevator, the plate or steel is tied and fixed by the protection rope 11 to reduce the risk of its falling, which greatly enhances the protection of the equipment.

[0026] like Figure 5As shown, in this embodiment, an air pump 14 is provided on the upper surface of the base plate 1, an acceleration sensor 15 is provided on one side of the air pump 14, a hose 16 is plugged into one end of the air pump 14, and a protective structure 17 is plugged into the other end of the hose 16, a front wall 18 is provided on the upper surface of the base plate 1, and a protective door 19 is connected to the internal rotation of the front wall 18, a slider 20 is provided on one side of the left wall 8, and a slide rail 21 is slidably connected to one side of the slider 20, and a lifting shaft 22 is connected to the internal rotation of the left wall 8, and a traction rope structure 23 is provided on the surface of the lifting shaft 22, and a lifting motor 24 is plugged into one end of the traction rope structure 23, and a driver 25 is provided on one side of the left wall 8, and the model of the driver 25 is TB6600, which is a professional two-phase stepper motor driver, compatible with Arduino and other multiple main controllers, and can realize the functions of motor forward and reverse control, rotation angle control, etc. Stepper motor driver is an electronic device, usually used as a bridge to connect the controller, power supply and stepper motor. Although the processing performance of the controller is very powerful, its output capacity current is very weak. It requires an intermediate bridge to connect the motor and the main control, and provide sufficient power for the motor at the same time. The driver is like human muscle, and is an important part of the entire system movement. The TB6600 stepper motor driver adopts H-bridge bipolar constant phase current drive, which can be directly powered by 9-42VDC, can choose 7-speed subdivision control, 8-speed current control, and supports up to 4A current output. The signal end is equipped with high-speed photoelectric isolation to prevent signal interference, and supports common cathode and common anode signal input methods. For safety reasons, the driver supports offline retention function, which allows users to debug in the power-on state. Built-in temperature protection and overcurrent protection can adapt to more stringent working environments. The driver is suitable for driving 57, 42 type two-phase and four-phase hybrid stepper motors, and can achieve low vibration, low noise and high speed driving effects. It can be applied to high-precision application fields such as robot control and 3D printing. During use, the acceleration sensor 15 can detect the elevator running speed. When it is detected that the elevator is running too fast, the air pump 14 and the hose 16 are used to quickly inflate the protective structure 17, thereby solving the problem that when people are riding the elevator, the elevator is damaged and causes the elevator to fall quickly, thereby causing injuries to people. The protective structure 17 can be inflated when the elevator falls, and the shock absorption can be performed when the elevator falls to the ground to reduce the injuries to people. The protectiveness of the equipment is greatly enhanced. People can enter the interior of the elevator by rotating the protective door 19. By connecting the traction rope structure 23 with the lifting shaft 22 and driving the traction rope structure 23 by the lifting motor 24, the elevator can be lifted and lowered inside the slide rail 21 through the slider 20.

[0027] How this utility works:

[0028] During use, the driving motor 2 rotates the driving shaft 3 to turn the baffle 4 out, and the moving motor 5 drives the moving screw 6 to move the clamping plate 7 to the left, so that the trolley pushed into the elevator can be fixed. When it is no longer needed to be fixed, the driving motor 2 rotates the driving shaft 3 to reset the baffle 4, which solves the problem that the elevator continues to shake when the trolley is pushed into the elevator, causing the trolley to move around and thus causing the goods to be transported in the trolley to fall. After the trolley is pushed into the elevator, the clamping plate 7 can be moved to the left to fix the wheels of the trolley to reduce the spillage of the goods, which greatly enhances the practicality of the equipment. The protection shaft 10 makes the protection rope 11 rotatable, and one end of the protection rope 11 is wrapped around the plate or steel for several turns, and then one end of the protection rope 11 is connected to the auxiliary shaft 13, and then the protection rope 11 is tightened by rotating the auxiliary shaft 13, which solves the problem that the steel plate falls from the elevator to the ground and causes dangerous accidents when the plate or steel is transported in the elevator. The problem that occurs is solved. After the plate or steel is placed in the elevator, the plate or steel is tied and fixed by the protection rope 11 to reduce its falling risk, which greatly enhances the protection of the equipment. The elevator running speed can be detected by the acceleration sensor 15. When it is detected that the elevator running speed is too fast, the protection structure 17 is quickly inflated by the air pump 14 and the hose 16, which solves the problem that when people are riding the elevator, the elevator is damaged and causes the elevator to fall rapidly, thereby causing injuries to people. The protection structure 17 can be inflated when the elevator falls, and the shock absorption can be performed when the elevator falls to the ground to reduce the injury to people. The protection of the equipment is greatly enhanced. People can enter the interior of the elevator by rotating the protection door 19. By connecting the traction rope structure 23 with the lifting shaft 22 and driving the traction rope structure 23 by the lifting motor 24, the elevator can be lifted and moved inside the slide rail 21 through the slider 20.
