However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides an automatic protection device for a hydraulic platform, comprising: a floor platform 1 and a hydraulic lifting platform 2; a protection component 7, the protection component 7 is fixedly connected to the top of the floor platform 1, the protection component 7 comprises a bracket 701, a motor 702 is fixedly connected to the top of the bracket 701, the output end of the motor 702 slides through the bracket 701, a screw rod 703 is fixedly connected to the output end of the motor 702, a first sliding block 704 is threadedly connected to the outer surface of the screw rod 703, a guardrail 707 is fixedly connected to the outer surface of the first sliding block 704, and the lower end surface of the screw rod 703 is rotatably connected to the top of the floor platform 1. The outer surface of the first sliding block 704 is slidably connected to the inner surface of the bracket 701, and a limit rod 705 is fixedly connected between the bracket 701 and the floor platform 1. The limit rod 705 passes through and is slidably connected to the second sliding block 706. The outer surface of the second sliding block 706 is slidably connected to the inner surface of the bracket 701. The second sliding block 706 is fixedly connected to the guardrail 707. The outer surface of the bracket 701 is symmetrically fixedly connected to a support plate 708. A travel switch 709 is fixedly connected to the bottom of the support plate 708. The bottom of the travel switch 709 is in contact with the top of the hydraulic lifting platform 2, and the travel switch 709 is electrically connected to the motor 702.

[0023] The effect achieved by the entire embodiment 1 is that when the hydraulic lifting platform 2 is used, when the hydraulic lifting platform 2 is lifted and moved to the flush position of the floor platform 1, the hydraulic lifting platform 2 will touch the travel switch 709. By installing the travel switches 709 on the upper and lower sides, the travel switch 709 on one side will be triggered when the hydraulic lifting platform 2 is lifted and moved into place. When the hydraulic lifting platform 2 moves away, the travel switch 709 will also be triggered. When the travel switch 709 is triggered for the first time, the guardrail 707 is in the lower position, which plays a safety protection role. The travel switch 709 can be controlled by connecting to the control system when it is triggered. When the motor 702 is running, the motor 702 can drive the screw rod 703 to rotate when it is started. The rotation of the screw rod 703 can drive the first sliding block 704 to move. In conjunction with the setting of the limit rod 705 and the second sliding block 706 on the other side, the guardrail 707 can be driven to move upward synchronously. After the guardrail 707 moves up, the staff can walk into the hydraulic lifting platform 2. After the hydraulic lifting platform 2 moves away, the travel switch 709 is triggered again, and the motor 702 can be started to reverse and drive the guardrail 707 to reset and return to the protection state, thereby achieving the purpose of automatically controlling the up and down movement of the guardrail 707, and having good safety protection performance.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, a first mounting groove 3 is provided on the outer surface of the floor platform 1 close to the hydraulic lifting platform 2, and a receiver 4 is fixedly connected to the bottom of the first mounting groove 3. A second mounting groove 5 is provided on the outer surface of the hydraulic lifting platform 2 close to the floor platform 1, and a beam sensor 6 is fixedly connected to the bottom of the second mounting groove 5. The beam sensor 6 is matched with the receiver 4, and the beam sensor 6 is electrically connected to the motor 702.

[0025] The effect achieved by the entire embodiment 2 is that when the hydraulic lifting platform 2 moves to the position of the floor platform 1 and raises the guardrail 707, during the driving process of the motor 702, through the cooperation of the receiver 4 and the through-beam sensor 6, when the floor platform 1 and the hydraulic lifting platform 2 are in parallel positions, the receiver 4 and the through-beam sensor 6 are in a through-beam state. If the position of the hydraulic lifting platform 2 is offset, the signal of the through-beam sensor 6 will change. At this time, the control system can be used to control the motor 702 to start and lower the guardrail 707. At this time, the guardrail 707 provides shielding protection to avoid danger to the staff when the position of the hydraulic lifting platform 2 deviates, thereby improving the safety protection performance of the device.

[0026] Working principle: When the hydraulic lifting platform 2 is in use, when the hydraulic lifting platform 2 is lifted and moved to the flush position of the floor platform 1, the hydraulic lifting platform 2 will touch the travel switch 709. By installing the travel switches 709 on the upper and lower sides respectively, when the hydraulic lifting platform 2 is lifted and in place, the travel switch 709 on one side will be triggered. When the hydraulic lifting platform 2 moves away, the travel switch 709 will also be triggered. When the travel switch 709 is triggered for the first time, the guardrail 707 is in the lower position, which plays a role in safety protection. The travel switch 709 can control the operation of the motor 702 through the connection of the control system when triggered. The start of the motor 702 can drive the screw rod 703 to rotate. The rotation of the screw rod 703 can drive the first sliding block 704 to move. In conjunction with the setting of the limit rod 705 and the second sliding block 706 on the other side, the guardrail 707 can be driven to move upward synchronously. After the guardrail 707 moves up, the staff can walk When the hydraulic lift 2 enters the hydraulic lift 2, after the hydraulic lift 2 is moved away, the travel switch 709 is triggered again, and the motor 702 can be started to reverse and drive the guardrail 707 to reset to the protection state, that is, the purpose of automatically controlling the up and down movement of the guardrail 707 is achieved, and it has good safety protection performance. When the hydraulic lift 2 moves to the position of the floor platform 1 and raises the guardrail 707, during the driving process of the motor 702, through the cooperation of the receiver 4 and the opposing beam sensor 6, when the floor platform 1 and the hydraulic lift 2 are in parallel positions, the receiver 4 and the opposing beam sensor 6 are in an opposing beam state. If the position of the hydraulic lift 2 is offset, the signal of the opposing beam sensor 6 will change. At this time, the motor 702 can be controlled by the control system to start and lower the guardrail 707. At this time, the guardrail 707 provides shielding protection to avoid danger to the staff when the position of the hydraulic lift 2 deviates, thereby improving the safety protection performance of the device.

The model is selected according to the actual use, so the control method and wiring arrangement of the hydraulic lifting platform 2, motor 702, through-beam sensor 6 and travel switch 709 are no longer explained in detail.
