[0018] The following is combined with Figure 1 To the attached Figure 3 The principles and features of the present invention are described, and the examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0019] A lift with rapidly removable wiring comprises a lifting platform 1, a lifting frame 2, a platform base 3, a control box 4, a quick-connect module 8, movable wheels 9, and a hydraulic system. The upper end of the lifting frame 2 is movably connected to the lifting platform 1, while the lower end of the lifting frame 2 is movably connected to the platform base 3. The control box 4 is connected to the quick-connect module 8 via a hydraulic hose. The quick-connect module 8 is located on the platform base 3 or the lifting platform 1. Several movable wheels 9 are symmetrically arranged on the lower surface of the lifting platform 1. The height of the movable wheels 9 ensures that the lift can be moved by the movable wheels 9 after recovery without interference from the platform base 3.

[0020] Lifting frame 2 comprises a cross-connected rod 1 5 and a cross-connected rod 2 6, with a lifting cylinder 7 positioned between them. Specifically, rod 1 5 and rod 2 6 are hinged at their respective midpoints. To ensure better synchronization and load-bearing capacity, in one embodiment, two sets of lifting frames 2 are provided, with a lifting cylinder 7 positioned between rod 1 5 and rod 2 6 in each set.

[0021] The hydraulic system includes a lifting valve block 10, a recovery valve block 11, and an oil tank disposed within the control box 4. The lifting valve block 10 and the recovery valve block 11 are disposed within the quick-connect module 8. The lifting valve block 10 communicates with the rodless chamber of the lifting cylinder 7, while the recovery valve block 11 communicates with the rod-loaded chamber of the lifting cylinder 7. A quick connector 12 is disposed within the lifting valve block 10, and a quick connector 2 13 is disposed within the recovery valve block 11. The oil tank is connected to quick connectors 12 and 13 via a hydraulic hose. A plug is disposed at the end of the hydraulic hose for connecting quick connectors 12 and 13. Quick connector 12 communicates with the rodless chamber of the lifting cylinder 7. Quick connector 2 13 is connected to check valve 14 and check valve 2 15, respectively. Check valve 14 is also connected to a relief valve 16, which communicates with the rod-loaded chamber of the lifting cylinder 7. After the platform base 3 is recovered, the pressure generated by its own weight on the rod chamber of the lifting cylinder 7 is less than the set pressure of the relief valve 16. In one embodiment, the set pressure of the relief valve 16 is 10 MPa.

[0022] The working process of the lift with quick detachable lines of the utility model is as follows:

[0023] When lifting is required, hydraulic oil flows from the oil tank through quick connector 12 of lift valve block 10 and enters the rodless chamber of lift cylinder 7. The pressure in the rodless chamber increases, causing the cylinder to extend. The hydraulic oil in the rod chamber is then pressurized and flows back into recovery valve block 11. At this point, the oil circuit pressure exceeds the set pressure of relief valve 16, and the hydraulic oil passes through relief valve 16 and then returns to the oil tank through check valve 14 and quick connector 2 13. This completes the lifting action.

[0024] When recovery and movement are required, the hydraulic oil flows from the oil tank through the quick connector 2 13 of the recovery valve block 11 into the rod chamber of the lifting cylinder 7. The pressure in the rod chamber increases, causing the cylinder to retract, and the hydraulic oil in the rodless chamber is pressurized and flows back to the lifting valve block 10 and then returns to the oil tank. During the recovery process, the moving wheel 9 gradually approaches the ground. When the moving wheel 9 touches the ground, the platform base 3 continues to rise until it is fully recovered. At this time, the moving wheel 9 can play a supporting and moving role. After full recovery, the platform base 3 generates pressure on the rod chamber of the lifting cylinder 7 due to its own weight. This pressure is less than the set pressure of the relief valve 16. Therefore, the oil circuit pressure from the quick connector 2 13 to the relief valve 16 is 0Mpa. At this time, the plug of the hydraulic hose can be unplugged to achieve rapid separation of the control box 4, making the movement of the entire lift more convenient and flexible.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
