[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] like Figure 1As shown, a height positioning structure of a gantry of a handling equipment includes a gantry assembly, a driving assembly, a monitoring assembly and a control assembly. The gantry assembly includes a lifting gantry 1 that can be lifted and lowered on the handling equipment. The driving assembly is located on the handling equipment and is used to drive the lifting gantry 1 to rise or fall. The monitoring assembly includes an encoder 2 for monitoring the horizontal height of the lifting gantry 1. The control assembly includes a control assembly 3 and a control switch 4. The control assembly 3 is electrically connected to the encoder 2 and the driving assembly at the same time, and is used to receive signals from the encoder 2, and can control the driving assembly to drive the lifting gantry 1 to move to a preset height. The control switch 4 is electrically connected to the control assembly 3 and is used to open the control assembly 3. When the encoder 2 obtains the horizontal height information of the lifting gantry 1, the information is transmitted to the control assembly 3. The control assembly 3 determines whether it has reached the preset height. If not, the control switch 4 controls the driving assembly to start, thereby adjusting the height of the lifting gantry 1, thereby improving the height adjustment efficiency of the lifting gantry 1 and improving the adjustment accuracy.

[0019] In this embodiment, the lifting mast 1 is used to install a cargo fork, thereby driving the cargo fork to perform a lifting action.

[0020] Specifically, the control switch 4 also includes a control panel 5, which is electrically connected to the control assembly 3 and is used to transmit a preset height signal to the control assembly 3. In this embodiment, a first preset height, a second preset height and a third preset height that gradually increase can be set on the control panel. When the first preset height, the second preset height or the third preset height is manually selected, the control signal can be transmitted to the control assembly 3, and the control assembly 3 drives the lifting gantry 1 to move to the corresponding position through the driving component.

[0021] In order to achieve the adjustment of the levels, the control component also includes a height adjustment switch 6 and a lowering switch 7. Both the height adjustment switch 6 and the lowering switch 7 are electrically connected to the control screen 5. The height adjustment switch 6 can increase the control instruction from the first preset height to the second preset height, and the lowering switch 7 can lower the control instruction from the second preset height to the first preset height, thereby achieving the adjustment of the control instruction.

[0022] In order to realize the driving of the lifting gantry 1, the driving component includes an oil pump motor 8, an oil pump 9 and a hydraulic valve group 10. The oil pump motor 8 is electrically connected to the control assembly 3. The oil pump 9 is connected to the oil pump motor 8 through an oil suction pipe 11, and the oil pump 9 is connected to the hydraulic valve group 10 through an oil return pipe 12. The hydraulic valve group 10 is connected to the oil pump motor 8 through a pressure oil pipe 13, and is connected to the lifting cylinder of the lifting gantry 1 through a lifting oil pipe 14. When the height of the lifting gantry 1 is lower than the preset height, the oil pump motor 8 passes the hydraulic oil into the hydraulic valve group 10 through the pressure oil pipe 13, and inputs it into the lifting cylinder through the lifting oil pipe 14, thereby driving the lifting gantry 1 to rise. When the height of the lifting gantry 1 is higher than the preset height, the hydraulic valve group 10 switches to the descending mode. At this time, the hydraulic oil refluxes and the lifting gantry 1 descends to the preset height.

[0023] Specifically, the monitoring component also includes a pull rope 15, one end of the pull rope 15 is connected to the lifting gantry 1, and the other end of the pull rope 15 is wound around the encoder 2. The height of the lifting gantry 1 can be obtained by the contraction or expansion distance of the pull rope 15.
