[0039] The embodiment of the present application provides an aerial transportation operation equipment, which comprises:

[0043] A sliding sleeve, which is arranged on the equipment platform 10 and cooperates with the lead screw 7.

[0044] By driving the lead screw 7 or the sliding sleeve, the equipment platform 10 can move along the guide rail 8, and generally, the driving of the lead screw 7 or the sliding sleeve (preferably driving the lead screw 7) is in the form of hydraulic driving based on the load characteristics of the equipment platform 10.​​

[0052] Throttle assembly, including n throttle valves 14 and n electrically controlled gate valves 16, the n throttle valves 14 are sequentially connected between the main throttle valve 12 and the hydraulic motor 17, and one electrically controlled gate valve 16 is arranged in parallel on each throttle valve 14, the control end of each electrically controlled gate valve 16 is connected with a corresponding group of inductors, and the default state of the electrically controlled gate valve 16 is an open state, and the inductor switches the state of the corresponding electrically controlled gate valve 16 to a closed state in the triggered state.

[0053] In a specific application, first, the staff controls the pre-control platform 6 to reach a corresponding position according to the position where the equipment platform 10 needs to reach through a pre-control handle; then, the staff starts the hydraulic pump 11 through the control handle, and the equipment platform 10 is driven by the lead screw 7 to move towards the pre-control platform 6; before the equipment platform 10 and the pre-control platform 6 contact, the induction column 5 on the pre-control platform 6 will first trigger the inductor of the equipment platform 10, and every time the induction column 5 triggers an inductor, the electric control gate valve 16 corresponding to the inductor is closed, the corresponding pipeline passage becomes a cut-off state, the pressure oil can only be transmitted through the throttle valve 14 connected in parallel with the electric control gate valve 16, the flow is reduced, and accordingly, the rotating speed of the hydraulic motor 17 is reduced, and the rotating speed of the lead screw 7 is reduced, and the moving speed of the equipment platform 10 is reduced; as the equipment platform 10 and the pre-control platform 6 approach, the multi-stage inductors are triggered in sequence, and the equipment platform 10 is slowed down after multi-stage speed reduction; in actual setting, the throttle passage cross section of the throttle valve 14 corresponding to the last-stage triggered inductor can be adjusted to be extremely small, so that the final speed of the equipment platform 10 tends to zero.

[0054] In an optional embodiment, the aerial transport work equipment further comprises a contact inductor and a contact switch 18.

[0055] The contact inductor is arranged on the equipment platform 10 or the pre-control platform 6, the contact switch 18 is connected to a power supply circuit of the hydraulic pump 11, and the contact inductor is connected with a control end of the contact switch 18, so that the equipment platform 10 can be braked and stopped when the pre-control platform 6 and the equipment platform 10 contact.

[0056] Specifically, the traction assembly comprises a traction motor and a rubber wheel, the rubber wheel is attached to the guide rail 8 or the lead screw 7, and the traction motor is used for driving the rubber wheel to rotate. Figure 1 In actual implementation, the pre-control platform 6 can quickly move along the guide rail 8 under the driving of the traction motor.

[0057] In an optional embodiment, the inductor is a magnetic switch, and the induction column 5 is a magnet.

[0058] In the embodiment of the utility model, the inductor is an infrared grating, and each group of the infrared grating comprises a signal emitter 2 and a signal receiver 3.

[0059] The equipment platform 10 is respectively provided with a corresponding mounting structure at a setting position corresponding to each group of the inductors.

[0060] Each set of mounting structures includes a first protrusion 9 and a second protrusion 4. The signal transmitter 2 and signal receiver 3 of each set of infrared gratings are respectively disposed on the corresponding first protrusion 9 and the corresponding second protrusion 4. The area between the first protrusion 9 and the second protrusion 4 is the sensing area of ​​the corresponding sensor.

[0061] As the device platform 10 and the pre-control platform 6 approach each other along the guide rail 8, the sensing column 5 passes through each of the sensing areas in sequence.

[0062] In an optional implementation, the n throttle valves 14 are of the same model, and based on the adjustment of the n throttle valves 14, the throttling channel cross-sectional areas of the n throttle valves 14 are different from each other. Throttling valves 14 of the same model can be adjusted directly according to the knob settings without the need for complex formula calculations; the n throttle valves 14 can be quickly adjusted according to the required throttling effect; since the throttle valves 14 mainly regulate the flow rate of hydraulic oil, for effectiveness considerations, the throttling channel cross-sectional areas of the n throttle valves 14 are different from each other.

[0063] Furthermore, among the n throttle valves 14, the throttle channel cross-sectional area of ​​the throttle valve 14 that is closer to the hydraulic motor 17 is smaller, thus ensuring the effectiveness of throttling.

[0064] Correspondingly, when the equipment platform 10 and the pre-control platform 6 approach and move along the guide rail 8, the sensors are sorted according to the triggering sequence of the sensors by the sensing column 5, and the n groups of sensors are respectively the first group of sensors, the second group of sensors, ..., the nth group of sensors;

[0065] The n throttle valves 14 are arranged in the direction from the main throttle valve 12 to the hydraulic motor 17, and the n throttle valves 14 are respectively the first throttle valve 14, the second throttle valve 14, ..., the nth throttle valve 14;

[0066] Among them, the a-th group of sensors and the a-th throttle valve 14 have a corresponding relationship, a = 1, 2, ..., n.

[0067] Furthermore, considering that the equipment platform 10 operates bidirectionally on the guide rail 8, in this embodiment of the invention, a pre-control platform 6 is provided on each side of the equipment platform 10 in the direction of movement, and each pre-control platform 6 is equipped with related equipment components; based on the bidirectional movement of the equipment platform 10, a two-position four-way mechanical valve 13 is added to the drive control structure of the hydraulic motor 17 for switching the supply of hydraulic oil, thereby controlling the direction switching of the hydraulic motor 17; similarly, in order to ensure that the multi-stage throttle valve 14 deceleration structure adopted in this embodiment of the invention can maintain normal operation after the hydraulic motor 17 switches, on the one hand, in the bidirectional pipeline passage of the hydraulic motor 17, each Each pipeline is equipped with n sets of throttle valves 14 and electrically controlled gate valves 16 connected in parallel. In addition, since the parallel structure of throttle valves 14 and electrically controlled gate valves 16 mainly acts on the oil input side of the hydraulic motor 17, in order to prevent the oil output side of the hydraulic motor 17 from being affected by the throttle valves 14, each throttle valve 14 of the entire device is also connected in parallel with a check valve 15. The oil in the check valve 15 is allowed to flow in the direction from the hydraulic motor 17 to the hydraulic pump 11. When the pipeline where the throttle valve 14 is located is the oil output side of the hydraulic motor 17, the hydraulic oil can flow back to the hydraulic pump 11 directly through the check valve 15 without being controlled by the throttle valve 14 and the corresponding electrically controlled gate valve 16.

[0068] In practice, the aerial transport equipment also includes a robotic arm 1, which is mounted on the bottom surface of the equipment platform 10. In practical applications, the end effector of the control and transport equipment can be changed according to operational requirements.

[0069] In summary, this utility model provides an aerial transport operation device. Based on existing equipment, a pre-control platform is added, changing the operator's focus from the equipment platform to the pre-control platform. Due to its lower load and faster operating speed, the pre-control platform saves operator time and reduces labor costs. After startup, the equipment platform automatically moves towards the pre-control platform. Based on improvements to the hydraulic motor drive system, multi-stage deceleration of the hydraulic motor is achieved through multi-stage triggering of the induction column and sensors. This allows the equipment platform to automatically complete multi-stage braking operations as it approaches the pre-control platform, preventing impact on other structures and effectively improving the durability of the entire aerial transport operation device. The aerial transport operation device provided by this utility model can be well applied to the retrofitting of old gantry cranes, achieving semi-automatic control of gantry cranes at low cost and offering good economic benefits.

Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model.
