Their convenient and easy-to-use operation makes them an ideal control tool for aerial work vehicles. Operators can achieve different functional controls through different control operation inputs. However, when operating remotely on the ground or in a remote place, due to the long distance between the ground operator and the platform operator, it is easy to cause misoperation due to poor communication, which poses certain safety risks. Summary of the invention

[0038] 3 Security Module DETAILED DESCRIPTION

[0039] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0040] In the prior art, the remote control of the aerial work platform can control the functions of the aerial work platform such as lifting, walking, etc. The remote control signal receiving distance is relatively large, and the aerial work platform can be operated to rise on the ground or on the platform. However, when the remote control is operated on the ground or in a remote place, due to the long distance between the ground operator and the platform operator, it is easy to cause misoperation due to poor communication, which poses certain safety risks.

[0041] In view of this, if Figure 1 and Figure 2 As shown, the inventor of the present application provides a remote control device for an aerial work platform, which includes a remote control placement part 2, a remote control 1, and a safety module 3. The remote control placement part 2 is arranged on the aerial work platform, the remote control 1 is used to control the action of the aerial work platform, and the remote control 1 can be placed on and removed from the remote control placement part 2. The safety module 3 is arranged on the remote control 1 and the remote control placement part 2, that is, part of the structure of the safety module 3 is arranged on the remote control 1, and part of the structure is arranged on the remote control placement part 2. When the remote control 1 is separated from the remote control placement part 2, the state of the safety module 3 can be changed so that the preset control instructions of the remote control 1 are restricted from being executed.

[0042] It can be seen that, since the remote control device for the aerial work platform is additionally provided with a safety module 3, the state of the safety module 3 can change when the remote control 1 is separated from the remote control placement part 2, so that the separation state of the remote control 1 and the remote control placement part 2 can be identified according to the state of the safety module 3. After the separation state of the remote control 1 and the remote control placement part 2 is identified according to the state of the safety module 3, the preset control instructions of the remote control 1 can be restricted to be executed, so that the remote control 1 can only control the aerial work platform to move in a safe direction. In this way, it can be ensured that the remote control is placed in a fixed position so that the remote control can be used to work normally, avoiding the problem of misoperation caused by poor communication due to the long distance between the ground operator and the platform operator, effectively reducing the safety risk of aerial work and achieving safe work.

[0043] It should be noted that the structures of the remote controller 1, the remote controller placement part 2 and the safety module 3 can be various, and the structures of the remote controller 1 and the remote controller placement part 2 can be flexibly set according to actual operation requirements. The control command of the remote controller 1 can be sent to the controller of the aerial work platform through a wired connection or a wireless communication connection, and the controller realizes the final action output result of the aerial work platform according to the control command and the state of the safety module 3. The state of the safety module 3 is different for safety modules 3 with different structures. For example, the safety module 3 can be a switch module, and the state of the safety module 3 is the switch state of the switch module. When the remote controller 1 is separated from the remote controller placement part 2, the switch state of the safety module 3 can be changed, so that the corresponding switch state signal can be obtained. Alternatively, the safety module 3 can also be a positioning module, and the state of the safety module 3 is whether the positioning position of the positioning module is consistent. When the remote controller 1 is located on the remote controller placement part 2, the positioning position of the remote controller 1 is consistent with the positioning position of the remote controller placement part 2, and the state of the safety module 3 is the positioning position consistent state; when the remote controller 1 is separated from the remote controller placement part 2, the positioning position of the remote controller 1 and the positioning position of the remote controller placement part 2 change, and the state of the safety module 3 is changed to the positioning position inconsistent state.

[0044] In addition, the switch module may have various structural forms, such as a proximity switch or a limit switch, etc. The positioning module may include a GPS locator.

[0045] In addition, there are many ways to implement the restricted execution of the preset control instructions of the remote control 1. For example, when the remote control 1 is separated from the remote control placement part 2, the state of the security module 3 changes and can send a priority control instruction to the controller through the bus to restrict the execution of the preset control instruction. Alternatively, when the remote control 1 is separated from the remote control placement part 2, the change in the state of the security module 3 can directly cut off the control circuit for the preset control instruction in the remote control 1. Alternatively, when the remote control 1 is separated from the remote control placement part 2, the change in the state of the security module 3 can directly cut off the control circuit for the preset control instruction in the controller, etc. These different implementation forms should also fall within the scope of protection of the present application. The preset control instructions can be varied. For example, the preset control instructions can be control instructions that will seriously affect the safety of the operation when they are misoperated or when the control instructions are executed incorrectly.

[0046] Furthermore, if Figure 1 As shown, the aerial work platform may include a boom, and the preset control instructions of the remote controller 1 include boom motion control instructions for controlling the boom motion. In this way, when the remote controller 1 is separated from the remote controller placement portion 2, the boom motion control instructions of the remote controller 1 are restricted from being executed, that is, the remote controller 1 cannot realize the remote control function of controlling the boom motion at this time, effectively avoiding the safety problem of misoperation of the boom control during remote control or execution of wrong control instructions due to poor communication.

[0047] Furthermore, if Figure 1 As shown, the aerial work platform may include a turntable, and the preset control instructions of the remote controller 1 may also include a turntable rotation control instruction for controlling the rotation of the turntable. In this way, when the remote controller 1 is separated from the remote controller placement portion 2, the turntable rotation control instruction of the remote controller 1 is restricted from being executed, that is, the remote controller 1 cannot realize the remote control function of controlling the rotation of the turntable at this time, effectively avoiding the safety problem of misoperation of the turntable rotation control during remote control or execution of the wrong control instruction due to poor communication.

[0048] In some specific embodiments, in order to reduce manufacturing and maintenance costs, the security module 3 may be a switch module, and the switch state of the switch module can be changed when the remote controller 1 is separated from the remote controller placement part, so that the preset control instructions of the remote controller 1 are restricted.

[0049] Furthermore, the aerial work platform remote control device may further include a controller, which communicates with the remote control 1 and the switch module respectively. Figure 3 As shown, the controller can be configured as:

[0050] Obtaining a control instruction of remote controller 1, and determining that the control instruction is a preset control instruction;

[0051] Acquire a switch state signal of the switch module and determine that the switch state signal corresponds to a control instruction limit signal;

[0052] Restrict the execution of this control instruction.

[0053] The switch state signal of the switch module includes an on state signal and a off state signal. According to actual operation and design requirements, one of the on state signal and the off state signal may be a control instruction restriction signal, and the other of the on state signal and the off state signal may be a non-control instruction restriction signal. The control instruction restriction signal is a signal that requires restriction on the execution of a preset control instruction, and the non-control instruction restriction signal is a signal that does not require restriction on the execution of a preset control instruction.

[0054] Furthermore, if Figure 3 As shown, the controller can also be configured as:

[0055] Obtaining a control instruction of remote controller 1, and determining that the control instruction is a preset control instruction;

[0056] Acquire a switch state signal of the switch module and determine that the switch state signal corresponds to a non-control instruction limit signal;

[0057] Execute the control instruction.

[0058] In this way, when the controller identifies that the switch state signal of the switch module is not a control instruction limiting signal, it will not affect the normal execution of the control instruction.

[0059] In addition, if Figure 2 As shown, the controller is also configured as:

[0060] Acquire a control instruction of remote controller 1, and determine that the control instruction is a non-preset control instruction;

[0061] Execute the control instruction.

[0062] Among them, the non-preset control instruction may be a control instruction that will not cause serious operational safety problems when it is misoperated or executed incorrectly. The non-preset control instructions may be various, for example, they may include control driving instructions and outrigger lifting instructions. That is, when the controller recognizes that the control instruction of the remote controller 1 is a non-preset control instruction, it will not affect the normal execution of the non-preset control instruction.

[0063] It can be seen that only when the remote controller 1 is placed on the remote controller placement part 2 on the aerial work platform, the boom or turntable can move or rotate in the working direction, otherwise, the aerial work platform can only move or lift the legs. This design can ensure that the operator can use the remote controller 1 to perform the control work of the preset control instructions on the aerial work platform to prevent operating errors. Otherwise, the remote controller 1 can only be used to control the equipment to move in a safe direction, that is, the remote controller 1 can only be used to perform control work that is not a preset control instruction.

[0064] Optionally, the switch module may be a proximity switch and include:

[0065] The proximity switch body is arranged on one of the remote controller 1 and the remote controller placement portion 2;

[0066] A sensing element is disposed on the other of the remote controller 1 and the remote controller placement portion 2;

[0067] Among them, the proximity switch body can change the switch state of the switch module when the proximity sensor is within a preset distance. The proximity switch can switch the switch state without direct mechanical contact with the moving parts, that is, when the proximity switch body is close to the sensor and reaches the action distance, the proximity switch body can be actuated without mechanical contact or any pressure, thereby driving a DC appliance or providing control instructions to a computer device. The proximity switch has the characteristics of a travel switch and a micro switch, and at the same time has sensing performance, reliable operation, stable performance, fast frequency response, long service life, strong anti-interference ability, and has the advantages of being waterproof, shockproof, and corrosion-resistant. For example, the proximity switch can be a passive proximity switch, an eddy current proximity switch, a capacitive proximity switch, a photoelectric proximity switch, an ultrasonic proximity switch, and a microwave proximity switch, and these structural forms should also fall within the scope of protection of this application.

[0068] Specifically, Figure 1As shown, the proximity switch body can be a magnetic switch, and the sensing element is a magnetic element. The remote control placement part 2 can include a placement seat, the sensing element is arranged on the placement seat, and the proximity switch body is arranged on the remote control. The proximity switch body is arranged in alignment with the sensing element when the remote control 1 is placed on the remote control placement part 2. In this way, when the remote control 1 is placed on the remote control placement part 2, when the magnetic switch of the remote control 1 senses external factors with magnetic force such as the magnet of the remote control placement part 2, the magnetic switch is turned on and a magnetic signal is generated. This magnetic signal can be used as a non-control instruction restriction signal and sent to the controller. The controller is used to control the output of the control instruction of the remote control 1 to achieve the final action output. When the remote control 1 is separated from the remote control placement part 2, the magnetic switch is disconnected and there is no magnetic signal. At this time, the remote control 1 can determine that the magnetic switch is disconnected and send a control instruction restriction signal to the controller. The controller correspondingly restricts the execution of the preset control instruction.

[0069] In some other specific embodiments, the switch module may be a limit switch and include:

[0070] The limit switch body is arranged on one of the remote controller 1 and the remote controller placement portion 2;

[0071] The matching piece is arranged on the other of the remote controller 1 and the remote controller placement portion 2, and can contact and match with the limit switch body when the remote controller 1 is placed on the remote controller placement portion 2 to change the switch state.

[0072] Among them, the limit switch can use the collision of the moving parts of the production machinery to make its contacts move to connect or disconnect the control circuit to achieve the purpose of switch control. It has a simple structure, is easy to obtain, and has low purchase and maintenance costs. The structure of the limit switch can be varied, such as direct-acting travel switches, roller travel switches, micro-motion travel switches, etc.

[0073] The second aspect of the present application further provides an aerial work platform, which includes the above-mentioned aerial work platform remote control device. Since the aerial work platform includes the above-mentioned aerial work platform remote control device, it also has all the technical effects brought by the aerial work platform remote control device, so it will not be repeated. Among them, the aerial work platform may include a scissor-type aerial work platform, a trailer-type aerial work platform, a curved arm aerial work platform, a straight arm aerial work platform, an aluminum alloy aerial work platform, a cylinder-type aerial work platform, a spider-type aerial work platform, etc.

[0074] It should be noted that the structural principles of the remote control 1 and the aerial work platform are well known to those skilled in the art, and do not belong to the core improvement part of the present application, so they will not be described here in detail.

[0075] To sum up, the aerial work platform remote control device and the aerial work platform of the present application are equipped with a safety module, and the state of the safety module can change when the remote control is separated from the remote control placement part, thereby being able to identify the separation state of the remote control and the remote control placement part, and being able to limit the preset control instructions of the remote control according to the separation state of the remote control and the remote control placement part, thereby avoiding the problem of misoperation caused by poor communication due to the long distance between the ground operator and the platform operator, effectively reducing the safety risk of aerial work and achieving safe work.
