[0036] BRIEF DESCRIPTION OF DRAWINGS

[0037] 1 remote controller 2 remote controller placing part

[0038] 3 safety module DETAILED DESCRIPTION

[0039] The specific embodiments of the present application will be described in detail below in conjunction with the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0040] ​In the prior art, the remote controller of the aerial work platform can control the lifting, walking and other functions of the aerial work platform. The remote controller signal receiving distance is large, which can operate the aerial work platform on the ground to rise, and can also operate on the platform. However, when remotely operating on the ground or a far place, due to the long distance between the ground operator and the platform operator, misoperation problems caused by poor communication are prone to occur, and there is a certain safety risk.

[0041] Therefore, as shown in Figure 1 and Figure 2 , the inventor of the present application provides an aerial work platform remote controller control device, which comprises a remote controller placing part 2, a remote controller 1 and a safety module 3. The remote controller placing part 2 is arranged on the aerial work platform, the remote controller 1 is used to control the action of the aerial work platform, and the remote controller 1 can be placed on and taken off from the remote controller placing part 2. The safety module 3 is arranged on the remote controller 1 and the remote controller placing part 2, that is, part of the structure of the safety module 3 is arranged on the remote controller 1, and part of the structure is arranged on the remote controller placing part 2. When the remote controller 1 is separated from the remote controller placing part 2, the state of the safety module 3 can be changed, so that the preset control instruction of the remote controller 1 is limited to be executed.

[0042] It can be seen that since the aerial work platform remote controller control device is additionally provided with the safety module 3, the state of the safety module 3 can be changed when the remote controller 1 is separated from the remote controller placing part 2, so that the separation state of the remote controller 1 and the remote controller placing part 2 can be recognized according to the state of the safety module 3. After recognizing the separation state of the remote controller 1 and the remote controller placing part 2 according to the state of the safety module 3, the preset control instruction of the remote controller 1 is limited to be executed, so that the remote controller 1 can only control the aerial work platform to move in a safe direction. In this way, it can be ensured that the remote controller can only be used for normal work when it is placed in a fixed position, and the misoperation problem caused by poor communication due to the long distance between the ground operator and the platform operator can be avoided, the safety risk of aerial work is effectively reduced, and safe operation is realized.

[0043] It should be noted that the structures of the remote control 1, remote control housing 2, and safety module 3 can vary, and the structures of the remote control 1 and remote control housing 2 can be flexibly configured based on actual operational requirements. Control commands from the remote control 1 can be transmitted to the aerial work platform controller via a wired or wireless communication connection. The controller implements the final action output of the aerial work platform based on the control commands and the status of the safety module 3. The status of the safety module 3 varies depending on the structure of the safety module 3. For example, the safety module 3 can be a switch module, in which case the status of the safety module 3 represents the on / off state of the switch module. When the remote control 1 is separated from the remote control housing 2, the on / off state of the safety module 3 can be changed, thereby generating a corresponding on / off state signal. Alternatively, the safety module 3 can be a positioning module, in which case the status of the safety module 3 represents whether the positioning module's positioning position is consistent. When the remote control 1 is on the remote control housing 2, the positioning position of the remote control 1 is consistent with the positioning position of the remote control housing 2, and the status of the safety module 3 is consistent. However, when the remote control 1 is separated from the remote control housing 2, the positioning position of the remote control 1 and the positioning position of the remote control housing 2 change, and the status of the safety module 3 changes to inconsistent.

[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 restriction of 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 it 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 invention. The preset control instructions can be diverse. For example, the preset control instructions can be control instructions that will seriously affect operational safety when they are misoperated or when the control instructions are erroneously executed.

[0046] Further, if Figure 1 As shown, the aerial work platform may include a boom, and the preset control instructions of remote control 1 include boom motion control instructions for controlling boom movement. Thus, when remote control 1 is separated from remote control placement portion 2, the execution of the boom motion control instructions of remote control 1 is restricted. In other words, remote control 1 cannot perform the remote control function of controlling boom movement. This effectively avoids safety issues such as erroneous boom control operation during remote control or the execution of erroneous control instructions due to communication problems.

[0047] Further, as shown in Figure 1 , the aerial work platform can include a turntable, and the preset control instruction of the remote controller 1 can further include a turntable rotation control instruction for controlling 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 limited to be 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 problems of misoperation of the turntable rotation control when remotely controlling or executing incorrect control instructions due to poor communication.

[0048] In some specific embodiments, in order to reduce manufacturing and maintenance costs, the safety module 3 can be a switch module, and when the remote controller 1 is separated from the remote controller placement portion, the switch state of the switch module can be changed so that the preset control instruction of the remote controller 1 is limited.

[0049] Further, the aerial work platform remote controller control device can further include a controller in communication with the remote controller 1 and the switch module. As shown in Figure 3 , the controller can be configured to:

[0050] acquire the control instruction of the remote controller 1 and determine that the control instruction is a preset control instruction;

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

[0052] limit execution of the control instruction.

[0053] Among them, the switch state signal of the switch module includes an on state signal and an off state signal, and according to actual operation and design needs, one of the on state signal and the off state signal can be a control instruction limiting signal, and the other of the on state signal and the off state signal is a non-control instruction limiting signal. The control instruction limiting signal is a signal that needs to limit the execution of the preset control instruction, and the non-control instruction limiting signal is a signal that does not need to limit the execution of the preset control instruction.

[0054] Further, as shown in Figure 3 , the controller can be further configured to:

[0055] acquire the control instruction of the remote controller 1 and determine that the control instruction is a preset control instruction;

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

[0057] execute the control instruction.

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

[0059] Further, as shown in Figure 2 the controller is further configured to:

[0060] obtain the control instruction of the remote controller 1, and determine that the control instruction is a non-pre-set control instruction;

[0061] execute the control instruction.

[0062] The non-pre-set control instruction can be a control instruction that will not cause a serious operation safety problem when a misoperation occurs or when a control instruction is executed by mistake. The non-pre-set control instruction can be various, for example, can include a control travel instruction and a support leg lifting instruction, etc. That is, when the controller identifies that the control instruction of the remote controller 1 is a non-pre-set control instruction, the normal execution of the non-pre-set control instruction will not be affected.

[0063] It can be seen that only when the remote controller 1 is placed on the remote controller placing portion 2 of the aerial work platform, the jib or the turntable can move or rotate in the working direction, otherwise, the aerial work platform can only move or perform support leg lifting. This design can ensure that the operator on the aerial work platform can use the remote controller 1 to perform control work of the pre-set control instruction, prevent operation 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 of the non-pre-set control instruction.

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

[0065] a proximity switch body arranged on one of the remote controller 1 and the remote controller placing portion 2;

[0066] a sensing piece arranged on the other one of the remote controller 1 and the remote controller placing portion 2;

[0067] The proximity switch body can change the switch state of the switch module when the proximity sensing piece is close to the proximity switch body to a preset distance. The proximity switch can switch the switch state without mechanical direct contact with the moving part, that is, when the proximity sensing piece is close to the proximity switch body to the action distance, the proximity switch body can be actuated without mechanical contact and any pressure, thereby driving the direct current appliance or providing a control instruction for the computer device. The proximity switch has the characteristics of travel switch and micro switch, and has the advantages of sensing performance, reliable action, stable performance, fast frequency response, long application life, strong anti-interference ability, and waterproof, shockproof, corrosion-resistant, etc. For example, the proximity switch can be a passive proximity switch, an eddy current proximity switch, a capacitive proximity switch, an optical proximity switch, an ultrasonic proximity switch, and a microwave proximity switch, etc. These structural forms should also belong to the protection scope of the present application.

[0068] Specifically, as shown in Figure 1As shown, the proximity switch body can be a magnetic attraction switch, and the sensing member is a magnetic member. The remote controller placing portion 2 can include a placing seat, and the sensing member is arranged on the placing seat, and the proximity switch body is arranged on the remote controller. The proximity switch body is arranged in position with the sensing member when the remote controller 1 is placed on the remote controller placing portion 2. In this way, when the remote controller 1 is placed on the remote controller placing portion 2, the magnetic attraction switch of the remote controller 1 senses the external factors with magnetic force such as the magnet of the remote controller placing portion 2, the magnetic attraction switch is turned on, and a magnetic attraction signal is generated. The magnetic attraction signal can be used as a non-control instruction limiting signal and is sent to the controller, and the controller is used to control the output of the control instruction of the remote controller 1 to realize the final action output. When the remote controller 1 is separated from the remote controller placing portion 2, the magnetic attraction switch is turned off, and there is no magnetic attraction signal. At this time, the remote controller 1 can determine that the magnetic attraction switch is turned off, and a control instruction limiting signal is sent to the controller, and the controller limits the execution of the preset control instruction.

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

[0070] a limit switch body arranged on one of the remote controller 1 and the remote controller placing portion 2;

[0071] a cooperating member arranged on the other one of the remote controller 1 and the remote controller placing portion 2 and capable of contacting and cooperating with the limit switch body when the remote controller 1 is placed on the remote controller placing portion 2 to change the switch state.

[0072] The limit switch can use the collision of the production mechanical moving parts to make the contact move to realize the on or off of the control circuit, achieve the switch control purpose, and has the advantages of simple structure, easy to obtain, low purchase cost and maintenance cost. The structural form of the limit switch can be various, for example, including a direct-acting travel switch, a roller travel switch, a micro-motion travel switch, etc.

[0073] The second aspect of the present application also provides a high-altitude working platform including the high-altitude working platform remote controller control device. Since the high-altitude working platform includes the high-altitude working platform remote controller control device, it also has all the technical effects brought by the high-altitude working platform remote controller control device, and thus will not be repeated here. The high-altitude working platform can include a scissor-type high-altitude working platform, a trailer-type high-altitude working platform, a boom-type high-altitude working platform, a straight-arm type high-altitude working platform, an aluminum alloy high-altitude working platform, a sleeve cylinder type high-altitude working platform, a spider type high-altitude working platform, etc.

[0074] It should be noted that the structure and principle of the remote controller 1 and the high-altitude working platform are well known to those skilled in the art and do not belong to the core improvement part of the present application, and thus will not be repeated here.

[0075] In summary, the aerial work platform remote controller control device and the aerial work platform of the present application add a safety module, and the state of the safety module can change when the remote controller is separated from the remote controller placement part, so that the separation state of the remote controller and the remote controller placement part can be identified, and the preset control instruction of the remote controller can be limited according to the separation state of the remote controller and the remote controller placement part, thereby avoiding the misoperation problem 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 realizing safe operation.
