Description

Technical Field

[0001] The utility model belongs to the technical field of engineering equipment accessories, in particular to a control device which can facilitate mode switching. Background Art

[0002] With the development of network communication technology, many engineering equipment can now be remotely operated. Remote operation can not only improve the working environment of operators, but also avoid some accidents that may occur during the work process.

[0003] For example, in the process of manual remote operation of loaders, excavators and other equipment, some electronic control components are needed to control the corresponding operating handles, such as shifting gears, braking and other operations. However, some current electronic control components are directly connected to the control handles. Therefore, when manual operation is required, due to some limitations of the electronic control components, both hands cannot effectively operate the handles. Therefore, the control devices of some operating handles currently used limit the manual control method of the operating handles and cannot meet actual operating needs. Therefore, a control device that can achieve manual and automatic control is needed. Utility Model Content

[0004] In view of the above problems, the utility model provides a control device which can facilitate mode switching, and is used to solve the problem that the automatic control devices on existing loaders and excavators cannot take into account both manual and automatic operation modes at the same time, which limits the manual control operation handle.

[0005] To achieve the above object, the technical solution adopted by the utility model is: a control device that can facilitate mode switching, including a telescopic element, the telescopic end of the telescopic element is connected to a first pull wire connected to a control handle;

[0006] A reciprocating connection seat is fixedly connected to the telescopic element, one end of which is fixedly connected to a second pull wire for manual control, and a locking device is provided on the connection seat to fix and lock the position of the connection seat when the telescopic element is working;

[0007] A sliding seat is fixedly arranged at the bottom of the connecting seat, and the sliding seat is slidably arranged on the guide rail.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: automatic control of the operating handle is achieved through the arrangement of the telescopic element, and the connected first pull wire is simultaneously connected to the second pull wire for manual control, so that during manual control, the telescopic element can act as an intermediate transition section, synchronously pulling the telescopic element and the first pull wire to move together, and when the telescopic element is working for automatic control, the locking device can lock and fix the position of the connecting seat so that the second pull wire will not be pulled in the reverse direction, thereby preventing the telescopic element of the electric control element from affecting the manual control, and thus realizing the switching between manual and automatic control modes.

[0009] As a further improvement of the above solution, the guide rail is fixedly arranged on the base, and both ends of the base are bent and tilted upwards;

[0010] The first pull wire and the second pull wire pass through the base respectively.

[0011] The technical effect of the above improvement is: as a base, it can provide support force for the first pull wire, the second pull wire and the guide rail.

[0012] As a further improvement of the above solution, the locking device includes a telescopic component fixedly arranged with the connecting seat, and a limiting member that can be buckled with the output end of the telescopic component is arranged below the telescopic component;

[0013] The limiting member is fixed on the base.

[0014] As a further improvement of the above solution, the telescopic assembly includes an electromagnet, a telescopic rod is movably provided at the lower end of the electromagnet, and a first spring is provided between the electromagnet and the telescopic rod;

[0015] When the telescopic rod is powered on, the telescopic rod is sucked upward and retracted, and the telescopic rod can be inserted into the limiting member.

[0016] The technical effect of the above improvement is: by energizing the electromagnet, the electromagnet can adsorb the telescopic rod upward, so that the telescopic rod can be moved out of the limiting piece. At this time, the telescopic rod and the limiting piece lose their mutual limiting effect. Therefore, when the control handle is manually pulled by the second pull wire, the connecting seat and the telescopic element can be automatically and synchronously pulled together as a transition section to interact and realize the transmission of pulling force. When the electromagnet is powered off and the positions of the telescopic rod and the limiting piece are aligned, the telescopic rod can be driven into the limiting piece under the elastic force of the first spring, and the position of the connecting seat will be restricted. When the telescopic element starts to automatically control the handle, the positions of the telescopic element and the connecting seat are restricted, and the second pull wire will not be pulled in the opposite direction. Therefore, the manual control will not be affected during the normal automatic control of the handle.

[0017] As a further improvement of the above scheme, a fixed clamping seat is fixedly arranged on the connecting seat, and a movable clamping seat is slidably arranged on the fixed clamping seat. The interval between the movable clamping seat and the fixed clamping seat forms a clamping cavity for the second pull wire to pass through, and the clamping cavity and the end of the second pull wire are mutually clamped.

[0018] As a further improvement of the above solution, a limiting platform is fixedly provided at the bottom of the movable clamping seat, and a second spring for pushing the movable clamping seat to move downward is provided between the limiting platform and the fixed clamping seat.

[0019] The technical effect of the above-mentioned improvement is: by setting a fixed clamping seat and a movable clamping seat, the end of the second pull wire can be clamped, and under the push of the second spring, the clamping force between the movable clamping seat and the fixed clamping seat can be increased to prevent the second pull wire from escaping from the clamping cavity. When replacing the second pull wire, you only need to pull the movable clamping seat upwards to replace the second pull wire, and the replacement efficiency is higher.

[0020] The technical effect of the above improvement is: a device for detecting the movable displacement of the telescopic element is also provided;

[0021] The connecting seat is also provided with a device for detecting the displacement of the extended end of the telescopic element.

[0022] The technical effect of the above-mentioned improvement is: through the setting, the displacement of the activity of the telescopic element can be detected. Therefore, during manual control, the position of the telescopic element can be judged by the detected displacement, and the device arranged on the telescopic element can detect the length of the extended end of the telescopic element. Therefore, the displacement of the pulling of the first pull wire can be known based on the detected distance, so that step-by-step regulation can be achieved when adjusting the gear position and other operations.

[0023] As a further improvement of the above solution, a cover plate is fixedly provided on the top of the base.

[0024] The technical effect of the above improvement is that the cover plate is mainly used to protect the components arranged on the base to avoid damage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solution, the utility model is described in detail below in conjunction with embodiments. The description in this section is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0031] like Figure 1-4 As shown, the specific scheme of this embodiment is: a control device that can facilitate mode switching, including a telescopic element 10. In this embodiment, the telescopic element 10 is specifically an electric push rod. The telescopic end of the telescopic element 10 is connected to a first pull wire 11 connected to the control handle, and the first pull wire 11 is a steel rope;

[0032] A reciprocating connection seat 12 is fixedly connected to the telescopic element 10, and one end of the connection seat 12 is fixedly connected to a second pull wire 14 for manual control. The second pull wire 14 is also a steel rope. A locking device is provided on the connection seat 12 to fix and lock the position of the connection seat 12 when the telescopic element 10 is working. Specifically, when the manual mode is used to control the control handle of engineering equipment such as an excavator or a loader, the locking device does not work and does not produce a locking effect. At this time, when the second pull wire 14 is manually pulled, the telescopic element 10 and the connection seat 12 can be synchronously driven to move together with the first pull wire 11. Therefore, the telescopic element 10 and the connection seat 12 are equivalent to a transition of pulling the first pull wire 11. When the automatic control mode is adopted, the locking device works to fix the position of the connection seat 12, so that the telescopic element 10 will not move when working, and will not pull the second pull wire 14 to move, so that the extension and contraction of the telescopic element 10 can automatically pull the first pull wire 11 to move, thereby controlling the handle;

[0033] A sliding seat 13 is fixedly disposed at the bottom of the connecting seat 12 , and the sliding seat 13 is slidably disposed on the guide rail 15 .

[0034] like Figure 1As shown, as a preferred embodiment of the above embodiment, the guide rail 15 is fixedly arranged on the base 16, and the two ends of the base 16 are bent upward, and the first pull wire 11 and the second pull wire 14 pass through the base 16 and the two ends of the base 16 that are tilted upward respectively; it is mainly used for the installation of the first pull wire 11 and the second pull wire 14, and at the same time, the control connection wires of the telescopic element 10 and the locking device also pass through the two ends of the tilted base 16.

[0035] like Figure 2 As shown, as a preferred embodiment of the above embodiment, the locking device includes a telescopic component 17 fixedly arranged with the connecting seat 12. In this embodiment, the telescopic component 17 includes an electromagnet 171, and a telescopic rod 172 is movably arranged at the lower end of the electromagnet 171. A first spring 173 is arranged between the electromagnet 171 and the telescopic rod 172. When the telescopic rod 172 is energized, the telescopic rod 172 is sucked and retracted upward. The first spring 173 provides an elastic force to push the telescopic rod 172 to extend downward. A limiting member 18 that can be mutually buckled with the output end of the telescopic component 17 is arranged below the telescopic component 17. Specifically, the limiting member 18 is a groove with an opening facing upward. The limiting platform, the telescopic rod 172 can be inserted into the groove of the limiting member 18; the limiting member 18 is fixed on the base 16, so under normal circumstances, the positions of the telescopic rod 172 and the limiting member 18 are aligned with each other, and the electromagnet 171 is not energized, the telescopic rod 172 extends into the limiting member 18, that is, the position of the connecting seat 12 can be fixed, so that the connecting seat 12 cannot reciprocate, when the electromagnet 171 is energized, the telescopic rod 172 is adsorbed upward, and the telescopic rod 172 and the limiting member 18 will not have a restrictive effect on each other, so that in manual mode, the telescopic element 10 and the connecting seat 12 can be controlled to move together as a transition section.

[0036] like Figure 3As shown, as a preferred embodiment of the above embodiment, a fixed clamping seat 19 is fixedly provided on the connecting seat 12, and a movable clamping seat 20 is slidably provided on the fixed clamping seat 19. The top of the movable clamping seat 20 is the same size as the fixed clamping seat 19, and a limiting platform 201 is fixedly provided at the bottom of the movable clamping seat 20. A second spring 202 for pushing the movable clamping seat 20 to move downward is provided between the limiting platform 201 and the fixed clamping seat 19. Under the push of the second spring 202, the movable clamping seat 20 can be driven downward and clamped with the fixed clamping seat 19. The interval between the movable clamping seat 20 and the fixed clamping seat 19 forms a space for the second pull wire 14 to pass through. The engaging cavity 21 engages with the end of the second pull wire 14, and the space of the engaging cavity 21 is larger than the end of the second pull wire 14, so the end of the second pull wire 14 can be restricted. When the clamping force between the movable clamping seat 20 and the fixed clamping seat 19 is greater, it can make the fixed clamping seat 19 and the movable clamping seat 20 more difficult to separate, thereby preventing the end of the second pull wire 14 from detaching from the engaging cavity 21. When replacement is needed, the movable clamping seat 20 can be pulled out upwards, and the second pull wire 14 can be taken out from the engaging cavity 21 and the gap between the movable clamping seat 20 and the fixed clamping seat 19, thereby improving the efficiency of replacement.

[0037] As a preferred embodiment of the above embodiment, the base 16 is further provided with 23 for detecting the movable displacement of the telescopic element 10, and the connecting seat 12 is further provided with 24 for detecting the displacement of the extended end of the telescopic element 10. The position of the telescopic element 10 and the length of the extended end of the telescopic element 10 can be detected by setting 23 and 24. Therefore, in manual mode, step-by-step adjustment can be achieved through the displacement detected by 23, and step-by-step adjustment can be achieved through the constant of the extended end of the telescopic element 10 detected by 24 during automatic detection. Therefore, for control operations such as gear positions, step-by-step adjustment control can be effectively performed.

[0038] like Figure 4 As shown, as another embodiment, in this embodiment, a cover plate 22 is fixedly provided on the top of the base 16, and the cover plate 22 also adopts a bent structure, which is used to protect various components installed inside the base 16 to avoid damage when working under some complex conditions.
