Description

Technical Field

[0001] The invention relates to a remote control device for an unmanned tower crane, in particular to a remote driving chair for an unmanned tower crane. Background Art

[0002] Unmanned tower crane remote control technology enables remote control of tower cranes through a digital cockpit. Relying on 5G networks and AI visual recognition technology, it can respond to and coordinate data such as the tower crane's operating trajectory and lifting load. It can achieve all-round real-time monitoring of the tower crane's operating status and efficient construction.

[0003] Since the remote crane operator is located on the ground, he relies on the images transmitted to the display screen by the camera on the crane to observe the on-site situation, and lacks actual physical sensation. For some inexperienced operators, this kind of tower crane operation without senses may increase the risk of misoperation due to a certain psychological burden.

[0004] In addition, the tower crane platform will perform a self-check during the initial startup stage. During this self-check stage, the image may have been transmitted to the cockpit display screen, but the control system is not actually fully ready. At this time, the operator may mistakenly believe that the control system is ready after observing the image and directly operate the console, which poses a major safety hazard. Summary of the Invention

[0005] The present invention aims to solve the problems existing in the remote control of unmanned tower cranes in the prior art and provides a remote driving chair for an unmanned tower crane.

[0006] In order to solve the above technical problems, the present invention is solved by the following technical solutions: A remote driving chair for an unmanned tower crane comprises a driving chair main body, wherein an operating console is provided on the driving chair main body; the operating console has an operating console main body, wherein the operating console main body has an operating panel; a cover is hingedly provided on the operating console main body corresponding to the operating panel, and the cover has an open posture and a closed posture; a locking mechanism for keeping the cover in a closed posture is provided on the operating console main body, and a cascade unlocking mechanism for unlocking the locking mechanism is provided on the driving chair main body; the cascade unlocking mechanism is used to enable the locking mechanism to release the cover from being kept in a closed posture, so that the cover can switch from a closed posture to an open posture; wherein, the cover blocks the operating panel when it is in a closed posture, and releases the blockage of the operating panel when it is in an open posture.

[0007] Preferably, the locking mechanism includes an electromagnetic lock provided on the console body and a corresponding lock catch provided on the cover, and the cascade unlocking mechanism is used to generate an unlocking command to the electromagnetic lock. The electromagnetic lock and the lock catch cooperate to lock the cover, and the cover can be opened only when the corresponding unlocking command is generated.

[0008] Preferably, the cascade unlocking mechanism includes an unlocking branch connected to the main power supply branch of the operating console, and the unlocking branch includes a first unlocking switch and a second unlocking switch connected in series; the unlocking branch is used to connect to the main power supply branch of the operating console when the first unlocking switch and the second unlocking switch are both in a closed state to generate an unlocking instruction.

[0009] As a preference, the main power supply branch of the operating console is connected to the power supply through the power supply switch, so that the power supply switch and the two unlocking switches are mutually restricted, effectively avoiding the risk of misoperation.

[0010] Preferably, the power switch is provided on the console body, and a shielding mechanism is provided on the console body at a position corresponding to the power switch. The shielding mechanism has a first position and a second position. When the shielding mechanism is in the first position, the power switch is shielded; when the shielding mechanism is in the second position, the shielding of the power switch is released. The provision of the shielding mechanism can shield the power switch, thereby preventing accidental activation of the power switch during normal operation.

[0011] Preferably, the shielding mechanism includes a shielding motor, and the operating table is provided with a first detection switch for being triggered when the cover is in an open position and a second detection switch for being triggered when the cover is in a closed position; when the first detection switch is triggered, a first action instruction for controlling the shielding motor to perform a first action is generated; when the second detection switch is triggered, a second action instruction for controlling the shielding motor to perform a second action is generated; when the shielding motor performs the first action, the shielding mechanism is kept in the first position; when the shielding motor performs the second action, the shielding mechanism is kept in the second position. The shielding mechanism matches the opening and closing of the cover, so that during the initial startup stage, the cover can only be opened when the power switch is in the on state, and at the end of the construction stage, the power switch is turned off only when the cover is completely covered on the operating panel, preventing personnel from still using the operating table after turning off the power switch, so as to ensure that the operating table is effectively protected after the operator leaves.

[0012] Preferably, the driving chair body includes a base and a driving chair, the first unlocking switch includes a left pedal assembly provided at the base and a left-pedal microswitch provided at the left pedal assembly, the second unlocking switch includes a right pedal assembly provided at the base and a right-pedal microswitch provided at the right pedal assembly, the left pedal assembly and the right pedal assembly have the same structure and both include a foot pedal mounting base and a foot pedal, and when the two foot pedals are stepped on, the left-pedal microswitch and the right-pedal microswitch are respectively in a closed state. The two unlocking switches are connected in parallel to further reduce the risk of accidental touch, and at the same time, by means of foot pedal triggering, the operator only needs to step on the foot pedals with both feet to achieve the simultaneous closure of the two unlocking switches, which is very convenient to operate.

[0013] Preferably, the base is provided with a pedal locking mechanism, comprising a pedal baffle mounted on the pedal mounting base and capable of being positioned below the pedal. The pedal baffle can be moved horizontally out from under the pedal on the pedal mounting base. The pedal mounting base is provided with a pedal baffle slide for horizontal movement of the pedal baffle and a locking spring for driving the pedal baffle toward the bottom of the pedal. The pedal locking mechanism can block the pedal, preventing accidental stepping on the pedal and triggering the electromagnetic lock of the cover to unlock.

[0014] Preferably, a pedal unlocking mechanism is provided between the base and the driver's seat. The pedal unlocking mechanism comprises a drive plate disposed below the seat that moves downward when the seat is depressed. A connecting rope is connected between the drive plate and the footrest, which is used to move the footrest horizontally out from under the footrest during the downward movement of the drive plate. The pedal unlocking mechanism allows the operator to unlock the footrest directly after sitting in the seat, eliminating unnecessary movement and providing extremely convenient operation.

[0015] Preferably, the driver's chair includes a support base and a seat mounted on the support base, the seat including a backrest and a seat, a connecting plate disposed within the seat, and a plurality of connecting rods disposed on the connecting plate for connecting to a drive plate disposed below the support base. The connecting rods extend through the support base, and the connecting rods are provided with drive plate return springs, the upper and lower ends of which respectively abut against the connecting plate and the support base. The drive plate return springs are configured to return the drive plate to its original position after a person leaves the driver's chair, thereby causing the footrest block to reposition below the footrest.

[0016] The present invention has significant technical effects due to the adoption of the above technical solutions: The present invention can prevent operators from directly operating the operation panel after the operation console is powered on, but requires operators to make sufficient preparations before operating the operation panel, thereby effectively reducing safety hazards in the initial startup stage.

[0027] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0028] Example 1 A remote driving chair for an unmanned tower crane, such as Figures 1-10 As shown, it includes a driving chair body 1, the driving chair 102 includes a support base 119 and a seat arranged on the support base 119, the seat includes a seat back 120 and a seat 121, and an operating table is provided at the driving chair body 1; the operating table has an operating table body 2, and the operating table body 2 has an operating panel 3, the operating panel 3 is provided with an operating handle and an operating button, and the upper end of the base 101 is provided with a slide rail, and the support plate is slidably connected to the slide rail, so that the front and rear position of the driver can be adjusted to enable the operator to better observe the display screen.

[0029] A cover plate 4 is hingedly provided on the operating table body 2 corresponding to the operating panel 3, and the cover plate 4 has an open posture and a closed posture; wherein, a first connecting piece is provided on the rear side surface of the operating table, and a second connecting piece is provided on the rear side of the cover plate 4, which is hinged to the first connecting piece through a hinge axis. During operation, the cover plate 4 can be flipped around the hinge axis toward or away from the operating panel 3.

[0030] A locking mechanism for keeping the cover 4 in a closed position is provided at the operating table body 2, and a cascade unlocking mechanism for unlocking the locking mechanism is provided at the driver's chair body 1; the cascade unlocking mechanism is used to enable the locking mechanism to release the cover 4 from being in a closed position, so that the cover 4 can switch from a closed position to an open position, and the position switching of the cover 4 can be manually flipped; wherein, when the cover 4 is in a closed position, it blocks the operating panel 3, at which time the cover 4 is in a horizontal state and covers the operating panel 3, and when the cover 4 is in an open position, the obstruction to the operating panel 3 is released, and at this time the cover 4 can be flipped to a vertical state.

[0031] In this embodiment, the locking mechanism includes an electromagnetic lock 5 provided on the operating table body 2 and a lock buckle 6 correspondingly provided on the cover plate 4. The cascade unlocking mechanism is used to generate an unlocking instruction sent to the electromagnetic lock 5 and is connected to the power supply switch through the electromagnetic lock power supply branch.

[0032] By setting a locking mechanism between the cover 4 and the operation panel 3, the operation panel 3 is in a locked state when the driving chair 102 is in the initial state. At this time, the operator cannot directly operate the operation panel 3, preventing the operator from operating the operating console when the operator himself and the tower crane control system are not fully ready, effectively improving the operational safety in the initial startup stage.

[0033] The cascade unlocking mechanism in this embodiment includes an unlocking branch connected to the main power supply branch of the operating console, and the unlocking branch includes a first unlocking switch and a second unlocking switch connected in series; the unlocking branch is used to connect to the main power supply branch of the operating console when the first unlocking switch and the second unlocking switch are both in a closed state to generate an unlocking instruction.

[0034] Unlocking of the operating panel 3 is achieved through a cascade unlocking mechanism, that is, both unlocking switches need to be in a closed state before an unlocking instruction is generated, which can effectively avoid the risk of unlocking misoperation.

[0035] In this embodiment, the main power supply branch of the operating table is connected to the power supply through the power supply switch 7, that is, the main power supply branch of the operating table can be energized only when the power switch 7 is pressed, and the unlocking instruction will be issued only when the first unlocking switch and the second unlocking switch are closed when the main power supply branch of the operating table is energized, so that the power supply switch 7 and the two unlocking switches can be mutually restricted. The operator can only power the operating table by simply starting the power switch 7, and the cover 4 cannot be opened at this time. The cover 4 cannot be opened by simply closing the two unlocking switches without starting the power switch 7. Only when the power switch 7 is turned on first to power on the operating table, and then the two unlocking switches are closed, can the electromagnetic lock 5 be unlocked. If any switch is in the disconnected state, the electromagnetic lock 5 is in a locked state and cannot be opened.

[0036] In this embodiment, the power switch 7 is arranged on the operating table main body 2, and a shielding mechanism is provided at the operating table main body 2 corresponding to the power switch 7. The shielding mechanism has a first posture and a second posture; when the shielding mechanism is in the first posture, it blocks the power switch 7; when the shielding mechanism is in the second posture, the shielding formed on the power switch 7 is released.

[0037] The shielding mechanism includes a shielding motor 10, and a first detection switch 8 for being triggered when the cover 4 is in an open position and a second detection switch 9 for being triggered when the cover 4 is in a closed position are provided at the operating table; when the first detection switch 8 is triggered, a first action instruction for controlling the shielding motor 10 to perform a first action is generated; when the second detection switch 9 is triggered, a second action instruction for controlling the shielding motor 10 to perform a second action is generated; when the shielding motor 10 performs the first action, the shielding mechanism is kept in the first position; when the shielding motor 10 performs the second action, the shielding mechanism is kept in the second position, the first detection switch 8 and the second detection switch 9 are electrically connected to the shielding motor through a controller, and a corresponding pressing part that can press the first detection switch 8 and the second detection switch 9 is provided on the cover, and the first detection switch 8 and the second detection switch 9 are triggered by pressing.

[0038] The shielding mechanism also includes a switch shielding plate 126, one end of which is connected to the motor shaft of the shielding motor 10, and the other end constitutes a shield for the power switch 7. When the shielding motor 10 performs the first action, the switch shielding plate 126 can be rotated 180° counterclockwise to a position where it shields the power switch 7. When the shielding motor 10 performs the second action, the switch shielding plate 126 rotates 180° clockwise to a position away from the power switch 7. The setting of the shielding mechanism can achieve shielding of the power switch 7, which can It is possible to achieve that in the initial startup state, the power switch 7 is first pressed to power the operating table and then the locking mechanism of the cover 4 is triggered to unlock. During normal operation, the power switch 7 is blocked to prevent accidental touching of the power switch 7 during operation. At the same time, the power switch 7 is turned off only after the cover 4 is completely covered on the operation panel 3, forcing personnel to close the cover 4 first to make the operating table unusable before turning off the power switch 7, preventing personnel from still using the operating table after turning off the power switch 7, so as to ensure that the operating table is effectively protected after the operator leaves.

[0039] In this embodiment, the driving chair body 1 includes a base 101 and a driving chair 102. The first unlocking switch includes a left pedal assembly 11 provided at the base 101 and a left-pedal microswitch 111 provided at the left pedal assembly 11. The second unlocking switch includes a right pedal assembly 12 provided at the base 101 and a right-pedal microswitch 125 provided at the right pedal assembly 12. The left pedal assembly 11 and the right pedal assembly 12 have the same structure and both include a footrest mounting base 112 and a footrest 113. When the two footrests 113 are stepped on, they can respectively press the left-pedal microswitch 111 and the right-pedal microswitch 125 to close them. By providing two pedal assemblies on the base 101, the unlocking switch can be closed by stepping on the footrest 113 with both feet, thereby triggering the microswitch on the footrest mounting base 112, which is relatively convenient to operate.

[0040] In order to prevent other non-operating personnel from accidentally stepping on the foot pedal 113, a pedal locking mechanism is also provided at the base 101. The pedal locking mechanism includes a foot pedal baffle 114 mounted on the foot pedal mounting seat 112 and capable of being located under the foot pedal 113. The foot pedal baffle 114 can be horizontally moved out from under the foot pedal 113 on the foot pedal mounting seat 112. The foot pedal mounting seat 112 is provided with a foot pedal baffle slide groove 115 for horizontal movement of the foot pedal baffle 114 and a locking spring 116 for driving the foot pedal baffle 114 to move toward the bottom of the foot pedal 113.

[0041] A pedal unlocking mechanism is provided between the base 101 and the driving chair 102. The pedal unlocking mechanism includes a driving plate 117 arranged under the seat 121 and capable of moving downward when the seat 121 is pressed down. A connecting rope 118 is connected between the driving plate 117 and the footrest baffle 114 for driving the footrest baffle 114 to move horizontally out from under the foot pedal 113 during the downward movement of the driving plate 117.

[0042] Through the pedal locking mechanism and the pedal unlocking mechanism, the pedal can be stepped on only when the staff is sitting on the seat. For the staff, the pedal unlocking process will not produce unnecessary actions and will not increase the complexity of operation; for non-staff, such as cockpit cleaners or other personnel, there will be no unnecessary safety hazards caused by accidentally or intentionally stepping on the pedal, which will trigger the unlocking of the cover 4.

[0043] A connecting plate 122 is provided in the seat 121, and a plurality of connecting rods 123 for connecting to the drive plate 117 are provided on the connecting plate 122. The drive plate 117 is arranged under the support base plate 119. The connecting rod 123 passes through the support base plate 119 and the connecting rod is provided with a drive plate return spring 124 whose upper and lower ends respectively rest on the connecting plate 122 and the support base plate 119. After the operator leaves the seat, the drive plate 117 will return to its original state, and under the action of the locking spring 116, the footrest baffle 114 will move again to the bottom of the foot pedal 113 to block the foot pedal 113.

[0044] The entire driving process of the driving chair 102 in this embodiment is as follows: Step S1, the initial preparation stage, includes the following steps: Step S11: The operator first sits on the driving chair 102, and the footrest baffle 114 is moved away from under the footrest 113; Step S12: The operator first presses the power switch 7 to power the entire operating table, and then steps on the foot pedals 113 with both feet, triggering the left pedal micro switch 111 and the right pedal micro switch 125 on the left and right foot pedals 113 respectively; Step S13: At this time, the electromagnetic lock 5 in the locking mechanism of the cover plate 4 is opened, and the operator manually opens the cover plate 4 so that the cover plate 4 moves back to the operation panel 3, thereby opening the operation panel 3; Step S14: When the cover 4 is opened to a position perpendicular to the operation panel 3, the first detection switch 8 is triggered, causing the shielding motor 10 to drive the switch shielding plate 126 to shield the power switch 7; During the entire initial stage, the operator's various actions are coordinated with the corresponding trigger mechanism, and the actions can be completed in one go. There are no unnecessary and complicated operations, but they can be completed naturally. The sequence of each action also matches the natural sequence of the work process of regular personnel, which will not increase the inconvenience to the operator's operation. At the same time, it can enable the operator to make sufficient mental preparations at this stage, and provide sufficient time for the tower crane control system's power-on self-test process, thereby effectively reducing safety risks.

[0045] Step S2, tower crane operation stage: remotely control the tower crane through the operating handle and operating buttons on the operating panel 3; Step S3, the driving end stage, includes the following steps: Step S31: The operator first covers the cover 4 on the operation panel 3; Step S32: trigger the second detection switch 9, so that the shielding motor 10 drives the switch shielding plate 126 to move away from the power switch 7; Step S33: Press the power switch 7 to cut off the power supply of the entire operating table.

[0046] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application based on one or several embodiments provided in the present application to obtain other embodiments, and these embodiments do not exceed the scope of protection of the present application.

[0047] In short, the above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
