To ensure that the aerial work device stops working, i.e. after the arm support 2000 returns to the original position, the locking mechanism 100 is opened to lock the rotary table 300.

Specifically, when the aerial work device stops working, the second position detecting element 2300 may detect that the telescopic arm 2200 returns to the retracted state, and the telescopic arm 2200 may stop on the support 2400, and the stroke switch 2500 is activated by pressing the telescopic arm 2200, so that the second position detecting element 2300, the stroke switch 2500 and the driving element 30 transmit signals, thereby controlling the driving element 30 to drive the lock tongue 20 to move from the unlocking position to the locking position.

Alternatively, the foregoing embodiments may be combined, that is, the second position detecting element 2300 may be a length angle sensor, that is, the second position detecting element 2300 may be configured to simultaneously detect a telescopic state of the telescopic arm 2200 and an angle between the telescopic arm 2200 and a horizontal plane, when the high-altitude operation apparatus stops working, under a cooperation effect of the second position detecting element 2300 and the travel switch 2500, it may be detected that the telescopic arm 2200 stops working and returns to a home position, that is, the telescopic arm 2200 returns to a retracted state, the angle between the telescopic arm 2200 and the horizontal plane is at a predetermined angle, and the telescopic arm 2200 stops resting on the support 2400, at this time, the second position detecting element 2300 and the travel switch 2500 may transmit signals to the driving element, so as to activate the locking mechanism 100 to lock the turntable 300.

According to some embodiments of the present invention, the aerial working device may include a controller, and the controller respectively transmits signals to the driving member 30, the first position detecting member 40, the second position detecting member 2300 and the stroke switch 2500, so as to control the locking and unlocking of the locking mechanism 100.

When the high-altitude operation device stops working, the turntable 300 stops rotating, the telescopic arm 2200 contracts and stops on the support 2400, at this time, the second position detecting element 2300 can detect that the telescopic arm 2200 is in a contracted state, and the travel switch 2500 on the support 2400 is started as the telescopic arm 2200 stops on the support 2400, so that the controller can receive a signal of returning the boom 2000, thereby controlling the locking mechanism 100 to lock the turntable 300, and after the locking mechanism 100 finishes locking, the first position detecting element 40 can detect the position of the bolt 20, thereby ensuring the locking of the turntable 300.

The utility model provides an automatic locking device of revolving platform 300 effectively solves the problem that needs artifical manually operation mechanical structure locking and unblock, can realize automatic locking and automatic unblock. And the cost is lower. An automatically retractable driving member 30 is provided on the turntable 300 to drive the locking shaft 22 for automatic locking and automatic unlocking.

According to the technical scheme of the utility model: the bracket 10 is welded on the rotary table 300, and the bracket 10 is formed by welding two side mounting plates (i.e. a first side plate 112 and a second side plate 113), a fixing plate 111 and a cylinder. The sliding slots (i.e., the limiting slots 114) are formed on the side mounting plates, and the hinge shafts 50 penetrate through the sliding slots (i.e., the limiting slots 114) of the side mounting plates (i.e., the first side plate 112 and the second side plate 113) and pass through the hinge holes of the connectors 21, so as to hinge the connectors 21 of the driving member 30 together. The locking shaft 22 is screwed into a hole below the connector 21 through an upper threaded portion to connect the two together. Locking shaft 22 passes through the barrel when connected, which may improve the stability of locking shaft 22. The driving member 30 is automatically extended and retracted, and is one of an electric cylinder and a hydraulic cylinder. The rotary support plate (i.e., support 200) is perforated and the locking shaft 22 is inserted.

When the turntable 300 is ready to rotate, the driving member 30 receives a rotation command, the detecting member detects whether the locking device (i.e., the locking mechanism 100) is unlocked, if not, the locking device (i.e., the locking mechanism 100) is automatically unlocked to perform cylinder contraction, the hinge shaft 50 connects the driving member 30 and the connecting head 21, and the hinge shaft 50 moves upward in the sliding grooves (i.e., the limiting grooves 114) of the side mounting plates (i.e., the first side plate 112 and the second side plate 113) to drive the connecting head 21 to move upward. The lower end of the connecting head 21 is connected with a locking shaft 22, and the locking shaft 22 is driven to move upwards in the cylinder until the locking shaft 22 leaves the rotary supporting plate (i.e. the supporting table 200). At this time, the cylinder of the driving unit 30 stops contracting, and the turntable 300 can rotate. Such as unlocking, directly executes the turntable 300 slewing command. When the rotary table 300 rotates, the rotary table 300 and the driving member 30 realize program locking, and the driving member 30 cannot work.

When the operation is stopped, the controller sends an operation stopping instruction, the length angle sensor (i.e., the second position detecting element 2300) can detect the telescopic position of the arm support 2000, so as to detect whether the arm support 2000 is completely contracted, and if the arm support 2000 is not contracted in place, the locking device (i.e., the locking mechanism 100) does not act. Meanwhile, the length angle sensor (i.e., the second position detecting element 2300) may also be configured to detect an included angle between the arm support 2000 and a horizontal plane, so as to ensure whether the arm support 2200 is at a predetermined angle, detect whether the arm support 2000 falls on the support 2400 through the travel switch 2500, and disable the locking device (i.e., the locking mechanism 100) if the arm support is not at the predetermined angle. When the length angle sensor (i.e., the second position detecting element 2300) detects that the boom 2000 returns to the position, that is, the length angle sensor (i.e., the second position detecting element 2300) detects that the boom 2000 returns to the predetermined included angle with the horizontal plane, and the boom 2000 is in the contracted state, and at the same time, the travel switch 2500 detects that the boom 2000 returns to the zero position, the locking device starts to perform the automatic locking operation, the driving element 30 receives a signal, and the cylinder extends out to drive the hinge shaft 50 to move downward in the sliding grooves (i.e., the limiting grooves 114) of the side mounting plates (i.e., the first side plate 112 and the second side plate 113) and drive the connector 21 to move downward. The connector 21 is connected to a locking shaft 22, and drives the locking shaft 22 to move downward in the cylinder until the locking shaft 22 is inserted into a predetermined distance from a hole on the rotary support plate (i.e., the support table 200). At this time, the body of the driving member 30 stops extending, so that the automatic locking of the turntable 300 is realized, and after the automatic locking, the program locking of the turntable 300 and the driving member 30 is realized, so that the turntable 300 cannot work. By arranging the automatic locking device of the rotary table 300, the rotary table 300 can be automatically unlocked during working and can be automatically locked after working is finished, and the rotary table 300 cannot be operated and rotated after the program control driving piece 30 is locked. Convenience and safety in the working machine are improved.

The utility model discloses an automatic locking device (locking mechanism 100 promptly) of revolving platform 300 can effectively solve the problem that needs artifical manually operation mechanical structure locking and unblock, can realize automatic locking and automatic unblock according to the procedure. In addition, the safety can be improved. And the overall manufacturing cost of the present application is lower than that of the gear mesh locking mechanism 100.
