The invention can realize the linkage of the safety support leg and the self-locking device, and the safety support leg extends to the proper position for unlocking and does not extend to the proper position for self-locking; the rotary lock pin is matched with the lock block, so that the structure is simple, and the function is reliable; the principle of the linkage self-locking mechanism is simple and practical, and the linkage self-locking mechanism can be widely applied to various technical fields needing linkage self-locking.
Drawings
Fig. 1 is a schematic view of a loading wagon to which the present invention is applied.
Fig. 2 is a schematic structural view of the present invention.
Fig. 3 is a schematic view of the unlocking state of the present invention.
In the figure, a safety leg device 1; a chassis assembly 2; chassis stringers 3; a roll-over stand 4; a safety lock device 5; a hydraulic system 6; pushing the armrest 7; a link 8; a locking piece 9; a pin 10; a telescopic arm 11; the locking pin 12 is rotated.
Detailed Description
As shown in fig. 1, the chassis assembly is a loading device of the loading transfer vehicle, the lower part is provided with a moving wheel for moving, the front end is provided with a support for overturning the overturning frame, and the rear end is provided with a pushing handrail 7 for manually pushing the vehicle to advance and a hydraulic system 6 for driving the overturning frame to overturn. The roll-over stand 4 is a supporting device for carrying objects, and the roll-over movement is realized through a support on the underframe assembly 2 under the drive of the hydraulic system 6. The loading transfer trolley is loaded with a lifting and overturning state of the carried article, in this state, the safety support leg device 1 stretches out and stably supports the ground, and after the support legs drive the telescopic arms 11 to stretch out and reach the position, the telescopic arms 11 drive the rotary lock pins 12 to rotate from the holes of the link rod 8 to be disengaged to an unlocking state. Safety landing leg device the safety landing leg device 1 stretches out and firmly supports ground, and the safety lock device 9 is in the unlocking state, and the hydraulic system can drive the roll-over stand filled with goods to roll over and lift.
As shown in fig. 2, the telescopic arm 11 is screwed with the safety leg. The safety support legs are used for loading the safety support of the transfer trolley in a turnover state and providing the safety support for the turnover of the vehicle under the condition of carrying the object; the telescopic support arm of the safety support leg does not extend out to the right, the locking device cannot be opened, the roll-over stand cannot be turned over, and safety is guaranteed. The locking block 9 is longitudinally provided with a square hole for overturning, inserting and separating a link rod 8 arranged on the overturning frame; a kidney-shaped hole is provided transversely for the rotary insertion and unscrewing of the rotary lock pin 12. The side of the locking piece 9 is provided with a rotating shaft which is in running fit with the rotating lock pin 12. A pin 10 for rotating the rotary lock pin 12 is screwed to the lock block 9 as a rotation shaft of the rotary lock pin 12. The rotary lock pin 12 is movably connected to the lock block 9 through a pin shaft 10, and can realize two functions of locking and unlocking by rotating two limit positions. The upper end of the link rod 8 is fixedly connected to a turnover frame capable of being turned over by the loading transfer trolley, and the other end of the link rod can be inserted into and separated from a square hole of the locking block 9 through the turnover of the turnover frame. The link rod 8 is provided with a kidney-shaped groove for locking. The locking piece 9 is fixedly arranged on the side face of the chassis longitudinal beam of the loading transfer trolley, the telescopic arm 11 is movably connected in the chassis longitudinal beam of the loading transfer trolley, the side face of the telescopic arm 11 is provided with a long groove, and when the telescopic arm 11 slides in the chassis longitudinal beam, the long groove on the telescopic arm 11 drives the rotary lock pin 12 to rotate positively and negatively, so that the connection and disconnection of the link rod and the locking piece are realized, and the locking and unlocking of the safety lock device 9 are realized. The telescopic arm 11 is provided with a long groove for driving the rotary lock pin 12 to horizontally rotate. The end of the long groove, which is closer to the safety support leg, is a long groove A end, and the end of the long groove, which is farther from the safety support leg, is a long groove B end. After the telescopic arm 11 is retracted, the long groove A end on the telescopic arm 11 pushes the rotary lock pin 12 to rotate, and the rotary lock pin 12 is driven to rotate and insert into the locking block 9, so that the link rod 8 and the underframe assembly are locked into a whole. After the telescopic arm 11 stretches out and reaches a proper position, the long groove B end on the telescopic arm 11 drives the rotary lock pin 12 to reversely rotate, the rotary lock pin 12 is driven to rotate out of the locking block 9, and the connecting rod 8 is separated from the chassis.
As shown in fig. 3, the telescopic arm 11 extends out to a proper position, the long groove B end on the telescopic arm 11 drives the rotary lock pin 12 to rotate, the rotary lock pin 12 is driven to rotate out of the locking block 9, the link rod 8 is separated from the underframe, and unlocking of the interlocking device is achieved.
