The elongated slot that lock pin rotates horizontally；The nearer one end of the long slot distance safety supporting legs is A ends, and long slot distance safety supporting legs are farther out
One end is B ends.
The joining beam other end described in the utility model is provided with the kidney slot for locking.
The kidney slot of joining beam described in the utility model, when in the square hole of joining beam insertion closing piece, the kidney slot and lock of joining beam
Block transverse direction mounting hole is corresponding.
In insertion telescopic arm elongated slot in rotation lock pin one end described in the utility model, the other end and closing piece transverse direction mounting hole pair
Should.
The beneficial effects of the utility model are：The safe self-locking function of dolly can be achieved, do not extended out in safety supporting legs
In the case of position, security lock arrangement is locked automatically, and dolly switching mechanism can not be overturn, and only safety supporting legs stretch out just enter in place
Row upset, has been effectively ensured the safe to use of dolly.The utility model can realize the linkage of safety supporting legs and self-locking device, stretch out
In place-unblock, does not extend out in place-self-locking；Coordinated using rotation lock pin and closing piece, simple in construction, function is reliable；Linkage self-locking
Mechanism principle is simple, practical, can be widely used in the various technical fields for needing linkage self-locking.
Brief description of the drawings
Fig. 1 is to apply loading transfer car(buggy) schematic diagram of the present utility model.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is unlocking condition schematic diagram of the present utility model.
In figure, safety supporting legs device 1；Chassis assembly 2；Longitudinal beam of underframe 3；Rollover stand 4；Security lock arrangement 5；Hydraulic system 6；
Push away handrail 7；Joining beam 8；Closing piece 9；Bearing pin 10；Telescopic arm 11；Rotate lock pin 12.
Embodiment
As shown in figure 1, chassis assembly is loads the bogey of transfer car(buggy), bottom is provided with for mobile movable pulley, preceding
End is provided with the bearing for rollover stand upset, rear end be provided with it is artificial promote that vehicle advances push away handrail 7 and drive rollover stand upset
Hydraulic system 6.Rollover stand 4 is the support meanss of load, passes through the bearing in chassis assembly 2 under the driving of hydraulic system 6
Realize flip-flop movement.The lifting rollover states that transfer car(buggy) is mounted with delivery article are loaded, under this state, safety supporting legs device 1 is stretched
Go out and consolidate support ground, after supporting leg drives telescopic arm 11 to stretch out in place, the driving rotation lock pin 12 of telescopic arm 11 is from the hole of joining beam 8
Rotational disengagement is to unlocking condition.Safety supporting legs equipment safety support leg device 1 stretches out and firm support ground, at security lock arrangement 9
Under unlocking condition, hydraulic system can drive the rollover stand equipped with goods to carry out upset lifting.
As shown in Fig. 2 telescopic arm 11 is threadedly coupled with safety supporting legs.Safety supporting legs are used to load transfer car(buggy) in rollover states
Safety supports, provide safety supports for the vehicle turnover in the case of loading；The telescopic boom of safety supporting legs does not extend out in place, lock
Locking apparatus can not be opened, and rollover stand can not be overturn, and ensure safety.The longitudinal direction of closing piece 9 is provided with square hole, on rollover stand
The upset insertion of joining beam 8 is with separating；Mounting hole is transversely provided with, for rotating being rotatably inserted into and screwing out for lock pin 12.The side of closing piece 9 is set
There is the rotary shaft being rotatably assorted with rotation lock pin 12.Bearing pin 10 for rotating the rotation of lock pin 12 is threadably coupled within closing piece 9, makees
To rotate the rotary shaft of lock pin 12.Rotation lock pin 12 is actively connected on closing piece 9 by bearing pin 10, by rotating two limit positions
Two functions of locking and unblock can be achieved.The upper end of joining beam 8 is fixedly connected on the turnover rollover stand of transfer car(buggy) is loaded, another
