When the lifting platform 300 is close to the corresponding track, the pressing plate on the corresponding track presses the stopper 810, and when the lifting platform 300 reaches a predetermined position, the pressing plate on the corresponding track presses the stopper 810 into the lifting platform 300, and at this time, the third spring 820 is in a compressed state, so that the rail car is released. When the lifting platform 300 descends, the lifting platform 300 and the corresponding track are separated from each other, and the stopper 810 returns to the predetermined position under the elastic action of the third spring 820 under the condition of no upper pressure, so that the blocking state is formed again.
In other embodiments of the present invention, a locking mechanism is further provided, wherein the locking mechanism adopts a four-bar dead point structure, and when the railcar enters the lifting platform 300, the locking mechanism rotates to a dead point position so as to lock wheels of the railcar, thereby preventing the railcar from moving; in other embodiments, the device is further provided with a bolt mechanism, the bolt mechanism utilizes the structural principle that the power of an air cylinder pushes a bolt to extend out of a locking and retracting unlocking butt joint position and is guided by a guide key, and a sensing piece detects whether the bolt is in place for extending out of the locking and retracting unlocking.
Based on the above embodiments, the process of the present invention in practical use is as follows:
firstly, after the rail car enters the lifting platform 300, the wheels of the rail car are locked by the locking mechanism, and meanwhile, the stop block 810 in the secondary blocking device 800 limits the wheels, so that the rail car is fixed, and the rail car is prevented from being separated from the lifting platform 300.
Under the effect of dragging of lifting pulley block 520, lift platform 300 upwards moves between first support body 100 and second support body 200, guarantees that the process of rising of lift platform 300 is stable under the effect of counterweight pulley block 530, and at the in-process that lift platform 300 rises, if the condition of promoting the fracture of cable wire 522 takes place, swing inverted hanging tooth subassembly 400 and counterweight pulley block 530 can prevent lift platform 300 to fall jointly, improves the safety protection of railcar hoist mechanism to the visitor.
After the lifting platform 300 is lifted to the predetermined position, the locking mechanism releases the wheels, and at the same time, the secondary blocking device 800 is pressed at the predetermined position, thereby unlocking the movement state of the rail car.
In summary, the present invention provides a rail car lifting mechanism, which includes: a frame body; the lifting platform is arranged on the frame body in a sliding mode and used for lifting the rail car; the movable joint inverted hanging tooth assembly is arranged on the frame body and is connected with the lifting platform; the steel cable driving assembly comprises a plurality of wheel sets and a steel cable, the wheel sets are fixedly arranged on the lifting platform and the frame body, and the steel cable is wound on the wheel sets. The movable joint inverted hanging tooth assembly is arranged at the position where the lifting platform is connected with the frame body so as to reduce the impact force between the lifting platform and the frame body in the movement process, and the steel cable driving assembly is further arranged on the lifting platform and the frame body so as to drive the lifting platform to move.
It is to be understood that the invention is not limited to the examples described above, but that modifications and variations may be effected thereto by those of ordinary skill in the art in light of the foregoing description, and that all such modifications and variations are intended to be within the scope of the invention as defined by the appended claims.
