The working principle of the embodiment is as follows:
two guide plates 2, a locking plate 1 and an elastic limiting device 6 are arranged corresponding to each floor.
When car 7 begins to arrive certain floor, locking lever 3 goes up hemispheroid 30 and deflector 2 contact, deflector 2 slowly extrudes locking lever 3, it removes to get locking lever 3 to keeping away from locking plate 1 direction, thereby make locking lever 3 go up hemispheroid 30 can jump locking plate 1, because elasticity stop device 6 is far away from the boss on locking lever 3, consequently this in-process boss can not be with 6 effects of elasticity stop device, locking lever 3 aligns with the lockhole when car 7 stops to target in place, locking lever 3 inserts in the lockhole, realize the locking, the condition emergence of taking place to prize or car 7 suddenly subsides when big goods have been avoided when getting into.
When the cage door 8 of the cage 7 is opened, the cage door drives the mounting part 53 to move towards the lock rod 3, so that the situation that the lock rod 3 is not inserted into the lock hole and then a heavy object is put into the cage 7 due to certain hysteresis of the first spring is avoided, the first extrusion surface of the extrusion part 54 extrudes the pulley 523 at the beginning in the process that the mounting part 53 is inserted into the slot on the lock rod 3, so that the lifting rod 524, the connecting rod 522, the moving seat 521 and the elastic hook assembly 51 are lowered, the third spring 525 is compressed, and then the second pressing surface presses the pulley 523, so that the elastic hook assembly 51 is ensured to be at a lower position, the tip of the hook lever 511 protrudes out of the mounting portion 53, when the hook lever 511 is brought into contact with the locking lever 3, since the tip of the hook lever 511, which protrudes out of the mounting portion 53, is slowly pressed into the mounting portion 53 by the locking lever 3, when the hook lever 511 is aligned with the hook hole, the hook lever 511 is inserted into the hook hole under the elastic force of the second spring 512, and the lock lever 3 is supported by the support ring 31 at this time.
The landing door is opened at the same time when the compartment door 8 is opened, and at the moment, heavy objects such as goods enter the elevator.
In the closing process of the compartment door 8, the compartment door 8 is closed, the installation part 53 drives the lock rod 3 to move through the hook rod 511, the distance that the installation part 53 drives the lock rod 3 to move is long, the convex part 32 on the lock rod 3 can act on the limit pin 62, the convex part 32 crosses the limit pin 62, the limit pin 62 blocks the lock rod 3 to be inserted into the lock hole, the lock rod 3 is matched with the lock plate 1 to prevent the subsequent lift of the compartment door 7 from moving, when the compartment door 8 is completely closed, the pulley 523 is contacted with the first extrusion surface, under the elasticity of the third spring 525, the movable seat 521 pulls the hook rod 511 to retract into the installation part 53, the hook rod 511 releases the lock rod 3, the lock rod 3 has the tendency of moving in the lock plate 1 under the elasticity of the first spring, because the convex part 32 is matched with the limit pin 62, the lock rod 3 cannot.
Finally, the car 7 is lifted, the car 7 is moved in the vertical direction with respect to the elastic limiting device 6, and the limiting pin 62 is disengaged from the convex portion 32, so that the lock lever 3 continues to move in a direction away from the mounting portion 53 under the first spring elastic force, so that the lock lever 3 can act with the next guide plate 2 and the lock plate 1.
If the car 7 does not stop corresponding to the floor, because the car 7 moves fast, when the lock rod 3 is aligned with the lock hole on the lock plate 1 corresponding to the floor, the lock rod 3 is not inserted into the lock hole and the car 7 has driven the lock rod 3 away because the first spring is extended with a certain hysteresis, and the blocking effect cannot occur.
The design idea of this embodiment is as follows: firstly, in order to realize that the car 7 can be locked when the car 7 reaches each floor, the lock rod 3, the first spring, the guide plate 2 and the lock plate 1 are designed, so that automatic locking is realized, and the need of other driving equipment is avoided; subsequently, in order to save a power source for separating the lock rod 3 from the lock hole, the mounting portion 53 and the elastic hook assembly 51 are designed, so that the elastic hook assembly 51 can hook the lock rod 3 when the compartment door 8 is opened, the lock rod 3 can be driven to move by the hook rod 511 when the compartment door 8 is closed, and the lock rod 3 is separated from the lock hole; then, in order to enable the lock rod 3 to be disengaged from the hook rod 511, the elastic moving component 52 is designed, so that the elastic moving component 52 can drive the elastic hook component 51 to be disengaged from the lock rod 3 under the elastic force of the third elastic component, and the lock rod 3 can subsequently realize a locking function; finally, in order to avoid that the lock rod 3 still can be inserted into the lock hole to influence the normal lifting of the car 7 after the lock rod 3 is released by the hook rod 511, the elastic limiting device 6 is designed, so that the lock rod 3 cannot be inserted into the lock hole immediately under the obstruction of the elastic limiting device 6 after the lock rod 3 is pulled out by the hook rod 511, and the lock rod 3 can be restored to the position capable of acting with the guide plate 2 after the car 7 is lifted.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
