The utility model provides a blocking mechanism for preventing a four-way vehicle from falling, and aims to solve the problem that in the prior art, the four-way vehicle misjudges that a lifting machine reaches a shelf of the layer, and then the four-way vehicle rushes out of the shelf and falls to the ground to cause a safety accident.
For easy understanding, a specific flow in the embodiment of the present utility model is described below, referring to fig. 1 to 4, a blocking mechanism for preventing a four-way vehicle from falling down in the embodiment of the present utility model includes a lifter 1, a blocking portion 3, a pushing portion 4, and an elastic member 5; the elevator 1 comprises an elevator frame 10, wherein each layer of the elevator frame 10 is provided with a side beam 12 aligned with the four-way vehicle 2, and an elevator bucket 11 capable of lifting up and down is arranged in the elevator frame 10; the support frame 6 is mounted on the side cross beam 12, the blocking part 3 is rotatably arranged on the support frame 6, and the side cross beam 12 faces the four-way vehicle 2 moving out of the goods shelf 8.
The pushing part 4 is installed on the lifting bucket 11, the pushing part 4 can lift up and down along with the lifting bucket 11, the pushing part 4 is used for pushing the blocking part 3 to rotate at the side cross beam 12, so that when the blocking part 3 is pushed by the pushing part 4, the horizontal state is arranged in the supporting frame 6, the four-way vehicle 2 can pass between the goods shelf 8 and the lifting machine 1, when the pushing part 4 does not work, the blocking part 3 is in the vertical state in the supporting frame 6, and at the moment, the blocking part 3 prevents the four-way vehicle 2 from passing between the lifting bucket 11 and the goods shelf 8.
One end of the elastic component 5 is connected with the supporting frame 6, and the other end is connected with the blocking part 3, so that when the pushing part 4 retracts to the original position, the blocking part 3 is driven to return to the original position, namely, the blocking part 3 is in a vertical state in the supporting frame 6, and the four-way vehicle 2 is prevented from passing between the lifting machine 1 and the goods shelf 8.
In actual use, when the lifting bucket 11 in the lifting machine 1 is not fully lifted to the corresponding multi-layer goods shelf 8, the blocking part 3 is in a vertical state and used for preventing the four-way vehicle 2 from passing between the goods shelf 8 and the lifting machine 1, when the lifting bucket 11 in the lifting machine 1 reaches a set position, the pushing part 4 pushes the blocking part 3 at this time, the blocking part 3 is pushed to rotate anticlockwise by taking the shaft on the support frame 6 as a fulcrum, and the blocking part 3 is horizontally arranged in the support frame 6 after rotation, so that the four-way vehicle 2 can pass between the goods shelf 8 and the lifting machine 1.
Then, the four-way vehicle 2 enters the elevator 1, when the elevator 1 drives the four-way vehicle 2 to move up and down, the pushing part 4 retracts to the original position, the blocking part 3 is restored to the vertical state in the supporting frame 6 through the elastic part 5, so that the four-way vehicle 2 is prevented from passing between the elevator 1 and the goods shelf 8, and the safety of the four-way vehicle 2 in use is greatly improved by the operation flow, and the reliability is high.
The blocking part 3 may be a rotating baffle plate 31 rotatably arranged in the supporting frame 6 or may also include at least two rotating baffle plates 31 rotatably arranged in the supporting frame 6, and the two rotating baffle plates 31 are connected through a connecting rod 30, because the rotating baffle plate 31 can rotate around an axis on the supporting frame 6, when the pushing part 4 pushes the rotating baffle plate 31, the rotating baffle plate 31 can be made to rotate anticlockwise on the supporting frame 6, so that the rotating baffle plate 31 is in a horizontal position to give way to the four-way vehicle 2.
In this embodiment, the pushing portion 4 includes an electric push rod 40 disposed on the lifting bucket 11, where the electric push rod 40 drives the push plate 41 to move forward, and then the push plate 41 is utilized to push the rotating baffle 31, and the rotating baffle 31 rotates counterclockwise on the supporting frame 6, so as to give way to the four-way vehicle 2.
In this embodiment, the elastic member 5 is a tension spring, and of course, may be other members, and only needs to have a function of automatically restoring the initial state.
As a further illustration of the present utility model, the side beam 12 is further provided with a centering baffle 7, where the centering baffle 7 blocks the rotating baffle 31 after extending forward, and the centering baffle 7 in this embodiment is disposed on the right side of the rotating baffle 31, so that when the elastic member 5 drives the rotating baffle 31 to return to the original position, the rotating baffle 31 is effectively prevented from being excessively shifted to the right.
Referring to fig. 3 to 4, in a practical application scenario, the elevator comprises an elevator 1 and a goods shelf 8 which is in butt joint with the elevator 1, a four-way vehicle 2 is positioned on the goods shelf 8, a pushing part 4 is installed in a lifting bucket 11 of the elevator 1, and a blocking part 3 is installed on a side beam 12 of each layer of an elevator frame 10.
When the four-way vehicle 2 needs to move to another layer of the goods shelf 8, the lifting hopper 11 in the lifting machine 1 moves upwards, and the electric push rod 40 is always in a contracted state in the process that the lifting hopper 11 does not move to the corresponding layer of the goods shelf 8, at this time, the rotating baffle 31 is positioned at the vertical position of the supporting frame 6, and the four-way vehicle 2 cannot pass between the lifting machine 1 and the goods shelf 8.
When the lifting hopper 11 in the lifting machine 1 moves to a set position, the electric push rod 40 extends forwards when the lifting machine is in butt joint with a four-way car, the rotating baffle plate 31 is rotated anticlockwise, and accordingly the rotating baffle plate 31 is horizontally arranged in the supporting frame 6 and then gives way to the four-way car 2, and therefore the four-way car 2 can pass between the lifting machine 1 and the goods shelf 8.
When the four-way car 2 is positioned in the lifting hopper 11 of the elevator, the electric push rod 40 is in a contracted state again, the rotating baffle plate 31 is vertically arranged to block the four-way car 2, and finally the lifting hopper 11 drives the four-way car to reach any layer of the goods shelf 8, then the rotating baffle plate 31 is rotated anticlockwise under the driving of the electric push rod 40 to give way to the four-way car, the four-way car 2 enters the corresponding goods shelf 8 layer, in the whole operation process, the four-way car 2 can be prevented from being flushed out when the lifting hopper 11 does not reach the position through the cooperation of the electric push rod 40 and the rotating baffle plate 31, and the safety and the reliability of the four-way car 2 in operation are improved.
The above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
