In addition, the technical features of the different embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.
As shown in fig. 1 to 6, the anti-falling stacker crane 100 of the present utility model includes a main frame 1, a driving assembly 2 disposed on the main frame 1 for driving an object to lift, and an anti-falling structure.
The anti-falling structure comprises an anti-falling frame 3 fixed with the main frame 1 and an anti-falling assembly 4 arranged adjacent to the anti-falling frame 3.
The anti-falling rack 3 is provided with at least one anti-falling hole 31, the number of the anti-falling holes 31 is multiple, and the anti-falling holes 31 are arranged at intervals along the vertical direction.
As shown in fig. 2, 4, 5 and 6, the fall protection assembly 4 includes a support frame 41, a pull rod 42 connected with the driving assembly 2, a plug board 43 inserted into the fall protection hole 31, a stop plate 44 disposed below the plug board 43, a connection block 45, a first rotation pin 46, a second rotation pin 47, and a spring 48.
The pull rod 42 and the support frame 41 drive the anti-falling component 4 to move up and down.
The driving assembly 2 is configured to drive the pull rod 42 and the support frame 41 to move up and down, and the driving assembly 2 includes a sliding rail 21 fixed to the main frame 1, a sliding block 22 fixed to the sliding rail 21, a driving frame 23 fixedly connected to the sliding block 22 and the support frame 41, a chain 24 connected to the pull rod 42, and a driving member configured to drive the chain 24 and the pull rod 42 to move up and down.
The driving member is started to drive the chain 24 and the pull rod 42 to move up and down, so as to drive the support 41, the driving frame 23 and the slider 22 to slide along the sliding rail 21.
The support frame 41 includes a first support frame 411 extending in a vertical direction, and a second support frame 412 extending in a horizontal direction. The first supporting frame 411 is fixedly connected with the second supporting frame 412.
The pull rod 42 passes through the support 41 in the vertical direction and abuts against the support 41 at the lower end. Further, the pull rod 42 abuts against the second supporting frame 412, and further, the pull rod 42 indirectly abuts against the second supporting frame 412 through the connecting block 45.
The lower end of the pull rod 42 is provided with a supporting piece 421, and the upper end is provided with a limiting block 422.
The supporting member 421 is used for indirectly supporting the second supporting frame 412, the supporting member 421 is located below the connecting block 45, and when the pull rod 42 moves upward, the supporting member 421 drives the connecting block 45 and the second supporting frame 412 to move upward.
The limiting block 422 is used for preventing the pull rod 42 from moving downwards under the action of gravity to be separated from the second supporting frame 412.
The connecting block 45 is disposed between the second supporting frame 412 and the supporting member 421, the connecting block 45 is disposed in a hollow manner, and the spring 48 is disposed in the connecting block 45 and sleeved on the pull rod 42.
When the pull rod 42 suddenly falls off from the connection and slides down, the connecting block 45 can be driven to move down by the elastic force of the cooperative spring 48.
The insertion plate 43 has a first state in which the insertion plate 43 is not inserted into the fall preventing hole 31, and a second state in which the insertion plate 43 is inserted into the fall preventing hole 31 and abuts against the stopper plate 44.
The springs 48 are in a compressed state when the insert plate 43 is in the first state, and the springs 48 are restored to provide the downward movement of the connection block 45 when the insert plate 43 is changed from the first state to the second state.
One end of the insertion plate 43 is close to the anti-falling frame 3, and the other end of the insertion plate 43 is connected with the pull rod 42, in this embodiment, the other end of the insertion plate 43 is indirectly connected with the pull rod 42 through the connection block 45.
The insert plate 43 is connected to the connection block 45 by a second pivot pin 47. I.e. when the connection block 45 moves downward, one end of the insertion plate 43 is driven to move downward. In this embodiment, the insert plate 43 is provided with a connection hole 431 for the second rotation pin 47 to pass through, and the connection hole 431 extends along the length direction of the insert plate 43, so that the second rotation pin 47 can move in the connection hole 431 along the horizontal direction to be unseated.
The insertion plate 43 is in insertion fit with the support frame 41 through a first rotation pin 46, and further, the insertion plate 43 is connected with the first support frame 411 through the first rotation pin 46.
When the pull rod 42 falls under the action of gravity, the insert plate 43 is driven to rotate along the first rotating pin 46, so that the insert plate 43 is inserted into the anti-falling hole 31 to enter the second state. The stopper plate 44 is provided on a side of the insertion plate 43 away from the fall prevention rack 3 to abut against the insertion plate 43 when the insertion plate 43 is inserted into the fall prevention hole 31.
When the plugboard 43 is in the first state, the end close to the falling prevention frame 3 is lower than the end connected with the pull rod 42.
The insert plate 43 is disposed at an end close to the fall preventing rack 3 so as to be inclined such that the length above the insert plate 43 is smaller than the length below. Preferably, when the insert plate 43 is in the first state, a surface of the insert plate 43 facing the anti-falling rack 3 is parallel to the anti-falling rack 3, and of course, the insert plate 43 may be not parallel, so long as the insert plate 43 does not collide with the anti-falling rack 3 when in the first state, and after the insert plate 43 rotates, the end portion of the insert plate 43 is easier to be inserted into the anti-falling hole 31.
The usage method of the anti-falling stacker 100 of the utility model is as follows:
When the anti-falling stacker 100 works normally, the plugboard 43 is in the first state and does not interfere with the anti-falling rack 3, and the driving component 2 drives the anti-falling component 4 to move up and down; if the chain 24 breaks, the pull rod 42 loses tension and moves downwards, and the support 41 moves downwards at a lower speed than the pull rod 42 due to the connection with the guide rail, and the spring 48 resumes to provide downward pushing force to the connecting block 45, so that the connecting block 45 moves downwards rapidly relative to the support 41; the connecting block 45 and the second rotating pin 47 drive the insert plate 43 to rotate, then the insert plate 43 is close to one end of the anti-falling frame 3 to rotate and insert into the anti-falling hole 31, the stop plate 44 supports the insert plate 43 according to the dead point principle, so as to prevent the support frame 41 from rotating relative to the anti-falling frame 3, and the anti-falling effect is realized.
The anti-falling stacker crane 100 can realize the anti-falling function, has quick response and short response distance when falling, is easy to install and is easy to maintain.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
