Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The embodiment provides a bale breaking box anti-falling device, and is mainly used for limiting a twistlock of a hoisting bale breaking box, preventing misoperation of operators, and causing unlocking of a locking state of the twistlock, and the bale breaking box falls from a bridge crane.

As shown in fig. 1, four corners of the unpacking box body 10 are fixedly provided with upright posts 11 extending upwards, wherein the top ends of the upright posts 11 are fixedly provided with locks 12, and the locks 12 are matched with twistlocks 13 of the bridge crane to realize lifting of the unpacking box body 10.

Specifically, in this embodiment, in order to insert the twist lock 13 into the lock 12 and complete locking, as shown in fig. 3 and 5, a locking cavity 123 is provided inside the lock 12, and a locking hole 121 that communicates with the locking cavity 123 is provided on a top wall of the lock 12, where the twist lock 13 is inserted downward into the locking cavity 123 through the locking hole 121, and then the twist lock 13 is rotated by 90 ° through a hydraulic system, so as to achieve locking of the twist lock 13 and the lock 12.

In order to prevent misoperation of operators and to cause rotation of the twist lock 13 to release the locked state, in the embodiment, an anti-falling device of the unbinding box is arranged, as shown in fig. 2 and 3, and comprises a plug hole 122 which is formed in the side wall of the lock 12 and is communicated with a locking cavity 123, wherein a push rod 4 capable of sliding transversely is arranged in the plug hole 122, the device further comprises a driving mechanism for driving the push rod 4 to slide transversely, when the twist lock 13 and the lock 12 are in the locked state, as shown in fig. 5, the driving mechanism drives the push rod 4 to move towards the side of the twist lock 13, a gap between the end part of the push rod 4 and the twist lock 13 is reduced, rotation of the twist lock 13 is prevented from releasing the locked state, and accordingly falling of the unbinding box body 10 can be prevented.

In order to enable the twistlock 13 to pass through the lock hole 121 and be inserted into the locking cavity 123, and then leave enough clearance for the twistlock 13 to rotate, in this embodiment, as shown in fig. 4, at this time, the driving mechanism drives the ejector rod 4 to slide to a side far away from the twistlock 13, so that a sufficient space is left between the end of the ejector rod 4 and the twistlock 13 for the rotation of the twistlock 13, and at the same time, the unbinding of the unbinding box body 10 and the twistlock 13 of the bridge crane can be achieved in this state.

In order to realize the transverse sliding of the ejector rod 4, in this embodiment, as shown in fig. 3, 4 and 5, a positioning plate 2 extending vertically downwards is fixedly arranged on the lower wall of the lock 12, a supporting seat 21 is fixedly arranged on the positioning plate 2, a connecting rod 3 hinged through a first rotary pin 22 is arranged on the supporting seat 21, wherein the supporting seat 21 is hinged with the middle part of the connecting rod 3, and the top end of the connecting rod 3 is hinged with the ejector rod 4 positioned outside the lock 12.

Through the above arrangement, when the connecting rod 3 rotates counterclockwise around the first rotating pin 22, as shown in fig. 4, the upper end of the connecting rod 3 moves to the side far away from the lock 12 at this time, and then the ejector rod 4 can be driven to slide to the side far away from the twist lock 13, and when the connecting rod 3 rotates clockwise around the first rotating pin 22, as shown in fig. 5, the ejector rod 4 moves to the side of the twist lock 13 and abuts against the side wall of the twist lock 13 in the locked state, so as to prevent the twist lock 13 from rotating in the locked state.

Specifically, in order to achieve connection between the ejector rod 4 and the connecting rod 3, in this embodiment, as shown in fig. 3 and fig. 6, a connecting plate 41 extending vertically downward is fixedly disposed on an outer wall of the ejector rod 4, a positioning hole 411 is disposed on the connecting plate 41, and a second rotating pin 31 passing through the positioning hole 411 is disposed at an upper end of the connecting rod 3, so as to achieve hinging of the connecting plate 41 and the connecting rod 3.

In order to ensure the lateral movement of the ejector pin 4 when the connecting rod 3 rotates about the first pin 22, in this embodiment, as shown in fig. 6, the positioning hole 411 is a longitudinally arranged waist-shaped hole, wherein the second pin 31 is inserted into the waist-shaped hole; when the connecting rod 3 turns around the first rotating pin 22, the height of the second rotating pin 31 changes, and the second rotating pin 31 can move up and down in the positioning hole 411 because the positioning hole 411 is a waist-shaped hole, so that the lateral movement of the ejector rod 4 is prevented from being interfered.

When the end of the ejector rod 4 abuts against the side wall of the twistlock 13 in the locked state to limit the rotation of the twistlock 13, in order to prevent the ejector rod 4 from moving, in this embodiment, as shown in fig. 7, the lower end of the connecting rod 3 is welded with an extension plate 5, a limiting hole 51 is formed in the extension plate 5, a threaded hole 23 is formed in the positioning plate 2, a rocker arm 6 penetrating through the limiting hole 51 is connected with the threaded hole 23 in a threaded manner, limiting plates 7 are fixedly arranged on the rocker arms 6 located on two sides of the limiting hole 51, and two limiting plates 7 are clamped on two sides of the extension plate 5 to ensure synchronous movement of the rocker arms 6 and the connecting rod 3.

The outer diameter of the specific limiting plate 7 is larger than the diameter of the limiting hole 51.

In order to prevent the connecting rod 3 from rotating around the first pivot pin 22 and driving the rocker arm 6 to rotate together, in this embodiment, as shown in fig. 7, the limiting hole 51 is a longitudinally arranged waist-shaped hole, so as to solve the above problem.

In order to facilitate the rotation of the rocker arm 6, in the present embodiment, the rocker arm 6 is provided in an L-shape.

In order to strengthen the strength of the positioning plate 2, in the present embodiment, as shown in fig. 4 and 5, a reinforcing plate 8 is welded to the bottom of the positioning plate 2, wherein the reinforcing plate 8 is also welded to the upright 11, preventing the positioning plate 2 from being deformed.

In the embodiment, the connecting rod 3 is longitudinally arranged, and the rocker arm 6 is arranged at the bottom end of the connecting rod 3, so that the position of the ejector rod 4 is conveniently adjusted by a bundling worker.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
