All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in the attached drawings 1-3, the present invention improves the existing container hanger 1, the existing hanger 1 is fixed with corner fittings of four corners of the container through the four corners, and then the steel wire rope is connected with the crane through the hanging rings 9 at the four corners of the hanger 1 for hoisting, the structure of the existing hanger 1 is not repeated here, and the following description focuses on the improvement of the hanger 1 in the present invention:
a telescopic shaft motor 2 is fixed in the middle of a hanger 1, and a telescopic shaft 3 of the telescopic shaft motor 2 can be stretched in the vertical direction. The upper surface of the middle part of the hanger 1 is provided with a flat plate 10, the flat plate 10 is fixed on the hanger 1 through bolts, the telescopic shaft motor 2 is fixed on the flat plate 10, and the telescopic shaft 3 is positioned below the flat plate 10. A flange A4 is fixed on the bottom end face of the telescopic shaft 3, an arc-shaped steel plate 5 is arranged below the flange A4, a circular plane area 6 is arranged in the middle of the arc-shaped steel plate 5, a flange B7 is fixed on the plane area 6, and the flange B7 is fixed with the flange A4. Preferably, the diameter of the flat area 6 is equal to the diameter of the flange B7, and the flat area 6 is fixed with the telescopic shaft 3 through the flange B7. Preferably, the telescopic shaft motor 2 is connected with a PLC controller, and the telescopic shaft 3 is controlled to move up and down through the PLC controller.
The arc-shaped steel plate 5 can be bent downwards or upwards through deformation. For example, the arc-shaped steel plate 5 is originally bent upwards, namely, is an arc-shaped plate protruding upwards, and when the plane area 6 in the middle is pressed downwards, the arc-shaped steel plate 5 can generate elastic deformation and is changed into downward bending, namely, the arc-shaped plate protruding downwards; when the plane area 6 is pulled upwards, the arc-shaped steel plate 5 is restored to an upwards convex arc-shaped plate due to deformation. The arc-shaped steel plate 5 is a steel plate with small thickness, and the thickness of the arc-shaped steel plate 5 is preferably 2-12 mm. The arc of the arc-shaped steel plate 5 is small, and the preferred arc is 0.05-0.25.
The width of the arc-shaped steel plate 5 is equal to that of the hanger 1, and the width direction of the arc-shaped steel plate 5 is consistent with that of the hanger 1. The front edge and the rear edge of the arc-shaped steel plate 5 are both downwards integrally connected with a plurality of claws 8, and the claws 8 are used for grabbing the edge of the top plate of the container.
The clamping jaws 8 are made of stainless steel and are integrally connected with the arc-shaped steel plate 5. The jaws 8 are divided into a vertical portion, which is a rectangular piece, and a curved portion, which is used to grasp the edge of the container roof, as shown in fig. 3. In order to increase the strength of the container, corrugated plates are generally used for the side wall plates of the container, so that the distance between the claws 8 arranged therein is equal to the distance between the corrugations on the side wall plates of the container, and the claws 8 are respectively positioned between the corrugations.
The hanging bracket is characterized in that hanging rings 9 are additionally arranged on the upper surface of the hanging bracket 1 except four corners, and the hanging rings 9 are symmetrically arranged on the front side and the rear side of the middle part of the upper surface of the hanging bracket 1. Preferably, two hanging rings 9 are symmetrically added to the front and the rear of the hanger 1.
The device of the invention is used as follows: each rings 9 on the upper surface of the hanger 1 are respectively connected with a steel wire rope, the steel wire ropes are connected with shackles, the shackles are connected with a crane, then the hanger 1 is placed on a container through the crane, four corners of the hanger 1 are respectively aligned to four corners of the container, four corners of the hanger 1 are embedded into corner pieces at four corners of the container and then locked together, and the processes can be controlled through a PLC. Then the telescopic shaft 3 of the telescopic shaft motor 2 is controlled to move downwards by the PLC controller, the arc-shaped steel plate 5 is started to be a steel plate protruding downwards, namely the front side and the back side of the arc-shaped steel plate 5 slightly tilt upwards, the two sides are high, the middle is low, the arc-shaped steel plate 5 is gradually close to the upper top plate of the container, the clamping jaws 8 in the front and the back of the arc-shaped steel plate 5 are respectively positioned at the front side and the back side of the upper top plate of the container, and the clamping jaws 8 are positioned between the corrugations of the side wall plates of the container, at the moment, the telescopic shaft motor 2 is controlled to rotate in the opposite direction, the telescopic shaft 3 moves upwards, the arc-shaped steel plate 5 starts to lift upwards, the arc-shaped steel plate 5 generates elastic deformation by upward lifting force, and becomes an upward protruding steel plate, because the arc-shaped steel plate 5 deforms, the clamping jaws 8 at the two sides are in a furled state, the clamping jaws 8 respectively grasp the edge lower surface of the top plate of the container, when the clamping jaws 8 have lifting force to the top plate, at the PLC controller controls the telescopic shaft motor 2 to stop, and then hoisting normally. When needs are unloaded, 3 downstream of PLC controller control telescopic shaft, 3 downstream of telescopic shaft push down arc steel sheet 5 gradually, and arc steel sheet 5 receives the pushing down force and produces elastic deformation, when arc steel sheet 5 becomes the convex steel sheet down again because deformation, at this moment the jack catch 8 at preceding back edge is because the deformation of arc steel sheet 5 is outwards stretched, jack catch 8 unclamps the roof edge of grabbing, then normally unload can.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; those of ordinary skill in the art will understand that: the technical solutions described in the above embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
