Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.

As shown in fig. 1-3, an automatic material frame clamp comprises a hanger rail 2, two clamping jaws 3 slidably connected to the hanger rail, a driving mechanism for driving the clamping jaws 3 to move along the hanger rail 2, and a locking switch.

The driving mechanism comprises a suspension rod 4, both ends of the suspension rod 4 are rotatably connected with a pull rod 41, one end of the pull rod 41 is rotatably connected with the upper part of the clamping jaw 3, and the top of the suspension rod 4 is in threaded connection with a hanging ring 42 so as to be conveniently connected with lifting equipment through the hanging ring 42.

Two guide rods 21 are fixedly connected to the hanger rail 2, and guide holes matched with the guide rods are formed in the hanger rod 21. The guide rod is T-shaped.

The guide rod 21 plays a role in guiding and a role in limiting and preventing separation, so that the distance between the suspender 4 and the hanger rail 2 is limited, and the suspender 4 is prevented from separating from the hanger rail 2.

In this embodiment, the bottom of the clamping jaw 3 is provided with a hook 31 for hooking the outer side wall of the cargo.

In this embodiment, the bottom of the hanger rail 2 is fixedly connected with a balance arm 7 for pressing the upper surface of the cargo, and the balance arm 7 is perpendicular to the hanger rail 2. The balance arm 7 is matched with the clamping jaw to press a plurality of edges of the goods, so that the goods are lifted and conveyed stably; another function is to facilitate the movement of the jaws.

The locking switch comprises a fixing part 5 fixedly connected to the suspender and a switch rod 6 rotatably connected to the hanger rail, an annular motion track is arranged on the fixing part 5, a convex shaft moving along the annular motion track is arranged at the top of the switch rod 6, and a driving element for forcing the convex shaft to move unidirectionally all the time along the annular motion track is connected to the hanger rail. In this embodiment, the protruding shaft makes clockwise motion around the circular motion track.

The circular motion track comprises a first motion track 51, a second motion track 52 and a third motion track 53, wherein the first motion track 51 and the third motion track 53 are both in an inclined plane shape, the second motion track 52 is provided with a bracket 55 for supporting and placing the protruding shaft, the second motion track on the inlet side of the bracket is an inclined plane, and the second motion track on the outlet side of the bracket is a vertical straight plane.

In this embodiment, the fixed portion above the entrance of the second motion track 52 has an anti-slip block, and the anti-slip block has a fourth motion track 54 parallel to the first motion track, so that after the protruding shaft is separated from the first motion track 51, the fourth motion track 54 forces the protruding shaft 41 to enter the second motion track 52.

When the protruding shaft moves along the circular motion track, the locking switch has the following working modes:

the first working mode is as follows: the device is moved above the goods 1, the balance arm 7 is propped against the upper surface of the goods 1, the suspender 4 is pressed downwards, the suspender 4 pushes the two clamping jaws 3 to move reversely to the outermost end of the hanger rail 2 through the pull rod 41, and at the moment, the convex shaft of the switch rod 6 moves obliquely upwards along the track of the first moving rail 51.

The second working mode is as follows: after the boom 4 is depressed until it cannot, i.e. the protruding axis is out of the first motion trajectory 51 and contacts the fourth motion trajectory 54, at this time, the boom 4 is lifted by the lifting device, under the gravity of the cargo 1, the hanger rail 2 moves downward relative to the hanger rod, and the fourth motion track 54 forces the protruding shaft to enter the second motion track 52, which, in this embodiment, in the first mode of operation, the gripper 3 is at a distance from the surface of the load 1, so that after the protruding shaft has entered the second trajectory of motion 52, under the action of gravity of the goods 1, the convex shaft firstly moves downwards along the inclined plane of the second motion track 52 in an inclined way until the convex shaft enters the clamping groove 55 in the second motion track 52 and keeps still, the convex shaft moves downwards in an inclined way until the convex shaft enters the clamping groove 55, the clamping jaws 3 are not contacted with the surface of the goods 1, when the protruding shaft enters the slot 55, the clamping jaw 3 clamps the side wall of the cargo 1 and maintains the state.

The third working mode is as follows: after the cargo 1 is conveyed to a designated position, the suspension rod 4 is pressed downwards until the suspension rod cannot be pressed downwards, the protruding shaft rises along the vertical straight surface of the second motion track 52, enters the third motion track 53 under the action of the tension spring 43, moves downwards along the third motion track 53 in an inclined mode under the action of the gravity of the cargo 1 until the clamping jaw 3 is separated from the surface of the cargo 1, and then is separated from the third motion track 53 and enters the first motion track 51 under the action of the tension spring 43.

The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention has been disclosed by the preferred embodiment, it is not limited to the present invention, and any person skilled in the art can make modifications or changes equivalent to the equivalent embodiments by utilizing the above disclosed technical contents without departing from the technical scope of the present invention, but all the modifications, changes and changes of the technical spirit of the present invention made to the above embodiments are also within the scope of the technical solution of the present invention.
