Description

Lifting hook and automatic hanging and releasing beam

Technical Field

The invention belongs to the technical field of automatic hanging and releasing beams, and particularly relates to a lifting hook and an automatic hanging and releasing beam.

Background

In the fish elevator system, the fish catching grid needs to be lifted to a certain height in the process of entering a fish collecting corridor by fish shoals, and the process is realized by an automatic grabbing beam. The realization mode of automatic grabbing beam that adopts at present has three kinds, and is first, and the roof beam is grabbed to hydraulic pressure, grabs the roof beam like patent "a hydraulic pressure, patent number: CN210507454U "; the second kind, the automatic string of pneumatic disengaging beam, like the patent "the automatic string of pneumatic disengaging beam, patent number: CN206052657U "; and thirdly, a weight type automatic grabbing beam.

The hydraulic beam grabbing mode controls a hydraulic system to drive the plug pin to stretch back and forth through an electric system, and therefore automatic grabbing and releasing of the grabbing beam are achieved. However, because it involves a plurality of system devices such as electric, hydraulic and mechanical transmission systems, the device is expensive in cost and difficult to maintain. And the leakage of hydraulic oil in the hydraulic system can pollute river water, so the application of the hydraulic grabbing beam in the fish elevator system is gradually banned.

The automatic beam hanging and releasing mode of air pressure controls the movement of a cylinder piston through an electric control system, and then drives a bolt to move to complete pin transferring and pin releasing actions.

The heavy hammer type automatic grabbing beam can realize automatic grabbing but cannot realize automatic unhooking, unhooking can be realized only by manually pulling the heavy hammer from one side to the other side, the operation is very inconvenient, manual participation is required, and the labor cost in the operation process is increased.

Unhooking process: as shown in fig. 5, the hanging ring is in the hook 33 of the hook 3 in the hanging state, and the lower cross bar 43 is above the baffle 5 and on the inclined surface 221 side. When unhooking, the lifting hook moves downwards, so that the side wall of the lower section of the hook 3 is in contact with the lifting ring of the fish catch fence, and the lifting ring of the fish catch fence can not move in the contact process of the hook 3 because the position of the fish catch fence is fixed. The hook 3 is pushed by the fish catch lifting ring to swing towards the front of the side plate 1, at this time, as shown in fig. 6, the hook 3 pushes the push-pull rod 4, so that the lower cross rod 43 moves from the baffle 5 to the inclined surface 221 and enters the clamping groove 222 along the inclined surface. When the lower cross bar 43 is clamped at the position of the clamping groove 22 as shown in fig. 7, the push-pull rod 4 fixes the position of the hook 3, and at the moment, the hanging ring of the fish catching grid and the hook part 33 have a preset interval in the horizontal direction, so that the unhooking process is completed.

Hanging and taking processes: the lower cross bar 43 remains lodged in the pockets 22 before being hung. Firstly, the lifting hook is lowered, as shown in fig. 8, the lifting ring of the fish catching grid is used again to push the lower section of the hook 3, so that the hook 3 continuously swings to a preset angle towards the front of the side plate 1, and the lower cross rod 43 enters the vertical section of the recovery groove 223 behind the guide plate 2; as shown in fig. 9, the hook is lifted after the lower rail 43 smoothly enters the recovery tank 223. At this moment, the hook 3 loses the supporting force of the fish catch grid hanging ring, the hook 3 swings towards the rear of the side plate 1 under the action of gravity, the lower cross rod 43 moves towards the baffle 5 along the recovery groove 223 as shown in fig. 10, then the baffle 5 is pushed to continue moving upwards until the lower cross rod 223 crosses the baffle 5, the hook 3 is in a natural sagging state at this moment, the hook part 33 is just positioned under the fish catch grid hanging ring, the lifting hook continues to move upwards, and the fish catch grid hanging ring is smoothly clamped into the hook part 33 as shown in fig. 5, so that the hanging process is completed.
