Description of the sequence numbers:
the device comprises an electromagnet 1, a bar bundle 2, a protective hook 3, hook feet 3-1, a hinge shaft 3-2, a bearing seat 3-3, a connecting rod 3-4, a sliding block 3-5, a hydraulic cylinder piston rod 4, a long cross beam 5, a short cross beam 6, a vertical beam 7, a connecting block 8, an electromagnet hook 9, a connecting through hole 10, a hydraulic cylinder 11, a hanging lug 12 and a hydraulic pump station 13.
Detailed Description
The invention will be described in more detail with reference to the following embodiments:
the present invention as shown in fig. 1 to 6 includes a support frame and a plurality of groups of electromagnets 1 uniformly distributed under the support frame, two pairs of protection hooks 3 for encircling a bar bundle 2 are arranged under the support frame between the electromagnets 1, each pair of protection hooks 3 is composed of two hook legs, the upper end of each hook leg 3-1 is hinged between a pair of bearing seats 3-3 through a hinge shaft 3-2, the upper end of each hook leg 3-1 is hinged with the lower end of a connecting rod 3-4, the upper end of the connecting rod is connected to a slider 3-5, the slider is fixedly connected with the bottom of a piston rod 4 of a hydraulic cylinder, when the hydraulic cylinder extends the piston rod downwards, the piston rod pushes the slider downwards, the connecting rod 3-4 hinged with the slider presses one end of the hook leg downwards, the other end encircling the bar bundle opens towards both sides, when the hydraulic cylinder retracts the piston rod upwards, the slider moves upwards, drives one end of the connecting rod upwards, the other end of the connecting rod pulls upwards, the lower end of the hook leg can encircle the bar bundle towards the middle, and under the condition of losing electricity, the bar bundle can not fall down; the support frame comprises two long cross beams 5 arranged at the lower part side by side and two short cross beams 6 arranged at the upper part side by side, and the long cross beams 5 are connected with the short cross beams 6 through vertical beams 7; connecting blocks 8 are fixedly arranged between the two long cross beams 5 at intervals, each connecting block 8 is provided with a connecting through hole 10 for connecting and fixing with an electromagnet hook 9, and the electromagnet hook 9 is connected and fixed with the electromagnet 1; a hydraulic cylinder 11 is arranged between the connecting blocks at the two ends and the adjacent connecting blocks, the hydraulic cylinder is arranged between the two long beams 5 through a hydraulic cylinder mounting plate 12, and the top ends of the bearing seats 3-3 are fixedly connected with the bottom surfaces of the long beams 5; two ends of the two short beams 6 are fixedly connected through connecting plates, four corners of the top ends of the two short beams are provided with hanging lugs 12, and a hydraulic pump station 13 is arranged on the long beam below the short beams.
The working process is as follows:
1. after the electromagnet sucks a bar bundle hanging object, the hanging object below the beam is lifted to a height so as to close the protection hook by the hoisting equipment, the hydraulic system controls the piston rod of the hydraulic cylinder to retract upwards, the piston rod drives the sliding block and the connecting rod to rise, the connecting rod pulls the upper end position of the protection hook, the lower end of the protection hook descends to the middle and is close, and the paired protection hooks hold the bar bundle.
2. The same reason, hoisting equipment descends after moving the hoisted object to the appointed position, after descending to the height that relative safety can open the protection hook again, hydraulic system control pneumatic cylinder piston rod stretches out downwards, the piston rod drives slider, connecting rod and then pushes down, the connecting rod is pressing the upper end position of protection hook, the lower extreme of protection hook is outwards opened, after the hoisted object targets in place, the electro-magnet release, hoisting equipment promotes the electromagnetism hoist and returns the normal position or carries out hoist and mount next time.
3. When the electromagnetic crane breaks down in the hoisting process, the hoisted objects fall onto the protective hooks, so that the risk that the hoisted objects fall from the high altitude is prevented.
