Abstract

Disclosed is a claw hook type hanger of a steelmaking slag pot. A center column is fixed at the center of a lower beam, the upper portion of the center column penetrates into a central through hole of an upper beam, a supporting frame and a supporting shaft are fixedly mounted above the upper beam, a hanging plate is sleeved on the supporting shaft, the lower portion of the center column is sleeved with a movable slide disc with upper and lower conical surfaces, a lock disc with inner and outer conical surfaces, which is located above the movable slide disc, is fixed on the center column via a pin shaft, conical degree of the upper conical surface of the movable slide disc is identical to that of the inner conical surface of the lock disc, diameters of bottom circles of the movable slide disc and the lock disc are identical, the middle of the lower side of the upper beam is hinged with two lock hooks with lower ends provided with hooks through pin shafts, a counter weight is arranged on the outer side of each lock hook, middles of four corner-shaped clamp legs are respectively hinged to two ends of each of front and rear side beams of the lower beam via pin shafts, the lower end of each clamp leg is hinged with a hook clamp plate, the lower end of a chain plate is hinged to the upper ends of the clamp legs, the upper end of the chain plate is hinged to the outer end of the lower side of the upper beam, and weight blocks are disposed on the upper portions of the clamp legs. The steelmaking slag pot can be assembled, disassembled automatically and hoisted, thereby not only increasing work efficiency and safety factors, but also reducing labor intensity of workers.

Description

Steel-making slag basin grapple formula suspender

Technical field

The crane accessory device that handling steel-making slag basin is used in a kind of steel industry.

Background technology

Steel industry often needs handling steel-making slag basin in smelting.The lifting to steel-making slag basin at present is still manual mode of operation, and promptly the operative employee is at first hooked the hook on four iron chains respectively four hanging holes on the steel-making slag basin, carries out handling with sling iron chains and steel-making slag basin of crane then.After handling puts in place, will link up with in steel-making slag basin hanging hole with manual method again and take off.This mode requires workman's close contact steel-making slag basin, and the workman is operated in temperature height, the dusty harsh environment, adds that labour intensity is big, and safety factor is low, threatens seriously that the workman's is healthy.There is the low defective of efficiency in addition.

Summary of the invention

The purpose of this utility model provides a kind of steel-making slag basin grapple formula suspender, accomplishes that folder hangs steel-making slag basin automatically, improves work efficiency, alleviates labor strength, improves working conditions.

Technical scheme is to be double-tee underbeam central authorities to be fixed with center mast, and center mast top is set in the upper beam center through hole, and the top of putting the beams in place is fixed with two bearing supports, between two bearing support tops bolster is housed, and the boatswain chair with lifting hole(eyelet) is enclosed within on the bolster; The center mast bottom is with up and down, and shape all is the movable sliding plate of the conical surface, the inside and outside shape that is positioned at movable sliding plate top all is that the lock collar of the conical surface is fixed on the center mast with bearing pin, the tapering of the conical surface and lock collar inner conical surface is identical and end circular diameter is the same on the movable sliding plate, middle side part is hinged with the latch hook of two lower end buckles under putting the beams in place by lock shaft, there is gravity block in the latch hook outside, four turning clevis midlegs respectively with bearing pin be hinged on underbeam before, on the back side bar two ends, the lower end of each leg lock is hinged with the hook clamping plate, the Chain plate lower end is hinged on the leg lock upper end, the Chain plate upper end is hinged on place, upper beam downside outer end, and the weightening finish stone roller is arranged at leg lock top.

Principle of work and using method are as follows: grasp steel-making slag basin if desired, hoist lifting hook at first descends the underbeam of general who has surrendered's suspender to be placed on the steel-making slag basin; Continue then to descend, because the action of gravity of suspender top self gravitation and gravity block, weight steelyard weight, latch hook is moved down into and slides to its conical surface down on the movable sliding plate behind the conical surface again, and four leg lock are opened, and is in and treats clamp position.Sling when crane and to put the beams in place when moving up, latch hook moves up thereupon.Latch hook elder generation drive activity sliding plate moves up along center mast, and is when movable sliding plate moves to and contacts with lock collar, no longer mobile.This moment, latch hook continued to move up along the conical surface under the movable sliding plate.Since on the movable sliding plate conical surface fit fully with the lock collar inner conical surface and outside dimensions the same, so latch hook will slip away the activity sliding plate and on move on on the lock collar male cone (strobilus masculinus), movable sliding plate then is slipped to the center mast bottom automatically and locates.At this moment crane continue to sling put the beams in place and latch hook along moving on the center mast, drive four leg lock toward intrinsic deflection by four Chain plates, four hook clamping plate then clamp and hook makes steel the slag basin, the slag basin of will making steel is sling.

When crane was walked steel-making slag basin stowed location, hoist lifting hook descended steel-making slag basin is fallen on the stowed location; When suspension hook continues to descend, because the action of gravity of suspender top self gravitation and gravity block, weight steelyard weight, upper beam moves down, and the latch hook of upper beam downside moves down between lock collar and the movable sliding plate along center mast, this moment, four leg lock were opened to extrinsic deflection, and four hook clamping plate unclamp from steel-making slag basin.If at this moment crane is sling to put the beams in place and moved up, latch hook will hook the lower end of lock collar so, make four leg lock keep open configuration and along with moving on the suspension hook, thereby make whole suspender leave steel-making slag basin, finish and unload the basin action.

Compared with the prior art, characteristics of the present utility model are automatic loading and unloading and handling steel-making slag basins, can operation under the big environment of high temperature, dust, both increased work efficiency and safety factor, and alleviate labor strength again, ensure that conscientiously the workman's is healthy.
