Description

Become Duo plate-like articles suspender

Technical field

The utility model relates to a kind of hoisting tool for crane, especially a kind ofly is applicable to that handling becomes the suspender of Duo multi-disc plate-like articles, belongs to lifting handling machinery field.

Background technology

In steel plate originating firm, warehouse, goods yard, the mode that crane commonly used is hung steel rope lifts steel plate or various plate-like articles, because plate-like articles poor rigidity, area are big, is easy to during lifting the article slippage occur, causes equipment and personal injury accident.China utility model patent ZL 94228913.7 provides a kind of automatic clamping Steel plate hoisting implement, uses hydraulic oil cylinder driving, needs 2 people to operate.ZL 94214592.5 provides a kind of automatic folding Steel plate hoisting implement, utilizes double rocker mechanism to drive 4 suspension hook wedging steel plates.Above-mentioned two kinds of patent structures are comparatively complicated, generally can only be used for the steel plate of handling monolithic thickness, then can't handling for the sheet steel of rigidity deficiency or plate-like articles, and Applicable scope is narrower.

Summary of the invention

The purpose of this utility model provides a kind of production efficiency height, and is simple in structure easy to operate, safe and reliable, can once become to pile up neatly handling all thickness steel plate, or the suspender of other plate-like articles.

The technical solution of the utility model is: become Duo plate-like articles suspender, be made up of base, left jig arm, right jig arm, jig arm axle, connecting rod, pitman shaft, hanger, shackle shaft, axle sleeve, clamping plate suspension hook, clamping plate hinge, T type hook, Hook, position-limitting pin.Box bed end face center has T slot, four jiaos are provided with overhanging supporting arm with holes, left and right jig arm is provided with 3 groups of holes, upper, middle and lower, mider hole is hinged by jig arm axle and base support arm, the hole on left and right jig arm top is hinged with pitman shaft with an end of respective link respectively, the other end of each connecting rod is hinged with shackle shaft, the articulated hanger in shackle shaft middle part and with base on the Hook of band T type hook of T slot coupling, the clamping plate suspension hook is hinged with the underpunch of left and right jig arm with the clamping plate hinge.

Described Hook is a sleeve-shaped, and the upper end is provided with and the fraising of shackle shaft pivotally attached, and the lower end is fixed with one handle with the coaxial socket of cylindrical end running-fit of T shape hook and to T shape hook axial location on the T shape hook.

Being with a series of axle sleeves on shackle shaft separates each part of shackle shaft pivotally attached and axial location; 0～90 ° of rotation station of T shape hook handle respectively is provided with a location pin relatively on Hook.

The suspender hanger is hung on the suspension hook of crane, turning handle makes T shape link up with the T slot that blocks on the base, and left and right jig arm by gravity drive this moment clamping plate suspension hook opens, and hoist lifting hook rises, directly tangle base by T type hook suspender is hung away, but can not mention article.If turning handle is thrown off T shape hook and the T slot on the base, when hoist lifting hook rose, shackle shaft drove left and right jig arm by connecting rod and rotates in opposite directions around the jig arm axle that is fixed on the base, drove in the clamping plate suspension hook to receive, and clamped and catch on to wait to hang article it is mentioned.

The beneficial effects of the utility model are: hanger structure is simple, good rigidly, and cost is low.By the rotation of T shape hook with respect to Hook, loosen or clamp article to be hung, easy to operate, safe and reliable.Both can hang plate iron, become the buttress plate-like articles, can the various box-shaped article of handling, wide application, commonality is good.

Fig. 2 is the embodiment scheme drawing of the utility model suspender mode of operation.

Fig. 3 is the embodiment scheme drawing of the utility model suspender hook portion separation structure.

Among the figure: 1. base, 2. left jig arm, 3. right jig arm, 4. jig arm axle, 5. connecting rod, 6. pitman shaft, 7. hanger, 8. shackle shaft, 9. axle sleeve, 10. clamping plate suspension hook, 11. clamping plate hinge, 12.T type hook, 13. Hooks, 14. tommys, 15. one-tenth buttress plate-like articles, 16.T shape groove, 17. supporting arms.

The specific embodiment

Referring to each figure, box bed end face center has T slot 16, four jiaos are provided with overhanging supporting arm with holes 17, left and

right jig arm

2,3 is provided with 3 groups of holes, upper, middle and lower, mider hole is hinged with the supporting arm 17 of base 1 by jig arm axle 4, the hole on left and

right jig arm

2,3 tops is hinged with pitman shaft 6 with an end of respective link 5 respectively, the other end of each connecting rod 5 is hinged with shackle shaft 8, Hook 13 and hanger 7 are fixed on shackle shaft 8 centers, separate and axial location with axle sleeve 9, clamping plate suspension hook 10 usefulness clamping plate hinge 11 is hinged with the underpunch of left and right jig arm 2,3.The coaxial socket of cylindrical end running-fit of Hook 13 lower ends and T shape hook 12, and T shape linked up with 12 axial location can make T shape hook 12 rotational around Hook 13 by handle, and linking up with 11 slewing area with tommy 14 restricted T types is 0～90 °.

Suspender hanger 7 is hung on the suspension hook of crane, turning handle makes T shape hook 12 T slots 16 that block on the base 1, left and

right jig arm

2,3 by gravitys drive this moment clamping plate suspension hook 10 opens, hoist lifting hook rises, directly tangling base 1 by T type hook 12 hangs away suspender, but can not mention article, as shown in Figure 1.

Suspender is aimed at waited to hang into the decline of buttress plate-like articles 15 centers, contact with top surface to be hung until suspender base 1 lower surface, 90 ° of turning handles, T shape hook 12 and the T slot 16 on the base 1 are thrown off, when hoist lifting hook rose, shackle shaft 8 drove left and

right jig arm

2,3 by connecting rod 5 and rotates in opposite directions around the jig arm axle 4 that is fixed on the base 1, drives receipts in the clamping plate suspension hook 10, clamp and catch on and wait to hang into buttress plate-like articles 15 it is mentioned, as shown in Figure 2.Because clamping plate suspension hook 10 is hinged on the left and

right jig arm

2,3, can rotate automatically in the clamping process and adjust the position, make the inner plane of clamping plate suspension hook 10 be adjacent to into buttress plate-like articles 15 surfaces, under the squeezing action of clamping plate suspension hook 10, can will become buttress plate-like articles 15 piles neat, effectively prevent the deflection of upper strata article, make that lifting is more safe and reliable.
