The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figures 2 and 3, present embodiment has the revetment block lifting appliance of automatic releasing hook function, comprise crane, wire line hitch 1 and shackle 2, crane has hook 3, and wire line hitch 1 one ends link to each other with hook 3, and the other end links to each other with shackle 2, lifting appliance also comprises handling hook 6, handling hook 6 is by coupler body 61 and tiltedly hang handle 62 and connect and compose, and coupler body 61 and the junction 63 of tiltedly hanging handle 62 are articulated in shackle 2, and coupler body 61 departs from lifting vertical axis L when empty handling.
Particularly, handling hook 6 in the present embodiment adopts the steel plate forming of suitable thickness, its concrete size should be decided by lifting revetment block tonnage under the prerequisite of safety lifting, guarantee tiltedly to hang the quality of the quality of handle 62 greater than coupler body 61, according to lever principle, coupler body 61 is when empty handling, when promptly coupler body 61 does not bear the pulling force of revetment block 4, can depart from lifting vertical axis L, make it hang in nose 5 holes from revetment block 4.Handling hook 6 is hinged with shackle 2, can adopt penetrating lifting hole(eyelet) 64 is set on junction 63, shackle 2 can be a bow shackle in the present embodiment, or conventionally form such as D type shackle, it has locking bearing pin 21, handling hook 6 is articulated on the locking bearing pin 21 with the lifting hole(eyelet) place, and the end that locking bearing pin 21 has a screw thread lock onto in the eye of shackle 2 easy installation and removal after passing the lifting hole(eyelet) 64 of handling hook 6.Certainly, shackle 2 also can be adopted other form, and present embodiment is not done concrete restriction to this.
Present embodiment has the revetment block lifting appliance of automatic releasing hook function, by setting up the handling hook, the handling hook is by tiltedly hanging handle and coupler body is formed by connecting, and be articulated in shackle in the junction, coupler body departs from the lifting vertical axis when empty handling, then make handling be hooked in the non-stress state that handling finishes, coupler body rotates automatically and raises up, hang in the nostril from revetment block, realize automatic releasing hook, need not artificial decoupling device operation, safe and reliable, improved the work efficiency of decoupling device speed and this crane ship group greatly.
Based on technique scheme, optionally, the crotch opening of coupler body 61 is inwardly towards tiltedly hanging handle 62, the orientation is to depart from the direction of lifting by crane vertical axis L with coupler body 61 to define herein, with the hinge-point is the boundary, handling hook 6 is when empty handling, coupler body 61 is to the direction motion of lifting by crane vertical axis L away from hinge-point below part, i.e. outwards motion is tiltedly hung 62 of handles near being the direction motion that coupler body 61 hinge-points below part is lifted by crane vertical axis L, i.e. inwardly motion, the crotch opening of only guaranteed coupler body 61 is inwardly towards tiltedly hanging handle 62, in the time of just making coupler body 61 skews, its crotch just can be in the state that hangs nose 5 away from revetment block 4, thereby realizes breaking off relations.
Break off relations in the handling process, being convenient to handling hook 6, tiltedly hang handle 62 and can not push shackle 2 and wire line hitch 1, coupler body 61 with tiltedly hang handle 62 and bend and be connected.
When making coupler body 61 depart from lifting vertical axis L, its crotch can be fully from revetment block 4 hang in nose 5 holes, coupler body 61 is 125 °～155 ° with the deviation angle α of lifting vertical axis L when empty handling, is advisable with 135 ° in the present embodiment.
In the present embodiment, coupler body 61 is relevant with the quality difference size of tiltedly hanging handle 62 and coupler body 61 with the deviation angle α of lifting vertical axis L when empty handling, if the two quality differs bigger, according to lever principle, then the α value is bigger.If deviation angle α is too small, the quality of promptly tiltedly hanging handle 62 and coupler body 61 differs too little, can make the crotch of coupler body 61 can not be fully from revetment block 4 hang in nose 5 holes, influence next working cycle, then should the two quality size of reasonable disposition.
Based on technique scheme, optionally, be the forming process of simplifying handling hook 6, coupler body 61 with tiltedly hang handle 62 and be formed in one.
Particularly, handling hook 6 integral body can adopt casting to wait the metal forming mode, and the molding mode of present embodiment handling hook 6 is not done concrete restriction, and are whole one-body molded, simplified forming process, improved production efficiency.
The handling installation and the automatic releasing hook process of revetment block lifting appliance that present embodiment has the automatic releasing hook function is as follows:
The square barge of filling revetment block 4 rests in the outer slope of harbour and prepares to install revetment block 4, hang wire line hitch 1 on the suspension hook 3 of crane on side's barge, the other end of steel wire buckle 1 is connected with lifting hole(eyelet) 64 on the handling hook 6 by the locking bearing pin 21 of shackle 2, handling hook 6 is hinged with shackle 2, can rotate around locking bearing pin 21.The crane man staff is tiltedly hanging handle 62, coupler body 61 is hung in the hole of hanging nose 5 of revetment block 4, do not loose one's grip simultaneously, and commander's crane plays hook, when the wire line hitch 1 on hanging over hoist lifting hook 3 is tightened up, determine that handling hook 6 can not be when hanging of revetment block 4 comes off in the nose 5, the lifting workman command crane to stop hook and transfer to safety zone fast after command crane to play hook block fortune revetment block again, tiltedly hang the upper position that handle 62 is positioned at shackle 2 this moment.Crane plays and begins off the hook after revetment block 4 runs to the installation site, after revetment block 4 lands, when handling hook 6 is no longer stressed, tiltedly hang handle 62 by gravitys turn to shackle 2 from the top of shackle 2 lower position, be that coupler body 61 is offset out lifting vertical axis L, come off out from hanging in the nose 5 of revetment block 4, turn to the upper position of shackle 2.After crane is laid down revetment block, next transfer to next working cycle.
It should be noted that at last: above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technical scheme.
