Description
Technical field
Utility model belongs to Hoisting Security technical field, particularly relates to a kind of Novel hook safety device.
Background technology
Crane hook, when rising towards top fixed structure, will have the self-braking function of the action that suspension hook can be made to increase, to prevent the generation of hoisting rope overwind trouble.The realization of this function is typically to arrange a stopping means and realizes, and stopping means is to judge whether suspension hook puts in place by the degree of tightness of connecting line between weight and limit switch；Traditional design is that weight is held up and connecting line is fluffed by the pulley of suspension hook, and suspension hook stops rising by when suspension hook rises.But this kind of design is easy to be stuck in the steel wire rope gap with pulley at weight and weight when of with pulley contact, thus damage steel wire rope, even cause security incident.
Utility model content
This utility model mainly solves the technical problem existing for prior art, it is provided that a kind of Novel hook safety device, by more safe and reliable with the process that the change of weight contact portion makes height under hook spacing to suspension hook.
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals:
A kind of Novel hook safety device of the present utility model, including the first lateral pin, the second lateral pin, limited heavy hammer, connection flexible cord and limit switch；The two ends of the first lateral pin and the second lateral pin are separately fixed on two side plates of suspension hook, and the first lateral pin and the second lateral pin be arranged in parallel and holding level；Being provided with double bolt between the first lateral pin and the second lateral pin, one end of double bolts is flexibly connected with the first lateral pin, and the other end is overlapped on the second lateral pin；Described limit switch is arranged on the suspension bracket above suspension hook, and limited heavy hammer is connected with limit switch by connecting flexible cord, and limited heavy hammer is enclosed within the hoist rope of suspension hook and fixes the top holding above and being positioned at double bolts；Hoist rope is fixed end gap between two jaws of double bolts and is passed.
Further, one end that double bolts and the first lateral pin are flexibly connected is provided with sleeve pipe, and casing pipe sleeve is on the first lateral pin so that double bolts level can slide and rotate around the first lateral pin on the first lateral pin.
Further, the diameter 10mm of end is fixed in the gap between two jaws of described pair of bolt more than hoist rope.
Further, one end of double bolts and the second lateral pin overlap joint is opening, in fork-shaped.
The beneficial effect of utility model include following some:
1) when limited heavy hammer contacts with suspension hook above double bolts, the form of contact is a plane, will not produce limited heavy hammer and be sandwiched in the situation of wedge-shaped crevice.
2) it is can to slidably reciprocate along the first lateral pin due to double bolts, so double bolts can adapt to this drift angle by sliding when hoist rope has drift angle in this direction, without producing rigid interference with hoist rope.
3) relatively big due to the distance of two lateral pins, and the opening of double bolt is the longest, has drift angle also will not have rigid interference with any part at this direction hoist rope.
4) it is opening, i.e. fork-shaped due to one end of double bolts, it is simple to the installation of hoist rope.
5) less due to the opening of double bolts, weight does not drop to the possibility at following pulley.
Due to above-mentioned advantage, security reliability of the present utility model greatly improves than traditional scheme.
Accompanying drawing explanation
In order to be illustrated more clearly that utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only some embodiments of utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of utility model a kind of Novel hook safety device；
Fig. 2 is the top view seen down over from suspension hook；
The schematic diagram that Fig. 3 this utility model works on suspension bracket.
Detailed description of the invention
Below in conjunction with the accompanying drawings the preferred embodiment of utility model is described in detail, so that the advantage of utility model and feature can be easier to be readily appreciated by one skilled in the art, thus the protection domain of utility model is made apparent clear and definite defining.
As shown in Figure 1-Figure 3, a kind of Novel hook safety device, including first lateral pin the 1, second lateral pin 2, limited heavy hammer 3, connect flexible cord 4 and limit switch 5；The two ends of the first lateral pin 1 and the second lateral pin 2 are separately fixed on two side plates 61 of suspension hook 6, and the first lateral pin 1 and the second lateral pin 2 be arranged in parallel and holding level；Being provided with double bolt 7 between the first lateral pin 1 and the second lateral pin 2, one end of double bolts 7 is flexibly connected with the first lateral pin 1, and the other end is overlapped on the second lateral pin 2；Described limit switch 5 is arranged on the suspension bracket 8 above suspension hook 6, limited heavy hammer 3 is connected with limit switch 5 by connecting flexible cord 4, limited heavy hammer 3 is provided with aperture, and the hoist rope that limited heavy hammer 3 is enclosed within suspension hook 6 by this aperture is fixed on end 9 and is positioned at the top of double bolt 7；Hoist rope is fixed end 9 gaps between two jaws 71 of double bolts 7 and is passed.
Further, one end that double bolts 7 are flexibly connected with the first lateral pin 1 is provided with sleeve pipe 72, sleeve pipe 72 is enclosed within the first lateral pin 1 that (sleeve pipe 72 and two jaws 71 have collectively constituted double bolt 7, the two is one-body molded), make double bolt 7 level can slide and rotate around the first lateral pin 1 on the first lateral pin 1, so double bolts can adapt to this drift angle by sliding when hoist rope has drift angle in the axial direction of the first lateral pin 1, without producing rigid interference with hoist rope, and the gap between the first lateral pin 1 and the second lateral pin 2 is much larger than the gap between double 7 two jaws 71 of bolt.
Further, the diameter 10mm of end 9 is fixed more than hoist rope in the gap between two jaws 71 of described pair of bolt 7, limited heavy hammer 3 will not be made again ensure that to come off from gap while hoist rope is well by property.
Further, one end of double bolts 7 and the second lateral pin 2 overlap joint is opening, in fork-shaped so that hoist rope is easily installed.
The when of use, just start limited heavy hammer 3 distant with the distance of suspension hook 6, connect the limited weight of flexible cord 43 under gravity to stretch, when elevator rotation makes the tache motorice of hoist rope move upward, suspension hook 6 moves upward, suspension hook 6 constantly reduces with the distance of limited heavy hammer 3 simultaneously, when this process persistently carries out and reach suspension hook 6 contacting with limited heavy hammer 3, limited heavy hammer 3 is held up certain altitude by the most double bolts 7, when making the connection flexible cord 4 between limited heavy hammer 3 and limit switch 5 relax, limit switch 5 is triggered, limit switch 5 sends signal to electric-control system, electric-control system controls elevator according to this signal and stops operating, steel wire rope and suspension hook 6 stop rising.
The above, the only detailed description of the invention of utility model, but the protection domain of utility model is not limited thereto, any change expected without creative work or replacement, all should contain within the protection domain of utility model.Therefore, the protection domain of utility model should be as the criterion with the protection domain that claims are limited.
