Abstract
The utility model discloses a lifting hook, mainly comprising an upper pulley bracket, an upper pulley in the upper pulley bracket, a lower pulley bracket below the upper pulley bracket, two lower pulleys arranged inside the lower pulley bracket at two sides separately, and a lifting hook bracket and a lifting hook body connected to the lower part of the lower pulley bracket, wherein the upper end, at two sides of the upper pulley, of the upper pulley bracket is connected with wall rods vertically arranged at the lower parts of two lateral walls of the lower pulley bracket through pin shafts, respectively; bolts capable of being inserted into inserting holes in the lower pulley bracket from two sides are transversely formed in the lower parts of the two wall rods, respectively; the upper end parts of the two wall rods are connected with impact rods which are upwards crossed, respectively. Therefore, the lifting hook has the characteristics of being simple in structure, convenient and reliable in use, good in safety and the like, and can effectively play a role of lifting a heavy object.
Description
Technical field
The utility model relates to for the load hook on hoisting crane, belong to elevator machinery technical field.
Background technology
During current crane hanging component weight, by the pulley on lifting rope connecting shackle, realize moving up and down of hook, existing a kind of hook member mainly contains: top sheave support, be arranged on the top sheave on top sheave support, lower sheave support, splits two lower sheaves on both sides on being arranged between lower sheave, and the suspension hook support and the hook that are connected to lower sheave support below; According to the multiplying power of load hook, be load hook hang the different of load carrying ability and lineoutofservice signal pull ratio, steel rope is by the different wire rope handling modes that adopt between upper lower sheave, above-mentioned lifting rope is through forming the multiplying power of twice after two lower sheaves, then the lifting rope after process top sheave can obtain the multiplying power of 4 times.In actual use, be not that the multiplying power of load hook is the bigger the better, best is to adapt with the weight of lifting.Therefore, existing load hook needs conveniently to regulate the multiplying power of load hook, to bring into play best lifting effect; But existing other similar suspension hook will reach the adjustable of multiplying power, and structure is often very complicated, but also can affect the safety of lifting.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of improvement of carrying out on prior art basis is provided, and makes it have simple in structurely, easy to use and reliable, and safety is good, can bring into play preferably the load hook of weight lifting effect.
The purpose of this utility model completes by following technical solution, it mainly comprises: a top sheave support, a top sheave being arranged in top sheave support, one is positioned at the lower sheave support of top sheave support below, two lower sheaves that are arranged in lower sheave support and split both sides, one is connected to suspension hook support and the hook of lower sheave support below; The top sheave support upper end of described top sheave both sides is placed in the wall bar of lower sheave support two side under being connected with vertically by a bearing pin respectively, the bottom of two wall bars is horizontally arranged with respectively and can be plugged in the latch in lower sheave support spliced eye from both sides, and the upper end of two wall bars is connected to respectively upwards and the drop bar of arranged crosswise.
On the both sides lower sheave support of described two lower sheaves, be respectively arranged with circular arc slant handle; Bearing pin connecting shackle support is passed through in the bottom of lower sheave support, and by a crossbeam, connects described hook in suspension hook support bottom.
The utility model belongs to a kind of improvement to prior art, and it has simple in structure, easy to use and reliable, and safety is good, can bring into play preferably the features such as weight lifting effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1,2, load hook described in the utility model, it mainly comprises: a top sheave support 1, a top sheave 2 being arranged in top sheave support 1, one is positioned at the lower sheave support 3 of top sheave support 1 below, two lower sheaves 4, that are arranged in lower sheave support 3 and split both sides are connected to suspension hook support 5 and the hook 6 of lower sheave support 3 belows; Top sheave support 1 upper end of described top sheave 2 both sides is connected with respectively the wall bar 8 of lower sheave support 3 two sides that are vertically placed in by a bearing pin 7, the bottom of two wall bars 8 is horizontally arranged with respectively the upper end that can be plugged in from both sides latch 10, the two wall bars 8 in lower sheave support 3 spliced eyes 9 and is connected to respectively upwards and the drop bar 11 of arranged crosswise; When lifting rope rises whole suspension hook and move to car body bottom and make the upper end of two drop bars strike car body bottom, two drop bars are stressed moving down respectively, the two wall bars that are attached thereto outwards open centered by bearing pin, at this simultaneously, latch on two wall bars comes off thereupon, lower sheave support and top sheave support are separated, at this time lower sheave is inoperative for lifting rope, lifting rope is directly by two lower sheaves, thereby realize 4 times of multiplying powers that switch to the load hook of 2 times, to meet and meet the needs of actual hoisting heavy.
The utility model is respectively arranged with circular arc slant handle on the lower sheave support of the both sides of described two lower sheaves; Bearing pin connecting shackle support is passed through in the bottom of lower sheave support, and by a crossbeam, connects described hook in suspension hook support bottom.
Claims (2)
1. a load hook, it mainly comprises: a top sheave support, a top sheave being arranged in top sheave support, one is positioned at the lower sheave support of top sheave support below, two lower sheaves that are arranged in lower sheave support and split both sides, one is connected to suspension hook support and the hook of lower sheave support below; The top sheave support upper end of the top sheave both sides described in it is characterized in that is placed in the wall bar of lower sheave support two side under being connected with vertically by a bearing pin respectively, the bottom of two wall bars is horizontally arranged with respectively and can be plugged in the latch in lower sheave support spliced eye from both sides, and the upper end of two wall bars is connected to respectively upwards and the drop bar of arranged crosswise.
2. load hook according to claim 1, is characterized in that being respectively arranged with circular arc slant handle on the both sides lower sheave support of described two lower sheaves; Bearing pin connecting shackle support is passed through in the bottom of lower sheave support, and by a crossbeam, connects described hook in suspension hook support bottom.
