The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.Should be understood that the specific embodiment described herein only is used for description and interpretation the utility model, is not limited to the utility model.
The multiplication-variable hook device that the utility model provides, comprise running block 1, fixed pulley group 2, steel rope 3 and suspension hook 4, described running block 1 comprises a plurality of movable pulleys 11, movable pulley axle 13 and first adapter plate 12, described a plurality of movable pulley 11 is assemblied between two described first adapter plates 12 by described movable pulley axle 13, described running block 2 is connected with described suspension hook 4, described steel rope 3 twines described fixed pulley group 2 and is connected to described running block 1, wherein, described first adapter plate 12 is provided with groove 14, described movable pulley axle 13 can move in the described groove 14 and by stop part 15 and be positioned on described first adapter plate 12, and can move and leave described first adapter plate 12 along described groove 14, described stop part 15 removably be connected with described first adapter plate 12.
In the prior art, two ends that are used for movable pulley axle 13 are contained in the mounting hole that is opened on first adapter plate 12 usually, and in according to cargo hook gear of the present utility model, as shown in Figure 1, the part that is used for carrying movable pulley axle 13 of first adapter plate 12 is set to groove 14.In this way, when needs conversion multiplying power, only need pull down the stop part 15 for the end of location movable pulley axle 13, then movable pulley 11 be taken out from groove 14 together with movable pulley axle 13, can carry out lanyard easily and get the rop exercise work.Therefore, adopt cargo hook gear of the present utility model, can carry out any conversion to multiplying power.
Mobile vertically in groove 14 in order to limit movable pulley axle 13, preferably, can be arranged with back-up ring 16 in the end of movable pulley axle 13.Back-up ring 16 and stop part 15 can form suitable form arbitrarily.As preferred embodiment a kind of, the part of the outer peripheral face of back-up ring 16 can form the plane, and stop part 15 can be resisted against on this plane.Like this, can contact by formation face between back-up ring 16 and the stop part 15, thereby make movable pulley axle 13 more stable, and can reduce the wearing and tearing of back-up ring 16 and stop part 15 effectively.Particularly, be connected with detouchable between first adapter plate 12 for stop part 15, can adopt modes such as bolt connection.
Preferably, described multiplication-variable hook device can also comprise fag end holding element 5, and this fag end holding element 5 selectively is connected on described running block 1 or the described fixed pulley group 2.By fag end holding element 5 is set, can be the more fixing fag end of steel rope 3.When fag end holding element 5 is connected on the running block 1, can be implemented in conversion multiplying power between the odd number multiplying power; When fag end holding element 5 is connected on the fixed pulley group 2, can be implemented in conversion multiplying power between the even number multiplying power.
Particularly, as shown in Figure 2, described fixed pulley group 2 comprises second adapter plate 22 and a plurality of fixed pulley 21, and described a plurality of fixed pulleys 21 are assemblied between two described second adapter plates 22.Preferably, fixed pulley group 2 can also comprise a plurality of sheaves 23, and these a plurality of sheaves 23 are assemblied between two described second adapter plates 22.By sheave 23 is set, can provide guiding and tensioning to steel rope 3.
As preferred embodiment a kind of, the centre plane of described sheave 23 can be angled with the centre plane of described fixed pulley 21.By making the two pulley center mask of fixed pulley 21 and sheave 23 that an angle be arranged, can avoid 3 pairs of steel ropes above-mentioned both produce axial force, to prolong the service life of fixed pulley group 2.
For steel rope 3 is navigated on the corresponding sheave more accurately, described fixed pulley group 2 can also comprise a plurality of twine guide plates 24.Particularly, the side opposite with described a plurality of fixed pulley 21 that these a plurality of twine guide plates 24 can be installed in described sheave 23 by a plurality of twine guide plate anchor shafts 26, the radially extension of each twine guide plate from the wheel rim of the sheave of correspondence along this corresponding sheave, and around the part of the circumference of the sheave of described correspondence.More specifically, can also be provided with fag end anchor shaft 25 on the fixed pulley group 2, when adopting the even number multiplying power, this fag end anchor shaft 25 can be used for supporting fag end holding element 5.
Because cargo hook gear is applied in the hoisting crane usually, steel rope 3 interferes with other parts during for fear of the arm luffing of hoisting crane, preferably, described fixed pulley group 2 can also comprise that the 3rd adapter plate 27, the three adapter plates 27 are connected with described second adapter plate, 22 pivots at described fixed pulley 21 1 ends of being equipped with of described second adapter plate 22.Particularly, multiplication-variable hook device of the present utility model is installed on the arm by the 3rd adapter plate 27
The number of the various pulleys in the cargo hook gear of the present utility model can be set as required, for example, the quantity of fixed pulley 21 and movable pulley 11 all can be set at 5, the quantity with sheave is set at 4 simultaneously, and then the multiplying power of cargo hook gear can be in the scope inner conversion of 1-10 at this moment.
The utility model also provides a kind of hoisting crane, and multiplication-variable hook device as indicated above is installed on the arm of this hoisting crane.
The working process of the multiplication-variable hook device that brief description once the utility model proposes.
With reference to figure 3, when cargo hook gear need adopt the odd number multiplying power, fag end holding element 5 is installed on first adapter plate 12, the fag end of steel rope 3 is fixed in the fag end holding element 5.This moment be if will increase multiplying power, then takes off steel rope and it is suspended on the running block 1 from the fixed pulley group 2 that is wound with steel rope 3; If will reduce multiplying power, then take off steel rope on the follow-up pulley group 1, start the steel rope that takes off behind the elevator and automatically retract on the fixed pulley group 2 by twine guide plate 24, realize conversion between the odd number multiplying power easily with this.Fig. 4 shows that cargo hook gear is in the state of four multiplying powers, and this moment, cargo hook gear can conversion between the even number multiplying power, and its working process is identical with the conversion of odd number multiplying power, does not repeat them here.
Below describe preferred implementation of the present utility model by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in the above-mentioned embodiment; in technical conceive scope of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
Need to prove that in addition each the concrete technical characterictic described in the above-mentioned specific embodiment under reconcilable situation, can make up by any suitable manner.For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible array modes.
In addition, also can carry out combination in any between the various embodiment of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
