Detailed description of the invention

The object implemented for making the utility model, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, are further described in more detail the technical scheme in the utility model embodiment.In the accompanying drawings, same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Described embodiment is the utility model part embodiment, instead of whole embodiments.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the utility model, and can not be interpreted as restriction of the present utility model.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.

In description of the present utility model, it will be appreciated that, term " " center ", " longitudinal direction ", " transverse direction ", " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end " " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore the restriction to the utility model protection domain can not be interpreted as.

As shown in Figure 1, force direction is F, the tractor equipment that the traction angle that the utility model provides is adjustable comprises mounting seat 1 and is fixed on the dead sheave 2 in described mounting seat 1, also comprise a rotatable pulley 3 in order to adjusting angle simultaneously, the force side of described rotatable pulley 2 is connected by hauling rope with the stressed side of described dead sheave 2, and described hauling rope vertical and horizontal face, the chassis of described mounting seat 1 is provided with S. A. 5, be connected and fixed pulley to overlap with the line of centers of described S. A. with the perpendicular line at the hauling rope place of rotatable pulley, described rotatable pulley 3 is fixedly connected on described S. A. 5, and rotate around the line of centers of described S. A. 5.Due to the line of centers of S. A. 5 and the vertical line at hauling rope place described above, thus be actually the perpendicular line of rotatable pulley 3 between two pulleys to rotate, thus ensure that rotatable pulley is when rotating, dead sheave 2 can not change with the angle of draught line.The force side described in the present embodiment and stressed side is understood for clearer, think in the present embodiment, when the force side of described pulley refers to make this pulley rotation by hauling rope, hauling rope is initiatively applied to the side of power, when the stressed side of described pulley refers to make this pulley rotation by hauling rope, the driven stressed side of hauling rope, specifically as shown in Figure 1, the F in left side is because be apply power by artificial reason to dead sheave 2, therefore this side is dead sheave 2 and exerts a force side, and the F on the right side driven power being applied to goods that is rotatable pulley 3, therefore this side is the stressed side of rotatable pulley 3.

This gives a kind of connection mode of S. A. 5 and rotatable pulley 2, as shown in Figure 1, described rotatable pulley 2 is fixedly connected with S. A. 5, and described S. A. 5 is rotatably connected in described mounting seat by bearing 4.

Should be understood that, drive described rotatable pulley 2 to rotate for making S. A. 5 rotation and (be actually the change due to cargo location, hauling rope is caused to drive rotatable pulley 2 to rotate, and the revolving property of S. A. 5, rotatable pulley is made not hinder rotation), as a preferred implementation of the present embodiment, described rotatable pulley 2 is welded with described rotation 5 axle.

Further, for easy for installation, except the mode of welding, the present embodiment as shown in Figure 1, give another kind of fixed form, described rotatable pulley 3 is flexibly connected with described S. A. 5, and is compressed by the axle cap be arranged on S. A. 5, makes described rotatable pulley 3 relative fixing with described S. A. 5.Again during detachable maintaining, take off described axle cap, by the rotatable pulley 3 be connected with S. A. 5, afterwards from the desirable Shaft 5 of the other end of mounting seat 1, carry out changing or keeping in repair.

It should be noted that, above-mentioned S. A. revolves the mode of 5 turns, and friction force is little, and when described S. A. 5 is connected to described mounting seat 1 by bearing, the two ends of described S. A. are all provided with bearing 4, and described S. A. 5 freely can be rotated in mounting seat 1.

As the present embodiment one preferred implementation, the utility model gives the another kind of connection mode of rotatable pulley and S. A., namely S. A. is actually anchor shaft, be fixed in mounting seat, and an outwardly cylindrical structural, upper end is comparatively thick, and middle installation one is relative to the rotating annulus of this cylinder, and annulus is fixedly connected with rotatable pulley.

In above-mentioned embodiment, described annulus to be socketed on described anchor shaft and to rotate around described anchor shaft, the upper end of annulus is divided by anchor shaft thicker part and is blocked, and bottom is blocked by mounting seat, thus annulus only can be rotated on anchor shaft, and can not be up and down, should be understood that, anchor shaft is herein fixed in mounting seat, is not restricted to welding manner, for making follow-up detachable maintaining convenient, the described mode that is fixedly connected with also can connect for bolt, crimping etc. removably connects.

A shown in Fig. 1 is hauling rope horizontal direction angle adjustable, b is hauling rope vertical direction angle adjustable, be appreciated that by the embodiment of the present embodiment, when the perpendicular line of rotatable pulley 3 between two pulleys rotates, rotatable pulley 3 solves the problem of hauling rope horizontal direction angle adjustable, achieve the purpose of this utility model, and rotatable pulley 3 is designed to be in goods sustained height in the horizontal plane as far as possible, thus solves hauling rope vertical direction angle adjustable problem.

Finally it is to be noted: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit.Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
