Abstract

The hoist is characterized in that the combination of the hoist mainly comprises a driving (sliding) wheel (1) which is composed of two parallel semi (sliding) wheels (2 and 3); an elastic means (4) axially pressing the half-wheels (2, 3) together; a cable groove (5) formed by two half-wheels, which groove has at least parallel side parts (12, 13) in the area of clamping the cable (11); and a small guide wheel (6) of the steel cable rotating along the whole contact angle range of the steel cable groove (5).

Description

Hoist crane

The present invention relates to a kind of hoist crane, in other words, relate to a kind of lifting load or utilize the device of the rope traction load of driving wheel guiding.The hoist crane one of this form that The present invention be more particularly directed to active (cunning) wheel is to lump together half (cunning) wheel that can form steel wire rope groove by two to combine.

By can recognize among the european patent application Nr 189,219, already used hoist crane, its two are utilized coarctate half wheel of elastic mechanism, form a V-arrangement steel cable groove.

But the major defect that this cucurbit has is, on the one hand because brute force makes two and half to take turns mutually to pressing, on the other hand because the groove of this vee shape, make steel cable be subjected to the radial outward extruding, therefore cause obstruction and effect of irregular this device normal operation.

Primary and foremost purpose of the present invention provides a kind of hoist crane that is intended to avoid above-mentioned shortcoming.More generally, the intent of the present invention also is to provide a kind of hoist crane, and this cucurbit embodies and combine following favourable characteristics:

-main utilization is in half wheel of parallel position mutually, makes in the whole angle of contact scope on the steel cable pressurized even.

-after the steel wire end is sent into cucurbit, spool into the position automatically easily.

-steel rope remains on two and half the trams between taking turns in whole circumference.In other words, steel cable can radially not shift out from the fleet wheel first heart.

Therefore, form hoist crane of the present invention and be characterised in that: its composition mainly contains a driving wheel, and this driving wheel is taken turns by two and half and formed, and axially takes turns coarctate elastic mechanism with two and half; One is utilized the two and half steel cable grooves of taking turns formation, and this groove has parallel sidepiece and little steel cable guide wheel at least in clamping the zone of steel cable, and this steel cable guide wheel rotates in whole angle of contact scope especially together.

For these features of invention are described better, consult accompanying drawing below, provide explanation to a most preferred embodiment, only make an example but not any determinant attributes, wherein

Fig. 1 represents a transversal surface according to hoist crane of the present invention;

Fig. 2 is illustrated in the transversal surface between two and half (cunnings) wheel;

The enlarged view of the part that indicates with F3 in Fig. 3 presentation graphs 1.

As depicted in figs. 1 and 2, mainly forming by hoist crane of the present invention is a driving wheel 1, and this is taken turns by two and parallel partly take turns 2 and 3 and form; 2 and 3 elastic mechanisms that axially press together 4 will partly be taken turns; One by the two and half steel cable grooves 5 of taking turns to form and many little guide wheels 6 of steel cable of arranging along steel cable groove 5 excircles.

Partly taking turns shown in the present embodiment 2 can be installed with respect to shell 9 rotation by bearing 7 and 8.Second half take turns 3 by a plurality of bolt 10 relative first half take turns 2 fix in position, bolt 10 supports above-mentioned elastic mechanism 4 simultaneously.

Axially will partly take turns 2 and 3 elastic mechanisms that press together 4 can be made up of arbitrarily selected spring, Belleville formula spring for example, coil spring etc.Notice, the tension force of spring is by the power decision that is applied on the steel cable 11, i.e. decision by this way, spring is indeformable on the one hand, will have enough friction force to make the load that is promoted by this cucurbit the danger of any slippage can not occur on the other hand.

A notable attribute of the present invention is, in fact, what provided a kind ofly makes up it two and half to take turns 2 and 3 is parallel, and in the nipped zone of steel cable, have parallel

lateral parts

12 and 13 by partly taking turns the 2 and 3 steel cable grooves 5 that form, more specifically as shown in Figure 3.

This saddle cloth herd the drooping plan of flat stone with ropes attached at the sides Huan fine gold an ancient small-mouthed wine vessel tomb  lead to bite wash bright young  Ji and flatter whole) the angle of contact scope has to join with

parallel side portions

12 and 13 and merges the

angled sides

14 and 15 that forms the vee shape part.

Angled sides

14 and 15 is preferably made with the principal plane of steel cable driving wheel 1 and becomes included angle A, is 12.5 degree.Partly take turns 2 and 3 outermost circumference and can do

fillet

16 and 17.

As shown in Figure 2, the little guide wheel 6 of above-mentioned steel cable mainly is the whole circumference setting along steel cable groove 5.These little guide wheels preferably are made up of the bearing that is installed on the little axle 18, and little axle is fixed in the shell 9.

Use the little guide wheel 6A of steel cable that its diameter is bigger than the diameter of the little guide wheel 6 of other steel cables near being preferably in zone 19, in zone 19, the free end 20 of steel cable 11 is introduced respectively or is drawn.Its advantage back is released and is separated.

Obviously, all little guide wheels 6,6A can have identical diameter.

This cucurbit is driven best by means of axle drive shaft 21 and external tooth 22; The planetary wheel 23 of rotation is set and rises with one around axle drive shaft 21; With a sleeve 24 that is fixed on the driving wheel 1, this sleeve is by its internal tooth 25 and planetary wheel 23 engagements.Axle 21 both can utilize rocking handle or allied equipment to come also can drive automatically with manual drives, and such as driving by an electrical motor, whether this motor is fixed to all is feasible on the above-mentioned casing 9.

Adopt above-mentioned planetary connection, mainly contain the advantage that can make hoist crane compact especially.

Obviously, hoist crane is equiped with the parts 26 or 27 that device can be fixed with effective means.

Can be easy to infer the service condition of this hoist crane with reference to the accompanying drawings.At first, both can also can therefore utilize the little guide wheel 6 of steel cable automatically steel cable to be guided around driving wheel 1 simultaneously through passage 28 through passage 29 with steel cable 11 1 end introducing devices.Thereby as mentioned above because the particular design of steel cable groove 5, act on making a concerted effort on the steel cable, launch by this way, when introducing steel cable 11, two and half take turns 2 and 3 is pushed separately and this steel cable is brought into correct control position.In normal work period, steel cable 11 is in the steel cable groove 5 by this way, and as shown in fig. 1, promptly it is sandwiched in half and takes turns between 2 and 3 the two

parallel side parts

12 and 13.

Be also noted that between the normal used life of this hoist crane the little guide wheel 6 of steel cable does not apply any pressure to steel cable.On the other hand, steel cable be introduced into or the zone 19 of ejector near, the little guide wheel 6A of steel cable applies certain pressure to steel cable 11, so that downwards steel cable is controlled in the steel cable groove 5.By first kind of possibility scheme, the little guide wheel 6A of steel cable can fixedly mount, and by second possibility scheme, can pass through spring or like, pushes away this little guide wheel (not shown) to driving wheel 1 direction.

The present invention is not limit by the foregoing description, and such hoist crane can be realized difformity and size and not exceed protection scope of the present invention.
