Abstract
The utility model provides a monospar electric block's pulley gear, include the wheel carrier, rotate set up in the marginal part has the pulley of grooving above the wheel carrier, and still include and prevent the mechanism that skips rope, prevent skipping rope the mechanism including being fixed in on the wheel carrier and lie in baffle frame, two tip of pulley one side are fixed in thereby last rope blocking rod, two difference of baffle frame can be rotated the prevent wire rope of setting on corresponding rope blocking rod and followed the fender becket bridle of jumping out of in the grooving, the fender becket bridle faces toward the grooving. Even under experience extreme condition, when wire rope will deviate from the rope race, keep off the becket bridle and prevent wire rope to deviate from, avoid the danger of card rope to improve the electric block safety in utilization, and simple structure, compactness.
Description
Technical field
This utility model belongs to crane field, is specifically related to one
The pulley gear of single-beam electric block
。
Background technology
Conventional single-beam electric block pulley gear is not provided with rope skipping prevention device, there is the danger of card rope in extreme circumstances.
Utility model content
This utility model technical issues that need to address are to provide the pulley gear of a kind of single-beam electric block.
For solving the problems referred to above, the technical scheme of this offer is: the pulley gear of a kind of single-beam electric block, it is arranged at described wheel carrier upper edge including wheel carrier, rotation there is the pulley of grooving, also include rope skipping preventing mechanism, described rope skipping preventing mechanism includes being fixed on described wheel carrier and be positioned at the baffle plate frame of described pulley side, two one end are fixed on described baffle plate frame gear rope bar, two be able to rotate rope blocking ring that is that be arranged on corresponding gear rope bar thus that stop steel wire rope to be jumped out from described grooving, described rope blocking ring faces toward described grooving.
In some embodiments, the rotary centerline of described rope blocking ring, described pulley rotary centerline parallel.
In some embodiments, the rotary centerline of described rope blocking ring, described pulley rotary centerline in same level.
In some embodiments, being connected to form a rigidity entirety by gear rope connecting rod between the other end of two described gear rope bars, described gear rope connecting rod is positioned at the opposite side of described pulley.
In some further embodiment, described rigidity entirety is U-shaped.
The utility model has the advantages that: even if meeting with under extreme case, when steel wire rope will deviate from rope race, rope blocking ring stops steel wire rope abjection, it is to avoid the danger of card rope, thus improves electric block safety in utilization, and simple in construction, compact.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings and embodiment is to being originally further described
Fig. 1 is the schematic diagram (lacking stop piece) of the pulley gear of single-beam electric block；
Fig. 2 is the A-A direction sectional view of accompanying drawing 1；
Wherein: 1, wheel carrier；2, pulley；21, grooving；3, baffle plate frame；41, gear rope bar；42, gear rope connecting rod；5, rope blocking ring.
Detailed description of the invention
As shown in drawings, the pulley gear of a kind of single-beam electric block, it is arranged at described wheel carrier 1 upper edge including wheel carrier 1, rotation there is the pulley 2 of grooving 21, steel wire rope, the most again up around pulley 2, is embedded in grooving 21.
Also include rope skipping preventing mechanism, described rope skipping preventing mechanism includes being fixed on described wheel carrier 1 and be positioned at gear 41, two, the bar of rope that 3, two one end of baffle plate frame of described pulley 2 side are fixed on described baffle plate frame 3 and is able to rotate rope blocking ring 5 that is that be arranged on corresponding gear rope bar 41 thus that stop steel wire rope to be jumped out from described grooving 21, and described rope blocking ring 5 is facing to described grooving 21.In the present embodiment, rope blocking ring 5 is set on described gear rope bar 41.Under extreme case, when steel wire rope will deviate from rope race, rope blocking ring stops steel wire rope abjection, owing to can relative slide between rope blocking ring with gear rope bar, therefore can reduce the frictional force between rope blocking ring and steel wire rope, protect steel wire rope, reduce abrasion.
In the present embodiment, in order to strengthen rigidity and stability, being connected to form a U-shaped rigidity by gear rope connecting rod 42 overall between the other end of two described gear rope bars 41, described gear rope connecting rod 42 is positioned at the opposite side of described pulley 2.In the present embodiment, two described gear rope bars 41 are formed by a rod member bending with gear rope connecting rod 42.This plastic simplicity, makes simple, in actual production, however it is not limited to this moulding.
The rotary centerline of described rope blocking ring 5, described pulley 2 rotary centerline parallel.The rotary centerline of described rope blocking ring 5, described pulley 2 rotary centerline in same level.Thus steel wire rope is stably limited in grooving 21.
Examples detailed above is only that explanation technology originally is conceived and feature, and its object is to allow person skilled in the art is to will appreciate that this content and implement according to this, can not limit protection domain originally with this.All equivalent transformations done according to this spirit or modification, all should contain within this protection domain.
