Technical field

The present invention relates to the traction technical fields of machine-roomless lift, the especially arc type of 8 to 1 machine-roomless lift of collet formula Wiring tracting structure.

Background technique

Elevator needs stable weight balancing system during operation, and counterweight is the important of elevator equilibrium system One of design link, it is related to the normal, steady of elevator, continuous operation, is the important leverage of lift running safety, the mechanism Major function be relative equilibrium car weight, elevator work in can make the weight difference between carriage and counterweight be maintained at limit it It is interior, guarantee that the traction-driven of elevator is normal, and the baudrier of elevator directly determines elevator traction structure to load-bearing.

With the continuous development of social progress and industry, the elevator in life also gets over the vertical transport demand of cargo Come bigger, therefore prospect is also filled with for the market demand of large-tonnage Cargo Lift.For heavy-duty machine room cargo lift, because Its top layer needs to distribute the load carrier etc. of traction machine, and often machine room is all put into wheel in cage bottom bottom and solves top layer The insufficient problem of height, the elevator of existing machine room are generally to use 2:1,4:1 tracting structure, and small part can use 6:1 traction Structure, the above structure substantially meets the elevator demands of 2 to 9 tons of machine room loadings, but the traction ratio of existing coiling is unable to satisfy 9 tons Above cargo lift demand, but because the headroom height of certain specific buildings is inadequate, and need to load vertical compared with parcel Lifting can only use machine-roomless lift, and machine room cargo lift is according to tonnage difference on the market, to meeting large-tonnage requirement Tracting structure stability there is also huge test, for the safe operation for guaranteeing elevator, be badly in need of to existing tracting structure It improves.

Summary of the invention

It is an object of the present invention in view of the drawbacks of the prior art and insufficient, a kind of stable structure is provided, safety is Number is high, and traction capacity can satisfy by force the bow of 8 to 1 machine-roomless lift of collet formula of 9 tons or more of machine room cargo lift demand Font wiring tracting structure.

Technical scheme is as follows:

The arc type wiring tracting structure of 8 to 1 machine-roomless lift of collet formula, including carriage and setting are in car top Rope hitch plate component with the counterweight of carriage side is set, be equipped with traction sheave, cage side directive wheel above the carriage Group, counterweight-side guide wheel group, be equipped with that cooperation counterweight uses below the described counterweight-side guide wheel group to roller group, it is described Cage bottom be equipped with car floor wheel group, the traction sheave, cage side guide wheel group, counterweight-side guide wheel group, to roller group, sedan-chair Return pulley group is detoured using wirerope and is connected, and the wirerope rear and front end is separately fixed on rope hitch plate component, the sedan-chair Return pulley group has the car floor wheel of four groups of car floors that are parallel to each other and are placed horizontally in, and there are four longitudinal for the cage side guide wheel group tool The carriage side guide wheel of placement, the wirerope successively laterally bypass the first sedan-chair downwards around first group of car floor wheel, upward longitudinal direction Compartment side guide wheel, downwards laterally around second group of car floor wheel, downwards it is longitudinal around the second carriage side guide wheel, longitudinal forward bypass third Carriage side guide wheel, downwards laterally around third group car floor wheel, it is longitudinal around the 4th carriage side guide wheel, downwards laterally around the upwards Four groups of car floor wheels form " bow " winding structure.

Preferably, there are three counterweight-side guiding longitudinally disposed and on the same line for counterweight-side guide wheel group tool Wheel, it is described to roller group tool there are four it is longitudinally disposed and on the same line to roller, the wirerope successively intersects 8:1 tracting structure is formed down around to roller and up around counterweight-side directive wheel.

Preferably, the rope hitch plate component include the first rope hitch plate and the second rope hitch plate, first rope hitch plate and Wirerope one end connection of first group of car floor wheel upstream end, the wirerope of second rope hitch plate and first pair of roller upstream end Other end connection.

Preferably, four in roller group are evenly spaced in above counterweight roller as equidistant, right Three counterweight side guide wheels in heavy side guide wheel group are by being equidistantly evenly spaced in the adjacent top between roller.

Preferably, the first group of car floor wheel, second group of car floor wheel, third group car floor wheel, the 4th group of the car floor wheel group Using carriage, all around middle line is benchmark symmetry arrangement to car floor wheel, and four in roller group are to roller with counterweight All around middle line is benchmark symmetry arrangement.

Preferably, first group of car floor wheel, second group of car floor wheel, third group car floor wheel, the 4th group of car floor wheel difference It is made of the car floor wheel of two left and right settings on the same line.

Preferably, the traction sheave is placed between the outgoing line side of roller group and the outgoing line side of the 4th carriage side guide wheel, And it is higher than cage side guide wheel group and counterweight-side guide wheel group.

The invention has the benefit that the arc type wiring tracting structure of 8 to 1 machine-roomless lift of collet formula is by by carriage The car floor wheel group of lower section is arranged to " to bend " type winding structure, cooperation counterweight-side guide wheel group and 8 to 1 traction to roller group around Cable architecture, so as to meet to 9 tons or more machine room cargo lift traction demands, so that carriage remains under heavy-duty In superior equilibrium state, the traveling comfort of carriage is helped to improve, and the application of " bow " type structure is by the sedan-chair of adjacent sets The stress of return pulley group is mutually shared, and is reduced shake of carriage during passing in and out people and goods before and after cabinet, is promoted the use of user Experience, stable structure, safety coefficient are high, have outstanding balance quality and traction capacity, are conducive to generate considerable economic valence Value.
