Description

A kind of tension balancing device of traction wire rope

Technical field

This utility model relates to a kind of tension balancing device of traction wire rope, is particularly suited for four tension balancing device of traction wire ropes.

Background technology

In multi-rope friction hoist system, all carrying of each steel wire rope has extremely important impact, so tension balance device is most important to the lifting safety of system, economy.At present, the technology of the many employings of elevators field is in fag end and upper beam junction, designs one section of screw rod and puts spring.By the length of adjusting screw rod, the equilibrant changing spring adjusts the stress of every traction steel-cable, and then it is the most consistent to make every effort to the stress between many steel wire ropes.But, the adjustment of its traction steel-cable tension force is entirely and manually realizes by existing elevator hitch, there is bigger error, therefore adjusts poor accuracy.

Utility model content

The purpose of this utility model: in order to solve the problems referred to above, this utility model provides a kind of tension balancing device of traction wire rope.Occur under tension force imbalance during multi rope winding, by the equalization of strain mechanism dynamically change regulation equalization of strain by self real-time followability.

This utility model be the technical scheme is that a kind of tension balancing device of traction wire rope, it is characterised in that it includes traction system, the slide-and-guide wheel being arranged on traction sheave side, is connected to the equalization of strain mechanism that slide-and-guide is taken turns.Described traction system includes traction sheave, car, counterweight, traction steel-cable.

The most described a kind of tension balancing device of traction wire rope, it is characterised in that: described slide-and-guide wheel includes leading block, slide rail, the slide block of slip on described slide rail, the directive wheel being arranged on slide block.

The most described a kind of tension balancing device of traction wire rope, it is characterized in that: described equalization of strain mechanism includes one-level balance rope, one-level balance rope two ends are separately fixed on described slide block and through movable pulley, described movable pulley can slide in slide rail, connect on described movable pulley and have two grades of balance ropes, the fixed pulley that described two grades of balance rope pile warps are fixed on metope.

A kind of traction steel-cable equalization of strain method of the present utility model, comprises the steps:

As a example by A, friction windings of restricting by four, when occurring steel wire rope tension unbalanced state in traction system running, owing to each rope tension is different, so the power being carried on directive wheel is the most inconsistent, causing directive wheel to slide in slide rail, each directive wheel position is different.

B, when directive wheel is static, directive wheel is in poised state, and the pulling force of stress balance in horizontal direction, i.e. traction steel-cable is identical with the pulling force size of one-level balance rope.One-level balance rope is the same rope connecting No. 1, No. 2 directive wheel, uniform tension in order on same rope, so No. 1 steel wire rope and No. 2 steel wire rope tension balances.In like manner, No. 3 steel wire ropes and No. 4 steel wire rope tension balances.Two grades of balance ropes are the same rope connecting two movable pulleys, and uniform tension in order on same rope, so the pulling force suffered by two movable pulleys is identical.Pulling force suffered on movable pulley is respectively making a concerted effort of No. 1, No. 2 steel wire rope and making a concerted effort of No. 3, No. 4 steel wire ropes.To sum up, four steel wire rope tension balances.

The beneficial effects of the utility model are: this utility model simple in construction, easily processing, dependable performance, install and safeguard simple, it is possible to be automatically adjusted each steel wire rope tension and balance.Have the advantage that (1) uses slide-and-guide wheel, and equalization of strain mechanism is connected with slide-and-guide wheel.Equalization of strain mechanism position is fixed on hoistway top, no longer moves along with the motion of car, observes easy to maintenance.(2) equalization of strain mechanism use pulley structure, simple in construction, easy to operate, regulation do not postpone rapidly, effect directly perceived.

Detailed description of the invention

Below in conjunction with the accompanying drawings an example of the present utility model is described further:

Shown in Fig. 1, a kind of tension balancing device of traction wire rope, it is characterised in that it includes the traction system 1 being arranged in hoistway, the slide-and-guide wheel 2 being arranged on traction sheave 1-1 side, the equalization of strain mechanism 3 that is connected on slide-and-guide wheel 2；Described traction system includes traction sheave 1-1, car 1-2, counterweight 1-3, traction steel-cable 1-4.

As shown in Figure 1, described a kind of tension balancing device of traction wire rope, it is characterized in that: described slide-and-guide wheel 2 includes leading block 2-1, slide rail 2-4, the slide block 2-3 of slip on slide rail 2-4, the directive wheel 2-2 being fixed on slide block 2-3, described leading block 2-1 and directive wheel 2-2 is wound with traction steel-cable 1-4.
