Abstract
The utility model discloses a double balanced upper pulley device, relates to hoisting machinery, and solves the technical problem that the double balanced upper pulley device is needed when a crane hoisting mechanism adopts a double-layer duplex winding reel. A balance pulley is connected with a hoisting frame through a pin shaft (III); the hoisting frame is connected with a pull rod through a pin shaft (I); the pull rod is connected with a balance arm through a pin shaft (II); the balance arm is fixed on a beam through a shaft; the beam is fixed on two brackets. The double balanced upper pulley device is applicable to the crane hoisting mechanism; the balance pulley can be used for balancing and compensating upper and lower steel wire ropes; and the balance arm can be used for balancing and compensating forces on two side pulleys.
Description
Technical field
The utility model relates to elevator machinery, particularly a kind of lifting altitude large, adopt double-deck duplex to be wound around the lifting mechanism top sheave device of reel.
Background technology
When lifting altitude is larger; usually can adopt double-deck duplex to be wound around reel; the double-deck winding is that the ectonexine steel rope is steel cable; the ectonexine cable wire end is fixed on reel by pressing plate; the cover wire rope is than steel wire of internal layer rope three circles that lag behind, and after the steel wire of internal layer rope is wound on reel and forms fixing one by one flute profile, the cover wire rope can rulyly be entangled in the plug helix that the steel wire of internal layer rope forms; two-layer steel rope can cross-coincidence, marshalling.But because the cover wire rope is wrapped in outside the steel wire of internal layer rope, the cooling diameter difference of two-layer steel rope, reel revolves the length difference of the steel rope that while turning around, two-layer steel rope is emitted, so balance pulley between the levels steel rope.And while adopting double crosslinking drum, the elongation difference due to the both sides steel rope after stressed, also need balance pulley or balance arm device, so just need use double balance formula top sheave device.
Summary of the invention
The purpose of this utility model is intended to overcome the shortcoming of prior art, and a kind of double balance formula top sheave device is provided, and when the solution crane hoisting mechanism adopts double-deck duplex to be wound around reel, needs to use the technical matters of double balance formula top sheave device.
The utility model is achieved through the following technical solutions:
A kind of double balance formula top sheave device, it is characterized in that: described double balance formula top sheave device is comprised of beam, pull bar, support, equilibrium arm, suspension bracket, equalizer pulley, I bearing pin, II bearing pin, III bearing pin and axle, equalizer pulley is connected with suspension bracket with the III bearing pin, suspension bracket is connected with pull bar with the I bearing pin, pull bar is connected with equilibrium arm with the II bearing pin, equilibrium arm is fixed on beam by axle, and beam is fixed on two supports.
The quantity of described pulley can be 1 or 2, according to the multiplying power of wirerope-winding, determines.
The utility model is compared with conventional apparatus, has the following advantages and beneficial effect:
Due to equalizer pulley is fixed on equilibrium arm by suspension bracket and pull bar, equilibrium arm is fixed on beam by axle, and equalizer pulley can carry out balance and the compensation between upper and lower layer steel rope like this; Equilibrium arm can carry out balance and compensation by the power on two side rollers, realizes balance and the compensation of the steel rope of both direction simultaneously.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The A-A section-drawing that Fig. 2 is Fig. 1;
The B-B section-drawing that Fig. 3 is Fig. 1.
Below in conjunction with accompanying drawing, by preferred embodiment, the utility model is further described.
The specific embodiment
As shown in Figure 1, 2, 3, a kind of double balance formula top sheave device, by beam 1, pull bar 2, support 3, equilibrium arm 4, suspension bracket 5, equalizer pulley 6, I bearing pin 7, II bearing pin 8, III bearing pin 9 and axle 10, formed, equalizer pulley 6 use III bearing pins 9 are connected with suspension bracket 5, suspension bracket 5 use I bearing pins 7 are connected with pull bar 2, pull bar 2 use II bearing pins 8 are connected with equilibrium arm 4, and equilibrium arm 4 is fixed on beam 1 by axle 10, and beam 1 is fixed on two supports 3.
The quantity of described pulley 6 can be defined as according to the multiplying power of wirerope-winding 1 or 2.
Claims (2)
