Description
Technical field
The present invention relates to mechanically operated from tensioning drag device, relate generally to realize externally exporting
Large traction or push-pull effort from tensioning drag device, it can apply to numerous traction drive
Occasion, such as VTOL class (such as hoisting machinery, hoistable platform, elevator etc.), and
Horizontally tracting class (capstan winch of such as heavy vehicle), the field that quite a few hydraulic cylinder is used
Close, hydraulic cylinder can be replaced to use with rational form.
Background technology
For realizing either vertically or horizontally traction function, the technology of comparative maturity is had now to solve
Scheme, the way of realization of non-mechanical is the whole hydraulic system of hydraulic cylinder and auxiliary.And machine
The driving structure of tool formula vertical-lift class mainly divides two big classes: one is to force to promote, and mainly has volume
Cylinder steel wire rope form, i.e. hoist engine, it is used in mining machinery, hoisting machinery, crane etc. more.
Another is sprocket chain strips etc., is used on bottle gouard moved by hands and electric block more.
It addition, by using traction technology to realize the lifting of load, this technology overwhelming majority uses
In elevator occasion, huge due to elevator storage, it is even more important so this technology seems,
Traction technology have employed following device:
1. differential roller
Differential roller is made up of the reel that two diameters are different, and the difference of reel linear velocity forms difference
Dynamic, and drive weight slowly to promote by steel wire rope, the most smoothly high speed rotary motion is turned
Turn to low-speed rectilinear movement.It can displacement enlargement to meet the needs of precision instrument, or almost
Can arbitrarily change to meet peculair motion equation.
The differential reel mechanism of standard is by two cylinder (D1And D2), hawser or chain composition.This
The two ends of bar hawser or chain are fixed, and around cylinder wound clockwise, simultaneously around separately
One cylinder wrapped anti-clockwise.The sheave of hawser bearing load, and when drum shaft turns clockwise
Time from D1, the hawser above loosened will twine D2On, this will make sheave raise a segment distance:
Cylinder in the counterclockwise direction by a uneven torque,
2. traction machine
Traction machine in traction elevator, is the power of tractive driving.Traction steel-cable is by draging
Running wheel one end connects car, and one end connects counterweight.Car makes to drag with the gravity of counterweight
Draw in steel wire rope is pressed on traction race and produce frictional force.So, motor rotation drives traction
Wheel rotates, and drives steel wire rope, drags car and counterweight performs relative motion.I.e. car rises, right
Heavily decline；Counterweight rises, cage descending.Then, car is upper and lower past along guide rail in hoistway
Multiple operation, elevator performs vertically to transport task.
Car and to perform relative motion Beijing South Maxpower Technology Co. Ltd be that the frictional force by between hoist ropes and traction sheave realizes
's.This power is just traction or driving force.The load of lift car and the position of car in operation
Put and traffic direction is all in change.For making elevator have enough tractions in all cases,
Standard GB/T 7588-1995 " elevator manufacture and installation safety standard " regulation:
Traction condition must is fulfilled for: T1/T2·C1·C2≤efα
In formula: T1/T2The bigger quiet pulling force of hoist ropes and less quiet pulling force for traction sheave both sides
Ratio.
C1The coefficient relevant with acceleration, deceleration and elevator special mounting situation, typically
It is referred to as the coefficient of impact
C2Coefficient is affected (to semicircle or cut due to what abrasion caused that traction sheave channel section changes
Mouth groove: C2=1, to V-groove: C2=1.2).
efαIn, f is hoist ropes equlvalent coefficient of friction in traction groove, and α is that hoist ropes is draging
Cornerite on guide wheel.efαIt is referred to as drag coefficient.Which define T1/T2Ratio, efαIt is the biggest,
Then indicate T1/T2Permissible value and T1-T2Permissible value is the biggest, also indicates that lift towing power is the biggest.
3. wire rope gearing
By the roller of two troughs of belt being arranged side by side, connect by certain winding with steel wire rope, principle
Sketch is as shown in Figure 1.Respectively illustrate the volume including including that there is different-diameter respectively in FIG
The differential carrying means of be arranged side by side two reels of cylinder part and include that there is same diameter
The indifferential carrying means of two reels.
Application and the concrete principle details of carrying means are referred to:
Number of patent application: 201310098310.7 " jacking systems based on stepless rope and having
The elevator of this jacking system and hoist engine "
Number of patent application: 201320540619.2 " hoisting apparatus and include this hoisting apparatus
Chain block "
Number of patent application: 201120501178.6 " stepless rope driving devices and use this stepless
