Description
Technical field
The present invention relates to a kind of large bridge suspension bridge jackstay and put rope construction equipment, specifically a kind of suspension cable
Bridge jackstay puts rope machine.
Background technology
Suspension bridge has another name called suspension bridge, refers to the cable to be hung and to be anchored in two sides (or bridge two ends) by Sarasota as upper
The bridge of the main supporting member of portion's structure.The main supporting member of suspension bridge is suspension cable, and suspension cable is to be combined by a lot of strands,
Each strand is produced by production plant and is wound on Suo Panshang, then transports to building site and releases and set up, is hung by Sarasota and anchor
In two sides, frame rope process is also known as putting rope, and the erection of suspension bridge strand is the important procedure of bridge construction construction, and conventional puts rope side
Formula uses support support cable dish, and the loading of rope dish is first to penetrate in rope dish with an axis, hangs on support the most again, the most not side
Just, and the time is the longest, the free swinging of bearing, need to put rope with a large amount of human assistances, to rear employing reductor drive-type, but does not solves
Certainly during putting rope, rope puts that rope diameter is descending, rope dish rotary inertia, to put rope speed be change, puts during rope not
Can self-adaptative adjustment, thus there will be put motionless, cross put, random dish, the pine phenomenon such as dish, loose wire, strand rope silk is had wound greatly
Evil, this is the subject matter existing for original construction technology and equipment, absent variable in bridge construction process.
Chinese patent CN2740574Y discloses the device that a kind of suspension bridge construction main cable strand is released by rope dish, and machine is stretched on top
Structure is fixed on the centre bore of rope dish by connector, and Ding Shen mechanism connects damping mechanism and torque motor.Damping mechanism
Being made up of arrestment mechanism and gear, gear is to be made up of gear pair and reductor.This suspension bridge construction main rope
The passive rope releasing device of stock, it overcomes " Ho La hoop " shape during tradition suspension bridge construction Strand Erection puts rope to a certain extent
Become phase mutual friction between strand, extruding to produce broken belt, filoselle bad phenomenon, but for the gross weight of volume rope dish reach 40t ~
70t, requires midway to stop during putting rope, adjusts rope or chance fortuitous event to stop in emergency, due to volume rope dish weight ratio more relatively
Greatly, rotary inertia is big, and inertia is big, and damping mechanism and torque motor are not enough to brake rope dish.
Summary of the invention
The present invention provide one can stop off, put rope end or meet fortuitous event need to stop time can use hand-driven belt type
The suspension bridge jackstay that brake auxiliary is steadily stopped puts rope machine.
The present invention is achieved in that
A kind of suspension bridge jackstay puts rope machine, including torque motor 1, hydraulic push-rod brake 2, reduction gearing 3, driving shaft
The bearing support 8 of 4, Fang Shengjige mechanisms, Partner axle stretches 9, and wherein rope dish 7 is placed in driving shaft 4 and Partner axle is stretched on 9, and it is special
Levying and be, described driving shaft 4 also includes one for stopping the brake gear that rope dish 7 rotates.
Brake gear includes a belt brake disc 6 being arranged on driving shaft 4, and belt brake disc 6 is through moment pin 5 even
Connect；Brake ribbon 11 is arranged in the groove 10 of belt brake disc 6, and wherein one end of brake ribbon 11 is fixed on the fixed pin shaft of support
On 15, the other end is connected with lever hinge 12, and the degree of tightness of the lift adjustment brake ribbon by operation screw mandrel 13.
Beneficial effect
1. the present invention is for the big rope machine of putting of tonnage, and the gross weight of rope dish reaches at 40t ~ 70t, and rotary inertia is big, and inertia is big,
Requiring midway to stop during putting rope, adjust rope or chance fortuitous event to stop in emergency, reduction gearing and torque motor are not enough to rope
Dish is braked, and thus can cause damage reduction gearing and motor, in the life-span of few machinery that slows down, can make rope dish after the present invention
Can smoothly brake, alleviate and because stopping in emergency, reduction gearing and motor are caused damage, substantially prolongs mechanical life.
2. the present invention can smoothly brake, and also shortens cable tray simultaneously and changes the time of rope dish.
Accompanying drawing explanation
Fig. 1 represents that suspension bridge jackstay puts rope machine schematic diagram
Fig. 2 represents brake gear schematic diagram
Figure identifies 1 torque motor 2 hydraulic push-rod brake 3 reduction gearing 4 driving shaft 5 moment pin 6 carry
Formula brake disc
7 rope dish 8 bearing support 9 Partner axles stretch 10 groove 11 brake ribbon 12 lever hinges
13 operation screw mandrel 14 operating platform 15 fixed pin shafts.
Detailed description of the invention
It is described further below in conjunction with the accompanying drawings:
1 torque motor in Fig. 1, as driving force and the brake power of putting rope machine；2 is that hydraulic push-rod brake is as stopping
Only brake use；3 reduction gearing, strengthen driving torque；4 is driving shaft, as rope dish and the support of belt brake disc；5 is moment
Pin, as rope dish rotary action；6 is belt brake disc, and the frictional force of friction belt generates braking torque by brake disc；7 is rope
Dish；8 is the frame bearing support as Fang Shengjige mechanism；9 stretch for telescopically adjustable Partner axle, as rope dish support and
Handling adjust to be used；10 is the groove of belt brake disc.
In Fig. 2,11 is brake ribbon, during tensioning, brake disc is produced friction pressure；6 is belt brake disc, and drag friction power is produced
Raw braking moment；12 is lever hinge, and 13 is operation screw mandrel, by the lifting of the screw mandrel degree of tightness to brake ribbon；14 is flat for operation
Platform, 15 is the fixed pin shaft of fixing brake ribbon one end.
The typical operation process of concrete rope machine of putting is as follows:
Put rope machine mounting and adjusting to the OFF state that normally works → by rope dish handling to the operation putting above rope machine → rotate rear end
Dish is adjusted to telescopically adjustable Partner axle and stretches 9, adjustable Partner axle is stretched 9 and is adjusted to the state of returning, make Suo Panyu
Put rope movement between centers and have the gap of about 50mm → put down rope dish, make the core axle hole at rope dish two ends be respectively aligned to put the active of rope machine
Axle and movable axis (fixing axle 4 and Partner axle in Fig. 1 stretch 9) → and load onto moment pin (5 moment pins in Fig. 1), make rope dish
The spoke operation dish against moment pin → rotation rear end regulates telescopically adjustable Partner axle and stretches, and is adjusted by adjustable telescopic shaft
Whole on the pull rope of the rope head-clamp making rope dish be on the state of holding out against → connection rope dish and haulage gear, pull device, make to put rope
Machine be in put rope SBR (this clamping process has only to about 10 minutes, and clamping process in the past has only to 70 minutes) →
Starting haulage gear pulls rope muscle to put rope, and adjustment limiter of moment makes to put rope machine and bestows one, rope dish and rotate to contrary power
Square, keep linear velocity and back tension constant, stably put rope process → stop off, put rope end or meet fortuitous event need stop
Shi Keyong hand-driven belt type brake assists the rope that steadily stops → put to end → repeat and puts the above-mentioned work process of rope machine.
Put rope machine for one and rope 6 cable rollings within 10 hours, can be put, and past tradition is put rope machine and within 10 hours, is only capable of putting rope 3 cable rollings.
As can be seen here, the present invention puts rope machine machine compared with original technology, and its beneficial effect implemented also is highly significant.
