Use principle:
1. wedge rope_ring (Fig. 2, Fig. 3, Fig. 4):
Steel rope penetrates around becket bridle 1-14 bending, stressed, drive on the becket bridle 1-14 and move, move until steel rope on interlock lock bolt 1-4,1-10, sleeve nut 1-3 are common and be locked, this moment, the turnbarrel nut made it press bearing 1-15, give initial pressure of preloading spring, make sleeve nut 1-3 and lock bolt 1-4,1-10 screw the back and be difficult for from pine.Pin fag end after with rope clamp 1-1 this moment, and wedge rope_ring just can normally promote use.If change steel rope or scurry when rope more, need only be placed on the baffle plate 1-2 with a backing plate, turnbarrel nut 1-3 contacts stressed and nut and lock bolt screw motion by the sleeve nut with backing plate then, becket bridle is moved down, can from becket bridle, withdraw from until steel rope.
2. screw hydraulic rope regulator (Fig. 5, Fig. 6, Fig. 7):
Clamp 2-1 is used for the guiding of connecting plate assembly in the screw hydraulic rope regulator.Circular nut 2-2 effect has two: one is adjusted the stroke of oil cylinder, and it two is used for just in case oil cylinder when occurring leaking, and with circular nut 2-2 locking suspension rod 2-5, system can continue to use.Cylinder seat 2-3, cylinder body 2-4, cylinder cap structure 2-8, thru-bolt 2-10, nut 2-11 form housing structure, are used for replenishing hydraulic oil and transferring power.Suspension rod 2-5 is used to connect wedge rope_ring and cylinder body, bears lifting load.Special nut 2-6 is used for the fixing of piston structure 2-7, bears the hydraulic coupling that piston transmits.Piston structure 2-7 is used for the usefulness of guiding and sealing.Pressing plate 2-9, pressing plate 2-14 are used for auxiliary fixing.Protecting sleeve 2-12 is used for the protection of suspension rod 2-5, makes to avoid in the suspension rod motion process damaging.Disk 2-13 is used for fixing protecting sleeve 2-12 and protection cylinder body.Plug screw 2-15 is used for the protection of hydraulic fluid port, avoids extraneous dirty thing and enters in the cylinder.Combination seal 2-16 is used for the sealing function of cylinder cap structure and piston structure, prevents that pressure oil from leaking from piston and cylinder cap.Motion to suspension rod and piston simultaneously plays directional tagging.
Principle of work is as follows:
Principle of work (as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7): hydraulic oil enters in the cylinder body 2-4 of four or six screw hydraulic rope regulators 2 by connecting line 3, make piston 2-7, suspension rod 2-5 and cylinder body 2-4 do relative motion, cause wedge rope_ring 2 to fluctuate, thereby the automatic compensation steel wire rope tension makes all steel rope stress balances of elevator system reach very desirable running state.
When 1) transferring rope: when lifting container is out of service, hold lifting container with foreign object, hoisting rope is not stressed, each hoisting cable length of coarse adjustment makes it equal substantially; Wedge rope_ring 1 is installed then, the locking hoisting rope, oil pump begins oiling, and by connecting line 3, pressure oil enters four (or six) screw hydraulic rope regulators, hydraulic oil enters cylinder body 2-4 by cylinder cap 2-8 oilhole, promote piston 2-7, suspension rod 2-5 motion, compression circular nut 2-2 leaves cylinder seat 2-3, an about half stop control lever to oil cylinder stroke, close connecting line main valve 3-1, transfer the knot bundle.
2) normal operation: suspension rod 2-5, piston 2-7 are relative, and cylinder body 2-4 ceaselessly does relative motion, because these four (or six) steel ropes are because of factors such as installation error, manufacturing, loads, cause its tension force difference, steel rope occurs when different in size in the operation process, high hydraulic pressure moment compensates by connecting line in the lower cylinder body of other hydraulic pressure in certain screw hydraulic rope regulator cylinder body, make the interior hydraulic pressure of each cylinder body equate that a whole set of suspension gear keeps dynamical equilibrium always.
3) emergency:, should close immediately to divide the cylinder valve door in the connecting line and screw on circular nut and also carry on the back tight if a cylinder leaks suddenly.Effect is hung with the A type.
Screw hydraulic rope regulator 2 be different from the obvious characteristic of A type suspension gear be exactly in the normal operation process circular nut 2-2 and cylinder seat 2-3 break away from always.In case circular nut 2-2 contacts with cylinder seat 2-3, illustrate and this is transferred again and has restricted.
3. high pressure prevents pounding connecting line (Fig. 8):
Total valve switch 3-1 is used to control oil pump oil liquid in-out cylinder pressure, compression indicator 3-2 is in order to constant voltage data in the display system, and communicating pipe 3-3 is the basic framework of connecting line, and it is made of withstand voltage solid drawn pipe, high-pressure rubber pipe 3-4 is used for being connected of communicating pipe and each hydraulic actuating cylinder, is convenient to a little less than the rigidity adjust.Protection spring 3-5 is used to protect high-pressure rubber pipe to avoid foreign object impact, and sub valve 3-6 is used for closing under the emergency hydraulic actuating cylinder oil circuit, anti-locking system release.Pipe terminal 3-7 is used for being connected between hydraulic actuating cylinder and the cylinder cap, connects, closes fast, safety, convenience.
