Description
The present invention relates to a kind of automatic balancing method for tension of steel wire and suspension gear, be particularly useful for the mine multi-rope friction hoisting, be applicable to that also other need promote the occasion of transportation.
Multi-rope friction hoisting is the lifting means that big-and-middle-sized mine is used more, it is big that it has hoisting capacity, safety performance is good, advantage rational in infrastructure, therefore enjoy the favor of bargh, but the steel wire rope tension equilibrium problem is an a great problem in the friction drive hoist that uses at present, each steel wire rope tension overbalance is the one of the main reasons of disconnected rope, adopted multiple trial at this problem, as lever, spring loaded, the hydraulic pressure spacer-type, hydraulic screw formula and pulley etc., these devices are exchanged the leveling weighing apparatus also all certain effect, but the load-carrying construction element is more, complex structure, and can not solve the problem of dynamicunbalance.Patent ZL93237844.7 discloses a kind of sealing fluid pressure type permeator that utilizes airtight capsule structure to replace dynamic seal to form, solved the on-the-spot problem of dynamicunbalance for many years, but because the resistance of capsule and casing wall is bigger, under the bigger situation of stroke, can influence the precision of steel wire rope tension balance, its load-carrying construction complexity in addition, path increment is subjected to certain limitation.
In view of the problem that prior art exists, it is little to the purpose of this invention is to provide a kind of resistance, and kinetic balance is fast, simple in structure, steel wire rope tension dynamic balance method and suspension gear that path increment is big.
Steel wire rope tension equilibratory suspension of the present invention, it comprises oil cylinder, side plate, connecting pin, communicating pipe and the four corner connection plates that are connected, the one middle plate that has a gap is set at the middle part of side plate, in the gap of plate, cylinder tube is fixed on the biside plate during hydraulic ram is arranged on pressing plate, middle plate is connected on the wedge rope_ring, side plate is connected on the cross commutation shaft clevis, has three grooves on the piston of oil cylinder, is provided with y in three grooves
xSeal ring and cooperation composite material compensation cover.
The automatic balancing method for tension of suspension gear of the present invention is: the mode that adopts the drawing and pulling type snap ring structure of a plurality of suspension gears and permeator oil cylinder formation, lifting weight passes to cylinder tube by side plate, form in-oil cylinder oil liquid pressure with plunger, wedge rope_ring directly is connected with middle plate, middle plate is with the tension force upward movement of steel rope, the plunger compression cylinder of middle plate pulling oil cylinder, by communicating pipe and shutoff valve automatically regulating each in-oil cylinder oil pressure identical, on the connecting pipeline of each oil cylinder, adopted sensor and signal transition projector.Oil cylinder adopts upper and lower cavity all can advance the double-acting type oil cylinder of oil extraction, and the composite material that is provided with on the piston of oil cylinder compensation cover is transition fit.
Automatic balancing method for tension of steel wire of the present invention and suspension gear, be best suited for the mine multi-rope friction hoisting, adopt the method for clasp drawing and pulling type, join and middle plate bonded assembly device, can realize the dynamic and static balance of steel wire rope tension accurately, reduce liner wearing and tearing and rope-broken accident, prolong steel rope service life; Can adjust the vessel level position at any time and need not cut rope; Can measure lifting capacity exactly also can be to promoting the control of carrying capacity, and its method is reasonable, and is simple in structure, and in-oil cylinder resistance is less, kinetic balance is fast, and under original design height unmodified situation, the adjustment travel amount can increase to 600～800mm, through type approval test, effect is remarkable, has practicality widely.
