Description
One, technical field：
The present invention provides a kind of shifting balance dynamic equilibrium tower crane again, belongs to building machinery.
Two, background technology：
Tower crane is that modern elevation builds essential common equipment, and 360 degree of reducing lifting and dispensing cover, greatly
The labor intensity for alleviating worker, improve work efficiency, but the tower crane under the prior art, be with safety of tower crane stability series
The fixation negative balance value of arm and counter-jib in number ranges is that hoisting weight absolute value and luffing dynamic relative value are limited work
's.This fixed balance mode not only limits the crane capacity of tower crane and launches coverage area, also tower crane is made to be chronically at
Among the unstable state and structural fatigue of gravity negative balance.
Three, invention content：
The purpose of the present invention is in view of the above problems and insufficient, provide that a kind of elevating capacity is stronger, area coverage bigger, answers
With with the more stable safe shifting balance dynamic equilibrium tower crane of stationary state.
A kind of shifting balance dynamic equilibrium tower crane again comprising tower body, arm, counter-jib, balance weight, amplitude variation trolley, flat
Weight trolley, lift heavy sensor, luffing sensor, luffing capstan winch, crab capstan, balance weight capstan winch and electromagnetic clutch, it is special
Sign is the balance weight trolley that carry balance weight is arranged on counter-jib and the counter-jib boat rail for its movement, in luffing capstan winch and is risen
Coaxial balance weight capstan winch is arranged in weight capstan winch side, and the operating of balance weight capstan winch is by electromagnetic clutch controller control；
The balance weight carry is pulled in back and forth movement and lock on counter-jib boat rail on balance weight trolley by control cord
Positioning is set；
The balance weight capstan winch coaxially respectively set in luffing capstan winch and crab capstan side it is a set of, by electromagnetic clutch control join
It connects, realizes that the linkage of balance weight trolley and position lock by same control cord, balance weight capstan winch and luffing capstan winch and lifting
The Zhou Jing ratios or rotating ratio of capstan winch are with the length of counter-jib than identical；
The electromagnetic clutch receives lift heavy sensor and the control of luffing sensor, within the scope of rating number, connects
Electromagnetic clutch power is operated synchronously in company with luffing capstan winch or crab capstan, and the small truck position of shifting balance weight is detached from rating number
Range cuts off electromagnetic clutch power, electromagnetic clutch separation, the small truck position of locking balance weight.
The crab capstan, it is characterized in that the brake retarding means that weight is liftoff and contacts to earth has been arranged.
Dynamic equilibrium tower crane makes between arm and counter-jib always the shifting balance of the present invention compared with prior art again
In dynamic equilibrium in gravity, crane capacity is stronger in, and dispensing coverage area is wider, application and application intermittent phase tower crane
Entirety is in the relative equilibrium stable state of gravity, influences resilience to external force, such as windage it is stronger, it is more stable, more pacify
Entirely, the service life is longer.
Four, it illustrates：
Fig. 1 is shifting balance dynamic equilibrium tower crane floor map again.
In figure：1 tower body, 2 arms, 3 counter-jibs, 4 balance weights, 5 tower caps, 6 amplitude variation trolleys, 7 balance weight trolleies, 8
Arm boat rail, 9 counter-jibs boat rail, 10 lift heavy sensors, 11 luffing sensors, 12 luffing capstan winches, 13 crab capstans, 14
15 electromagnetic clutch of balance weight capstan winch, 16 control cords, 17 control rooms.
Five, specific implementation mode：
The present invention is illustrated in further detail below with reference to the accompanying drawings of the specification：
As shown in Figure 1, tower crane top is made of tower body 1, arm 2, counter-jib 3, balance weight 4 and 5 main part of tower cap, balancing
Counter-jib boat rail 9 and balance weight trolley 6,4 carry of balance weight are set on balance weight trolley 7, being drawn by control cord 16 can on arm 3
It is moved left and right on counter-jib boat rail 9.Lift heavy sensor 10 and luffing sensor 11 are set on the amplitude variation trolley 6 of arm 2, become
Width trolley 6 is when lifting by crane on arm boat rail 8 and being mobile, by lift heavy sensor 10 and luffing sensor 11 by slinging matter weight and change
Width data transfer enters control room 17, the luffing capstan winch 12 of 5 lower part of tower cap and the setting of 13 side of crab capstan it is coaxial, by electromagnetism from
Clutch 15, controller control balance weight capstan winch 14 realize linkage and the position of control balance weight trolley 7 by same control cord 16
Locking.Weight is set at crab capstan 13 and lifts by crane the brake retarding means that liftoff and dispensing is contacted to earth.
Shifting balance again dynamic equilibrium tower crane is after combine and lay-up period by installation, according to arm 2 and 3 fixed numbers of counter-jib
Adjust 4 position of balance weight, the balanced steady state for keeping arm 2 equal with gravity at 3 both ends of counter-jib.
Dynamic equilibrium tower crane is operating in application, the weight weight according to the input of lift heavy sensor 10 is exhausted shifting balance again
The dynamic lever force that the lever force weight relative value and luffing sensor 11 formed to value and 6 present position of amplitude variation trolley inputs
Weight is started by control room 17 or is closed electromagnetic clutch 15 with respect to Value Data, starts balance weight capstan winch 14 and operates, control movement
7 position of balance weight trolley or locking make arm 2 and counter-jib both ends be in always in static and dynamic balance and operate.
For shifting balance again in dynamic equilibrium tower crane operating application, slinging matter weight is negative beyond specified arm 2 and counter-jib 3
When range of balance, start the liftoff brake retarding means with dispensing landing of lifting, 14 shifting balance of link balance weight capstan winch weight is small
7 shift position of vehicle realizes arm 2 and completes lifting and landing after the new balance in 3 both ends of counter-jib.
It is the known technology of those skilled in the art in addition to the technical characteristic described in specification.
