Description

A kind of arm tower crane variable-amplitude steel wire rope is anti-to kink device
Technical field
The utility model is related to the auxiliary equipment field of crane, and in particular to a kind of arm tower crane luffing steel wire Rope is anti-to kink device.
Background technology
Large-scale arm tower crane arm is designed with " bar " structure, steady relative to flat arm derrick crane " beam " structure More preferably, it is less that boom structure accounts for complete machine structure proportion to qualitative energy, and the biggest lifting capacity is then bigger.Arm tower crane luffing machine Structure is required to meet material handling operating position, makes full use of the crane capacity of itself(Amplitude is reduced and can improve lifting Amount), the operating mechanism of change amplitude is realized, and for expanding the working range of derrick crane, improve productivity ratio.Jib lubbing mechanism Typically it is made up of rack winch, steel wire rope, assembly pulley etc..Due to existing in arm tower crane variable-amplitude steel wire rope steel wire rope Itself very big torsion, easily kinks after coming into operation.Variable-amplitude steel wire rope affects normally using for tower crane, lift arm after kinking Bar can cause variable-amplitude steel wire rope heavy wear, there are major safety risks.
At present for the solution that variable-amplitude steel wire rope is kinked is to carry out putting the process that disappears, i.e., reversed according to luffing assembly pulley The number of turns determining the number of turns of wirerope-winding, extract out, carries out turn-back by the fixing end by variable-amplitude steel wire rope from hoist engine, and Steel wire rope after torsion is reattached on elevator machine cylinder.This mode needs for the strength of torsion to arrive in luffing assembly pulley On, carry out rising and falling armed lever 2-3 time;Single reverses the number of turns no more than 5 circles, and the strength that otherwise steel wire rope is kinked is excessive, it is easy to will Steel wire rope is damaged(Snuff), that is, can not disposably complete by the above-mentioned broken method that disappears, needs repeatedly just can take effect.So this Kind puts the mode of disappearing needs a large amount of labours and working time, and once breaking the work that disappears needs 15 people to be completed with 3 day time, working strength Height, it is dangerous very big, and this problem cannot be effected a radical cure, again the phenomenon for kinking occurs within 1 year or so.
The content of the invention
In order to solve the above problems, the utility model provides a kind of arm tower crane variable-amplitude steel wire rope to be prevented kinking dress Put, its simple structure, easy to use, low cost effectively prevent variable-amplitude steel wire rope from kinking, it is not necessary to which artificial breaking disappears and tie up Repair, save substantial amounts of maintenance cost and time, and ensure that plant equipment uses safety and construction safety.
The technical solution adopted in the utility model is as follows:
A kind of arm tower crane variable-amplitude steel wire rope is anti-to kink device, including horizontal crossbeam and is vertically arranged in two The supporting leg at crossbeam two ends, upper end and beam welding, the lower end of the supporting leg are provided with the connecting portion for installing fixed whole device, The connecting portion include upper connecting portion and with this on the lower connecting portion that coordinates of connecting portion, the welding of the upper connecting portion and supporting leg is solid It is fixed, the lower connecting portion and upper coupling part from or be bolted.
Above-mentioned arm tower crane variable-amplitude steel wire rope is anti-to kink device, and the upper and lower connecting portion is horizontal cross and sets The steel plate put, its length is 500-600mm, width is 100-160mm, thickness is 16-20mm;A left side for the upper and lower connecting portion Right two ends offer respectively bolt hole, a diameter of 16-22mm of the bolt hole.
Above-mentioned arm tower crane variable-amplitude steel wire rope is anti-to kink device, and the supporting leg is steel pipe, its a diameter of 80- 100mm, thickness are 5mm, length is 800-1000mm.
Above-mentioned arm tower crane variable-amplitude steel wire rope is anti-to kink device, and all weld seams are surrounding full weld and face of weld Scribble antifouling paint.
Above-mentioned arm tower crane variable-amplitude steel wire rope is anti-to kink device, and the crossbeam is the channel-section steel that Open Side Down is arranged, Its specification selects 32# or 36#.
The beneficial effects of the utility model are:
1st, this device is " door " font structure, and simple structure, low cost, use are safe;Using the utility model, two are made Assembly pulley is mutually constrained, and prevents from because of steel wire rope torsion reversing luffing assembly pulley, so as to avoid steel wire rope from kinking.
When the 2nd, using, this device is vertically connected with portion can be connected by bolt with luffing running block, ease of assembly or dismounting, Save the duration and be conducive to recycling.
3rd, this device will not change the Impact direction of running block and variable-amplitude steel wire rope, and the size of each part changes through enforcement It is good, more stable, long service life during heavy and high lift, and from section bars such as channel-section steel, steel pipes, in the premise for ensureing intensity Under, mitigate deadweight.
