Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only this utility model a part of embodiment, rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of this utility model protection.
Embodiment:One kind as depicted in figs. 1 and 2 realizes that above-mentioned ultra-large type tower crane high-altitude is torn arm equipment open and included:Raising steel Cord 6, lifting mechanism, side arm 2, after-frame 3, locking device 4 and take-up device 5, side arm 2 and after-frame 3 moving along amplitude variation trolley 1 Direction is articulated in its both sides, and positioned at the top of tower arm;Locking device 4 is arranged between side arm 2 and after-frame 3, for locking And adjust the angle between side arm 2 and after-frame 3;Take-up device 5 is arranged on after-frame, for after-frame 3 and tower arm are fixed;Raising 6 pile warp side arm of steel wire rope is connected with the middle position of joint arm to be removed, and has vertical tension in junction;Lifting mechanism Drive hoist rope.Realize tearing movement of the arm equipment in tower arm open using tower crane itself jib lubbing mechanism, compact overall structure, and Improve aerial removal efficiency.Fixed with joint arm to be removed and tower arm using side arm and after-frame respectively, improve the safety of unloading process Coefficient and stability;Along with vertical tension of the hoist rope to joint arm to be removed, reduce joint arm to be removed dismounting and under Let slip the shaking amplitude of journey.
Above-mentioned ultra-large type tower crane high-altitude is torn open in arm equipment, and side arm 2 and after-frame 3 are locked using the structure of double cabinet frame in front and back Device is that spiral locks steel wire rope, and is fixed using spiral locking steel wire rope between double cabinet frame, and rear man-like shelf and tower arm are utilized Adjustable locking steel wire rope is fixed, and while lifting enabling capabilities are improved, improves the reliability of unloading process.
Man-like shelf structure adopts flanged (FLGD) different length standard knot in front and back, is attached with bolt, reduces dismounting dress The difficulty carried with installing/dismounting is put, while can be adjusted according to the length of different type of machines tower arm, tower top can be widely used in In formula and flat-top tower crane, with good versatility;Along with length-adjustable spiral locks steel wire rope and take-up device To realize luffing function, sling crane arm centre position to be torn open with vertical tension with ensureing hoist rope, solve crane arm from Impact of the body tilting moment to lineoutofservice signal pull, it is ensured that in dismounting and lower section process hoist rope tension equalizer, from stress control Whole dismounting process stability is improved in system.
Length of the length of the bar of front man-like shelf more than the bar of rear man-like shelf, before and after raising, double cabinet frame is in use Stability.
Dismounting explanation is carried out as a example by eight joint arms are had in tower arm, there is in the 6th joint arm long draw.
As shown in figure 3, tearing Section eight of arm equipment Removal tower arm using a kind of ultra-large type tower crane high-altitude of the present utility model open Arm, amplitude variation trolley 1 is moved in the 7th joint arm 8, and rear man-like shelf is fixedly connected with the 7th joint arm 8 by adjustable, in tower arm certainly Before 6 pile warp of hoist rope of band, the pulley on man-like shelf top is connected to the middle position of the 8th joint arm 7;It is adjustable by adjusting Locking steel wire rope adjusts the height between after-frame and the 8th joint arm 7, before being adjusted by adjustable screw locking steel wire rope man-like shelf and Angle between man-like shelf afterwards, so as to the hoist rope 6 of pile warp side arm top sheave is vertical with Section of eight tower arm 7 tense;Remove The connection bearing pin on the top boom and lower boom of the 8th joint arm is dismantled, is finally started lifting mechanism and the 8th joint arm is vertically transferred.
Side arm and after-frame are fixed with amplitude variation trolley, realize the movement in tower arm, nothing using tower crane itself jib lubbing mechanism Repeated removal and fixation are needed, while vertical tension lifting tower arm makes the dismounting of lower bearing pin simpler, aerial dismounting effect is improve Rate.When the top-bottom chord of tower arm is dismantled, removed by the pulling force that only slightly need to adjust hoisting easily, save dismounting top boom bearing pin The process that crane arm is rotated around lower boom bearing pin afterwards, dismantles and decentralization process shaking amplitude is little, improves the safety system of unloading process Number and stability.
7th joint arm is identical with the dismounting mode of the 8th joint arm.
The dismounting mode of the 6th joint arm as shown in Figure 4 and Figure 5:Amplitude variation trolley 1 is moved to into the 5th using jib lubbing mechanism In joint arm 10, first the pulley of the tower top of the 6 pile warp tower crane of hoist rope in tower crane is torn open with the long draw 12 in the 6th joint arm 9 Arm-tie connection is unloaded, then long draw 12 is removed with tower cap 14, the dismounting of long draw 12 is completed;According to the 8th joint arm or Section seven 6th joint arm is dismantled by the dismounting mode of arm;Lifting mechanism is utilized finally by the 6th joint arm after the long draw after dismounting and dismounting Together transfer.
5th joint arm affects the balance between counter-jib and tower arm in dismounting;Therefore, when five joint arms is dismantled, need Want the counterweight on corresponding dismounting counter-jib.Counterweight and the 5th joint arm intersect dismounting.The dismounting mode of the 5th joint arm and upper State dismounting mode identical.The dismounting of counterweight is as shown in fig. 6, by the pulley and counterweight to be removed of 6 pile warp tower top of hoist rope Connection, the connector of fixed weight is dismantled, and starts lifting mechanism, and lifting mechanism drives hoist rope by counterweight to be removed Decentralization.
Three joint arms are identical with the dismounting mode of logical 5th joint arm of the dismounting of the 4th joint arm.
The upper only preferred embodiment of the present utility model, it is not to limit this utility model, all in this reality Within new spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in of the present utility model Within protection domain.
