Has a load lifting limiter 14 that is installed on the cover body panel 71, its support body 141 is connected on the cover body panel 71, spring 142 Weihe are enclosed within on the montant of support body 141, below, spring 142 bottoms has a travel switch 147 that is installed on the support body 141, be fixed with a left side on the base plate at support body 141 middle parts, right two guide rail brackets 145, the two ends of the center-wheel arbor of a pulley 144 slide over respectively in the vertical guide groove 148 of two guide rail brackets 145, pulley 144 left sides, each storing of the below of right both sides center-wheel arbor has a fork 143, one end of two forks 143 is all lived mutually with support body 141 by hinge pin 146 and is hinged, the other end of two forks 143 all is connected on the connecting rod 149, and the bottom face of connecting rod 149 contacts with spring 142 tops; Have one and be installed in the little gin pole 8 that overlaps body panel 71 forward right side, the following vertical rod 81 of little gin pole 8 is fixed on cover body panel 71 forward right side upper pright stanchions 82, and to slide over down vertical rod 81 interior and free to rotate, be fixed with a cross bar 83 on upper pright stanchion 82 tops, a pulley 84 respectively is equipped with at cross bar 83 two ends, be fixed with a manual winch 85 on the upper pright stanchion 82, be wound with the end on the manual hoist 85 and be fixed on steel rope 86 on this winch 85, steel rope 86 is upwards successively through two pulleys 84, and the next suspension hook 87 that can be used to lift by crane column standard knot 12 that is fixed with in the other end then hangs down; Come the hoist rope 15 on the reel 35 of self-balancing winch 3, upwards walk around the pulley 144 on the load lifting limiter 14, be incorporated between two carrying rollers 94 on the swing arm joint 9 then and pulley 95, walk around the fixed pulley 101 of arm of derrick 10 ends again, be connected mutually with the shoulder pole fine strain of millet 111 of a combination suspension hook 11 at last, shoulder pole girder 111 belows have the several suspension hooks 112 that are connected mutually with it, and the quantity of suspension hook 112 is good with three.
The utility model with said structure is when concrete the use, start the motor 31 of balance winch 3, its hoist rope 15 drives combination suspension hook 11 can lift by crane weights such as building object, the counterbalanced weight 5 that balance rope 16 direct bearings hang, both can reduce the complete machine unbalanced moment, can balance a part of hoisting capacity again, reduce elevator moment, reduce power of motor.When normal crane lifting service, dual gear 34 is meshed with the internally toothed annulus 351 and 371 of reel 35 and 37 respectively, one positive one instead hoist rope 15 and the balance rope 16 on two reels 35 and 37 form equilibrium relations.In case of necessity, can with manually throw off internally toothed annulus 351 with 371 respectively with being connected of dual gear 36, reel 35 and 37 is dallied on drum shaft 34.Combined type hook 11 common object both capable of hoisting is convenient to hang strip-shaped object again, and is easy to use.Because hoist rope 15 is walked around the pulley 144 on the load lifting limiter 14 halfway, therefore the tension force of hoist rope 15 can be oppressed fork 143 to lower swing, make spring 142 pressurizeds, when overweight, can touch the travel switch 147 in motor 31 control circuits that are connected balance winch 3,, control circuit makes motor 31 stalls so that being cut off, thereby limited the tension force maxim, prevented overweight and super moment, thereby prevent the accident of rushing to summit.
Start the handwheel 41 of movable pendulum arm mechanism 4 with palm, by handwheel 41 radiuses the multiple proportions of reel 43 radiuses is amplified the tractive force that increases swing arm steel rope 17 and 18, this tractive force acts on the swing arm rope sheave 96 and 910 on the swing arm joint 9 respectively, driving swing arm joint 9 rotates around its center pin 92, can realize the swing of arm of derrick 10 in 100 ° of scopes of horizontal surface, thereby realize the parallel motion of lifted weight.
Operation on the height that the utility model can be adapted to constantly raise in the building ground.When needs are increased the height of supporting upright post, its column standard knot 12 that constitutes supporting upright post can lift the column end face by using little gin pole 8, connect bolt, the pulley yoke 13 that will climb then places on the additional good column standard knot 12, again the back segment of hoisting cable 15 is separated from combination suspension hook 11, throw off simultaneously with arm of derrick 10 on the contacting of fixed pulley 101 and swing arm joint 9 top sheaves 95 and carrying roller 94, and as shown in Figure 7, direct pulley 144 from load lifting limiter 14 is incorporated into hoisting cable 15 the stock back pulley 73 of lifting stock 7, walk around climb fixed pulley 131 and 135 and stock front wheel 72 on the pulley yoke 13 that climbs again successively, hoist rope 15 tail ends are bound be fixed on the lifting stock 7 at last.After performing above-mentioned dead work, start balance winch 3, power by means of hoisting cable 15, just lifting stock 7 and relevant portion all can be promoted along column standard knot 12, when putting in place, height positioning plate 134 can be actuated the travel switch 74 in the motor that is connected balance winch 3 31 control circuits at cover body panel 71 tops, control circuit being cut off and force balance winch 3 to stop, thereby prevents to rush to summit.Add column standard knot 12 so repeatedly, repeatedly lifting stock 7 is promoted, up to reaching predetermined altitude.Like this, the utility model balance crane has just reached self-chambering from the purpose that rises.
Referring to Fig. 1 and Fig. 3, for convenience and the self-chambering when helping the utility model and beginning most, can also install a pulley 21 at operator's station 2 tops, install a pulley 76 at the top of the cocked hat 75 of lifting stock 7.When beginning self-chambering most, install base 1 earlier, added ballast, the fitting operation platform 2 then, and balance winch 3 installed on the operator's station 2, next lifting stock 7 is enclosed within on the column bottommost one joint column standard knot 12, and these coxopodite 12 lower ends and a pair of bearing pin 19 of base 1 usefulness are connected, be disposed across ground, again as shown in Figure 10, to hoist rope 15 tail ends be bound be positioned at operator's station 2 tops at last from the hoist rope 15 of the reel 35s of balance winch 3 pulley 21 at pile warp operator's station 2 tops successively and the pulley 76 at lifting stock 7 tops.After performing above-mentioned dead work, start balance winch 3,, just coxopodite 12 and lifting stock 7 plates can be risen,, connect another then bearing pin 19 up to becoming vertical state by means of the power of hoisting cable 15.
The utility model simple and compact structure, power are little, in light weight, are convenient to manpower and move and transport; Can be implemented in the building site self-chambering and rise certainly, can vertical-lift, again can be among a small circle parallel motion; Can directly unload and entrucking, reduce many a dead lift work; Strong to the workyard comformability, security consideration is thoughtful, cost is low, price is cheap, does not have much basic requirements, saves erected cost, many small towns Minor Construction team all can be bought, really accomplish simple being suitable for, economical and practical, be the desirable facility that promote the construction of normal domestic vehicle for construction, alleviate physical labor intensity.
