Background technology
Tower crane is a requisite weight-hauling equipment in the modern architecture.For realizing tower machine heavy-duty low-speed, the high-revolving functional requirement of underloading generally all requires to have the magnification transformable function.Medium-and-large-sized both at home and abroad luffing jib tower machine is narrow and small because of the board position, the reel of lifting mechanism is size-constrained, it is limited to hold the rope amount, the general 1/2 magnification transformable suspension hook that adopts, but because of the strange/mutation that relates to multiplying power changes, general employing both at home and abroad is when magnification transformable at present, and raising line is worn the method around suspension hook again.This method requires more than operating personal two people, and labour intensity is big, and length expends time in.
The utility model content
The utility model provides a kind of swing arm tower machine S. A. odd even magnification transformable suspension hook, and the magnification transformable that solve traditional luffing jib tower machine needs artificial secondary wire rope handling operation, the technical matters that operating efficiency is low.
The technical scheme that its technical matters that solves the utility model adopts is:
This swing arm tower machine S. A. odd even magnification transformable suspension hook, the upper end of steel rope is connected in hoisting crane swing arm frame end portion, pulley is walked around in the lower end, be connected with cover of wedge, pulley is connected between two outer panels by sheave shaft, the bottom connecting shackle crossbeam of two outer panels, suspension hook and lifting beam with hook are hinged, it is characterized in that:
Two outer panels are installed with damper shaft in the front side, and two outer panels are wide at the top and narrow at the bottom, and its shape is inverted pyriform, between two outer panels at pulley both sides parallel connection pair of inside plate.
Interior plate is narrower than outer panel, and its center is hinged on the sheave shaft, and two flanges are arranged respectively on two interior plates, wherein connects the retaining rope sheave between two flanges of rear side; The rear portion of two flanges in front side has the anti-rotation pin-and-hole, all there is draw-in groove in the front of two flanges in two interior plate front sides, this draw-in groove is coincide corresponding with the damper shaft on two outer panels when suspension hook list multiplying power state, and the top of two flanges in front side is all fluted, and this groove is corresponding with the clamp axle to coincide; Connecting panel and cover of wedge are hinged by the clamp axle jointly, the pin-and-hole of the connecting panel other end is when suspension hook two multiplying power states, hinged by adapter shaft and arm end arm-tie, steel rope is connected with the arm end, when single multiplying power state, the pin-and-hole of connecting panel upper end is by anti-rotating pin and anti-rotation pin-and-hole pin joint, prevents that the clamp axle from deviating from from the interior plate groove.
Above-mentioned arm end arm-tie can be the chain type multi-section structure.
Above-mentioned two outer panels are inverted pyriform.
Above-mentioned two interior plates are the shape of a saddle.
The beneficial effects of the utility model are as follows:
The utility model can be more convenient ground realize the conversion of suspension hook list multiplying power and 2 multiplying powers fast, that avoids that the secondary wire rope handling brings is consuming time and inconvenient.When the operation of odd even magnification transformable, only finish by the plug of 2 bearing pins, need not to place ground to carry out the wire rope handling second time on suspension hook, only need 1 operating personal to finish at the arm end.The utility model is convenient and swift than conventional art, helps alleviating labor intensity of operating personnel, and raising work is imitated.

The specific embodiment
Embodiment is referring to shown in Fig. 1-3, this swing arm tower machine S. A. odd even magnification transformable suspension hook, the upper end of steel rope 14 is connected in hoisting crane swing arm frame end portion, pulley 12 is walked around in the lower end, be connected with cover of wedge 6, pulley 12 is connected between two outer panels 9 by sheave shaft 13, and two outer panels 9 are inverted pyriform, the bottom connecting shackle crossbeam 11 of two outer panels, suspension hook gib head 10 is hinged with lifting beam with hook 11.Two outer panels are installed with damper shaft 8 in the front side; Connect pair of inside plate 7 in pulley 12 both sides between two outer panels 9, interior plate is narrower than outer panel, and its center is hinged on the sheave shaft 13, and two flanges are arranged respectively on two interior plates 7, wherein connects retaining rope sheave 15 between two flanges of rear side; The rear portion of two flanges in front side has anti-rotation pin-and-hole 5, all there is draw-in groove 16 in the front of two flanges in front side, this draw-in groove 16 is corresponding identical with the damper shaft 8 on two outer panels when suspension hook list multiplying power state, and the top of two flanges in front side is all fluted, this groove and clamp axle 4 corresponding coincideing; Connecting panel 3 is hinged by clamp axle 4 jointly with cover of wedge 6, the pin-and-hole of connecting panel 3 other ends is when suspension hook two multiplying power states, hinged by adapter shaft 2 and arm end arm-tie 1, steel rope is connected with the arm end, when single multiplying power state, the pin-and-hole of connecting panel 3 upper ends is by anti-rotating pin and anti-rotation pin-and-hole 5 pin joints, prevents that clamp axle 4 from deviating from from interior plate 9 grooves.Arm end arm-tie 1 can be the chain type multi-section structure, also can be other structure.
Working process of the present utility model:
When single multiplying power is changed 2 multiplying powers, the operation lifting mechanism is promoted near the position jib end with suspension hook, connecting panel 3 pin-and-holes of suspension hook just can enter the coverage of arm end arm-tie 1, operating personal stands on the platform of jib end, extract anti-rotating pin 5, adapter shaft 2 is penetrated in the pin shaft hole of connecting panel and jib end arm-tie 1, make hoist rope 14 ends be fixed on the arm end.Operate lifting mechanism then suspension hook is descended, when suspension hook descended, under the self gravitation effect, interior plate 7, outer panel 9 be the different deflection of sheave shaft 13 generations relatively all, enters 2 multiplying power mode of operations; On the contrary, when 2 multiplying powers are changed single multiplying power, the operation lifting mechanism is promoted to the jib end when the certain position with suspension hook, and the interior plate 7 of suspension hook is outer panel 9 rotations relatively automatically under the tension of steel rope 14, be stuck on the damper shaft 8 of outer panel 9 until the draw-in groove of interior plate 7 till.At this moment, retaining rope sheave 15 on the interior plate 7 blocks steel rope 14, changed its direction of drawing from pulley 12, make suspension hook can deflection not too many, the weight of last suspension hook be all transferred on the steel rope 14 of retaining rope sheave 15 1 sides, and arm end arm-tie 1 side is no longer stressed, can extract the connecting panel 3 and the adapter shaft 2 of arm end arm-tie 1 this moment, make the dockingundocking of suspension hook and arm end, then connecting panel 3 usefulness anti-rotating pins 5 are fixed with the suspension hook side plate, the operation lifting mechanism descends suspension hook and promptly enters single multiplying power mode of operation.
