The specific embodiment
Clearer for technical matters, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
A kind of valve snail as shown in Fig. 3 to Figure 13, the Novel spider plant of wire rod are shelved, comprise suspender pipe support 1, suspender case 2, boatswain chair 3 and wire coil steel fork 4, described suspender case 2 is connected with the top of described suspender pipe support 1, described boatswain chair 3 is connected with described suspender case 2, described boatswain chair 3 is provided with center of gravity lifting hole(eyelet) 6, front lifting hole(eyelet) 7,5 three lifting hole(eyelet)s of layback lifting hole(eyelet) faced upward, described center of gravity lifting hole(eyelet) 6 is positioned at described suspender pipe support 1 and loads the center-of-gravity position after suspended object, faces upward lifting hole(eyelet) 7 and described layback lifting hole(eyelet) 5 before described and on fore-and-aft direction, be positioned at respectively front side and the rear side of described center of gravity lifting hole(eyelet) 6; The bottom of front openings one side of described suspender pipe support 1 is provided with described wire coil steel fork 4, and the bottom of described suspender pipe support 1 is provided with lower reinforced rib 9, and the inner side of described suspender pipe support 1 is provided with side reinforced rib 8.
The superimposed sheet structure of described boatswain chair 3 for being formed by stacking for multilayer steel plates.
Described wire coil steel fork 4 is two that are symmetrical set.
The two ends, left and right of described suspender case 2 are connected to the left and right sides on the top of described suspender pipe support 1, and described bottom is connected to the middle part on the left and right directions of described suspender case 2.
The main improvement of the art of this patent is as follows:
(1) fixed type suspension ring change movable lifting ring into
Along with the increase of suspender size, the suspender center of gravity when unloaded is very large with the suspender deviation of gravity center of at full load.While adopting fixed type suspension ring, while guaranteeing fully loaded steady handling, when unloaded, wire coil inclination angle is too high, is difficult for inserting wire coil; While guaranteeing unloaded horizontal handling, load after wire coil, easily cause toppling.
Adopt movable suspender, different operating modes, suspension ring can be placed on different positions, with the deviation of the unloaded suspender center of gravity of balance and fully loaded overall center of gravity.
As shown in figure 11, center of gravity 10 is in the horizontal direction apart from layback lifting hole(eyelet) 5, protruding center of gravity l between center of gravity lifting hole(eyelet) 6
gshould be controlled at ± 20mm, to ensure that suspender is in the time that zero load is moved, suspension ring are in the time of layback lifting hole(eyelet) 5, Open Side Down for wire coil steel fork 4, convenient unloading, and suspension ring are in the time of center of gravity lifting hole(eyelet) 6, wire coil steel fork 4 with the α elevation angle upwards, had both guaranteed to keep stable, can not encounter steel wire coil again and cannot insert too dark.
Calculate: α=11.3-13.1 °.
Consider in stationarity, in the time of handling steel wire coil, suspension ring are faced upward lifting hole(eyelet) 7 positions front, and wire coil steel fork 4 also keeps an inclination angle upwards.Consider the extreme length 1700mm of steel wire coil, diameter 1200mm, design is when lift heavy, and steel wire coil is just on wire rod coil steel fork 4, and steel wire coil center of gravity is in front facing upward under lifting hole(eyelet) 7 vertical positions, as shown in figure 12.

Inclination angle
calculate β=4.5 °, think that suspender is in the time of handling steel wire coil, the inclination angle that entirety still keeps up, can move by held stationary, can not topple again.
(2) increase suspender overall dimensions and Maximum Loading Capacity
Suspender overall dimensions increases, and can realize the efficient handling of large-scale wire coil.Wire coil steel fork 4 degree for handling wire coil can be increased to 2m, can adapt to the efficient handling of large-scale wire coil completely.For more large-scale wire coil, and can as the case may be, increase suspender size.
Tradition suspender can only be realized monovolume handling, and the art of this patent can realize two volume handling of large-scale wire coil, and hoisting weight is brought up to more than 2 times.
(3) boatswain chair 3 of multilayer prevents Crack Extension
Traditional C type suspender when tiny crack appears in suspension ring, as do not detected in time, very easily occurs that Quick Extended causes the generation of accident in the time of work.The art of this patent adopts Multilayer Structure, even if there is Crack Extension, also can only cause damage to a veneer structure, avoids accident to occur.
More than by the detailed description of concrete and preferred embodiment the utility model; but those skilled in the art should be understood that; the utility model is not limited to the above embodiment; all within spirit of the present utility model and principle; any modification of doing, be equal to replacement etc., within all should being included in protection domain of the present utility model.
