The purpose of the utility model can also further realize through following technical measures.
Aforesaid hoisting permanent magnet lifting force tester is provided with oscillating bearing in the hinge ear on the wherein said oil cylinder, and the lateral pin I is passed oscillating bearing, oil cylinder hinged seat, and lateral pin I two ends are fixed on the oil cylinder hinged seat.
Aforesaid hoisting permanent magnet lifting force tester; Wherein said flap seat comprises inverted U-shaped seat, screws screw, lateral pin II at inverted U-shaped seat top; The pulling force sensor lower end is connected with screw retention, and the lateral pin II is crossed inverted U-shaped seat lower end, and the hoisting permanent magnet top is suspended on the lateral pin II through hoist cable.
The utility model is simple in structure; Easy to operate; When hydraulic cylinder piston rod rises, will inhale the slow pull-up that makes progress of hoisting permanent magnet on base, be pulled up in the process at hoisting permanent magnet through playing a flap seat, hoist cable; Lifting power between itself and the base is delivered to through pulling force sensor and shows actual lifting power value on the dynamometer; The indicating value that breaks away from base moment dynamometer at hoisting permanent magnet is maximum lifting power value, and the utility model detects safe ready, the result is accurate, has guaranteed the safe and reliable of hoisting operation.
Advantage of the utility model and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide with reference to accompanying drawing as an example.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Like Fig. 1, shown in Figure 2; The utility model comprises loading frame 1, be fixed on the oil cylinder hinged seat 2 of entablature 11 middle part downsides, be successively set on the holder below oil cylinder 3, pulling force sensor 4, play flap seat 5; Entablature 11 is welded side by side by three joist steel and forms; Entablature 11 downsides are strengthened through the diagonal bar 14 that is connected with upright arm 12, improve the bending strength of entablature 11.Upright arm 12 is arranged on loading frame 1 both sides, and its two ends are fixedly connected into the loading frame 1 of sealing respectively through securing member and entablature 11, base 13.Oil cylinder hinged seat 2 is fixed on entablature 11 downsides through a plurality of unit bolt nuts 21 that bear pulling force.Oil cylinder 3 one sides are connected with hydraulic system through pipeline; Hinge ear 31 is arranged between the oil cylinder hinged seat 2 both sides otic placodes 22 on the oil cylinder; Oscillating bearing 8 is arranged on and cuts with scissors in the ear 31 on the oil cylinder; Lateral pin I 7 is passed oscillating bearing 8, oil cylinder hinged seat 2, makes on the oil cylinder hinge ear 31 hinged through lateral pin I 7 and oil cylinder hinged seat 2.Lateral pin I 7 two ends are fixed on the oil cylinder hinged seat 2 through the back-up ring location.During test, oil cylinder 3 can be swung within the specific limits, avoids the harmful effect of unbalance loading to parts such as oil cylinder piston bar, orienting sleeves.Oil cylinder lower end piston rod end is fixedly connected through screw thread with pulling force sensor 4 upper ends, and pulling force sensor 4 lower ends are fixedly connected through screw 52 with flap seat 5 upper end.
Play flap seat 5 and comprise inverted U-shaped seat 51, screw screw 52, lateral pin II 53 at inverted U-shaped seat 51 tops, inverted U-shaped seat 51 can solid forging or casting processing form, also can be welded through three block plates, the inverted U-shaped seat 51 of present embodiment adopts welded structures.Lateral pin II 53 is crossed inverted U-shaped seat 51 lower ends, its two ends respectively with inverted U-shaped seat 51 lower end clearance fit, pulling force sensor 4 is connected with dynamometer through output line.
When carrying out the test of lifting power, earlier hoisting permanent magnet 9 is inhaled on base 13, again hoisting permanent magnet 9 tops are suspended on the lateral pin II 53 through hanging bundle 10.The primer fluid pressing system; Driving oil cylinder 3 lower end piston rods rise, thereby with the hoisting permanent magnet 9 slow pull-up that makes progress, break away from the moment of bases 13 when hoisting permanent magnet 9; Its lifting power reaches maximal value, can observe the hoisting permanent magnet 9 maximum lifting power indicating values of demonstration at dynamometer.
