Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe.
A kind of overload protection device detector, including U-shaped beam 1, chain sling 2, the two ends of chain sling 2 are hung on the two-arm of U ellbeams 1, hung
Bottom plate 9 is placed on chain 2, pitman 7 passes through bottom plate 9 and connecting plate 12, and puts in the sleeve 6 being located above connecting plate 12, set
Cylinder group is made up of 3 adjustable sleeves, and one end of sleeve group is the sleeve 6 for being socketed pitman, and the other end is adjustment structure, is adjusted
Section nut can change the length of sleeve group, and connecting plate 12, to be fixedly connected, connects with pitman 7 between bottom plate 9 and connecting plate 12
Take over the baton 7 outside sets spring 8, and the top of bottom plate 9 is set sets proximity switch 11 on magnet steel 10, connecting plate 12, and proximity switch 11 is in magnet steel
Directly over 10, sleeve 6 coordinates with being located at the leading screw 5 of the lower section of installing plate 4.
Installing plate 4 is steel plate of the upper and lower surface with center line and scale, with enough rigidity, to reduce because stress becomes
Shape produces influence on accuracy of detection, and the top of installing plate 4 sets jack 13, level meter 3, and jack 13 fills for the generation of detector power
Put, from hydraulic jack, level meter 3 be used to detect after force installing plate 4 whether level, it is ensured that level meter 3 during use
In bubble do not offset between two parties, to ensure uniformly to apply pressure to each sleeve group.
Top plate 14 is set below U-shaped beam 1, top plate 14 is on the surface of jack 13, the adjusting screw rod of jack 13 and top
Plate 14 is welded, height adjustable, and the position of jack 13 is by calculating and aiding in center line and scale with installing plate 4 to determine.
Chain sling 2 uses hanging belt, and U-shaped beam 1, hanging belt constitute hitch, and the two-arm of U cross girders 1 respectively has an exhausting hole, push up
Plate 14 is located at the lower section of U-shaped beam 1 and can adjust the position of U-shaped beam with horizontal sliding, and hanging belt is simultaneously placed in the middle through bottom plate 9, hangs
Dress is fixed on two ends using bolt and nut group in the through hole of U-shaped beam two-arm, the maximum distance of limitation U cross girders and bottom plate 9, so as to
Jack 13 sequentially passes through installing plate 4, sleeve pipe group for support with U-shaped beam 1 and is downwardly applied to pressure to bottom plate 9.
The lower end hanging steel rope and machine (not represented in figure) of pitman 7, power are delivered to spring 8, and connecting plate 12 is consolidated
It is scheduled on pitman 7, is moved up and down with the flexible of spring 8, corresponding load is loaded in machine, during compared to zero load, bottom plate
Be subject to one overload load, thus spring 8 produce a decrement, proximity switch 11 is corresponding to the distance of magnet steel 10 to be shortened,
Now overload protection device is just acted, and such as shifts to an earlier date or backward action is undesirable, at this moment adjust proximity switch 11 and magnetic
The distance between steel 10 so that just alarm overloads machine, presses the handle of jack 13, is downwardly applied to pressure, lifts
Band is tightened, and spring 8 produces compression, and proximity switch 11 reduces with the spacing of magnet steel 10, the pressure of the pressure gauge display response of jack 13
Intensity values.
Show by embodiment, detect data standard deviation it is smaller, detector repeatability, stability it is good, relative error compared with
It is small, detect that the degree of accuracy of data is high, meet the requirement to overload protection device security performance, the light and handy portable of this detector mechanism
Band, it is simple to operate, testing cost, labor intensity are greatly reduced, detection efficiency is greatly improved, and application prospect is more wide.
It should finally be noted above example is only the more representational example of the utility model.Obvious the utility model
Above-described embodiment is not limited to, there can also be many deformations.It is every according to technical spirit of the present utility model to above example institute
Any simple modification, equivalent variations and the modification made, are considered as belonging to protection domain of the present utility model.
