Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Embodiment
This kind of many bellows of adhering film is hung and is claimed to comprise two parallel up and down stiffener plate, i.e. stiffener plate 1, stiffener plate 22, the film capsule 3 that two or more is made with the impermeable flexible material not easily extended, a tensimeter 8, and two U bolts 7 and standard component, film capsule 3 is between two stiffener plate two face A1 and B1 in opposite directions, three together constitutes an enclosure space, this enclosure space is bagel shape, is filled with liquid at this enclosure space, and tensimeter 8 is communicated with it.
When stiffener plate is stressed, will produce certain pressure in enclosure space, tensimeter 8 illustrates stressed size by measuring pressure gauge, thus tensimeter 8 can illustrate the weight of weighed object.Its principle is: be directly proportional to the radius-of-curvature of this part to the stress of the stiffener plate not membraneous material of contact position, the stress of other parts is less.When the distance of A1 and B1 is less, radius-of-curvature is also less.Thus as long as the distance of A1 and B1 is enough little, film just can bear enough large pressure.
Enclosure space is bagel shape.The cross section of film capsule 3 outer edge and stiffener plate not contact position is the semicircle of radius=R.If pressure=P, then drawing stress=P × the R of this place's film.The stress at other place of film is less.Find out thus, as long as R is enough little, the stress of film is just enough little.For this reason, need the distance of A1 and B1 enough little, also require that the area of A1 and B1 is enough large, film is only contacted with A1 and B1 face.
The intensity of existing chemical fabric can fully meet R=0.01 rice, the requirement of P=2MP.This is equivalent to the unit area bearing capacity of 200t/m, and this is more than sufficient for general weighing.
Two common steel plates of stiffener plate make, and the fluid-tight chemical fabric of film capsule 3 makes, and film capsule 3 is placed between two stiffener plate, two face A1 and B1 in opposite directions, connects with bonding or flange screw 9.Fig. 1, Fig. 2 are another structural representations connected realizing film capsule 3 and stiffener plate by bonding method, the U bolt 7 of opening upwards can be faced in Fig. 1, Fig. 2 can face the U bolt 7 that Open Side Down, as shown in Figure 1, Figure 2, the middle part of film capsule 3 is bonded in stiffener plate one, stiffener plate two, and the remainder of film capsule 3 is not bonded in stiffener plate one, stiffener plate two.Fig. 3, Fig. 4 are the structural representations connected realizing film capsule 3 and stiffener plate with flange and screw 9, and the U bolt 7, Fig. 4 can facing opening upwards in Fig. 3 can face the U bolt 7 that Open Side Down.As Fig. 3, Fig. 4, film capsule 3 uses inner flange 11, screw 9, outside flange 10 to be connected in two stiffener plate respectively.
Film capsule 3 and stiffener plate form an enclosure space jointly, and enclosure space is bread cast, and this enclosure space is filled with liquid, and tensimeter 8 is fixed in a stiffener plate, is communicated with enclosure space by a hole.Stiffener plate is enough large, and make film capsule 3 only contact two stiffener plate face A1 and B1 in opposite directions, the reading of tensimeter 8 is demarcated by experiment.
Weigh for adapting to lifting state, in the scope being less than enclosure space internal diameter, at the middle part of each stiffener plate, there are four holes, a U bolt 7 passes the two non-conterminous holes of stiffener plate from bottom, above, the upper surface place of stiffener plate engages with two nuts 5 and split pin 4, and the lower surface of another U bolt 7 from top through remaining hole stiffener plate below engages with two nuts 5 and split pin 4.Form upper and lower two suspension ring.
For preventing overload, preventing two stiffener plate from having excessive relative displacement, having four annular rings 6 be between A1 and B1 to be enclosed within U bolt 7.For improving measuring accuracy, the reading of tensimeter 8 is demarcated by actual measured value.Because the bending resistance of film is very little, therefore the measuring error caused due to the deadlock of film is very little.
