Three guide pillars of the present invention and band limit function disc spring hanger, because the below being positioned at pressing plate on directional post is threaded limited location nut, before running when hydraulic pressure or overload test, can stop nut be rotated to contacting with the bottom surface of pressing plate, utilize stop nut load, disc spring does not stress, and does not now produce displacement, ensure that normal test.Stop nut can be rotated down after examination, make stop nut have certain interval apart from pressing plate, when ensure that normal operation, have certain displacement amount.Simultaneously the normal displacement that pressing plate is downward when running also is conditional, unlikely disc spring is depressed into limit position, extends its working life; Pressing plate and base plate are disc-shape, and directional post is three and even circumferential is arranged, and greatly saves the consumption of material, decreases amount of finish, cost of material and processing cost are decreased; Stiffening plate between pressing plate and disc spring adds the intensity of pressing plate, can be thinning by thickness of compressive plate during processing and fabricating, simultaneously for stop nut leaves certain space, has that overall structure is simple, the advantage of long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the specific embodiment of the invention;
Fig. 2 is the schematic top plan view shown in Fig. 1.
Embodiment
As shown in Figure 1, 2: 1 is base plate, 5 is pressing plate, and base plate 1 and pressing plate 5 are disc-shape.3 is directional post, and the lower end of directional post 3 is processed with screw thread and is connected with the tapped hole on base plate 1.The top of directional post 3 penetrates in the hole on pressing plate 5 and upper tip protrudes upward, and the upper tip of directional post 3 has been threaded directional post nut 6, and directional post nut 6 be double nut and the back of the body is tightly mutually.Above-mentioned directional post 3 is three, is uniformly distributed in a circumferential direction.The below that each directional post 3 is positioned at pressing plate 5 is threaded limited location nut 4, and stop nut 4 is double nut and the back of the body is tight mutually.Rotate stop nut 4 during normal operation to make to leave gap 10 between itself and pressing plate 5.The height in gap 10 is the maximum displacement of pressing plate 5 when stressed.Pull bar 8 is positioned at the center hole of pressing plate 5 and base plate 1, and the upper end of pull bar 8 protrudes upward from the center hole of pressing plate 5, and the upper tip of pull bar 8 has been threaded pull-rod nut 9, and pull-rod nut 9 is double nut and the back of the body is tight mutually.The bottom of pull bar 8 is stretched out downwards for carrying from the center hole of base plate 1.The below that pull bar 8 is positioned at pressing plate 5 is set with stiffening plate 7, and stiffening plate 7 is also in disc-shape.Between base plate 1 and stiffening plate 7, disc spring 2 is provided with outside pull bar 8.
During use, by base plate 1 by this hanger supports on foundation beam or support body, the lower bottom bearing of pull bar 8 is used for fixing lifting pipeline or equipment, disc spring 2 is pressed to by pressing plate 5, stiffening plate 7 after pull bar 8 is stressed, last by disc spring 2 load, the downward maximum displacement of stressed rear fender 5 is identical with gap 10 and to carry out overload by stop nut 4 spacing.
When carrying out hydraulic pressure or overload test before operation, stop nut 4 can be rotated and contact with the bottom surface of pressing plate 5, utilize stop nut 4 load, disc spring 2 does not stress, and does not now produce displacement, ensure that normal test.
Along with install the industrial pipeline of the industry such as electric power, chemical industry or equipment and fixing etc. requires more and more higher, existing spring hanger has been not enough to meet the large load exceeding standard, the large demand such as intensity and spatial constraints.This suspension bracket compensate for the deficiencies in the prior art.The space that it needs is less, and can be issued to great load in the situation of very little thermal walking, can resist larger load impacting, simultaneously its applied code load or comparatively side crops industry too, and accommodation is large.And most pipeline or equipment all will carry out the test such as hydraulic pressure, overload before commencement of commercial operation, be used for the stability of testing pipes or equipment and Security.Therefore, the limit function of this suspension bracket will become one of requisite function of disc spring hanger.Because the object of limit function is exactly to bear pipeline or equipment pre-running test load, the limited device of the overload of test is allowed to absorb, thus avoid disc spring itself be subject to overload effect and damage, guarantee the safe operation of disc spring hanger, reduce the application material of disc spring hanger simultaneously.
