Problems solved by technology

Working in high temperature conditions in the long run will inevitably lead to the aging of the cushioning limit plastic sleeve C, the deformation range will drop sharply or even aging, and the powder will automatically lose after impact pressure, which will easily produce abnormally large fit clearances. This will cause the weighing platform to shake greatly with the shaking of molten steel, and there may be extremely serious safety accidents such as molten steel splashing and hurting the human body.

Embodiment 1

[0022] see figure 2 and 3 , the present invention is provided with annular bushing 1 (circular bushing) and annular casing 2 (annular annular casing). Both the annular bushing 1 and the annular casing 2 are metal annular casings. The annular bush 1 is a split structure, which is composed of the upper annular bush 11 and the lower annular bush 12, which facilitates the installation of the annular bush 1 into the annular shell 2 (when the buffer volume is small, there is no large axial Extended needs can also be integrated structure). The gap P0 between the upper ring bushing 11 and the lower ring bushing 12 is the boundary, and the upper ring bushing 11 and the lower ring bushing 12 are symmetrically arranged up and down. The radial flange 111 at the upper end of the upper annular bushing 11 is fixedly connected (welded or threaded) to the upper end of the annular casing 2, and the radial flange 112 at the lower end of the lower annular bush 12 is fixedly connected (welded ...

Embodiment 2

[0025] Similar to Embodiment 1, the difference is that this embodiment is a universal buffer guide sleeve with a three-stage buffer structure. see Figure 4 and 5 , The upper annular bushing 11 and the lower annular bushing 12 are arranged symmetrically up and down in the axial direction. There are first-level buffer gap a, second-level buffer gap b, and third-level buffer gap c, where a Figure 4 and 5 The rest of the labels in are correspondingly consistent with Example 1.

Abstract

The invention discloses a universal buffering guide sleeve and relates to a buffering and spacing device. The universal buffering guide sleeve provided by the invention can avoid ageing and effectively resist a lateral force. The universal buffering guide sleeve is provided with an annular lining and an annular shell sleeve, wherein the upper end of the annular lining and the upper end of the annular lining are fixedly connected; the lower end of the annular lining is fixedly connected with the lower end of the annular shell sleeve; the outer surface of the annular lining is provided with at least four annular elastic grooves; a flange formed between every two adjacent annular elastic grooves is an anti-impact protective ladder; a radial buffering gap is arranged between each anti-impact protective ladder and the inner surface of the annular shell sleeve; the annular lining is provided with at least four longitudinal rigidity reduction grooves; and each rigidity reduction groove radially extends from the inner surface of the annular lining.

Description

technical field [0001] The invention relates to a buffer limit device, in particular to a universal buffer guide sleeve which can effectively resist lateral force. Background technique [0002] Generally speaking, any weighing instrument will take the limit into consideration when designing its upper and lower weighing platforms. The bale scales of iron and steel enterprises have special requirements for the limit of the weighing platform. Its limit is not only to ensure the accuracy and repeatability of the scale, but also, very importantly, it must be able to withstand the impact of lateral force. Since the steel ladle hoisted by the crane for weighing will inevitably hit the weighing platform before it is put in place, the weight of the steel ladle ranges from a few tons to hundreds of tons. When the crane is operating, the ladle cannot be placed very accurately, and it is inevitable that it will be sideways. to impact the weighing platform of the bale scale. In order t...
