Description

Technical Field

[0001] The invention relates to the technical field of spring vibration isolators, in particular to an outer sleeve of a spring vibration isolator. Background Art

[0002] Spring isolators are the most commonly used isolators, made of steel springs or rubber. They are available in spiral, disc, ring and plate shapes. Their advantages are: large static compression, low natural frequency, good low-frequency vibration isolation, resistance to erosion by oil and water, no temperature changes affecting performance, no aging, no creep, etc. In practical applications, the isolator is usually provided with an outer sleeve.

[0003] In the prior art, the outer sleeve of the vibration isolator is circular in shape, and its lifting block and supporting block are both welded. This technology has the following disadvantages:

[0004] 1. The outer sleeve cannot be replaced after being embedded, and the jacking plate and support plate are fixed to the sleeve wall by welding. The weld is the weakest part of the sleeve, and it is difficult to ensure its reliability during long-term use. In addition, there are many welds, which makes it difficult to ensure the high accuracy of the welded parts and the welding strength of multiple welded parts. Once damaged, it is difficult to repair, and even after repair, it is difficult to restore the original working state;

[0005] 2. The existing floating slab ballast jacking scheme adopts the method of placing adjustment gaskets under the fixed outer sleeve support surface to achieve jacking. However, the base has a large error during the construction process. According to on-site statistics, the thickness of the gaskets required at different positions basically ranges from 40 to 60 mm, resulting in a large waste of gasket materials. At the same time, the gaskets need to be stacked layer by layer, and the on-site construction operation time is long. Summary of the invention

[0006] In order to overcome the above technical defects, the object of the present invention is to provide an outer sleeve of a spring isolator with adjustable support height.

[0007] The present invention discloses an outer sleeve of a spring vibration isolator, which includes a sleeve body. A plurality of axial slideways are provided on the wall of the sleeve body, and the plurality of slideways are arranged along the circumferential direction of the sleeve body. The wall surface of the sleeve body at the position where the slideways are provided is in a "ji" shape. The slideway includes a jacking part and a limiting part. The jacking part is communicated with the upper end opening of the sleeve body. A plurality of first bumps are arranged axially in the jacking part. The plurality of first bumps are parallel and equidistant, covering the jacking part. The first bumps are wedge-shaped. A sealing plate is provided at the bottom of the limiting part, and the sealing plate is arranged between the sleeve body and the limiting part to seal the bottom of the slideway. It further includes a plug block, and the plug block includes a plurality of second bumps that cooperate with the first bumps. The plurality of second bumps are parallel and equidistant. The second bumps are wedge-shaped, and the second bumps and the first bumps are in wedge-shaped cooperation, so that the plug block is arranged on the jacking part to form a supporting surface.

[0008] Preferably, the plug block includes two of the second bumps, and a first through hole is provided on the plug block, and the first through hole penetrates through the two second bumps.

[0009] Preferably, it further includes an annular bottom plate, and the bottom plate is arranged around the lower end opening of the sleeve body, and the inner circular surface of the bottom plate is connected to the outer surface of the sleeve body. A plurality of rib plates are provided between the bottom of the sleeve body and the bottom plate, and the plurality of rib plates are evenly arranged along the circumferential direction of the sleeve body.

[0010] Preferably, a plurality of groups of steel bar support frames are further provided on the sleeve body. Each group of steel bar support frames includes two steel bar support frames. The two steel bar support frames in the same group are respectively arranged on both sides of the sleeve body and are oppositely arranged.

[0011] Preferably, it further includes a flange, and the flange is arranged on the top of the sleeve body. A plurality of second through holes are provided on the flange, and the plurality of second through holes are equidistantly arranged along the circumferential direction of the sleeve body, and threads are provided in the second through holes.

[0012] Preferably, the limiting part is communicated with the lower end opening of the sleeve body, and the sealing plate is the bottom plate.

[0013] Preferably, the number of the slideways is three, and the three slideways are evenly arranged along the circumferential direction of the sleeve body.

[0014] Preferably, the number of the slideways is four, and the four slideways are evenly arranged along the circumferential direction of the sleeve body.

[0015] Preferably, the distance between several first protrusions is 20 mm, the distance between several second protrusions is 20 mm, and several first protrusions cooperate with several second protrusions so that the plug is arranged on the lifting portion to form the supporting surface.

[0016] Preferably, the distance between the first bumps is 10 mm, and the distance between the second bumps is 10 mm.

[0017] Compared with the prior art, the above technical solution has the following beneficial effects:

[0018] 1. The plug is matched with the slideway, replacing the supporting structure fixed to the sleeve wall in the prior art, and is detachable. The second protrusion on the plug is matched with the first protrusion of the lifting part of the slideway to form a claw support surface. After the lifting work is completed, the plug can be removed. The fixed supporting structure of the prior art avoids the situation of failure and damage due to force, and simplifies the structure of the sleeve body;

[0019] 2. Since the lifting portion includes several first protrusions in the axial direction, the plug can be selected to cooperate with the first protrusions at different height positions, so that the position of the plug (i.e., the supporting structure) is adjustable, so that the gap between the plug and the top surface of the spring isolator is minimized, thereby minimizing the thickness of the adjustment gasket and avoiding waste of adjustment gasket material;

[0020] 3. The steel bar support frame group and the sleeve body are tied together through steel bars, so that a better anchoring effect can be achieved between the sleeve body and the concrete; the rib plate makes the connection between the sleeve body and the base plate more stable.
