Technical Field

[0001] The utility model relates to the field of installation of steel-sheathed steel insulation pipes, and particularly to an installation bracket for steel-sheathed steel insulation pipes. Background Technique

[0002] The steel-sheathed steel insulation pipe is a commonly used insulation pipe, which is widely used in industries such as heating, petroleum, and chemical industry. It is composed of an inner steel pipe, an insulation layer, and an outer steel pipe. When laying the steel-sheathed steel pipe, it is usually composed of multiple pipe segments. And in order to improve the stability of the steel-sheathed steel pipe during use and the strength of the connection of the steel-sheathed steel pipe, installation brackets are usually arranged at the joints of the pipes to support them.

[0003] After retrieval, for the Chinese patent "An installation bracket for steel-sheathed steel insulation pipes", the authorization announcement number is "CN209524235U". When installation is required, first install the installation base on the required plane through fixing bolts, then connect the inner guard plate with the upper casing and the lower casing, and then use the upper casing and the lower casing to sleeve the equipment outside the steel-sheathed steel insulation pipe, and use the first connection bolts to fix the upper casing and the lower casing. The structure is reasonable, the operation is simple, and it is convenient to use.

[0004] Although the above application can support the steel-sheathed steel insulation pipe by using the upper casing and the lower casing, there is a gap between the inner guard plate and the surface of the steel-sheathed steel pipe after fixation, so that external moisture and humidity will enter between the inner guard plate and the pipe, which is likely to cause corrosion at the joints of the pipe, thus affecting the normal use of the pipe.

[0005] Therefore, an installation bracket for steel-sheathed steel insulation pipes is proposed to solve the above problems. Content of the Utility Model

By sequentially rotating the two bidirectional lead screws, under the action of the corresponding moving plate, round rod and extrusion plate, the gas in the air storage frame enters the two groups of arc-shaped air bags and the two sealing air bags to make the air bags expand.

[0009] Preferably, a plurality of sealing gaskets are embedded and installed on both sides of the inner wall of the fixing ring, and the arc-shaped air bags are arranged between adjacent two sealing gaskets.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] In specific implementation: As Figures 1-5 shown, a mounting bracket for a steel-sheathed steel thermal insulation pipe includes: a fixed seat 1, and a sealing mechanism 2 is provided at the top end of the fixed seat 1; among them, the sealing mechanism 2 includes two fixing rings 21, the lower end of the surface of the lower fixing ring 21 is fixedly connected to the top end of the fixed seat 1, both ends of the two fixing rings 21 are fixedly connected with air storage frames 22, a pressing plate 23 is slidably connected to the inner wall of the air storage frame 22, one end of the air storage frame 22 is connected with an exhaust pipe 24, the other end of the exhaust pipe 24 penetrates through the fixing ring 21 and is communicated with a fixed pipe 25, a plurality of arc-shaped air bags 26 are embedded and installed on both sides of the inner wall of the fixing ring 21, and the plurality of arc-shaped air bags 26 are communicated with the corresponding fixed pipes 25, and sealing air bags 27 are embedded and installed on both sides of the bottom end of one of the fixing rings 21, and both ends of the sealing air bags 27 are communicated with the bottom ends of one group of arc-shaped air bags 26.

[0025] Place the device at the connection of the steel-sheathed steel thermal insulation pipe, and use fastening bolts to fixedly install the two fixing rings 21, then the steel-sheathed steel thermal insulation pipe can be supported.

[0026] The air storage frame 22 is filled with gas. The arc-shaped air bags 26 on both sides of the inner wall of a single fixing ring 21 are taken as a group. When the two fixing rings 21 are fixed to the steel-sheathed steel thermal insulation pipe, the two groups of arc-shaped air bags 26 and the two sealing air bags 27 will form a complete sealing ring at the connection of the two fixing rings 21 and the steel-sheathed steel thermal insulation pipe.

[0027] As Figure 3 and Figure 5 shown, the sealing mechanism 2 further includes a fixed block 28 fixedly connected to the surface of the fixing ring 21, a bidirectional lead screw 29 is rotatably connected to the inner wall of the fixed block 28, a moving plate 210 is threadedly connected to the surface of the bidirectional lead screw 29, a round rod 211 is fixedly connected to one side of the moving plate 210, and the other end of the round rod 211 penetrates into the corresponding air storage frame 22 and is fixedly connected to one side of the pressing plate 23.

[0028] The threads of the two moving plates 210 connected to the bidirectional lead screw 29 are opposite. Therefore, when the bidirectional lead screw 29 rotates, it will drive the two moving plates 210 to move towards each other. After the two fixing rings 21 are fixed, rotate the two bidirectional lead screws 29 respectively to drive the two moving plates 210 to approach each other. At this time, the two moving plates 210 drive the corresponding round rods 211 to move simultaneously to push the pressing plate 23 to squeeze the gas in the air storage frame 22, so that the gas sequentially enters the plurality of arc-shaped air bags 26 through the exhaust pipe 24 and the fixed pipe 25, causing the arc-shaped air bags 26 to expand and seal the connection between the fixing ring 21 and the steel-sheathed steel pipe.

[0029] When the bidirectional lead screw 29 of the upper fixed ring 21 is rotated to squeeze the gas in the air storage frame 22 by the corresponding pressing plate 23, the gas will enter the sealing airbag 27 through the arc-shaped airbag 26 at the same time, causing the sealing airbag 27 to expand and seal the connection between the two fixed rings 21. The air storage frame 22 is filled with sufficient gas, and rotation can be stopped after sealing is completed.

[0030] As Figure 3 shown, a plurality of sealing gaskets 212 are embedded and installed on both sides of the inner wall of the fixed ring 21, and the arc-shaped airbag 26 is arranged between two adjacent sealing gaskets 212. The arc-shaped airbag 26 and the sealing gasket 212 are arranged in an alternating manner. One side of the sealing gasket 212 is fixedly connected to the inner wall of the fixed ring 21, and the other side is fixedly connected to the surface of the arc-shaped airbag 26.

[0031] As Figure 5 shown, a first bolt 213 is threadedly connected to the inner wall of the fixed block 28, and the bottom end of the first bolt 213 penetrates into the interior of the fixed block 28 and is rotatably connected to a clamping block 214. The surface of the clamping block 214 is curved in an arc shape, and the bending radian is the same as the bending radian of the surface of the bidirectional lead screw 29.

[0032] After sealing is completed, the first bolt 213 is rotated to push the clamping block 214 downward. A card slot corresponding to the clamping block 214 is provided on the surface of the bidirectional lead screw 29. When the clamping block 214 moves downward, it will be clamped with the card slot, thereby limiting the bidirectional lead screw 29.

[0033] As Figure 5 shown, a limiting rod 215 is fixedly connected to the upper end of the surface of the clamping block 214, and the top end of the limiting rod 215 penetrates out of the fixed block 28. The surface of the limiting rod 215 is slidably connected to the inner wall of the fixed block 28 to limit the up and down movement of the clamping block 214.

[0034] As Figure 3 shown, one end of the bidirectional lead screw 29 is fixedly connected to a knob, and a plurality of annularly distributed grooves are provided on the surface of the knob. The operator can rotate the knob to drive the bidirectional lead screw 29 to rotate.

[0035] When the utility model is in use, place the device at the connection of the steel-sheathed steel insulation pipe, and use the fastening bolts to fixedly install the two fixing rings 21, then the steel-sheathed steel insulation pipe can be supported and fixed. After this step is completed, rotate the two-way lead screws 29 corresponding to the two fixing rings 21 respectively. When the two-way lead screws 29 rotate, they drive the two moving plates 210 to approach each other. At this time, the two moving plates 210 drive the corresponding round rods 211 to move simultaneously, pushing the extrusion plate 23 to extrude the gas in the air storage frame 22, so that the gas passes through the exhaust pipe 24 and the fixed pipe 25 and enters multiple arc-shaped air bags 26 at the same time, causing the arc-shaped air bags 26 to expand and seal the connection between the fixing ring 21 and the steel-sheathed steel pipe. And when the gas enters the arc-shaped air bags 26 in the upper fixing ring 21, the gas will enter the sealing air bags 27 through the arc-shaped air bags 26 at the same time, causing the two sealing air bags 27 to expand simultaneously to seal the connection between the two fixing rings 21. After the two groups of arc-shaped air bags 26 and the two sealing air bags 27 expand, the sealing is completed, forming a complete sealing ring at the connection between the two fixing rings 21 and the steel-sheathed steel insulation pipe. After the sealing is completed, rotate the first bolt 213 to push the block 214 to move downward and engage with the card slot on the surface of the two-way lead screw 29 to limit the two-way lead screw 29.

[0036] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
