Description

Technical Field

[0001] The utility model relates to the technical field of pipe segment maintenance, in particular to a pipe segment steam maintenance and heat insulation structure. Background Art

[0002] During the production process of shield segments, after the shield segments are formed, they need to be steamed and cured with water vapor to ensure the product quality of the shield segments. In the related technology, after the shield segments are formed, the workers will use a steam injection device, which will continuously inject water vapor to the shield segments. On the one hand, these water vapors can provide an environment with suitable humidity for the shield segments, and on the other hand, they can also provide a suitable temperature for the shield segments. The space used for existing steaming and curing segments is relatively wide. When the workers turn on the steam injection device to spray water vapor to the shield segments, the temperature around the shield segments is difficult to maintain, which causes the workers to continuously increase the amount of steam injection to maintain the temperature around the shield segments, thereby resulting in a waste of steam resources. Utility Model Content

[0003] The main purpose of the utility model is to provide a steam-cured insulation structure for pipe segments, which can effectively solve the problem that the space used for steam-curing pipe segments in the background technology is relatively wide. When the staff turns on the steam injection device to spray water vapor to the shield pipe segments, the temperature around the shield pipe segments is difficult to maintain, resulting in the staff needing to continuously increase the steam injection volume to maintain the temperature around the shield pipe segments, thereby resulting in a waste of steam resources.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A bottom plate is fixedly mounted on one side of the base, and a steam generator is fixedly mounted on the upper surface of the bottom plate;

[0007] The surface of the base close to the steam generator is penetrated by two right-angle holes, and the first right-angle tubes are fixedly installed in the two right-angle holes, and one end of the two first right-angle tubes is fixedly connected to the output end of the steam generator.

[0012] Preferably, connection grooves are formed through the surfaces of opposite sides of the two vertical plates, connection blocks are slidably arranged in the two connection grooves, and opposite sides of the two connection blocks are fixedly connected to the sealing cover.

[0013] Preferably, a rubber frame is fixedly mounted on the lower surface of the sealing cover.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] (1) The staff transports the mold carrying the shield segment to the surface of the base, and then starts the cylinder to drive the sealing cover down at its output end, so that the lower end of the sealing cover fits with the surface of the base, thereby sealing the shield segment placement position.

The temperature around the shield segment is easy to maintain. The staff does not need to continuously increase the steam spray volume to maintain the temperature around the shield segment, avoiding the waste of steam resources.

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 5 As shown, the embodiment of the utility model proposes a steam curing and heat insulation structure for pipe segments, including a base 1, vertical plates 2 are fixedly installed on both sides of the upper surface of the base 1, a horizontal plate 201 is fixedly installed on the upper surface of the two vertical plates 2, a cylinder 3 is fixedly installed in the middle of the upper surface of the horizontal plate 201, and the output end of the cylinder 3 passes through the horizontal plate 201 and is fixedly installed with a sealing cover 301. The sealing cover 301 is provided with a vent with an electronic valve inside, which is used to balance the air pressure inside the sealing cover 301;

[0024] A bottom plate 4 is fixedly mounted on one side of the base 1, and a steam generator 401 is fixedly mounted on the upper surface of the bottom plate 4;

[0025] The surface of the base 1 near the steam generator 401 is penetrated with two right angle holes 5, and the first right angle tubes 6 are fixedly installed in the two right angle holes 5. One end of the two first right angle tubes 6 is fixedly connected to the output end of the steam generator 401. The first right angle tube 6 is provided with a nozzle for spraying steam.

[0026] The staff transports the mold carrying the shield segment to the surface of the base 1, and then the staff starts the cylinder 3, so that its output end drives the sealing cover 301 to descend, so that the lower end of the sealing cover 301 fits with the surface of the base 1, thereby sealing the shield segment placement position, and then the staff starts the steam generator 401, so that it can transport steam into the sealing cover 301 through the first right-angle tube 6, so as to steam the shield segment. Under the covering and sealing effect of the sealing cover 301, the space is relatively narrow, which effectively plays a heat insulation effect, avoids heat leakage, and the temperature around the shield segment is easy to maintain. The staff does not need to continuously increase the steam spray volume to maintain the temperature around the shield segment, thereby avoiding waste of steam resources.

[0027] In another embodiment of the utility model, a three-way pipe 8 is fixedly installed on the top of the sealing cover 301 through a bracket 7, and a plurality of first atomizing nozzles 801 are fixedly installed on the body of the three-way pipe 8.

[0028] A plurality of second right-angle tubes 802 are fixedly mounted on the body of the three-way tube 8 , and a plurality of second atomizing nozzles 803 are fixedly mounted on the body of each second right-angle tube 802 .

[0029] After the sealing cover 301 descends, the two ends of the three-way pipe 8 fit with the ports of the first right-angle pipe 6, so that while the steam is ejected from the nozzle of the first right-angle pipe 6, part of the steam enters the three-way pipe 8. By arranging the three-way pipe 8, the second right-angle pipe 802, the first atomizing nozzle 801 and the second atomizing nozzle 803, the steam dispersion range is increased, so that the steam can more fully contact the surface of the shield segment, thereby increasing the steaming efficiency.

[0030] In another embodiment of the present invention, an annular sealing insert plate 804 is fixedly installed at both ends of the three-way pipe 8;

[0031] A sealing gasket 9 is fixedly mounted on one end of the two first right-angle tubes 6 , and an annular sealing slot 901 is formed on the upper surface of the two sealing gaskets 9 .

[0032] By providing the annular sealing plug plate 804 and the annular sealing slot 901, it is prevented that steam leaks from the gap between the pipe opening of the three-way pipe 8 and the pipe opening of the first right-angle pipe 6.

[0033] In another embodiment of the utility model, connection grooves 10 are formed through the surfaces of opposite sides of the two vertical plates 2, and connection blocks 1001 are slidably arranged in the two connection grooves 10. The opposite sides of the two connection blocks 1001 are fixedly connected to the sealing cover 301.

[0034] By providing the connection groove 10 and the connection block 1001 , the sealing cover 301 is prevented from being deflected when being raised or lowered.

[0035] In another embodiment of the present invention, a rubber frame 11 is fixedly mounted on the lower surface of the sealing cover 301 .

[0036] The rubber frame 11 is provided to enhance the sealing performance of the sealing cover 301 .

[0037] The working principle of this pipe segment steam curing insulation structure:

[0038] When in use, the staff transports the mold carrying the shield segment to the surface of the base 1, and then the staff starts the cylinder 3, so that its output end drives the sealing cover 301 to descend, so that the lower end of the sealing cover 301 fits with the surface of the base 1, thereby sealing the shield segment placement position, and then the staff starts the steam generator 401, so that it can transport steam into the sealing cover 301 through the first right-angle tube 6, so as to steam the shield segment. Under the covering and sealing effect of the sealing cover 301, the space is relatively narrow, which effectively plays a heat insulation effect, avoids heat leakage, and the temperature around the shield segment is easy to maintain. The staff does not need to continuously increase the steam spray volume to maintain the temperature around the shield segment, thereby avoiding waste of steam resources.

[0039] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
