Abstract
Description
Technical Field
[0001] The present application relates to the technical field of pipeline repair, and in particular to a hose binding structure. Background Art
[0002] The trenchless pipeline lining repair technology is a technology that utilizes the original pipeline location resources without excavation or minimizing excavation, and installs a new lining inside the existing pipeline to restore or improve the function and lifespan of the pipeline.
[0003] During pipeline lining repair, it is necessary to pull a hose into the pipeline, then block both ends of the hose, then bind both ends located outside the pipeline, and finally fill the hose with steam to make the hose expand and tightly adhere to the inner sidewall of the pipeline, ultimately achieving the repair of the pipeline.
[0004] However, since the length of the hose is greater than the length of the pipeline, both ends of the hose located outside the pipeline have no pipeline support, so that excessive expansion is likely to occur between the hose located outside the pipeline and the binding position, which easily causes damage to the hose. Moreover, the hose is also prone to pulling the hose to move during excessive expansion, causing the hose to slip off from the binding position, thereby reducing the stability during repair. Summary of the Utility Model
[0005] In order to reduce the probability of excessive expansion between the hose and the binding position, the present application provides a hose binding structure.
[0006] The hose binding structure provided by the present application adopts the following technical solutions:
[0007] A hose binding structure includes a head bag disposed on the pipeline and supporting the outer sidewall of the hose. A support member is disposed inside the hose to facilitate inflation of the inside of the hose and block the end face of the hose. A binding member is disposed on the head bag to bind the head bag and the hose to the support block.
[0008] By adopting the above technical solutions, the hose is inserted into the pipeline, the head bag is wrapped around the end of the hose, the end of the head bag close to the pipeline is fixedly installed on the pipeline, the head bag and the end of the hose away from the pipeline are bound to the support member by the binding member, and inflation gas is introduced into the hose through the support member, so that the hose expands. The hose located outside the pipeline expands and abuts against the head bag after expansion. The head bag abuts against and supports the end of the hose, reducing the probability of excessive expansion between the hose and the binding position.
[0009] Furthermore, the end of the head bag close to the pipeline is a cylindrical structure, and the head bag is made of a breathable material to facilitate the expansion of the hose and its tight adhesion to the inner sidewall of the head bag.
[0010] By adopting the above technical solution, when gas is introduced into the hose and the hose expands, the gas between the hose and the tie bag is discharged through the tie bag, and the tubular tie bag facilitates the tight support of the outer side wall of the hose.
[0011] Furthermore, the support member is of a cylindrical structure. The support member is hermetically connected to the end face of the hose through a binding member, and an air inlet pipe for facilitating the introduction of expansion gas into the hose is fixedly installed on the support member.
[0012] By adopting the above technical solution, the outer side wall of the support member supports the inside of the hose and the tie bag. When the binding member locks the tie bag and the hose on the support member, the support member seals the end face of the hose, and it is convenient to introduce expansion gas into the sealed hose through the air inlet pipe, so as to make the hose tightly press against the inner side walls of the pipeline and the tie bag.
[0013] Furthermore, a plurality of anti-slip convex rings are arranged on the support member, and the plurality of anti-slip convex rings cooperate with the binding member to prevent the hose and the tie bag from slipping on the support member.
[0014] By adopting the above technical solution, the binding member binds the tie bag and the hose to the support member, and at the same time, the binding member presses part of the hose and the tie bag into the gap between adjacent two convex rings, thereby improving the fixing effect of the tie bag, the hose and the support member, and reducing the probability of mutual slipping between the hose and the tie bag and the support member during use.
[0015] Furthermore, one end of the tie bag far from the support member extends into the pipeline and presses tightly against the inner side wall of the pipeline, and the hose presses the tie bag against the inner side wall of the pipeline.
[0016] By adopting the above technical solution, one end of the tie bag close to the pipeline is extended into the pipeline. When the hose expands, it presses tightly inside the tie bag, so as to press the tie bag against the pipeline, thereby preventing the tie bag from slipping towards the end far from the pipeline.
[0017] Furthermore, the tie bag is detachably arranged on the pipeline through a fixing component, and the fixing component includes:
[0018] A first flange, which is arranged on the end face of the pipeline;
[0019] A second flange, which cooperates with and locks the first flange, and the second flange is arranged on the inner side wall of the second flange at the end of the tie bag close to the pipeline;
[0020] Fixing bolts, which are arranged on the second flange and are used to lock the second flange on the first flange.
[0021] By adopting the above technical solution, one end of the tying bag close to the pipeline is fixedly installed on the second flange, and the second flange is detachably installed on the first flange through fixing bolts and fixing nuts, so as to detachably install the tying bag on the pipeline.
[0022] Furthermore, a pressure detector is arranged on the support member, and the pressure detector is communicated with the inside of the hose and used for detecting the air pressure value inside the hose.
[0023] By adopting the above technical solution, after inflating gas into the hose, the pressure value inside the hose is accurately detected in real time by the pressure detector, thereby reducing the probability of damage to the hose caused by excessive pressure value inside the hose.
[0024] Furthermore, a pressure relief pipe is arranged on the support member, the pressure relief pipe is communicated with the inside of the hose and used for reducing the air pressure inside the hose, and a controller for controlling the switch of the pressure relief pipe is arranged on the pressure relief pipe.
[0025] By adopting the above technical solution, when the pressure detector detects that the pressure value inside the hose exceeds the safety value, the controller is started to discharge the gas inside the hose through the pressure relief pipe.
[0026] In summary, the present application includes at least one of the following beneficial technical effects:
[0027] 1. By inserting the hose into the pipeline, wrapping the tying bag around the end of the hose, fixedly installing one end of the tying bag close to the pipeline on the pipeline, tying the tying bag and the end of the hose far from the pipeline to the support member through a tying member, and inflating the hose with inflation gas through an air inlet pipe, the hose expands, and the hose outside the pipeline expands and abuts against the tying bag after expansion. The end of the hose is tightly supported by the tying bag, reducing the probability of excessive expansion between the hose and the tying part.

[0035] The following further elaborates on the present application in conjunction with the attached Figures 1-5 drawings.
[0036] The embodiments of the present application disclose a hose binding structure.
[0037] Embodiment 1
[0038] Referring to Figure 1 and Figure 2 , a hose binding structure includes a head bag 3 provided on the pipeline 1 and supporting the outer side wall of the hose 2. A support member 4 for inflating the inside of the hose 2 and blocking the end face of the hose 2 is provided inside the hose 2. A binding member for binding the head bag 3 and the hose 2 to the support block is provided on the head bag 3.
[0039] Referring to Figure 1 and Figure 2 , the head bag 3 has a cylindrical structure. The head bag 3 is located outside the hose 2. One side of the head bag 3 close to the pipeline 1 extends into the pipeline 1. When the hose 2 expands, the head bag 3 located in the pipeline 1 is pressed against the inner side wall of the pipeline 1, thereby fixing the head bag 3 on the pipeline 1.
[0040] Referring to Figure 1 and Figure 2 , the head bag 3 is made of a breathable material, so that when the hose 2 expands, the air between the hose 2 and the head bag 3 is discharged, and then the hose 2 is pressed against the inner side wall of the head bag 3. Furthermore, the head bag 3 tightly supports the hose 2 to prevent the hose 2 from being damaged due to excessive expansion.
[0041] Referring to Figure 2 and Figure 3 , the support member 4 has a cylindrical structure. The support member 4 is located inside the hose 2 at one end away from the pipeline 1. Multiple groups of anti-slip convex rings 44 are fixedly installed on the outer side wall of the support member 4. One end of the convex ring 44 close to the pipeline 1 is inclined.
[0042] Referring to Figure 3, when in use, insert the support member 4 into the hose 2. The inclined surface of the convex ring 44 facilitates the insertion of the support member 4 into the interior of the hose 2. After the support member 4 is completely inserted into the hose 2, wrap the end of the tie bag 3 away from the pipe 1 around the hose 2 and press it tightly against the support member 4. Then, use the binding member on the outer side of the tie bag 3 to bind the tie bag 3 and the hose 2 to the support member 4. At the same time, the binding member presses part of the hose 2 and the tie bag 3 into the gap between two adjacent convex rings 44, thereby improving the fixing effect of the tie bag 3, the hose 2, and the support member 4, and reducing the probability of mutual sliding between the hose 2 and the tie bag 3 and the support member 4 during use; in this embodiment, the binding member is a binding band.
[0043] Refer to Figure 2 and Figure 3 , after the binding member binds the tie bag 3 and the hose 2 tightly to the support member 4, the end surface of the hose 2 is sealed. An air inlet pipe 41 is fixedly installed on the support member 4. The air inlet pipe 41 passes through the support member 4 and communicates with the interior of the hose 2. The air inlet pipe 41 is used to supply expansion gas to the interior of the hose 2, so that the hose 2 expands under the action of gas pressure and presses against the inner wall of the pipe 1. During the expansion process, the tie bag 3 presses against and supports the end of the hose 2, reducing the probability of excessive expansion of the hose 2.
[0044] Refer to Figure 3 , a pressure detector 42 is also fixedly installed on the support member 4. The pressure detector 42 communicates with the interior of the hose 2. The pressure detector 42 is used to detect the magnitude of the air pressure value inside the hose 2, so as to facilitate real-time monitoring of the air pressure data inside the hose 2; at the same time, a pressure relief pipe 43 is also fixedly installed on the support member 4. The pressure relief pipe 43 communicates with the interior of the hose 2. A controller is also fixedly installed on the pressure relief pipe 43. When the pressure detector 42 detects that the air pressure value inside the hose 2 is too large, turn on the controller, and discharge the expansion gas inside the hose 2 through the pressure relief pipe 43 until the air pressure value inside the hose 2 returns to the safe value range.
[0045] The working principle of Embodiment 1 of this application is as follows:
[0046] Insert the hose 2 into the pipe 1, wrap the tie bag 3 around the end of the hose 2, fixedly install the end of the tie bag 3 close to the pipe 1 on the pipe 1, use the binding member to bind the end of the tie bag 3 and the hose 2 away from the pipe 1 to the support member 4, and introduce expansion gas into the hose 2 through the air inlet pipe 41, so that the hose 2 expands. The hose 2 located outside the pipe 1 expands and presses against the tie bag 3 after expansion. The tie bag 3 presses against and supports the end of the hose 2, reducing the probability of excessive expansion between the hose 2 and the binding location.
[0047] Embodiment 2
[0048] Refer to Figure 4 and Figure 5, the difference between this embodiment and Embodiment 1 is that the tie bag 3 is detachably arranged on the pipeline 1 through the fixing component 5. The fixing component 5 includes a first flange 51, a second flange 52 and fixing bolts 53. The first flange 51 is fixedly installed on the end face of the pipeline 1. The first flange 51 is coaxially installed with the pipeline 1, and the inner diameter of the first flange 51 is equal to the inner diameter of the pipeline 1; the second flange 52 is symmetrical with the first flange 51, and the second flange 52 is cooperatively locked with the first flange 51. One end of the tie bag 3 close to the pipeline 1 is wrapped around the second flange 52; there are multiple groups of fixing bolts 53, and the multiple groups of fixing bolts 53 are arranged on the second flange 52 and are used to lock the second flange 52 on the first flange 51.
[0049] Refer to Figure 4 and Figure 5 , specifically, when the second flange 52 is pressed against the first flange 51, the tie bag 3 is pressed against the end face of the first flange 51. The fixing bolts 53 are sequentially passed through the second flange 52, the tie bag 3 and the second flange 52 and locked by fixing nuts, so as to detachably install the tie bag 3 on the pipeline 1.
[0050] The working principle of Embodiment 2 of this application is as follows:
[0051] One end of the tie bag 3 close to the pipeline 1 is fixedly installed on the second flange 52, and the second flange 52 is detachably installed on the first flange 51 through the fixing bolts 53 and the fixing nuts, so as to detachably install the tie bag 3 on the pipeline 1.
[0052] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
