Description

Technical Field

[0001] The present application relates to the technical field of pipeline repair, and particularly to a hose inflation device. 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 restores or improves the function and service life of the pipeline by installing a new lining inside the existing pipeline.

[0003] During pipeline repair, first, the repair hose needs to be pulled into the pipeline to be repaired, then the lamp holder is placed into the hose, then both ends of the hose are tied, and then gas needs to be filled into the hose for pressurization so that the hose presses against the pipe body, and then the lamp holder moves for curing.

[0004] However, the lamp holder needs to be powered by an electric wire, and when inflating the inside of the hose, it also needs to be connected to the inside of the hose. Since the connection can only be made through the tied part, the passing of the electric wire and inflation will interfere with the tied part, thus reducing the efficiency of pipeline repair. Summary of the Utility Model

[0005] In order to reduce the probability of interference between the electric wire and inflation and the tied part and improve the efficiency of pipeline repair, the present application provides a hose inflation device.

[0006] A hose inflation device provided by the present application adopts the following technical solution:

[0007] A hose inflation device includes a support member provided at the end of the hose and sealing the end of the hose. The support member extends into the hose and is fixed by a tying member. The support member includes:

[0008] A housing, which is provided at the end of the hose and is hermetically connected to the hose by a tying member;

[0009] A sealing assembly, which is provided on the end face of the housing away from the hose and seals the end face of the housing. The sealing assembly allows the electric wire to slide along the axis of the hose;

[0010] An air intake assembly, which is provided on the side wall of the housing and is connected to the inside of the hose. The air intake assembly is used to control the air pressure value inside the hose.

[0011] By adopting the above technical solution, the housing is inserted into the hose and fixed by a binding member. Gas is introduced into the hose through the air inlet assembly to make the hose closely adhere to the inner side wall of the pipeline. The lamp holder is placed into the hose, and the end face of the hose is sealed by the sealing assembly. At the same time, the electric wire slides within the sealing assembly, separating the electric wire, the air inlet assembly, and the binding part from each other, reducing the probability of interference between the electric wire and the inflation and binding part, and improving the pipeline repair efficiency.

[0012] Further, a feed port for facilitating the placement of the lamp holder into the hose is provided on the end face of the housing away from the hose. The sealing assembly includes:

[0013] A sealing cover that is slidably arranged on the feed port to seal the feed port. A sliding hole for facilitating the sliding of the electric wire to pass through is provided at the center of the sealing cover;

[0014] A locking ring that is arranged on the end face of the sealing cover and abuts against the end face of the housing;

[0015] A locking bolt that is arranged on the locking ring and locks the locking ring on the housing.

[0016] By adopting the above technical solution, the sealing cover is slidably installed on the feed port, the locking ring abuts against the end face of the housing, and then is locked on the housing by the locking bolt to seal the feed port. At the same time, the sliding hole facilitates the sliding of the electric wire to pass through.

[0017] Further, a sealing convex ring is coaxially arranged on the inner side wall of the sliding hole, and the sealing convex ring abuts against the side wall of the electric wire.

[0018] By adopting the above technical solution, the sealing convex ring facilitates the sealing of the gap between the electric wire and the sliding hole. At the same time, the contact area between the sealing cover and the electric wire is reduced by the sealing convex ring, facilitating the sliding of the electric wire within the sliding hole.

[0019] Further, the sealing convex ring is made of flexible rubber material.

[0020] By adopting the above technical solution, the sealing convex ring made of flexible rubber material has a certain amount of deformation. When a force is applied to the electric wire, the sealing convex ring deforms, facilitating the sliding of the electric wire to pass through. When no force is applied to the electric wire, the sealing convex ring returns to its original position, improving the sealing effect.

[0021] Further, the sealing cover is composed of two symmetrically arranged sealing bodies spliced together, and the sealing body is a semi-cylindrical structure.

[0022] By adopting the above technical solution, the electric wire is placed on the sealing body, then the other group of sealing bodies is abutted against the first group of sealing bodies, and then the assembled sealing cover is installed on the housing to install the electric wire in the sliding hole.

[0023] Furthermore, the air intake assembly includes:

[0024] An intake pipe, which is arranged on the side wall of the housing and is internally communicated with the hose. The intake pipe is communicated with a gas supply device and is used for supplying gas into the hose;

[0025] A pressure detector, which is arranged on the housing and is used for detecting the air pressure value inside the hose;

[0026] A pressure relief pipe, which is arranged on the housing and is used for discharging the gas inside the hose out of the hose;

[0027] A control valve, which is arranged on the pressure relief pipe and is electrically connected to the pressure detector and is used for opening the pressure relief pipe when the pressure value inside the hose is too large

[0028] By adopting the above technical solution, the gas supply device passes expansion gas into the hose through the intake pipe, so that the hose is closely attached to the inner side wall of the pipeline. When the pressure detector detects that the pressure value inside the hose is greater than the safety value, the control valve is started, and the gas inside the hose is discharged through the pressure relief pipe, so as to control the air pressure value inside the hose.

[0029] Furthermore, a sealing ring is arranged on the side of the housing close to the locking ring, and the locking ring presses the sealing ring against the housing for sealing.

[0030] By adopting the above technical solution, the sealing ring presses the sealing ring against the housing, so as to improve the sealing effect between the sealing ring and the housing, and further improve the sealing effect between the sealing cover and the housing.

[0031] Furthermore, a plurality of groups of locking convex rings are arranged at intervals on the outer side wall of the housing close to one end of the hose, and an inclined surface is arranged at one end of the locking convex ring close to the hose.

[0032] By adopting the above technical solution, first the hose is pulled into the pipeline. Through the guidance of the inclined surface of the locking convex ring, it is convenient for the housing to extend into the hose. Finally, the hose is tied to the housing through a tying member. The probability of the hose slipping on the housing is reduced by a plurality of groups of locking convex rings.

[0033] In summary, the present application includes at least one of the following beneficial technical effects:

[0034] 1. By extending the housing into the hose and fixing it through a tying member, passing gas into the hose through the intake pipe and making the hose closely attached to the inner side wall of the pipeline, putting the lamp holder into the hose through the feed port, slidingly installing the wire on the sealing cover, and the sealing cover sealing the feed port, so that the wire, the intake pipe and the tying part are separated from each other, reducing the probability of interference between the wire and the inflation and the tying part, and improving the pipeline repair efficiency.

[0035] 2. By inserting the lamp holder through the feeding port into the hose and enabling the two sets of sealing bodies to be mutually connectable and matched, the electric wire can be quickly placed into the sliding hole, and then the combined sealing cover is locked on the housing through the locking bolts, thereby sealing one end of the hose and ultimately improving the installation efficiency of the electric wire of the lamp holder.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0042] The following further describes the present application in detail with reference to the attached Figures 1-5 drawings.

[0043] The embodiment of the present application discloses a hose inflation device.

[0044] Embodiment 1

[0045] Referring to Figure 1 , a hose inflation device includes a support member 3 provided at the end of the hose 2 and sealing the end of the hose 2, and the support member 3 extends into the hose 2 and is fixedly bound by a binding member 6.

[0046] Referring to Figure 1 and Figure 2, the support member 3 includes a housing 31, a sealing assembly 4 and an air intake assembly 5. One end of the housing 31 close to the hose 2 is a cylindrical structure. Multiple groups of locking rings 311 are installed at intervals on the outer side wall of the end of the housing 31 close to the hose 2. An inclined surface is provided at one end of the locking ring 311 close to the hose 2. During installation, first pull the hose 2 into the pipeline 1, then insert the housing 31 into the hose 2. Through the guidance of the inclined surface of the locking ring 311, it is convenient for the housing 31 to extend into the hose 2. Finally, tie the hose 2 to the housing 31 through a binding member 6. The probability of the hose 2 slipping on the housing 31 is reduced by multiple groups of locking rings 311.

[0047] Refer to Figure 1 and Figure 2 , the sealing assembly 4 is arranged on the end face of the housing 31 far from the hose 2. The sealing assembly 4 is used to seal the end face of the housing 31. The sealing assembly 4 allows the wire 7 to slide along the axis direction of the hose 2. The side of the housing 31 far from the hose 2 is a cylindrical structure, so as to facilitate the sealing of the side of the housing 31 far from the hose 2. At the same time, a feed port 312 is provided on the cylindrical housing 31, and the feed port 312 is convenient for putting the lamp holder into the hose 2 from the housing 31.

[0048] Refer to Figure 2 and Figure 3 , the sealing assembly 4 includes a sealing cover 41, a locking ring 42 and a locking bolt 43. The sealing cover 41 is slidably installed on the feed port 312. The sealing cover 41 is used to seal the feed port 312. A sliding hole 411 for the wire 7 to pass through is provided at the center of the sealing cover 41. The diameter of the sliding hole 411 is larger than the diameter of the wire 7. A sealing convex ring 412 is coaxially and fixedly installed on the inner side wall of the sliding hole 411. The inner side wall of the sealing convex ring 412 abuts against the side wall of the wire 7. The sealing convex ring 412 is convenient for sealing the gap between the wire 7 and the sliding hole 411. At the same time, the contact area between the sealing cover 41 and the wire 7 is reduced by the sealing convex ring 412, thereby facilitating the sliding of the wire 7 in the sliding hole 411. In order to improve the sealing effect of the sealing convex ring 412 on the wire 7, the sealing convex ring 412 is made of flexible rubber material.

[0049] Refer to Figure 1 and Figure 2, the locking ring 42 is fixedly installed at one end of the sealing cover 41 away from the hose 2. The locking ring 42 and the sealing cover 41 are of an integrally formed structure. An installation groove for placing the locking ring 42 is provided on the housing 31. The inner side wall of the locking ring 42 abuts and seals against the outer side wall of the sealing cover 41, and the end face of the locking ring 42 abuts in the installation groove. In order to improve the sealing effect between the locking ring 42 and the housing 31, a sealing ring groove coaxial with the locking ring 42 is provided on the housing 31, and a sealing ring is fixedly installed in the sealing ring groove. During installation, the locking ring 42 is abutted against the sealing ring to improve the sealing effect between the sealing ring and the housing 31; the locking bolt 43 passes through the locking ring 42 and is locked on the housing 31. The locking bolt 43 is located outside the sealing ring, and finally the sealing cover 41 is hermetically locked on the housing 31.

[0050] Refer to Figure 1 , the air intake assembly 5 is arranged on the side wall of the housing 31 and is internally communicated with the hose 2. The air intake assembly 5 is used to control the air pressure value in the hose 2. The air intake assembly 5 includes an intake pipe 51, a pressure detector 52, a pressure relief pipe 53 and a control valve 54. The intake pipe 51 is fixedly installed on the side wall of the housing 31. One end of the intake pipe 51 is internally communicated with the hose 2, and the other end of the intake pipe 51 is communicated with a gas supply device. The gas supply device supplies expansion gas to the hose 2 through the intake pipe 51; the pressure detector 52 is fixedly installed on the side wall of the housing 31. The pressure detector 52 is internally communicated with the hose 2. The pressure detector 52 is used to detect the air pressure value in the hose 2; the pressure relief pipe 53 is fixedly installed on the side wall of the housing 31. The pressure relief pipe 53 is used to discharge the gas in the hose 2 to reduce the air pressure value in the hose 2; the control valve 54 is fixedly installed on the pressure relief pipe 53. The control valve 54 is electrically connected to the pressure detector 52 and is used to open or close the pressure relief pipe 53; when the pressure detector 52 detects that the pressure value in the hose 2 is greater than the safety value, the control valve 54 is opened to relieve the pressure of the hose 2; when the pressure detector 52 detects that the pressure value in the hose 2 is less than the safety value, the control valve 54 is closed to close the pressure relief pipe 53.

[0051] Refer to Figure 1 , Figure 2 and Figure 3 , during use, the housing 31 is inserted into the hose 2 and fixed by a binding band. Then the lamp holder is put into the hose 2 from the feed port 312. The wire 7 of the lamp holder passes through the sliding hole 411. The sealing convex ring 412 improves the sealing performance between the sealing cover 41 and the wire 7. Then the sealing cover 41 is locked on the housing 31 by the locking bolt 43, which facilitates the sliding of the wire 7 on the sealing cover 41 when the lamp holder moves in the hose 2. At the same time, expansion gas is introduced into the hose 2 through the intake pipe 51, so that the hose 2 is closely attached to the inner side wall of the pipeline 1, separating the intake pipe 51, the wire 7 and the binding part from each other, reducing the probability of interference between the wire 7 and the inflation and binding parts, and improving the repair efficiency of the pipeline 1.

[0052] The working principle of Embodiment 1 of this application is as follows:

[0053] Insert the housing 31 into the hose 2 and fix it by the binding member 6. Pass gas into the hose 2 through the air inlet pipe 51 to make the hose 2 closely adhere to the inner side wall of the pipeline 1. Put the lamp holder into the hose 2 through the feed port 312. The wire 7 is slidably installed on the sealing cover 41, and the sealing cover 41 seals the feed port 312, so that the wire 7, the air inlet pipe 51 and the binding part are separated from each other, reducing the probability of interference between the wire 7 and the inflation and binding part, and improving the repair efficiency of the pipeline 1.

[0054] Embodiment 2

[0055] Referring to Figure 4 and Figure 5 The difference between this embodiment and Embodiment 1 is that in order to facilitate the installation of the wire 7 of the lamp holder on the sealing cover 41, the sealing cover 41 is spliced by two groups of symmetric sealing bodies 8. The sealing body 8 is a semi-cylindrical structure, and the sliding hole 411 is located at the connection of the two sealing bodies 8.

[0056] Referring to Figure 4 and Figure 5 During use, insert the lamp holder into the hose 2, put the wire 7 on the sliding hole 411 of one group of sealing bodies 8, and then cover the second group of sealing bodies 8 on the first group of sealing bodies 8 to put the wire 7 into the sliding hole 411. In order to improve the sealing effect of the two groups of sealing bodies 8, positioning blocks and positioning grooves that cooperate with each other are respectively fixedly installed on the two groups of sealing bodies 8, so as to facilitate the two groups of sealing bodies 8 to form the sealing cover 41 and seal the feed port 312.

[0057] The working principle of Embodiment 2 of this application is as follows:

[0058] Pass the lamp holder through the feed port 312 and into the hose 2. Through the mutual engagement of the two groups of sealing bodies 8, the wire 7 can be quickly put into the sliding hole 411, and then the combined sealing cover 41 is locked on the housing 31 by the locking bolt 43 to seal one end of the hose 2, ultimately improving the installation efficiency of the wire 7 of the lamp holder.

[0059] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this.
