[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on July 24, 2023, with application number 202310907526.7 and invention name “A lined hose flipping machine and its use method”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of pipeline repair, and in particular to a liner hose turning machine and a method for using the same. Background Art

[0003] The lining hose flipping machine is a commonly used device for trenchless pipe repair. Its working principle is to use the thrust of the pressure medium to flip the hose coated with adhesive or curing resin along the inner wall of the damaged pipe, expand it, and finally solidify it to form a new lining pipe.

[0004] Current lined hose turning machines are generally designed for medium and large-sized pipelines, such as municipal underground pipelines, such as the Chinese patent with authorization announcement number CN207279137U. Traditional lined hose turning machines occupy a large area as a whole and have high requirements for the selection of construction sites. Therefore, they have the problem of poor flexibility and maneuverability. For example, they cannot be applied to the repair of pipelines such as water pipes and gas pipes in residential areas. At the same time, most of them also have the problem of slow hose turning speed, which can easily lead to repair failure due to missing the curing time during construction. In summary, how to improve the lined hose turning machine to improve its flexibility and maneuverability and obtain a higher hose turning speed has become a technical problem that needs to be solved urgently by those skilled in the art.

[0039] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] Referring to Figures 1 to 10, an embodiment of the present application provides a liner hose turning machine, comprising a launch tube 1, a first support 2, a second support 4, and a locking member 5, wherein the launch tube 1 comprises a tube body and a tube head 13, wherein the tube body is provided with a hose inlet at one end away from the tube head 13, the tube head 13 is a conical tube and is provided with a hose outlet at one end away from the tube body, the hose outlet is located at the smaller end of the tube head 13 and has a flange-shaped baffle 131, the baffle 131 is used to cooperate with a tightening member to fix the turning mouth of the hose, and the larger end of the tube head 13 is detachably connected to the tube body. The first support 2 is fixedly connected to the tube body, that is, the tube body is fixedly mounted on the first support 2, the second support 4 is rotatably connected to the first support 2, the bottom of the second support 4 is provided with at least three retractable legs 3, and the locking member 5 is used to fix the first support 2 and the second support 4 so as to rotate to a target position relative to the second support 4. It is easy to understand that the first support 2 is located on the other side of the second support 4 relative to the support leg 3 , that is, the first support 2 is connected to the upper part and / or side of the second support 4 .

[0041] Because the tube head 13 is detachably connected to the tube body, a set of launch tubes can be equipped with tube heads 13 of various sizes during use. For example, a DN200 tube body can be equipped with tube heads 13 of any size, ranging from DN50 to DN200, enabling the turning and repair of pipes of various diameters without having to replace the main equipment, greatly saving construction costs. During operation, the lining hose turning machine stands on the construction site via the legs 3. Workers can adjust each leg 3 to the appropriate length according to the space conditions on site. Moreover, based on the rotational connection between the second support 4 and the first support 2, workers can easily adjust the launch tube 1 to the appropriate angle to align the tube head 13 with the pipe opening to be repaired. The various angles of the launch tube 1 are suitable for vertical insertion repair, repair of pipes with turning angles, and repair of pipes in special situations. As can be seen, the lining hose turning machine provided by this application is highly flexible and maneuverable to adapt to different site conditions, and can conveniently carry out pipeline repair work even in sites with limited space, such as residential areas. In a preferred embodiment, the top of the leg 3 is rotatably connected to the bottom of the second support 4, so that the leg 3 can not only adjust the length, but also be extended and retracted relative to the second support 4 like an umbrella rib, so as to better adapt to various different site conditions.

[0042] The launch tube 1 is used to connect to an air source device (such as the air compressor 100 described later). After the air source device passes gas into the launch tube 1, the hose flips and moves forward under the action of the air pressure. In the previous preparation stage, one end of the hose must first be passed through the launch tube 1 from the hose outlet, and after passing through the hose outlet, this end must be pulled onto the baffle 131, that is, the hose mouth is turned outward to form a socket connection with the smaller end of the tube head 13, and then the hose is tightened on the tube head 13 with a tightening piece. Since the tube head 13 is a conical tube and is provided with a baffle 131 that cooperates with the tightening piece, the air pressure that pushes the hose to flip forward during construction can be set to a higher value. Under the constraint of the tube head 13, the airflow rushes towards the hose more concentratedly, and the baffle 131 ensures the reliability of the connection between the hose and the tube head 13. Therefore, the liner hose flipping machine provided in this application can achieve a higher hose flipping speed.

[0043] Specifically, the tightening member can be a clamp or a cable tie, and the locking member 5 can be a positioning pin. In order to cooperate with the positioning pin to lock the relative position of the first support 2 and the second support 4, positioning holes for inserting the positioning pins need to be provided on the first support 2 and the second support 4. The rotational connection between the first support 2 and the second support 4 can be a pivot connection or a ball joint connection. As shown in Figure 1, in this embodiment, the first support 2 and the second support 4 are connected by a horizontal rotation axis 6, that is, the first support 2 can rotate in a vertical plane relative to the second support 4. In a preferred embodiment, the second support 4 includes a base and a rotating chassis connected by a vertical rotation axis, that is, the rotating chassis can rotate in a horizontal plane relative to the base, the top of the support leg 3 is connected to the base, and the first support 2 is rotationally connected to the rotating chassis. In this way, the staff can adjust the launch tube 1 to the desired angle more quickly.

[0044] As shown in Figures 3, 4 and 8, in this embodiment, the first support 2 includes a support plate 21 with a through hole 211 in the middle. The support plate 21 is provided with a plurality of first mounting holes 212 distributed around the through hole 211. The barrel includes a first barrel 11 and a second barrel 12 located on both sides of the support plate 21. The first barrel 11 is provided with a first flange at one end close to the support plate 21, and the second barrel 12 is provided with a second flange at one end close to the support plate 21. The first flange and the second flange are fixedly connected by bolts passing through the first mounting holes 212. By providing the support plate 21, a relatively secure fixed connection between the barrel and the first support 2 can be achieved. Moreover, the bolts for connecting the first flange and the second flange are preferably long bolts. As shown in Figure 4, these bolts can be provided with elastic members for pre-tightening, thereby improving the reliability of the connection.

[0045] As shown in Figures 3 to 5, the first cylinder 11 is located on the side of the support plate 21 away from the cylinder head 13. An airbag ring 113 is provided in the first cylinder 11. The outer surface of the first cylinder 11 is provided with a first air supply connector 111 that is connected to the airbag ring 113. The outer surface of the second cylinder 12 is provided with a second air supply connector 121 that is connected to the inner cavity of the second cylinder 12. In this embodiment, the first cylinder 11 and the second cylinder 12 are respectively provided with the first air supply connector 111 and the second air supply connector 121. This makes it easy to distinguish different air supply connectors when connecting pipelines to avoid incorrect connections. The length of the first cylinder 11 can be set according to the width of the airbag ring 113 and generally does not need to be made too long. The first air supply connector 111 is used to supply air to the airbag ring 113. After the gas is filled into the airbag ring 113, its volume expands, thereby pressing the hose passing through the airbag ring 113 to form a seal. In this way, the expanded airbag ring 113, the second cylinder 12 and the cylinder head 13 together form a pressure chamber. The second air supply connector 121 is used to supply air to the pressure chamber. The gas is continuously filled into the pressure chamber, causing the hose to flip forward under the action of the air pressure.

[0046] In this embodiment, the liner hose turning machine includes a first safety valve 81 and a second safety valve 82 fixedly mounted on a support plate 21. The outer surface of the first cylinder 11 is provided with a first safety valve connector 112 connected to the airbag ring 113, and the first safety valve 81 is connected to the first safety valve connector 112 through a pipeline; the outer surface of the second cylinder 12 is provided with a second safety valve connector 122 connected to the inner cavity of the second cylinder 12, and the second safety valve 82 is connected to the second safety valve connector 122 through a pipeline. The support plate 21 not only serves to connect and support the first cylinder 11 and the second cylinder 12, but also serves to support the safety valve, so that the various safety valves are arranged together as much as possible, which is convenient for subsequent unified maintenance. Moreover, the safety valve is arranged on the support plate 21, which can avoid being directly installed on the cylinder body, which will cause the cylinder structure to be complicated, which is conducive to reducing the difficulty of manufacturing the cylinder. Preferably, the air supply joint and the safety valve joint are arranged 90° apart along the circumference of the barrel. As can be seen from the top views shown in Figures 4 and 5, in the present embodiment, the first air supply joint 111 and the second air supply joint 121 are both arranged at the top of the barrel, and the first safety valve joint 112 and the second safety valve joint 122 are respectively arranged on both sides of the barrel. Of course, in other embodiments, the angular distance between the air supply joint and the safety valve joint along the circumference of the barrel can be set to other values, for example, can be set to 45° or 60° apart. As shown in Figure 8, in order to realize the installation of the safety valve on the support plate 21, the support plate 21 can be provided with a safety valve reserved hole 214.

[0047] As shown in Figures 1 and 3, in this embodiment, the liner hose flipping machine includes an end plate detachably connected to the end of the first cylinder 11 away from the support plate 21, and the end plate includes a first plate body 141 with a first notch and a second plate body 142 with a second notch, and the first notch and the second notch are put together to form a flat mouth. After the hose passes through the airbag ring 113, the first plate body 141 and the second plate body 142 are installed up and down at the end of the first cylinder 11, so that the first notch and the second notch form a horizontal flat mouth. The end plate formed by the first plate body 141 and the second plate body 142 can limit the excessive expansion and deformation of the airbag ring 113. When the hose continues to move forward, the flat mouth plays the role of preliminarily flattening the hose. The hose is double-flattened by the flat mouth and the airbag ring 113, which can further ensure that the flipped hose is wrinkle-free and has a regular shape.

[0048] As shown in Figures 1, 3, 5, 6 and 9, in this embodiment, the first support 2 includes two T-shaped side plates 22 arranged on two sides of the support plate 21. The T-shaped head of the T-shaped side plate 22 is located at the end of the T-shaped side plate 22 away from the second support 4. The T-shaped head is connected to a control console 7 supported by the two T-shaped side plates 22. The control console 7 is provided with a first pressure gauge 71, a second pressure gauge 72, a first pressure regulating switch 74 and a second pressure regulating switch 75. The first pressure gauge 71 and the first pressure regulating switch 74 are connected to the first air supply connector 111 through a first air supply pipeline, and the second pressure gauge 72 and the second pressure regulating switch 75 are connected to the second air supply connector 121 through a second air supply pipeline. In this embodiment, the heads of the two T-shaped side plates 22 arranged opposite to each other are used to form a structure supporting the control console 7, which can make the overall structure of the liner hose turning machine simpler and more compact, and is conducive to better miniaturization and lightweighting of the entire machine. As shown in Figures 8 and 9, in order to achieve the connection between the support plate 21 and the T-shaped side plate 22, a second mounting hole 213 for mounting the T-shaped side plate 22 is opened on the side of the support plate 21, and a third mounting hole 225 corresponding to the second mounting hole 213 is opened on the side of the T-shaped side plate 22.

[0049] As shown in Figures 1, 2, 9 and 10, in this embodiment, in order to realize the rotational connection between the first support 2 and the second support 4, the second support 4 includes a chassis 41 with semicircular side plates on both sides. A first rotation center hole 411 for passing the horizontal rotation axis 6 is opened at the center of the side plate. Moreover, the side plate is provided with a plurality of first positioning holes 412 arranged along an arc line. The arc line where the first positioning holes 412 are located is coaxial with the first rotation center hole 411. The T-shaped side plate 22 is provided with a second rotation center hole 221 and a second positioning hole 222. The second rotation center hole 221 is aligned with the first rotation center hole 411 for passing the horizontal rotation axis 6. When the first support 2 rotates relative to the second support 4 around this horizontal rotation axis 6, the second positioning hole 222 can pass through the position of each first positioning hole 412. The first support 2 can be locked in the current position by inserting the positioning pins into the first positioning holes 412 and the second positioning holes 222. Pulling out the positioning pins can release the restriction on the first support 2 so that the first support 2 can be rotated to other positions. The angular spacing between the first positioning holes 412 and the central angle of the arc line corresponding to the first positioning holes 412 can be flexibly set as needed. In this embodiment, the central angle of the arc line corresponding to the first positioning holes 412 is 180°, and the first positioning holes 412 are arranged in sequence at an angular spacing of 22.5°. In a preferred embodiment, the chassis 41 is further provided with a vertical rotation axis connection hole 413. The second support 4 includes a base connected to the chassis 41 via a vertical rotation axis. This vertical rotation axis is provided through the vertical rotation axis connection hole 413, allowing the chassis 41 to rotate relative to the base in a horizontal plane. In this way, the staff can more quickly adjust the launch tube 1 to the desired angle.

[0050] Specifically, the same air source can be used to supply air to the airbag ring 113 and the pressure chamber. For example, in this embodiment, the console 7 is equipped with a total air pressure gauge 73 and a total pressure regulating switch 76. The T-shaped head of either T-shaped side panel 22 is equipped with a total air inlet port 9 for connecting to the air compressor 100. This means that the total air inlet port 9 can be installed on either of the two T-shaped side panels 22, that is, the T-shaped head of one T-shaped side panel 22 can be equipped with the total air inlet port 9. The total air pressure gauge 73 and the total pressure regulating switch 76 are connected to the total air inlet port 9 via a total air supply line. The total pressure regulating switch 76 is connected to the first pressure regulating switch 74 and the second pressure regulating switch 75 via two branch lines, respectively. The T-shaped side panel 22 not only supports the console 7, but also supports the total air inlet port 9. As shown in Figure 5, during the equipment preparation phase, personnel connect the air compressor 100 and other air source equipment through the total air inlet port 9. As shown in FIG. 9 , in order to install the main air inlet interface 9 on the T-shaped side plate 22 , the T-shaped side plate 22 may be provided with an air inlet interface reserved hole 223 .

[0051] In a preferred embodiment, the console 7 is pivotally connected to the T-shaped side panel 22, allowing the console 7 to switch between at least two positions: a horizontally folded position and a vertically upright position. As shown in Figures 2 and 9, in this embodiment, the end of the console 7, distal from the barrel head 13, is connected to the T-shaped side panel 22 via a pivot axis. The T-shaped head of the T-shaped side panel 22 defines a third rotational center hole 224 for receiving this pivot axis. The operator can adjust the angle between the console 7 and the T-shaped head of the T-shaped side panel 22 to any value within a range of 0° to 90°. For example, the operator can erect the console 7, i.e., form a 90° angle between the console 7 and the T-shaped head of the T-shaped side panel 22, to better observe the pressure gauge reading and operate the pressure regulating switch on the console 7. When reading the barometer and operating the pressure regulating switch are not required, the console 7 is maintained in a horizontally folded position, i.e., at a 0° angle between the console 7 and the T-shaped head of the T-shaped side panel 22.

[0052] As shown in Figures 6 and 7 , in this embodiment, a roller gauge 123 is installed within the second barrel 12 for contacting the hose, and the control console 7 is equipped with an electronic screen 77 for displaying the measurement data from the roller gauge 123. The roller gauge 123 contacts the hose, and as the hose advances, it drives the roller of the roller gauge 123 to rotate, thereby detecting the hose's speed. The control console 7 can be equipped with a timer and a computing unit to calculate the total length of the hose ejected (i.e., the length of the hose flipped) using the hose's speed detected by the roller gauge 123 and display it in real time on the electronic screen 77. Furthermore, other data such as the pressure within the airbag ring 113 and the pressure within the second barrel 12 can also be displayed on the electronic screen 77. This allows operators to fully monitor the pressure, flipping speed, and flipped length during the flipping process through the control console 7, allowing them to adjust the parameters as needed. Precise flipping can be achieved by controlling only one parameter, pressure, for convenient operation. Of course, the electronic screen 77 can also be used to display more information. For example, equipment failure information can be displayed on the electronic screen 77 so that the staff can find the root cause of the failure more quickly and eliminate the failure as soon as possible.

[0053] In this manual, the structure of each part is described in a progressive manner, and the structure of each part focuses on the differences from the existing structure. The overall and partial structures of the lined hose turning machine can be obtained by combining the structures of the above multiple parts.

[0054] Based on the liner hose turning machine provided in this application, this application also provides a method for using the liner hose turning machine, which method includes the following steps:

[0055] S1, taking a barrel head 13 of appropriate specifications according to the size of the pipe opening of the pipeline to be repaired, and installing the barrel head 13 on the barrel body.

[0056] S2, stand the support legs 3 at the construction site and adjust the length of the support legs 3 so that the launch tube 1 is located near the pipe mouth of the pipeline to be repaired.
