Description

Technical Field

[0001] This application relates to the field of pipeline repair equipment technology, and in particular to a pipeline lining airbag production device. Background Technology

[0002] In the field of modern pipeline repair and maintenance, pipeline lining airbags are an important tool widely used in trenchless pipeline repair projects. Their main function is to support and pressurize the lining material during pipeline repair, ensuring a tight fit against the pipeline wall, thereby repairing the pipeline and restoring its normal function. However, the production process of pipeline lining airbags presents some challenges. Traditional production equipment struggles to guarantee the uniformity and tightness of the winding process. Due to the lack of effective auxiliary winding mechanisms, unevenness and inconsistent tension on the airbag surface can easily occur during winding. This not only affects the quality and performance of the airbag but may also lead to localized excessive or insufficient pressure during actual use, reducing the airbag's lifespan and repair effectiveness.

[0003] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: existing devices may lack built-in pressure sensors to monitor the pressure on the airbag in real time, and cannot automatically adjust the height or pressure of related components based on pressure data. It is difficult to quickly and accurately adjust the position of the liner airbag according to different specifications or shapes. This limits the applicability of the device, and it may not be able to effectively complete the winding task for the production of some special-sized or shaped airbags. Utility Model Content

[0004] In order to solve the problems mentioned in the background art, this application provides a pipeline lining airbag production apparatus.

[0005] This application provides a pipeline lining airbag production device, which adopts the following technical solution: A pipeline lining airbag production device includes a base plate, an auxiliary winding assembly is provided on the top of the base plate, and an lining airbag body is provided on one side of the auxiliary winding assembly.

[0006] An auxiliary winding assembly includes a driven rotating shaft, a pressure detection sleeve, a positioning plate, arc-shaped side rods, and pressure rollers. The driven rotating shaft is movably mounted on the left and right sides of the inner liner airbag body. A pressure detection sleeve is fixedly sleeved on one side of the driven rotating shaft. The positioning plate is positioned directly above the inner liner airbag body. An arc-shaped side rod is fixedly mounted on the bottom of the positioning plate, and the arc-shaped side rods are symmetrically arranged with the inner liner airbag body as the center. A pressure roller is movably mounted on one side of each arc-shaped side rod. The pressure rollers are arranged in a circumferential array based on the arc-shaped edge of the inner liner airbag body, and the pressure rollers are in close contact with the inner liner airbag body.

[0007] The above scheme ensures that the driven shaft and the pressure wheel work together to maintain uniform tension in the inner lining airbag body during the winding process.

[0008] Optionally, the auxiliary winding assembly further includes a bearing side plate, a low-speed motor, a drive shaft, a limiting slide rod, a pressure plate, a top plate, and a hydraulic telescopic column. The bearing side plate is fixedly installed on the top of the base plate and is symmetrically arranged with the base plate as the center. A low-speed motor is fixedly installed on one side of the bearing side plate, and a drive shaft is fixedly installed at the output end of the low-speed motor. A limiting slide rod is fixedly installed on the top of the bearing side plate and is symmetrically arranged with the bearing side plate as the center. A pressure plate is movably sleeved on one side of the limiting slide rod, and a top plate is fixedly installed on the top of the limiting slide rod. A hydraulic telescopic column is fixedly installed on the bottom of the pressure plate and is fixedly installed on the top of the bearing side plate for lifting the pressure plate.

[0009] The above solution uses a low-speed motor to drive the active rotating shaft and a hydraulic telescopic column to adjust the height of the pressure plate, achieving precise control.

[0010] Optionally, the inner liner airbag body is movably connected between the active rotating shaft and the pressure detection sleeve. The base plate is used to support the auxiliary winding assembly and the inner liner airbag body, and the bottom of the base plate is provided with an internal threaded hole for installing casters for easy movement.

[0011] The above design includes an internal threaded hole at the bottom of the base plate, which facilitates the installation of casters and improves the mobility of the device.

[0012] Optionally, the positioning plate includes a clamping device positioning seat disposed on the top of the inner airbag body and a clamping device positioning seat disposed on the bottom of the inner airbag body, and the curvature of the arc plate of the arc-shaped side rod is equal to the curvature of the edge of the inner airbag body.

[0013] The above solution ensures that the curvature of the arc-shaped side rod matches the curvature of the edge of the inner airbag body, thus ensuring a tight fit between the pressure rollers.

[0014] Optionally, the clamping roller is a hard roller, and the clamping rollers located at the top of the inner liner airbag body and the clamping rollers located at the bottom of the inner liner airbag body are staggered.

[0015] The above-mentioned design enhances the fixation effect on the inner airbag body by using staggered clamping rollers.

[0016] Optionally, the pressure detection sleeve has a built-in pressure sensor for recording the pressure on the inner airbag body in real time, providing data support for the height adjustment of the hydraulic telescopic column.

[0017] Through the above scheme, the pressure sensor provides data support for the height adjustment of the hydraulic telescopic column, ensuring the stability of the winding process.

[0018] Optionally, both the active and passive rotating shafts have anti-slip textures on their surfaces to enhance the fixation effect on the inner liner airbag body.

[0019] The above-mentioned design enhances the fixation of the pivot on the inner airbag body, preventing slippage.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] 1. This utility model, by setting up components such as a bearing side plate, a low-speed motor, a driving shaft, and a driven shaft, and through the coordination of power transmission between the low-speed motor and the driving shaft, enables the driving shaft to rotate under the drive of the low-speed motor. This achieves the effect that the device can rotate and drive the inner lining airbag body placed between the driving shaft and the driven shaft through the rotation of the driving shaft, thus providing a rotational basis for the subsequent winding process.

[0022] 2. This utility model, by setting up components such as a limiting slide rod, a pressure plate, a top plate, and a hydraulic telescopic column, and through the lifting cooperation between the hydraulic telescopic column and the pressure plate, allows the pressure plate to lift the pressure plate on the limiting slide rod by extending the hydraulic telescopic column. This enables the device to adjust the height of components such as the upper positioning plate and the pressing wheel by adjusting the hydraulic telescopic column, so as to better adapt to the pressing operation of airbag bodies of different sizes.

[0028] The following is in conjunction with the appendix Figure 1-4This application will be described in further detail.

[0029] This application discloses a pipeline lining airbag production apparatus.

[0030] Please see Figure 1 A pipe lining airbag production device includes a base plate 1, an auxiliary winding assembly 2 is provided on the top of the base plate 1, and an lining airbag body 3 is provided on one side of the auxiliary winding assembly 2.

[0031] Please see Figures 2 to 4 The auxiliary winding assembly 2 includes a driven rotating shaft 208, a pressure detection sleeve 209, a positioning plate 210, an arc-shaped side rod 211, and a pressing wheel 212. The driven rotating shaft 208 is movably installed on the left and right sides of the inner liner airbag body 3. The pressure detection sleeve 209 is fixedly sleeved on one side of the driven rotating shaft 208. The positioning plate 210 is located directly above the inner liner airbag body 3. The arc-shaped side rod 211 is fixedly installed at the bottom of the positioning plate 210, and the arc-shaped side rod 211 is symmetrically arranged with the inner liner airbag body 3 as the center. A pressing wheel 212 is movably installed on one side of the arc-shaped side rod 211. The pressing wheel 212 is arranged in a circumferential array based on the arc-shaped edge of the inner liner airbag body 3, and the pressing wheel 212 is in close contact with the inner liner airbag body 3.

[0032] The auxiliary winding assembly 2 also includes a bearing side plate 201, a low-speed motor 202, a drive shaft 203, a limiting slide rod 204, a pressure plate 205, a top plate 206, and a hydraulic telescopic column 207. The bearing side plate 201 is fixedly installed on the top of the base plate 1, and the bearing side plate 201 is symmetrically arranged with the base plate 1 as the center. The low-speed motor 202 is fixedly installed on one side of the bearing side plate 201, and the drive shaft 203 is fixedly installed at the output end of the low-speed motor 202. The limiting slide rod 204 is fixedly installed on the top of the bearing side plate 201, and the limiting slide rod 204 is symmetrically arranged with the bearing side plate 201 as the center. The pressure plate 205 is movably sleeved on one side of the limiting slide rod 204, and the top plate 206 is fixedly installed on the top of the limiting slide rod 204. The hydraulic telescopic column 207 is fixedly installed on the bottom of the pressure plate 205 and is fixedly installed on the top of the bearing side plate 201 for lifting the pressure plate 205.

[0033] The inner airbag body 3 is movably connected between the active rotating shaft 203 and the pressure detection sleeve 209. The base plate 1 is used to support the auxiliary winding assembly 2 and the inner airbag body 3. The bottom of the base plate 1 is provided with an internal threaded hole for installing casters for easy movement.

[0034] The positioning plate 210 includes a clamping positioning seat disposed on the top of the inner airbag body 3 and a clamping positioning seat disposed on the bottom of the inner airbag body 3. The curvature of the arc plate of the arc side rod 211 is equal to the curvature of the edge of the inner airbag body 3.

[0035] The pressure roller 212 is a hard roller, and the positions of the pressure roller 212 located at the top of the inner liner airbag body 3 and the pressure roller 212 located at the bottom of the inner liner airbag body 3 are staggered.

[0036] The pressure detection sleeve 209 has a built-in pressure sensor for recording the pressure on the inner liner airbag body 3 in real time, providing data support for the height adjustment of the hydraulic telescopic column 207.

[0037] Both the active rotating shaft 203 and the driven rotating shaft 208 have anti-slip textures on their surfaces to enhance the fixation effect on the inner airbag body 3.

[0038] Further explanation is needed: The bearing side plate 201 in the auxiliary winding assembly 2 is firmly installed on the top of the base plate 1. The low-speed motor 202 on it converts electrical energy into mechanical energy and is closely connected to the active rotating shaft 203 through the output end, forming an efficient power transmission path. When the low-speed motor 202 starts running, the active rotating shaft 203 rotates synchronously. The driven rotating shaft 208 is movably installed on both sides of the inner lining airbag body 3 and works in coordination with the active rotating shaft 203. In this process, the inner lining airbag body 3, which is placed between the active rotating shaft 203 and the driven rotating shaft 208, rotates due to the rotation of the active rotating shaft 203. This rotation effect provides the necessary foundation for the subsequent winding operation on the inner lining airbag body 3, so that the winding material can be wound evenly and orderly on the airbag body, ensuring the accuracy and efficiency of production.

[0039] The auxiliary winding assembly 2 is equipped with a limiting slide bar 204, a pressure plate 205, a top plate 206, and a hydraulic telescopic column 207. The hydraulic telescopic column 207 is fixed to the top of the bearing side plate 201. When the hydraulic telescopic column 207 extends during operation, its lifting force acts on the pressure plate 205, allowing the pressure plate 205 to move upward along the limiting slide bar 204. Since the pressure plate 205 is connected to the positioning plate 210 and other components above, as the pressure plate 205 is lifted, the height of the positioning plate 210 and the pressing wheel 212 installed on the arc-shaped side rod 211 at the bottom of the positioning plate 210 also changes accordingly. This height adjustment function allows the device to accurately adjust the contact position between the pressing wheel 212 and the inner lining airbag body 3 according to the actual needs of different sizes of inner lining airbag bodies 3, ensuring that the inner lining airbag body 3 of any size can be stably and effectively pressed during the production process, thereby improving the versatility and adaptability of the entire production device.

[0040] The implementation principle of a pipeline lining airbag production device according to an embodiment of this application is as follows:

[0041] First, place the pipe lining airbag production device in a suitable position. The internal threaded hole at the bottom of the base plate 1 can be used to install casters, which makes it easy to move the device to the work area and fix it. At this time, the auxiliary winding assembly 2 has been installed on the top of the base plate 1, and all components are ready.

[0042] Next, the low-speed motor 202 in the auxiliary winding assembly 2 is started. The low-speed motor 202 converts electrical energy into mechanical energy and drives the active rotating shaft 203 to rotate synchronously through the output end. Since the active rotating shaft 203 and the driven rotating shaft 208 work together, and the inner lining airbag body 3 is placed between the active rotating shaft 203 and the driven rotating shaft 208, the rotation of the active rotating shaft 203 drives the inner lining airbag body 3 to start rotating, preparing for the winding process.

[0043] Next, during the rotation of the inner airbag body 3, the pressure detection sleeve 209 starts to work. The pressure detection sleeve 209 has a built-in pressure sensor that monitors the pressure on the inner airbag body 3 during rotation in real time and feeds back the pressure data. This data provides a basis for the subsequent height adjustment of the hydraulic telescopic column 207.

[0044] Next, based on the data fed back by the pressure detection sleeve 209, the hydraulic telescopic column 207 starts to work. When it is necessary to adjust the height of the positioning plate 210 and the pressure roller 212, the hydraulic telescopic column 207 extends or shortens, and its lifting force acts on the pressure plate 205, causing the pressure plate 205 to move along the limit slide bar 204, thereby driving the positioning plate 210 connected to the pressure plate 205 and the pressure roller 212 installed on the arc-shaped side rod 211 at the bottom of the positioning plate 210 to change the height, ensuring that the pressure roller 212 can fit tightly against the inner liner airbag body 3 of different sizes.

[0045] Finally, after all the above preparations are completed, the winding operation is carried out. The winding material is placed in place, and as the inner lining airbag body 3 continues to rotate, the winding material is evenly and orderly wound on the airbag body, completing the production of the pipeline inner lining airbag.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
