Description

Technical Field

[0001] The invention relates to the technical field of pipeline processing, and in particular to a pipeline hole opening device. Background Art

[0002] A pipeline is a long strip of structure used to transport fluids (such as liquids, gases or steam), usually made of metal (such as steel, copper), plastic or other corrosion-resistant materials. Pipelines are widely used in many fields such as industry, construction, and municipal engineering for water supply, drainage, gas supply, oil transportation, and chemical raw material transmission. At the branch line, a hole needs to be opened on the side of the pipeline to connect the branch pipeline.

[0003] For related technologies, reference may be made to the patent application with publication number CN116511557A, which discloses a pipe drilling machine, including a drilling mechanism and a clamping mechanism, wherein the drilling mechanism includes a drill bit, and the clamping mechanism includes a first clamping seat and a second clamping seat, wherein the first clamping seat and the second clamping seat are arranged opposite to each other, and the first clamping seat and the second clamping seat are used to clamp on the pipe to be drilled, and the drilling mechanism is connected to the clamping mechanism, and the advance and retreat direction of the drill bit is perpendicular to the axis direction of the first clamping seat and the second clamping seat. This can avoid slipping and dislocation during drilling, and make drilling more accurate.

[0004] With respect to the above-mentioned related technologies, during the process of opening a hole in a pipeline, the pressure at the hole opening position is usually relatively large, and excessive pressure will cause the pipeline to rotate or deform to a certain extent, thereby affecting the accuracy of the hole opening. Therefore, a pipeline hole opening device is urgently needed to solve the above-mentioned technical problems. Summary of the invention

[0005] In order to improve the accuracy of pipeline hole opening, the present invention provides a pipeline hole opening device.

[0006] The present invention provides a pipeline opening device, which adopts the following technical solution: A pipeline hole opening device comprises a base plate and a hole opening component arranged at one end of the base plate, wherein a pipeline is vertically arranged at one end of the base plate away from the hole opening component, and two arc-shaped clamping plates are arranged opposite to each other on two sides of the base plate, the arc-shaped clamping plates are arranged vertically, and the two arc-shaped clamping plates are arranged opposite to each other on two sides of the pipeline, two threaded rods are arranged in the base plate, the two threaded rods are coaxially fixedly connected, and the two threaded rods are extended along the width direction of the base plate, and the two arc-shaped clamping plates are respectively threadedly connected to the two threaded rods, a driving motor is provided on one side of the base plate, and the driving motor is coaxially fixedly connected to the threaded rod, and two clamping inner plates are also provided in the pipeline, the two clamping inner plates are relatively arranged on two sides of the pipeline, the clamping inner plates and the arc-shaped clamping plates are arranged one by one, and two threaded sections with different rotation directions are respectively provided on the threaded rods, and the clamping inner plates and the arc-shaped clamping plates are respectively threadedly connected to different threaded sections of the threaded rods.

[0007] By adopting the above technical solution, when it is necessary to drill a hole in the pipeline, the staff will place the pipeline on the side of the bottom plate away from the hole-opening component, and then start the driving motor. The driving motor drives the two threaded rods to rotate, so that the corresponding clamping inner plate and the arc-shaped clamping plate are close to each other, thereby fixing the two side walls of the pipeline and fixing the pipeline. Then, the side of the pipeline is drilled through the hole-opening component. During the drilling process, the internal stress generated during the drilling is effectively dispersed by setting the clamping inner plate, and the pipeline is rotated or deformed due to excessive pressure, which is beneficial to improving the accuracy of the drilling.

[0008] Optionally, the hole opening component includes a support platform, which is arranged on the upper end surface of the base plate, a lifting cylinder is provided on the support platform, the top end of the lifting cylinder is fixedly connected to the lifting platform, the upper end surface of the lifting platform is fixedly connected to the mounting frame, a hole opening motor is provided at the end of the lifting platform away from the pipeline, the output shaft of the hole opening motor passes through the mounting frame and is coaxially fixedly connected to a drill bit, the drill bit faces the pipeline, a driving screw is also provided in the base plate, the driving screw is extended along the length direction of the base plate, a moving motor is provided at one end of the base plate, the output shaft of the moving motor is coaxially fixedly connected to the driving screw, the support platform is slidably connected to the base plate, and the support platform is threadedly connected to the driving screw.

[0009] By adopting the above technical solution, when it is necessary to use the hole-opening component to drill a hole in the pipe, the staff first fixes the pipe by clamping the inner plate and the arc-shaped clamping plate, and then starts the hole-opening motor and the moving motor. The moving motor drives the driving screw to rotate, thereby moving the support platform toward the pipe, and the hole-opening motor drives the drill bit to rotate, thereby realizing the hole-opening processing of the pipe; when it is necessary to drill holes continuously at different heights of the pipe, the staff can start the lifting cylinder and adjust the height of the drill bit to drill holes at different heights. The operation is convenient and conducive to improving work efficiency.

[0010] Optionally, a support column is vertically provided at one end of the base plate away from the support platform, the support column is located between two clamping inner plates, and the support column is located in the pipeline.

[0011] By adopting the above technical solution, when it is necessary to place a pipeline, setting a support column is helpful to ensure the positioning of the pipeline, and a preliminary definition can be made on the position of the pipeline to avoid excessive deviation of the pipeline position, which affects the fixation, and is helpful to improve work efficiency.

[0012] Optionally, a plurality of cleaning brushes are provided on the outer side of the support column, and the cleaning brushes are arranged in a circumferential spiral. The bottom end of the support column passes through the bottom plate and is connected to the threaded rod through a bevel gear pair.

[0013] By adopting the above technical solution, a lot of debris will be generated in the process of drilling a hole in the pipeline, and some of the debris will stick to the inner wall of the pipeline. When the staff finishes drilling and needs to take the pipeline, the staff starts the drive motor, and the drive motor drives the threaded rod to rotate, thereby loosening the support and fixation of the pipeline. In this process, the threaded rod synchronously drives the support column to rotate through the bevel gear pair, and the rotation of the support column drives the cleaning brush to rotate, so that the cleaning brush cleans the inner wall of the pipeline, avoiding debris sticking to the inner wall of the pipeline, which increases unnecessary workload and is conducive to improving work efficiency.

[0014] Optionally, the clamping inner plate is an arc-shaped plate and a frame structure with a hollow middle portion. The clamping inner plate is also provided with a plurality of stabilizing rods for improving stability.

[0015] By adopting the above technical solution, the contact area between the cleaning brush and the inner wall of the pipe can be increased by setting it into a frame structure, thereby improving the cleaning efficiency. The setting of the stabilizing rod improves the overall stability of the clamping inner plate, which is beneficial to improving its fixing effect.

[0016] Optionally, an elastic layer is provided on a side of the clamping inner plate close to the pipe, and the elastic layer is evenly arranged.

[0017] By adopting the above technical solution and providing an elastic layer, a part of the pressure of the clamping inner plate on the inner wall of the pipeline can be dispersed to avoid damage to the pipeline due to excessive pressure, which is beneficial to improving the safety of the equipment.

[0018] Optionally, a protective cover is provided on the outside of the drill bit, one end of the protective cover is connected to the lifting platform, and the drill bit passes through the center of the protective cover.

[0019] By adopting the above technical solution and setting a protective cover, it is possible to prevent debris generated during the drilling process from splashing around and affecting subsequent cleaning work, which is beneficial to improving cleaning efficiency.

[0020] In summary, the present invention includes at least one of the following beneficial technical effects: 1. By setting the bottom plate, the hole-opening assembly, the pipe, the arc-shaped clamping plate, the threaded rod and the clamping inner plate, when the pipe needs to be opened, the staff will place the pipe on the side of the bottom plate away from the hole-opening assembly, and then start the driving motor, which drives the two threaded rods to rotate, so that the corresponding clamping inner plate and the arc-shaped clamping plate are close to each other, thereby fixing the two side walls of the pipe and fixing the pipe, and then the side of the pipe is opened through the hole-opening assembly. During the hole-opening process, the clamping inner plate is set to effectively disperse the internal stress generated during the hole-opening, and the excessive pressure will cause the pipe to rotate or deform, which is conducive to improving the accuracy of the hole-opening; 2. By setting a support platform, a lifting cylinder, a lifting platform, a mounting frame, a hole-opening motor, a drill bit, a driving screw and a moving motor, when the hole-opening assembly is needed to open a hole in the pipeline, the staff first fixes the pipeline by clamping the inner plate and the arc-shaped clamping plate, and then starts the hole-opening motor and the moving motor. The moving motor drives the driving screw to rotate, so that the support platform moves toward the pipeline, and the hole-opening motor drives the drill bit to rotate, thereby realizing the hole-opening processing of the pipeline; when it is necessary to open holes continuously at different heights of the pipeline, the staff can start the lifting cylinder and adjust the height of the drill bit to open holes at different heights, which is easy to operate and conducive to improving work efficiency; 3. By setting the support column and the cleaning brush, a lot of debris will be generated in the process of opening the hole in the pipe, and some of the debris will stick to the inner wall of the pipe. When the staff finishes opening the hole and needs to take the pipe, the staff starts the drive motor, and the drive motor drives the threaded rod to rotate, thereby loosening the support and fixation of the pipe. In this process, the threaded rod synchronously drives the support column to rotate through the bevel gear pair, and the rotation of the support column drives the cleaning brush to rotate, so that the cleaning brush cleans the inner wall of the pipe, avoiding debris sticking to the inner wall of the pipe, which increases unnecessary workload and is conducive to improving work efficiency.
