Description

Technical Field

[0001] The present application relates to the technical field of pipeline diversion construction, and in particular to a pressurized pipeline drilling device. Background Art

[0002] With the continuous development of my country's economic construction, urbanization is developing more and more rapidly. In order to ensure the water supply of residents, people are paying more and more attention to the construction of tap water pipelines.

[0003] During the construction of water pipelines, it is often necessary to divert the pipelines to meet the water needs of more residents. At present, when diverting water pipelines, it is necessary to close the valves of the water pipelines to suspend water supply, and then drill holes on the outer wall of the pipeline to connect the new diversion pipeline.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are defects in the water pipe diversion construction process that affect the normal water use of residents. Summary of the invention

[0005] In order to reduce the impact on residents' normal water use during the construction of tap water pipe diversion, the present application provides a pressurized pipe drilling device.

[0006] The present application provides a pressurized pipeline drilling device that adopts the following technical solution:

[0007] A pressurized pipeline drilling device, comprising a water distribution seat, a ball valve, a sealing connection component and a drilling mechanism;

[0008] The ball valve is fixedly connected to the water outlet end of the water distribution seat; the sealing connection assembly is detachably connected to the end of the ball valve away from the water distribution seat;

[0009] The drilling mechanism comprises a working chamber with one end detachably connected to a sealing connection assembly, a rotating assembly and a boosting assembly that drives the rotating assembly to move along the axis of the working chamber in a sliding manner connected to the working chamber;

[0010] The drilling mechanism also includes a drill bit located outside the working chamber and inside the sealing connection assembly, and the drill bit rotates driven by the rotating assembly.

[0011] By adopting the above technical scheme, when the pipeline is diverted, the ball valve and the water diversion seat are fixed on the pressurized pipeline, the drilling mechanism is sealed and connected to the ball valve through the sealing connection component, and the rotating component and the boosting component are started at the same time. Under the joint action of the boosting component and the rotating component, the drill bit gradually drills the pipeline downward along the axis direction of the working chamber. During the drilling process, the ball valve and the drilling mechanism are sealed and connected by the sealing connection component, so the water in the pipeline will not spray out, and the drilling diversion of the pipeline is realized without stopping the water supply in the pipeline, which effectively avoids the situation where the pipeline diversion construction affects the normal water use of residents, and greatly shortens the construction time and improves the construction efficiency.

[0012] Preferably, the rotating assembly comprises an air motor slidably connected to the working chamber, and a connecting rod arranged at the output end of the air motor;

[0013] A first drilling channel is opened at one end of the working chamber, the inner diameter of the drilling channel is equal to the outer diameter of the connecting rod, the connecting rod passes through the outside of the working chamber along the first drilling channel, and the drill bit is detachably connected to the connecting rod.

[0014] By adopting the above technical solution, the drill bit and the pneumatic motor are detachably connected through a connecting rod, which is convenient for construction workers to combine and install the rotating assembly and the drill bit; and the pneumatic motor is located inside the working chamber, and the drill bit is located outside the working chamber, which effectively prevents water flowing out of the pressurized pipeline along the pores from entering the working chamber when drilling the pressurized pipeline.

[0015] Preferably, a connection cover is coaxially arranged at one end of the working chamber away from the sealing connection assembly;

[0016] The boosting assembly comprises a lead screw nut coaxially arranged with the connection cover, and the lead screw nut penetrates the connection cover;

[0017] The boost mechanism also includes a rotating lead screw threadedly connected to the lead screw nut, and a driving member driving the rotating lead screw to rotate;

[0018] When the rotating screw rotates downward along the axis of the working chamber, the rotating assembly is pushed to move downward along the axis of the working chamber.

[0019] By adopting the above technical solution, the driving member drives the rotating screw to rotate, and the rotating screw rotates downward along the axis of the working chamber, while driving the rotating assembly to move downward along the axis of the working chamber, so that the drill bit contacts and presses the side wall of the pipe to perform drilling work on the side wall of the pipe.

[0020] Preferably, a protective connection assembly is provided between the rotating screw and the rotating assembly;

[0021] The protective connection assembly comprises a bearing coaxially fixedly connected to the rotating screw, and the outer ring of the bearing is coaxially fixedly connected to a connecting ring plate;

[0022] When the rotating lead screw rotates downward along the axis direction of the working chamber, the connecting ring plate slides downward along the axis direction of the working chamber.

[0023] By adopting the above technical solution, a protective connecting assembly is arranged between the rotating screw and the rotating component. When the rotating screw rotates downward along the axis of the working chamber, the connecting ring plate slides downward along the axis of the working chamber and pushes the rotating component to move downward along the axis of the working chamber, thereby avoiding direct contact between the rotating screw and the rotating component, and effectively preventing damage to the rotating component during the rotation of the rotating screw.

[0024] Preferably, the protective connection assembly further comprises a support plate fixedly connected to the rotating assembly, and the support plate is bolted to the support ring plate.

[0025] By adopting the above technical solution, the support ring plate and the support plate are fixedly connected by bolts, thereby improving the stability when the lead screw is rotated to push the rotating assembly to move downward along the axis of the working chamber.

[0026] Preferably, the sealed connection assembly includes a transfer chamber and a sealing chamber;

[0027] The transfer chamber comprises an upper connecting pipe, a water blocking plate and a lower connecting pipe which are coaxially arranged and integrally formed in sequence, the upper connecting pipe is threadedly connected to the working chamber, and the water blocking plate is provided with a second drilling channel for the connecting rod to pass through;

[0028] The sealing chamber is a cylinder with an opening at one end, the opening end of the sealing chamber is threadedly connected to the ball valve, the end of the sealing chamber away from the ball valve is threadedly connected to the lower connecting pipe, and a third drilling channel for the connecting rod to pass through is opened on the sealing chamber;

[0029] In addition, rubber rings are squeezed between the working chamber and the upper connecting pipe, and between the sealing chamber and the lower connecting pipe.

[0030] By adopting the above technical solution, the connecting rod passes through the first, second and third drilling channels in sequence and extends into the sealing chamber and is connected to the drill bit. When the drill bit is drilling, the water flowing out of the pressurized pipeline along the pores enters the sealing chamber and is blocked, thereby effectively avoiding the free spraying of water in the pressurized pipeline during the drilling process.

[0031] Preferably, the connecting rod is detachably connected to the output end of the pneumatic motor.

[0032] By adopting the above technical solution, the connecting rod and the pneumatic motor can be detachably connected, which is convenient for construction workers to assemble the drilling mechanism and to adjust the length of the connecting rod according to actual conditions, thereby effectively improving the scope of application.

[0033] Preferably, a muffler is provided on the pneumatic motor.

[0034] By adopting the above technical solution, a muffler is arranged on the pneumatic motor to reduce the noise when the drilling device drills holes in the pipeline, thereby preventing the normal life of residents from being affected.

[0035] Preferably, the driving member is a driving motor, and the output end of the driving motor is coaxially and fixedly connected to the rotating screw.

[0036] By adopting the above technical solution, the driving member is a driving motor, and the driving motor is controlled to drive the rotating screw to rotate instead of the traditional manual rotation method, which effectively reduces the workload of construction workers.

[0037] In summary, the present application includes at least one of the following beneficial technical effects:

[0038] 1. When diverting the pipeline, fix the ball valve and the water diversion seat on the pressurized pipeline, seal the drilling mechanism with the ball valve through the sealing connection component, and start the rotating component and the boosting component at the same time. Under the joint action of the boosting component and the rotating component, the drill bit gradually drills the pipeline downward along the axis of the working chamber. During the drilling process, the sealing connection component seals the ball valve and the drilling mechanism, so the water in the pipeline will not spray out. The drilling diversion of the pipeline is achieved without stopping the water supply in the pipeline, which effectively avoids the situation where the pipeline diversion construction affects the normal water use of residents, and greatly shortens the construction time and improves the construction efficiency;

[0039] 2. A protective connection assembly is provided between the rotating screw and the rotating assembly. When the rotating screw rotates downward along the axis of the working chamber, the connecting ring plate slides downward along the axis of the working chamber and pushes the rotating assembly to move downward along the axis of the working chamber, thereby avoiding direct contact between the rotating screw and the rotating assembly, and effectively preventing damage to the rotating assembly during the rotation of the rotating screw;

[0040] 3. The connecting rod and the pneumatic motor are detachably connected, which is convenient for construction workers to assemble the drilling mechanism and adjust the length of the connecting rod according to actual conditions, effectively improving the scope of application.
