Description

Technical Field

[0001] This utility model belongs to the field of pipeline installation and maintenance technology, specifically relating to an online temperature probe sleeve installation tool for pressurized pipelines. Background Technology

[0002] As a tool for installing online temperature probe sleeves on pressurized pipelines, an electric drill can drill holes of appropriate size in pressurized pipelines using a high-speed rotating drill bit to install the temperature probe sleeve. In this process, the electric drill needs to have sufficient power and speed to overcome the resistance of the pipeline material, while ensuring the accuracy and quality of the hole opening to avoid problems such as the hole diameter being too large or too small, or uneven hole walls, which would affect the subsequent installation and sealing performance of the sleeve.

[0003] In some existing technologies, when electric drills are used to drill on the surface of pressurized pipes, if a large amount of debris is scattered in the work area, covering the pipe surface and the surrounding environment, it may affect the operator's vision, making it difficult for them to accurately judge the location and depth of the borehole and the installation status of the casing. This increases installation errors, reduces installation accuracy, and may result in the temperature probe casing not being installed properly, affecting the accuracy of temperature measurement and the sealing of the pipe.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example

[0027] Reference Figures 1-5 This embodiment of the present invention provides an online temperature probe sleeve installation tool for pressurized pipelines, comprising:

[0028] The electric drill body 100 includes a housing 101, a chuck 102 fixedly mounted on the outer end face of the housing 101 by a bearing, a drive assembly 103 disposed in the inner cavity of the housing 101, and a push switch 104 adapted to be mounted on the inner surface of the housing 101.

[0029] It should be noted that the outer casing 101 is the external frame of the electric drill body 100, which protects the internal components and provides a mounting base for other parts. The chuck 102 is used to hold the drill rod 103e, enabling it to perform drilling operations stably. Driven by the servo motor 103a, the chuck 102 can drive the drill rod 103e to rotate synchronously. The servo motor 103a provides rotational power. After starting, it can drive the connecting column 103b and the drive gear 103c to rotate through the coupling. Then, through the cooperation of the drive gear 103c and the transmission gear 103d, the power is transmitted to the drill rod 103e inside the chuck 102, causing the drill rod 103e to rotate at high speed and drill the hole required for installing the temperature probe sleeve on the pressurized pipeline. The press switch 104 is used to control the start and stop of the electric drill body 100, thereby controlling the drilling and installation operations.

[0030] The drive assembly 103 includes a servo motor 103a disposed in the inner cavity of the housing 101, a connecting post 103b fixedly connected to the output end of the servo motor 103a via a coupling, a drive gear 103c fixedly sleeved on the outer surface of the connecting post 103b, a transmission gear 103d meshing with the outer surface of the drive gear 103c and used in conjunction with the chuck 102, and a drill rod 103e fixedly installed on the inner wall of the chuck 102.

[0031] The dust removal mechanism 200 includes a reversing component 201 for switching the direction of rotational power drive of the servo motor 103a and a dust suction component 202 for adsorbing drilling debris by the rotational power of the servo motor 103a.

[0032] Specifically, the reversing assembly 201 includes a slider 201a fixedly mounted on the outer surface of the servo motor 103a, a guide rail 201b fixedly connected to the inner wall of the housing 101 and used in conjunction with the slider 201a, a force-applying rod 201c fixedly connected to the other side of the slider 201a, and a limiting groove 201d opened on the outer surface of the housing 101 and used in conjunction with the force-applying rod 201c.

[0033] It should be noted that when it is necessary to switch the rotational power drive direction of the servo motor 103a, the force rod 201c is pushed along the inner wall of the limiting groove 201d, which drives the servo motor 103a and the slider 201a to move along the surface of the guide rail 201b, thereby changing the position of the servo motor 103a, and thus changing the meshing relationship between the drive gear 103c and other components, so as to realize the switching of the power drive direction to meet different operation requirements.

[0034] Furthermore, the vacuuming assembly 202 includes a fixed cylinder 202a communicating with the inner cavity of the housing 101, a mounting block 202b fixedly connected to the inner wall of the fixed cylinder 202a, a rotating shaft 202c rotatably connected to the inner surface of the mounting block 202b, a driven gear 202d fixedly sleeved on the outer end face of the rotating shaft 202c and used in conjunction with the drive gear 103c, and an impeller 202f fixedly installed at the other end of the rotating shaft 202c.

[0035] It should also be noted that when the moving servo motor 103a drives the drive gear 103c to the position where it meshes with the driven gear 202d, it can control the rotation of the drive gear 103c to drive the driven gear 202d to rotate. Then, through the cooperation between the driven gear 202d and the rotating shaft 202c, the impeller 202f is driven to rotate. The rotation of the impeller 202f generates suction force, which sucks the debris generated during the drilling process into the fixed cylinder 202a, preventing the debris from scattering and affecting the installation accuracy.

[0036] Preferably, the dust removal mechanism 200 includes a collection group 203 for preventing leakage of dust adsorbed by the dust collection assembly 202, and a locking assembly 204 for preventing displacement of the slider 201a.

[0037] It should be noted that the collection assembly 203 includes a filter screen 203a fixedly installed on the inner wall of the fixed cylinder 202a, a rotating rod 203b rotatably connected to the inner surfaces of both sides of the fixed cylinder 202a, a baffle 203c fixedly sleeved on the outer surface of the rotating rod 203b and used to seal the fixed cylinder 202a, and a torsion spring 203d sleeved on the outer surface of the rotating rod 203b and used to control the baffle 203c to close.

[0038] The suction force generated by the rotation of the impeller 202f pulls the baffle 203c into the fixed cylinder 202a, while the baffle 203c drives the debris into the fixed cylinder 202a. After the dust collection is completed, the torsion spring 203d returns to its original position, driving the rotating rod 203b to rotate. The rotation of the rotating rod 203b applies pressure to the torsion spring 203d, and the impurities are intercepted by the filter screen 203a, causing the impurities to concentrate in the fixed cylinder 202a. After the suction force generated by the rotation of the impeller 202f stops, the reaction force of the torsion spring 203d drives the rotating rod 203b and the baffle 203c to return to their original positions, thereby causing the baffle 203c to seal the fixed cylinder 202a and prevent the collected debris from leaking out.

[0039] Furthermore, the locking assembly 204 includes a fixing block 204a fixedly connected to both sides of the housing 101, a spring 204b fixedly connected to the inner wall of the fixing block 204a, a protrusion 204c fixedly connected to the other end of the spring 204b, and a concave block 204d fixedly installed on the outer end face of the force bar 201c and used in conjunction with the protrusion 204c.

[0040] It should be explained that when the position of the servo motor 103a moves to its maximum stroke, it can drive the concave block 204d to press the protrusion 204c through the force rod 201c. Under the action of the spring 204b, the protrusion 204c is embedded in the concave block 204d, thereby preventing the slider 201a from shifting position and ensuring the stability of the servo motor 103a.

[0041] Specifically, the slider 201a is slidably sleeved on the outer surface of the guide rail 201b, the outer surface of the force rod 201c slides in contact with the inner wall of the limiting groove 201d, the outer end face of the torsion spring 203d is fixedly connected to the outer surface of the fixed cylinder 202a, the other end of the torsion spring 203d is fixedly connected to the outer surface of the rotating rod 203b, and two sets of fixed blocks 204a are provided.

[0042] When in use, press switch 104 to start servo motor 103a. Servo motor 103a drives connecting column 103b and drive gear 103c to rotate synchronously. Then, through the cooperation of drive gear 103c and transmission gear 103d, drill rod 103e rotates at high speed, drilling the holes required for installing temperature probe sleeve on pressurized pipeline in sequence.

[0043] When a large amount of debris accumulates around the pipe: release switch 104 to stop the output end of servo motor 103a from rotating, overcome the pressure of spring 204b and protrusion 204c, push force rod 201c along the inner wall of limit groove 201d, drive concave block 204d to move to the position where protrusion 204c disengages, and then drive servo motor 103a and slider 201a to move along guide rail 201b;

[0044] When the servo motor 103a moves to its maximum stroke: the force bar 201c drives the concave block 204d to press the protrusion 204c. Under the action of the spring 204b, the protrusion 204c is embedded in the concave block 204d to prevent the slider 201a from shifting position and to ensure the stability of the servo motor 103a.

[0045] When the drive gear 103c moves with the servo motor 103a to the position where it meshes with the driven gear 202d: press the switch 104 again to start the servo motor 103a, which drives the drive gear 103c and the driven gear 202d to rotate, and then drives the impeller 202f to rotate through the driven gear 202d and generate suction.

[0046] At the same time, the rotating suction of the impeller 202f pulls the baffle 203c into the fixed cylinder 202a, allowing debris to enter. Meanwhile, the torsion spring 203d is compressed by the rotation of the rotating rod 203b, and the impurities are intercepted by the filter screen 203a.

[0047] After vacuuming is complete: release switch 104 to stop the impeller 202f from rotating. The reaction force of torsion spring 203d drives the rotating rod 203b and baffle 203c to reset, sealing the fixed cylinder 202a.

[0048] In summary, through the coordination of various components in the dust removal mechanism 200, the equipment can not only flexibly switch between drilling and dust removal operations, but also collect impurities to prevent debris accumulation from affecting the operator's judgment of the borehole location and depth, as well as the accuracy of casing installation. This ensures that the temperature probe casing can be installed in place, guaranteeing accurate temperature measurement and pipeline sealing.
