Description

Technical Field

[0001] This utility model relates to the field of pipe end grinding technology, specifically a CPVC cable protection pipe end grinding device. Background Technology

[0002] CPVC cable protection pipe is a type of pipe made by extrusion processing with chlorinated polyvinyl chloride (CPVC) resin as the main raw material and the addition of specific additives. It is specially designed to protect cables and has the characteristics of high temperature resistance, flame retardancy, good insulation, high mechanical strength and corrosion resistance. It can effectively resist the damage of external environment to cables and ensure the safe and stable operation of cables in various complex environments.

[0003] The CPVC cable protection pipe end grinding device is a special equipment used to grind the ends of CPVC cable protection pipes. In outdoor power construction, communication line laying and other projects, the installation and maintenance of CPVC cable protection pipes are common tasks. Currently, when grinding the ends of CPVC cable protection pipes, construction workers mostly use handheld grinders to perform parallel grinding operations on the pipe end face.

[0004] Due to the limitations of handheld grinders, it is difficult to precisely control the grinding force and angle. After grinding the end face of the pipe, burrs and unevenness are very likely to appear on both the inner and outer sides of the end face. Outdoor working environments are relatively simple, lacking effective fine processing tools and conditions. These burrs and uneven parts are difficult to properly handle. These residual burrs and unevenness can easily scratch the skin of workers when they perform related operations, posing a safety hazard to outdoor construction workers. Therefore, a CPVC cable protection pipe end grinding device is proposed to address the above problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0032] Please see Figures 1-7 This utility model provides a technical solution:

[0033] A grinding device for CPVC cable protection pipe ends includes a support cylinder 1. A spring retraction rod 2 is rotatably connected to the front end of the support cylinder 1. A power motor 4 is fixedly connected to the front end inside the support cylinder 1. The drive shaft of the power motor 4 is fixedly connected to the rear end of the spring retraction rod 2. A pipe end fixing assembly 5 is installed at the rear of the support cylinder 1. A connecting seat 3 is fixedly connected to the telescopic end of the spring retraction rod 2. Adjustment assemblies 6 are fixedly connected to both ends of the connecting seat 3. A grinding execution assembly 7 is slidably mounted on the surface of the adjustment assembly 6. The grinding execution assembly 7 includes an adjusting nut 71, which is threadedly connected to a one-way screw 62. On the outer side, a second adjusting rail 72 is fixedly connected to the front end face of the adjusting nut 71. A first grinding plate 73 is fixedly connected to the middle of the front end face of the second adjusting rail 72 via a mounting seat. A second grinding plate 74 is hinged to both ends of the first grinding plate 73. A transmission rod 75 is hinged to the back of the second grinding plate 74. An adjusting seat 76 is hinged to the rear end of the transmission rod 75. The adjusting seat 76 is slidably disposed on the inner side of the second adjusting rail 72. A protective plate 77 is fixedly connected to one end of the adjusting seat 76. A bidirectional screw 78 is rotatably connected inside the second adjusting rail 72. Protective linkage components 79 are fixedly connected to both ends of the second adjusting rail 72.

[0034] As a further implementation of this solution, the adjustment component 6 includes a first adjustment rail 61, with a one-way screw 62 rotatably connected to the inner side of the first adjustment rail 61. Both sides of the inner wall of the first adjustment rail 61 are provided with toothed grooves 63. This design enables flexible adjustment of the position of the grinding execution component 7.

[0035] As a further implementation of this solution, the protective linkage component 79 includes a linkage block 791. A metal spring 792 is fixedly connected to the rear end face of the linkage block 791. The metal spring 792 has a U-shaped structure and is located inside the first adjusting rail 61. Arc-shaped blocks 793 are fixedly connected to both sides of the metal spring 792. The arc-shaped blocks 793 slide with the toothed groove 63. A brush 794 is fixedly connected to the rear end face of the arc-shaped blocks 793. The rear end of the brush 794 is in contact with the surface of the one-way screw 62. A guide groove 795 is provided on one side of the linkage block 791. The guide groove 795 slides with the protective plate 77, ensuring the stability of the protective plate 77 during movement. At the same time, it can also provide good protection for the bidirectional screw 78, preventing grinding debris from entering the bidirectional screw 78, thereby extending its service life.

[0036] As a further implementation of this solution, the two adjustment seats 76 inside each second adjustment rail 72 are symmetrically distributed. The inner sides of the two adjustment seats 76 are threadedly connected to the two sides of the bidirectional screw 78 respectively. One end of the second adjustment rail 72 is rotatably connected to an adjustment head 8. One end of the adjustment head 8 extends to the outside of the linkage block 791, and the other end of the adjustment head 8 is fixedly connected to one end of the bidirectional screw 78. This allows the operator to precisely control the movement of the adjustment seat 76 by manually rotating the adjustment head 8, thereby precisely adjusting the angle of the second grinding plate 74 to adapt to different grinding needs.

[0037] As a further implementation of this solution, a corrugated dustproof plate 64 is slidably connected to the front end of the inner side of the first adjusting rail 61. One end of the corrugated dustproof plate 64 is fixedly connected to the linkage block 791. The two first adjusting rails 61 are located on the same central axis. One end of the one-way screw 62 is rotatably connected to a drive head 65. One end of the drive head 65 is fixedly connected to one end of the one-way screw 62. The corrugated dustproof plate 64 has good extensibility, effectively blocking grinding debris from entering the interior of the first adjusting rail 61, preventing debris from affecting the one-way screw 62 and other internal components, ensuring a clean environment inside the first adjusting rail 61, and maintaining the normal operation of the one-way screw 62.

[0038] As a further implementation of this solution, the pipe fixing assembly 5 includes an electric cylinder 51. A connecting rod 52 is fixedly connected to the telescopic end of the electric cylinder 51. A first connecting rod 53 is hinged to the outer side of the connecting rod 52. A clamping plate 54 is hinged to one end of the first connecting rod 53. Corrugated rubber anti-slip strips 55 are fixedly connected to both sides of the outer wall of the clamping plate 54. An airbag 56 is fixedly connected to the middle of the outer wall of the clamping plate 54. A second connecting rod 57 is hinged to the outer wall of the electric cylinder 51. One end of the second connecting rod 57 is hinged to the back of the clamping plate 54. A fixing rod 58 is fixedly connected to the front end of the electric cylinder 51. The fixing rod 58 is fixedly connected to the support cylinder 1, and the interior of the support cylinder 1 is a hollow structure. The inner side of the support cylinder 1 is slidably connected to the front end of the connecting rod 52. The corrugated rubber anti-slip strip 55 increases the friction between the clamping plate 54 and the pipe wall, preventing the pipe from sliding during the grinding process. The airbag 56 can fit tightly against the pipe wall, effectively offsetting the torque generated by the rotation of the adjusting component 6, ensuring the stability of the pipe during the grinding process. The fixing rod 58 firmly connects the electric cylinder 51 to the support cylinder 1, ensuring the structural stability of the entire pipe fixing component 5. At the same time, the cavity structure of the support cylinder 1 and the sliding connection with the connecting rod 52 provide space and guidance for the movement of the connecting rod 52, enabling the pipe fixing component 5 to smoothly achieve the fixing and loosening operation of the pipe.

[0039] Workflow: Place the pipe fixing component 5 inside the CPVC cable protection pipe to be ground, and align the adjusting component 6 with the pipe opening of the CPVC cable protection pipe to be ground. Then, activate the pipe fixing component 5. The telescopic end of the electric cylinder 51 pushes the connecting rod 52 forward. The first connecting rod 53 hinged to the outer wall of the connecting rod 52 and the second connecting rod 57 hinged to the outer wall of the electric cylinder 51 work together to extend the clamping plate 54 outward, so that the clamping plate 54 comes into contact with the pipe wall. The clamping plate 54 drives the wavy rubber anti-slip strip 55 and the airbag 56 to move synchronously. The wavy rubber anti-slip strip 55 can increase the friction between the pipe and the pipe wall, and the airbag 56 can fit tightly against the pipe wall, thereby counteracting the torque generated by the rotation of the adjusting component 6 later, and stably fixing the pipe to ensure that the pipe will not shake during grinding.

[0040] Next, according to the diameter of the CPVC cable protection pipe, the drive head 65 is rotated, causing the one-way screw 62 to rotate within the first adjusting rail 61. This causes the adjusting nut 71, threaded onto the outside of the one-way screw 62, to move up and down along the one-way screw 62, thereby adjusting the position of the grinding execution component 7 to adapt to the grinding needs of pipes with different diameters. Then, the adjusting head 8 is rotated, causing the bidirectional screw 78 to rotate in the forward direction. Since the two adjusting seats 76 are threaded onto both sides of the bidirectional screw 78 and are symmetrically distributed, the rotation of the bidirectional screw 78 causes the two adjusting seats 76 to move in opposite directions, thereby pulling the hinged transmission rod 75 to move synchronously, changing the tilt angle of the corresponding second grinding plate 74, allowing the second grinding plate 74 to grind burrs and debris from both sides of the pipe end face. In preparation for grinding, the first grinding plate 73 is responsible for grinding the end face of the pipe opening. It should be added that during the movement of the grinding execution component 7, the adjusting nut 71 can drive the protective linkage component 79 to move synchronously. The arc-shaped blocks 793 on both sides of the metal spring 792 slide with the toothed groove 63 on the inner side of the first adjusting rail 61 to generate vibration, which causes the debris attached to the first grinding plate 73 and the second grinding plate 74 to fall off quickly, which can prevent foreign objects from scratching the pipe opening. At the same time, the protective plate 77 moves synchronously with the adjusting seat 76 to prevent grinding debris from entering the bidirectional screw 78 and improve the service life of the bidirectional screw 78. The corrugated plate and corrugated dustproof plate 64 prevent debris from entering the interior of the first adjusting rail 61, ensuring the cleanliness of the device interior and maintaining the normal operation of the unidirectional screw 62.

[0041] Next, the power motor 4 is turned on, which drives the spring retraction rod 2 to rotate, causing the entire adjustment assembly 6 and the grinding execution assembly 7 to rotate around the pipe opening. At this time, the first grinding plate 73 grinds the front end face of the pipe opening, relying on its rotational motion to remove the uneven parts of the front end face of the pipe opening, making the pipe opening end face initially flat. The second grinding plate 74 is responsible for grinding the burrs and debris on both sides of the pipe opening end face. After grinding is completed, the pipe opening fixing assembly 5 is operated in reverse to retract the clamp 54, loosen the fixation on the pipe, and remove the CPVC cable protection pipe opening grinding device for subsequent processing.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
