Description

Technical Field

[0001] The invention relates to the technical field of pipeline grinding, in particular to a grinding device for casting wear-resistant pipelines. Background Art

[0002] Cast wear-resistant pipes are specially designed for conveying and handling materials in highly abrasive environments. They are often used in industrial production, especially in those occasions where the wear resistance of the pipe is extremely high. The inner wall of these pipes is specially treated to ensure that they can withstand long-term friction and impact without rapid wear or damage. In order to improve the wear resistance and service life of the pipe, it is necessary to grind the inner wall of the pipe.

[0003] At present, when grinding the inner wall of the pipeline, due to the limitation of the internal space of the pipeline, workers often need to use smaller grinding discs and constantly rotate the grinding equipment to ensure that every part of the inner wall of the pipeline can be evenly ground. On this basis, it is also necessary to continuously extend the equipment into the interior of the pipeline. However, this method is not only labor-intensive, but also due to the complex structure inside the pipeline, it is easy to have dead corners that are not polished in place, which may affect the wear resistance and service life of the pipeline. Summary of the invention

[0004] The object of the present invention is to provide a grinding device for cast wear-resistant pipes to solve at least one technical problem existing in the above-mentioned prior art.

[0005] To achieve the above object, the present invention provides the following technical solution: a grinding device for casting wear-resistant pipes, comprising

[0006] The mounting mechanism comprises a housing, a protective cover fixedly connected to one end of the housing, and protective silica gel fixedly connected to the other end of the housing, wherein a driving component is arranged inside the housing;

[0007] The output mechanism includes an output rod arranged inside the shell, an inner groove opened inside the output rod, and a pin hole opened on the end face of the output rod.

[0019] Wherein, the guide rod is located inside the guide groove, and the guide rod can slide along the inside of the guide groove.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. When grinding inside the pipe, the operator first needs to connect the wires to the power supply.

The equipment can rotate continuously to complete the circular grinding, improving the convenience of operation and the life of the pipe. After the power is connected, the motor drives the drive shaft and the transmission ring to rotate. When the output rod slides, the pin hole may be aligned and engaged with the pin rod, or the first spring may need to be compressed and aligned again. In both cases, the equipment can ensure normal operation. The overall operation of the equipment is more convenient and simple while ensuring normal operation, so that the inner wall of the pipe can be effectively polished and the overall life of the pipe can be improved.

[0023] 3. When the paddle is pushed, the guide rod of the U-shaped rod slides along the straight groove, allowing the grinding ball to extend out of the protective cover for grinding. After the paddle is released, the second spring resets the slip ring, the pin rod separates from the pin hole, the output rod stops rotating, and the grinding part is retracted into the protective cover. This design not only protects the equipment and pipelines, but also improves the convenience and safety of operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1;

[0038] See also Figures 1 to 3 The present invention provides a technical solution: a grinding device for casting wear-resistant pipes, comprising

[0039] The mounting mechanism 1 comprises a housing 11, a protective cover 12 fixedly connected to one end of the housing 11, and a protective silica gel 13 fixedly connected to the other end of the housing 11, and a driving component 14 is arranged inside the housing 11;

[0040] The output mechanism 2 includes an output rod 21 arranged inside the housing 11, an inner groove 22 opened inside the output rod 21, and a pin hole 23 opened on the end face of the output rod 21. An operating component 24 is arranged on the outer side of the output rod 21, a grinding component 25 is adapted to be installed inside the inner groove 22, and a guide component 26 is adapted to be installed inside the housing 11.

[0041] Furthermore, a groove 111 is formed on the outer side of the housing 11 , a heat dissipation hole plate 112 is arranged on the outer side of the housing 11 , and a sliding groove 113 is formed on a side of the housing 11 facing the groove 111 .

[0042] In summary, when performing internal grinding operations on the pipeline, the operator first needs to connect the wire 142 to the power supply. Then, they need to hold the housing 11 and ensure that the index finger, middle finger and ring finger are placed in the three sets of grooves 111 respectively to enhance the grip stability and prevent the device from slipping out of the hand during use, thereby avoiding accidents. In addition, the heat dissipation hole plate 112 design on the housing 11 helps to dissipate the heat generated by the driving component 14 during operation in a timely manner. This helps prevent the equipment from shutting down due to overheating and ensures the continuity and safety of the grinding operation.

[0043] Embodiment 2: This embodiment is based on embodiment 1. For details, please refer to Figures 1 to 9 The driving component 14 includes a motor 141 adapted to be installed inside the housing 11, a wire 142 arranged at one end of the motor 141, and a driving shaft 143 fixedly connected to the output end of the motor 141, and a transmission assembly 144 is arranged on the outer side of the driving shaft 143.

[0044] Furthermore, the wire 142 is electrically connected to the motor 141 , and the wire 142 extends through the housing 11 and the center of the protective silicone 13 . Two sets of convex rings are provided on the outer side of the driving shaft 143 , and the transmission assembly 144 is located between the two sets of convex rings.

[0045] Furthermore, the transmission assembly 144 includes a transmission ring 1441 fixedly connected to the outside of the driving shaft 143, and a circular hole 1442 starting at one end of the transmission ring 1441;

[0046] The number of the round holes 1442 is the same as the number of the pin holes 23 .

[0047] It should be noted that the transmission ring 1441 also includes a first spring 1443 fixedly connected to the bottom end of the circular hole 1442 , and a pin rod 1444 fixedly connected to one end of the first spring 1443 , and the pin rod 1444 is slidably connected inside the circular hole 1442 .

[0048] Preferably, the operating component 24 includes a slip ring 241 slidably connected to the inside of the housing 11, a dial plate 242 fixedly connected to the outside of the slip ring 241, and a second spring 243 fixedly connected to one end of the slip ring 241, and the other end of the second spring 243 is connected to the inside of the housing 11;

[0049] The shifting plate 242 is located inside the sliding groove 113 and slides therein, and the output rod 21 is rotatably connected to the inner wall of the slip ring 241 .

[0050] When the operator holds the device, he first extends the end of the device with the protective cover 12 into the inner wall of the pipe, and then presses the dial plate 242 with his thumb while pushing the dial plate 242. At this time, the dial plate 242 will slide along the inside of the slide groove 113, and at the same time drive the slip ring 241 at the bottom of the dial plate 242 to slide inside the housing 11. The slip ring 241 can drive the output rod 21 to slide inside the housing 11 until the pin hole 23 inside the output rod 21 is fully engaged with the pin rod 1444. The sliding slip ring 241 will squeeze the second spring 243 to cause the second spring 243 to contract.

[0051] At this time, the sliding of the output rod 21 will drive the grinding component 25 to protrude from the inside of the protective cover 12, ensuring that the inner wall of the pipeline is polished. At the same time, due to the complete engagement of the pin hole 23 and the pin rod 1444, the motor 141 can be connected to the power supply for rotation, and the output rod 21 can be driven to rotate by the drive shaft 143, and the grinding component that has been protruded can be used to achieve the grinding of the inner wall of the pipeline. Since the output rod 21 drives the grinding component 25 to rotate continuously, the annular grinding of the inner wall of the pipeline can be directly achieved, and the equipment can be gradually extended to the inside of the pipeline to complete the grinding of the pipeline. Compared with the traditional grinding method, the overall operation method of grinding the inner wall of the pipeline by this device is more convenient and simple. It only needs to continuously extend the equipment to the inside of the pipeline, so as to ensure that the inner wall of the pipeline is effectively polished and the overall life of the pipeline is improved.

[0052] When the power source is connected, the motor 141 will drive the drive shaft 143 and the transmission ring 1441 outside the drive shaft 143 to rotate continuously. When the output rod 21 slides toward the transmission ring 1441, two situations will occur:

[0053] The first one is that the pin hole 23 is aligned with the pin rod 1444 to achieve a snap connection, driving the output rod 21 to rotate.

[0054] The second is that the pin hole 23 is not aligned with the pin rod 1444 to achieve snap connection. At this time, the pin rod 1444 will squeeze the inner end surface of the output rod 21, causing the pin rod 1444 to slide into the inside of the circular hole 1442 under the action of squeezing, and squeeze the first spring 1443 to shrink it, until the rotating transmission ring 1441 drives the pin rod 1444 to align with the pin hole 23 again. Then, under the elasticity of the first spring 1443, the pin rod 1444 is driven to be inserted into the pin hole 23 to achieve snap connection, and the output rod 21 is driven to rotate.

[0055] No matter which of the above conditions occurs, it can be ensured that the pin rod 1444 is engaged with the pin hole 23, ensuring that the device can operate normally.

[0056] In summary, when using the pipeline inner wall grinding equipment, the operator extends one end of the equipment into the pipeline, and drives the output rod 21 to move by pushing the dial plate 242 until the pin hole 23 is engaged with the pin rod 1444. After the motor 141 is started, the output rod 21 is driven to rotate through the drive shaft 143, so that the grinding component 25 extends out of the protective cover 12 for grinding. The equipment can rotate continuously to complete the annular grinding, improving the convenience of operation and the life of the pipeline. After the power is connected, the motor drives the drive shaft and the transmission ring 1441 to rotate. When the output rod 21 slides, the pin hole 23 may be aligned and engaged with the pin rod 1444, or the first spring 1443 may need to be compressed and aligned and engaged again. In both cases, the equipment can ensure normal operation. The overall operation of the equipment is more convenient and simple while ensuring normal operation, so that the inner wall of the pipeline can be effectively polished and the overall life of the pipeline can be improved.

[0057] Embodiment 3, this embodiment is based on Embodiment 1 and Embodiment 2, and can refer to Figures 1 to 9 The specific method is as follows: the grinding component 25 includes a U-shaped rod 251 slidably connected to the inside of the inner groove 22, a grinding ball 252 fixedly connected to one end of the U-shaped rod 251, and a guide rod 253 fixedly connected to the outside of the other end of the U-shaped rod 251.

[0058] Furthermore, the guide component 26 includes a swivel ring 261 rotatably connected to the inside of the housing 11 , a mounting groove 262 formed on the inner wall of the swivel ring 261 , and guide grooves 263 formed on both sides of the inner wall of the mounting groove 262 .

[0059] Furthermore, the guide groove 263 includes a straight groove 2631 and an oblique groove 2632, and the guide groove 263 is formed by the straight groove 2631 and the oblique groove 2632;

[0060] The guide rod 253 is located inside the guide groove 263 , and the guide rod 253 can slide along the inside of the guide groove 263 .

[0061] When the push plate 242 drives the output rod 21 to slide through the slip ring 241, the guide rod 253 at one end of the U-shaped rod 251 will slide along the inside of the straight groove 2631. When the grinding ball 252 leaves the inside of the protective cover 12, the guide rod 253 at one end of the U-shaped rod 251 will enter the inclined groove 2632. During the subsequent sliding process of the output rod 21, the guide rod 253 at one end of the U-shaped rod 251 will expand outward with the guidance of the inclined groove 2632, thereby driving the grinding ball 252 at the other end of the U-shaped rod 251 to contact the inner wall of the pipe, ensuring that the grinding work can be achieved.

[0062] The design of the expandable grinding ball 252 can not only ensure that when the equipment is not in use, the grinding ball 252 can be effectively protected by the U-shaped rod 251, thereby improving the overall service life of the equipment to a certain extent, but also ensure that the operator can extend the equipment into the inner wall of the pipe more easily without initial friction, thereby further improving the overall operation convenience of the equipment.

[0063] At the same time, when the operator releases the paddle 242, the elasticity of the second spring 243 will drive the slip ring 241 to reset, thereby causing the pin 1444 to separate from the pin hole 23, causing the output rod 21 to stop rotating and driving the grinding component on the outside of the output rod 21 back to the inside of the protective cover 12. This method can not only prevent the operator from letting go of the device and causing unnecessary damage to the inner wall of the pipeline due to continuous rotation, but also can cause the grinding ball 252 to separate from the inner wall of the pipeline after the grinding work is in contact, which is not only more convenient to remove, but also prevents the device from getting stuck inside the pipeline. It can protect both the device and the pipeline, achieving a double-layer protection effect.

[0064] In summary, when the paddle 242 is pushed, the guide rod 253 of the U-shaped rod 251 slides along the straight groove 2631, so that the grinding ball 252 extends out of the protective cover 12 for grinding. After the paddle 242 is released, the second spring 243 acts to reset the slip ring 241, the pin 1444 separates from the pin hole 23, the output rod 21 stops rotating, and the grinding component is retracted into the protective cover. This design not only protects the equipment and pipelines, but also improves the convenience and safety of operation.

[0065] Embodiment 4: This embodiment is based on the overall operation mode of the above embodiment, which can be referred to Figures 1 to 9 , the specific method is as follows:

[0066] When grinding the inner wall of the pipe, the operator first needs to ensure that the power cord 142 is connected to the power supply. The operator needs to hold the housing 11 of the device tightly and put the index finger, middle finger and ring finger into the three sets of grooves 111 respectively to ensure a stable grip of the device during operation to prevent accidents caused by instability.

[0067] The operator inserts one end of the device into the pipe, and then pushes the dial plate 242 to move the output rod 21 until the pin hole 23 and the pin rod 1444 are locked together. Once the motor 141 is powered on and starts running, the drive shaft 143 drives the output rod 21 to rotate, and the grinding ball 252 will extend from the protective cover 12 and contact the inner wall of the pipe to perform grinding.

[0068] When the operator releases the paddle 242, the second spring 243 will force the slide ring 241 to return to the initial position, causing the pin 1444 to separate from the pin hole 23, so that the output rod 21 will stop rotating and pull the grinding component back into the protective cover 12. This design not only simplifies the operation process, but also ensures the safety of equipment and pipelines, and prevents possible damage caused by improper operation.

[0069] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
