Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, and in particular to a grinding device for the inner cavity of a marine valve. Background Technology

[0002] Marine valves are devices installed in various piping systems on ships to control the flow direction, pressure, and flow rate of fluids (such as water, steam, oil, etc.). These valves may accumulate dirt, rust, or wear due to long-term use and require regular maintenance to ensure their normal operation. For marine valves, keeping the inner cavity clean and smooth is very important.

[0003] Currently, grinding devices are usually required during the maintenance of valve cavities. However, when grinding and polishing valves, the grinding operation is basically done manually with a handheld grinder. However, manual grinding is inefficient, and the metal shavings produced by grinding are prone to flying, which can not only injure workers, but also increase the difficulty of subsequent cleaning. Utility Model Content

[0004] The purpose of this invention is to solve the problems that the manual grinding method used for grinding valves is inefficient, and the flying debris during grinding can easily injure workers and increase the difficulty of subsequent cleaning. Therefore, a grinding device for the inner cavity of marine valves is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A marine valve cavity grinding device includes a protective shell with a protective door rotatably mounted on it, a clamp fixedly mounted inside the protective shell, and further includes: a horizontal plate slidably mounted inside the protective shell, wherein a grinding machine is provided at the bottom of the horizontal plate and the output end of the grinding machine faces the clamp; an inclined plate rotatably connected inside the protective shell, wherein a through opening is provided on one side of the protective shell, and the side of the inclined plate away from its rotation axis is connected to the through opening by a spring; a driving part is provided on the protective shell, the driving part being used to drive the grinding machine to move up and down and to drive the inclined plate to swing up and down; and a collecting part is provided on one side of the protective shell.

[0007] To facilitate the discharge of metal shavings generated during grinding into a collection box, preferably, the drive unit includes a second motor fixedly mounted on the protective shell, a rotating rod rotatably connected to the protective shell, the output end of the second motor being fixedly connected to one end of the rotating rod, and a cam being fixedly connected to the other end of the rotating rod. When the rotating rod rotates, the cam intermittently slides over the bottom surface of the inclined plate, and a reciprocating component is provided on the protective shell.

[0008] To improve the polishing effect and efficiency of marine valves, the reciprocating component further includes a vertical plate fixedly connected to the top of the protective shell, a straight rod rotatably connected to the vertical plate, a turntable fixedly connected to one end of the straight rod, and pulleys connected to each other by belts fixedly connected to the other end of the straight rod and the surface of the turntable. A movable plate is longitudinally slidably connected to the protective shell, and a curved rod rotatably connected to the movable plate and eccentrically connected to the turntable. The horizontal plate is fixedly connected to the movable plate.

[0009] To assist in guiding the horizontal plate, preferably, guide grooves are provided on both sides of the inner wall of the protective shell, and guide rods are fixedly connected to both sides of the horizontal plate, with the guide rods slidably connected in the guide grooves.

[0010] For grinding the inner cavity of marine valves, preferably, the grinding machine includes a first motor and a wire grinding head, the first motor is fixedly installed at the bottom of the horizontal plate, and the wire grinding head is detachably installed on the output shaft of the first motor.

[0011] To facilitate the unified collection of metal debris, preferably, the collection unit includes a support plate fixedly connected to one side of the protective shell, a collection box is provided on the top of the support plate, and handles are fixedly connected to both sides of the collection box.

[0012] Compared with the prior art, this utility model provides a marine valve inner cavity grinding device, which has the following beneficial effects:

[0013] 1. The marine valve internal cavity grinding device can drive the wire grinding head to automatically rotate and grind the internal cavity of the marine valve by starting the second motor. This can make the wire grinding head contact the valve inner wall more evenly, thereby speeding up the grinding speed and improving the grinding effect and efficiency of the marine valve.

[0014] 2. The ship's valve cavity grinding device can also drive the cam to rotate by starting the second motor, causing one end of the inclined plate to swing up and down. This facilitates the discharge of metal debris that falls onto the inclined plate during grinding into the collection box, making it easier for workers to collect the metal debris generated during grinding. This reduces the difficulty of subsequent cleaning and indirectly improves work efficiency.

[0015] 3. The marine valve internal cavity grinding device, through the setting of protective shell and protective door, can shield the marine valve, which can not only prevent the flying chips generated during the grinding process from injuring the workers, but also limit the range of chip splashing, so that the chips fall smoothly onto the inclined plate, which helps to clean up the chips.

[0016] The parts of this device not covered are the same as or can be implemented using existing technology. This utility model solves the problem that the manual grinding method is inefficient when grinding valves, and the debris that flies out during grinding can not only easily injure workers, but also increase the difficulty of subsequent cleaning.

[0025] Example:

[0026] Reference Figures 1-5 This utility model provides a marine valve cavity grinding device, including a protective shell 1 with a protective door 2 rotatably installed, a clamp 3 fixedly installed inside the protective shell 1, and a horizontal plate 4 slidably installed inside the protective shell 1, wherein a grinding machine 5 is provided at the bottom of the horizontal plate 4, and the output end of the grinding machine 5 faces the clamp 3; an inclined plate 6 rotatably connected inside the protective shell 1, wherein a through opening 7 is provided on one side of the protective shell 1, and the side of the inclined plate 6 away from its rotation axis is connected to the through opening 7 by a spring; a driving part is provided on the protective shell 1, which is used to drive the grinding machine 5 to move up and down and drive the inclined plate 6 to swing up and down; and a collecting part is provided on one side of the protective shell 1.

[0027] Specifically, during use, by activating the drive unit, the wire grinding head 52 can be driven to automatically rotate and grind the inner cavity of the marine valve. This allows the wire grinding head 52 to make more uniform contact with the inner wall of the valve, thereby speeding up the grinding process and improving the grinding effect and efficiency of the marine valve. At the same time, it can also drive one end of the inclined plate 6 to swing up and down, which facilitates the discharge of metal debris that falls onto the inclined plate 6 during grinding into the collection box 11. This makes it convenient for workers to collect the metal debris generated during grinding, thereby reducing the difficulty of subsequent cleaning and indirectly improving work efficiency. Furthermore, the protective shell 1 and the protective door 2 can also shield the marine valve, preventing flying debris generated during grinding from injuring workers.

[0028] The drive unit includes a second motor 8 fixedly mounted on the protective shell 1. A rotating rod 81 is rotatably connected to the protective shell 1. The output end of the second motor 8 is fixedly connected to one end of the rotating rod 81. A cam 82 is fixedly connected to the other end of the rotating rod 81. When the rotating rod 81 rotates, the cam 82 intermittently slides over the bottom surface of the inclined plate 6. A reciprocating component is provided on the protective shell 1.

[0029] Specifically, during use, by starting the second motor 8, the output end of the second motor 8 drives the rotating rod 81 to rotate, and drives the cam 82 to rotate, so that the cam 82 intermittently slides over the bottom surface of the inclined plate 6, causing one end of the inclined plate 6 to swing up and down, which makes it easier to discharge the metal debris generated by grinding into the collection box 11.

[0030] Furthermore, when the rotating rod 81 rotates, it can also cause the reciprocating component to drive the horizontal plate 4 to move up and down, which is beneficial for the grinding machine 5 to better grind the marine valve.

[0031] The reciprocating component includes a vertical plate 9 fixedly connected to the top of the protective shell 1, a straight rod 91 rotatably connected to the vertical plate 9, a turntable 92 fixedly connected to one end of the straight rod 91, and pulleys 95 connected to each other by belts at the other end of the straight rod 91 and the surface of the rotating rod 81. A movable plate 94 is longitudinally slidably connected to the protective shell 1, and a curved rod 93 rotatably connected to the movable plate 94 and eccentrically connected to the turntable 92. A horizontal plate 4 is fixedly connected to the movable plate 94.

[0032] Specifically, in use, when the rotating rod 81 rotates, it drives the pulley 95, the straight rod 91 and the turntable 92 to rotate. The turntable 92 drives the moving plate 94 to move up and down reciprocally through the crank rod 93 on the principle of crank and slider. This drives the horizontal plate 4, the first motor 51 and the wire grinding head 52 to move synchronously. This allows the wire grinding head 52 to make more uniform contact with the inner wall of the valve, thereby speeding up the grinding process and improving the grinding effect and efficiency of marine valves.

[0033] Guide grooves 41 are provided on both sides of the inner wall of the protective shell 1, and guide rods 42 are fixedly connected to both sides of the horizontal plate 4. The guide rods 42 are slidably connected in the guide grooves 41.

[0034] Specifically, by setting the guide groove 41 and the guide rod 42, the horizontal plate 4 can be guided, thereby improving the stability of the horizontal plate 4 movement.

[0035] The grinding machine 5 includes a first motor 51 and a wire grinding head 52. The first motor 51 is fixedly installed at the bottom of the horizontal plate 4, and the wire grinding head 52 is detachably installed on the output shaft of the first motor 51.

[0036] Specifically, in use, by starting the first motor 51, the output end of the first motor 51 drives the wire grinding head 52 to rotate, which can grind the inner cavity of the marine valve.

[0037] The collection unit includes a support plate 10 fixedly connected to one side of the protective shell 1. A collection box 11 is provided on the top of the support plate 10, and handles 12 are fixedly connected to both sides of the collection box 11.

[0038] Specifically, the support plate 10, collection box 11 and handle 12 make it easy for workers to collect the metal shavings generated during grinding, thereby reducing the difficulty of subsequent cleaning.

[0039] Working principle: During use, the marine valve internal cavity grinding device first clamps and fixes the marine valve with clamp 3, then closes the protective door 2, then starts the first motor 51 to make the wire grinding head 52 rotate continuously, then starts the second motor 8. The output end of the second motor 8 drives the rotating rod 81, cam 82 and pulley 95 to rotate, and drives the straight rod 91 and turntable 92 to rotate. The turntable 92 drives the moving plate 94 to move up and down reciprocally through the crank rod 93 in the principle of crank and slider, and drives the horizontal plate 4, the first motor 51 and the wire grinding head 52 to move synchronously, so that the rotating wire grinding head 52 grinds the internal cavity of the marine valve up and down reciprocally.

[0040] Furthermore, when the cam 82 rotates, the cam 82 will intermittently slide over the bottom surface of the inclined plate 6 and drive one end of the inclined plate 6 to swing up and down, thereby discharging the metal debris that falls onto the inclined plate 6 during grinding into the collection box 11.

[0041] This grinding device, by starting the second motor 8, can drive the rotating wire grinding head 52 to automatically grind the inner cavity of the marine valve up and down. This allows the wire grinding head 52 to make more uniform contact with the inner wall of the valve, thereby speeding up the grinding process and improving the grinding effect and efficiency of the marine valve. It can also drive the cam 82 to rotate, causing one end of the inclined plate 6 to swing up and down. This facilitates the discharge of metal debris that falls onto the inclined plate 6 during grinding into the collection box 11, making it easier for workers to collect the metal debris generated during grinding. This reduces the difficulty of subsequent cleaning and indirectly improves work efficiency.

[0042] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
