Technical Field

[0001] This utility model relates to the technical field of busbar cylinder grinding equipment, and in particular to a grinding device for busbar cylinder production. Background Technology

[0002] In GIS (Gas Insulated Switchgear) and GIL (Gas Insulated Line Transmission) equipment, the busbar cylinder is a critical component, and the smoothness of its inner wall directly affects the insulation performance and operational safety of the equipment. However, burrs or uneven areas are inevitably generated during the processing of the busbar cylinder, which need to be eliminated through grinding. Existing grinding equipment has the following drawbacks:

[0003] Traditional grinding tools suffer from poor adaptability. They typically use grinding heads of fixed sizes, making it difficult to adapt to busbar cylinders of different diameters. This is especially true for large-diameter or non-standard cylinders, requiring frequent replacement of grinding components and resulting in low efficiency. Therefore, there is an urgent need for a grinding device that can flexibly adjust the grinding diameter and meet the grinding requirements of the inner walls of busbar cylinders with various diameters. Utility Model Content

[0004] The purpose of this invention is to provide a grinding device for busbar cylinder production, which can flexibly adjust the grinding diameter according to requirements, eliminates the need for frequent grinding head replacements, expands the applicability of this invention, and improves the convenience of busbar cylinder grinding.

[0005] The present invention adopts the following technical solution:

[0006] A grinding device for busbar cylinder production includes a support platform. A grinding section driven by a grinding motor is provided on the support platform. The grinding section includes a central main shaft. Multiple support plates are spaced apart along the circumference of the main shaft. Grinding discs are provided on the support plates.

[0010] Preferably, the fixing sleeve has a receiving cavity along its circumference, and the fixing sleeve has a spray hole communicating with the receiving cavity; a stretchable bamboo-joint hose is provided on one side of the receiving cavity, and the bamboo-joint hose is communicating with a container holding coolant.

[0011] Preferably, the top of the support platform extends upward to form a enclosure structure, and a drain hole is provided on one side of the support platform. The drain hole is connected to a collection tank through a pipe.

[0012] Preferably, a support frame is provided on the support platform on one side of the grinding part, a storage platform is provided at the bottom of the support frame, and an adjustable positioning plate is provided on the top of the support frame above the storage platform.

[0022] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0023] like Figures 1 to 5 As shown, the present invention discloses a grinding device for busbar cylinder production, comprising a support platform 1, a grinding section driven by a grinding motor 2 on the support platform 1, the grinding section including a central main shaft 3, and multiple support plates 4 spaced circumferentially around the outer side of the main shaft 3, with grinding discs 5 mounted on the support plates 4. The grinding discs 5 are detachably connected to the support plates 4 for periodic replacement. The grinding discs 5 and the support plates 4 can be connected by bolts or by sliding with grooves and protrusions. For example, T-shaped protrusions or grooves can be provided at the bottom of the grinding discs 5, and T-shaped grooves or protrusions can be provided at the top of the support plates 4, achieving the connection through sliding. Each support plate 4 and both ends of the main shaft 3 are provided with hinge rods 6, specifically as shown in the figure. Figure 1 and Figure 2 As shown, one end of the support plate 4 is hinged to one side of the main shaft 3 via a hinge rod 6, and the other end of the support plate 4 is hinged to the main shaft 3 via two hinge rods 6. One end of the hinge rod 6 is hinged to a sliding sleeve 7, which is fitted over the main shaft 3. The sliding sleeve 7 is connected to an adjusting screw sleeve 8. The main shaft 3 has external threads, and the adjusting screw sleeve 8 is threadedly connected to the main shaft 3. When the grinding diameter needs to be adjusted, rotating the adjusting screw sleeve 8 will not affect the rotation of the adjusting screw sleeve 8 because the adjusting screw sleeve 8 is rotatably connected to the sliding sleeve 7. As the sliding sleeve 7 moves, it will push the hinge rod 6 up along the hinge point, thereby achieving the purpose of expanding the diameter of the grinding part, expanding the scope of application of this utility model, and enhancing its practicality.

[0024] Furthermore, a receiving sleeve 9 is provided on the support platform 1, and an adjusting rod 10 that can be adjusted axially is provided inside the receiving sleeve 9. The grinding motor 2 is located at the end of the adjusting rod 10. By controlling the adjusting rod 10 to move outward from the receiving sleeve 9, the grinding distance can be extended to meet the grinding operations of busbar cylinders of various lengths. Preferably, a threaded screw 11 is provided inside the receiving sleeve 9. The two ends of the threaded screw 11 are rotatably connected to the two ends of the receiving sleeve 9. The threaded screw 11 is driven by a drive motor located on one side of the receiving sleeve 9. The drive motor and the threaded screw 11 are connected by a coupling. The adjusting rod 10 is provided on the slider 12 of the threaded screw 11, and a through hole is opened at one end of the receiving sleeve 9 for the adjusting rod 10 to move through. Multiple adjusting rods 10 are spaced apart along the circumference of the threaded screw 11. Each adjusting rod 10 extends from the receiving sleeve 9 and is fitted with a fixing sleeve 13. The grinding motor 2 is mounted on the fixing sleeve 13, and is connected to the main shaft 3 via a coupling to ensure transmission accuracy. During operation, the drive motor 25 rotates the threaded screw 11, and the slider 12 moves the adjusting rods 10, causing them to exit the receiving sleeve 9, thereby extending the grinding distance. In this embodiment, the grinding section can initially meet the grinding requirements of the inner wall of the smallest diameter busbar cylinder, and the diameters of the receiving sleeve 9 and the fixing sleeve 13 are not larger than the initial diameter of the grinding section. It is worth noting that the grinding motor and drive motor described in this embodiment are conventional motors commonly used in the prior art; they are simply named differently for distinction.

[0025] In addition, the fixing sleeve 13 is preferably designed as a disc, with an annular accommodating cavity opened along its circumference. The fixing sleeve 13 is provided with a spray hole 14 that communicates with the accommodating cavity, and the spray hole 14 is opened towards the inner wall of the busbar drum. A stretchable bamboo-joint hose 15 is provided on one side of the accommodating cavity. The bamboo-joint hose 15 is connected to a container holding coolant. During operation, the coolant is sprayed onto the inner wall of the busbar drum through the bamboo-joint hose 15 via a delivery pump to achieve the purpose of cooling and lubrication, thus ensuring the polishing effect.

[0026] The top of the support platform 1 extends upward to form a barrier structure 16, which can prevent the spray liquid from dripping to the outside and polluting the working environment. A drain hole is opened on one side of the support platform 1, and the drain hole is connected to a collection tank 17 through a pipe for collecting waste liquid. The collection tank 17 is equipped with a discharge port to facilitate the centralized discharge of waste liquid in the future.

[0027] Furthermore, a support frame 18 is provided on the support platform 1 on one side of the grinding section, and a placement platform 19 is provided at the bottom of the support frame 18 for supporting the busbar drum. A positioning plate 20 that can be adjusted up and down is provided on the top of the support frame 18 above the placement platform 19. The positioning plate 20 is pressed onto the busbar drum to ensure the stability of the busbar drum during the grinding process. The positioning plate 20 can be moved up and down by means of a cylinder or electric push rod on the support frame 18. Preferably, V-shaped positioning grooves 21 are provided on the opposite end faces of the positioning plate 20 and the placement platform 19 to improve the clamping and positioning effect of the busbar drum.

[0028] In addition, the support frame 18 can be slidably adjusted along the length of the support platform 1 so as to drive the busbar cylinder closer to the grinding part. By gradually fitting the grinding cylinder onto the receiving sleeve 9, it can cooperate with the adjusting rod 10 to further compensate for the extended grinding length of the grinding part. In this embodiment, the movement of the support frame 18 can also be achieved by means of a threaded screw and a slider. One side of the support frame 18 is connected to the slider. In order to avoid the coolant from having an adverse effect on the threaded screw, a receiving groove 22 can be opened on the inner side wall of the enclosure structure 16. A motor-driven threaded screw is set in one receiving groove 22, and a guide rod 23 is set in the receiving groove 22 of the other enclosure. A guide block 24 that is slidably connected to the guide rod 23 is set on the support frame 18. The support frame 18 is driven to move closer to or further away from the grinding part under the forward and reverse rotation of the motor.

[0029] In operation, the busbar drum is placed in the positioning groove 21 on the platform 19. Then, the positioning plate 20 is controlled to move down and press against the busbar drum to position it. After that, the diameter of the grinding part is adjusted so that it enters the busbar drum and the grinding block contacts the inner wall of the busbar drum. In the initial state, the grinding part is located at the end of the busbar drum. As the grinding work progresses, the grinding motor 2 can be controlled to push the adjusting rod 10 out of the receiving sleeve 9 by the slider 12. At this time, the grinding part will move inside the busbar drum to complete the grinding operation on the inner wall of the busbar drum. When the adjusting rod 10 is completely removed and there is still part of the inner wall of the busbar drum that has not been ground, the support frame 18 can be controlled to move towards the receiving sleeve 9 to make up for the grinding blind spot and enhance the practicality of the present invention.
