Technical Field

[0001] The utility model relates to the technical field of high-voltage cabinets, in particular to a high-voltage cabinet operation robot for a coal preparation plant. Background Technique

[0002] A coal preparation plant is used to separate coal, remove mineral impurities in raw coal, and divide it into coal products of different specifications. Due to the high working intensity, many tasks have been replaced by machines, and an intelligent coal preparation plant has become the development direction of coal preparation plants. The intelligent high-voltage cabinets currently in use operate through a 10kV high-voltage system and are equipped with a communication background system;

[0003] For the traditional high-voltage cabinet, the opening and closing of the circuit breaker are generally carried out after closing the door. An operating rod is inserted into the door to operate the circuit breaker. Operating in a narrow space is inconvenient, and it is easy to have problems such as misalignment, which is rather troublesome. Moreover, the operating rod is taken out only when in use and is placed aside usually, so it is easy to be lost, making it difficult to automatically or manually control the opening and closing of the circuit breaker.

[0006] A high-voltage cabinet operation robot for a coal preparation plant includes a cabinet body. A circuit breaker is installed inside the cabinet body. Two sliding plates are arranged outside the knife switch in the middle of the circuit breaker. The two sliding plates are rotationally connected by two pressing rollers. The bottom ends of the two sliding plates are fixedly connected with a toothed plate. A transmission gear is meshed with the outer wall of the toothed plate. An L-shaped connecting plate is fixedly installed on the side wall of the sliding plate away from the pressing roller. A limiting plate is arranged at the bottom of the L-shaped connecting plate. A sliding groove is opened on the outer wall of the limiting plate, and the sliding groove is slidably matched with the bottom end of the L-shaped connecting plate.

[0007] Further, a movable groove is opened on the outer wall of the cabinet body. The transmission gear is rotationally connected with the inner wall of the movable groove. A driven gear is meshed with the outer wall of the transmission gear. A spline shaft is fixedly connected to the center of the driven gear.

[0008] Further, a first spline sleeve and a second spline sleeve are slidably arranged at both ends of the spline shaft respectively. A driving motor is fixedly arranged at one end of the second spline sleeve.

[0009] Further, the drive motor is fixedly connected to one side wall of the movable slot, the first spline sleeve is rotatably fitted with the other side wall of the movable slot, a limiting sleeve is slidably arranged on the outer wall of the spline shaft, a mounting rod is rotatably arranged at the bottom end of the limiting sleeve, and the bottom end of the mounting rod is fixedly connected to the movable slot.

[0021] Embodiment 1:

[0022] As Figures 1-4 shown, a high-voltage cabinet operation robot for a coal preparation plant proposed in this embodiment includes a cabinet body 1. A circuit breaker 2 is installed inside the cabinet body 1. Two sliding plates 9 are arranged outside the knife switch 3 in the middle of the circuit breaker 2. The two sliding plates 9 are rotatably connected by two pressing rollers 8. The bottom ends of the two sliding plates 9 are fixedly connected with a toothed plate 10. A transmission gear 20 is meshed with the outer wall of the toothed plate 10. An L-shaped connecting plate 7 is fixedly installed on the side wall of the sliding plate 9 away from the pressing roller 8. A limiting plate 6 is arranged at the bottom of the L-shaped connecting plate 7. A slideway 11 is opened on the outer wall of the limiting plate 6. The slideway 11 is slidably matched with the bottom end of the L-shaped connecting plate 7.

[0023] A movable groove 12 is opened on the outer wall of the cabinet body 1. The transmission gear 20 is rotatably connected with the inner wall of the movable groove 12. A driven gear 14 is meshed with the outer wall of the transmission gear 20. A spline shaft 19 is fixedly connected to the center of the driven gear 14; when the driving motor 17 rotates forward, the driven gear 14 drives the transmission gear 20 to rotate, so that the transmission gear 20 meshes with the toothed plate 10, moves the toothed plate 10 downward, and thus drives the two sliding plates 9 to move downward. After the sliding plates 9 are limited by the limiting plate 6 and move downward, the pressing roller 8 is pushed downward to push the knife switch 3, so that the circuit breaker 2 is turned on.

[0024] The two ends of the spline shaft 19 are respectively slidably provided with a first spline sleeve 16 and a second spline sleeve 18. A driving motor 17 is fixedly arranged at one end of the second spline sleeve 18.

[0025] The driving motor 17 is fixedly connected to one side wall of the movable groove 12. The first spline sleeve 16 is rotationally matched with the other side wall of the movable groove 12 through a bearing. A limiting sleeve is slidably arranged on the outer wall of the spline shaft 19. The bottom end of the limiting sleeve is rotatably provided with a mounting rod 15, and the bottom end of the mounting rod 15 is fixedly connected to the movable groove 12. Pull the spline shaft 19 to move the side of the spline shaft 19 away from the driving motor 17 into the first spline sleeve 16, and then rotate the driven gear 14 to control the upward or downward movement of the toothed plate 10, thereby realizing the opening and closing of the circuit breaker 2.

[0026] Two L-shaped fixing rods 5 are fixedly arranged at the bottom end of the limiting plate 6. The two L-shaped fixing rods 5 are arranged in opposite directions. One end of the L-shaped fixing rod 5 is fixedly installed with a fixing plate 4, and a threaded hole is formed on the outer wall of the fixing plate 4. During installation, align the fixing plate 4 with the threaded hole on the circuit breaker 2, and at the same time install the two limiting plates 6 on its outer side, which is convenient for installation.

[0027] The working process and principle of the present utility model are as follows:

[0028] Automatically control the switch of the circuit breaker 2:

[0029] Opening: The driving motor 17 rotates forward to drive the driven gear 14 to drive the transmission gear 20 to rotate, so that the transmission gear 20 meshes with the toothed plate 10, moves the toothed plate 10 downward, thereby driving the two sliding plates 9 to move downward. After the sliding plates 9 are limited by the limiting plates 6 and move downward, the pressing roller 8 is pushed downward to push the knife switch 3, so that the circuit breaker 2 is opened;

[0030] Closing: Control the driving motor 17 to rotate in the reverse direction, so that the lower pressing roller 8 pushes the knife switch 3 upward to close the circuit breaker 2, thereby automatically completing the opening and closing of the circuit breaker 2;

[0031] Manually control the switch of the circuit breaker 2:

[0032] Pull the spline shaft 19 to move the side of the spline shaft 19 away from the driving motor 17 into the first spline sleeve 16, and then rotate the driven gear 14 to control the upward or downward movement of the toothed plate 10, thereby realizing the opening and closing of the circuit breaker 2.
