Description

Technical Field

[0001] The present invention relates to the technical field of robot structures, in particular to a grounding switch positioning mechanism with visual component centering and telescopic function. Background Art

[0002] As the number of substations increases, the number of switchgear equipment also increases accordingly, and the demand for operation and maintenance personnel increases. However, at present, substation operation and maintenance is mainly based on manual inspection and operation. As the number of substations increases, the man-station ratio decreases, resulting in increased workload for operation and maintenance personnel, low work efficiency, and increased safety risks.

[0003] Currently, switchgear grounding switches are mostly operated manually, using a handle to manually crank the switch operating head. Operators must use both hands to depress the pressure plate and insert the handle, requiring a high level of operator expertise. Some existing robots can be equipped with grounding switch operating mechanisms to replace manual switching operations. However, these robots struggle to accurately position the rotating sleeve relative to the operating head during switchgear operation, resulting in a low success rate.

[0004] In order to smoothly complete the switching operation of the switch cabinet, the present invention designs a grounding knife switch positioning mechanism with visual component centering and telescopic function, which is installed on the operating robot so that it can accurately complete the positioning of the rotating sleeve and the switch cabinet knife switch operating head when switching, laying a good foundation for the next step of rotating the knife switch. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides an earthing knife switch positioning mechanism with visual component centering and telescopic function, which has the advantages of accurate positioning and high operation success rate. It solves the problem that the robot cannot accurately position the rotating sleeve relative to the operating head when operating the switch cabinet knife switch and the operation success rate is low.

[0006] In order to achieve the above-mentioned accurate positioning and high operation success rate, the present invention provides the following technical solutions: a grounding knife switch positioning mechanism with visual component centering and telescopic function, comprising a rotating operating rod, a connecting piece, a visual fixing component and a rotating sleeve, one side of the rotating operating rod is inserted into the interior of the connecting piece, one side of the connecting piece is fixedly connected to one side of the rotating sleeve by a screw, the visual fixing component is located inside the rotating sleeve, a camera is provided inside the visual fixing component, the camera positions the rotating sleeve in real time, a bearing is sleeved inside the rotating sleeve, a fixing rod is provided inside the rotating operating rod, one side of the fixing rod is fixedly connected to a compression spring limit seat, a compression spring is installed inside the compression spring limit seat, one side of the compression spring is sleeved with a positioning rod, and the outer surface of the positioning rod is threadedly connected to the interior of the visual fixing component.

[0007] Preferably, the inner surface of the bearing is sleeved on the outer surface of the positioning rod, and the outer surface of the bearing is sleeved on the inside of the rotating sleeve. The positioning rod is rotatably connected to the rotating sleeve through the bearing to ensure that the camera does not rotate with the rotating sleeve.

[0008] Preferably, a retaining ring is fixedly connected to the outside of the positioning rod, one side of the retaining ring is overlapped with one side of the bearing, and the other side of the retaining ring is fixedly connected to one side of the compression spring, and the bearing is maintained without relative displacement in the axial direction of the rotating sleeve by the compression spring.

[0009] Preferably, the connecting member is used to realize a floating connection between the rotating sleeve and the rotating operating rod, so that the rotating sleeve and the rotating operating rod can swing along the axis deviation direction, and the rotating sleeve and the rotating operating rod rotate synchronously.

[0010] Preferably, the connecting member adopts a flexible coupling, so that the rotating sleeve and the rotating operating rod can obtain a floating amount of expansion and contraction in the axial direction and swing in any direction away from the axis.

[0011] Preferably, the retaining ring is maintained without relative displacement in the axial direction of the rotating sleeve by a compression spring, thereby ensuring that the camera and the rotating sleeve can be extended and retracted together.

[0012] Preferably, the rotary operating rod adopts a spline shaft structure for transmission, and the inner portion of the connecting member is fixedly connected to the outer surface of the rotary operating rod.

[0013] Preferably, the interiors of the fixing rod and the positioning rod are both hollow structures, capable of accommodating the connecting wire of the camera.

[0014] Compared with the prior art, the present invention provides a grounding switch positioning mechanism with visual component centering and telescopic function, which has the following beneficial effects:

[0015] The connecting piece in the grounding knife switch positioning mechanism with visual component centering and telescopic function adopts a flexible coupling structure, which can realize a floating connection between the rotating sleeve and the rotating operating rod, and can deflect by its own flexibility when there is a small deviation between the rotating sleeve and the switch cabinet knife switch operating head, so as to facilitate smooth connection between the rotating sleeve and the switch cabinet knife switch operating head, effectively improving the docking success rate of the rotating sleeve and the switch cabinet knife switch operating head, and has a simple structure and low cost. The camera and the rotating sleeve are connected by a bearing to ensure that the camera does not rotate when the rotating sleeve rotates, and the bearing is maintained without relative displacement in the axial direction of the rotating sleeve by a compression spring, thereby ensuring that the camera and the rotating sleeve can be extended and retracted together, which can ensure the positioning accuracy of the knife switch operating head, thereby more accurately guiding the robot to adjust its posture, further improving the docking success rate of the rotating sleeve and the switch cabinet knife switch operating head, and enabling the robot to complete the knife switch opening and closing action more smoothly.

[0021] See also Figure 1-4, a grounding knife switch positioning mechanism with visual component centering and telescopic, including a rotating operating rod 1, a connecting part 2, a visual fixing part 3 and a rotating sleeve 4, one side of the rotating operating rod 1 is inserted into the interior of the connecting part 2, and one side of the connecting part 2 is fixedly connected to one side of the rotating sleeve 4 by a screw, the visual fixing part 3 is located inside the rotating sleeve 4, and a camera 5 is provided inside the visual fixing part 3. The camera 5 locates the rotating sleeve 4 in real time, and then controls the robot to adjust its posture, thereby ensuring that the rotating sleeve 4 and the operating head cooperate smoothly during operation, so that the operating robot can successfully complete the switch cabinet knife switch work, a bearing 6 is sleeved inside the rotating sleeve 4, a fixing rod 9 is provided inside the rotating operating rod 1, one side of the fixing rod 9 is fixedly connected to a compression spring limit seat 8, a compression spring 7 is installed inside the compression spring limit seat 8, and a positioning rod 10 is sleeved on one side of the compression spring 7, and the outer surface of the positioning rod 10 is threadedly connected to the interior of the visual fixing part 3, and the visual fixing part 3 is used to fix the camera 5.

[0022] The inner surface of the bearing 6 is sleeved on the outer surface of the positioning rod 10, and the outer surface of the bearing 6 is sleeved on the inside of the rotating sleeve 4. The positioning rod 10 is rotatably connected to the rotating sleeve 4 through the bearing 6 to ensure that the camera 5 does not rotate with the rotating sleeve 4. A regular hexagonal groove is provided on one side of the rotating sleeve 4, and a chamfer is provided at the edge of the regular hexagonal groove (the structure is relatively simple, not shown in the figure, and technical personnel can implement it according to the plan) to facilitate cooperation with the switch cabinet knife switch operating head.

[0023] A retaining ring 11 is fixedly connected to the outside of the positioning rod 10. One side of the retaining ring 11 overlaps one side of the bearing 6, and the other side of the retaining ring 11 is fixedly connected to one side of the compression spring 7. The bearing 6 is maintained without relative displacement in the axial direction of the rotating sleeve 4 through the compression spring 7.

[0024] The connecting member 2 is used to realize a floating connection between the rotating sleeve 4 and the rotating operating rod 1, so that the rotating sleeve 4 and the rotating operating rod 1 can swing along the axis deviation direction, and the rotating sleeve 4 and the rotating operating rod 1 rotate synchronously.

[0025] The connecting member 2 adopts a flexible coupling, so that the rotating sleeve 4 and the rotating operating rod 1 can obtain axial expansion and contraction and floating amount of swinging in any direction away from the axis, which can make the rotating sleeve 4 smoothly connected and matched even when there is a small deviation between the operating head, and the fixed rod 9 and the positioning rod 10 are connected by a compression spring 7, which can make the positioning rod 10 deviate with the rotating sleeve 4 when the rotating sleeve 4 deviates, and the matching bearing 6 deviates with it, thereby allowing the camera 5 to deviate accordingly.

[0026] The retaining ring 11 is kept without relative displacement in the axial direction of the rotating sleeve 4 by the compression spring 7, thereby ensuring that the camera 5 and the rotating sleeve 4 can be extended and retracted together. The compression spring 7 always pushes the retaining ring 11, thereby ensuring that no axial displacement occurs between the bearing 6 and the rotating sleeve 4, thereby ensuring that the camera 5 and the rotating sleeve 4 can be extended and retracted together.

[0027] The rotary operating rod 1 is driven by a spline shaft structure, and the interior of the connecting member 2 is fixedly connected to the outer surface of the rotary operating rod 1 .

[0028] The interiors of the fixing rod 9 and the positioning rod 10 are both hollow structures, which can accommodate the connecting wires of the camera 5. This arrangement facilitates the placement of the connecting wires of the camera 5, and prevents the connecting wires from rotating and causing damage to them when the rotating operating rod 1, the connecting piece 2 and the rotating sleeve 4 rotate.

[0029] During the operation of the switch cabinet knife switch, the rotating operating rod 1 and one side of the fixed rod 9 are connected to the robot, the camera 5 detects and locates the position of the switch cabinet knife switch operating head, and feeds back the detection result to the robot. When there is an offset between the rotating sleeve 4 and the operating head, the rotating sleeve 4 swings in the direction of axis deviation. The present invention locates the hexagonal surface of the rotating sleeve 4 in real time through the camera, and then controls the robot to adjust the posture, thereby ensuring the smooth cooperation between the rotating sleeve 4 and the operating head during the operation. Then, after the rotating sleeve 4 is sleeved on the switch cabinet knife switch operating head, the connection is completed, and the robot drives the rotating operating rod 1 to rotate, so that the operating robot can smoothly complete the switch cabinet knife switch operation and perform the switching operation.

[0030] In summary, the connector 2 in the grounding knife switch positioning mechanism with visual component centering and telescopic function adopts a flexible coupling structure to achieve a floating connection between the rotating sleeve 4 and the rotating operating rod 1. When there is a small deviation between the rotating sleeve 4 and the switch cabinet knife switch operating head, it can deflect through its own flexibility to facilitate smooth connection between the rotating sleeve 4 and the switch cabinet knife switch operating head, effectively improving the docking success rate of the rotating sleeve 4 and the switch cabinet knife switch operating head, and the structure is simple and the cost is low. The camera 5 and the rotating sleeve 4 are connected by a bearing 6 to ensure that the camera 5 does not rotate when the rotating sleeve 4 rotates, and the bearing 6 is maintained without relative displacement in the axial direction of the rotating sleeve 4 by the compression spring 7, thereby ensuring that the camera 5 and the rotating sleeve 4 are telescoped together, which can ensure the positioning accuracy of the knife switch operating head, thereby more accurately guiding the robot to adjust its posture, further improving the docking success rate of the rotating sleeve 4 and the switch cabinet knife switch operating head, and enabling the robot to complete the knife switch opening and closing action more smoothly.
