Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of disconnector box assembly equipment, in particular to a docking device for a disconnector box. BACKGROUND

[0002] The disconnector box is an electrical device used in power systems, mainly used for isolating power sources, switching operations, and maintenance safety assurance. The mechanism box and the disconnector spline shaft in the disconnector box are important components of the disconnector box. The mechanism box is the operation and control center of the disconnector, mainly used for installing various operating mechanisms, control elements, transmission devices, etc., to realize the opening and closing operations of the disconnector, and to protect and monitor it. The disconnector spline shaft is a key transmission component connecting the operating mechanism and the moving contact of the disconnector, mainly used for transmitting torque and motion, accurately transmitting the power of the operating mechanism to the moving contact in the mechanism box, so that the moving contact can perform opening and closing actions as required.

[0003] In the assembly process of the disconnector box, the mechanism box and the disconnector spline shaft need to be assembled. Specifically, the spline hole on the mechanism box needs to be aligned and inserted with the center axis of the disconnector spline shaft. However, in the related art, only the problem of aligning the spline hole on the mechanism box with the center axis of the disconnector spline shaft can be solved, but the problem of aligning the spline hole on the mechanism box with the center axis spline groove of the disconnector spline shaft cannot be solved, resulting in the inability to realize the automatic assembly of the mechanism box and the disconnector spline shaft. SUMMARY

[0004] The present application aims to solve one of the technical problems in the related art to some extent. To this end, the present application provides a docking device for a disconnector box.

For those skilled in the art, the specific meaning of the above-mentioned terms in the present application can be understood according to the specific circumstances.

[0038] The present embodiment provides a docking device for isolating switch box, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the docking device is used for aligning and inserting the spline hole of the mechanism box 8 with the isolating switch spline shaft, and the docking device comprises a fixed seat 1, a movable plate 2, a clamping assembly 3 and a locking assembly 4. Wherein, the fixed seat 1 is configured to be able to rotate around the center axis of the spline hole in response to external force, and the movable plate 2 is arranged on the fixed seat 1. The movable plate 2 has a locking state capable of keeping stable relative to the fixed seat 1 and an unlocking state capable of moving relative to the fixed seat 1 in a first direction. The locking assembly 4 is arranged between the movable plate 2 and the fixed seat 1 and is used for switching the movable plate 2 between the locking state and the unlocking state. The clamping assembly 3 is arranged on the movable plate 2 and can clamp and fix the mechanism box 8 relative to the movable plate 2 and release and separate. The first direction is the direction of the mechanism box 8 pointing to the isolating switch spline shaft, that is Figure 2 the direction from top to bottom as indicated by the arrow P in the middle.

[0039] The locking assembly 4 can switch the movable plate 2 to the locked state, in which the fixed seat 1 is moved to the mechanism box 8 by the movable plate 2 and the clamping assembly 3, so that the spline hole on the mechanism box 8 is aligned with the center axis of the disconnecting switch spline shaft. Then, the locking assembly 4 can switch the movable plate 2 to the unlocked state, and the fixed seat 1 is rotated around the center axis of the spline hole, so that the movable plate 2 and the mechanism box 8 clamped and fixed by the clamping assembly 3 on the movable plate 2 are synchronously rotated. Since the movable plate 2 can move in the first direction relative to the fixed seat 1, when the mechanism box 8 is rotated to the spline groove of the disconnecting switch spline shaft, the mechanism box 8 and the movable plate 2 can automatically fall under the action of their own gravity, realizing the automatic plug-in assembly of the mechanism box 8 and the disconnecting switch spline shaft.

[0040] In combination with Figure 1 , Figure 6 and Figure 7 , the locking assembly 4 in the embodiment includes a first driving mechanism 40 and a support block 41. The support block 41 is connected with the output end of the first driving mechanism 40 and can be switched between the first position and the second position under the driving of the first driving mechanism 40. When the support block 41 is located at the first position, it is in abutment with the fixed seat 1 and the movable plate 2 respectively, so that the movable plate 2 is in the locked state. When the support block 41 is located at the second position, it is separated from one of the fixed seat 1 and the movable plate 2, so that the movable plate 2 is in the unlocked state. In the embodiment, the locking assembly 4 is arranged on the movable plate 2, and when the support block 41 is located at the second position, it is spaced apart from the fixed seat 1, that is, the support block 41 is separated from the fixed seat 1 when it is located at the second position.

[0041] In combination with Figure 8 and Figure 9 , the locking assembly 4 in the embodiment further includes a guide structure arranged between the movable plate 2 and the fixed seat 1. Specifically, the guide structure includes a guide shaft 42 extending in the first direction and a limiting piece 43 arranged at the lower end of the guide shaft 42. The top end of the guide shaft 42 is fixedly connected with the fixed seat 1, the guide shaft 42 passes through the movable plate 2 and is in sliding fit with the movable plate 2, and the limiting piece 43 is located below the movable plate 2 and is used to limit the disengagement of the movable plate 2 and the guide shaft 42. In this way, when the first driving mechanism 40 drives the support block 41 to move to the first position, the support block 41 exerts an upward pressure on the fixed seat 1 and an downward pressure on the movable plate 2. Since the top end of the guide shaft 42 is fixedly connected with the fixed seat 1 and the lower end of the guide shaft 42 passes through the movable plate 2 and is provided with the limiting piece 43, the movable plate 2 can reach the maximum distance relative to the fixed seat 1, so that the two are kept relatively fixed. When the first driving mechanism 40 drives the support block 41 to move to the second position, the support block 41 is separated from the fixed seat 1, and the movable plate 2 can slide relative to the fixed seat 1 along the guide shaft 42.

[0042] The assembly process of the movable plate 2, the fixed seat 1 and the guide structure in the embodiment is explained as follows: the top end of the guide shaft 42 is fixed to the fixed seat 1 by screw locking, the movable plate 2 is provided with a through hole, the lower end of the guide shaft 42 passes through the through hole, and then the limiting piece 43 is fixed and installed at the lower end of the guide shaft 42 by screw, and the limiting piece 43 in the embodiment is a circular plate with a diameter larger than that of the guide shaft 42. In addition, a bushing 44 can also be arranged between the guide shaft 42 and the through hole before the limiting piece 43 is installed, and the bushing 44 is locked and fixed to the movable plate 2 by the rim at the bottom. The arrangement of the bushing 44 can make the sliding of the guide shaft 42 relative to the through hole more smooth.

[0043] In combination with the figures shown in Figure 3 , Figure 4 and Figure 5 , the process of using the docking device to automatically assemble the mechanism box 8 and the disconnecting switch spline shaft is explained as follows:

[0044] Figure 3 The state of clamping and fixing the mechanism box 8 to the movable plate 2 by using the docking device provided in the embodiment is shown in Figure 4 . At this time, the locking assembly 4 makes the movable plate 2 in a locked state, that is, the supporting block 41 is at the first position, so that the fixed seat 1 drives the mechanism box 8 to move to the state that the spline hole on the mechanism box 8 is aligned with the center axis of the disconnecting switch spline shaft through the movable plate 2 and the clamping assembly 3. After the spline hole on the mechanism box 8 is aligned with the center axis of the disconnecting switch spline shaft, the fixed seat 1 is controlled to move downward to obtain the state shown in Figure 4 . At this time, since the keyway of the spline hole on the mechanism box 8 is not aligned with the keyway of the disconnecting switch spline shaft, the disconnecting switch spline shaft can support the mechanism box 8, so the guide shaft 42 can move downward with the fixed seat 1 during the downward movement of the fixed seat 1. That is, at this time, the supporting block 41 is at the second position, and the movable plate 2 is in an unlocked state. Then, the fixed seat 1 is driven to rotate around the center axis of the spline shaft, which can drive the movable plate 2 and the isolation box clamped and fixed to the movable plate 2 by the clamping assembly 3 to rotate synchronously. It is easy to understand that after the isolation box rotates by a certain angle, the keyway of the spline hole on the lower surface of the isolation box can be aligned with the keyway of the disconnecting switch spline shaft, and under the action of the self-gravity of the mechanism box 8 and the movable plate 2, the mechanism box 8 and the movable plate 2 can automatically fall down to realize the automatic assembly of the mechanism box 8 and the disconnecting switch spline shaft. Then, the clamping assembly 3 is controlled to release the clamping and fixing of the mechanism box 8, so that the docking device and the mechanism box 8 are separated, and the state shown in Figure 5 is obtained.

[0045] The first driving mechanism 40 in the embodiment is a linear driver arranged on the movable plate 2. The support block 41 is connected with the output end of the first driving mechanism 40 and is slidingly arranged on the movable plate 2. A docking protrusion 10 is formed below the fixed seat 1. A guide slope is arranged between the support block 41 and the docking protrusion 10 to guide the support block 41 to extend below the docking protrusion 10. The support block 41 extends below the docking protrusion 10 and abuts against the docking protrusion 10 when the support block 41 is at the first position. The support block 41 is separated from the docking protrusion 10 when the support block 41 is at the second position. In combination Figure 2 As shown in FIG. 1, to ensure the stability of the sliding of the support block 41, a first sliding rail 20 is arranged on the movable plate 2 in the embodiment. The support block 41 is slidingly arranged on the first sliding rail 20. In addition, a first guide slope 100 in the form of a plane is arranged on the docking protrusion 10. A second guide slope 410 in the form of a plane is arranged on the support block 41. The first guide slope 100 and the second guide slope 410 cooperate with each other.

[0046] It should be noted that the first driving mechanism 40 in the embodiment is a linear driver. The first driving mechanism 40 drives the support block 41 to slide in the horizontal direction so that the support block 41 is switched between the first position and the second position. In other alternative embodiments, a driving motor can be used as the first driving mechanism 40. The first driving mechanism 40 drives the support block 41 to be switched between the first position and the second position through a rotating action. Specifically, as shown in FIG. 2, in this kind of embodiment, the support block 41 is in the form of a plate. The lower surface of the docking protrusion 10 is provided with a first guide slope 100 in the form of an arc. One end of the support block 41 is provided with a second guide slope 410 in the form of an arc. The first guide slope 100 and the second guide slope 410 cooperate with each other. Figure 10 The first driving mechanism 40 drives the support block 41 to rotate. When the support block 41 is rotated to a vertical state (i.e., the support block 41 is located at the first position), the support block 41 can abut against the docking protrusion 10. When the support block 41 is rotated to a horizontal position (i.e., the support block 41 is located at the second position), the support block 41 can be separated from the fixed seat 1. The effect that can be achieved by the driving assembly in the present application can also be achieved. Figure 10

[0047] In addition, the wire guide structure in the embodiment is provided with four groups. The four groups of guide structures cooperate with each other to limit the movable plate 2 from shaking along the circumferential direction of the guide shaft 42 relative to the fixed seat 1. It should be understood that in other alternative embodiments, the guide structure can also be provided with two groups or more.

[0048] ​As previously described, the clamping assembly 3 and locking assembly 4 in this embodiment are both disposed on the movable plate 2. When the keyway of the spline hole in the isolation box aligns with the keyway of the isolating switch spline shaft, the mechanism box 8, movable plate 2, clamping assembly 3, and locking assembly 4 as a whole move downward relative to the fixed base 1. Due to the heavy weight of the mechanism box 8, movable plate 2, clamping assembly 3, and locking assembly 4, they may experience a relatively violent rigid collision with the isolating switch spline shaft, potentially causing damage to the mechanism box 8 or the isolating switch spline shaft. To this end, the docking device provided in this embodiment also includes an elastic member 5 disposed between the fixed base 1 and the movable plate 2. The elastic member 5 applies pressure to the movable plate 2 and the fixed base 1, causing the movable plate 2 and the fixed base 1 to move closer to each other. Specifically, the elastic member 5 in this embodiment is a tension spring, one end of which is fixed to the fixed base 1 and the other end of which is fixed to the movable plate 2. It is easy to understand that the force applied by the elastic member 5 on the movable plate 2 is less than the weight of the mechanism box 8.

[0049] By providing the elastic member 5, an upward pulling force can be applied to the mechanism box 8 during the falling process, thereby reducing the rigid collision force between the mechanism box 8 and the isolating switch spline shaft, avoiding damage to the mechanism box 8 and the isolating switch spline shaft.

[0050] As mentioned above, when the docking device is used to assemble the mechanism box 8 and the spline shaft of the disconnector, it is necessary to control the fixed seat 1 to rotate. For this purpose, the docking device provided in this embodiment also includes a mechanical arm (not shown in the figure), which is fixedly connected to the fixed seat 1 and can drive the fixed seat 1 to rotate around the central axis of the spline hole at a set speed. Specifically in this embodiment, the set speed is 2r / min, that is, the fixed seat 1 is controlled to rotate at a speed of two revolutions per minute. Of course, according to different keyway specifications, the set speed can be a selected value between 0.5r / min and 3r / min. As Figure 1 As shown, a robotic arm coupler 7 for docking with a robotic arm is provided on the upper portion of the fixed base 1. In addition, the robotic arm in this embodiment is a six-axis robotic arm, which can not only drive the fixed base 1 to rotate around the central axis of the spline shaft, but also drive the fixed base 1 to move horizontally and vertically. In this way, when the movable plate 2 is in a locked state, the fixed base 1, the movable plate 2, and the mechanism box 8 can be driven by the robotic arm to move horizontally, so as to drive the mechanism box 8 to move until the spline hole on the mechanism box 8 is aligned with the spline shaft of the disconnector. It is also possible to drive the fixed base 1 and the guide shaft 42 downward relative to the movable plate 2 when the movable plate 2 is in an unlocked state, so that the movable plate 2 can float relative to the fixed base 1.

[0051] Further, the docking device provided by the embodiment further comprises a detection element (not shown in the figure), the detection element is electrically connected with the mechanical arm and the clamping assembly 3, and the detection element is used for detecting the relative position change information between the fixed seat 1 and the movable plate 2. Specifically, the detection element in the embodiment is a position sensor. When the mechanism box 8 is automatically aligned with the key groove of the disconnecting switch spline shaft through rotation of the mechanism box 8, the mechanism box 8 moves downward under the action of gravity, so that the spline shaft is inserted into the spline hole. The position change of the movable plate 2 following the downward movement of the mechanism box 8 can be detected by the detection element, so that it can be judged that the mechanism box 8 has completed the docking insertion with the disconnecting switch spline shaft. The working of the mechanical arm and the clamping assembly 3 can be controlled according to the information detected by the detection element. It is easy to understand that the detection element can be arranged on the fixed seat 1 or the movable plate 2.

[0052] In addition, as shown in Figure 1 and Figure 2 The clamping assembly 3 in the embodiment comprises a second driving mechanism 30 arranged on the movable plate 2 and a clamp 31 connected with the second driving mechanism 30, and the clamp 31 can be docked with and separated from the mechanism box 8 under the driving of the second driving mechanism 30. Specifically, the clamp 31 can be a pneumatic clamp jaw, and the clamp 31 can move in the horizontal direction under the driving of the second driving mechanism 30, so that the clamp 31 can be docked with and separated from the edge of the mechanism box 8. After the clamp 31 is docked with the edge of the mechanism box 8, the clamp 31 can automatically clamp the edge of the mechanism box 8, and lock the mechanism box 8 on the movable plate 2. In order to improve the stability of the clamp 31 moving in the horizontal direction, the second sliding rail 21 is arranged on the lower surface of the movable plate 2 in the embodiment, and the clamp 31 is slidingly arranged on the second sliding rail 21.

[0053] Further, the docking device further comprises a positioning shaft 6 fixedly arranged on the movable plate 2, and a positioning protrusion 60 is arranged at the lower end of the positioning shaft 6 and used for movably inserting into the mechanism box 8. The positioning shaft 6 and the positioning protrusion 60 can facilitate the docking of the docking device and the mechanism box 8. Specifically, in the initial assembly stage, the positioning protrusion 60 is first inserted into the corresponding positioning hole on the mechanism box 8 by driving the fixed seat 1 to move by the mechanical arm, and then the mechanism box 8 is locked and fixed on the movable plate 2 by the clamping assembly 3.

[0054] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Those skilled in the art should understand that the present application includes but is not limited to the contents described in the above specific embodiments and the drawings. Any modification without deviating from the functional and structural principles of the present application shall be included in the scope of the claims.
