Description

Technical Field

[0001] This invention relates to the field of busbar arrangement, and more particularly to a busbar support device. Background Technology

[0002] Gas-insulated metal-enclosed switchgear is widely used in the protection and control of power systems, and it is often connected to other electrical equipment via busbars. The layout of switchgear and electrical equipment varies greatly, and conventional busbars such as straight or right-angle types cannot meet the connection requirements of complex power plant electrical equipment. Therefore, to adapt to the diversity of power plant layouts, irregularly shaped busbars with different bending angles have been designed.

[0003] However, existing busbar support devices typically have multiple support seats, which are spaced apart along the length of the busbar. As a result, when using non-standard busbars, different support seats must be used or the support seats must be placed at different heights to adapt to the shape of the non-standard busbar, which is complicated and time-consuming. Summary of the Invention

[0004] The purpose of this invention is to provide a busbar support device to solve the problem that existing busbar support devices require multiple adjustments to adapt to the shape of irregular busbars, which is complicated, time-consuming and labor-intensive.

[0005] To solve the above-mentioned technical problems, the busbar support device of the present invention adopts the following technical solution: The busbar support device includes a horizontal support, on which a pitch support is connected. A pitch adjustment device is provided between the pitch support and the horizontal support. The pitch adjustment device includes a gear reduction mechanism fixed on the horizontal support. The output shaft of the gear reduction mechanism is fixedly connected to the pitch swing shaft of the pitch support. A pitch angle positioning mechanism is also provided between the pitch support and the horizontal support. The pitch angle positioning mechanism includes a support rack connected to one of the pitch support and the horizontal support and a support stop pin connected to the other.

[0006] Furthermore, the support rack is oscillatingly engaged with the pitch support or horizontal support to which it is located, and the swing axis of the support rack is parallel to the pitch swing axis of the pitch support.

[0007] Furthermore, the upper surface of each tooth on the support rack is a sliding surface. When the pitch support is tilted up, the support rack automatically passes over the support stop pin under the action of the sliding surface.

[0008] Furthermore, when the pitch angle of the pitch support is greater than 0 degrees, the connection point between the support rack and the pitch support is located on the side of the support stop pin closer to the pitch axis, and the support rack can automatically swing towards the support stop pin under the action of gravity.

[0009] Furthermore, the supporting rack is an arc-shaped rack.

[0010] Furthermore, the support rack is an arc-shaped rack and is fixedly fitted with the pitch support or horizontal support to which it is located, and the swing axis of the support rack is parallel to the pitch swing axis, and the support stop pin is detachably connected with the pitch support or horizontal support to which it is located.

[0011] Furthermore, a base support for supporting and positioning the supported busbar is provided on the pitch support, and the base support is adjustablely installed on the pitch support along the length direction of the pitch support.

[0012] Furthermore, a connecting sleeve is provided at the connection between the pitch support and the horizontal support. The pitch pivot is rotatably mounted on the horizontal support and its inner end is inserted into the connecting sleeve. Anti-rotation pins are cross-inserted on the pitch pivot, and anti-rotation grooves that cooperate with the anti-rotation pins are provided on the corresponding ends of the connecting sleeve.

[0013] Furthermore, the horizontal support includes a pitch support pillow located at one end of the horizontal support, and the pitch angle positioning mechanism is located at the pitch support pillow.

[0014] Furthermore, wheels are installed on the horizontal support.

[0015] This invention proposes a novel technical solution. By setting up a pitch adjustment mechanism (i.e., a gear reduction mechanism) and a pitch angle positioning mechanism, the angle between the pitch support and the horizontal support can be adjusted, so that the busbar support device can adapt to the shape of irregular busbars and support them. Furthermore, the gear reduction mechanism obtains a larger torque output, and the pitch angle of the pitch support can be adjusted with a smaller force. The operation is simple and saves time and effort. Attached Figure Description

[0018] This invention proposes a novel technical solution to address the problems existing in the above-mentioned technical solutions. The core concept of this invention is to adjust the angle between the pitch support and the horizontal support by setting a pitch adjustment mechanism (i.e., a gear reduction mechanism) and a pitch angle positioning mechanism, so that the busbar support device can adapt to the shape of the irregular busbar to support it. Moreover, the gear reduction mechanism obtains a larger torque output, and the pitch angle of the pitch support can be adjusted by applying a small force. The operation is simple, time-saving and labor-saving.

[0019] Based on the above inventive concept, the basic scheme of a busbar support device of the present invention is as follows: The busbar support device includes a horizontal support 1, on which a pitch support 2 is connected. Both the horizontal support 1 and the pitch support 2 can be used to support the busbar. A pitch adjustment device 3 is provided between the pitch support 2 and the horizontal support 1. The pitch adjustment device includes a gear reduction mechanism 3 fixed to the horizontal support 1, and the output shaft of the gear reduction mechanism 3 is fixedly connected to the pitch swing shaft 8 of the pitch support 2. In this embodiment, the gear reduction mechanism 3 is a planar gear mechanism, which includes, for example, a planar gear mechanism. Figure 3The driving wheel 31 and driven wheel 32 shown have fewer teeth on the driving wheel 31 than on the driven wheel 32, thus forming a gear reduction mechanism 3. When the input shaft 311 of the driving wheel 31 rotates a certain angle, the driven wheel 32 rotates at a smaller angle than the driving wheel 31, and the pitch support 2 also rotates at a smaller angle, achieving speed reduction of the output shaft 321. Simultaneously, the gear reduction mechanism 3 provides a larger torque output for the pitch support 2, allowing for adjustment of the pitch angle of the pitch support 2 with a smaller force. This operation is simple, time-saving, and labor-saving. In use, rotating the input shaft 311 of the driving wheel 31 drives the driven wheel 32 to rotate, causing the output shaft 321 of the driven wheel to rotate as well. This causes the pitch pivot shaft 8, fixed to the output shaft 321 of the driven wheel, to rotate, thereby rotating the pitch support 2 and ultimately adjusting the angle of the pitch support 2. Furthermore, in other embodiments, the gear reduction mechanism can also be a bevel gear transmission mechanism, where the number of teeth on the driving bevel gear is less than the number of teeth on the driven gear. Of course, it is easy to conceive that the gear reduction mechanism can also be a helical gear transmission mechanism, where the number of teeth on the driving helical gear is less than the number of teeth on the driven gear, as long as it allows the pitch support 2 to obtain a larger torque output. A pitch angle positioning mechanism is also provided between the pitch support 2 and the horizontal support 1. This pitch angle positioning mechanism includes a support rack 9 connected to one of the pitch support 2 and the horizontal support 1, and a support stop pin 10 connected to the other. The support rack 9 and the support stop pin 10 ensure that the pitch support 2 can be maintained at a certain angle relative to the horizontal support 1.

[0020] In this embodiment, the side of the horizontal support 1 is provided with the following... Figure 1 The L-shaped plate 33 shown has a gear reduction mechanism 3 mounted on a housing 34, and the housing 34 is mounted on the L-shaped plate 33. Figure 3 As shown, the bearing 5 of the input shaft 311 of the driving wheel 31 and the bearing 5 of the output shaft 321 of the driven wheel 32 are both mounted on the housing 34. A bearing end cover 6 is also provided to prevent foreign objects from entering the bearing 5 and causing damage to the bearing 5. A housing cover 35 is also provided on the upper part of the housing 34 to prevent foreign objects from entering the housing and affecting the operation of the gears.

[0021] In use, the pitch support 2 can be adjusted to a certain angle using the gear reduction mechanism 3 and the pitch angle positioning mechanism first, and then the busbar 4 can be placed on the busbar support device. Alternatively, the busbar 4 can be placed on the busbar support device first, and then the pitch support 2 can be adjusted to a certain angle using the gear reduction mechanism 3 and the pitch angle positioning mechanism.

[0022] In this embodiment, the support rack 9 is oscillatingly engaged with the pitch support 2 or horizontal support 1 to which it is located, and the swing axis of the support rack 9 is parallel to the pitch swing axis 8 of the pitch support 2. Figure 2In the illustrated embodiment, the support rack 9 is rotatably mounted on the side of the pitch support 2. Of course, in other embodiments, the support rack 9 can also be rotatably mounted on the horizontal support 1. In use, the support rack is first moved away from the support stop pin 10. After adjusting the pitch support 2 to the correct angle, the support rack is rotated back to engage with the support stop pin 10 to achieve positioning of the pitch support 2. The swinging support rack 9 is simple to operate and effectively ensures its positioning engagement with the support stop pin 10.

[0023] In this embodiment, the upper surface of each tooth on the support rack 9 is a sliding surface. When the pitch support 2 tilts upward, the support rack 9 automatically passes over the support stop pin 10 under the action of the sliding surface. If the upper surface of the support rack 9 were a straight surface, when the pitch support 2 tilts upward, the support rack 9 needs to be manually rotated to release the positioning engagement between the support rack 9 and the support stop pin 10, which is complicated. Therefore, in this embodiment, the upper surface of each tooth of the support rack 9 is set as a sliding surface so that when the pitch support 2 is adjusted upward, the positioning engagement between the support rack 9 and the support stop pin 10 can be released without manual operation. Of course, in another embodiment, the upper surface of each tooth of the support rack 9 can also be set as a straight surface. Of course, in other embodiments, in order to ensure that the positioning engagement between the support rack 9 and the support stop pin 10 is not easily released, grooves can also be provided on the upper surface of each tooth of the support rack 9 to ensure that the two are locked.

[0024] In this embodiment, when the pitch angle of the pitch support 2 is greater than 0 degrees, the connection point between the support rack 9 and the pitch support 2 is located on the side of the support stop pin 10 closer to the pitch pivot axis 8, and the support rack 9 can automatically swing towards the support stop pin 10 under the action of gravity. Figure 2 As shown, the support pin 10 is located below the connection point between the support rack 9 and the pitch support 2. Thus, without manual operation, the support rack 9 automatically swings towards the support pin 10 under gravity, making it simple and easy to operate. Furthermore, in other embodiments, the connection point between the support rack 9 and the pitch support 2 can also be located on the side of the support pin 10 away from the pitch axis 8 of the pitch support 2. In this case, the support rack 9 needs to have corresponding locking structures on the upper surface of each tooth to cooperate with the support pin 10.

[0025] In this embodiment, the support rack 9 is an arc-shaped rack. When the pitch support 2 pitches up or down, the path of a specific point on it is arc-shaped, and the arc-shaped rack can adapt to the path of the pitch support 2, and in situations such as... Figure 2 In the illustrated embodiment, the arc-shaped rack is positioned and engaged with the support stop pin 10 near the position where it is rotatably assembled with the horizontal support 1 and the pitch support 2, thus saving material on the arc-shaped rack 9. Furthermore, in other embodiments, the support rack 9 may also be a straight rack.

[0026] In this embodiment, the support rack 9 is an arc-shaped rack and is fixedly engaged with the pitch support 2 or horizontal support 1 to which it is located. The swing axis of the support rack 9 is parallel to the pitch swing axis 8. The support stop pin 10 is detachably connected to the pitch support 2 or horizontal support 1 to which it is located. In use, the support stop pin 10 is first removed to release its positioning engagement with the support rack 9. Then, the angle of the pitch support 2 is adjusted. After the angle is adjusted to the correct position, the support stop pin 10 is installed to achieve its positioning engagement with the support rack 9.

[0027] In this embodiment, a base support 21 for supporting and positioning the supported busbar is provided on the pitch support 2. The base support 21 is adjustablely installed on the pitch support 2 along its length. Figure 4 In the embodiment shown, the pitch support 2 is provided with a slide rail 22, and the bottom of both ends of the base 21 is provided with... Figure 6 The trapezoidal slider 23 shown can cooperate with the slide rail 22 to allow the base support 21 to move to different positions on the pitch support 2. Then, the base support 21 can be fixed to the pitch support 2 using fastening screws 24. Thus, the base support 21 can be flexibly adjusted in position as needed to meet the load-bearing requirements of different busbars 4. In this embodiment, the base support 21 is inverted trapezoidal. Therefore, when different busbars 4 are placed on the base support 21, different busbars 4 will contact different positions on the sides of the base support 21, thereby achieving support for busbars 4 of different specifications. Furthermore, in other embodiments, the base support 21 can also be V-shaped; of course, in other embodiments, the two sides of the base support 21 can also be curved. It is conceivable that in other embodiments, the base support 21 can also be semi-circular. A horizontal support base 11 is also provided on the horizontal support, and the shape of the horizontal support base 11 is consistent with the shape of the base support 21.

[0028] In this embodiment, a connecting sleeve is provided at the connection between the pitch support 2 and the horizontal support 1. The pitch pivot shaft 8 is rotatably mounted on the horizontal support 1 and its inner end is inserted into the connecting sleeve. Anti-rotation stop pins are cross-inserted on the pitch pivot shaft 8. A corresponding end of the connecting sleeve is provided with a fitting that cooperates with the anti-rotation stop pin. Figure 5 The anti-rotation slot is shown. Inserting a stop pin into the pitch pivot shaft 8 is a simple, efficient, and easy-to-manufacture method, and it efficiently transmits the rotation of the pitch pivot shaft 8 to the anti-rotation slot to drive the pitch support 2 to rotate. Furthermore, in other embodiments, the pitch pivot shaft 8 and the connecting sleeve can also transmit torque through a transmission key or a profile connection; of course, synchronous rotation of both can also be achieved through bonding or welding.

[0029] In this embodiment, the horizontal support 1 includes a pitch support pillow located near one end of the pitch support 2, and the pitch angle positioning mechanism is located at the pitch support pillow. A step is provided in the middle of the horizontal support 1 in this embodiment, so that the horizontal support has a higher horizontal extension end and a lower horizontal extension end. The lower horizontal extension end is the pitch support pillow. The bearing seat 7 is installed at the step of the horizontal support, and the pitch pivot shaft 8 of the pitch support 2 is rotatably mounted on the bearing seat 7. When the pitch angle of the pitch support 2 is 0 degrees, the bottom surface of the pitch support 2 is close to the top of the pitch support pillow, and at this time, the height of the pitch support 2 is the same as the higher horizontal extension end of the horizontal support 1. In other embodiments, the horizontal support 1 may not have a pillow; instead, a hinge lug may be provided on the horizontal support 1, which is rotatably mounted to the pitch pivot shaft 8 of the pitch support 2. Placing the pitch angle positioning mechanism at the pitch support pillow facilitates the positioning of the angle of the pitch support 2.

[0030] In this embodiment, the horizontal support 1 is equipped with casters 12. Without casters 12, the lifting device would be difficult to move, and the position of the busbar 4 would be difficult to adjust. Therefore, installing casters 12 on the horizontal support 1 makes the movement of the lifting device easier, and when supporting the busbar 4, it is easier to adjust the busbar 4 to a suitable position to meet the connection requirements of different electrical equipment.
