Description

Technical Field

[0001] The present application relates to the field of power equipment installation, and in particular to a right-angle bus duct pressing device and method. Background Art

[0002] In the power transmission system, bus duct is an important component connecting different electrical components. Its installation quality directly affects the operational safety and reliability of the entire system. The components of the bus duct mainly include the shell and several conductive bars stacked in the grooves of the shell. The bus ducts commonly used in the market are mostly linear designs, which are divided into horizontal bent bus ducts and vertical bent bus ducts. The bottom walls of the grooves of the two right-angled sides of the horizontal bent bus duct are in the same plane, while the two right-angled sides of the vertical bent bus duct are horizontal and vertical respectively, and the bottom walls of the grooves of the two are in two different and mutually perpendicular planes.

[0003] In the related art, the linear bus duct clamping device usually fixes and clamps the bus duct through a clamp. The design of this type of device is relatively simple. When faced with right-angle bus ducts, these traditional methods expose obvious limitations. First, the traditional clamping device cannot adapt to complex geometric shape changes, especially at the corners of the vertical bent bus duct. The clamping effect is poor and the clamping efficiency is not high, so there is still room for improvement. Summary of the Invention

[0004] In order to improve the compression effect and compression efficiency of the bus duct, the present application provides a right-angle bus duct compression device and method.

When the vertical bent bus duct is in place on the first workbench surface, the two sliding rod components are symmetrically distributed on both sides of the vertical bent bus duct, and the two ends of the oblique pressure assembly are respectively a hinged end and a free end, the hinged end of the oblique pressure assembly is hinged to the end of one of the sliding rod components, and the free end of the oblique pressure assembly is detachably connected to the end of the other sliding rod component; the downward pressure assembly is toward the corner position of the vertical bent bus duct, and the oblique pressure driving member is used to drive the sliding rod component to slide along its own length direction, so as to drive the oblique pressure assembly to press along the extension direction of the angular bisector of the vertical bent bus duct.

[0012] By adopting the above technical solution, the two sliding rod components are symmetrically distributed on both sides of the vertical bent bus duct, and then the inclined pressure component is swung to complete the connection action between the free end of the inclined pressure component and the end of the corresponding sliding rod component, so that the downward pressure component is directed toward the corner position of the vertical bent bus duct. By starting the inclined pressure driving member, the sliding rod component is driven to slide along its own length direction, and the inclined pressure component is driven to be pressed along the extension direction of the angle bisector of the vertical bent bus duct, which is beneficial to improve the pressing effect and pressing efficiency.

After the compression action is completed, the horizontal frame is swung to one side of the first workbench to facilitate the storage purpose of the vertical pressure cylinder.

[0015] Preferably, the horizontal pressure mechanism includes a limit frame and a horizontal pressure cylinder laterally arranged at the limit frame, the limit frame is used to contact the back side of the vertical edge of the vertical bent bus duct, and the horizontal pressure cylinder is used to laterally press the vertical edge of the vertical bent bus duct.

The second workbench is provided with two downward pressing mechanisms on the side, and the two downward pressing mechanisms are respectively used to press the horizontal edges and corner positions of the horizontal bent bus duct downward.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-3 This application is described in further detail.

[0036] Example 1 of the present application discloses a right-angle bus duct pressing device, referring to Figure 1 and Figure 2The embodiment of the present application provides a right-angle bus duct pressing device, which includes a first workbench 11, a vertical pressing mechanism 2, a horizontal pressing mechanism 4, and an oblique pressing mechanism 3. The first workbench 11 is used to place the vertical bent bus duct 6. A limit seat 13 is provided on the first workbench 11. The limit seat 13 is used to contact the back side of the vertical edge of the vertical bent bus duct 6; the vertical pressing mechanism 2 is used to vertically press the horizontal edge of the vertical bent bus duct 6 on the first workbench 11; the horizontal pressing mechanism 4 is used to horizontally press the vertical edge of the vertical bent bus duct 6 on the first workbench 11; the oblique pressing mechanism 3 is used to perform a 45° oblique pressing on the corner position of the vertical bent bus duct 6 on the first workbench 11, thereby achieving the purpose of improving the pressing effect and pressing efficiency of the bus duct.

[0037] Specifically, the first workbench 11 is made of a metal plate with high strength and corrosion resistance. The stopper 13 is fixed to the first workbench 11 by bolts. The height of the stopper 13 can be adjusted according to the size of the vertical bent busbar 6 to better fit the vertical side back of the vertical bent busbar 6.

[0038] The vertical pressure mechanism 2 comprises a vertical frame 21, a horizontal frame 22, and a vertical pressure cylinder 23. The vertical frame 21 is fixed to the first workbench 11, while the horizontal frame 22 is pivotally connected to the vertical frame 21, with its axis of rotation positioned vertically. The vertical pressure cylinder 23 is positioned vertically downward at the end of the horizontal frame 22, with a rubber pad mounted on the end of its piston rod to prevent damage to the bus duct. The piston rod of the vertical pressure cylinder 23 can extend downward to press down against the horizontal edge of the vertically curved bus duct 6.

[0039] The horizontal pressing mechanism 4 includes a limit frame 41 and a horizontal pressing cylinder 42. A longitudinal cylinder 14 is installed on the side of the first workbench 11. The longitudinal cylinder 14 is raised by a support frame, and the height of the support frame can be adjusted according to the size of the vertical bent bus duct 6. The limit frame 41 is U-shaped, and the limit frame 41 and the piston rod end of the longitudinal cylinder 14 are detachably connected. The horizontal pressing cylinder 42 is horizontally installed at one end of the limit frame 41. The end of the piston rod of the horizontal pressing cylinder 42 is also installed with a rubber pad to prevent damage to the bus duct. Through the extension of the longitudinal cylinder 14, the limit frame 41 is moved to the top of the limit seat 13, and the back side of the vertical bent bus duct 6 is abutted against the inner side of one end of the limit frame 41. The piston rod of the horizontal pressing cylinder 42 at the other end of the limit frame 41 is extended and presses the vertical edge of the vertical bent bus duct 6 horizontally. In other embodiments, the longitudinal cylinder 14 can be removed, and the staff can directly lift the limit frame 41 to the vertical edge of the vertical bent bus duct 6 to perform the pressing work.

[0040] The oblique pressure mechanism 3 includes two sliding rod members, an oblique pressure assembly 31 and an oblique pressure drive. The two sliding rod members are parallel to each other and have an angle of 45 degrees with the surface of the first workbench 11. When the vertical bent bus duct 6 is in place on the surface of the first workbench 11, the two sliding rod members are symmetrically distributed on both sides of the vertical bent bus duct 6. The two ends of the oblique pressure assembly 31 are respectively a hinged end and a free end. The hinged end is hinged to the end of one of the sliding rod members, and the free end is detachably connected to the end of the other sliding rod member. Specifically, the free end is fixed to the end of the corresponding sliding rod member by a pin. The oblique pressure assembly 31 is oriented toward the corner position of the vertical bent bus duct 6. The oblique pressure drive is used to drive the sliding rod member to slide along its own length direction to drive the oblique pressure assembly 31 to press along the extension direction of the angular bisector of the vertical bent bus duct 6. In this embodiment, the oblique pressure drive is specifically an oblique cylinder installed inside the first workbench 11, which is a commonly used telescopic drive member and will not be described again.

[0041] During the actual operation, first place the vertical bent bus duct 6 on the surface of the first workbench 11 so that the back side of the vertical edge contacts the side of the limit seat 13. Then start the vertical pressing mechanism 2, and by horizontally swinging the horizontal frame 22, move the vertical pressing cylinder 23 to the top of the horizontal edge of the vertical bent bus duct 6, start the vertical pressing cylinder 23, and the vertical pressing cylinder 23 extends downward to complete the pressing action on the horizontal edge of the vertical bent bus duct 6. Then start the horizontal pressing mechanism 4, and by extending the horizontal pressing cylinder 42, press the vertical edge of the vertical bent bus duct 6 laterally. Finally, start the oblique pressing mechanism 3, and drive the sliding rod component to slide along its own length direction through the oblique pressing drive component, driving the oblique pressing assembly 31 to press along the extension direction of the angular bisector of the vertical bent bus duct 6, thereby achieving comprehensive pressing of the vertical bent bus duct 6. In this embodiment, the diagonal pressure assembly 31 consists of a connecting rod 311 and a pressure block 312. The pressure block 312 is adapted to the corner position of the vertical curved bus duct 6 to enhance the squeezing effect of the pressure block 312 on the corner position of the vertical curved bus duct 6. The pressure block 312 is located in the middle of the connecting rod 311, and the two ends of the connecting rod 311 are respectively connected to two sliding rod members.

[0042] The right-angle busbar clamping device also includes a second workbench 12 for placing the horizontally bent busbar 7. Two downward-pressing mechanisms 5 are mounted on the second workbench 12. In this embodiment, the downward-pressing mechanisms 5 have the same structure and operating principle as the vertical-pressing mechanisms 2, and their description is omitted here. In this embodiment, the two downward-pressing mechanisms 5 are used to press down the horizontal edges and corners of the horizontally bent busbar, respectively. Furthermore, the first and second workbench 11, 12 are assembled side by side to form the main workbench 1.

[0043] Example 1 provides a right-angle bus duct pressing method, using a right-angle bus duct pressing device, including the following steps:

[0044] When pressing the vertical bent bus duct 6, first place the vertical bent bus duct 6 on the surface of the first workbench 11 so that the back side of the vertical edge contacts the side of the limit seat 13, then the vertical pressing mechanism 2, the horizontal pressing mechanism 4 and the oblique pressing mechanism 3 are put into place, and the horizontal edge, the vertical edge and the corner position of the vertical bent bus duct 6 are pressed respectively;

[0045] When the horizontal bent bus duct 7 is pressed, the horizontal bent bus duct 7 is placed in place on the second workbench 12, and the two pressing mechanisms 5 are respectively located above the corner position of the horizontal bent bus duct 7 and above one of the horizontal sides. The two pressing mechanisms 5 simultaneously press the horizontal bent bus duct 7 downward. After the pressing is completed, the two pressing mechanisms 5 are reset, and then the horizontal bent bus duct 7 is reversed so that the horizontal side of the horizontal bent bus duct 7 that is not pressed is moved to the bottom of one of the pressing mechanisms 5, and then the pressing mechanism 5 is started, and the pressing mechanism 5 presses the horizontal side that is not pressed.

[0046] The coordinated action of the vertical pressure mechanism 2, the horizontal pressure mechanism 4, and the diagonal pressure mechanism 3 comprehensively compresses the horizontal and vertical edges and corners of the vertically bent busbar 6, improving both the compression effect and efficiency. In particular, the design of the diagonal pressure mechanism 3, through its 45° angled compression at the corners, addresses the issue of poor corner compression often encountered with conventional compression devices, thereby enhancing the applicability and reliability of the overall compression mechanism.

[0047] Example 2

[0048] Reference Figure 2 The difference between Example 2 and Example 1 is that: the downward pressing mechanism 5 and the vertical pressing mechanism 2 of Example 2 are placed on both sides of the main workbench 1, and a horizontal driving component 8 is installed on the side of the main workbench 1 for driving the vertical pressing mechanism 2 to move horizontally back and forth between the first workbench 11 and the second workbench 12.

[0049] The transverse drive assembly 8 may be a conventional linear drive module, a transverse screw transmission mechanism, or a transverse drive cylinder and a guide rail.

[0050] In actual operation, when the vertical curved bus duct 6 is compressed, the operation steps are the same as those in Example 1. However, there are differences when the horizontal curved bus duct 7 is compressed.

[0051] In Example 2, when the horizontal bent bus duct 7 is compressed, the horizontal bent bus duct 7 is first placed in place on the second workbench 12, and the two pressing mechanisms 5 are respectively located above the corner position of the horizontal bent bus duct 7 and above one of the horizontal edges. The two pressing mechanisms 5 are started to press the horizontal bent bus duct 7 downward. After the compression is completed, the two pressing mechanisms 5 are reset, and then the horizontal bent bus duct 7 is reversed so that the uncompressed horizontal edge of the horizontal bent bus duct 7 moves to the bottom of one of the pressing mechanisms 5. The pressing mechanism 5 is started again to compress the uncompressed horizontal edge. If it is necessary to compress the two horizontal edges and the corner position of the horizontal bent bus duct 7 synchronously, the horizontal drive assembly 8 can be started to move the vertical pressing mechanism 2 to the top of the other horizontal edge of the horizontal bent bus duct 7, and then the vertical pressing mechanism 2 and the two pressing mechanisms 5 are started at the same time to compress the two horizontal edges and the corner position of the horizontal bent bus duct 7 synchronously.

[0052] The two downward pressing mechanisms 5 respectively press the horizontal edges and corners of the horizontal bent bus duct 7, ensuring uniformity and stability of the pressing. The horizontal drive assembly 8 is provided to achieve flexible switching of the vertical pressing mechanism 2 between the first workbench 11 and the second workbench 12, and the pressing operation of the vertical bent bus duct 6 and the horizontal bent bus duct 7 can be completed on the same device, improving the versatility and flexibility of the device.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
