Description

Technical Field

[0001] This utility model relates to the field of live-line working technology, and in particular to an insulating baffle and assembly equipment for an isolating switch for uninterrupted power operation. Background Technology

[0002] Currently, in 10kV distribution network live-line work, the disconnection of isolating switches may result in insufficient insulation at the break point due to equipment aging, humid environments, or other reasons, posing a risk of residual voltage or arcing. Traditional methods typically involve wrapping with insulating blankets or providing temporary shielding, but these methods have the following problems: the insulating blankets are not securely fixed and are easily displaced by wind or operational factors, posing a grounding safety hazard; the shielding range is limited and cannot completely cover the switch post insulators and fixed components; and the installation and dismantling efficiency is low, affecting the progress of the work.

[0003] In current technology, insulating baffles are mostly used for isolation and shielding. The insulating baffles are mostly made of high-strength epoxy resin insulating material. The fixed part and the moving part are connected and rotated by cylindrical pins. They can be opened and closed to adapt to different isolation switches and other support parts. However, in the structure of the insulating baffle, the moving part is located on both sides of the fixed part, and is connected and rotated by end riveting with T-shaped cylindrical pins. The traditional assembly method mostly adopts single-sided assembly, that is, first assemble the moving part on one side, and then continue to assemble the moving part on the other side. This assembly method is inefficient and not conducive to mass production and processing. Utility Model Content

[0004] The purpose of this utility model is to provide an insulating baffle for uninterrupted power supply isolation switches and its assembly equipment, aiming to solve the problem that existing assembly equipment is inefficient when assembling insulating baffles, which is not conducive to mass production and processing.

[0005] To achieve the above objectives, this utility model provides an assembly device, including a machine base and a riveting mechanism;

[0006] The riveting mechanism includes a mounting platform, a clamp, a movable plate, a punch plate, a hydraulic cylinder, and a guide device. The mounting platform is integrally mounted on the machine base. The clamp is detachably mounted on the top of the mounting platform for placing an insulating baffle. The movable plate is positioned above the clamp. The punch plate is fixedly connected to the movable plate and has two working punches arranged vertically and symmetrically. The hydraulic cylinder is fixed to the top of the machine base, and its output end is connected to the movable plate. The guide device is positioned on the side of the movable plate near the machine base.

[0007] The clamp is provided with a positioning groove that slides with the fixing part of the insulating baffle, and the bottom of the positioning groove is provided with symmetrical head limiting grooves of cylindrical pins.

[0008] The clamp also has first limiting parts symmetrically arranged on both sides of its upper surface.

[0009] The fixture also has symmetrically arranged second limiting parts on its upper surface.

[0010] The guiding device includes a T-shaped sliding sleeve and a guide rod. The T-shaped sliding sleeve is fixed to the top of the machine base. The guide rod is threadedly connected to the moving plate and slidably connected to the T-shaped sliding sleeve.

[0011] The guide device further includes a protective tube, which is detachably connected to the machine base and located outside the T-shaped sliding sleeve.

[0012] The assembly equipment further includes a stabilizing mechanism, which includes a guide rail slider device and a connecting frame. The guide rail slider device is located on the rear side of the machine base and is arranged symmetrically. One side of the connecting frame is connected to the linear slider of the guide rail slider device, and the other side is connected to the moving plate.

[0013] One of them is an insulating baffle for a non-power-on operation isolating switch. The insulating baffle is made of epoxy resin and glass fiber composite laminate with a thickness of 8-12mm. Its fixed part and movable part are rotatably connected and can be assembled by the assembly equipment.

[0014] This utility model discloses an assembly device. During assembly, the head of a T-shaped cylindrical pin is first placed into the head limiting groove at the bottom of the positioning groove of the fixture. Then, the fixed part of the insulating baffle is slidably installed, and the movable parts on both sides of the fixed part are further slidably installed. The first limiting part can be used to limit the movable part of the insulating baffle during assembly. Then, the hydraulic cylinder is controlled to extend. After the hydraulic cylinder is activated, it pushes the moving plate downward, thereby driving the punch plate downward. After the punch plate descends, the two working punches at its bottom can directly punch and deform the end of the cylindrical pin simultaneously, so that the T-shaped cylindrical pin is converted into an I-shaped structure to complete the rapid assembly. This solves the problem of low efficiency and unfavorable mass production processing of existing assembly equipment when assembling insulating baffles. Attached Figure Description

Detailed Implementation

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention. Example 1

[0024] like Figures 1 to 3 As shown, where Figure 1 This is a schematic diagram of the overall structure of the assembly equipment. Figure 2 This is a structural schematic diagram of fixture 103. Figure 3 This is a schematic diagram showing the location of the positioning groove 108. This utility model provides an assembly device including a machine base 101 and a riveting mechanism. The riveting mechanism includes a mounting platform 102, a clamp 103, a moving plate 104, a punch plate 105, a hydraulic cylinder 106, and a guiding device. The guiding device includes a T-shaped sliding sleeve 113, a guide rod 114, and a protective tube 115. The aforementioned solution solves the problem of low efficiency in assembling insulating baffles using existing assembly equipment, which is detrimental to mass production. It is understood that the aforementioned solution can improve assembly efficiency.

[0025] In this embodiment, the machine base 101 can be fixed by bolts.

[0026] The mounting platform 102 is integrally mounted on the machine base 101. The clamp 103 is detachably mounted on the top of the mounting platform 102 for placing the insulating baffle 107. The movable plate 104 is positioned above the clamp 103. The punch plate 105 is fixedly connected to the movable plate 104 and has two working punches arranged vertically and symmetrically. The hydraulic cylinder 106 is fixed to the top of the machine base 101, and its output end is connected to the movable plate 104. The guide device is positioned on the movable plate 104 near the machine base 101. On one side; the clamp 103 is fixed to the top of the mounting platform 102 by positioning pins and bolts for placing workpieces; the punch plate 105 is fixed to the bottom of the moving plate 104 by positioning pins and bolts arranged from bottom to top; working punches are symmetrically arranged at the bottom of the punch plate 105; the hydraulic cylinder 106 is fixed to the top of the machine base 101 by bolts; the external thread end on the piston rod at its output end is directly connected to the connecting threaded hole on the moving plate 104; the guiding device is used to guide the moving plate 104 when it moves vertically.

[0027] The clamp 103 is provided with a positioning groove 108 that slides with the fixed part of the insulating baffle 107. The bottom of the positioning groove 108 is symmetrically provided with head limiting grooves 110 for cylindrical pins 109. The positioning groove 108 is set according to the outer contour structure of the movable part of the insulating baffle 107. The bottom of the positioning groove 108 is provided with a T-shaped structure for the head limiting grooves 110 for the cylindrical pins 109. The size of the positioning groove 108 can be slightly larger than the head of the cylindrical pins 109.

[0028] The clamp 103 is also symmetrically provided with first limiting parts 111 on both sides of its upper surface. The first limiting parts 111 are set according to the outer contour of the movable part of the insulating baffle 107, which facilitates the sliding insertion and limiting of the movable part during assembly.

[0029] Secondly, the upper surface of the clamp 103 is also provided with symmetrically arranged second limiting parts 112. The second limiting parts 112 are also set according to the outer contour of the movable part of the insulating baffle 107, which further facilitates the sliding insertion of the movable part and the limiting cooperation during assembly.

[0030] Then, the T-shaped sliding sleeve 113 is fixed to the top of the machine base 101; the guide rod 114 is threadedly connected to the moving plate 104 and slidably connected to the T-shaped sliding sleeve 113. The T-shaped sliding sleeve 113 is fixed by bolts, and the bottom external thread end of the guide rod 114 directly engages with the threaded connection hole on the moving plate 104 to achieve connection, and slidably connects to the T-shaped sliding sleeve 113.

[0031] Finally, the protective tube 115 is detachably connected to the machine base 101 and is located outside the T-shaped sliding sleeve 113. The bottom of the protective tube 115 has multiple threaded holes arranged in a ring for easy fixing with bolts arranged from bottom to top. The function of the protective tube 115 is to reduce the bending deformation caused by the guide rod 114 being impacted laterally at its top end after the hydraulic cylinder 106 is reset, thus improving safety.

[0032] When using this invention to solve the problem of low efficiency and unfavorable conditions for mass production of insulating baffles in existing assembly equipment, the assembly process involves first placing the head of the T-shaped cylindrical pin 109 into the head limiting groove 110 at the bottom of the positioning groove 108 of the fixture 103, then slidingly installing the fixing part of the insulating baffle 107, and further slidingly installing the movable parts on both sides of the fixing part. During installation, the through holes on the fixing part and the movable parts need to slide and engage with the cylindrical pin 109. The first limiting part 111 and the second limiting part 112 can be used to limit the movable part of the insulating baffle 107 during assembly. Then, the hydraulic cylinder 106 is controlled to extend. After the hydraulic cylinder 106 moves, it pushes the moving plate 104 downward, thereby driving the punch plate 105 downward. After the punch plate 105 moves downward, the two working punches at its bottom can directly punch and deform the end of the cylindrical pin 109 away from the head at the same time, so that the T-shaped cylindrical pin 109 is converted into an I-shaped structure to complete the rapid assembly. In this application, the movable parts on both sides of the fixed part of the insulating baffle 107 can be assembled at the same time during assembly, thereby solving the problem of low efficiency and unfavorable mass production of insulating baffles in existing assembly equipment. Example 2

[0033] like Figure 4 and Figure 5 As shown, where Figure 4 This is a schematic diagram of the overall structure of the assembly equipment. Figure 5 This is a structural schematic diagram of the connecting frame 202. Based on the first embodiment, this utility model provides an assembly device, which further includes a stabilizing mechanism. The stabilizing mechanism includes a guide rail slider device 201 and a connecting frame 202.

[0034] The guide rail slider device 201 is located on the rear side of the machine base 101 and is arranged symmetrically. One side of the connecting frame 202 is connected to the linear slider of the guide rail slider device 201, and the other side is connected to the moving plate 104. The guide rail slider device 201 consists of a linear guide rail and a linear slider. The linear guide rail is fixed by countersunk bolts, and the linear slider can slide vertically on the linear guide rail. A rectangular cavity is provided on the machine base 101 for the connecting frame 202 to pass through. One side of the connecting frame 202 is connected to the linear slider of the guide rail slider device 201 by bolts, and the other side is connected to the moving plate 104 by bolts.

[0035] In this embodiment, by setting the guide rail slider device 201 and the connecting frame 202, a guiding structure can be further formed, thereby improving the stability of the vertical movement of the moving plate 104.

[0036] Finally, as Figure 6 As shown, Figure 6 This is a schematic diagram of the overall structure of an insulating baffle 300 for uninterrupted power supply (UPS) operations. The insulating baffle 300 is made of epoxy resin and fiberglass composite laminate with a thickness of 8-12mm. Its fixed part 301 and movable part 302 are rotatably connected and can be assembled using the assembly equipment described above. A bakelite handle 303 is installed on the movable part 302 of the UPS.
