Description

Technical Field

[0001] This invention relates to a single-pole assembly fixture for disconnecting switches. Background Technology

[0002] like Figure 1 As shown, the disconnecting switch single pole includes a cylindrical body 102, inside which an isolating stationary contact 101, an intermediate electrical connection 103, and a grounding stationary terminal 104 are installed. The intermediate electrical connection 103 is fixedly mounted on a basin-type insulator 105 and is installed inside the cylindrical body 102 through the basin-type insulator 105.

[0003] In the prior art, when installing the intermediate electrical connection 103, the convex end of the basin-type insulator 105 is first placed upwards, then the assembled intermediate electrical connection 103 is placed on the convex end of the basin-type insulator 105 and securely connected with bolts. The basin-type insulator 105 and the intermediate electrical connection 103 together constitute the assembly. Figure 2 As shown, the assembly is manually lifted and rotated clockwise by a set angle. Figure 1 The centerline of the intermediate electrical connection 103 is set at an angle of approximately 62° with the vertical axis of the cylinder 102, causing the assembly to slowly move into the cylinder 102 from the left side of the cylinder hole. After it is in place, the assembly is rotated clockwise until the centerline of the intermediate electrical connection 103 is parallel to the vertical axis of the cylinder 102. Figure 3 As shown; then move the assembly upwards so that the centerline of the basin insulator 105 is aligned with the left cylinder hole (i.e., the assembly inlet), as shown. Figure 4 As shown; finally, move the assembly to the right so that the basin insulator 105 aligns with the flange of the left cylinder hole, and use bolts to fix the basin insulator 105 to the left cylinder hole of the cylinder 102, thus completing the installation of the intermediate electrical connection 105.

[0004] When assembling the aforementioned intermediate electrical connection into the cylinder, workers need to hold the assembly by hand. The assembly is quite heavy, which increases the labor intensity for workers and is prone to safety accidents. Moreover, during installation, workers cannot properly adjust the entry angle of the assembly, which will cause shaking when holding the assembly. The basin-type insulator is relatively brittle, which can easily damage the assembly and thus affect the quality of the disconnecting switch. Summary of the Invention

[0005] The purpose of this invention is to provide a single-pole assembly fixture for disconnecting switches, in order to solve the technical problem in the prior art where workers cannot properly adjust the entry angle of the assembly during installation, causing wobbling when holding the assembly and making it prone to collisions.

[0006] To achieve the above objectives, the technical solution of the single-pole assembly fixture for the disconnecting switch of the present invention is as follows:

[0007] A single-pole assembly fixture for a disconnecting switch includes a horizontal worktable with a cylindrical support and an assembly support on the worktable. The cylindrical support supports the cylindrical body of the disconnecting switch single pole, such that the assembly inlet on the cylindrical body faces the assembly support. The cylindrical support has a support axis, which is parallel to the axis of the cylindrical body supported on the cylindrical support. The assembly support supports the assembly. One of the assembly support and the cylindrical support is guided relative to the other in a horizontal plane along a predetermined guide direction. The predetermined guide direction forms a predetermined angle with the support axis, and the predetermined angle is such that the intermediate electrical connection on the assembly is inserted into the cylindrical body. The initial installation angle at the inlet of the assembly; one of the cylinder support and the assembly support includes a rotating seat for fixing the corresponding cylinder or assembly; the rotating seat has an initial position and an alignment position in its rotational stroke; the initial position is used to make the axis of the intermediate electrical connection of the assembly on the rotating seat parallel to the set guide direction; the alignment position is used to make the axis of the intermediate electrical connection of the assembly on the rotating seat parallel to the axial direction of the support; one of the cylinder support and the assembly support without a rotating seat can move relative to the rotating seat along the axial direction of the support, and can move relative to the rotating seat in a horizontal direction perpendicular to the axial direction of the support.

[0008] The beneficial effects are: by moving one of the cylinder support and the component support without a rotating seat relative to the rotating seat, the component can enter the cylinder according to a certain assembly route by means of the tooling. This not only saves manpower and reduces labor intensity, but also avoids collision between the cylinder and the component, and improves the assembly efficiency of the disconnector switch single pole.

[0009] Furthermore, the assembly support includes the rotating seat and the inclined slide, the rotating seat is located above the inclined slide and is rotatably mounted on the inclined slide, and the assembly support can slide along a set guide direction via the inclined slide.

[0010] The beneficial effect is that, due to the weight of the cylinder, the mounting bracket slides along the set guide direction via the inclined slide, making adjustment easier.

[0011] Furthermore, one of the rotating seat and the inclined slide is provided with a rotating seat limiting structure, and the other is provided with an initial position limiting hole and an alignment limiting hole; the rotating seat limiting structure includes a limiting pin, which respectively engages with the initial position limiting hole and the alignment limiting hole to limit the rotating seat in the initial position and the alignment position.

[0012] The beneficial effect is that by setting a limiting structure for the rotating seat, the stability of the rotating seat after it has rotated into place is ensured.

[0013] Furthermore, the rotating seat limiting structure is an elastic limiting structure, which includes the limiting pin and the elastic element; the elastic element is used to apply an elastic force to the limiting pin so that the limiting pin is limited and engaged with the corresponding limiting hole.

[0014] The beneficial effects are: the elastic limit structure is relatively simple to position, and it is convenient for the rotating seat to switch between the initial position and the aligned position.

[0015] Furthermore, the assembly support also includes a longitudinal slide, through which the assembly support can slide along the support axis.

[0016] The beneficial effect is that, due to the weight of the cylinder, the mounting bracket moves along the axial direction of the bracket via the longitudinal slide, making adjustment easier.

[0017] Furthermore, the longitudinal slide has a starting position and an ending position in its sliding stroke, and the inclined slide is provided with an inclined slide positioning structure. The longitudinal slide is provided with an initial position positioning hole and an ending position positioning hole. The inclined slide positioning structure includes a positioning pin, which is positioned and engaged with the initial position positioning hole and the ending position positioning hole respectively, so that the rotating seat is in the starting position and the ending position.

[0018] The beneficial effect is that by setting up an inclined slide positioning structure, the stability of the inclined slide after it slides into place is guaranteed.

[0019] Furthermore, the inclined slide positioning structure is an elastic positioning structure, which includes the positioning pin and the elastic element; the elastic element is used to apply an elastic force to the positioning pin so that the positioning pin is limited to the corresponding positioning hole.

[0020] The beneficial effects are: the elastic positioning structure is relatively simple to position, and it is convenient for the inclined slide to switch between the starting position and the ending position.

[0021] Furthermore, the cylindrical support has a relief recess to avoid the longitudinal slide.

[0022] The beneficial effect is that by setting a clearance recess on the cylinder support, it is easier to arrange the cylinder support and the longitudinal slide.

[0023] Furthermore, the rotating base is provided with a positioning component, which is used to position and fix the assembly; the positioning component is mounted on the rotating base in an adjustable position in the vertical direction.

[0024] The beneficial effect is that when the center line of the basin insulator of the assembly does not coincide with the center line of the assembly inlet, the positioning component can be finely adjusted in the vertical direction to ensure the fitting accuracy of the basin insulator and the assembly inlet.

[0025] Furthermore, a vertically extending lead screw is rotatably mounted on the rotating seat, and when the lead screw rotates, the positioning component is driven by the lead screw to be mounted on the rotating seat in an adjustable vertical position.

[0026] The advantages are that the lead screw adjustment method is relatively simple and the cost is low. Attached Figure Description

[0041] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0042] Embodiment 1 of the single-pole assembly fixture for the disconnector switch of the present invention:

[0043] like Figure 5 and Figure 7 As shown, the single-pole assembly fixture for the disconnecting switch includes a horizontal worktable 1. The left and right sides of the horizontal worktable 1 are respectively provided with a longitudinal sliding plate 15 and a transverse sliding plate 4. A support plate 5 is provided on the transverse sliding plate 4 to support the cylinder 6. The upper part of the support plate 5 has a concave structure adapted to the cylinder 6. An assembly inlet 7 is provided on the left side of the cylinder 6. An inclined sliding plate 8 is slidably mounted on the longitudinal sliding plate 15, and a rotating plate 10 is rotatably mounted on the inclined sliding plate 8 along its vertical axis. Figure 8 As shown, a vertical plate 13 is fixedly mounted on the rotating plate 10, and a positioning plate 12 is slidably mounted on the vertical plate 13. The positioning plate 12 constitutes a positioning component for positioning and installing the assembly 26. The transverse sliding plate 4 and the support plate 5 together constitute a cylinder support. The cylinder support has a support axis, which is along the front-to-back direction and is parallel to the axis of the cylinder 6 supported on the cylinder support. The inclined sliding plate 8 constitutes an inclined slide, and the sliding direction of the inclined sliding plate 8 is a set guide direction. It should be noted that the support plate 5 is made of polytetrafluoroethylene (PTFE), which is relatively soft to ensure that the cylinder 6 will not be damaged.

[0044] It should be noted that assembly 26 consists of a basin-type insulator and an intermediate electrical connection.

[0045] In this embodiment, the transverse sliding plate 4 is slidably mounted on the horizontal worktable 1 in the left-right direction. Specifically, as shown... Figure 5 As shown, a transverse guide rail 2 is fixed on the upper surface of the right side of the horizontal worktable 1, extending in the left-right direction. A transverse slider 3 is fixed on the lower surface of the transverse slide plate 4, and the transverse slider 3 is slidably mounted on the transverse guide rail 2 to allow the transverse slide plate 4 to slide on the horizontal worktable 1 in the left-right direction. The transverse guide rail 2 is fixed to the horizontal worktable 1 with screws, and the transverse slider 3 is fixed to the transverse slide plate 4 with screws.

[0046] like Figure 7 As shown, there are two transverse guide rails 2 spaced apart along the front-to-back direction. Two transverse sliders 3 are provided on the transverse slide plate 4 corresponding to each transverse guide rail 2 to ensure the stability of the transverse slide plate 4 during left-to-right sliding. The distance between the two transverse guide rails 2 is approximately 700mm.

[0047] In this embodiment, the left side of the horizontal sliding plate 4 is provided with an avoidance recess 21, which is adapted to the right side of the vertical sliding plate 15 so as to avoid the right side of the vertical sliding plate 15 during the left and right sliding of the horizontal sliding plate 4.

[0048] In this embodiment, the longitudinal slide plate 15 is slidably mounted on the horizontal worktable 1 in the front-to-back direction, and the longitudinal slide plate constitutes a longitudinal slide block. Specifically, as shown... Figure 7 As shown, a longitudinal guide rail 20 is provided on the upper surface of the horizontal worktable 1, extending in the front-to-back direction. A longitudinal slider 17 is provided on the lower surface of the longitudinal slide plate 15, and the longitudinal slider 17 is slidably mounted on the longitudinal guide rail 20 to enable the longitudinal slide plate 15 to be slidably mounted on the horizontal worktable 1 in the front-to-back direction. The longitudinal guide rail 20 is fixed to the horizontal worktable 1 by screws, and the longitudinal slider 17 is fixed to the longitudinal slide plate 15 by screws.

[0049] It should be noted that the longitudinal guide rail 20 is arranged perpendicular to the transverse guide rail 2.

[0050] There are two longitudinal guide rails 20 arranged at intervals along the left and right directions, and two longitudinal sliders 17 are provided on the longitudinal slide plate 15 corresponding to each longitudinal guide rail 20 to ensure the stability of the longitudinal slide plate 15 during the forward and backward sliding process.

[0051] like Figure 5 and Figure 7 As shown, the upper surface of the longitudinal slide plate 15 is also provided with an inclined guide rail 19. The angle between the inclined guide rail 19 and the longitudinal guide rail 20 is approximately 62°. An inclined slider 18 is provided on the lower side of the inclined slide plate 8. The inclined slider 18 is slidably mounted on the inclined guide rail 19 to achieve the slidable mounting of the inclined slide plate 8 on the longitudinal slide plate 15. There are two inclined guide rails 19 arranged side by side, and two inclined sliders 18 are provided on the inclined slide plate 8 corresponding to each inclined guide rail 19.

[0052] like Figure 6 and Figure 7 As shown, the inclined slide plate 8 has a starting position and an ending position during its sliding stroke. An initial position positioning hole 28 is provided on the upper surface of the inclined slide plate 8 corresponding to the initial position, and an ending position positioning hole 30 is provided corresponding to the ending position. The ending position positioning hole 30 constitutes a horizontal worktable positioning hole. An elastic positioning structure 16 is provided on the lower side of the inclined slide plate 8, constituting an inclined slide positioning structure. The elastic positioning structure 16 includes a sleeve 161 threaded onto the inclined slide plate 8. A compression spring 162 and a positioning pin 163 are provided inside the sleeve 161. The compression spring 162 is an elastic element. Under the elastic force of the compression spring 162, the positioning pin 163 is used to position and engage with the initial position positioning hole 28 and the ending position positioning hole 30 to position the inclined slide plate 8 at the starting and ending positions. The positioning pin 163 and the sleeve 161 are engaged by a stepped stop to prevent the positioning pin 163 from dislodging from the sleeve 161 under the elastic force of the compression spring 162.

[0053] like Figure 5 and Figure 6As shown, a rotating shaft is fixed to the lower side of the rotating plate 10 by bolts. The rotating plate 10 is rotatably mounted on the inclined sliding plate 8 through the rotating shaft and bearing 9. The rotating plate 10 has an entry position and an adjustment position during its rotation stroke. When the rotating plate 10 is in the entry position, the inclined sliding plate 8 slides from the initial position to the end position. When the rotating plate 10 is in the adjustment position, the assembly 26 is adjusted from an inclined state to align the basin-type insulator of the assembly 26 with the assembly inlet.

[0054] like Figure 6 and Figure 7 As shown, the lower side of the rotating plate 10 is provided with an initial position limiting hole 27 and an alignment limiting hole 29, and the upper side of the inclined slide plate 8 is provided with a rotating seat limiting structure 14. Specifically, the rotating seat limiting structure 14 includes a limiting pin 141 and a stud 142. The stud 142 is threadedly connected to the inclined slide plate 8, and adhesive is applied to the external thread of the stud 142 to fix the stud 142 to the inclined slide plate 8. The limiting pin 141 is threadedly connected to the upper end of the stud 142. The upper end of the limiting pin 141 is provided with a cone, which forms a positioning protrusion. When the limiting pin 141 moves spirally upward, the cone engages with the initial position limiting hole 27 and the alignment limiting hole 29 to limit the rotating plate to the initial and alignment positions. When the limiting pin 141 moves spirally downward, the cone disengages from the initial position limiting hole 27 and the alignment limiting hole 29 to release the positioning of the rotating plate. The rotation axis of the initial position limiting hole 27 and the rotation axis of the rotating plate 10 form a first plane, and the rotation axis of the alignment limiting hole 29 and the rotation axis of the rotating plate 10 form a second plane. The angle between the first plane and the second plane is approximately 62°. It should be noted that when the rotating plate is in the initial position, the axis of the intermediate electrical connection of the mounting parts on the positioning plate is parallel to the sliding direction of the inclined slide plate; when the rotating plate is in the alignment position, the axis of the intermediate electrical connection of the mounting parts on the positioning plate is parallel to the front-back direction.

[0055] like Figure 5 and Figure 8 As shown, the upright plate 13 is fixed to the rotating plate 10 with screws, and the positioning plate 12 is adjustable in the vertical direction. The rotating plate, the upright plate, and the positioning plate together constitute a rotating seat. Specifically, a vertical guide rail 23 is fixedly mounted on the upright plate 13, extending vertically. The positioning plate 12 has a vertical slider 22 and a nut 25 on the side facing the vertical guide rail 23. The vertical slider 22 is guided and assembled onto the vertical guide rail 23 in the vertical direction. There are two vertical guide rails 23 arranged side by side, and a fixing block is provided between the two vertical guide rails 23. The upper end of the fixing block has a blind hole with an upward opening, and the wall of the blind hole has a blind hole annular groove. In other embodiments, if the center line of the basin insulator of the assembly is at the same height as the center line of the assembly inlet before assembly, the positioning plate does not need to be adjustable in the vertical direction.

[0056] The upper part of the upright plate 13 is provided with a lead screw seat 31, on which a lead screw 24 is rotatably mounted via a bearing. The outer circumferential surface of the lower end of the lead screw 24 is provided with a lead screw ring groove, and a retaining spring is provided in the lead screw ring groove. After the lower end of the lead screw 24 is inserted into the blind hole, the retaining spring expands and enters the blind hole ring groove, so that the lower end of the lead screw 24 is rotatably assembled in the blind hole of the fixing block. The upper end of the lead screw 24 is provided with a handwheel 11, which facilitates driving the lead screw 24 to rotate. The nut 25 is threadedly connected to the middle position of the lead screw 24. When the handwheel 11 drives the lead screw to rotate, the nut 25 moves upward relative to the lead screw 24, and at the same time drives the positioning plate 12 to move upward.

[0057] In this embodiment, the rotating seat, the longitudinal slide, and the inclined slide together constitute the assembly support.

[0058] During the single-pole assembly of the disconnecting switch, the positioning pin 163 of the elastic positioning structure 16 is in the initial positioning hole 28, and the tapered part of the limiting pin 141 is in the alignment limiting hole 29. The cylinder 6 is placed on the support plate 5, and the assembly 26 is fixed on the positioning plate 12. Then, the inclined sliding plate 8 is pushed towards the cylinder 6 to disengage the positioning pin 163 from the initial positioning hole 28 until the positioning pin 163 moves to the final positioning hole 30 and is pushed out by the compression spring 162. At this time, the inclined sliding plate 8 moves into place and is positioned by the positioning pin 163, and cannot move. The positional relationship between the assembly 26 and the cylinder 6 is as follows. Figure 2 As shown. Then rotate the limiting pin 141 downwards to release the limiting effect on the rotating plate 10. Rotate the rotating plate 10 clockwise until the alignment limiting hole 29 is above the limiting pin 141. At this point, the rotating plate 10 has rotated into position. Figure 3 As shown, the centerline of the basin-type insulator of assembly 26 is parallel to the centerline of the assembly inlet 7. Then, the limiting pin 141 is rotated upwards, causing the rotating plate 10 to be limited by the cone portion of the limiting pin 141 and unable to move. Then, the longitudinal sliding plate 15 is moved backwards, as shown... Figure 4 As shown, align the centerline of the basin insulator of assembly 26 with the centerline of assembly inlet 7. Then move the transverse slide plate 4 to the left, so that the basin insulator of assembly 26 abuts against the flange of assembly inlet 7 and is secured with bolts. Finally, remove assembly 26 from positioning plate 12 to complete the single-pole assembly of the disconnecting switch. Figure 1 As shown. If there is a deviation in the vertical direction during the process of aligning the center line of the basin insulator of the assembly 26 with the center line of the assembly inlet 7, the height of the assembly 26 can be finely adjusted by the handwheel 11 to ensure that the center line of the basin insulator of the assembly 26 coincides with the center line of the assembly inlet 7.

[0059] It should be noted that, in order to ensure that the longitudinal slide plate 15 and the transverse slide plate 4 do not move during assembly, set screws can be provided on the corresponding longitudinal slide plate 17 and transverse slide plate 3. When no movement is required, the longitudinal slide plate 15 and the transverse slide plate 4 can be locked onto the corresponding guide rails; when movement is required, the locking of the longitudinal slide plate 15 and the transverse slide plate 4 can be released.

[0060] Embodiment 2 of the single-pole assembly fixture for the disconnector switch of the present invention:

[0061] The difference from Embodiment 1 is that a longitudinal sliding plate is not provided; instead, the inclined guide rail is directly fixed to the horizontal worktable. The transverse sliding plate slides on the horizontal worktable in the left-right direction via the transverse slider, and can also slide forward relative to the transverse slider. After the inclined sliding plate slides to its end position and the rotating plate is rotated clockwise into place, the transverse sliding plate is first moved forward, and then moved to the left, so that the center line of the basin insulator of the assembly coincides with the center line of the assembly inlet.

[0062] Embodiment 3 of the single-pole assembly fixture for the disconnector switch of the present invention:

[0063] The difference from Embodiment 1 is that the height of the transverse slide from the horizontal worktable is less than the height of the longitudinal slide from the horizontal worktable. When the transverse slide moves in the left and right directions, its left side is below the longitudinal slide. In this case, it is not necessary to set an avoidance recess on the transverse slide.

[0064] Embodiment 4 of the single-pole assembly fixture for the disconnector switch of the present invention:

[0065] like Figure 6 As shown, the difference from Embodiment 1 is that the transverse slide plate cannot slide left or right. While the longitudinal slide plate slides along the front-to-back direction on the horizontal worktable via the longitudinal slider, it can also slide left or right relative to the longitudinal slider. After the diagonal slide plate reaches its endpoint and the rotating plate is rotated clockwise into position, the longitudinal slide plate is first moved backward, and then further backward, so that the center line of the basin-type insulator of the assembly coincides with the center line of the assembly inlet.

[0066] Embodiment 5 of the single-pole assembly fixture for the disconnector switch of the present invention:

[0067] like Figure 9 As shown, the difference from Embodiment 1 is that the upper side of the inclined slide plate 8 is provided with an initial position limiting hole 27 and an alignment limiting hole 29, and the lower side of the rotating plate 10 is provided with a rotating seat limiting structure 14. In other embodiments, the rotating seat limiting structure can be replaced by an elastic positioning structure 16.

[0068] Embodiment 6 of the single-pole assembly fixture for the disconnector switch of the present invention:

[0069] The difference from Embodiment 1 is that the thickness of the inclined slide plate is larger, and the lower side of the inclined slide plate is provided with a blind hole extending in the vertical direction. The elastic pressing structure includes a positioning pin and an elastic element. Both the elastic element and the positioning pin are assembled in the blind hole. One end of the elastic element presses against the bottom of the blind hole, and the other end presses against one end of the positioning pin. The length of the positioning pin is greater than the interval between the lower side of the inclined slide plate and the upper side of the worktable.

[0070] Embodiment 7 of the single-pole assembly fixture for the disconnector switch of the present invention:

[0071] The difference from Embodiment 1 is that the rotating seat limiting structure on the inclined sliding plate can be replaced by an elastic positioning structure.

The scope of patent protection of the present invention shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention shall also be included within the scope of protection of the present invention.
