Description

Technical Field

[0001] This application relates to the field of column-mounted circuit breakers, and more particularly to an isolation spindle assembly fixture. Background Technology

[0002] A pole-mounted circuit breaker is a high-voltage switching device installed on the poles (towers) of power distribution lines to switch on and off load current, overload current and short-circuit current. It is a key protection and control device for power distribution networks.

[0003] Disconnecting switches are an important component of pole-mounted circuit breakers, such as Figure 1 As shown, the disconnecting switch includes an isolation spindle 5, an isolation crank arm 6, an isolation connecting plate, and an isolation insulating rod 7. The isolation insulating rod 7 is connected to the contact system. When the isolation spindle 5 rotates, the opening and closing of the contacts are realized through the cooperation of the isolation crank arm 6, the isolation connecting plate, and the isolation insulating rod 7.

[0004] Currently, the assembly method for the isolation spindle 5 and the isolation crank arm 6 typically involves placing multiple isolation crank arms 6 on a platform. Each isolation crank arm 6 has a connecting block 61 with mounting holes 62 on its inner side. The isolation spindle 5 needs to pass through these mounting holes 62 for assembly. However, the position of the isolation crank arms 6 is prone to change during installation, making it impossible for the isolation spindle 5 to smoothly pass through multiple isolation crank arms 6 at once. This necessitates adjustments to the position of the isolation crank arms 6, resulting in low assembly efficiency. Utility Model Content

[0005] To improve the assembly efficiency of the isolation spindle, this application provides an isolation spindle assembly fixture.

[0006] This application provides an isolation spindle assembly fixture, which adopts the following technical solution:

[0007] An isolation spindle assembly fixture includes a base, a fixing device, a placement frame, and a pushing device; the pushing device and the placement frame are both disposed on the base.

[0008] The fixing device includes a clamping assembly and a support assembly; the support assembly is disposed on the base and is used to support the isolation crank arm.

[0009] The clamping assembly includes a first clamping seat, a second clamping seat, and a locking member; the first clamping seat is connected to the base, and the isolation crank arm is placed on the first clamping seat;

[0010] The locking member locks the first clamping seat and the second clamping seat, so that the first clamping seat and the second clamping seat clamp the end of the isolation crank arm connected to the isolation spindle;

[0011] The mounting rack is used to hold the isolation spindle;

[0012] The pushing device pushes the isolation spindle away from the placement frame and through the isolation crank arm.

[0013] By adopting the above technical solution, the support assembly ensures that the isolation crank arm is stably placed on the first clamping seat, improving the stability of the isolation crank arm installation. After the isolation crank arm is placed between the first and second clamping seats, the locking member locks the first and second clamping seats, thereby fixing the end of the isolation crank arm connected to the isolation spindle. This reduces the possibility of the isolation crank arm moving during the process of the pushing device pushing the isolation spindle through multiple isolation crank arms, improving assembly efficiency.

[0014] Optionally, the locking component includes a latch and a locking seat, the locking seat being connected to the first clamping seat and the latch being connected to the second clamping seat; the latch cooperates with the locking seat to lock the first connecting seat and the second connecting seat.

[0015] By adopting the above technical solution, after the isolation crank arm is placed between the first clamping seat and the second clamping seat, the latch is moved to connect with the locking seat, thereby locking the first clamping seat and the second clamping seat. The locking method of the latch and the locking seat facilitates locking and unlocking, shortens the locking and unlocking time, and thus improves assembly efficiency.

[0016] Optionally, the support assembly includes a first support base and a second support base, both of which are connected to the base; the first support base is used to support the isolation crank arm, and the second support base is used to support the isolation insulating pull rod.

[0017] By adopting the above technical solution, the isolation crank arm is supported by the first support base and the insulating tie rod is supported by the second support base, which can stabilize the position of the isolation crank arm, reduce the possibility of the isolation crank arm moving during the assembly process, and enable the isolation spindle to pass smoothly through multiple isolation crank arms, thereby improving assembly efficiency.

[0018] Optionally, the second support base is provided with a support groove, which is adapted to the shape of the isolation and insulation tie rod.

[0019] By adopting the above technical solution, the support groove can limit the position of the insulating tie rod, further improving the support stability of the second support seat.

[0020] Optionally, the first clamping seat is provided with a first clamping groove, and the second clamping seat is provided with a second clamping groove. The first clamping groove and the second clamping groove respectively abut against the end of the isolation crank arm connected to the isolation spindle to clamp the isolation crank arm.

[0021] By adopting the above technical solution, the first clamping groove and the second clamping groove cooperate to press the end of the isolation crank arm connected to the isolation main shaft together, thereby fixing the isolation crank arm.

[0022] Optionally, the first clamping seat is provided with a guide groove, and a first guide block is provided in the guide groove; the second clamping groove is provided with a second guide block, and the first guide block and the second guide block guide the isolation spindle to pass through the isolation crank arm.

[0023] By adopting the above technical solution, after the connecting block is clamped by the first clamping groove and the second clamping groove, when the isolation spindle passes through the isolation crank arm, the first guide block and the second guide block can reduce the possibility of the isolation spindle shifting during the movement, guide the isolation spindle to pass smoothly through the mounting hole, and improve the reliability of the assembly.

[0024] Optionally, the pushing device includes a pushing drive and a connecting seat, the connecting seat being detachably connected to the base plate, and the pushing drive being connected to the connecting seat.

[0025] By adopting the above technical solution, the connecting seat is detachably connected to the base, allowing the position of the push drive component to be adjusted. This enables the length adjustment of the isolation spindle inserted into the isolation crank arm, meeting different assembly requirements and improving the versatility and flexibility of the tooling.

[0026] Optionally, the base includes a base plate and a connecting plate, the connecting plate being detachably connected to the base plate, and multiple connecting plates being provided, with each of the multiple fixing devices corresponding to one another on the connecting plate.

[0027] By adopting the above technical solution, multiple connecting plates are provided. Since the connecting plates are detachably connected to the base plate, the distance between two adjacent isolation crank arms can be adjusted, which can meet different assembly requirements and improve the versatility of the tooling.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The support assembly ensures the isolation crank arm is stably placed on the first clamping seat, improving the stability of the isolation crank arm installation. After the isolation crank arm is placed between the first and second clamping seats, the locking device locks the first and second clamping seats, thereby fixing the end of the isolation crank arm connected to the isolation spindle. This reduces the possibility of the isolation crank arm moving when the pushing device pushes the isolation spindle through multiple isolation crank arms, improving assembly efficiency.

[0030] 2. By supporting the isolation crank arm with the first support base and the insulating tie rod with the second support base, the position of the isolation crank arm can be stabilized, reducing the possibility of the isolation crank arm moving during assembly, allowing the isolation spindle to pass smoothly through multiple isolation crank arms, thus improving assembly efficiency.

[0031] 3. After the connecting block is clamped by the first clamping groove and the second clamping groove, when the isolation spindle passes through the isolation crank arm, the first guide block and the second guide block can reduce the possibility of the isolation spindle shifting during the movement, guide the isolation spindle to pass smoothly through the mounting hole, and improve the reliability of the assembly.

[0039] The following is in conjunction with the appendix Figure 2 - Appendix Figure 6 This application will be described in further detail.

[0040] Example 1

[0041] Embodiment 1 of this application discloses an isolated spindle assembly fixture. For example... Figure 2 As shown, the assembly fixture includes a base 1, a fixing device 2, a placement rack 3, and a pushing device 4.

[0042] like Figure 2 As shown, the base 1 includes a base plate 11 and a connecting plate 12. The base plate 11 has multiple mounting grooves 111. The connecting plate 12 is detachably connected to the base plate 11. Specifically, the connecting plate 12 has several through holes, which facilitate the installation of tightening bolts. The tightening bolts tighten the inner wall of the mounting grooves 111 to fix the connecting plate 12.

[0043] like Figure 3 and Figure 4 As shown, the fixing device 2 includes a clamping assembly 21 and a support assembly 22. In this embodiment 1, a total of three support assemblies 22 are installed. The support assembly 22 includes a first support base 221 and a second support base 222. The first support base 221 is fixedly connected to the connecting plate 12, and the second support base 222 is fixedly connected to the connecting plate 12. A support groove 2221 is provided on the second support base 222. The support groove 2221 is adapted to the shape of the isolation and insulating pull rod 7. The support groove 2221 can restrict the movement of the isolation and insulating pull rod 7, thereby improving the stability of supporting the isolation and insulating pull rod 7. By supporting the isolation crank arm 6 with the first support base 221 and the isolation and insulating pull rod 7 with the second support base 222, the possibility of the isolation crank arm 6 moving during the assembly process is reduced, thereby improving the reliability of the isolation spindle 5 passing smoothly through multiple isolation crank arms 6 and improving assembly efficiency.

[0044] like Figure 3 and Figure 4 As shown, the clamping assembly 21 includes a first clamping seat 211, a second clamping seat 212, and a locking member 213. The locking member 213 includes a latch 2131 and a locking seat 2132. The locking seat 2132 is mounted on the first clamping seat 211, and the latch 2131 is mounted on the second clamping seat 212. Specifically, the first clamping seat 211 includes a pair of first clamping blocks 2114 and second clamping blocks 2115, both of which are fixedly connected to the connecting plate 12. A first clamping groove 2111 is formed on the first clamping block 2114, and a guide groove 2112 is formed on the second clamping block 2115. A second clamping groove 2121 is formed on the second clamping seat 212, wherein the shapes of the first clamping groove 2111 and the second clamping groove 2121 are adapted to the shape of the connecting block 61.

[0045] like Figure 1 and Figure 4 As shown, when installing the isolation arm 6, the isolation arm 6 is positioned between the two first clamping blocks 2114. Simultaneously, the connecting blocks 61 on both sides of the isolation arm 6 are placed within the first clamping grooves 2111 of the two first clamping blocks 2114. When installing the second clamping seat 212, the first clamping grooves 2111 and 2121 cooperate, respectively abutting against the sides of the connecting blocks 61, thereby limiting the position of the connecting blocks 61. After the second clamping seat 212 is installed, the latch 2131 and the lock seat 2132 are connected, causing the first clamping grooves 2111 and 2121 to abut against the connecting blocks 61, thereby fixing the isolation arm 6 and reducing the possibility of movement of the isolation arm 6 during assembly.

[0046] In addition, such as Figure 4 and Figure 5 As shown, a first guide block 2113 is fixedly connected in the guide groove 2112, and a second guide block 2122 is fixedly connected in the second clamping groove 2121 at the position corresponding to the first guide block 2113. Both the first guide block 2113 and the second guide block 2122 are provided with inclined surfaces. When the isolation spindle 5 passes through the first guide block 2113 and the second guide block 2122, the inclined surfaces on the first guide block 2113 and the second guide block 2122 can guide the movement direction of the isolation spindle 5, so that the isolation spindle 5 can smoothly pass through the mounting hole 62.

[0047] like Figure 2 As shown, in this embodiment 1, a placement frame 3 is installed, which is used to place the isolation spindle 5. The placement frame 3 is also provided with through holes for installing tightening bolts, thereby realizing the detachable connection between the placement frame 3 and the base plate 11, which facilitates the adjustment of the placement position of the isolation spindle 5 and further improves the assembly flexibility.

[0048] like Figure 2 As shown, the pushing device 4 includes a pushing drive component 41 and a connecting seat 42. The connecting seat 42 is detachably connected to the base plate 11, and the body of the pushing drive component 41 is fixedly connected to the connecting seat 42. Preferably, the pushing drive component 41 is an electric push rod. Specifically, the connecting seat 42 has a through hole for installing a tightening bolt, thereby enabling the disassembly and fixing of the pushing drive component 41. The detachable connection of the connecting seat 42 allows the pushing drive component 41 to move, facilitating the adjustment of the length of the isolation spindle 5 inserted into the isolation crank arm 6 by adjusting the position of the pushing drive component 41.

[0049] The implementation principle of the isolation spindle assembly fixture in Embodiment 1 of this application is as follows:

[0050] When assembling the isolation spindle 5 and the isolation crank arm 6, first adjust the positions of the connecting plate 12, the placement bracket 3 and the connecting seat 42.

[0051] After adjusting the connecting plate 12, the placement bracket 3, and the connecting seat 42 to their designated positions, place the isolation crank arm 6 on the first support seat 221 and the isolation insulating pull rod 7 on the second support seat 222. Simultaneously, place the connecting block 61 of the isolation crank arm 6 into the first clamping groove 2111. After the isolation crank arm 6 is stably positioned, install the second clamping seat 212, ensuring the connecting block 61 is located within the second clamping groove 2121. After installing the second clamping seat 212, connect the latch 2131 to the lock seat 2132, locking the first clamping seat 211 and the second clamping seat 212, thereby fixing the isolation crank arm 6.

[0052] After placing the isolation spindle 5 on the mounting bracket 3, adjust the position of the isolation spindle 5 so that the end face of the isolation spindle 5 abuts against the end face of the output end of the drive member 41. At this time, move the output end of the drive member 41 to push the isolation spindle 5 into the isolation crank arm 6.

[0053] After the isolation spindle 5 moves a specified distance, the assembly of the isolation spindle 5 and multiple isolation crank arms 6 is completed.

[0054] Example 2

[0055] The difference between Example 2 and Example 1 is as follows:

[0056] like Figure 6 As shown, multiple connecting plates 12 are provided in this embodiment 2. Each connecting plate 12 is fixedly connected to a first clamping seat 211, a first support seat 221, and a second support seat 222. Each first clamping seat 211 is correspondingly equipped with a second clamping seat 212 and a locking member 213. Several through holes are opened on the connecting plate 12 for installing tightening bolts. The tightening bolts realize the detachable connection of each connecting plate 12, so that the position of each connecting plate 12 can be adjusted on the base plate 11. By adjusting the spacing between adjacent connecting plates 12, the spacing between each isolation crank arm 6 can be adjusted, thereby meeting different assembly requirements and improving the versatility of the assembly tooling.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
