Detailed implementation manners

[0043] The following further describes the present application in detail with reference to the Figures 1-7 accompanying drawings.

[0044] An embodiment of the present application discloses a pole-mounted switch test bench. Referring to Figure 3 , the pole-mounted switch test bench includes a test bench body 5, a clamping unit 7, and an insertion unit 8. The middle of the test bench body 5 is recessed to form a test space 6 for placing the pole-mounted switch to be tested. The clamping unit 7 and the insertion unit 8 are respectively installed on the test bench body 5 and are located on opposite sides of the test space 6. The clamping unit 7 is responsible for clamping the outgoing line ends of the pole-mounted switch simultaneously, while the insertion unit 8 is responsible for inserting the aviation plug connector 4 of the pole-mounted switch. These two units jointly form an electrical cooperation between the pole-mounted switch and the test equipment to perform a resistance test on the pole-mounted switch.

[0045] Referring to Figure 3 and Figure 4 , wherein, when the pole-mounted switch is sent into the test bench body 5, it is hung on a transport trolley and brought to the test space 6 by the transport trolley. The transport trolley is in a square frame form, with a space for placing the pole-mounted switch formed in the middle and walking wheels at the bottom. Combining Figure 2 , when the pole-mounted switch is hung on the transport trolley, it is in the inverted state as shown, so that the upper outgoing line 2 of the pole-mounted switch is below the lower outgoing line 3 of the pole-mounted switch. When the pole-mounted switch is located in the test space 6, multiple encapsulated pole columns 1 on the pole-mounted switch are distributed along the length direction of the first workbench 51.

[0046] Referring to Figure 3, for the test bench body 5, the test space 6 penetrates through the opposite ends of the test bench body 5, separating the test bench body 5 into opposite first workbench 51 and second workbench 52, and there is a support table 53 between the first workbench 51 and the second workbench 52. The upper surface of the support table 53 is the bottom surface of the test space 6. Both the first workbench 51 and the second workbench 52 are of square structure. The direction in which the test space 6 penetrates through the two ends of the test bench body 5 is the length direction of the first workbench 51, the second workbench 52, and the support table 53. There are openings in the middle and on the mutually facing sides inside the first workbench 51 and the second workbench 52, and the test equipment is placed in the cavities of the first workbench 51 and the second workbench 52.

[0047] Referring to Figure 3 and Figure 5 , for the clamping unit 7, the clamping unit 7 is installed on the first workbench 51. The clamping unit 7 includes an upper clamping device 71 and a lower clamping device 72 located in the test space 6. The upper clamping device 71 is used to clamp the upper outgoing wire 2 on the pole-mounted switch, and the lower clamping device 72 is used to clamp the lower outgoing wire 3 on the pole-mounted switch. Both the upper clamping device 71 and the lower clamping device 72 include a base beam 9, a connecting beam 10, a fixture 11, and a driving source 12.

[0048] Referring to Figure 3 and Figure 6 , taking the upper clamping device 71 as an example, the number of base beams 9 is two. Both of the two base beams 9 are installed on the side of the first workbench 51 facing the second workbench 52 to support the connecting beam 10, and the distribution direction of the two base beams 9 is parallel to the length direction of the first workbench 51. A guiding groove 13 that is recessed inward and extends along the width direction of the first workbench 51 is formed on the base beam 9. The connecting beam 10 has a guiding portion 14 that slides in the guiding groove 13. The cross-section of the guiding groove 13 is wedge-shaped, and the guiding portion 14 is in the shape of a wedge block adapted to the guiding groove 13. The connecting beam 10 slides on the base beam 9 along the length direction of the guiding groove 13 through the cooperation of the guiding portion 14 and the guiding groove 13.

[0049] Referring to Figure 3 and Figure 5 , the connecting beam 10 is in the shape of a long strip. The length extension direction of the connecting beam 10 is perpendicular to the length extension direction of the guiding groove 13. There are multiple fixtures 11. The multiple fixtures 11 are installed on the connecting beam 10 along the length direction of the connecting beam 10, and the number and positions of the fixtures 11 in the upper clamping device 71 correspond one-to-one with the upper outgoing wires 2 of the pole-mounted switch to be clamped to the corresponding upper outgoing wires 2. The fixture 11 is a fixture 11 with a cylinder so that the jaws of the fixture 11 can be automatically driven to clamp and release. At the same time, the jaws of the fixture 11 can conduct electricity, and the jaws of the fixture 11 are electrically connected to the test equipment through wires (not shown in the figure). Thus, when the fixture 11 is clamped to the upper outgoing wire 2, the upper outgoing wire 2 is electrically connected to the test equipment.

[0050] Similarly, the number and positions of the clamps 11 in the lower clamping device 72 correspond one-to-one with the lower outgoing lines 3 of the pole-mounted switch, for clamping onto the corresponding lower outgoing lines 3. And when the clamp 11 clamps onto the lower outgoing line 3, the lower outgoing line 3 is in telecommunication connection with the test equipment.

[0051] The driving source 12 is a device capable of automatic telescoping. In this embodiment, it is a cylinder, and in other embodiments, it can also be an electric telescopic rod. The base of the driving source 12 is fixed to the base beam 9. The telescoping direction of the output end of the driving source 12 for telescoping is parallel to the length direction of the guiding groove 13, and a connecting rod 21 connected to the output end of the driving source 12 through a connecting piece 20 is fixed to the connecting beam 10, so that the output end of the driving source 12 can drive the connecting beam 10 to move towards or away from the second workbench 52.

[0052] Refer to Figure 3 and Figure 5 As shown in FIGS. and, when the driving sources 12 of the upper clamping device 71 and the lower clamping device 72 move simultaneously, when the output ends of the driving sources 12 extend, they drive the connecting beam 10 and the clamp 11 to move towards the second workbench 52, so that the upper outgoing line 2 of the pole-mounted switch enters the jaws of the clamp 11 of the upper clamping device 71, and the lower outgoing line 3 enters the jaws of the clamp 11 of the lower clamping device 72. And at this time, the jaws of the clamp are separated from each other. Then, the clamp 11 further pushes its own jaws towards each other to clamp the corresponding upper outgoing line 2 or lower outgoing line 3.

[0053] Adaptively, according to the distribution positions of the upper outgoing line 2 and the lower outgoing line 3 on the pole-mounted switch, the base beam 9 in the upper clamping device 71 is located above the base beam 9 of the lower clamping device 72; the connecting beam 10 in the upper clamping device 71 is closer to the first workbench 51 than the connecting beam 10 in the upper clamping device 71; and the jaws of the clamp 11 in the upper clamping device 71 move horizontally for clamping, while the jaws of the clamp 11 in the lower clamping device 72 move vertically for clamping.

[0054] Refer to Figure 3 and Figure 6 As shown in FIGS. and, further, in order to improve the adaptability of the upper clamping device 71 and the lower clamping device 72, a first adjustment groove 22 extending vertically is formed on the surface of the first workbench 51 close to the second workbench 52. The cross-section of the first adjustment groove 22 is in the shape of a dovetail. A first adjustment seat 23 is connected to the base beam 9. The first adjustment seat 23 has a part extending into the first adjustment groove 22 and capable of moving up and down in the first adjustment groove 22. And a bolt that can be screwed into the first adjustment groove 22 and abut against the inner wall of the first adjustment groove 22 is provided on the first adjustment groove 22, so as to position the base beam 9 relative to the first workbench 51 through the frictional force between the bolt and the inner wall of the first adjustment groove 22, thereby enabling both the upper clamping device 71 and the lower clamping device 72 to adjust their heights vertically.

[0055] Furthermore, a second adjustment groove 24 is formed in the connecting beam 10 along the extending direction of its own length. The cross-section of the second adjustment groove 24 is in the shape of a dovetail. A second adjustment seat 25 is connected to the fixture 11. The second adjustment seat 25 has a bolt that extends into the second adjustment groove 24 and can be tightened against the second adjustment groove 24. The fixture 11 can be adjusted in position along the length direction of the connecting beam 10 through the cooperation of the second adjustment groove 24 and the second adjustment seat 25, and the fixture 11 is positioned on the connecting beam 10 by tightening the bolt against the second adjustment groove 24, so as to be able to adjust the distance between two adjacent fixtures 11, further improving the adaptability between the upper clamping device 71 and the lower clamping device 72.

[0056] Referring to Figure 3 , for the insertion unit 8, the insertion unit 8 includes an insertion head 81 and a power source 82. The insertion head 81 is placed on the top of the second workbench 52. The connector of the testing device extends and is fixed into the insertion head 81, and the socket of the connector of the testing device is exposed on the side of the insertion head 81 facing the first workbench 51. The power source 82 is a device capable of automatic telescoping. In this embodiment, it is a cylinder, and in other embodiments, it can also be an electric telescopic rod. The output end of the power source 82 for telescoping is connected to the insertion head 81 to drive the insertion head 81 to move along the width direction of the second workbench 52.

[0057] When the output end of the power source 82 extends, it drives the insertion head 81 to move towards the first workbench 51, so that the connector of the testing device on the insertion head 81 can be inserted and mated with the aviation plug connector 4 of the pole-mounted switch, so as to electrically connect the aviation plug connector 4 of the pole-mounted switch with the testing device. When the output end of the power source 82 retracts, it drives the insertion head 81 to move away from the first workbench 51, so that the connector of the testing device leaves the aviation plug connector 4.

[0058] Referring to Figure 3 and Figure 5 , in addition, in order to enable the transport cart to quickly align with the fixture 11 and the insertion head 81 when driving the pole-mounted switch to move into the testing space 6, a slide rail 15 located in the testing space 6 is fixed on the upper surface of the support table 53. The slide rail 15 extends along the length direction of the support table 53. The slide rail 15 and the support table 53 together enclose a guide groove for the running wheels of the transport cart to roll. When the running wheels of the transport cart run in the guide groove of the slide rail 15, the position of the pole-mounted switch on the support table 53 in the width direction is limited.

[0059] Further, a positioning pin 16 is slidably positioned in the cavity of the second workbench 52 along the width direction of the second workbench 52. The positioning pin 16 penetrates through the side of the second workbench 52 close to the first workbench 51 and enters the testing space 6. In this embodiment, a slot 26 for the positioning pin 16 to be inserted is provided on the side wall of the transport cart.

[0060] Referring to Figure 3 and Figure 7, when the transport cart moves along the slide rail 15 to a position where the slot 26 is opposite to the positioning pin 16, moving the positioning pin 16 towards the first workbench 51 can enable the positioning pin 16 to be inserted into the slot 26, so as to limit the position of the pole-mounted switch in the length direction on the support table 53. It should be noted that at this time, the upper outgoing line 2 and the lower outgoing line 3 of the pole-mounted switch are both opposite to the corresponding fixture 11, and the aviation plug connector 4 is opposite to the plug-in head 81, so that the pole-mounted switch can be quickly positioned at the test position through the slide rail 15 and the positioning pin 16.

[0061] Among them, in order to improve the stability of the positioning pin 16 and the convenience of operation, the positioning pin 16 is provided with an elastic member 17 and a foot pedal member 19. Specifically, the elastic member 17 is a spring, the spring is coaxially sleeved on the outer wall of the positioning pin 16, and one end of the spring is connected to the inner wall of the second workbench 52. There is a protrusion protruding from the outer wall of the positioning pin 16 on the outer wall of the positioning pin 16, and the relatively other end of the spring is connected to the protrusion of the positioning pin 16. The elastic force of the spring gives the positioning pin 16 a tendency to move towards the first workbench 51, so that the positioning pin 16 remains in the inserted state when inserted into the transport cart.

[0062] The foot pedal member 19 includes a pedal 191 and a hinge rod 192. The pedal 191 successively has a hinge portion 1911, a rotating portion 1912 and a stepping portion 1913 along the direction away from the first workbench 51. The two ends of the hinge rod 192 away from each other are respectively hinged to the hinge portion 1911 and the end of the positioning pin 16 away from the first workbench 51 through a pin shaft. A rotating shaft 18 is fixedly connected to the inner wall of the second workbench 52 through a seat body, and the axis direction of the rotating shaft 18 is parallel to the length direction of the second workbench 52. The rotating portion 1912 is rotatably sleeved on the outer wall of the rotating shaft 18.

[0063] When the positioning pin 16 is inserted into the transport cart, by stepping on the stepping portion 1913 downward, the pedal 191 can be driven to rotate, so as to drive the positioning pin 16 to move away from the first workbench 51 to disengage from the transport cart through the hinge rod 192, so that the transport cart can leave the support table 53. Further, a limiting block 27 is fixed on the inner bottom wall of the second workbench 52. The limiting block 27 is located below the stepping portion 1913. When the stepping portion 1913 abuts against the limiting block 27, the hinge rod 192 can disengage from the transport cart to limit the excessive rotation of the pedal 191.

[0064] The implementation principle of the pole-mounted switch test bench in the embodiment of the present application is as follows: The transport cart drives the pole-mounted switch to move into the test space 6, and the transport cart is positioned at the test position of the pole-mounted switch through the slide rail 15 and the positioning pin 16. Then the driving source 12 and the power source 82 are started together to drive the fixture 11 to clamp the corresponding upper outgoing line 2 and lower outgoing line 3, and the plug-in head 81 is inserted into the aviation plug connector 4 to quickly electrically connect the pole-mounted switch with the corresponding test equipment.

[0065] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
