Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical engineering, and in particular to a copper busbar connection device for testing low-voltage complete sets of equipment. Background Technology
[0002] Low-voltage switchgear requires low-voltage testing before leaving the factory or before product finalization. During testing, the low-voltage switchgear needs to be electrically connected to the test power supply via copper busbars. However, the connecting copper busbars weigh several hundred kilograms, making them difficult to lift manually. Therefore, they are usually lifted using a gantry crane, and then the angle and position are manually adjusted. One end is electrically connected to the copper busbar of the test power supply, and the other end is inserted into the low-voltage switchgear.
[0003] However, this method has the problem that the position control of the gantry crane is not precise. After the copper busbar is lifted, it is in a state of suspended swinging. It requires manual support for fine-tuning of its position, which is time-consuming and labor-intensive. In addition, there is no fixed structure, which makes the copper busbar not stable enough.

[0020] To make the purpose, technical solution and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and examples.
[0021] Example 1
[0022] like Figure 1The copper busbar connection device for testing low-voltage complete equipment shown includes a lifting device 1, a vertical lead screw 101, a first rotating mechanism 102, an internal threaded sleeve 103, a connecting rod 104, a frame bracket 2, a front-to-back moving device 3, a first base 301, a first slide rail 302, a first slider 303, a first fixing block 304, a longitudinal lead screw 305, a first moving block 306, a front-to-back sliding plate 307, a first rotating wheel 308, a left-to-right moving device 4, a second slide rail 401, a second slider 402, a left-to-right sliding plate 403, a second moving block 404, a second fixing block 405, a transverse lead screw 406, a second rotating wheel 407, a rotating device 5, a support frame 501, an insulating roller 502, a first gear 503, a second gear 504, a second rotating mechanism 505, a copper busbar 6, a roller 7, and a base 8.
[0023] The base 8 has rollers 7 installed at the four corners of its bottom surface and a frame bracket 2 fixed on its top surface. The frame bracket 2 is connected to a lifting device 1 at both the front and rear ends. The lifting device 1 is equipped with a front-to-back moving device 3, and the front-to-back moving device 3 is equipped with a left-to-right moving device 4. The left-to-right moving device 4 is equipped with a rotating device 5. Three copper busbars 6 pass through and are fixed on the rotating device 5. Both ends of the three copper busbars 6 are exposed outside the rotating device 5, and each copper busbar 6 has a straight end at one end and an L-shaped end at the other end.
[0024] In this way, the lifting device 1 can drive the three copper busbars 6 to rise and fall, the forward and backward moving device 3 can drive the three copper busbars 6 to move forward and backward, the left and right moving device 4 can drive the three copper busbars 6 to move left and right, and the rotating device 5 can realize the rotation of the three copper busbars 6, thereby realizing angle adjustment.
[0025] When copper busbars need to be connected, the rollers 7 push the entire device between the low-voltage switchgear and the three busbars of the power supply. Then, the lifting device moves the forward and backward movement device 3, the left and right movement device 4, the rotating device 5, and the three copper busbars 6 together until they reach the height of the electrical sockets of the low-voltage switchgear. The forward and backward movement device 3, the left and right movement device 4, and the rotating device 5 then align the straight ends of the copper busbars 6 with the sockets, and so on. Figure 3 As shown, the L-shaped end of the copper busbar 6 corresponds to the three busbars of the power supply. Finally, the left and right moving device 4 drives the copper busbar 6 so that its straight end is inserted into the electrical connection port of the low-voltage complete set of equipment, and the L-shaped end of the copper busbar 6 is electrically connected to the three busbars of the power supply.
[0026] The lifting device 1 includes a vertical lead screw 101, with a first rotating mechanism 102 fixed to the base 8 at the bottom and a top rotatably connected to the frame bracket 2. An internal threaded sleeve 103 is threadedly connected to the vertical lead screw 101, and the two sides of the internal threaded sleeve 103 are connected to the front and rear moving devices 3 via connecting rods 104. The first rotating mechanism 102 is a motor.
[0027] In this way, the motor drives the vertical lead screw 101 to rotate, which in turn drives the first base 301 of the front and rear moving device 3 to rise and fall through the internal threaded sleeve 103 and the connecting rod 104.
[0028] The forward and backward moving device 3 includes a first base 301 connected to the lifting device 1. The first base 301 has a first slide rail 302 fixed at both ends. A first slider 303 is slidably connected to the first slide rail 302. A forward and backward sliding plate 307 is fixedly connected to the top of the first slider 303. A first fixing block 304 is fixed at both the front and rear ends of the top surface of the first base 301. A first moving block 306 is fixedly connected to the middle of the bottom of the forward and backward sliding plate 307. A longitudinal lead screw 305 is rotatably connected to the first fixing block 304. The first moving block 306 is threadedly connected to the longitudinal lead screw 305. A first rotating wheel 308 is fixedly connected to one end of the longitudinal lead screw 305.
[0029] The left and right moving device 4 includes a second slide rail 401 fixed to the front and rear ends of the front and rear slide plates 307 respectively. A second slider 402 is slidably connected to the second slide rail 401. A left and right slide plate 403 is fixedly connected to the top of the second slider 402. A second moving block 404 is fixedly connected to the middle of the bottom of the left and right slide plates 403. A second fixing block 405 is fixed to the left and right ends of the middle of the top surface of the front and rear slide plates 307. A transverse lead screw 406 is rotatably connected to the second fixing block 405. The second moving block 404 is threadedly connected to the transverse lead screw 406. A second rotating wheel 407 is connected to one end of the transverse lead screw 406.
[0030] By rotating the first rotating wheel 308, the longitudinal lead screw 305 is driven to rotate, which in turn drives the front and rear sliding plates 307 to move back and forth through the first moving block 306. Similarly, by rotating the second rotating wheel 407, the left and right sliding plates 403 can be driven to move left and right.
[0031] The rotating device 5 includes a support frame 501 fixed on both sides of the left and right sliding plates 403. An insulating roller 502 is rotatably connected to the support frame 501. The middle parts of the three copper busbars 6 are fixed inside the insulating roller 502. A first gear 503 is fixed to the outer periphery of the insulating roller 502. The first gear 503 meshes with a second gear 504. The second gear 504 is connected to a second rotating mechanism 505 fixed on the left and right sliding plates 403. The second rotating mechanism 505 is a stepper motor.
[0032] In this way, the stepper motor can drive the insulating roller 502 to rotate, which in turn drives the three copper busbars 6 to rotate, thereby fine-tuning the angle of the copper busbars.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the essence and scope of the technical solution of this utility model.
