[0014] As shown in the figure, a temperature rise test vehicle for a large current copper busbar is provided with a frame 1 composed of a longitudinal and a transverse frame fixedly connected, and running wheels 2 are respectively installed at four corners of the bottom of the frame 1. The frame 1 can move and walk through the running wheels 2, and the position can be adjusted according to the specification and length of the busbar product; four vertically upward pillars 3 are arranged above the frame, and a crossbeam is arranged between the pillars at both ends. A plurality of spaced limiting vertical rods 9 are arranged above the crossbeam, and the space between each limiting vertical rod and the adjacent limiting vertical rod forms a series of positioning notches that can position and clamp the busbar 15, and the two ends of the busbar 15 can be inserted from top to bottom along the positioning notches.

[0015] A lifting platform 5 is arranged in the middle of the frame, and the two ends of the lifting platform 5 are respectively installed on the first vertical guide rail 12. The first vertical guide rail 12 is a cylindrical linear guide rail. The slider matched with the cylindrical linear guide rail is relatively small in size and occupies less space. The first vertical guide rail 12 is installed on the inner side surfaces opposite to each other of the pillars 3 at both ends of the same side of the frame, which further saves space. An electric lifting mechanism 10 is respectively arranged below the two ends of the lifting platform 5, and walking wheels are installed at the four corners of the bottom frame of the frame. A supporting frame is arranged above the bottom frame. The electric lifting mechanism 10 is fixedly installed above the supporting frame. A lifting motor 7 is installed at a position located in the middle of the supporting frame. The two ends of the output shaft 6 of the lifting motor 7 are respectively connected to the electric lifting mechanism 10. The lifting motor drives the electric lifting mechanism to drive the lifting platform to move up and down along the first vertical guide rail. The two ends of the busbar can fall on the lifting platform from top to bottom along the positioning slot, and the electric lifting mechanism drives the lifting platform to push the busbar 15 up and down to meet the test height requirements.

[0016] The trolley moves on its wheels to adjust the distance, and the lifting platform moves up and down to adjust the height, which can adapt to the detection and connection operation requirements of different equipment.

[0017] Furthermore, support seats 11 are respectively arranged at positions outside both sides of the first-layer lifting platform at both ends of the support frame, and second vertical guide rails 14 are respectively installed above each support seat 11. A transverse support plate 8 is arranged between the second vertical guide rails 14 on both sides of the same end of the frame, forming a two-layer lifting platform that can support the dual-channel busbar 15 in layers. The second vertical guide rail 14 is connected to a hand-cranked lifting mechanism 13, and the transverse support plate is driven up and down by the hand-cranked lifting mechanism 13; the first-layer lifting platform and the second-layer lifting platform can be used at the same time to support dual-channel large current testing. Using the first-layer lifting platform or the second-layer lifting platform alone can support single-channel small current testing, which is easy to operate.

[0018] Furthermore, a plurality of spacing limit vertical rods are also provided in the middle of the support frame to improve the stability of the clamping busbar.

[0019] The limit pole 9 adopts an insulating pole, which is safe and reliable.

[0020] Furthermore, the limiting vertical rod 9 can be moved laterally to adjust the width of the positioning slot, and can clamp the busbar so that the busbar remains upright, which is convenient for connecting the test equipment.

[0021] The present invention is used for a temperature rise test vehicle for a large current copper busbar. The first-layer lifting platform and the second-layer lifting platform can simultaneously support a dual-channel large current test, or independently support a single-channel small current test. The two-layer lifting platforms are driven by a lifting motor and a hand-cranked lifting mechanism respectively, and can meet the test height adjustment requirements of busbars of different width specifications. The limit vertical rod moves laterally to adjust the width of the positioning notch, and can clamp the busbar so that the busbar remains upright, which is convenient for connecting the test equipment. The frame moves by means of traveling wheels, and the position is adjusted according to the specification length of the busbar product, so as to meet the temperature rise test requirements of busbars of different lengths and widths. The handling and connection operations are convenient, and the detection efficiency is improved.

[0024] It adopts a two-layer lifting platform structure, the lower layer is an electric screw drive lifting mechanism, and the upper layer is a hand-cranked screw lifting mechanism, which meets the height adjustment requirements of test busbars of different width specifications.

[0025] The insulating rod can be moved left and right to clamp the test busbar to keep the busbar upright.

[0026] It adopts an overall moving method, and the placement position can be flexibly adjusted according to the specifications and length of the busbar products.
