Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1 to 4 In this embodiment, a pantograph static tension detector includes a base 1, a tension display module 2 fixedly installed on the outside of the base 1, two vertical poles 3 fixedly connected to the top of the base 1, and a mounting plate 4 fixedly connected to the top of the two vertical poles 3. A tension detection structure 5 is provided on the top of the base 1, a fixing mechanism 6 extending to the outside of the base 1 is provided inside the base 1, and an adjustment mechanism 7 for raising and lowering the tension detection structure 5 is provided on the top of the base 1. The tension detection structure 5 includes a tension meter 51 and a hook 52 fixedly installed on the bottom of the tension meter 51; the fixing mechanism 6 includes a forward and reverse motor 61, a bidirectional screw 62, a threaded block 63, a mounting seat 64, a fixing seat 65, an electric push rod 66 and a clamp 67.

[0026] The forward / reverse motor 61 is fixedly mounted on the outside of the base 1, and the bidirectional lead screw 62 is fixedly connected to the output shaft of the forward / reverse motor 61 and extends into the interior of the base 1. The bidirectional lead screw 62 is rotatably connected to the interior of the base 1. The tension display module 2 activates the forward / reverse motor 61 to rotate the bidirectional lead screw 62, causing the threaded block 63 to move the fixing base 65 left and right. The electric push rod 66 is then activated to extend and retract, driving the clamp 67 downward. This facilitates the rapid fixing and release of the pantograph body, prevents the pantograph body from deflecting during detection, improves detection accuracy, and achieves the advantage of high detection accuracy.

[0027] Specifically, the threaded block 63 is threadedly connected to the outside of the bidirectional screw 62, and the mounting seat 64 is fixedly connected to the top of the threaded block 63. There are two threaded blocks 63 and two mounting seats 64. The two threaded blocks 63 are symmetrically distributed on the outside of the bidirectional screw 62.

[0028] It should be noted that the fixing base 65 is fixedly connected to the top of the mounting base 64, the electric push rod 66 is fixedly mounted on the upper surface of the fixing base 65 and extends into the interior thereof, and the clamp 67 is fixedly connected to the output end of the electric push rod 66.

The provision of the guide rods 68 improves the stability of the threaded blocks 63 during linear displacement.

[0029] In this embodiment, the adjustment mechanism 7 comprises a reduction motor 71, a winding roller 72, a suspension rope 73, a suspension ring 74, and a connecting plate 75. The reduction motor 71 is fixedly mounted on the top of the mounting plate 4, the winding roller 72 is fixedly connected to the output shaft of the reduction motor 71, the suspension rope 73 is wound around the outside of the winding roller 72 and fixed to its center, the suspension ring 74 is fixedly connected to the end of the suspension rope 73 away from the winding roller 72, and the connecting plate 75 is fixedly connected to the bottom of the suspension ring 74. The reduction motor 71 is activated by the tension display module 2 to rotate the winding roller 72, so that the suspension rope 73 drives the connecting plate 75 and the tension detection structure 5 upward through the suspension ring 74 to perform static tension detection.

[0030] The connecting plate 75 has a limiting hole inside that matches the vertical pole 3 . The connecting plate 75 is slidably connected to the outside of the vertical pole 3 . The tensile gauge 51 is fixedly installed on the bottom of the connecting plate 75 .

[0031] The working principle of the above embodiment is:

[0032] During use, the forward and reverse motors 61 are started through the tension display module 2 to drive the bidirectional lead screw 62 to rotate, so that the threaded block 63 drives the fixing seat 65 to move left and right, and then the electric push rod 66 is started to extend and retract to drive the clamp 67 to move downward, so as to quickly fix the pantograph body. The pantograph body can be lifted through the hook 52, and the reduction motor 71 is started through the tension display module 2 to drive the winding roller 72 to rotate, so that the lifting rope 73 drives the connecting plate 75 and the tension detection structure 5 to move upward through the lifting ring 74 to perform static tension detection, and the measurement results are displayed in real time through the tension display module 2.

[0034] Any connection method can be implemented as long as it can achieve its beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so its specific structural composition and working principle will not be described in detail in this embodiment.
