[0020] See also Figure 1-5 The utility model provides a technical solution: a portable pantograph detection auxiliary device, including a pantograph detector 1, a groove is opened on the lower end surface of the pantograph detector 1, and fixing plates 5 are respectively provided at both ends of the groove on the pantograph detector 1, rotating rods 3 are inserted between the fixing plates 5, and the rotating rods 3 are respectively provided with multiple groups of rollers 4 on the outer wall, first clamping rods 6 are respectively inserted on the fixing plates 5, and the other end of the first clamping rod 6 is inserted on the rotating rod 3, the upper end of the first clamping rod 6 is connected to the pulling plate 8, and the lower end surface of the pulling plate 8 is provided with a first spring 7, and the other end of the first spring 7 is connected to the upper end surface of the fixing plate 5.

[0021] Furthermore, the rotating rod 3 forms a locking limit structure with the fixed plate 5 through the pull plate 8, the first spring 7, the first locking rod 6, and the fixed plate 5, and the roller 4 forms a rotating structure with the pantograph detector 1 in the groove 2 through the rotating rod 3, so that the pantograph detector 1 can be easily moved through the roller 4 while avoiding the roller 4 from affecting the stability of the pantograph detector 1 during operation.

[0022] The pantograph detector 1 is provided with hollow rods 9 on the outer walls on both sides, and a telescopic rod 10 is inserted inside the hollow rod 9, a second spring 11 is provided inside the hollow rod 9, and the other end of the second spring 11 is connected to the inside of the telescopic rod 10, a rotating block 14 is inserted into the outer end of the telescopic rod 10, and the other end of the rotating block 14 is connected to a fixed frame 15, and second clamping rods 12 are respectively provided on the upper and lower outer walls of the fixed frame 15, and the second clamping rods 12 are respectively inserted in the fixed blocks on the hollow rod 9, and the second clamping rods 12 are respectively provided with elastic limit blocks 13 on the outside, and corresponding limit holes are opened on the fixed blocks, and the elastic limit blocks 13 are inserted in the limit holes.

[0023] Furthermore, the telescopic rod 10 forms an elastic telescopic structure with the hollow rod 9 through the second spring 11, and the fixed frame 15 forms an elastic locking limiting structure with the hollow rod 9 through the rotating block 14, the second locking rod 12, the elastic limiting block 13, thereby avoiding inconvenience in the movement process of the pantograph detector 1 through the retractable limiting component.

[0024] Furthermore, the fixing frame 15 forms a rotating structure with the telescopic rod 10 through the rotating block 14, thereby ensuring that the limiting assembly can perform limiting work normally at all positions of the pantograph.

[0025] A bidirectional screw 16 is inserted into the fixing frame 15, and a sliding rod 17 is correspondingly provided on one side of the bidirectional screw 16.

[0027] Working principle: When using the portable pantograph detection auxiliary device, the pantograph detector 1 can be moved by the roller 4 first, so that the pantograph detector 1 is moved to a suitable position of the pantograph for related work. When the pantograph detector 1 is moved, the pull plate 8 can be pulled upwards to disengage the first engaging rod 6 from the rotating rod 3, so that the roller 4 can be retracted into the groove 2 through the rotating rod 3, thereby preventing the roller 4 from affecting the stability of the pantograph detector 1 during operation; and the pantograph detector 1 can press the elastic limit block 13 during use, so that the limit plate 20 can be moved outward through the second spring 11 and the telescopic rod 10, and the limit assembly can be rotated to a suitable angle through the rotating block 14, thereby ensuring that the limit plate 20 can be at various positions of the pantograph. The pantograph detector 1 is limited in position, and then the bidirectional screw 16 can be rotated so that the pantograph detector 1 can be limited and placed near the pantograph through the limit plate 20 for detection; after the current position detection of the pantograph is completed, the pantograph detector 1 can be pulled upward, and the roller 4 rotates under the action of its own gravity, and the state of the roller 4 is limited by the first engaging rod 6, so that the pantograph detector 1 can be driven by the roller 4 to move around the pantograph; if the pantograph detector 1 is used up, the telescopic rod 10 is extended and retracted into the hollow rod 9 by the second spring 11, and the limit assembly is engaged and limited by the elastic limit block 13, so as to avoid the limit assembly from hindering the movement of the pantograph detector 1. This is the use process of the portable pantograph detection auxiliary device.
