[0023] The power cord is fixed to the cylinder 2 through the fixing assembly 4, passes through the through hole 10 on the frame 1 and is connected to the counterweight assembly 3. Then, the lifting of the counterweight assembly 3 by the power cord is realized by the rising of the cylinder 2, thus realizing the automated operation of the power cord tensile test, improving the detection efficiency, and simplifying the test process of the power cord. This not only reduces the working intensity of the operators, but also greatly improves the detection quality of the power cord. It can be operated and detected without professional detection personnel. Secondly, the setting of the time relay 5 can perform delay control on the cylinder 2. The reset of the cylinder 2 can be controlled by setting the time of the time relay 5, that is, the time of the power cord tensile test can be set by setting the delay time of the time relay 5, so that the entire hanging scale testing machine can meet the test requirements of different power cords and improve the practical performance.

[0024] The fixing component 4 includes a fixing plate 41 and a fixing sleeve 42. The fixing plate 41 is arranged on the cylinder 2, and the fixing sleeve 42 is arranged on the fixing plate 41. A fixing hole 43 is provided on the fixing plate 41. By setting the fixing component 4 as the structure of the fixing plate 41 and the fixing sleeve 42, the fixing plate 41 can increase the contact area between the entire fixing component 4 and the cylinder 2, ensuring the stability of the fixing component 4 during up and down movement. The fixing sleeve 42 can simplify the fixing structure of the power cord, facilitating the placement and retrieval of the power cord. Specifically, an opening 44 is provided on the fixing sleeve 42 to reduce the sway of the power cord. A guiding mechanism 6 is provided between the fixing plate 41 and the frame 1. The guiding mechanism 6 includes a guiding rod 61 and a guiding sleeve 60. The guiding rod 61 is arranged inside the guiding sleeve 60. By setting the guiding mechanism 6 between the fixing plate 41 and the frame 1 and configuring the guiding mechanism 6 as the structure of the guiding sleeve 60 and the guiding rod 61, the straightness of the fixing plate 41 during up and down movement can be ensured, avoiding the sway of the counterweight component 3 during the testing process and improving the safety performance of the testing. Specifically, the guiding sleeve 60 is arranged on the frame 1, the guiding rod 61 is arranged on the fixing plate 41, and a limiting block 62 is provided on the guiding rod 61.

Setting the frame 1 into the structure of the bottom plate 11, the top plate 12 and the columns 13 can simplify the installation structure of the entire frame 1 and facilitate the installation of the air cylinder 2 and the counterweight assembly 3. Specifically, the air cylinder 2 is installed on the top plate 12, and the counterweight assembly 3 is placed on the bottom plate 11. The setting of the buffer pad 15 can slow down the impact force of the counterweight assembly 3 on the bottom plate 11 when the counterweight assembly 3 descends, thereby increasing the service life of the entire frame 1. The setting of the moving wheel 14 facilitates the movement of the entire frame 1 and is convenient for testing. A start switch 7 connected to the time relay 5 is provided on the frame 1. The setting of the start switch can control the action of the air cylinder 2 and is convenient for the operator to operate. An indicator light 8 connected to the start switch 7 is provided on the frame 1. The setting of the indicator light can play a certain indicating function during the testing process.
