During the manufacturing process of charging piles, the wiring harnesses used need to undergo various tests and can only be used after passing the tests.

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0016] The utility model provides Figure 1 to Figure 2 The charging pile wiring harness detection device for electric engineering vehicles shown in the figure comprises a detection platform 1. The detection platform 1 is arranged horizontally and a mounting seat 10 is welded and fixed on the top. Two dynamometers 11 are fixed on the top of the mounting seat 10 by bolts for displaying the tension.

[0017] Two limit slots 2 are cut on the test bench 1, and the two limit slots 2 are parallel to each other. A stretching block 6 is slidably assembled on the top of the test bench 1, and the stretching block 6 is in the shape of a letter π. The two bottom ends of the stretching block 6 correspond to the two limit slots 2 one by one, and each bottom end is limitedly slidably matched with the corresponding limit slot 2. The stretching block 6 slides along the two limit slots 2 to approach or move away from the mounting seat 10.

[0018] The testing platform 1 is equipped with a power mechanism, which is in transmission connection with the stretching block 6. The power mechanism includes a motor 5 and a screw 3. The motor 5 is bolted to the testing platform 1. The screw 3 is located in one of the limiting slide grooves 2 and is rotationally connected to the testing platform 1. The output shaft of the motor 5 rotates and penetrates into the testing platform 1, and is coaxially fixedly connected with the screw 3. The screw 3 passes through the bottom end of the stretching block 6 in the limiting slide groove 2 and is threadedly connected to the bottom end.

[0019] A guide rod 4 is placed horizontally in another limiting slide groove 2 of the detection platform 1, and the guide rod 4 is fixedly connected to the detection platform 1. The guide rod 4 passes through the bottom end of the stretching block 6 in the limiting slide groove 2, and the bottom end is limitedly slidably matched with the guide rod 4. It is ensured that the stretching block 6 does not rotate with the screw rod 3 during the sliding process.

[0020] Two charging pile harnesses for electric engineering vehicles are placed between the stretching block 6 and the mounting seat 10. The two charging pile harnesses correspond to two dynamometers 11 one by one, and each dynamometer 11 is fixedly connected to the terminal of the corresponding charging pile harness that needs to be tested.

[0021] Two support seats 8 are welded and fixed on the top of the stretching block 6. The two support seats 8 are composed of two support plates that are parallel and symmetrically arranged. A roller 9 is rotatably arranged between the two support plates of each support seat 8, and each roller 9 is rotatably connected to the support seat 8.

[0022] The two rollers 9 correspond to the two dynamometers 11 one by one, and the charging pile harness fixedly connected to each dynamometer 11 is wound on the corresponding roller 9, and the number of windings is one circle, which is used to pull the charging pile harness.

[0023] Two clamping holes are bored on the stretching block 6, and both clamping holes penetrate the stretching block 6 along the sliding direction of the stretching block 6. The two clamping holes correspond to the two rollers 9 one by one. After the charging pile harness to which each tensile gauge 11 is fixedly connected is wound around the corresponding roller 9 once, it passes through the clamping hole corresponding to the roller 9 in the direction close to the mounting seat 10. Figure 2 The curve with arrows.

[0024] An abutment block 7 is rotatably mounted in each clamping hole, and each abutment block 7 is rotatably connected to the stretching block 6 via a rotating shaft. A torsion spring is mounted between each abutment block 7 and the stretching block 6. Each torsion spring is sleeved on the rotating shaft connected to the abutment block 7, one end of each torsion spring is fixedly connected to the stretching block 6, and the other end of each torsion spring is fixedly connected to the abutment block 7 on the rotating shaft.

[0025] Each abutment block 7 is arranged obliquely and is inclined toward the direction close to the mounting seat 10. In the initial state, each abutment block 7 abuts against the bottom inner wall of the clamping hole.

[0026] Each abutment block 7 is frictionally coupled with the charging pile wiring harness in the clamping hole, and each abutment block 7 is clamped with the stretching block 6 to clamp and fix the charging pile wiring harness.

[0027] Working principle: When in use, fix one of the terminals of the charging pile harness for the electric engineering vehicle to be tested on the dynamometer 11. Then, wrap the end of the charging pile harness away from the dynamometer 11 around the corresponding roller 9. After wrapping around once, pass the end through the clamping hole corresponding to the roller 9 in the direction close to the mounting seat 10.

[0028] When the charging pile harness passes through the clamping hole, the charging pile harness pushes the abutment block 7 to rotate toward the mounting seat 10 through dynamic friction. After the charging pile harness passes through the clamping hole, the abutment block 7 slides and abuts against the charging pile harness. When the charging pile harness stops moving, the abutment block 7 abuts against the charging pile harness.

[0029] Then start the motor 5, and the output shaft of the motor 5 drives the screw 3 to rotate, and the screw 3 pushes the stretching block 6 to slide in the direction away from the mounting seat 10. The roller 9 pulls the charging pile harness until the charging pile harness is straightened. During this process, the roller 9 rotates. At the same time, the charging pile harness pushes the abutment block 7 to rotate in the direction away from the mounting seat 10 under the action of friction. Due to the existence of the charging pile harness, the abutment block 7 cannot abut against the bottom inner wall of the clamping hole, so the abutment block 7 and the stretching block 6 clamp and fix the charging pile harness together.

[0030] As the stretching block 6 continues to slide away from the mounting seat 10, the charging pile harness is wound around the roller 9, and the roller 9 pulls the charging pile harness. In this process, the clamping force of the abutment block 7 and the stretching block 6 on the charging pile harness continues to increase, thereby clamping the charging pile harness so that the charging pile harness will not detach from the stretching block 6.

[0031] After the detection is completed, it is only necessary to push the abutment block 7 toward the mounting seat 10 so that the abutment block 7 is rotated and separated from the charging pile harness.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
