[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This specific embodiment is a mechanical fault auxiliary analysis device, the structural schematic diagram of which is shown below. Figures 1 to 3As shown, the fault analyzer includes a main housing 1, with a cover 2 installed on the upper end of the main housing 1. An auxiliary mechanism is provided at the lower end of the main housing 1, and the auxiliary mechanism includes a connecting frame 301 fixedly connected to the four corners of the lower side of the main housing 1. A round shaft 302 is fixedly connected to the inner side of the connecting frame 301. A threaded rod 303 is connected to the front end of the connecting frame 301. A first handle 304 is welded to the front side of the threaded rod 303. A rotating rod 305 is connected to the inner side of the connecting frame 301. An adjusting rod 306 is connected inside the rotating rod 305. A roller 307 is installed at the end of the adjusting rod 306 away from the rotating rod 305. A rotating hole is opened at the end of the rotating rod 305 away from the roller 307. The front and rear sides of the end of the rotating rod 305 away from the roller 307 are slidably connected to the inner side of the connecting frame 301. The outer side of the round shaft 302 is rotatably connected to the inner side of the rotating hole. A pull rod 308 is installed at the bottom of the main housing 1 of the fault analyzer. Limiting blocks 309 are fixedly connected to the front and rear sides of the left end of the pull rod 308. A threaded groove is opened at the front end of the rotating rod 305 near the rotating hole. Circular holes are opened at the left, right and bottom of the front end of the connecting frame 301. The outer side of the threaded rod 303 is slidably connected to the inner side of the circular hole, and the outer side of the rear end of the threaded rod 303 is threadedly connected to the inner side of the threaded groove. Thus, when the rotating rod 305 is rotated to the left, right or vertically downward around the circular shaft 302, the rotating rod 305 can be fixed to the inner side of the connecting frame 301 by threading the threaded rod 303 through the circular hole and connecting it to the threaded groove.

[0026] The fault analyzer main housing 1 has a U-shaped groove on the lower right side inside. Sliding grooves are located at the front and rear ends of the U-shaped groove inside the main housing 1. The outer side of the pull rod 308 is slidably connected to the inner side of the U-shaped groove, and the outer side of the limiting block 309 is slidably connected to the inner side of the sliding groove. By adjusting the rotating rod 305 at the lower left end of the fault analyzer main housing 1 to a horizontal position to the left, and then pulling the pull rod 308 out of the main housing 1, the main housing 1 can be placed upright on the ground via the roller 307 at the lower left end. Pulling the pull rod 308 allows the entire main housing 1 to be moved, making it more convenient to carry during field operations.

[0027] Cooperate Figure 4As shown, the adjusting rod 306 has fixing units at both its inner and outer ends. Each fixing unit includes a fixing plate 401 fixedly connected to the outer end of the adjusting rod 306 away from the rotating rod 305. Insert rods 402 are connected to the front and rear ends inside the fixing plate 401. A second handle 403 is welded to the end of the insert rod 402 near the connecting frame 301. Threaded holes are provided at the front and rear ends inside the fixing plate 401. External threads are provided on the outer side of the insert rod 402, which is threaded to the inner side of the threaded hole. The end of the insert rod 402 away from the second handle 403 is a pointed end. Thus, when the rotating rod 305 is adjusted to a vertically downward position, the rollers 307 at the four corners of the lower end of the fault analyzer main housing 1 are used to support it on the ground. Then, rotating the second handle 403 causes the insert rod 402 to rotate within the threaded hole and move downwards until the lower end of the insert rod 402 is inserted into the ground, allowing the fault analyzer main housing 1 to be erected on the ground in the field.

[0028] The adjusting rod 306 has a spring 404 internally connected to it, and one end of the spring 404 is fixedly connected to a sliding rod 405. A rectangular groove is formed at the end of the rotating rod 305 away from the connecting frame 301, and a circular groove is formed at the end of the adjusting rod 306 near the connecting frame 301. The end of the spring 404 away from the sliding rod 405 is fixedly connected to the innermost end of the circular groove. Insertion holes are formed at equal intervals on the upper part of the rotating rod 305 within the rectangular groove. The outer side of the sliding rod 405 is slidably connected to the inner side of the circular groove and the insertion holes. The outer side of the adjusting rod 306 is slidably connected to the inner side of the rectangular groove. By sliding the adjusting rod 306 along the inner side of the rectangular groove inside the rotating rod 305, and then pushing the sliding rod 405 upward by the spring 404, the sliding rod 405 moves upward into the corresponding insertion hole, so that the rotating rod 305 and the adjusting rod 306 are fixed relative to each other again. This allows the overall length of the rotating rod 305 and the adjusting rod 306 to be adjusted, so that the main body 1 of the fault analyzer can be supported and fixed at different heights to accommodate the operation and use of personnel at different heights.

[0029] Working principle: When this mechanical fault analysis auxiliary device is carried to the field, the rotating rod 305 at the lower left end of the fault analyzer main body 1 is rotated to the horizontal left. Then, the threaded rod 303 is passed through the round hole at the lower left end of the connecting frame 301 and then threaded into the threaded groove. After fixing the rotating rod 305, the pull rod 308 at the lower inside of the fault analyzer main body 1 is pulled out. Then, the fault analyzer main body 1 is stood up so that the roller 307 at the lower left end of the fault analyzer main body 1 is on the ground. Then, the pull rod 308 is pulled to make the fault analyzer main body 1 move smoothly and effortlessly in the field.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
