DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0017] As Figures 1 to 4As shown, the utility model discloses a harvester steering bridge flip assembly tool, including a hanging plate 1, a sleeve 2 and an anti-slip sleeve 3. A hanging hole 5 is provided at one end of the hanging plate 1, and a mounting hole is provided at the other end. The sleeve 2 is installed in the mounting hole. A stop is provided on the outside of the sleeve 2 for limiting the depth of the sleeve 2 installed in the mounting hole. The sleeve 2 is provided with an internal threaded hole 2.1, a through hole 2.2 and a through hole 2.3 that are connected in sequence. The through hole 2.3 is located near one end of the hanging plate 1. The inner diameter of the through hole 2.2 is larger than the inner diameter of the internal threaded hole 2.1. One end of the anti-slip sleeve 3 is provided with a boss 3.1, and the boss 3.1 is provided with an external thread. The external thread and the internal thread hole One is adapted to the through hole 2.1, and the boss 3.1 is rotatably arranged in the through hole 2.2. Since the inner diameter of the through hole 2.2 is larger than the inner diameter of the internal threaded hole 2.1, after the boss 3.1 passes through the internal threaded hole 2.1, the anti-loosening sleeve 3 can rotate 360° in the through hole 2.2. Furthermore, the inner diameter of the through hole 2.3 is smaller than the inner diameter of the through hole 2.2, thereby limiting the boss 3.1 to prevent it from falling out. An internal threaded hole 2 is provided on the anti-loosening sleeve 3, and the internal threaded hole 2 is used to connect with the connecting bolt 7 on the steering axle 6. The thread rotation direction of the internal threaded hole 2 is opposite to the thread rotation direction of the external thread on the boss 3.1, which plays a role in preventing it from being unhooked.

[0018] In this embodiment, the anti-dropout sleeve 3 is provided with a symmetrically arranged clamping surface 3.2, which is located at the end away from the boss 3.1. This allows tools such as a wrench to be easily engaged with the clamping surface 3.2, thereby facilitating the connection between the anti-dropout sleeve 3 and the bolts on the steering axle 6 and improving operational convenience.

[0019] The clamping surfaces 3.2 can be provided in one pair or multiple pairs to improve the convenience of clamping.

[0020] The harvester steering axle flip assembly tool also includes a hexagonal bolt 4, which is fixedly connected to the anti-slip sleeve 3. In this embodiment, the second internal threaded hole penetrates the anti-slip sleeve 3, and the hexagonal bolt 4 is installed in the second internal threaded hole at one end. The hexagonal bolt 4 is then welded to the anti-slip sleeve 3 or fixed together with thread glue. By fixing the hexagonal bolt 4 to one end of the anti-slip sleeve 3, the operator can rotate the anti-slip sleeve 3 by turning the hexagonal bolt 4, thereby connecting the anti-slip sleeve 3 to the connecting bolt 7, improving the convenience and work efficiency of operation, and the structure is simple.

[0021] In this embodiment, the external thread on the boss 3.1 is right-handed, while the thread of the second internal threaded hole is left-handed. Since the external thread of the boss 3.1 and the thread of the second internal threaded hole are in opposite directions, when the anti-dropout sleeve 3 is connected to the connecting bolt 7 on the steering axle 6, the anti-dropout sleeve 3 is unlikely to fall out of the sleeve 2, thus preventing it from being unhooked and further improving safety.

[0022] Optionally, the helix direction of the external thread on the boss 3.1 is left-handed, and the helix direction of the internal thread in the second internal thread hole is right-handed, which can also achieve the function of preventing the hook from disengaging.

[0023] The using process of the utility model is as follows:

[0024] A plurality of connecting bolts 7 are provided at both ends of the steering axle 6. The connecting bolts 7 on the lower sides of both ends of the steering axle 6 respectively pass through the through holes 2.3 of the sleeve 2 and are connected to the second internal thread holes of the anti-disengagement sleeve 3. Since the helix directions of the external thread and the internal thread in the second internal thread hole of the anti-disengagement sleeve 3 are opposite, it plays a role in preventing the hook from disengaging. The crane hoists the steering axle 6 from both ends through the hoisting holes 5. Due to the action of gravity, the steering axle 6 flips. After the steering axle 6 flips, it is docked with the chassis. Since the anti-disengagement sleeve 3 can rotate 360° within the sleeve 2, when the steering axle 6 flips, the hanging plate 1 always remains in a vertical state, thus avoiding the situation that the hanging plate 1 disengages from the hook, ensuring the safety when the steering axle 6 flips, and reducing the labor intensity of the operator.

[0025] The above are only the preferred embodiments of the utility model, and are not intended to limit the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included within the protection scope of the utility model.
