Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not paying creative work premise, broadly fall into the scope of this utility model protection.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of TBM hob self-locking connecting bolt, including connecting bolt 3, connecting bolt 3 is provided with the first nut 1, and the first nut 1 outer end is provided with sleeve 2, and left-hand bolt 5 is connected through sleeve 2 with connecting bolt 3 lower end. Connecting bolt 3 top is provided with nut 3-1, and nut 3-1 is arranged on hob holder. Connecting bolt 3 lower outer is provided with right-handed thread, right-handed thread and the first nut 1 and matches, and connecting bolt 3 is connected by right-handed thread and the first nut 1. Being provided with the first screw 3-2 in connecting bolt 3 bottom, set left hand thread in the first screw 3-2, left hand thread and left-hand bolt 5 match, and connecting bolt 3 is connected with left-hand bolt 5 by left hand thread. Connecting bolt 3 lower end is plane, is conveniently connected with sleeve 2 inside.
Connecting bolt 3 is provided with the second nut 6, and the second nut 6 is positioned at the upper end of the first nut 1. First nut 1 and arranging of the second nut 6 can realize preventing coming off of heart-shaped fixture block 7. First nut 1 and the second nut 6 are outer-hexagonal nut, and sleeve 2 is the interior hexagonal sleeve 2 matched with the first nut 1. Namely sleeve 2 top is provided with hollow interior hexagonal, and size and the first nut 1 match, and facilitate the first nut to be disposed therein. Sleeve 2 bottom is provided with the second screw 2-1, and the second screw 2-1 is provided with left hand thread, and sleeve 2 is connected with left-hand bolt 5 by left hand thread. Left-hand bolt 5 is M16 left-hand bolt.
