Abstract
The utility model discloses a device is escaped to round pin axle anticreep, including first cutting ferrule (1), second cutting ferrule (3), tie (2), dop (5), apron (6) and rubber nylon spring (4), the one side of tieing (2) is close to end department and sets up slottedly, groove from interior to exterior sets gradually rubber nylon spring (4), dop (5), rubber nylon spring (4), dop (5) are sealed through apron (6), division there is the bayonet socket the corresponding position in second cutting ferrule (3) and dop (5). Compact structure, the operation of being convenient for reduce workman intensity of labour, improvement work efficiency, and the practical anticreep of selling the axle under various different work condition is prevented escaping, and it is extremely convenient to dismantle and install, safe and reliable.
Description
Technical field
The utility model relates to a kind of anti-escaping device, is specifically related to the anti-escaping device of a kind of bearing pin.
Background technique
Pinned connection is Placement common in engineering machinery, its means of fixation has multiple, because operating mode is different, the bearing pin of static connection does not have problems substantially, be dynamically connected due to unbalance stress, load frequent impact, especially coal mine equipment are all generally that load ratio is larger, and work under bad environment, operating mode is unstable, easily makes bearing pin generation axial float, even if having nut or clamp, once bearing pin rotates, occur axial float phenomenon unavoidably, under this special operation condition, there is very large hidden danger in the Safety performance of equipment.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of bearing pin anti-escaping device, can limit the movement of bearing pin class link easily, easily, and energy self-locking, unless manual operation, otherwise device can not self falling.
To achieve these goals, the technical solution adopted in the utility model is: the anti-escaping device of a kind of bearing pin, comprise the first cutting ferrule, the second cutting ferrule, bolt, dop, cover plate and rubber nylon spring, the side of bolt offers groove near end place, groove sets gradually rubber nylon spring, dop from the inside to the outside, rubber nylon spring, dop are by cover plate for sealing, and the second cutting ferrule position corresponding with dop has bayonet socket.
Further, dop dual-side is provided with chamfering.
The beneficial effects of the utility model are: compact structure, convenient operation, reduce labor strength, increase work efficiency, and the anticreep being practically applicable to various different operating mode lower bearing pin is prevented escaping, and it is extremely convenient, safe and reliable to dismantle and install.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view after the utility model dop is connected with the second cutting ferrule;
In figure: 1, the first cutting ferrule, 2, bolt, the 3, second cutting ferrule, 4, rubber nylon spring, 5, dop, 6, cover plate.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, the anti-escaping device of this bearing pin, comprise the first cutting ferrule 1, second cutting ferrule 3, bolt 2, dop 5, cover plate 6 and rubber nylon spring 4, the side of bolt 2 offers groove near end place, groove sets gradually rubber nylon spring 4, dop 5 from the inside to the outside, rubber nylon spring 4, dop 5 are sealed by cover plate 6, and the second cutting ferrule 3 position corresponding with dop 5 has bayonet socket; Dop 5 dual-side is provided with chamfering, facilitates the movement of bolt 2, reduces resistance.
First cutting ferrule 1, second cutting ferrule 3 is set in advance in the workpiece body of bearing pin both sides, during work, bolt 2 and entirety thereof insert the first cutting ferrule 1 left successively from right side, in second cutting ferrule 3, when dop 5 touches the second cutting ferrule 3 edge, pin dop 5 with hand inwardly to push away, when dop 5 chamfering enters into the second cutting ferrule 3 inside, strengthen power from right to left, it is inner that whole bolt 2 just slides into the second cutting ferrule 3, when moving to the bayonet socket place of the second cutting ferrule 3, rely on the elastic-restoring force of rubber nylon spring 4, dop 5 can eject from bayonet socket, bolt 2 cannot continue to move left and right, realize locking, releasing process: press dop 5 equally, makes chamfer contact to the second cutting ferrule 3 edge, and strengthen power from left to right, dop 5 is reduced in cavity voluntarily, and package unit just takes out.
Claims (2)
1. the anti-escaping device of bearing pin, it is characterized in that, comprise the first cutting ferrule (1), the second cutting ferrule (3), bolt (2), dop (5), cover plate (6) and rubber nylon spring (4), the side of bolt (2) offers groove near end place, groove sets gradually rubber nylon spring (4), dop (5) from the inside to the outside, rubber nylon spring (4), dop (5) are by cover plate (6) sealing, and the second cutting ferrule (3) position corresponding with dop (5) has bayonet socket.
2. the anti-escaping device of a kind of bearing pin according to claim 1, is characterized in that, described dop (5) dual-side is provided with chamfering.
