Abstract
The utility model relates to a pin-disconnection preventing device of a mine car, which is arranged on components which are used for mutually hanging and connecting with the mine cars. The utility model comprises two large parts which comprise a main pin and a main pin sleeve. The utility model is characterized in that the pin-disconnection preventing device is provided with the cylindrical main pin, a step-shaped main lock sleeve with a center hole forms a slipping fit with the main pin, a lock pin is transversally installed on the upper part of the main pin, the upper part of the main lock sleeve is provided with a vertical lock groove structure towards the vertical direction and a horizontal lock groove structure towards the horizontal direction. Hands carry the handle of the main pin when the utility model is used, the lock pin is leaded into the vertical lock groove and the horizontal lock groove, and thus, a locked part can be firmly locked by the main pin. The pin-disconnection preventing device of a mine car has the advantages of simple structure, little material use, strong tarnishing and impacting resistance, high mechanical strength, safety, and convenient use and operation, can thoroughly eliminate the hidden dangers and accidents, such as pin position changing, hook sliding down and car running, and has the practical value of popularization.
Description
Technical field
The utility model relates to the mine car locking pin device on the mutual hanging member of colliery mine car.
Background technology
At present, during the gradient tunnel transportation, the connection between the mine car, the connection between mine car and the steel rope, still exist accident potential and accidents such as scurrying pin, unhook, sport car, and preceding some band steel locking locking pin devices, open type lock tube locking pin device and close latch sleeve anti-drop pin assembly, all exist unreasonable structure, fragile distortion, corrosion is fast, operating cycles is short, and the shortcoming of not easy to plug and poor reliability does not also have good terms of settlement at present.
Empty in the invention
In order to overcome the more existing shortcomings of present mine car bolt device, the utility model provides a kind of mine car locking pin device, this apparatus structure is simple, materials are few, corrosion resistant and colliding, the mechanical strength height, safe and reliable, use easy to operately, can thoroughly eliminate the hidden danger and the accident of scurrying pin, unhook and sport car.
The scheme that its technical matters that solves the utility model adopts is: this device comprises stub (5) and stub cover (4) two large divisions; It is characterized in that: this device has a columniform stub (5), with the stub cover (4) that a step has centre hole that is equipped with of stub (5) sliding fit; The upper lateral of stub (5) is equipped with a locked pin (2), stub cover (4) top, have vertically to vertical locked cotter way (7) and level to the locked cotter way of level (3) structure.During use, the handgrip (1) of portable stub (5) imports locked pin (2) in vertical locked groove (7) and the locked cotter way of level (3), can make stub (5) the firm pinning of latch fitting (6).
Its beneficial effect is: owing to adopted such scheme can make this mine car locking pin apparatus structure simple, materials are few, corrosion resistant and colliding, the mechanical strength height, safe and reliable, use easy to operately, can thoroughly eliminate the practical value that the hidden danger of scurrying pin, unhook and sport car and accident have penetration and promotion.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is a structural principle scheme drawing of the present utility model.
Accompanying drawing 2 is the plan structure principle intention of the utility model stub cover utmost point stub.
Among the figure: 1, handgrip, 2, locked pin, 3, the locked cotter way of level, 4, the stub cover, 5, stub, 6, latch fitting, 7, vertical locked cotter way.
The specific embodiment
In the drawings, stub (5) is the long cylinder shape that a round steel is made, its upper end has the handgrip (1) of closed shape, side direction on handgrip lower cylindrical top, the horizontal locked pin (2) that is equipped with, the diameter of this locked pin can make locked pin import and export easily less than the width and the height of vertical, the locked cotter way of level (7), (3).Elder generation vertically falls into vertical locked cotter way (7) during importing, revolves then to turn 90 degrees, and can import in the locked cotter way of level (3) to fixedly secure.
In the drawings, stub cover (4) is the circle cover of a step, there is a round tube hole at its center, this bore dia is greater than the external diameter of stub (5), and the insertion that stub (5) is slided is extracted, on the round platform on stub cover (4) top, the vertical vertically-guided groove (7) that has, its degree of depth is concordant with second step of stub cover, and then, a left side or right level are again opened out the locked cotter way of level (3); This is vertical, the width of horizontal locked groove and height, all greater than the diameter of locked pin (2), so that make locked pin can derive importing easily.
Claims (3)
1, a kind of mine car locking pin device, this device comprise stub (5) and stub cover (4) two large divisions; It is characterized in that: this device has a columniform stub (5), with the stub cover (4) that a step has centre hole that is equipped with of stub (5) sliding fit; The upper lateral of stub (5) is equipped with a locked pin (2), stub cover (4) top, have vertically to vertical locked cotter way (7) and level to the locked cotter way of level (3) structure.
2, a kind of mine car locking pin device according to claim 1, it is characterized in that: stub (5) is the long cylinder shape that a round steel is made, and its upper end has the handgrip (1) of enclosed shape: the diameter of this locked pin (2) of its top is less than the width and the height of vertical, the locked cotter way of level (7), (3).
3, a kind of mine car locking pin device according to claim 1 is characterized in that: stub cover (4) is the circle cover of a step, and its center is a round tube hole, and this round tube hole is greater than the external diameter of stub cover (4); Second step of the degree of depth of vertically-guided groove (7) and stub cover is concordant, and this is vertical, the width of horizontal locked groove and height, all greater than the diameter of locked pin (2).
