Abstract

The utility model relates to an automatic coupling device for mine cars, composed of a fixed ring, a split ring, and an operating mechanism. The utility model is characterized in that the split ring parallels with ground, and is installed side by side and vertically with the fixed ring; one end of a movable half ring is half ring form, and the other end is a fan-shaped body; when the movable half ring is closed into circular ring, holes of the fan-shaped body are engaged with holes of a base; connector pin is automatically inserted and completes the hook action, forming a double hook connection; the operating mechanism is utilized to unhook, causing the connector pin to exit, and the utility model completes to unhook. The utility model has the advantages of simple structure, convenient operation, high safety, and high efficiency. The utility model is suitable for connection and separation between other similar types vehicles.

Description

The mine car auto-coupling

The utility model relates to a kind of mine car auto-coupling, belongs to automobile-used annex.

Current in the middle-size and small-size mining firm of each mining industry, the ore of underground mining, have and utilize inclined shaft to transport mine to ground a certain specified point by the mine car of electrically propelled traction vehicle traction by steel cable, gallery (road), and the connection of mine car is normally with iron chains or iron hoop, fix with pin, all be artificial the connection and excision, time-consuming, the effort of this method, conveying efficiency is low.

It is a kind of simple in structure that the purpose of this utility model is to provide, and processing ease is safe and reliable, the mine car auto-coupling that conveying efficiency is high.

Realize that structure of the present utility model comprises set collar, slotted ring, steering unit, its principal character is that the orthogonal layout of set collar and slotted ring is installed side by side, and slotted ring is parallel to the ground, being stretched in the slotted ring of second car by the set collar of first car during hook makes the quadrntnt of the movable semi-ring in the slotted ring toward retraction, then the other end and stationary half are closed into circle, hole on the movable semi-ring quadrntnt overlaps with the hole of seat at the end at this moment, pin inserts in the hole under the effect of spring movable semi-ring is fixed, finish the hook action, steering unit is to be provided with for breaking off relations.

Below will be further elaborated by embodiment of the present utility model and accompanying drawing thereof.

Accompanying drawing 1 is the auto-coupling structural representation;

Accompanying drawing 2 is that auto-coupling A is to view;

Accompanying drawing 3 is an auto-coupling pin structural representation.

The drawing reference numeral explanation:

1, bolt 2, spring 3, handle 4, connecting rod

5, push rod 6, cam 7, joystick 8, support

9, cross wheel 10, movable semi-ring 11, pin 12, base

13, rubber block 14, axle 15, annulus

Referring to Fig. 1,2, present embodiment comprises set collar, slotted ring, steering unit.Set collar comprises the annulus 15 and the spring 2 of band handle 3, is installed on the base 12, and spring mainly has been a buffer action, reduces impulsive force, should install vertical with slotted ring and side by side when set collar is installed, and guarantee that this ring can not rotate; Slotted ring comprises base 12, axle 14, movable semi-ring 10, pin 11, have one to constitute the stationary half of a domain on the base 12 with an end of movable semi-ring, its end has an axis hole to cooperate movable semi-ring hinged with axle 14, and there is a spring to make the always open-shaped attitude of movable semi-ring, movable semi-ring 10 is members of a horse-hof shape, one end is to constitute the semi-circular of annulus with stationary half, one end is the fan-shaped body, there is axis hole the centre, be installed in base 12 middle installations parallel to the ground, the fan-shaped body has a hole, this hole is when movable semi-ring and stationary half are closed into annulus, overlap with the hole on the base 12, this moment, pin 11 in the inserting hole, fixed movable semi-ring under spring 17 and effect connecting rod 4, formed a domain, thereby finish the hook action, the fan-shaped body of movable semi-ring 10 should stretch in the stationary half when opening, past rollback when closed; Operating mechanism referring to Fig. 3, comprises support 8, cross wheel 9, cam 6, spring 16,17, connecting rod 4, push rod 5, joystick 7, joystick 7 is installed on the support 8, one end of dress cross wheel 9 stretches out outside the car body, and an end is equipped with an oval-shaped cam 6, and it is pressed on the push rod 5, push rod 5 is pressed on the connecting rod 4, one end of connecting rod 4 is hinged on the base 12, and an end and pin 11 connect together, and has spring 17 to hold connecting rod on the base, there is spring 16 to withstand on the push rod 5, makes them remain state upwards.For the collision that prevents mine car causes damage, the rubber block 13 of buffer action also has been installed, for ease of installing, there is bolt 1 to be connected with the mine car vehicle frame.

The condition of service of present embodiment is: when two cars will be linked up with, its initial condition should be that movable semi-ring is open, oval-shaped cam on the joystick, minor axis contacts with push rod 5, spring 16 ejects the disengaging connecting rod with push rod 5, the spring 17 of base upwards draws connecting rod like this, makes pin that one power that makes progress be arranged.When therefore two cars are collided, stretch in the open slotted ring perpendicular to ground-surface set collar, and the fan-shaped body of collision activity semi-ring and when shifting the other end of movable semi-ring always inwards onto and contacting the formation annulus with stationary half on the base, the circular hole on the movable semi-ring overlaps with circular hole on the base 12.Owing to the effect of spring 17 can not be opened the action of finishing hook with being fixed into annulus in the pin patchhole, when breaking off relations as needs, then pull the cross wheel, make the joystick half-twist, promptly allow the longitudinal end of oval cam contact with push rod, push rod is moved down press to connecting rod, connecting rod to move down pin then and withdraw from the hole of base and movable semi-ring and decoupling device.So just can finish the action of automatic hitch and decoupling device, make the method for cross wheel half-twist can manually also can need the place of decoupling device to bury a device underground on the ground and make cross take turns half-twist.

The utility model is simple in structure as from the foregoing, and is easy to operate, and the hook back forms double hook and connects, and is safe and reliable, the conveying efficiency height, and it is not only applicable to mine car, equally is applicable to the connection between other same type vehicles yet.
