Abstract

The utility model relates to an automatic locking structure for rail vehicles, which is a tractive connection component among the rail vehicles. A pin joint mode is adopted, and the pin joint can be automatically realized through a set of linkage mechanisms. In the linkage mechanisms, the dynamic force of relative motion of a connecting piece is transferred to a constraint piece by a touching piece through a component which only transfers unidirectional dynamic force to cause the constraint piece to be separated from the position of a constraint pin, and the pin is automatically inserted into a pin hole under the action of gravity or elasticity. A funnel-shaped joint and a convex joint which is matched with the funnel-shaped joint are adopted by the connecting piece to cause the para position to be accurate, and partial oversize impact force can be prevented. The utility model is suitable for automatic locking of the rail vehicles in mining areas and forest areas at any time at all locations.

Description

Automatic locking unit for rail vehicle

The automatic hanging structure of railroad vehicle is to draw link between the railroad vehicle, and type of attachment is the pin joint that is formed by pin and attaching parts, and the latch in the pin joint process is finished from moving by a cover interlinked mechanism.

Traction between the railroad vehicle connects, and adopts articulating of pin, bolt, chain more, though simple in structure, all be artificial connection, link ratio difficulty on sloping road especially.Some automatic engagements, as the automatic engagement structure of train etc., the rail that requires to carry out the automatic engagement place must be straight.In the mining area, the forest zone, connect anywhere or anytime between the railroad vehicle, these automatic engagement structures are not convenient usefulness.

This automatic hanging structure adopts the latch type of attachment of pin, this structure design is exactly in articulating process, the practice pin inserts the pin-and-hole of attaching parts automatically, form and articulate automatically, adapting to mining area and forest zone railroad vehicle articulates on curved rail and acclive track automatically, and claimed structure is fairly simple, and is easy to use.

This automatic hanging structure is to realize articulating automatically by the power of vehicle relative motion, it contains main attaching parts (1), Connector Clip (23), pin (16), main attaching parts, Connector Clip have pin-and-hole, insertion by pin forms pin joint, when the other end of main attaching parts, Connector Clip is respectively to connect with vehicle separately, even articulate between the vehicle.From moving practice, this cover interlinked mechanism is loaded on main attaching parts, generally is contained in above the main attaching parts by a cover interlinked mechanism in the insertion of pin.Mainly touch part (6) and attaching means (8) in the interlinked mechanism, touch part, attaching means are equipped with axle (3,11) respectively, touch part and attaching means all rotate around the axle of self in the interlock process, in order to limit the slewing area of touch part, attaching means, locating dowel pin (4,10) can be housed, also can utilize the housing of interlinked mechanism or the planform of main attaching parts to come spacing.Attaching means mainly is to be used for the constraint pin, and when not carrying out pin joint, pin is lived in the constraint of an end of attaching means, makes pin not enter pin-and-hole.Touch part mainly is that transferring power is given attaching means, produces interlock, makes attaching means leave the position of constraint pin, makes pin insert pin-and-hole down at gravity or elastic force (being connected with spring with pin, as the pressure spring of suit) effect.And touch part drives by relative motion in main attaching parts and the Connector Clip docking operation, is just touched by Connector Clip.For this reason, when main attaching parts and Connector Clip released state, the position a when end of touch part is positioned at Connector Clip pin end pin joint, so that when main attaching parts and Connector Clip contraposition pin joint, Connector Clip touches touch part.Return behind touch part, the attaching means interlock is just got back to the preceding position of interlock, reliable self gravitation or elastic force.As utilize elastic force, attaching means or touch part or both that spring (5,12) will be housed.For main attaching parts, Connector Clip by the pin joint process in touch part, attaching means interlock, and in main attaching parts, Connector Clip separation process, touch part return, touch part, attaching means not interlock or not restrained of touch part block can not return.Add the parts (7) that only transmit unidirectional power between touch part and attaching means, parts are connected with attaching means or touch part.These parts can be the wheel or the pieces of a unidirectional rotation, as the turning block of gear, ratchet, regular shape.Wheel or piece can be connected with attaching means or touch part by axle, like this when touch part is touched by Connector Clip, it is that it is not rotated that the wheel of unidirectional rotation or piece are subjected to force direction, then drive the attaching means interlock, and when the touch part return, it is that it is rotated that the wheel of unidirectional rotation or piece are subjected to force direction, then because its rotation and do not drive the attaching means interlock.These parts also can be the swing components that can only swing in certain angular range, and swing component is connected with attaching means or touch part hinge, and are added with the spring that swing component is produced circumferential elastic force, and the elastic force direction is to make swing component be in one side of pendulum angle scope.Like this, when touch part was touched, it was beyond the pendulum angle scope that swing component is subjected to force direction, swing component does not rotate, and promptly drives the attaching means interlock, and when the touch part return, it is in the pendulum angle scope that swing component is subjected to force direction, and then swing component swing does not drive the attaching means interlock.

The parts that only transmit unidirectional power can also be sliding part (7).Attaching means or touch part have chute, and chute is equipped with sliding part, and sliding part can be equipped with the elastic force direction and be roughly groove spring (9) longitudinally.Like this,, in the Connector Clip pin joint process, the power of touch part is passed to attaching means, produce interlock, attaching means is removed from the position of constraint pin by sliding part at main attaching parts.In the interlock process, touch part, attaching means are with separately axle turn, and sliding part is also with wherein one (attaching means or touch part) turn.After the later stage of interlock is screwed into certain position separately, sliding part just breaks away from another part (touch part or attaching means), attaching means no longer is subjected to the effect of touch part by sliding part, attaching means is got back to the position of former constraint pin under gravity or elastic force effect, prepares against promptly to be constrained after pin is transferred to pin-and-hole.After pin was transferred to pin-and-hole and restrained constraint to live, when main attaching parts, when Connector Clip separates, touch part no longer was subjected to the effect of Connector Clip and return.Limited because of attaching means during return, the motion of touch part only drives sliding part and slides in chute, and sliding part is transferring power not.To opposite side, sliding part is got back to the position before sliding again to sliding part under gravity or elastic force effect from a side relative motion of touch part or attaching means.

Main attaching parts, Connector Clip articulate automatically, need both contrapositions accurately, so that pin inserts both pin-and-holes, it is excessive to wish not produce local impulse force simultaneously.So generally speaking, the pin joint end of main attaching parts is infundibulate, and the pin joint end of Connector Clip can be convex, and roughly matches with the inner chamber of main attaching parts funnel pin joint end.The other end of Connector Clip is fork-shaped, can directly be connected with vehicle, also can be connected with commutation joint (2) hinge, and adapter shaft (22) is vertical with pin (16).Hold-down plate spring is equipped with in the commutation joint side parallel with adapter shaft.

Such automatic hanging structure has been realized the automatic pinning of pin joint process, makes interlinked mechanism that pin inserts pin-and-hole automatically mainly by touch part, and attaching means, the parts that only transmit unidirectional power are formed, and are relatively simple for structure.The structure design of attaching parts makes on detour and rugged sloping road also aligned position pin joint successfully, and has avoided local impulse force excessive.When ground vertical direction moment of flexure is excessive, can protect major part effectively, only damage hold-down plate spring.

Shown in the accompanying drawing a kind of of the automatic hanging structure of such railroad vehicle.Fig. 1 is the overall main cutaway view behind main attaching parts and the Connector Clip pin joint, and Fig. 2 is its birds-eye view.

This automatic hanging structure, the automatic pin joint end of main attaching parts (1) is infundibulate, except that having pin-and-hole, also has the hole by touch part on the hopper walls, can utilize the hole size shape to limit the action radius of touch part.The other end of main attaching parts is fork-shaped and has the hole, so that directly be loaded on vehicle, available bearing pin (24) or bolt are connected with vehicle.The relative vehicle of main attaching parts has certain slewing area.Connector Clip is hinged with commutation head (2), and jointed shaft is vertical with pin, and hold-down plate spring (21) is equipped with in the commutation parallel with a jointed shaft side, and hold-down plate spring is fixedly connected on the commutation joint by bolt (19) pad (20).The other end of commutation joint also is fork-shaped and has the hole, so that directly be loaded on vehicle, available bearing pin (24) or bolt are connected with vehicle, and vehicle has certain slewing area relatively.When main attaching parts, Connector Clip released state, for the pin-and-hole of the automatic pin joint that makes both is positioned at the center line of vehicle separately, main attaching parts, the same respectively vehicle center line both sides separately of commutation joint are connected with two tension springs (25), do the time spent in no big external force, automatically the pin-and-hole of pin joint remains on center line, so that when articulating automatically, Connector Clip inserts the funnel end of main attaching parts exactly.Interlinked mechanism is that the housing (18) by interlinked mechanism is hinged with on main attaching parts.Housing is equipped with locating dowel pin (4,10).Touch part (6) is shaft-like, and an end is crotch shape, and the other end is positioned at funnel chamber by hopper walls, and bar is equipped with turning cylinder (3), and turning cylinder is loaded on housing (18), between touch part and the housing tension spring is housed.Attaching means is two parallel clamps (8), and shape is seen accompanying drawing.The touch part bar is between two plates.Clamp is equipped with turning cylinder (11), and turning cylinder is loaded on housing.One end of clamp has chute, and chute is equipped with cylindrical sliding part (7), is connected with tension spring (9) between sliding part and the housing.The other end of clamp can contact with the cutting ferrule (17) of pin, retrains it and moves downward.Cutting ferrule and pin are connected as a single entity, and pressure spring (15) is housed.The upper end of pin passes the hole of housing, is connected with handle (13) by nut (14).

This automatic hanging structure working process is: at main attaching parts, when Connector Clip separates, pin is mentioned, and is lived (position that the two-dot chain line of cutting ferrule is described) by cutting ferrule by the clamp constraint, and the touch part place is the position of two-dot chain line description in the drawings; When funnel chamber is inserted in the main relatively attaching parts motion of Connector Clip, the convex head of Connector Clip touches touch part, touch part drives clamp by sliding part and rotates counterclockwise, clamp leaves the position of constraint cutting ferrule, then cutting ferrule just moves downward together with pin, when the pin-and-hole of Connector Clip moved to the pin center position, pin inserted pin-and-hole, formed pin joint; In touch part, sliding part, clamp interlock later stage, touch part and sliding part break away from (position of seeing the two-dot chain line description of 1 pair of clamp of accompanying drawing, sliding part).Sliding part, clamp no longer are subjected to the effect of interlock power, get back to the position of constraint cutting ferrule before the former interlock under the elastic force effect; When mentioning pin, after being constrained by cutting ferrule, main attaching parts and Connector Clip are separable under external force; During separation, touch part is got back to former interlock front position under the elastic force effect; In the return process, touch part touches sliding part, and sliding part slides in chute, moves in the crotch outside the crotch of touch part relatively, slides go back to the bottom of chute and crotch at last under the elastic force effect again, is returned to the position before articulating automatically.
