Abstract
The invention relates to a telescopic mechanism of a telescopic coupler and buffer device for a high-speed motor train unit. The telescopic mechanism comprises a pressed rod which is positioned at one end in a movable shell of the coupler and buffer device and connected with the movable shell, and a bearing joint sleeved on the pressed rod, wherein a guide cylinder is fixedly arranged outside the bearing joint; a telescopic driving mechanism is arranged between the guide cylinder and the movable shell; one end of the pressed rod is connected with the movable shell through a torsion spring; the pressed rod and the bearing joint are locked; a locking mechanism comprises convex heads which are positioned at the other end of the pressed rod and distributed at intervals, and grooves which are positioned on the inner wall of the bearing joint and fitted with the convex heads; when the convex heads are opposite to the grooves, the pressed rod and the bearing joint are unlocked and can relatively slide; and an unlocking driving mechanism is arranged outside the movable shell. The corresponding parts are arranged in the movable shell, so the occupied space is small, and the corresponding parts are well protected; meanwhile, the telescopic mechanism and the locking mechanism have relatively simple structures, are labor-saving and high in action reliability and can bear a high longitudinal load, and the impact energy absorption capacity of a buffer system is relatively high. After the telescopic mechanism is applied, the telescopic coupler and buffer device can be localized and completely replaces imported products.
Description
Technical field
The present invention relates to the slow equipment of a kind of railway vehicle hook, especially a kind of EMU of the portion end to end that is installed in EMU is with telescopic coupler buffering device telescoping mechanism.
Background technology
Coupler buffering device is one of railway vehicle basic element of character, play quick connection and decompose railway vehicle, transmit tractive force of train, improve vehicle safety, improve vehicle riding comfort can effect.
When telescopic coupler buffering device is not worked, be in the streamlined reefer housing of EMU head car, need to connect in the time of hanging then to stretch out so that realize between train in the streamlined reefer housing and connect to reduce the air resistance etc. in the train operation.EMU is external product at the telescopic coupler buffering device of usefulness at present, and price is higher, and delivery cycle is longer, especially the supply side of standby redundancy; Be limited by external present situation for solving telescopic coupler buffering device, fill the domestic gaps, carry out the development of telescopic coupler buffering device.Gordian technique in the telescopic coupler buffering device is exactly telescopic drive and the flexible locking and the function that unlocks of putting in place.
Having of usefulness following two kinds at present, a kind of is the telescopic coupler buffering devices that are used in 16 manual forms on the marshalling motor train unit, and another kind is the automatic telescopic coupler buffering device that is used in 8 pneumatic actuation in the marshalling, and product is external product.What the telescopic drive of external manual telescopic coupler buffering device adopted is the transmission of external rack-and-gear, and release mechanism also is an external, and the ability of buffer system absorption impact energy is less relatively, and overall structure takes up room greatly, flexible complicated with latch-up structure.
Summary of the invention
The object of the present invention is to provide a kind of EMU to use telescopic coupler buffering device, be installed in the portion end to end of EMU, be in the stream line pattern streamlined reefer housing of a car, be used for connection or rescue between the motor train unit.When train did not heavily join, coupler buffering device was in withdrawal situation and locking; When train heavily joins, at first open streamlined reefer housing, operate telescoping mechanism then hitch is stretched out, stretch out the back locking that puts in place, can carry out hitch and connect extension; After train decomposed, the operation telescoping mechanism made the hitch withdrawal, and streamlined reefer housing is closed in locking after withdrawal puts in place at last.In said process, the stretching out of hitch, locking and withdrawal, lock function etc. are accomplished by the telescoping mechanism of coupler buffering device.In the train coupled running process, telescoping mechanism need bear bigger stretching and clamp load.
Technical scheme of the present invention is: a kind of EMU is with telescopic coupler buffering device telescoping mechanism; Described telescoping mechanism comprises and is positioned at coupler buffering device movable housing inner an end and movable housing bonded assembly compression rod, is set in the carrying joint on the compression rod; Carry the joint outside and be fixed with guide cylinder, be provided with telescopic drive mechanism between guide cylinder and the movable housing; One end of compression rod joins through torsion spring and movable housing, keeps compression rod and carrying joint to be in the lock state; Lockout mechanism comprises the plush copper spaced apart that is positioned at the compression rod other end, carry the groove that matches with plush copper of the inwall of joint, when plush copper is relative with groove, is in released state, but the two slide relative; Described movable housing outer setting has unlock drive mechanism.
Preferably: described telescopic drive mechanism comprises and is positioned at the flexible gear on the movable housing and is installed in the flexible tooth bar on the guide cylinder.
Preferably: described unlock drive mechanism comprises the steel rope that is installed on the compression rod and can drives its rotation.
Preferably: described plush copper and groove are for being equally spaced.
Preferably: the shape of described plush copper is identical.
Preferably: the shape of described groove is identical.
Preferably: described carrying joint groove is provided with limiting block.
Beneficial effect of the present invention is: corresponding component of the present invention all is arranged at movable housing inside; It is little to take up room; Protective value to corresponding component is better, and simple relatively, laborsaving on flexible simultaneously and the lockout mechanism structure, reliable in action property is high; Can bear bigger longitudinal loading, the ability of buffer system absorption impact energy is relatively large.After the present invention used, telescopic coupler buffering device can be realized production domesticization, complete import substitutes.

The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present invention:
A kind of EMU is with telescopic coupler buffering device telescoping mechanism; Described telescoping mechanism comprises and is positioned at coupler buffering device movable housing 1 an inner end and movable housing 1 bonded assembly compression rod 2, is set in the carrying joint 3 on the compression rod 2; Carry joint 3 outsides and be fixed with guide cylinder 4; Be provided with telescopic drive mechanism 9 between guide cylinder 4 and the movable housing 1, described telescopic drive mechanism comprises and is positioned at the flexible gear 10 on the movable housing 1 and is installed in the flexible tooth bar 11 on the guide cylinder 4; One end of compression rod 2 joins through torsion spring 5 and movable housing 1, keeps compression rod 2 and carrying joint 3 to be in the lock state; Lockout mechanism comprises the plush copper spaced apart 6 that is positioned at compression rod 2 other ends, carry the groove 7 that matches with plush copper 6 of the inwall of joint 3; Described plush copper 6 and groove 7 are for being equally spaced; The shape of described plush copper 6 is identical, and the shape of described groove 7 is identical.When plush copper 6 relatively the time, is in released state with groove 7, but the two slide relative; Described movable housing 1 outer setting has unlock drive mechanism 8, and described unlock drive mechanism comprises the steel rope that is installed on the compression rod 2 and can drives its rotation.Described carrying joint 3 grooves 7 places are provided with limiting block 12.
