Abstract
The present invention relates to a tractive connection mechanism of a lorry, in particular to a safety protection device for a draw gear of a freight train. A seat board is fixed under the end of a tractive beam of the lorry and an upper baffle and a lower baffle are welded on the seat board. A front baffle constituting a safety chain seat is welded before the upper baffle and the lower baffle. The front baffle is opened with a support hole, through which a buffer rod drills. The noumenon of the buffer rod is located in the safety chain seat and a buffer spring and an active stop dog are sleeved on the noumenon of the buffer rod. The other end of the buffer rod noumenon is a buffer rod head and the end of the buffer rod head is opened with a connecting hole. The buffer rod head is connected with a connecting link via a connecting hole. The link is connected with the head of the draw gear. The advantage is that the present invention can provide the emergency protective measures for the draw gear of the tractive train and ensure the safety of the train furthest.
Description
Technical field
The present invention relates to a kind of railway truck traction and connect on-hook structure, the especially safety guard of railway freight car hitch.
Background technology
As everyone knows, owing to there are very big difference in countries in the world railway road conditions, rolling stock maintenance system, the condition of public security etc., the application operating mode of railway truck is far from it.The country that has because poor, the rolling stock of railway road conditions maintenance system is unsound, social security disorderly, cause that technology state of vehicle is poor, parts are lost, badly broken, critical component fault rate height seriously jeopardizes traffic safety.Therefore, need take the necessary security safeguard to some critical component that may jeopardize traffic safety, to guarantee the traffic safety of train.
Summary of the invention
The problem to be solved in the present invention is exactly to provide a kind of safety device that is applicable to railway freight-car coupler---safety hook-chain mechanism at above demand, during coupling of vehicles, the safety hook-chain mechanism that is installed in every joint vehicle two ends is also even hung with adjacent shackles immediately, to guarantee the traffic safety of train.The employing technical scheme is as follows:
It is a fixed base plate below railway truck draw beam end, and assembly welding has overhead gage and lower baffle plate on seat board, is welded with front apron in the previous groups of upper and lower baffle plate and constitutes the snubber chain seat.On front apron, have supported hole, pass a shock strut body through supported hole and be positioned at the snubber chain seat, be set with recoil spring and active block stop on the shock strut body in the snubber chain seat.The shock strut body other end is the shock strut head, and the end of shock strut head has connecting bore, and by the connecting bore lugless joining shackle, chain link is connected with gib head.
The present invention has following advantage:
1, train is in the operation way; when causing hitch to lose efficacy separation for a certain reason; because the traction of safety hook-chain mechanism connects the extension effect; train still can continue to connect extension and move to the safety stop circuit; be unlikely to separate the parking separation accident of train that cause at mainline railway because hitch loses efficacy; the emergency protection measure is provided for the hitch of tractor-trailer train, at utmost ensures train traffic safety.2, easy to use, safe and reliable.3, simple in structure, easy to maintenance.4, recoil spring adopts gauge member, and commonality is good, and maintenance is simple.

Among the figure, the 1st, snubber chain seat, the 1.1st, seat board, the 1.2nd, front apron, the 1.3rd, overhead gage, the 1.4th, lower baffle plate; The 2nd, snubber chain device, the 2.1st, shock strut body, the 2.11st, shock strut head, the 2.2nd, gib head, the 2.3rd, chain link, the 2.4th, connecting bore, the 2.5th, boss; The 3rd, recoil spring; The 4th, active block stop; The 5th, the railway truck hook; The 6th, railway truck draw beam, the 6.1st, mounting hole; The 7th, hitch.
The specific embodiment
Referring to Fig. 1-Fig. 6, the present invention connects seat board 1.1 by mounting hole 6.1 usefulness bolts or rivet below railway truck draw beam 6 ends.Assembly welding has overhead gage 1.3 and the lower baffle plate 1.4 that is parallel to each other on seat board 1.1, is welded with the front apron vertical with upper and lower baffle plate 1.2 in the previous groups of upper and lower baffle plate, and overhead gage 1.3, lower baffle plate 1.4 and front apron 1.2 constitute snubber chain seats 1.On front apron 1.2, have supported hole 1.21, pass a shock strut body 2.1 through supported hole 1.21 and be positioned at snubber chain seat 1, be set with recoil spring 3, active block stop 4 and nut, female, the spring cotter of the locking back of the body on the shock strut body 2.1 in snubber chain seat 1, active block stop 4 is vertically between overhead gage 1.3 and lower baffle plate 1.4.Supported hole 1.21 is the rectangle supported hole, and the cross section of shock strut body 2.1 is a rectangle.Recoil spring 3 is the buffer mediums that adopt the gauge member disk spring to form.The shock strut body other end is a shock strut head 2.11, be positioned at outside the snubber chain seat 1, the end of shock strut head is an annulus, the center of annulus constitutes connecting bore 2.4, the neck of shock strut head and shock strut body engagement place have boss 2.5, connect the chain link 2.3 that interlocks more than two by connecting bore 2.4, chain link 2.3 is connected with gib head 2.2, constitutes flexible chain hook.On the railway truck end carriage, rivet or be welded with hook 5.
Principle of work of the present invention is as follows: during coupling of vehicles, and hitch and be installed in the safety hook-chain mechanism at every joint vehicle two ends and adjacent shackles connects extension simultaneously.Safety hook-chain mechanism plays the security insurance effect.
Train is in the operation way, when causing hitch to lose efficacy separation for a certain reason, because the traction of safety hook-chain mechanism connects the extension effect, train still can continue to connect extension and move to the safety stop circuit, is unlikely to separate the parking separation accident of train at mainline railway that cause because hitch loses efficacy.The emergency protection measure is provided for the hitch of tractor-trailer train.
Safety hook-chain mechanism connects when hanging, and gib head 2.2 connects on the gib head 2.2 that hangs over adjacent safety hook-chain or on the chain link 2.3.Safety hook-chain mechanism is when being subjected to tractive force, the pulling force of gib head 2.2 is delivered to the head 2.11 of shock strut body 2.1 by chain link 2.3, drive shock strut body 2.1 with respect to snubber chain seat moving by a small margin, simultaneously since the supported hole 1.21 of front apron 1.2 match with the square-section of shock strut body 2.1 front ends, make chain hook be subjected to pulling force after shock strut body 2.1 can only move forward and backward and can not rotate.Drive active block stop 4 compression recoil springs 3 when shock strut body 2.1 is subjected to pulling force, because the buffering shock damping action of recoil spring 3, consume and absorbed most of kinetic energy, slowed down the rigid shock power of chain hook greatly, realized the function of chain hitch.The shackles that interconnection is mutually hung can not decompose disengaging automatically, the reliability that the company of assurance hangs.Safety hook-chain mechanism is in non-company when hanging state, and gib head 2.2 hangs on the hook 5 and gets final product.
