Abstract
The utility model discloses an upper sliding groove device pulling rod device of a railway vehicle brake 120 releasing valve, comprising a releasing valve handle of the brake 120; wherein, the lower hinge pin of the releasing valve handle is connected with the upper sliding chute of a vertical rocker arm and can move in the sliding chute; the middle part of the vertical rocker arm is hinged with a fixing bracket, which is connected with the railway vehicle body; the lower part of the vertical rocker arm is connected with the head of a horizontal pulling rod, and the handle part of the horizontal pulling rod is suited into the pulling rod lifting hole. More particularly, the lower end of the vertical rocker arm is hinged with the head of the horizontal pulling rod to form a sliding block rocker arm pulling rod driving device; the lower end of the vertical rocker arm can also be fixedly connected with the head of the horizontal pulling rod to form an integral type rocker arm pulling rod. The pulling rod device can make the worker control the releasing valve handle freely under the normal standing condition, to insure the braking system should exhaust and the vehicle under the braking condition should rapidly release.
Description
Technical field
The utility model relates to the device of handling railway vehicle 120 air damper release valve handles, refers to a kind of rolling stock 120 brake release valve upper hopper chute mechanism formula pull rod device particularly.
Background technology
At present, the controller of generation braking and mitigation is mainly 120 air dampers in China railways vehicle operating and the parking.The release valve handle of this brake is handled by manually pulling mode, the railroader pulls the release valve handle about by the release valve pull bar, the pressurized air of brake system is discharged from escape orifice, thereby make the vehicle that is in braking mode reach the purpose of alleviation.
On the rolling stock of general type, during the normal release valve handle of handling 120 air dampers, consider from principle, the power that the applies F of release valve pull bar can with horizontal surface γ in an angle, only apply the horizontal force F of power F
XThe release valve handle is rotated, general F
X=Fsin (γ), γ is more little, and the required power that applies F is also big more.Therefore, have only when the release valve pull bar is in certain scope, could operate the release valve handle easily.During less than 90 ℃, after the power F of applying makes the release valve handle leave neutral position, γ will become greatly, then firmly can reduce at the initial condition of γ.And when the initial condition of γ during greater than 90 ℃, after the power F of applying makes the release valve handle leave neutral position, γ will become greatly, and exerting oneself this moment need increasing.This shows the limitation of existing release valve pull bar manipulation release valve handle.
For the rolling stock of tank car type, the release valve pull bar of handling its 120 air damper release valve handle generally is arranged in two orientation, and the first is arranged in the release valve pull bar of IV position, and it two is the release valve pull bars that are arranged in the III position.Because the angle of IV position release valve pull bar and release valve handle is near 90 ℃, pulling is out of question.But for III position release valve pull bar, the angle of itself and release valve handle is greater than 150 ℃, and the ground-surface height of release valve pull bar actual distance only is more than 1 meter, staff's general custom donation power F that makes progress causes producing positive pressure N between release valve pull bar and the pull bar hanging sleeve ring, thereby produces friction force f, directed force F is big more, positive pressure N is big more, thereby friction force f is big more, makes to be difficult to pulling release valve handle in actual applications.
Summary of the invention
Aim of the present utility model is that the existing existing deficiency of release valve pull bar is improved, and proposes a kind of staff and can handle the release valve handle easily under the normal stand state, guarantee the rolling stock 120 brake release valve upper hopper chute mechanism formula pull rod device that the brake system exhaust is alleviated.
For achieving the above object, the rolling stock 120 brake release valve upper hopper chute mechanism formula pull rod device that the utility model is designed, the release valve handle that comprises 120 brakes, the lower end swivel pin of described release valve handle links to each other with the upper end chute of vertical rocking arm, can in chute, relatively move, the middle part and the fixed bearing of described vertical rocking arm are hinged, described fixed bearing is connected on the car body of rolling stock, the lower end of described vertical rocking arm links to each other with the head of girt, and the handle portion of described girt is inserted in the pull bar lifting hole(eyelet).Particularly, the lower end of described vertical rocking arm and the head of girt are hinged and connected, to form a slide block rocking arm pull bar driver train; The lower end of described vertical rocking arm also can be fixedly linked with the head of girt, forms all-in-one-piece rocking arm pull bar, and should suitably strengthen the size of pull bar lifting hole(eyelet) this moment, to guarantee the rocking arm drag link mechanism enough rotation spaces is arranged when moving.
Advantage of the present utility model is: designed pull rod device has made full use of the motion principle of slide block, rocking arm and pull bar combination mechanism, efficiently solves original pull bar and is easy to generate deadlock phenomenon in operating process, causes the abnormal defective of brake release valve exhaust.The staff operates in any case, can not make the pull rod device on the go lock-up condition occur.And, by adjusting the dimensional parameters of girt, vertical rocking arm or chute, both can be laborsaving, can increase the sensitivity of brake release valve exhaust again, thereby make the staff under the normal stand situation, can handle the release valve handle easily, guarantee the rapid exhaust alleviation of vehicle.
Description of drawings

Fig. 2 is the structural representation of another kind of rolling stock 120 brake release valve upper hopper chute mechanism formula pull rod device
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Rolling stock 120 brake release valve upper hopper chute mechanism formula pull rod device as shown in Figure 1, the release valve handle 1 that comprises 120 brakes, the lower end swivel pin of this release valve handle 1 links to each other with the upper end chute 4 of vertical Rocker arm 5, the middle part and the fixed bearing 2 of vertical Rocker arm 5 are hinged, fixed bearing 2 is connected on the car body of rolling stock, the lower end of vertical Rocker arm 5 and the head of girt 6 are hinged and connected, and the handle portion of girt 6 is inserted in pull bar lifting hole(eyelet) 3.During this pull rod device work, by push-and-pull girt 6, make its sway in pull bar lifting hole(eyelet) 3, and vertical Rocker arm 5 is rotated around fixed bearing 2, thereby make chute 4 drive the lower end swivel pin sway of release valve handle 1, and then make release valve handle 1 left-right rotation, the purpose that makes 120 air damper release valve exhausts to reach, vehicle is alleviated.At this moment, pull bar lifting hole(eyelet) 3 mainly play the guiding role.
Rolling stock 120 brake release valve upper hopper chute mechanism formula pull rod device as shown in Figure 2, its agent structure and pull rod device shown in Figure 1 are basic identical, be that the head of lower end and the girt 6 of vertical Rocker arm 5 adopts and captives joint mode, as welding or itself making one, form a rocking arm pull bar.During this pull rod device work, by push-and-pull rocking arm pull bar, it is rotated around fixed bearing 2, thereby make chute 4 drive the lower end swivel pin sway of release valve handle 1, and then make release valve handle 1 left-right rotation, reach the purpose that 120 air damper release valve exhausts, vehicle are alleviated.In order to guarantee that the rocking arm pull bar has enough mobile spaces, pull bar lifting hole(eyelet) 3 will leave enough vacant amounts, and pull bar lifting hole(eyelet) 3 only plays antitheft effect at this moment.
