Abstract
The utility model discloses a four-link mechanism pull rod of railway vehicle 120 brake release valve, which comprises a release valve handle of 120 brake. The release valve handle is hinged to one end of the level connecting rod; the other end of the level connecting rod is hinged to one end of a rocker arm .The middle part of the rocker arm is hinged with a fixed support and the fixed support is connected with the railway vehicle body. The other end of the rocker arm is connected with the head of the level connecting rod and the handle part of the level connecting rod is inserted in the hoisting hole of the pull rod. Substantially, the other end of the rocker arm can be hinged with the head part of the level connecting rod to form a four-link driving mechanism. The other end of the rocker arm can also be connected fixedly with the head part of the level connecting rod to form an integral rocker arm pull rod. The pull rod can let the workers operate the handle of the release valve easily in a normal standing status to ensure the braking system to exhaust and relieve the vehicle quickly in the braking condition.
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 four-bar linkage 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
The purpose of this utility model will overcome the existing existing defective of release valve pull bar exactly, provides a kind of staff can handle the release valve handle easily under the normal stand state, guarantees the rolling stock 120 brake release valve four-bar linkage formula pull rod device that the brake system exhaust is alleviated.
For achieving the above object, the rolling stock 120 brake release valve four-bar linkage formula pull rod device that the utility model is designed, the release valve handle that comprises 120 brakes, one end of described release valve handle and waling stripe is hinged, one end of the other end of described waling stripe and rocking arm is hinged, the middle part and the fixed bearing of described rocking arm are hinged, described fixed bearing is connected on the car body of rolling stock, the other end of described 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 other end of described rocking arm can be hinged and connected with the head of girt, to form one four bar-link drive; The other end of described 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 connecting rod mechanism, efficiently solves original pull bar and is easy to generate deadlock phenomenon in operating process, causes the abnormal deficiency 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 ratio of waling stripe, rocking arm or girt, 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.

Fig. 2 is the structural representation of another kind of rolling stock 120 brake release valve four-bar linkage 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 four-bar linkage formula pull rod device as shown in Figure 1, the release valve handle 1 that comprises 120 brakes, this release valve handle 1 is hinged with an end of waling stripe 4, one end of the other end of waling stripe 4 and Rocker arm 5 is hinged; the middle part of Rocker arm 5 and fixed bearing 2 are hinged; fixed bearing 2 is connected on the car body of rolling stock, and the head of the other end of Rocker arm 5 and girt 6 is 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 Rocker arm 5 is rotated around fixed bearing 2, thereby drive waling stripe 4 sway, and then make release valve handle 1 left-right rotation, with the purpose that reaches 120 air damper release valve exhausts, vehicle is alleviated.At this moment, because Rocker arm 5 rotates around fixed bearing 2, make girt 6 that certain moving up and down be arranged, hinged between girt 6 and the Rocker arm 5 can make girt 6 and Rocker arm 5 relatively rotate.Pull bar lifting hole(eyelet) 3 mainly play the guiding role.
Rolling stock 120 brake release valve four-bar linkage formula pull rod device as shown in Figure 2, its agent structure and pull rod device shown in Figure 1 are basic identical, just the other end of Rocker arm 5 is captiveed joint mode with the head employing of girt 6, as welding or itself making one, form a rocking arm pull bar.During this pull rod device work,, it is rotated around fixed bearing 2, thereby drive waling stripe 4 sway, and then make release valve handle 1 left-right rotation, reach the purpose that 120 air damper release valve exhausts, vehicle are alleviated by push-and-pull rocking arm pull bar.Because this rocking arm pull bar rotates around fixed bearing 2, the rocking arm pull bar is done at pull bar lifting hole(eyelet) 3 moved up and down, for guaranteeing the rocking arm pull bar enough mobile spaces are arranged, 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.
