Description

An adaptive device according to the variety of the load of rail freight}

The present invention relates to a dropping adjustment member installed on a freight vehicle of a train to operate a brake according to the weight of the freight vehicle, and in particular, to provide a dropping adjustment member of a freight train without trouble and easy to adjust its length.

As shown in FIG. 1A, the dip response adjusting member senses the height of the load sensing member 200 formed on the load supporting frame 120 supporting the load of the freight vehicle 100 by the elastic member 130. This is to check the existence of cargo in the vehicle (100) and to operate the brake. It is formed on the side frame of the cargo vehicle.

Among the freight vehicles of the train, the reason for installing the response tester on the freight vehicle 100 is that the brakes are pushed by the load of the cargo when the freight vehicle 100 is operated with the tolerance and when the freight is loaded. Two brakes (not shown in the drawing) are formed on the vehicle to prevent the vehicle from being stopped or suddenly stopped.When driving at a tolerance, only one brake is activated to prevent the vehicle from being stopped suddenly. It is used to activate two brakes in order to prevent the truck from being pushed.

As described above, in order to operate the brake by the presence or absence of the cargo, the side frame 110 of the freight vehicle 100 is formed with a dropping rate adjusting member 300, and supports the elasticity of the elastic member 130 while supporting the weight of the cargo. The load supporting frame 120, which is moved up and down while being supported by the load, has a load on which the sensing rod 210 is formed such that the load supporting frame 120 is brought into contact with the falling support adjusting member 300 when the load supporting frame 120 descends by the weight of the cargo. Both brakes operate only when the load supporting frame 120 is lowered by the load by forming the sensing member 200 and the sensing rod 210 of the load sensing member 200 is in contact with the falling support adjusting member 300. It is formed so as to eliminate the risk of safety accidents, the sensing rod 210 and the load sensing member 200 and the sensing rod 210 of the load sensing member 200 to operate only when the cargo is loaded on the cargo vehicle 100 is about 14mm Spacing the ball By moving a shake prevents the sensing rod 210 and eungha jeungbyeon adjustment member 300 in contact.

However, as the coagulation increase adjusting member is used as described above, a through groove is formed in the fixture 310 fixed to the side frame 110 as shown in FIG. 1B, and the nut is closely attached to the upper and lower portions of the through groove. It is formed as a nut in the state, while the upper portion of the support plate 322 in contact with the sensing rod 210 of the load sensing member 200 through the feed groove 321 is formed in the upper through the through groove of the fixture 310 It is inserted and fixed to the nut or used to adjust the length. However, since the feed shaft 321 formed by the nut and the nut are exposed to the outside, foreign matter gets stuck between the feed shaft 321 and the nut, and thus cannot operate well. , Because it is exposed to the outside and rainwater is easily introduced, the feed shaft 321 and the nut are corroded, and the adjusting tool 320 is formed in such a way that a tool such as a wrench cannot be used in the adjusting tool 320 in which the support plate 322 is formed. Joe There is a problem that can not be bowed.

As described above, when the coagulation test adjustment member 300 cannot be adjusted due to corrosion or foreign matter, and the gap between the coagulation test adjustment member 300 and the sensing rod 210 of the load sensing member 200 cannot be maintained at an appropriate interval. Because the cutting shaft 321 of the increase and decrease adjustment member 300 can not be used to increase or decrease the length, the corresponding increase and decrease adjustment member 300 is easily broken, and there is a problem that is not good to see.

The present invention has been made to solve the above problems, to prevent foreign matter from flowing into the charge increase adjustment member to provide a response change adjustment member of the freight train can always adjust the distance to the load sensing member constant will be.

The present invention is to provide a cargo response control member of the freight train that can always adjust the distance to the load sensing member constant, so that it does not have to damage the response monitor adjustment member to adjust the distance.

In addition, by using a wrench to provide a control gear of the cargo response can be adjusted while easily rotating the adjustment sphere.

In accordance with the present invention for achieving the above object, the load response adjusting member of a freight train includes a load supporting frame for supporting a load of a cargo by an elastic member placed on a side frame of the freight vehicle, and at one end of the load supporting frame. In a freight vehicle of a train having a load sensing member having a sensing rod formed thereon to activate a brake:
