Detailed Description

The present invention will be further described in the following to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the present invention easy to understand.

As shown in fig. 1 to 5, an emergency breaking preventing device for a railway car comprises a connecting plate 1 fixed at the bottom of the railway car 11 and a guiding trolley 2 hinged to the connecting plate 1, wherein long rods 3 swinging back and forth are hinged to the guiding trolley 2, supporting rods 4 which are symmetrically distributed and telescopic are arranged on the left side and the right side of the long rods 3, connecting rods 5 with one ends hinged to the tops of the long rods 3 and the other ends hinged to the supporting rods 4 are arranged on the left side and the right side of the long rods 3, a first block 6 which is horizontally and slidably mounted on the connecting plate 1 is hinged to one end of the supporting rods 4, a second block 7 which is horizontally and slidably mounted on the guiding trolley 2 is hinged to the other end of the supporting rods 4, a first semicircular ring plate 8 is arranged on the left side and the right side of the guiding trolley 2, and a plurality of pins 10 which are uniformly distributed at intervals in the circumferential direction are arranged on the first semicircular ring plate 8 and the second semicircular ring plate 9.

Through the mode, when the guide trolley 2 pulls the rail trolley 11, the first block 6 and the second block 7 are combined, so that the long rod 3 and the support rod 4 can rotate along with the guide trolley 2 and the rail trolley 11, the connection strength between the guide trolley 2 and the rail trolley 11 can be enhanced, the working load of the connecting plate 1 is reduced, the normal work of the rail trolley 11 is not influenced, when the guide trolley 2 and the rail trolley 11 are broken, the guide trolley 2 drags the long rod 3 to move downwards, the support rods 4 on two sides are pushed by the connecting rod 5 to slide, the support rods 4 are clamped between the pin posts 10 on the first semicircular plate 8 and the second semicircular plate 9, the support rods 4 are fixed, and at the moment, the support rods 4 bear most acting force between the guide trolley 2 and the rail trolley 11, so that the emergency braking reaction time is provided, the braking safety is improved, and the support rods 4 can be clamped into the pin posts 10 under any working angle of the guide trolley 2.

The support rod 4 comprises a first rod 41 connected with the first block 6 and a second rod 42 connected with the second block 7, a sliding groove 411 is arranged on the first rod 41, a limiting shoulder 412 is arranged at the bottom of the sliding groove 411, a sliding rod 421 matched with the sliding groove 411 is connected to the second rod 42, a boss 422 is fixed to the top of the sliding rod 421, and a spring 43 positioned between the boss 422 and the limiting shoulder 412 is sleeved on the sliding rod 421.
