Abstract

The invention provides a traction sleeper device comprising a traction beam and sleeper beams; the sleeper beams are symmetrically arranged at both sides of the traction beam; the sleeper beams comprise web plates and lower cover plates arranged below the web plates; the traction sleeper device is characterized in that the sleeper beams also comprise reinforcing rib plates; the reinforcing rib plates are arranged on the web plates; transverse and longitudinal reinforcing rib plates and side-bearing reinforcing rib plates are added to the positions of the web plates of the sleeper beams of the traction sleeper device so as to form a box-shaped integral bearing structure, and the defect of high stress level of the joint of the web plates and a traction beam of a traction sleeper structure of a tank car of a traditional railway in China under the working condition of longitudinal and vertical loads is overcome; and moreover, a supporting post of a short side pipe is arranged, an original supporting post structure of a side pipe is changed, the center of the circle of the supporting post of the short side pipe is arranged along a radial direction, the wrap angle is increased, the diameter is increased, the stress concentration level of the nearby position of the upper end of the supporting post of the side pipe of an original structure is lowered, car jacking beams are arranged and are in grouped welding to form a box-shaped structure with favorable stress, and the stress concentration level of the nearby position of the upper end of the supporting post of the side pipe of the original structure is lowered.

Description

Technical field

[0001] The invention relates to a pillow holding device of a tank car. Background technique

[0002] At present, the railroad tank car in my country is widely used in the traction sleeper structure without center beam. The transmission path of the longitudinal load on the single tank car is: one end coupler-sleeper device-lower part of the tank-the other end sleeper device-the other end coupler . While transmitting the longitudinal load between the vehicles, the pillow device also supports the tank and bears the vertical load. Take the 70-ton-class railway tank car as an example. In my country's railway freight car assessment standards, the maximum longitudinal load is 250 tons, and the vertical static load is 70 tons. At the same time, it must bear the effects of saturated vapor pressure and liquid shock pressure. bad.

[0003] The harsh working conditions have brought a greater impact on the force of the traction device, and there are mainly the following two pro...

Embodiment Construction

[0025] See figure 1 , The preferred embodiment of a pillow-traction device involved in the present invention is:

[0026] The device mainly includes an end beam 1, a side beam 2, a traction beam 3, and a corbel 4; the side beam 2 is vertically connected to both ends of the end beam 1; the traction beam 3 is vertically arranged in the middle of the end beam 1; the corbel 4 is symmetric It is arranged on both sides of the traction beam 3, and its other end is connected with the other end of the side beam 2. The end beam 1, the side beam 2, and the traction beam 3 can all adopt the structure in the prior art; the corbel 4 of the present invention includes a web The plate 6, the lower cover plate 7 arranged under the web 6 and the stiffener plate; the stiffener plate can be arranged vertically on the web 6, which can reduce the longitudinal and vertical load at the connection between the web 6 and the traction beam 3 Stress under working conditions.

[0027] The stiffener plate of the...
