Abstract

This invention relates to the field of railway transport. The purpose of the invention is to increase reliability by reducing the vertical loads on the console frame. The thrust rod is placed horizontally in the transport position. At its free end there is a longitudinal yusha, in which the hinge of the lower arm of the two shoulders is mounted. The other shoulder of the last stage is connected to the side of the body. Two shoulders lever pivotally mounted on the vehicle body. 3 il.

accompanied by a limited longitudinal movement of the lower arm 9 of the two shoulders lever 3 in the guide 10 of the thrust rod 4. The relative position of the opposite side 4, its locking mechanism and the body frame 5 remains unchanged throughout the whole tilt of the body frame.

When the body frame 5 returns to its original position after unloading the shoulder 9 of the two shoulders lever 3 along the guide 10

The invention relates to railway transport, namely to the construction of heavy-duty dump trucks.

The purpose of the invention is to increase reliability by reducing the vertical loads on the console frame.

FIG. 1 schematically shows the proposed device, the transport position; in fig. 2 - the position of the body prior to the beginning of the load; in fig. The 3-position of the body at the time of the full 10 comes to contact with the persistent load. Go to 4. Before this happens closing

The device contains a hinged connection angle “i by an amount less than 180 °. In the interconnected tug 1, bead 2, as a result of further lowering of the body and double-arm lever 3 and thrust rod 4. The bottom-engagement of the arms of the closing-shoulder lever 3 is hinged on the wound and opening the bead occurs on the body 5, and persistent t ha 4 shchar- - - -

nirnally connected to the console 6 of the frame 7. One shoulder 8 of the two shoulders lever 3 is hingedly connected to the thrust of 1 side 2, and the lower shoulder 9 is hingedly connected to the thrust thrust 4 with the possibility of limited longitudinal 20th mechanism of locking the opposite movement in the longitudinal direction side when tilting the body around the axis A |. 10 thrust rods 4. In the transport position of the bead 2, the thrust bar ha 4 is located in the horizontal plane, which I excludes the possibility of transferring vertical loads on the console 6 of the frame 7 25 from the load stresses to the board 2.

When unloading frame 5 bodywork force

with one end of a two-armed lever pivotally fixed on the body, and a thrust rod mounted on the console of the frame, the free end of which is pivotally

around the point “b. When the body is tilted up, it is connected to the other end of the two-armed lever, the position corresponding to the beginning of the union, characterized in that, in order to lower the load about 30 °), there is a complete increase in reliability by reducing the vertical opening of the side 2 and opening the angle ai of the frame loads on the console of the frame, the abutment I to a value close to 180 °. At the same time, on a ha, a horizontal mechanism of opening and closing the side of the plane is placed in the transport position and is released, and the side is held in the opposite of the longitudinal guide, in which the closed position by the stops 11, is arranged with a body limited by women on the frame 5. . Further movement of the hinge of the lower arm of the two-tilt body until the full load of the shoulder arm is full.

Similar to the operation, the relative position of the first side, its mechanism of closing and opening and the frame 5 of the body remain unchanged.

Claims (1)

Invention Formula metrics of the lower arm of the two-arm corner lever 3 and the thrust rod gi 4, followed by the rotation of the two-arm lever 3 around the point a, and the thrust rod 4 around the point AI. Board 2 opens accompanied by a limited longitudinal movement of the lower arm 9 of the two shoulders lever 3 in the guide 10 of the thrust rod 4. The relative position of the opposite side 4, its locking mechanism and the body frame 5 remains unchanged throughout the whole tilt of the body frame. When the body frame 5 returns to its original position after unloading the shoulder 9 of the two shoulders lever 3 along the guide 10 comes in contact with the thrust 4. Before this, there is a closing the opening of the board takes place - - - The mechanism locks the opposite side when the body is tilted around the axis A |. mouth bead 2 around the point “b to its original position. The relative position of the opposite side 4, its locking mechanism and the frame 5 of the body remains unchanged. Similarly, the mechanism of locking the opposite side acts when the body is tilted around the axis A |. At the same time, the relative position of the first side, its mechanism of closing and opening and the frame 5 of the body remains unchanged. Invention Formula 2 0ue.J
