Description

Railway ballast tamping method and railway ballast multifunctional tamping device

Technical Field

The invention relates to a railway overhaul method, in particular to a railway ballast tamping method. The invention also relates to railway overhaul equipment, in particular to a multifunctional tamping device for railway ballast.

Background

The tamping car is an operation machine for tamping stone ballast in a track bed, and is used for shifting, lifting and tamping a track, so that the direction, the left and right level, the front and back height of the track can meet the requirements of a line design standard or a line maintenance rule, the compactness of the stone ballast of the track bed is improved, the stability of the track is increased, and the safe operation of a train is ensured.

At present, railway switch district, main track railway tiny fragments of stone, etc. are tamped domestically and abroad respectively and are adopted switch tamping car and circuit tamping car to the biggest operation width (by circuit center) is only 3300mm during switch tamping car operation, makes a set of 12 switches of tamping need carry out tamping respectively from two directions, and the tamping operation is inefficient, and the circuit state is poor after the operation.

Disclosure of Invention

The invention aims to solve the problems that the tamping width of turnouts of the existing tamping car is small and a group of No. 12 turnouts cannot be completely tamped at one time, provides a method for continuously completing ballast tamping operation at turnout areas and the bottoms of main sleepers at one time, and provides a multifunctional tamping device for realizing the method.

The invention is realized by the following technical scheme:

a railway ballast tamping method is characterized in that railway switch area ballast is tamped while railway main track ballast is tamped.

The utility model provides a multi-functional tamping unit of railway ballast, includes the main tamping unit who smashes railway main track ballast, characterized by still includes the supplementary tamping unit who smashes railway switch district's track ballast simultaneously.

Preferably, the auxiliary tamping device comprises a rotary base, a vertical arm positioned on the rotary base, a transverse arm hinged with the vertical arm, and a tamping arm hinged with the transverse arm, wherein the end part of the tamping arm is hinged with a tamping pick assembly, and the vertical arm, the transverse arm and the tamping arm are respectively provided with a driving oil cylinder.

Preferably, the auxiliary tamping device is a small tamping machine which is positioned on the tamping vehicle, an engine of the small tamping machine is an electric motor, a power supply is provided from the tamping vehicle to drive the electric motor to work, and the small tamping machine is not mechanically connected with the tamping vehicle.

The equipment can continuously complete ballast tamping operation at the turnout area and the bottom of the main track sleeper, and the maximum operation width (measured by the center of a line) is 3500mm, thereby realizing the purpose of tamping the whole set of No. 12 turnouts at one time.

Detailed Description

As shown in fig. 1, the railway ballast tamping method of the invention is used for tamping a railway ballast A on a railway main track and simultaneously tamping a railway ballast B on a railway turnout area.

As shown in fig. 2 and 3, in order to realize tamping of railway main track ballast and tamping of railway turnout area ballast, the invention provides a multifunctional tamping device, wherein an auxiliary tamping device 1 is added on an original railway tamping car for tamping railway main track ballast, and the auxiliary tamping device 1 and a main tamping device on the railway tamping car work simultaneously, so that railway turnout area ballast B can be tamped while railway main track ballast A is tamped.

As shown in fig. 4, the auxiliary tamping device is similar to a boom of an excavator, and comprises a rotating base 10, a vertical arm 2 positioned on the rotating base 10, a transverse arm 3 hinged with the vertical arm, and a tamping arm 4 hinged with the transverse arm, wherein the end part of the tamping arm is hinged with a tamping pick assembly 13, and the vertical arm 2, the transverse arm 3 and the tamping arm 4 are respectively provided with a driving

oil cylinder

5, 6 and 7. The vertical arm 2 is used for controlling the rotation of the whole suspension arm, the transverse arm 3 is used for controlling the transverse movement of the auxiliary tamping device 1, and the tamping arm 4 is used for controlling the lifting and the downward insertion of the tamping device. In order to stabilize the boom, two support points 8, 9 are provided below the boom on the tamping vehicle.

In the process of tamping the line, only the main tamping device is needed to work, and the auxiliary tamping device 1 is in a locking state; in the tamping operation in the turnout area, the main tamping device is firstly adopted for operation, and under the condition that the transverse moving distance of the main tamping device is limited, the auxiliary tamping device 1 is unlocked to tamp the fourth far-end steel rail.

Fig. 5 and 6 show another embodiment provided by the invention, wherein the auxiliary tamping device 1 is a small tamping machine 11 which is arranged on a tamping vehicle, the engine of the small tamping machine 11 is an electric motor, and a power supply is provided from the tamping vehicle to drive the electric motor to work, and the small tamping machine is not mechanically connected with the tamping vehicle. Only the main tamping device is needed to work during the tamping operation of the line; in the tamping operation of the turnout area, the main tamping device is firstly adopted for operation, and under the condition that the transverse moving distance of the main tamping device is limited, the hoisting device 12 moves the small tamping machine 11 from the track tamping car to the turnout area to tamp the fourth far-end steel rail.
