Description

Technical Field

[0001] The invention relates to a track-type railway sleeper changing machine capable of adjusting track gauge, and belongs to the technical field of engineering machinery. Background Art

[0002] Railway gauge refers to the distance between two rails. There are more than 30 types of gauges in the world, which are divided into three categories: standard gauge, wide gauge, and narrow gauge. China's railways mainly use standard gauge, and railways in some regions use narrow gauge; India, Pakistan, Russia and other countries mainly use wide gauge; Japan, Guinea, Cameroon and other countries mainly use narrow gauge; in addition, in order to ensure that trains of different gauges can pass, some countries and regions will build double-gauge railways or multi-gauge railways in key sections.

[0003] The existing railway-specific equipment with self-propelled function has a special railway travel system in order to be able to travel smoothly along the railway. The travel direction of the vehicle is limited by the cooperation of the guide wheels on both sides and the rails. The spacing of the guide wheels needs to be customized according to the track gauge of the construction site, and can only be applied to fixed track gauges. Once the track gauge changes, it cannot be used normally, or a lot of manpower and time are required to replace the relevant structural parts through bolts and pins before it can be restored to use.

If Li-Lx is a negative value, it means that the current track gauge is smaller than the required track gauge. At this time, the high-pressure oil moves the first piston to the right and the second piston to the left through the reversing solenoid valve, so that the spring is stretched, the first guide wheel assembly moves to the right and the second guide wheel assembly moves to the left, and the sensor detects the displacement X1 of the first guide wheel assembly and the displacement X2 of the second guide wheel assembly 14 through the annular detection module. If Lx+(X1+X2) ≥Li, the first piston and the second piston stop moving, and the first guide wheel assembly and the second guide wheel assembly also stop moving; if Li-Lx is a positive value, it means that the current track gauge is greater than the required track gauge, then the reversing solenoid valve is changed to make the high-pressure oil of the first joint and the second joint of the first piston and the second piston return to the oil tank through the reversing solenoid valve respectively, and the spring is reset at the same time, so that the first piston moves to the left and the second piston moves to the right, the first guide wheel assembly moves to the left and the second guide wheel assembly moves to the right, and the sensor detects the displacement X1 of the first guide wheel assembly and the displacement X2 of the second guide wheel assembly through the annular detection mold, Lx-(X1+X2) ≥Li, then the first piston and the second piston stop moving, and the first guide wheel assembly and the second guide wheel assembly stop moving. When the adjustment is completed, install the limit bolts, use the oil cylinder to put the guide travel system on the rail, and proceed normally.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
