Description

Technical Field

[0001] This invention relates to an adjustable gauge tracked railway sleeper changer, belonging to the field of engineering machinery technology. Background Technology

[0002] Railway track gauge refers to the distance between two steel rails. There are more than 30 different track gauges worldwide, categorized into standard gauge, broad gauge, and narrow gauge. China's railways mainly use standard gauge, with some regions using narrow gauge. India, Pakistan, Russia, and other countries primarily use broad gauge; Japan, Guinea, Cameroon, and other countries mainly use narrow gauge. In addition, some countries and regions construct double-gauge or multi-gauge railways on key sections to ensure the passage of trains of different gauges.

[0003] Existing self-propelled railway equipment has a dedicated railway walking system to ensure smooth travel along the railway. The direction of travel is restricted by the cooperation of 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. It can only be used for fixed track gauge. Once the track gauge is changed, it cannot be used normally, or a lot of manpower and time are required to replace the relevant structural components with bolts and pins before it can be used again.

[0040] like Figure 8As shown, the adjusting mechanism 4-11 includes a housing 4-11-1, a cylinder 4-11-18 is disposed inside the housing 4-11-1, and a first piston 4-11-6 and a second piston 4-11-5 are respectively located on both sides of the cylinder 4-11-18. The first piston 4-11-6 and the second piston 4-11-5 are slidably sealed to the inner wall of the housing 4-11-1, and the outer sides of the first piston 4-11-6 and the second piston 4-11-5 are respectively in contact with the inner sides of the first connecting shaft 4-9 and the second connecting shaft 4-13. The housing 4-11-1 has a first threaded hole 4-11-1-3 and a second threaded hole 4-11-1-4. The first threaded hole 4-11-1-3 and the second threaded hole 4-11-1-4 are respectively installed with a first connector 4-15 and a second connector 4-16. The reversing solenoid valve 9 has a total of 4 oil ports, including two oil inlets and two oil return ports. The first connector 4-15 and the second connector 4-16 are respectively connected to the oil inlet of the reversing solenoid valve, and are connected to the high-pressure oil port by default.

[0041] The reversing solenoid valve 9 is mounted on the travel bracket 4-7. A first annular groove 4-11-18-9 and a second annular groove 4-11-18-10 are formed on the cylinder body 4-11-18.

A first spring mounting groove 4-11-18-2 and a second spring mounting groove 4-11-18-4 are respectively provided on both sides of the cylinder body 4-11-18. One end of a spring 4-11-14 is connected to each of the first spring mounting groove 4-11-18-2 and the second spring mounting groove 4-11-18-4. The other ends of the two springs 4-11-14 are respectively connected to the inner ends of the first connecting shaft 4-9 and the second connecting shaft 4-13. Let the tension of the spring 4-11-14 be F, and the frictional force of the guide wheel assembly be G, requiring F > G. Figure 1In the middle position, with the track gauge at its minimum, this invention can inject high-pressure oil into the inner cavities of the first piston 4-11-6 and the second piston 4-11-5 via the reversing solenoid valve 9. This causes the first piston 4-11-6 and the second piston 4-11-5 to respectively drive the first connecting shaft 4-9 and the second connecting shaft 4-13 to move outward, thus increasing the track gauge. When a decrease in track gauge adjustment is required, the injection of high-pressure oil into the inner cavities of the first piston 4-11-6 and the second piston 4-11-5 is stopped via the reversing solenoid valve 9. Under the tension of the spring 4-11-14, the first connecting shaft 4-9 and the second connecting shaft 4-13 then move inward.

[0047] like Figure 13 , Figure 14 and Figure 15As shown, a first connecting shaft oil groove 4-9-5 is provided on the first force-bearing part 4-9-3, and a retaining ring 4-11-3 and an O-ring 4-11-4 are provided in the first connecting shaft oil groove 4-9-5.

[0048] like Figure 16 As shown, the adjustment process of this invention is as follows: Using the forward direction as a reference, three track gauge modes are set in the system (controller): L1, L2, and L3. Before adjustment, the guide travel system is first lifted off the rail using a hydraulic cylinder, and the limit bolts in the guide travel system are removed. Then, one mode Li is selected, and the currently used track gauge Lx is manually input. The value of Li-Lx is judged. If Li-Lx is negative, it indicates that the current track gauge is less than the required track gauge. At this time, high-pressure oil causes the first piston to move to the right and the second piston to move to the left through the reversing solenoid valve, stretching the spring. The first guide wheel assembly moves to the right, and the second guide wheel assembly moves to the left. 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 module. If Lx + (X1 + X2)... If Li - Lx is positive, the first and second pistons stop moving, and the first and second guide wheel assemblies also stop moving. If Li - Lx is positive, it means that the initial track gauge is greater than the required track gauge. In this case, the reversing solenoid valve is changed so that the high-pressure oil from the first and second joints of the first and second pistons returns to the oil tank through the reversing solenoid valve. At the same time, the spring resets, causing the first piston to move to the left and the second piston to move to the right. The first guide wheel assembly moves to the left and the second guide wheel assembly moves to the right. 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 module. If Lx - (X1 + X2) ≥ Li, the first and second pistons stop moving, and the first and second guide wheel assemblies stop moving. When the adjustment is complete, the limit bolts are installed, and the guide walking system is placed on the rail using the hydraulic cylinder for subsequent normal operation.

[0049] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
