Background Art

[0002] In the production operation of coal yards, it is often necessary to transport coal blocks out of the mine. However, the mines where the coal is usually transported are relatively narrow. Due to limited space, it is not suitable for truck transportation. Therefore, rail cars are needed for transportation. However, it is difficult for rail cars to turn in a narrow space, and they often derail when turning. Therefore, automatic track-changing and anti-dropping guide rails are needed to solve this problem.

DETAILED DESCRIPTION

[0021] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] like Figure 1-Figure 3 As shown, the guide rail for automatic track changing and preventing derailment provided by the present embodiment comprises two main rails 1, an auxiliary turning rail 2 is arranged between the two main rails 1, a retractable straight-moving structure 3 is arranged at the connection between the two main rails 1 and the auxiliary turning rail 2, the retractable straight-moving structure 3 comprises a first hydraulic rod 4 and a first limiting rail 5 arranged at the telescopic end of the first hydraulic rod 4, two turning extension rails 6 are arranged through the outer side of one of the main rails 1, a retractable track-changing turning limiting structure 7 is arranged at the connection between the two turning extension rails 6 and the main rail 1, the retractable track-changing turning limiting structure 7 comprises a second hydraulic rod 8 and a second limiting rail 9 arranged at the telescopic end of the second hydraulic rod 8, the auxiliary turning rail 2 can guide and limit the changing direction of the inner card-embedded wheel hub 17, when the retractable straight-moving structure 3 retracts downward, the retractable track-changing turning limiting structure 7 does not move, so the straight-moving structure can be kept on the unchanged track, and when the retractable straight-moving structure 3 returns to the initial position, the retractable track-changing turning limiting structure 7 retracts downward, so the track can be changed.

[0023] First limit sliders 10 are provided on both sides of the first limit rail 5, and second limit sliders 11 are provided on both sides of the second limit rail 9. The first limit rail 5 can limit the internal embedded wheel hub 17 of the track change, and the second limit rail 9 can limit the internal embedded wheel hub 17 of the track change for straight travel. The first limit slider 10 performs sliding limit on the first limit rail 5, and the second limit slider 11 performs sliding limit on the second limit rail 9.

[0024] The two main rails 1 and the auxiliary turning rail 2 are provided with a first slide groove 12 adapted to the first limit slider 10 , and the two turning extension rails 6 and the intersecting main rails 1 are provided with a second slide groove 13 adapted to the second limit slider 11 .

[0025] Metal cover plates 14 which are in the same horizontal plane as the track are provided at the openings on the upper surfaces of the first chute 12 and the second chute 13 to prevent bumps during transportation caused by the gaps in the chute.

[0026] Pressure relief pillows 15 are provided below the two main rails 1 , the auxiliary turning rails 2 and the two turning extension rails 6 to increase the contact area and reduce the pressure.

[0027] A support for a fixed work platform 16 is provided below the first hydraulic rod 4 and the second hydraulic rod 8 . The support for the fixed work platform 16 is used to support and fix the telescopic straight-moving structure 3 and the telescopic track-changing and turning limiting structure 7 .

[0028] An inner-embedded wheel hub 17 is provided at one end of the upper surface of the two main rails 1. The inner-embedded wheel hub 17 is less likely to derail during movement. The wheel rim 18 on the inner side of the inner-embedded wheel hub 17 has the same width as the first limiting rail 5 and the second limiting rail 9, which facilitates the limiting of the inner-embedded wheel hub 17 in the track change section.

[0029] like Figure 1-Figure 3 As shown, the principle of the automatic track-changing and anti-dropping guide rail provided in this embodiment is as follows: when the transport vehicle travels to the road section and needs to go straight, the device will control the first hydraulic rod 4 on the supporting fixed workbench 16 to retract, so that the first limit rail 5 moves downward, and the retractable track-changing and turning limit structure 7 remains unchanged at the initial position, so that the transport vehicle goes straight through the road section, and then the first limit rail 5 will return to the initial position under the action of the first hydraulic rod 4;

[0030] When the transport vehicle needs to change tracks when traveling to this section, the device will control the retraction of the second hydraulic rod 8 on the supporting fixed workbench 16, so that the second limit rail 9 moves downward, while the retractable straight-moving structure 3 remains in the initial position unchanged, so that the transport vehicle can go straight through the section, and then the second limit rail 9 will return to the initial position under the action of the second hydraulic rod 8.

[0031] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0032] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0033] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
