[0002] Self-moving trains, particularly those used underground in coal mines, are intelligent transportation tools used in fully mechanized coal mining operations. These trains utilize hydraulic systems or rail-guided assemblies to achieve autonomous movement, replacing traditional winch traction methods and significantly improving the safety and efficiency of coal mine transportation.

[0003] For example, patent application number 202021163044.3 discloses a self-propelled train in which the ends of the support shoe are connected to the frame via cranks, forming a parallelogram mechanism. The ends of the telescopic cylinder are hinged to the frame and the support shoe, respectively, and the support and bottom lifting are achieved by the extension and contraction of the telescopic cylinder. The use of a connecting rod drive method can simplify the overall structure and reduce the use of oil cylinders.

[0004] The train in the prior art is usually arranged side by side with the belt conveyor in the well, which is suitable for use in a wide well. However, for some wells with high height but narrow width, it is impossible to arrange them side by side or the movement space is extremely small after the side by side arrangement.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1

[0026] like Figure 1-3 As shown, a straddle-type train includes a straddle-type train body 1 and a bottom-lifting mechanism 2. The straddle-type train body 1 is an "N"-shaped structure with a passage 3 for mining equipment 12. After arrangement, a vertical arrangement can be formed between the straddle-type train body 1 and the mining equipment 12, which can effectively utilize the vertical space underground and reduce the width requirement.

[0027] There are two bottom lifting mechanisms 2, which are respectively arranged on both sides of the straddle body 1; the bottom lifting mechanism 2 includes a supporting slipper 4 and a bottom lifting telescopic cylinder 5, the supporting slipper 4 is connected to the upper part of the straddle body 1 through a pair of connecting rods 23, and the two ends of the connecting rod 23 are respectively hinged to the upper part of the straddle body 1 and the supporting slipper 4, and the two ends of the bottom lifting telescopic cylinder 5 are respectively hinged to the upper part of the straddle body 1 and the supporting slipper 4.

[0028] The bottom of the straddle vehicle body 1 is connected to the track 7 through a track lifter 6 ; a traction cylinder 8 is provided between the bottom of the straddle vehicle body 1 and the track 7 ; a pulley 22 is provided at the bottom of the straddle vehicle body 1 , and the pulley 22 is in contact with the track 7 .

[0029] During self-propelled movement, the telescopic cylinder 5 extends, rotating the pair of connecting rods 23 and bringing the support shoe 4 into contact with the ground. The traction cylinder 8 then retracts, moving the track 7 forward. The telescopic cylinder 5 then retracts, rotating the pair of connecting rods 23 in the opposite direction, freeing the support shoe 4 from contact with the ground and supporting it on the track 7. Finally, the traction cylinder 8 extends, driving the straddle body 1 forward along the track 7. Repeating these steps allows the train to self-propelled.

[0030] Furthermore, the straddle vehicle body 1 includes a roof 9 and a bottom plate 10. There are two bottom plates 10, and there is a gap between the two bottom plates 10. The two bottom plates 10 are fixedly connected to the roof 9 through columns 11 respectively, and the two ends of the columns 11 are fixedly connected to the bottom plate 10 and the roof 9 respectively; the track lifting device 6 is specifically arranged at the bottom of the column 11 or on the bottom plate 10.

[0031] In order to prevent unnecessary friction between the straddle vehicle body 1 and the mining equipment 12 (such as a belt conveyor) during the self-movement process, this embodiment adds a support roller assembly 13 on the basis of the embodiment 1.

[0032] Example 2

[0033] like Figure 4-7 As shown, the support roller assembly 13 includes a support frame 14 and support rollers 15. The support frame 14 is fixedly or slidably connected to the straddle vehicle body 1, and the support rollers 15 are rotatably connected to the support frame 14. The support rollers 15 are located inside the straddle vehicle body 1. Four support roller assemblies 13 are preferably provided, two on each side of the straddle vehicle body 1.

[0034] During the self-propelled movement, the vehicle may deviate left or right. When this occurs, the inner side of the straddle vehicle body 1 approaches the mining equipment 12, and the frame of the mining equipment 12 contacts the support rollers 15, which are rotatable. This prevents friction between the two. Of course, during design, a gap should be left as wide as possible between the width of the passage 3 of the straddle vehicle body 1 and the mining equipment 12, depending on the width of the underground mine.

[0035] Furthermore, since the straddle body 1 will not only move forward but also move up and down during the self-movement process, a rotating shaft 16 connected to the support roller 15 is provided on the support frame 14. The rotating shaft 16 is fixedly connected to the support frame 14, and the support roller 15 is rotatably connected to the rotating shaft 16 and can slide axially along the rotating shaft 16. A pair of springs 17 are sleeved on the rotating shaft 16, and the support roller 15 is located between the pair of springs 17.

[0036] When the straddle vehicle body 1 moves up and down, the support rollers 15 can move up and down along the rotating shaft 16, thereby preventing friction between the support rollers 15 and the mining equipment 12. A pair of springs 17 are also provided. When the support rollers 15 move up and down, the corresponding springs 17 are compressed. When the support rollers 15 deviate again, causing them to lose contact with the mining equipment 12, the compressed springs 17 release their elastic potential energy, causing the support rollers 15 to return to their original position.

[0037] Furthermore, a pair of gaskets 18 are sleeved on the rotating shaft 16 , and each gasket 18 is located between the spring 17 and the support roller 15 ; that is, the spring 17 is in contact with the support roller 15 through the gasket 18 .

[0038] Furthermore, in order to avoid hard contact between the support roller 15 and the mining equipment 12 after left and right deviation occurs during operation, the following structure is preferably adopted:

[0039] The support frame 14 is slidably connected to the straddle body 1, with a spring assembly disposed between the two. The spring assembly includes a guide rod 19 and a second spring 20. One end of the guide rod 19 passes through the straddle body 1 and is fixedly connected to the support frame 14. The other end of the guide rod 19 is provided with a stopper 21. The second spring 20 is sleeved over the guide rod 19, with its ends respectively contacting the support frame 14 and the straddle body 1. The arrangement of the spring assembly allows the support frame 14 and the support roller 15 to move left and right, preventing hard contact between the support roller 15 and the mining equipment 12, thereby achieving elastic contact.

[0040] Only the preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the above embodiments.
