Description

Technical Field

[0001] The utility model belongs to the technical field of self-moving trains, and particularly relates to a jacking and deviation-correcting mechanism and a self-moving train. Background Art

[0002] When a hydraulic self-propelled trackless equipment train for mining is running in the tunnel of a fully mechanized mining face in a coal mine, it may automatically deviate. To this end, a utility model patent with patent application number 202220927414.9 discloses a vehicle head deviation adjustment device, comprising a connecting seat, a telescopic cylinder and a support seat, one end of the telescopic cylinder being hinged to the connecting seat, and the other end of the telescopic cylinder being fixedly connected or hinged to the support seat. A limiter is provided on the connecting seat, which can limit the rotation of the telescopic cylinder relative to the connecting seat. The connecting seat is connected to the existing vehicle body, and the telescopic cylinder is rotated to make it face one side of the tunnel. The telescopic cylinder is extended to make the support seat and one side of the tunnel contact each other, and as the telescopic cylinder is extended, the vehicle body is pushed to move to the other side of the tunnel, thereby achieving deviation adjustment.

[0003] It only corrects deviations and is equipped with two stop pins to keep the telescopic cylinder upright, preventing it from deviating to one side and affecting passability. Therefore, this structure has a relatively simple function; when correction is not required, it does not serve any other purpose. Utility Model Content

[0004] In response to the above technical problems, the present invention provides a jacking and deviation-correcting mechanism on one hand, which has two functions of jacking and deviation-correcting; another purpose of the present invention is to provide a self-moving train including the above-mentioned jacking and deviation-correcting mechanism.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A lifting and correcting mechanism comprises a mounting base, a support rail, and a correcting oil cylinder; the support rail is slidably connected to the mounting base; a pair of connecting bases are slidably connected to the mounting base, the mounting base is located between the pair of connecting bases, and each connecting base is connected to a support leg via a telescopic oil cylinder; the mounting base and the pair of connecting bases are each provided with a connecting ear hinged to the correcting oil cylinder; connecting holes are provided at both ends of the support rail, and the connecting bases and the connecting holes are connected via a latch;

[0007] When the two ends of the correcting oil cylinder are respectively hinged to the connecting ears on a pair of connecting seats, the correcting oil cylinder retracts to clamp the pair of connecting seats to the mounting seat; when the pair of connecting seats are respectively plugged into the corresponding connecting holes through pins, the two ends of the correcting oil cylinder are respectively hinged to the mounting seat and the connecting ears on one of the connecting seats.

[0008] The support leg is hinged to the end of the telescopic oil cylinder; the other end of the telescopic oil cylinder is fixedly connected to the connecting seat.

[0009] The mounting seat is provided with a connecting groove and a supporting pin which are slidably connected to the supporting rail; the supporting pin is fixedly connected to the mounting seat.

[0010] A first wedge block is fixed in each of the pair of connecting seats; a corresponding second wedge block is provided on the support track; and the movement of the support track can be restricted by the cooperation between the first wedge block and the corresponding second wedge block.

[0011] A self-moving train set includes a self-moving car body, a self-moving track, and a jacking and correcting mechanism. The self-moving car bodies are provided in plurality and are connected by connecting rods. A through groove is provided at the bottom of the self-moving car body to cooperate with the self-moving track. The self-moving track is located in the through groove. A driving cylinder is hinged between the self-moving car body and the self-moving track. A jacking mechanism is provided at one end of the self-moving car body, and the other end of the self-moving car body is fixedly connected to a mounting seat in the jacking and correcting mechanism.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] When both ends of the correction cylinder are hinged to the connecting ears on a pair of connecting seats, the correction cylinder retracts, causing the pair of connecting seats to clamp the mounting seat, thus limiting the position change of the two connecting seats. In this position, the telescopic cylinder extends to lift the self-propelled vehicle body, preventing one end of the self-propelled vehicle body from rubbing against the ground, thus achieving the function of lifting the bottom.

[0017] When a pair of connecting seats are respectively plugged into the corresponding connecting holes through pins, the two ends of the correcting oil cylinder are respectively hinged to the mounting seat and the connecting ears on one of the connecting seats; in this state, the correcting operation can be performed by extending the correcting oil cylinder, that is, it can play a correcting role.

[0018] The above-mentioned structural setting can not only play the role of lifting the bottom to facilitate self-movement, but also play the role of correcting the deviation, thereby avoiding the situation of being "useless" when no correction is needed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] 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.

[0035] Example 1

[0036] like Figure 1-7 The figure shows a lifting and correcting mechanism, comprising a mounting base 10, a support rail 11, and a correcting cylinder 12. The support rail 11 is slidably connected to the mounting base 10. A pair of connecting bases 13 are slidably connected to the mounting base 10, with the mounting base 10 positioned between the pair of connecting bases 13. Each connecting base 13 is connected to a support leg 15 via a telescopic cylinder 14. Both the mounting base 10 and the pair of connecting bases 13 are provided with connecting ears 16 hingedly connected to the correcting cylinder 12. Connecting holes 17 are provided at both ends of the support rail 11. The connecting bases 13 (with corresponding through holes) are connected to the connecting holes 17 via a latch 18. The correcting cylinder 12 can be hinged to different connecting ears 16 at each end to achieve different functions as needed.

[0037] Function 1. Lifting and bottom lifting: Currently, self-moving trains mainly adopt the setting of a bottom lifting mechanism at one end. When one end is lifted up, the self-moving body 20 of the self-moving train is in an inclined state, and the other end moves by friction with the ground.

[0038] When the two ends of the correcting cylinder 12 are hinged to the connecting ears 16 on the pair of connecting seats 13, the correcting cylinder 12 retracts, causing the pair of connecting seats 13 to clamp the mounting base 10. After clamping, the two supporting legs 15 are positioned above the self-propelled track 21. The telescopic cylinder 14 can be extended to bring the supporting legs 15 into contact with the self-propelled track 21, thereby lifting the other end of the self-propelled vehicle body 20, thereby preventing the other end from rubbing against the ground. Moreover, the surface of the self-propelled track 21 is smoother than the ground, resulting in less friction and preventing damage to the ground.

[0039] Function 2: Correction

[0040] When the pair of connection seats 13 are respectively connected to the corresponding connection holes 17 through the pins 18 , the pair of connection seats 13 and the support rails 11 form a whole; and the connection seats 13 are located outside the self-propelled vehicle body 20 .

[0041] One end of the correcting cylinder 12 is hinged to the connecting lug 16 on the mounting base 10; the other end of the correcting cylinder 12 is hinged to the connecting lug 16 on the left connecting base 13. Then, the telescopic cylinder 14 is extended to bring the support leg 15 into contact with the ground. This extension of the correcting cylinder 12 pushes the other end of the self-propelled vehicle 20 to the right, completing the correcting operation. Conversely, the other end of the correcting cylinder 12 is hinged to the connecting lug 16 on the right connecting base 13. Then, the telescopic cylinder 14 is extended to bring the support leg 15 into contact with the ground. This extension of the correcting cylinder 12 pushes the other end of the self-propelled vehicle 20 to the left.

[0042] Furthermore, the support leg 15 is hinged to the end (lower end) of the telescopic cylinder 14 , and the other end (upper end) of the telescopic cylinder 14 is fixedly connected to the connecting seat 13 .

[0043] Furthermore, various structures can be used to achieve the sliding connection between the mounting base 10 and the support rail 11. For example, the mounting base 10 can be provided with a connecting groove 19 that is slidably connected to the support rail 11 and a support pin 110. The support pin 110 is fixedly connected to the mounting base 10. A connecting slide groove that cooperates with the support rail 11 is formed between the connecting groove 19 and the support pin 110.

[0044] Furthermore, in order to prevent the support rail 11 from moving randomly during the jacking and bottom lifting process, a first wedge block 111 is fixed in each of the pair of connecting seats 13 ; and a corresponding second wedge block 112 is provided on the support rail 11 .

[0045] When the two ends of the correction cylinder 12 are respectively hinged to the connecting ears 16 on the pair of connecting seats 13, the correction cylinder 12 retracts, causing the pair of connecting seats 13 to clamp the mounting seat 10. At the same time, the first wedge block 111 contacts the corresponding second wedge block 112, thereby limiting the movement of the support rail 11.

[0046] Example 2

[0047] This embodiment provides a self-propelled train including the structure of the embodiment 1 on the basis of the embodiment 1. Figure 8-13 As shown, it includes a self-moving body 20, a self-moving track 21 and a jacking and correcting mechanism 1. There are several self-moving bodies 20, which are connected by a connecting rod 22. The two ends of the connecting rod 22 are respectively hinged to the adjacent self-moving bodies 20; the bottom of the self-moving body 20 is provided with a through groove 23 that cooperates with the self-moving track 21, and the self-moving track 21 is located in the through groove 23 (there is a gap between the two in the longitudinal direction to ensure that the self-moving track 21 can move forward after the bottom of the self-moving body 20 contacts the ground), and a driving cylinder 24 is hinged between the self-moving body 20 and the self-moving track 21; one end of the self-moving body 20 is provided with a jacking mechanism 25, and the other end of the self-moving body 20 is fixedly connected to the mounting seat 10 in the jacking and correcting mechanism 1.

[0048] During self-movement, the two ends of the correcting cylinder 12 are respectively hinged to the connecting ears 16 on a pair of connecting seats 13. By retracting the correcting cylinder 12, the pair of connecting seats 13 clamp the mounting seat 10; at this time, the support legs 15 are located above the self-moving track 21 and can be slidably connected to the self-moving track 21.

[0049] The self-migration process is as follows:

[0050] The self-propelled vehicle 20 moves: The lifting mechanism 25 lifts one end of the self-propelled vehicle 20, and the telescopic cylinder 14 extends to make the support leg 15 contact the self-propelled track 21, thereby lifting the other end of the self-propelled vehicle 20. The extension of the driving cylinder 24 pushes the self-propelled vehicle 20 along the self-propelled track 21.

[0051] Track movement: After the self-propelled vehicle body 20 moves, the jacking mechanism 25 and the telescopic cylinder 14 retract so that the self-propelled vehicle body 20 contacts the ground; the self-propelled track 21 moves forward by retracting the driving cylinder 24.

[0052] The self-moving vehicle body 20 and the self-moving track 21 migrate alternately, thereby achieving overall self-movement.

[0053] When correction is required, the pair of connecting blocks 13 are first moved to the ends of the support rail 11 and connected with the latch 18, so that the pair of connecting blocks 13 and the support rail 11 form a single unit, with the connecting blocks 13 positioned outside the self-propelled vehicle 20. Next, one end of the correction cylinder 12 is hinged to the connecting lug 16 on the mounting block 10; the other end of the correction cylinder 12 is hinged to the connecting lug 16 on the left / right side of the connecting block 13. Finally, the telescopic cylinder 14 is extended to bring the support legs 15 into contact with the ground. This extension of the correction cylinder 12 pushes the other end of the self-propelled vehicle 20 to the right / left, completing the correction.

[0054] Furthermore, in order to reduce the friction between the support legs 15 and the self-moving track 21 , a slide plate 26 is fixedly connected to the self-moving track 21 and is slidably connected to the support legs 15 ; the slide plate 26 is preferably made of a polytetrafluoroethylene plate.

[0055] Furthermore, the lifting mechanism 25 can be constructed using a conventional structure and specifically includes a lifting cylinder 27 and a support base 28. The two ends of the lifting cylinder 27 are hingedly connected to the self-propelled vehicle body 20 and the support base 28, respectively. A support wheel 29 is rotatably connected to the support base 28, and the support wheel 29 contacts the self-propelled track 21. The lifting cylinder 27 is extended to allow the support wheel 29 to contact the self-propelled track 21, thereby lifting one end of the self-propelled vehicle body 20.

[0056] 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.
