Detailed Implementation The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1, as Figures 1-7 As shown, this embodiment proposes a side-mounted pneumatic lifting vehicle for installing underground pipelines in mines, including a trackless rubber-tired vehicle 1, a mounting plate 2 on the trackless rubber-tired vehicle 1, and also including: a mounting shaft 3, a movable frame 5, a plug bracket 6, a side-mounted lifting mechanism, a retraction mechanism and a steering mechanism. The mounting shaft 3 is rotatably mounted on the mounting plate 2, and a mounting sleeve 4 is sleeved on the mounting shaft 3. The movable frame 5 is slidably mounted on the mounting sleeve 4. Two plug brackets 6 are provided and are mounted on the movable frame 5. The side-mounted lifting mechanism is mounted on the movable frame 5. The side-mounted lifting mechanism includes a lifting frame 7, which is mounted on the movable frame 5. A support frame 6 is mounted on the lifting frame 7 to lift the height of the support frame 6. The side-mounted lifting mechanism also includes a lifting frame 8, a lifting frame 9, a slide frame 10, a pulley block 11, and a pneumatic winch 13. The lifting frame 8 is fixedly mounted on the movable frame 5. The lifting frame 7 is slidably mounted inside the lifting frame 8. The lifting frame 9 is slidably mounted inside the lifting frame 7. There are two slide frames 10, which are slidably mounted on the lifting frame 9. The support frame 6 is mounted on the slide frame 10. There are multiple pulley blocks 11, which are respectively mounted on the lifting frame 8, the lifting frame 7, and the lifting frame 9. A steel wire rope 12 is installed between the multiple pulley blocks 11 for transmission. The pneumatic winch 13 is mounted on the mounting frame 4, and the steel wire rope 12 is wound around the pneumatic winch 13. The steel wire rope 12 is wound into the pneumatic winch 13 installed on the mounting frame 4 by rotating it. When the steel wire rope 12 moves, it is supported and driven by the pulley block 11, thereby driving the lifting frame 9 to rise and fall in the lifting frame 7. The lifting frame 7 rises and falls in the lifting frame 8, thereby driving the insertion frame 6 to lift.

[0018] A retraction mechanism is installed on the insert 6 to retract the insert 6. The retraction mechanism includes: a slider 14, a pull rod 15, a connecting rod 16, a connecting rod 2 17, and a first electric cylinder 18. The slider 14 is slidably installed in the slide 10. The pull rod 15 is rotatably installed between the slider 14 and the insert 6. The connecting rod 16 is rotatably installed between the slide 10 and the insert 6. The connecting rod 2 17 is rotatably installed between the slide 10 and the pull rod 15. The first electric cylinder 18 is installed on the slide 10. The slider 14 is fixedly installed at the output end of the first electric cylinder 18. When the insert frame 6 needs to be retracted, the first electric cylinder 18 on the lifting frame 9 drives the slider 14 to rise within the slide 10, thereby driving the pull rod 15 rotatably connected to the slider 14 to rise, which in turn drives the insert frame 6 to flip upward through the pull rod 15. When the insert frame 6 flips, the connecting rod 16 and connecting rod 17 rotatably connected to the slide 10 support the pull rod 15 and the insert rod, thereby retracting the insert rod, reducing the space occupied by the insert frame 6, and increasing the shunting space when the trackless rubber-wheeled vehicle 1 moves.

[0019] The steering mechanism is mounted on the mounting bracket 4 and is used to drive the insert 6 to turn. The steering mechanism includes a rotating gear 19, a first motor 20 and a drive gear 21. The rotating gear 19 is fixedly mounted on the mounting shaft 3, the first motor 20 is mounted on the mounting bracket 4, and the drive gear 21 is fixedly mounted on the output end of the first motor 20. The drive gear 21 meshes with the rotating gear 19.

[0020] When it is necessary to rotate the side-mounted lifting mechanism, the first motor 20 installed on the mounting bracket 4 drives the drive gear 21 and the rotating gear 19 to rotate, thereby driving the mounting bracket 4 to rotate on the mounting shaft 3, which in turn drives the side-mounted lifting mechanism to rotate, thus enabling the side-mounted lifting mechanism to rotate from one side of the trackless rubber-wheeled vehicle 1 to the other side.

[0021] The movable frame 5 is equipped with a moving mechanism, which includes a moving toothed belt 22, a second motor 23 and a moving gear 24. The moving toothed belt 22 is fixedly mounted on the movable frame 5, the second motor 23 is mounted on the mounting sleeve 4, and the moving gear 24 is fixedly mounted on the output end of the second motor 23. The moving gear 24 meshes with the moving toothed belt 22.

[0022] When the movable frame 5 needs to move on the mounting frame 4, the second motor 23 installed on the mounting frame 4 rotates, thereby driving the movable gear 24 to drive the movable toothed belt 22 fixedly installed on the movable frame 5 to move, and thus driving the movable frame 5 to move on the mounting frame 4.

[0023] The lifting frame 9 is equipped with a bidirectional adjustment mechanism, which includes a bidirectional screw 25 and a third motor 26. The bidirectional screw 25 is rotatably mounted inside the lifting frame 9. The slide 10 has a screw hole and is threadedly connected to the bidirectional screw 25. The third motor 26 is mounted on the lifting frame 9. The output end of the third motor 26 passes through the lifting frame 9 and is fixedly connected to the bidirectional screw 25.

[0024] The third motor 26 installed on the lifting frame 9 drives the bidirectional screw 25 to rotate, thereby adjusting the distance between the two slides 10.

[0025] The lifting frame 8 is equipped with a support mechanism, which includes a support rod 27, a support plate 28, and a second electric cylinder 29. The support rod 27 is slidably mounted on the lifting frame 8, the support plate 28 is fixedly mounted on the support rod 27, and the second electric cylinder 29 is mounted on the lifting frame 8. The support rod 27 is fixedly mounted on the output end of the second electric cylinder 29.

[0026] When the support frame 6 is raised, the second electric cylinder 29 installed on the lifting frame 8 drives the support rod 27 to descend, and the support plate 28 fixedly installed on the support rod 27 supports the lifting frame 8, which increases the safety of the side-mounted lifting mechanism and is also suitable for roadways with uneven ground.

[0027] A fixed frame 30 is fixedly installed on the mobile frame 5, and a lifting ring 31 is fixedly installed on the fixed frame 30, so that after the side-mounted lifting mechanism is disassembled from the trackless rubber-wheeled vehicle 1, the side-mounted lifting mechanism can be lifted by an external crane through the lifting ring 31.

[0028] In this embodiment, when installing underground pipelines in a mine, the mounting shaft 3 is first installed on the trackless rubber-tired vehicle 1 via the mounting plate 2. Then, the mounting sleeve 4 is fitted onto the mounting shaft 3. The installation does not place high demands on the trackless rubber-tired vehicle 1, requires no major modifications, does not affect the normal load-bearing use of the trackless rubber-tired vehicle 1, and is easy and quick to dismantle. It is applicable to various models of trackless rubber-tired vehicles 1. The side-mounted lifting mechanism can be adjusted to either side of the trackless rubber-tired vehicle 1. After dismantling, the trackless rubber-tired vehicle 1 can be used normally. Then, the first motor 20 installed on the mounting sleeve 4 drives the drive gear. The wheel 21 rotates with the rotating gear 19, thereby driving the mounting sleeve 4 to rotate on the mounting shaft 3, which in turn drives the side-mounted lifting mechanism to rotate, thus enabling the side-mounted lifting mechanism to rotate from one side of the trackless rubber-wheeled vehicle 1 to the other side, thereby rotating the side-mounted lifting mechanism to the side where it needs to work. Then, the second motor 23 set on the mounting sleeve 4 rotates, thereby driving the moving gear 24 to drive the moving toothed belt 22 fixedly set on the moving frame 5 to move, thereby driving the moving frame 5 to move on the mounting sleeve 4, and thus moving the insert 6 to the position where it needs to be used.

[0029] Furthermore, after the insert frame 6 moves to the designated position, the second electric cylinder 29 on the lifting frame 8 drives the support rod 27 to descend, and the support plate 28 fixed on the support rod 27 supports the lifting frame 8, increasing the safety of the side-mounted lifting mechanism. It is also suitable for roadways with uneven ground. Then, the pneumatic winch 13 on the installation sleeve 4 rotates, thereby winding the wire rope 12 into the pneumatic winch 13. When the wire rope 12 moves, it is supported and transmitted through the pulley group 11, thereby driving the lifting frame 9 to rise and fall within the lifting frame 7. The lifting frame 7 rises and falls within the lifting frame 8, thereby driving the insert frame 6 to perform lifting work. After the pipeline installation on one side of the mine is completed, the first motor 20 on the installation sleeve 4 drives the drive gear 21 and the rotating gear 19 to rotate, thereby driving the installation sleeve 4 to rotate on the installation shaft 3, and then driving the side-mounted lifting mechanism to rotate, thereby enabling the side-mounted lifting mechanism to rotate from one side of the trackless rubber-wheeled vehicle 1 to the other side where construction needs to be carried out.

[0030] After the lifting work is completed, when the trackless rubber-wheeled vehicle 1 needs to be moved, the first electric cylinder 18 set on the lifting frame 9 drives the slider 14 to rise in the slide 10, thereby driving the pull rod 15 rotatably connected on the slider 14 to rise, thereby driving the insert frame 6 to flip upward through the pull rod 15. When the insert frame 6 flips, the connecting rod 16 and connecting rod 2 rotatably connected on the slide 10 support the pull rod 15 and the insert rod, thereby retracting the insert rod, reducing the space occupied by the insert frame 6, and increasing the shunting space when the trackless rubber-wheeled vehicle 1 is moved.

[0031] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
