[0002] In the underground coal mine, the drift tunnels of the fully mechanized mining working face are narrow and the ground is undulating. It is impossible to lay rails in the main and auxiliary drift tunnels. Therefore, the traditional wire rope traction equipment train will not be able to be realized when there are no tracks. If climbing tracks are used, it will be a waste of manpower and material resources. The use of rubber-wheeled flatbed carts has disadvantages such as too high center, limited load capacity, and difficult braking, which has caused great difficulties in the transportation of equipment underground and has become a bottleneck in production.

[0003] At present, the equipment train is a transportation equipment in the comprehensive mechanized coal mining system. It is installed in the main tunnel or auxiliary tunnel of the coal mining face. In the mine production process, in order to meet the normal production requirements of the comprehensive mining face, the equipment train needs to be pulled and moved as the comprehensive mining face advances in normal production. However, most traditional equipment trains use winch wire to pull the equipment train. This method can easily cause the equipment train to run away from the track, posing a major safety hazard.

[0039] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0040] Example 1

[0041] Please combine Figures 1 to 10 The slide rail type self-propelled train includes a main structure frame 1, a vehicle panel 2 supported on the top of the main structure frame 1 for carrying objects, and a self-driving device arranged on the main structure frame 1. The main structure frame 1 in this embodiment can be a vehicle body structural frame formed by resist welding of rectangular square tubes. The vehicle panel 2 can be installed on the main structure frame 1 by bolts to carry objects to be transported.

[0042] The self-driving device includes a slide rail 4, a combined slider 6, a propulsion stroke hydraulic cylinder 3 and a lifting mechanism. The slide rail 4 is fixed to the bottom of the structural main frame 1 and is parallel to the travel direction of the structural main frame 1. The combined slider 6 is accommodated in the slide rail 4 and can move relative to the slide rail 4. The propulsion stroke hydraulic cylinder 3 is fixed to the bottom of the structural main frame 1, and the output end is fixed to one side of the combined slider 6 to drive the combined slider.

[0043] The combined slide block 6 in this embodiment is a column with a quadrilateral cross section and a rectangular shape as a whole, and its bottom is a contact surface that contacts the ground in the travel direction. An anti-skid rubber pad can be arranged on its contact surface to increase the static friction between it and the ground, so that the slide rail type equipment self-moving train moves more smoothly.

[0044] The lifting mechanism is arranged on the side of the main structure frame 1, and is used for lifting the combined slider 6 to a suspended state relative to the ground when the main structure frame 1 is not moving, so as to facilitate the thrust stroke hydraulic cylinder 3 to reversely drive the combined slider 6 to move and reset, so as to prepare for the next movement of the slide rail equipment self-moving train, that is, after one movement is completed, the combined slider 6 is lifted and reset in the air, and when it needs to be moved again, the combined slider 6 is lifted and falls to contact the ground for thrust movement.

[0045] When the bottom of the combined slider 6 touches the ground, the thrust stroke hydraulic cylinder 3 forces the structural main frame 1 to move relative to the combined slider 6 by extending and retracting its output end and cooperating with the static friction between the combined slider 6 and the ground.

[0046] In this embodiment, there are four slide rails 4, and there are also four propulsion stroke hydraulic cylinders 3. The four propulsion stroke hydraulic cylinders 3 are located between the four slide rails 4 and correspond to the four slide rails 4 one by one. The four slide rails 4 are grouped in pairs, and the two groups of slide rails 4 are respectively arranged on the front and rear sides of the travel direction of the main structure frame 1, and the two slide rails 4 in each group are symmetrically distributed about the midline of the length direction of the main structure frame 1.

[0047] The self-moving working principle of the self-moving train of the slide rail type equipment in this embodiment is specifically as follows: when the bottom of the combined sliding block 6 touches the ground, the two combined sliding blocks 6 located on the front side of the main structure frame 1 in the direction of travel are respectively subjected to the contraction pulling force from the output end of the corresponding propulsion stroke hydraulic cylinder 3, so that the corresponding slide rail 4 moves along the direction of travel of the main structure frame 1. The two combined sliding blocks 6 located on the rear side of the main structure frame 1 in the direction of travel are respectively subjected to the extension thrust from the output end of the corresponding propulsion stroke hydraulic cylinder 3, so that the corresponding slide rail 4 moves along the direction of travel of the main structure frame 1, thereby driving the main structure frame 1 to move forward along its direction of travel through the four slide rails 4, wherein each driving stroke is ≥800mm. It takes ≤10s to complete each travel cycle. The maximum vehicle weight is ≥60T. The working pressure is 20MPa.

[0048] The lifting mechanism includes a first connecting plate 7, a second connecting plate 8 and a lifting hydraulic cylinder 5. The first connecting plate 7 is fixed to the side wall of the frame of the main structural frame 1. The first connecting plate 7 is an isosceles trapezoidal structure as a whole. The bottom edge of the isosceles trapezoidal structure is fixed to the side wall of the main structural frame 1, and the top edge is used to connect the second connecting plate 8.

[0049] The second connecting plate 8 can be inserted and fixed on the first connecting plate 7, and the lifting hydraulic cylinder 5 is inserted on the second connecting plate 8. The output end of the lifting hydraulic cylinder 5 is located below the second connecting plate 8 and perpendicular to the ground in the direction of the main structural frame 1, so that it is convenient to extend its output end to the ground to reversely lift itself and the second connecting plate 8 and the first connecting plate 7, thereby raising the distance between the main structural frame 1 and the ground, and finally realizing the suspension of the combined slider 6 relative to the ground.

[0050] Slots 9 are provided at the top and bottom of the first connecting plate 7 facing the second connecting plate 8, and two plug-in plates 81 are provided on the second connecting plate 8 facing the first connecting plate 7 to match the two slots 9. The second connecting plate 8 can be preliminarily installed and fixed on the first connecting plate 7 through the slots 9 and the plug-in plates 81.

[0051] Both sides of the first connecting plate 7 are inclined outward and contracted to form a slope (not marked), and first ear seats 12 are vertically arranged on the two slopes. The first ear seat 12 is provided with a first rod body 13 that can rotate relative to it. The first rod body 13 can rotate relatively around the first ear seat 12 on the horizontal plane of the main structural frame 1. A first rotating shaft 14 is rotatably inserted on the first ear seat 12, and the end of the first rod body 13 is sleeved and fixed on the outside of the first rotating shaft 14 to rotate synchronously with the first rotating shaft 14.

[0052] The first rod body 13 is rotatably connected with a second ear seat 16 , and the second rotating shaft 17 is rotatably inserted into the second ear seat 16 . The outer wall of the first rod body 13 is sleeved and fixed on the outer side of the second rotating shaft 17 to drive the second rotating shaft 17 to move.

[0053] A slide groove 15 is provided at one end of the second ear seat 16, and a limit block 19 is slidably connected in the slide groove 15. In this embodiment, when the first connecting plate 7 and the second connecting plate 8 are connected, the first rod body 13 and the slide groove 15 are parallel to the corresponding slope of the first connecting plate 7. When the first connecting plate 7 and the second connecting plate 8 are in a separated state, the first rod body 13 is perpendicular to the corresponding slope of the first connecting plate 7, and the slide groove 15 is inclined to the corresponding slope of the first connecting plate 7.

[0054] A second rod 18 is slidably inserted into one end of the slide 15 away from the second ear seat 16, one end of the second rod 18 is fixed to one side of the stop block 19, and a first spring 21 is sleeved on the outer side of the second rod 18, and the two ends of the first spring 21 are respectively fixed to one side of the stop block 19 and the corresponding inner wall of the slide 15. A pull ring 20 is fixed to the other end of the second rod 18, and hooks 11 parallel to the first ear seat 12 are arranged on both sides of the second connecting plate 8.

[0055] In this embodiment, when the first connecting plate 7 is connected to the second connecting plate 8, the pull ring 20 is put on the hook 11, and the first rod 13 is rotated in a direction away from the second connecting plate 8 to drive the slide groove 15 to move, forcing the second rod 18 to tighten and fix the hook 11 through the pull ring 20.

[0056] When the first connecting plate 7 and the second connecting plate 8 are in a separated state, the first spring 21 is in a non-deformed state. When the first connecting plate 7 and the second connecting plate 8 are connected, the limit block 19 will move in the slide groove 15 toward the second connecting plate 8 and compress the first spring 21. At this time, the compression deformation of the first spring 21 can help the pull ring 20 to completely tighten and fix the hook 11, so that the second connecting plate 8 continuously provides a constant pressure to the first connecting plate 7, thereby making the connection between the first connecting plate 7 and the second connecting plate 8 more stable and reliable.

[0057] A clamping groove 24 for inserting the lifting hydraulic cylinder 5 is provided on the plate surface of the second connecting plate 8 at one end away from the main structural frame 1, and two clamping plates 25 are arranged opposite to each other in the clamping groove 24, and a clamping space for clamping and fixing the lifting hydraulic cylinder 5 is formed between the two clamping plates 25, so as to facilitate clamping and fixing the lifting hydraulic cylinder 5 on the second connecting plate 8. In this embodiment, the outer shell of the lifting hydraulic cylinder 5 is provided with a docking groove (not shown) adapted to the clamping plate 25, so that the clamping plate 25 is stuck in the docking groove, so that the clamping of the lifting hydraulic cylinder 5 is more stable.

[0058] Two plug grooves 22 are oppositely opened in the second connecting plate 8, one end of the two plug grooves 22 is respectively connected to the two sides of the clamping groove 24, and the notches at the other ends of the two plug grooves 22 are respectively arranged on the side of the second connecting plate 8 facing the first connecting plate 7. The first connecting plate 7 is provided with two top blocks 27 which can be respectively inserted into the notches of the two corresponding plug grooves 22 on the second connecting plate 8.

[0059] A first piston 23 that contacts and squeezes with a top block 27 is provided at one end of each plug groove 22, and a second piston 26 is provided at the other end. A third rod (not marked) is fixed between the second piston 26 and the corresponding clamping plate 25, and hydraulic oil (not marked) is contained in the plug groove 22 between the first piston 23 and the second piston 26.

[0060] In this embodiment, when the first connecting plate 7 is connected to the second connecting plate 8, the top block 27 will be inserted into the corresponding notch of the plug groove 22 and squeeze the first piston 23. The first piston 23 is transmitted to the second piston 26, the third rod body and the clamping plate 25 through the hydraulic oil, so that the two clamping plates 25 are close to each other and respectively inserted into the corresponding docking grooves on the lifting hydraulic cylinder 5, so that the lifting hydraulic cylinder 5 is clamped and fixed between the clamping plates 25, which is convenient and quick.

[0061] Example 2

[0062] Please combine Fig.11 and Fig.12This embodiment is an improved solution of embodiment 1. A second spring (not shown) is provided between the second piston 26 and the inner wall of the adjacent plug slot 22. The second spring is sleeved on the outside of the third connecting rod. When the clamping plate 25 is in a non-clamping state, the second spring is in an uncompressed state. When the second piston 26 is driven by hydraulic oil, the second spring is compressed. The compressed second spring can help the clamping plate 25 return to the initial state when the lifting hydraulic cylinder 5 is not needed to be clamped, and the distance between the two clamping plates 25 is increased in time, so as to facilitate the lifting hydraulic cylinder 5 to pull out the clamping groove 24.
