Description

Technical Field

[0001] This invention relates to the field of fully mechanized mining face technology, and in particular to a self-moving platform train for fully mechanized longwall mining faces. Background Technology

[0002] A fully mechanized longwall face refers to the process in which coal mining machines, conveyors, and supports work together on the working face to complete coal mining and transportation. The work process of a fully mechanized longwall face includes: preparation, coal mining operations, support operations, transportation operations, and safety inspections.

[0003] Currently, most transport roadways in fully mechanized mining faces in China utilize long-distance power and fluid supply. However, some equipment still needs to be moved along with the working face. This includes multi-combination switches for the working face, centralized control equipment for the working face, power cables laid in the roadway as the working face advances, and commonly used accessories and tools for fully mechanized mining faces. All of these devices need to be fixed on flatbed carts, with each flatbed cart connected end-to-end. A winch is installed at the entrance of the roadway, and tracks are laid on one side of the conveyor belt in the roadway. The winch drives the flatbed carts forward along the working face. This pulling method is prone to accidents such as slippage in undulating roadways, posing a significant safety hazard. At the same time, the need to lay tracks on one side of the conveyor belt to form a transport system results in narrow roadway space and makes it extremely difficult to construct continuous auxiliary transport. Summary of the Invention

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] Please refer to the following: Figures 1 to 9The present invention will now describe a specific embodiment of a self-moving platform train for a fully mechanized mining face. This type of self-propelled platform train for fully mechanized mining faces includes an equipment platform car 1, a cable platform car 2, a central control platform car 3, limiting posts 4, and braking components 8. Multiple equipment platform cars 1 are mounted on rails 5 and are connected to adjacent equipment platform cars 1 via a first connecting member 6, used to house multiple combination switches. Cable platform cars 2 are mounted on rails 5 and connected to equipment platform cars 1 at one end, used for cable retrieval. Central control platform cars 3 are mounted on rails 5 and connected to equipment platform cars 1 at the other end, used to house the fully mechanized mining face central control equipment, toolboxes, and spare parts boxes. Limiting posts 4 are connected to cable platform cars 2 and / or central control platform cars 3, used to limit the displacement of cable platform cars 2 and / or central control platform cars 3. Multiple braking components 8 are provided and connected to adjacent equipment platform cars 1 and cable platform cars 2 respectively. The multiple braking components 8 work together to limit the movement of equipment platform cars 1 and cable platform cars 2.

[0055] For ease of explanation, please refer to the following: Figure 4 and Figure 5 A rectangular coordinate system is established with any point in space as the origin, the setting direction of the first guardrail 12 in the equipment platform vehicle 1 relative to the equipment vehicle body 11 as the Z-axis, the movement direction of the equipment platform vehicle 1 as the X-axis, and the straight line direction that is perpendicular to both the X-axis and the Z-axis as the Y-axis. In this system, the XY plane is a horizontal plane, the direction indicated on the horizontal plane is the horizontal direction, the direction indicated by the Z-axis is the vertical direction, i.e., the up and down direction, the X-axis indicates the front and back direction, and the Y-axis indicates the left and right direction.

[0056] In this embodiment, the limiting strut 4 can be a hydraulic strut. The hydraulic struts can be arranged simultaneously at the front and rear depending on the conditions of the roadway. If the roadway has a uniform slope without any ups and downs, two sets of limiting struts 4 can be arranged only in the downhill direction of the roadway. Several cable platform vehicles 2 are provided, and adjacent cable platform vehicles 2 are connected by a second connector 7. The equipment platform vehicle 1 and the central control platform vehicle 3 are connected by a third connector. For example, if there are two equipment platform vehicles 1 and two cable platform vehicles 2, then from front to back, they are: limiting strut 4, central control platform vehicle 3 for placing the central control equipment, toolbox, and spare parts box of the fully mechanized mining face, two equipment platform vehicles 1 for placing multiple combination switches, two cable platform vehicles 2 for cable recovery, and limiting strut 4.

[0057] In this embodiment, the third connecting member, the first connecting member 6, and the second connecting member 7 can all be metal connecting rods or connecting plates. The connecting rods are hinged to the structures located on the front and rear sides. The connecting rods are welded from thick steel plates and profiles, and each end of the connecting rod has a Φ52mm hinge hole with a hole spacing of 500mm. The connecting rods and the car body are hinged by a pin, and an anti-pin slippage structure is added to increase the strength of the connection. There are two tracks 5, which are respectively set on both sides of the conveyor belt 10. The tracks 5 are arranged on sleepers made of channel steel, and pressure plates are arranged at both ends of the channel steel to fix the tracks 5 and the sleepers. The equipment platform car 1, the cable platform car 2, and the centralized control platform car 3 are all installed on the tracks 5 and span across the conveyor belt 10.

[0058] In this embodiment, the device uses the emulsion pump station at the fully mechanized mining face as the power source, eliminating the need for a separate power source. It employs hydraulic movement and does not require a winch. The braking device adopts a fail-safe structure and is existing technology, so it will not be described in detail here. When a hydraulic pipeline malfunctions, the braking device automatically locks the track 5 to prevent the equipment from slipping, demonstrating high reliability. It can completely prevent runaway accidents caused by hydraulic cylinder leakage or hydraulic lock failure. Furthermore, anti-runaway structures such as limit posts 4 are installed on both sides of the vehicle body to effectively ensure driving safety during movement.

[0059] Compared with existing technologies, this type of self-moving platform train for fully mechanized mining faces effectively prevents problems such as insecure fixing, easy slippage, cumbersome locking and unlocking steps, and inconvenient operation when the device is not moving, thanks to the setting of the limiting column 4. The limiting column 4 automatically locks and unlocks through hydraulic control, effectively improving work efficiency. The braking component 8 can limit movement during the process, preventing slippage when traveling in undulating roadways, thus improving safety performance during use.

[0060] As another embodiment of the present invention, the structure of the self-moving platform train for the fully mechanized mining face is basically the same as that in the above embodiment. The difference is that the limiting strut 4 includes a strut 41, a first driver 42, a telescopic support 43, and a second driver 44. One end of the strut 41 is rotatably connected to the cable platform vehicle 2 or the centralized control platform vehicle 3, and the other end is used to abut against the ground. One end of the first driver 42 is rotatably connected to the strut 41, and the other end is rotatably connected to the cable platform vehicle 2 or the centralized control platform vehicle 3, and is used to drive the strut 41 to rotate. One end of the telescopic support 43 is rotatably connected to the strut 41, and the other end is used to abut against the top plate. The second driver 44 is rotatably connected to both the strut 41 and the telescopic support 43, and is used to control the movement of the telescopic support 43.

[0061] In this embodiment, the telescopic support 43 includes a first column and a second column. The first column is rotatably connected to the strut 41; the second column is slidably connected to the first column and rotatably connected to the second actuator 44. The end of the second column away from the first column abuts against the roof plate. The second actuator 44 is used to control the rotation of the telescopic support 43 so that the telescopic support 43 is always perpendicular to the ground. The first column and the second column are hydraulically controlled to control their relative position, that is, to control the second column to slide along the first column until it abuts against or separates from the roof plate. The roof plate can be the top of the tunnel. Any structure that can achieve the function of the telescopic support 43 is within the scope of protection of this application. The end of the strut 41 near the ground is provided with a groove adapted to the track 5. The strut 41 can cross the track 5 and be inserted into the bottom plate, which is the bottom of the tunnel.

[0062] In this embodiment, the telescopic support 43 is a hydraulic support. The end of the telescopic support 43 furthest from the strut 41 is provided with several ratchet teeth. These ratchet teeth increase the friction between the telescopic support 43 and the top plate, thereby ensuring the stability of the telescopic support 43 during support. Both the first actuator 42 and the second actuator 44 can be hydraulic cylinders. Two sets of limiting struts 4 are arranged at both ends of the device to prevent the device from sliding along with the track 5. When the device does not need to move, the first actuator 42 extends, lowering the strut 41; the second actuator 44 adjusts the angle between the telescopic support 43 and the ground until the telescopic support 43 is perpendicular to the top plate. The telescopic support 43 extends under hydraulic drive, pressing against the top plate and simultaneously compacting the strut 41, thus achieving the limiting and fixing of structures such as the equipment platform vehicle 1. When the device needs to move, the telescopic support 43 retracts, retracting the second actuator 44, and finally retracting the first actuator 42, causing the limiting struts 4 to disengage from the top and bottom plates.

[0063] As another embodiment of the present invention, the structure of this self-moving platform train for the fully mechanized mining face is basically the same as that in the above embodiments, except that the equipment platform vehicle 1 includes an equipment body 11, a first guardrail 12, and a mounting frame 13. The equipment body 11 is connected to the track 5 and moves along the track 5; the first guardrail 12 is connected to the equipment body 11 and is located on the side of the equipment body 11 away from the track 5; the mounting frame 13 is connected to the equipment body 11 and is located on one side of the first guardrail 12, used to fix multiple combination switches, and the mounting frame 13 and the first guardrail 12 are spaced apart. The first guardrail 12 is used for protection to prevent workers or equipment from falling, and the gap between the mounting frame 13 and the first guardrail 12 is used for workers to move, facilitating workers to load, unload, and maintain the equipment. The mounting frame 13 can be a frame structure welded from multiple angle steels.

[0064] As another embodiment of the present invention, the structure of this self-propelled platform train for the fully mechanized cable laying face is basically the same as that in the above embodiments. The difference is that the cable platform vehicle 2 includes a cable vehicle body 21 and columns 22. The cable vehicle body 21 is connected to the track 5 and moves along the track 5. The columns 22 are connected to the cable vehicle body 21 and are located on the side of the cable vehicle body 21 away from the track 5. Several columns 22 are provided for winding and fixing cables. Several columns 22 are symmetrically arranged on the left and right sides of the cable vehicle body 21, with a gap between adjacent columns 22. The spaced columns 22 facilitate winding and fixing more cables and also facilitate the movement of workers between the columns 22, thereby ensuring the efficiency of cable installation and removal. The columns 22 and the track 5 are respectively located on the upper and lower sides of the cable vehicle body 21.

[0065] As another embodiment of the present invention, the structure of this self-moving platform train for the fully mechanized mining face is basically the same as that in the above embodiments. The difference is that the centralized control platform vehicle 3 includes a centralized control vehicle body 31, a second guardrail 32, and a control cabinet 33. The centralized control vehicle body 31 is connected to the track 5 and moves along the track 5; the second guardrail 32 is connected to the centralized control vehicle body 31 and is located on the side of the centralized control vehicle body 31 away from the track 5; the control cabinet 33 is connected to the centralized control vehicle body 31 and is located on one side of the second guardrail 32. The control cabinet 33 is spaced apart from the second guardrail 32 and is electrically connected to the centralized control vehicle body 31, the equipment platform vehicle 1, the cable platform vehicle 2, and the limiting column 4, for controlling the opening and closing of the centralized control vehicle body 31, the equipment platform vehicle 1, the cable platform vehicle 2, and the limiting column 4. Both the first guardrail 12 and the second guardrail 32 can be sliding doors composed of mesh panels.

[0066] As another embodiment of the present invention, the structure of the self-moving platform train for the fully mechanized mining face is basically the same as that in the above embodiment. The difference is that the equipment body 11 includes a support platform 111, a frame 112, wheels 113, and a ladder 114. The support platform 111 is connected to the first guardrail 12 and the mounting frame 13. The frame 112 is connected to the support platform 111 and is located on the side of the support platform 111 away from the first guardrail 12 and the mounting frame 13. The wheels 113 are connected to the track 5 and are rotatably connected to the frame 112 through axle brackets 115. The wheels 113 and axle brackets 115 correspond one-to-one. The ladder 114 is connected to the frame 112. The ladder 114 is made of metal. For example, the ladder 114 can be a steel ladder.

[0067] In this embodiment, the equipment vehicle body 11, cable vehicle body 21, and central control vehicle body 31 have basically the same structure; the equipment platform vehicle 1 and the cable platform vehicle 2 are connected by a fourth drive 9. Two fourth drive 9s are arranged side-by-side, serving as push jacks. This device is hydraulically controlled, with hydraulic hoses laid under the support platform 111 and neatly fixed to the frame 112, ensuring sufficient operating space for maintenance personnel. The cables and hydraulic hoses of this device are fixed to the cable platform vehicle 2 via cable brackets. The cables and hydraulic hoses between the two fourth drive 9s are suspended by cable brackets fixed to the cable platform vehicle 2. The height of the cable brackets is 1-1.5 meters, ensuring a cable slack of 2-2.5 meters, and the height is adjustable. The power for the movement of this device is provided by the two fourth drive 9s, which are connected in series and ensure synchronous operation.

[0068] As another embodiment of the present invention, the structure of this self-propelled platform train for the fully mechanized mining face is basically the same as that in the above embodiment, except that there are two braking components 8, which are respectively connected to the adjacent equipment platform car 1 and cable platform car 2. When the device moves, the two braking components 8 located on the equipment platform car 1 and cable platform car 2 work separately. Specifically, when moving, the two braking components 8 work alternately, that is, one set is open and separated from the track 5, and the other set must be braked, so as to prevent the car from slipping while moving. That is, when the cable platform car 2 is braked, the push jack pushes the equipment platform car 1 to move. When the equipment platform car 1 is braked, the cable platform car 2 moves forward under the action of the push jack. This reciprocating motion realizes the movement of the entire structure. When not moving, both braking components 8 are braked.

[0069] In this embodiment, the braking assembly 8 includes an anti-slip assembly 81 and a rail clamp 82. The anti-slip assembly 81 is rotatably connected to the equipment platform vehicle 1 or the cable platform vehicle 2, and multiple anti-slip assemblies are provided for ground contact and limiting. The rail clamp 82 is connected to the equipment platform vehicle 1 or the cable platform vehicle 2, and multiple rail clamps are provided for contact and fixation with the rail 5. Several anti-slip assemblies 81 are symmetrically arranged on the front and rear sides of the rail clamp 82. The rail clamp 82 is prior art; therefore, any device capable of achieving the aforementioned performance functions of the rail clamp 82 is within the scope of protection of this application.

[0070] As another embodiment of the present invention, the structure of the self-moving platform train for the fully mechanized mining face is basically the same as that in the above embodiments. The difference is that the anti-slippage component 81 includes a limiting post 811 and a third drive 812. One end of the limiting post 811 is rotatably connected to the equipment platform vehicle 1 or the cable platform vehicle 2, and the other end is used to abut against the ground. One end of the third drive 812 is rotatably connected to the equipment platform vehicle 1 or the cable platform vehicle 2, and the other end is rotatably connected to the limiting post 811. The third drive 812 is electrically connected to the centralized control platform vehicle 3 and is used to drive the limiting post 811 to rotate. The third drive 812 is a hydraulic cylinder. When the device needs to remain stationary, the third drive 812 is raised, the limiting post 811 presses against the base plate, and the rail clamp 82 clamps the rail 5. When the device needs to move, the third drive 812 is pulled up, the limiting post 811 is raised and disengaged from the base plate, and the rail clamp 82 opens and disengages from the rail 5.

[0071] Compared with existing technologies, this self-propelled platform train for fully mechanized longwall mining faces adopts a method of crossing the roadway belt conveyor 10, uses the emulsion fluid of the longwall mining face as power, and employs hydraulic cylinder connections, hydraulic rail clamps 82, and hydraulic struts to achieve hydraulic braking and hydraulic propulsion. This completely changes the traditional pulling method, eliminating its drawbacks and safety hazards. The hydraulic transmission used in this device has advantages such as smooth low-speed transmission, high load-bearing capacity, easy overload protection, low maintenance costs, and simple mechanism for easy operation. This device is mainly suitable for transport roadways in fully mechanized mining faces, used to install combination switches, centralized control equipment, toolboxes, spare parts boxes, and store cable hoses, and can be dragged along as the working face moves.
