Description

Technical Field

[0001] The invention relates to the technical field of mine construction, in particular to a filling and reinforcement method for treating a goaf area in an underground mine. Background Art

[0002] In the mining process, with the continuous exploitation of ore resources, underground spaces gradually form cavities, which are called goafs. The formation of goafs will exert pressure on the surrounding rock mass, causing the rock mass to become unstable, and then causing geological disasters such as ground collapse and cracks, which seriously threaten the life safety of miners and the surrounding ecological environment. Therefore, the management of goafs has become an important task for mine safety production and environmental protection. The existence of goafs increases the risk of casualties among miners. The management of goafs is a necessary measure to ensure the life safety of miners. Goafs may cause geological disasters and damage the surrounding ecological environment. The management of goafs is also an important means to protect the ecological environment. Through filling and reinforcement, the support points of the rock mass can be increased, its stability can be improved, and the possibility of geological disasters can be reduced. Filling and reinforcement technology is a method of filling goafs with solid waste, cementing materials or other filling materials to reduce the volume of cavities and improve the stress state of the rock mass. Commonly used filling materials include waste rock, tailings, coal gangue, concrete, etc. These materials can be selected according to the actual situation. Appropriate proportions and transportation methods.

[0003] After searching, the patent document (authorization announcement number is CN201510585644.6) includes the following steps: determine the filling borehole according to the occurrence morphology of the underground goaf; insert a feeding pipe with a tray in the borehole, insert a grouting pipe every one or several feeding pipes, inject cement mortar, and feed loose sand and gravel into the goaf through the feeding pipe to the top plate position of the goaf, and inject cement mortar through the grouting pipe to form a concrete sandwich wall in the loose sand and gravel; finally complete the filling and reinforcement construction of the entire goaf. Its advantages are: the strength of its filling body is greatly enhanced compared with the dry filling using loose sand and gravel, which can effectively limit the deformation and movement of the surrounding rock of the goaf, and obtain a satisfactory filling and reinforcement effect. Compared with the grouting and bonding filling method, it can avoid the disadvantage of a long construction period of layered grouting, which can not only save a lot of cost, but also greatly improve the construction efficiency.

[0004] However, the above device still has shortcomings:

[0005] During the filling operation, the pipe needs to be moved to the appropriate position and the track needs to slide repeatedly. If the track cannot be lubricated in time, the service life of the device will be greatly reduced. Summary of the invention

[0011] Step 4: Finish the job: After filling is complete, put away the device.

[0012] Preferably, the driving slide rod is arranged in the track slide groove and has small blocks fixedly connected at both ends. The track slide groove is provided with a plurality of component housings. The component housings are respectively provided with driving components for providing a driving source and lubrication components for auxiliary lubrication.

[0013] Preferably, the driving component includes a main driving rack, which is fixedly connected to a small block, and a partition and a recovery block are fixedly connected to a side of the small block close to the main driving rack, and a spacer is fixedly connected to the top of the partition, and a first round rod is fixedly connected to the inside of the component shell, and a driven gear is rotatably connected to the outer side of the first round rod, and the driven gear and the main driving rack are meshed and connected, and a trapezoidal block is slidably connected to the outer side of the first round rod, and the trapezoidal block is arranged on a side of the driven gear close to the partition.

[0017] Preferably, a plurality of barrier blocks are fixedly connected to the inner wall of the lubricating liquid storage bin, and the barrier blocks are evenly distributed on both sides of the pressure plate.

[0018] Preferably, a nozzle is fixedly connected to the outer side of the lubricating liquid storage bin, and a pressure-triggered pump body is fixedly connected to the inner side of the nozzle.

[0019] Preferably, a groove is formed on one side of the component housing close to the driving slide rod, and the small block is slidably connected in the groove.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] During work, when the driving slide rod moves downward, it meshes with the driven gear, thereby driving the driven sprocket to rotate, and the driven sprocket drives the driven gear plate downward.

The motor can drive the driving slide rod 104 to slide in the track slot 103, so that the injection pipe 106 can be extended to the place where filling is required when working, and can be retracted when not working;

[0038] Step 3: Work starts: the filler is filled into the designated position through the device;

[0039] Step 4: Finish the job: After filling is complete, put away the device.

[0040] The driving slide rod 104 is arranged in the track slide groove 103, and both ends are fixedly connected with small blocks 1041. The track slide groove 103 is provided with a plurality of component housings 2. The component housing 2 has a groove 21 on one side close to the driving slide rod 104. The small block 1041 is slidably connected in the groove 21. The component housing 2 is provided with a driving component 3 for providing a driving source and a lubrication component 4 for auxiliary lubrication.

[0041] The driving component 3 includes a main driving rack 31, which is fixedly connected to the small block 1041. A partition 32 and a recovery block 33 are fixedly connected to the side of the small block 1041 close to the main driving rack 31. A partition block 321 is fixedly connected to the top of the partition 32. A first round rod 34 is fixedly connected to the inside of the component housing 2.

Through the arrangement of the partition 32, the driven gear 35, the partition block 321 and the recovery block 33, when the driving slide bar 104 moves, it can only drive the driven gear 35 to rotate when it moves downward, and it cannot be driven when it moves upward, thereby effectively avoiding the driven gear 35 from rotating too frequently, thereby causing waste of resources.

[0042] The outer side of the first round rod 34 is fixedly connected with an assisting circular plate 37, the outer side of the first round rod 34 is provided with an opening and closing groove 61, the inner side of the first round rod 34 is fixedly connected with an inner rod 6, the assisting circular plate 37 is arranged on the side of the driven gear 35 away from the partition 32, the outer side of the first round rod 34 is sleeved with a first spring 38, the two ends of the first spring 38 are respectively fixedly connected to the component housing 2 and the assisting circular plate 37, the inner wall of the assisting circular plate 37 is fixedly connected with a short tooth 371, and the end of the short tooth 371 is slidably connected with a fixed The slider 372 and the inner wall of the short tooth 371 are provided with a push spring 373, and the two ends of the push spring 373 are respectively fixedly connected to the fixed slider 372 and the short tooth 371, and the short tooth 371 is slidably connected in the opening and closing groove 61. The side wall of the inner rod 6 is provided with a fixed groove 62, and the fixed slider 372 is clamped in the fixed groove 62 to achieve the overall fixing effect of the driven gear 35, so as to prevent the driven gear 35 from sliding on the first round rod 34, resulting in the rotation of the driven gear 35 when moving upward.

[0043] The lubrication assembly 4 includes a second round rod 41, which is rotatably connected to the inner wall of the assembly housing 2. A driving turntable 42 is fixedly connected to the outer side of the second round rod 41. A small toothed disc 43 is fixedly connected to the second round rod 41. A limiting circular plate 431 is fixedly connected to the outer side of the small toothed disc 43. The small toothed disc 43 and the driven gear 35 are meshed with each other. The driven gear 35 can be driven without the need for an additional power source, which can greatly reduce the use of the engine and avoid excessive heat generated by the engine, which causes the overall temperature of the device to rise.

[0044] The component housing 2 is fixedly connected to a lubricating liquid storage bin 5, and the lubricating component 4 includes a second round rod 41, and a transmission belt 44 is sleeved on the outer side of the second round rod 41. The bottom of the transmission belt 44 extends into the lubricating liquid storage bin 5, and the lubricating liquid storage bin 5 is rotatably connected to a driven gear disc 45. One end of the transmission belt 44 extending into the lubricating liquid storage bin 5 is sleeved on the outer side of the driven gear disc 45. The lubricating liquid storage bin 5 is slidably connected to a pressure plate 47, and a driven gear plate 46 is arranged above the pressure plate 47. The driven gear plate 46 is slidably connected to the inner wall of the lubricating liquid storage bin 5, and the driven gear plate 46 and the driven gear disc 45 are meshed with each other. The bottom of the driven gear plate 46 is slidably connected to a connecting small plate 461, and a reset spring is arranged inside the driven gear plate 46. Spring 462, both ends of the return spring 462 are fixedly connected to the connecting plate 461 and the driven gear plate 46, and the bottom of the connecting plate 461 is fixedly connected to the pressure plate 47. When the driving slide rod 104 moves downward, it engages with the driven gear 35, thereby driving the driven gear plate 45 to rotate, and the driven gear plate 45 drives the driven gear plate 46 to move downward. Due to the presence of the return spring 462 and the blocking block 48, the return spring 462 can accumulate elastic potential energy until it reaches the critical point. The pressure plate 47 moves downward rapidly and squeezes the lubricating liquid through the nozzle 51 to achieve a quantitative spraying effect, which can greatly reduce the waste of resources. The outer side of the lubricating liquid storage bin 5 is fixedly connected with the nozzle 51, and the inside of the nozzle 51 is fixedly connected with a pressure-triggered pump body 511.

[0045] A plurality of barrier blocks 48 are fixedly connected to the inner side wall of the lubricating liquid storage bin 5 , and the barrier blocks 48 are evenly distributed on both sides of the pressure plate 47 .

[0046] Working principle: The motor drives the driving slide bar 104 to move up and down, so that the injection pipe 106 can extend into the filling area, thereby achieving the filling effect. When the driving slide bar 104 slides downward in the track slide groove 103, the partition plate 32 contacts the trapezoidal block 36, and the extrusion effect of the partition plate 32 pushes the driven gear 35 to move in the direction close to the first spring 38. At this time, the driven gear 35 and the main driving rack 31 are meshed, and the main driving rack 31 drives the driven gear 35 to rotate. Through the transmission of the driven gear 35, the driving turntable 42 drives the driven gear plate 45 to rotate through the transmission belt 44, so that the driven gear plate 46 can push the plate pressure plate 47 to move, so that the lubricating liquid is sprayed out through the nozzle 51;

[0047] When the driven tooth plate 46 moves downward, the pressure plate 47 will not move immediately. Due to the existence of the blocking block 48, it will block the blocking block 48 from moving forward. However, as the driven tooth plate 46 moves downward multiple times, the elastic potential energy accumulated by the return spring 462 becomes more and more, and finally the pressure plate 47 will break away from the obstruction of the blocking block 48 and be blocked by the next group of blocking blocks 48. The lubricating fluid pressurized by the movement of the pressure plate 47 will be sprayed out through the nozzle 51 to achieve the lubrication effect on the track slide 103.

[0048] As the driving slide bar 104 moves downward, the spacer block 321 will eventually contact the trapezoidal block 36, and the spacer block 321 will push the trapezoidal block 36 to move closer to the first spring 38 again, so that it is out of engagement with the main driving rack 31. At this time, the fixed slider 372 will also be engaged in the fixed groove 62, achieving the effect of fixing the driven gear 35.

[0049] When the driving slide bar 104 moves upward, the driven gear 35 disengages from the main driving rack 31 due to the influence of the spacer block 321. However, as the driving slide bar 104 continues to move upward, the restoration block 33 contacts the driven gear 35, and the restoration block 33 pushes the driven gear 35 back to its original position, preparing for the next engagement with the spacer block 321.

[0050] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
