Description

An advanced support system and support method for anchor net support

technical field

The invention relates to the field of advance support for coal mine roadways, in particular to an advance support system and a support method for anchor net support.

Background technique

With the continuous improvement of the degree of mechanization of fully mechanized mining faces, under suitable geological conditions, major coal mines in my country have gradually used advanced support hydraulic supports. According to structural characteristics, advanced supports can be divided into: large mining height four-link advanced support hydraulic pressure Supports, self-moving hydraulic supports for advanced support, hydraulic supports for straddle-type advanced supports, and crawler-type advanced support hydraulic supports. The first three kinds of advance support hydraulic supports all need to take actions such as lowering, pulling (or pushing), lifting, adjusting, and then lowering and lifting when moving the frame. That is to say, there are technical defects in repeatedly supporting the roof, which is very destructive to the stability and integrity of the roof, and will bring great hidden dangers to subsequent frame removal, support and safe mining. For the crawler type advance support hydraulic support, this will successfully avoid the repeated support of the roof from breaking. However, the sliding friction produced by such a frame moving method will seriously affect the service life of the support, and will bring defects such as large forward resistance and extremely unstable walking, which will easily cause harm to the safety of roadway personnel.

At the same time, for all the current traditional advanced supports, the structure of pushing and moving the frame is mostly adopted, and the pushing and moving of the frame may cause problems such as the deflection of the support, the rollover of the support, and the difficulty of moving the frame.

These difficult problems are relatively related. If one problem is not solved well, other problems will gradually emerge, which will cause great hidden dangers to coal mining safety.

The method for supporting by the advanced support system for anchor net support according to the present invention comprises the following steps:

(A) transport the cylindrical roller, fixed nut, first connector, second connector, front roof beam guard plate and rear roof beam guard plate of the cylindrical pressure bearing row to the underground advance support area;

Transport the guide plate, load-bearing block and anti-drilling baffle to the side of the advanced hydraulic support, dig a small trench with a depth of 20mm at the front end of the advanced hydraulic support base, and gradually install the lower fixing plate of the load-bearing block along the base of the advanced hydraulic support. Insert, insert at least 500mm, when the resistance is too great to push in, stop the manual work, keep the personnel away from the support, move the frame through the advanced hydraulic support, and gradually make the load-bearing block reach the front end of the advanced hydraulic support base; stop moving the frame, use a hammer Beat the load-bearing block front and back, make it aligned with the base, make it parallel and close to the base;

(B) The iron rods of each cylindrical roller are installed with the first connecting piece and the second connecting piece, and are connected to form a cylindrical pressure-bearing row. At the beginning, the cylindrical pressure-bearing row is installed to 4m, wherein, on both sides of the first cylindrical roller, Only one first connecting piece or second connecting piece needs to be installed on each side to connect the rear cylindrical roller. When the first cylindrical roller rolls out of the advanced hydraulic support, the fixing nut can be unscrewed and connected to the advanced hydraulic support The front is used in succession; when installing for the first time, the front column of the advanced hydraulic support releases the pressure, so that the front end of the roof beam is separated from the roof by 70-80mm, stops the pressure relief, and inserts the horizontal plate of the pressure bearing plate between the advanced hydraulic support and the roof of the roadway , plug the installed cylindrical pressure row into the gap between the top plate and the top beam;

(C) Rotate the upper fixing plate to the top of the load-bearing block, connect the upper fixing plate and the lower fixing plate through the second fixing strip and tighten and fix it; put it into the guide plate, the direction of the knife edge at the bottom of the guide plate is in front of the moving direction, Use a hammer to hit the guide plate to the corresponding position of the fixing hole, insert the pin, fix the pin, and insert a small amount of burlap or jute at the place where the back side of the fixing groove and the left and right sides are in contact with the guide plate to reduce the gap between the iron blocks. The rigid contact minimizes the guide error caused by the 2mm gap to the guide plate;

(D) Do not stand within 3m of the support to prevent the roof from leaking and hurting people when moving the frame. Check the condition in front of the advanced hydraulic support to ensure that the moving path is flat, start to push the jack, and move the frame with pressure; when the cylindrical pressure-bearing row just When rolling to the middle of the top beam of the advance support, release the pressure on the rear column of the advance hydraulic support, so that the rear end of the top beam is 70-80mm away from the roadway roof, stop the pressure relief, and insert the second fixing plate of the fixing device between the advance hydraulic support and the roadway roof In between, tie the first fixing strip to the rear end of the top beam of the support, and lock it with a fixed lock, and fix the second fixing plate and the collecting tank behind the top beam of the advanced hydraulic support;

(F) After completing the initial use, adjust the pressure values of the front and rear columns so that the pressure of the front and rear columns is equivalent to the original normal pressure value, and ensure that the top beam of the bracket is parallel to the roof of the roadway and the support is stable;

(G) Take every 2m advance of the leading hydraulic support as a cycle, and every 2m advance, remove the redundant cylindrical rollers in the horizontal bottom plate and install them on the front, so 2m is a cycle.

The difference between the advanced support system of the present invention and the prior art for anchor net support lies in:

In the traditional method, when the working face advances, the advanced hydraulic support also needs to be advanced. In the process of advancing, the pressure is released first, and when the top beam of the support is separated from the roof of the roadway by a certain distance, it is advanced. After the distance, jack up the bracket again, because the route of the bracket will not follow a straight line during the process of moving, so it needs to be adjusted, and the pressure is released again to ensure that it will not press the support anchor rod and anchor cable of the roof. Therefore, the roof is severely broken during this process, which will leave a great hidden danger to the later coal mining. The broken roof will cause leakage of gas, water, gas, etc., especially when the rear support moves, a large number of roof gravels will collapse. , causing a large number of unnecessary impacts on safe production and certain potential safety hazards.

The improved roof support body of the present invention lays a cylindrical pressure-bearing row between the roof and the top beam of the support, so that the pressure can be directly carried in the form of rolling friction, and the support can be pushed from the back through the jack, so that the support does not need to be decompressed and reinstalled. Push it forward like this, and it will hardly cause any damage to the top plate. The device of the invention has the advantages of simple structure, low cost, convenient operation, reliability and practicality.

Many traditional advanced support supports need to set anchorage points, but the process of setting anchor points is cumbersome and inefficient, and it is impossible to realize fast and safe advance hydraulic support support; It causes movement deflection and difficulty in moving the frame, which greatly affects coal mining efficiency and coal mine safety production work.

The guide device of the floor supporting body of the present invention is safe, practical, simple and reliable, and improves the coal mining efficiency and the safe production work of the coal mine.

On-site experience shows that most of the side slipping and falling of the bracket base occur during the moving process, so it is necessary to go undercover before moving the bracket, set anchor points, and pull it forward bit by bit. After the bracket shifts, it needs to be reinstalled. Use a jack to push back the base point of the layout, so that it is difficult for the bracket to return to its original position in one step. At the same time, it is extremely dangerous near the end when the bracket is toppled. The route moves, the guide plate and the load-bearing block have the function of preventing the base from slipping, the base is stable, and the safety of the frame is greatly improved. At the same time, the structure of the present invention is simple, reliable and practical. This simple structure is highly reliable for complex geological environments underground. The utility model has strong practicability, and greatly improves the coal mining efficiency and the safety production work of the coal mine.

The present invention is designed for the condition that the roof of the roadway is supported by anchor nets. The distance between the top of the high-strength resin plate and the roof of the roadway is 20 mm to 40 mm to ensure that the cylindrical pressure row will not be affected by the anchor net before entering the roof and roof beam. Scratching, bumping and hooking ensure the stable operation of the whole device. At the same time, the high-strength resin material also ensures that the board itself will not suffer too much loss and will not cause hidden dangers such as sparks. The entire design is reasonable, reliable and stable.

Detailed ways

Example 1

As shown in Figures 1 to 10, an advanced support system for anchor net support includes a roof support body and a bottom plate support body. The roof support body includes an advanced hydraulic support 1 and a cylindrical pressure-bearing row 2. The pressure-bearing row 2 is composed of a plurality of cylindrical rollers 201 connected in series. The cylindrical pressure-bearing row 2 is arranged between the top beam of the leading hydraulic support 1 and the roof 3 of the roadway. When the leading hydraulic support 1 advances, the cylindrical rollers 201 Rolling; a cylindrical pressure-bearing row 2 is laid between the roadway roof 3 and the top beam of the leading hydraulic support 1, so that the pressure can be directly carried in the form of rolling friction, and the leading hydraulic support 1 is pushed from behind by a jack, so that there is no need to vent Pressurize again, directly advance like this, almost can not cause any damage to roadway roof 3. The width of the bracket is 450mm, the length of the cylindrical roller 201 is 450mm, and the diameter is 62mm. If it is too small, the top plate may be in direct contact with the top beam and cannot play the role of rolling friction. If it is too large, the gap between the pressure-bearing cylinders will also If the size is increased, the crushed rocks on the top plate will sink, which may cause the pressure-bearing cylinder to not rotate and cannot play the role of sliding friction. Therefore, this size is relatively reasonable and scientific.

The front end of the roof beam of the advanced hydraulic support 1 is provided with a front roof beam guard plate, and the rear end is provided with a rear roof beam guard plate; The rear end of the baffle plate 4 is connected to the front end of the top beam of the leading hydraulic support 1, and the front end of the plate-type pressure-bearing baffle plate 4 is connected to the rear end of the strip-type holding funnel 5;

An anchor net is laid on the roof 3 of the roadway, and an anti-seize baffle 8 is arranged on the arc-shaped connecting portion 502; Two, the bottom end of the fixed rod 801 is fixed on both sides of the arc-shaped connection part 502, the top of the fixed rod 801 is welded to the middle part of the plane clamp 802, and the plane clamp 802 clamps and fixes the high-strength resin plate 803; the high-strength resin plate 803 The distance from the top of the roadway roof 3 to the roadway roof 3 is 20mm to 40mm, the width is consistent with the width of the advanced hydraulic support 1, and the angle between the plane where the high-strength resin plate 803 is located and the plane where the roadway roof 3 is located is 15°.

When the high-strength resin plate 803 wears more than 50mm, loosen the fixing rod 801, readjust the high-strength resin plate 803 to an angle of 15° to the plane where the roadway roof 3 is located, and the distance between the top and the roadway roof 3 is between 20-40mm and fixed.

The high-strength resin plate 803 is made of high-strength resin, because the friction between iron and other materials and the anchor net or roadway roof 3 will cause hidden dangers such as high temperature, heat and sparks; It is a very targeted design, which can block sand and gravel and prevent broken metal mesh from being involved in the cylindrical pressure row 2. It should be emphasized that the two parameters of 20mm-40mm and 15° are very important, and they are unique designs for the case of laying anchor nets on the roof, and other parameters cannot be satisfied.

The floor support body includes a load-bearing block 9, an anti-drilling bottom baffle plate 10 and a guide plate 11. The load-bearing block 9 is connected to the front end of the base of the leading hydraulic support 1, and a fixed groove 12 that penetrates up and down is provided in the middle of the load-bearing block 9. Guide plate 11 is provided with in groove 12, and anti-drill bottom baffle plate 10 is arc plate, and its lower end links to each other with the front end of the bottom of bearing block 9, and the middle part of arc plate protrudes to the bottom of the advancing direction of leading hydraulic support 1.

The guide plate 11 comprises a third fixed plate 301 and a cutting portion 302 connected to the bottom of the third fixed plate 301, a fourth fixed plate 901 is respectively arranged on both sides of the longitudinal direction of the fixed groove 12, and a fourth fixed plate 901 is arranged on the fourth fixed plate 901. There is a bolt hole 902, and a fixing hole 303 is provided on the third fixing plate 301, and the fixing hole 303 and the bolt hole 902 fix the third fixing plate 301 on the fourth fixing plate 901 by a bolt; the cutting part 302 is a knife, and the knife back and The bottom of the third fixed plate 301 is connected, and the bottom of the rear end of the cutter is connected with the front end of the back of the knife to form an arc-shaped blade.

The floor of the roadway is a medium-hard floor, and the allowable uniaxial compressive strength is 22.50-42.00MPa. The distance between the fixing hole 303 and the bottom end of the cutting part 302 is H+100mm, where H is the thickness of the base of the advanced support. The unit is mm. Considering the demand relationship between the cutting resistance of the floor and the lateral pressure provided by the steering, after many experiments, when the floor type is a medium-hard floor, the size of H+130mm is the most suitable, and other sizes cannot be realized .

Above scheme just can finish object of the present invention, on this basis, proposes following preferred scheme again:

The axial direction of the cylindrical roller 201 is perpendicular to the advancing direction of the advanced hydraulic support 1; a cylindrical iron rod 202 is respectively extended outward from the center of the two ends of the cylindrical roller 201, and the direction of the iron rod 202 is parallel to the cylindrical roller 201. The outer end of 202 has a threaded structure 203 and a fixing nut 204 matched with the threaded structure 203;

The iron rods 202 of the first and last cylindrical rollers 201 are provided with a first connecting piece or a second connecting piece, and the iron rods 202 of other cylindrical rollers 201 are provided with a first connecting piece and a second connecting piece ;

The first connector includes a first connecting rod 205 and two first sleeves 206 respectively fixed at both ends of the first connecting rod 205, the first sleeve 206 is a hollow cylinder with two ends open, the first sleeve 206 The inner diameter is larger than the diameter of the iron rod 202, one of the first sleeves 206 is sleeved on the iron rod 202, and the other first sleeve 206 is sleeved on the iron rod of the previous cylindrical roller 201;

The second connector includes a second connecting rod 207 and two second sleeves 208 respectively fixed at the two ends of the second connecting rod 207, the second sleeve 208 is a hollow cylinder with two ends open, the second sleeve 208 The inner diameter is larger than the diameter of the iron rod 202, one of the second sleeves 208 is sleeved on the iron rod 202, and the other second sleeve 208 is sleeved on the iron rod 202 of the last cylindrical roller 201, and they are connected in sequence to form a cylindrical pressure bearing row. 2. Screw the fixing nut 204 on the threaded structure 203, and the entire cylindrical pressure-bearing row 2 can bend and move freely.

The iron rod 202 has a diameter of 4 mm and a length of 22 mm. There is a space of 6 mm between the first bushing 206 and the second bushing 208 of the same iron rod 202 to ensure that the two can rotate freely on the iron rod 202 . The length of the threaded structure 203 is 4mm. This design is to make the iron rod as short as possible, so as not to be affected by the protrusion of the roof of the roadway outside the cylinder or the impact of gravel; the outer diameter of the first sleeve 206 and the second sleeve 208 is 7mm , the inner diameter is 6mm, and the length is 6mm; the diameter of the first connecting rod 205 and the second connecting rod 207 is 5mm, and the length is 10mm larger than the diameter of the cylindrical roller 201, and the outer diameter of the fixing nut 204 is 10mm, and the inner diameter is 4mm. The diameter is as small as possible, so that the roadway roof protrusions or gravel do not touch the iron rod 202 as much as possible, because the biggest innovation of the design of the cylindrical pressure-bearing row 2 is to convert all the huge upper pressure into cylindrical rollers 201 to bear , The iron rods 202 only bear their rotation. If the middle of the cylinder is designed with bearings, the huge pressure on the top plate will cause the bearings to fail and fail to function. Therefore, the iron rod 202 that does not bear pressure should be as short as possible, so as to avoid damage to the iron rod 202 caused by the protrusion of the roadway roof 3 outside the cylindrical roller 201, and it is too short to fully play its role, so the design of this size is relatively reasonable. , the size of the present invention is a preferred design, not necessary, and does not form a limit to the scope of protection, but the effect is better in this way.

The function of the strip-type holding funnel 5 is mainly to store some of the stacked cylindrical pressure-bearing rows 2, so that when the frame is moved, the cylindrical pressure-bearing row 2 rolls into the roadway roof 3 and the roof beam along the front roof beam guard plate. , without the need for manual care and work.

The height of the strip-type holding funnel 5 is 490mm, the width is 450mm, and the length is 480mm; the main purpose is to ensure that the funnel has a certain space to hold the cylindrical pressure-bearing row, and at the same time ensure that the torque will not be too large. The strength bears the pressure brought by the cylindrical pressure row.

The "spoon handle" of the bar-type holding funnel 5, that is, the maximum inclination angle of the arc-shaped connection part 502 is close to 80°, and then it is smoothly connected with the plate-type pressure-bearing baffle 4, and the two are welded. The reason for this design is Roadway roof 3 will regularly scatter some crushed stones and coal gangue etc., such angle and strip shape can allow crushed stones etc. to roll into strip type holding funnel 5 li, can fall to the roadway floor at last, steel bar welding can also The strength requirement is guaranteed, and the ventilation wind resistance is reduced at the same time, ensuring the ventilation volume of the roadway section. This is not necessary, it is the preferred design, and the effect is better.

The plate type pressure baffle 4 comprises a pressure plate, a pressure block 403 and a first fixed plate 404, the pressure block 403 is a solid square iron block, and its function is mainly to carry the forward driving force of the top beam of the support, and then drive the plate type pressure Plate 4 and bar type holding funnel 5 move thereupon.
