Description

Technical Field

[0001] This application relates to the field of blasting technology, and in particular to a slope blasting construction method. Background Art

[0002] Slope blasting means setting blasting holes on the slope surface of the blasting target body, then setting explosives in the blasting holes, and then detonating the explosives to blast the blasting target body.

[0003] Regarding the above related technology, the inventor believes that the working surface where the blasting holes are located is an inclined plane, and it is difficult for construction workers to work on the inclined plane, which in turn makes it difficult to accurately drill the blasting holes. Summary of the Invention

[0004] In order to set the blasting holes more efficiently and accurately, this application provides a slope blasting construction method.

[0005] A slope blasting construction method provided by this application adopts the following technical solution: Construction is carried out using a positioning device.

[0006] The positioning device includes:

[0007] A fixing member, which is arranged at the top of the slope of the target body and is used for anchoring the positioning device;

[0008] A winding vehicle, which is located at the lower end of the slope of the target body and can move closer to or away from the fixing member on the slope of the target body;

[0009] A positioning net, which connects the winding vehicle and the fixing member. The positioning net is laid on the slope surface, and positioning rings are arranged on the positioning net;

[0010] A winder, which is arranged on the winding vehicle and is used for winding the positioning net;

[0011] It includes the following steps:

[0012] Step 1: Set the positioning device at the top of the slope of the target body;

[0013] Step 2: Let the winding vehicle drive downward along the slope, and at the same time start the winder to unwind the positioning net;

[0014] Step 3: Construction workers climb on the slope using the positioning net;

[0015] Step 4: Let the drilling equipment pass through the positioning ring to drill blasting holes on the slope;

[0016] Step 5: Fill the blasting holes with explosives;

[0017] Step 6: Construction workers climb and evacuate from the slope on the positioning net;

[0018] Step Seven: Drive the rewinding vehicle to travel upward along the slope, and at the same time start the rewinder to wind the positioning net.

[0019] Step Eight: Detonate the explosive to blast the target.

[0020] By adopting the above technical solution, the positioning net laid on the slope of the target can not only be used to facilitate the climbing of operators, but also the positioning rings on the positioning net can accurately position the drilling, so as to facilitate the accurate drilling of the blasting holes.

[0021] In addition, the winding of the positioning net is automatically realized by the rewinding vehicle, which improves the efficiency of laying and winding the positioning net.

[0022] Optionally: The rewinder includes a winding roller and a driving source. The positioning net connects the winding roller and the fixing member. The driving source is connected to one end of the winding roller. The driving source is arranged on the rewinding vehicle. The other end of the winding roller is rotatably connected to the rewinding vehicle. There is a gap between the winding roller and the slope of the target.

[0023] By adopting the above technical solution, the driving source drives the winding roller to rotate, so as to realize the winding and unwinding of the positioning net, which is convenient for the laying and recovery of the positioning net.

[0024] Optionally: An arc-shaped pressing member is connected between the winding roller and the positioning net. The pressing member is in a semi-circular ring shape. One end of the pressing member in the arc length direction is rotatably connected to the winding roller. The other end of the pressing member in the arc length direction abuts against the slope of the target and is connected to the positioning net.

[0025] By adopting the above technical solution, in order to prevent the positioning net from touching the slope during the winding and laying process, there is a large gap between the winding roller and the slope. However, this will cause a large distance between the end of the positioning net connected to the winding roller and the slope in the finally spread state, which is not conducive to the drilling work.

[0026] By setting the pressing member, when the positioning net is wound on the winding roller, the pressing member fits the surface of the winding roller.

[0027] When the positioning net is fully unfolded, the pressing member is between the winding roller and the positioning net. At this time, there is a certain distance between the end of the winding roller connected to the positioning net and the slope.

[0028] Then, continue to rotate the winding roller in the clockwise direction of unwinding and laying the positioning net, so that the end of the pressing member connected to the positioning net abuts against the slope, and then the positioning net fits the slope.

[0029] Optionally: There are two rewinding vehicles. One is rotatably connected to one end of the winding roller, and the other is connected to the driving source.

[0030] By adopting the above technical solution, two winding vehicles are provided, which can have better power. Even if one of the winding vehicles is damaged, the other can still keep running, so as to realize the winding of the positioning net.

[0031] Optionally, a synchronizing rod is connected between the two winding vehicles.

[0032] By adopting the above technical solution, both ends of the synchronizing rod are respectively connected to a winding vehicle, so that the two winding vehicles can have better synchronism when driving along the slope.

[0033] Optionally, a connecting ring is arranged at one end of the pressing member connected to the positioning net, and a connecting ring is arranged at one end of the fixing member connected to the positioning net. Hook members are arranged at both ends of the positioning net, and the hook members are connected to the corresponding connecting rings.

[0034] By adopting the above technical solution, the positioning net can be detachably connected to both the winding roller and the fixing member, which is convenient for replacing the positioning net. When the positioning net is damaged or when it is necessary to lay out drill holes with different spacings on the slope, the positioning net with different-spacing positioning rings can be replaced to meet the requirements.

[0035] Optionally, the fixing member includes a traveling vehicle, the positioning net is connected to the traveling vehicle, and a locking assembly for fixing to the target body is arranged on the traveling vehicle.

[0036] By adopting the above technical solution, after the traveling vehicle is fixed on the top of the slope through the locking assembly, when the winding vehicle moves down the slope to the lowest position, the positioning net can be tensioned tightly and is not easy to shake.

[0037] Optionally, the locking assembly includes a track and a locking rod. The locking rod is perpendicular to the track and is screwed on the traveling vehicle. The traveling vehicle is slidably connected to the track, and a locking hole for the locking rod to penetrate is arranged on the track.

[0038] By adopting the above technical solution, rotating the locking rod can control the locking rod to enter or exit the locking hole. When the locking rod enters the locking hole, the traveling vehicle is blocked and cannot move along the length direction of the track. Therefore, by operating the locking rod, it can be controlled whether to lock the traveling vehicle on the track.

[0039] Optionally, the track includes a plurality of unit segments arranged in sequence. Adjacent unit segments are in contact with each other, and an anchor rod is connected to the unit segment, and the anchor rod is inserted into the target body.

[0040] By adopting the above technical solution, the segmented unit segments facilitate the disassembly and installation of the track.

[0041] In summary, the present application has the following beneficial effects:

[0042] 1. The positioning net laid on the slope of the target body can not only facilitate the climbing of operators, but also the positioning rings on the positioning net can accurately position the drilling, thus facilitating the accurate drilling of blasting holes;

[0043] 2. The winding of the positioning net is realized by the winding vehicle for automatic winding, which improves the efficiency of laying and winding the positioning net;

[0044] 3. By setting the tightening member, the winding roller is rotated in the clockwise direction of unwinding and laying the positioning net, so that one end of the tightening member connected to the positioning net abuts against the slope surface, thereby realizing the positioning net fitting the slope surface.

[0051] The following further describes the present application in detail Figures 1-4 in conjunction with the attached drawings.

[0052] As Figure 1 shown, it is a slope blasting construction method disclosed in the present application, which uses the positioning device 1 for construction. The positioning device 1 includes a fixing mechanism 21, a winding mechanism 23 and a positioning net 7. The positioning net 7 connects the fixing mechanism 21 and the winding mechanism 23, and the positioning net 7 is used to fit on the slope surface 6 of the blasting target body 4.

[0053] As Figure 1 , 2As shown in the figure, the winding mechanism 23 includes a winding cart 3 and a winder 9. There are two winding carts 3, and both ends of the winder 9 are respectively connected to the two winding carts 3.

[0054] The winder 9 includes a winding roller 10 and a driving source 11. The driving source 11 is a motor. The positioning net 7 is connected to the winding roller 10 and the fixing mechanism 21. The output shaft of the driving source 11 is coaxially connected to one end of the winding roller 10. The driving source 11 is installed on one of the winding carts 3, and the other end of the winding roller 10 is rotatably connected to the other winding cart 3. There is a gap between the winding roller 10 and the slope 6 of the target body 4 to be subjected to blasting. When the positioning net 7 is wound on the winding roller 10, there is still a gap between the positioning net 7 and the slope 6. By driving the winding roller 10 to rotate through the driving source 11, the positioning net 7 can be wound or unwound.

[0055] The winding cart 3 is equipped with a driving mechanism by itself, so that the winding cart 3 can move upward or downward along the slope 6. The two winding carts 3 are connected by a synchronizing rod 13, so that the two winding carts 3 can move synchronously better. Since two winding carts 3 are provided, better power can be provided. Even if one of the winding carts 3 is damaged, the other winding cart 3 can still keep running.

[0056] Before drilling the slope 6, the positioning device 1 is integrally set on the top of the slope 5, and then the winding cart 3 is made to travel downward along the slope 6, and at the same time, the driving source 11 of the winder 9 is started to drive the winding roller 10 to rotate, so as to start unwinding the positioning net 7. When the winding cart 3 travels to the bottom of the slope, the positioning net 7 is laid out.

[0057] Because there is a large gap between the winding roller 10 and the slope 6, this will cause the end of the positioning net 7 connected to the winding roller 10 in the finally laid-out state to be at a large distance from the slope 6, so that the positioning net 7 is difficult to fit the slope 6 and is not conducive to the subsequent drilling work.

[0058] As Figure 1 、 2 shown, in order to make the positioning net 7 fit the slope 6 more closely, an arc-shaped pressing member 12 is connected between the winding roller 10 and the positioning net 7. The pressing member 12 is in a semi-circular ring shape. One end in the arc length direction of the pressing member 12 is rotatably connected to the winding roller 10, and the other end in the arc length direction of the pressing member 12 is connected to the positioning net 7.

[0059] By using the pressing member 12, when the positioning net 7 is wound on the winding roller 10, the pressing member 12 fits the surface of the winding roller 10 and is wrapped by the wound positioning net 7.

[0060] When the positioning net 7 is fully deployed, the pressing member 12 is located between the winding roller 10 and the positioning net 7. At this time, there is a certain distance between the winding roller 10 connected to one end of the positioning net 7 and the slope 6. In this state, the positioning net 7 also maintains a certain distance from the slope 6.

[0061] Next, the winding roller 10 is rotated in the clockwise direction of unwinding and laying the positioning net 7, so that one end of the pressing member 12 connected to the positioning net 7 abuts against the slope 6. In addition, the fixing mechanism 21 is arranged at the edge away from the top of the slope 5, so that the upper end of the positioning net 7 also fits against the slope 6, thereby realizing the overall fitting of the positioning net 7 to the slope 6.

[0062] A plurality of positioning rings 8 are distributed at intervals on the positioning net 7 as required. After the positioning net 7 is laid on the slope 6, a drilling device is made to pass through the positioning rings 8 to drill blasting holes on the slope 6, which can overcome the disadvantages of inconvenient and inaccurate drilling and lofting on the slope 6.

[0063] As Figure 1 、 3 shown, the fixing mechanism 21 includes a fixing member 2 and a locking assembly 17. The fixing member 2 includes a traveling vehicle 16, and the positioning net 7 is connected to the traveling vehicle 16. The locking assembly 17 includes a track 18 and a locking rod 19.

[0064] The track 18 is arranged perpendicular to the edge of the top of the slope 5. The track 18 is at a certain distance from the edge of the top of the slope 5 and extends in a position away from the edge of the top of the slope 5. Two tracks 18 are arranged in parallel with each other, and the distance between the two tracks 18 is greater than the width of the positioning net 7. One end of the positioning net 7 is connected to the traveling vehicle 16, and wheels are rotatably connected to both ends of the traveling vehicle 16, and the wheels of the traveling vehicle 16 are in rolling connection with the track 18.

[0065] The track 18 includes a plurality of unit segments 24 arranged in sequence. The adjacent unit segments 24 abut against each other, and an anchor rod 25 inserted into the target body is connected to the lower part of the unit segment 24. The segmented unit ends 24 facilitate the disassembly and installation of the track 18.

[0066] As Figure 2 、 3As shown in the figure, a connecting plate 22 is fixed at the position where the walking vehicle 16 is above the track 18. The locking rod 19 passes through and is screwed onto the connecting plate 22. In addition, the locking rod 19 is perpendicular to the track 18, and a locking hole 20 for the locking rod 19 to penetrate is provided on the track 18. A plurality of locking holes 20 are equidistantly distributed along the length direction of the track 18. By rotating the locking rod 19, it can be controlled whether the locking rod 19 enters or exits the locking hole 20. When the locking rod 19 enters the locking hole 20, the walking vehicle 16 cannot move along the length direction of the track 18, thereby controlling whether to lock the walking vehicle 16 on the track 18. After the slope 6 of the target body 4 is blasted, the walking vehicle 16 can be pushed to move along the track 18, then fixed, and then the winding mechanism 23 is operated to lay the positioning net 7, and then drilling and lofting are carried out on the slope 6 again.

[0067] As Figure 1 , 4 shown, a connecting ring 14 is fixed at one end of the pressing member 12 connected to the positioning net 7, and a connecting ring 14 is also fixed at one end of the fixing member 2 connected to the positioning net 7. Hook members 15 are fixed at both ends of the positioning net 7, and the hook members 15 are connected to the corresponding connecting rings 14.

[0068] Through the above settings, the positioning net 7 can be detachably connected to both the pressing member 12 and the fixing member 2. When it is necessary to loft holes with different spacings on the slope 6, the positioning net 7 with positioning rings 8 of different spacings can be replaced to meet the requirements.

[0069] The blasting construction method using the positioning device 1 includes the following steps:

[0070] Step 1: Set the positioning device 1 at the top of the slope 5 of the target body 4.

[0071] 1. Lay the unit section 24, and insert the anchor bolts 25 on the unit section 24 into the target body 4, so as to splice the unit sections 24 to form the track 18, and make the track 18 at a certain distance from the edge of the top of the slope 5 of the target body 4;

[0072] 2. Control the locking rod 19 to enter the locking hole 20 by rotating the locking rod 19, so as to fix the walking vehicle 16 on the track 18. The walking vehicle 16 is arranged away from the edge of the top of the slope 5, so that the upper end of the positioning net 7 also fits the slope 6.

[0073] Step 2: Lay the positioning net 7.

[0074] 1. Let the winding vehicle 3 drive downward along the slope 6, and at the same time start the driving source 11 of the winder 9, and drive the winding roller 10 to rotate, so as to start unwinding the positioning net 7 until the positioning net 7 is completely unfolded;

[0075] 2. Rotate the take-up roller 10 further in the clockwise direction of laying the positioning net 7 to the unwinding side, so that one end of the pressing member 12 connected to the positioning net 7 abuts on the slope 6, thereby realizing the positioning net 7 fitting on the slope 6.

[0076] Step 3: The construction workers climb on the slope 6 by using the positioning net 7;

[0077] Step 4: Operate the drilling equipment to drill blasting holes on the slope 6 through the positioning ring 8;

[0078] Step 5: Fill the blasting holes with explosives;

[0079] Step 6: The construction workers climb and evacuate from the slope 6 on the positioning net 7;

[0080] Step 7: Drive the take-up vehicle 3 to travel upward along the slope 6, and at the same time start the take-up device 9 to take up the positioning net 7;

[0081] Step 8: Detonate the explosives to blast the target body 4;

[0082] Step 9:

[0083] 1. After the slope 6 of the target body 4 is blasted, remove the unit section 24 near the edge of the slope top 5, and push the walking vehicle 16 to move along the track 18 in the direction away from the edge of the slope top 5;

[0084] 2. Fix the walking vehicle 16 on the track 18 again through the locking assembly 17;

[0085] 3. Operate the take-up mechanism 23 to lay the positioning net 7, and then carry out drilling and lofting on the slope 6 again.

[0086] In summary, by laying the positioning net 7 on the slope 6 of the target body 4, it can not only be used to facilitate the climbing of the operators, but also the positioning ring 8 on the positioning net 7 can accurately position the drilling, avoiding the problem that it is difficult for the construction workers to carry out drilling operations on the inclined slope 6, and facilitating the accurate drilling of the blasting holes.

[0087] In addition, the take-up of the positioning net 7 is realized automatically through the take-up vehicle 3, improving the efficiency of laying and taking up the positioning net 7.

[0088] The embodiments of the specific implementation manners are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
