Description

Technical Field

[0001] The present invention relates to the field of energy-saving mining machinery, and specifically to a vehicle-mounted rotary drilling and boring integrated machine. Background Art

[0002] During the process of mine exploitation, drilling is a very important technical means, which is usually used in multiple links such as mine exploration, exploitation, ventilation, and drainage. Among them, in the exploration link, information such as the geological structure, ore body distribution, and ore grade of the mine can be understood, which helps the subsequent development and utilization of mine resources.

[0003] During the drilling process in the exploration link, the operation of usually drilling one meter in advance is generally called "pre-drilling" or "pilot hole". This operation is very common in the actual drilling process and is mainly used to ensure that the drill bit can smoothly enter the formation, and at the same time provide a stable starting point for the subsequent deep drilling operation. At the same time, in some loose or unstable formations, drilling one meter in advance can prevent the wellhead from collapsing, ensure the stability of the wellhead, and contribute to the smooth progress of the subsequent drilling operation.

[0004] However, the current pre-drilling operation usually relies on drilling equipment, that is, first pre-drill through the drilling equipment and then perform deep drilling. The drilling equipment itself is large in size and the length of a single drill pipe is relatively large. During pre-drilling, the center of gravity of the drill pipe is relatively high and the stability is poor, resulting in difficult pre-drilling. Especially when encountering some hard ore layer surfaces, the downward pushing speed of the drill pipe is slower, resulting in slower drilling efficiency. And in the case of encountering loose formations, the heavy drilling equipment is prone to collapse into the loose formation during pre-drilling and it is difficult to get out later. The above problems will consume more resources and do not conform to the advocated construction of green and energy-saving mines.

Detailed implementation manners

[0040] In order to make the technical means, creative features, achieved purposes and functions realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0041] Refer to Figures 1-4 and Figures 9-13 A vehicle-mounted rotary drilling integrated machine includes a flatbed truck 1 towed and moved by a tractor. A towing rod 2 is arranged at the front end of the flatbed truck 1. A pre-drilling unit is arranged at a position near the rear in the flatbed truck 1. The pre-drilling unit includes a base plate 3 arranged on the inner bottom plate of the flatbed truck 1. The position of the base plate 3 near the front end of the flatbed truck 1 is rotatably connected to the inner bottom plate of the flatbed truck 1.

[0042] A plurality of rotating shafts 4 are arranged in a circumferential array on the upper surface of the base plate 3. The lower ends of the rotating shafts 4 are rotatably connected to the base plate 3. A first lead screw 5 is arranged at the upper end of the rotating shaft 4. The upper ends of the plurality of first lead screws 5 are jointly rotatably connected to a top plate 6. A lifting plate 7 is arranged below the top plate 6. The lifting plate 7 is threadedly connected to the first lead screw 5. A drilling motor 8 is arranged on the lifting plate 7. The output end of the drilling motor 8 is fixedly connected to a drill rod 9. The lower end of the drill rod 9 is fixedly connected to a drill bit 10. A relief hole 11 is opened at a position on the inner bottom plate of the flatbed truck 1 opposite to the drill bit 10.

[0043] In this embodiment, the designed vehicle-mounted rotary drilling integrated machine is used to pre-drill a pilot hole on the surface layer of a mine. The vehicle-mounted rotary drilling integrated machine mainly consists of a flatbed truck 1 and a pre-drilling unit. A plurality of towing rods 2 are arranged at the front end of the flatbed truck 1. As shown in the figure, the towing rods 2 are distributed on both sides and the middle position at the front end of the flatbed truck 1. The tractor towing the flatbed truck 1 can be a coal mine transport vehicle. The coal mine transport vehicle and the flatbed truck 1 are tied together by a steel wire rope. The flatbed truck 1 together with the pre-drilling unit is towed to the drilling site by the coal mine transport vehicle. Then, the steel wire rope is loosened and separated from the coal mine transport vehicle. As for the subsequent movement of the flatbed truck 1, it can be pushed manually.

[0044] In the vehicle-mounted rotary drilling integrated machine designed in this embodiment, the overall length of the flatbed truck 1 is 2.5 - 4 meters, the width is 1.5 - 2 meters, and the height of the pre-drilling unit is controlled at 1.8 - 2 meters. The drill rod 9 and the drill bit 10 can drill a depth of 0.8 - 1.2 meters. Compared with the existing drilling equipment, the overall volume is smaller, the mass is lighter, and it is more flexible. It can be pushed manually by multiple operators in cooperation, or the wheels of the flatbed truck 1 can be replaced with wheels driven by hub motors, and the flatbed truck 1 can be driven by electricity to adjust the position of the flatbed truck 1 and the drilling point.

[0045] The lower end of the rotating shaft 4 is connected to a reduction motor 12 that drives its rotation. The reduction motor 12 is arranged on the base plate 3, and the reduction motor 12 can drive the rotating shaft 4 to rotate. The rotating shaft 4 drives the first lead screw 5 to rotate, and the first lead screw 5 drives the lifting plate 7 to move up and down.

[0046] The vehicle-mounted rotary drilling machine is specifically operated as follows: the trolley 1 is moved to the pre-drilling position so that the clearance hole 11 on the trolley 1 is opposite to the pre-drilling position, and then the drilling motor 8 is driven to drive the drill rod 9 to rotate the rod 29, and the drill rod 9 drives the drill bit 10 to rotate, and then the reduction motor 12 is driven to drive the rotating shaft 4 to rotate, and the first screw rod 5 drives the lifting plate 7 to move down, and the drill bit 10 touches the mine surface and drills holes on the surface. Since the entire vehicle-mounted rotary drilling machine is small in size and the drill rod 9 is short, the center of gravity of the entire pre-drilling unit is low. During the pre-drilling process, the operation is stable, and the lead hole can be drilled quickly with high efficiency. At the same time, for some harder mineral layer surfaces, the pre-drilling unit can also drill holes stably, and in the case of encountering some loose strata, even if it is trapped in the soil layer, it can be easily escaped, reducing the consumption of manpower, material resources and financial resources.

[0047] Drilling construction in mines, and there is not only one drilling point. Generally, multiple drilling points are planned at one time in the mine, and each drilling point is pre-drilled by the vehicle-mounted rotary drilling machine to drill the lead hole, which can improve the overall drilling operation efficiency;

[0048] As shown in the figure, a rotation groove 13 is symmetrically opened on the base plate 3 near the front end of the cart 1, and a ring-shaped connector 14 is rotatably connected in the rotation groove 13. The connector 14 is externally connected to the inner bottom plate of the cart 1. When the vehicle-mounted rotary drilling machine needs to move a long distance, the pre-drilling unit can be rotated and dumped and placed in the cart 1, the base plate 3 rotates around the connector 14, and the entire pre-drilling unit is dumped and placed on the inner bottom plate of the cart 1, and then it can be fixed, thereby further lowering the center of gravity of the pre-drilling unit. Even in a bumpy road section, the pre-drilling unit can still be stable in the cart 1 to prevent the cart 1 from moving violently and swinging, causing the cart 1 to overturn.

[0049] Reference Figures 9-13 , the fixing plates 15 are symmetrically arranged on both sides of the base plate 3, and a second screw rod 16 and a sliding rod 17 are arranged between the two fixing plates 15;

[0050] Both ends of the second screw rod 16 are rotatably connected to the fixed plate 15. The second screw rod 16 is arranged close to the front end of the cart 1. The second screw rod 16 is threadedly connected and passes through the front side of the base plate 3.

[0051] Both ends of the slide bar 17 are fixed to the fixed plate 15. The slide bar 17 is arranged near the rear end of the cart 1. A strip-shaped slide groove 18 is provided at the rear bottom of the base plate 3. The slide bar 17 is slidably connected in the slide groove 18.

[0052] The forward and backward movement of the trolley 1 can adjust the forward and backward position adjustment of the drill bit 10 and the drilling point, and the second screw rod 16 drives the base plate 3 to move left and right in the trolley 1, which can adjust the left and right position adjustment of the drill bit 10 and the drilling point, so that the drill bit 10 and the drilling point are accurately opposite;

[0053] As for the second lead screw 16 driving the substrate 3 to move left and right, the specific operation is as follows: Through holes 19 are opened on both sides of the flatbed truck 1, and the through holes 19 are opposite to the ends of the second lead screw 16. Grooves 20 are opened on the fixing plate 15 for rotatably connecting with the second lead screw 16. The ends of the second lead screw 16 are arranged in a hexagonal prism shape, and the ends of the second lead screw 16 extend into the grooves 20. At this time, a socket wrench can be used to penetrate through the through hole 19 into the flatbed truck 1, and then the end of the socket wrench penetrates into the groove 20 and is sleeved on the end of the second lead screw 16. Rotate the second lead screw 16 to rotate, and the second lead screw 16 drives the substrate 3 to move between the two fixing plates 15 to adjust the position of the drill bit 10. The chute 18 arranged at the rear side of the substrate 3 cooperates with the slide bar 17 to further stabilize the entire pre-drilling unit, so that when the position is adjusted, the substrate 3 can move smoothly along the inner bottom plate of the flatbed truck 1;

[0054] The substrate 3 moves between the two fixing plates 15. At the same time, a strip-shaped hole 21 for the connecting body 14 to move is arranged on the inner bottom plate of the flatbed truck 1. The connecting body 14 is slidably connected in the strip-shaped hole 21 and can move along with the movement of the substrate 3.

[0055] Refer to Figure 1 、 Figure 4 、 Figure 5 and Figure 6 as well as Figures 9-12 , a buffer assembly is arranged at the front position in the flatbed truck 1. The buffer assembly includes a support plate 22 and a plurality of springs 23;

[0056] The support plate 22 is inclined in the flatbed truck 1. The lower end of the support plate 22 is close to the front side of the substrate 3, and the upper end position of the support plate 22 is close to the front end of the flatbed truck 1. A plurality of springs 23 are fixedly connected to the lower surface of the support plate 22, and the end of each spring 23 is fixedly connected to the inner bottom plate of the flatbed truck 1;

[0057] The entire pre-drilling unit is placed in the flatbed truck 1 in a tilted state. Considering the vibration damage to the pre-drilling unit caused by the vibration generated during the movement of the flatbed truck, a buffer assembly is arranged in the flatbed truck 1, and the pre-drilling unit is elastically supported on the inner bottom plate of the flatbed truck 1. Through the deformation of the support plate 22 and the elastic support of the springs 23, the vibration is slowed down and the vibration damage to the pre-drilling unit is reduced. Moreover, after the pre-drilling unit is placed in the flatbed truck 1 in a tilted state, the center of gravity of the entire flatbed truck 1 is concentrated on its front side. When the flatbed truck 1 is towed by a tractor later, the stability of the flatbed truck 1 moving on the ground can be improved, and the wagging phenomenon of the flatbed truck 1 can be reduced. Furthermore, the entire pre-drilling unit is not placed horizontally in the flatbed truck 1 but in an inclined state. When the pre-drilling unit is rotated and lifted later, compared with the case where the entire pre-drilling unit is placed horizontally in the flatbed truck 1, the pre-drilling unit in an inclined state is easier to rotate and lift, reducing labor.

[0058] Refer toFigure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 8 and Figure 12 , a cross bar 24 is provided at the rear end of the flatbed cart 1, and a fixing component is provided between the cross bar 24 and the top plate 6. The fixing component is used to vertically and stably hold the pre-drilling unit in the flatbed cart 1, and the fixing component includes a first hook body 25, a second hook body 26, a screw 27, a threaded cylinder 28 and a rotating rod 29; one end of the rotating rod 29 is fixedly connected to the first hook body 25, the first hook body 25 is hooked on the cross bar 24, the other end of the rotating rod 29 is rotatably connected to one end of the threaded cylinder 28, the other end of the threaded cylinder 28 is threadedly connected to one end of the screw 27, and the other end of the screw 27 is fixedly connected with a second hook body 26, and the second hook body 26 is hooked on a hanging rod 30 provided on the top plate 6;

[0059] After the pre-drilling unit is rotated and lifted, the position of the drill bit 10 is adjusted by the second lead screw 16, and then the fixing component is installed. The whole pre-drilling unit is stabilized by the fixing component. The specific operation is as follows: First, hook the second hook body 26 on the hanging rod 30, then hook the first hook body 25 on the cross bar 24, and then rotate the threaded cylinder 28 for the threaded cylinder 28 to be threadedly connected with the screw 27. When the threaded cylinder 28 is rotated, the screw 27 is gradually tightened, and the whole fixing component gradually tightens the pre-drilling unit and the cross bar 24, further stabilizing the pre-drilling unit on the flatbed cart 1 and improving the stability of the pre-drilling unit during operation;

[0060] This fixing component can not only stabilize the pre-drilling unit during operation, but also stabilize it after it is tilted and placed on the support plate 22. Specifically, as shown in the figure, a reinforcing bar 31 is provided on the front side inside the flatbed cart 1. After the pre-drilling unit is tilted and placed on the support plate 22, hook the first hook body 25 and the second hook body 26 on the reinforcing bars 31 on both sides respectively, and the middle position of the fixing component presses on the pre-drilling unit. Then rotate the threaded cylinder 28, the first hook body 25 and the second hook body 26 are tightened and fixed on the reinforcing bar 31, and the pre-drilling unit is pressed on the support plate 22. Subsequently, the pre-drilling unit is protected by the elastic buffer of the spring 23.

[0061] Refer to Figure 8 , an auxiliary component is provided between the threaded cylinder 28 and the rotating rod 29. The auxiliary component is used to fix the threaded cylinder 28, and the auxiliary component includes a plug rod 32 penetrating through the threaded cylinder 28. One end of the plug rod 32 is rotatably connected with a handle 33, and a clamping plate 34 is provided on the outer ring of the end of the handle 33. The clamping plate 34 is clamped on a clamping block 35 provided on the outer ring of the rotating rod 29;

[0062] Push the handle 33. The handle 33 drives the threaded cylinder 28 to rotate around the axis of the screw rod 27 through the insertion rod 32. The threaded cylinder 28 tightens the screw rod 27, fastening the pre-drilling unit and the cross bar 24 together. Then rotate the handle 33 so that the handle 33 rotates around its rotational connection with the insertion rod 32, making the mouth of the clamping plate 34 on the clamping block 35 on the outer circle of the rotating rod 29. At this time, the clamping plate 34 and the clamping block 35 are fixed together, thus restricting the relative rotation between the threaded cylinder 28 and the screw rod 27, and also restricting the overall length of the fixing assembly, thereby stably fastening the pre-drilling unit and the cross bar 24 together. Moreover, this auxiliary assembly can not only restrict the overall length of the fixing assembly, but also provide convenience for the rotation of the threaded cylinder 28. Push the handle 33, using the handle 33 as a tool to drive the rotation of the threaded cylinder 28, facilitating the rotation of the threaded cylinder 28.

[0063] Refer to Figure 6 and Figure 8 There is an anti-slip strip 36 on the inner circle of the first hook body 25; a plurality of annular bodies 37 are evenly arranged on the outer circle of the cross bar 24. The first hook body 25 hooks on the cross bar 24, and the anti-slip strip 36 and the annular bodies 37 are engaged with each other;

[0064] When the pre-drilling unit operates, the generated vibration force will cause the first hook body 25 and the cross bar 24 to slide relatively. The provided anti-slip strip 36 and annular bodies 37 can restrict the relative sliding trend between the first hook body 25 and the cross bar 24, improving the connection stability between the fixing assembly and the cross bar 24.

[0065] Refer to Figure 2 、 Figure 3 、 Figure 6 and Figure 7 There is a braking assembly at the bottom of the flatbed cart 1. The braking assembly is used to stabilize the flatbed cart 1 on the ground, and the braking assembly includes a brake disc 38, a cross plate 39 and a fastening bolt 40;

[0066] The brake disc 38 is coaxially and fixedly connected to the connecting shaft 41 of the wheel of the flatbed cart 1;

[0067] The upper edge of the cross plate 39 is slidably connected to the bottom of the flatbed cart 1. A plurality of extrusion holes 42 are opened on the cross plate 39. The extrusion holes 42 are sleeved on the outer circle of the brake disc 38. One end of the cross plate 39 extends to the rear end position of the flatbed cart 1, and one end of the cross plate 39 is rotatably connected to the flatbed cart 1 through the fastening bolt 40;

[0068] When the on-vehicle rotary drilling integrated machine is pre-drilling on a slope, the on-vehicle rotary drilling integrated machine will move automatically along the trend of the slope. Therefore, a braking component is provided on the flatbed truck 1. After the position of the flatbed truck 1 is adjusted, the braking component is then operated. Specifically, a fixed ear 43 is welded on one side of the rear end of the flatbed truck 1. A fastening bolt 40 is rotatably connected to the fixed ear 43. The end of the fastening bolt 40 is threadedly connected to the cross plate 39. By rotating the fastening bolt 40, the cross plate 39 can be moved in the front-back direction of the flatbed truck 1. When the cross plate 39 moves towards the rear side of the flatbed truck 1, the extrusion hole 42 will squeeze against the brake disc 38, stabilizing the brake disc 38, thereby stabilizing the wheels, and then stabilizing the entire on-vehicle rotary drilling integrated machine, ensuring that the pre-drilling unit can perform pre-drilling operations stably and accurately at the drilling point.

[0069] Refer to Figure 7 , a trigger component for controlling the power-on of the pre-drilling unit is provided on the inner bottom plate of the flatbed truck 1. The trigger component includes an end shell 44 provided on the inner bottom plate of the flatbed truck 1. A trigger switch 45 is provided inside the end shell 44. One side of the contact of the trigger switch 45 is provided with an extrusion block 46. The extrusion block 46 passes through a sliding hole 47 opened on the inner bottom plate of the flatbed truck 1 and is fixedly connected to the cross plate 39;

[0070] The provided trigger component is used to control the connection and disconnection of the power supplies of the drilling motor 8 and the reduction motor 12, and the trigger component cooperates with the braking component to execute. That is, only after the flatbed truck 1 is stable can the pre-drilling component execute. Specifically, the cross plate 39 moves towards the rear side of the flatbed truck 1, and at the same time, the cross plate 39 drives the extrusion block 46 to squeeze the trigger switch 45. The trigger switch 45 is connected to the power supply wires of the drilling motor 8 and the reduction motor 12. When the trigger switch 45 is squeezed by the extrusion block 46, the power supply wires are connected together. At this time, the power supplies of the drilling motor 8 and the reduction motor 12 are also connected to the power supply. As for the rotation speed and direction of the drilling motor 8 and the reduction motor 12, they can be controlled by the PLC; the trigger component cooperates with the braking component to execute, endowing the on-vehicle rotary drilling integrated machine with a safe execution logic and improving its use safety.

[0071] Refer to Figure 9 and Figure 13 , the lower surface of the lifting plate 7 is symmetrically provided with ejector rods 48. The two ejector rods 48 are arranged on both sides of the drill rod 9. A restraint plate 49 is provided below the ejector rods 48. The restraint plate 49 is provided with a rotating hole 50. The drill rod 9 passes through the hole for drilling. And the lower surfaces on both sides of the restraint plate 49 are provided with return springs 51. The ends of the return springs 51 are fixedly connected to the upper surface of the base plate 3;

[0072] The drill rod 9 passes through the rotating hole 50 on the constraint plate 49, which can constrain the radial swing amplitude of the drill rod 9 and improve the stability of the drill rod 9 and the drill bit 10 during the drilling process. When the lifting plate 7 gradually moves downward, the lower end of the push rod 48 will press down the constraint plate 49, so that the constraint plate 49 moves downward synchronously with the drill rod 9, so that the constraint plate 49 remains in the middle area of the drill rod 9. The upper end of the drill rod 9 is constrained by the drilling motor 8, and the lower end of the drill rod 9 is connected to the drill bit 10. The drill bit 10 is constrained by the side wall of the borehole, and the middle of the drill rod 9 is constrained by the constraint plate 49, thereby improving the operating stability of the drill rod 9.

[0073] Reference Figure 9 and Figure 12 , a plurality of vertical water pipes 52 are arranged on the restraining plate 49, and the ends of the water pipes 52 penetrate the base plate 3 and extend toward the ground;

[0074] A plurality of water spray holes are provided on the outer wall of the water pipe 52, and the water spray holes are arranged along the length direction of the water pipe 52. The water pipe 52 is connected to an external water pump through a hose, and the water pump pumps water into the water pipe 52, and the water is discharged from the water spray holes. When the drill bit 10 is not in use or after use, the water can be used to wash the surface of the drill bit 10 to clean the alkaline or acidic substances attached to the surface, so as to wash and protect the drill bit 10. When the drill bit 10 is in use, intense friction will be generated between the drill bit 10 and the rock and other media, generating a large amount of heat. If the heat cannot be dissipated in time, the temperature of the drill bit 10 will rise sharply. When the temperature of the drill bit 10 is too high, the hardness and strength of the drill bit 10 material will decrease, and the cutting edge will become blunt, thereby reducing the cutting ability of the drill bit 10 and slowing down the drilling speed. Therefore, timely replenishment of water is conducive to extending the service life of the drill bit 10.

[0075] Working principle: The vehicle-mounted rotary drilling machine is specifically operated as follows: move the cart 1 to the pre-drilling position so that the clearance hole 11 on the cart 1 is opposite to the pre-drilling position, and then drive the drilling motor 8 to drive the drill rod 9 to rotate the rod 29, and the drill rod 9 drives the drill bit 10 to rotate, and then drive the reduction motor 12 to drive the rotating shaft 4 to rotate, and the No. 1 screw rod 5 drives the lifting plate 7 to move downward, and the drill bit 10 touches the surface of the mine and drills holes on the surface. Since the overall volume of the vehicle-mounted rotary drilling machine is small and the drill rod 9 is short, the center of gravity of the entire pre-drilling unit is low. During the pre-drilling process, it runs stably, can quickly drill the guide hole, and has high efficiency. At the same time, for some harder mineral surface layers, the pre-drilling unit can also drill holes stably, and in the case of encountering some loose strata, even if it is trapped in the soil layer, it can easily get out of trouble, reducing the consumption of manpower, material and financial resources.
