Description

Technical Field

[0001] The present invention relates to the manufacturing and application fields of coal mine roadway support equipment and blast hole construction equipment, and particularly relates to a rock drill shank adapter mechanism, a rock drill, and an integrated rock roadway drilling and bolting machine. Background Art

[0002] In China, mechanization, automation, and intelligence have been achieved in fully mechanized coal mining faces. However, full mechanization has not been completely realized in driving faces, especially in terms of blast hole construction and bolt and cable support in rock roadway driving faces. Most of them still need to be realized by traditional hand-held drills. This will affect the quality of bolt support and blast hole construction, such as the accuracy of drilling azimuth, depth, and diameter, as well as the installation quality of bolts and the quality of blast driving. Moreover, it also involves the personal safety, labor intensity, working conditions, and support efficiency of operators.

[0003] At present, in addition to the manual construction process, there are two driving processes for rock roadways. One is to use a TBM full-face tunnel boring machine, which integrates two or more on-board rock drills to complete the functions of hard rock driving and bolt and cable support with one device. However, this device has disadvantages such as high price, large volume, heavy weight, and long installation time, and is not suitable for short-distance roadway driving, with low cost performance. The other is to use an alternating operation form of two devices, that is, a rock drill jumbo for blast hole construction and a bolt drill jumbo for bolt and cable support. This process has scattered procedures and requires frequent equipment switching, resulting in long operation time and low efficiency. In addition, affected by other equipment on the working face, it is more difficult for multiple devices to coordinate operations in a narrow roadway, occupying a large space, and there are problems such as difficulties in equipment entry and exit and passing each other, further slowing down the construction progress.

[0004] In view of the above situation, it is necessary to develop an integrated rock roadway drilling and bolting machine that combines multiple functions such as blast hole construction and bolt support, so that it is applicable to various driving processes, expands the application range of products, meets the industry requirements, gives play to the advantages of mechanized operations, solves the problems existing in the driving and support of existing rock roadway driving faces, and realizes a comprehensive improvement in terms of safety, efficiency, and quality standardization.

One end of the drill arm slewing group is rotatably connected with the working platform, and the other end is movably connected with the outer sleeve of the drill arm telescopic group and the fixed end of the telescopic oil cylinder of the drill arm support group through a slewing seat respectively. The slewing oil cylinder of the drill arm slewing group drives the slewing seat to rotate horizontally relative to the working platform. The movable end of the telescopic oil cylinder of the drill arm support group is movably connected with the bottom of the outer sleeve of the drill arm telescopic group and is used for driving the drill arm telescopic group to adjust up and down. The drill arm leveling group is arranged at the top of the inner sleeve of the drill arm telescopic group and extends back and forth with the telescopic oil cylinder of the drill arm telescopic group.

[0026] Adopting the above technical solutions, the present invention has at least the following advantages:

[0027] 1.

When performing blast hole drilling operations, the rock drill has the functions of rotation and impact. When performing bolt support operations, the rock drill only generates a rotational effect and does not exert an impact effect. Moreover, the rotation direction of the rock drill during blast hole drilling is opposite to that during bolt support operations, without mutual interference, greatly improving the construction efficiency.

[0028] 2. The rock roadway drill-anchor jumbo of the present invention integrates a multi-functional drill boom, a replaceable shank adapter sleeve, reduces manual intervention, is applicable to various tunneling processes, expands the application scope of the product, meets the industry requirements, improves the tunneling efficiency, and belongs to a safe, efficient, low-cost and sustainable construction equipment, having remarkable effects in aspects such as reducing the number of workers, improving efficiency and reducing labor intensity.

[0029] 3. Also, through the setting of the aerosol lubrication mechanism, it not only lubricates the rotating shank part of the rock drill, but also can play the roles of heat dissipation, dust prevention, preventing rock debris from entering the rock drill and sealing the rock drill, provides conditions for the sustainable and efficient operation of the rock drill, and prolongs the service life of the rock drill.

[0030] 4. Also, through the setting of the double drill rod holders and the clamping mechanism in the drilling mechanism, the shaking amount in the working state is reduced, the efficiency is improved, the incidence of drill rod breakage is reduced, and the high accuracy and stability are maintained during the drilling process.

[0031] 5. Also, through the side wall attaching plate added to the boom body slewing group in the drill boom mechanism and the two telescopic oil cylinders, it is convenient to realize the side wall attaching operation, and the fitting degree between the drilling mechanism and the working face is significantly improved.

[0032] 6. Also, by installing the drill boom operation platform mechanism on the working platform, which does not move with the drill boom mechanism, it is convenient and stable, and further ensures the safety of the operator. Also, through the electrical system with explosion-proof function, the safety of the operator during the operation of the drill jumbo is further ensured. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention can be more thoroughly understood and the scope of the present invention can be fully conveyed to those skilled in the art.

[0065] In the present invention, unless otherwise stated, the orientation terms such as "upper, lower, top, bottom" are generally in reference to the directions indicated by the accompanying drawings, or in reference to the vertical, perpendicular or gravitational directions of the components themselves; similarly, for the sake of understanding and description, "inner, outer" refer to the inner and outer of the contours of the respective components themselves, but the above orientation terms do not limit the present invention.

[0066] In order to integrate processes, reduce manual intervention, optimize resource utilization, ensure the safety of operators, improve work efficiency and reduce labor intensity, the present embodiment provides a rock roadway drilling and anchoring machine.

[0067] Refer to the attached Figure 1 As shown, the rock roadway drilling and anchoring machine of the present embodiment includes a drilling mechanism 1, a front support mechanism 2, a drill arm mechanism 3, a waterway system 4, a drill arm operation table mechanism 5, a support seat group 6, a hydraulic system 7, a driver's seat operation table mechanism 8, an electrical system 9, a fuel tank section 10, a rear support mechanism 11, a traveling section 12, a cover plate section 13, a motor oil pump section 14, a main body section 15, a four-link mechanism 16, a swing rod mechanism 17 and a work platform 18.

[0068] The support seat group 6, fuel tank part 10, rear support mechanism 11, traveling part 12, cover plate part 13, motor oil pump part 14, four-bar linkage mechanism 16, swing rod mechanism 17, and working platform 18 are all connected to the main body part 15. Among them, the traveling part 12 is connected to the lower part of the main body part 15 and is used to drive the drilling and anchoring machine to move forward and backward. The four-bar linkage mechanism 16 and the swing rod mechanism 17 are connected to the upper front middle part of the main body part 15 and jointly act on the lifting of the working platform 18. The working platform 18 is also connected to the upper front middle part of the main body part 15 through a cylinder pin shaft, and the working platform 18 can be lifted by 1000 mm under the action of the cylinder. The front support mechanism 2, drilling arm mechanism 3, and drilling arm operation platform mechanism 5 are all connected to the working platform 18. The drilling arm mechanism 3 includes two, symmetrically arranged on both sides of the front support mechanism 2. The drilling arm operation platform mechanism 5 is installed on the working platform 18 and does not move with the drilling arm mechanism 3, which is convenient and stable, further ensuring the safety of the operator. The drilling mechanism 1 is arranged at the free end of the drilling arm mechanism 3 and can swing at any angle within the front hemisphere range of the drilling and anchoring machine. The support seat group 6 is connected to the upper middle part of the main body part 15, and the fuel tank part 10, cover plate part 13, motor oil pump part 14, and rear support mechanism 11 are connected to the rear part of the main body part 15.

[0069] Specifically, referring to Figure 2 As shown, the drilling mechanism 1 mainly includes: a rock drill 1-1, a carriage group 1-2, a frame group 1-3, and a sliding base 1-4. The rock drill 1-1 is movably arranged on the upper part of the carriage group 1-2 and realizes the sliding of the rock drill 1-1 on the carriage group 1-2 through a first-stage cylinder and a chain assembly. The carriage group 1-2 is movably arranged on the upper part of the frame group 1-3 and drives the carriage group 1-2 to slide on the frame group 1-3 through a second-stage cylinder, so that the drilling mechanism completes the second-stage propulsion. The bottom of the sliding base 1-4 is used for movably connecting with the drilling arm mechanism 3. A connecting seat 1-5 is arranged on the side of the frame group 1-3, and the lower part of the connecting seat 1-5 is slidably connected with the side of the sliding base 1-4. The frame group 1-3 slides along the sliding base 1-4 under the action of a sliding cylinder 1-6 to increase the stroke of the propulsion mechanism and facilitate the drilling of blast holes. The rock drill 1-1 also includes a clamping mechanism 1-7 and a drill rod holder group 1-8. The lower part of the clamping mechanism 1-7 is fixedly connected to the end of the frame group 1-3 through a telescopic cylinder, and the drill rod holder group 1-8 is fixedly connected to the end of the carriage group 1-2.

[0070] Among them, a wear-resistant plate is also arranged at the bottom of the rock drill 1-1 and is used for directly contacting the upper part of the carriage group 1-2 to ensure the smoothness and wear resistance during the propulsion process of the rock drill. The drill rod holder group 1-8 adopts a double drill rod holder. The double drill rod holder and the clamping mechanism act together, so that the rock drill maintains a high degree of accuracy and stability during the working process, the shaking amount is reduced, and the efficiency is high.

[0071] The improvement of this embodiment also lies in improving the shank adapter mechanism of the rock drill 1-1, so that through the conversion of the adapter sleeve, the operation of drilling blast holes and the operation of driving rock bolts can be realized by using the forward and reverse rotation of the rock drill. Specifically, this embodiment includes two types of shank adapter mechanisms, among which Figures 3 to 8 Figure 1 shows a shank adapter mechanism, which includes a first shank 1-1-1 and a corresponding first adapter sleeve 1-1-2 and a first sealing sleeve 1-1-3 connected thereto. Figures 9 to 11 Figure 2 shows another shank adapter mechanism, which includes a second shank 1-1-1' and a corresponding second adapter sleeve 1-1-2' connected thereto.

[0072] Referring to Figure 3 Figure 3, a spline 1-1-1-1 for connecting with the rock drill 1-1 is provided at the first end of the first shank 1-1-1. From the port to the middle section at the second end of the first shank 1-1-1, there are successively provided an internally left-handed threaded through-hole section 1-1-1-2, an internally hexagonal through-hole section I 1-1-1-3, and an internal water-way through-hole section I 1-1-1-4. A radial water hole 1-1-1-5 communicating with the internal water-way through-hole section I 1-1-1-4 is provided in the middle of the first shank 1-1-1, and the internally left-handed threaded through-hole section 1-1-1-2, the internally hexagonal through-hole section I 1-1-1-3, and the internal water-way through-hole section I 1-1-1-4 are coaxial and the through-hole diameters decrease successively.

[0073] Referring to Figure 4 Figure 4, the first end of the first adapter sleeve 1-1-2 is provided with an externally threaded sealing section I 1-1-2-1 matching the internally left-handed threaded through-hole section 1-1-1-2 of the first shank 1-1-1. The second end of the first adapter sleeve 1-1-2 is provided with a left-handed threaded connection hole I 1-1-2-2 for connecting with the drill rod. A water-through hole I 1-1-2-3 communicating with the internal water-way of the first shank 1-1-1 is provided at the central axis of the first adapter sleeve 1-1-2. Then, as shown in Figure 6As shown, when the first adapter sleeve 1-1-2 is connected to the first drill shank 1-1-1, the drill rod is connected to the left-handed threaded connection hole I 1-1-2-2 of the first adapter sleeve 1-1-2, and the operation of drilling blast holes is realized under the impact and left-handed rotation of the rock drill. The function of the first adapter sleeve 1-1-2 is to extend the drill shank. When the drill rod is directly connected to the inner left-handed threaded through-hole section 1-1-1-2 of the first drill shank 1-1-1, the end of the drill rod may damage the inner hexagonal through-hole section I 1-1-1-3 of the first drill shank 1-1-1 under the left-handed rotation and impact of the rock drill, resulting in damage to the inner hexagonal through-hole section I 1-1-1-3 and inability to connect with the anchor rod. Moreover, the area of the step end face B formed by the left-handed threaded connection hole I 1-1-2-2 and the water passage hole I 1-1-2-3 in the first adapter sleeve 1-1-2 is larger than the area of the step end face A formed by the inner left-handed threaded through-hole section 1-1-1-2 and the inner hexagonal through-hole section I 1-1-1-3 in the first drill shank 1-1-1, which is more conducive to meeting the impact pressure received by the drill rod, as shown in the appendix Figure 6 As shown. That is, the first adapter sleeve 1-1-2 can convert the impact received by the A surface into the impact received by the B surface, increasing the force-receiving area, reducing the pressure received, and being more durable and reliable. Also, the thread direction of the threaded through-hole section in the first drill shank 1-1-1 and the threaded connection hole of the first adapter sleeve 1-1-2 only needs to be the same as the thread direction of the drill rod to meet the connection of the drill rod, and the rotation direction of the rock drill only needs to satisfy driving the drill rod to rotate.

[0074] Referring to the appendix Figure 5 As shown, the first end of the first sealing sleeve 1-1-3 is provided with an external thread sealing section II 1-1-3-1 that matches the inner left-handed threaded through-hole section 1-1-1-2 of the first drill shank 1-1-1. A circular hole 1-1-3-2 for the hexagonal anchor rod to pass through is provided at the central axis of the first sealing sleeve 1-1-3, and a sealing groove I 1-1-3-3 for installing a sealing ring is provided on the inner wall of the circular hole 1-1-3-2. Then, as shown in the appendix Figure 7 As shown, when the first sealing sleeve 1-1-3 is connected to the first drill shank 1-1-1, the hexagonal anchor rod is inserted from the first sealing sleeve 1-1-3, can be clamped with the inner hexagonal through-hole section I 1-1-1-3 of the first drill shank 1-1-1, and the operation of driving the anchor rod is realized under the right-handed rotation of the rock drill. At this time, only the rotation effect is generated, and no impact effect is generated. The main function of the first sealing sleeve 1-1-3 is to set the sealing groove I 1-1-3-3 to overcome the disadvantage that the inner hexagonal through-hole section I 1-1-1-3 is located deep in the first drill shank 1-1-1 and is not conducive to processing the sealing groove. The first sealing sleeve 1-1-3 is not only convenient to process but also extends the connection length of the anchor rod, ultimately improving the stability and accuracy of the drill rod operation.

[0075] Moreover, the outer surface of the first adapter sleeve 1-1-2 is also provided with a resisting end face I 1-1-2-4 that abuts against the end of the first drill shank 1-1-1, and a clamping working face I 1-1-2-5 that matches the installation tool, such as an external square working face. The outer surface of the first sealing sleeve 1-1-3 is also provided with a resisting end face II 1-1-3-4 that abuts against the end of the first drill shank 1-1-1, and a clamping working face II 1-1-3-5 that matches the installation tool, such as an external hexagonal working face.

[0076] That is, for this drill shank adapter mechanism, when the rock roadway drill-anchor jumbo needs to drill blast holes, the first adapter sleeve 1-1-2 is screwed to the first drill shank 1-1-1 to form a good sealing effect, and then it is installed on the rock drill 1-1 through the spline of the first drill shank 1-1-1, and then the drill rod can be directly screwed to realize the blast hole drilling operation. When the rock roadway drill-anchor jumbo needs to drill anchor bolts, the first sealing sleeve 1-1-3 is screwed to the first drill shank 1-1-1 to form a good sealing effect, and then it is installed on the rock drill 1-1 through the spline of the first drill shank 1-1-1, and then the hexagonal drill rod B19 or B22 can be directly inserted to realize the anchor bolt drilling operation.

[0077] Refer to the appendix Figure 8 As shown, the difference between the second drill shank 1-1-1' and the first drill shank 1-1-1 is that the second end of the second drill shank 1-1-1' is successively provided with an internal hexagonal through-hole section II 1-1-1-3' and an internal water passage through-hole section II 1-1-1-4' from the port to the middle section. And a sealing groove II 1-1-3-3' for installing a sealing ring is provided on the side of the internal hexagonal through-hole section II 1-1-1-3' close to the second end of the second drill shank 1-1-1'. The hexagonal anchor bolt is inserted from the second end of the second drill shank 1-1-1' and can be clamped with the internal hexagonal through-hole section II 1-1-1-3', and the anchor bolt drilling operation is realized under the right-handed rotation of the rock drill 1-1. That is, the second drill shank of this drill shank adapter mechanism can directly connect the anchor bolt and realize the sealing of the anchor bolt to complete the anchor bolt drilling operation of the rock drill.

[0078] The outer peripheral surface of the second end of the second drill shank 1-1-1' is also provided with an external left-handed thread connection section 1-1-1-2'. Refer to the appendix Figure 9 As shown, the first end of the second adapter sleeve 1-1-2' is provided with an internal thread sealing section 1-1-2-1' that matches the external left-handed thread connection section 1-1-1-2' of the second drill shank 1-1-1', the second end of the second adapter sleeve 1-1-2' is provided with a left-handed thread connection hole II 1-1-2-2' for connecting the drill rod, and a water passage hole II 1-1-2-3' communicating with the internal water passage of the second drill shank 1-1-1' is provided at the central axis of the second adapter sleeve 1-1-2'. Then as shown in the appendix Figure 10As shown in the figure, when the second adapter sleeve 1-1-2' is connected to the second drill shank 1-1-1', the drill rod is connected to the left-handed threaded connection hole II 1-1-2-2' of the second adapter sleeve 1-1-2', and the operation of drilling blast holes is realized under the impact and left-handed rotation of the rock drill. The function of the second adapter sleeve 1-1-2' is to enable the connection of the drill rod and realize the operation of drilling blast holes by the rock drill.

[0079] That is, the second drill shank adapter mechanism. When the rock roadway drill-anchor jumbo needs to drill blast holes, the second adapter sleeve 1-1-2' is screwed to the first drill shank 1-1-1' to form a good sealing effect, and then it is installed on the rock drill 1-1 through the spline of the first drill shank 1-1-1'. Then the drill rod can be directly installed to realize the operation of drilling blast holes. When the rock roadway drill-anchor jumbo needs to drill anchor bolts, only the second adapter sleeve 1-1-2' needs to be removed, and then the hexagonal drill rod B19 or B22 can be directly installed to realize the operation of drilling anchor bolts.

[0080] Both of the two drill shank adapter mechanisms in this embodiment can make the locking torque of the drilling mechanism large. During construction, the anchor bolts do not need to be tightened twice, and the loss of anchor rate is extremely low.

Then the support roof group 2-1 can be retracted when the drill jumbo is moving to maintain the stability of the drill jumbo, and can be expanded into an arch during the operation of the drill jumbo for temporary support of the open roof. The front support mechanism 2 also has the function of lifting heavy objects (such as: roof nets, W-shaped steel belts, I-beams, etc.), which greatly reduces the labor intensity of workers.
