Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coal mining, and particularly relates to a drill-anchor integrated roof bolting jumbo. BACKGROUND

[0002] In modernized coal mine roadway tunneling and supporting work, the drill-anchor integrated roof bolting jumbo is widely used due to its high efficiency and flexibility. However, in the actual construction process, the hydraulic pipeline connecting the drill box and the liquid distribution plate of the drill machine faces a series of technical challenges.

[0003] Specifically, the drill machine on the roof bolting jumbo may be in a horizontal state, an inclined state or a vertical state according to the different punching positions during operation. In these states, especially in the horizontal state and the inclined state, the hydraulic pipeline is prone to sagging under the action of gravity, which not only affects the flow efficiency of the liquid in the pipeline, but also may cause damage to the pipeline due to the excessive length or bending of the pipeline, and even cause leakage of the hydraulic system, affecting the normal work of the jumbo and the construction safety.

However, the rigid support has certain limitations, it cannot well adapt to the changes of the drill machine in different states, and may cause additional stress to the pipeline, leading to damage to the pipeline or reducing the reliability of the system.

[0052] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0053] The following describes an embodiment of the integrated drilling and anchoring bolt drilling rig of the present invention with reference to the accompanying drawings.

[0054] like Figures 1 to 7 As shown, the integrated drilling and anchoring bolt drilling rig of this embodiment includes: an anchor drilling machine 10, a vehicle body 7, and a drive device 8.

[0055] The anchor drilling rig 10 includes a primary frame 1, a secondary frame 4, and a drill box 2. The primary frame 1 is telescopic, the secondary frame 4 is slidably mounted on the primary frame 1, and the drill box 2 is slidably mounted on the secondary frame 4. The primary frame 1 is provided with a liquid distribution plate 3, which is connected to the drill box 2 via a pipeline.

[0056] The secondary frame 4 is equipped with a flexible clamping device 45 for holding the pipeline between the fluid distribution plate 3 and the drill box 2. The flexible clamping device 45 includes a support frame 451, a flexible component 452, and a clamping component 453 connected in sequence. The support frame 451 is connected to the secondary frame 4, and the clamping component 453 is clamped on the hydraulic pipeline between the fluid distribution plate 3 and the drill box 2. The flexible component 452 includes a first flexible part 4521, a second flexible part 4522, and a third flexible part 4523 connected in sequence. The first flexible part 4521 is bendable and deformable along a first direction, the second flexible part 4522 is bendable and deformable along a second direction, and the third flexible part 4523 is bendable and deformable along a third direction. The first direction, the second direction, and the third direction are all orthogonal to each other.

[0057] The flexible clamping device 45 is arranged between the support frame 451 and the clamping piece 453 through the first flexible part 4521, the second flexible part 4522 and the third flexible part 4523, so that the clamping piece 453 can be deflected in a certain direction in the first direction, the second direction and the third direction respectively, thereby guaranteeing the flexibility of the pipeline while supporting the pipeline. The first direction, the second direction and the third direction are the X-axis direction, the Y-axis direction and the Z-axis direction respectively as shown in the accompanying drawings. Figure 7

[0058] Optionally, the support frame 451 is sleeved on the guide column of the secondary framework 4 and can move axially, and the sleeved part is provided with a limiting protrusion, so that the rotation of the support frame 451 is limited by clamping.

[0059] The vehicle body 7 comprises a track assembly 71, and an operation unit 72 and a hydraulic pump station 73 arranged on the track assembly 71, and the vehicle body 7 is connected with the anchor rod drilling rig 10 through a driving device 8, and the driving device 8 is used for driving the anchor rod drilling rig 10 to move.

[0060] Therefore, the drilling and anchoring integrated anchor rod drilling vehicle of the embodiment of the present application is provided with the flexible clamping device 45 on the hydraulic pipeline connected between the drilling box 2 and the liquid distribution plate 3, appropriate flexible support is provided according to different working states of the drilling rig, the drooping of the pipeline under the action of gravity is avoided, and the pipeline vibration and stress caused by the movement of the drilling rig are reduced.

[0061] In some embodiments, different types of drilling vehicles are selected according to actual construction types, and the driving device 8 connected with the anchor rod drilling rig 10 is different.

[0062] For example, as shown in the accompanying drawings, Figure 1 for the help part anchor rod construction behind the integrated drilling and anchoring machine and the shuttle vehicle, a column type anchor rod drilling vehicle is selected. The drilling vehicle adopts a support structure that can stand on the ground, so as to guarantee the stability of the drilling vehicle when drilling in any position.

[0063] The driving device 8 of the drilling vehicle comprises a support unit 81, a lifting unit 82 and a rotating unit 83, the support unit 81 is arranged on the vehicle body 7 in the vertical direction, the lifting unit 82 is sleeved on the support unit 81 in a slidable manner, and the lifting unit 82 can be deflected around the support unit 81, the rotating unit 83 is connected with the lifting unit 82, the rotating unit 83 can rotate, and the anchor rod drilling rig 10 is arranged on the rotating unit 83. The anchor rod drilling rig 10 can be adjusted horizontally by ±180° and vertically by ±90°, so as to meet the drilling requirements of different heights and different angles.

[0064] For example, as shown in the accompanying drawings, Figure 2 ​As shown, for the supplementary driving operation of the roof anchor rod behind, a cantilever anchor rod drill carriage is selected, and through two groups of swing oil cylinders, the drilling construction demand at any position of the roadway can be completed.

[0065] The driving device 8 of this type of drill carriage includes a cantilever assembly 84 and a turnover seat 85, and the vehicle body 7 is connected with the anchor rod drill 10 through the cantilever assembly 84 and the turnover seat 85 in turn. Moreover, this type of drill carriage is provided with hydraulic legs 74 at the front and rear, which guarantee the stability of the drill carriage when drilling at any position.

[0066] In some embodiments, as shown in Figure 3 , Figure 4 and Figure 10 , the primary framework 1 includes a primary bottom plate 11, a primary top plate 12, and a telescopic part 13 connecting the two, and the telescopic part 13 includes a support plate 131, a slide rail fixing sleeve 132, a sliding column 133, and a support oil cylinder 134.

[0067] It should be noted that the length direction of the anchor rod drill 10 refers to the up-down direction as shown in Figure 3 , the width direction of the anchor rod drill 10 refers to the left-right direction as shown in Figure 3 , and the thickness direction of the anchor rod drill 10 refers to the up-down direction as shown in Figure 3 .

[0068] The bottom end of the support plate 131 is connected with the primary bottom plate 11, the slide rail fixing sleeve 132 is arranged at the top end of the support plate 131, the slide rail fixing sleeve 132 has a first slide hole 1321, the sliding column 133 slides through the first slide hole 1321, the end of the sliding column 133 away from the primary bottom plate 11 is connected with the primary top plate 12, the cylinder barrel of the support oil cylinder 134 is connected with the primary bottom plate 11, and the piston rod of the support oil cylinder 134 is connected with the primary top plate 12.

[0069] It can be understood that the piston rod of the support oil cylinder 134 is extended or retracted to drive the primary top plate 12 to move. In the actual working process, the piston rod of the support oil cylinder 134 is extended, thereby pushing the primary top plate 12 to gradually approach the coal wall and contact the coal wall.

[0070] Optionally, as shown in Figure 3 and Figure 4 and Figures 7 to 9As shown, the primary roof 12 comprises a support roof 121 and a plurality of flexible connecting devices 122 connected in sequence in the length direction of the primary framework 1. The flexible connecting device 122 comprises a first fixing member 1221, a second fixing member 1222 and a flexible connecting member 1223. The first fixing member 1221 and the second fixing member 1222 are arranged in the length direction of the primary framework 1 and are spaced apart, and a buffer zone is defined between the first fixing member 1221 and the second fixing member 1222. The flexible connecting member 1223 is connected to the first fixing member 1221 and the second fixing member 1222 and is arranged in the buffer zone.

[0071] It can be understood that when the support roof 121 is in contact with the coal wall, the first fixing member 1221 and the second fixing member 1222 are close to each other as the force increases, and the flexible connecting member 1223 is adaptively bent and deformed after being extruded, thereby playing a buffering role.

[0072] Therefore, by additionally providing a flexible structure at the part of the support roof 121 connected to the drilling machine, the structure can effectively absorb and disperse the impact force, thereby reducing the impact on the drilling machine and improving the stability and safety of the drilling machine.

[0073] In addition, the flexible connecting member 1223 is a plurality of flexible connecting members 1223 distributed in the width direction of the primary framework 1, further improving the buffering effect of the flexible connecting device 122.

[0074] In some embodiments, the drilling box 2 has two limit positions during sliding, one of which is as shown in Figure 17 when the drilling box 2 slides to the position of the primary bottom plate 11. The other limit position is as shown in Figure 18 when the drilling box 2 slides to the position of the primary top plate 12.

[0075] When the drilling box 2 is in the two limit positions, the distance between the drilling box 2 pipeline interfaces in the length direction of the primary framework 1 is s, and the distance between the liquid distribution plate 3 pipeline interface and the drilling box 2 pipeline interface in the length direction of the primary framework 1 is s / 2.

[0076] Therefore, by optimizing the position of the liquid distribution plate 3 on the drilling machine, the length of the pipeline connecting the liquid distribution plate 3 and the drilling box 2 is moderate, avoiding problems caused by excessively long pipelines, thereby improving the safety of the pipeline and the working efficiency of the drilling machine.

[0077] In some embodiments, as shown in Figure 3 , Figure 10 and Figure 11As shown, the secondary skeleton 4 comprises a secondary bottom plate 41, a secondary top plate 42, a first guide column 43 and a second guide column 44. The two ends of the first guide column 43 are connected with the secondary bottom plate 41 and the secondary top plate 42 respectively, and the two ends of the second guide column 44 are connected with the secondary bottom plate 41 and the secondary top plate 42 respectively.

[0078] The drill box 2 is arranged on the first guide column 43, and the drill box 2 axially slides between the secondary bottom plate 41 and the secondary top plate 42. The slide rail fixing sleeve 132 has a second slide hole 1322, the second guide column 44 slides through the second slide hole 1322, and the secondary skeleton 4 axially slides between the primary bottom plate 11 and the primary top plate 12.

[0079] Optionally, as shown in Figure 12 and Figure 13 , the drill box 2 is provided with a drill box fixing sleeve 21, the drill box fixing sleeve 21 is connected with the drill box 2, the drill box fixing sleeve 21 has an assembly hole 211, and the first guide column 43 slides through the assembly hole 211.

[0080] It can be understood that the primary skeleton 1, the secondary skeleton 4 and the drill box 2 all axially move, which ensures the linearity and stability of the drilling action, avoids unintended movement, and thus improves the accuracy of drilling and the installation quality of the anchor rod.

[0081] In some embodiments, as shown in Figure 3 and Figures 14 to 18 , the anchor rod drilling machine 10 further comprises a secondary oil cylinder 5. The secondary oil cylinder 5 is connected with the secondary skeleton 4 and the drill box 2, a primary stroke of the secondary oil cylinder 5 is used to drive the secondary skeleton 4 to slide on the primary skeleton 1, and a secondary stroke of the secondary oil cylinder 5 is used to drive the drill box 2 to slide on the secondary skeleton 4.

[0082] Optionally, the secondary oil cylinder 5 comprises an oil cylinder rod 51, a primary cylinder barrel 52 and a secondary cylinder barrel 53. The two ends of the primary cylinder barrel 52 are connected with the secondary bottom plate 41 and the secondary top plate 42 respectively, one end of the oil cylinder rod 51 is slidably arranged in the primary cylinder barrel 52, the other end of the oil cylinder rod 51 is connected with the primary bottom plate 11, and the secondary cylinder barrel 53 is sleeved on the primary cylinder barrel 52.

[0083] It can be understood that the oil cylinder rod 51 is extended to drive the primary cylinder barrel 52 to slide with the secondary skeleton 4, and the secondary cylinder barrel 53 slides on the primary cylinder barrel 52 to drive the drill box 2 to slide. Specifically, the secondary bottom plate 41 has an oil inlet and return passage in communication with the secondary oil cylinder 5, which respectively controls the forward and backward movement of the secondary oil cylinder 5.

[0084] In some embodiments, as shown in Figure 3 and Figures 14 to 18 , the anchor rod drilling machine 10 further comprises a secondary oil cylinder 5. The secondary oil cylinder 5 is connected with the secondary skeleton 4 and the drill box 2, a primary stroke of the secondary oil cylinder 5 is used to drive the secondary skeleton 4 to slide on the primary skeleton 1, and a secondary stroke of the secondary oil cylinder 5 is used to drive the drill box 2 to slide on the secondary skeleton 4.As shown, the anchor drill 10 further comprises a transmission assembly 531, which comprises bearings 5311 arranged at both ends of the secondary cylinder 53, a chain 5312 wrapped around the bearings 5311, and a chain fixing block 5313 connecting the chain 5312 with the secondary framework 4. The drill box fixing sleeve 21 is connected with the chain 5312.

[0085] It can be understood that, in the process of sliding of the secondary cylinder 53, the chain 5312 is connected with the secondary framework 4 through the chain fixing block 5313, thereby driving the chain 5312 to rotate around the bearings 5311, and further driving the drill box 22 to slide on the secondary framework 4 through the drill box fixing sleeve 21. The bearings 5311 are selected as roller bearings 5311, which are connected with the peripheral wall of the secondary cylinder 53 through a sleeved shaft.

[0086] Optionally, the chain fixing block 5313 and the drill box fixing sleeve 21 divide the chain 5312 into two sections, and one end of any section of the chain 5312 connected with the drill box fixing sleeve 21 is movable, thereby playing a role of adjusting the tension of the chain 5312.

[0087] Specifically, the drill box fixing sleeve 21 is provided with a fixed part 212 and a movable part 213, the fixed part 212 is connected with one section of the chain 5312, and the movable part 213 is connected with another section of the chain 5312. A bolt 214 is connected between the movable part 213 and the fixed part 212, so that the movable part 213 moves on the drill box fixing sleeve 21 in a threaded transmission manner, thereby adjusting the distance between the movable part 213 and the fixed part 212 to adjust the tension of the chain 5312.

[0088] In some embodiments, as shown in Figure 3 and Figures 17 to 20 As shown, the anchor drill 10 further comprises a clamp assembly 6, which comprises a clamp 61, a clamp oil cylinder 62, and a clamp oil pipe 63.

[0089] The clamp 61 is connected with the clamp oil cylinder 62, and the clamp oil cylinder 62 is arranged on the secondary top plate 42. The clamp oil pipe 63 comprises an inner pipe 631 and an outer pipe 632 which are relatively slidable. The first level bottom plate 11 is provided with a first oil supply passage, and the end of the inner pipe 631 is connected with the first level bottom plate 11 and communicates with the first oil supply passage. The secondary top plate 42 is provided with a second oil supply passage which communicates with the oil cavity of the clamp oil cylinder 62, and the end of the outer pipe 632 is connected with the secondary top plate 42 and communicates with the second oil supply passage.

[0090] It can be understood that, by sequentially connecting the first oil supply passage, the clamp oil pipe 63, and the second oil supply passage, the oil supply to the clamp oil cylinder 62 is realized, and the forward and backward movements of the clamp oil cylinder 62 are respectively controlled, thereby controlling the opening and closing of the clamp 61.

[0091] And, after the first skeleton 1 is unfolded, in the process of the second skeleton 4 sliding on the first skeleton 1, the second skeleton 4 drives the clamp oil cylinder 62 and the clamp 61 to move, and drives the clamp oil pipe 63 to extend and retract, so that the clamp oil cylinder 62 is normally supplied with oil through the telescopic clamp oil pipe 63.

[0092] Therefore, the clamp oil pipe 63 is built in the drilling rig, and the telescopic sleeve structure is adopted to follow the synchronous movement of the second skeleton 4, so that the problem that the external clamp oil cylinder 62 supply oil hose is easily hung off is avoided, and the stability of the clamp 61 clamping operation is improved.

[0093] In some embodiments, as shown in Figure 3 and Figure 21 The liquid distribution plate 3 is provided with a protection plate 31 at the pipeline interface.

[0094] It can be understood that, since the pipeline interface is a part prone to leakage in the hydraulic system. The protection plate 31 can effectively protect the pipeline interface, avoid damage to the pipeline caused by external factors such as collision, extrusion, etc. during the operation of the drilling machine, thereby reducing the operation risk and ensuring the safety of the operator.
