The primary framework comprises a bottom support part, a top support part and an extension part connecting the two. The top support part comprises a support top plate and a flexible connection assembly. The flexible connection assembly comprises a first fixing part, a second fixing part and a flexible part between the two. The drill box is slidably arranged on the primary framework.

Description

Technical Field

[0001] This invention relates to the field of coal mining technology, and in particular to an integrated drilling and anchoring bolt drilling rig. Background Technology

[0002] In mine roadway excavation and support engineering, anchor drilling rigs are key construction equipment, and their performance stability directly affects the project progress and safety. However, some technical challenges exist during the operation of anchor drilling rigs that urgently need to be addressed.

[0003] First, during operation, the roof of the anchor drilling rig comes into contact with the coal face. Due to the irregularity of the coal face and the dynamic changes of the roof, this contact is often impactful. This impact not only damages the roof and coal face but also adversely affects the drilling rig structure, shortens its service life, increases maintenance costs, and may also pose a threat to the safety of operators.

[0004] Secondly, an improperly designed position of the fluid distribution plate on the drill frame of the anchor drilling rig can lead to an inappropriate length of the connecting pipeline between the fluid distribution plate and the drill box. If the pipeline is too long, it will not only increase the system's fluid resistance and reduce work efficiency, but also make it prone to contact, collision, and interference with surrounding structures during various drilling operations. This could result in the pipeline being pulled apart or damaged, interrupting construction and potentially causing hydraulic system leaks, affecting the normal operation of the drilling rig and construction safety. Summary of the Invention

[0005] The present invention aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, embodiments of the present invention propose an integrated drilling and anchoring bolt drilling rig that is safe, reliable, and efficient.

[0007] The integrated drilling and anchoring bolt drilling rig of this invention includes:

[0008] A primary frame includes a bottom support, a top support, and a telescopic part connecting the two, such that the telescopic part drives the top support to move along the length direction of the primary frame. The top support includes a supporting top plate and multiple flexible connecting components, which are sequentially connected along the length direction of the primary frame. Each flexible connecting component includes a first fixing member, a second fixing member, and a flexible member. The first fixing member and the second fixing member are spaced apart along the length direction of the primary frame, and a buffer zone is defined between the first fixing member and the second fixing member. The flexible member is connected to the first fixing member and the second fixing member and is placed within the buffer zone.

[0009] A drill box is mounted on the primary frame. The drill box is slidable between the bottom support and the top support along the length of the primary frame. The drill box has two extreme positions on the primary frame. The distance between the two extreme positions along the length of the primary frame is s.

[0010] A fluid distribution plate is disposed on the primary frame and connected to the drill box via a pipeline. The distance between the position of the fluid distribution plate on the primary frame and the drill box at any extreme position in the length direction of the primary frame is s / 2.

[0011] The integrated drilling and anchoring bolt drilling rig of this invention incorporates a flexible structure at the connection point between the drilling rig and the supporting top plate. This structure effectively absorbs and disperses impact forces, thereby reducing the impact on the drilling rig and improving its stability and safety. Simultaneously, the position of the fluid distribution plate on the drill frame is optimized to ensure an appropriate length of the connecting pipeline between the fluid distribution plate and the drill box, avoiding problems caused by excessively long pipelines, thus improving pipeline safety and drilling rig efficiency.

[0017] In some embodiments, the secondary cylinder includes a cylinder rod, a primary cylinder barrel, and a secondary cylinder barrel.

One end of the cylinder rod is slidably disposed inside the primary cylinder barrel, and the other end of the cylinder rod is connected to the bottom support portion. The secondary cylinder barrel is fitted onto the primary cylinder barrel.

[0018] In some embodiments, the secondary cylinder is provided with a transmission assembly, which includes bearings at both ends of the secondary cylinder, a chain wrapped around the bearings, and a chain fixing block connecting the chain to the secondary skeleton. The drill box fixing sleeve is connected to the chain, and the chain fixing block and the drill box fixing sleeve divide the chain into two segments.

[0051] 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.

[0052] The following describes an embodiment of the integrated drilling and anchoring bolt drilling rig of the present invention with reference to the accompanying drawings.

[0053] like Figures 1 to 4 As shown, the integrated drilling and anchoring bolt drilling rig of this embodiment includes: a primary frame 1, a drill box 2, and a fluid distribution plate 3.

[0054] The length direction of the anchor drilling rig refers to, for example, Figure 1The vertical direction shown in the diagram refers to the width direction of the anchor drilling rig, as shown in the diagram. Figure 1 The left and right directions shown in the diagram refer to the thickness direction of the anchor drilling rig, as shown in the diagram. Figure 1 The up and down directions are shown in the diagram.

[0055] The primary frame 1 includes a bottom support 11, a top support 12, and a telescopic part 13 for connecting the two, so that the telescopic part 13 drives the top support 12 to move along the length direction of the primary frame 1 during the extension and retraction of the telescopic part 13.

[0056] The top support 12 includes a supporting top plate 121 and multiple flexible connecting components 122, which are connected sequentially along the length of the primary frame 1. Each flexible connecting component 122 includes a first fixing member 1221, a second fixing member 1222, and a flexible member 1223. The first fixing member 1221 and the second fixing member 1222 are arranged at intervals along the length of the primary frame 1, and a buffer zone is defined between the first fixing member 1221 and the second fixing member 1222. The flexible member 1223 is connected to the first fixing member 1221 and the second fixing member 1222 and is placed within the buffer zone.

[0057] It is understandable that, such as Figure 3 and Figure 4 As shown, when the supporting roof 121 comes into contact with the coal wall, the first fixing member 1221 and the second fixing member 1222 move closer to each other as the force increases, and the flexible member 1223 adapts to bending deformation after being squeezed, thereby playing a buffering role.

[0058] Therefore, the integrated drilling and anchoring bolt drilling rig of this embodiment of the invention, by adding a flexible structure to the part of the supporting top plate 121 that connects to the drilling rig, can effectively absorb and disperse the impact force, thereby reducing the impact on the drilling rig and improving the stability and safety of the drilling rig.

[0059] Optionally, such as Figure 3 and Figure 4 As shown, there are multiple flexible components 1223, which are distributed at intervals along the width direction of the primary skeleton 1 to further improve the buffering effect of the flexible connection assembly 122.

[0060] The drill box 2 is mounted on the primary frame 1 and can slide between the bottom support 11 and the top support 12 along the length of the primary frame 1. The liquid distribution plate 3 is mounted on the primary frame 1 and is connected to the drill box 2 via pipeline.

[0061] The drill box 2 has two extreme positions during the sliding process. One extreme position is when the drill box 2 slides to the position of the bottom support 11, and the other extreme position is when the drill box 2 slides to the position of the top support 12.

[0062] like Figures 20 to 23As shown, when the drill box 2 is in two extreme positions, the distance between the drill box 2 pipeline interface and the length direction of the primary skeleton 1 is s.

[0063] The distance between the liquid distribution plate 3 pipeline interface and the drill box 2 pipeline interface at any extreme position in the length direction of the primary skeleton 1 is s / 2.

[0064] Therefore, the integrated drilling and anchoring bolt drilling rig of this invention optimizes the position of the liquid distribution plate 3 on the drilling frame, ensuring that the length of the connecting pipe between the liquid distribution plate 3 and the drilling box 2 is appropriate, avoiding problems caused by excessively long pipes, thereby improving the safety of the pipes and the working efficiency of the drilling rig.

[0065] In some embodiments, such as Figure 2 and Figure 5 As shown, the telescopic part 13 includes a support plate 131, a slide rail fixing sleeve 132, a sliding column 133, and a support cylinder 134. The bottom end of the support plate 131 is connected to the bottom support part 11, and the slide rail fixing sleeve 132 is located at the top end of the support plate 131. The slide rail fixing sleeve 132 has a first sliding hole 1321, and the sliding column 133 slides through the first sliding hole 1321. The end of the sliding column 133 away from the bottom support part 11 is connected to the top support part 12. The cylinder of the support cylinder 134 is connected to the bottom support part 11, and the piston rod of the support cylinder 134 is connected to the top support part 12.

[0066] Understandably, the piston rod of the supporting cylinder 134 extends and retracts to move the top support 12. In actual operation, the piston rod of the supporting cylinder 134 extends, thereby pushing the supporting roof plate 121 gradually closer to and into contact with the coal wall.

[0067] In some embodiments, such as Figure 1 and Figure 6 As shown, the anchor drilling rig also includes a secondary frame 4, which includes a secondary base plate 41, a secondary top plate 42, a first guide post 43, and a second guide post 44. The two ends of the first guide post 43 are connected to the secondary base plate 41 and the secondary top plate 42, respectively, and the two ends of the second guide post 44 are connected to the secondary base plate 41 and the secondary top plate 42, respectively.

[0068] The drill box 2 is mounted on the first guide post 43 and slides axially between the secondary bottom plate 41 and the secondary top plate 42. The slide rail fixing sleeve 132 has a second sliding hole 1322, through which the second guide post 44 slides axially. The secondary frame 4 slides axially between the bottom support 11 and the top support 12.

[0069] Optionally, such as Figure 1 , Figure 7 and Figure 8As shown, the drill box 2 is assembled onto the first guide post 43 via a drill box fixing sleeve 21. The drill box fixing sleeve 21 has an assembly hole 211, through which the first guide post 43 slides.

[0070] Understandably, the primary frame 1, secondary frame 4, and drill box 2 all undergo axial movement to ensure the straightness and stability of the drilling operation, avoid unexpected movement, and thus improve the accuracy of drilling and the installation quality of the anchor bolts.

[0071] In some embodiments, such as Figure 1 as well as Figures 9 to 13 As shown, the anchor drilling rig also includes a secondary hydraulic cylinder 5. The secondary hydraulic cylinder 5 is connected to the secondary frame 4 and the drill box 2. The first stroke of the secondary hydraulic cylinder 5 is used to drive the secondary frame 4 to slide on the primary frame 1, and the second stroke of the secondary hydraulic cylinder 5 is used to drive the drill box 2 to slide on the secondary frame 4.

[0072] Optionally, the secondary cylinder 5 includes a cylinder rod 51, a primary cylinder 52, and a secondary cylinder 53. The two ends of the primary cylinder 52 are connected to the secondary bottom plate 41 and the secondary top plate 42, respectively. One end of the cylinder rod 51 is slidably disposed inside the primary cylinder 52, and the other end of the cylinder rod 51 is connected to the bottom support 11. The secondary cylinder 53 is fitted onto the primary cylinder 52.

[0073] Understandably, the cylinder rod 51 extends to allow the primary cylinder 52 to drive the secondary frame 4 to slide, and the secondary cylinder 53 slides on the primary cylinder 52, thereby driving the drill box 2 to slide. Specifically, the secondary base plate 41 has oil inlet and outlet channels connected to the secondary cylinder 5, which control the forward and backward movement of the secondary cylinder 5 respectively.

[0074] Optionally, the secondary cylinder 53 is provided with a transmission assembly 531, which includes bearings 5311 at both ends of the secondary cylinder 53, a chain 5312 surrounding the bearings 5311, and a chain fixing block 5313 connecting the chain 5312 to the secondary frame 4. The drill box fixing sleeve 21 is connected to the chain 5312.

[0075] Understandably, during the sliding process of the secondary cylinder 53, the chain 5312 is connected to the secondary frame 4 through the chain fixing block 5313, thereby driving the chain 5312 to rotate around the bearing 5311, which in turn drives the drill box 2 to slide on the secondary frame 4 through the drill box fixing sleeve 21. The bearing 5311 is a roller bearing 5311, which is connected to the peripheral wall of the secondary cylinder 53 through the sleeved shaft.

[0076] Furthermore, the chain fixing block 5313 and the drill box fixing sleeve 21 divide the chain 5312 into two sections. The end of either section of the chain 5312 connected to the drill box fixing sleeve 21 is movable, thereby adjusting the tension of the chain 5312.

[0077] Specifically, the drill box fixing sleeve 21 is provided with a fixing part 212 and a moving part 213. The fixing part 212 is connected to one end of the chain 5312, and the moving part 213 is connected to the other end of the chain 5312. A bolt 214 is connected between the moving part 213 and the fixing part 212, so that the moving part 213 can move on the drill box fixing sleeve 21 by means of threaded transmission. The tension of the chain 5312 can be adjusted by adjusting the distance between the moving part 213 and the fixing part 212.

[0078] In some embodiments, such as Figure 1 as well as Figures 12 to 15 As shown, the anchor drilling rig also includes a clamp assembly 6, which includes a clamp 61, a clamp cylinder 62, and a clamp hose 63.

[0079] The clamp 61 is connected to the clamp cylinder 62, which is mounted on the secondary top plate 42. The clamp oil pipe 63 includes an inner pipe 631 and an outer pipe 632 that can slide relative to each other. A first oil supply channel is provided on the bottom support 11, and the end of the inner pipe 631 is connected to the bottom support 11 and communicates with the first oil supply channel. A second oil supply channel is provided on the secondary top plate 42 and communicates with the oil chamber of the clamp cylinder 62. The end of the outer pipe 632 is connected to the secondary top plate 42 and communicates with the second oil supply channel.

[0080] It is understandable that the clamp cylinder 62 is supplied with oil through the first oil supply channel, the clamp oil pipe 63 and the second oil supply channel connected in sequence, thereby controlling the forward and backward movement of the clamp cylinder 62 and thus controlling the opening and closing of the clamp 61.

[0081] Furthermore, after the primary frame 1 is deployed, as the secondary frame 4 slides on the primary frame 1, the secondary frame 4 drives the clamp cylinder 62 and the clamp 61 to move, and at the same time drives the clamp oil pipe 63 to extend and retract, thereby achieving normal oil supply to the clamp cylinder 62 through the extendable clamp oil pipe 63.

[0082] Therefore, the clamp tubing 63 is built into the drill frame and adopts a telescopic sleeve structure, moving synchronously with the secondary frame 4, thereby avoiding the problem of the oil supply hose of the external clamp cylinder 62 being easily snagged and improving the stability of the clamp 61 clamping operation.

[0083] In some embodiments, such as Figure 1 and Figure 16 As shown, a protective plate 31 is provided at the pipe interface of the liquid distribution plate 3.

[0084] Understandably, the pipe interface is a point in the hydraulic system prone to leakage. The protective plate 31 effectively protects the pipe interface, preventing damage to the pipes due to external forces such as collisions and compression during drilling operations, thereby reducing operational risks and ensuring the safety of operators.

[0085] In some embodiments, such as Figures 17 to 19 As shown, the secondary frame 4 is provided with a flexible clamping assembly 45 for clamping the pipeline between the liquid distribution plate 3 and the drill box 2. The flexible clamping assembly 45 includes a support frame 451, a stabilizing member 452 and a clamping member 453 connected in sequence.

[0086] The support frame 451 is connected to the secondary frame 4, and the clamping member 453 is clamped on the pipeline between the liquid distribution plate 3 and the drill box 2. The stabilizing member 452 includes a first flexible part 4521, a second flexible part 4522, and a third flexible part 4523 connected together. 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.

[0087] It should be noted that during drilling operations, the drilling rig may be in a horizontal, inclined, or vertical state depending on the drilling orientation. Especially in the horizontal and inclined states, in order to prevent the hydraulic lines of the drill box 2 from sagging under the action of gravity, the anchor drilling rig of this embodiment of the invention is equipped with a flexible clamping component 45 on the lines.

[0088] The first flexible part 4521, the second flexible part 4522, and the third flexible part 4523 are arranged between the support frame 451 and the clamping member 453, allowing the clamping member 453 to deflect to a certain extent in the first, second, and third directions, respectively, thereby supporting the pipeline while ensuring its flexibility. The first, second, and third directions are respectively as follows: Figure 19 The X-axis, Y-axis, and Z-axis directions are shown in the diagram.

[0089] Optionally, the support frame 451 is fitted onto the second guide post 44 of the secondary frame 4, allowing for a certain axial movement. The fitted portion is also equipped with a limiting protrusion to restrict the rotation of the support frame 451 around the second guide post 44 by means of locking. Furthermore, a curved structure is added to the middle of the support frame 451 to avoid interfering with the sliding of the drill box fixing sleeve 21.

[0090] In some embodiments, the distance d between the pipe interface of the fluid distribution plate 3 and the pipe interface of the drill box 2 at any extreme position in the thickness direction of the primary frame 1 is defined as d, the minimum bending radius of the hydraulic pipe of the drill box 2 is defined as r, and the length l of a given hydraulic pipe is determined according to the relationship between r and d. o .

[0091] Optionally, such as Figure 20 As shown, when r < d / 2, the following relation is satisfied:

[0092]

[0093] Optionally, such as Figure 21 As shown, when r = d / 2, the following relation is satisfied:

[0094]

[0095] Optionally, such as Figure 22 As shown, when d / 2 < r ≤ d, the following relation is satisfied:

[0096]

[0097] Optionally, such as Figure 23 As shown, when r > d, the following relation is satisfied:

[0098]

[0099] Therefore, the final length l of the pipeline is l o The sum of ε and ε, where ε is a correction factor. This invention proposes a design method for minimum pipeline length based on the minimum bending radius of the hydraulic pipeline and the relative position of the fluid distribution plate 3 and the drilling box 2. While ensuring the reliability of the hydraulic pipeline, it reduces the redundant length of the pipeline, effectively solves the problem of pipe tangling, effectively reduces the pressure loss and energy consumption of the hydraulic system, improves the working efficiency of the hydraulic system, and extends the service life of the pipeline.
