Description

Technical Field

[0002] In the mine tunnel excavation and support project, the anchor drill is a key construction equipment, and its performance stability directly affects the progress and safety of the project. However, in the working process of the anchor drill, there are some technical problems that need to be solved urgently.

[0003] First, when the anchor drilling rig is operating, its supporting roof will contact the coal wall. Due to the irregularity of the coal wall and the dynamic changes of the roof, this contact is often impactful. This impact will not only damage the roof and coal wall, but also have an adverse effect on the drilling rig structure, shorten its service life, increase maintenance costs, and may also pose a threat to the safety of operators.

[0004] Secondly, the location design of the liquid distribution plate of the anchor drilling rig on the drilling frame is unreasonable, which will lead to the inappropriate length of the pipeline connecting the liquid distribution plate and the drill box. If the pipeline is too long, it will not only increase the fluid resistance of the system and reduce work efficiency, but also when the drilling rig performs various actions, the overly long pipeline is prone to contact, collision and interference with the surrounding structure, which may cause the pipeline to be pulled off or damaged, which will not only interrupt the construction, but also cause leakage of the hydraulic system, affecting the normal operation of the drilling rig and construction safety.

[0051] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0052] The following describes a drilling and anchoring integrated anchor drilling rig according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0053] like Figures 1 to 4 As shown, the drilling and anchoring integrated anchor drilling rig of the embodiment of the present invention comprises: a primary frame 1, a drilling box 2 and a liquid distribution plate 3.

[0054] Among them, the length direction of the anchor drilling rig refers to Figure 1The vertical direction shown in the figure, the width direction of the anchor drilling rig refers to Figure 1 The left and right directions shown in the figure, the thickness direction of the anchor drilling rig refers to Figure 1 The up and down directions shown in .

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

[0056] The top support portion 12 includes a supporting top plate 121 and a plurality of flexible connection components 122, and the plurality of flexible connection components 122 are sequentially connected in the length direction of the primary frame 1. The flexible connection components 122 include 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 direction of the primary frame 1, a buffer zone is defined between the first fixing member 1221 and the second fixing member 1222, and the flexible member 1223 is connected to the first fixing member 1221 and the second fixing member 1222 and is placed in the buffer zone.

[0057] It is understandable that if Figure 3 and Figure 4 As shown, when the supporting top plate 121 contacts the coal wall, the first fixing member 1221 and the second fixing member 1222 approach each other as the force increases, and the flexible member 1223 is adaptively bent and deformed after being squeezed, thereby playing a buffering role.

[0058] Therefore, the drilling and anchoring integrated anchor drilling rig of the embodiment of the present invention adds a flexible structure to the part where the supporting top plate 121 connects the drilling rig, and the structure 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] Alternatively, if Figure 3 and Figure 4 As shown, there are multiple flexible members 1223 , and the multiple flexible members 1223 are spaced apart and distributed along the width direction of the primary skeleton 1 , so as to further improve the buffering effect of the flexible connection component 122 .

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

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

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

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

[0064] Therefore, the integrated anchor drilling rig of the embodiment of the present invention optimizes the position of the liquid distribution plate 3 on the drill frame to ensure that the length of the pipeline connecting the liquid distribution plate 3 and the drill box 2 is moderate, avoiding problems caused by excessively long pipelines, thereby improving the safety of the pipelines and the working efficiency of the drilling rig.

[0065] In some embodiments, 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 supporting oil cylinder 134. The bottom end of the support plate 131 is connected to the bottom supporting part 11, and 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 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 supporting part 11 is connected to the top supporting part 12. The cylinder barrel of the supporting oil cylinder 134 is connected to the bottom supporting part 11, and the piston rod of the supporting oil cylinder 134 is connected to the top supporting part 12.

[0066] It is understandable that the piston rod of the supporting oil cylinder 134 is extended and retracted to drive the supporting part 12 to move. In the actual working process, the piston rod of the supporting oil cylinder 134 is extended, thereby pushing the supporting top plate 121 to gradually approach the coal wall and contact the coal wall.

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

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

[0069] Alternatively, if Figure 1 , Figure 7 and Figure 8As shown, the drill box 2 is assembled on the first guide column 43 through the drill box fixing sleeve 21. The drill box fixing sleeve 21 has an assembly hole 211, and the first guide column 43 slides through the assembly hole 211.

[0070] It can be understood that the primary frame 1, the secondary frame 4 and the drill box 2 all move axially to ensure the linearity and stability of the drilling action and avoid unexpected movement, thereby improving the accuracy of drilling and the installation quality of the anchor rod.

[0071] In some embodiments, Figure 1 as well as Figures 9 to 13 As shown, the anchor drilling rig also includes a secondary oil cylinder 5. The secondary oil cylinder 5 is connected to the secondary frame 4 and the drill box 2, and the primary stroke of the secondary oil cylinder 5 is used to drive the secondary frame 4 to slide on the primary frame 1, and the secondary stroke of the secondary oil 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 barrel 52 and a secondary cylinder barrel 53, the two ends of the primary cylinder barrel 52 are respectively connected to the secondary bottom plate 41 and the secondary top plate 42, one end of the cylinder rod 51 is slidably disposed in the primary cylinder barrel 52, the other end of the cylinder rod 51 is connected to the bottom support portion 11, and the secondary cylinder barrel 53 is sleeved on the primary cylinder barrel 52.

[0073] It can be understood that the oil cylinder rod 51 extends so that the primary cylinder 52 drives the secondary frame 4 to slide, and the secondary cylinder 53 slides on the primary cylinder 52 to drive the drill box 2 to slide. Specifically, the secondary bottom plate 41 has an oil inlet and return channel connected to the secondary oil cylinder 5, which controls the forward and backward movement of the secondary oil cylinder 5 respectively.

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

[0075] It is understandable that, during the sliding process of the secondary cylinder 53, since the chain 5312 is connected to the secondary frame 4 through the chain fixing block 5313, the chain 5312 is driven to rotate around the bearing 5311, and then the drill box 2 is driven to slide on the secondary frame 4 through the drill box fixing sleeve 21. The bearing 5311 is a roller bearing 5311, and the bearing 5311 is connected to the peripheral wall of the secondary cylinder 53 through the sleeve shaft.

[0076] Furthermore, 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 to the drill box fixing sleeve 21 is movable, thereby playing a role in adjusting the tension of the chain 5312.

[0077] Specifically, the drill box fixing sleeve 21 is provided with a fixed portion 212 and a movable portion 213, the fixed portion 212 is connected to one section of the chain 5312, and the movable portion 213 is connected to the other section of the chain 5312. A bolt 214 is connected between the movable portion 213 and the fixed portion 212, so that the movable portion 213 can move on the drill box fixing sleeve 21 by thread transmission, so that the distance between the movable portion 213 and the fixed portion 212 can be adjusted to adjust the tension of the chain 5312.

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

[0079] The clamp 61 is connected to the clamp oil cylinder 62, and the clamp oil cylinder 62 is arranged 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. The bottom support part 11 is provided with a first oil supply channel, and the end of the inner pipe 631 is connected to the bottom support part 11 and communicates with the first oil supply channel. The secondary top plate 42 is provided with a second oil supply channel that communicates with the oil cavity of the clamp oil cylinder 62, and 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 can be understood that the oil supply to the clamp cylinder 62 is achieved through the first oil supply channel, the clamp oil pipe 63 and the second oil supply channel which are connected in sequence, and the forward and backward movements of the clamp cylinder 62 are controlled respectively, thereby controlling the opening and closing of the clamp 61.

[0081] Moreover, after the primary skeleton 1 is unfolded, while the secondary skeleton 4 slides on the primary skeleton 1, the secondary skeleton 4 drives the clamp cylinder 62 and the clamp 61 to move, and at the same time drives the clamp oil pipe 63 to retract and retract, thereby realizing normal oil supply to the clamp cylinder 62 through the retractable clamp oil pipe 63.

[0082] Therefore, the clamp oil pipe 63 is built into the drill rig and adopts a telescopic sleeve structure to move synchronously with the secondary skeleton 4, thereby avoiding the problem of the oil supply hose of the external clamp cylinder 62 being easily hung up and improving the stability of the clamping operation of the clamp 61.

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

[0084] It is understandable that since the pipeline interface is a part of the hydraulic system that is prone to leakage, the protective plate 31 can effectively protect the pipeline interface and prevent pipeline damage caused by external forces such as collision and extrusion during the operation of the drilling rig, thereby reducing the operation risk and ensuring the safety of the operator.

[0085] In some embodiments, Figures 17 to 19 As shown, a flexible clamping assembly 45 for clamping the pipeline between the liquid distribution plate 3 and the drilling box 2 is provided on the secondary skeleton 4. The flexible clamping assembly 45 includes a supporting frame 451, a stabilizing member 452 and a clamping member 453 which are 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 drilling box 2. The stabilizing member 452 includes a first flexible portion 4521, a second flexible portion 4522 and a third flexible portion 4523 connected to each other, the first flexible portion 4521 can be bent and deformed along a first direction, the second flexible portion 4522 can be bent and deformed along a second direction, and the third flexible portion 4523 can be bent and deformed along a third direction, and the first direction, the second direction and the third direction are orthogonal to each other.

[0087] It should be noted that when the drilling rig is drilling, depending on the orientation of the drilling, the drilling rig may be in a horizontal state, an inclined state, or a vertical state. Especially in the horizontal state and the inclined state, in order to prevent the hydraulic pipeline of the drill box 2 from sagging under the action of gravity, the anchor drilling rig of the embodiment of the present invention is provided with a flexible clamping assembly 45 on the pipeline.

[0088] The first flexible portion 4521, the second flexible portion 4522 and the third flexible portion 4523 are arranged between the support frame 451 and the clamping member 453, so that the clamping member 453 can be deflected to a certain extent in the first direction, the second direction and the third direction respectively, thereby supporting the pipeline while ensuring the flexibility of the pipeline. The first direction, the second direction and the third direction are respectively as follows: Fig.19 The X-axis direction, Y-axis direction and Z-axis direction shown in .

[0089] Optionally, the support frame 451 is mounted on the second guide column 44 of the secondary frame 4, and can generate a certain axial movement. The mounted part is also provided with a limiting protrusion, which limits the rotation of the support frame 451 around the second guide column 44 by locking. In addition, a curved structure is added in the middle of the support frame 451 to avoid interference with the sliding of the drill box fixing sleeve 21.

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

[0091] Alternatively, if Fig. 20 As shown, when r<d / 2, the relationship is satisfied:

[0092]

[0093] Alternatively, if Fig.21 As shown, when r = d / 2, the relationship is satisfied:

[0094]

[0095] Alternatively, if Fig. 22 As shown, when d / 2<r≤d, the relationship is satisfied:

[0096]

[0097] Alternatively, if Fig.23 As shown, when r>d, the relationship is satisfied:

[0098]

[0099] Therefore, the final length l of the pipeline is l o The sum of ε and ε, where ε is the correction amount. The present invention proposes a design method for the minimum pipeline length based on the minimum bending radius of the hydraulic pipeline and the relative position of the liquid distribution plate 3 and the drill box 2. Under the premise of ensuring the reliability of the hydraulic pipeline, the redundant length of the pipeline is reduced, the problem of hanging pipes can be effectively solved, the pressure loss and energy consumption of the hydraulic system can be effectively reduced, the working efficiency of the hydraulic system can be improved, and the service life of the pipeline can be extended.
