Description

Technical Field

[0001] This invention relates to the field of coal mine production tools technology, and in particular to a stabilizing base for a coal mine anchor cable drilling rig. Background Technology

[0002] With the improvement of coal mining capacity, the number of advanced large-scale equipment introduced by coal mines has increased, and the size of the roadways under construction has increased. Large-section roadways are excavated in a segmented bench manner. During the construction of anchor cables, the base of the mining pneumatic anchor drilling rig (model: MQT-130 / 3.2) cannot be effectively supported, the anchor drilling rig is prone to tipping over, and the angle of anchor cable drilling cannot be guaranteed, which affects the roadway support strength and the labor intensity of the workers.

[0003] The original drilling rig base has only one conical fixing device at the end (cone size: Φ30mm), which cannot guarantee the stability of the anchor cable drilling rig during operation, causing many inconveniences to the on-site anchor cable construction work. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a stable base for a coal mine anchor drilling rig, which solves the technical problem that the base of a mining pneumatic anchor drilling rig cannot be effectively supported in the mine.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0008] This invention provides a stabilizing base for a coal mine anchor drilling rig, comprising a horizontally arranged support plate supporting the lower end of the anchor drilling rig and a three-legged folding bracket disposed at the lower end of the support plate. The three-legged folding bracket includes three coal-inserting legs evenly spaced circumferentially at the lower end of the support plate and folded and stored therein. The lower ends of the coal-inserting legs are conical and inserted into the coal seam. An extension panel is rotatably connected to the periphery of the support plate via hinges, folded and stored between adjacent coal-inserting legs and parallel to the lower end face of the support plate. The extension panel rotates and abuts against the side end of the support plate and is flush with the upper and lower ends of the support plate. A support tool is inserted at the lower end of the extension panel to abut against the coal seam.

[0009] This invention provides a stabilizing base for a coal mine anchor drilling rig. When using this stabilizing base, the three coal-inserting legs at the lower end of the support plate rotate outward, allowing them to partially insert into the coal seam. Then, the extension panel is rotated to abut against the side end of the support plate. Supporting fixtures are then inserted into the lower end of the extension panel. Finally, the anchor drilling rig is installed and fixed to the upper surface of the support plate. By expanding the horizontal width of the support plate through the extension panel, and in conjunction with the coal-inserting legs inserting into the coal seam, sufficient support strength is provided to the anchor drilling rig. At the same time, the anchor drilling rig will not shift horizontally due to vibration, making it safer.

[0010] Optionally, the upper surface of the support plate is provided with three sets of first reinforcing grooves, and one end surface of the extension panel is provided with a set of second reinforcing grooves connected to the first reinforcing grooves. The first reinforcing grooves and the second reinforcing grooves are connected to each other and a first reinforcing connecting rod is embedded in them. The two ends of the first reinforcing connecting rod abut against the ends of the first reinforcing groove and the second reinforcing groove that are far apart from each other.

[0011] By creating a first reinforcing groove on the support base plate and a second reinforcing groove on the extension panel, the first and second reinforcing grooves connect when the extension panel rotates to abut against the side end of the support base plate. At this time, the same first reinforcing connecting rod is inserted into the first and second reinforcing grooves and fixed in place. This ensures that when the anchor drilling rig is installed and fixed to the upper surface of the support base plate, the connection between the extension panel and the support base plate will not undergo significant deformation when the support tool at the lower end of the extension panel provides support, thereby improving its structural strength and support effect.

[0012] Optionally, the lower end face of the support plate is provided with three sets of third reinforcing grooves, and one end face of the extension panel is provided with a fourth reinforcing groove communicating with the third reinforcing grooves. The support plate and the extension panel are respectively provided with connecting grooves at the ends of the third reinforcing grooves and the fourth reinforcing grooves that are far apart from each other. A second reinforcing connecting rod is embedded in both the third reinforcing groove and the fourth reinforcing groove. Connecting rods embedded in the connecting grooves are provided at both ends of the second reinforcing rod.

[0013] By creating a third reinforcing groove on the lower end face of the support plate and a fourth reinforcing groove on one end of the extension panel, and simultaneously creating a vertical connecting groove at the ends of the third and fourth reinforcing grooves that are far apart from each other, the connecting rods at both ends will be embedded in the connecting grooves when the second reinforcing connecting rod is inserted. This connects the support plate and the extension panel into a whole, reduces the degree of stress deformation at the connection between the extension panel and the support plate, and thus improves the support effect on the anchor drilling rig.

[0014] Optionally, the first reinforcing groove and the third reinforcing groove are misaligned, the second reinforcing groove and the fourth reinforcing groove are misaligned, the second reinforcing rod is magnetically attracted to the inside of the third reinforcing groove and the fourth reinforcing groove, and sealing plates with limiting first reinforcing rod and second reinforcing rod are respectively fixed on both ends of the extended panel.

[0015] By misaligning the first and third reinforcing grooves, and the second and fourth reinforcing grooves, the strength of the extended panel and the support plate is maintained. At the same time, the first and second reinforcing connecting rods are fixed by the sealing plate, ensuring the stability of the entire stable base when the anchor drilling rig is working.

[0016] Optionally, a limiting plate can be detachably connected to the lower end of the support base plate. The limiting plate is parallel to the support base plate and limits the coal insertion leg and the extension panel to a folded storage state.

[0017] By detachably installing a limiting plate at the lower end of the support base plate, when transporting the entire stable base, the extension panel and coal insertion legs can be folded up and the limiting plate can be directly fixed. This limits the extension panel and coal insertion legs, preventing them from rotating and opening, thus facilitating the transportation of the stable base.

[0018] Optionally, a protective sponge layer is provided on one end face of the limiting plate that abuts against the coal inserting leg and the extension panel, and the limiting plate is detachably connected to the support base plate.

[0019] By setting a protective sponge layer on one end face of the limiting plate, when the limiting plate limits the extension panel and the coal insertion leg, the extension panel and the coal insertion leg directly sink into the protective sponge layer, avoiding collisions caused by slight rotation, thus making it safer.

[0020] Optionally, a grinding disc is vertically slidable and rotatably mounted on one end face of the limiting disc away from the support base plate. The grinding disc is parallel to the support base plate and has the same diameter as the support base plate. Grinding protrusions are evenly arrayed on the lower end face of the grinding disc. A level is mounted on the upper end face of the support base plate near the edge.

[0021] By vertically sliding and rotating the grinding disc on the lower end face of the limiting plate, when the stable base is supported, the three extended panels are first rotated out and supported and fixed by the support props. At this time, observe the level on the upper end face of the support base plate and keep it in a horizontal state. Then, start the grinding disc and grind the surface of the coal seam to a horizontal state through the grinding protrusions on the lower end face of the grinding disc. Then, disassemble the limiting plate together with the grinding disc and support the entire stable base, so that the support of the stable base is more stable and firm.

[0022] Optionally, a sliding seat is provided at the lower end of the limiting plate, and a sliding hole is vertically opened in the middle of the sliding seat. A sliding column is vertically slidably inserted in the sliding hole. The grinding disc is located at the lower end of the sliding column. The sliding column has a built-in motor that drives the grinding disc to rotate. The sliding seat is rotatably provided with drive gears on both sides of the sliding hole to adjust the vertical movement of the sliding column.

[0023] The sliding column is directly driven to move vertically by the drive gear on the sliding seat. The sliding column drives the grinding disc to move vertically. After the support plate is supported by the three extended panels, the grinding disc gradually approaches the coal seam surface for grinding, which is more convenient.

[0024] Optionally, the support device includes support cross blocks arranged sequentially from top to bottom and fixing bolts that vertically pass through and fix the support cross blocks to the lower end of the extension panel. The support cross blocks have the same thickness and their volume gradually increases from top to bottom. The upper end of the support cross block is provided with a support groove for the upper-level support cross block to be partially embedded. The middle of the support cross block is provided with a through hole for the fixing bolt to pass through.

[0025] By arranging the cross support blocks sequentially and fixing them to the extension panel with fixing bolts, it is more convenient to select the appropriate number of support cross blocks on site as needed. At the same time, setting the cross blocks to gradually increase in size from top to bottom can also provide a more stable support effect.

[0026] Optionally, the support tool may further include an enlarged support plate fixed by the fixing bolt and located at the lower end of the support cross block at the lowest side. The enlarged support plate is circular and has a uniform array of nails inserted into the coal seam on its lower end surface.

[0027] By fixing an enlarged support plate to the lower end of the support cross block on the lowest side, the contact area between the enlarged support plate and the coal seam is increased, thereby improving the support effect. The lower end face of the enlarged support plate is arrayed with nails, which, together with the three-leg folding bracket, stabilizes the support effect and prevents displacement.

[0028] (III) Beneficial Effects

[0029] The beneficial effects of this invention are as follows: The coal mine anchor drilling rig stabilizing base of this invention allows the three coal-inserting legs at the lower end of the support base plate to rotate out, so that the three coal-inserting legs are partially inserted into the coal seam. Then, the expansion panel is rotated to abut against the side end of the support base plate. Then, a support tool is inserted into the lower end of the expansion panel. Finally, the anchor drilling rig is installed and fixed to the upper surface of the support base plate. By expanding the horizontal width of the support base plate through the expansion panel, and in conjunction with the coal-inserting legs being inserted into the coal seam, sufficient support strength is provided to the anchor drilling rig. At the same time, the anchor drilling rig will not shift in the horizontal direction due to vibration, making it safer. Attached Figure Description

[0036] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] The anchor bolt drilling rig stabilizing base proposed in this embodiment of the invention allows the three coal-inserting legs at the lower end of the support base plate to rotate out, partially inserting into the coal seam. Then, the extension panel is rotated to abut against the side of the support base plate. Supporting fixtures are then inserted into the lower end of the extension panel. Finally, the anchor bolt drilling rig is installed and fixed to the upper surface of the support base plate. By expanding the horizontal width of the support base plate through the extension panel, and in conjunction with the coal-inserting legs inserting into the coal seam, sufficient support strength is provided to the anchor bolt drilling rig. Simultaneously, the anchor bolt drilling rig will not shift horizontally due to vibration, making it safer.

[0038] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although 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 to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0039] Reference Figures 1-4 A stabilizing base for a coal mine anchor drilling rig includes a support plate 1 horizontally arranged and supported at the lower end of the anchor drilling rig, and a three-legged folding bracket 2 disposed at the lower end of the support plate 1. The three-legged folding bracket 2 includes three coal-inserting legs 22 that are evenly spaced around the lower end of the support plate 1 and folded and stored therein. The lower ends of the coal-inserting legs 22 are cone-shaped and inserted into the coal seam. An extension panel 3 is rotatably disposed on the periphery of the support plate 1, folded and stored between adjacent coal-inserting legs 22 and parallel to the lower end face of the support plate 1. The extension panel 3 rotates and abuts against the side end of the support plate 1 and is flush with the upper and lower end faces of the support plate 1. A support tool 4 is inserted at the lower end of the extension panel 3 and abuts against the coal seam.

[0040] When using this stable base, the three coal-inserting legs 22 at the lower end of the support plate 1 are rotated out, so that the three coal-inserting legs 22 are partially inserted into the coal seam. Then, the extension panel 3 is rotated until it abuts against the side end of the support plate 1. Then, the support prop 4 is inserted into the lower end of the extension panel 3. Finally, the anchor drill is installed and fixed to the upper surface of the support plate 1. The horizontal width of the support plate 1 is expanded by the extension panel 3. With the coal-inserting legs 22 inserted into the coal seam, sufficient support strength is provided to the anchor drill. At the same time, the anchor drill will not shift in the horizontal direction due to vibration, making it safer.

[0041] The three-legged folding bracket 2 also includes a rotating seat 21 fixed to the lower end face of the support base plate 1 by bolts. The three rotating seats 21 are evenly spaced in the circumference, and the three coal inserting legs 22 are rotatably connected to the rotating seats 21 by rotating shafts.

[0042] The upper surface of the support base plate 1 has three sets of first reinforcing grooves 11, and one end surface of the extension panel 3 has a set of second reinforcing grooves 31 that connect to the first reinforcing grooves 11. A first reinforcing connecting rod 32 is embedded in both the interconnected first and second reinforcing grooves 11 and 31. The two ends of the first reinforcing connecting rod 32 abut against the opposite ends of the first and second reinforcing grooves 11 and 31, respectively. When the extension panel 3 rotates to abut against the side of the support base plate 1, the first and second reinforcing grooves 11 and 31 connect. At this time, the same first reinforcing connecting rod 32 is inserted into and fixed in the first and second reinforcing grooves 11 and 31. This ensures that when the anchor drilling rig is installed and fixed to the upper surface of the support base plate 1, the connection between the extension panel 3 and the support base plate 1 will not undergo significant deformation when the support fixture 4 at the lower end of the extension panel 3 provides support, thereby improving its structural strength and support effect.

[0043] The lower end face of the support plate 1 has three sets of third reinforcing grooves 12. One end face of the extension panel 3 has a fourth reinforcing groove 33 that communicates with the third reinforcing grooves 12. The support plate 1 and the extension panel 3 each have a connecting groove 34 perpendicularly formed at the ends of the third reinforcing grooves 12 and 33 that are far apart from each other. A second reinforcing connecting rod 35 is embedded in both the third reinforcing grooves 12 and 33. Both ends of the second reinforcing rod are integrally and perpendicularly provided with connecting rods 36 that are embedded in the connecting grooves 34. When the second reinforcing connecting rod 35 is inserted, the connecting rods 36 at both ends will be embedded in the connecting grooves 34, thereby connecting the support plate 1 and the extension panel 3 into a whole, reducing the degree of stress deformation at the connection between the extension panel 3 and the support plate 1, and thus improving the support effect on the anchor drilling rig.

[0044] The first reinforcing groove 11 and the third reinforcing groove 12 are misaligned, the second reinforcing groove 31 and the fourth reinforcing groove 33 are misaligned, the second reinforcing rod is magnetically attracted to the inside of the third reinforcing groove 12 and the fourth reinforcing groove 33, and the end plates 37 of the expansion panel 3 are magnetically fixed to the limiting first reinforcing link 32 and the second reinforcing link 35 respectively.

[0045] The upper surface of the support plate 1 is provided with a storage groove 16 for the first reinforcing link 32 and the second reinforcing link 35 to be embedded and fixed.

[0046] A limiting plate 13 is detachably connected to the lower end of the support base plate 1 via bolts. The limiting plate 13 is parallel to the support base plate 1 and limits the coal insertion leg 22 and the extension panel 3 to a folded and stored state. By detachably setting the limiting plate 13 at the lower end of the support base plate 1, when transporting the entire stable base, after folding the extension panel 3 and the coal insertion leg 22, the limiting plate 13 is directly fixed, thereby limiting the extension panel 3 and the coal insertion leg 22 to prevent them from rotating and opening, thus facilitating the transportation of the stable base.

[0047] The limiting plate 13 has a protective sponge layer 131 on one end face that abuts against the coal inserting leg 22 and the extension panel 3. The limiting plate 13 is detachably connected to the support base plate 1. When the limiting plate 13 limits the extension panel 3 and the coal inserting leg 22, the extension panel 3 and the coal inserting leg 22 are directly embedded in the protective sponge layer 131, avoiding collisions caused by slight rotation, thus making them safer.

[0048] When the anchor drilling rig is fixed on the upper surface of the support plate 1, the limiting plate 13 can also abut against the coal seam surface to provide support.

[0049] A grinding disc 5 is vertically slidable and rotated on the end face of the limiting plate 13 away from the support plate 1. The grinding disc 5 is parallel to the support plate 1 and has the same diameter as the support plate 1. Grinding protrusions 51 are evenly arranged on the lower end face of the grinding disc 5. A level 14 is installed on the upper end face of the support plate 1 near the edge. When the stable base is erected, the three extended panels 3 are first rotated out and supported by the support prop 4. At this time, the level 14 on the upper end face of the support plate 1 is observed and kept horizontal. Then, the grinding disc 5 is started, and the surface of the coal seam is ground to a horizontal state through the grinding protrusions 51 on the lower end face of the grinding disc 5. Then, the limiting plate 13 and the grinding disc 5 are disassembled together, and the entire stable base is erected, so that the support of the stable base is more stable and firm.

[0050] The lower end of the limiting plate 13 is detachably fixed to a sliding seat 15 by bolts. A sliding hole 151 is vertically opened in the middle of the sliding seat 15. A sliding column 152 is vertically slidably inserted in the sliding hole 151. The grinding plate 5 is fixed to the lower end of the sliding column 152 by bolts. The sliding column 152 has a motor that drives the grinding plate 5 to rotate. The sliding seat 15 has through holes on both sides of the sliding hole 151 that connect to the sliding hole 151. The sliding seat 15 has a motor fixed to the outside of the through holes by bolts. The output shaft of the motor is keyed to a drive gear 153. A drive rack is provided on each of the two ends of the sliding column 152 along the length direction. The two drive gears 153 are partially embedded in the through holes and mesh with the drive racks, thereby driving the sliding column 152 to move vertically by the motor. The sliding column 152 is directly driven to move vertically by the drive gear 153 on the sliding seat 15. The sliding column 152 drives the grinding disc 5 to move vertically. After the three extended panels 3 support the support base plate 1, the grinding disc 5 gradually approaches the coal seam surface and performs grinding, which is more convenient.

[0051] The support device 4 includes support cross blocks 41 arranged sequentially from top to bottom, and fixing bolts 42 vertically inserted to fix the support cross blocks 41 to the lower end of the extension panel 3. The support cross blocks 41 have the same thickness and gradually increase in volume from top to bottom. The upper end of the support cross block 41 has a support groove 411 for the upper-level support cross block 41 to be partially inserted, and the middle of the support cross block 41 has a vertical through hole 412 for the fixing bolt 42 to pass through. By arranging the cross support blocks sequentially and fixing them to the extension panel 3 with the fixing bolts 42, the appropriate number of support cross blocks 41 can be selected on-site as needed, which is more convenient. At the same time, setting the cross blocks to gradually increase in size from top to bottom can also provide a more stable support effect.

[0052] The support fixture 4 also includes an enlarged support plate 43 fixed by fixing bolts 42 and located at the lower end of the bottommost support cross block 41. The enlarged support plate 43 is circular and has a uniform array of anchor bolts 431 inserted into the coal seam on its lower end surface. The enlarged support plate 43 increases the contact area with the coal seam, thereby improving the support effect. The anchor bolts 431 arranged in an array on the lower end surface of the enlarged support plate 43, in conjunction with the three-legged folding bracket 2, provide stable support and prevent displacement.
