[0002] Anchor drill is a machine that uses liquid as working medium to transfer energy to achieve various processes. In the coal industry, anchor drills are often used to drill holes to complete the support of anchors or cables.

[0003] The anchor drilling rigs in the prior art generally adopt vertical single-body drilling rigs. Since they are relatively bulky, the drilling rigs have strict requirements on the professional quality of the operators during the drilling operation. The drilling rigs will topple over if they are not careful. In addition, the operation site also requires personnel to frequently move the drilling rigs, and the weight of the drilling rigs themselves will also increase the labor of the workers.

[0004] In this regard, some people have proposed installing a support frame at the bottom of the drilling rig.

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] like Figures 1 to 6As shown, the present invention provides a support frame for an anchor drilling rig, comprising: a support sleeve 5, which extends in a vertical direction, and is provided with a limiting socket 11 for inserting a drilling rig body 1 of the anchor drilling rig; a fixed platform 4, which is connected to the upper end of the support sleeve 5; a plurality of support rods 6, which are arranged at intervals around the outer circumference of the fixed platform 4, and the upper end of each support rod 6 is hinged to the fixed platform 4; a sliding pressure plate 14, which is slidably installed in the limiting socket 11 in the vertical direction and is located below the drilling rig body 1 to support the drilling rig body 1; a plurality of connecting rods 7, which are arranged one by one with the plurality of support rods 6, and one end of each connecting rod 7 is hinged to the sliding pressure plate 14 after passing through the support sleeve 5, and the other end of each connecting rod 7 is hinged to the middle part of the corresponding support rod 6.

[0031] In this way, the support frame for the anchor drilling rig of the present invention is a foldable structure, that is, it can be folded up when not in use to reduce the space it occupies, so as to facilitate its transportation and storage management. If a foldable structure is adopted, the drilling rig body 1 can be inserted into the limiting socket 11 of the support sleeve 5 when in use, so that the sliding pressure plate 14 bears the weight of the anchor drilling rig and slides downward along the support sleeve 5. In the process of the sliding pressure plate 14 moving downward, it will act on multiple connecting rods 7, so that the multiple connecting rods 7 support the multiple support rods 6, so as to open the multiple support rods 6 to form a stable support for the anchor drilling rig, effectively preventing the occurrence of the anchor drilling rig tipping phenomenon, and making the support frame for the anchor drilling rig of the present invention have sufficient stability during movement, thereby solving the problem that the foldable support frame in the prior art is not suitable for the complex working site environment underground.

[0032] Specifically, the lower end of the support sleeve 5 is closed and the upper end is open.

[0033] like Figures 1 to 6 As shown, a plurality of slide grooves 13 are vertically opened on the outer wall of the support sleeve 5, and the plurality of slide grooves 13 are arranged one-to-one corresponding to the plurality of connecting rods 7, and each slide groove 13 extends along the extension direction of the support sleeve 5, and each slide groove 13 is used for the corresponding connecting rod 7 to pass through, so as to guide the movement of the corresponding connecting rod 7 with the sliding pressure plate 14; and / or the fixed platform 4 is a hexagonal plate, and the outer peripheral surface of the fixed platform 4 includes three installation side surfaces arranged in pairs, and the number of support rods 6 is three, and the top ends of the three support rods 6 are hinged to the three installation side surfaces one-to-one; and / or the support frame for the anchor drilling rig includes a plurality of universal wheels 8, and the plurality of universal wheels 8 are installed one-to-one at the bottom of the plurality of support rods 6, so as to facilitate people to move the support frame for the anchor drilling rig of the present invention.

[0034] like Figures 1 to 3As shown, the support frame for the anchor drilling rig includes a water pipe reel 9 and / or an oil pipe reel 10, which are detachably mounted on a fixed platform 4; the water pipe reel 9 and / or the oil pipe reel 10 include: a fixed shaft 15 and a reel body 35 rotatably mounted on the fixed shaft 15; a clamping member 16, which is arranged at one end of the fixed shaft 15, and is clamped on the fixed platform 4 and located between any two adjacent support rods 6.

[0035] like Figure 3 As shown, the clamping member 16 includes a clamping block 36 and a fastener 37, and the clamping block 36 is provided with a mounting groove and an opening portion connected to the mounting groove, and one side of the fixing platform 4 is clamped into the mounting groove through the opening portion; wherein, one of the clamping block 36 and the fixing platform 4 is provided with a connecting hole 42 connected to the mounting groove for the threaded end of the fastener 37 to pass through, and the other of the clamping block 36 and the fixing platform 4 is provided with a threaded hole 12 for threaded connection with the threaded end of the fastener 37.

[0036] Since the drilling rig body 1 is in a constant state of movement within the operating range, it is necessary to ensure that there are sufficiently long water pipes and oil pipes. However, the on-site working environment in coal mines is complex. If the oil pipes and water pipes are all scattered on the ground, there is a safety hazard that people may be tripped by them when walking back and forth on the working surface. In addition, if equipment passes through the site, the oil pipes and water pipes may be damaged. Therefore, in order to better store and manage the oil pipes and water pipes, the water pipe reel 9 and the oil pipe reel 10 are installed on the fixed platform 4, so that the water pipes and oil pipes can be moved and released as the drilling rig body 1 moves, and they are avoided as much as possible from being scattered on the ground. When all the anchor drilling operations are completed, the water pipes and oil pipes can be all wound on the water pipe reel 9 and the oil pipe reel 10, which are very convenient to manage and use.

[0037] Specifically, the disc body 35 of the water pipe disc 9 and the oil pipe disc 10 can be rotated relative to the fixed shaft 15 to realize the winding or releasing of the water pipe and the oil pipe. When the anchor rod or anchor cable operation is completed, the water pipe can be wound on the water pipe disc 9 and the oil pipe can be wound on the oil pipe disc 10; in addition, the corresponding fasteners 37 can be removed to remove the water pipe disc 9 and the oil pipe disc 10 from the fixed platform 4.

[0038] like Figure 4 and Figure 5 As shown, the support rod 6 includes a sleeve 38 and a telescopic rod 26. The telescopic rod 26 is slidably inserted in the sleeve 38. A guide groove 27 is provided on the telescopic rod 26. The guide groove 27 is parallel to the telescopic direction of the telescopic rod 26. A sliding part 39 is provided in the sleeve 38 and is slidably connected to the guide groove 27.

[0039] like Figure 4 and Figure 5As shown, the sliding portion 39 includes: a limit block 31, which is slidably arranged in the guide groove 27 along the extension and contraction direction of the telescopic rod 26; a force plate 32, which is arranged on a side of the limit block 31 away from the bottom surface of the guide groove 27 and is fixedly connected to the limit block 31, and an insertion groove 34 is provided on the inner wall surface of the sleeve 38 for plugging and cooperating with the force plate 32, and the insertion groove 34 is fixedly connected to the insertion groove 34; two limit columns 33, which are located on a side of the limit block 31 close to the sleeve 38 and are fixedly connected to the sleeve 38, and the two limit columns 33 are spaced apart on opposite sides of the insertion groove 34 along the extension and contraction direction of the telescopic rod 26 to limit the movement of the force plate 32 relative to the sleeve 38 along the extension and contraction direction of the telescopic rod 26.

[0040] like Figure 4 and Figure 5 As shown, the support frame for the anchor drilling rig also includes a locking mechanism 40, which includes: an eccentric wheel mounting seat 28, an outer side of the support rod 6 is provided with an avoidance hole 41 connected to the plug-in slot 34, the eccentric wheel mounting seat 28 is installed on the sleeve 38 and the bottom of the eccentric wheel mounting seat 28 is connected to the plug-in slot 34 through the avoidance hole 41; an eccentric wheel 29, the eccentric wheel 29 is rotatably arranged on the eccentric wheel mounting seat 28 to cooperate with the force plate 32; a lever 30, the lever 30 is arranged on the side of the eccentric wheel 29 away from the telescopic rod 26 and is drivingly connected to the eccentric wheel 29; wherein, the eccentric wheel 29 is driven to abut or separate from the force plate 32 by toggling the lever 30, so as to lock or unlock the movement of the limit block 31 and the force plate 32 relative to the telescopic rod 26 along the telescopic direction of the telescopic rod 26.

[0041] In the actual production process, the underground tunnels may have ups and downs due to the complex geological conditions. Therefore, in order to enable the anchor drilling rig to carry out normal support operations in a tunnel with a certain slope, the support frame for the anchor drilling rig of the present invention sets at least one support rod 6 as a retractable structure, and sets a locking mechanism 40 to lock or unlock the telescopic movement of the support rod 6. When the drilling rig is supporting in a tunnel with a slope, the retractable support rod 6 is first rotated to the upper side of the tunnel, and the other two support rods 6 are located at the lower side of the tunnel; then, the eccentric wheel 29 is separated from the force plate 32 by toggling the toggle lever 30, and the friction between the limit block 31 and the guide groove 27 is reduced to limit the movement of the limit block 31. The block 31 and the force plate 32 are unlocked relative to the movement of the telescopic rod 26 along the telescopic direction of the telescopic rod 26; then the drilling rig body is tilted toward one side of the telescopic rod 26, and under the action of the gravity of the drilling rig body 1, the telescopic rod 26 will retract into the sleeve 38. After the entire drilling rig body 1 is in a vertical state relative to the horizontal plane, the lever 30 is reversely moved to make the eccentric wheel 29 apply pressure to the force plate 32, thereby squeezing the limit block 31, so that a huge friction force is generated between the limit block 31 and the guide groove 27, so as to lock the movement of the limit block 31 and the force plate 32 relative to the telescopic direction of the telescopic rod 26, thereby keeping the telescopic rod 26 and the sleeve 38 stationary.

[0042] In addition, since the drilling rig body 1 is on a slope, each universal wheel 8 of the support frame for the anchor drilling rig of the present invention is equipped with a brake structure to prevent the anchor drilling rig from sliding down the slope.

[0043] like Figures 6 to 8 As shown, the present invention further provides an anchor drilling rig, comprising a drilling rig body 1 and the above-mentioned support frame for the anchor drilling rig, wherein the support frame for the anchor drilling rig is used to support the drilling rig body 1.

[0044] like Figure 7 and Figure 8 As shown, the anchor drilling rig includes: a manipulator arm 2, which is hinged to the drilling rig body 1; a handle mounting rod 17, which is fixedly connected to one end of the manipulator arm 2 away from the drilling rig body 1; a fixed handle 19, which is fixedly connected to one end of the handle mounting rod 17, and the center line of the fixed handle 19 is collinear with the center line of the handle mounting rod 17; and a lifting control handle 18, which is rotatably connected to the other end of the handle mounting rod 17, and the center line of the lifting control handle 18 is collinear with the center line of the handle mounting rod 17.

[0045] In the anchor drilling rig of the present invention, the lifting control handle 18 is used to control the extension and retraction of the drilling rig body 1. Turning the lifting control handle 18 clockwise will extend the top of the drilling rig body 1, and turning the lifting control handle 18 counterclockwise will retract the top of the drilling rig body 1; the rotating control lever 20 is used to control the rotation of the top of the drilling rig body 1.

[0046] like Figure 7 and Figure 8 As shown, the anchor drilling rig includes: a rotary control lever 20, which is rotatably connected to the fixed handle 19; a water pipe connector 23, which is fixedly connected to the top of the handle mounting rod 17 through a vertical short rod 22, and one end of the water pipe connector 23 is connected to an external water supply system; a transition water pipe 3, one end of the transition water pipe 3 is connected to the other end of the water pipe connector 23, and the other end of the transition water pipe 3 is connected to the rotary output end at the top of the drilling rig body 1; a solenoid valve 24, which is installed at the water pipe connector 23, and a first contact 21 electrically connected to the solenoid valve 24 is provided on the rotary control lever 20, and a second contact 25 for contacting or disconnecting with the first contact 21 is provided on the fixed handle 19; wherein, the second contact 25 is contacted or disconnected with the first contact 21 by rotating the rotary control lever 20 to control the on and off of the solenoid valve 24.

[0047] During the operation of the anchor drilling rig, it is necessary to continuously supply water for the drilling operation to prevent the drill rod from being blocked. The middle part of the water pipe connector of the anchor drilling rig in the prior art is connected with a ball valve to control the on and off of the water supply. When drilling the anchor rod, first rotate the lifting control handle to drive the drill rod to rise to support the top plate of the working surface, and then turn the rotating control lever to position the drill rod to find the hole. Then the right hand needs to leave the lifting control handle to operate the valve handle of the ball valve to open the ball valve. After the drilling is completed, the personnel also need to move their hands away from the lifting control handle to operate the valve handle of the ball valve again. The operation process is not only cumbersome, but also forgetting to open the ball valve will cause poor water supply and blockage of the drill rod. In order to improve the above situation, the anchor drilling rig of the present invention is equipped with a solenoid valve 24 in the middle part of the water pipe connector 23, and the first contact 21 electrically connected to the solenoid valve 24 is connected to the position of the rotating control lever 20 near the outer end, and the fixed handle 19 is equipped with a first contact 21 electrically connected to the first contact The second contact 25 cooperates with the head 21. When operating the anchor drilling rig for drilling operations, hold the fixed handle 19 with the left hand, and rotate the lifting control handle 18 clockwise with the right hand to raise the drill rod to contact the top plate, and then turn the rotating control lever 20 to a certain angle (not to the bottom), first complete the positioning and hole finding, and then turn the rotating control lever 20 to the bottom, so that the first contact 21 and the second contact 25 are in contact and conductive, so that the solenoid valve 24 is energized and conductive, and the external water supply system can supply water to the inside of the drill rod through the transition water pipe 3, so that the personnel can always hold the fixed handle 19 and the lifting control handle 18 with both hands during the operation of the drilling rig, avoiding the trouble of the personnel's right hand leaving the lifting control handle 18 to operate the valve handle of the ball valve, thereby improving the safety of the operation, and will not cause the drill rod to be blocked due to forgetting to open the ball valve.

[0048] The use process of the anchor drilling machine of the present invention is as follows:

[0049] First, insert the drilling rig body 1 into the limiting socket 11 of the supporting sleeve 5, and the support frame for the anchor drilling rig will open under the gravity of the drilling rig body 1 and form a stable support for it; then fix the water pipe disc 9 and the oil pipe disc 10 on the fixed platform 4, one end of the wound water pipe on the water pipe disc 9 is connected to the external water supply system, and the other end is connected to the water pipe connector 23, and the oil pipe on the oil pipe disc 10 is connected to the oil pump; then start to operate the operating arm 2 to perform drilling operations. When drilling, first hold the fixed handle 19 with the left hand, and rotate the lifting control handle 18 clockwise with the right hand to raise the drill rod to contact with the top plate, and then turn the rotating control lever 20 to a certain angle for positioning and hole finding, and then turn the rotating control lever 20 to the bottom to make the first contact 21 and the second contact 25 contact and conduct, so that the solenoid valve 24 is turned on, so that the water supply system is turned on. Water is supplied inside the drill rod; then the lifting control handle 18 continues to be rotated clockwise to feed the drill rod forward. After drilling is completed, the left hand releases the rotating control lever 20 at a certain angle to separate the first contact 21 and the second contact 25 but still controls the anchor drill to maintain the output torque, so as to disconnect the solenoid valve 24 and stop the water supply; then the lifting control handle 18 is rotated counterclockwise to withdraw the drill rod. After completing the drilling operation of one station, the support frame for the anchor drill is pushed forward to move the anchor drill to the next station, and the water pipes and oil pipes on the water pipe disc 9 and the oil pipe disc 10 are released. After completing the drilling operation of all stations, all the water pipes and oil pipes are wound onto the water pipe disc 9 and the oil pipe disc 10, and then the drilling rig body 1 is removed from the limiting socket 11 of the support sleeve 5, and the sliding pressure plate 14 is pushed upward to fold the folding support frame.

[0050] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0051] The support frame for the anchor drilling rig of the present invention includes: a support sleeve 5, which extends in the vertical direction and is provided with a limiting socket 11 for inserting the drilling rig body 1 of the anchor drilling rig; a fixed platform 4, which is connected to the upper end of the support sleeve 5; a plurality of support rods 6, which are arranged at intervals around the outer circumference of the fixed platform 4, and the upper end of each support rod 6 is hinged to the fixed platform 4; a sliding pressure plate 14, which is slidably installed in the limiting socket 11 in the vertical direction and is located below the drilling rig body 1 to support the drilling rig body 1; a plurality of connecting rods 7, which are arranged one by one with the plurality of support rods 6, one end of each connecting rod 7 is hinged to the sliding pressure plate 14 after passing through the support sleeve 5, and the other end of each connecting rod 7 is hinged to the middle part of the corresponding support rod 6. In this way, the support frame for the anchor drilling rig of the present invention is a foldable structure, that is, it can be folded up when not in use to reduce the space it occupies, so as to facilitate its transportation and storage management. If a foldable structure is adopted, the drilling rig body 1 can be inserted into the limiting socket 11 of the support sleeve 5 when in use, so that the sliding pressure plate 14 bears the weight of the anchor drilling rig and slides downward along the support sleeve 5. In the process of the sliding pressure plate 14 moving downward, it will act on multiple connecting rods 7, so that the multiple connecting rods 7 support the multiple support rods 6, so as to open the multiple support rods 6 to form a stable support for the anchor drilling rig, effectively preventing the occurrence of the anchor drilling rig tipping phenomenon, and making the support frame for the anchor drilling rig of the present invention have sufficient stability during movement, thereby solving the problem that the foldable support frame in the prior art is not suitable for the complex working site environment underground.
