Description

Technical Field

[0001] The invention relates to the application field of coal mine tunnel drilling machines, in particular to a coal mine drilling machine capable of being adjusted at multiple working positions. Background Art

[0002] Coal mines are an important energy resource in my country. In order to efficiently mine and utilize coal resources, the use of drilling rigs plays an important role in coal mining. Commonly used drilling rigs in coal mines include core drills, rotary drills and anchor drills. Different types of drilling rigs for coal mines are divided into hydraulic, pneumatic, electric, etc. according to the power source. For example, the common pneumatic crawler drilling vehicle mainly consists of an all-terrain crawler vehicle, an angle adjustment mechanism and a drilling host. The crawler vehicle is used to drive the device to move in complex terrain. The angle adjustment mechanism can adjust the vertical height, horizontal position and elevation angle of the drilling host. The drilling host includes a frame, a drill rod drive device and a drill rod clamp. The drill rod drive device is used to drive the drill rod to rotate. The drill rod clamp can support the drill rod and limit its reversal. The bearing inside the drill rod clamp is a wear part. The drill rod is divided into a rod body and a rod head. The rod body is generally equipped with multiple groups and multiple groups of rod shafts and rod heads are threadedly connected to each other.

[0003] When the coal mine drilling rig is in use, the head of the rod head is installed in the drill rod clamp, and the tail of the rod body is installed in the drill rod driving device. The drill rod driving device is started to drive the rod body to rotate, and the driving assembly in the frame is started to drive the drill rod driving device to move, so that the rod body actively approaches the rod head, and the rod body and the rod head are threadedly connected to form a whole through rotation, and then the angle adjustment mechanism is adjusted to work so that the rod head is aligned with the specified position. In this way, the drill rod driving device drives the rod body and the rod head to rotate and push the rod body and the rod head to move to drill holes in the rock wall. When the rod head enters the rock wall, ensure that the tail of the rod head is still in the drill rod clamp. At this time, the length of a set of rod shafts and rod heads can no longer meet the drilling requirements, and then the drill rod driving device is reversed, and the drill rod clamp will limit the rotation of the rod head, and then the rod shaft and the rod head are separated, and the drill rod driving device is reset. At this time, another set of rod shafts can be installed between the rod shaft and the rod head. In this way, a deeper hole can be drilled in the rock wall by reciprocating.

[0004] The main machine of the coal mine drilling rig is the main working part for drilling holes. The main machine involves multiple installations of the rod body when drilling holes and multiple disassemblies of the rod body after drilling. When installing the rod body: the main steps are to separate the rod body in the drill rod driving device from the rod body in the drill rod clamp, and then install a new rod body between the two sets of rod bodies. The staff mainly relies on holding the new rod body and using a large wrench to thread it with the rod head or rod body in the drill rod clamp. The rod body is made of metal and has a certain weight. It is difficult to thread it by holding the rod body. Then the drill rod driving device drives the rod body inside to move and rotate it at the same time to make its head and the new rod body. The tail of the installed rod is threadedly connected. Here, the threaded connection between the rods is achieved by mechanical force. The rod in the drill rod driving device and the newly installed rod need to be ensured to be at the same level so that the two sets of rods can be perfectly threaded together. Usually, the connection of new equipment is relatively simple, while some old equipment, especially when the bearing bush in the drill rod holder is seriously worn, the newly installed rod drops at one end due to gravity, and then the rod in the drill rod driving device and the newly installed rod are not at the same level. At this time, the staff needs to manually calibrate by hand. The mechanical force of the equipment is large, and the staff has certain risks during calibration;

[0005] When disassembling the rod shaft: Since the drill rods in the rock wall are heavy and the friction between the drill rods and the rock wall is large, it is not feasible to manually pull them out section by section and then disassemble them. Therefore, it is necessary to use the drill rod driving device to retreat to drive multiple rod shafts and rod heads in the rock wall to be pulled out and disassembled in sections. The process of rod shaft disassembly is the opposite of the process of rod shaft installation. By adjusting the drill rod driving device to retreat, the drill rod driving device fixes the last rod shaft at this time, and the drill rod clamp fixes the third-to-last rod shaft, and then the second-to-last rod shaft is disassembled. Usually, the staff holds a large wrench, uses the frame of the rack as a fulcrum, and uses the lever principle to fix the second-to-last rod shaft. Then the drill rod driving device drives the last rod shaft to reverse, first separating the second-to-last rod shaft from the last rod shaft, and then the staff continues to use a large wrench to remove the second-to-last rod shaft from the third-to-last rod shaft in the drill rod clamp. It is time-consuming and laborious to mainly rely on manual methods to remove the rod shafts. After removing one rod shaft, multiple rod shafts in the rock wall still need to be pulled out, which cannot be done well by manpower. Therefore, the drill rod driving device moves again and rotates forward, so that the last rod shaft is re-connected to the rod shaft thread in the drill rod clamp, and then retreats and pulls it out again, and continues to remove the rod shafts in the same way as above, and the disassembly speed is slow.

[0006] The installation and removal of the rod shaft mainly rely on manual assistance, and there are no good auxiliary tools, which makes the installation and removal of the drill rod time-consuming, laborious, and dangerous. Summary of the invention

[0025] Preferably, a through slot is provided so that the second rod shaft can pass through the frame.

[0026] In summary, the present invention mainly has the following beneficial effects:

[0027] 1. The present invention can be used to support the rod shaft and limit its rotation by arranging a hexagonal head clamping assembly and a rod body clamping assembly. The lifting assembly has the function of pre-loading the rod shaft, and the lifting assembly can lift the rod shaft to between the drill rod driving chuck and the drill rod clamp. The hexagonal head clamping assembly limits the rotation of the rod shaft, so that the drill rod driving chuck drives the rod shaft inside it to rotate and move, and can be threadedly connected with the later installed rod shaft more quickly and efficiently, and the later installed rod shaft can move left and right in the lifting assembly, and then when the drill rod driving chuck drives the rod shaft inside it and the later installed rod shaft to move and rotate, it can be directly threadedly connected with the rod shaft in the drill rod clamp. With the help of the hexagonal head clamping assembly, the rod body clamping assembly and the lifting assembly, the staff can improve the installation efficiency of the rod shaft and improve the safety of the rod shaft installation.

[0028] 2. The present invention can improve the work efficiency and safety of rod shaft disassembly by arranging a drill rod disassembly assembly. The drill rod disassembly assembly has the function of locking two groups of rod shafts at the same time and can also lock the rod shafts separately and independently. Therefore, the drill rod disassembly assembly first locks the rod shafts in the drill rod driving chuck and the second to last rod shaft to ensure that the drill rod driving chuck rotates, which will separate the last two groups of rod shafts from the third to last rod shaft. Then, the drill rod disassembly assembly is used to separate the last two rod shafts. During disassembly, the staff only needs to adjust the drill rod disassembly assembly, and there is no need to use a wrench for manual disassembly. The staff does not have direct contact with the rod shaft, which improves the disassembly efficiency while ensuring the personal safety of the staff.

[0029] 3. The present invention can be used to connect drill rods in a separated state by providing a drill rod disassembly assembly. In actual applications, after a group of rod shafts are disassembled, the rod shafts in the drill rod driving chuck need to be re-threadedly connected with the rod shafts in the drill rod clamp, and the remaining rod shafts are continued to be pulled out with the help of the retreat of the drill rod driving chuck. However, after the drill rod disassembly assembly is provided, the re-threading process can be omitted. The drill rod disassembly assembly only needs to lock the head of the rod shaft in the drill rod driving chuck and the tail of the rod shaft in the drill rod clamp respectively, and the rod shaft pulling work can be started directly, thereby improving the disassembly efficiency.

[0058] In the above embodiments, please refer to Figure 10-16 The drill rod disassembly assembly 15 includes two sets of fixed seats 1501, and the interior of the fixed seats 1501 is provided with an annular groove 1502, and the interior of the two sets of fixed seats 1501 is rotatably connected with a circular block 1503, the exterior of the two sets of circular blocks 1503 is provided with an outer convex ring 1504 matching the annular groove 1502, and the interior of the circular block 1503 is movably installed with two sets of third clamping blocks 1506 by setting a third guide rail assembly 1505, and the two sets of third clamping blocks 1506 are symmetrically arranged, the interior of the two sets of circular blocks 1503 is rotatably connected with a second positive and negative threaded rod 1507 and a transmission shaft 1508, and the second positive and negative threaded rod 1507 and the transmission shaft 1508 are transmission-connected by setting a worm gear assembly 1509, and the second positive and negative threaded rod 1 507 is threadedly connected with two groups of third clamping blocks 1506, the sides of the two groups of circular blocks 1503 are provided with external gear rings 1510, and the two groups of circular blocks 1503 are fixedly connected by setting multiple groups of connecting rods 1514, the sides of the two groups of fixed seats 1501 are movably installed with U-shaped clips 1511 by setting slide rails, and the ends of the U-shaped clips 1511 are provided with arc-shaped racks 1512 matching the external gear rings 1510, and the sides of the fixed seats 1501 are rotatably connected with third threaded rods 1513, and the third threaded rods 1513 and the U-shaped clips 1511 are threadedly connected. By setting the drill pipe disassembly assembly 15, the staff can be assisted to disassemble the first shaft 4, the second shaft 17 and the rod head 5 of the drill pipe respectively, and the operation is more efficient and safer than working with a wrench.

[0059] In the above embodiments, please refer to Figure 8 and Fig.16 A plurality of groups of bar teeth 16 are arranged on the inner side of the first clamping block 1103 and the third clamping block 1506. By arranging the bar teeth 16 in the first clamping block 1103 and the third clamping block 1506, the first clamping block 1103 and the third clamping block 1506 have a better clamping effect on the hexagonal head of the first shaft 4, the second shaft 17 and the club head 5. A plurality of groups of bar teeth 16 are arranged, so that the edge part of the hexagonal head can be more easily engaged between the two groups of bar teeth 16, thereby improving the clamping force.

[0060] In the above embodiments, please refer to Figure 2 A through slot 9 is provided on the top of the frame 6 , and the through slot 9 matches the length of the second rod 17 . By providing the through slot 9 , the second rod 17 can pass through the frame 6 .

[0061] The present invention is used in specific operation: when a drilling machine is needed to drill a hole in a rock wall, the first rod shaft 4 is first installed into the drill rod driving chuck 2, the rod head 5 is installed into the drill rod clamp 3, the drill rod clamp 3 is started to lock the rod head 5, and then the driving assembly 8 is started to drive the drill rod driving chuck 2 to approach the drill rod clamp 3, and at the same time, the drill rod driving chuck 2 is started to drive the first rod shaft 4 to rotate slowly, and then the threaded head at the end of the first rod shaft 4 will be threadedly connected with the hexagonal head at the end of the rod head 5. After the threaded connection is completed, the drill rod clamp 3 is released to the rod The head 5 is locked, and the drill rod driving chuck 2 drives the first rod shaft 4 and the rod head 5 to rotate slowly together. Then the multi-station angle adjustment machine base 1 is started, and the vertical height, horizontal position and elevation angle of the frame 6 are adjusted to make the drill bit at the end of the rod head 5 aim at the specified area. Then the rotation speed of the drill rod driving chuck 2 is increased, so that the drill rod driving chuck 2 drives the first rod shaft 4 and the rod head 5 to rotate quickly. At the same time, the driving assembly 8 is kept working to push the drill rod driving chuck 2 slowly close to the rock wall, and then the drill bit at the end of the rod head 5 will drill a hole in the rock wall.

[0062] During the process of opening the drill bit at the end of the rod head 5, the staff installs another set of second rod shafts 17 into the hexagonal head clamping assembly 11 and the rod body clamping assembly 12, so that the hexagonal head at the end of the second rod shaft 17 is engaged in the hexagonal head clamping assembly 11, and the threaded head at the end of the second rod shaft 17 is engaged in the rod body clamping assembly 12, and a small socket wrench is used to appropriately rotate the first forward and reverse threaded rod 1102, and the two sets of first clamping blocks 1103 are brought close to each other by utilizing the screw principle, so that the two sets of first clamping blocks 1103 clamp the hexagonal head of the second rod shaft 17, and one end of the threaded head of the second rod shaft 17 is directly engaged between the two sets of second clamping blocks 1203, and the two sets of second clamping blocks 1203 will clamp the rod body of the second rod shaft 17 under the resetting action of the second guide rail assembly 1204.

[0063] As the rod head 5 continues to go deeper into the rock wall, until the tail of the rod head 5, that is, the end of the hexagonal head, is still a short distance away from moving into the drill rod clamp 3, the drill rod drive chuck 2 is started to slowly reverse. When the drill rod clamp 3 detects that the rod head 5 has a tendency to reverse, it will automatically lock, and then the first rod shaft 4 and the rod head 5 are released from the threaded connection and separated, and then the drive assembly 8 is driven in reverse, so that the drill rod drive chuck 2 drives the first rod shaft 4 to retreat to the initial position. Next, the staff rotates the first threaded rod 1004, and uses the screw principle to make the first mounting plate 1003 rise outside the second guide rod 1002, thereby pushing the second mounting plate 1006 to rise, that is, pushing the second rod shaft 17, the first rod shaft 4 and the rod head 5 are at the same horizontal height, and then the drill rod driving chuck 2 is started to rotate slowly, and the driving assembly 8 is started to drive the drill rod driving chuck 2 to move, so that the first rod shaft 4 rotates and approaches the second rod shaft 17, so that the threaded head of the first rod shaft 4 and the hexagonal head of the second rod shaft 17 are threadedly connected together. After the connection is completed, the drill rod driving chuck 2 is stopped, and then the driving assembly 8 is started again to move the drill rod driving chuck 2 to push the first rod shaft 4 and the second rod shaft 17 to approach the rod head 5 until the threaded head of the second rod shaft 17 fits the hexagonal head of the rod head 5. During the movement of the first rod shaft 4 and the second rod shaft 17, because the hexagonal head clamping assembly 11 still maintains the second rod shaft The hexagonal head 17 is locked, and then the hexagonal head clamping assembly 11, the rod body clamping assembly 12 and the second mounting plate 1006 will move with the second rod shaft 17, and then the rod body clamping assembly 12 always maintains the support function for the rod body of the second rod shaft 17 to prevent the threaded head end of the second rod shaft 17 from deviating downward due to gravity. The second mounting plate 1006 will slide outside the third guide rod 1005 and compress the first spring 1007. When the threaded head of the second rod shaft 17 fits the hexagonal head of the rod head 5, the restriction of the first clamping block 1103 on the second rod shaft 17 is released, and at the same time, the drill rod driving chuck 2 is started to drive the first rod shaft 4 and the second rod shaft 17 to rotate slowly, so that the second rod The threaded head of the body 17 will be threadedly connected with the hexagonal head of the rod head 5. Next, according to the above, the lifting assembly 10 drives the hexagonal head clamping assembly 11 and the rod body clamping assembly 12 to descend, and then the rotation speed of the drill rod driving chuck 2 is increased, and the driving assembly 8 drives the drill rod driving chuck 2 to move, so that the first rod shaft 4, the second rod shaft 17 and the rod head 5 continue to go deeper into the rock wall, and the second rod shaft 17 and the rod head 5 move and rotate in the drill rod clamp 3. Therefore, the bearing bushing in the drill rod clamp 3 is a wearing part. Until the tail of the second rod shaft 17, that is, the end of the hexagonal head, has not moved a short distance into the drill rod clamp 3, it is necessary to install another set of second rod shafts 17 again, and the steps are the same as above.

[0064] When the drill rig needs to take out the drill rod after drilling, the drill rod driving chuck 2 is in a state close to the drill rod clamp 3. The drill rod driving chuck 2 is closed, and the driving assembly 8 is started in reverse to make the drill rod driving chuck 2 retreat to the initial position. The staff pushes the moving assembly 14 to slide in the limiting groove 13, thereby moving the position of the drill rod removal assembly 15 to the connection between the first rod shaft 4 and the second rod shaft 17, and rotating the second threaded rod 1405 to use the screw principle to make the fourth guide rod 1403 slide in the first fixed plate 1402, that is, to push the second fixed plate 1404 close to the first rod shaft 4 and the second rod shaft 17, thereby pushing the drill rod removal assembly 15 close to the first rod shaft 4 and the second rod shaft 17, so that a group of circular blocks 1503 in the drill rod removal assembly 15 are engaged with one end of the threaded head of the first rod shaft 4, and another group of circular blocks 1503 in the drill rod removal assembly 15 are engaged with the second rod shaft 1 7, and then use a small socket wrench to rotate the two sets of transmission shafts 1508 respectively, and drive the second forward and reverse threaded rod 1507 to rotate through the worm gear assembly 1509, and use the screw principle to make the two sets of third clamping blocks 1506 approach each other, so as to clamp the first rod shaft 4 and the second rod shaft 17, and the two sets of circular blocks 1503 are connected as a whole under the action of the connecting rod 1514, and the two sets of third threaded rods 1513 are rotated, and the U-shaped card 1511 is slid by the screw principle, so that the arc rack 1512 is away from the outer gear ring 1510, and the first rod shaft 4 and the second rod shaft 17 are further locked as a whole under the action of the drill rod disassembly assembly 15, and then the drill rod driving chuck 2 is started to drive the first rod shaft 4 and the second rod shaft 17 to slowly reverse, and the drill rod clamp 3 locks the rod head 5, so that the second rod shaft 17 and the rod head 5 are released from the threaded connection and separated.

[0065] Next, the two groups of third threaded rods 1513 are rotated to make the arc-shaped rack 1512 fit the outer gear ring 1510, that is, the two groups of circular blocks 1503 are locked so that they cannot rotate, and then the two groups of third clamping blocks 1506 that clamp the first rod shaft 4 are released. The second rod shaft 17 is still clamped by the two groups of third clamping blocks 1506 in the other group of circular blocks 1503. The drill rod driving chuck 2 is started to drive the first rod shaft 4 to rotate slowly, thereby releasing the threaded connection between the first rod shaft 4 and the second rod shaft 17 and separating them. At this time, both ends of the second rod shaft 17 are separated, and the second rod shaft 17 can be directly taken out by the worker. However, at this time, the rod head 5 is still in the rock wall and is difficult to pull out. The driving assembly 8 is started to drive the drill rod driving chuck 2 to move, so that the first rod shaft 4 and the second rod shaft 17 are The rod shaft 4 is fitted with the rod head 5, and at the same time, the moving assembly 14 is pushed to drive the drill rod disassembly assembly 15 to move to the position where the first rod shaft 4 and the rod head 5 are fitted. Then, according to the above method, the third clamping block 1506 of the two groups of circular blocks 1503 in the drill rod disassembly assembly 15 is controlled to clamp the first rod shaft 4 and the rod head 5 respectively, that is, the drill rod disassembly assembly 15 connects the first rod shaft 4 and the rod head 5 as a whole, and the first rod shaft 4 and the rod head 5 do not need to be re-threaded. The drill rod driving chuck 2 is retracted to pull the rod head 5 out of the rock wall, and then the staff can remove the first rod shaft 4 and the rod head 5 respectively. If multiple groups of the second rod shaft 17 are installed during the use of the drilling rig, they can be disassembled and assembled in the same way as above.
