Description

Technical Field

[0001] This invention relates to the field of downhole operation equipment technology, specifically a portable casing installation machine. Background Technology

[0002] In underground mining environments such as coal mines, there is a certain amount of combustible gas. In order to ensure the normal progress of various construction projects and the personal safety of workers, it is necessary to remove combustible gas from the mine roadways. The existing method for removing combustible gas involves opening through holes in the top wall of the roadway, and then connecting and pushing the exhaust pipes one by one into the through holes to remove the combustible gas from the roadway. However, as the number of pipes increases, it will inevitably bring greater pressure to the workers at the bottom, increase their labor intensity, and there is a risk that the pipes may fall and injure the workers at the bottom. This greatly affects the installation efficiency of the pipes in the combustible gas removal operation. Summary of the Invention

This not only reduces labor intensity but also effectively improves the efficiency of sleeve installation, solving the problems in the prior art.

[0004] The technical solution adopted by this invention to solve its technical problem is as follows: A portable sleeve installation machine of this invention includes a vertically arranged column, a lower bottom tube fitted at the bottom of the column, and an upper top tube fitted at the top of the column. The lower bottom tube and the upper top tube can move vertically relative to the column. A height adjustment device is installed at the bottom of the lower bottom tube. A sleeve clamping and lifting mechanism is installed on the column. The sleeve clamping and lifting mechanism includes a connecting frame mounted on the column. Two sets of clamping assemblies are symmetrically arranged at both ends of the connecting frame. Each clamping assembly includes a mounting seat mounted on the connecting frame. The mounting seat is provided with two first... The system comprises a rotating shaft, with a swing frame mounted on each first rotating shaft. The swing frame can rotate around the first rotating shaft. The swing frame also has a second rotating shaft and a third rotating shaft. The second rotating shaft has a clamping groove wheel with friction protrusions on its inner circumference. A tension spring is installed between the third rotating shafts on the same side of the two clamping assemblies. The tension spring always tends to bring the two clamping groove wheels on each clamping assembly closer together. A pneumatic motor is mounted on the connecting frame. The output shaft of the pneumatic motor is connected to the two second rotating shafts of one of the clamping assemblies through a transmission device. When the pneumatic motor is started, it can drive the two clamping groove wheels to rotate synchronously in opposite directions. The upper jacking tube is equipped with a positioning pin, and the column has a guide groove arranged along its length. A first fastening bolt is installed on the lower jacking tube, and a lower fastening pad that mates with the guide groove is installed on the stud of the first fastening bolt extending into the lower jacking tube. A second fastening bolt is installed on the upper jacking tube, and an upper fastening pad that mates with the guide groove is installed on the stud of the second fastening bolt extending into the upper jacking tube. The lower jacking tube and the upper jacking tube can move vertically relative to the column. A fixing clamp support is installed on the column, and the fixing clamp support is connected to the connecting frame via a fixing clamp. A third fastening bolt is installed on the fixing clamp support, and a middle fastening pad that mates with the guide groove is installed on the stud of the third fastening bolt extending into the fixing clamp support. The fixing clamp support can move vertically relative to the column. The height adjustment device includes a mounting box located at the bottom of the lower tube. A nut sleeve is installed inside the mounting box, and a nut is located inside the nut sleeve. The lower end of the nut extends out of the nut sleeve and is fitted with a handwheel.

Meshing transmission gears are mounted on two first rotating shafts, allowing them to rotate synchronously in opposite directions. A first sprocket is also mounted on the first rotating shaft, and a second sprocket is mounted on the second rotating shaft. A transmission chain is fitted between the first and second sprockets. When the pneumatic motor starts, it sequentially drives two clamping grooved wheels to rotate synchronously in opposite directions via the worm gear reducer, the first sprocket, the transmission chain, and the second sprocket.A manual wheel separation device is installed between the two clamping assemblies. This device includes a fourth rotating shaft mounted on a swing frame.

[0018] The portable sleeve installation machine described in this invention, such as Figure 1 , Figure 2 and Figure 3 As shown, the installation includes a vertically installed column 1. A height adjustment device is installed at the bottom of the column 1. The height adjustment device can adjust the height of the entire installation machine according to the height position of the through hole in the roadway to achieve support in the roadway. A casing clamping and lifting mechanism is installed on the column 1. The casing clamping and lifting mechanism can clamp and feed the casing to complete the upward installation of the casing.

[0019] The sleeve clamping and lifting mechanism includes a connecting frame 2 mounted on a column 1. Two sets of clamping assemblies are symmetrically arranged at both ends of the connecting frame 2. Each clamping assembly includes a mounting base 3 mounted on the connecting frame 2. The mounting base 3 has two first rotating shafts 4, each with a swing frame 5 mounted on it. The swing frame 5 can rotate around the first rotating shaft 4. A second rotating shaft 6 and a third rotating shaft 7 are also mounted on the swing frame 5. The second rotating shaft 6 has clamping grooved wheels 8 mounted on it, which clamp the sleeve. A tension spring 9 is installed between the third rotating shafts 7 on the same side of the two clamping assemblies. The tension spring 9 always tends to bring the two clamping grooved wheels 8 on each clamping assembly closer together. A pneumatic motor 10 is installed on the connecting frame 2. The output shaft of the pneumatic motor 10 is connected to two second rotating shafts 6 of one of the clamping assemblies through a transmission device. As a power device, the pneumatic motor 10 can drive the two clamping groove wheels 8 to rotate synchronously in opposite directions when started, thereby realizing the vertical movement of the clamping sleeve.

[0020] like Figure 2 As shown, the two clamping assemblies are arranged symmetrically. The clamping groove wheel 8 of the upper clamping assembly is located at the lower part of the corresponding mounting base 3, and the clamping groove wheel 8 of the lower clamping assembly is located at the upper part of the corresponding mounting base 3. A tension spring 9 is installed between the third rotating shafts 7 on the same side. Under the tension of the tension spring 9, the two third rotating shafts 7 tend to move closer together. The upper and lower clamping assemblies rotate around their respective first rotating shafts 4, causing the two clamping groove wheels 8 to move closer together and clamp the sleeve. The clamping grooved wheels 8 of the two clamping assemblies clamp the sleeve, which can effectively prevent the sleeve from shifting during the upward installation process. The clamping grooved wheel 8 of the lower clamping assembly can move the sleeve upward and feed it in through friction under the drive of the pneumatic motor 10. The clamping force between the two clamping grooved wheels 8 in the same clamping assembly is provided by the tension spring 9. The distance between the clamping grooved wheels 8 has a certain degree of floating. Without damaging the sleeve, it can also adapt to the clamping and feeding of the sleeve at the position of changing diameter.

[0021] To allow for significant pre-adjustment of the overall machine height based on through holes at different heights, a lower bottom tube 11 is fitted to the bottom of the column 1, and an upper top tube 12 is fitted to the top of the column 1. A positioning pin 13 is installed on the upper top tube 12, which can penetrate into the tunnel ceiling wall to ensure stable installation of the entire machine. The column 1 is provided with guide grooves 14 arranged along its length, such as... Figure 4 and Figure 5As shown, a first fastening bolt 15 is installed on the lower bottom tube 11. A lower fastening pad 16, which mates with the guide groove 14, is installed on the stud of the first fastening bolt 15 extending into the lower bottom tube 11. A second fastening bolt 17 is installed on the upper top tube 12. An upper fastening pad 18, which mates with the guide groove 14, is installed on the stud of the second fastening bolt 17 extending into the upper top tube 12. When the first fastening bolt 15 and the second fastening bolt 17 are loosened, the lower bottom tube 11 and the upper top tube 12 can move vertically relative to the column 1 under the guidance of the lower fastening pad 16 and the upper fastening pad 18, respectively, to achieve the function of adjusting the overall length. When the first fastening bolt 15 and the second fastening bolt 17 are tightened, the lower bottom tube 11 and the upper top tube 12 are relatively fixed on the column 1.

[0022] To facilitate the assembly and disassembly of the column 1 and the connecting frame 2, and to adjust the height of the clamping assembly on the connecting frame 2 on the column 1, such as Figure 3 As shown, a fixing clamp support 19 is installed on the column 1, and the fixing clamp support 19 is connected to the connecting frame 2 via a fixing clamp 20, as shown. Figure 6 As shown, a third fastening bolt 21 is installed on the fixed clamp support 19. The third fastening bolt 21 extends into the stud of the fixed clamp support 19 and a middle fastening pad 22 that mates with the guide groove 14 is installed. When the third fastening bolt 21 is loosened, the fixed clamp support 19 can move vertically relative to the column 1 under the guidance of the middle fastening pad 22, adjusting the height position of the clamping assembly on the column 1 as needed. When the third fastening bolt 21 is tightened, the fixed clamp support 19 is fixed relative to the column 1.

[0023] After the column 1 is installed in place, in order to ensure that the portable casing installation machine is stably supported between the top and bottom walls of the tunnel and to achieve adaptive installation at different through-hole positions, the height adjustment device is set at the bottom of the lower pipe 11, such as... Figure 7 As shown, the height adjustment device includes a mounting box 23 located at the bottom of the lower tube 11. A threaded nut sleeve 24 is installed inside the mounting box 23, which can be welded and fixed to the bottom of the lower tube 11. A threaded nut 25 is provided inside the threaded nut sleeve 24. The lower end of the threaded nut 25 extends out of the threaded nut sleeve 24 and is fitted with a handwheel 26. The upper end of the threaded nut 25 extends out of the threaded nut sleeve 24 and is fitted with a limit ring 27, allowing the threaded nut 25 to be vertically positioned relative to the threaded nut sleeve 24. A lead screw 28 is fitted inside the threaded nut 25. The upper end of the lead screw 28 is located inside the lower tube 11, and the lower end of the lead screw 28 is fitted with a center point 29. When the handwheel 26 is turned, the threaded nut 25 rotates synchronously. Because the threaded nut 25 is vertically fixed, the lead screw 28 fitted inside the threaded nut 25 moves vertically, thereby adjusting the overall height of the mounting machine. The tip 29 at the lower end of the lead screw 28 can be inserted into the tunnel wall or the laid sleepers to further ensure the stable installation of the installation machine.

[0024] When using the portable casing installation machine, first install the column 1 in the designated position, and turn the handwheel 26 to adjust the length of the entire device as needed, so that the upper and lower ends of the column 1 are pressed against the top and bottom walls of the roadway. Then, place the casings to be installed one by one between the clamping groove wheels 8. The pneumatic motor 10 starts and drives the two clamping groove wheels 8 to rotate synchronously in opposite directions, causing the casings to move vertically in sequence. The casing installation is completed by the casing clamping and lifting mechanism. During the installation process, the biggest safety issue is that when the pipe hole in the top wall is blocked, high-pressure methane gas is trapped inside. In the traditional manual casing installation, when the casing is installed upwards to clear the blockage, the methane gas will explode and directly blast the casing out, injuring the operator at the bottom. However, with the portable casing installation machine, when encountering pipe hole blockage, remote operation can be performed. The falling casing will first impact the equipment, effectively avoiding injuries and other dangers during the installation process.

[0025] The transmission device can be an existing gear transmission mechanism or belt transmission mechanism. In order to ensure transmission accuracy while achieving synchronous transmission of the clamping grooved pulleys 7 on both sides, such as... Figure 8 and Figure 9 As shown, the transmission device includes a worm gear reducer 30 connected to the output shaft of the pneumatic motor 10. The output shaft of the worm gear reducer 30 is connected to a first rotating shaft 4. Two meshing transmission gears 31 are mounted on the two first rotating shafts 4, and the transmission gears 31 can rotate synchronously in opposite directions. A first sprocket 32 ​​is also mounted on the first rotating shaft 4, and a second sprocket 33 is mounted on the second rotating shaft 6. A transmission chain 34 is fitted between the first sprocket 32 ​​and the second sprocket 33. When the pneumatic motor 10 starts, it can sequentially drive the two clamping groove wheels 8 to rotate synchronously in opposite directions through the worm gear reducer 30, the first sprocket 32, the transmission chain 34, and the second sprocket 33. The transmission gear 31 can be located on the rear side of the mounting base 3, and the first sprocket 32 ​​can be located on the front side of the mounting base 3. When the pneumatic motor 10 drives the transmission gear 31, the first sprocket 32 ​​on the first rotating shaft 4, and the second sprocket 33 on the second rotating shaft 6 to rotate, it will not affect the normal rotation of the swing frame 5.

[0026] The worm gear reducer 30, while providing normal transmission and speed reduction, also has a self-locking function to prevent the falling sleeve from causing the transmission device to reverse without power, thus effectively protecting the transmission device in the sleeve clamping and lifting mechanism. The transmission gear 31 ensures that the clamping groove wheels 8 on both sides of the same clamping assembly can rotate synchronously in opposite directions, thereby achieving normal sleeve feeding.

[0027] Furthermore, to facilitate the separation and removal of the portable sleeve installation machine from the sleeve after installation, a manual grooved wheel separation device is installed between the two clamping assemblies, such as... Figure 10As shown, the manual grooved wheel separation device includes a fourth rotating shaft 35 mounted on the swing frame 5. A first synchronous connecting rod 36 is hingedly mounted on one of the fourth rotating shafts 35 in the same clamping assembly, and a second synchronous connecting rod 37 is hingedly mounted on the other fourth rotating shaft 35. The first synchronous connecting rod 36 and the second synchronous connecting rod 37 are connected by a guide shaft 38, and both the first synchronous connecting rod 36 and the second synchronous connecting rod 37 can rotate relative to the guide shaft 38. The connecting frame 2 has a guide groove 39 that mates with the guide shaft 38, such as... Figure 11 As shown, the guide groove 39 is vertically arranged within the connecting frame 2. Limiting rods 40 are installed at both the upper and lower ends of the guide groove 39, allowing the guide shaft 38 to move vertically between the two limiting rods 40 within the guide groove 39. Under the connection of the first synchronous link 36 and the second synchronous link 37, and with the guide shaft 38 moving to a specific position, the two swing frames 5 of the same clamping assembly can rotate synchronously in opposite directions, allowing a tension spring 9 to be installed within the sleeve clamping and lifting mechanism.

[0028] A connecting plate 41 is provided on the first synchronous connecting rod 36, and a third synchronous connecting rod 42 is hingedly mounted on the connecting plate 41. The third synchronous connecting rods 42 of the two sets of clamping assemblies are connected through a fifth rotating shaft 43, and the third synchronous connecting rod 42 can rotate relative to the fifth rotating shaft 43. A handle 44 is hingedly mounted on the connecting frame 2, and a linkage rod 45 is provided on the handle 44. One end of the linkage rod 45 is hinged to the handle 44, and the other end of the linkage rod 45 is hinged to the fifth rotating shaft 43. When the handle 44 is rotated so that the two guide shafts 38 move away from each other, it can drive the two clamping groove wheels 8 on each set of clamping assemblies to separate. Figure 11 As shown, a bearing can be installed at the end of the guide shaft 38 to provide a corresponding guiding function.

[0029] The clamping groove wheels 8 are close together, clamping the sleeve as follows: Figure 10 As shown, under the action of the tension spring 9, the two clamping groove wheels 8 on the same clamping assembly move closer to each other to clamp the sleeve. When it is necessary to rotate and separate the two clamping groove wheels 8, the required operation is as follows: Figure 10 Rotating the handle 44 counterclockwise in the direction shown causes the linkage 45 to move together. The linkage 45 drives the fifth rotating shaft 43 to gradually approach the guide groove 39. At the same time, the two third synchronous linkages 42 drive the connecting plates 41 at their respective ends to move away from each other. The two guide shafts 38 also move away from each other in the guide groove 39. That is, the guide shaft 38 in the upper clamping assembly moves upward and the guide shaft 38 in the lower clamping assembly moves downward.

[0030] The relative movement of each component within the two clamping assemblies is the same, but their overall direction is opposite due to their symmetrical arrangement on the connecting frame 2. Taking the lower clamping assembly as an example, the downward-moving guide shaft 38 increases the angle between the first synchronous link 36 and the second synchronous link 37, thereby causing the two swing arms 5 to rotate in opposite directions against the tension of the tension spring 9 and separate. The two clamping groove wheels 8 also separate from each other until... Figure 12 As shown in the diagram, the two third synchronous links 42 rotate to the same straight line position, and the two connecting plates 41 move to a position parallel to the third synchronous links 42, thus forming a self-locking mechanism.

[0031] The force applied to the swing frame 5 by the tension spring 9 tends to decrease the angle between the first synchronous link 36 and the second synchronous link 37, which requires the two guide shafts 38 to move closer together. However, the connecting plates 41 of the two clamping assemblies are in the same straight line position, and the third synchronous link 42 of the two clamping assemblies is also in the same straight line position. This causes the forces on the third synchronous link 42 to cancel each other out, preventing relative rotation, and thus the device is maintained at a constant position. Figure 12 The state shown is as follows. With the clamping wheel 8 no longer clamping the sleeve, the operator can remove the portable sleeve installer from the side of the vertically arranged sleeves, completing the separation and removal of the portable sleeve installer. When the operator turns the handle lever 44 clockwise, causing the two third synchronous connecting rods 42 to de-align, the clamping assembly returns to its original position under the tension of the tension spring 9. Figure 10 As shown, the clamping groove wheel 8 in the casing clamping and lifting mechanism can achieve normal clamping of the casing.

[0032] Furthermore, in order to effectively reduce the weight of the synchronizing link while ensuring normal transmission, both the first synchronizing link 36 and the second synchronizing link 37 are provided with elongated holes 46.

[0033] Furthermore, to ensure the normal operation of the casing clamping and lifting mechanism in complex and harsh environments such as underground roadways, a protective cover 47 is installed on the connecting frame 2, and the casing clamping and lifting mechanism is located inside the protective cover 47. To ensure the normal operation of the manual grooved wheel separation device inside the protective cover 47, a clearance groove 48 that cooperates with the handle 44 is also provided on one side of the protective cover 47.

[0034] Furthermore, to increase the friction between the clamping groove wheel 8 and the sleeve, friction protrusions are provided on the inner circumferential surface of the clamping groove wheel 8 to ensure that the sleeve moves upward and is installed when the clamping groove wheel 8 rotates.
