Description

Technical Field

[0001] This invention belongs to the field of pile-forming machine technology, specifically an eleven-axis mixing pile-forming machine. Background Technology

[0002] A pile driver is a machine that uses rotation or impact to create holes and then forms piles in those holes. Pile drivers are also called pile-driving machines. Common pile drivers include single-axis, three-axis, and five-axis models. They are mainly used in dike projects and reservoir dams (in water conservancy seepage prevention curtains and foundation reinforcement projects).

[0003] However, the aforementioned technologies often have the following drawbacks: Anti-seepage wall projects are mostly used in dike and reservoir dam projects where the construction site is long and narrow, the construction period is tight, and environmental protection and quality requirements are high. The anti-seepage construction of dikes and reservoir dams is affected by the flood season, often resulting in tight schedules, high environmental requirements, and limited access roads to and from the dike (dam) crest. Conventional three-axis and five-axis cement mixing equipment suffers from low construction efficiency, high cement consumption, and limited access for construction elements to and from the site. Therefore, this invention provides an eleven-axis mixing pile driver. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: The eleven-axis mixing pile machine of this invention includes a machine body, a connector, and a set of shafts. One part of the shafts is a grouting pipe, and the other part is an air jet pipe. The connector is set on the machine body, and a set of connectors is fixedly connected to the bottom surface of the connector. The shafts correspond one-to-one with the connectors, and the shafts are installed inside the connectors. Mixing blades are fixedly connected to the surface of the shafts. A drive mechanism for driving the shafts to rotate is provided inside the connector. There are eleven connectors in the set. The shafts are then installed on the connectors. Each shaft has 6 grouting pipes and 5 air jet pipes (the air pipes are 28-32 cm higher than the grouting pipes). When the shafts rotate under the drive mechanism, the shafts of the air jet pipes are sprayed onto the mixing blades during the airflow turbulence, increasing workability and thus forming a grout-soil integrated structure. Each shaft has multiple rows of mixing blades, a high-power hydraulic winch, and uniform drilling and lifting speeds. The drilling is clockwise. The needle-type mixing system, with its counter-clockwise stirring, improves mud utilization. After the shaft rotates 100 revolutions, the high-speed drill bit injects mud, breaking up the soil to form mud. After overflowing from the trench, the mud is collected and returned to the backstage, where it is mixed with cement. After passing inspection, it is recycled and reused. The drilling and lifting speed and grouting flow rate can be adjusted and fixed according to design requirements, resulting in more thorough soil cutting and more uniform grout distribution, leading to higher cement-soil strength, better overall uniformity, and better water-stopping effect. The daily completed anti-seepage wall area can reach 3.3 times that of a three-axis cement mixing pile machine. With the increase in the number of shafts, drilling is more stable and verticality is better. The system adopts permanent magnet variable frequency overclocking technology, which automatically adjusts the speed according to different strata. It can select different speeds for different soil conditions to meet the requirements of high torque during drilling and high speed during lifting, resulting in higher quality and more controllable pile formation. It also reduces the number of equipment operating simultaneously, ensuring easier access for construction elements such as cement and diesel to and from the construction site, and minimizing the impact of construction on local production and life.

[0006] Preferably, a pair of connecting plates are fixedly connected to the bottom surface of the connector, a lead screw is rotatably connected inside the connecting plates, a fixed plate is threaded onto the surface of the lead screw, the top surface of the fixed plate is slidably connected to the bottom surface of the connector, a motor for driving the lead screw to rotate is provided on one side of the connector, a moving block is slidably connected to the bottom surface of the fixed plate, slide rods are slidably connected to both sides of the moving block, an arc-shaped positioning block is fixedly connected to the other end of the slide rod, a ball is movably connected to the inner wall of the positioning block, and a moving mechanism is provided on the moving block to drive itself and the slide rods to move; since the shaft needs to be assembled into the connector during use, it is inconvenient for the operator to align the shaft with the connector. In this case, the above mechanism is used to start the motor, causing the motor to drive... The lead screw rotates, driving the fixed plate to move to the connector. The shaft is then placed at the connector. Next, the sliding rod is moved by the moving mechanism, causing the positioning block to clamp the shaft. At this point, the ball contacts the shaft, and the shaft aligns with the connector under the action of the positioning block. The shaft is then installed into the connector, improving the ease of installation. As the shaft moves on the positioning block, the ball rotates, reducing resistance during shaft movement. After installation, the moving mechanism removes the positioning block from the shaft and moves it away from the shaft. The fixed plate is then moved again, allowing the positioning block to move to the next connector to continue installing the shaft.

[0007] Preferably, the moving mechanism includes a first electromagnet fixed to the surface of the slide bar, the first electromagnet being magnetically attracted to a moving block made of magnetic material, a first spring being fixedly connected between the first electromagnet and the moving block, and a second electromagnet magnetically attracted to the moving block being fixedly connected to the bottom surface of the fixed plate, the second electromagnet being fixedly connected to the moving block by a second spring. When the positioning block needs to clamp and position the shaft, the first electromagnet is activated to magnetically attract the moving block, at which point the slide bar will move along with the first electromagnet, and then the slide bar will drive the positioning block to clamp the shaft. After the shaft is installed, the first electromagnet is turned off, at which point the first spring will push the electromagnet, thereby causing the positioning block to no longer clamp the shaft. Then the second electromagnet is activated, causing the second electromagnet to magnetically attract the moving block, at which point the moving block will move to the side closer to the second electromagnet, thereby allowing the positioning block to be completely removed from the shaft. With the help of the above mechanism, the positioning block can be moved automatically, eliminating the need for manual movement and improving the practicality of the positioning block in use.

[0008] Preferably, a groove is formed on one side of the fixing plate, and a first magnetic block is slidably connected to the inner wall of the groove. A rectangular plate is fixedly connected to the side of the fixing plate near the first magnetic block, and a third spring is fixedly connected between the rectangular plate and the first magnetic block. A set of positioning plates repelling the first magnetic block is slidably connected to the bottom surface of the connector. The positioning plates are made of magnetic material. A second magnetic block repelling the positioning plates is fixedly connected to the side of the fixing plate away from the first magnetic block. A connecting wire is fixedly connected between the first magnetic block and the slide rod. When the lead screw moves the fixing plate, the fixing plate will move to contact the positioning plates, thereby causing the fixing plate to move the positioning block to the connector head, thus achieving the positioning function of the positioning block. At this time, the first magnetic block will be below the positioning plate. There is a distance between the first magnetic block and the positioning plate. At this point, the distance is insufficient for the first magnetic block and the positioning plate to repel each other. Then, when the slide rod drives the positioning block to clamp the shaft, the connecting wire will loosen. At this time, the first magnetic block will move upward under the push of the third spring. The first magnetic block will push the positioning plate into the connector, so that the positioning plate no longer contacts the side of the fixing plate. At this time, the positioning plate will not hinder the movement of the fixing plate. When the fixing plate needs to be reset, the lead screw can be reversed. Then, during the movement of the fixing plate, the second magnetic block will repel the positioning plate, allowing the positioning plate to enter the connector. Through the above mechanism, when the lead screw drives the fixing plate to move, the fixing plate can be positioned at the connector head, thereby further improving the speed of shaft installation.

[0009] Preferably, an arc-shaped elastic block is fixedly connected to the top surface of the positioning block. The elastic block has a hollow internal structure, and an inflation mechanism for inflating the elastic block is provided inside the positioning block. Because the shaft may accumulate impurities at the connection point with the connector due to the complex environment of the construction site, these impurities can affect the connection between the shaft and the connector. In this case, when the positioning block clamps the shaft, the inflation mechanism can inflate the elastic block. When the shaft passes over the elastic block, the inner wall of the elastic block can scrape away the impurities on the shaft. Then, the cleaned shaft can be connected to the connector, thereby improving the connection effect between the shaft and the connector.

[0010] Preferably, the inflation mechanism includes a magnetic sheet, the positioning block has a hollow interior, the magnetic sheet is slidably connected to the inner wall of the positioning block, and a set of fourth springs is fixedly connected between the side of the magnetic sheet away from the sphere and the inner wall of the positioning block. When the positioning blocks move close to each other, the magnetic sheets inside them will repel each other. A connecting hole is provided between the positioning block and the elastic block. When the positioning blocks move close to each other to clamp the shaft, the magnetic sheets inside the positioning blocks will repel each other. At this time, the magnetic sheets will push the gas inside the positioning blocks, causing the gas to enter the elastic block from the connecting hole and expand. Through the above mechanism, the elastic block can be expanded during the movement of the positioning blocks.

[0011] Preferably, the positioning block stores water on the side of the magnetic sheet closest to the sphere, and the surface of the sphere has a groove. When the shaft moves at the positioning block, the sphere rotates, and the groove on the sphere digs the water stored in the positioning block onto the shaft, making the surface of the shaft wet. When the shaft passes the elastic block, the elastic block can better clean the impurities on the shaft, thereby improving the cleaning effect on the shaft.

[0012] Preferably, an elastic and hollow expansion block is fixedly connected to the inner wall of the positioning block where water is stored. As the water level in the positioning block decreases during continuous use, the groove of the sphere will not be able to dig out the water. When the water level decreases, the expansion block will expand and push the water in the positioning block, so that the water is always full in the positioning block. At this time, the water can be better dug out by the groove, thereby improving the water utilization efficiency.

[0013] Preferably, the sphere has a hollow interior, and a guide plate that is magnetically attracted to the magnetic sheet is fixedly connected to the inner wall of the sphere. After the shaft is positioned, when the sphere stops rotating, the groove may be partially located on the positioning block and partially outside the positioning block. In this case, water will continuously leak from the groove. After the shaft is positioned, the first electromagnet can be turned off immediately to prevent the positioning block from clamping the shaft. The sphere can then rotate freely. The guide plate will be magnetically attracted to the magnetic sheet, causing the sphere to rotate and preventing water from continuously leaking from the positioning block from the groove.

[0014] Preferably, the inner wall of the positioning block is fixedly connected to a third electromagnet that repels the magnetic sheet; after the expansion block scrapes away the surface impurities at the point where the shaft needs to be connected to the connector, the third electromagnet can be activated to repel the magnetic sheet. At this time, the positioning block will draw in the gas in the elastic block from the connection hole, causing the elastic block to deflate and no longer contact the shaft, thereby reducing the resistance of the shaft when it moves.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. With the increase in the number of shafts, drilling becomes more stable and the verticality is better. The use of permanent magnet variable frequency overclocking technology automatically adjusts the rotation speed according to different strata. Different rotation speeds can be selected for different soil conditions to meet the requirements of high torque during drilling and high rotation speed during drilling. The pile formation is more high-quality and controllable, the number of equipment operating at the same time is reduced, and the access of construction elements such as cement and diesel to and from the construction site is more convenient, minimizing the impact of the construction process on local production and life.

[0017] 2. Since the shaft needs to be assembled into the connector during use, it is inconvenient for workers to align the shaft with the connector during installation. The aforementioned mechanism starts the motor, causing the motor to drive the lead screw to rotate. The lead screw then drives the fixing plate to move to the connector, where the shaft is placed. Next, the moving mechanism drives the sliding rod to move, allowing the positioning block to clamp the shaft. At this point, the ball contacts the shaft, and the shaft aligns with the connector under the action of the positioning block. The shaft is then installed into the connector, improving the ease of installation. As the shaft moves on the positioning block, the ball rotates, reducing resistance during movement. After installation, the moving mechanism removes the positioning block from the shaft and moves it away from the shaft. Then, the fixing plate is moved again, allowing the positioning block to move to the next connector for shaft installation. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] Example 1:

[0029] like Figures 1 to 6 As shown in the figure, the eleven-axis mixing pile machine of the present invention includes a machine body 31, a connector 1, and a set of shafts 3. Part of the shafts 3 are grouting pipes, and the other part of the shafts 3 are air jet pipes. The connector 1 is set on the machine body 31. A set of connectors 2 are fixedly connected to the bottom surface of the connector 1. The shafts 3 correspond one-to-one with the connectors 2, and the shafts 3 are installed inside the connectors 2. Mixing blades 4 are fixedly connected to the surface of the shafts 3. A drive mechanism for driving the shafts 3 to rotate is provided inside the connector 1.

[0030] A set of connectors 2 consists of eleven parts. The shaft 3 is then installed onto the connectors 2. The shaft 3 has six grouting pipes and five air jet pipes (the air pipes are 28-32 cm higher than the grouting pipes). When the shaft 3 rotates under the drive mechanism, the air jet pipes on the shaft 3 spray onto the mixing blades 4 during the airflow turbulence, increasing workability and forming a unified grout-soil mixture. Each shaft has multiple rows of mixing blades 4. A high-power hydraulic winch ensures uniform drilling and lifting speeds. Drilling is clockwise during descent and counter-clockwise during lifting, improving mud utilization. After the shaft 3 reaches 100 revolutions, a high-speed drill bit injects mud, breaking up the soil to form mud. After overflowing the trench, the mud is collected and returned to the backstage area, mixed with cement, and recycled after passing inspection. The drilling and lifting speeds are adjusted accordingly. The drilling speed and grouting flow rate can be adjusted and fixed according to design requirements, resulting in more thorough soil cutting and more uniform grouting, leading to higher cement-soil strength, better overall uniformity, and better water-stopping effect. The daily completed anti-seepage wall area can reach 3.3 times that of a three-axis cement mixing pile machine. With the increase in the number of axes, drilling is more stable and the verticality is better. The permanent magnet variable frequency overclocking technology is adopted to automatically adjust the speed according to different strata. Different speeds can be selected for different soil conditions to meet the requirements of high torque during drilling and high speed during drilling. The pile formation is more high-quality and controllable, reducing the number of equipment operating at the same time and ensuring that construction elements such as cement and diesel can enter and exit the construction site more conveniently, minimizing the impact of the construction process on local production and life.

[0031] A pair of connecting plates 5 are fixedly connected to the bottom surface of the connector 1. A lead screw 6 is rotatably connected inside the connecting plates 5. A fixing plate 7 is threadedly connected to the surface of the lead screw 6. The top surface of the fixing plate 7 is slidably connected to the bottom surface of the connector 1. A motor 30 is provided on one side of the connector 1 to drive the lead screw 6 to rotate. A moving block 8 is slidably connected to the bottom surface of the fixing plate 7. A slide rod 9 is slidably connected to both sides of the moving block 8. An arc-shaped positioning block 10 is fixedly connected to the other end of the slide rod 9. A ball 22 is movably connected to the inner wall of the positioning block 10. A moving mechanism is provided on the moving block 8 to drive itself and the slide rod 9 to move.

[0032] Since the shaft 3 needs to be assembled into the connector 2 during use, it is inconvenient for the operator to align the shaft 3 with the connector 2. At this point, the aforementioned mechanism starts the motor 30, causing the lead screw 6 to rotate. The lead screw 6 then drives the fixing plate 7 to move to the connector 2, where the shaft 3 is placed. Next, the moving mechanism drives the slide bar 9 to move, allowing the positioning block 10 to clamp the shaft 3. At this point, the ball 22 contacts the shaft 3, and the shaft 3, under the action of the positioning block 10, engages with the connector. Align the shaft 3 with the connector 2, and then install the shaft 3 into the connector 2. This improves the ease of installing the shaft 3 into the connector 2. When the shaft 3 moves on the positioning block 10, the ball 22 will rotate, thereby reducing the resistance when the shaft 3 moves. After installation, the positioning block 10 will no longer hold the shaft 3 with the help of the moving mechanism. At the same time, the moving block 8 will be driven to move, so that the positioning block 10 moves from the shaft 3. Then the fixing plate 7 will be moved again, so that the positioning block 10 moves to the next connector 2 to continue installing the shaft 3.

[0033] The moving mechanism includes a first electromagnet 11 fixed on the surface of the slide bar 9, the first electromagnet 11 being magnetically attracted to the moving block 8 made of magnetic material, a first spring 12 being fixedly connected between the first electromagnet 11 and the moving block 8, a second electromagnet 13 being magnetically attracted to the moving block 8 being fixedly connected to the bottom surface of the fixed plate 7, and a second spring 14 being fixedly connected between the second electromagnet 13 and the moving block 8.

[0034] When the positioning block 10 needs to clamp and position the shaft 3, the first electromagnet 11 is activated and magnetically attracted to the moving block 8. At this time, the slide bar 9 will move with the first electromagnet 11, and then the slide bar 9 will drive the positioning block 10 to clamp the shaft 3. After the shaft 3 is installed, the first electromagnet 11 is turned off. At this time, the first spring 12 will push the electromagnet, so that the positioning block 10 will no longer clamp the shaft 3. Then the second electromagnet 13 is activated, so that the second electromagnet 13 is magnetically attracted to the moving block 8. At this time, the moving block 8 will move to the side closer to the second electromagnet 13, so that the positioning block 10 is completely removed from the shaft 3. With the help of the above mechanism, the positioning block 10 can be moved automatically, and it is impossible to move the positioning block 10 manually, which improves the practicality of the positioning block 10 in use.

[0035] A groove is provided on one side of the fixing plate 7. A first magnetic block 15 is slidably connected to the inner wall of the groove. A rectangular plate 17 is fixedly connected to the side of the fixing plate 7 near the first magnetic block 15. A third spring 16 is fixedly connected between the rectangular plate 17 and the first magnetic block 15. A set of positioning plates 20 that repel the first magnetic block 15 are slidably connected to the bottom surface of the connector 1. The positioning plates 20 are made of magnetic material. A second magnetic block 19 that repels the positioning plates 20 is fixedly connected to the side of the fixing plate 7 away from the first magnetic block 15. A connecting wire 18 is fixedly connected between the first magnetic block 15 and the slide rod 9.

[0036] When the lead screw 6 moves the fixed plate 7, the fixed plate 7 will move to contact the positioning piece 20, thereby causing the fixed plate 7 to move the positioning block 10 to the connector 2, thus achieving the positioning function of the positioning block 10. At this time, the first magnetic block 15 will be below the positioning piece 20, and there will be a distance between the first magnetic block 15 and the positioning piece 20. At this time, the distance between them is not enough for the first magnetic block 15 to repel the positioning piece 20. Then, when the slide rod 9 moves the positioning block 10 to clamp the shaft 3, the connecting wire 18 will be released. At this time, the first magnetic block 15 will be pushed upward by the third spring 16. When the device moves, the first magnetic block 15 pushes the positioning piece 20 into the connector 1, so that the positioning piece 20 no longer contacts the side of the fixing plate 7. At this time, the positioning piece 20 will not hinder the movement of the fixing plate 7. When the fixing plate 7 needs to be reset, the lead screw 6 can be reversed. Then, during the movement of the fixing plate 7, the second magnetic block 19 will repel the positioning piece 20, allowing the positioning piece 20 to enter the connector 1. Through the above mechanism, when the lead screw 6 drives the fixing plate 7 to move, the fixing plate 7 can be positioned at the connector 2, thereby further improving the speed of installing the shaft 3.

[0037] An arc-shaped elastic block 21 is fixedly connected to the top surface of the positioning block 10. The elastic block 21 has a hollow structure inside. An inflation mechanism for inflating the elastic block 21 is provided inside the positioning block 10. In actual use, due to the complex environment of the construction site, the connection between the shaft 3 and the connector 1 is prone to impurities. These impurities will affect the connection effect between the shaft 3 and the connector 1. At this time, when the positioning block 10 clamps the shaft 3, the inflation mechanism can inflate the elastic block 21. When the shaft 3 passes through the elastic block 21, the inner sidewall of the elastic block 21 can scrape off the impurities on the shaft 3. Then the cleaned shaft 3 can be connected to the connector 1, thereby improving the connection effect between the shaft 3 and the connector 1.

[0038] The inflation mechanism includes a magnetic sheet 24. The positioning block 10 has a hollow interior. The magnetic sheet 24 is slidably connected to the inner wall of the positioning block 10. A set of fourth springs 25 is fixedly connected between the side of the magnetic sheet 24 away from the sphere 22 and the inner wall of the positioning block 10. When the positioning blocks 10 move close to each other, the magnetic sheets 24 inside them will repel each other. A connecting hole 23 is provided between the positioning block 10 and the elastic block 21. When the positioning blocks 10 move close to each other to clamp the shaft 3, the magnetic sheets 24 inside the positioning block 10 will repel each other. At this time, the magnetic sheets 24 will push the gas inside the positioning block 10, so that the gas enters the elastic block 21 from the connecting hole 23 and expands. Through the above mechanism, the elastic block 21 can be expanded during the movement of the positioning block 10.

[0039] Water is stored in the positioning block 10 on the side of the magnetic sheet 24 near the sphere 22. The surface of the sphere 22 has a groove 28. When the shaft 3 moves at the positioning block 10, the sphere 22 will rotate. At this time, the groove 28 on the sphere 22 will dig out the water stored in the positioning block 10 onto the shaft 3, making the surface of the shaft 3 wet. When the shaft 3 passes the elastic block 21, the elastic block 21 can better clean the impurities on the shaft 3, thereby improving the cleaning effect on the shaft 3.

[0040] The positioning block 10 has an elastic and hollow expansion block 26 fixedly connected to its inner wall where water is stored. As the water level in the positioning block 10 decreases during continuous use, the groove 28 of the sphere 22 will be unable to dig out the water. When the water level decreases, the expansion block 26 will expand and push the water in the positioning block 10, so that the water is always full in the positioning block 10. At this time, the water can be better dug out by the groove 28, thereby improving the water utilization efficiency.

[0041] The sphere 22 has a hollow interior, and a guide plate 27 that is magnetically attracted to the magnetic plate 24 is fixedly connected to the inner wall of the sphere 22. After the shaft 3 is positioned, when the sphere 22 stops rotating, the position of the groove 28 may be partly located in the positioning block 10 and partly located outside the positioning block 10. At this time, water in the positioning block 10 will continuously leak out from the groove 28. After the shaft 3 is positioned, the first electromagnet 11 can be turned off immediately so that the positioning block 10 no longer clamps the shaft 3. At this time, the sphere 22 can rotate freely. The guide plate 27 will be magnetically attracted to the magnetic plate 24, causing the sphere 22 to rotate and preventing the position of the groove 28 from causing water to continuously leak out from the positioning block 10.

[0042] Example 2:

[0043] like Figure 7As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the inner wall of the positioning block 10 is fixedly connected to a third electromagnet 29 that repels the magnetic sheet 24; after the expansion block 26 scrapes off the surface impurities at the point where the shaft 3 needs to be connected to the connector 1, the third electromagnet 29 can be activated to repel the magnetic sheet 24. At this time, the positioning block 10 will draw in the gas in the elastic block 21 from the connection hole 23, causing the elastic block 21 to deflate and no longer contact the shaft 3, thereby reducing the resistance of the shaft 3 when it moves.

[0044] Working principle: A set of connectors 2 consists of eleven parts. The shaft 3 is then installed onto the connectors 2. The shaft 3 has six spray pipes and five air pipes (the air pipes are 28-32 cm higher than the slurry pipes). When the shaft 3 rotates under the drive mechanism, the air pipes spray onto the mixing blades 4 during the airflow turbulence, increasing workability and forming a unified slurry and soil mixture. Each shaft has multiple rows of mixing blades 4. A high-power hydraulic winch ensures uniform drilling and lifting speeds. Drilling is clockwise during descent and counter-clockwise during lifting, improving mud utilization. After the shaft 3 reaches 100 revolutions, a high-speed drill bit injects mud, breaking up the soil to form mud. After overflowing the trench, the mud is collected and returned to the backstage area, mixed with cement, and recycled after passing inspection. The lifting speed and grouting flow rate can be adjusted and fixed according to design requirements, resulting in more thorough soil cutting and more uniform grouting, leading to higher cement-soil strength, better overall uniformity, and better water-stopping effect. The daily completed anti-seepage wall area can reach 3.3 times that of a three-axis cement mixing pile machine. With the increase in the number of axes, drilling is more stable and the verticality is better. The permanent magnet variable frequency overclocking technology is adopted to automatically adjust the speed according to different strata. Different speeds can be selected for different soil conditions to meet the requirements of high torque during drilling and high speed during drilling. The pile formation is more high-quality and controllable, reducing the number of equipment operating at the same time and ensuring that construction elements such as cement and diesel can enter and exit the construction site more conveniently, minimizing the impact of the construction process on local production and life.

[0045] Since the shaft 3 needs to be assembled into the connector 2 during use, it is inconvenient for the operator to align the shaft 3 with the connector 2 during installation. At this point, the aforementioned mechanism starts the motor 30, causing the lead screw 6 to rotate. The lead screw 6 then drives the fixing plate 7 to move to the connector 2, where the shaft 3 is placed. Next, the moving mechanism drives the slide bar 9 to move, allowing the positioning block 10 to clamp the shaft 3. At this point, the ball 22 contacts the shaft 3, and the shaft 3 aligns with the connector 2 under the action of the positioning block 10. Then, the shaft 3 is installed into the connector 2, thus improving the convenience of installation. As the shaft 3 moves on the positioning block 10, the ball 22 rotates, reducing the resistance during movement. After installation, the moving mechanism removes the clamping of the positioning block 10 from the shaft 3, and simultaneously drives the moving block 8 to move. This mechanism moves the positioning block 10 from the shaft 3, then moves the fixing plate 7 again, allowing the positioning block 10 to move to the next connector 2 to continue installing the shaft 3. When the positioning block 10 needs to clamp and position the shaft 3, the first electromagnet 11 is activated and magnetically attracted to the moving block 8. At this time, the slide rod 9 will move with the first electromagnet 11, and then the slide rod 9 will drive the positioning block 10 to clamp the shaft 3. After the shaft 3 is installed, the first electromagnet 11 is turned off. At this time, the first spring 12 will push the electromagnet, so that the positioning block 10 will no longer clamp the shaft 3. Then, the second electromagnet 13 is activated, causing the second electromagnet 13 to magnetically attract to the moving block 8. At this time, the moving block 8 will move to the side closer to the second electromagnet 13, so that the positioning block 10 is completely removed from the shaft 3. With the help of the above mechanism, the positioning block 10 can be moved automatically, eliminating the need for manual movement and improving the practicality of the positioning block 10 in use.

[0046] When the lead screw 6 moves the fixed plate 7, the fixed plate 7 will move to contact the positioning piece 20, thereby causing the fixed plate 7 to move the positioning block 10 to the connector 2, thus achieving the positioning function of the positioning block 10. At this time, the first magnetic block 15 will be below the positioning piece 20, and there will be a distance between the first magnetic block 15 and the positioning piece 20. At this time, the distance between them is not enough for the first magnetic block 15 to repel the positioning piece 20. Then, when the slide rod 9 moves the positioning block 10 to clamp the shaft 3, the connecting wire 18 will be released. At this time, the first magnetic block 15 will be pushed upward by the third spring 16. When the fixed plate 7 moves, the first magnetic block 15 pushes the positioning piece 20 into the connector 1, so that the positioning piece 20 no longer contacts the side of the fixed plate 7. At this time, the positioning piece 20 will not hinder the movement of the fixed plate 7. When the fixed plate 7 needs to be reset, the lead screw 6 can be reversed. Then, during the movement of the fixed plate 7, the second magnetic block 19 will repel the positioning piece 20, allowing the positioning piece 20 to enter the connector 1. Through the above mechanism, when the lead screw 6 drives the fixed plate 7 to move, the fixed plate 7 can be positioned at the connector 2, thereby further improving the speed of installing the shaft 3.

[0047] Because the complex environment of the construction site can easily cause impurities to accumulate at the connection point between the shaft 3 and the connector 1 during actual use, these impurities can affect the connection effect between the shaft 3 and the connector 1. In this case, when the positioning block 10 clamps the shaft 3, the inflation mechanism can inflate the elastic block 21. When the shaft 3 passes through the elastic block 21, the inner wall of the elastic block 21 can scrape off the impurities on the shaft 3. Then, the cleaned shaft 3 can be connected to the connector 1, thereby improving the connection effect between the shaft 3 and the connector 1. When the positioning blocks 10 are close to each other to clamp the shaft 3, the magnetic sheets 24 inside the positioning blocks 10 will repel each other. At this time, the magnetic sheets 24 will push the gas inside the positioning blocks 10, causing the gas to enter the elastic block 21 from the connection hole 23 and expand. Through the above mechanism, the elastic block 21 can be expanded during the movement of the positioning blocks 10.

[0048] When the shaft 3 moves at the positioning block 10, the ball 22 rotates. At this time, the groove 28 on the ball 22 will dig out the water stored in the positioning block 10 onto the shaft 3, making the surface of the shaft 3 wet. When the shaft 3 passes the elastic block 21, the elastic block 21 can better clean the impurities on the shaft 3, thereby improving the cleaning effect of the shaft 3. As the water level in the positioning block 10 decreases with continuous use, the groove 28 of the ball 22 will no longer be able to dig out water. At this time, when the water level decreases, the expansion block 26 will expand and push the water in the positioning block 10, so that the water is always full in the positioning block 10. At this time, the water can be better dug out by the groove 28, thereby improving the water utilization efficiency.

[0049] After the shaft 3 is positioned, when the ball 22 stops rotating, the position of the groove 28 may be partly located in the positioning block 10 and partly outside the positioning block 10. At this time, water in the positioning block 10 will continuously leak out from the groove 28. After the shaft 3 is positioned, the first electromagnet 11 can be turned off immediately so that the positioning block 10 no longer clamps the shaft 3. At this time, the ball 22 can rotate freely. The guide plate 27 will be magnetically attracted to the magnetic plate 24, causing the ball 22 to rotate, so that the position of the groove 28 will not cause water to continuously leak out from the positioning block 10.
