Description

Technical Field

[0001] The present invention relates to the technical field of base drilling, and specifically to an automatic mud removal drilling machine device and method for ground foundation construction in open spaces. Background Art

[0002] Foundation drilling is a common construction process in building engineering, mainly used for pile foundation construction, geological exploration, underground pipeline laying, etc.

[0003] During the drilling process, it is usually necessary to add mud into the hole. The mud can form a thin film on the hole wall, playing a role in protecting the hole wall, preventing the hole wall from collapsing or shrinking. At the same time, the mud circulation can absorb part of the heat, playing a role in cooling the drill tool and reducing wear.

[0004] However, the mud and the soil generated by drilling will be mixed with each other, resulting in an increase in the viscosity of the mud. The mud may adhere to the drill pipe during the cleaning process. The soil adhering to the spiral blade shaft (drill pipe) will increase the friction between the drill pipe and the soil mass, making the drilling machine require greater power to overcome the resistance during the drilling process, resulting in a reduction in construction efficiency. Moreover, during the rotation and lifting of the drill pipe and the drill bit, due to the adhesion of the mud, the stress it receives will also increase accordingly, which will accelerate the wear of the drill pipe and the drill bit, affecting the drilling efficiency and quality, and even may cause damage to the drill pipe and the drill bit. In the prior art, in order to overcome the above defects, the drill pipe is usually taken out for cleaning, but this technical means makes the drill pipe need to be taken out for corresponding cleaning at intervals, thus resulting in a reduction in work efficiency.

[0015] An automatic mud removal drilling machine method for vacant land foundation construction comprises the following steps:

[0016] Step 1: Control the movable plate to move towards the ground direction through the lifting mechanism, and drill the foundation through the drilling component;

[0017] Step 2: Under the action of the drilling component, control the spiral blade to rotate to transport the mud generated by drilling and the like to the outside of the hole;

[0022] By controlling the differential rotation of the spiral cleaning piece and the spiral blade, the precise control of the two cleaning plates can be realized, so that they alternately move back and forth towards both sides of the spiral blade. During this process, the cleaning plate can effectively scrape the mud adhered to the spiral blade. Prevent the problems of reduced mud conveying amount and increased mud conveying difficulty of the spiral blade caused by excessive adhesion of mud on the spiral blade. Description of the Drawings

Detailed implementation method

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] In addition, the elements in the present invention are referred to as "fixed to" or "disposed on" another element, and it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0036] Please refer to Figures 1 to 10 , in the embodiment of the present invention, an automatic mud removal drilling machine device for ground foundation construction in the air and on the ground includes: a machine table 1, and a lifting plate 2 fixed on the machine table 1, and a fixing plate 4 is fixed on the lifting plate 2; it further includes: a lifting mechanism disposed on the fixing plate 4, a movable plate 10 is connected to the lifting mechanism, a drilling assembly is disposed on the movable plate 10, and a spiral blade 14 is connected to the drilling assembly; a mud cleaning mechanism is disposed on the drilling assembly, a spiral cleaning blade 22 is connected to the mud cleaning mechanism, a blade cleaning mechanism is disposed on the spiral cleaning blade 22, and the mud cleaning mechanism can drive the spiral cleaning blade 22 to rotate at a differential speed when the spiral blade 14 rotates, and perform a cleaning action on the spiral blade 14 through the blade cleaning mechanism.

[0037] Specifically, a support column 3 fixedly connected to the lifting plate 2 is fixed on the machine platform 1. Under the action of the support column 3, the supporting force for the lifting plate 2 is increased. When drilling the foundation, the machine platform 1 can be controlled to move to the required drilling position. At the same time, the lifting mechanism works, and drives the drilling assembly to move towards the foundation direction through the movable plate 10. Under the action of the drilling assembly, the foundation is drilled. The drilling assembly also drives the spiral blade 14 to rotate synchronously while entering the drill hole. Under the action of the spiral blade 14, the mud generated by drilling is discharged from the hole. And during the drilling process, the mud cleaning mechanism will control the spiral cleaning blade 22 and the spiral blade 14 to rotate at a differential speed to clean the mud adhering to the drilling assembly. The mud cleaning mechanism will also drive the blade cleaning mechanism to move to clean the mud adhering to the spiral blade 14. Among them, during the foundation drilling operation, the mud generated during the drilling process is easily adhered to the drilling assembly and the spiral blade 14. This situation will cause the weight of the drilling assembly to increase significantly, thereby affecting its balance. At the same time, during the rotation and lifting of the drilling assembly, due to the adhesion of the mud, the stress it receives will also increase accordingly, which will accelerate the wear of the drilling assembly, affect the drilling efficiency and quality, and may even cause damage to the drilling assembly. However, in this application, by controlling the differential rotation of the spiral cleaning blade 22 and the spiral blade 14, and driving the mud cleaning mechanism to move in coordination, it is possible to clean the mud adhering to the spiral blade 14 and the drilling assembly in a timely and effective manner. This process can not only keep the drilling assembly clean, avoid problems such as weight increase and balance reduction caused by mud adhesion, but also significantly reduce the stress received by the drilling assembly during rotation and lifting, thereby reducing wear, extending the service life of the drilling assembly, and ensuring that the drilled hole can meet the various requirements of the construction.

[0038] Please refer to Figures 1 - 5 、 Figure 7 The drilling assembly includes a second motor 11 fixedly installed on the movable plate 10. A drill rod 12 connected to the output shaft of the second motor 11 is rotatably installed on the movable plate 10. The drill rod 12 is fixedly connected to the spiral blade 14, and a drill bit 13 is fixed at the end of the drill rod 12.

[0039] Specifically, before drilling the foundation, the lifting mechanism can be used to control the movable plate 10 to move towards the foundation, thereby driving the drill pipe 12 and the drill bit 13 to move. When the drill bit 13 abuts against the foundation, at this time, the second motor 11 operates and drives the drill bit 13 to rotate through the drill pipe 12 to drill the foundation. During the drilling process, in order to ensure the stability of the hole wall, mud can be transported into the hole. The mud can form a thin film on the hole wall, playing a role in protecting the hole wall and preventing the hole wall from collapsing or shrinking. At the same time, as the mud circulates, it can also carry debris to a designated location to keep the drill hole clean. During the drilling process of the drill bit 13, a large amount of heat is also generated. The mud circulation can absorb part of the heat, playing a role in cooling the drill tool and reducing wear.

[0040] Please refer to Figures 1 - 5 、 Figure 7 、 Figure 9 、 Figure 10 The mud cleaning mechanism includes a guide post 15 fixed on the movable plate 10. A receiving plate 21 is fixed at the end of the guide post 15. A rotating sleeve 20 is rotatably installed on the receiving plate 21. One end of the rotating sleeve 20 is fixedly connected to the spiral cleaning blade 22 and sleeved on the drill pipe 12. A pushing component connected to the guide post 15 is arranged on the movable plate 10. Among them, the pushing component includes a cylinder 16 fixed on the movable plate 10. A pushing plate 17 slidably connected to the guide post 15 is fixed at the telescopic end of the cylinder 16. An activity sleeve 18 rotatably installed on the pushing plate 17 and slidably connected to the rotating sleeve 20 is provided on the pushing plate 17. The pushing component further includes a spiral groove 1201 formed on the circumferential outer wall of the drill pipe 12. A limiting block 19 slidably engaged with the spiral groove 1201 is fixed on the inner wall of the activity sleeve 18.

[0041] Among them, before installing the spiral blade 14 and the spiral cleaning blade 22, since their pitches are equal, therefore, they can be controlled to be combined with each other in a spiral screwing-in manner. After the combination is completed, they are synchronously controlled to be sleeved on the drill pipe 12, and they are staggered by a certain angle. At this time, the spiral blade 14 can be fixed on the drill pipe 12 by welding or other means. When the rotating sleeve 20 is sleeved on the drill pipe 12 and is in the required working position, the spiral cleaning blade 22 is fixedly connected to the rotating sleeve 20 by welding or other means, thereby completing the installation of the spiral blade 14 and the spiral cleaning blade 22.

[0042] It should be noted that a limiting groove 1801 is formed on the inner wall of the movable sleeve 18, and a limiting rod 2001 that is fixedly connected to the outer wall of the rotating sleeve 20 and is slidably fitted with the limiting groove 1801 is provided. The pitch of the spiral cleaning blade 22 is the same as that of the spiral blade 14. Before drilling starts, under the action of the cylinder 16, the movable sleeve 18 is controlled to be in a fixed state through the pushing plate 17, so that the limiting block 19 is located at the middle position of the spiral groove 1201. Under the action of the rotating sleeve 20, the spiral cleaning blade 22 and the spiral blade 14 are arranged in a staggered manner, and the staggering angle is half a turn; when the foundation needs to be drilled, at this time, under the action of the lifting mechanism, the drill bit 13 is controlled to move towards the foundation direction, and under the action of the second motor 11, the drill bit 13 and the spiral blade 14 are controlled to rotate through the drill rod 12. The drill bit 13 will drill the foundation. When the spiral blade 14 enters the drill hole, it can convey the soil generated by the drilling to the outside of the drill hole. At the same time, since the position of the limiting block 19 in the spiral groove 1201 will not change, therefore, under the action of the limiting block 19 and the spiral groove 1201, the movable sleeve 18 rotates synchronously with the drill rod 12, so as to drive the rotating sleeve 20 to rotate through the limiting groove 1801 and the limiting rod 2001, so as to drive the spiral cleaning blade 22 to rotate synchronously with the spiral blade 14; among them, it should be emphasized that the cylinder 16 controls the position of the pushing plate 17 to remain unchanged, so that the heights of the movable sleeve 18 and the limiting block 19 on the drill rod 12 remain unchanged, and the movable sleeve 18 can rotate freely. When the drill rod 12 rotates, the spiral groove 1201 will drive the movable sleeve 18 to rotate synchronously through the limiting block 19, and correspondingly, the position of the limiting block 19 in the spiral groove 1201 will not change.

[0043] During the drilling process, mud needs to be added to ensure the normal use of the drill bit 13. The mud will be mixed with the drilled soil, resulting in an increase in the viscosity of the mud and the soil. During the process of the spiral blade 14 transporting the mud and the soil, the soil and the mud may adhere to the drill pipe 12 and the spiral blade 14. Therefore, it is necessary to clean the mud and the soil. At this time, under the action of the cylinder 16, the control push plate 17 moves along the length direction of the guide post 15 and moves away from the movable plate 10, thereby driving the movable sleeve 18 to move. The movable sleeve 18 will also drive the limit block 19 to slide along the track of the spiral groove 1201 and increase the size of the engagement with the rotating sleeve 20. Under the action of the limit block 19 and the spiral groove 1201, the movable sleeve 18 rotates relative to the drill pipe 12 by a certain angle, so as to drive the rotating sleeve 20 to rotate relative to the drill pipe 12 by a certain angle through the limit groove 1801 and the limit rod 2001. Under the action of the rotating sleeve 20, the spiral cleaning piece 22 and the spiral blade 14 generate differential rotation. Therefore, the staggered angle between the spiral cleaning piece 22 and the spiral blade 14 changes. Under the action of the spiral cleaning piece 22, the mud adhering to the drill pipe 12 is cleaned. When the limit block 19 moves to the end of the stroke on one side of the spiral groove 1201, the staggered angle between the spiral cleaning piece 22 and the spiral blade 14 reaches the minimum, and a part of the drill pipe 12 is cleaned. At this time, the cylinder 16 controls the movable sleeve 18 to reset and move towards the movable plate 10 until the limit block 19 moves to the end of the stroke on the other side of the spiral groove 1201, and the staggered angle between the spiral cleaning piece 22 and the spiral blade 14 reaches the minimum again, and another part of the drill pipe 12 is cleaned.

[0044] Preferably, by controlling the reciprocating movement of the movable sleeve 18 along the length direction of the drill pipe 12, the differential rotation of the spiral cleaning piece 22 and the spiral blade 14 can be realized, and then the staggered angle between the spiral cleaning piece 22 and the spiral blade 14 can be changed. During this process, the spiral cleaning piece 22 can effectively scrape the mud adhering to the drill pipe 12. This design not only prevents the accumulation of mud on the drill pipe 12, ensures the balance of the drill pipe 12 and the drill bit 13 during rotation, but also significantly reduces the stress and wear on the drill pipe 12 during rotation and lifting, effectively extends the service life of the drill pipe 12, and reduces the maintenance cost and replacement frequency of the equipment.

[0045] In addition, during the process of cleaning the mud, since the amount of mud adhering to the drill pipe 12 is reduced, the load on the second motor 11 when driving the drill pipe 12 to rotate is correspondingly reduced, thereby ensuring the normal operation and service life of the second motor 11, and avoiding problems such as motor damage or performance degradation caused by overload.

[0046] Please refer to Figures 1 - 8The blade cleaning mechanism includes a fixed sleeve 23 fixedly mounted on the spiral cleaning piece 22, a symmetrically arranged movable rod 24 is slidably mounted in the fixed sleeve 23, a cleaning plate 26 that abuts against the spiral blade 14 is fixed at the end of the movable rod 24, an elastic component connected to the movable rod 24 is provided on the fixed sleeve 23, wherein the elastic component includes a slot 2301 opened on the inner wall of the fixed sleeve 23, a fixed block 2401 slidably connected to the slot 2301 is fixed on the movable rod 24, and a spring 25 that abuts against the movable rod 24 is fixed in the fixed sleeve 23.

[0047] Furthermore, before drilling starts, the limiting block 19 is located at the middle position of the spiral groove 1201, such that the interleaving angle between the spiral cleaning piece 22 and the spiral blade 14 is maximized, so that the distances between both sides of the spiral cleaning piece 22 and both sides of the spiral blade 14 are equal. The spring 25 is in a compressed state, causing the movable rod 24 to have a tendency to move away from the fixed sleeve 23, so that the fixed block 2401 is at the end of the stroke on one side of the card slot 2301. Under the action of the fixed block 2401 and the card slot 2301, it is ensured that the movable rod 24 does not disengage from the fixed sleeve 23. At this time, the distance between the two cleaning plates 26 is the largest, and the distances between the two cleaning plates 26 and the corresponding spiral blade 14 are equal, and they are in a separated state from the spiral blade 14; when it is necessary to drill the foundation, the spiral blade 14 can transport the soil generated by drilling to the outside of the hole. During the transportation process, the soil and mud with greater viscosity will adhere to both the inner and outer sides of the spiral blade 14, which will cause the transportation rate of the spiral blade 14 to decrease and increase the load on the second motor 11. Therefore, under the action of the mud cleaning mechanism, the spiral cleaning piece 22 and the spiral blade 14 can be controlled to rotate with a differential speed to continuously adjust the interleaving angle between the spiral cleaning piece 22 and the spiral blade 14. The spiral cleaning piece 22 will also drive the fixed sleeve 23 to move and move towards one side of the spiral blade 14. Under the action of the fixed sleeve 23, the spring 25 is used to control the synchronous movement of the movable rod 24, thereby driving the cleaning plate 26 to move. When one of the cleaning plates 26 moves to fit one side of the spiral blade 14, since the spiral cleaning piece 22 and the spiral blade 14 are still rotating with a differential speed, the fixed sleeve 23 will continue to move and compress the spring 25. At the same time, the cleaning plate 26 will slide relatively on the surface of the spiral blade 14 to scrape the mud adhering to the spiral blade 14. When the interleaving angle between the spiral blade 14 and the spiral cleaning piece 22 reaches the minimum, the scraping area of the cleaning plate 26 on the mud on the spiral blade 14 reaches the maximum. At this time, the spiral cleaning piece 22 rotates towards the initial angle to control the other cleaning plate 26 to scrape the mud on the other side of the spiral blade 14. When the misalignment angle between the spiral blade 14 and the spiral cleaning piece 22 is the largest, both cleaning plates 26 and the spiral blade 14 are in a separated state. Only when the misalignment angle between the spiral cleaning piece 22 and the spiral blade 14 decreases, the corresponding cleaning plate 26 will clean the spiral blade 14.

[0048] Preferably, by controlling the differential rotation of the spiral cleaning blade 22 and the spiral blade 14, precise control of the two cleaning plates 26 can be achieved, enabling them to reciprocate alternately towards both sides of the spiral blade 14. During this process, the cleaning plates 26 can effectively scrape off the mud adhering to the spiral blade 14. This design effectively prevents the problems of reduced mud conveyance volume and increased mud conveyance difficulty of the spiral blade 14 caused by excessive mud adhesion on the spiral blade 14, ensuring the normal conveyance and discharge of mud during the drilling process and maintaining the continuity and stability of the drilling operation.

[0049] Please refer to Figures 1 - 5 , the lifting mechanism includes a first motor 5 fixed on the fixing plate 4, a lead screw 6 rotatably installed on the fixing plate 4 and connected to the output shaft of the first motor 5, a threaded sleeve 7 threadedly connected to the lead screw 6, and a sliding component connected to the threaded sleeve 7 arranged on the lifting plate 2. Among them, the sliding component includes a chute 201 opened on the lifting plate 2, a sliding plate 9 slidably installed in the chute 201, a connecting block 8 fixed on the sliding plate 9 and fixedly connected to the threaded sleeve 7, and the sliding plate 9 is fixedly connected to the movable plate 10.

[0050] Furthermore, in the initial state, the threaded sleeve 7 is located at the end of the stroke away from the machine table 1, so that the drill bit 13 is located at the end of the stroke away from the foundation. When drilling treatment is required, at this time, the first motor 5 operates and drives the lead screw 6 to rotate, thereby driving the threaded sleeve 7 to move. Under the action of the threaded sleeve 7, the sliding plate 9 is controlled to move along the length direction of the chute 201 through the connecting block 8, thereby driving the movable plate 10 to move. Under the action of the movable plate 10, the drilling assembly is controlled to move towards the foundation direction until the drilling of the foundation by the drilling assembly is completed. Among them, the lead screw 6 has an accurate transmission effect, which can ensure that the drilling assembly can smoothly drill to the required depth. At the same time, the lead screw 6 also has the characteristic of a slow transmission rate, which can prevent the problem of damage to the drill bit 13 caused by too fast drilling speed.

[0051] An automatic mud removal drilling machine method for ground foundation construction in open space includes the following steps:

[0052] Step 1: Control the movable plate 10 to move towards the ground direction through the lifting mechanism, and perform drilling treatment on the foundation through the drilling assembly;

[0053] Step 2: Under the action of the drilling assembly, control the spiral blade 14 to rotate to convey the mud generated by drilling and the like to the outside of the hole;

[0054] Step 3: Under the action of the mud cleaning mechanism, control the spiral cleaning blade 22 and the spiral blade 14 to perform differential rotation to clean the mud adhering to the drilling assembly through the spiral cleaning blade 22;

[0055] Step 4: The spiral cleaning blade 22 will also drive the blade cleaning mechanism to move, so as to clean the mud adhering to the spiral blade 14.
