Description

Technical Field

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

[0002] Foundation drilling is a common construction technology in construction projects, 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 to protect the hole wall and prevent it from collapsing or shrinking. At the same time, the mud circulation can absorb some heat to cool the drill tool and reduce wear.

[0004] However, the mud and the soil produced by drilling will mix with each other, resulting in an increase in the viscosity of the mud. The mud may adhere to the drill rod during the cleaning process. The soil adhering to the spiral blade shaft (drill rod) will increase the friction between the drill rod and the soil, requiring the drill rig to have greater power to overcome the resistance during the drilling process, resulting in reduced construction efficiency. In addition, during the rotation and lifting of the drill rod and drill bit, the stress they are subjected to will increase accordingly due to the adhesion of the mud, which will accelerate the wear of the drill rod and drill bit, affect the efficiency and quality of drilling, and may even cause damage to the drill rod and drill bit. In order to overcome the above-mentioned defects, the prior art usually takes out the drill rod for cleaning. However, this technical means requires the drill rod to be taken out for corresponding cleaning at intervals, thereby reducing work efficiency. Summary of the invention

[0012] As a further solution of the present invention: the elastic component includes a slot provided on the inner wall of the fixed sleeve, a fixed block slidably connected to the slot is fixed on the movable rod, and a spring abutting against the movable rod is fixed in the fixed sleeve.

[0013] As a further solution of the present invention: the lifting mechanism includes a first motor fixed on the fixed plate, a screw connected to the output shaft of the first motor is rotatably installed on the fixed plate, a threaded sleeve is threadedly connected to the screw, and a sliding assembly connected to the threaded sleeve is provided on the lifting plate.

[0014] As a further solution of the present invention: the sliding assembly includes a sliding groove opened on the lifting plate, a sliding plate is slidably installed in the sliding groove, a connecting block fixedly connected to the threaded sleeve is fixed on the sliding plate, and the sliding plate is fixedly connected to the movable plate.

[0015] An automatic mud removal drilling machine method for vacant land foundation construction comprises the following steps: Step 1: Control the movable plate to move toward the ground through the lifting mechanism, and drill holes in the foundation through the drilling assembly; Step 2: Under the action of the drilling assembly, the spiral blade is controlled to rotate to transport the mud generated by drilling to the outside of the hole; Step 3: Under the action of the mud cleaning mechanism, the spiral cleaning sheet and the spiral blade are controlled to rotate at a differential speed, so as to clean the mud adhering to the drilling assembly through the spiral cleaning sheet; Step 4: The spiral cleaning piece will also drive the blade cleaning mechanism to move to clean the mud adhering to the spiral blade.

Specifically, when the lifting mechanism is working, the drilling assembly is driven to move by the movable plate, so that the foundation is drilled by the drilling assembly. At the same time, under the action of the mud cleaning mechanism, the mud adhered to the drilling assembly is cleaned, and the mud cleaning mechanism will also drive the blade cleaning mechanism to move to clean the mud adhered to the spiral blade. By cleaning the mud adhered to the drilling assembly and the spiral blade, higher drilling accuracy can be ensured.

[0017] By controlling the movable sleeve to reciprocate along the length of the drill pipe, the differential rotation of the spiral cleaning piece and the spiral blade can be achieved, thereby changing the staggered angle between the spiral cleaning piece and the spiral blade. In this process, the spiral cleaning piece can effectively scrape the mud adhering to the drill pipe, prevent the accumulation of mud on the drill pipe, ensure the balance of the drill pipe and the drill bit during rotation, and significantly reduce the stress and wear of the drill pipe during rotation and lifting, effectively extending the service life of the drill pipe and reducing the maintenance cost and replacement frequency of the equipment.

[0018] By controlling the spiral cleaning sheet and the spiral blade to rotate at a differential speed, the two cleaning plates can be precisely controlled to make them reciprocate alternately toward the two sides of the spiral blade. In this process, the cleaning plate can effectively scrape off the mud adhering to the spiral blade, thus preventing the problem of reduced mud transport volume and increased difficulty in mud transport caused by excessive mud adhering to the spiral blade.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0023] See also Figure 1 to Figure 10 In an embodiment of the present invention, an automatic mud removal drilling machine device for paving a foundation in an open space includes: a machine platform 1, and a lifting plate 2 fixed on the machine platform 1, and a fixed plate 4 is fixed on the lifting plate 2; it also includes: a lifting mechanism, which is arranged on the fixed plate 4, and a movable plate 10 is connected to the lifting mechanism, and a drilling assembly is arranged on the movable plate 10, and a spiral blade 14 is connected to the drilling assembly; a mud cleaning mechanism is arranged on the drilling assembly, and a spiral cleaning piece 22 is connected to the mud cleaning mechanism, and a blade cleaning mechanism is arranged on the spiral cleaning piece 22, and the mud cleaning mechanism can drive the spiral cleaning piece 22 to perform differential rotation when the spiral blade 14 rotates, and perform a cleaning action on the spiral blade 14 through the blade cleaning mechanism.

[0024] Specifically, the machine 1 is fixed with a support column 3 fixedly connected to the lifting plate 2. Under the action of the support column 3, the support force of the lifting plate 2 is increased. When drilling the foundation, the machine 1 can be controlled to move to the desired drilling position. At the same time, the lifting mechanism works and drives the drilling assembly to move toward the foundation 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 and enter the borehole. Under the action of the spiral blade 14, the mud generated by the drilling is discharged from the hole. In the drilling process, the mud cleaning mechanism will control the spiral cleaning piece 22 and the spiral blade 14 to rotate differentially to clean the mud adhered to the drilling assembly. The mud cleaning mechanism will also drive the blade cleaning mechanism to move to clean the mud adhered to the spiral blade 14. In particular, when drilling the foundation, the mud generated during the drilling process is easy to adhere 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 process of the drilling assembly, due to the adhesion of mud, the stress it is subjected to will also increase accordingly, which will accelerate the wear of the drilling assembly, affect the efficiency and quality of drilling, and may even cause damage to the drilling assembly. However, the present application can achieve timely and effective cleaning of the mud adhered to the spiral blade 14 and the drilling assembly by controlling the differential rotation of the spiral cleaning sheet 22 and the spiral blade 14, and driving the mud cleaning mechanism to move in coordination. This process can not only keep the drilling assembly clean, avoid the problems of increased weight and reduced balance caused by mud adhesion, but also significantly reduce the stress of the drilling assembly during the rotation and lifting process, thereby reducing wear, extending the service life of the drilling assembly, and ensuring that the drilled hole can meet the various requirements required for construction.

[0025] See also Figure 1-Figure 5 , Figure 7 The drilling assembly includes a second motor 11 fixedly mounted on the movable plate 10, a drill rod 12 connected to the output shaft of the second motor 11 is rotatably mounted on the movable plate 10, the drill rod 12 is fixedly connected to the spiral blade 14, and a drill bit 13 is fixed to the end of the drill rod 12.

[0026] In detail, before drilling the foundation, the movable plate 10 can be controlled by the lifting mechanism to move toward the foundation, thereby driving the drill rod 12 and the drill bit 13 to move. When the drill bit 13 abuts against the foundation, the second motor 11 works and drives the drill bit 13 to rotate through the drill rod 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 to protect the hole wall and prevent the hole wall from collapsing or shrinking. At the same time, the mud circulates and carries the slag to the designated location to keep the borehole clean. During the drilling process of the drill bit 13, a large amount of heat will be generated. The mud circulation can absorb part of the heat to cool the drill tool and reduce wear.

[0027] See also Figure 1-Figure 5 , Figure 7 , Fig. 9 , Fig.10 The mud cleaning mechanism includes a guide column 15 fixed on the movable plate 10, a receiving plate 21 is fixed at the end of the guide column 15, a rotating sleeve 20 is rotatably mounted on the receiving plate 21, one end of the rotating sleeve 20 is fixedly connected to the spiral cleaning sheet 22 and is sleeved on the drill rod 12, and a pushing assembly connected to the guide column 15 is provided on the movable plate 10, wherein the pushing assembly includes a cylinder 16 fixed on the movable plate 10, a pushing plate 17 slidably connected to the guide column 15 is fixed at the telescopic end of the cylinder 16, a movable sleeve 18 slidably connected to the rotating sleeve 20 is rotatably mounted on the pushing plate 17, and the pushing assembly also includes a spiral groove 1201 opened on the circumferential outer wall of the drill rod 12, and a limit block 19 slidably engaged with the spiral groove 1201 is fixed on the inner wall of the movable sleeve 18.

[0028] Among them, before the spiral blade 14 and the spiral cleaning sheet 22 are installed, since the pitches of the two are equal, the two can be controlled to be combined with each other in a spirally screwed manner. After the combination is completed, the two are synchronously controlled to be sleeved on the drill rod 12, and the two are staggered at a certain angle. At this time, the spiral blade 14 can be fixed to the drill rod 12 by welding or other means. When the rotating sleeve 20 is sleeved on the drill rod 12 and is located at the desired working position, the spiral cleaning sheet 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 sheet 22.

[0029] It should be noted that a limit groove 1801 is provided on the inner wall of the movable sleeve 18, and a limit rod 2001 is fixed on the outer wall of the rotating sleeve 20, which is slidably engaged with the limit groove 1801. The pitch of the spiral cleaning piece 22 is the same as that of the spiral blade 14. Before drilling, under the action of the cylinder 16, the movable sleeve 18 is controlled to be in a fixed state through the push plate 17, so that the limit block 19 is located in the middle position of the spiral groove 1201. Under the action of the rotating sleeve 20, the spiral cleaning piece 22 and the spiral blade 14 are arranged in a staggered shape, and the staggered angle difference is half a circle; when it is necessary to drill a hole in the foundation, at this time, under the action of the lifting mechanism, the drill bit 13 is controlled to move toward the direction of the foundation, 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, and the drill bit 13 will drill the foundation. The spiral blade 1 When entering the borehole, the soil generated by the borehole can be transported to the outside of the borehole. At the same time, since the position of the limit block 19 in the spiral groove 1201 will not change, under the action of the limit block 19 and the spiral groove 1201, the movable sleeve 18 rotates synchronously with the drill rod 12, thereby driving the rotating sleeve 20 to rotate through the limit groove 1801 and the limit rod 2001, so as to drive the spiral cleaning piece 22 to rotate synchronously with the spiral blade 14; it should be emphasized that the cylinder 16 controls the position of the push plate 17 to remain unchanged, so that the height of the movable sleeve 18 and the limit block 19 on the drill rod 12 remains 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 limit block 19, and the corresponding position of the limit block 19 in the spiral groove 1201 will not change.

[0030] During the drilling process, mud needs to be added to ensure the normal use of the drill bit 13, and the mud will be mixed with the drilled soil, resulting in an increase in the viscosity of the mud and soil. During the process of the spiral blade 14 transporting the mud and soil, the soil and mud may adhere to the drill rod 12 and the spiral blade 14. Therefore, the mud and soil need to be cleaned. At this time, under the action of the cylinder 16, the push plate 17 is controlled to move along the length direction of the guide column 15 and move in a direction 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 trajectory of the spiral groove 1201 and increase the size of the fit with the rotating sleeve 20. Under the action of the limit block 19 and the spiral groove 1201, the movable sleeve 18 is rotated by a certain angle relative to the drill rod 12 itself to pass through the limit groove 1801 and the limit rod 2 001 drives the rotating sleeve 20 to rotate a certain angle relative to the drill rod 12. Under the action of the rotating sleeve 20, the spiral cleaning piece 22 and the spiral blade 14 produce differential rotation. Therefore, the staggered angle of 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 rod 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 of the spiral cleaning piece 22 and the spiral blade 14 reaches the minimum, and a part of the drill rod 12 is cleaned. At this time, the cylinder 16 controls the movable sleeve 18 to reset and move toward 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. The staggered angle of the spiral cleaning piece 22 and the spiral blade 14 reaches the minimum again, and another part of the drill rod 12 is cleaned.

[0031] Preferably, by controlling the movable sleeve 18 to reciprocate along the length direction of the drill rod 12, the differential rotation of the spiral cleaning piece 22 and the spiral blade 14 can be achieved, thereby changing the staggered angle between the spiral cleaning piece 22 and the spiral blade 14. In this process, the spiral cleaning piece 22 can effectively scrape off the mud adhering to the drill rod 12. This design not only prevents the accumulation of mud on the drill rod 12, ensures the balance of the drill rod 12 and the drill bit 13 during the rotation process, but also significantly reduces the stress and wear of the drill rod 12 during the rotation and lifting process, effectively prolongs the service life of the drill rod 12, and reduces the maintenance cost and replacement frequency of the equipment.

[0032] In addition, during the mud cleaning process, the amount of mud adhering to the drill rod 12 is reduced, and the load of the second motor 11 when driving the drill rod 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.

[0033] See also Figure 1-Figure 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.

[0034] Furthermore, before drilling begins, the stopper 19 is located in the middle of the spiral groove 1201, so that the staggered angle between the spiral cleaning piece 22 and the spiral blade 14 is maximized, so that the spacing between the two sides of the spiral cleaning piece 22 and the two sides of the spiral blade 14 is equal, and the spring 25 is in a compressed state, so that the movable rod 24 has a tendency to move away from the fixed sleeve 23, so that the fixed block 2401 is located at the end of the stroke on one side of the slot 2301. Under the action of the fixed block 2401 and the slot 2301, it is ensured that the movable rod 24 will not be separated from the fixed sleeve 23. At this time, the space between the two cleaning plates 26 is The spacing is the largest, and the distances between the two cleaning plates 26 and the corresponding spiral blades 14 are equal, and they are separated from the spiral blades 14; when it is necessary to drill a hole in the foundation, the soil produced by the drilling can be transported to the outside of the hole through the spiral blades 14. During the transportation process, the soil and mud with greater viscosity will adhere to the inner and outer sides of the spiral blades 14, which will cause the conveying rate of the spiral blades 14 to decrease and increase the load of 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 produce differential rotation to continuously adjust the spiral cleaning piece 22 and the spiral blade The spiral cleaning sheet 22 also drives the fixed sleeve 23 to move and move toward one side of the spiral blade 14. Under the action of the fixed sleeve 23, the spring 25 controls 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 sheet 22 and the spiral blade 14 are still in a differential rotation state, 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 clean the adhered to the spiral blade 14. The mud is scraped off. When the staggered angle between the spiral blade 14 and the spiral cleaning sheet 22 reaches the minimum, the scraping area of ​​the mud on the spiral blade 14 by the cleaning plate 26 reaches the maximum. At this time, the spiral cleaning sheet 22 rotates toward 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 sheet 22 is the largest, the two cleaning plates 26 and the spiral blade 14 are in a separated state. Only when the misalignment angle between the spiral cleaning sheet 22 and the spiral blade 14 is reduced, the corresponding cleaning plate 26 will clean the spiral blade 14.

[0035] Preferably, by controlling the spiral cleaning sheet 22 and the spiral blade 14 to rotate at a differential speed, the two cleaning plates 26 can be precisely controlled so that they alternately reciprocate toward the two sides of the spiral blade 14. In this process, the cleaning plate 26 can effectively scrape off the mud adhering to the spiral blade 14. This design effectively prevents the problem of reduced mud transport amount and increased difficulty of mud transport caused by excessive mud adhering to the spiral blade 14, ensures the normal transport and discharge of mud during the drilling process, and maintains the continuity and stability of the drilling operation.

[0036] See also Figure 1-Figure 5 The lifting mechanism includes a first motor 5 fixed on the fixed plate 4, a screw rod 6 connected to the output shaft of the first motor 5 is rotatably installed on the fixed plate 4, a threaded sleeve 7 is threadedly connected to the screw rod 6, and a sliding component connected to the threaded sleeve 7 is provided on the lifting plate 2, wherein the sliding component includes a sliding groove 201 opened on the lifting plate 2, a sliding plate 9 is slidably installed in the sliding groove 201, a connecting block 8 fixedly connected to the threaded sleeve 7 is fixed on the sliding plate 9, and the sliding plate 9 is fixedly connected to the movable plate 10.

[0037] To go further, in the initial state, the threaded sleeve 7 is located at the end of the stroke away from the machine 1, so that the drill bit 13 is located at the end of the stroke away from the foundation. When drilling is required, the first motor 5 works and drives the screw rod 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 by the connecting block 8 to move along the length direction of the slide groove 201, thereby driving the movable plate 10 to move. Under the action of the movable plate 10, the drilling assembly is controlled to move toward the foundation until the drilling assembly completes drilling the foundation. Among them, the screw rod 6 has a precise transmission effect, which can ensure that the drilling assembly can drill to the required depth smoothly. At the same time, the screw rod 6 also has the characteristic of slow transmission speed, which can prevent the drill bit 13 from being damaged due to excessive drilling speed.
