Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and more specifically, to a cast-in-place pile construction device. Background Art

[0002] Cast-in-place piles are piles made by drilling holes at the designed pile positions and pouring concrete. Cast-in-place piles can be divided into bored cast-in-place piles, pipe sinking cast-in-place piles, and manually dug cast-in-place piles, etc. Bored cast-in-place piles are widely used in the field of construction engineering due to their low cost and simple construction operations.

[0003] At present, during the construction of offshore bored piles, the process is usually pile position layout, construction platform erection, steel casing burial, punching operation, hole cleaning, steel cage installation, conduit installation and underwater concrete pouring. The sinking quality of the steel casing will directly affect the quality of the bored pile. Therefore, ensuring the sinking accuracy of the steel casing, that is, the plane position and verticality, is the key and difficulty of the steel casing sinking. In addition, during the lowering of the steel cage, the steel cage will also be offset due to crane vibration or wind. In patent document 202310254816.6, a steel cage positioning auxiliary device and construction method for bored pile steel cage lowering is disclosed. However, the positioning auxiliary device disclosed in this comparative document cannot be applied to offshore bored pile construction, and the limited positioning device cannot guarantee the verticality of the sinking direction of the steel cage. Summary of the invention

[0004] The invention provides a cast-in-place pile construction device, which can guide sinking objects with different diameters and ensure their verticality.

[0005] In order to achieve these purposes and other advantages of the present invention, a cast-in-place pile construction device is provided, comprising:

[0006] Drilling platform;

[0007] There are six rotating wheel components, which are arranged on the drilling platform around the pile hole at equal intervals, and each rotating wheel component includes: a base fixed on the drilling platform; a support column arranged on the base in a manner that it can move forward and backward; a rotating wheel arranged on the top of the support column, and arc-shaped protrusions are arranged on the rim of the rotating wheel at equal intervals;

[0008] Among them, the wheels of three non-adjacent wheel components are located at the same horizontal height, which is the first group of wheels; the wheels of the remaining three non-adjacent wheel components are located at another horizontal height, which is the second group of wheels, and the horizontal height of the first group of wheels is greater than the horizontal height of the second group of wheels; by adjusting the position of the movable support column, the internal space surrounded by the six wheels can accommodate construction objects of different diameters that need to sink into the pile hole, guide the sinking construction objects and ensure their verticality.

[0009] Preferably, in the cast-in-place pile construction device, the construction object is a steel casing, and when the steel casing is sunk into the pile hole, two sets of wheels located at different heights clamp the steel casing so that the center position of the steel casing will not deviate when it sinks.

[0010] Preferably, in the cast-in-place pile construction device, the construction object is a steel cage. When the steel cage is sunk into the steel casing, the arcuate protrusions of the six rotating wheels are matched with the spacing between the stirrups of the steel cage, so that the arcuate protrusions are stuck between the stirrups of the steel cage. When the steel cage is sunk, the sunken steel cage drives the six rotating wheels to rotate, so that the arcuate protrusions are stuck between the stirrups of the steel cage one by one, ensuring that the center position of the sunken steel cage will not deviate.

[0011] Preferably, in the cast-in-place pile construction device, the support column comprises a first column body arranged at the top and a second column body arranged at the bottom, a first cylindrical groove is arranged at the center position of the bottom surface of the first column body and the center position of the top surface of the second column body, a steel spring is arranged in the two first cylindrical grooves to connect the first column body and the second column together; a plurality of second cylindrical grooves are arranged on the bottom surface of the first column body around the first cylindrical groove, internal threads are arranged on the groove walls of the plurality of second cylindrical grooves, a first bolt is arranged in each of the second cylindrical grooves, and the verticality and height of the first column body can be adjusted by rotating the plurality of first bolts.

[0012] Preferably, in the cast-in-place pile construction device, the rotating wheel includes a main shaft and a wheel body connected to the main shaft bearing, the top of the support column is provided with a square groove, and two side walls opposite to each other of the square groove are provided with a through hole, and the two end heads of the main shaft respectively pass through the through holes and are fixed to the through holes, wherein a transparent first liquid box is provided above one of the end heads of the main shaft, and a plurality of scale lines are provided on the first liquid box, and whether the main shaft of the rotating wheel is tilted is judged by judging the coincidence degree between the liquid and the scale lines, and if tilted, the first bolt under the first column is adjusted to make the main shaft in a horizontal position.

[0013] Preferably, the cast-in-place pile construction device also includes three arc-shaped square rods, and a transparent second liquid box is arranged above each arc-shaped square rod, wherein a first protrusion is arranged at both end heads of the arc-shaped square rod, and a first groove matched with the first protrusion is arranged at both end heads of the main shaft of each of the rotating wheels. The three arc-shaped square rods connect the first group of rotating wheels or the second group of rotating wheels, and by judging whether the liquid in the second liquid box coincides with the scale line on the second liquid box, it is judged whether the three rotating wheels in the first group of rotating wheels or the second group of rotating wheels are at the same level. If not, the first bolt under the first column is adjusted to make the three rotating wheels in the first group of rotating wheels or the second group of rotating wheels at the same level.

[0014] Preferably, in the cast-in-place pile construction device, the support column is arranged on the base in a manner that it can move forward and backward, specifically: a screw is arranged in the internal cavity of the base, the screw is connected to the output shaft of a motor, a fixed block is arranged on the screw, the fixed block passes through the elongated hole on the top surface of the base and is fixedly connected to the support column; a slide rail is arranged on both sides of the elongated hole on the top surface of the base, and a slider compatible with the slide rail is arranged on the bottom surface of the support column.

[0015] Preferably, in the cast-in-place pile construction device, the horizontal height of the first set of wheels is 1 to 1.5 meters higher than the horizontal height of the second set of wheels.

[0016] Preferably, in the cast-in-place pile construction device, the number of the second cylindrical grooves is 4 or 6.

[0017] The present invention has at least the following beneficial effects:

[0018] First, since there are six rotating wheel components and they are divided into two groups, the rotating wheels of three non-adjacent rotating wheel components are located at the same horizontal height, which are the first group of rotating wheels; the rotating wheels of the remaining three non-adjacent rotating wheel components are located at another horizontal height, which are the second group of rotating wheels. The six rotating wheels can surround and form an internal space. The advantage of such a configuration is that the three rotating wheels located at the same height can tighten the construction object placed in the internal space, and the two groups of rotating wheels at different horizontal heights can ensure the verticality of the construction object. The rotation of the rotating wheel can make the construction object sink. When the construction object moves downward, it will not deviate from the center position of the construction object due to the restriction of the six rotating wheels.

[0019] Secondly, arc-shaped protrusions are arranged at equal intervals on the wheel rim. When the sinking construction object is a steel cage, a part of the arc-shaped protrusion is stuck between the stirrups of the steel cage, so that the steel cage can be tightened. When the steel cage sinks and moves downward due to gravity, it can also drive the six wheels to rotate, so that the arc-shaped protrusions are stuck between the stirrups of the steel cage one by one, which not only limits the descending speed of the steel cage, but also ensures that the center position of the sinking steel cage will not deviate.

[0020] Third, since the drilling platform cannot guarantee its horizontality, after the base is fixed on the drilling platform, it cannot guarantee that the verticality of the support column and the three wheels in each group are at the same horizontal height. Therefore, the present invention divides the support column into a first column and a second column, which are connected by a steel spring, so that the verticality of the first column can be changed. A plurality of second cylindrical grooves are arranged around the first cylindrical groove on the bottom surface of the first column, and the groove wall of the second cylindrical groove is also provided with an internal thread. Therefore, by rotating the first bolt arranged in the second cylindrical groove, the verticality and height of the first column can be adjusted, and the three wheels in each group are further guaranteed to be at the same horizontal height.

[0021] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through study and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figure 1 to Figure 3 As shown, an embodiment of the present invention provides a cast-in-place pile construction device, including: a drilling platform 8; six rotating wheel components, which are arranged on the drilling platform 8 around the pile hole 9 at equal intervals, and each of the rotating wheel components includes: a base 1, which is fixed on the drilling platform 8; a support column 2, which is arranged on the base 1 in a manner that it can move forward and backward; a rotating wheel 3, which is arranged on the top of the support column 2, and arc-shaped protrusions 303 are arranged on the rim of the rotating wheel 3 at equal intervals; wherein the rotating wheels 3 of three non-adjacent rotating wheel components are arranged on the same side. The six wheels 3 are located at the same horizontal height, which is the first group of wheels; the wheels 3 of the remaining three non-adjacent wheel components are located at another horizontal height, which is the second group of wheels, and the horizontal height of the first group of wheels is greater than that of the second group of wheels. Preferably, the horizontal height of the first group of wheels is 1 to 1.5 meters higher than that of the second group of wheels; by adjusting the position of the movable support column 2, the internal space surrounded by the six wheels 3 can accommodate construction objects of different diameters that need to be sunk into the pile hole 9, guide the sunken construction objects and ensure their verticality.

[0029] In the above embodiment, since there are six runner components and they are divided into two groups, the runners 3 of three non-adjacent runner components are located at the same horizontal height, which is the first group of runners; the runners 3 of the remaining three non-adjacent runner components are located at another horizontal height, which is the second group of runners. The six runners 3 can surround an internal space. The advantage of such a setting is that the three runners 3 located at the same height can tighten the construction object placed in the internal space, and the two groups of runners 3 at different horizontal heights can ensure the verticality of the construction object. The rotation of the runner 3 can make the construction object sink. When the construction object moves downward, due to the limitation of the six runners 3, the center position of the construction object will not deviate. In the specific implementation, the construction preparation is first carried out, and then the pile position is set out, and then the drilling platform 8 is built on the sea, and the base 1 is evenly fixed around the pile position hole to be drilled. When the position of the support column 2 is adjusted, the internal space surrounded by the six runners 3 can accommodate sinking construction objects of different diameters. Therefore, the sinking construction object can be a steel casing or a steel cage. The cross section of the support column 2 can be rectangular or square. The base 1 is fixed on the drilling platform 8 by bolts, so as to facilitate the later disassembly. Since the horizontal heights of the wheels 3 in the two groups of wheels are different, the heights of the support columns 2 provided in the two groups are also different.

[0030] In one specific embodiment, in the cast-in-place pile construction device, the construction object is a steel casing. When the steel casing is sunk into the pile hole 9, two sets of wheels at different heights clamp the steel casing so that the center position of the steel casing will not deviate when it sinks.

[0031] In specific implementation, a vibrating hammer is needed to vibrate the steel casing to sink it, so the center position of the steel casing is easily deviated. When two sets of wheels 3 at different heights are used for guidance, the center position of the steel casing will never change and will not deviate.

[0032] In one specific embodiment, in the cast-in-place pile construction device, the construction object is a steel cage. When the steel cage is sunk into the steel casing, the arcuate protrusions of the six rotating wheels 3 are matched with the spacing between the stirrups of the steel cage, so that the arcuate protrusions 303 are stuck between the stirrups of the steel cage. When the steel cage is sunk, the sunken steel cage drives the six rotating wheels 3 to rotate, so that the arcuate protrusions 303 are stuck one by one between the stirrups of the steel cage, ensuring that the center position of the sunken steel cage will not deviate.

[0033] In specific implementation, when the steel casing is settled, punched and cleaned, the steel cage begins to sink. At this time, the support column 2 needs to be moved to adjust the diameter of the internal space surrounded by the six wheels 3 so that the arc-shaped protrusion 303 can be stuck between the stirrups of the steel cage. In specific settings, the diameter of the wheel 3 is preferably 50 to 60 cm, which is not particularly limited in this embodiment and can be specifically set according to actual conditions.

[0034] In one specific embodiment, the cast-in-place pile construction device, the support column 2 includes a first column 201 arranged at the top and a second column 202 arranged at the bottom, a first cylindrical groove 4 is arranged at the center position of the bottom surface of the first column 201 and the center position of the top surface of the second column 202, a steel spring 5 is arranged in the two first cylindrical grooves 4 to connect the first column 201 and the second column 202 together; a plurality of second cylindrical grooves 6 are arranged on the bottom surface of the first column 201 around the first cylindrical groove 4, internal threads are arranged on the groove walls of the plurality of second cylindrical grooves 6, a first bolt 7 is arranged in each of the second cylindrical grooves 6, and the verticality and height of the first column 201 can be adjusted by rotating the plurality of first bolts 7. Preferably, the number of the second cylindrical grooves 6 is 4 or 6.

[0035] In the above embodiment, the drilling platform 8 cannot guarantee its horizontality. After the base 1 is fixed on the drilling platform 8, it cannot guarantee the verticality of the support column 2 and the three wheels 3 in each group are at the same horizontal height. Therefore, in this embodiment, the support column 2 is divided into a first column 201 and a second column 202, which are connected by a steel spring 5, so that the verticality of the first column 201 can be changed. A plurality of second cylindrical grooves 6 are arranged around the first cylindrical groove 4 on the bottom surface of the first column 201, and the groove wall of the second cylindrical groove 6 is also provided with an internal thread. Therefore, by rotating the first bolt 7 arranged in the second cylindrical groove 6, the verticality and height of the first column 201 can be adjusted, and the three wheels 3 in each group are further guaranteed to be at the same horizontal height.

[0036] In one specific embodiment, the cast-in-place pile construction device, the rotating wheel 3 includes a main shaft 301 and a wheel body 302 connected to the main shaft 301 bearing, the top of the support column 2 is provided with a square groove, and a through hole is provided on the two opposite side walls of the square groove, and the two end heads of the main shaft 301 respectively pass through the through holes and are fixed to the through holes, wherein a transparent first liquid box is provided above one of the end heads of the main shaft 301, and a plurality of scale lines are provided on the first liquid box, and whether the main shaft 301 of the rotating wheel 3 is tilted is judged by judging the coincidence degree between the liquid and the scale lines, and if tilted, the first bolt 7 under the first column 201 is adjusted to make the main shaft 301 in a horizontal position.

[0037] In specific implementation, some water or other liquid is placed in the first liquid box, and several more horizontal scale lines can be set on the first liquid box, with the spacing as dense as possible. With such a setting, it is easy to judge whether the main shaft 301 of the rotating wheel 3 is tilted. If the main shaft 301 is tilted, the rim of the rotating wheel 3 will be tilted, which will further affect the verticality of the construction object. Therefore, it is very important to ensure the horizontality of the main shaft 301. Before sinking the construction object, the horizontality of the main shaft 301 of each rotating wheel 3 needs to be checked one by one. In specific setting, the main shaft 301 can be fixed to the through hole by welding or bolts, so that the rotating wheel 3 is fixed on the support column 2.

[0038] In one specific embodiment, Figure 3 As shown, the cast-in-place pile construction device also includes three arc-shaped square rods 10, and a transparent second liquid box 12 is arranged above each arc-shaped square rod 10, wherein a first protrusion 11 is arranged at both ends of the arc-shaped square rod 10, and a first groove 304 matched with the first protrusion 11 is arranged at both ends of the main shaft 301 of each of the runners 3. The three arc-shaped square rods 10 connect the first group of runners or the second group of runners. By judging whether the liquid in the second liquid box 12 coincides with the scale line on the second liquid box 12, it is judged whether the three runners 3 in the first group of runners or the second group of runners are at the same horizontal height. If not, the first bolt 7 under the first column 201 is adjusted to make the three runners 3 in the first group of runners 3 or the second group of runners 3 at the same horizontal height.

[0039] In the above embodiment, since the six rotating wheels 3 are evenly spaced around the pile hole 9, when three arc-shaped square rods 10 are used to measure whether the three rotating wheels 3 are at the same level, the first group of rotating wheels can be directly measured, so that the first protrusions 11 at both ends of the square rods 10 are respectively located in the first grooves 304 on the ends of the two main shafts 301 in the first group of rotating wheels, so that the three square rods 10 connect the main shafts 301 of the three rotating wheels 3 together. However, if the second group of rotating wheels is measured whether it is at the same level, the three rotating wheels 3 in the first group of rotating wheels need to be moved away from the pile hole 9, so that the square rods 10 can connect the main shafts 301 of the three rotating wheels 3 in the second group of rotating wheels together.

[0040] In one specific embodiment, the cast-in-place pile construction device, the support column 2 is arranged on the base 1 in a manner that it can move forward and backward, specifically: a screw 101 is arranged in the internal cavity of the base 1, the screw 101 is connected to the output shaft of a motor 102, a fixed block 103 is arranged on the screw 101, the fixed block 103 passes through the long strip hole on the top surface of the base 1 and is fixedly connected to the bottom surface of the support column 2; a slide rail 104 is arranged on both sides of the long strip hole on the top surface of the base 1, and a slider 105 adapted to the slide rail 104 is arranged on the bottom surface of the support column 2. The fixed block 103 is fixed to the bottom surface of the support column 2 by welding. The base 1, the fixed block 103 and the support column 2 are all made of steel.

[0041] In summary, the bored pile construction device provided by the present invention can guide sinking objects of different diameters and ensure their verticality.

[0042] The number of devices and processing scales described here are used to simplify the description of the present invention. Applications, modifications and variations of the present invention will be obvious to those skilled in the art.

[0043] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
