Description

Technical Field

[0001] This invention relates to a BIM-based intelligent guidance and positioning system for pile cutting machines. Background Technology

[0002] A pile cutter is a type of engineering machinery suitable for quickly removing pile heads in pile foundation engineering. It is applicable to the removal of pile heads of various pile foundation types. The pile cutter uses a power source to provide pressure to multiple hydraulic cylinders, which directly drive the chisel rod, simultaneously squeezing the pile body to cut off the pile head. Currently available simple hydraulic pile cutter devices require a large-tonnage (≥20T) crane to pull out the pile head. Furthermore, these devices cannot maintain a horizontal position, resulting in inaccurate positioning and tilted pile head sections. This necessitates further manual processing, leading to high labor and machine costs, significant construction safety risks, and low levels of mechanization. Summary of the Invention

[0004] To address the above problems, this invention provides a BIM-based intelligent guidance and positioning system for pile cutting machines, comprising:

[0005] The positioning device installed on the annular pile head of the ring-type hydraulic pile cutting system of the pile cutter is used to collect the position information of the annular pile head in real time.

[0006] The guide locator, installed in the driver's control room of the pile cutter, is used to receive the position information of the ring-shaped pile head from the positioning device, and align the position of the ring-shaped pile head with the preset position of the pile head based on the position information of the ring-shaped pile head, the BIM model of the pile cutter, and the BIM model of the pile head.

[0007] Furthermore, in the above system, the positioning device includes: a positioning chip, an image measuring instrument, and a positioning data transmission device disposed on the annular pile head, wherein the positioning data transmission device is connected to the positioning chip, the image measuring instrument, and the guide locator, respectively.

[0008] Furthermore, in the above system, the guide locator includes: a touch screen, a wireless transmission device, a positioning data receiving device, and a data processing chip, wherein the data processing chip is connected to the touch screen, the wireless transmission device, and the positioning data receiving device respectively; the positioning data receiving device communicates with the positioning data transmission device, and the positioning data receiving device receives the position information of the annular pile head from the positioning data transmission device.

[0009] Furthermore, in the above system, the wireless transmission device is used to acquire the pile location BIM model and the pile cutting machine BIM model on site and import them into the guide locator.

[0010] The data processing chip is used to read the pile location BIM model and the pile cutting machine BIM model, and based on the pile location BIM model and the pile cutting machine BIM model, the data processing chip calculates the movement guide route of the pile cutting machine and the preset position of the pile head and displays it on the display screen; when the pile cutting machine moves to the vicinity of the preset position of the pile head according to the movement guide route, the position of the annular pile cutting head is aligned with the preset position of the pile head based on the position information of the annular pile cutting head.

[0011] Furthermore, in the above system, the positioning chip is used to collect the planar coordinates in the position information of the annular pile head, and the image measuring instrument is used to collect the height coordinates of the annular pile head in the position information.

[0012] Furthermore, in the above system, there are three image measuring instruments, which are arranged opposite each other on the annular pile head, with the three image measuring instruments spaced 90 degrees apart.

[0013] Furthermore, in the above system, there are three positioning chips, each of which is set on the annular truncated pile head corresponding to the location of an image measuring instrument.

[0014] Furthermore, in the above system, the coordinates of the known preset position of the pile head are (x, y, z);

[0015] The coordinates of the first positioning chip are A(x,y1,z1), and the coordinates of the stub at the front of the first positioning chip are a(x,y2,z). Among them, x and y1 of A(x,y1,z1) are acquired by the first positioning chip, and z1 of A(x,y1,z1) is acquired by the image measuring instrument at the position of the first positioning chip.

[0016] The coordinates of the second positioning chip are B(x,y4,z1), and the coordinates of the stub at the front of the second positioning chip are b(x,y3,z). Among them, x and y4 of B(x,y4,z1) are acquired by the second positioning chip, and z1 of B(x,y4,z1) is acquired by the image measuring instrument at the position of the second positioning chip.

[0018] Furthermore, in the above system, the data processing chip is used to indicate that the position of the annular pile head is aligned with the preset position of the pile head if the planar position is X+R=X1, Y+R=Y1 and the height position is Z=Z1.

[0019] Furthermore, in the above system, the data processing chip is also used to evaluate the pressure value applied by the pile cutter based on the parameter value of the pile strength in the pile location BIM model, so as to obtain the evaluated pressure value, and control the pile cutter to work based on the evaluated pressure value.

This invention achieves intelligent guidance and positioning of the pile cutter, which is of great significance for improving construction quality and realizing digital and intelligent construction and management.

[0021] This invention utilizes the construction parameter values ​​attached to the BIM model of the pile head to intelligently analyze and evaluate the pressure that the pile cutter needs to apply during operation, providing stronger data support for pile cutter construction.

[0022] This invention combines the BIM model of concrete cast-in-place pile design with the actual positioning data of the concrete cast-in-place pile. Before pile cutting, a guide locator is used to assist construction personnel in spatially positioning the pile location. Then, the positioning device corrects the horizontal displacement of the pile cutter. At the same time, the system uses engineering values ​​contained in the BIM model, such as the pile strength, to evaluate the pressure value that the pile cutter needs to apply, thereby achieving horizontal cutting of the pile head.

[0028] like Figures 1 to 4 As shown, this invention provides a BIM-based intelligent guidance and positioning system for pile cutting machines, comprising:

[0029] The positioning device installed on the annular pile head of the ring-type hydraulic pile cutting system of the pile cutter is used to collect the position information of the annular pile head in real time.

[0030] The guide locator 8, installed in the driver's control room of the pile cutter, is used to receive the position information of the annular pile head from the positioning device, and align the position of the annular pile head with the preset position of the pile head based on the position information of the annular pile head, the BIM model of the pile cutter, and the BIM model of the pile head.

[0031] Here, the system may include: a tracked mobile support system, a ring-type hydraulic pile cutting system, a pump station and hydraulic control center, a boom support system, a positioning device and a guide positioner, etc.

[0032] BIM technology is a data-driven tool applied to engineering design, construction, and management. It integrates data and information models of buildings and applies them to all stages of the construction process. The information contained in a BIM model includes geometric information such as spatial dimensions, as well as non-geometric information such as component types, design parameters, and construction data.

[0033] This invention achieves precise on-site positioning of the pile cutting machine through a positioning device. By guiding the positioning device with the BIM models of the pile cutting machine and the pile head, this invention completes the input of geometric and non-geometric data for the cast-in-place concrete pile. Through the guiding positioning device, this invention integrates, analyzes, and guides the positioning of the actual positioning data of the cast-in-place concrete pile and the BIM data of the pile cutting machine. This invention realizes intelligent guidance and positioning of the pile cutting machine, which is of great significance for improving construction quality and achieving digital and intelligent construction and management.

[0036] In one embodiment of the BIM-based intelligent guidance and positioning system for pile cutting machines of the present invention, the wireless transmission device is used to acquire the pile location BIM model and the pile cutting machine BIM model on site and import them into the guidance and positioning device.

[0037] The data processing chip is used to read the pile location BIM model and the pile cutting machine BIM model, and based on the pile location BIM model and the pile cutting machine BIM model, the data processing chip calculates the movement guide route of the pile cutting machine and the preset position of the pile head and displays it on the display screen; when the pile cutting machine moves to the vicinity of the preset position of the pile head according to the movement guide route, the position of the annular pile cutting head is aligned with the preset position of the pile head based on the position information of the annular pile cutting head.

[0038] In one embodiment of the BIM-based intelligent guidance and positioning system for pile cutting machines of the present invention, the positioning chip is used to collect the planar coordinates in the position information of the annular pile cutting head, and the image measuring instrument is used to collect the height coordinates of the annular pile cutting head in the position information.

[0039] In one embodiment of the BIM-based intelligent guidance and positioning system for pile cutting machines of the present invention, the number of image measuring instruments is three, such as... Figure 1 and 4 As shown, the three image measuring instruments are arranged at 90-degree intervals.

[0040] like Figure 1 and 4 As shown, in one embodiment of the BIM-based intelligent guidance and positioning system for pile cutting machines of the present invention, the number of positioning chips is three, wherein each positioning chip is respectively set on the annular pile cutting head corresponding to the location of an image measuring instrument.

[0041] like Figure 4 As shown, in one embodiment of the BIM-based intelligent guidance and positioning system for pile cutting machines of the present invention,

[0042] The coordinates of the known preset position of the pile head are (x, y, z);

[0043] The coordinates of the first positioning chip are A(x,y1,z1), and the coordinates of the stub at the front of the first positioning chip are a(x,y2,z). Among them, x and y1 of A(x,y1,z1) are acquired by the first positioning chip, and z1 of A(x,y1,z1) is acquired by the image measuring instrument at the position of the first positioning chip.

[0044] The coordinates of the second positioning chip are B(x,y4,z1), and the coordinates of the stub at the front of the second positioning chip are b(x,y3,z). Among them, x and y4 of B(x,y4,z1) are acquired by the second positioning chip, and z1 of B(x,y4,z1) is acquired by the image measuring instrument at the position of the second positioning chip.

[0045] The coordinates of the third positioning chip are C(x1,y,z1), where x1 and y of C(x1,y,z1) are acquired by the third positioning chip, and z1 of C(x1,y,z1) is acquired by the image measuring instrument at the position of the third positioning chip.

[0046] like Figure 4 As shown in one embodiment of the BIM-based intelligent guidance and positioning system for pile cutting machines of the present invention, the data processing chip is used to indicate that if the planar position is X+R=X1, Y+R=Y1, and the height position is Z=Z1, then the position of the annular pile cutting head is aligned with the preset position of the pile head.

[0047] In one embodiment of the BIM-based intelligent guidance and positioning system for pile cutters of the present invention, the data processing chip is further used to evaluate the pressure value applied by the pile cutter based on the parameter value of the pile strength in the pile location BIM model, so as to obtain the evaluated pressure value, and control the pile cutter to work based on the evaluated pressure value.

[0048] Here, the present invention uses the construction parameter values ​​attached to the BIM model of the pile head to intelligently analyze and evaluate the pressure that the pile cutter needs to apply during operation, providing stronger data support for the construction of the pile cutter.

[0049] Specifically, before the start of pile cutting at the construction site, the on-site pile location and the pile cutting machine BIM model can be wirelessly imported into the guide locator. Simultaneously, the actual positioning data of the pile cutting machine is checked to ensure the correct display of the positioning data and model data. Construction personnel select the concrete pile model component to be operated on the guide locator's touchscreen. After clicking "OK," the guide locator will display the guide route and distance for both the pile cutting machine's location and the preset position of the pile head. Based on the guide locator's prompts, the construction personnel can drive the pile cutting machine to the vicinity of the preset position of the pile head. The guide locator will then compare the spatial position of the semi-circular hydraulic pile cutting system's ring-shaped pile head with the preset position of the pile head. The operator can then fine-tune the horizontal distance until positioning is complete. Next, the guide locator will display parameters such as pile strength and provide a reference value for the pile cutting machine's construction pressure. After the operator selects the pressure value, the pile cutting machine will begin operation.

[0050] This invention combines the BIM model of concrete cast-in-place pile design with the actual positioning data of the concrete cast-in-place pile. Before pile cutting, a guide locator is used to assist construction personnel in spatially positioning the pile location. Then, the positioning device corrects the horizontal displacement of the pile cutter. At the same time, the system uses engineering values ​​contained in the BIM model, such as the pile strength, to evaluate the pressure value that the pile cutter needs to apply, thereby achieving horizontal cutting of the pile head. This ensures the quality of pile cutting, reduces manual input, lowers construction safety risks, and improves the level of digital and intelligent construction.
