Description

Technical Field

[0001] The invention relates to the technical field of pile driving equipment, in particular to an information-based fully automatic low-headroom pile driving equipment. Background Art

[0002] Static pressure piles are pressed by the reaction force provided by anchor rods or counterweights. The piles are generally square or round. The piles used for foundation replacement are generally small-section piles. Their construction has the advantages of no vibration, convenient construction, short construction period, operation in a small space, and a wide range of applications. They are widely used in the renovation and reinforcement of existing urban buildings, especially historical protected buildings.

[0003] Existing buildings and historical buildings have narrow spaces, especially the clearance height is generally small, and static pile equipment must meet the low clearance construction requirements. The pile pressure force, pile length, and verticality during static pile construction are key parameters in the construction process. They need to be recorded during construction and guided by these parameters. Welding quality is the key to construction quality, and welding speed is the determining factor of pile speed.

[0004] In the past, there were two types of pile driving equipment commonly used, the upper pressure type and the holding pressure type. A Chinese utility model patent (CN 207812523U) disclosed an anchor static pressure pile construction device, which adopted the upper pressure type. The device can be assembled according to the construction site and space requirements, but when encountering low clearance, the length of the single-section pile needs to be reduced, which greatly reduces the pile driving efficiency: (CN 205804352 U) disclosed an integral pile driver, which adopted the holding pressure type, but the informationization and automation degree of the equipment was not high.

[0005] The pile driving force is generally recorded manually and converted from the data displayed on the oil pressure gauge on the oil pump. The pile driving length is generally calculated based on the number of pile driving sections and the measurement with a tape measure. The Chinese utility model patent (CN208167831U) discloses an anchor pile construction recording device that records the pile driving force and pile driving depth. However, the device collects less data and cannot provide feedback to the pile driving process through data analysis.

[0006] Verticality is usually measured by a horizontal ruler, and the verticality of the pile is adjusted manually. A Chinese utility model patent (CN 211547721U) discloses a verticality control device suitable for anchor static pressure pile construction, which can conveniently and accurately measure the verticality of the anchor static pressure pile and can perform corresponding calibration. However, the device requires manual observation and cannot be informationized.

[0007] The commonly used method for pile welding is manual welding, which needs to be carried out symmetrically, requires a large number of welders, and the site is mostly in a small space. There is a lot of smoke and dust during welding, and the construction environment is harsh, which is not good for the health and safety of welders. Summary of the invention

[0008] The purpose of the present invention is to provide an information-based fully automatic low-headroom pile driving equipment based on the above-mentioned deficiencies in the prior art. The pile driving equipment adopts a holding and pressing method (through a clamp) to drive piles, and collects the pile driving force, pile driving length and verticality data during the pile driving process through a pile driving force collection device, a pile driving length collection device and a verticality collection device, and integrates and analyzes the data through a control host, and feeds back to the oil pump and the clamp in real time, so as to realize automatic pile driving, automatic judgment of pile driving termination, and automatic adjustment of verticality (through a verticality guiding and adjusting device).

[0031] like Figure 1-9 As shown, the marks 1-22 in the figure respectively represent: jack 1, force transmission column 2, upper tray 3, lower tray 4, clamp 5, oil pump 6, pile length collection device 7, pile force collection device 8, control host 9, welding guide rail 10, verticality collection device 11, clamp 12, steel pipe 13, guide jack 14, guide clamp 15, automatic welding machine 16, pulley 17, first length collector 18, horizontal plate 19, dial 20, measuring rod 21, second length collector 22, upper section pile 23, lower section pile 24.

[0032] Example: Figures 1 to 9 As shown, this embodiment relates to an information-based fully automatic low-headroom pile driving equipment, which is mainly used for the jacking of pile bodies. In this embodiment, the pile body is a steel pipe 13, which mainly includes a pile driving system, a pile driving force collection device 8, a pile driving length collection device 7, a verticality collection device 11, a verticality guiding and adjusting device, an automatic welding device and a control host 9. The pile driving system includes a jack 1, a force transmission column 2, an upper tray 3, a lower tray 4, a clamp 5 and an oil pump 6. Both ends of the force transmission column 2 are connected to the upper tray 3 and the lower tray 4 respectively by bolts. The clamp 5 is arranged between the upper tray 3 and the lower tray 4, and the clamp 5 is used to clamp and fix the steel pipe 13. In this embodiment, the number of force transmission columns 2 is four, and the four corners of the clamp 5 are respectively penetrated by four force transmission columns 2. The lower tray 4 is connected to the anchor rod or the pile load to provide pile driving reaction force. The housing of the jack 1 is connected to the upper tray 3 by bolts, the bearing of the jack 1 is connected to the hoop 5, and the jack 1 is connected to the oil pump 6. The oil pump 6 drives the jack 1 to move up and down, so as to drive the hoop 5 to move along the length direction of the force transmission column 2, thereby achieving the purpose of pushing the steel pipe 13 downward. The pile pressure force collection device 8 is installed on the oil pump 6; the pile pressure length collection device 7 is installed on the force transmission column 2; the verticality collection device 11 is installed on the upper tray 3 and the lower tray 4; the verticality guide and adjustment device is installed on the lower tray 4, and the verticality guide and adjustment device is connected to the oil pump 6; the automatic welding device is installed on the force transmission column 2; the control host 9 is respectively connected to the oil pump 6, the pile pressure force collection device 8, the pile pressure length collection device 7 and the verticality collection device 11.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, four clamps 12 are arranged around the center of the hoop 5, and the clamps 12 are controlled by hydraulic devices, which are connected in series and are connected to the oil pump 6. The control host 9 controls the operation of the hydraulic device through the oil pump 6, thereby controlling the clamps 12 to clamp or release.

[0034] like Figure 1 , Figure 2 and Figure 7 As shown, the pile driving length collection device 7 includes a pulley 17 and a first length collector 18 mounted on the pulley 17, and the first length collector 18 is connected to the control host 9. When the pile is driven, the pulley 17 is close to the steel pipe 13 and slides with the pile driving. The first length collector 18 records the length and transmits the data to the control host 9. Specifically, the first length collector 18 contains a counter, and sensors with fixed step lengths are evenly distributed on the pulley 17. When the pulley 17 rotates, the counter records the number of sensors, and the control host 9 calculates the rotation length of the outer diameter of the pulley 17, that is, the pile driving length.

[0035] like Figure 1 and Figure 2 As shown, the pile-driving force collection device 8 is installed at the position of the pressure gauge of the oil pump 6. Since the pile-driving force collection device 8 is connected to the control host 9, the pressure of the jack 1 can be directly collected when the oil pump 6 is working.

[0036] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the verticality acquisition device 11 includes a horizontal plate 19, a dial plate 20, a measuring rod 21, and a second length collector 22 installed on the horizontal plate 19. The dial plate 20 is connected to the measuring rod 21 and the second length collector 22 respectively, and the second length collector 22 is connected to the control host 9. The horizontal plate 19 is adjusted to a horizontal state (perpendicular to the ground) by the scale on the horizontal plate 19. The measuring rod 21 is in close contact with the steel pipe 13. Since the measuring rod 21 is connected to the dial plate 20, when the pile is pressed, when the verticality of the pile changes, the measuring rod 21 will drive the dial plate 20 to rotate, and the second length collector 22 will transmit information to the control host 9, and the control host 9 calculates the verticality, and can also directly read the verticality according to the number indicated on the dial plate 20. Specifically, the second length collector 22 contains a counter, and sensors with fixed step lengths are evenly distributed on the dial 20. When the measuring rod 21 drives the dial 20 to rotate, the counter records the number of sensors, and the control host 9 calculates the rotation angle of the dial 20 and the verticality change value. In this embodiment, the number of verticality collection devices 11 is 4, 2 verticality collection devices 11 are bolted to the upper tray 3 and arranged at 90 degrees; 2 verticality collection devices 11 are bolted to the lower tray 4 and arranged at 90 degrees.

[0037] like Figure 1 , Figure 2 and Figure 6As shown, the verticality guiding and adjusting device includes four guiding jacks 14 and four guiding fixtures 15 installed on the guiding jacks 14. The guiding jacks 14 are connected to the oil pump 6, and the oil pump 6 is connected to the control host 9. When the pile is pressed, the control host 9 controls the four guiding jacks 14 to work respectively through the oil pump 6. The guiding fixture 15 is arc-shaped and matches the outer surface of the pile body, which can guide the pile and generate horizontal thrust on the pile to adjust the verticality of the pile.

[0038] In this embodiment, when connecting piles, the verticality collection device 11 connected to the upper tray 3 transmits information to the control host 9 to ensure that the verticality of the upper pile section 23 meets the requirements; the verticality collection device 11 connected to the lower tray 4 transmits information to the control host 9, the control host determines the verticality of the pile, and adjusts the verticality of the lower pile section 24 through the guide jack 14; when pressing the pile, the four verticality collection devices 11 jointly transmit the verticality information to the control host 9, and the verticality of the pile is adjusted in real time through the guide jack 14.

[0039] like Figure 1 , Figure 2 and Figure 8 As shown, the automatic welding device includes a welding track 10 and an automatic welding machine 16 installed on the welding track 10, and the welding track 10 is arranged on the force transmission column 2. When connecting piles, after the upper section pile 23 and the lower section pile 24 are aligned, the automatic welding machine 16 is installed on the welding track 10 for automatic welding.

[0040] like Figure 1 , Figure 2 and Fig. 9 As shown, the control host 9 is respectively connected with the oil pump 6, the pile driving force acquisition device 8, the pile driving length acquisition device 7 and the verticality acquisition device 11. During the pile driving process, the control host 9 controls the clamp 5 to hold the pile tightly through the oil pump 6, and controls the jack 1 to drive the pile through the oil pump 6; the data collected by the pile driving force acquisition device 8 and the pile driving length acquisition device 7 are transmitted to the control host 9, and through analysis, it is determined whether the pile driving termination condition is reached; the verticality acquisition device 11 transmits the data to the control host 9, and through analysis of the data, the control host 9 controls the guide jack 14 through the oil pump 6 to adjust the pile driving verticality.

[0041] Although the above embodiments have described in detail the concepts and embodiments of the present invention with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and changes can still be made to the present invention without departing from the scope of the claims, so they are not described one by one here.
