Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a piling device for steel sheet pile construction in a foundation pit. Background Art

[0002] When the steel sheet pile is clamped by the pile driver's chuck, the telescopic cylinder drives the pressing plate to press the steel sheet pile against the tooth plate. At this time, both sides of the steel sheet pile are fully in contact with the tooth plate or pressing plate, allowing the pile driver to effectively complete the piling operation under different foundation conditions. When piling on a hard foundation, a special water jet piling method or spiral piling method is required to ensure that the pile foundation can successfully penetrate the hard geological layer. These two piling solutions require that the water outlet end of the water pipe or the bottom end of the spiral drill rod sleeve be welded to the bottom end of the steel sheet pile during operation. This allows the water outlet end of the water pipe or the bottom end of the spiral drill rod sleeve to move downward synchronously with the steel sheet pile, thereby assisting in piling and improving piling efficiency.

[0003] At the same time, the presence of the water outlet pipe or auger sleeve also prevents the pressure plate in the chuck from fully fitting with the bottom of the steel sheet pile, thereby affecting the clamping force and pile planting efficiency. To address this issue, multiple elastic, retractable sliders are installed on the side of the pressure plate close to the steel sheet pile to ensure that the pressure plate can still maintain effective contact with the steel sheet pile and provide sufficient clamping force. However, after clamping the water pipe or auger sleeve, the multiple retractable sliders cannot self-lock and may slip. Moreover, as the pile driver chuck frequently operates on the steel sheet pile: clamping the transplanted pile, releasing the clamping, and moving it upward, the sliders also frequently undergo compression and reset processes. This repetitive working mode, after long-term operation, may cause the elastic parts of the sliders to lose their elasticity due to fatigue, resulting in an inability to reset, ultimately affecting the normal operation of the pile planting system. Summary of the Invention

[0004] The present application proposes a foundation pit steel sheet pile construction piling equipment, which has the ability to form a corresponding clamping shape according to the clamping requirements, so that the adjusting plate can achieve self-locking and resetting in the process of clamping the water pipe or the spiral drill rod sleeve, and then in the process of achieving effective clamping of the steel sheet pile, the adjusting plate does not need to be frequently compressed and unlocked, avoiding problems such as tilting and deformation of the steel sheet pile during the installation process, ensuring that the steel sheet pile always maintains a stable and accurate installation state during the pile planting process, and improving the pile planting efficiency and pile planting quality. It is used to solve the problem that when the steel sheet pile is planted by a pile driver, the steel sheet pile clamping structure in the chuck cannot maintain effective clamping with the steel sheet pile due to different geological environments, thereby affecting the pile planting efficiency and pile planting quality.

[0007] Furthermore, an adjustment slot is provided on one side of the pressing plate close to the tooth plate and is slidably connected to the adjustment slide column. An installation slot adapted to the pawl is provided on the inner wall of the adjustment slot to provide a movable space for the pawl.

[0008] Furthermore, an elastic member is rotatably mounted on one end of the adjusting slide column close to the adjusting slot, and an end of the elastic member away from the adjusting slide column is fixedly connected to the inner wall of the adjusting slot for assisting the resetting of the adjusting plate and the adjusting slide column.

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0016] Example 1, see Figures 1 to 6 When the lifting mechanism is lifted up, the guide ring 2 and the chuck 3 are rotated to move upward, and the main hydraulic cylinder 4 is used to reliably lift the pile.

[0017] See also Figures 2 to 4 , the telescopic end of the master hydraulic cylinder 4 is fixedly installed with a mounting plate 401, and a pressing plate 5 is fixedly installed on the side of the mounting plate 401 away from the master hydraulic cylinder 4 by bolts. A plurality of adjusting plates 7 are symmetrically slidably installed on the side of the pressing plate 5 away from the master hydraulic cylinder 4, and a fixing plate 701 is fixedly installed at the center of the side of the pressing plate 5 close to the tooth plate 6. Two adjusting slide posts 8 are symmetrically rotatably installed on the side of the adjusting plate 7 away from the tooth plate 6. An adjusting slot 13 is provided on the side of the pressing plate 5 close to the tooth plate 6 to be slidably connected with the adjusting slide post 8. An elastic member 15 is rotatably installed on the end of the adjusting slide post 8 close to the adjusting slot 13, and the end of the elastic member 15 away from the adjusting slide post 8 is fixedly connected to the inner wall of the adjusting slot 13. The elastic member 15 is used to support the adjusting plate 7 through the adjusting slide post 8. When the water jet pile planting method or the spiral pile planting method is adopted, the pressing plate 5, the fixed plate 701 and the multiple adjusting plates 7 are driven to move by the telescopic end of the main hydraulic cylinder 4, so that the fixed plate 701 is pressed on the surface of the water pipe or the spiral drill rod sleeve, and the multiple adjusting plates 7 are also compressed according to the actual situation. Under the action of the elastic force of the elastic member 15, the multiple adjusting plates 7 are all fitted with the water pipe or the spiral drill rod sleeve or the steel sheet pile, forming an effective clamping of the steel sheet pile, so as to prevent the steel sheet pile from being unevenly stressed due to the inability to fully fit when the steel sheet pile is clamped by the main hydraulic cylinder 4, the pressing plate 5 and the tooth plate 6, thereby avoiding the problems of tilting, deformation and the like of the steel sheet pile during the installation process, ensuring that the steel sheet pile always maintains a stable and accurate installation state during the pile planting process, thereby improving the pile planting efficiency and pile planting quality.

[0018] After the multiple adjustment plates 7 are fully pressed to the longest stroke, the side of the adjustment plate 7 close to the tooth plate 6 is on the same horizontal plane as the fixed plate 701. During the pile planting process, whether the water jet pile planting method or the spiral pile planting method is used, the water pipe or the spiral drill rod sleeve needs to be welded to the central axis of the steel sheet pile so that the auxiliary force on both ends of the steel sheet pile is the same to prevent the steel sheet pile from tilting and shifting. Therefore, the fixed plate 701 is used to fit the diameter of the water pipe or the spiral drill rod sleeve, so it does not need to be telescoped.

[0019] See also Figures 4 to 6 , a straight slide groove 10 and an oblique slide groove 11 are provided on the outer side of the adjustment slide column 8, and the head and tail ends of the straight slide groove 10 are respectively connected to the head end or tail end of the adjacent oblique slide groove 11, and a plurality of lock holes 12 are provided on the inner bottom wall of the oblique slide groove 11, and the plurality of lock holes 12 are distributed in an array along the inner curved surface direction of the oblique slide groove 11, and a mounting groove 14 is provided on the inner wall of the adjustment slide groove 13, and a pawl 9 adapted to the lock hole 12 is fixedly installed inside the mounting groove 14. In the initial state, under the action of the elastic force of the elastic member 15, the pawl 9 is placed close to the adjustment slide column 8 and pressed. One end of the plate 5, and the bottom end of the pawl 9 is placed at the connection point of the straight slide groove 10 and the lock hole 12. When the adjusting plate 7 is squeezed and slides in the direction of the pressing plate 5, the adjusting plate 7 drives the adjusting slide column 8 to slide synchronously, so that the bottom end of the pawl 9 slides into the inclined slide groove 11 and slides through several lock holes 12. When the adjusting plate 7 cannot slide, it is stuck in the corresponding lock hole 12, and then the adjusting plate 7 is locked in position by the adjusting slide column 8, so that multiple adjusting plates 7 form a shape that is compatible with the water pipe or the spiral drill rod sleeve to effectively clamp the steel sheet pile. When the water jet pile driving method or the spiral pile driving method is used for construction, the multiple adjustment plates 7 and the elastic member 15 will not be compressed and reset frequently, thereby preventing the elastic member 15 from generating plastic deformation and cracks due to frequent compression and reset, which affects the service life of the elastic member 15. In addition, the fitting shape formed by the multiple adjustment plates 7 can also limit and guide the water pipe during the pile driving process, prevent the water pipe from tilting and affecting the water pressure, and ensure the quality level of the auxiliary pile driving of the water jet in the process of the pile driving machine body 1. After the current steel sheet pile is planted, the main hydraulic cylinder 4 is used to The telescopic end drives the pressing plate 5 and the adjusting plate 7 to move toward the tooth plate 6 until all the elastic members 15 are fully compressed. At this time, the pawl 9 gradually slides inside the inclined slide groove 11 to the connection point between the inclined slide groove 11 and the straight slide groove 10 near one end of the tooth plate 6, and is no longer engaged with the lock hole 12. Then, the pressing plate 5 is driven to slide in the opposite direction by the main hydraulic cylinder 4. Under the action of the elastic force of the elastic member 15, the adjusting plate 7 and the adjusting slide column 8 slide toward the tooth plate 6, and the pawl 9 also slides and resets inside the straight slide groove 10 to cope with the planting of the next steel sheet pile.

[0020] Since the pawl 9 has a certain elasticity when sliding through multiple lock holes 12, so that the bottom end of the pawl 9 can slide out of the current lock hole 12 and slide into the next lock hole 12, the depth of the straight slide groove 10 is greater than the depth of the inclined slide groove 11, so that the pawl 9 will not get stuck when sliding into the straight slide groove 10 and resetting through the straight slide groove 10.

[0021] Example 2, based on Example 1, please refer to Figure 4 , a plurality of auxiliary hydraulic cylinders 16 are fixedly installed inside the end of the pressing plate 5 close to the main hydraulic cylinder 4, and the plurality of auxiliary hydraulic cylinders 16 are respectively adapted to the corresponding adjusting slide 8, and the end of the auxiliary hydraulic cylinder 16 close to the adjusting plate 7 is slidably connected to the piston rod 17, and the piston rod 17 is sleeved inside the elastic member 15, and a piston is fixedly installed on the end of the piston rod 17 close to the auxiliary hydraulic cylinder 16, and the piston is slidably installed inside the auxiliary hydraulic cylinder 16, and the end of the piston rod 17 away from the auxiliary hydraulic cylinder 16 is fixedly connected to the adjusting slide 8. In the initial state, the piston rod 17 is completely placed inside the elastic member 15. As the fixed plate 701 presses on the water pipe or auger After the outside of the rod sleeve, each adjusting plate 7 is also compressed. When the adjusting plate 7 slides, it drives the piston rod 17 to slide in the direction of the auxiliary hydraulic cylinder 16. When the adjusting plate 7 cannot continue to slide under the limiting action of the water pipe or the auger rod sleeve, hydraulic medium is pumped into the rodless chamber of the auxiliary hydraulic cylinder 16 (that is, the inner chamber of the auxiliary hydraulic cylinder 16 close to one end of the main hydraulic cylinder 4), so that the piston rod 17 presses the adjusting slide column 8 under the action of the hydraulic medium, thereby increasing the clamping force of the adjusting plate 7 on the steel sheet pile, avoiding the adjusting plate 7 from slipping during the steel sheet pile planting process due to insufficient elastic force of the elastic member 15, and further improving the force uniformity of the steel sheet pile.

[0022] Working principle: When the steel sheet pile is normally planted by the pile driver body 1, a tooth plate 6 is fixedly mounted on the mounting plate 401 by means of a screw, and the bottom end of the steel sheet pile is placed inside the guide ring 2 by means of a lifting device. After the steel sheet pile is engaged with the adjacent steel sheet pile, the mounting plate 401 and the corresponding tooth plate 6 are driven by the telescopic end of the main hydraulic cylinder 4 to press the steel sheet pile onto the tooth plate 6. Subsequently, the guide ring 2, the chuck 3 and the transplanted pile under the steel sheet pile are driven by the vertical jacking oil cylinder on the pile driver body 1. After the vertical jacking oil cylinder reaches the maximum stroke, the main hydraulic cylinder 4 releases the clamping of the steel sheet pile, and under the action of the vertical jacking oil cylinder, it moves upward along with the guide ring 2 and the chuck 3 to re-clamp the steel sheet pile for planting. When the water jet piling method or the spiral piling method is used to plant piles, the mounting plate 401 is fixedly connected to the pressing plate 5 by bolts. In the initial state, under the action of the elastic force of the elastic member 15, the pawl 9 is placed on the end of the adjusting slide column 8 close to the pressing plate 5, and the pressing plate 5, the fixing plate 701 and the multiple adjusting plates 7 are driven to move by the telescopic end of the main hydraulic cylinder 4, so that the fixing plate 701 is pressed on the surface of the water pipe or the spiral drill rod sleeve. When the adjusting plate 7 is squeezed and slides in the direction of the pressing plate 5, the adjusting plate 7 drives the adjusting slide column 8 to slide synchronously, so that the bottom end of the pawl 9 slides into the inclined slide groove 11 and slides through several locking holes 12. When the adjusting plate 7 cannot slide, it is stuck in the corresponding locking hole 12, and then the adjusting plate 7 is locked in position by the adjusting slide column 8, so that the multiple adjusting plates 7 form a shape that is compatible with the water pipe or spiral drill rod sleeve. , forming an effective clamping of the steel sheet piles, so as to prevent the steel sheet piles from being unevenly stressed due to the inability to fully fit when the steel sheet piles are clamped by the main hydraulic cylinder 4, the pressing plate 5 and the tooth plate 6, thereby avoiding problems such as tilting and deformation of the steel sheet piles during the installation process, ensuring that the steel sheet piles always maintain a stable and accurate installation state during the pile planting process, thereby improving the pile planting efficiency and pile planting quality, and then pumping hydraulic medium into the rodless cavity of the auxiliary hydraulic cylinder 16, so that the piston rod 17 presses the adjusting slide column 8 under the action of the hydraulic medium, thereby improving the clamping force of the adjusting plate 7 on the steel sheet piles, and at the same time, when the water jet pile planting method or the spiral pile planting method is used for construction, multiple adjusting plates 7 and elastic parts 15 will not be frequently compressed and reset, thereby preventing the elastic part 15 from generating plastic deformation and cracks due to frequent compression and reset, which affects the service life of the elastic part 15; The fitting shape formed by the multiple adjustment plates 7 can also limit and guide the water pipe during the pile planting process, prevent the water pipe from tilting and affecting the water outlet pressure, and ensure the quality level of the auxiliary pile planting of the water jet during the pile planting process of the pile driver body 1. After the current steel sheet pile is planted, the hydraulic medium is no longer pumped into the rodless chamber of the auxiliary hydraulic cylinder 16, and the pressure of the piston rod 17 on the adjusting slide column 8 is released. The pressing plate 5 and the adjusting plate 7 are driven to move toward the tooth plate 6 by the telescopic end of the main hydraulic cylinder 4 until all the elastic members 15 are fully compressed. At this time, the pawl 9 gradually slides inside the inclined slide groove 11 to the connection between the inclined slide groove 11 and the straight slide groove 10 near one end of the tooth plate 6, and is no longer engaged with the lock hole 12. Then, the pressing plate 5 is driven by the main hydraulic cylinder 4 to slide in the opposite direction. Under the action of the elastic force of the elastic member 15, the adjusting plate 7 and the adjusting slide column 8 slide toward the tooth plate 6, and the pawl 9 also slides and resets inside the straight slide groove 10 to cope with the planting of the next steel sheet pile.
