Description

Technical Field

[0001] The present invention relates to the technical field of engineering machinery, and more particularly to a pile driver. Background Art

[0002] The static pressure pile driver is a mechanized breach plugging construction equipment that can replace manual construction. When plugging a breach, it uses a unique static pressure principle (grasping several piles that have been pressed into the ground, using the resistance of the pull-out as a reaction force to push in the next pile) to complete the pile driving.

[0003] However, the static pile driver can only move on piles, so it needs to be placed in the designated position by a crane with the cooperation of construction workers during construction. In addition, since there are no completed piles available at the beginning of the project, it is usually necessary to equip a base that provides reaction force to complete the initial pressing of reaction piles. After several piles are pressed in, the static pile driver can be detached from the base and move on the piles. Therefore, the movement of the static pile driver is restricted by the reaction piles, making construction inconvenient.

[0035] The embodiment of the invention discloses a pile driver, which can drive piles on shore and on water and can quickly complete the sealing operation of dike breach.

[0036] 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.

[0037] See also Figure 1 and Figure 2 , Figure 1 A schematic structural diagram of a pile driver according to a specific embodiment of the present invention; Figure 2 for Figure 1 Schematic diagram of the structure of the clamping device.

[0038] In one embodiment, the pile driver provided by the present invention includes a platform 1, a pile driving device 2, a walking device 4 and a clamping device 3. The platform 1 is used to install the pile driving device 2, the walking device 4 and the clamping device 3. The pile driving device 2 is connected to the top of the platform 1, and the walking device 4 and the clamping device 3 are respectively connected to the bottom of the platform 1. The pile driving device 2 includes a pile driver 21 and a pressure device 22. The pile driver 21 is used to install the pile 01. The pressure device 22 is connected to the pile driver 21 to provide a force to the pile driver 21 for pile driving. The walking device 4 is used to walk on the ground. The clamping device 3 includes a fixed clamp 31, a sliding clamp 32 and a clamping drive component 33. The fixed clamp 31 and the sliding clamp 32 are both used to clamp the pile wall. The fixed clamp 31 is fixedly connected to the platform 1, the sliding clamp 32 is slidably connected to the platform 1, and the clamping drive component 33 is connected to the sliding clamp 32 to drive the sliding clamp 32 to slide along the platform 1. Of course, the sliding movement between the sliding clamp 32 and the platform 1 is a relative movement. When the sliding clamp 32 and the pile wall are fixed, the relative sliding movement between the sliding clamp 32 and the platform 1 is manifested as the walking of the platform 1.

[0039] By using the pile driver provided by the present invention, when a breach occurs in the dike, the sealing of the breach is divided into two stages: onshore construction and on-water construction. During onshore construction, the pile driver moves to the breach position by itself through the walking device 4. To prevent the breach from expanding, piles are first driven into the dam body adjacent to the breach. The walking device 4 moves to a preset position, and the pile 01 is installed on the pile driver 21, and then a pressure is applied to the pile 01 through the pressure device 22, so that the pile is quickly formed. Repeat the above steps to drive several piles 01 into the dike in turn to form a pile wall, so that the dike is reinforced, and at the same time, a basic platform for the pile driver to construct on the water is provided. When a sufficiently long pile wall is formed on the shore, on-water construction can be carried out. Through the cooperation of the fixed clamp 31 and the sliding clamp 32, the pile driver is fixed on the pile wall for construction and moves back and forth. When walking, the fixed clamp 31 is released, the sliding clamp 32 clamps the pile wall, and the clamping driving component 33 drives the sliding clamp 32 to slide along the platform 1, so that the platform 1 moves relatively to the next piling position, and then the sliding clamp 32 can be released, the fixed clamp 31 clamps the end wall, and the clamping driving component 33 drives the sliding clamp 32 to reset. After the platform 1 moves to the piling position, the piling device 2 can piling through the above steps.

[0040] In summary, the pile driver provided in this application can be used for construction both on the ground and on the water, and is therefore convenient for dike breach sealing construction. It can quickly complete the dike breach sealing operation, ensure the life safety of construction and rescue personnel, and reduce the loss of life and property of people in the flood discharge area.

[0041] In one embodiment, the pile driver 21 of the pile driving device 2 can adopt a clamping structure, that is, the pile 01 is clamped by relative clamping plates. The pile driver 21 can also adopt other structures in the prior art that can fix the pile 01 as needed. In one embodiment, the pressure device 22 includes a winch and a steel wire rope matched with the winch. The winch drives the steel wire rope to rise or fall. The pile driver 21 is fixedly connected to the steel wire rope. The winch drives the steel wire rope to move, and the steel wire rope drives the pile driver 21 to move and form a downward impact force, thereby forming a pile.

[0042] In one embodiment, the pile driving device 2 also includes a drill mast 23 and a drill mast telescopic cylinder 24. The drill mast 23 is rotatably connected to the platform 1, and the pile driver 21 is connected to the drill mast 23. One end of the drill mast telescopic cylinder 24 is rotatably connected to the platform 1, and the other end is rotatably connected to the drill mast 23 to adjust the angle between the drill mast 23 and the platform 1. The arrangement of the drill mast 23 facilitates the installation of the pile driver 21. As needed, the pressurizing device 22 may also be arranged on the drill mast 23. Specifically, the two ends of the drill mast telescopic cylinder 24 may be hinged to the platform 1 and the drill mast 23, respectively. The drill mast telescopic cylinder 24 may be a hydraulic cylinder, and may also be an air cylinder or other telescopic drive structure as needed. With the above arrangement, during the pile driving operation, the drill mast telescopic cylinder 24 pushes the drill mast 23 to rotate relative to the platform 1 until the drill mast 23 is perpendicular to the platform 1, so that the pressurizing device 22 can better exert the pressurizing effect and form piles. When the pile driver is in the transportation state, such as Figure 3 As shown, the drill mast 23 can be driven by the drill mast telescopic cylinder 24 to rotate to a certain angle relative to the platform 1, specifically parallel to the platform 1. For example, if it is rotated to a horizontal state, the vertical height of the pile driver is reduced, thereby facilitating the transportation of the pile driver. As required, the drill mast 23 can also be fixedly connected to the platform 1, and the transportation state of the pile driving device 2 is the same as the pile driving operation state.

[0043] Further, the drill mast telescopic cylinder 24 pushes the drill mast 23 to rotate until the end face of the drill mast 23 contacts the platform 1, and the drill mast 23 is perpendicular to the platform 1. That is, when the drill mast 23 is perpendicular to the platform 1, the end face of the drill mast 23 close to the platform 1 abuts against the platform 1, and the drill mast 23 is supported by the platform 1, and the vertical state is more stable. Specifically, the platform 1 includes a platform body 11 and a boss 12 connected to the platform body 11, and one end of the bottom surface of the drill mast 23 is rotatably connected to one end corresponding to the top surface of the platform body 11. When the drill mast 23 rotates to the bottom surface abuts against the top surface of the boss 12 under the drive of the drill mast telescopic cylinder 24, the drill mast 23 is perpendicular to the platform body 11.

[0044] In one embodiment, the pile driver also includes a leveling telescopic cylinder 5, one end of which is used to support the ground, and the other end is fixedly connected to the platform 1 to lift the whole machine off the ground. By setting up the leveling telescopic cylinder 5, during construction on the shore, after the traveling device 4 moves to a preset position, the leveling telescopic cylinder 5 is extended to lift the whole machine off the ground, and then the pile driving operation is carried out under the support of the leveling telescopic cylinder 5. With such a setting, the pile driving operation process is more stable. Specifically, at least four leveling telescopic cylinders 5 are set at the bottom end of the platform 1, which can not only play the role of lifting the traveling device 4 off the ground, but also can adjust the angle between the platform 1 and the ground by controlling the respective telescopic amounts, so that the platform 1 remains horizontal.

[0045] In one embodiment, the walking device 4 includes a plurality of wheels 41 and a walking drive component connected to the wheels 41 to drive the wheels 41 to rotate. The walking drive component may specifically include an engine. The wheeled walking structure is adopted, and the walking freedom on the shore is high, and the direction adjustment is convenient. According to needs, in other embodiments, the walking device 4 may also include a crawler walking structure, and walking on the shore may also be realized. The walking drive component may specifically be arranged on the platform 1.

[0046] In one embodiment, the fixed clamp 31 includes two fixed telescopic cylinders 311 arranged opposite to each other, the opposite ends of the two fixed telescopic cylinders 311 are respectively fixedly connected to the platform 1, and the opposite ends are respectively connected to the first clamps 312, and the fixed telescopic cylinders 311 are used to drive the two first clamps 312 to move toward each other to clamp the pile wall or move away from each other to loosen the pile wall. That is, a telescopic cylinder fixed to the platform 1 is used, and the two fixed telescopic cylinders 311 form a pair, the ends of the two fixed telescopic cylinders 311 that are far away, that is, the ends that are opposite to each other, are respectively fixedly connected to the platform 1, and the other ends, that is, the ends that are close to each other, are respectively connected to the first clamps 312, and the two fixed telescopic cylinders 311 are used to drive the two first clamps 312 to move toward each other or away from each other, and the two move toward each other to clamp the pile wall, and move away from each other to loosen the pile wall. That is, when clamping the pile wall, the fixed telescopic cylinder 311 extends forward to push the first clamp 312 close to the pile row wall, thereby clamping the pile wall; when loosening, the fixed telescopic cylinder 311 retracts so that the distance between the first clamps 312 on both sides exceeds the width of the pile wall. The fixed clamp 31 adopts the above arrangement, has a simple structure, and can clamp the pile wall reliably.

[0047] Furthermore, the end face of the first clamp 312 facing the pile wall is consistent with the shape of the side wall of the corresponding side of the pile wall. The first clamp 312 is in surface contact with the pile wall, so that under the same pressure, it can provide a greater clamping force than point contact and line contact, so that the clamping effect of the first clamp 312 and the pile wall is more reliable and less likely to cause damage to the pile wall.

[0048] In one embodiment, the mobile clamp 32 includes two relatively arranged mobile telescopic cylinders, the opposite ends of the two mobile telescopic cylinders are respectively connected to the platform 1 for sliding connection, and the opposite ends are respectively connected to the second clamps, and the mobile telescopic cylinders are used to drive the two second clamps to move toward each other to clamp the pile wall or move away from each other to loosen the pile wall. That is, a telescopic cylinder slidably connected to the platform 1 is used, and the two mobile telescopic cylinders are a pair, the ends of the two mobile telescopic cylinders that are far away, that is, the ends that are opposite to each other, are respectively connected to the platform 1 for sliding connection, and the other ends, that is, the ends that are close to each other, are respectively connected to the second clamps, and the two mobile telescopic cylinders are used to drive the two second clamps to move toward each other or away from each other, and the two move toward each other to clamp the pile wall, and move away from each other to loosen the pile wall. That is, when clamping the pile wall, the mobile telescopic cylinder extends forward to push the second clamps to the pile row wall, thereby clamping the pile wall; when loosening, the mobile telescopic cylinder retracts so that the distance between the second clamps on both sides exceeds the width of the pile wall, and slides forward to the next clamping position with the platform 1. The mobile clamp 32 adopts the above arrangement, has a simple structure, and is reliable in clamping the pile wall.

[0049] Furthermore, the end face of the second clamp facing the pile wall is consistent with the shape of the side wall of the corresponding side of the pile wall. The second clamp is in surface contact with the pile wall, which can provide a greater clamping force than point contact and line contact under the same pressure, so that the clamping effect of the second clamp and the pile wall is more reliable and less likely to cause damage to the pile wall.

[0050] The fixed clamp 31 and the mobile clamp 32 are not limited to the above structure. In one embodiment, the fixed clamp 31 includes two clamping plates arranged opposite to each other, racks are fixed on the two clamping plates respectively, and gears are arranged to mesh with the racks, and the gears are connected to the clamping motor. The rotation of the clamping motor drives the gears to rotate, and the rotation of the gears drives the racks to move, so that the two clamping plates move closer or farther to clamp the pile wall or release the pile wall. The mobile clamp 32 can also adopt a similar structure, which will not be described here. The specific structures of the fixed clamp 31 and the sliding clamp 32 can refer to the conventional clamping structure in the prior art, and are not specifically limited here.

[0051] In one embodiment, the clamping drive component 33 of the clamping device 3 includes a clamping telescopic cylinder, one end of which is fixedly connected to the platform 1, and the other end is fixedly connected to the sliding clamp 32. That is, the sliding clamp 32 is driven to slide relative to the platform 1 by the extension and retraction of the clamping telescopic cylinder, which has a simple structure and reliable operation. As needed, the clamping drive component 33 may also include a motor, which is connected to the sliding clamp 32 through a chain, a belt or a gear rack, so that the torque output by the motor is converted into a linear movement and transmitted to the sliding clamp 32.

[0052] On the basis of the above embodiments, a crane 6 connected to the platform 1 is further included, and the crane 6 is used to take the pile 01 and transfer it to the pile driver 21. That is, the crane 6 is integrated into the platform 1, so that the pile 01 can be taken, transferred and installed without the need to configure a separate crane during the pile driving operation. The equipment has a higher degree of integration and is more convenient to use, which further facilitates the rapid completion of the dike breach plugging operation.

[0053] Furthermore, the crane 6 includes a telescopic boom 61, and the end of the boom 61 is connected to a pile clamp 7 for clamping the pile 01. The specific structure of the crane 6 can refer to the prior art, which includes a turntable and a telescopic boom 61 connected to the turntable, and the boom 61 is rotatably connected to the turntable.

The pile clamp 7 can specifically include a clamping plate structure arranged opposite to each other, and is driven by a motor, etc., and is clamped and fixed by the clamping plates on both sides of the pile 01. Then, through the action of the crane 6, such as the rotation of the turntable and the telescopic boom 61, the pile clamp 7 is transferred to the position of the pile driver 21, and then the pile driver 21 fixes the pile 01, and the pile clamp 7 can loosen the pile 01, completing the transportation and installation of the pile 01. As required, a structure such as a manipulator may be used to achieve the taking, transportation and installation of the pile 01.

[0054] Furthermore, the pile driver further comprises a tilting telescopic cylinder 8, the pile clamp 7 is rotatably connected to the arm 61, one end of the tilting telescopic cylinder 8 is rotatably connected to the arm 61, and the other end is rotatably connected to the pile clamp 7, so as to adjust the angle between the pile clamp 7 and the arm 61. By extending and retracting the tilting telescopic cylinder 8, the angle between the pile clamp 7 and the arm 61 can be adjusted, so as to facilitate the transportation of the pile 01, and during the transportation of the pile driver, it is also convenient to fold up the pile clamp 7 to reduce the volume of the pile driver.

[0055] In the above embodiments, the drilling mast telescopic cylinder 24, the leveling telescopic cylinder 5, the clamping telescopic cylinder, and the flip telescopic cylinder 8 can be hydraulic cylinders, air cylinders, or other telescopic drive structures. When hydraulic cylinders are used, they can be matched with hydraulic systems accordingly.
