Description

Technical Field

[0001] This application relates to the field of pile driving and extraction equipment, and more particularly to a vibratory hammer device. Background Technology

[0002] A vibratory hammer is a construction auxiliary device that generates a powerful excitation force when powered on to drive a pile into the pile hole. Its working principle is to use a motor to drive a pair of eccentric wheels to rotate in opposite directions, so that the lateral centrifugal forces they generate cancel each other out, while the vertical centrifugal forces are superimposed. The high-speed rotation of the eccentric wheels causes the excitation box to vibrate vertically up and down, thereby achieving the purpose of driving or pulling piles.

[0003] The currently disclosed technology includes a vibratory hammer body, which is equipped with a vibration device and a clamping device. The vibration device includes an excitation box, four eccentric wheels disposed inside the excitation box, and an excitation motor circumferentially linked to the eccentric wheels. The eccentric wheels have a semi-circular cross-sectional shape. The output shaft of the excitation motor is keyed to an excitation gear, which meshes with the eccentric wheels to drive them to rotate. The clamping device includes an electrically driven clamp fixed to the bottom of the excitation box, used to clamp the pile for pile driving or extraction operations.

[0004] However, due to the proliferation of elevated structures such as bridges, viaducts, and utility poles in modern society, the height distance between the elevated structure and the soil foundation is relatively small during the construction of soil piles under some of these structures. Existing vibratory hammers, after clamping the pile with an electric clamp at the bottom, occupy a large vertical space with the pile and the entire vibratory hammer, making them unsuitable for the pile driving or extraction needs in confined areas and requiring improvement. Summary of the Invention

[0005] In order to reduce the vertical space occupied by the pile and the vibratory hammer, this application provides a vibratory hammer device.

[0006] The vibratory hammer device provided in this application adopts the following technical solution:

[0007] A vibratory hammer device includes a support base, a clamping mechanism for clamping and fixing a pile body, and a vibration mechanism for providing amplitude. Both the clamping mechanism and the vibration mechanism are fixed to the support base. The support base has a pile insertion hole through which the pile body passes. The clamping mechanism includes at least two sets of enclosing units, all of which are equidistantly arranged on the periphery of the pile insertion hole. The vibration mechanism has at least two sets, all of which are symmetrically arranged on the periphery of the pile insertion hole.

[0008] By adopting the above-described technical solution, the vibratory hammer device of this application, when in use, allows the pile body to be inserted through the pile insertion hole of the support base. By controlling the movement of each group of enclosing units, the enclosing units can jointly clamp and fix the pile body, facilitating the rapid fixation of the pile body to the vibratory hammer device. After installation, the pile body is partially located above the vibratory hammer device, reducing the height space occupied by the pile body and the vibratory hammer device. When supporting the pile body under elevated buildings, only the length of the pile body needs to be considered, enabling the vibratory hammer device to adapt to pile driving and extraction operations in confined areas and meet the requirements of vibratory hammer device use under specific working conditions. In addition, by setting multiple sets of vibration mechanisms to jointly drive the vibratory hammer device to vibrate, and with each set of vibration mechanisms evenly distributed around the periphery of the pile body, the resultant vibration force generated by all vibration mechanisms can be made collinear with the vertical direction of the pile body, reducing the possibility of irregular vibration during the operation of the vibratory hammer device.

[0009] Optionally, the vibration mechanism includes a vibration box and a rotary drive component fixed inside the vibration box; the vibration mechanism is set to two sets, with couplings connecting the output ends of adjacent rotary drive components of the two sets of vibration mechanisms.

[0010] By adopting the above technical solution, and by setting a coupling rod to connect the output ends of the two rotary drive components, it is beneficial to keep the two rotary drive components rotating synchronously, thereby enabling the two sets of vibration mechanisms to maintain the same frequency vibration, so that the vibratory hammer device can clamp the pile body for pile driving or pile extraction operations.

[0011] Optionally, a universal coupling is connected between the output end of the rotary drive component and the end of the coupling rod.

[0012] By adopting the above technical solution, when the vibration mechanism is fixed to the support seat and the output ends of the two rotary drive components are offset due to assembly accuracy errors, the universal coupling can smoothly connect the coupling rod to the output end of the rotary drive component, reducing the assembly difficulty of the coupling rod.

[0013] Optionally, the vibration mechanism includes two sets of intermeshing eccentric wheel assemblies, and the rotary drive component is provided in two sets. The two sets of rotary drive components are located on opposite sides of the two sets of eccentric wheel assemblies, and each rotary drive component is intermeshing with the adjacent eccentric wheel assembly.

[0014] By adopting the above technical solution, existing vibratory hammers typically employ a single vibration mechanism. To improve the vibration effect, four eccentric wheel assemblies within this single vibration mechanism are usually arranged side-by-side along the length of the mechanism. This application, by setting two vibration mechanisms, ensures that the total number of eccentric wheel assemblies is four and maintains a constant amplitude for the vibratory hammer device. Each vibration mechanism requires only two eccentric wheel assemblies, effectively reducing the length of a single vibration mechanism and further minimizing the space occupied by the vibratory hammer device. This facilitates the normal use of the vibratory hammer device even when there are obstacles outside the construction site.

[0015] Optionally, a fixing bracket is fixed between the vibration mechanism and the support base. The fixing bracket has multiple fixing holes for fixing the vibration mechanism, some of which are reserved fixing holes.

[0016] By adopting the above technical solution, the vibration mechanism can be connected to the fixing hole through the fixing hole of the fixed bracket to realize the installation and fixation of the vibration mechanism. In addition, by setting the reserved fixing hole, in some construction sites with hard soil, the construction personnel can replace the vibration mechanism with a vibration mechanism with more sets of eccentric wheel assemblies and stronger vibration amplitude, and fix the vibration mechanism to the fixed bracket through the fixing hole and the reserved fixing hole, which can facilitate the normal use of the vibratory hammer device in hard soil environment.

[0017] Optionally, the support base is provided with multiple mounting holes for connecting the fixed bracket. The mounting holes are through holes extending through both sides of the support base, and the fixed bracket is detachably fixed to the mounting holes by connecting components.

[0018] By adopting the above technical solution, the fixed bracket is detachably fixed to the mounting hole of the support seat through the connecting component. When the fixed bracket is fixed to the side of the support seat where the clamping mechanism is located, the vibration mechanism and the clamping mechanism are located on the same side of the support seat. When using the vibratory hammer device for pile extraction, the vibration mechanism is suspended and fixed by the suspension equipment, while the clamping mechanism clamps and fixes the pile. At this time, the frictional resistance from the pile body experienced by the clamping mechanism is downward, which can reduce the possibility of the enclosure unit detaching from the support seat. When using the vibratory hammer device for pile driving, by disassembling the connecting component, the vibration mechanism is moved to the side of the support seat away from the clamping mechanism and re-fixed using the connecting component. During operation, the clamping mechanism is located below the support seat, and the frictional resistance from the pile body experienced by the enclosure unit is upward, which can also reduce the possibility of the enclosure unit detaching from the support seat, thus ensuring the overall structural stability of the vibratory hammer device.

[0019] Optionally, the vibratory hammer device also includes a vibration damping mechanism, which is located on the side of the vibratory mechanism away from the fixed support. The vibration damping mechanism includes a suspension wheel, which is used to attach to the steel cable of the suspension equipment used in conjunction with the vibratory hammer device. An auxiliary wheel set is also provided on the outer side of the suspension wheel to help fix the steel cable.

[0020] By adopting the above technical solution, when using a vibratory hammer device for pile driving or pile extraction, the vibratory hammer device can be smoothly lifted by passing the steel cable of the suspension equipment through the suspension wheel. At this time, the vibration damping mechanism is located between the suspension equipment and the vibration mechanism, which can play a role in buffering and absorbing vibration, thereby improving the stability of the suspension equipment in lifting the vibratory hammer device.

[0021] Optionally, the support base has a rope hole for the steel cable to pass through.

[0022] By adopting the above technical solution, when using a vibratory device for pile extraction, if the vibratory mechanism and the clamping mechanism are both located on top of the support, the connection between the fixed bracket and the support may detach when the suspension equipment lifts the vibratory hammer device. This application addresses this by repositioning the vibratory mechanism to the side of the support away from the clamping mechanism and placing it below the support. The steel cable is wound around the bottom of the vibratory hammer device, threaded through the rope hole, passed through the support, and reconnected to the suspension equipment. This allows the vibratory hammer device to be lifted smoothly. During pile extraction, the force on the vibratory mechanism is upward, reducing the possibility of detachment between the fixed bracket and the support.

[0023] Optionally, the outer side of the suspension wheel is provided with an auxiliary wheel set for assisting in fixing the steel cable. The auxiliary wheel set includes a plurality of auxiliary wheels, all of which are symmetrically arranged on both sides of the suspension wheel, and each of the auxiliary wheels is rotatably mounted on the outer wall of the vibration damping mechanism.

[0024] By adopting the above technical solution, when the vibratory hammer device is lifted by a suspension device, the steel cable passes through the rope hole of the support seat and enters the support seat below. After passing through each auxiliary wheel on the inner side of the vibration mechanism, the suspension wheel of the vibration damping box, and each auxiliary wheel on the outer side of the vibration mechanism in sequence, the connection position between the steel cable and the vibratory hammer device can be evenly stressed, thereby further improving the stability of the vibratory hammer device during operation.

[0025] Optionally, the enclosure unit includes a connecting base fixedly disposed on the support seat, a movable jaw plate movably disposed on the connecting base, and a linear drive component for driving the movable jaw plate to move. The linear drive component is fixed to the connecting base, and the movable end of the linear drive component is fixedly connected to the movable jaw plate for pushing the movable jaw plate closer to / away from the insertion hole.

[0026] By adopting the above technical solution, after the pile passes through the insertion hole, by controlling the action of each linear drive component, all the movable jaw plates move closer to each other and clamp and fix the pile together, so as to facilitate the use of the vibratory hammer device to drive and pull the pile.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By passing the pile through the pile hole and clamping it together with the enclosure unit, the pile is partially located above the vibratory hammer device after installation. This reduces the height space occupied by the pile and the vibratory hammer device, thus enabling the vibratory hammer device to adapt to pile driving and extraction operations in narrow areas and meet the requirements of vibratory hammer device under specific working conditions.

[0029] 2. By setting up multiple sets of vibration mechanisms to drive the vibratory hammer device to vibrate together, the resultant vibration force generated by each set of vibration mechanisms is collinear with the vertical of the pile body, which can reduce the possibility of irregular vibration when the vibratory hammer device is working.

[0030] 3. By setting connecting components, the fixed bracket can be detachably fixed to the support seat. During pile extraction, the vibration mechanism and the clamping mechanism are located on the same side of the support seat, while during pile driving, the vibration mechanism and the clamping mechanism are located on opposite sides of the support seat. This reduces the possibility of the enclosure unit separating from the support seat and ensures the stability of the overall structure of the vibratory hammer device. Attached Figure Description

[0041] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0042] Example 1

[0043] This application discloses a vibratory hammer device.

[0044] Reference Figure 1 A vibratory hammer device includes a support base 1, a clamping mechanism 2 for clamping and fixing a pile body, a vibration mechanism 3 for providing amplitude, and a damping mechanism 5 for buffering and absorbing vibration. The clamping mechanism 2 and the vibration mechanism 3 are both fixed to the support base 1, and the damping mechanism 5 is fixed to the side of the vibration mechanism 3 away from the support base 1.

[0045] The support base 1 has a pile insertion hole 11 in the middle for the pile to pass through. The pile insertion hole 11 is a through hole extending through both sides of the support base 1 in the thickness direction. The clamping mechanism 2 includes at least two sets of enclosing units. In this embodiment, the specific number of enclosing units is set to three sets, and all enclosing units are equidistantly arranged on the periphery of the pile insertion hole 11. In other embodiments, the specific number of enclosing units can also be two, four, or five sets, as long as they can drive and stably clamp the pile.

[0046] Reference Figure 2 The enclosure unit includes a connecting base 21, a movable toothed plate 22, and a linear drive component. The connecting base 21 is fixed to the support base 1 by welding. Multiple reinforcing ribs 211 are provided between the connecting base 21 and the support base 1 to enhance the connection stability between the connecting base 21 and the support base 1.

[0047] Reference Figure 3 The connecting base 21 has a movable cavity 212 on the side facing the pile hole 11. The two opposite side walls of the movable cavity 212 are respectively provided with integrally formed sliding parts 213. The extension direction of the sliding parts 213 is perpendicular to the axis direction of the pile hole 11. The two opposite sides of the movable jaw plate 22 are respectively provided with limiting grooves 221. The movable jaw plate 22 can be slidably installed inside the movable cavity 212 by the cooperation of the sliding parts 213 and the limiting grooves 221. The side of the movable jaw plate 22 facing the pile hole 11 is set as an arc surface, and the inner wall of the arc surface is provided with multiple parallel inner grooves to enhance the clamping effect of the movable jaw plate 22 on the pile body.

[0048] Back Figure 2 The linear drive component is a hydraulic cylinder 23. The cylinder body of the hydraulic cylinder 23 is fixed to the side of the connecting base 21 away from the pile hole 11. The piston rod of the hydraulic cylinder 23 passes through the movable cavity 212 and is connected to the movable jaw plate 22. The piston rod of the hydraulic cylinder 23 is in the normally retracted state, so that the movable jaw plate 22 is normally located outside the pile hole 11. When the hydraulic cylinder 23 is activated, it can push the movable jaw plate 22 to move closer to the pile hole 11. Each hydraulic cylinder 23 can drive the movable jaw plates 22 to move closer to each other, so that the arc-shaped surfaces of the movable jaw plates 22 are pressed against the outer peripheral wall of the pile body, thereby clamping and fixing the pile body.

[0049] In this embodiment, by welding and fixing one set of movable jaw plates 22 of the enclosing unit to the support base 1, and making the movable jaw plates 22 partially exposed in the pile insertion hole 11, the number of hydraulic cylinders 23 used can be reduced, which is beneficial to reducing the overall volume of the vibratory hammer device and the space occupied by the vibratory hammer device. The action of the other two hydraulic cylinders 23 can also ensure that each movable jaw plate 22 stably clamps the pile body. It is understood that in other embodiments, three hydraulic cylinders 23 can also be used to control the movement of three movable jaw plates 22 respectively, and are not limited to the method provided in this embodiment.

[0050] Reference Figure 4 The vibration mechanism 3 is provided in two sets, both sets of vibration mechanism 3 are fixed to the same side of the support 1, and the two sets of vibration mechanism 3 are respectively arranged on the two side edges of the support 1. (Refer to...) Figure 4 The vibration mechanism 3 includes a vibration box 31, a rotary drive component, and multiple sets of eccentric wheel assemblies 32. A fixed bracket 4 is provided between the vibration box 31 and the support base 1. The vibration box 31, the fixed bracket 4, and the support base 1 are detachably fixed by a connecting component.

[0051] Specifically, the support base 1 has multiple mounting holes 12, which are through holes extending through both sides of the support base 1 in the thickness direction; the fixed bracket 4 has multiple fixing holes 41, and when the fixed bracket 4 is placed on the support base 1, each fixing hole 41 is directly opposite to each mounting hole 12. The bottom of the vibration box 31 has multiple threaded holes 311, and when the vibration box 31 is placed on the fixed bracket 4, each threaded hole 311 is directly opposite to each fixing hole 41; the number of connecting parts is equal to the number of threaded holes 311, and high-strength bolts are used for the connecting parts. By passing the high-strength bolts sequentially through the mounting holes 12 and fixing holes 41 and threadedly connecting them to the threaded holes 311, the vibration box 31 and the fixed bracket 4 can be firmly fixed to the support base 1.

[0052] Reference Figure 5 When the vibratory hammer device is used for pile extraction, the vibratory box 31 is fixedly connected to the support seat 1 by using high-strength bolts, and the vibratory mechanism 3 and the clamping mechanism 2 are located on the same side of the support seat 1. When the vibratory hammer device is used for pile extraction, the vibratory mechanism 3 is suspended and fixed by the suspension equipment, while the clamping mechanism 2 clamps and fixes the pile body. During operation, the frictional resistance from the pile body received by the movable jaw plate 22 is downward, which can reduce the possibility of the connecting base 21 and the support seat 1 separating.

[0053] Reference Figure 6 When the vibratory hammer device is used for pile driving, the vibration mechanism 3 is moved to the side of the support seat 1 away from the clamping mechanism 2, and the vibration box 31 is fixedly connected to the support seat 1 with high-strength bolts. During operation, the clamping mechanism 2 is located below the support seat 1, and the frictional resistance from the pile body to the movable jaw 22 is directed upward, which can also reduce the possibility of the connecting base 21 separating from the support seat 1, so as to ensure the stability of the overall structure of the vibratory hammer device.

[0054] Reference Figure 7 In this embodiment, there are two sets of eccentric wheel assemblies 32 in a set of vibration mechanisms 3. Both sets of eccentric wheel assemblies 32 are rotatably installed inside the vibration box 31. The eccentric wheel assembly 32 includes a fixedly connected eccentric wheel 321 and a transmission gear 322. The cross-sectional shape of the eccentric wheel 321 is semi-circular. The eccentric wheel 321 is rotatably connected inside the vibration box 31. The transmission gears 322 on the two eccentric wheels 321 mesh with each other for transmission.

[0055] Back Figure 4 The rotary drive components are provided in two sets, located on opposite sides of the two sets of eccentric wheel assemblies 32, with each rotary drive component arranged side-by-side with each eccentric wheel 321. (See also...) Figure 7The rotary drive component is a hydraulic motor 33. The output shaft of the hydraulic motor 33 is keyed to an excitation gear 331. Each excitation gear 331 meshes with the transmission gear 322 of the adjacent eccentric wheel 321. The two sets of hydraulic motors 33 drive the corresponding eccentric wheels 321 to rotate in opposite directions, so that the lateral centrifugal force generated by the eccentric wheels 321 cancels each other out, while the vertical centrifugal force is superimposed. The high-speed rotation of the eccentric wheels 321 enables the vibration box 31 to have a vertical up-and-down vibration amplitude.

[0056] Since the vibration mechanism 3 used in this embodiment has two eccentric wheels 321, by setting two sets of vibration mechanisms 3 so that all eccentric wheels 321 are arranged in pairs, the length of a single vibration mechanism 3 can be effectively shortened, thereby reducing the space occupied by the entire vibratory hammer device.

[0057] The spacing of the vibration box 31 along its length is smaller than the spacing of the fixed bracket 4 along its length. The fixing holes 41 partially exposed in the vibration box 31 are reserved fixing holes 41, which can be used to replace the vibration mechanism 3 with a larger number of eccentric wheels 321 and a stronger vibration amplitude in the future, so as to facilitate the normal use of the vibratory hammer device in certain hard soil environments.

[0058] Back Figure 4 A coupling 34 is provided between two adjacent hydraulic motors 33 of the two sets of vibration mechanisms 3. The output shaft of the hydraulic motor 33 passes through the vibration box 31 and is exposed on the side of the vibration box 31 near the other vibration box 31. Each coupling 34 has a universal coupling 35 at its end, and the coupling 34 is connected to the exposed end of the output shaft of the hydraulic motor 33 through the universal coupling 35. The coupling 34 is designed to keep the output shafts of the two hydraulic motors 33 rotating synchronously, thereby enabling the two sets of vibration mechanisms 3 to vibrate at the same frequency, so as to facilitate the vibratory hammer device to clamp the pile for pile driving or pile extraction operations. It is understood that the coupling 34 needs to be offset from the position directly above the pile hole 11 to reduce interference between the pile and the coupling 34.

[0059] The vibration damping mechanism 5 includes a vibration damping box 51, vibration damping rubber 52, and suspension wheels 53. The vibration damping box 51 is located on the side of the vibration box 31 away from the fixed support 4. The vibration damping box 51 includes a fixed seat 511 and a movable seat 512. The fixed seat 511 is fixedly connected to the side of the vibration box 31 away from the fixed support 4, while the movable seat 512 is movably fitted onto the outside of the fixed seat 511. Multiple vibration damping rubbers 52 are provided, all evenly distributed inside the vibration box 31, and each vibration damping rubber 52 is connected between the fixed seat 511 and the movable seat 512.

[0060] The vibration damping box 51 has a mounting port 513 on its side away from the vibration box 31, and the mounting port 513 is located in the middle of the vibration damping box 51; the suspension wheel 53 is connected to the mounting port 513 of the vibration damping box 51. The suspension wheel 53 is used to attach the steel cable of the suspension equipment used in conjunction with the vibratory hammer device. In actual construction, the vibration damping mechanism 5 is always located above the support seat 1, and the vibratory hammer device can be easily lifted after the steel cable is wrapped around both sides of the suspension wheel 53.

[0061] The implementation principle of Embodiment 1 of this application is as follows:

[0062] When the vibratory hammer device of this application is used, by inserting the pile body through the pile insertion hole 11 of the support seat 1, the movement of each hydraulic cylinder 23 can be controlled so that the movable jaw plate 22 can clamp and fix the pile body together. Since the pile body is inserted through the support seat 1 and partially located above the support seat 1, the height space occupied by the pile body and the vibratory hammer device can be reduced. When supporting the pile body under the elevated building, only the length of the pile body needs to be considered, so that the vibratory hammer device can be adapted to pile driving and pile extraction operations in narrow areas and meet the use of the vibratory hammer device under specific working conditions.

[0063] Example 2

[0064] This application discloses a vibratory hammer device.

[0065] Reference Figure 8 The vibratory hammer device disclosed in this application has the same components as in embodiment 1, and will not be described in detail here; the difference from embodiment 1 is that:

[0066] In this embodiment, an auxiliary wheel set 6 for assisting in fixing the steel cable is provided on the outer side of the suspension wheel 53. The auxiliary wheel set 6 includes a plurality of auxiliary wheels 61, all of which are evenly distributed and respectively located on both sides of the suspension wheel 53. Rotating brackets 62 are respectively mounted on both sides of the movable seat 512 in the width direction. The number of rotating brackets 62 is set to be equal to the number of auxiliary wheels 61. Each auxiliary wheel 61 is rotatably mounted on the rotating bracket 62, so that the auxiliary wheel 61 can rotate freely on the rotating bracket 62. After installation, all auxiliary wheels 61 are symmetrically arranged on both sides of the vibration damping box 51.

[0067] Reference Figure 9 In this embodiment, the specific number of auxiliary wheels 61 is set to four, and the four auxiliary wheels 61 are respectively arranged in pairs on both sides of the width direction of the vibration damping box 51; in other embodiments, the specific number of auxiliary wheels 61 can also be two, six or eight, and is not limited to the manner provided in this embodiment.

[0068] Simultaneously refer to Figure 8The support base 1 has rope holes 13, which are through holes extending through both sides of the support base 1 in the thickness direction. The rope holes 13 are provided for the steel cable of the suspension equipment to pass through. In this embodiment, the clamping mechanism 2 and the vibration mechanism 3 are normally fixed on two opposite sides of the support base 1. During pile driving operations, the clamping mechanism 2 is located below the support base 1, while the vibration mechanism 3 is located above the support base 1. The steel cable can smoothly lift the vibratory hammer device after passing through the suspension wheel 53 located at the top. When performing pile extraction, the clamping mechanism 2 is located above the support base 1, while the vibration mechanism 3 is located below the support base 1. At this time, the steel cable is passed through the rope hole 13 and enters the area below the support base 1. After passing around the two auxiliary wheels 61 inside the adjacent vibration box 31, the suspension wheel 53 of the vibration damping box 51, and the two auxiliary wheels 61 outside the adjacent vibration box 31, the vibratory hammer device can be lifted smoothly. At this time, the connection between the steel cable and the vibratory hammer device is evenly stressed. Then, the pile body is passed through the pile insertion hole 11 and clamped by the clamping mechanism 2, which can maintain good stability when the vibratory hammer device is working.

[0069] The implementation principle of Embodiment 2 of this application is as follows:

[0070] During pile extraction, the frictional resistance from the pile body experienced by the clamping mechanism 2 is downward, which can force the support seat 1 to move downward. By placing the vibration damping mechanism 5, the vibration mechanism 3, and the fixed bracket 4 below the support seat 1, the support seat 1 moves towards the vibration mechanism 3 under the action of frictional resistance, which can reduce the possibility of the connection between the support seat 1 and the fixed bracket 4, and the connection between the fixed bracket 4 and the vibration box 31, becoming detached.

[0071] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
