Description

Technical Field

[0001] This invention relates to the field of vibratory hammer technology, specifically a twelve-linkage hydraulic vibratory hammer device. Background Technology

[0002] A vibratory hammer is a device used to drive or remove various types of steel plate and pipe piles. The principle of vibratory hammer technology is that the relative motion of two eccentric gears generates up-and-down vibrations, separating the pile from the surrounding soil layer, reducing frictional resistance, and achieving the purpose of driving or removing the pile. It features strong driving force, good pile driving quality, durability, few malfunctions, ease of use, strong power supply adaptability, and low noise. The vibratory hammer is a type of inertial vibratory hammer and can be widely used in different soil types, its main function being pile driving.

[0003] In the construction of large bridges, tunnels, and other engineering projects, the vibratory driving of large steel pipe piles is very challenging. Therefore, a hydraulic vibratory hammer assembly consisting of twelve vibratory hammers is used. The twelve vibratory hammers are linked by a gearbox, which ensures that the amplitude of the eccentric blocks is consistent, resulting in synchronized vibration. This transforms several vibratory hammers into a large vibratory hammer assembly, improving the pile driving efficiency in heavy engineering projects. However, the gearboxes and vibratory hammers are usually connected by multiple bolts, and twelve vibratory hammers require twelve gearboxes for connection, making disassembly and assembly difficult, increasing installation complexity, and reducing maintenance efficiency.

[0004] To address this issue, we propose a twelve-linkage hydraulic vibratory hammer device to solve the problem of difficult disassembly and assembly, and reduced maintenance efficiency, caused by the multiple bolts connecting the vibratory hammer and gearbox. Summary of the Invention

[0005] The purpose of this invention is to provide a twelve-linkage hydraulic vibratory hammer device to solve the problem mentioned in the background art, which is that the vibratory hammer and gearbox are connected by multiple bolts, making disassembly and assembly difficult and reducing maintenance efficiency.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a twelve-linkage hydraulic vibratory hammer device, comprising twelve main beams, with secondary beams provided between adjacent main beams, the twelve main beams and secondary beams forming a ring vibration frame, a vibratory hammer body installed at the upper end of each main beam, a gearbox provided between adjacent vibratory hammer bodies, a clamp body provided at the lower end of each main beam, a linkage shaft provided at one end of each vibratory hammer body, a warning sleeve provided on the outer surface of the linkage shaft, a tensioning seat provided on the outer surface of the warning sleeve, an insert rod provided between the warning sleeve and the tensioning seat, a diaphragm coupling provided on the outer surface of the tensioning seat, a rotating ring rotatably connected to the other end of the diaphragm coupling, a linkage bevel gear provided at one end of the gearbox, the other end of the linkage bevel gear being fixedly connected to the diaphragm coupling, a rotatable ring rotatably connected at the outer end of the connection between the vibratory hammer body and the linkage shaft, a conical tooth set meshing on the inner surface of the rotatable ring, a screw provided at one end of the conical tooth set, and a pressing plate threadedly connected to the outer surface of the screw; Both ends of the inner sidewall of the main beam are hinged with telescopic rods, and the other end of the telescopic rod is hinged with a base. The telescopic rod includes several slidably connected sleeves. One end of the sleeve is provided with a spring, and the other end of the spring is fixedly connected with a protrusion. The protrusion is slidably connected to the sleeve, and the other end of the sleeve is provided with a groove that matches the protrusion. A hydraulic cylinder is fixedly connected to one end of the fixture body, a piston rod is installed at the other end of the hydraulic cylinder, a bracket is fixedly connected to the other end of the piston rod, a jaw plate is fixedly connected to the other end of the bracket, and a jaw plate is provided on the inner side of the other end of the fixture body. The jaw plate is fixedly connected to the fixture body by fastening bolts.

[0007] Furthermore, a ring-shaped vibratory frame is formed by the main beam and the secondary beam, and twelve vibratory hammer bodies are installed on the main beam, facilitating the vibratory driving of large steel pipe piles. The twelve vibratory hammer bodies are connected via a gearbox to ensure consistent amplitude. A keyless connection is achieved between the linkage shaft and the diaphragm coupling through a warning sleeve and a tensioning seat, generating a large clamping force that protects the equipment from damage and resolves the phase difference between eccentric blocks of adjacent vibratory hammers. This is existing technology and will not be elaborated upon here. The tensioning seat is aligned with the warning sleeve and inserted, limited by a rod. The rotating ring drives the screw through a conical gear set, which pushes the extrusion plate, causing the extrusion plate to press against the rotating ring, thus tightly connecting the tensioning seat and the warning sleeve, thereby fixing the gearbox. This facilitates quick disassembly and assembly of the gearbox and makes maintenance easier. The main beam and secondary beam are then installed... After assembly, the ring-shaped vibration frame is erected. The upper ends of the bases on both sides of the ground are moved to make the bases contact the ground, which in turn causes the telescopic rod to extend and fix. The sleeve inside the telescopic rod slides out continuously, and through spring one, it pushes out the protrusion, causing the protrusion to engage in the groove of another sleeve, thus supporting the ring-shaped vibration frame and enhancing its stability. This facilitates improved installation stability. The second toothed plate is fixedly connected to the main body of the clamp with fastening bolts, making it easy to disassemble and replace. The bracket supports both ends of the first toothed plate, reducing the possibility of deformation when fixing different pipe piles. By activating the hydraulic cylinder, the hydraulic cylinder pushes the piston rod, which moves the first toothed plate through the bracket, causing the first and second toothed plates to clamp the upper side wall of the pipe pile. This facilitates the replacement of the second toothed plate, enhances the stability of the first toothed plate, and prevents deformation after prolonged use.

[0008] Preferably, the other end of the gearbox is provided with a synchronous bevel gear, and a universal coupling is provided between adjacent synchronous bevel gears.

[0009] Furthermore, gearboxes, synchronous bevel gears, and universal couplings are all existing technologies and will not be elaborated upon here.

[0010] Preferably, both ends of the ring are provided with latches between them and the vibratory hammer body, one end of the screw is rotatably connected to the vibratory hammer body, and the extrusion plate is slidably connected to the vibratory hammer body.

[0011] Furthermore, the locking mechanism secures the ring, preventing it from rotating after prolonged use and causing the extrusion plate to loosen.

[0012] Preferably, the other end of the extrusion plate is provided with an inclination angle, and the outer end of the rotating ring is provided with a groove that matches the extrusion plate.

[0013] Furthermore, the extrusion plate is set with an inclination angle to facilitate changing the direction of the force, pushing the tension seat to clamp tightly with the warning sleeve, and limiting the rotation ring through the slot on the rotation ring.

[0014] Preferably, the linkage bevel gear meshes with the synchronous bevel gear, and a cover plate is hinged to the outer end of the ring.

[0015] Furthermore, a cover plate is installed at the front end of the ring to minimize the impact of external factors.

[0016] Preferably, both sides of the outer end of the base are rotatably connected to knobs, one end of each knob is fixedly connected to a gear, and both ends of the gear are meshed with racks.

[0017] Furthermore, by rotating the knob, the knob drives gear one to rotate, and gear one drives the racks on both sides to move in opposite directions, so that the racks are inserted into the main beam, thereby limiting the base. Rotating the knob in the opposite direction cancels the limitation on the base.

[0018] Preferably, the main beam is snapped into the base, and a slot is provided at the connection between the main beam and the base.

[0019] Preferably, the piston rod and the bracket are slidably connected to the fixture body, and the first jaw plate and the second jaw plate are arranged opposite to each other.

[0020] Furthermore, the main body of the clamp plays a limiting role for both the piston rod and the bracket. The opposing arrangement of jaw plate one and jaw plate two facilitates the clamping of the upper side wall of the pipe pile.

[0021] Preferably, a pad is provided between the clamp body and the fastening bolt.

[0022] Compared with the prior art, the beneficial effects achieved by the present invention are: First, this invention uses a ring-shaped vibration frame composed of a main beam and a secondary beam to mount twelve vibratory hammer bodies on the main beam, facilitating the vibratory driving of large steel pipe piles. The twelve vibratory hammer bodies are connected via a gearbox to ensure consistent amplitude. A keyless connection is achieved between the linkage shaft and the diaphragm coupling through a warning sleeve and a tensioning seat, protecting the equipment from damage and resolving the phase difference between eccentric blocks of adjacent vibratory hammers. The above is existing technology and will not be elaborated upon here. The tensioning seat is inserted into the warning sleeve, limited by a rod, and rotated around the ring. The rotating ring drives the screw to rotate via a conical gear set, which pushes the extrusion plate, causing the extrusion plate to press against the rotating ring, thus tightly connecting the tensioning seat and the warning sleeve, thereby fixing the gearbox and facilitating quick disassembly and maintenance of the gearbox.

[0023] Secondly, in this invention, after the main beam and the secondary beam are installed, the ring-shaped vibration frame composed of them is erected. The upper ends of the bases on both sides of the ground are moved to make the bases contact the ground, which drives the telescopic rod to extend and fix. The sleeve inside the telescopic rod slides out continuously, and the spring pushes out the protrusion, so that the protrusion is locked into the groove of the other sleeve, thereby achieving the function of supporting the ring-shaped vibration frame and enhancing stability, so as to facilitate the improvement of installation stability. By fixing the toothed plate to the clamp body with fastening bolts, it is easy to disassemble and replace.

[0024] Third, the present invention supports both ends of the toothed plate by means of a bracket, reducing the possibility of deformation when fixing different pipe piles. By activating the hydraulic cylinder, the hydraulic cylinder pushes the piston rod, and the piston rod drives the toothed plate to move through the bracket, so that the toothed plate and the toothed plate clamp the upper side wall of the pipe pile, thereby facilitating the replacement of the toothed plate and strengthening the stability of the toothed plate, and avoiding deformation after long-term use.

Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] The following is a specific implementation method of a twelve-linkage hydraulic vibratory hammer device.

[0029] Please see Figure 1-3 A twelve-linkage hydraulic vibratory hammer device includes twelve main beams 1, with secondary beams 2 between adjacent main beams 1, forming a ring-shaped vibratory frame. A vibratory hammer body 3 is mounted on the upper end of each main beam 1, and a gearbox 4 is provided between adjacent vibratory hammer bodies 3. A clamping body 5 is provided at the lower end of each main beam 1. A linkage shaft 301 is provided at one end of each vibratory hammer body 3. A warning sleeve 302 is provided on the outer surface of the linkage shaft 301, and a tensioning seat 303 is provided on the outer surface of the warning sleeve 302. A rod 31 is provided between the warning sleeve 302 and the tensioning seat 303. 3. The outer surface of the tensioning seat 303 is provided with a diaphragm coupling 304. The other end of the diaphragm coupling 304 is rotatably connected to a rotating ring 305. One end of the gearbox 4 is provided with a linkage bevel gear 306. The other end of the linkage bevel gear 306 is fixedly connected to the diaphragm coupling 304. The outer end of the connection between the vibrating hammer body 3 and the linkage shaft 301 is rotatably connected with a winding ring 307. The inner surface of the winding ring 307 is meshed with a conical tooth set 308. One end of the conical tooth set 308 is provided with a screw 309. The outer surface of the screw 309 is threadedly connected to a pressing plate 310. Please see Figure 4-6 Both ends of the inner sidewall of the main beam 1 are hinged with telescopic rods 101, and the other end of the telescopic rod 101 is hinged with a base 102. The telescopic rod 101 includes several slidably connected sleeves 1010. One end of the sleeve 1010 is provided with a spring 1011, and the other end of the spring 1011 is fixedly connected with a protrusion 1012. The protrusion 1012 is slidably connected with the sleeve 1010, and the other end of the sleeve 1010 is provided with a groove that matches the protrusion 1012. Please see Figure 7 A hydraulic cylinder 501 is fixedly connected to one end of the fixture body 5. A piston rod 502 is installed at the other end of the hydraulic cylinder 501. A bracket 503 is fixedly connected to the other end of the piston rod 502. A toothed plate 504 is fixedly connected to the other end of the bracket 503. A toothed plate 505 is provided on the inner side of the other end of the fixture body 5. The toothed plate 505 is fixedly connected to the fixture body 5 by fastening bolts.

[0030] Through the above technical solution, a ring-shaped vibration frame is formed by the main beam 1 and the secondary beam 2, and twelve vibratory hammer bodies 3 are installed on the main beam 1, thus facilitating the vibratory driving of large steel pipe piles. The twelve vibratory hammer bodies 3 are connected by a gearbox 4 to ensure consistent amplitude. A large clamping force is generated between the linkage shaft 301 and the diaphragm coupling 304 through the warning sleeve 302 and the tensioning seat 303, achieving a keyless connection. This protects the equipment from damage and solves the phase difference of eccentric blocks between adjacent vibratory hammers. The above is existing technology and will not be elaborated upon here. The seat 303 is inserted into the warning sleeve 302 and limited by the insertion rod 313. The rotating ring 307, which has toothed grooves on its inner side, drives the screw 309 to rotate through the conical tooth set 308. The screw 309 pushes the extrusion plate 310, causing the extrusion plate 310 to press the rotating ring 305, thereby tightly connecting the tension seat 303 and the warning sleeve 302, thus fixing the gearbox 4. This facilitates quick disassembly and assembly of the gearbox 4 and makes maintenance easier. After the main beam 1 and the secondary beam 2 are installed, the ring vibration frame composed of them is erected. By moving the bases 102 near the ground on both sides, the bases 102 come into contact with the ground, causing the telescopic rod 101 to extend and fix. The sleeve 1010 inside the telescopic rod 101 slides out continuously, and through the spring 1011, it pushes out the protrusion 1012, causing the protrusion 1012 to engage in the groove of the other sleeve 1010, thereby limiting the telescopic rod 101 and supporting the annular vibration frame, enhancing stability, and achieving the effect of improving installation stability. This avoids the problem of difficulty in flipping the annular vibration frame after one side has been installed, and the toothed plate... The second toothed plate 505 is fixedly connected to the clamp body 5 by fastening bolts, which facilitates disassembly and replacement. The bracket 503 supports both ends of the first toothed plate 504, reducing the possibility of deformation when fixing different pipe piles. By activating the hydraulic cylinder 501, the hydraulic cylinder 501 pushes the piston rod 502. The piston rod 502 drives the first toothed plate 504 to move through the bracket 503, so that the first toothed plate 504 and the second toothed plate 505 clamp the upper side wall of the pipe pile, which facilitates the replacement of the second toothed plate 505, enhances the stability of the first toothed plate 504, and avoids deformation after long-term use.

[0031] Please refer to 2. The other end of the gearbox 4 is provided with a synchronous bevel gear, and a universal coupling is provided between adjacent synchronous bevel gears.

[0032] The gearbox 4, synchronous bevel gear and universal coupling are all existing technologies according to the above technical solutions, and will not be described in detail here.

[0033] Please see Figure 3 Both ends of the ring 307 are provided with latches 311 between them and the vibratory hammer body 3. One end of the screw 309 is rotatably connected to the vibratory hammer body 3, and the extrusion plate 310 is slidably connected to the vibratory hammer body 3.

[0034] The above technical solution uses the latch 311 to fix the ring 307, preventing the ring 307 from rotating after long-term use and causing the pressing plate 310 to loosen.

[0035] Please see Figure 3 The other end of the extrusion plate 310 is provided with an inclined angle, and the outer end of the swivel ring 305 is provided with a slot that is compatible with the extrusion plate 310.

[0036] Through the above technical solution, the extrusion plate 310 is set with an inclination angle to facilitate changing the direction of the force, pushing the tension seat 303 to hug the warning sleeve 302 tightly, and limiting the rotation ring 305 through the slot on the rotation ring 305.

[0037] Please see Figure 2-3 The linkage bevel gear 306 meshes with the synchronous bevel gear, and a cover plate is hinged to the outer end of the ring 307.

[0038] By using the above technical solution, a cover plate is set at the front end of the 307 ring, which reduces the impact of external factors.

[0039] Please see Figure 6 Both sides of the outer end of the base 102 are rotatably connected to knobs 103. One end of the knob 103 is fixedly connected to a gear 104. Both ends of the gear 104 are meshed with racks 105.

[0040] Through the above technical solution, by rotating the knob 103, the knob 103 drives the gear 104 to rotate, and the gear 104 drives the racks 105 on both sides to move in opposite directions, so that the racks 105 are inserted into the main beam 1, thereby limiting the base 102. Rotating the knob 103 in the opposite direction cancels the limitation on the base 102.

[0041] Please see Figure 4 The main beam 1 is snapped into the base 102, and a slot is provided at the connection between the main beam 1 and the base 102.

[0042] Please see Figure 7 The piston rod 502 and the bracket 503 are slidably connected to the fixture body 5, and the first toothed plate 504 and the second toothed plate 505 are arranged opposite to each other.

[0043] Through the above technical solution, the clamp body 5 plays a limiting role for both the piston rod 502 and the bracket 503. The jaw plate 1 504 and jaw plate 2 505 are set opposite to each other, which facilitates clamping the upper side wall of the pipe pile.

[0044] Please see Figure 7 A pad is provided between the fixture body 5 and the fastening bolt.

[0045] Working principle: A ring-shaped vibratory frame is formed by the main beam 1 and the secondary beam 2. Twelve vibratory hammer bodies 3 are installed on the main beam 1, facilitating the vibratory driving of large steel pipe piles. The twelve vibratory hammer bodies 3 are connected by a gearbox 4 to ensure consistent amplitude. A large clamping force is generated between the linkage shaft 301 and the diaphragm coupling 304 through the warning sleeve 302 and the tensioning seat 303, achieving a keyless connection. This protects the equipment from damage and solves the phase difference of the eccentric blocks between adjacent vibratory hammers. This is existing technology and will not be described in detail here. The expansion seat 303 is aligned with the warning sleeve 302 and inserted. It is limited by the insertion rod 313. The rotating ring 307 is rotated. The rotating ring 307 drives the screw 309 to rotate through the conical tooth group 308. The screw 309 pushes the extrusion plate 310, which extrudes the rotating ring 305, thereby making the expansion seat 303 and the warning sleeve 302 tightly connected, thus fixing the gearbox 4. This achieves the effect of facilitating quick disassembly and assembly of the gearbox 4 and making maintenance easier.
