Description

Technical Field

[0001] The invention relates to the technical field of pile drivers, in particular to a pile driver with anti-dumping protection. Background Art

[0002] Large equipment such as pile drivers have many requirements when operating, not only to ensure the normal use of the equipment, but also to ensure the safety of the operators. In large-scale projects, pile drivers are used to drive piles into the ground as the foundation of the supporting structure. Pile drivers can provide strong support and stability by driving piles into the soil quickly and evenly.

[0003] Existing pile drivers include two types: vibrating chuck vibrating pile drivers and hydraulic hammer piling drivers. Both have disadvantages when used:

[0004] 1. Vibration piling will generate a lot of noise that affects the surrounding environment and makes people feel uncomfortable. The vibration will loosen the surrounding soil and cause the machine to fall over.

[0005] 2. Hammer-type piling has a relatively large mechanical structure and needs to be set on a corresponding guide bracket for use with a hydraulic hammer. This is not convenient for loading piles and requires other machinery to clamp and swing the piles vertically for use. This is inconvenient to operate and requires a larger construction site.

[0021] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0022] 1. The present invention can realize effective hammer-type piling operation by arranging a piling mechanism and a bracket mechanism, avoid the noise of vibration piling and the damage to soil quality, ensure the stability of the machine during piling, avoid the dumping of the machine, and simplify the structure of hammer-type piling, without the need for a large construction site, so that the piling loading is automated and the piling operation is stable and convenient.

[0023] 2. The present invention sets a bracket mechanism. When the first hydraulic rod and the second hydraulic rod perform push-pull movements synchronously, they can drive the installation cylinder to perform position adjustment operations. When the third electric push rod pushes the support plate to fit the ground, it can support and stabilize the installation cylinder and the transfer vehicle. In this way, the pile driving position can be adapted to constrain the pile column while ensuring the stable support of the machine, making the pile driving operation more convenient.

[0024] 3. The present invention sets a pile driving mechanism, and the second electric push rod pushes and pulls the mounting block to clamp the clamp block on the side of the pile column. The first motor drives the clamp block to rotate, so that the pile column rotates accordingly. The swing arm swings vertically, ensuring the automatic clamping and swinging pile column operation, which can effectively prevent the pile column from falling off.

[0025] Then the first electric push rod pushes the second constraint plate downward, so that the second constraint plate, the third constraint plate and the first constraint plate can slide out of the first slot one by one in sequence, constraining piles of different specifications and ensuring the stability of the hammer-driven pile constraint.

[0026] 4. The present invention sets a driving mechanism, and the fourth electric push rod drives the second gear to engage and rotate with the first gear ring plate. The first detection block detects the position distance of the connecting shaft to determine whether the second gear is engaged with the first gear or the first gear ring plate. When the first gear ring plate is driven, it can drive the adjustment plate to rotate. At this time, the first guide rod slides in the guide groove to constrain the guide block to slide in the second slot, so that all guide blocks can adjust their positions to guide the piles, thereby ensuring stable constraints on piles of different specifications.

[0027] 5. The present invention sets a driving mechanism and a guiding mechanism. The fourth electric push rod drives the second gear to rotate in mesh with the first gear. The first driving rod and the second driving rod rotate respectively to engage with the slider. At this time, the slider on the side of the first driving rod slides downward in the sliding groove, and the slider on the side of the second driving rod slides upward in the sliding groove. Similarly, changing the rotation direction of the first gear drive can change the sliding direction of the sliders on the sides of the first driving rod and the second driving rod, thereby realizing the opposite synchronous movement operation of the sliders at corresponding positions, so that the pile column can be assisted in the downward movement operation during piling, thereby improving the stability and efficiency of piling. In addition, only a single set of second motors is needed to drive other components, thereby reducing the energy consumption of equipment.

[0028] 6. The present invention sets a bracket mechanism and a guiding mechanism. When the slider moves downward, the second guiding rod is guided to make the movable rod push the fixed block to fit and squeeze the side of the pile column to complete the auxiliary downward movement operation. When the slider moves upward, the movable rod is reset under the elastic force of the second supporting tube, so that the fixed block is away from the side of the pile column to avoid interference in the alternate downward movement of the slider. The second detection block arranged inside can detect the distance between the second guiding rod and the movable rod in real time. When the distance changes asynchronously, it can be known that the pile column is not vertical. The two-way angle adjustment of the installation tube is completed by alternately pushing and pulling the second hydraulic rod and the third electric push rod, and the angle compensation of the pile column is performed to keep the vertical piling in real time. In this way, the real-time detection of the verticality of the pile column and the adjustment and correction can ensure the piling effect.

[0029] 7. The present invention sets a cleaning mechanism, and the pile driving mechanism and the second driving rod rotate synchronously to drive the third gear to mesh with the second gear ring plate. The fifth electric push rod pushes the grinding belt to make it fit on the side of the pile column. When the second gear ring plate drives the guide plate and the fixed plate to rotate, the grinding belt can grind and clean the pile column. Conversely, the cleaning operation can also be performed when the pile is pulled out, thereby reducing the resistance on the side of the pile column during piling and facilitating the direct storage operation of the pile column after the pile is pulled out.

[0047] The piling mechanism 3 can be used to self-clamp the pile and constrain the piling operation;

[0048] like Figure 1 and Figures 3 to 5 As shown, the pile driving mechanism 3 includes a pile driving hammer 31 rotatably mounted on the side of the swing arm 2. The pile driving hammer 31 can be driven by hydraulic pressure to rotate on the side of the swing arm 2. The pile driving hammer 31 is a hydraulic hammer driven by an internally connected hydraulic oil circuit. The hammer head is lifted and freely falls to hammer the pile column through hydraulic drive. A first slot 32 is provided on the lower side of the pile driving hammer 31. The first slot 32 is an annular slot. A first constraint plate 321 is movably mounted at an upper position inside the first slot 32. A second constraint plate 322 is movably mounted at a lower position inside the first slot 32. The first constraint plate 321 and the second constraint plate 322 are annular plates with an "L"-shaped cross section. A third constraint plate 323 is movably mounted inside the first slot 32. The third constraint plate 32 The third constraint plate 323 is arranged between the first constraint plate 321 and the second constraint plate 322. The third constraint plate 323 is a circular ring plate. Constraint blocks 324 are fixedly installed at equal distances on both sides of the third constraint plate 323, and the constraint blocks 324 respectively penetrate into the first constraint plate 321 and the second constraint plate 322. The constraint blocks 324 are cylindrical blocks. The first electric push rod 33 is fixedly installed at equal distances on the upper side of the second constraint plate 322, and the first electric push rod 33 is fixedly installed in the internal position of the pile hammer 31. Specifically, the second constraint plate 322 is pushed downward by the first electric push rod 33, so that the second constraint plate 322, the third constraint plate 323 and the first constraint plate 321 can be conveniently slid out of the first slot 32 one by one in sequence, so as to play a constraint operation on piles of different specifications.

[0049] The two sides of the pile hammer 31 are fixedly mounted with a fixing frame 34 in a mirror image and are reinforced by a connecting piece. A second electric push rod 35 is fixedly mounted inside the fixing frame 34. A mounting block 36 is fixedly mounted at the output end of the second electric push rod 35. The mounting block 36 is a rectangular block. A first motor 37 is fixedly arranged inside the mounting block 36. A clamping block 38 is fixedly mounted at the output end of the first motor 37 and the clamping block 38 is movably arranged at an internal position of the mounting block 36.

The support plate 45 is a rectangular block; specifically, when the first hydraulic rod 42 and the second hydraulic rod 43 perform push-pull movements synchronously, the installation cylinder 41 can be driven to perform position adjustment operations. When the two groups of second hydraulic rods 43 perform push-pull operations and the first hydraulic rod 42 does not perform push-pull operations, the installation cylinder 41 can be rotated with the first hydraulic rod 42 as the axis to adjust the angle. Similarly, when the third electric push rod 44 pushes the support plate 45 to fit the ground, it can support and stabilize the installation cylinder 41 and the transfer vehicle 1. One group of third electric push rods 44 pushes another group of third electric push rods 44 to pull the installation cylinder 41 to adjust the angle in another direction.

The sliders 65 on the sides of the first driving rod 63 and the second driving rod 64 are respectively arranged at the uppermost and lowermost positions in the slide groove 61; specifically, when the first gear 52 is driven to rotate synchronously, the first driving rod 63 and the second driving rod 64 are respectively rotated to engage with the slider 65, at which time the slider 65 on the side of the first driving rod 63 slides downward in the slide groove 61, and the slider 65 on the side of the second driving rod 64 slides upward in the slide groove 61. Similarly, changing the driving rotation direction of the first gear 52 can change the sliding direction of the sliders 65 on the sides of the first driving rod 63 and the second driving rod 64, thereby realizing the opposite synchronous movement operation of the sliders 65 at the corresponding positions;

The side is close to the clamping, and the fixed block 662 is elastically clamped on the side of the pile column to move it downward. Similarly, when the slider 65 slides upward, the fixed block 662 moves away from the side of the pile column under the elasticity of the second support tube 666, wherein the second detection block 665 is set to detect the distance between the movable rod 661 and the second guide rod 663 and feed it back to the external controller. The controller can obtain whether the pile column is vertical based on the data, and the controller can control the third electric push rod 44 and the second hydraulic rod 43 to push and pull to realize the two-way angle adjustment of the installation tube 41 to correct the deviation of the pile column;

[0058] The cleaning mechanism 7 can clean the side of the pile column during piling.

[0059] like Figure 8 , Fig.10 , Fig.12 and Fig.13As shown, the cleaning mechanism 7 includes a connecting groove 71 opened on the lower side of the mounting cylinder 41, the connecting groove 71 is a circular ring groove with an "L"-shaped cross-section, and third gears 72 are equidistantly arranged in an array in the inner circumference of the connecting groove 71, and the third gears 72 are fixedly mounted on the bottom sides of the first drive rod 63 and the second drive rod 64 respectively, and a second gear ring plate 73 is meshed and sleeved on the side of the third gear 72, and the second gear ring plate 73 is movably mounted inside the connecting groove 71, the second gear ring plate 73 is a circular ring plate with teeth on the inner side, and a grinding belt 74 is arranged on the lower side of the mounting cylinder 41, and the grinding belt 74 is a flexible grinding "O"-shaped belt, and a fixing plate 75 is symmetrically fixedly installed on the lower side of the second gear ring plate 73 and the fixing plate 75 extends out of the connecting groove 71, the fixing plate 75 is a rectangular block, and a second spring 76 is fixedly connected between the fixing plate 75 and the side of the grinding belt 74, and the fixing plate 75 is staggered at the lower side of the second gear ring plate 73 The guide plate 77 is fixedly installed in a mirror image and extends out of the connecting groove 71. The guide plate 77 is a rectangular block with rectangular grooves symmetrically opened on the side. The grinding belt 74 is movably installed in the rectangular groove on the side of the guide plate 77. A fifth electric push rod 78 is fixedly installed on the side of the guide plate 77 and the output end of the fifth electric push rod 78 is attached to the side of the grinding belt 74; specifically, when the first drive rod 63 and the second drive rod 64 are driven to rotate, the third gear 72 is synchronously engaged with the second gear ring plate 73, and the fifth electric push rod 78 pushes the grinding belt 74 to constrain it to slide inside the guide plate 77. At this time, the grinding belt 74 is attached to the side of the pile column. When the second gear ring plate 73 drives the guide plate 77 to rotate, it can drive the grinding belt 74 to perform a grinding operation on the pile column. On the contrary, the fifth electric push rod 78 is pulled to reset, and the grinding belt 74 is stretched by the elastic force of the second spring 76 so that the grinding belt 74 is separated from the side of the pile column.

[0060] Working principle:

[0061] Before piling: the swing arm 2 is swung to move the mounting block 36 to the side of the pile, and the second electric push rod 35 pushes the clamping block 38 to clamp one end of the side of the pile. The swing arm 2 drives the pile to be placed in a vertical state. At the same time, the mounting block 36 can drive the clamping block 38 to rotate to cooperate with the pile from horizontal to vertical, ensuring that the pile will not fall off when clamped;

[0062] After the pile is vertical, the first hydraulic rod 42 and the second hydraulic rod 43 push and pull synchronously to adjust the position of the installation tube 41 to match the pile driving position, and then the third electric push rod 44 pushes the support plate 45 to fit the support plate 45 on the ground to support and stabilize the installation tube 41 and the transfer vehicle 1, and the fourth electric push rod 58 pushes the second gear 582 to mesh with the first gear ring plate 552, and the second motor 57 drives the second gear 582 to mesh and rotate with the first gear ring plate 552, and adjusts the guide block 561 to slide inside the second slot 56 to adapt to the pile specifications, and inserts the pile downward into the installation tube 41 and is guided to the ground by the guide block 561;

[0063] During piling: the first electric push rod 33 pushes the second constraint plate 322 downward so that the second constraint plate 322, the third constraint plate 323 and the first constraint plate 321 slide out of the first slot 32 one by one to constrain one side of the pile column, and the pile hammer 31 works to perform the piling operation, and the synchronous fourth electric push rod 58 pushes the second gear 582 to engage with the first gear 52, and the second motor 57 drives the first gear 52 to rotate synchronously, and the first driving rod 63 and the second driving rod 64 rotate synchronously to drive the slider 65 on the side thereof to move up and down alternately, completing the auxiliary downward movement operation on one side of the pile column, and the second motor 57 changes the driving rotation direction to move up and down alternately for the second time, completing another auxiliary downward movement operation;

[0064] When the slider 65 moves downward, the second guide rod 663 is guided to make the movable rod 661 push the fixed block 662 to fit and squeeze the side of the pile column to complete the auxiliary downward movement operation. When the slider 65 moves upward, the movable rod 661 is reset under the elastic force of the second support tube 666, so that the fixed block 662 is away from the side of the pile column to avoid interference in the alternate downward movement of the slider 65. The second detection block 665 arranged inside can detect the distance between the second guide rod 663 and the movable rod 661 in real time. When the distance changes asynchronously, it can be known that the pile column is not vertical. The two-way angle adjustment of the installation tube 41 is completed by alternately pushing and pulling the second hydraulic rod 43 and the third electric push rod 44, and the angle compensation of the pile column is performed to keep it vertically piled in real time.

[0065] When piling is in progress, the first driving rod 63 and the second driving rod 64 rotate the synchronous belt 53 to drive the third gear 72 to mesh with the second gear ring plate 73, and the grinding belt 74 is pushed by the fifth electric push rod 78 to make it fit the side of the pile column. When the second gear ring plate 73 drives the guide plate 77 and the fixed plate 75 to rotate, the grinding belt 74 can grind and clean the pile column to ensure the piling effect;

[0066] When pulling out the pile after piling: the entire components of the piling mechanism 3 are replaced and hoisted for use, the installation tube 41 is aligned with the piling position, the pile column is lifted and pulled out by hoisting, and the cleaning mechanism 7 is used to clean the pile column first, and the synchronously arranged guiding mechanism 6 can realize the auxiliary upward movement operation of the pile column, and the arranged driving mechanism 5 can constrain and limit the pile column, so that the pile column can be stably pulled out and cleaned, which is convenient for collection for subsequent use.

[0067] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
