Description

Technical Field

[0001] This utility model belongs to the field of pile driving technology, and in particular relates to a heavy hammer type pile driving machine. Background Technology

[0002] In the prior art, a search revealed a Chinese patent entitled "A Heavy Hammer Type Ramming and Expanding Pile Machine" with application number "CN202023166696.5". This patent mainly includes a chassis, a lifting frame mounted on the chassis, a heavy hammer mounted on the lifting frame, a pile cylinder mounted on the lifting frame and located outside the heavy hammer, a first winch mounted on the chassis, and a second winch mounted on the chassis. The first winch is used to connect with the heavy hammer, and the second winch is used to connect with the pile cylinder. It also includes a mounting shell for connecting with the first winch, a hook fixed on the outer wall of the mounting shell, and a movable rod movably mounted inside the mounting shell. The movable rod and the hook abut against each other to form a closed loop.

[0003] However, the design of the aforementioned ramming and expanding pile driver has a problem that cannot be ignored: the hammer and the wire rope are connected in a fixed manner. When the hammer is pulled up after completing the compaction operation and is ready for the next operation, the hammer will inevitably rotate. This rotation and torsion will accelerate the wear of the wire rope, greatly reduce its service life, and increase maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to provide a heavy-duty pile driver that improves the accuracy and efficiency of the pile driver during the compaction process by incorporating a rotating mechanism. This also reduces the wear of the wire rope, increases its service life, and lowers maintenance costs. Furthermore, it solves the problem that when the hammer and wire rope are fixedly connected, the hammer inevitably rotates when pulled up after compaction to prepare for the next operation. This rotation and torsion accelerates the wear of the wire rope, significantly reducing its service life and increasing maintenance costs.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a heavy hammer type ramming and expanding pile machine, including a base plate and a heavy hammer. The base plate is provided with a rotating mechanism, which includes a rotating component and a locking component. The rotating assembly includes a connecting lug plate fixedly connected to the top surface of the counterweight. A hook is provided on the inner wall of the connecting lug plate. A hook connecting shaft is fixedly connected to the outer wall of the hook. A connecting column is rotatably connected to the outer wall of the hook connecting shaft.

[0006] Furthermore, the locking assembly includes a pressing post slidably connected to the inner wall of the hook, a retaining ring fixedly connected to the outer wall of the pressing post, and a spring fixedly connected to the inner top wall of the hook, with the bottom end of the spring contacting the top end of the retaining ring.

[0007] Furthermore, a base is fixedly connected to the bottom surface of the base plate, a support plate is fixedly connected to the top surface of the base plate, a connecting shaft is fixedly connected to the inner wall of the support plate, and a lifting frame is rotatably connected to the outer wall of the connecting shaft.

[0008] Furthermore, a support mechanism is provided on the base plate; The support mechanism includes four first support rods hinged to the bottom surface of the hoisting frame. Each of the four first support rods has a pad hinged to its bottom end. A support column is fixedly connected to the bottom surface of the hoisting frame. A connecting block is slidably connected to the outer wall of the support column. Four second support rods are hinged to the outer wall of the connecting block. The ends of the four second support rods that are far apart from each other are hinged to the sides of the four first support rods that are close to each other.

[0009] Furthermore, a drive mechanism is provided on the base plate; The driving mechanism includes a first winch fixedly connected to the top surface of the base plate. The outer wall of the first winch is provided with two first wire ropes and a second wire rope. The inner wall of the hoisting frame is fixedly connected with two first connecting shafts. The outer walls of the two first connecting shafts are rotatably connected with two first pulleys. The outer walls of the two first connecting shafts are rotatably connected with second pulleys. The outer walls of the four first pulleys are in contact with the outer walls of the two first wire ropes respectively. The outer walls of the two second pulleys are in contact with the outer walls of the second wire ropes respectively. The end of the second wire rope away from the first winch is fixedly connected to the top surface of the connecting column.

[0010] Furthermore, four fixed lugs are fixedly connected to the ends of the two first wire ropes away from the first winch, and pile cylinders are fixedly connected to the bottom surfaces of the four fixed lugs.

[0011] Furthermore, a first connecting lug is fixedly connected to the top surface of the base plate, a support rod is hinged to the inner wall of the first connecting lug, and a connecting rod is hinged to the outer wall of the support rod.

[0012] Furthermore, two second connecting lugs are fixedly connected to the top surface of the base plate, and hydraulic telescopic rods are hinged to the inner walls of the two second connecting lugs. The ends of the two hydraulic telescopic rods away from the second connecting lugs are respectively hinged to the inner walls of the hoisting frame.

[0013] This utility model has the following beneficial effects: 1. By setting up a rotating mechanism, the hook connecting shaft on the hook will rotate inside the connecting column, thereby avoiding the twisting of the wire rope. The rotating mechanism compensates for the twisting of the wire rope when the hammer rises, improving the accuracy and efficiency of the ramming pile machine during the ramming process, while also reducing the wear of the wire rope, increasing its service life, and reducing maintenance costs.

[0014] 2. By setting up a support mechanism, when the hoisting frame is placed, the first support rod will spread out, and the pad at its bottom will play a role in stabilizing support. The support mechanism can effectively provide the extra stability required by the equipment during operation. During the compaction work, it ensures that the equipment can remain stable under various ground conditions, prevents accidental tilting or displacement, and thus ensures the accuracy and effectiveness of the operation.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 As shown, this utility model is a heavy hammer type ramming and expanding pile machine, including a base plate 1 and a heavy hammer 21. A rotating mechanism 2 is provided on the base plate 1, and the rotating mechanism 2 includes a rotating component and a locking component. The rotating assembly includes a connecting lug plate 22 fixedly connected to the top surface of the counterweight 21. A hook 23 is provided on the inner wall of the connecting lug plate 22. A hook connecting shaft 24 is fixedly connected to the outer wall of the hook 23. A connecting column 25 is rotatably connected to the outer wall of the hook connecting shaft 24.

[0021] Among them, such as Figure 5 As shown, the locking assembly includes a pressing post 31 slidably connected to the inner wall of the hook 23, a retaining ring 32 fixedly connected to the outer wall of the pressing post 31, and a spring 33 fixedly connected to the inner wall of the hook 23, with the bottom end of the spring 33 contacting the top end of the retaining ring 32.

[0022] With the rotating mechanism 2 in place, when the pressing column 31 is pulled up, the retaining ring 32 will compress the spring 33, allowing the counterweight 21 to be hung. Releasing the pressing column 31 will automatically reset it, preventing the counterweight 21 from falling off. When the counterweight 21 is lifted, it will rotate, causing the hook connecting shaft 24 on the hook 23 to rotate within the connecting column 25, thus preventing the wire rope from twisting. The rotating mechanism 2 compensates for the twisting of the wire rope when the counterweight 21 rises, improving the accuracy and efficiency of the ramming pile driver during the ramming process, while also reducing the wear of the wire rope, increasing its service life, and reducing maintenance costs.

[0023] Among them, such as Figure 1 As shown, a base 12 is fixedly connected to the bottom surface of the base plate 1, a support plate 13 is fixedly connected to the top surface of the base plate 1, a connecting shaft 14 is fixedly connected to the inner wall of the support plate 13, and a hoisting frame 15 is rotatably connected to the outer wall of the connecting shaft 14.

[0024] The stability of the rammed pile driver can be increased by setting the base 12. At the same time, a hydraulic lifting column 11 is set up so that when the rammed pile driver needs to be transported, the hydraulic lifting column 11 can be raised to lift the rammed pile driver, so that it can be placed on the transport machine. There is a connecting shaft 14 on the support plate 13 on the base plate 1. A hoisting frame 15 is rotatably connected to the connecting shaft 14. The hoisting frame 15 provides support for the mechanism set on it.

[0025] Among them, such as Figure 3 As shown, a support mechanism 3 is provided on the base plate 1; The support mechanism 3 includes four first support rods 41 hinged to the bottom surface of the hoisting frame 15. Each of the four first support rods 41 has a pad 42 hinged to its bottom end. A support column 43 is fixedly connected to the bottom surface of the hoisting frame 15. A connecting block 44 is slidably connected to the outer wall of the support column 43. Four second support rods 45 are hinged to the outer wall of the connecting block 44. The ends of the four second support rods 45 that are far apart from each other are hinged to the sides of the four first support rods 41 that are close to each other.

[0026] With the support mechanism 3 in place, when the hoisting frame 15 is positioned, the first support rod 41 will spread out, and the pad 42 at its bottom will provide stable support. At the same time, the connecting block 44 slides on the support column 43, and the second support rod 45 on the connecting block 44 will pull the first support rod 41 to provide more stable support. The support mechanism 3 can effectively provide the extra stability required by the equipment during operation. During the compaction work, the support mechanism ensures that the equipment remains stable under various ground conditions, preventing accidental tilting or displacement, thereby ensuring the accuracy and effectiveness of the operation.

[0027] Among them, such as Figure 2 As shown, a drive mechanism 4 is provided on the base plate 1; The drive mechanism 4 includes a first winch 51 fixedly connected to the top surface of the base plate 1. The outer wall of the first winch 51 is provided with two first wire ropes 52 and a second wire rope 54. The inner wall of the hoisting frame 15 is fixedly connected with two first connecting shafts 55. The outer walls of the two first connecting shafts 55 are rotatably connected with two first pulleys 56. The outer walls of the two first connecting shafts 55 are rotatably connected with second pulleys 57. The outer walls of the four first pulleys 56 are in contact with the outer walls of the two first wire ropes 52 respectively. The outer walls of the two second pulleys 57 are in contact with the outer walls of the second wire ropes 54 respectively. The end of the second wire rope 54 away from the first winch 51 is fixedly connected to the top surface of the connecting column 25.

[0028] By setting up a drive mechanism 4, the first winch 51 is started, and the first wire rope 52 slides on the first pulley 56. At the same time, the fixed ear plate 62 pulls the pile cylinder 61 to move, and then the pile cylinder 61 is released to bury it into the ground to a certain depth.

[0029] Among them, such as Figure 1 As shown, four fixed lugs 62 are fixedly connected to the ends of the two first wire ropes 52 away from the first winch 51, and pile cylinders 61 are fixedly connected to the bottom surfaces of the four fixed lugs 62.

[0030] By setting up a pile cylinder 61, the pile cylinder 61 can be buried to a certain depth in the ground. Then, the heavy hammer 21 is released to compact the material inside the pile cylinder 61. After that, the material is filled in again and compaction continues until the task is completed. The pile cylinder 61 can protect the pile body from lateral impact and soil erosion that may occur during the compaction process, and also ensure the integrity of the pile body.

[0031] Among them, such as Figure 1 As shown, a first connecting lug 71 is fixedly connected to the top surface of the base plate 1, a support rod 72 is hinged to the inner wall of the first connecting lug 71, and a connecting rod 73 is hinged to the outer wall of the support rod 72.

[0032] By providing a first connecting lug 71, a support rod 72 on the first connecting lug 71 can be connected to a connecting rod 73. At the same time, the support rod 72 provides support for the hydraulic telescopic rod 82, enhancing the stability of the hydraulic telescopic rod 82.

[0033] Among them, such as Figure 2 As shown, two second connecting lugs 81 are fixedly connected to the top surface of the base plate 1. The inner walls of the two second connecting lugs 81 are hinged with hydraulic telescopic rods 82. The ends of the two hydraulic telescopic rods 82 away from the second connecting lugs 81 are respectively hinged to the inner wall of the hoisting frame 15.

[0034] By providing a second connecting lug 81, the hydraulic telescopic rod 82 on the second connecting lug 81 can extend and retract, thereby controlling the lifting and lowering of the hoisting frame 15 and improving the working efficiency of the pile driver.

[0035] One specific application of this embodiment is as follows: by setting up a rotating mechanism 2, when the pressing column 31 is pulled up, the retaining ring 32 will squeeze the spring 33, at which time the hammer 21 can be hung. When the pressing column 31 is released, it will automatically reset and block the hammer 21 to prevent it from falling off. When the hammer 21 is lifted, it will rotate. At this time, the hook connecting shaft 24 on the hook 23 will rotate inside the connecting column 25, thereby avoiding the twisting of the wire rope. The setting of the rotating mechanism 2 compensates for the twisting of the wire rope when the hammer 21 rises, improves the accuracy and efficiency of the ramming pile machine in the ramming process, and at the same time reduces the wear of the wire rope, increases its service life, and reduces maintenance costs. The stability of the rammed pile driver can be increased by setting the base 12. At the same time, a hydraulic lifting column 11 is set up. When the rammed pile driver needs to be transported, the hydraulic lifting column 11 is raised so that the rammed pile driver can be lifted and placed on the transport machine. There is a connecting shaft 14 on the support plate 13 on the base plate 1. A hoisting frame 15 is rotatably connected to the connecting shaft 14. The hoisting frame 15 provides support for the mechanism set on it. With the support mechanism in place, when the hoisting frame 15 is in place, the first support rod 41 will spread out, and the pad 42 at its bottom will provide stable support. At the same time, the connecting block 44 slides on the support column 43, and the second support rod 45 on the connecting block 44 will pull the first support rod 41 to provide more stable support. The support mechanism 3 can effectively provide the extra stability required by the equipment during operation. During the compaction work, the support mechanism ensures that the equipment can remain stable under various ground conditions, prevents accidental tilting or displacement, and thus ensures the accuracy and effectiveness of the operation. With the drive mechanism 4 in place, the first winch 51 is started, and the first wire rope 52 slides on the first pulley 56. At the same time, the fixed ear plate 62 pulls the pile cylinder 61 to move. Then the pile cylinder 61 is released to bury it into the ground to a certain depth. The drive mechanism 4 improves the working efficiency of the rammed pile driver. By setting up a pile cylinder 61, the pile cylinder 61 can be buried into the ground to a certain depth. Then, the heavy hammer 21 is released to compact the material inside the pile cylinder 61. After that, the material is filled in again and compaction continues until the task is completed. The pile cylinder 61 can protect the pile body from lateral impact and soil erosion that may occur during the compaction process, and also ensure the integrity of the pile body. By providing a first connecting lug 71, a support rod 72 on the first connecting lug 71 can be connected to a connecting rod 73. At the same time, the support rod 72 provides support for the hydraulic telescopic rod 82, thereby enhancing the stability of the hydraulic telescopic rod 82. By providing a second connecting lug 81, the hydraulic telescopic rod 82 on the second connecting lug 81 can extend and retract, thereby controlling the lifting and lowering of the hoisting frame 15 and improving the working efficiency of the pile driver.
