Description

Technical Field

[0001] This utility model relates to the field of vibratory hammer technology, specifically to a hydraulic vibratory hammer hammering construction tool. Background Technology

[0002] A vibratory hammer is a device that generates a powerful vibration force when energized to drive objects into the ground. It belongs to the pile foundation construction machinery used in building engineering and is used for the construction of cast-in-place concrete piles. When matched with a pile frame, it can drive cast-in-place concrete piles, concrete expanded-base piles, lime piles, sand piles, and gravel piles. When equipped with a pile clamp, it can drive and extract precast concrete piles and various types of steel piles. It is an ideal piece of equipment for foundation construction of highways, bridges, airports, buildings, etc. In addition, the vibratory pile hammer can also be used as a pile driving hammer for vibratory pipe driving machines, plate inserting machines, and other machinery.

[0003] Hydraulic vibratory hammers are used in the construction of steel pipe piles. They are commonly used for driving sheet piles, steel pipe piles, and other pile foundations. However, existing hydraulic vibratory hammers generate significant vibration and noise during the hammering process because they act directly on the soil. Furthermore, their hammering efficiency is greatly affected by soil conditions and may impact the surrounding environment, increasing construction risks and failing to meet production needs. Therefore, a hydraulic vibratory hammer is proposed to address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hydraulic vibratory hammer for construction, which has the advantages of high construction efficiency and strong practicality. It solves the problems of existing hydraulic vibratory hammers, which are prone to generating large vibrations and noises during the hammering process because they act directly on the soil, and whose hammering efficiency is greatly affected by soil conditions, which may have an impact on the surrounding environment, increase construction risks, and fail to meet production needs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic vibratory hammer hammering construction fixture, including a fixture body, a connector fixedly installed on the lower surface of the fixture body, and a vibratory hammer fixedly installed at the bottom of the connector. The fixture body is provided with a shock-absorbing structure inside, and a drive mechanism is provided inside the fixture body.

[0006] The shock absorption structure includes a connecting rod that is oscillatingly connected inside the tooling body, a swing frame hinged to both ends of the connecting rod, a fixed block disposed at the bottom of the connecting rod, a limiting seat fixedly connected to the top of the fixed block, a moving rod rotatably installed between the swing frame and the limiting seat, and an adjustment assembly disposed between the two swing frames.

[0007] The drive mechanism includes a drive motor fixedly installed inside the tooling body, a transmission gear fixedly installed on the output shaft of the drive motor, a rotating shaft rotatably connected inside the tooling body, a driven gear fixedly connected to the outside of the rotating shaft, and rotating disks fixedly installed at both ends of the rotating shaft.

[0008] Furthermore, the connecting rod is hinged to the outside of the rotating disk, and there are two moving rods, which are distributed in an inclined manner between the swing frame and the fixed block.

[0009] Furthermore, the adjustment assembly includes threaded blocks rotatably installed inside the two swing frames, threaded rods threadedly connected inside the two threaded blocks, two movable plates threadedly connected to the outside of the threaded rods, and a spring fixedly connected between the two movable plates.

[0010] Furthermore, the number of the shock-absorbing structures is two sets, and the two sets of shock-absorbing structures are symmetrically distributed inside the tooling body.

[0011] Furthermore, a connecting plate is fixedly connected to the bottom of the fixing block, and the connecting plate is fixedly connected to the connector.

[0012] Furthermore, the drive motor is fixedly installed inside the tooling body via a mounting bracket, and the transmission gear and the driven gear are meshed with each other.

[0013] Furthermore, a limiting frame adapted to the rotating shaft is fixedly installed inside the tooling body, and both rotating disks are rotatably connected inside the tooling body.

[0014] Compared with the prior art, this utility model provides a hydraulic vibratory hammer hammering construction tool, which has the following beneficial effects:

[0015] 1. This hydraulic vibratory hammer hammering construction fixture, driven by a controller, starts the drive motor to rotate the transmission gear. The transmission gear meshes with the driven gear, thereby driving the rotating shaft and rotating disk to rotate. The connecting rod, along with the rotation of the rotating disk, causes the swing frame to swing around the hinge point, which in turn causes the moving rod to move between the swing frame and the limit seat. This allows the swing frame to absorb and disperse vibration energy during the swinging process, and the elastic deformation of the spring further absorbs and buffers the vibration energy, effectively enhancing the hammering ability of the vibratory hammer, achieving auxiliary excitation, improving construction efficiency, and achieving the advantage of high construction efficiency.

[0016] 2. This hydraulic vibratory hammer impact construction fixture changes the position of the threaded block within the swing frame by rotating the threaded rod, thereby adjusting the distance between the two moving plates and the preload of the spring. This allows the damping structure to adapt to different vibration environments and damping requirements, reducing the swaying and deformation of the fixture body under vibration, improving the stability and service life of the fixture, and achieving the advantage of strong practicality.

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 3 The hydraulic vibratory hammer impact construction fixture in this embodiment includes a fixture body 1, a connector 2 fixedly installed on the lower surface of the fixture body 1, and a vibratory hammer 3 fixedly installed at the bottom of the connector 2. The fixture body 1 is provided with a shock-absorbing structure and a drive mechanism. The shock-absorbing structure includes a connecting rod 4 swinging inside the fixture body 1, a swing frame 5 hinged to both ends of the connecting rod 4, a fixed block 8 set at the bottom of the connecting rod 4, a limiting seat 7 fixedly connected to the top of the fixed block 8, a moving rod 6 rotatably installed between the swing frame 5 and the limiting seat 7, and an adjustment component set between the two swing frames 5.

[0023] The connecting rod 4 is hinged to the outside of the rotating disk 18. There are two moving rods 6, which are inclinedly distributed between the swing frame 5 and the fixed block 8. The bottom of the fixed block 8 is fixedly connected to the connecting plate 9, which is fixedly connected to the connector 2. The connecting rod 4 drives the swing frame 5 to swing around the hinge point as the rotating disk 18 rotates, which in turn drives the moving rods 6 to move between the swing frame 5 and the limiting seat 7. This allows the swing frame 5 to absorb and disperse vibration energy during the swing process. The elastic deformation of the spring 13 further absorbs and buffers the vibration energy, effectively enhancing the hammering ability of the vibratory hammer 3, realizing auxiliary excitation, improving construction efficiency, and achieving the advantage of high construction efficiency.

[0024] Specifically, the adjustment assembly includes threaded blocks 10 rotatably mounted inside the two swing frames 5, threaded rods 11 threadedly connected inside the two threaded blocks 10, two movable plates 12 threadedly connected to the outside of the threaded rods 11, and a spring 13 fixedly connected between the two movable plates 12. By rotating the threaded rods 11, the position of the threaded blocks 10 within the swing frames 5 is changed, thereby adjusting the distance between the two movable plates 12 and the preload of the springs 13. This allows the damping structure to adapt to different vibration environments and damping requirements, reducing the swaying and deformation of the fixture body 1 under vibration.

[0025] It should be noted that there are two sets of damping structures, which are symmetrically distributed inside the main body 1 of the tooling.

[0026] In this embodiment, the drive mechanism includes a drive motor 14 fixedly installed inside the tooling body 1, a transmission gear 15 fixedly installed on the output shaft of the drive motor 14, a rotating shaft 16 rotatably connected inside the tooling body 1, a driven gear 17 fixedly connected to the outside of the rotating shaft 16, and rotating disks 18 respectively fixedly installed at both ends of the rotating shaft 16. The controller starts the drive motor 14 to drive the transmission gear 15 to rotate. The transmission gear 15 meshes with the driven gear 17, thereby driving the rotating shaft 16 and the rotating disk 18 to rotate. The connecting rod 4 will drive the swing frame 5 to swing around the hinge point as the rotating disk 18 rotates.

[0027] The drive motor 14 is fixedly installed inside the tooling body 1 via a mounting base, and the transmission gear 15 and the driven gear 17 are meshed with each other.

[0028] Specifically, a limiting frame adapted to the rotating shaft 16 is fixedly installed inside the tooling body 1, and both rotating disks 18 are rotatably connected inside the tooling body 1.

[0029] The working principle of the above embodiments is as follows:

[0030] In practical applications, the vibratory hammer 3 is mounted on the tooling body 1, the hydraulic pump is started, and the hydraulic system provides power to drive the vibratory hammer 3. The controller starts the drive motor 14, which drives the transmission gear 15 to rotate. The transmission gear 15 meshes with the driven gear 17, thereby driving the rotating shaft 16 and the rotating disk 18 to rotate. The connecting rod 4 will drive the swing frame 5 to swing around the hinge point as the rotating disk 18 rotates, which in turn drives the moving rod 6 to move between the swing frame 5 and the limit seat 7. This allows the swing frame 5 to absorb and disperse vibration energy during the swinging process, and the elastic deformation of the spring 13 further absorbs and buffers the vibration energy, effectively enhancing the hammering ability of the vibratory hammer 3 and achieving auxiliary excitation.

[0031] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections.

[0032] Any connection method that can achieve its beneficial effect can be implemented. In addition, all electrical components in this embodiment are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing public power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
