[0021] Next, in conjunction with the accompanying drawings of the specification, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than 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 efforts shall fall within the protection scope of the present utility model.
[0022] Embodiment 1: In combination with Figure 1 - Figure 4 As shown, the present utility model provides a technical solution: a hydraulic pile hammer lifting mechanism, including a fixed seat 1, a sleeve 3 is arranged on one side of the fixed seat 1, and a pile hammer 4 is arranged in the sleeve 3;
[0023] A plurality of mounting seats 5 are fixedly installed around the top of the pile hammer 4, the plurality of mounting seats 5 are arranged in a circumferential array, and a guide wheel 51 is arranged on the mounting seat 5, and the guide wheel 51 is in sliding fit with the inner wall of the sleeve 3.
[0024] In the embodiment of the present invention, the pile hammer 4 is an indispensable important device in construction engineering. It drives the pile into the ground through a powerful impact force to provide a stable foundation for the building. During the operation of the pile driver, the lifting and lowering movement of the pile hammer 4 is one of the key links. To achieve this movement, the pile hammer 4 usually slides in the sleeve 3 through the guide wheel 51. This design not only enables the pile hammer 4 to be lifted and lowered smoothly, but also ensures the accuracy and stability of the movement of the pile hammer 4 through the guidance of the guide wheel 51;
[0025] Specifically, the guide wheel 51 plays a crucial role in the lifting and lowering movement of the pile hammer 4. It is located inside the sleeve 3 and is closely connected to the pile hammer 4. When the pile hammer 4 needs to rise or fall, it will move along the path set by the guide wheel 51. The guide wheel 51 is usually designed with excellent wear resistance and stability, and can withstand the huge force generated during the impact of the pile hammer 4. At the same time, the profile and material of the guide wheel 51 are also carefully designed and selected to ensure the smoothness and stability of the pile hammer 4 during the sliding process;
[0026] In actual operation, the pile hammer 4 can not only achieve precise lifting and lowering movement through the sliding of the guide wheel 51 in the sleeve 3, but also effectively reduce energy loss and mechanical wear. This design not only improves the working efficiency of the pile driver, but also extends the service life of the equipment. At the same time, the presence of the guide wheel 51 also makes the pile hammer 4 more stable during the movement, reducing potential safety hazards caused by shaking or deviation;
[0027] In summary, the guide wheel 51 plays a role in guiding the movement during the lifting and lowering of the pile hammer 4. Through precise design and high-quality materials, it ensures the accuracy, stability, and efficiency of the pile hammer 4 during the lifting and lowering process. This design not only improves the working performance of the pile driver but also provides a strong guarantee for the safety and quality of construction projects.
[0028] Embodiment 2: Combining Figure 1 As shown in the figure, on the basis of Embodiment 1, a support rod 2 is fixedly connected to the top of the fixed seat 1. The support rod 2 is fixedly connected to the outer wall of the upper end of the sleeve 3. A connecting seat 21 is fixedly connected to one side of the fixed seat 1 close to the support rod 2. The connecting seat 21 is fixedly connected to the outer wall of the bottom of the sleeve 3.
[0029] In the embodiment of the present invention, during the working process of the pile hammer, it is necessary to ensure the stability of the sleeve to ensure the accuracy and efficiency of pile driving. Therefore, the material selection of the support rod 2 is also very important. We have selected a high-strength and corrosion-resistant alloy material to ensure its stable performance in various harsh working environments. At the same time, we have also designed a connecting seat 21 for positioning the lower end of the sleeve 3. The connecting seat 21 adopts a special structural design and can be firmly fixed on the ground to prevent the sleeve 3 from moving during the working process. In addition, the connecting seat 21 also has a certain shock-absorbing function, which can effectively reduce the vibration generated during pile driving and protect the surrounding buildings and facilities;
[0030] Through this positioning method at both the upper and lower ends, we have successfully ensured the stability of the sleeve 3 when the pile hammer is working. This not only improves the accuracy and efficiency of pile driving but also greatly reduces the potential safety hazards during the working process. In practical applications, our this positioning method has been widely recognized and praised, providing a solid guarantee for the safety and quality of construction projects;
[0031] In short, by respectively positioning the upper and lower ends of the sleeve 3 through the provided support rod 2 and connecting seat 21, we have successfully ensured the stability of the sleeve 3 when the pile hammer is working. This positioning method not only improves the accuracy and efficiency of pile driving but also improves the safety and quality of construction projects.
[0032] Embodiment 3: Combining Figure 3 As shown in the figure, on the basis of Embodiment 2, a rope 41 is fixedly connected to the top of the pile hammer 4. On the other side of the rope 41, a winch 42 is provided. The winch 42 is installed on the fixed seat 1.
[0033] In the embodiment of the present invention, the winch 42 drives the rope 41 to be wound up, thereby driving the pile hammer 4 to move upward. When the pile hammer 4 moves upward to the required position and then is released, the pile hammer 4 freely falls, and the impact kinetic energy is used to squeeze the soil layer or break the rock layer to form a pile hole.
[0034] Embodiment 4: In combination with Figure 1 , Figure 3 As shown in Figure 1 and Figure 3 , on the basis of Embodiment 3, a rectangular box 31 is fixedly installed on the top of the fixed seat 1. A pulley 32 is rotatably connected inside the rectangular box 31, and the pile hammer 4 passes through the pulley 32.
[0035] A through groove is opened at the outer end of the sleeve 3, and a partition 33 is rotatably connected through a hinge at the through groove.
[0036] Guide grooves 34 are arranged in a circumferential array on the inner wall of the sleeve 3. The number of the guide grooves 34 corresponds to the number of the guide wheels 51, and the guide wheels 51 are located in the guide grooves 34 and are slidably connected with the sleeve 3.
[0037] In the embodiment of the present invention, the pulley 32 plays a crucial role on the rope 41, guiding the direction of the rope 41. When the pile hammer 4 moves inside the sleeve 3, the guide wheel 51 slides inside the guide groove 34. The guide groove 34 is like an accurate track, which ensures that the guide wheel 51 always maintains the correct direction during movement. This guiding effect enables the pile hammer 4 to move up and down accurately in the vertical direction, thus successfully completing the pile driving work.
[0038] In addition, this system also designs a unique maintenance mechanism. By opening the partition 33, people can conduct a comprehensive inspection and maintenance of the pile hammer 4, greatly improving the maintainability and service life of the equipment.
[0039] In practical applications, the guiding effects of the pulley 32 and the guide groove 34, as well as the vertical movement of the pile hammer 4, have been carefully designed and calculated. For example, the diameter, material, and installation position of the pulley 32 have all been strictly selected and tested to ensure that it can withstand huge tensile forces and accurately conduct guiding. Similarly, the shape, size, and surface treatment of the guide groove 34 have also been finely designed to ensure that the guide wheel 51 can slide smoothly therein.
[0040] In addition, the design of the pile hammer 4 also fully considers its working characteristics and usage environment. It is made of high-strength materials to withstand the huge impact force generated during pile driving. At the same time, its internal structure has also been optimized to improve the energy transfer efficiency and reduce energy loss. These elaborate designs and optimizations enable the entire pile driving system to complete the pile driving task efficiently and accurately.
[0041] Generally speaking, the guiding effect of the pulley 32 on the rope 41, the guiding effect of the guiding groove 34 on the guiding wheel 51, and the up-and-down movement of the pile hammer 4 in the vertical direction are all important components in this pile driving system. They work together to enable the entire pile driving process to proceed smoothly. At the same time, the mechanism of opening the partition plate 33 for maintenance also reflects the flexibility and maintainability of this system. These features make this pile driving system have wide applicability and high reliability in practical applications.
[0042] Working principle: The winch 42 drives the rope 41 to wind up, thereby driving the pile hammer 4 to move upward. The pulley 32 plays a guiding role in the rope 41. When the pile hammer 4 moves within the sleeve 3, the guiding wheel 51 slides within the guiding groove 34, and the guiding groove 34 plays a guiding role in the guiding wheel 51 to ensure that the pile hammer 4 moves up and down in the vertical direction. When the pile hammer 4 moves up to the required position and then is released to let the pile hammer 4 free fall, the impact kinetic energy is used to squeeze the soil layer or break the rock layer to form a pile hole.
[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
