[0001] This utility model relates to the field of pile head protection technology, and in particular to a pile head protection and fixing device for pile driving machines. Background Technology

[0002] The pile head protection and fixing device for pile driving machines is an important auxiliary device used during pile driving machine operation. It is fitted onto the pile head of the pile driving machine, and its main function is to effectively protect and firmly fix the pile head during the pile driving process. Through this device, the pile head can be prevented from being damaged under strong pressure, ensuring that the pile head can be accurately and vertically pressed into the ground, thereby improving the accuracy and quality of pile driving and ensuring the smooth progress of the pile driving project.

[0003] In existing technologies, fixing devices can often only be adapted to piles of a specific diameter, which limits the flexibility and efficiency of construction. Frequent replacement of fixing devices of different specifications increases the complexity and difficulty of construction, resulting in a cumbersome construction process, affecting the construction progress, and increasing labor and time costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a pile head protection and fixing device for pile drivers, which aims to improve the problem of frequent replacement of different specifications of existing fixing devices affecting the construction progress.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the worm is driven to rotate by a motor. When the worm rotates, it drives the worm wheel to rotate. The worm wheel drives the helical teeth to rotate, thereby causing the three racks and sliding blocks at the top to slide in the groove. This enables the three clamping parts to clamp and fix piles of different diameters, so that it can adapt to the construction needs of piles of various specifications and reduce the time and cost of replacing or adjusting the equipment due to differences in pile diameter.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1-3 This utility model provides an embodiment of a pile head protection and fixing device for a pile driver, comprising a fixing component 1, a connecting plate 2 fixedly connected to the right side of the fixing component 1, a motor 3 fixedly connected to the bottom of the connecting plate 2, a worm gear 4 fixedly installed at the output end of the motor 3, a worm wheel 5 meshing with the left side of the worm gear 4, a helical tooth 11 fixedly connected to the top of the worm wheel 5, three sliding grooves 18 opened on the surface of the fixing component 1, sliding blocks 10 slidably connected in each of the three sliding grooves 18, racks 19 fixedly connected to the bottom of each of the three sliding blocks 10, clamping components 9 fixedly connected to adjacent sides of each of the three racks 19, a connecting component 7 provided at the top of the fixing component 1, and a disassembly assembly provided at the bottom of the connecting component 7 for quick disassembly.

[0025] Specifically, the motor 3 drives the worm gear 4 to rotate, which in turn drives the worm wheel 5 to rotate. The worm wheel 5 then drives the helical gear 11 to rotate, and the rotation of the helical gear 11 drives the rack 19 to move. This causes the three racks 19 and the sliding block 10 at the top to slide within the groove 18. When the three racks 19 and the sliding block 10 come together, the three clamping parts 9 clamp and fix the piles of different diameters, thus adapting to the construction needs of piles of various specifications and reducing the time and cost of replacing or adjusting the equipment due to differences in pile diameter.

[0026] Reference Figure 1 and Figure 5 The disassembly assembly includes four cylinders 8. The top of each of the four cylinders 8 is fixedly connected to the connector 7. A sliding ring 6 is fixedly connected between the output ends of the four cylinders 8. The sliding ring 6 is slidably connected to the connector 7. Four balls 15 are slidably connected inside the connector 7. The inner diameter of the sliding ring 6 has four holes 20.

[0027] Specifically, the cylinder 8 pushes the sliding ring 6 to move. When the sliding ring 6 moves upward, the groove 20 is at the same height as the ball 15. At this time, the ball 15 can roll into the groove 20. Then the connecting block 16 at the bottom can be pulled out. When installation is required, the sliding ring 6 is moved upward and the connecting block 16 is inserted into the connector 7. At this time, the sliding ring 6 moves downward and squeezes the ball 15, so that the ball 15 fits tightly with the groove 17 on the connecting block 16, thereby realizing the quick installation and disassembly of the bottom fixing device.

[0028] Reference Figure 5 The top of the fastener 1 is fixedly connected to a connecting block 16, and the connecting block 16 has circular grooves 17 on all four sides.

[0029] Specifically, the circular groove 17 is used to fix the connecting block 16 to prevent it from falling off when the ball 15 is inserted.

[0030] Reference Figure 4 A hydraulic buffer 13 is fixedly connected to the top of the inner wall of the fastener 1, and a protective pad 14 is fixedly connected to the output end of the hydraulic buffer 13.

[0031] Specifically, the hydraulic buffer 13 is used in the process of pile driving, when the pile head comes into contact with the ground, a huge impact force is generated. The hydraulic buffer 13 can convert this impact force into heat energy and hydraulic energy through the internal hydraulic oil flow and throttling effect, thereby effectively absorbing and mitigating the impact and protecting the pile head and the device itself.

[0032] Reference Figure 4 The top of the pad 14 is fixedly connected with evenly distributed springs 12, and the tops of the multiple springs 12 are fixedly connected to the fixing member 1.

[0033] Specifically, during the pile driving process, the spring 12 can store some energy and release it at the appropriate time, which helps to maintain the continuity and stability of the pile driving. When the pile driving action is completed, the elastic restoring force of the spring 12 can help the protective pad 14 return to the initial position, preparing for the next pile driving operation.

[0034] Reference Figures 1-3 The top of the worm gear 5 is rotatably connected to the fixed part 1, and the three racks 19 are all meshed with the helical teeth 11.

[0035] Specifically, the rotation of the worm gear 5 drives the rotation of the helical gear 11. Due to the self-locking characteristic between the worm gear 5 and the worm 4, the pile body is securely clamped and fixed.

[0036] Reference Figure 5 The four spheres 15 are all tightly fitted with their adjacent circular grooves 17.

[0037] Specifically, the connection between the sphere 15 and the groove 17 enables the quick installation and removal of the fixing device.

[0038] Reference Figure 2 and Figure 3 The three clamping parts 9 are all arc-shaped on one side of each other, and the surfaces of the three clamping parts 9 on one side of each other are all coated with rubber.

[0039] Specifically, the arc-shaped clamping component 9 can better conform to the shape of the pile head. The arc-shaped design can provide a more uniform clamping force, reduce local pressure concentration, and thus reduce the risk of damage to the pile head. The rubber has a large coefficient of friction, which can enhance the friction between the clamping component 9 and the pile head, making the pile head more stable and less prone to slippage during the clamping process.

[0040] Working principle: When using the pile head protection and fixing device of this pile driver, the user first connects the fixing device to the pile driver through the connector 7, starts the motor 3, the motor 3 drives the worm 4 to rotate, the worm 4 drives the worm wheel 5 to rotate, the spiral teeth 11 at the top of the worm wheel 5 rotate accordingly, driving the rack 19 to move, so that the three racks 19 at the top and the sliding block 10 slide and move closer in the groove 18, and the three clamping parts 9 clamp and fix the piles of different diameters. During the pile driving process, the hydraulic buffer 1 at the top of the inner wall of the fixing part 1... 3, together with its output end pad 14 and top spring 12, absorbs and reduces impact force. When it is necessary to disassemble the fixing device, the starting cylinder 8 pushes the sliding ring 6 to move upward, the hole groove 20 is at the same height as the ball 15, the ball 15 rolls into the hole groove 20, and the bottom connecting block 16 can be pulled out. During installation, the sliding ring 6 is moved upward, the connecting block 16 is inserted into the connector 7, the sliding ring 6 moves downward, and the ball 15 is squeezed to fit tightly with the circular groove 17 on the connecting block 16, so as to achieve quick installation and disassembly.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
