Description

Technical Field

[0001] The utility model relates to the technical field of pile drivers, in particular to a pile driver with a lifting mechanism. Background Art

[0002] Pile drivers can be divided into hydraulic hammer pile drivers, spiral pile drivers, etc. Pile drivers drive precast concrete piles or steel pipe piles into the ground, making the constructed houses more solid and less likely to collapse. Spiral pile drivers are a type of piling equipment that uses a power head to drive the drill rod and drill bit to spirally drill holes underground.

[0003] According to a pile driver mentioned in China's utility model CN201910348050.1, when used, the pile driver can realize that the pile driver can not only drive piles on the shallow layer of the foundation soil, but also complete pile driving operations on the deep layer of the foundation, which expands the range of pile driving depth operations of the pile driver and improves the construction efficiency of the pile driver. However, the pile driver does not have a buffer mechanism in actual use, which leads to the inability to use the drill bit for buffering when encountering relatively hard objects, which can easily cause large drill bits or equipment damage. Therefore, it is necessary to propose a pile driver with a lifting mechanism to solve the above-mentioned related problems. Utility Model Content

[0008] Furthermore, the two second buffer springs are respectively arranged on the sides of the two sliding blocks facing away from each other.

[0009] Furthermore, a slide groove is provided on the inner wall of the buffer box, a slider is slidably installed inside the slide groove, and the slider is fixedly connected to the second buffer plate.

[0010] Furthermore, the lifting mechanism includes a driving motor, and the driving motor is fixedly installed on the rear side of the fixing plate. A gear is fixedly connected to the output shaft of the driving motor, and gear plates are mutually meshed on the outer surfaces of the gears.

When encountering a relatively hard object, the drill bit and the motor components can be buffered without causing damage to the drill bit. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 , a pile driver with a lifting mechanism in this embodiment includes a fixed plate 1, a buffer box 3 is movably mounted on the left side of the fixed plate 1, a motor 4 is fixedly connected to the bottom of the buffer box 3, a drill bit 5 is fixedly connected to the output shaft of the motor 4, a buffer mechanism 9 is fixedly mounted on the internal movable of the buffer box 3, a lift mechanism 12 is installed on the internal movable of the fixed plate 1, a fixed base base 2 is fixedly connected to the top of the fixed base base 2, and a hydraulic telescopic rod 7 is fixedly connected to the output shaft of the hydraulic telescopic rod 7 is fixedly connected to the stabilizing plate 8;

[0020] The buffer mechanism 9 includes a first buffer plate 901, and the internal movable of the buffer box 3 is equipped with a first buffer plate 901. The top of the first buffer plate 901 is fixedly connected with a hydraulic damper 902 and a first buffer spring 903. The top of the first buffer spring 903 and the hydraulic damper 902 is fixedly connected with a second buffer plate 904. The inner cushion box 3 is fixedly connected with a slide bar 905. The outer surface of the slide bar 905 is connected with a second buffer spring 907 of two, and the outer surface of the slide bar 905 is connected with a sliding block 906 of two.

[0021] In specific implementation, by setting up the buffer mechanism 9, when in use, when the drill bit 5 encounters resistance from bottom to top, the hydraulic damper 902 and the first buffer spring 903 will be compressed and blocked at the same time, and the first buffer plate 901 and the second buffer plate 904 will be driven to slide upward inside the buffer box 3 at the same time. The upward buffering resistance force will drive the sliding block 906 to slide and buffer on both sides of the outer surface of the sliding rod 905 through the first hinge rod 909 and the second hinge rod 910. Through the action of the hydraulic damper 902, the first buffer spring 903, the second buffer spring 907 and the second buffer plate 904, the buffering stroke of the drill bit 5 can be increased, and the buffering and shock-absorbing effect of the vibration generated by the drill bit 5 when the pile driver is working can be achieved. When encountering a relatively hard object, the drill bit 5 and the motor 4 can be buffered without causing damage to the drill bit 5.

[0022] By setting up a lifting mechanism 12, the output shaft of the driving motor 121 drives the gear 122 to rotate, and the gear 122 and the gear plate 123 are meshed with each other, so that the gear 122 drives the gear plate 123 to move up and down. The process of the gear plate 123 moving up and down will simultaneously drive the buffer box 3, the motor 4 and the drill bit 5 to move up and down, and the reciprocating motion realizes piling on the ground.

[0023] Through the action of the hydraulic telescopic rod 7 and the stabilizing plate 8, the fixed base 2 and the fixed plate 1 can be kept in a stable state during piling, thereby ensuring the stability of piling; through the action of the limiting through groove 124 and the moving block 125, the gear plate 123 can drive the buffer box 3, the agricultural machinery 4 and the drill bit 5 to rise and fall smoothly, and at the same time, through the joint action of the slide groove 10 and the slider 11, the second buffer plate 904 can maintain a stable movement process.

[0024] When implementing, follow these steps:

[0025] 1) First, the output shaft of the hydraulic telescopic rod 7 drives the stabilizing plate 8 to descend, so as to keep the fixed base 2 and the fixed plate 1 in a balanced state;

[0026] 2) Then start the drive motor 121;

[0027] 3) The buffer box 3, the motor 4 and the drill bit 5 are driven downward by the lifting mechanism 12;

[0028] 4) Finally, the buffer mechanism 9 can provide safety protection for the motor 4 and the drill bit 5 .

[0029] In summary, the pile driver with a lifting mechanism is provided with a buffer mechanism 9. When the drill bit 5 is in use and encounters resistance from bottom to top, the hydraulic damper 902 and the first buffer spring 903 will be compressed and blocked at the same time, and the first buffer plate 901 and the second buffer plate 904 will be driven to slide upward inside the buffer box 3 at the same time. The upward buffering resistance force will drive the sliding block 906 to slide and buffer on both sides of the outer surface of the sliding rod 905 at the same time through the first hinge rod 909 and the second hinge rod 910. Through the action of the hydraulic damper 902, the first buffer spring 903, the second buffer spring 907 and the second buffer plate 904, the buffering stroke of the drill bit 5 can be increased, and the buffering and shock-absorbing effect of the vibration generated by the drill bit 5 when the pile driver is working can be achieved. When encountering a relatively hard object, the drill bit 5 and the motor 4 can be buffered without causing damage to the drill bit 5.
