A pile driver with a shock absorption mechanism

Abstract

This utility model discloses a pile driver with a shock-absorbing mechanism, including a frame. A fixed plate is slidably connected to the top inner wall of the frame. A hammer head is fixedly installed on one side of the fixed plate. The frame is equipped with a shock-absorbing mechanism, which includes a slider, an electric cylinder, a mounting plate, spring dampers, and a groove. The electric cylinder is fixedly installed on the top of the inner wall of the frame. The output shaft of the electric cylinder is fixedly installed on the mounting plate. Two spring dampers are fixedly installed on the bottom of the mounting plate, and the bottom ends of the two spring dampers are close to and in contact with the fixed plate. After the hammer head rebounds after pile driving, it will drive the fixed plate to move upward. At this time, the electric cylinder will start and drive the mounting plate and spring dampers to move downward. When the spring dampers are moved to contact the surface of the fixed plate, they can limit and buffer the fixed plate, thereby buffering and reducing the shock when the hammer head rebounds, which facilitates subsequent continuous work.

Description

Technical Field

[0001] This utility model relates to the field of pile driver technology, specifically a pile driver with a shock absorption mechanism. Background Technology

[0002] Piling machines drive reinforced concrete piles, wooden piles, or steel piles vertically into the ground by applying impact or vibration, forming a stable foundation support.

[0003] Currently, when pile drivers drive piles onto pile plates, they typically use hammers to press the pile plate down. After pile driving, the hammers generate an upward elastic force, which reduces the continuous working efficiency of subsequent hammers. Therefore, a pile driver with a shock-absorbing mechanism needs to be designed. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide a pile driver with a shock-absorbing mechanism, thereby resolving the issues raised in the background section.

[0005] To achieve the above objectives, this utility model proposes a pile driver with a shock absorption mechanism, including a frame, a fixed plate slidably connected to the top inner wall of the frame, and a hammer head fixedly installed on one side of the fixed plate;

[0006] The frame is equipped with a shock absorption mechanism, which includes a slider, an electric cylinder, a mounting plate, spring dampers, and slide grooves. An electric cylinder is fixedly installed on the top of the inner wall of the frame, and the output shaft of the electric cylinder is fixedly installed on the mounting plate. Two spring dampers are fixedly installed on the bottom of the mounting plate, and the bottom ends of the two spring dampers are close to and in contact with the fixed plate. Slide grooves are opened on both sides of the inner wall of the frame, and sliders fixed to the fixed plate are slidably connected to the inner walls of the two slide grooves.

[0007] In one example, two support plates are fixedly installed on the top of the frame, and a horizontal plate is fixedly installed on the side of the two support plates that are close to each other.

[0008] In one example, two fixed shafts are fixedly installed on the side of the two cross plates that are close to each other, and rollers are rotatably connected to the outer ring of each of the two fixed shafts.

[0009] In one example, a base plate is fixedly mounted on one side of the frame, and a winch is fixedly mounted on the top of the base plate.

[0010] In one example, a steel cable is wound around the drum of the winch, the steel cable is wound around two rollers, and the other end of the steel cable is fixedly connected to a hammer.

[0011] In one example, connecting plates are fixedly installed on both sides of the frame, and square limiting rings are fixedly installed on one side of each of the two connecting plates.

[0012] The pile driver with a shock absorption mechanism proposed in this utility model can bring the following beneficial effects:

[0013] 1. This pile driver with a shock absorption mechanism, after the hammer head rebounds upwards after pile driving, it will drive the fixed plate to move upwards. At this time, the electric cylinder starts and drives the mounting plate and spring damper to move downwards. When the spring damper is moved to fit against the surface of the fixed plate, it can limit and buffer the fixed plate, thereby buffering and reducing the shock when the hammer head rebounds, which facilitates subsequent continuous work.

[0014] 2. This type of pile driver with a shock absorption mechanism uses a winch to wind up a steel cable, which is then pulled around a roller to lift the hammer. When the cable reaches its highest point, the winch's characteristics cause the hammer to descend, allowing it to press down on the pile plate within the square limiting ring for pile driving.

[0022] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0023] like Figures 1-5 As shown, an embodiment of this utility model proposes a pile driver with a shock absorption mechanism, including a frame 1, a fixing plate 3 slidably connected to the top inner wall of the frame 1, and a hammer head 4 fixedly installed on one side of the fixing plate 3.

[0024] The frame 1 is equipped with a shock absorption mechanism, which includes a slider 17, an electric cylinder 7, a mounting plate 6, a spring damper 5, and a slide groove 2. The electric cylinder 7 is fixedly installed on the top of the inner wall of the frame 1. The output shaft of the electric cylinder 7 is fixedly installed on the mounting plate 6. Two spring dampers 5 are fixedly installed on the bottom of the mounting plate 6. The bottom ends of the two spring dampers 5 are close to and in contact with the fixed plate 3. Slide grooves 2 are opened on both sides of the inner wall of the frame 1. The inner walls of the two slide grooves 2 are slidably connected to the slider 17 fixed to the fixed plate 3.

[0025] Specifically, two support plates 14 are fixedly installed on the top of the frame 1. A horizontal plate 13 is fixedly installed on the side of the two support plates 14 that are close to each other. The horizontal plate 13 is fixed by the support plates 14 and the fixed shaft 12 is fixed by the support plates 14.

[0026] Specifically, two fixed shafts 12 are fixedly installed on the side of the two horizontal plates 13 that are close to each other. Rollers 11 are rotatably connected to the outer ring of the two fixed shafts 12. The fixed shafts 12 fix the rollers 11, and the rollers 11 wind the steel cable 8.

[0027] Specifically, a base plate 10 is fixedly installed on one side of the frame 1, and a winch 9 is fixedly installed on the top of the base plate 10. The winch 9 is fixed by the base plate 10, and the winch 9 winds and winds up the steel cable 8.

[0028] Specifically, a steel cable 8 is wound around the drum of the winch 9. The steel cable 8 is wound around two rollers 11, and the other end of the steel cable 8 is fixedly connected to the hammer head 4. The hammer head 4 is fixed by the steel cable 8 and the hammer head 4 is driven to rise and fall.

[0029] Specifically, connecting plates 16 are fixedly installed on both sides of the frame 1, and square limiting rings 15 are fixedly installed on one side of each of the two connecting plates 16, and the square limiting rings 15 are fixed by the connecting plates 16.

[0030] Working principle: The piling plate is placed inside the square limiting ring 15. At this time, the winch 9 is started to wind up the steel cable 8 and pull it around the roller 11, which will drive the hammer head 4 to move upward and the fixed plate 3 to move upward. At this time, the electric cylinder 7 moves synchronously and drives the mounting plate 6 and the spring damper 5 to move upward synchronously. Then the winch 9 is turned off. At this time, the hammer head 4 moves downward under the action of gravity and presses down on the piling plate inside the square limiting ring 15 to drive the pile. At the same time, the hammer head 4 will rebound upward after driving the pile. At this time, the electric cylinder 7 starts to work downward and drives the spring damper 5 downward through the mounting plate 6. When the spring damper 5 is in contact with the fixed plate 3, the rebound of the hammer head 4 will drive the fixed plate 3 to move upward and squeeze the spring damper 5. At this time, the interaction between the spring damper 5 and the electric cylinder 7 will buffer the fixed plate 3 and the hammer head 4, thereby reducing the shock when the hammer head 4 rebounds.
