Description

Technical Field

[0001] The utility model relates to the technical field of pile hammers, in particular to a noise-reducing hydraulic pile hammer. Background Art

[0002] The pile driver consists of a pile hammer, a pile frame and auxiliary equipment. The pile hammer is attached between two parallel vertical guide rods at the front of the pile frame and is lifted by a lifting hook. The pile frame is a steel structure tower with a winch at the rear to lift the pile and the pile hammer. There is a guide frame composed of two guide rods in front of the pile frame to control the direction of piling so that the pile can be accurately penetrated into the formation according to the designed direction. The basic technical parameters of the pile driver are the weight of the impact part, the impact kinetic energy and the impact frequency. The pile hammer can be divided into a drop hammer, a steam hammer, a diesel hammer, a hydraulic hammer, etc. according to the power source of the movement.

[0003] When using a hydraulic pile hammer, a hydraulic cylinder is used to convert high-pressure oil into mechanical energy, and the pile body is impacted by the hammer head, thereby driving the pile body into the ground.

[0004] After searching, the Chinese utility model patent with publication number: CN209555920U discloses a noise-reducing hydraulic pile hammer, including a side base, an intermediate base is arranged between the side bases, a first slide is welded on the top of the side base, a second slide is welded on the top of the intermediate base, a first walking mechanism is slidably mounted on the first slide, a second walking mechanism is slidably mounted on the second slide, the tops of the first walking mechanism and the second walking mechanism are welded to each other through a platform, a swivel is welded on the right side of the top of the platform, a suspension arm is rotatably mounted on the swivel, a diagonal support cylinder is welded on the left side of the top of the platform, and one side of the suspension arm is connected to the free end of the diagonal support cylinder.

[0024] A positioning block 15 is provided inside the positioning box 13, and fixing grooves 17 are evenly provided on the surface of the positioning block 15. A button 16 is provided inside one side of the positioning box 13. The button 16 is located at one end of the positioning box 13 and is fixedly connected to a fixing block 18. A first spring 19 is provided between the fixing block 18 and the inner wall of the positioning box 13, and a second spring 20 is provided between the top of the positioning block 15 and the inner wall of the positioning box 13. The button 16 can control the cooperation between the fixing block 18 and the fixing groove 17, so that the positioning block 15 is fixed in the positioning box 13 by using the button 16. When the fixing block 18 and the fixing groove 17 are no longer matched, the positioning block 15 will be ejected by the elastic force of the second spring 20, so that the positioning block 15 is fixed at the pile position, which is convenient for controlling the distance between the piles.

[0025] The top of the base 1 is fixedly connected to a support 2, the top of the support 2 is fixedly connected to a top seat 3, one end of the top seat 3 is provided with a control panel 4, the control panel 4 can control the hydraulic oil to be discharged from or flow back from the hydraulic oil tank 9, so as to control the hydraulic cylinder 5 with the hydraulic oil.

[0026] A hydraulic cylinder 5 is arranged inside the top seat 3, and a pile hammer connecting plate 6 is fixedly connected to the bottom end of the hydraulic cylinder 5, and a rubber pile hammer 7 is fixedly connected to the bottom end of the pile hammer connecting plate 6. The pile hammer connecting plate 6 can quickly replace the pile hammer when the pile hammer is damaged to ensure work efficiency, and the rubber pile hammer 7 can play a role in shock absorption and noise absorption, thereby reducing vibration and noise during work.

[0027] A hydraulic oil tank 9 is provided on one side of the base 1, and a hydraulic oil pipe 10 is movably connected to the top of the hydraulic oil tank 9. The other end of the hydraulic oil pipe 10 is movably connected to the top of the hydraulic cylinder 5. The hydraulic oil pipe 10 can transport the hydraulic oil in the hydraulic oil tank 9 to the hydraulic cylinder 5, making it convenient for the hydraulic cylinder 5 to drive the pile hammer for piling.

After the first pile is driven, the device is removed, and the button 16 of the positioning box 13 is pressed. Under the action of the first spring 19, the fixing block 18 and the fixing groove 17 are cancelled. At the same time, the positioning plug 15 will pop out from the positioning box 13 under the action of the second spring 20, and then the positioning plug 15 will be inserted into the ground. After the positioning plug 15 is inserted into the ground, the device is moved. While the device is moving, the extension tube 12 and the extension rod 11 will extend, and then the measuring ruler 14 will also extend. The extended length is read using the measuring ruler 14. When the reading of the measuring ruler 14 is the same as the distance of the pile position, the device can be stopped and the pile can be driven again. This reciprocating process can drive the pile well and ensure that the distance between the piles is the same, which brings convenience to subsequent work.
