Description

Technical Field

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

[0002] Vibratory pile drivers are widely used in civil engineering construction. Pile drivers use their own impact or vibration impact force to drive piles into the ground. Commonly used pile drivers include drop hammer pile drivers, steam hammer pile drivers, diesel hammer pile drivers, hydraulic hammer pile drivers, and spiral pile drivers.

[0003] According to a vibrating pile driver described in patent number CN212316922U, the up and down movement of the internal vibrating end during use may cause leakage of lubricating oil. After long-term use, the internal lubricating oil is lost, which may easily lead to increased internal wear and reduce the service life of the equipment. Utility Model Content

The oil is injected into the main body of the piling mechanism for replenishment. After it starts to be used, the vibrating end of the piling mechanism main body vibrates, driving the sealing squeeze ball to move up and down, exposing the oil discharge port, and then transporting the oil downward to the piling mechanism main body for replenishment of the lubricating oil, which can effectively prevent the lubricating oil from being insufficient and causing wear inside the piling mechanism main body, and the sealing squeeze ball can be limited by the elastic pull rope to prevent it from moving beyond the range of the oil injection pipeline, and when the processing stops, the sealing squeeze ball automatically resets to seal the lubricating oil. No additional operation is required, only oil injection is required to automatically open and close in conjunction with the work of the piling mechanism main body, which is more convenient to operate, can effectively reduce the wear of the internal mechanical structure, and increase the service life.

[0007] As a further solution of the utility model: when the elastic pull rope is stretched to the limit, the upper half of the sealing extrusion ball is located above the oil injection pipe, which can prevent the sealing extrusion ball from falling off and causing failure to open and close normally.

[0008] As a further solution of the utility model: the ball sleeve is a semicircular ball sleeve with the same diameter as the sealing extrusion ball, which can better adapt the ball sleeve.

[0009] As a further solution of the utility model: the recovery mechanism includes an oil retaining ring fixed on the surface of the vibrating end of the piling mechanism body and an oil collecting cylinder movably connected to the piling mechanism body through a movable groove, the top of the oil collecting cylinder is fixedly connected with a threaded connecting section, the inner cavity of the movable groove is fixedly connected with a connecting cylinder threadedly connected to the threaded connecting section, and the bottom of the oil retaining ring is connected with a recovery pipe connected with the connecting cylinder. When in use, when the vibrating end of the piling mechanism body moves up and down, the internal oil will slide out and drip along the surface to the top of the oil collecting cylinder. After being blocked by the oil collecting cylinder, it will be transported along the recovery pipe to the connecting cylinder, and then fall into the oil collecting cylinder for collection. After a certain amount is collected, the oil collecting cylinder is unscrewed and the lubricating oil filtered by the filter is poured back into the oil filling tank for recycling, so that the oil can be effectively circulated.

[0010] As a further solution of the utility model: a filter screen is fixedly connected to the bottom of the connecting cylinder, and the lubricating oil is filtered through the filter screen to prevent iron filings and impurities from entering the oil collecting cylinder and being recovered.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The utility model can effectively prevent the internal wear of the piling mechanism body caused by insufficient lubricating oil, and the sealing extrusion ball can be limited by the elastic pull rope to prevent it from moving beyond the range of the oil injection pipeline, and when the processing stops, the sealing extrusion ball automatically resets to seal the lubricating oil. No additional operation is required, and the piling mechanism body can be automatically opened and closed by simply injecting oil. The operation is more convenient, and the wear of the internal mechanical structure can be effectively reduced, thereby increasing the service life.

[0013] 2. When the utility model is in use, when the vibrating end of the piling mechanism body moves up and down, the internal oil will slide out and drip along the surface to the top of the oil collecting cylinder.
