Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a pipeline connector for a hydraulic pile hammer. Background Art

[0002] Pipeline connectors are generally used to connect hoses and hard pipes. They are a kind of mechanical connection mechanism. In hydraulic pile hammers, appropriate pipe connectors are selected according to the working pressure and flow of the hydraulic pile hammer to ensure that the pressure rating and flow requirements of the connectors match the hydraulic system, and to ensure the correctness and safety of the connection of the hydraulic pile hammer pipe connectors, so as to ensure the normal operation and service life of the hydraulic pile hammer.

[0003] For example, the utility model with the authorization announcement number CN205896470U relates to the technical field of pipeline connection, and specifically discloses a pipeline connector, including a pipe seat, a pipe sleeve and a connecting nut. The pipe seat is a copper alloy pipe seat, the pipe sleeve is between the pipe seat and the pipe sleeve, the connecting nut includes a connecting end and a pipe fitting end, the pipe seat and the pipe sleeve are arranged in the pipe fitting end, and the pipe seat is fixed to the pipe sleeve and the connecting nut by expansion and deformation. This connection is accompanied by a disposable punch expansion method, so that the pipe seat is deformed, and the connector is fixed as a whole, which is easy to operate. Since the deformation is irreversible, the pipeline connection is tight and not easy to detach. At the same time, the pipeline is also squeezed and deformed between the pipe seat and the pipe sleeve, which has good sealing performance.

[0004] However, the above technical solution still has some disadvantages. For example, if the pipeline is connected by thread, the pipeline connection will be unstable and easy to fall off. At the same time, if the pipeline connection is only fixed, the pipeline connection will be easily damaged under the action of external force. In addition, the pipeline will swing under the action of external force, and the pipeline connector will swing with the swing of the pipeline, which is prone to wear and other problems. Therefore, we propose a pipeline connector for a hydraulic pile hammer to solve the above problems. Utility Model Content

[0016] As a preferred technical solution of the present utility model, a buckle is fixedly connected to the left side of the spring.

[0017] The above technical solution is adopted by arranging a spring on the right side of the buckle, and by pulling the buckle, the spring will be deformed. When the buckle passes through the hole and is firmly engaged with the slot, the spring will support the buckle, so that the connection between the buckle and the slot will not become loose.
