Problems solved by technology

[0003] As we all know: the pendulum valve performs gap and high-frequency cycle action during the working process. The hydraulic cylinder or hydraulic system as the drive bears a large hydraulic shock during the working process. This hydraulic shock will not only cause a large noise in the equipment, What is more serious is that it is easy to reduce the life of the equipment system and damage the equipment. There is no good solution for this at present

Abstract

The invention provides a structure of a swing valve driving oil cylinder of a concrete pump. A plunger is arranged in a cylinder body; a cylinder cover is arranged at the bottom of the cylinder body; a compression spring is arranged in a blind hole formed in the middle of the plunger; a collision block is fixedly mounted at the outer end of the spring; and a collision rod is mounted and fixed in the middle in the cylinder cover through a bolt. According to the invention, impact phenomenon and damages due to the impact phenomenon in the working of the traditional swing valve driving oil cylinder of the concrete pump can be overcome.

Description

technical field [0001] The invention relates to a concrete pump, in particular to the structure of a concrete pump buffer pendulum valve oil cylinder, and belongs to the technical field of concrete pumps. Background technique [0002] The pendulum valve of the concrete pump is driven by the plunger cylinders arranged symmetrically on both sides of the pendulum valve, and the two driving cylinders do similar "push-pull" actions during the working process. [0003] As we all know: the pendulum valve performs gap and high-frequency cycle action during the working process. The hydraulic cylinder or hydraulic system as the drive bears a large hydraulic shock during the working process. This hydraulic shock will not only cause a large noise in the equipment, What is more serious is that it is easy to reduce the life of the equipment system and damage the equipment. To this, there is no good solution at present. Contents of the invention [0004] The purpose of the present ...
