Description

Anti-degassing dynamic chuck for flushing steel pipe Technical Field The utility model relates to the field of cleaning equipment, in particular to an anti-degassing dynamic chuck for steel pipe flushing. Background In the process of cleaning the steel pipe, not only the outer wall of the steel pipe but also the inner wall of the steel pipe is cleaned. Part of the steel pipes are up to several meters in length, and the steel pipes are directly placed into the cleaning pool, so that the inner walls of the steel pipes are difficult to clean efficiently, and water flow is required to be led into the steel pipes, so that the inner walls of the steel pipes are flushed. In order to ensure the cleaning effect, the impact force of water flow is relatively large, and if only the water pipe connector is inserted into one end of the steel pipe, the steel pipe is easy to loosen under the impact of the water flow, so that the normal cleaning flow is influenced, and improvement is needed. Disclosure of utility model The utility model mainly solves the technical problem of providing the anti-degassing movable chuck for steel pipe flushing, which realizes quick clamping and fixing during steel pipe flushing and avoids the problem of loosening. In order to solve the technical problems, the technical scheme includes that the anti-degassing dynamic chuck for flushing the steel pipe comprises a base, a piston, a pressing ring and an elastic sealing sleeve, wherein a first guide hole corresponding to the pressing ring is concavely formed in the front face of the base, a mounting hole corresponding to the elastic sealing sleeve is concentrically formed in the bottom of the first guide hole, the elastic sealing sleeve is arranged in the mounting hole, the front end of the elastic sealing sleeve extends into the first guide hole, the pressing ring is arranged in the first guide hole and is in contact with the front end of the elastic sealing sleeve, the bottom of the first guide hole is axially provided with a piston hole located on one side or two sides of the mounting hole, the piston is arranged in the piston hole, a connecting rod is arranged between the piston and the pressing ring, an air inlet pipe connecting hole which is communicated with the piston hole and vertically points to the connecting rod is arranged on the side face of the base, and a water inlet hole which extends to the back face of the base is concentrically formed in the bottom of the mounting hole. In a preferred embodiment of the present utility model, a threaded hole is provided at the front end of the piston hole, a nut is provided in the threaded hole, a second guiding hole corresponding to the connecting rod is provided in the nut, and a sealing ring is provided in the second guiding hole. In a preferred embodiment of the utility model, the back of the base is provided with a water inlet pipe joint which is connected with the water inlet hole in a threaded mode. In a preferred embodiment of the present utility model, a retainer ring located in front of the pressing ring is disposed in the first guide hole. In a preferred embodiment of the utility model, the retainer ring adopts a snap spring, and the inner wall of the mounting hole is provided with a ring groove corresponding to the retainer ring. In a preferred embodiment of the present utility model, the diameters of the first guide hole, the mounting hole and the water inlet hole are sequentially reduced. In a preferred embodiment of the present utility model, the base side is provided with a vent hole communicating with the end of the piston bore. The anti-degassing dynamic chuck for steel pipe flushing has the beneficial effects that after one end of a steel pipe is inserted into an elastic sealing sleeve, compressed air is fed into a piston hole through an air inlet pipe connected with an air inlet pipe connecting hole to push a piston to move backwards, a connecting rod is used for pulling a pressing ring to move backwards, the elastic sealing sleeve is extruded, elastic deformation of the elastic sealing sleeve towards the outer wall direction of the steel pipe is induced, the connection between the elastic sealing sleeve and the outer wall of the steel pipe is enhanced, and the problem that the steel pipe is loosened with the elastic sealing sleeve in the flushing process is avoided.
