Swing spray gun and water jet equipment

Abstract

The invention provides a swing spray gun and water jet equipment. The swing spray gun comprises a base, a bearing seat, a jet pipe and a third driving device, wherein the bearing seat is driven by a second driving device to rotate around a first axis relative to the base; the jet pipe is rotatably mounted on the bearing seat around a second axis, the top end of the jet pipe is connected with a high-pressure water source, and a nozzle located at the bottom of the jet pipe faces the layer to be treated; and third driving device is installed on the bearing seat, an eccentric structure is arrangedon an output shaft parallel to the second axis, an eccentric protrusion of the eccentric structure is hinged to a connecting rod, the other end of the connecting rod is hinged to the jet pipe, and the hinged position and the second axis position are arranged at intervals by a set distance to form a crank-rocker mechanism. According to the design, swing amplitude of the nozzle can be increased firstly, and then the working efficiency of the jet pipe during a single stroke can be increased; secondly, the same swing amplitude requires less driving force and prolongs the service life of the thirddriving device; and in addition, an injection pipe returns to the initial position in the non-working state without shaking, and the performance and reliability of the device are ensured.

Description

technical field [0001] The invention relates to the technical field of material removal equipment, in particular to an oscillating spray gun, and at the same time relates to a water jet equipment. Background technique [0002] The concrete layer on the pavement or bridge will be damaged by fatigue after long-term use, and the damaged part should be repaired or reconstructed in time. The current treatment method is to first destroy the pavement layer in the target area, and then renovate and pave according to the original pavement structure. The commonly used pavement destruction method is to use an excavator equipped with a hydraulic breaker to forcefully destroy the pavement structure. The disadvantage is that the pavement layer is also destroyed while the steel layer is broken, and the breaker produces a large noise when it is working. And more dust, seriously affecting the normal life of the surrounding residents. [0003] With the country's higher and higher requiremen...
