Background technology
Rigidity body refuse rifle is a kind of specific purpose tool that is used for cleaning steam generator secondary side tube sheet upper surface body refuse.Body refuse rifle rifle body is injected High-Pressure Water in the tube bank from middle piping lane, rotation and step motion by the rifle body, High-Pressure Water is injected between each pipe successively, current mechanical energy smashes slime layer, make body refuse water rush at the ring corridor, and under the effect of water suction system, extract body refuse water out steam generator, sludge filtration is collected, thereby reached the purpose of cleaning.
Each nuclear power advanced country has successively developed rigidity body refuse flushing device.The flushing device of France SRA cleaning company development is used in Daya Bay nuclear power plant, and the body refuse rifle utilizes the support of steam generator assignment of traffic baffle plate as rifle body motion guide rail, can guarantee that jet squeezes between pipe, promptly guarantees the jet precision.The equipment integral complexity, the installment work task is heavy, and operating personnel's technical ability is had relatively high expectations.
Qinshan first phase nuclear power plant introduces rigidity body refuse flushing device from Germany former ABBR company, and the jet precision of rifle body guarantees by the mechanical precision of self and steam generator hand hole, to having relatively high expectations of installation personnel, needs to carry out precision adjustment and correction in the course of work.
Can the high-pressure spray water of body refuse rifle be squeezed between the heat-transfer pipe pipe, is the principal element that influences developing result.Therefore, must guarantee the bearing accuracy of rifle body at steam generator center piping lane.
Summary of the invention
The purpose of this utility model is to provide a kind of versatility height, stable and reliable for performance, fitting operation convenience, small investment, heat-transfer pipe square arrangement steam generator rigidity body refuse rifle that kinematic accuracy is high.
The technical solution of the utility model is as follows:
A kind of be used for the body refuse rifle to middle regulator, it comprises sleeve, the sleeve two ends are respectively equipped with back up pad a and back up pad b, be fixed with support bar between back up pad a and the back up pad b, described back up pad a and back up pad b center are respectively equipped with circular hole, have the screw hole that communicates with circular hole on four sides on the plate face direction of back up pad a and back up pad b, be respectively equipped with screw a, screw b, screw c and screw d in the hole.
Above-mentioned be used for the body refuse rifle to middle regulator, the outer wall of described sleeve is provided with spherical blind hole, screw a, screw b, screw c and screw d are sphere screw, and extend into respectively in the corresponding blind hole.
Above-mentioned be used for the body refuse rifle to middle regulator, the external diameter of sleeve leaves the gap less than the diameter that back up pad a and back up pad b go up center pit between sleeve outer wall and the circular hole.
Advantage of the present utility model is: sleeve, the design of back up pad and support bar has at first guaranteed the initial installing and locating precision of body refuse rifle, by adjusting the design of blind hole on screw and the sleeve outer wall on the back up pad, realized the centering adjusting of body refuse rifle, can reduce the manufacturing accuracy of body refuse rifle mounting flange, the body refuse rifle is carried out vertically and the adjusting of the location on the horizontal direction, make the body refuse rifle not need in the course of the work further to position and adjust and correct, thereby reduce the installation difficulty of equipment, can guarantee that simultaneously water jets squeezes between the heat-transfer pipe pipe, guarantee to clean impact effect.This apparatus structure is simple, and is easy to operate.
