Description
The utility model relates to a kind of fixed three-dimensional space walk mechanism that aims at thermal power plant steam turbine condenser copper tubes on-line cleaning and design.
Though existing steam turbine of thermal power plant condenser copper tubes ball cleaning apparatus energy on-line operation, but exist optional equipment many, the piping complexity, equipment investment is big, cleaning efficiency is low, have opportunistic in the ball inlet pipe, ball collecting rate is low, can not be automatic, operation sequence is many, and want problems such as execute-in-place, overall consuming cost height, make most of user normally not come into operation.
The purpose of this utility model just provides a kind of fixed three-dimensional space walk mechanism, as steam turbine of thermal power plant condenser steel pipe on-line cleaning device, can replace ball cleaning apparatus and artificial the cleaning, it is little to have volume, cost is low, efficient height, automaticity height, walking is flexible, the contraposition characteristic of accurate.
The technical solution of the utility model is: be made of running gear and cleaning device, break-in transmission slide bar wherein driven by stepper motors connects with horizontal lead screw by the engagement of a pair of bevel gear, on horizontal lead screw, be equipped with and move horizontally nut, move horizontally the cleaning device that is equipped with on the nut by the control of bidirectional hydraulic oil cylinder, the other end of horizontal lead screw is contained on the oscilaltion nut by bearing, the oscilaltion nut then is contained in and driven by stepper motorsly transmits on the screw mandrel up and down, bevel gear on the break-in transmission slide bar adopts feather key to connect, its below is the lifting fairlead, the lifting fairlead then be contained in the assistance for lifting nut that transmits up and down on the screw mandrel and connect, transmit screw mandrel up and down and drive by stepper motor.
According to technique scheme, stepper motor work drives respectively and transmits screw mandrel and the rotation of break-in transmission slide bar, a pair of bevel gear of rotating drive of break-in transmission slide bar up and down, to the greatest extent and horizontal lead screw is rotated, on the horizontal lead screw move horizontally nut just can be on horizontal lead screw move left and right.The rotation of transmitting screw mandrel up and down drives the oscilaltion nut respectively and the assistance for lifting nut moves up and down, and by a pair of bevel gear horizontal lead screw is moved up and down.To move horizontally cleaning device on the nut be by the control of bidirectional hydraulic oil cylinder owing to be contained in horizontal lead screw, promptly can realize moving forward and backward, so cleaning device promptly can be walked in three dimensions.
Cleaning device of the present utility model is to be made of spray gun, spray gun is connected on the piston of bidirectional hydraulic oil cylinder, and the spray gun high-pressure hose is housed, piston seesaws in-oil cylinder, can be so that spray gun to be done same motion, water under high pressure is come out just can carry out cleaning by lance ejection through the spray gun high-pressure hose.
The utility model all is with retractable guard transmitting up and down on screw mandrel, break-in transmission slide bar and the horizontal lead screw; when top movement parts moves back and forth; retractable guard promptly can stretch; do not influence the motion of movement parts; can protect again simultaneously and transmit screw mandrel up and down; break-in transmission slide bar and horizontal lead screw are not subjected to etch, prolong its service life.
The fixed three-dimensional space walk mechanism that the utility model provides is owing to adopt stepper motor to drive walking mechanism, accurate positioning, error free accumulation, the periphery can reach full automatic purpose by computer control, adopts screw rod, nut and slide bar, bevel gear transmission, simple in structure, manufacturing process is simple, and stable drive.Therefore, the utility model can replace virgin rubber ball cleaning device and artificial the cleaning, and it is little to have a volume, and cost is low, and the efficient height is installed simply, easy to maintenance, and province's effect that can lower consumption is remarkable, also has deft design simultaneously, and simple in structure, walking is sensitive, the contraposition characteristic of accurate.Also can be used for the cleaning of the heat exchanger of other type.
