Abstract
An articulating water monitor-cleaning device for cleaning internal surfaces of large-scale combustion devices. The device is mounted to the exterior of a wall of a combustion device and positions a water spray lance to direct a stream of water against internal surfaces over a range of position. Pairs of orthogonally oriented four-bar linkage assemblies are provided, each having rotary actuators. The relative position between a pair of joints affixed to the lance tube allows the position of the lance to be set over a range of positions.
Claims22
An articulating monitor cleaning device for projecting a stream of a fluid into a combustion device having an interior volume and an exterior wall with a wall port through said exterior wall, said device comprising:
- a lance tube adapted to receive said fluid and eject said fluid into said interior volume;
- a first articulating joint coupled to said lance tube at a first position adjacent said nozzle adjacent said wall port;
- a second articulating joint coupled to said lance tube at a second position displaced from said first position;
- a horizontal motion actuator assembly including an actuated horizontal motion four-bar linkage coupled with said second articulating joint for causing said second articulating joint to be displaceable horizontally with respect to said first articulating joint;
- and
- a vertical motion actuator assembly including an actuated vertical motion four-bar linkage coupled with said second articulating joint for causing said second articulating joint to be displaceable vertically with respect to said first articulating joint, whereby coordinated actuation of said horizontal motion actuator assembly and said vertical motion actuator assembly enables a range of angular positions of said lance tube to be set such that the direction of discharge of said fluid into said combustion device may be controlled.
An articulating monitor cleaning device for projecting a stream of a fluid into a combustion device having an interior volume and an exterior wall with a wall port through said exterior wall, said device comprising:
- a lance tube adapted to receive said fluid and having a nozzle for ejecting said fluid into said interior volume;
- a first articulating joint coupled to said lance tube at a first position adjacent said nozzle and mounted adjacent said wall port;
- a second articulating joint coupled to said lance tube at a second position displaced from said first position;
- a horizontal motion actuator assembly including an actuated horizontal motion four-bar linkage coupled with said second articulating joint and a horizontal motion rotary actuator coupled with said horizontal motion four-bar linkage for causing said second articulating joint to be displaceable horizontally with respect to said first articulating joint;
- said horizontal motion actuator assembly further including a non-actuated horizontal motion four-bar linkage coupled with said second articulating joint and acting in parallel with said actuated horizontal motion four-bar linkage,
- a vertical motion actuator assembly including an actuated vertical motion four-bar linkage coupled with said second articulating joint and an a vertical motion rotary actuator coupled with said vertical motion four-bar linkage for causing said second articulating joint to be displaceable vertically with respect to said first articulating joint, said vertical motion actuator assembly further including a non-actuated vertical motion four-bar linkage coupled with said second articulating joint and acting in parallel with said actuated vertical motion four-bar linkage, whereby coordinated actuation of said horizontal motion actuator assembly and said vertical motion actuator assembly enables a range of angular positions of said lance tube to be set such that the direction of discharge of said fluid into said combustion device may be controlled.
An articulating monitor cleaning device for projecting a stream of a fluid into a combustion device having an interior volume and an exterior wall with a wall port through said exterior wall, said device comprising:
- a seal box assembly mounted to said boiler wall and forming said wall port,
- a mounting plate adapted to be mounted to said seal box assembly,
- fasteners for affixing said mounting plate assembly to said seal box assembly,
- a lance tube adapted to receive said fluid and having a nozzle for ejecting said fluid into said interior volume;
- a first articulating joint coupled to said lance tube at a first position adjacent said nozzle and mounted to said mounting plate assembly adjacent said wall port;
- a second articulating joint coupled to said lance tube at a second position displaced from said first position;
- a horizontal motion actuator assembly mounted to said mounting plate assembly for causing said second articulating joint to be displaceable horizontally with respect to said first articulating joint;
- and
- a vertical motion actuator assembly mounted to said mounting plate assembly for causing said second articulating joint to be displaceable vertically with respect to said first articulating joint, whereby coordinated actuation of said horizontal motion actuator assembly and said vertical motion actuator assembly enables a range of angular positions of said lance tube to be set such that the direction of discharge of said fluid into said combustion device may be controlled.
