The utility model provides a robotic arm drives sliding seat 220 through thrust unit and moves on axostylus axostyle 200, and sliding seat 220 drives bracing piece 300 motion at the motion in-process, and bracing piece 300 changes to vertical state by the tilt state, and the washing radius of cleaning head 100 changes, can be at the washing sleeve pipe in-process, adapts to the change of sleeve pipe diameter.

Specifically, when the robot arm extends and adjusts, the pushing device pushes the sliding seat 220 to move toward the fixing seat 210, so as to drive the stay bar 300 to change from the inclined state to the vertical state, and the cleaning head 100 changes along with the movement. When the mechanical arm is contracted and adjusted, the sliding seat 220 moves away from the fixed seat 210 to drive the stay bar 300 to change from a vertical state to an inclined state, so that the change of the pipe diameter of the sleeve can be adapted to in the process of cleaning the sleeve. Wherein, the pushing device can adopt a driving device with a telescopic rod.

As shown in fig. 2 to 4, the cleaning head 100 includes a base 110, a mounting seat 120 and a quick plug 130, the base 110 includes a bottom plate 111 and two ends of the bottom plate 111 are provided with fixing mounting plates 112 extending upwards, the fixing mounting plates 112 are provided with pin holes 1121 penetrating through the plate surface, the two fixing mounting plates 112 and the bottom plate 111 enclose a mounting groove, the upper surface of the mounting seat 120 is covered with a wiping member 140 and is mounted and fixed by fixing members, the mounting seat 120 is mounted in the mounting groove, two ends of the mounting seat 120 are provided with connecting holes 121 corresponding to the pin holes 1121, and the quick plug 130 passes through the pin holes 121 and is fixedly inserted in the connecting holes 121, so as to mount the mounting seat 120 and the base 110 together.

Specifically, after the cleaning head 100 cleans the inner wall of the casing for a period of time, the surface of the wiper 140 becomes dirty, and needs to be replaced in order to ensure the cleaning quality. When the cleaning head device is replaced, the quick bolt 130 is pulled out, the base 110 is separated from the mounting seat 120, the mounting seat 120 is taken out of the mounting groove, then a new mounting seat 120 is installed in the mounting groove, and the quick bolt 130 is inserted, so that the replacement of the cleaning head device is completed. The replacement is convenient and fast, and the cleaning efficiency is improved.

In some embodiments of the present invention, the cross-section of the wiping member 140 is arched, the fixing member includes two fixing plates 150, the fixing plates 150 are provided with mounting holes 151, and the connecting nut 160 passes through the mounting holes 151 to clamp the two fixing plates 150 on two sides of the wiping member 140.

The wiper 140 has an arcuate shape, and is covered on the mounting seat 120, and the wiper 140 is clamped on the mounting seat 120 by providing fixing plates 150 at both sides. Specifically, when the wiping member 140 is assembled with the mounting seat 120, the wiping member 140 is covered on the mounting seat 120, then the two fixing plates 150 are respectively disposed on two sides of the wiping member 140, and then the two fixing plates 150 are connected together through the connecting nut 160, so that the wiping member 140 is clamped on the mounting seat 120, and the operation is reversed when the wiping member 140 is disassembled from the mounting seat 120.

In a further embodiment of the present invention, the coupling nut 160 is a wing nut. The coupling nut 160 is a wing nut, which is convenient to be screwed by hand when the wiper 140 is assembled with the mounting seat 120, and needs little other tools, thereby improving the convenience of replacement.

In some embodiments of the present invention, the wiper 140 is a soft liner. Such as a sponge backing or the like. When the inner wall of the sleeve is cleaned, the supporting rod 300 applies a certain pressure to the wiping part 140, so that the wiping part 140 is tightly attached to the inner wall of the sleeve, and the wiping effect is better. The wiping piece 140 is made of soft lining, and can deform to a certain extent when being pressed, so that the wiping piece is tightly attached to the inner wall of the sleeve, and the wiping effect is better.
