Extending out a piston rod of the lifting cylinder 423 to enable the two working arms to be in a lifting state; the vertical feed mechanism runs down and the end cleaning device 500 is mounted at both ends of the two working arms.

The vertical feeding mechanism runs downwards until the whole equipment enters the storage tank, the piston rod of the lifting cylinder is controlled to be retracted, the two working arms are slowly put down, the micro winch 341 is started, the steel wire rope 342 is tensioned, the positioning arm is lifted to be in a horizontal state, and the central pipe 330 is positioned at the central axis position of the cement storage tank 600.

The vertical feed guide 240 is raised to the uppermost position and starts to operate.

II, cleaning:

the piston rod of the telescopic cylinder 425 is extended to make the guide wheel 530 of the end cleaning device 500 abut against the inner wall of the storage tank (the pressure can be controlled by the selection of the air pressure and the cylinder diameter).

The steel wire roller rotates at a high speed to clean the storage tank.

Meanwhile, the gear motor 333 of the swing mechanism 410 drives the large gear 412 to make the swing mechanism 410 drive the working arm to rotate.

The working arm of the swing mechanism 410 is reversed once per rotation (or no reversal is needed by using the gas-electricity integrated slip ring), the piston rod of the telescopic cylinder 425 is retracted by using a standard outsourced part, such as Mobilong), the vertical feeding guide rod 240 is fed downwards for one stroke, and the piston rod of the telescopic cylinder 425 is extended and reset.

(Note: during the downward feeding of the vertical feed guide 240 by one stroke, the telescopic cylinder can be kept still, so that the guide wheel 530 slides downward by one stroke against the inner wall of the storage tank without any problem)

The cleaning is continued, and the cleaning can be automatically carried out through program setting. The cleaning phase ends until the lowermost part of the tank is reached.

After cleaning, the piston rod of the telescopic cylinder 425 retracts; the wire roller stops rotating. (monitoring device can be arranged on the working arm to check the cleaning condition.)

Thirdly, equipment exit stage:

the two working arms are rotated to the position vertical to the positioning arm and stopped; the piston rod of the raising cylinder 423 is extended to bring the two working arms into a raised state (retracted).

After the vertical feeding guide rod 240 rises for a section, the micro-winch 341 is started reversely, and the wire rope 342 is loosened, so that the positioning arm is inclined downwards and falls down.

Vertical feed guide 240 continues to rise, and after end cleaning apparatus 500 is moved out of the tank opening, vertical feed guide 240 pauses, removing end cleaning apparatus 500 from both ends of the two work arms.

The vertical feed guide 240 is further raised, the positioning arm and the two working arms are fixed by a rope, and the support rod 320 of the positioning arm pitching mechanism 300 is detached from the lower end of the feed guide 240 and then is moved out of the tank opening.

And the vertical feeding guide rod 240 is moved out, the rack 110 is disassembled, and the work is finished.

The device has the following advantages: the mechanical equipment for cleaning the cement storage tank has a relatively simple structure; the cleaning control is simple and does not need complex electrical control. By using the mechanical equipment for cleaning the cement storage tank, continuous cleaning can be carried out in the cleaning stage without interruption.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
