Description

Cleaning machine

Technical Field

The utility model relates to the field of tank cleaning, in particular to a cleaning machine.

Background

The tank body commonly used in industry comprises a reaction kettle, a liquid storage tank, a fermentation tank and the like in the chemical industry field. The inner walls of these tanks need to be cleaned. If the cleaning is carried out manually, time and labor are wasted. Automatic cleaning machines have therefore emerged in the prior art. As shown in fig. 1, the cleaning machine in the prior art includes a hose transfer device 101, a tilting arm device 102, a lifting device 103, and a coil device 104.

Taking a vertical tank as an example, the method for cleaning the tank body by using the cleaning machine comprises the following steps: firstly, placing a cleaning machine near an opening at the top of a tank body (in a manual cleaning mode, cleaning staff can enter the inside of the tank body through the opening); then the lifting device 103 acts, and the arm raising device 102 descends along with the lifting device 103 and enters the tank body; the free end of the hose at the lower end of the arm tilting device 102 is provided with a nozzle, and the nozzle sprays cleaning medium, so that the cleaning of the inner wall of the tank body can be realized.

The arm raising device 102 can swing, so that the positions of the lower end and the nozzle are changed, and cleaning of different parts is realized. A hose with a certain length is wound in the coil pipe device 104, and the length of the hose entering the tank body can be changed through the traction of the hose conveying device 101 and the guidance of the arm tilting device 102; that is, the free end of the hose can be varied in height within the canister to effect cleaning of different height locations; when the coil pipe device 104 is put into the tube, the length of the hose entering the tank body is increased, and the height of the free end of the hose is reduced; when the coil assembly 104 is retracted, the length of the hose entering the tank is reduced and the free end of the hose rises in height.

The existing lifting device 103 has the problems that a motor driving and chain wheel and chain transmission structure is adopted; the limit signal is generated by using a sensor such as a travel switch or a proximity switch, so that the motor is controlled to stop. The working process of the existing lifting device 103 is as follows: the motor drives the chain wheel, the chain wheel drives the chain, the object to be lifted is connected to the chain, and the object to be lifted is lifted or lowered under the driving of the chain; when the motor is lifted or lowered into place, the sensor senses a bit signal and generates a limit signal to be sent to the controller, and then the controller controls the motor to stop. Any link error can cause the motor to stop failure, so that the situation of 'collision machine' occurs and danger is generated. The possible reasons for the collision are that the sensor fails, a limit signal generated by the sensor cannot be transmitted to the controller, the controller goes wrong, a control signal of the controller cannot be transmitted to the motor, and the like.

The first-stage moving body 301 is connected to the fixed body 303 and can move linearly with respect to the fixed body 303. The push rod 304 is connected to the primary moving body 301 and is capable of driving the primary moving body 301 to move in the direction indicated by the double-headed arrow M. The secondary moving body 302 is connected to the primary moving body 301 and is capable of moving linearly with respect to the primary moving body 301, and the secondary moving body 302 and the primary moving body 301 are parallel to each other in the moving direction.

In fig. 4 and 5, hatching-like hatching is used to clearly distinguish the fixed body 303, the primary moving body 301, and the secondary moving body 302; these shadows are only used to distinguish between different components, and do not represent cross sections or the material of the components.

Second embodiment

In accordance with the first embodiment, the present embodiment provides a way to drive the secondary moving body 302, that is, when the primary moving body 301 moves relative to the fixed body 303, the secondary moving body 302 is simultaneously driven to move relative to the primary moving body 301. As shown in fig. 6 and 7, in the present embodiment, a first-stage moving body 301 has a rotating wheel 306, and a rope 307 that bypasses the rotating wheel 306 is connected to a fixed body or an external base 308 at one end and to a second-stage moving body 302 at the other end; when the primary moving body 301 moves relative to the fixed body, the secondary moving body 302 moves relative to the primary moving body 301 by the pulling action of the string 307.

In the present embodiment, in the process of moving the primary moving body 301 and the fixed body 303 relatively, the primary moving body 301 may drive the secondary moving body 302 to move relatively to the primary moving body 301 through the rotating wheel 306 and the rope 307 at the same time; it is also understood that the primary moving body 301 is capable of transmitting the driving force of the push rod 304 to the secondary moving body 302, so that the secondary moving body 302 moves relative to the primary moving body 301; it will also be appreciated that the push rod 304 "directly drives" the primary mover 301 relative to the stationary body 303 and "indirectly drives" the secondary mover 302 relative to the primary mover 301.

Fig. 6 and 7 show how the primary mover 301 moves the secondary mover 302 via the wheel 306 and the belt 307. Fig. 6 can be seen as a left side view of fig. 4, which shows a state in which the secondary moving body 302 is located at the upper limit, when the upper end of the push rod 304 is pushed out to the uppermost end of its stroke; fig. 7 can be seen in the left side view of fig. 5, which shows the state where the secondary moving body 302 is located at the lower limit, with the upper end of the push rod 304 retracted to the lowermost end of its stroke. For the sake of clarity of illustration, fig. 6 and 7 use simplified drawings, and the fixing body 303 and the push rod 304 are omitted; the secondary moving body 302 is not visible behind the primary moving body 301, and is therefore indicated by a broken line. For clarity of illustration of the lifting movement of the primary mover 301, fig. 6 and 7 show a datum 309, which may be considered as the bottom surface of the stationary body 303.

The primary moving body 301 drives the secondary moving body 302 to move through the rotating wheel 306 and the rope 307 as follows: when the lifting device is in the upper limit state shown in fig. 4 and 6, the push rod drives the primary moving body 301 to descend, so that the secondary moving body 302 moves downwards under the traction of the rope 307 and under the action of its own weight, and finally reaches the lower limit state shown in fig. 5 and 7; when the lifting device is in the lower limit state shown in fig. 5 and 7, the push rod drives the primary moving body 301 to rise, and the secondary moving body 302 moves upward under the upward tension of the string 307, and finally reaches the upper limit state shown in fig. 4 and 6. The lower limit state shown in fig. 5 and 7 corresponds to the arm lifting device 202 being lowered and entering the tank to be cleaned; the upper limit condition shown in fig. 4 and 6 corresponds to the arm lifting device 202 being lifted out of the can.

As an example of this embodiment, the wheel 306 may be a sprocket and the belt 307 may be a chain. As another example of this embodiment, the wheel 306 may also be a pulley and the belt 307 may be a rope; the rope may be a steel wire rope made of metal or a rope made of nonmetal.
