[0041] Referring to Figures 1-5 The utility model provides a walking drive mechanism for cleaning the inner wall of a mixer, comprising a crossbeam 100, the crossbeam 100 is erected outside a rotary kiln 200, and the crossbeam 100 extends into the rotary kiln 200, a cleaning member 300 is movably arranged on the crossbeam 100, the moving direction of the cleaning member 300 is parallel to the axis of the rotary kiln 200, and the cleaning member 300 is used for cleaning the residues on the inner wall of the rotary kiln 200, two winches 400 are arranged on the two sides of the crossbeam 100 respectively, and the two winches 400 are used for pulling the cleaning member 300 to move, and the two winches 400 rotate synchronously and in opposite directions.

[0042] In this embodiment, the crossbeam 100 is made of a material that is strong, durable and resistant to high temperatures, and is stably erected outside the rotary kiln 200 through a suitable support structure and extends into the kiln, and the crossbeam 100 does not come into contact with the inner wall of the rotary kiln 200. The cleaning member 300 is installed on the crossbeam 100 through a pulley, a slide rail or other guiding device and can smoothly move along the length direction of the crossbeam 100 (i.e., the direction parallel to the axis of the rotary kiln 200). Two winches 400 are respectively installed on the two sides of the crossbeam 100 and are synchronously rotated through a control system and in opposite directions. When the cleaning member 300 needs to be moved, the two winches 400 work simultaneously, one winch winds the rope and the other winch unwinds the rope, thereby pulling the cleaning member 300 to move along the crossbeam 100.

[0043] During the operation of the rotary kiln 200, since the rotary kiln 200 also rotates by itself, the reciprocating movement of the cleaning member 300 in combination with the rotation of the rotary kiln 200 can comprehensively and efficiently clean the inner wall of the rotary kiln 200. The synchronous winding and unwinding of the two winches 400 ensures that the traction rope between the winches 400 and the cleaning member 300 is always in a tension state. In this way, not only can the residues be prevented from falling onto the traction rope and solidifying, the traction rope can be prevented from adhering to the crossbeam 100, the load of the winch 400 can be reduced, the service life of the winch 400 can be prolonged, but also the unnecessary wear of the traction rope due to slackening can be reduced, and the service life of the traction rope can be prolonged.

[0044] The cooperative work of the two winches 400 and the cooperation with the rotation of the rotary kiln 200 greatly improve the cleaning effect and efficiency and ensure the cleanliness of the inner wall of the rotary kiln 200. The traction rope is always kept in a tension state, which effectively reduces the damage risk of the winch 400 and the traction rope and reduces the cost of equipment maintenance and replacement.

[0045] Further, the winch 400 includes a frame 410, the frame 410 is arranged on one side of the crossbeam 100; a reel 420 is rotatably arranged on the frame 410, the reel 420 is used for winding the traction rope, and the reel 420 has a spiral groove 421 for guiding the traction rope.

[0046] In this embodiment, the frame 410 is firmly arranged on one side of the crossbeam 100 by welding, bolt connection or the like. The reel 420 is rotatably mounted on the frame 410 and can smoothly rotate. The surface of the reel 420 is processed with the spiral groove 421, and the shape and size of the spiral groove 421 are matched with the traction rope.

[0047] When the winch 400 works, the reel 420 rotates, and the traction rope is orderly wound on the reel 420 along the spiral groove 421, which avoids the traction rope from being disordered or crossed during winding, and ensures the stable operation of the cleaning member 300.

[0048] Further, the winch 400 further comprises a first rotating driving device 430, which is arranged on the frame body 410 and used to drive the reel 420 to rotate.

[0049] In this embodiment, the servo motor as the first rotating driving device 430 is mounted on the frame body 410 by means of bolt fastening or the like. The output shaft of the servo motor is tightly connected with the reel 420 through a shaft coupling. In operation, the servo motor receives accurate control signals and can realize high-precision speed and steering control, thereby accurately driving the reel 420 to perform winding or unwinding actions.

[0050] The use of the servo motor as the first rotating driving device 430 can provide accurate control, ensure the rotation speed and position accuracy of the reel 420, and guarantee the stable operation of the cleaning member 300 and the stable tension of the traction rope. The servo motor has the characteristics of fast response speed and high control precision, can quickly adapt to different working conditions and load changes, and ensures the high efficiency and stability of the cleaning work.

[0051] Further, a limiting ring 500 is arranged on the frame body 410 in a sliding manner, the sliding direction of the limiting ring 500 is parallel to the axis direction of the reel 420, the limiting ring 500 is located between the reel 420 and the cleaning member 300, and the traction rope passes through the limiting ring 500.

[0052] In this embodiment, the limiting ring 500 is mounted on the frame body 410 through a sliding rail or other sliding structure and can smoothly slide along a direction parallel to the axis of the reel 420. The limiting ring 500 is located at a suitable position between the reel 420 and the cleaning member 300, and the traction rope passes therethrough.

[0053] During the operation of the winch 400, with the winding and unwinding of the reel 420, the limiting ring 500 will automatically slide and adjust the position according to the position and tension of the traction rope, so as to limit the swing range of the traction rope and ensure the stability of the movement track of the traction rope.

[0054] Further, a reciprocating screw 600 is arranged on the frame body 410 in a rotating manner, the rotating axis of the reciprocating screw 600 is parallel to the axis direction of the reel 420, and one end of the limiting ring 500 is in transmission connection with the reciprocating screw 600.

[0055] In this embodiment, the reciprocating screw 600 is rotatably mounted on the frame body 410 through bearings or the like, and the rotating axis thereof is parallel to the axis direction of the reel 420. One end of the limiting ring 500 is connected with the reciprocating screw 600 through a screw nut or the like transmission component. When the reciprocating screw 600 rotates, it will drive the limiting ring 500 to reciprocate along a direction parallel to the axis of the reel 420 due to the special thread structure thereof.

[0056] In an example that can be implemented, the reciprocating screw 600 has helical grooves 421 with opposite helical directions, and one end of the limiting ring 500 slides in the helical grooves 421, and the reciprocating movement of the limiting ring 500 can be achieved by rotating the reciprocating screw.

[0057] In work, according to the winding and unwinding of the traction rope and the moving position of the cleaning piece 300, the position of the limiting ring 500 is accurately adjusted by controlling the rotation of the reciprocating screw 600, so that it better plays a role in limiting the swing of the traction rope.

[0058] Further, the second rotation driving device 700 is arranged on the frame body 410, and the second rotation driving device 700 is used to drive the reciprocating screw 600 to rotate.

[0059] In this embodiment, the second rotation driving device 700 is arranged on the frame body 410 by a stable mounting method, and a servo motor is selected here. The output shaft of the servo motor is connected with the reciprocating screw 600 by means of a shaft coupling or a suitable gear transmission assembly. When the system is running, the servo motor receives accurate instructions from the control system and drives the reciprocating screw 600 to rotate according to the preset rotation speed, rotation direction and rotation angle. Due to the high-precision control characteristics of the servo motor, the rotation of the reciprocating screw 600 is accurate and stable, so as to drive the limiting ring 500 to quickly and accurately move to the required position, thereby effectively limiting the swing of the traction rope.

[0060] Further, the electric control control module 800 is electrically connected with the first rotation driving device 430 and the second rotation driving device 700, and is used to control the rotation speed and direction of the first rotation driving device 430 and the second rotation driving device 700.

[0061] In this embodiment, the electric control control module 800 is installed at a suitable position and is electrically connected with the first rotation driving device 430 and the second rotation driving device 700 by wires. The electric control control module 800 internally contains microprocessors, driving circuits and other components. The microprocessor receives control instructions from the outside and information feedback from the sensor, and after processing, sends accurate control signals to the two servo motors through the driving circuit to control their rotation speed and direction.

[0062] In actual work, according to the working state of the rotary kiln 200, the position of the cleaning piece 300 and the preset cleaning program, the electric control control module 800 can adjust the operating parameters of the two servo motors in real time and accurately, and realize accurate control of the movement of the cleaning piece 300.

[0063] Further, the brush 900 is arranged at the limiting ring 500, and the brush 900 is used to clean the traction rope passing through the limiting ring 500.

[0064] In the embodiment, the brush 900 is arranged at a specific position of the limiting ring 500 by welding, bolt connection or other reliable fixing modes. The brush 900 can be made of a material with dense bristles, wear resistance and certain elasticity, such as a steel wire brush or a nylon brush. When the traction rope passes through the limiting ring 500, the brush 900 can be in full contact with the traction rope. During the movement of the traction rope, the brush 900 can clean the surface of the traction rope and remove the attached dust, sundries or small particles.

[0065] Further, the trigger 110 is arranged on the cleaning member 300, and two travel switches 120 are arranged at two ends of the cross beam 100, respectively. The trigger 110 is used to trigger the travel switches 120, and the travel switches 120 are electrically connected with the electric control module 800.

[0066] In the embodiment, the trigger 110 is firmly arranged on the cleaning member 300 by welding, screwing or other modes. The travel switches 120 are respectively installed at the two ends of the cross beam 100, and the positions are accurate and reliable. When the cleaning member 300 moves to the end of the cross beam 100 along the cross beam 100, the trigger 110 will contact and trigger the corresponding travel switch 120. After the travel switch 120 is triggered, an electric signal will be sent to the electric control module 800.

[0067] The cooperation of the trigger 110 and the travel switch 120 can accurately detect the position of the cleaning member 300, and provide accurate position information for the electric control module 800. This is helpful to realize the automatic control of the movement of the cleaning member 300, avoid the cleaning member 300 exceeding the effective stroke range of the cross beam 100, and ensure the safe and stable operation of the system.
