DETAILED DESCRIPTION

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] like Figure 1 As shown, this embodiment provides a desulfurization tower construction weld scar cleaning device, including a bracket 1, a lifting mechanism and a cleaning mechanism.

[0036] like Figure 2 As shown, the bracket 1 is in an inverted U shape, including two side plates and a top plate. The two side plates are symmetrically fixed at both ends of the top plate. The distance between the two side plates is greater than the outer diameter of the desulfurization tower. The second electric push rod 14 is fixed on the two side plates. One end of the second electric push rod 14 passes through the side plate and is connected to a pressure block 13. The pressure block 13 is located between the two side plates.

[0037] It can be understood that by placing the top plate on the top of the desulfurization tower so that the top of the desulfurization tower is located between the two side plates, the second electric push rod 14 drives the pressing block 13 to press the pressing block 13 against the outer wall of the desulfurization tower, thereby fixing the bracket 1.

[0038] like Figure 2 As shown, the lifting mechanism includes a reel 10, a traction rope 11, and a lifting motor 12. A lifting hole is provided on the top plate of the bracket 1. The reel 10 is arranged in the lifting hole and is rotatably connected to the inner wall of the lifting hole. The lifting motor 12 is arranged on the top plate and connected to the reel 10, and is used to drive the reel 10 to rotate. One end of the traction rope 11 is fixedly connected to the reel 10, and the other end of the traction rope 11 is connected to the cleaning mechanism. In this embodiment, the lifting motor 12 is a reduction motor, and the lifting motor 12 controls the rotation of the reel 10 to realize the retraction and release of the traction rope 11, thereby controlling the lifting and lowering of the cleaning mechanism.

[0039] like Figure 3 , 4As shown, the cleaning mechanism includes a lifting seat 2, a steering motor 3, a rotating seat 4, an electric telescopic rod 5, an electric brush, a first electric push rod 8, and a friction member 9. The lifting seat 2 is disc-shaped, and the center of the top surface of the lifting seat 2 is fixedly connected to the traction rope 11. Two first electric push rods 8 are arranged, and the two first electric push rods 8 are symmetrically arranged on the outer peripheral surface of the lifting seat 2. The friction member 9 is fixedly arranged on the side of the first electric push rod 8 away from the lifting seat 2. In this embodiment, the friction member 9 is a rubber block, and the friction member 9 and the first electric push rod 8 are detachably connected by clamping or screws. The side of the friction member 9 away from the first electric push rod 8 is an arc surface, and the diameter of the arc surface is equal to the inner diameter of the desulfurization tower, so that one side of the friction member 9 can completely fit the inner wall of the desulfurization tower, which is beneficial to improve the friction between the friction member 9 and the desulfurization tower and ensure the stability of the lifting seat 2 during the cleaning process; the friction member 9 can also be a friction gasket or other structure.

[0040] In addition, a monitoring component is arranged on the hoisting seat 2, and the monitoring component can obtain the image inside the desulfurization tower in real time, monitor the cleaning situation in real time, and ensure the cleaning effect.

[0041] like Figure 3 As shown, a mounting hole is axially provided at the bottom of the lifting seat 2, a rotating motor is arranged in the mounting hole, a rotating seat 4 is coaxially arranged below the lifting seat 2, and the rotating seat 4 is connected to the output shaft of the rotating motor so that the rotating seat 4 can rotate relative to the lifting seat 2. In this embodiment, two electric telescopic rods 5 are provided, and the two electric telescopic rods 5 are symmetrically arranged on the outer peripheral surface of the rotating seat 4. An electric brush is fixedly provided at one end of the electric telescopic rod 5 away from the rotating seat 4. The electric brush includes a servo motor 6 and a cleaning brush 7. The servo motor 6 is used to control the rotation of the cleaning brush 7 to clean the construction weld scar.

[0042] The applicable method of the desulfurization tower construction weld scar cleaning device is as follows: the bracket 1 is placed on the top of the desulfurization tower so that the top of the desulfurization tower is located between the two side plates of the bracket 1, and the second electric push rod 14 drives the pressing block 13 to press the pressing block 13 on the outer wall of the desulfurization tower, thereby fixing the bracket 1. The lifting motor 12 controls the rotation of the reel 10 to lift the cleaning mechanism to the place where cleaning is required; the first electric push rod 8 controls the friction member 9 to move toward the inner wall of the desulfurization tower so that the friction member 9 is pressed on the inner wall of the desulfurization tower, thereby fixing the lifting seat 2; after the lifting seat 2 is fixed, the electric telescopic rod 5 controls the cleaning brush 7 to move toward the inner wall of the desulfurization tower. After the cleaning brush 7 contacts the construction weld scar on the inner wall of the desulfurization tower, the servo motor 6 can be turned on to control the cleaning brush 7 to rotate to clean the weld scar, and at the same time, the steering motor 3 is started to make the rotating seat 4 rotate slowly, so that the cleaning brush 7 can thoroughly clean the entire circle of construction weld scars.
