Abstract
The invention relates to a rotating scale scraping device for a pipeline robot. The rotating scale scraping device is characterized by comprising a rotary scraping cutter and a drive shaft which are fixedly connected. First-end saw teeth and second-end saw teeth are formed at two ends of the cutter body of the rotary scraping cutter. The first-end saw teeth have n teeth, and the second-end saw teeth have n-1 teeth, wherein n=3, 4, 5 or 6. The difference of the first-end saw teeth and the second-end saw teeth is 180 degrees. The positions of the tooth gaps of the first-end saw teeth are the positions of the teeth of the second-end saw teeth, namely first-end saw teeth and the second-end saw teeth are arranged in a staggered manner. The rotating scale scraping device has the advantages that layered rotating scraping of scales can be achieved; during rotation of the cutter, the part distant from the center has large rotation inertia and large resistance, scraping is performed according to stubborn degree of scales, and accordingly rotating scraping resistance is low and drive power is saved while scraping efficiency is unaffected; the rotating scale scraping device is reasonable in structure, convenient to use, high in operation efficiency and good in scale scraping effect.
Description
Technical field
The present invention relates to Robotics field, especially relate to rotation scraper device for a kind of pipe robot.
Background technology
Thermal power plant's ash conveying pipe can form hard and crisp dirt unavoidably because of throughout the year use.In order to reduce transporting resistance in ash-water pipeline, reduce dust removing system energy consumption, guarantee the safe operation of unit, must carry out effective scale removal and maintenance to pipeline.In the situation that artificial descaling method exists shortcomings, pipe robot, as a kind of effective eliminating sludge in pipe equipment, has obtained increasing application.
Current existing pipeline cleaning device mainly contains helical feed sewage disposal apparatus and crab rake sewage disposal apparatus.Helical feed sewage disposal apparatus is the steel drum with spiral, utilizes spiral rotating by dirt removal.This apparatus structure is simple, removes contamination effective.But owing to can not adjusting steel drum radius, be difficult to realize the work of removing contamination to any pipeline.Crab rake sewage disposal apparatus is harrowed pincers, transport tape, motor etc. by crab and is formed.This apparatus structure is simple, and insensitive to the character of dirt, tool is flexible within certain limits.But due to the restriction of self structure, to the hard scale of docile pipeline, remove not thorough.
It is end effector mechanism that current existing pipe robot mainly adopts high-pressure water jet, utilizes High-Pressure Water that dirt is washed open, and dirt is come off.This method can realize unit and not shut down scale removal, and scale removal cost is low.But the burden of bringing to motor owing to pulling water pipe increases, and harder dirt can not be removed thoroughly, and self has some limitations.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of rational in infrastructure, easy to use, operating efficiency is high, rotation scraper device for the pipe robot of removing contamination effective.
The technical solution used in the present invention is, rotation scraper device for a kind of pipe robot, it is characterized in that: it comprises revolving scraper, driving shaft, revolving scraper and driving shaft are connected, one end at the cutter hub of revolving scraper is provided with first end sawtooth, at the other end of the cutter hub of revolving scraper, is provided with the second end sawtooth.
First end sawtooth is n tooth, and the second end sawtooth is n-1 tooth, wherein: n=3,4,5 or 6.
First end sawtooth and the second end sawtooth differ 180 °, and the backlash position of first end sawtooth is the tooth position of the second end sawtooth, is and is crisscross arranged.
Rotation scraper device for a kind of pipe robot of the present invention, because the distance at the first end sawtooth of revolving scraper and every tooth pitch center of the second end sawtooth is all not identical, first end sawtooth and the second end sawtooth differ 180 °, the backlash position of first end sawtooth is the tooth position of the second end sawtooth, be and be crisscross arranged, can realize layering, dirt is rotated to scraping; Cutter is in the larger part of distance at rotation process Zhong，Ju center, and rotator inertia is larger, the resistance producing is also just larger, obstinate degree for dirt is carried out scraping, like this, is not affecting under the prerequisite of scraping rate, rotation scraping resistance is little, save driving power, it is rational in infrastructure, easy to use, operating efficiency is high, removes contamination effective.
Accompanying drawing explanation
Fig. 1 is that a kind of pipe robot of the present invention is looked schematic diagram with the structure master of rotation scraper device;
Fig. 2 is that schematic diagram is looked on a left side of Fig. 1;
Fig. 3 rotates scraper device to be connected job state schematic diagram with pipe robot in Fig. 1.
In figure: 1 revolving scraper, 2 first end sawtooth, 3 second end sawtooth, 4 nuts, 5 keys, 6 driving shafts, 7 robots, 8 intelligent controllers.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 1-Figure 3, rotation scraper device for a kind of pipe robot of the present invention, comprises revolving scraper 1, driving shaft 6, and revolving scraper 1 adopts arc design, and the cutter hub of revolving scraper 1 is that middle part is wide, two ends narrow structure.Revolving scraper 1 is connected with driving shaft 6 by key 5 and nut 4.In one end of the cutter hub of revolving scraper 1, be provided with the first end sawtooth 2 of three teeth, at the other end of the cutter hub of revolving scraper 1, be provided with the second end sawtooth 3 of two teeth.The distance at every tooth pitch center of first end sawtooth 2 and the second end sawtooth 3 is all not identical, first end sawtooth 2 and the second end sawtooth 3 differ 180 °, the backlash position of first end sawtooth 2 is the tooth position of the second end sawtooth 3, is and is crisscross arranged, and can realize layering, dirt is rotated to scraping.Cutter is in the larger part of distance at rotation process Zhong，Ju center, and rotator inertia is larger, the resistance producing is also just larger, obstinate degree for dirt is carried out scraping, like this, is not affecting under the prerequisite of scraping rate, rotation scraping resistance is little, save driving power, it is rational in infrastructure, easy to use, operating efficiency is high, removes contamination effective.The first end sawtooth 2 of revolving scraper 1 of the present invention and the number of teeth of the second end sawtooth 3 are set as required, also can adopt first end sawtooth 2 for n tooth, and the second end sawtooth 3 is n-1 tooth, wherein: n=3,4,5 or 6.
During operation: the be connected intelligent controller 8 of ，You robot 7 of the driving shaft 6 of rotation scraper device and the drive unit of robot 7 is controlled operation, before pipe robot work, can select matched revolving scraper 1 according to pipe diameter size.Robot 7 and intelligent controller 8 thereof are prior art products.
The above has only expressed several embodiment of the present invention, though description is concrete and detailed, can not therefore be construed as limiting the scope of the patent.To those skilled in the art, or else depart under the prerequisite of the present invention's design, can also make distortion and retouching, these all belong to protection scope of the present invention.
