Such as, piling bar is the main load-carrying member of harbour, its seriously corroded affects the safety and the service life of harbour, therefore must apply effective protection to it.At piling bar surface-coated anticorrosive paint is a kind of effective salvo, yet, because corrosive environment is abominable, the anti-corrosion measure of sea port dock steel construction will be lost efficacy after 8～10 years in operation usually, particularly wave spatter the district and the piling bar surface corrosion situation in tidal range district the most serious, corrosion ion such as chlorion makes the average corrosion rate of harbour piling bar reach 0.3～0.4mm/ in the seawater, local corrosion speed even reach 1mm/; Perch simultaneously also can be accelerated the corrosion rate of piling bar at the marine growth in tidal range district.Therefore, need regularly anticorrosion maintenance to be carried out on the piling bar surface, anticorrosion with painting coating needs special equipment to finish this corrosion prevention operation again.
" machine science and technology " publication the 27th the 8th phase of volume of August in 2008 has been delivered the article of " harbour piling bar tidal range district and wave spatter district's automation anticorrosion treatment technology and equipment research " by name, article numbering 1003-8728 (2008) 08-1077-04.This article discloses and a kind ofly can carry out the antiseptic implement of automation to the harbour piling bar, and this implement has a circular scanning mechanism that is used for the installation exercise instrument, can carry out scan process to the circumferential surface of piling bar.But the structure of this circular scanning mechanism is too simple and crude, and poor rigidity, kinetic stability are bad, are difficult to satisfy implement to robust motion and demands for bearing capacity.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of stationarity and the better circular scanning of bearing capacity mechanism, to overcome the above-mentioned defective of prior art.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of circular scanning mechanism, the support platform and the camber line guide rail that comprise a circular arc, the camber line guide rail can slide along the support platform camber line, described support platform comprise a rectangular tube and be connected rectangular tube below in, Side fascia, in, respectively be fixed with a plurality of bracing or strutting arrangements on the Side fascia, be equipped with a guide wheel in each bracing or strutting arrangement, the wheel rim of guide wheel is provided with the groove of annular, in the part wheel rim of guide wheel inserts, between the Side fascia, described camber line guide rail is positioned at, between the Side fascia, the both sides of camber line guide rail are provided with convex tendon, and described convex tendon matches with groove on the guide wheel.
Preferably, the cross section of described convex tendon is trapezoidal.
Preferably, support platform and camber line guide rail are semicircle.
Preferably, the cross section of described camber line guide rail is a square tube type.
Preferably, the outer rim of described camber line guide rail is provided with gear ring, also is provided with a gear on the support platform and is meshed with described gear ring, and gear is connected with motor.
Preferably, described motor is a hydraulic motor.
Compared with prior art, the present invention has that structural rigidity is good, bearing capacity is strong, deadweight is little, the characteristics of motion smoothing, good stability.

Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is the overall structure schematic diagram of circular scanning of the present invention mechanism.
Fig. 2 is the support and the drive connection schematic diagram of camber line guide rail.
Fig. 3 is the structural representation of a cross section of the present invention.
Among the figure: 1, support platform 2, camber line guide rail 3, bracing or strutting arrangement 4, motor 5, gear 6, gear ring 11, rectangular tube 12, lining 13, Side fascia 21, convex tendon 31, groove 32, guide wheel 33, wheel shaft
The specific embodiment
As shown in Figure 1, a kind of circular scanning of the present invention mechanism comprises a support platform 1 and a camber line guide rail 2, support platform 1 and camber line guide rail 2 be semicircular in shape roughly, camber line guide rail 2 can slide along support platform 1 camber line, support platform 1 upper edge circular arc is installed with a plurality of bracing or strutting arrangements 3 and is used to support camber line guide rail 2, and the middle part of support platform 1 also is installed with motor 4 and is used to drive camber line guide rail 2.
As shown in Figure 2, be fixed with gear ring 6 on the excircle of camber line guide rail 2, motor 4 is connected with a gear 5, and gear 5 is meshed with gear ring 6, thereby motor 4 can drive 2 motions of camber line guide rail.Because when carrying out the piling bar corrosion prevention operation, need anticorrosion with painting coating, for requirement of explosion proof, motor 4 preferably adopts hydraulic motor.
As shown in Figure 3, support platform 1 comprises a rectangular tube 11 and the inside and outside wallboard 12,13 that is connected the rectangular tube below, and inside and outside wallboard 12,13 is the concentric circles arc, and bracing or strutting arrangement 3 is divided into two rows and is fixedly mounted on respectively on the inside and outside wallboard 12,13.This structure of support platform 1 has good rigidity and intensity, has good bearing capacity.Be equipped with a guide wheel 32 in each bracing or strutting arrangement 3, guide wheel 32 is installed on the wheel shaft 33, and the wheel rim of guide wheel 32 is provided with the groove 31 of annular, and the part wheel rim of guide wheel 32 passes inside and outside wallboard 12,13, inserts between lining 12 and the Side fascia 13.Also between inside and outside wallboard 12,13, the cross section of camber line guide rail 2 is a square tube type to camber line guide rail 2, and its both sides are provided with convex tendon 21, and convex tendon 21 matches with groove 31 on the guide wheel.The cross section of convex tendon 21 and groove 31 is trapezoidal, and guide wheel 32 just can be played a supporting role simultaneously like this, can support camber line guide rail 2, and camber line guide rail 2 can not fallen down.Simultaneously, groove 31 is to the motion guide of camber line guide rail 2 time, and guide wheel 32 rotates simultaneously, makes motion more steadily along sliding.Camber line guide rail 2 can both obtain the support of a plurality of guide wheels 32 in the optional position of sliding, thereby guarantees the stationarity and the bearing capacity of its motion.
The two ends of camber line guide rail 2 can the installation exercise instrument, when camber line guide rail 2 when support platform 1 is moved, power tool can carry out cleaning and spraying anticorrosive paint to the whole circumference of piling bar, adds the vertical up-or-down movement of support platform 1, just can carry out operation to the cylinder of piling bar.
