The utility model is achieved in that a kind of rotary fast traffic dolly, it comprises positioning framework and is installed on the supporting rollern device of positioning framework bottom, wherein, it also comprises rotating frame, it is rotaryed connection with positioning framework by antifriction-bearing box and is positioned on the positioning framework, wherein: described antifriction-bearing box comprises that a bearing location inner ring, that is fixed under the rotating frame is fixed on the positioning framework and bearing outer ring, location outside the inner ring of bearing location and the rolling body between bearing location inner ring and outer ring, bearing location.
Above-mentioned a kind of rotary fast traffic dolly, wherein, also comprise one or two locating dowel pins, all relative knock hole that is provided with vertical direction on the plane of described positioning framework and rotating frame, described locating dowel pin can insert in the relative positioning hole to prevent that rotating frame from rotating.
Above-mentioned a kind of rotary fast traffic dolly, wherein, described locating dowel pin is two, is individually fixed in the knock hole that two abutting ends of rotating frame and positioning framework offer.
Above-mentioned a kind of rotary fast traffic dolly, wherein, described bearing location inner ring and all rectangular ring of bearing location outer ring relative cross-section, the horizontal part of this bearing location inner ring and outer ring, bearing location all is individually fixed on rotating frame and the positioning framework by some tie bolts, is provided with rolling body so that they make relative rotary motion between its vertical component effect.
Above-mentioned a kind of rotary fast traffic dolly, wherein, described rolling body is a spin.
Above-mentioned a kind of rotary fast traffic dolly, wherein, described supporting rollern device is four, comprises that separately one, one is placed in wheel on the axle, is positioned at the wheel endoporus and with an axle bonded assembly bearing, be fixed in the roller bearing end cap on the wheel and be fixed in the baffle plate at a two ends by nut by socket bolt.
Above-mentioned a kind of rotary fast traffic dolly wherein, also accompanies packing ring between described nut and the baffle plate, also be provided with spacer on the axle between described roller bearing end cap and the plate washer.
This device of the utility model can pass in and out the water sealed tank of 8 meters of length in the stove, rotate freely outside the stove or in stove, and no matter isolated plant is that rotation, straight line move, still along with rotation and straight-line motion carry out when mobile simultaneously, there is not any shaking phenomenon, and can correctly transport to the installation site, guarantee the safety of whole construction course, saved great amount of manpower and material resources simultaneously, improved the efficient of having constructed.In the process of embodiment, the work capacity of crane man is by the work capacity more than original need 6～8 people, time has 1 original many hours energy that water sealed tank is moved laterally to the installation site after the stove inward turning turn 90 degrees, reducing to only needs 2～3 people just water sealed tank can be moved on to the installation site in 1 minute, improve 60 times, alleviated the work capacity of crane man in this project greatly, saved human and material resources, improved the efficient of work, made whole engineering item finish construction task in advance in 72 hours.
