Description
Technical field
The present invention relates to the inner support field of steel cylinder.
Background technology
At present, heavy caliber steel cylinder is in the process of depositing, lift and transporting, because self gravitation, volume are very big, therefore very easily there is distortion in various degree, the circularity of steel cylinder is made to produce great deviation, seriously have impact on the subsequent job (as docking cannot be completed between two steel cylinders, steel cylinder cannot stretch into preset hole medium) of steel cylinder, greatly reduce production efficiency and bring high secondary operations rate.
To this, State Bureau on December 5th, 2012 announced a " a kind of inside support ring for large glass steel cylinder joint " by name, application number is the document of " 201220165358.6 ", this case proposes a kind of " ring body " that completed inner support by multiple " support bar ", thus by " ring body " to complete the support to steel cylinder inwall.
But people find after reality uses, and this case still exists following problem: the steel cylinder that, only can adapt to a certain specific standard size, and the specification as steel cylinder changes, then need again to make whole " inside support ring ", waste time and energy and cost is high; Two, the external diameter due to this type of " inside support ring " is consistent with the internal diameter of target steel cylinder, and therefore, after steel cylinder is shaping, the process " inside support ring " be placed in steel cylinder is very loaded down with trivial details and inconvenient; Three, after " inside support ring " puts into steel cylinder, due to great frictional force will be there is between the outer wall of " inside support ring " and the inwall of steel cylinder, therefore, the great inconvenience that the taking-up of " inside support ring " brings also is given.
Summary of the invention
The present invention is directed to above problem, provide that a kind of delicate structure, structural stability are high and occupation mode simple, during use, can carry out according to steel cylinder specification the inner supporting device that freely adjusts.

Detailed description of the invention
The present invention as Figure 1-5, comprises line shaft 1, bracing or strutting arrangement 2 and a pair centring means 3;
Described line shaft 1 offers external screw thread;
Described bracing or strutting arrangement 2 comprises pole socket 1, pole socket 2 22 and some support bar group 23, line shaft 1 described in described pole socket 1 empty set, and described pole socket 2 22 is socketed described line shaft 1 and the inwall of pole socket 2 22 offers the internal thread with described external screw thread adaptation; Like this, turn line shaft can to the adjustment of the spacing of pole socket one and pole socket two; Described support bar group 23 comprises the bar 1 and bar 2 232 that the shaft section along described line shaft 1 arranges, one end of described bar 1 is hinged on pole socket 1, and one end of described bar 2 232 is hinged on pole socket 2 22 and the other end of bar 2 232 is hinged on the middle part of described bar 1; Like this, during pitch smaller between pole socket one, two, bar one " outwards opens under the effect of bar two ";
Make the present invention when the steel cylinder of different specification size, by regulating the spacing of pole socket one and pole socket two, with the angle of adjusting rod one with line shaft, and then change the size (this size finally equals the internal diameter of target steel cylinder) of the circumference that some bars one are formed away from one end of line shaft, thus the present invention is had be convenient to place, take out and can carry out according to the specification of steel cylinder the advantage that freely adjusts.
But, people also find when reality uses, during use, after bar one " opening completely ", if the axle center of the axle center of line shaft and steel cylinder is inconsistent, the circumference formed the one end directly causing some bars one away from line shaft cannot be formed the inside of steel cylinder and effectively, reliably support, and serious even makes it be out of shape compressing steel cylinder;
To this, in this case, set up a pair centring means, specifically:
Centring means described in a pair 3 points is located at the two ends of described line shaft 1, and described centring means 3 comprises the contrary threaded rod 34 of installing rack 31, timing gear roller box 32, a pair helical gear 33 and a pair thread rotary orientation; Described installing rack 31 to be located at below described line shaft 1 and to comprise top board 311, base plate 312 and pair of side plates, the end face of described top board 311 is provided with the bearing block for accommodating described line shaft 1, and described base plate 312 is fixedly connected on below described top board 311 by pair of side plates; Threaded rod 34 described in a pair vertically arranges and is located in top board 311 and base plate 312 successively, helical gear 33 described in a pair between described top board 311 and base plate 312 and is respectively socketed threaded rod 34 described in a pair, is threaded connection between described helical gear 33 and described threaded rod 34; Described timing gear roller box 32 comprises casing 321, power shaft 322 and output shaft 323, described casing 321 is fixedly connected on the side of described installing rack 31 away from described bracing or strutting arrangement 2, described power shaft 322 is removably connected on described line shaft 1, and described output shaft 323 is connected with the bevel gear be engaged on described in a pair between helical gear 33; Like this, when line shaft turn, power will be passed between a pair helical gear along timing gear roller box, and drive a pair helical gear to rotate, and then drive the threaded rod be threaded connection for a pair in helical gear axle center synchronously to stretch out downwards.
Described pole socket 1 is fixedly connected with on the top board 311 in centring means 3 described in wherein.
Wherein, due to the existence of timing gear roller box, make some bars one when " opening " gradually, the bottom of four threaded rods be in all the time some bars one away from one end of line shaft formed with the axle center of line shaft for the center of circle circumferentially, and under the drive of line shaft gradually downwards " stretching out "; Like this, afterwards (namely prop up the inwall of steel cylinder) until some bars one " opening completely ", effectively can guarantee that the axle center of line shaft keeps highly consistent with the axle center of steel cylinder.
This case is when placing, only need turn line shaft, synchronously can realize " opening " of some bars one and " stretching out " of four threaded rods, and finally guarantee that the axle center of line shaft is consistent with the axle center of target steel cylinder, thus effectively realize the inner support to steel cylinder afterwards some bars one " opening completely "; And when taking out, also only needing reverse turn line shaft can take out a whole set of inner supporting device easily, operating very easy.In sum, this case has that delicate structure, structural stability are high and occupation mode simple, can carry out the feature that freely adjusts during use according to steel cylinder specification.
The end face of described helical gear 33 is provided with the upper cutting ferrule of fitting with the bottom surface of described top board 311 and the bottom surface of helical gear 33 is provided with the lower cutting ferrule of fitting with the end face of described base plate 312.Make in use, the spacing of helical gear and top board can remain unchanged, thus can calculate the Bottom Runby of threaded rod according to the corner of line shaft.
Described bearing block comprises pedestal and bearing, line shaft described in described pedestal empty set and be fixedly connected on the end face of described top board, and described bearing is connected between described pedestal and described line shaft.
As shown in Figure 4, described bar 1 is also provided with arc boss 233 away from one end of described pole socket 1.
