Abstract
The invention discloses a foldable inner support device. The invention provides a foldable inner support device having delicate structure, high structure stability and simple use mode and capable of being freely adjusted according to the specifications of steel cylinders. The foldable inner support device comprises a driving cylinder, a driving rod, a rod base 1, a rod base 2 and multiple foldable rod sets, wherein the driving rod is inserted in the driving cylinder, and is driven by the driving cylinder to linearly reciprocate; the rod base 1 is fixedly connected to one end, far from the driving cylinder, of the driving rod; the rod base 2 is in cup joint with the driving rod; the rod base 1 and the rod base 2 are both perpendicular to the driving rod; the foldable rod sets comprise support rods and auxiliary rods arranged along the shaft section of the driving rod; and the foldable inner support device comprises four foldable rod sets. The foldable inner support device is simple in placing and taking modes, can effectively finish the support of the inner walls of the steel cylinders in use, can freely adjust the size according to the specifications of the steel cylinders, and is excellent in use effect.
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 processing 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 " strut 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 friction 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 collapsible inner supporting device that freely adjusts.
Technical scheme of the present invention is: comprise driving cylinder, drive spindle, pole socket one, pole socket two and some folding rod groups, and described drive spindle to be located in described driving cylinder and to do straight reciprocating motion under the driving of driving cylinder; Described pole socket one is fixedly connected on described drive spindle one end away from described driving cylinder, and described pole socket two is socketed described drive spindle, and described pole socket one, pole socket two are all vertical with described drive spindle;
Described folding rod group comprises the strut bar and auxiliary rod that the shaft section along described drive spindle arranges, and one end of described strut bar is hinged on pole socket one, and one end of described auxiliary rod is hinged on pole socket two and the other end of auxiliary rod is hinged in the middle part of described strut bar.
Described collapsible inner supporting device comprises four folding rod groups, and described strut bar is hinged with rotary seat away from one end of described pole socket one, and axle center and the described folding rod group of described rotary seat are in the same plane.
Be provided with cushion block between described driving cylinder and described pole socket two, described cushion block is socketed on described drive spindle.
When the present invention uses, first this case entirety can be placed in steel cylinder, drive spindle is driven to shrink in driving cylinder by driving cylinder again, thus pole socket one is diminished gradually with the spacing of pole socket two, and then strut bar " is outwards opened " under the effect of auxiliary rod, and finally prop up the inwall of steel cylinder, thus complete support to steel cylinder inwall, reinforcement by some strut bars away from the circumference that the termination of pole socket one is formed; After being used to complete, then driving drive spindle protruding by driving cylinder, thus the termination of strut bar is separated with the inwall of steel cylinder, and then can remove easily.
In sum, this case has placement, taking-up mode is simple, the support to steel cylinder inwall effectively can be completed during use, the size adjustable of the circumference simultaneously formed away from the termination of pole socket one due to some strut bars, can carry out size adjusting freely according to steel cylinder specification when therefore making this case use, result of use is splendid.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, 1 is driving cylinder, and 2 is drive spindles, and 3 is pole sockets one, and 4 is pole sockets two, and 5 is folding rod groups, and 51 is strut bars, and 52 is auxiliary rods, and 6 is cushion blocks.
Detailed description of the invention
The present invention as shown in Figure 1, comprises driving cylinder 1, drive spindle 2, pole socket 1, pole socket 24 and some folding rod groups 5, and described drive spindle 2 to be located in described driving cylinder 1 and to do straight reciprocating motion under the driving of driving cylinder 1; Described pole socket 1 is fixedly connected on described drive spindle 2 one end away from described driving cylinder 1, and described pole socket 24 is socketed described drive spindle 2, and described pole socket 1, pole socket 24 are all vertical with described drive spindle 2;
Described folding rod group 5 comprises the strut bar 51 and auxiliary rod 52 that the shaft section along described drive spindle 2 arranges, one end of described strut bar 51 is hinged on pole socket 1, and one end of described auxiliary rod 52 is hinged on pole socket 24 and the other end of auxiliary rod 52 is hinged in the middle part of described strut bar 51.
Optimal enforcement mode of the present invention is: described collapsible inner supporting device comprises four folding rod groups 5, and described strut bar 51 is hinged with rotary seat away from one end of described pole socket 1, and axle center and the described folding rod group 5 of described rotary seat are in the same plane.
During use, can after the termination of strut bar props up the inwall of steel cylinder, the plane vertical with drive spindle exerts a force to driving cylinder, now, if the axle center of the axle center of drive spindle and steel cylinder is inconsistent, then will there is the phenomenon of " swingable " in one direction in driving cylinder, then the position of axis deviation is determined in the direction that can swing according to driving cylinder, and then adjust, until driving cylinder cannot swing.Like this, effectively can guarantee that the axle center of drive spindle and the axle center of steel cylinder are consistent by said method, and then provide actv. inner support to steel cylinder.
Be provided with cushion block 6 between described driving cylinder 1 and described pole socket 24, described cushion block 6 is socketed on described drive spindle 2.
