Detailed description of the invention
As shown in Figure 3, paper machine blanket on back roller erecting device provided by the invention comprises pole 20, and pole 20 has a host side 24.Accepting hole 240 is established in host side 24.The diameter of accepting hole 240 is suitable with the diameter of the later end 17 of roller 10.Please also refer to Fig. 4, host side 24 is for being set in the end 17 of later roller 10, and when using this erecting device to install woollen blanket, later namely the end 17 of roller 10 is housed in this accepting hole 240.
In certain embodiments, this pole 20 can be a tubing, such as steel pipe etc.The length of pole 20 can be suitable with the length of later roller 10.
This erecting device also comprises the fixed arm 22 be arranged on pole 20.The end of fixed arm 22 is provided with fixing hole 29.The end of fixed arm 22 is roughly concordant with the end of host side 24.After on the end 17 that host side 24 is set in later roller 10, the end of fixed arm 22 can abut and be fixed on later on roller 10, such as, be connected on the projection 15 of later roller 10, and utilizes the securing members such as screw to be located in fixing hole 29 to be fixed.
Embodiment shown in a figure only fixed arm 22 is extended by bending on pole 20, in other examples, also can be two or more.Fixed arm 22 can coordinate host side 24 to make pole 20 be fixed on more securely on the end 17 of later roller 10 together, makes the installation process of woollen blanket more smooth.The structure of fixed arm 22 does not limit the shape shown in figure, can be curved, can be linear etc. yet.
Further, host side 24 also can arrange screw 25, screw 25 extends through the sidewall of host side 24 and arrives in accepting hole 240, for abutting the end 17 of later roller 10, ensureing pole 20 and turning one's head being fixedly connected with of roller 10.
Further, this erecting device also comprises the fixing ear 23 be arranged on pole 20.Fixing ear 23 is arranged on the both sides of pole 20 symmetrically.Fixing ear 23 can be used for coordinating with suspender belt when installing woollen blanket, rotates when preventing pole 20 to be lifted.The position that the position of fixing ear 23 on pole 20 is enclosed within pole 20 according to suspender belt determines, usually can select 1/3 to 2/3 place in whole pole 20 length, be preferably 1/2 place.Because it is too far away, then higher to the requirement of strength of pole 20 from the end 17 of later roller 10 that suspender belt is enclosed within position on pole 20, it is too near from the end 17 of later roller 10 that suspender belt is enclosed within position on pole 20, then cannot reach the object facilitating installation woollen blanket.
When adopting above-mentioned erecting device that woollen blanket is installed, first woollen blanket part is filled in the upside 11 that paper machine also arrives later roller 10.The woollen blanket now having part exposes outside the end 17 of turning one's head roller 10.
Then unload the screw 16 on the end 17 of later roller 10, this end 17 of later roller 10 is unclamped from pedestal 18.The host side 24 of pole 20 is set on the end 17 of turning one's head roller 10.And with securing members such as screws, the projection 15 of the fixed arm 22 of pole 20 with later roller 10 is fixed together.When fixed arm 22 is arranged on diverse location, fixed arm 22 also can be made to be fixed together with other structures of later roller 10.
It is pointed out that the end 17 first can carrying out unclamping later roller 10 in certain embodiments, and pole 20 is fixed on the step on the end 17 of later roller 10, then carry out woollen blanket and fill in paper machine and the step arriving the upside 11 of later roller 10.Certainly also can understand the end 17 of unclamping later roller 10 to be also not particularly limited with the sequencing of the end 17 pole 20 being fixed on later roller 10.
Suspender belt is tied up on pole 20, then adjust the length of suspender belt, pole 20 is steadily lifted, meanwhile, later this end 17 of roller 10 is also steadily lifted, then the upside 11 woollen blanket being covered part later roller 10 curved around one after extract out from the downside 12 of later roller 10.Although another end 19 that it may be noted that later roller 10 is still stationary state, later the amplitude of lifting of this end 17 of roller 10 is less comparatively speaking, and later the free degree of another end 19 of roller 10 allows the operation such as to lift to this end 17 completely.In other words, later another fixing end 19 of roller 10 can not affect the aforesaid operations to end 17 in the process of installing woollen blanket.
Adjustment woollen blanket makes woollen blanket cover completely after later on roller 10, pole 20 is relay down, and unloads lower fulcrum bar 20 from later roller 10, finally retighten later roller 10 on pedestal 18.
Further, should understand while utilizing suspender belt to lift the end 17 of later roller 10, the action of woollen blanket covering, extraction and adjustment can be carried out.This process may be also simultaneously or repeatedly hocket, and such as, to the repeatedly adjustment of the later raising height of the end 17 of roller 10, covers the repeatedly adjustment etc. on later roller 10 to repeatedly attempting of extracting out of woollen blanket and to woollen blanket.
Because suspender belt to tie up on pole 20 but not on the end 17 of later roller 10, therefore the distance between suspender belt and end 17 is larger, when the length of adjustment suspender belt is toward pull-up, suspender belt can not hinder the woollen blanket exposed outside end 17, and therefore woollen blanket can not be stuck between suspender belt and end 17.Thus the process of follow-up adjustment woollen blanket can become smooth.In addition, due to can not woollen blanket be interfered toward pull-up suspender belt, therefore the amplitude of suspender belt pull-up can become large, and make the part of the close later downside 12 of roller 10 of projection 15 have certain space with pedestal 18, even if later roller 10 rotates due to unbalanced factor in the process of pull-up, still can keep a determining deviation between this projection 15 and pedestal 18, thus woollen blanket is being gone for a stroll and also become smooth because not hindering from the process that the downside 12 of later roller 10 is extracted out.
In order to make to keep desired spacing between suspender belt and the end 17 of later roller 10, simultaneously can not be too high to the strength demand of pole 20, the position of preferred suspender belt is placed on 1/3 to 2/3 place of the whole length of pole 20, and more preferably suspender belt is placed on 1/2 place of the length of pole 20.
In addition, in a preferred embodiment, this pole 20 arranges fixing ear 23.Fixing ear 23 is symmetrical arranged along pole 20.Suspender belt is enclosed within fixing ear 23, fixing due to fixing ear 23 pairs of suspender belts, and when can avoid suspender belt pull-up pole 20, pole 20 rotates, and also namely avoids later roller 10 because the rotation that causes of asymmetric structure.Thus, even if the amplitude that suspender belt is pulled upwardly pole 20 is less, the adjustment process of woollen blanket also can not be subject to the obstruction of projection 15 and pedestal 18.
The shape of this fixing ear 23 is not particularly limited, as long as can play effect of fixing suspender belt.In addition, in certain embodiments, hole can also be set on fixing ear 23, and suspender belt ties up in this hole.The setting position of this fixing ear 23 can be identical with the position of suspender belt on pole 20.
After adopting this erecting device, the horizontal range of the suspender belt distance later end 17 of roller 10 is elongated, therefore woollen blanket is inner without the need to being almost all tucked into paper machine harshly, but according to actual conditions, woollen blanket part can be put into paper machine inside, follow-up installation process woollen blanket can not be subject to the impact of suspender belt.In addition, tie up on the fixing ear 23 of pole 20 with suspender belt, then by regulating suspender belt length, very reposefully pole 20 can be inconjunction with later roller 10 and lift, there will not be the heavy side declivity phenomenon caused because of unsymmetrical factors when adopting conventional method, so can not damage or damage woollen blanket by pressure.There is no the interference of suspender belt, also there is no the inconvenience that the phenomenon of heavy side declivity causes, can comparatively freely regulate woollen blanket to put into length and the angle of paper machine inside, make woollen blanket turn one's head the installation Portable safety at roller 10 position.
