Fig. 3 is one embodiment of the invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
Embodiment:
Referring to Fig. 1 and Fig. 3, present embodiment provides the novel shield tail sealing brush of a kind of Stability Analysis of Structures, slip-off preventing, and it comprises Shell Plate 10, front fender 12, steel spring plate 13, rear wing 14 and two-layer stainless steel wire group 15; Between two-layer stainless steel wire group 15, increase stainless steel cloth 16 and steel spring plate 13 are arranged, by stainless steel cloth 16 with two-layer stainless steel wire group 15 separately, the length of stretching out Shell Plate 10 length and stainless steel wire group 15 second layer silk layers of this stainless steel cloth 16 is approaching.What steel spring plate 13 adopted is the spring steel plate of good springiness, is arranged between the two stainless steel wire groups 15, and as the middle guard shield of shield tail sealing brush, its length is less than the length of front fender 12 and rear wing 14, is used to keep the good screen resilience of stainless steel wire group 15.
Two-layer stainless steel wire group 15 is fixed between front fender 12 and the rear wing 14; between itself and front fender 12 and the rear wing 14 wired hoop 17 is installed, is used for increasing the compaction process flat side down of stainless steel wire group 15 and stainless steel silk group 15 is compressed full.This front fender 12, steel spring plate 13, rear wing 14 and wired hoop 17 all are fixed in the Shell Plate 10 by pin 11, and this pin 11 is provided with six, divide two rows to be arranged on the Shell Plate 10; Wherein a row is that the front row is provided with four, and another row i.e. back row is provided with 2; And wired hoop 17 is fixed by front-seat four pins 11.
In the present embodiment, process the suitable bellmouth of the head of a nail of pin 11 on the Shell Plate 10, the head of a nail of this pin 11 has been filled Shell Plate internal tapered hole capacity, between the other end of each pin 11 and bellmouth, weld by argon arc welding, itself and Shell Plate are fixed as one, kept the lateral surface of Shell Plate smooth, smooth, the operation of having avoided Shell Plate to polish, polish.
Two-layer stainless steel wire group 15 tail ends all were fixed on silk card 19 respectively by fixed strip 18 in, this card was U type structure, is arranged on the periphery of fixed strip 18, and fixed strip 18 is stuck in wherein.Be equipped with at fixed strip 18 two ends be the U type block card 20(referring to Fig. 2), this block card 20 is installed in Si Kanei, is used to stop that the outer of fixed strip 18 wear and avoid fixed strip 18 and stainless steel wire to come off in silk card 19.
It should be noted that the periphery of the stainless steel wire of composition stainless steel wire group 15, promptly be arranged between fixed strip 18 and the silk card 19 around fixed strip 18.What the fixed strip 18 of present embodiment adopted is reinforcing bar, when silk card 19 is installed, at first be that stainless steel wire and reinforcing bar are placed on an openend of card 19, reinforcing bar is placed on the stainless steel wire, presses down reinforcing bar, makes the stainless steel wire bending, reinforcing bar is inserted in the silk card 19, block 19 two ends at silk then and put into block card 20, compress silk card 19, finish the fixing of stainless steel wire group 15 tail ends.
When Shell Plate 10 compresses, wired hoop 17 is compressed, in the middle of stainless steel wire group 15 is pressed on, improve stainless steel wire group 15 flat side down degree by wired hoop 17, and, when stainless steel wire is further clamped, make two wired hoop 15 pitch smaller, more tight between the steel wire of stainless steel wire group 15, improve the plumpness that stainless steel wire group 15 compresses, then, fix, guaranteed the smooth, smooth of Shell Plate 10 surfaces by pin 11 bellmouths adaptive with it.
In the use,, avoided coming off of stainless steel wire, increased stainless steel wire group 15 stability is installed owing to increased wired hoop 17 and block card 20.Simultaneously, increase steel spring plate, guaranteed the screen resilience of stainless steel wire group, guaranteed the sealing performance of shield machine shield tail, significantly reduced the number of times of repairing or change shield tail sealing brush, reduced construction cost, accelerated construction speed.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof
