Abstract
The utility model discloses a tail sealing brush structure added with a spring plate for enhancing resilience force, which comprises an outer casing plate, a front protective plate and a back protective plate, wherein the front protective plate and the back protective plate are arranged on the outer casing plate. The tail sealing brush structure is characterized in that at least two layers of stainless steel wire groups are fixed in the outer casing plate through pins and disposed between the front protective plate and the back protective plate, the spring plate is arranged between the two layers of stainless steel wire groups, and the front protective plate, the back protective plate and the spring plate are all fixed in the outer casing plate through pins. Since the spring plate is added between the two layers of stainless steel wire groups, resilience force of the stainless steel wire groups is enhanced, service lives of the stainless steel wire groups are prolonged, failure in tail sealing during use is avoided, construction quality and progress are guaranteed while recovery or replacement frequency of the tail sealing brush and cost are reduced.
Description
Technical field
The utility model relates to a kind of shield tail sealing brush configuration of shield machine, what be specifically related to is a kind of shield tail sealing brush configuration that latch plate improves screen resilience that increases.
Background technology
Along with the development of China's urban construction, underground constructions such as underground rail traffic, cross-river tunnel increase day by day, and the shield structure advance distance in tunnel is also more and more longer.And shield machine shield tail sealing generally is made up of 3 road shield tails sealing brushes, forms two grease cabins, i.e. front deck and rear deck, and preceding twice are weak point shield ventral brush, the 3rd road is long shield ventral brush.In the shield driving process, the section of jurisdiction is actionless, and the shield body is to move continuously, so shield tail and the relative slip of existence between the tubulature sheet, enters in the shield structure in order to prevent outside sewage and silt etc., must be to carrying out encapsulation process between shield tail and section of jurisdiction.
The sealing of shield machine shield tail mainly is mounted on three road shield tail sealing brush sealings of shield tail inwall; but shield machine is after advancing continuously through long distance; the shield tail of its afterbody sealing brush can make the brush silk of shield tail sealing brush and preceding too greatly because of excessive abrasion or friction; rear wing loss of elasticity or weaken; the steel wire group of existing shield tail sealing brush and before; rear wing is by in the Shell Plate of dowel fixes; pin two ends and shell are fixed; before; rear wing is close to Shell Plate respectively; it in it steel wire group; and this fixed form; in its long-term use; before; the screen resilience of rear wing and steel wire group weakens, thereby causes the seal failure of shield tail.In work progress, repair or change shield tail sealing brush, cost is higher, and the life-span is short, and influences construction speed.
The utility model content
At the deficiency that exists on the prior art, the utility model purpose is that a kind of Stability Analysis of Structures is being provided, and improves the shield tail sealing brush configuration that the screen resilience and the increase latch plate in application life improve screen resilience.
To achieve these goals, the utility model is to realize by the following technical solutions:
A kind ofly increase the shield tail sealing brush configuration that latch plate improves screen resilience, it comprises Shell Plate and front fender and rear wing on the Shell Plate is set; It is characterized in that; by dowel fixes two-layer at least stainless steel wire group is arranged in the described Shell Plate; described stainless steel wire group is arranged between front fender and the rear wing; between described two stainless steel wire groups, also be provided with latch plate, described front fender, rear wing and latch plate all by described dowel fixes in Shell Plate.
Above-mentioned a kind of shield tail sealing brush configuration that increases latch plate raising screen resilience, wherein, above-mentioned pin is provided with 6 at least.
Above-mentioned a kind of shield tail sealing brush configuration that increases latch plate raising screen resilience wherein, also is provided with stainless steel cloth between above-mentioned two-layer stainless steel wire group.
Above-mentioned a kind of shield tail sealing brush configuration that increases latch plate raising screen resilience, wherein, the length of above-mentioned latch plate is less than the length of front fender and rear wing.
The beneficial effect that the utility model is compared with prior art had is:
The utility model increases latch plate between two-layer stainless steel wire group, increased the screen resilience of stainless steel wire group, prolonged its application life, avoid the inefficacy of shield tail sealing in use, construction quality and progress have been guaranteed, reduce the reparation of shield tail sealing brush or the number of times of replacing simultaneously, reduced cost.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
Embodiment:
Referring to Fig. 1, present embodiment provides a kind of shield tail sealing brush configuration that latch plate improves screen resilience that increases, and it comprises Shell Plate 10; In Shell Plate 10, be fixed with and have two-layer at least stainless steel wire group 15 between front fender 12, rear wing 14 and the forward and backward guard shield by pin 11; in the present embodiment; in Shell Plate 10, be fixed with two-layer stainless steel wire group 15; between two stainless steel wire groups 15, increase stainless steel cloth 16 and latch plate 13 are arranged; by stainless steel cloth 16 with two-layer stainless steel wire group 15 separately, the length of the second layer silk layer that stretches out Shell Plate 10 length and stainless steel wire group 15 of this stainless steel cloth 16 is approaching.
What deserves to be mentioned is; what latch plate 13 adopted is the spring steel plate of good springiness, is arranged between the two-layer stainless steel wire group 15, 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.
In the present embodiment, the pin 11 that is used for fixing front fender 12, rear wing 14, latch plate 13 and stainless steel wire group 15 is provided with 6, divides two rows to be arranged on the Shell Plate 10; Wherein, Shell Plate 10 fore-ends are promptly front-seat equidistantly to be provided with four, and back row is provided with two, has increased shield tail sealing brush silk group 15 is installed steadinesss.
During use, by between two-layer stainless steel wire group 15, increasing latch plate 13, guaranteed the screen resilience of stainless steel wire group 15, prolonged the application life of shield tail sealing brush, avoided the screen resilience forfeiture of stainless steel wire group 15 and outside sewage and silt etc. are entered in the shield structure, reduce unnecessary loss and use cost, thereby further guaranteed construction quality and progress.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof
