Abstract
The invention relates to a flexible joint protecting device based on a muddy water pipeline in a muddy water shield. The flexible joint protecting device is applied to the field of fluid transportation and comprises a flexible joint between two segments of pipelines, and a neck bush is arranged in the flexible joint. An outer protecting cover is arranged outside the flexible joint. The flexible joint protecting device based on the muddy water pipeline in the muddy water shield is convenient to manufacture and low in manufacturing cost, and effectively prevents the flexible joint from being abraded and flushed by fluids, protects components around the flexible joint and has great popularization value.
Description
Technical field
The present invention relates to a kind of slurry-water balance type shield tunnel construction equipment, be specifically related to a kind of flexible joint protective gear based on muddy water pipeline in the slurry shield, be applied to the fluid transportation art.
Background technique
In the large-scale slurry shield work progress, the muddy water system is one of main system of slurry shield, in the muddy water system mainly is to be made of pipeline and fluid pump, if problem has appearred in the muddy water pipeline, will cause whole shield machine to stop driving.The muddy water pipeline is made of flexible joint, steel pipe, flexible pipe, flange and gate valve etc.The flexible joint effect is to prevent that the vibrations of pump from causing that whole muddy water system produces resonance effect, because flexible joint often is installed on the import and export position of fluid pump, wearing and tearing very easily appear, and flexible joint contraction, stretching and seismism can occur in the course of the work, therefore can accelerate the wearing and tearing of flexible joint.In the slurry shield work progress, the explosion of flexible joint is a ubiquitous phenomenon, the explosion of flexible joint will cause the muddy water of high pressure to splash all around, a large amount of mud pollutes the environment and damages neighbouring component and electric elements, cause shield machine segment assembly unit position ponding, and the difficult discharging of ponding, even can cause shield machine to stop driving for a long time, cause the soil body landslide of shield machine front, influence whole engineering.
Summary of the invention
Purpose of the present invention is exactly wear problems often to occur at flexible joint in the slurry shield construction, and a kind of flexible joint protective gear based on muddy water pipeline in the slurry shield is provided.Prevent fluid to the wearing and tearing of flexible joint and wash away and prevent protection to parts around the flexible joint.
The technical solution used in the present invention is: a kind of flexible joint protective gear, and it comprises the flexible joint that is arranged between two segment pipes, and described flexible joint inside is provided with neck bush, and described flexible joint outside is provided with outer protective cover.
Adopt the beneficial effect of such scheme to be: can make fluid along the inboard process of neck bush, only neck bush be worn and torn, reduce fluid to wearing and tearing and the scouring effect of flexible joint, flexible joint is used for preventing because the equipment vibrations cause the resonance of whole pipeline; It is damaged that outer protective cover can prevent effectively that flexible joint from occurring, and the high-pressure liquid ejection damages surrounding devices, component and personnel.
Further preferred construction, described neck bush one end is provided with the flanging of fixedlying connected for the flange plate on the pipeline, the neck bush the other end and flexible joint end inwall overlap joint.
Further preferred construction, described neck bush inwall is provided with the built-up welding protective layer in face of the surface of fluid.Fill out the working life that suitable wear-resistant material layer can improve neck bush at neck bush inwall heap, reduce and change number of times.
Further preferred construction, described outer protective cover is formed by connecting by two half round posts.Conveniently take inspection and replacing to flexible joint apart.
Further preferred construction, described outer protective cover end is by being bolted on the pipeline outer wall.
Further preferred construction is provided with sealing gasket between described outer protective cover and the pipeline outer wall.
Further preferred construction, described sealing gasket is rubber.
Further preferred construction, described flexible joint sidewall is for extending out circular arc.
Further preferred construction, described flexible joint two ends are respectively equipped with the flanging of fixedlying connected for the flange plate on two segment pipes.
That the present invention makes is more convenient, manufacturing expense is cheap, prevents fluid effectively to the wearing and tearing of flexible joint and washes away and prevent that the protection of parts around the flexible joint is had high promotional value.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments, be convenient to be well understood to the present invention, but they do not constitute restriction to the present invention.
As shown in Figure 1, the present invention includes the flexible joint 1 that is arranged between two segment pipes, flexible joint 1 sidewall is for extending out circular arc, and flexible joint 1 two ends are respectively equipped with the flanging 1.1 of fixedlying connected for the flange plate 2 on two segment pipes.Flexible joint 1 inside is provided with neck bush 3; neck bush 3 one ends are provided with the flanging 3.1 of fixedlying connected for the flange plate on the pipeline; neck bush 3 the other ends and flexible joint 1 end inwall overlap joint, neck bush 3 inwalls are provided with built-up welding protective layer 5 in face of the surface of fluid.Flexible joint 1 outside is provided with outer protective cover 4; outer protective cover 4 is formed by connecting by two half round posts; outer protective cover 4 ends are fixed on the pipeline outer wall by bolt 6; be provided with sealing gasket 7 between outer protective cover 4 and the pipeline outer wall; fixing and sealing gasket 7 prevents that it from going here and there up and down to outer protective cover 4 by bolt 6, and sealing gasket 7 is rubber.
Among the present invention since mud to the wearing and tearing of flexible joint 1 mainly based on erosive wear, so the hardness of neck bush 3 materials is not main, but guarantee under the prerequisite of certain degree of hardness, increase the plasticity and toughness of material and the coordination ability of microstructure, being conducive to increase the anti-impact erosion ability of neck bush, is steel or stupalith etc. so the type selecting of neck bush 3 materials adopts Mn.
During installation; neck bush 3 is embedded in the flexible joint 1; then flexible joint 1 and neck bush 3 are installed between the pipeline; because flexible joint 1 inconsistent phenomenon can occur in installation process; break away from after flexible joint 1 tension that causes for fear of dislocation; so when installing with bolt the flanging 1.1 of flexible joint 1 respectively with two segment pipes on flange plate 2 fixedly connected together; the flanging 3.1 of neck bush 3 one ends and the flange plate 2 on the pipeline are bolted to connection; outer protective cover 4 is installed in the outside at last, outer protective cover 4 ends are fixed on the pipeline outer wall by bolt 6.
The present invention realizes anti-wear purpose by the flexible joint 1 inner neck bush that arranges 3, bears and subdues most of mud to the wearing and tearing of flexible joint 1; By the high pressure mud that outer protective cover 4 shutoff flexible joints 1 explosion produces, prevent from jeopardizing component on every side after flexible joint 1 wearing and tearing, effectively prevented the harm that flexible joint 1 explosion brings.
The content that this specification is not described in detail belongs to related domain professional and technical personnel's known prior art.
