Abstract
The utility model relates to a special mechanical equipment field of municipal administration tunnel engineering construction. A pipe pushing jack articulates sealing device, establishes articulated anterior shield assembly and tail shield including the cover, and set up twice on the tail shield outer wall that corresponds with the anterior shield assembly and sealed the recess the sealed recess of twice in all be provided with articulated sealing washer, all to mate the laminating sealed with anterior shield assembly inner wall for the outer end of the articulated sealing washer of twice, the interior manual oiling system that is provided with that feeds through of seal chamber between the articulated sealing washer of twice. The utility model discloses with the sealed pressurize of traditional articulated sealing washer, the sealed precautionary measures with the polyurethane system of grease through addding manual oiling system have played the dual -protection measure, have guaranteed pipe pushing jack tunnel construction's security, reliability underground.
Description
Technical field
This utility model relates to municipal tunnel engineering construction special mechanical equipment field, is specifically related to a kind of push-bench hinged
Sealing device.
Background technology
At home, the composite duct such as waterpipe, blow-off line, gas piping, heat distribution pipeline, power cable, communication cable
Be typically all direct-burried underground and intricate, need again to excavate road surface when again laying or repair pipeline, not only cause through
Ji waste has an effect on traffic.Many pipelines cannot meet urban development needs, along with the development of the urbanization of China, city
City's pipeline network construction will rise to new height, and composite duct will the most constantly be popularized, and construction by pipeline jacking method is executed with it
The advantages such as work speed is fast, cavitation quality is high, safe and environment-friendly will be able to fast development.
In jacking construction, tunnel is mainly near level of ground water or below level of ground water, because of water penetration and the top on stratum
There is the factors such as the pressure of 3bar in pipe machine excavation face and periphery, push-bench needs a kind of deformation behavior in work progress
By force, the radial type sealing device of good seal performance.
Utility model content
The purpose of this utility model is the problem and shortage for above-mentioned existence, it is provided that a kind of reasonable in design, uses
Hinged sealing ring and the sealing of oils and fats and pressure-maintaining structure, and having polyurethane to carry out, the push-bench of duplicate protection is hinged seals dress
Put.
For reaching above-mentioned purpose, adopted the technical scheme that:
A kind of push-bench hinge seal device is including sheathed hinged anterior shield assembly and tail shield, corresponding with anterior shield assembly
Offering two seals groove on tail shield outer wall, be provided with hinged sealing ring in described two seals groove, twice are cut with scissors
Gluing, sealing is all mated with anterior shield assembly inwall in the outer end connecing sealing ring, connection in the annular seal space body between the hinged sealing ring of twice
It is provided with manual injection system.
Being additionally provided with polyurethane system between described anterior shield assembly afterbody and corresponding sheathed tail shield, described is poly-
Urethane system is positioned at the outside of hinged sealing ring.
Use technique scheme, acquired provide the benefit that:
The design of the hinged sealing ring of twice of the present utility model, compensate for producing with tail shield when anterior shield assembly travel direction adjusts
Raw different gap, determines that the parameter of hinged sealing ring elastic deformation amount is arranged, thus meets with more superior cost performance and seal
Effect；Additionally, by by the manual injection system being arranged between the hinged sealing ring of twice, it is ensured that hinged sealing ring is more
Add and work under excellent working condition；By arranging polyurethane system outside hinged sealing ring, play double protection measure, really
Protect after finding that hinged sealing ring lost efficacy, carry out filling polyurethane immediately and realize sealing property reparation, it is ensured that push-bench construction peace
Entirely, reliably.Traditional hinged sealing ring is sealed pressurize by this utility model, and grease seal combines, and increases again polyurethane pre-
Anti-measure, it is ensured that push-bench is in the safety of construction of underground tunnel, reliability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Sequence number in figure: 1 be anterior shield assembly, 2 be tail shield, 3 be sealed groove, 4 be hinged sealing ring, 5 for manual oiling system
System, 6 it is polyurethane system.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
See Fig. 1, a kind of push-bench hinge seal device, including sheathed hinged anterior shield assembly and tail shield, total with anterior shield
Become and offer two seals groove on the tail shield outer wall of correspondence, in described two seals groove, be provided with hinged sealing
Enclosing, gluing, sealing is all mated with anterior shield assembly inwall in the outer end of the hinged sealing ring of twice, the sealing between the hinged sealing ring of twice
It is provided with and communicated with manual injection system, the design of the hinged sealing ring of twice of the present utility model in cavity, compensate for anterior shield assembly
Produce different gaps from tail shield when travel direction adjusts, determine that the parameter of hinged sealing ring elastic deformation amount is arranged, thus with
More superior cost performance meets the effect of sealing；Additionally, by by the manual oiling being arranged between the hinged sealing ring of twice
System, it is ensured that hinged sealing ring works under more excellent working condition.
In order to ensure the security performance after hinged sealing ring lost efficacy, at described anterior shield assembly afterbody and corresponding set
If tail shield between be additionally provided with polyurethane system, described polyurethane system is positioned at the outside of hinged sealing ring, by hinge
Connect and polyurethane system is set outside sealing ring, play double protection measure, it is ensured that after finding that hinged sealing ring lost efficacy, enter immediately
Row filling polyurethane realizes sealing property reparation, it is ensured that push-bench construction safety, reliable.This utility model is by traditional hinged close
Seal seals pressurize, and grease seal combines, and increases again polyurethane preventive measure, it is ensured that push-bench is at construction of underground tunnel
Safety, reliability.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.One's own profession
Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Simply principle of the present utility model, on the premise of without departing from this utility model spirit and scope, this utility model also has respectively
Planting changes and improvements, these changes and improvements both fall within the range of claimed this utility model.This utility model requirement
Protection domain defined by appending claims and equivalent thereof.
