Description
Technical field
The utility model is related to push-bench technical field, more particularly to a kind of push-bench fast-open type sealing rear door.
Background technology
When pipe jacking tunnelling machine works, soil, rock are contacted using front cutterhead blade, cutter can produce excessive wear, be
Prevent because of excessive tool wear, not changing in time and destroying cutter head structure, influence project progress or generation security incident, at this moment
It is necessary to open the cabin and carries out the inspection and replacing of cutter.When cutterhead position is on the poor stratum of Important building or autostability
When, normal pressure open the cabin tool changing or maintenance can cause face cave in even ground cave in, security risk is very big, it is therefore desirable to pressure
Open the cabin tool changing.Therefore, it is proposed that a kind of push-bench fast-open type seals rear door.
Utility model content
Main purpose of the present utility model is to provide a kind of push-bench fast-open type sealing rear door, the utility model structure
It is simply, with pressure in cabin to be prevented from, into personnel's maintenance and block removing safety is improved while water, mitigating the work load of staff,
Shorten working hours, the problem of effectively can solving in background technology.
To achieve the above object, the technical scheme that the utility model is taken is：
A kind of push-bench fast-open type seals rear door, including doorframe and door-plate, and the door-plate is connected to by hinge assembly
On doorframe, the door-plate is used for fixed handle assembly provided with four groups, and the handle assembly includes handle and pressing plate, described
Hand includes Internal handle and outer handle, and the Internal handle and outer handle are co-axially located inside and outside door-plate, the Internal handle one
End is provided with pressing plate.
Further, hinge assembly is hinge part.
Further, the handle assembly is provided with four groups, and four groups of handle assemblies are evenly distributed on door-plate in a ring.
Further, the door-plate is provided with observation window.
Further, the contact surface of the door-plate and doorframe is provided with sealing ring.
Further, the Internal handle and outer handle are bolted on door-plate.
Compared with prior art, the utility model has the advantages that：The utility model is simple in construction, with pressure in cabin
It is prevented from, into personnel's maintenance and block removing safety is improved while water, mitigating the work load of staff, shortening working hours.

Embodiment
For make the utility model realize technological means, creation characteristic, reached purpose and effect be easy to understand, below
With reference to embodiment, the utility model is expanded on further.
As shown in Figure 1-2, a kind of push-bench fast-open type sealing rear door, including doorframe 1 and door-plate 2, the door-plate 2 passes through
Hinge assembly 3 is connected on doorframe 1, and the door-plate 2 is used for fixed handle assembly provided with four groups, and the handle assembly includes
Handle and pressing plate 2, the handle include Internal handle 4 and outer handle 9, and the Internal handle 4 and outer handle 9 are co-axially located at door-plate 2
Inside and outside, described one end of Internal handle 4 is provided with pressing plate 8.
A kind of push-bench fast-open type sealing rear door of the utility model, makes push-bench be in band by the sealing of front and rear hatch door
Working condition is pressed, closed cabin had both been prevented into water in push-bench driving, while when overhauling cutterhead or block removing, staff only uses
By rotating outer handle 9, you can quickly enter from rear cylinder hatch door, then by rotating cylinder hatch door after the closing of Internal handle 4, due to preceding
Sealing hatch door is turned off making one to be under ambient condition with pressure afterwards, then is overhauled by rotary handle opening placket hatch door, locates
In avoiding caving in for soil layer under environment with pressure.
Wherein, hinge assembly 3 is hinge part, and general part installation and removal are convenient, using simple.
Wherein, the handle assembly is provided with four groups, and four groups of handle assemblies are evenly distributed on door-plate 2 in a ring, can
Door-plate 2 is sufficiently secured within doorframe 1.
Wherein, the door-plate 2 is provided with observation window 7, convenient observation.
Wherein, the contact surface of the door-plate 2 and doorframe 1 is provided with sealing ring 6, for sealing.
Wherein, the Internal handle 4 and outer handle 9 are bolted on door-plate, are easy to connect and are dismounted.
Some one exemplary embodiments of the present utility model are only described by way of explanation above, undoubtedly, for
One of ordinary skill in the art, can be with a variety of in the case of without departing from spirit and scope of the present utility model
Mode is modified to described embodiment.Therefore, above-mentioned accompanying drawing and description are inherently illustrative, should not be construed as
Limitation to the utility model claims.
