Abstract
The utility model discloses an additive inlet structure for a shield excavation machine, which is mainly applied to the shield excavation machine in the tunnel construction field and includes an inlet mounting seat (1), an O-shaped sealing ring (2), a middle supporter (3), a socket cap screw (4), a hexagon socket head screw (5), a pressure-bearing plate (6), an unidirectional protective plate (7), a pressing plate (8) and a short pipe (9). The device prevents the slags from blocking the inlet and enables the additive to be injected smoothly by using the elasticity of the O-shaped sealing ring (2) and the liquid unidirectional trafficability of a combination of the pressure-bearing plate (6), the unidirectional protective plate (7) and the pressing plate (8). The device is novel in conception, simple in structure and convenient in mounting and dismounting and solves the problem of obstruction of the additive inlet in the shield construction process.
Description
Technical field
The present invention relates to the realm of building construction, be mainly used in the shield machine in the constructing tunnel.
Background technology
In shield construction, additive is improved at the soil body, sealing, anti-attrition, prevent that aspects such as mud lining from playing crucial effects, because the additive inlet contacts with the face soil body, very easy the obstruction, when taking place to stop up as the additive inlet, the injection of additive will be had a strong impact on, and then influence the shield machine driving speed, the stratum comparatively complicated at geological condition can have a strong impact on as cutter, cutterhead, the application life of parts such as conveying worm, thereby increase the shield machine construction cost, cause constructional difficulties, at present, at home in the shield-tunneling construction, exist much and stop up because of the additive inlet, have a strong impact on the case of shield machine construction, how to solve the difficult problem that the shield machine additive port is stopped up easily, become the problem that each shield-tunneling construction unit generally is concerned about.
Summary of the invention
The utility model provides a kind of shield machine with additive inlet structure, can solve current shield machine additive inlet effectively blocking problem takes place easily.
This structure is made up of inlet mount pad (1), O RunddichtringO (2), intermediate support (3), hexagon socket cap head screw (4), hexagon socket countersunk flat cap head screw (5), bearing plate (6), unidirectional protected apron (7), pressing plate (8) and short tube (9), bearing plate (6), unidirectional protected apron (7), pressing plate (8) are fixed on the intermediate support (3) successively by hexagon socket countersunk flat cap head screw (5) sequentially, intermediate support (3) is fixed on the inlet mount pad (1) by hexagon socket cap head screw (4), and O RunddichtringO (2) tightly is enclosed within on the intermediate support (3); O RunddichtringO (2) and unidirectional protected apron (7) are by having certain elasticity and the abrasion resistance material is made; Have the logical crack that several cross the center on the unidirectional protected apron (7); Have the identical or different through hole of several shapes on the bearing plate (6); Intermediate support (3) matrix directly upwards is equipped with several through holes, and lead to the hole site is identical with installation O RunddichtringO (2) position; Bearing plate (6), unidirectional protected apron (7), the assembly of pressing plate (8) has the unidirectional trafficability characteristic of liquid, when the face soil body compresses unidirectional protected apron (7), when desire enters additive injecting structure inside by the logical crack on the unidirectional protected apron (7), unidirectional protected apron (7) is pressed on the bearing plate (6), stop the soil body to enter in the additive ascending pipe, stop up the additive inlet, when injecting additive, the additive that has certain pressure can back down unidirectional protected apron (7) by the through hole on the bearing plate (6) easily and go up the opening of being made up of the logical crack at the center of mistake, enters face.O RunddichtringO (2) tightly is enclosed within on the intermediate support (3), and be installed on the position of intermediate support (3) matrix radial direction through hole, because O RunddichtringO (2) tightly is enclosed within on the intermediate support (3), the radial direction through hole that can stop dregs to pass through on intermediate support (3) matrix effectively enters additive injection device inside, stop up the additive inlet, the additive that has certain pressure can be easy to strut O RunddichtringO (2) and enter face; O RunddichtringO (2) and unidirectional protected apron (7) require to have certain elasticity and abrasion resistance, wash O RunddichtringO (2) open and unidirectional protected apron (7) enters face with the additive that stops the soil body to enter in the additive inlet structure better and conveniently to have pressure, simultaneously, guarantee that it has higher application life; Unidirectional protected apron (7) was gone up the logical crack at center, was the passage of additive, unidirectional protected apron (7) go up the center of each logical crack by unidirectional protected apron (7) be for guarantee additive by the time have a bigger opening; Through hole on the bearing plate (6) is the injection channel that additive leads to face; Intermediate support (3) matrix directly upwards is equipped with several through holes, these holes equally also are the injection channels that additive leads to face, lead to the hole site is with that O RunddichtringO (2) position is installed is identical, enters in the additive injection device to stop the soil body to pass through several through holes that intermediate support (3) matrix directly makes progress effectively.
The utility model provides a kind of simple in structure, low cost of manufacture, additive inlet structure that reliability is high, and this structure can solve additive inlet blocking problem effectively, and then improves the shield machine operating efficiency, reduces construction cost.

The specific embodiment
Shield structure in the present embodiment comprises inlet mount pad (1), O RunddichtringO (2), intermediate support (3), hexagon socket cap head screw (4), hexagon socket countersunk flat cap head screw (5), bearing plate (6), unidirectional protected apron (7), pressing plate (8) and short tube (9) with additive inlet structure as shown in Figure 1.Bearing plate (6), unidirectional protected apron (7), pressing plate (8) are fixed on the intermediate support (3) successively by hexagon socket countersunk flat cap head screw (5) sequentially, intermediate support (3) is fixed on the inlet mount pad (1) by hexagon socket cap head screw (4), O RunddichtringO (2) tightly is enclosed within on the intermediate support (3), and O RunddichtringO (2) and unidirectional protected apron (7) adopt acrylonitrile-butadiene rubber to make; Have 4 logical cracks of crossing the center on the unidirectional protected apron (7); Have 4 scallop holes on the bearing plate (6); Intermediate support (3) matrix directly upwards is equipped with orthogonal 4 through holes, and lead to the hole site is identical with installation O RunddichtringO (2) position; The undersized of O RunddichtringO (2) makes O RunddichtringO (2) can tightly be enclosed within 4 aperture position places of intermediate support (3) matrix, and has certain elasticity constrictive force in intermediate support (3) matrix size.When need when face injects additive, the additive liquid that has pressure by 4 scallop holes having on 4 through holes on intermediate support (3) matrix and the bearing plate (6) respectively with O RunddichtringO (2), unidirectional protected apron (7) backs down, and then be injected on the face, when not injecting additive, the soil body of face is pressed in O RunddichtringO (2), on the unidirectional protected apron (7), because bearing plate (6) and the supporting role of intermediate support (3) and the elasticity constrictive force of O RunddichtringO (2), stop the soil body to enter in the additive inlet structure, avoid the soil body to enter in the additive inlet structure and stop up; The degree that compresses that contacts with the additive inlet for the soil body that reduces face; additive inlet protective device (11) is set before additive inlet structure; additive inlet protective device (11) and cutterhead panel (10), comprise that inlet mount pad (1) and short tube (9) all adopt with mount pad (1) and be welded to connect that weld seam does not show on figure.
