Abstract
The utility model discloses a pressurized balance shield machine model for muddy water. The model is integrally arranged on a frame, and comprises a tool bit, a tool bit rotator, an automatic assembly device of duct piece, a real-time backfill grouting pipe, an annular keeping system, a fine tuning jack, a propel jack, a hydraulic device and a control chamber, wherein housings are just arranged at two parts namely the tool bit and the tail part of the control chamber in the model; the tool bit is provided with a rotary driving device; a light device is arranged on the real-time backfill grouting pipe; and the rotary driving device and the light device are connected with a power supply through a control switch. The arrangement of the model structure is simplified by removing complications on the basis of reflecting the main structure and flow of the shield machine; the audience can comprehensively understand the entire structure by the arrangement of a part of housing; and the audience can clearly and intuitively understand the working principle and the main structure by combining rotation of the tool bit and a light module.
Description
Technical field
The utility model relates to a kind of model of showing muddy water adding pressure type balance shield machine principle of work and primary structure thereof.
Background technology
Shielding tunnel excavator is called for short shield machine.Be a kind of special engineering machinery of tunnel piercing, be widely used in the Tunnel Engineering such as subway, railway, highway, municipal administration, water power.Have automaticity high, save that manpower, speed of application are fast, controllably face sedimentation when cavitation, weatherproof, excavation, reduce the ground influence of building and do not affect the characteristics such as water surface traffic when excavating under water, in the situation that the tunnel line is long, buried depth is larger, with more economical rationality of shield machine construction.
The basic functional principle of shield machine is exactly that a cylindrical steel assembly excavates soil while pushing ahead along the tunnel axis.The housing of this cylinder component is shield, and it plays a part temporary supporting to the also unlined Tunnel Section of excavating, and bears the pressure of soil layer on every side, sometimes also bears ground water pressure and with underground water gear outside.The operations such as excavation, casting, lining cutting are carried out under the shielding of shield.
Muddy water adding pressure type balance shield machine is to stablize excavation face by pressurization muddy water or mud (being generally bentonite suspension), there is a seal diaphragm its cutterhead back, and form the muddy water chamber between the excavation face, the inside has been full of mud, the excavation earth material mixes by steam piano with mud and is transported to separation plant outside the hole, and mud is reused after separation.
Modern shield excavation machine light harvesting, mechanical, electrical, liquid, sensing, infotech are in one, have the functions such as the excavation cutting soil body, conveying soil quarrel, assembly unit tunnel-liner, the correction of measurement guiding, relate to the multi-door subject technologies such as geology, building, machinery, mechanics, hydraulic pressure, electric, control, measurement, its complex structure, principle of work is more abstract, lack intuitively teaching means, in Popular Science Education, be difficult to allow the people understand.How simplifying literary writing by leaving out superfluous words on the basis of reaction primary structure and flow process, allow spectators understand its principle of work and primary structure thereof clear and intuitively, is the problem that scientific and technological modelling will be faced.
Summary of the invention
In order to solve above-mentioned drawback, technical problem to be solved in the utility model is, a kind of scientific and technological model of showing muddy water adding pressure type balance shield machine principle of work and primary structure thereof is provided, and makes the learner can understand intuitively corresponding knowledge.In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of muddy water adding pressure type balance shield machine model, it is characterized in that, described model integral body places on the vehicle frame, comprises cutter head, cutter head spinner, section of jurisdiction automatic assembling device, real-time backfill grouting pipe, annular retaining system, fine-adjustment jack, propelling lifting jack, hydraulic means and pulpit; Described model only two parts of afterbody in cutter head and pulpit arranges shell; Described cutter head is provided with rotating driving device, and described real-time backfill grouting pipe is provided with lighting fixture, and described rotating driving device is connected gauge tap with lighting fixture and connects power supply.
The beneficial effects of the utility model are, model structure is arranged on the basis of reflecting shield machine primary structure and flow process and simplifies literary writing by leaving out superfluous words, the part shell is arranged so that spectators can have overall understanding to its one-piece construction, rotate and light modules in conjunction with cutter head, can allow spectators understand its principle of work and primary structure thereof clear and intuitively.
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
Referring to accompanying drawing, reflect a kind of concrete structure of the present utility model, a kind of muddy water adding pressure type balance shield machine model, it is characterized in that, described model integral body places on the vehicle frame 8, comprises cutter head 1, cutter head spinner 2, section of jurisdiction automatic assembling device 3, real-time backfill grouting pipe 4, annular retaining system 5, fine-adjustment jack 6, advances lifting jack 7, hydraulic means 9 and pulpit 10; Described model only two parts of afterbody in cutter head 1 and pulpit 10 arranges shell 11; Described cutter head 1 is provided with rotating driving device, and described real-time backfill grouting pipe 4 is provided with lighting fixture, and described rotating driving device is connected gauge tap with lighting fixture and connects power supply.
The gauge tap of closing, described cutter head 1 rotation, this moment, the lighting fixture of described real-time backfill grouting pipe 4 was lighted display lamp light stream journey, allowed spectators understand intuitively the operation logic of shield machine.
