Abstract
The utility model relates to a secondary pressurizing mechanism for a rotor-type wet spraying machine, in particular to an improved air pressure conveying device. A secondary pressurizing conveying device of a wet spraying machine in the prior art is improved, the secondary pressurizing mechanism comprises an outer sleeve, an inner opening conic structure, an output end ring trapezoid structure, an inner sleeve, an O-shaped sealing ring and an air inlet hole, wherein two ring grooves are arranged on the two ends of the outer sleeve, the inner sleeve is sleeved on an inclined hole structure which has a 45-degree angle in the output direction and a 5-degree included angle in the axial direction, the O-shaped sealing ring is arranged between the inner sleeve and the outer sleeve, and the air inlet hole is connected with an air inlet tube. By the aid of the second pressurizing mechanism, tube plugging in the spraying process can be effectively avoid, so that concrete can be conveyed in a spiral manner, the friction between the concrete and the inner wall of a conveying tube is reduced, the problems in the operating process of a wet spraying machine that the spray distance is too short due to insufficient pressure, the spray is not homogeneous due to unstable pressure, the additive and the concrete are not evenly mixed and the spray quality is poor are solved, additive and concrete can be sufficiently mixed, conveying is smooth, and the spraying distance is longer.
Description
One, technical field
The utility model relates to a kind of concrete spraying equipment member, belongs to spray concrete construction equipment technical field.Particularly relate to a kind of wet shot machine secondary pressing mechanism.
Two, background technology
In engineering constructions such as mine working, railway and highway tunnel, water conservancy culvert, each underground engineering, highrise building foundation ditch, military engineering; Extensively adopt this international advanced supporting method of combined bolting and shotcrete, concrete (concrete) spraying machine is the capital equipment of this operation.Concrete sprays to be divided into usually does spray, tide spray and three kinds of wet shots.Dry spraying machine and watering jet eductor exist that dust is big, resilience is many in order to avoid in the present domestic spray concrete construction, of poor quality, noise greatly, problem such as workman's construction environment is abominable; Progressively begin to adopt the operation of wet shot machine spray concrete, the inexorable trend of wet shot machine spray concrete operation will becoming spray concrete industry development.
At present, the development of China's wet shot machine technology is still waiting to improve with abroad comparing, and performance is advanced inadequately, and scale waits to enlarge.Especially insufficient pressure in wet shot machine course of injection is prone to problems such as plugging in the concrete course of injection.Therefore this seminar is based on national conditions according to industry development trend; In conjunction with site operation demand and problems appeared in construction; The secondary pressing mechanism of having invented rotator type wet shot machine has solved the problem that exists in the shotcrete construction well, will give play to important function to the spray concrete industry development of China's infrastructure construction.
Three, utility model content:
The utility model requires a kind of rotator type wet shot machine secondary pressing mechanism of protection, comprises overcoat (9), air inlet port (8), sealing ring (7), interior cover (6), it is characterized in that adopting between described interior cover (6) and the overcoat (9) seal ring structure of sealing ring (7); Interior cover (6) medial launder is air inlet port (8); It adopts annular trapezium structure, and wind is got into by air inlet port (8), and interior cover (6) hole is a pyramidal structure; The output aperture that communicates with air inlet port is opened inclined hole along outbound course, and with 5 °～15 ° angles are axially arranged.Overcoat (9) adopts metal material, and respectively there is a cannelure at two ends.Overcoat (9) and interior cover (6) output adopt the trapezium structure that matches.
The utility model adopts the secondary pressing mechanism, and secondary pressing mechanism overcoat adopts metal material, and both sides have two cannelures, are used for being connected with material conveying mechanism with discharging opening.Interior cover and overcoat adopt seal ring structure, prevent that air pressure relief and concrete from getting into.Interior cover adopts alloy steel, has strengthened scuff resistance, and medial launder adopts annular trapezium structure; Help the circulation output of blast; The output aperture is opened inclined hole according to outbound course, and with 5 ° of angles are axially arranged, concrete can spiral under the effect of blast be exported; Reduce the friction of concrete and carrier pipe, improve transfer efficiency.
The utility model design simple in structure is ingenious, and the concrete that solves the existence in the construction well is low at discharge pressure, and concrete sprays problem technical problems such as unstable, that mixing is inhomogeneous, efficient is low.
