Abstract
The utility model discloses a middle air compensating device of a sprayed concrete conveying pipeline. The device comprises a mixed joint (2), an air compensating ring (3) and a connecting joint (6), wherein an accelerating agent inlet joint (5) and an air compensating opening joint (8) are fixed on the mixed joint (2); one end of the mixed joint (2) is connected with a concrete conveying pipe (1); and one end of the air compensating ring (3) is positioned at the interior of the mixed joint (2), and the other end of the air compensating ring (3) is fixedly connected with the mixed joint (2) and the connecting joint (6). The device is mounted in the middle position of the concrete conveying pipe and is far away from a spray nozzle, so as to reduce the weight of the spray nozzle; accelerating agents are conveyed through the accelerating agent inlet joint, air with pressure is conveyed through the air compensating opening joint; and besides, the mixing time of the accelerating agents and concrete is prolonged, the spray and support quality is improved, and the labor intensity of workers is reduced.
Description
Technical field
The utility model belongs to connecting leg road connecting device, being used for the shotcrete transfer line connects, the blast of postinjection concrete delivery pipe and interpolation accelerater, the support engineering that is widely used in railway, highway, mine, water conservancy and hydropower, urban construction, particularly, relate to the middle air compensation device of a kind of shotcrete ducting.
Background technology
At present during wet shot machine shotcrete, accelerater all adds at the shower nozzle place, the shower nozzle part is except the nozzle of shotcrete, also have accelerater hybrid ring and auxiliary device thereof, relatively heavier, when spraying, the operator need bear and spray antagonistic force and shower nozzle part and the concrete deadweight of delivered inside thereof that produces, therefore labour intensity is big, and operating difficulties, jet quality are difficult to control; Simultaneously, because the accelerater pipeline is connected on the shower nozzle, the time that accelerater mixes with cement concrete is shorter, and homogeneity is relatively poor, is difficult to guarantee the quality of support engineering; On the other hand, when fed distance was far away, when the initial stage, blast was not enough, cement concrete was little at the pressure of jet expansion, and exit velocity is low, and nozzle easily falls slurry, and resilience increases, and the shotcrete degree of firmness are low.
The utility model content
Technical problem to be solved in the utility model provides the middle air compensation device of a kind of shotcrete ducting, this device is installed in the midway location of concrete delivery pipe, away from nozzle, to change existing structure of nozzle form, increase simultaneously and replenish compressed-air actuated function,, prolong accelerater and concrete incorporation time to alleviate the weight of nozzle, improve the ejection supporting quality, alleviate working strength of workers.
The technical scheme in the invention for solving the above technical problem is:
Air compensation device in the middle of a kind of shotcrete ducting, comprise composite joint, mend vane, connector, be fixed with accelerater inlet union and wind-supplying mouth joint on the composite joint, described composite joint one end links to each other with concrete delivery pipe, benefit vane one end is positioned at the composite joint other end and captives joint with composite joint, mends the vane other end and captives joint with connector.This device is installed in the midway location of concrete delivery pipe, away from nozzle to alleviate the weight of nozzle, carry accelerater by the accelerater inlet union, air by wind-supplying mouth joint load-transfer device pressure, prolong accelerater and concrete incorporation time, improve the ejection supporting quality, alleviate working strength of workers.
Described benefit vane outer wall has two circular grooves, and one of them and accelerater inlet union are connected, and another and wind-supplying mouth joint are connected, and the circular groove place is equipped with and mends the group hole that the vane endoporus is connected.By mending two circular grooves that the vane outer wall is opened, can make composite joint be encircled into two leak free circular grooves with mending vane, be beneficial in the full annular groove, be full of the material that is transferred.
Described benefit vane is positioned on the composite joint in-to-in external cylindrical surface and has closure gasket groove, and closure gasket groove and be provided with seal ring between the composite joint inwall.
Described benefit vane endoporus is by mending vane and is positioned at composite joint in-to-in end to mending the taper hole that vane and connector bonded assembly end increase gradually.
Angle between the axis in the axis of described benefit vane endoporus and group hole is 0～90 °.
The described connector other end is connected with delivery pipe, and delivery pipe is connected with nozzle.
In sum, the beneficial effects of the utility model are: by the structure of additional pressurized air, accelerater is set on joint, its joint needn't directly be connected with nozzle, be installed in the midway location of concrete delivery pipe, increased concrete flow velocity, alleviate the weight of nozzle, increased accelerater and concrete incorporation time.
