The flume of existing farmland water conservancy works extensively adopts concrete prefabricated U type canal lining in the water channel sclerosis operation less less than 2 meters section suitable for reading, it is more convenient and quick to construct.Chinese patent " 96241039.9 1 kinds of new concrete molding component machines " and Chinese patent " 97233982.5 full-automatic concrete molding component machine " are now advanced concrete U type canal lining production equipments, all adopt the vertical moulding box of installing on base or frame, reinforced in vertical moulding box, in vertical moulding box, carry out the extrusion modling on the section.But there are some problems in this mode of production: owing to adopted vertical tight mould, charging and releasing process, complicated operation, efficient is low, when pressure forming machine pushes at section, the packing of concrete U type canal lining is inhomogeneous, during the demoulding, concrete is still unhardened, and the strength of materials is low and cause yield rate to be difficult to improve.
The purpose of this utility model be design a kind of can continuous cloth, the device of extruding fast, continuous production U type canal lining that yield rate is high.
The utility model mainly is made of charger, three roller cloth parts and forcing press.Charger hopper mouth is aimed at the dancer of three roller distribution devices and the gap between the compression roller, makes things convenient for the adding of raw material, and both fix on a plane; In the conplane vertical lower of compression roller is registration roller, and they form the cloth parts, is positioned at the top of electromotive roller rod transmission device.Compression roller, dancer are above the lining mould, and registration roller is below the lining mould.The electromotive roller rod has driven the transmission device that is fixed on the base, is the lining mould of walking with transmission device continuously on the transmission device, and three roller clothes are realized continuous concrete speading, leveling and compacting on the lining mould.Pressure forming machine is positioned at after the cloth parts, and it is partly formed by two, and a part of have last die head above electromotive roller rod transmission device, another part thereunder, at the bottom of the mould of flexible successively bracing or strutting arrangement and the charged machine that shakes, production line is from its middle passing.When the lining line is gone on the elastic device below the pressure forming machine, the last die head of pressure forming machine moves downward, be affixed on the lining mould through on the concrete of certain compacting, drive concrete and move downward together with the lining mould, arrive on the bed die of the charged machine vibration that shakes, last die head is driven by hydraulic press, after after a while vibration and extruding, hydraulic press drive upward die head is mentioned, and the lining mould is also lifted by resilient supporting unit with last die head simultaneously, and is transported to next maintenance operation by transmission device.
Its structure form basically identical at the bottom of the lining mould of above-mentioned utility model, last die head, the mould, all corresponding with U type canal lining product.
The spiral reamer that charger of the present utility model can be driven by the reducing motor of adjustable speed constitutes, and is respond well.
Die head has detent projection on the pressure forming machine of the present utility model, U type canal lining can be pressed into the reeded shape in the back side.
Lining mould of the present utility model is a grooved, and grooved lining mould bottom surface is a curved surface, and there is a grade limit on both sides.
The course of work of flowing water production described in the utility model is such, a plurality of lining moulds 9 are walked from left to right, when the position of feeding device 2 that passes through adjustable speed and curved surface distribution device 5, be covered with concrete on the lining mould of U type canal lining through paving and leveling and compacting, when lining mould 9 was walked the position of canal pressure forming machine 6, behind the location, the last die head 8 of pressure forming machine moved downward, be attached on the U type canal lining lining mould 9 of cloth honest material, and move downward together.When reaching the position of bed die, upper and lower mould will serve as a contrast mould together with further vibration and compacting of concrete material, and can have projection on last die head 8, and U type canal lining is pressed into the reeded structure in the back side.Go up die head 8 then and lift, resilient supporting unit also will serve as a contrast the lining mould of mould and compression moulding and the canal lining lifts, and cooperates with other transmission device will serve as a contrast mould and U type canal and serve as a contrast and deliver to next maintenance operation.This streamline of just having finished concrete U type canal lining is produced continuously.
The utility model can make continuous cloth be squeezed in fast on the lining mould of concrete U type canal lining and realize that continuous concrete surface paving and leveling and compacting operation have been realized the continual continuous mode of production.The large-area feed way of employing level, horizontal vibration and extruding, make simple to operation, reliable and stable, the production efficiency height.The concrete U type canal produced lining packing is even, and can the production back side has the concrete U type canal lining of groove, reaches the saving material, reduces the purpose of transport power.
