Abstract
The utility model relates to a diameter changing inner mould for forming large diameter steel reinforced concrete pipes, comprising inner mould barrel body with a gap (4). The barrel body is provided with two equidistant movable pull corners (2) in a welding way, and the two pull corners are respectively hinged with two connecting plates (3) which are hinged with a power pull rod (5) whose end part is fixedly provided with a movable strip plate (1). The inner mould is used for producing large diameter steel reinforced concrete pipes, and the utility model has the advantages of less equipment investment, low energy consumption, no waste slurry and no nuisance. Because the utility model uses power and diameter changing modes to make demoulding, the bulky manual work is saved, and the utility model can be used for processing a plurality of large diameter pipes.
Description
The utility model relates to large diameter concrete pipe shaping mould, particularly diameter, and (be particularly suitable for producing φ 1000mm-φ 5000mm, length is 2000mm greater than the reducing internal mold of 1000mm pipe of concrete; 2500mm; 3000mm; 5000mm) heavy caliber concrete drain tile.
At present, centrifugal process is mostly adopted in the large diameter concrete pipe moulding, and its shortcoming is: investment is big, energy consumption is high, noise is big, throw away a large amount of useless mortar in the big tuber forming process, contaminated environment, the second pipe of cement factory is an example with Beijing, the mortar sediment of producing 100 kilometers pipe of cements generations is up to more than 3000 tons, become a great problem of enterprise, and the pipe of concrete presentation quality of making is poor, the outer wall ixoderm, wall reveals stone and runs slurry, therefore, is necessary to provide a kind of novel mould.
The purpose of this utility model provides that a kind of investment is little, and energy consumption is low, and is easy to operate, and the concrete reinforced pipe inside and outside wall after the moulding is smooth, external pressure strength is higher than centrifugal process.
For achieving the above object, the utility model is by the following technical solutions: the reducing internal mold equipment that is used for moulding heavy caliber concrete reinforced pipe comprises: the internal mold cylindrical shell that has breach, the angle is drawn in two equidistant activities of welding on the cylindrical shell, two draw the angle hinged with two connecting plates respectively, two connecting plates and power pull bar are hinged, and tie rod end is fixed a movable batten.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1: a kind of reducing internal mold front view that is used for moulding heavy caliber concrete reinforced pipe
The side view of Fig. 2: Fig. 1
Fig. 3: the enlarged drawing of A among Fig. 2
Among Fig. 1, Fig. 2, Fig. 3,4 have the internal mold cylindrical shell of breach, and two equidistant activities of welding draw angle 2, two to draw the angle hinged with two connecting plates 3 respectively on the cylindrical shell, and two connecting plates and cylinder plunger primary push rod 5 are hinged, and a movable batten 1 is fixed in the primary push rod end.Among the figure, 6 is hydraulic cylinder, 7 be pin except the cylinder plunger primary push rod, can also use power pull bars such as electric pushrod, screw thread pull bar.
Operating process: this internal mold can be used with the external mold with monolateral opening linkage locking structure, before the demoulding, movable batten and internal mold circle wall connect flat, draw the angle parallel, when connecting plate was spent less than 180 owing to the effect of hydraulic cylinder, the batten on the internal mold was drawn out of, and the internal mold girth is contracted, after the length that the internal mold girth is shortened multiply by 1/ (π), the just interior reduced length of mode diameter.Otherwise hydraulic cylinder advances, because the connecting plate effect draws the angle to be open, connecting plate becomes 180 degree, and batten is filled in internal mold cylindrical shell indentation, there and restored.Internal mold generally got final product the demoulding according to pipe diameter size and jelling time difference at 30-120 minute, prolong demould time and can guarantee the smooth of bell and spigot, and can eliminate pore and crackle.
The utility model advantage: small investment, energy consumption is low, for example producing φ 2600mm, length 3000mm pipe of concrete, hydraulic variable diameter vibration moulding only needs 7 kilowatts (originally needing 132 kilowatts), there is not useless mortar, do not have public hazards, owing to adopt hydraulic variable diameter, external mold adopts monolateral opening locking, inside and outside moulding/demoulding is easy, saves heavy muscle power Work, all work only needs 3-4 people to finish, and can be used for producing the drainpipe of bell and spigot, also can produce the tongue and groove drainpipe, fixable type is produced, also can flow-type production, after each production cycle, can continue, the pipe of newborn output is in original place steam curing, or do not have the steam natural maintenance.
Claims (2)
1, a kind of reducing internal mold equipment that is used for moulding heavy caliber concrete reinforced pipe, it is characterized in that: it comprises: the internal mold cylindrical shell (4) that has breach, angle (2) is drawn in two equidistant activities of welding on the cylindrical shell, two draw the angle hinged with two connecting plates (3) respectively, two connecting plates and power pull bar (5) are hinged, and tie rod end is fixed a movable batten (1).
2, by the described reducing internal mold equipment that is used for moulding heavy caliber concrete reinforced pipe of claim 1, it is characterized in that: described power pull bar is the push rod of cylinder plunger.
