Description
Technical field
The present invention relates to a kind of concrete production mold, in particular to a kind of concrete prefabricated round tube internal model structure.
Background technique
Existing concrete prefabricated round tube production mould is that folding is realized using lever power-assisted mode, and lever is connected in internal model
On.In operation, it needs worker to climb into internal model, pushes lever repeatedly with manpower, shrink internal model, so as to internal model and cement
Product disengages.Here there are four the problem of existing is main:
First is that large labor intensity, labor efficiency is low, needs worker to climb into the internal model of several meters of depths, again operating lever；
Second is that equipment efficiency of usage is low, need to carry out steam curing in technique after pouring, temperature is needed up to 80 DEG C or so
It waits for a period of time, worker, which just can enter, carries out mold-break operations in mould, and operation difficulty is big, and workload is also big；
Third is that safety is low, even if being cooling before die sinking and having waited a period of time, due to being semi-enclosed in mold
Space, so that cooling rate is very slow in mold, when general worker operates in entrance mold, it is still desirable to deposit by 50 ~ 60
DEG C high temperature, and the temperature on mold can be higher, and when operation is easy to appear fault and safety accident occurs；
Fourth is that work situation inclement condition, worker carries out work in 50 ~ 60 DEG C of high temperature and nonventilated environment, be it is painful,
It is unfavorable for physical and mental health.
Summary of the invention
The object of the present invention is to provide a kind of concrete prefabricated round tube internal model structures more to pacify so that die sinking is more convenient
It is complete reliable.
The object of the present invention is achieved like this: a kind of concrete prefabricated round tube internal model structure, including intervolved by plate and
At internal model cylinder, the plate head and the tail both ends closure, and through locking device be connected, the internal model cylinder is provided centrally with
Center bolt has been arranged in pairs multiple groups strut component on the center bolt, and one end of the strut component is hinged on center spiral shell
On bar, the other end is hinged on the inner wall of internal model cylinder, and the end for being hinged on the strut component on center bolt passes through transmission spiral shell
Box thread is connected on center bolt, and one be arranged in pairs group strut component moving direction is oppositely arranged.
A kind of concrete prefabricated round tube internal model opening/closing method opens locking device after concrete setting, drives mold top
The center bolt in portion rotates, and transmission nut drives strut component axially to move along center bolt, so that the strut group being arranged in pairs
Part moves toward one another, and strut component moves toward one another under hinged connection relationship, and the movement of vertical direction is converted to level side
To movement, realize strut component contraction so that internal model cylinder along plate both ends center position from junction to plate into
Row mould separating.
When the invention works, after concrete setting, locking device is opened, by rotation center screw rod, so that transmission spiral shell
Master tape moves strut component and axially acts along center bolt, and vertical direction conversion of motion is horizontal direction fortune by hinged connection relationship
It is dynamic, to pull internal model cylinder to shrink by strut component, realize demoulding.Compared with prior art, beneficial effects of the present invention
It is, the present invention cooperates strut component to realize strutting and shrinking for internal model cylinder by center bolt, to realize the mistake of demoulding
Journey when worker operation, only needs center of rotation screw rod, reduces the labor intensity of worker operation；No longer due to knockout course
It needs to be operated again to the temperature reduction in mold, improves production efficiency；Staff no longer needs to enter internal model cylinder
Inside is operated, and operational risk is reduced, so that operation is more safe and reliable；Meanwhile the present invention is by a pair of of strut component
Moving direction is oppositely arranged, so that each pair of strut component at work cancel out each other by axial force, no longer locates overall mechanism for a long time
In high-intensitive stress, the service life of internal each mechanism is extended, meanwhile, company of the present invention from plate both ends when demoulding
It meets place to start to be detached to the center of plate, relative to whole disengaging, the tension of surface contact surface is smaller, demoulds the side of being more easier
Just, product inner wall will not be caused to damage.The present invention can be used in the manufacture of concrete circular pipe.
In order to enable strut component is more uniformly stressed when shrinking, the strut component includes being fixed on transmission nut
The lifting seat of periphery, the periphery of the lifting seat are circumferentially evenly arranged with multiple inner hinges, and the inner hinge is through connecting rod and outside
Hinge is connected, on the inner wall of the fixed internal model cylinder of outer hinge.
In order to which the contraction of strut component is more convenient, the lifting seat selects outer-hexagonal nut, and inner hinge is fixed on outer-hexagonal
On nut end face, there are six the inner hinge, connecting rod, outer hinge are respectively provided with.
In order to which internal model cylinder board joints open and close more convenient, better tightness, the internal model cylinder upper plate material connection
Two mutually matched lozenges are processed at place, wherein opening up fluted on a lozenges, are provided with gasket in the groove.
In order to enable plate curling molding is more convenient, the both ends of the plate connection are respectively fixed with interior voussoir and outer wedge
Block, interior voussoir and outer voussoir inclined surface overlap to form spue line.
In order to enhance the stability and intensity of center bolt structure, the center bolt is connected through more screw rods with Duo Gen
Axis is composed, and screw rod is fixed together with connecting shaft interval.
In order to enable the rotation of center bolt is more convenient, dynamic input dress is fixedly connected at the top of the center bolt
It sets, the bottom of center bolt is connected on bearing block.
