Description
Technical field
The present invention relates to an a kind of machine stress fluctuation control method and special-purpose stress fluctuation control convenience thereof of twining, belong to Prestressed concrete cylinder pipe and twine a machine Stress Control field.
Background technology
Prestressed concrete cylinder pipe (Prestressed Concrete Cylinder Pipe) is called for short PCCP; Be that the cement concrete tube core that has steel cylinder twines compressor wire; Spraying the protective cover that forms densification with cement mortar again, is the novel water delivery tubing of the composite structure of steel plate, cement concrete, high tensile steel wire and cement mortar different materials composition.Twining silk is the crucial production process of Prestressed concrete cylinder pipe, promptly high tensile steel wire according to design proof stress value, the even screw-shaped of pitch according to the rules is wrapped in PCCP tube core outside.National Specification steel wire stress fluctuation scope should be controlled in design value ± 10%, and the compressor wire stress fluctuation surpasses the inherent quality that specialized range will influence product.The twining a machine and under the wire feed rate that limits, can reach this requirement of present domestic industry production, but because of being restricted, wire feed rate cause the production efficiency that twines silk lower, and therefore, for guaranteeing production efficiency, every manufacturing line is equipped with two usually and twines a machine.Along with water conveying and diverting engineering twines the renewed attention of a stress to the PCCP tube core, the control requirement that has improved high tensile steel wire stress fluctuation scope especially can stress to require steel wire stress fluctuation scope to be controlled in engineering stress value ± 5% usually.An existing machine that twines does not satisfy such requirement basically, does some improvement even some twines a machine, can barely be controlled at ± 5% in, but the wire feed rate that twines a machine can not improve, production efficiency is very low, can not satisfy the demand of production.The reason that causes the problems referred to above is the mechanical equipment precision that prior art can not economic solution twines a machine, twines steel wire in the process and is answering overlapping slip on the wheels and steel wire to occur in the wire feed process that reason such as fluctuation causes.
The vertical principle that adds to high tensile steel wire stress in the process in advance that twines of Prestressed concrete cylinder pipe is; PCCP tube core velocity of rotation with twine a machine and answer that the wheels velocity of rotation is different to make it to produce velocity contrast; Rely on both velocity contrasts to force high tensile steel wire to be strained continually and steadily, cause high tensile steel wire to produce design control tensile stress.Twine thread machine application state figure such as Fig. 4 in the known technology; High tensile steel wire 26 is coiled in signal such as the Fig. 5 that answers on the wheels 27.
Generally, wheels 7～8 circles are answered in the high tensile steel wire coiling.When PCCP tube core 24 when answering wheels 20 to rotate simultaneously by design-calculated speed, high tensile steel wire 26 is tightened up and produces tensile stress.Along with the rotation of PCCP tube core 24, high tensile steel wire 26 by design-calculated pitch equably helically be wrapped on the PCCP tube core 24.The rotation of PCCP tube core 24 relies on the rotation of chassis 25 motors to drive, and answers wheels 20 to rotate and relies on the rotation of answering force motor to drive.Answer the velocity of rotation of wheels 20 to preestablish; The base plate electric machine rotative speed is pressed the control of design-calculated velocity contrast by preset program; The velocity contrast variation causes that the fluctuation of high tensile steel wire tensile stress is transformed to electric signal through sensor 22 and feeds back to base plate electric machine; Base plate electric machine is regulated velocity of rotation by preset program, makes high tensile steel wire continue to be in to meet the tension state that rises of engineering stress value.Twine a machine and answer the velocity of rotation decision wire feed rate of wheels 20.In the process of answering wheels 20 to rotate to continue wire feed forward, answer the high tensile steel wire overlapping on the wheels can be suddenly to front slide, sensor 22 converts this situation into electric signal transmission and gives base plate electric machine, and base plate electric machine speedup again rotates the velocity contrast of keeping former setting; After the base plate electric machine speedup, moment finishes to answer the steel wire of wheels to slide, and sensor converts this situation into electric signal transmission again and gives base plate electric machine, and base plate electric machine slows down and keeps the velocity contrast of former setting.This situation can occur repeatedly; Switching process also can occur repeatedly; Yet electric signal generation and transmission, base plate electric machine speedup are slowed down and are all had response lag phenomenon significantly compared to steel wire moment slip; Cause the PCCP tube core and answer the rotary speed difference of wheels to be difficult to keep continually and steadily, cause the high tensile steel wire tensile stress transient fluctuation to occur by design value.Simultaneously, if the fluctuating range of answering the wire feed rate quickening of wheels can aggravate high tensile steel wire stress.Therefore, be the scope that the fluctuation National standard of guaranteeing high tensile steel wire stress is stipulated, just must reduce twining the wire feed rate that a machine is answered wheels, thereby reduce the production efficiency that twines silk at engineering stress value ± 10%.
Summary of the invention
According to above deficiency of the prior art; The technical matters that the present invention will solve is: provide a kind of can the solution to twine a stress instability, reduce a stress fluctuation amplitude that twines, guarantee product design and can improve wire feed rate, improve and twine a machine stress fluctuation control method of a production efficiency, and stress fluctuation control convenience special-purpose in twining a machine stress fluctuation control method is provided.
The technical solution adopted for the present invention to solve the technical problems is: a described machine stress fluctuation control method that twines; It is characterized in that: through two groups of stress fluctuation control setups are set between wheels and the track adjusting wheel carry out forward and backward twice and twine a stress adjusting control twining answering of a machine; Resistance shake track adjusting wheel is set between two groups of stress fluctuation control setups, on second group of stress fluctuation control setup pulling force sensor is installed.
A kind of special-purpose stress fluctuation control convenience of a machine stress fluctuation control method that twines; It is characterized in that: comprise the forward and backward two groups of stress fluctuation control setups between wheels and the track adjusting wheel of answering that are arranged on a machine that twines; Resistance shake track adjusting wheel is set between two groups of stress fluctuation control setups, on second group of stress fluctuation control setup pulling force sensor is installed.
Described first group of stress fluctuation control setup is base type stress fluctuation control setup, and second group of stress fluctuation control setup is suspension type stress fluctuation control setup.
Wherein:
Described base type stress fluctuation control setup; Comprise stress adjustment track adjusting wheel one and elasticity adjusting device; Elasticity adjusting device below is provided with base for supporting, stress adjustment track adjusting wheel one be arranged on answering between wheels and the resistance shake track adjusting wheel of a machine that twines and answer wheels with hinder shake compressor wire between the track adjusting wheel below.
