Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
A kind of ductile iron pipe as shown in Figure 1 cuts loop device, comprise control panel, base 1, symmetrically arranged support roller and ring-cutting machine 2, support roller arranged in pairs is disposed in parallel on base 1, described ring-cutting machine 2 is arranged on base 1 end and outside support roller, described ring-cutting machine 2 comprises motor cabinet 3, motor 11 and grinding wheel 14, and described motor cabinet 3 one end is hinged on the carrier 4, the other end is connected with bearing 4 by power lift.Motor cabinet 3 under ring-cutting machine 2 with rotating shaft 13 for pivot overturns.
As a kind of preferred structure, described support roller comprises driving wheel 5 and from moving in turn 6, the support roller of described ring-cutting machine 2 side is driving wheel 5, and described driving wheel 5 is driven by power set.Ring-cutting machine 2 is positioned at driving wheel 5 side, and object is that driving wheel 5 side ductile iron pipe 15 is beated little, can reduce the consumption of grinding wheel 14 when cutting ring.
Described power lift is hydraulic jack 7, and piston and the motor cabinet 3 of described hydraulic jack 7 are hinged, hydraulic jack 7 cylinder body and bearing 4 hinged.Establish encoder 8 in described hydraulic jack 7 and at hydraulic jack 7, big orifice valve group 9 and little latus rectum valve group 10 be set on turnover oil pipe line, establish frequency converter 12 in the motor 11 of described ring-cutting machine 2, described big orifice valve group 9, little latus rectum valve group 10 are all connected with the PLC in control panel with frequency converter 12.The hydraulic valve that described big orifice valve group 9, little latus rectum valve group 10 are with integrated functionality combines, integrate flow speed control valve, check valve and three position four-way directional control valve, its difference part is that the latus rectum of big orifice valve group 9 is greater than the latus rectum of little latus rectum valve group 10, the two can choose the corresponding product of Beijing China moral hydraulic valve manufacturer production, also can choose the like product of other producers.
As shown in Figure 2, operation principle of the present invention is as follows: have the signal of telecommunication to drive big orifice valve group 9 hydraulic control oil cylinder 7 drive motor seat 3 to overturn (centered by rotating shaft 13) fast when cutting ring, when hydraulic jack 7 built-in encoder 8 detects that cutting grinding wheel 14 starts grinding wheel 14 electric rotating machine 11 close to during nodular cast iron pipe 15 setting value, disconnect big orifice valve group 9 simultaneously and connect little latus rectum valve group 10 and control motor cabinet 3 and overturn at a slow speed and start to cut.The frequency converter 12 controlling cutting rotation in cutting process detects motor 11 current signal, when cutting at the end of, motor current signal diminishes, by motor current signal diminish hydraulic control oil cylinder regain, cutting motor quits work simultaneously, automatically completes whole ring of cutting and operates.
The symmetrical support roller on base 1 is utilized to be held up by ductile iron pipe 15, Power Drive Unit drives driving wheel 5 that ductile iron pipe 15 is rotated, the position of the encoder 8 pairs of ring-cutting machines 2 in hydraulic jack 7 is utilized to detect when cutting ring, for the rising or falling speed of hydraulic control oil cylinder 7, to control the upset speed of ring-cutting machine 2, the frequency converter 12 in motor 11 is utilized to detect the moment size of cutting in ring process, change motor 11 size of current according to this, thus the action of hydraulic control oil cylinder 7, automatically complete whole ring of cutting and operate.
In sum, the present invention have simple and practical, flexible, convenient, control reliable advantage, make simple, Meteorological is few, failure rate is low, installation and maintenance are easy and convenient, there is good value for applications, utilize the present invention can reduce the consumption of grinding wheel, realize the labour intensity that a key controls to reduce post workman automatically, environmental pollution is little, thus improves and cut ring efficiency.
