Description
Technical field
The utility model relates to a kind of for the right equipment of penstock circumferential weld group, relates in particular to a kind of high-strength steel penstock circumferential weld group to quick tooled joint system.
Background technology
The penstock that traditional power station is made by 80 feather weight high-strength steel fall the joint group to the time, because 80 feather weight high-strength steel carbon equivalents are high, crack sensitivity is strong, roundness deviation when steel pipe rolls in addition, must adopt spot welding to press the mode of horse or wedge to be grouping when falling to saving, and because 80 feather weight high-strength steel intensity are high, hardness is large, very difficult when adopting with the upper type tooled joint.Technological requirement when horse or chock are pressed in spot welding is consistent with formal weld seam, must carry out first preheating then could spot welding, again must the range points welding position when removing put the above flame of root 5mm cuts off, afterwards the polishing to and mother metal flush, also to carry out penetrant inspection etc. at last, prevent the Dangerous defects such as crackle, operation is very loaded down with trivial details, and construction labour intensity is large, has a strong impact on the quick production that has limited enterprise.
Summary of the invention
The purpose of this utility model just is to provide in order to address the above problem a kind of high-strength steel penstock circumferential weld group to quick tooled joint system.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises support post, job platform, hydraulic power unit, high-pressure oil pipe, hydraulic jack, rotary bracket, top thick stick and radian plate, described support post passes the centre bore of described job platform, described rotary bracket is installed on the top of described support post, described top thick stick comprises two, be installed on respectively the both sides of described rotary bracket, described hydraulic jack is two, be installed on respectively the outer end of two described top thick sticks, described radian plate is two, be installed on respectively the outer end of the piston rod of two described hydraulic jacks, the oil pipe of two described hydraulic jacks is connected with the oil-out of described hydraulic power unit by high-pressure oil pipe respectively.
During use, two the right single-unit penstocks of joint group that fall to be assembled are hung and upper and lower arrangement outside to the utility model, the utility model integral body places penstock inner.Then start hydraulic power unit, the quick tooled joint adjustment of circumferential weld can be carried out, clock like precision, convenient, fast in the top of the radian plate on the piston rod of hydraulic jack to the circumferential weld between the upper and lower penstock that needs to adjust.
The beneficial effects of the utility model are:
Utilize the utility model to carry out high-strength steel penstock circumferential weld group pair, speed is fast, efficient is high, the tooled joint quality is good; The utility model is simple in structure, can on-the-spot processing and fabricating, can reuse for a long time, and the cost less investment, construction cost is low, is convenient to promote.The utility model thoroughly solved traditional penstock circumferential weld group to 80 feather weight high-strength steel groups especially to the time inefficiency and quality can't basic assurance disadvantage.
Description of drawings
Structural representation when Fig. 1 is the utility model application.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model comprises support post 12, job platform 10, hydraulic power unit 7, high-pressure oil pipe 6, hydraulic jack 3, rotary bracket 1, top thick stick 2 and radian plate 4, support post 12 passes the centre bore of job platform 10, rotary bracket 1 is installed on the top of support post 12, top thick stick 2 comprises two, be installed on respectively the both sides of rotary bracket 1, hydraulic jack 3 is two, be installed on respectively the outer end of two top thick sticks 2, radian plate 4 is two, be installed on respectively the outer end of the piston rod of two hydraulic jacks 3, the oil pipe of two hydraulic jacks 3 is connected with the oil-out of hydraulic power unit 7 by high-pressure oil pipe 6 respectively.
During installation, the lower end of support post 12 and job platform 10 all are installed on the basis 8, the centre bore of job platform 10 is passed in the upper end of support post 12, then in the upper end of support post 12 rotary bracket 1, top thick stick 2, hydraulic jack 3 and radian plate 4 are installed successively, are connected hydraulic jack 3 with high-pressure oil pipe 6 again and get final product with hydraulic power unit 7.
During operation, at first needs being carried out the right steel pipe to be pieced together of circumferential weld group 9 and steel pipe 11 to be pieced together hangs to the utility model outside, steel pipe 9 to be pieced together and steel pipe 11 to be pieced together are presented, lower arrangement, form circumferential weld 5 between steel pipe 9 to be pieced together and the steel pipe to be pieced together 11, operating personnel stand on the job platform 10 hydraulic jack 3 and radian plate 4 alignings need to be carried out on the circumferential weld 5 of tooled joint, start hydraulic power unit 7, hydraulic oil is by the piston rod of high-pressure oil pipe 6 pusher hydraulic cylinders 3, radian plate 4 tops are changed to being close to circumferential weld 5 and making it produce radian, until steel pipe 9 to be pieced together is consistent with the radian at steel pipe to be pieced together 11 edges, can carries out the spot welding of circumferential weld 5 and fix.Then rotating top thick stick 2 rotary hydraulic cylinders 3 need to carry out circumferential weld 5 places that radian proofreaies and correct and repeat above-mentioned steps can to carry out quick group of circumferential weld 5 right to next place.
