Abstract
The utility model relates to a construction clamp, and in particular relates to a construction clamp for turning over a large thin-wall stainless steel component of a nuclear power deaerator. The turnover construction clamp comprises two turnover clamps (1), wherein the two turnover clamps (1) are relatively arranged from top to bottom and are connected through a bolt; and the turnover clamps (1) are provided with lifting lugs (2) and are connected with a hoisting rigging (3) through the lifting lugs (2).The turnover construction clamp disclosed by the utility model has the beneficial effects that the turnover construction clamp is simple to operate, low in cost, convenient to use, safe and reliable, and with the turnover construction clamp, the deformation of the component can be effectively controlled, and the turnover construction clamp is rather suitable to the turnover of a middle thin-wall stainless steel component.
Description
Technical field
The utility model relates to a kind of construction anchor clamps, relates in particular to a kind of construction anchor clamps that nuclear power deaerator large thin-wall parts of stainless steel is overturn.
Background technology
That the deoxygenation unit of nuclear power station oxygen-eliminating device is generally is baroque " in " the type parts, in the process of assembly welding nuclear power deaerator deoxygenation unit, need to repeatedly overturn to parts.And the deoxygenation unit adopts thin-wall stainless steel to make, and volume, larger from weight average, makes easily parts produce very large deformation when using conventional method to carry out above operation.
The utility model content
Technique effect of the present utility model can overcome defects, and a kind of upset construction anchor clamps are provided, and upset is convenient in its effectively control assembly distortion.
For achieving the above object, the utility model adopts following technical scheme: it comprises two turnover fixtures that are oppositely arranged up and down, is bolted between two turnover fixtures up and down, and turnover fixture is provided with hanger, and turnover fixture is connected with hoisting rig by hanger.
The utility model be highly suitable for thin-wall stainless steel " in " upset of type parts, it is simple to operate, cost is low, and is easy to use, safe and reliable, effectively control assembly distortion.
Turnover fixture comprises base plate, side plate, and base plate and side plate are affixed, and hanger is arranged on the base plate, and the end of side plate is provided with the connection gusset, is fixedly connected with by connecting gusset between two turnover fixtures up and down.Each connects the bolt hole that respectively bores 4 φ 20 on the gusset, is convenient to fastening turnover fixture.
At least be provided with two hangers on each base plate.
Described operating platform is laid rubber peel at platform, to prevent parts of stainless steel generation carburizing for the operation platform of the assembly welding deoxygenation unit of the material-pavings such as use steel plate, shaped steel.
The beneficial effects of the utility model are: at first, this method of operation in operation is simple, and cost is low, and is easy to use, safe and reliable; The second, the effectively control assembly distortion of this method of operating, be highly suitable for thin-wall stainless steel " in " upset of type parts.
Description of drawings
Fig. 1 is the utility model arrangement works view;
Fig. 2 is working state schematic representation after the utility model upset;
Fig. 3 is the clamp structure schematic diagram;
Among the figure: 1. turnover fixture; 2. hanger; 3. hoisting rig; 4. base plate; 5. side plate; 6. connection gusset; 7. workpiece to be flipped.
The specific embodiment
As shown in Figure 1 and Figure 2, upset construction anchor clamps of the present utility model comprise two turnover fixtures 1 that are oppositely arranged up and down, are bolted between two turnover fixtures 1 up and down, and turnover fixture 1 is provided with hanger 2, and turnover fixture 1 is connected with hoisting rig 3 by hanger 2.
As shown in Figure 3, turnover fixture 1 comprises base plate 4, side plate 5, and base plate 4 is affixed with side plate 5, and hanger 2 is arranged on the base plate 4, and the end of side plate 5 is provided with and connects gusset 6, is fixedly connected with by connecting gusset 6 between two turnover fixtures 1 up and down.Each base plate 4 is provided with two hangers 2.
Method for turning of the present utility model may further comprise the steps:
The first step, according to drawing requirement processing stainless steel turnover fixture 1, these parts are the stainless-steel sheet group to forming, cross section type be " in " type, comprise base plate 4, side plate 5 and contents.At first contents and base plate are carried out assembly welding, the complete rear butt welded seam of assembly welding permeates detection, and guarantees the figure paper size, after the passed examination group to the parts side plate, and etc. pending reverse welding.
Second step, the processing turnover fixture: two parts all use the I-steel assembly welding to form up and down, and add weldering hanger 2 at four jiaos, grip size by thin-wall stainless steel to be lifted " in " sectional dimension of type parts determines.Two turnover fixtures 1 use bolt to connect the upset frock up and down.
The 3rd step, carry out thin-wall stainless steel " in " type part turnover construction: need two cover turnover fixtures 1 during construction, at first the first half of two cover turnover fixtures 1 is placed on the lifting position of workpiece 7 to be flipped, then by bolt turnover fixture the latter half is fastened on the first half.Subsequently with two cranes pass through hoisting rig 3 hook two the cover turnover fixtures four hangers lift by crane, after the liftoff sufficiently high distance, changing successively the Heave Here of four suspension hooks overturns, namely at first will change on hanger corresponding to diagonal with the rigging that hanger on the first set turnover fixture connects, then changing on hanger corresponding to diagonal with the second rigging that overlaps hanger connection on the turnover fixture, use the same method the residue suspension centre is adjusted, then workpiece 7 to be flipped slowly is placed on the operating platform, takes off at last turnover fixture and finish the upset construction.
The 4th step, according to technological requirement, repeatedly overturn to thin-wall stainless steel " in " the type parts weld.
In the utility model, the hanger 2 that arranges at anchor clamps is not limited to four, also can be other quantity, and hanger 2 quantity are mainly determined according to volume, the weight of parts in the practice of construction process.Described anchor clamps also be not limited to " in " the type parts, can improve according to workpiece 7 to be flipped.
