Description
Technical field
The invention belongs to the technical field of metal solder, being specifically related to a kind of for adjusting the instrument of weld bond group to unfitness of butt joint.
Background technology
Weld bond group is to one of the important process content being nuclear island of nuclear power station Pipe installing; a lot of pipeline is seamed steel pipe at the construction field (site); mouth of pipe circularity can not show a candle to seamless steel pipe; also have near the section of tubing mouth of pipe and be welded with backplate when prefabricated; because welding deformation usually causes mouth of pipe circularity to reduce; so often there will be pipeline misalignment during pipe string, and the size of the unfitness of butt joint of pipe string directly affects complexity and the qualification rate of welding.Welding bead detection ruler to be used during pipe string to measure weld bond group right unfitness of butt joint, if unfitness of butt joint is excessive, exceeded the scope that welding requirements specifies, just need to adjust the right unfitness of butt joint of weld bond group, to make unfitness of butt joint within the limits prescribed.The patent No. be CN201410406964.6 application discloses a kind of instrument adjusting unfitness of butt joint, this instrument comprises jack, jack supports, arm-tie, arm-tie pin and drag hook, the operation principle of jack is used to produce pressure to adjust unfitness of butt joint to pipeline, but this tool construction is more complicated, require enough spaces during use to work to enable jack, and the construction environment at scene is very complicated, the environment of some construction is narrower and small, and jack cannot be used to adjust the right unfitness of butt joint of weld bond group.
Summary of the invention
In order to the tool construction solving existing adjustment unfitness of butt joint is complicated, operating space requires large problem, the present invention proposes a kind of for adjusting the instrument of weld bond group to unfitness of butt joint, and this tool construction is simple, can adjust unfitness of butt joint in narrow and small construction environment.
Of the present inventionly comprise fixed body and voussoir for adjusting the instrument of weld bond group to unfitness of butt joint; Described fixed body comprises horizontal block and vertical blocks, and described vertical blocks is vertical with horizontal block is connected to form L-type structure; Described voussoir is the structure of wedge shape; When using described instrument, the free end of described vertical blocks is fixed on the lower pipeline in position, and makes horizontal block be positioned at the top of the higher pipeline in position, described voussoir is stuck between the higher pipeline of described horizontal block and position.
Wherein, described fixed body is provided with handle.The effect of handle is that handled easily personnel take fixed body.
Wherein, described fixed body and voussoir are respectively equipped with connector.When using instrument of the present invention, rope is through at respectively in the connector of fixed body and voussoir, to be connected with fixed body by voussoir, prevents voussoir from use falling, add the security of instrument of the present invention.
Wherein, described connector is circular ring.
Wherein, the free end of the vertical blocks of described fixed body is the arc with described tube fit.Such one side fixed body can be more firm be fixed on pipeline; If the free end of fixed body is plane on the other hand, instrument of the present invention can be fixed on the larger pipeline of diameter easily, but be inconvenient to be fixed on above the less pipeline of diameter, and the free end of vertical blocks is set to the arc with tube fit, can easily the fixed body of instrument of the present invention be fixed on the less pipeline of diameter like this.
Of the present invention for adjusting the beneficial effect of weld bond group to the instrument of unfitness of butt joint: when using instrument of the present invention, by beaing voussoir with iron hammer, the pipeline that voussoir is higher to position produces downward pressure, thus the unfitness of butt joint that the weld bond group reducing two pipelines is right, reach the object of the right unfitness of butt joint of adjustment weld bond group.Tool operation of the present invention is simple, and easy left-hand seat is easy to use, and operating personnel use instrument of the present invention to adjust the right unfitness of butt joint of weld bond group, and the time expended is few, improves operating efficiency.Tool construction of the present invention is simple, and compact is easy to carry, can apply in a flexible way at the construction field (site), can be applied to the construction environment of narrow space.Instrument of the present invention uses the existing metal material in job site just can make, and cost of manufacture is lower, makes construction cost be in controlled state.

Detailed description of the invention
Instrument of the present invention is introduced below in conjunction with Fig. 1-Fig. 4.
Of the present inventionly comprise fixed body 10 and voussoir 13 for adjusting the instrument of weld bond group to unfitness of butt joint.As shown in Figure 1, fixed body 10 comprises horizontal block 101 and vertical blocks 102, and vertical blocks 102 is vertically connected with horizontal block 101, and vertical blocks 102 and horizontal block 101 form L-type structure; Fixed body 10 is provided with handle 12, fixed body 10 is also provided with connector 11, this connector 11 is circular ring, and connector 11 can be welded on fixed body 10.As shown in Figure 2, voussoir 13 is the structure of wedge shape, and the bottom surface of voussoir 13 is provided with connector 11, and this connector 11 is circular ring, can be welded on voussoir 11.
As shown in Figure 3, the using method of instrument of the present invention: the first step, uses welding bead detection ruler to measure the right unfitness of butt joint of weld bond group, finds out the lower pipeline in position 14; Second step, the free end of the vertical blocks 102 of the fixed body 10 of instrument of the present invention is fixed on the lower pipeline in position 14, namely be fixed on the joint edge that position is lower, and make the horizontal block 101 of fixed body 10 be positioned at the top of the higher pipeline in position 14, wherein, vertical blocks 102 can be that point is welded on pipeline 14; 3rd step, is stuck in voussoir 13 between the higher pipeline 14 of the horizontal block 101 of fixed body 10 and position, beats voussoir 13 with iron hammer, and the higher pipeline 14 in voussoir 13 pairs of positions produces downward pressure, thus the unfitness of butt joint that the weld bond group reducing two pipelines 14 is right; 4th step, uses welding bead detection ruler to measure the right unfitness of butt joint of weld bond group, if the right unfitness of butt joint of weld bond group is still greater than the scope of welding requirements, then uses instrument of the present invention to continue adjustment unfitness of butt joint, until unfitness of butt joint is in the scope of welding requirements.
Wherein, the effect of handle 12 is that handled easily personnel take fixed body 10.
Wherein, when using instrument of the present invention, rope is through at respectively in the connector 11 of fixed body 10 and voussoir 13, so that voussoir 13 is connected with fixed body 10, prevents voussoir 13 from use falling, add the security of instrument of the present invention.
As shown in Figure 4, vertical blocks 102 free end of the fixed body 10 of instrument of the present invention is the arc coordinated with pipeline 14, and what fixed body 10 can be more firm so on the one hand is fixed on pipeline 14; If the free end of fixed body 10 is plane on the other hand, instrument of the present invention can be fixed on the larger pipeline of diameter easily, but be inconvenient to be fixed on above the less pipeline of diameter, and the free end of vertical blocks 102 is set to the arc that coordinates with pipeline 14, can easily the fixed body 10 of instrument of the present invention be fixed on the less pipeline of diameter like this.
