Abstract
The utility model relates to a pipe flange replacing tool, in particular to a pipe flange replacing and positioning tool. The utility model is characterized in that the pipe flange replacing and fast positioning tool comprises a pair of clamps; the clamps comprise two semicircular ring parts which are combined into a circle; both ends of each semicircular ring part are respectively provided with a side plate, and the side plates are connected by a bolt and nut pair; and a plurality of positioning bolt holes for connecting the bolts and a plurality of thimble hole for arranging thimbles are uniformly arranged along the circumference on the semicircular rings. When the utility model is used, various medium pipe flanges can be fast positioned on the ground by ordinary constructors, and the construction quality can meet the requirements of the construction specifications.
Description
Technical field
The utility model relates to pipe flange and changes instrument, relates in particular to a kind of pipe flange and changes orientation tool.
Background technology
Metallurgical and chemical enterprise has medium pipelines such as the huge cooling water pipeline of quantity, oxygen channel, nitrogen pipeline, gas piping, these medium pipelines are after operation a period of time, adpting flange on the pipeline is owing to reasons such as fatigues, the place that is connected with pipeline cracks through being everlasting, cause pipe-line equipment to produce potential safety hazard, must in time change.Palpus off-line operation when pipe flange is changed, concrete way is: the valve that the flange crackle takes place is removed from pipeline, then two old law orchids are cut down, then new flange and valve body being put into former pipeline position carries out bolted the hole is located, position with being scribed ss to lead so that flange bolt is fastening, construction error is big, time is long, workmen's technical ability is had relatively high expectations, and the requirement of pipeline construction specification technique can not be satisfied in the position of partly ruling, then new flange being carried out spot welding fixes, again remove integral body then and transport to ground and carry out flange welding, welding finishes after flaw detection meets the demands, and transports original position again back and returns dress, very waste time and energy, the flange position error is bigger simultaneously.For installation site height, pipeline that the many sizes of flange bolt quantity are big, in the flange position fixing process, to consume a large amount of time and labour, labour intensity is very big simultaneously.
Summary of the invention
The utility model is intended to solve the above-mentioned defective of prior art, provides a kind of pipe flange to change quick orientation tool.The general workmen of the utility model can both locate on ground fast to all kinds of medium pipeline flanges, and construction quality is all in job specfication requires.
The utility model is achieved in that
A kind of pipe flange is changed quick orientation tool, and it comprises: a pair of jig, and it comprises two semi-round ring shape parts and pieces together a circle that the two ends of each semicircular ring respectively carry a side plate, and are linked together by a bolt and nut pair; Also be provided with positioning bolt hole and some centre holes that thimble is set of some connecting bolts on the described semicircular ring equably along circumference.
Described a kind of pipe flange is changed quick orientation tool, and described positioning bolt hole has eight.
Described a kind of pipe flange is changed quick orientation tool, and described centre hole has four.
Before the utility model flange is changed, process a special fixture, bolt hole is consistent with former flange, when construction, special fixture is enclosed within on the pipeline, with eight bolt jockeies and old law orchid, position the fastening clips bolts at two ends with four jackscrew adjustment distances, after treating that anchor clamps are fixing, remove eight bolts, four jackscrews cut off the old law orchid.Return when adorning new flange,, adjust distance with eight bolt jockey bolts hole and new flange bolt hole, after meeting the demands, the spot welding flange, assurance flange location dimension is in prescribed limit.
Than prior art, this city gushes the novel pipe flange that utilizes changes quick location specific purpose tool to hole, location, only need special fixture is located, flange just has very high positioning accuracy, it is just convenient and swift to return dress, general workmen also is easy to finish, do not need the very workmen of high-tech level, more can be because of workmen's difference, flange return the dress deviation big, this set of tubes flange is changed quick orientation tool and is changed to pipe flange, and a kind of quick, easy and low cost method is provided, and simple to operation.
Description of drawings
Below, further specify the utility model in conjunction with the accompanying drawings:
Fig. 1 is the utility model scheme of installation.
The specific embodiment
As shown in Figure 1, a kind of pipe flange is changed quick orientation tool, and it comprises: a pair of jig, and it comprises two semicircular ring 1 parts and pieces together a circle that the two ends of each semicircular ring 1 respectively carry a side plate 3, and are linked together by a bolt and nut pair 4; Also be provided with eight positioning bolt holes and four centre holes that thimble 6 is set of connecting bolt 5 on the described semicircular ring 1 equably along circumference.
Claims (3)
1. a pipe flange is changed quick orientation tool, it is characterized in that it comprises: a pair of jig, and it comprises two semicircular ring parts and pieces together a circle that the two ends of each semicircular ring respectively carry a side plate, and are linked together by a bolt and nut pair; Also be provided with positioning bolt hole and some centre holes that thimble is set of some connecting bolts on the described semicircular ring equably along circumference.
2. a kind of pipe flange according to claim 1 is changed quick orientation tool, it is characterized in that, described positioning bolt hole has eight.
