The pressure vessel flange is taken over mouthpart
The utility model relates to the pressure vessel manufacturing technology, and specifically a kind of pressure vessel flange is taken over mouthpart.
In the prefabricated process of pressure vessel; It is the basic installation procedure that the erector often runs into that the counterpart of flange and adapter is connected; Though it is simple that this one procedure seems; The quality of counterpart directly has influence on electric welder's welding quality, and it is right that the counterpart mode that we are accustomed to habitually in the past is to use two screwdrivers to organize on the spot.
In the original counterpart method, use two screwdrivers to adjust the counterpart gap, remove the welding rod of coating between the gap beyond the Great Wall; The metal at solder joint place cooling after-contraction after spot welding is accomplished clamps the welding rod of plug at the counterpart gap location, and manpower can't take out it; Have to use sanding machine that welding rod is rubbed; In polishing, inevitably can damage the groove and the root face of weld seam, cause difficulty when giving weld bond; Wasting welding rod besides, after group is to a collection of pipe connecting flange, completely is the welding rod of discarding.
This original counterpart mode; Efficient is very low, and the human factor influence is big, and concentricity is difficult to accurate control; Satisfied not the demand of technical standard that present pressure vessel is made far away; And the mismatch phenomenon often appears in the process of counterpart, if erector and electric welder cooperate the frequent perforating of electro-welding arc meeting when mouthful group is not right fortunately, also have installation personnel face not have safeguard procedures; When if the counterpart workload is big, this day the get off position of face and neck burnt by electro-welding arc through regular meeting, if often work like this of operating personnel can cause very big injury to its health of human body.This original method is the wasting manpower and material resources really, should discard this group of right mode.
In view of this, to the problems referred to above, propose a kind of pressure vessel flange reasonable in design and that effectively improve above-mentioned disappearance and take over mouthpart.
Summary of the invention
The purpose of the utility model is to provide the pressure vessel flange to take over mouthpart, and simple to operate, efficient is high, the concentricity accurate positioning.Can the flange of pressure vessel take over prefabricated group to process in, the group that efficient and standard ground removes to carry out pipe connecting flange to and welding, to adapt to the right needs of pressure vessel flange adapter weld bond group.
In order to reach above-mentioned purpose; The utility model provides the pressure vessel flange to take over mouthpart, comprise workbench and be arranged on the workbench be used for the clamping flange clamping device and be used for making taking over and move up and down so that the spiral lift device of alignment flange interface.
Said spiral lift device bottom is provided with the horizontal location carriage that is used for holding adapter.
The central axis of the central axis of said clamping device and horizontal location carriage overlaps overlooking on the direction.
Said clamping device is a bench vice formula clamping device, and the front end of said clamping device is provided with the perpendicular positioning block.
Said spiral lift device is provided with guide post.
Compared to prior art, all problems that the utility model has run into when well having solved counterpart in the prior art; Clamping device grasps flange (elbow); Adapter is positioned on the horizontal location carriage on spiral lift device top; Adjust concentricity, unfitness of butt joint and the counterpart gap of elbow and welded tube up and down through spiral lift device after, as requested the weld bond point is welded by the electric welder.Solve three problems once: first has solved the problem that old-fashioned counterpart method runs into bad adjustment unfitness of butt joint and counterpart gap; Second has solved the long-time counterpart of installation personnel can't be prone to the welding flash that human body is caused away from the irradiation of electro-welding arc; The 3rd has solved and when counterpart, has not be used between the weld bond problem that welding rod is beyond the Great Wall controlled the counterpart gap, and such engineering is got off and just can be practiced thrift many welding rods and material.Flange is taken over mouthpart, and with high content of technology, practical, simple to operate, counterpart is rapid, accurately, is very easy to construction, and pressure vessel manufacturers is used, and can improve the above effect of several times, and comprehensive benefit very significantly.

The specific embodiment
Detailed description of relevant the utility model and technology contents, conjunction with figs. are explained as follows, yet accompanying drawing only provides the usefulness of reference with explanation, are not to be used for the utility model is limited.
According to Fig. 1, Fig. 2, shown in Figure 3; The pressure vessel flange is taken over mouthpart; Comprise workbench 1 and be arranged on the workbench be used for clamping flange 6 clamping device 4 and be used for making and take over 8 and move up and down so that the spiral lift device 3 of alignment flange interface, spiral lift device is provided with guide post 2.The spiral lift device bottom is provided with the horizontal location carriage 7 that is used for holding adapter.The central axis of the central axis of clamping device 4 and horizontal location carriage 7 overlaps overlooking on the direction.Clamping device is a bench vice formula clamping device, and the front end of said clamping device is provided with perpendicular positioning block 5.
The counterpart method of the utility model: use flange to take over clamping and lowering or hoisting gear to mouthpart; Clamping device grasps flange (elbow); Adapter is positioned on the horizontal location carriage of taking over above the spiral lift device; Adjust concentricity, unfitness of butt joint and the counterpart gap of elbow and welded tube up and down through spiral lift device after, as requested the weld bond point is welded by the electric welder.This flange takes over that mouthpart has been solved problem, the installation personnel in bad adjustment unfitness of butt joint that old-fashioned counterpart method runs into and counterpart gap is long-time. and counterpart will with the hands go holding up during owing to counterpart; And can't be away from the irradiation of electro-welding arc injury to human body; When counterpart, not be used between the weld bond welding rod beyond the Great Wall in addition and control the gap of counterpart, under an engineering, just can practice thrift many welding rods like this.
The above is merely the preferred embodiment of the utility model, and non-in order to limit the claim of the utility model, the equivalence of the patent spirit of other utilization the utility model changes, and all should all belong to the claim of the utility model.
