Detailed Description
In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.
As shown in fig. 1-3, the present invention comprises an upper fixing mechanism and a lower fixing mechanism. Lower fixed establishment is equipped with one set of coupling assembling respectively at base 1's both ends including base 1 that has body standing groove 2, and every set of coupling assembling all includes two screw rods 3, and two screw rods 3 articulate respectively in base 1's both sides.
Go up fixed establishment includes two fixing bases 4, every fixing base 4 corresponds a set of coupling assembling. All be equipped with body spacing groove 5 on every fixing base 4, the notch of body spacing groove 5 and the relative setting of notch of body standing groove 2. Two connecting plates 6 are fixedly connected to each fixing seat 4, the two connecting plates 6 are located on two sides of each fixing seat 4 respectively, a through hole 7 is formed in each connecting plate 6, and the two screw rods 3 of one set of connecting assembly correspondingly penetrate through the two through holes 7 respectively. A lower limiting nut 9 and an upper fixing nut 8 are connected to each screw rod 3, and the lower limiting nut 9 and the upper fixing nut 8 are respectively positioned on the upper side and the lower side of the connecting plate 6.
In this embodiment, in order to prolong the service life and ensure sufficient fixing strength, the base 1 and the two fixing seats 4 are both made of stainless steel.
In this embodiment, to ensure that the two sides are compressed uniformly, the two sets of connecting assemblies are arranged in mirror image along the axis of the base 1.
During the specific use, be connected one of them fixing base 4 and a set of coupling assembling earlier, the connected mode is for installing spacing nut 9 down on every screw rod 3 earlier, rotates two screw rods 3 and makes two screw rods 3 stand, overlaps fixing base 4 on two screw rods 3, installs fixation nut 8 on every screw rod 3 and realizes fixing of fixing base 4. The other fixing seat 4 is installed in the same manner as above. Two soot blowing pipes needing butt welding are placed in the pipe body placing groove 2, one fixing seat 4 is used for compressing one soot blowing pipe, and the positions of the lower limiting nut 9 and the upper fixing nut 8 are adjusted to adapt to the diameter of the soot blowing pipe so as to press and fix the soot blowing pipe. And after the welding is finished, removing the upper fixing nut 8, removing the fixing seat 4, and finally removing the welded soot blowing pipe from the pipe body placing groove 2.
The accurate spacing of two butt joint soot blowers is realized through the cooperation of last fixed establishment and lower fixed establishment and is fixed, and fixed effectual, the welding process body can not the displacement, has ensured the accuracy of two soot blowers and has effectively aligned, convenient operation, and welding quality has also obtained the assurance.
