Abstract
Description
Technical Field
[0001] The utility model relates to the field of pipeline expansion devices, in particular to a pipeline pulling, inspection and fixing device for a thermal power plant. Background Art
[0002] Boilers are the main equipment components of thermal power plants, and the anti-wear inspection of the boiler's "four tubes", namely the boiler water-cooled wall, superheater, reheater and economizer, is a top priority maintenance project. According to historical data statistics, the number of unplanned shutdowns caused by boiler heating surface leakage accidents accounts for about 40% of the total unplanned shutdowns of the unit, and the unplanned shutdowns caused by boiler four-tube leakage accidents account for about 60% of the total unplanned shutdowns of the boiler. It can be seen that the anti-wear and explosion inspection technology of the boiler four-tube is particularly important.
[0003] For example, when the boiler is shut down for maintenance, it is necessary to pull the low-temperature superheater on the rear heating surface of the boiler for inspection. During the inspection, because the original tube row gap is 100mm, it is necessary to pull the spacing to 700mm-800mm before the anti-wear inspectors can enter for inspection. The existing pulling inspection device generally uses square wood to connect the holes to fix the tube row. After multiple pulling inspections, it is found that the operation of using square wood to connect the holes to fix the tube row after the tube row is pulled is cumbersome, and once the square wood tilts, the spacing between the tube rows will be reduced instantly, and the inspectors may suffer a personal mechanical squeeze accident, which poses a great personal safety hazard.
[0004] Therefore, there is an urgent need for a pipeline pulling and inspection fixing device for a thermal power plant, which is simple to operate and highly safe. Utility Model Content

The fixing frame is arranged at the lower part of the two support rods 100, and there are two buckles 200, which are arranged at both ends of the fixing frame respectively.
[0030] In actual operation, the buckle 200 can be tied to the pipe row by wire or hemp rope.
[0031] like Figure 2 As shown, Figure 2 Figure (a) is a left view of an embodiment of the utility model, Figure 2 FIG. (b) is a right view of an embodiment of the utility model. The fixing frame comprises a first frame, a second frame and a reinforcing tie rod 600; the first frame and the second frame are connected by the reinforcing tie rod 600.
[0032] The first frame includes a first support beam 301, a second support beam 302 and two support frames 400; the first support beam 301 and the second support beam 302 are arranged in parallel; the two ends of the first support beam 301 and the second support beam 302 are welded with the support frames 400 to form a rectangular support frame.
[0033] The second frame includes a third support beam 303, a fourth support beam 304 and two support frames 400; the third support beam 303 and the fourth support beam 304 are arranged in parallel; the two ends of the third support beam 303 and the fourth support beam 304 are respectively welded with the support frames 400 to form a rectangular support frame.
[0034] The position of the first frame corresponds to the position of the second frame; the first frame is welded to the bottom of the first support rod 101, the second frame is welded to the bottom of the second support rod 102, and the support frame 400 is parallel to the first support rod 101 or the second support rod 102.
[0035] The reinforcing bars 600 are welded between the upper, middle and lower parts of the first support beam 301 and the third support beam 303 , respectively; the reinforcing bars 400 are welded between the upper, middle and lower parts of the second support beam 302 and the fourth support beam 304 , respectively.
[0036] The fixing frame further includes a supporting crossbeam, and the supporting crossbeam includes a first crossbeam 501 and a second crossbeam 502; one end of the first crossbeam 501 is welded to the reinforcing tie bar 600 in the middle of the first supporting beam 301 and the third supporting beam 303, and the other end is welded to the reinforcing tie bar 600 in the middle of the second supporting beam 302 and the fourth supporting beam 304;
