However, the four major pipelines under maintenance in the power plant are relatively thick and the insulation is thicker. In order to meet the requirements of metal supervision, the welds need to be inspected. The weld inspection requires the removal of insulation and scaffolding. Because it is a partial demolition, especially the inspection of the welds in the lower or middle part of the vertical pipeline, after the demolition, because there is no support at the bottom, the insulation cotton and outer protection above will fall down, causing the entire pipeline insulation to be disconnected, and recovery is quite difficult. More scaffolding needs to be set up, or even all scaffolding needs to be removed. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1-3 The illustrated large pipe insulation removal and anti-falling tool comprises a pipe body 1 and an insulation layer 2 installed on the circular outer wall of the pipe body 1. When the pipe body 1 is conveying liquid or gas, the insulation layer 2 is used to insulate the pipe body 1 to prevent the external high temperature from entering the pipe body 1, and to prevent the temperature inside the pipe body 1 from spreading outward when conveying high-temperature objects.

[0025] A fastening ring 4 is provided on the lower side of the pipe body 1, and an outer ring 5 is provided on the outer wall of the fastening ring 4 so as to be clamped on the lower side of the pipe body 1 through the fastening ring 4. A plurality of support blocks 3 are fixedly connected at equal intervals on the circular outer wall of the outer ring 5 to limit the position of the thermal insulation layer 2. After the pipe body 1 is cut, the fastening ring 4 and the outer ring 5 can be fixed on the lower side of the pipe body 1, and the position of the thermal insulation layer 2 can be limited by the plurality of support blocks 3 around it to prevent the thermal insulation layer 2 from sliding downward.

[0026] like Figure 2 and Figure 3 As shown, a support plate 6 is fixedly connected to the lowermost side of the circular inner wall of the outer ring 5, a plurality of connecting balls 7 are equidistantly arranged between the outer ring 5 and the fastening ring 4, a spring 8 is fixedly connected between the outer ring 5, the fastening ring 4 and the connecting balls 7, and the plurality of support blocks 3 are all triangular in shape.

[0027] The position of the fastening ring 4 is limited by the support plate 6, so that the fastening ring 4 is in the lateral adjustment direction when adjusting the diameter, to avoid the situation that it falls and cannot contact the inner wall of the pipe body 1. When the fastening ring 4 adjusts its own size, it will pull the spring 8, and after the circular outer wall of the fastening ring 4 fits the inner wall of the pipe body 1, the rebound force provided by the spring 8 clamps the fastening ring 4 and the outer ring 5 on the pipe body 1.

[0028] like Figure 2As shown, the fastening ring 4 includes a telescopic sleeve 9 and a telescopic rod 10 . The telescopic sleeve 9 is arranged on the inner side of the outer ring 5 . The telescopic rod 10 is arranged between the multiple telescopic sleeves 9 . The telescopic rod 10 can slide inside the telescopic sleeve 9 .

[0029] When the diameter of the fastening ring 4 is adjusted, the telescopic sleeve 9 is pressed down so that the telescopic rod 10 is inserted into the inside of the telescopic sleeve 9, and the length of the diameter of the fastening ring 4 is controlled according to the insertion distance.

[0030] like Figure 2 and Figure 3 As shown, a plurality of support blocks 3 are respectively arranged at the four corners of the outer ring 5, and the fastening ring 4 is of an inner telescopic type.

[0031] The support blocks 3 arranged at the four corners of the outer ring 5 can stably lift the falling insulation layer 2 to prevent the insulation layer 2 from sliding down.

[0032] like Figure 4 As shown, the lower end outer walls of the multiple support blocks 3 are fixedly connected with a sliding sleeve 11, and the interior of the multiple sliding sleeves 11 is provided with a sliding rod 14 to increase the supporting area of ​​the support block 3 after being pulled out, and the other ends of the multiple support blocks 3 are fixedly connected with a fixing rod 17, and the interior of the multiple sliding sleeves 11 is provided with a sliding groove 15 to limit the position of the sliding rod 14.

[0033] When the support block 3 cannot support the insulation layer 2 which is currently longer than the support block 3 , the slide rod 14 can be pulled out from the slide sleeve 11 , and the pulled out slide rod 14 and the fixed rod 17 can assist in supporting the insulation layer 2 .

[0034] like Figure 4 As shown, the left end outer walls of the multiple sliding rods 14 are fixedly connected to the baffle 12, the right end outer walls of the multiple baffles 12 are fixedly connected to the magnetic block a13, and the rightmost sides between the upper and lower end inner walls of the multiple sliding grooves 15 are fixedly connected to the magnetic block b16, and the magnetic block a13 and the magnetic block b16 are magnetically adsorbed to each other.

[0035] After the slide bar 14 is pulled out, the baffle 12 will be synchronously driven to move rightward. At this time, the magnetic block a13 and the magnetic block b16 are magnetically attracted to each other to limit the position of the slide bar 14 .

[0036] The implementation principle of this embodiment is: when the pipeline body 1 is transporting liquid or gas, the pipeline body 1 is insulated by the insulation layer 2 to prevent the external high temperature from entering the pipeline body 1, and at the same time prevent the temperature inside the pipeline body 1 from diffusing outward when transporting high-temperature objects. After the pipeline body 1 is cut, the fastening ring 4 and the outer ring 5 can be fixed on the lower side of the pipeline body 1, and the position of the insulation layer 2 can be limited by multiple support blocks 3 around it to prevent the insulation layer 2 from sliding downward.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
