Specific embodiments

[0035] As shown in the figure, the utility model includes a base frame 6, a fixed vertical frame 1 is arranged on one side of the base frame 6, and a movable vertical frame 8 is arranged on one side of the base frame 6; a first horizontal support rod 2 is arranged on the fixed vertical frame 1, and a second horizontal support rod 10 corresponding to the first horizontal support rod 2 is arranged on the movable vertical frame 8; one end of the support chain 7 is detachably connected to the first horizontal support rod 2, and the other end of the support chain 7 is detachably connected to the second horizontal support rod 10.

[0036] The lower ends of the fixed vertical frame 1 and the movable vertical frame 8 are connected to the base frame 6 through vertical frame pin shafts and vertical frame pin holes 15.

[0037] Vertical limiting grooves 14 are arranged at the lower parts of the fixed vertical frame 1 and the movable vertical frame 8, and vertical limiting ports 9 corresponding to the vertical limiting grooves 14 are arranged on the base frame 6; vertical limiting blocks pass through the vertical limiting ports 9 and are inserted into the vertical limiting grooves 14.

[0038] The device of the utility model is used for the heat treatment after the welding of the weld 20, that is, after the welding is completed, the device of the utility model is used for auxiliary heating. For the outermost weld 20, sometimes a roller rack 32 does not need to be arranged on the outside of the outermost weld 20. In this case, the two side vertical frames can be erected through the vertical limiting port 9, the vertical limiting groove 14 and the vertical limiting block, and then the device of the utility model is pushed from the end of the welded pipe body to the outermost weld 20, and then the vertical limiting block is pulled out so that the two side vertical frames are placed on the heating sheet 29.

[0039] The base frame 6 is made of channel steel. The base frame 6 made of channel steel is simple and practical, and is light and easy to move and place.

[0040] A plurality of adjusting limiting plates 21 are evenly distributed along the length direction of the base frame 6 on the base frame 6, and vertical frame pin holes 15 are arranged at the lower parts of the adjusting limiting plates 21. By arranging a plurality of adjusting limiting plates 21, the position of the movable vertical frame 8 can be adjusted according to different diameters of the tank body 30. According to the required width between the fixed vertical frame 1 and the movable vertical frame 8, the connection position at the lower end of the movable vertical frame 8 is selected, the lower end of the movable vertical frame 8 is connected to the adjusting limiting plate 21 at this position, and the vertical frame pin shaft passes through the vertical frame pin hole 15 of the adjusting limiting plate 21 at this position and the vertical frame pin hole 15 at the lower end of the movable vertical frame 8.

[0041] During use, the distance between the bottoms of the fixed vertical frame 1 and the movable vertical frame 8 is slightly larger than the outer diameter of the heating sheet 29 on the outer side of the tank body. When placing, the vertical frames are inclined against the outer wall of the heating sheet 29, as Figure 10 shown.

[0042] When performing local heat treatment on the weld seam 20 of the tank body 30, multiple roller stands 32 are used to support the tank body 30. The multiple roller stands 32 are arranged along the length direction of the tank body 30. The heating sheet 29 and the base frame 6 are placed between adjacent roller stands 32. The lower end of the vertical frame is connected to the base frame 6 through the vertical frame pin shaft and the vertical frame pin hole 15. The vertical frame is inclined and placed on the outer wall of the heating sheet 29 (a protective pad can also be provided on the outer wall of the heating sheet 29, and the vertical frame is inclined and placed on the outer wall of the protective pad), which is naturally stable.

[0043] The pin shaft connection position between the lower end of the fixed vertical frame 1 and the base frame 6 is higher than the pin shaft connection position between the lower end of the movable vertical frame 8 and the base frame 6.

[0044] The base frame 6 is a rectangular ring structure. Vertical frame pin holes 15 are correspondingly provided on the inner vertical side 13 and the outer vertical side 12 of the rectangular ring. A placement groove 18 is provided on the inner vertical side 13 corresponding to the second transverse support rod 10.

[0045] When the device is folded and retracted, the movable vertical frame 8 can be first laid down towards the base frame 6. The second transverse support rod 10 enters the placement groove 18, and the movable vertical frame 8 is laid flat. Then the fixed vertical frame 1 is laid down towards the base frame 6. Since the pin shaft connection position between the lower end of the fixed vertical frame 1 and the base frame 6 is higher than the pin shaft connection position between the lower end of the movable vertical frame 8 and the base frame 6, the fixed vertical frame 1 can be laid flat on the upper end of the movable vertical frame 8, which is convenient for the device to be laid flat and occupies a small space.

[0046] The support chain 7 is made of iron chain.

[0047] The cross-section of the first transverse support rod 2 is circular; one end of the first transverse support rod 2 passes through one side frame of the fixed vertical frame 1, and the other end of the first transverse support rod 2 passes through the other side frame of the fixed vertical frame 1 and is connected with a ratchet wheel 4. A ratchet wheel top block 3 is correspondingly provided on the fixed vertical frame 1 above the ratchet wheel 4. The ratchet wheel top block 3 is connected to the fixed vertical frame 1 through a shaft. A connecting block 16 is provided on the fixed vertical frame 1 above the ratchet wheel top block 3. A ratchet wheel top block limiting elastic piece 17 is connected to the connecting block 16 through a fastening screw.

[0048] The ratchet wheel top block limiting elastic piece 17 is made of a metal sheet. The ratchet wheel top block limiting elastic piece 17 is used to prevent the large-scale rotation of the ratchet wheel top block 3, prevent the ratchet wheel top block 3 from rotating more than 180 degrees, and lose the function of the ratchet wheel top block 3. The ratchet wheel top block limiting elastic piece 17 does not limit the small-scale rotation of the ratchet wheel top block 3.

[0049] There are multiple support chains 7, which are arranged side by side between the first transverse support rod 2 and the second transverse support rod 10. According to the width of the heating area, several more support chains 7 can be installed.

[0050] Both ends of the support chain 7 are respectively connected to the first transverse support rod 2 and the second transverse support rod 10 through hooks 11.

[0051] The first horizontal support rod 2 and the second horizontal support rod 10 are connected to the support chain 7 through the support chain connection pin 28 and the support chain connection pin hole. A plurality of support chain connection pin holes are correspondingly arranged on the first horizontal support rod 2 and the second horizontal support rod 10 for installing a plurality of support chains 7, which are fixed with the support chain connection pin 28.

[0052] There are a plurality of the first horizontal support rods 2 and the second horizontal support rods 10, which are evenly distributed vertically. By setting a plurality of horizontal support rods, the support chain 7 can be connected at a suitable height according to needs.

[0053] The ratchet 4 and the ratchet top block 3 are used to naturally lock the support chain 7 in a tightened state, and it cannot reverse.

[0054] During the heat treatment process, the heating sheet 29 may grow due to temperature and gravity. The tightness of the support chain 7 can be adjusted at any time (a jacking hole 19 can be provided at the end of the first horizontal support rod 2, and the direction of the jacking hole 19 is perpendicular to the length direction of the first horizontal support rod 2. When it is necessary to rotate the first horizontal support rod 2, the inserting rod can be inserted into the jacking hole 19 and the inserting rod can be pulled to rotate the first horizontal support rod 2), so as to keep the heating sheet 29 in close contact with the tank body at all times.

[0055] Universal wheels 22 are provided at the lower end of the base frame 6. By setting the universal wheels 22 on the base frame 6, it is convenient to move the device.

[0056] The universal wheels 22 are connected to the base frame 6 through the universal wheel supports 5. A wheel axle sleeve 25 is provided on the universal wheel support 5, and a U-shaped height adjustment groove 26 is provided on the wall of the wheel axle sleeve 25; a horizontal height adjustment pin 23 is provided on the connecting rod 24 of the universal wheel 22 corresponding to the U-shaped height adjustment groove 26.

[0057] By providing the U-shaped height adjustment groove 26 on the wheel axle sleeve 25 and cooperating with the height adjustment pin 23 on the connecting rod 24 of the universal wheel 22, the height of the universal wheel 22 can be adjusted. During application, the height adjustment pin 23 is screwed out (that is, the height adjustment pin 23 is rotated from the short vertical strip groove of the U-shaped height adjustment groove 26 to the long vertical strip groove), the universal wheel 22 does not bear force, the lower end of the base frame 6 directly contacts the ground, the base frame 6 is stable, and the universal wheel 22 is protected.

[0058] When in use, the heat treatment auxiliary device of the present invention can be set in two ways:

[0059] The first way: The fixed vertical frame 1 and the movable vertical frame 8 can be separated from the base frame 6 first, the base frame 6 is moved under the tank body 30, and then the fixed vertical frame 1 and the movable vertical frame 8 are connected to the base frame 6 through the vertical frame pin and the vertical frame pin hole 15, and the fixed vertical frame 1 and the movable vertical frame 8 lean against the outer wall of the heating sheet 29.

[0060] The second method: Rotate the fixed vertical frame 1 and the movable vertical frame 8 outward around their respective vertical frame pins and lay them down. Then move the device under the tank body 30, and then rotate the fixed vertical frame 1 and the movable vertical frame 8 upright around their respective vertical frame pins and turn them inward to rest on the outer wall of the heating sheet 29.

[0061] Connect the support chain 7 between the two side vertical frames, rotate the first horizontal support rod 2, tighten the support chain 7, and hold the heating sheet 29 tightly so that the heating sheet 29 is close to the tank body for heating.

[0062] After completion, loosen the fastening screws on the connecting block 16. The ratchet top block limiting elastic piece 17 no longer limits the position of the ratchet top block 3. Lift the ratchet top block 3 and rotate the first horizontal support rod 2 in the reverse direction to separate the support chain 7 from the heating sheet 29. Pull out the support chain connecting pin 28 to separate the support chain 7 from the first horizontal support rod 2 and the second horizontal support rod 10. Lay down the fixed vertical frame 1 and the movable vertical frame 8 outward and withdraw the device from under the tank body 30.
