[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] Example 1

[0025] like Figure 1 As shown, the maintenance frame for a tubular heat exchanger provided by the utility model comprises a base plate 4 and a roller 5 installed on the bottom surface of the base plate 4, and also comprises a rotating assembly 2 and a supporting assembly 3 arranged on the base plate. Figure 1 2 shows a state where the tubular heat exchanger body 1 is mounted on a frame.

[0026] like Figures 1 to 5 As shown, the rotating assembly 2 includes an L-shaped support rod 22 arranged above the bottom plate 4 and two arc-shaped support plates 210 arranged on the top of the bottom plate. A T-shaped support plate 23 is inserted into the guide groove 212 opened on the crossbar section of the L-shaped support rod 22. The T-shaped support plate 23 and the L-shaped support rod 22 are vertically slidably connected. Two U-shaped brackets 25 are symmetrically fixedly connected to the bottom surface of the T-shaped support plate 23. A conveying roller 28 is installed inside each U-shaped bracket 25. The surfaces of the two conveying rollers 28 are coaxially sleeved with an annular rubber belt 27. A driving shaft 26 is installed on the surface of one of the U-shaped brackets 25. The driving shaft is fixedly connected to one of the conveying rollers 28. When the driving shaft 26 is connected to the driving mechanism, the conveying roller 28 can be driven to rotate.

[0027] Both ends of the conveying roller 28 pass through the U-shaped bracket 25 , and the conveying roller 28 and the U-shaped bracket 25 are rotatably connected. A positioning block 213 is provided above the L-shaped support rod 22 , and the positioning block 213 and the T-shaped support plate 23 are fixedly connected.

[0028] In this embodiment: the main body 1 of the tubular heat exchanger is supported on two arc-shaped support plates 210. At this time, the surface of the main body 1 of the tubular heat exchanger and the surface of the roller 211 are in contact with each other, and the T-shaped limit plate 21 is inserted into the inside of the T-shaped slide groove 24. After the L-shaped support rod 22 moves to a suitable position, the force applied to the T-shaped support plate 23 is released so that the rubber belt 27 and the surface of the main body 1 of the tubular heat exchanger are in contact with each other. When the main body 1 of the tubular heat exchanger needs to be turned over during the maintenance process, the driving shaft drives the rubber belt 27 to rotate. The rotation of the rubber belt 27 can drive the main body 1 of the tubular heat exchanger to rotate, so that the main body 1 of the tubular heat exchanger rotates. The transmission of the rubber belt 27 can better protect the main body 1 of the tubular heat exchanger. In actual application, a motor that drives the driving shaft to rotate can be installed on the T-shaped limit plate 21, and the motor can also increase the pressure applied by the rubber belt 27 on the main body 1 of the tubular heat exchanger.

[0029] It should be noted that the rubber belt 27 is made of rubber material. The rubber belt 27 fits the surface of the tubular heat exchanger body 1 to drive the tubular heat exchanger body 1 to rotate, avoiding damage to the surface of the tubular heat exchanger body 1. The setting of the positioning block 213 limits the movement range of the T-shaped support plate 23.

[0030] Furthermore, in an optional embodiment, a plurality of rollers 211 are equidistantly arranged in the arc groove 29 formed on the inner arc surface of the arc support plate 210, the rollers 211 are rotatably connected to the arc support plate 210, and the rollers 211 are in contact with the surface of the tubular heat exchanger body 1.

[0031] In this embodiment: the surfaces of the tubular heat exchanger body 1 and the roller 211 are in contact with each other, thereby assisting the rotation of the tubular heat exchanger body 1 and reducing the generation of friction during the rotation of the tubular heat exchanger body 1. The equidistant arrangement of multiple rollers 211 can be suitable for the rotation of tubular heat exchanger bodies 1 with different diameters.

[0032] Furthermore, in an optional embodiment, a T-shaped groove 24 is provided on the top surface of the base plate 4, and a T-shaped limit plate 21 is fixedly connected to the bottom surface of the vertical rod section of the L-shaped support rod 22, and the T-shaped limit plate 21 is inserted into the inside of the T-shaped groove 24, and the T-shaped limit plate 21 and the base plate 4 are connected by transverse sliding.

[0033] In this embodiment, after the maintenance of the tubular heat exchanger body 1 is completed, a force is applied to the L-shaped support rod 22 to make the T-shaped limit plate 21 slide out from the inside of the T-shaped slide groove 24, so that the rubber belt 27 is removed from above the tubular heat exchanger body 1.

[0034] Furthermore, in an optional embodiment, the maintenance frame for the tubular heat exchanger provided by the utility model further includes a support assembly 3 arranged on the surface of the bottom plate 4.

[0035] The support assembly 3 includes a rectangular sleeve 31 fixedly connected to the bottom surface of the arc-shaped support plate 210 and a rectangular placement box 32 inserted into the rectangular sleeve 31. A hydraulic push rod 34 is installed in a built-in groove 33 opened inside the rectangular placement box 32. The rectangular sleeve 31 and the rectangular placement box 32 are vertically slidably connected.

[0036] In this embodiment: the operation of the hydraulic push rod 34 drives the rectangular sleeve 31 to slide along the surface of the rectangular placement box 32 to achieve adjustment of the height of the tubular heat exchanger body 1. The rectangular sleeve 31 fits and slides on the surface of the rectangular placement box 32 to ensure the stability of the tubular heat exchanger body 1 during the height adjustment process. During the height adjustment process of the tubular heat exchanger body 1, the rectangular sleeve 31 fits and slides on the surface of the rectangular placement box 32 to ensure the stability of the tubular heat exchanger body 1 during the height adjustment process.

[0037] Working principle: When inspecting the tubular heat exchanger body 1, place the tubular heat exchanger body 1 inside the two arc-shaped support plates 210. At this time, the surface of the tubular heat exchanger body 1 and the roller 211 fit together, so that the T-shaped limit plate 21 is inserted into the inside of the T-shaped slide groove 24. After the L-shaped support rod 22 moves to a suitable position, release the force applied to the T-shaped support plate 23 so that the rubber belt 27 and the surface of the tubular heat exchanger body 1 fit together, so that the required static friction can be generated between the rubber belt 27 and the tubular heat exchanger body 1. In specific applications, a horizontally penetrating positioning hole can be opened in the vertical section of the T-shaped support plate 23, and a blocking rod can be inserted into the positioning hole to prevent the T-shaped support plate 23 from moving upward relative to the L-shaped support rod 22. When the tubular heat exchanger body 1 needs to be turned over during the maintenance process, the operation of the drive shaft 26 drives the rubber belt 27 to rotate, and the rotation of the rubber belt 27 can drive the tubular heat exchanger body 1 to rotate. The transmission of the rubber belt 27 can better protect the tubular heat exchanger body 1. When the tubular heat exchanger body 1 is overhauled, applying force to the L-shaped support rod 22 can make the T-shaped limit plate 21 slide out from the inside of the T-shaped slide groove 24, so that the rubber belt 27 moves out from the surface of the tubular heat exchanger body 1. The operation of the hydraulic push rod 34 drives the rectangular sleeve 31 to slide along the surface of the rectangular placement box 32 to adjust the height of the tubular heat exchanger body 1. In the process of adjusting the height of the tubular heat exchanger body 1, the rectangular sleeve 31 slides along the surface of the rectangular placement box 32 to ensure the stability of the tubular heat exchanger body 1 during the height adjustment process.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
