[0034] In some optional embodiments, as shown in Figure 1 and Figure 9 The lifting type rolling support unit includes a bottom plate 53 arranged below the base 1. The bottom of the bottom plate 53 is fixedly connected with a plurality of rollers 54. A plurality of hydraulic telescopic rods 55 are fixedly connected to the bottom plate 53.

The mounting box 67 and the box cover 15 are fixedly connected through a plurality of third bolts 65. The electric heating tape feeding structure includes a mounting shaft 59 arranged in the mounting box 67. The mounting shaft 59 penetrates through the box cover 15. A bearing is arranged at the connection position of the mounting shaft 59 and the box cover 15. A first damping disc 60 is fixedly connected to the mounting shaft 59. A second damping disc 63 is arranged on the side of the first damping disc 60 away from the box cover 15. The second damping disc 63 is in contact with the first damping disc 60. A second sliding plate 62 is fixedly connected to the side of the second damping disc 63 away from the first damping disc 60. The second sliding plate 62 is externally sleeved with a third fixing frame 61. The third fixing frame 61 is fixedly connected with the box cover 15. The second damping disc 63 and the third fixing frame 61 are connected through a plurality of compression springs 64.

[0035] Through the design of the roller 54, it is convenient to move the whole device relative to the ground. Through the hydraulic telescopic rod 55, the second fixed frame 56 and the base 1 are driven to move vertically relative to the bottom plate 53. That is, the height of the first lower arc plate 2 and the second lower arc plate 5 can be changed according to the height of the pipe body 66. When it is needed to install the electric heat tracing band in the installation box 67, the worker drives the third bolt 65 to rotate, so that the third bolt 65 is separated from the installation box 67 and the box cover 15, and the locked fixing relationship between the box cover 15 and the installation box 67 is released. The worker drives the box cover 15 to move horizontally, and completes the removal of the box cover 15. The worker fixes and winds the electric heat tracing band on the end of the installation shaft 59 away from the first damping disc 60. The worker again passes the end of the electric heat tracing band from the inside of the installation box 67 to the outside of the installation box 67 through the discharge hole 57. The two material guide wheels 58 are respectively located on both sides of the electric heat tracing band. The worker again fixes the end of the electric heat tracing band on the pipe body 66. The worker drives the box cover 15 to move, so that the box cover 15 is moved to one side of the installation box 67 again. The worker drives the third bolt 65 to rotate, and locks and fixes the box cover 15 and the installation box 67 together again. When the installation box 67 rotates around the pipe body 66, the electric heat tracing band is wound outside the pipe body 66. At the same time, the electric heat tracing band pulls the installation shaft 59 and the first damping disc 60 to rotate, so as to reduce the length of the electric heat tracing band wound outside the installation shaft 59. Since the compressed spring 64 is in a compressed state in the initial state, the compressed spring 64 exerts pressure on the second damping disc 63, so that the second damping disc 63 presses one side of the first damping disc 60. Through the second damping disc 63, pressure is exerted on the first damping disc 60, which causes resistance to the rotation of the installation shaft 59 and the first damping disc 60, so that the electric heat tracing band wound outside the installation shaft 59 is in a tight state, avoiding the loosening of the electric heat tracing band wound outside the installation shaft 59.
