[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0022] First embodiment:

[0023] See also Figure 1-Figure 2 As shown, the utility model provides a tunnel fire protection pipeline antifreeze heating device, comprising a heating frame 1, the heating frame 1 comprises an arc panel 101 with an upper opening, the inner wall of the arc panel 101 is provided with a heating wire 103 for heating the pipeline, the heating wire 103 is distributed in a continuous serpentine shape, and is embedded and installed on the inner wall of the arc panel 101;

[0024] The high end of the heating frame 1 is rotatably connected to a clamping arm 4, and the clamping arm 4 is symmetrically arranged on both sides of the heating frame 1. The movable end of the clamping arm 4 is rotatably connected to a rotating wheel 401 corresponding to the pipeline; when the device is in use, the clamping arm 4 is rotated to make the rotating wheel 401 corresponding to the upper part of the pipeline, and the arc panel 101 is corresponding to the bottom of the pipeline. After the heating wire 103 is powered on and heated, the pipeline can be heated. At this time, the rotation of the rotating wheel 401 can assist the movement of the device, which is convenient for heating and antifreezing the entire fire-fighting pipeline. In addition, during the movement, the rotation of the device can make the vacant position between the two rotating wheels 401 correspond to the bracket of the hoisting pipeline, so that the pipeline can be clamped through the hoisting frame, thereby assisting the device to heat the entire fire-fighting pipeline. The device has a simple structure and good use effect.

[0025] Furthermore, the clamping arm 4 is rotationally connected to the rotation point of the plate 102 by bolts.

[0026] Preferably, the cross section of the arc panel 101 is a semi-annular or semi-annular structure;

[0027] Flat plates 102 are provided on both sides of the opening of the arc panel 101. The flat plates 102 are in a strip-shaped structure. The clamping arms 4 are rotatably connected to the flat plates 102, and the clamping arms 4 are supported by the flat plates 102. No less than two clamping arms 4 are rotatably connected to each flat plate 102, and multiple clamping arms 4 can be used to assist the device in moving smoothly on the outside of the pipeline.

[0028] The second embodiment is different from the first embodiment in that:

[0029] A torsion spring is provided at the rotation point between the clamping arm 4 and the flat plate 102. The elasticity of the torsion spring can push the clamping arm 4 to rotate toward the pipe inside the arc plate 101; the rotating wheel 401 is made of rubber.

[0030] The third embodiment is different from the first embodiment in that:

[0031] The outer side of the arc panel 101 is connected with a heat preservation layer 2, and the outer wall of the heat preservation layer 2 is provided with a waterproof heat insulation layer 3. The heat preservation layer 2 and the waterproof heat insulation layer 3 play the role of heat preservation and isolation.
