Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figures 1-3 In this embodiment of the utility model, a fixing structure that facilitates pipe cutting includes auxiliary fixing components 2 installed on both sides of the cutting position of the pipe 1 to be cut. The auxiliary fixing components 2 are used to fix and support the cut pipe section 102. The auxiliary fixing component 2 includes a clamping unit and a support connection unit; Two sets of clamping units are clamped and fixed to the outside of the retained pipe 101 and the cut pipe section 102 respectively, with the cutting line of the pipe to be cut as the center. The support connection unit is connected to the clamping unit and is used to transfer the weight of the cut pipe section 102 to the retained pipe 101 to achieve stable support of the cut pipe section 102. The clamping unit includes a U-shaped clamp 201, a semi-circular connecting seat 202, a fixed connecting seat 203, a straight slot 204, an arc-shaped clamp 205, an arc-shaped connecting seat 206, a T-shaped slide 207, and a clamping screw 211; The semi-circular connecting seat 202 is fixed to the outer side of the arc-shaped part of the U-shaped sleeve 201, and the fixed connecting seat 203 is symmetrically fixed to the upper and lower ends of the U-shaped sleeve 201 and fixedly connected to the end of the semi-circular connecting seat 202. The straight slots 204 are symmetrically opened at the upper and lower ends of the two straight sections of the U-shaped sleeve 201 and completely penetrate the straight sections of the U-shaped sleeve 201. The arc-shaped connecting seat 206 is fixed to the outside of the arc-shaped sleeve 205. The T-shaped slide 207 is symmetrically fixed to the upper and lower ends of the arc-shaped sleeve 205 and the arc-shaped connecting seat 206. The U-shaped sleeve 201 is sleeved on the outside of the pipe 1 to be cut from one side. The arc-shaped sleeve 205 is sleeved on the outside of the pipe 1 to be cut from the other side. It is slidably connected to the straight groove 204 through the T-shaped slide 207. The T-shaped slide 207 and the fixed connecting seat 203 have relatively aligned transverse through holes 208. The clamping screw 211 passes through the transverse through holes 208 on the fixed connecting seat 203 and the T-shaped slide 207 in sequence and is tightened with a nut to achieve clamping and fixing of the U-shaped sleeve 201, the arc-shaped sleeve 205 and the pipe 1 to be cut. The support connection unit includes a longitudinal through hole 210 and a support connection rod 212; A longitudinal through hole 210 is formed at one end of the semi-circular connecting seat 202 and the arc-shaped connecting seat 206 and completely penetrates the other end of the semi-circular connecting seat 202 and the arc-shaped connecting seat 206; The support connecting rod 212 is distributed between two symmetrically distributed semi-circular connecting seats 202 or two arc-shaped connecting seats 206, and studs are fixed at both ends of the support connecting rod 212. The studs pass through the longitudinal through hole 210 and are tightened with nuts to realize the connection and fixation of the two sets of clamping units.

[0014] In this embodiment: when cutting the pipe with a tracked wire saw, the pipe section 102 being cut is supported and fixed by the auxiliary fixing component 2 to improve operational safety. The operation method is as follows: First, connect and fix the two semi-circular connecting seats 202 and the two arc-shaped connecting seats 206 through the support connecting rod 212. Then, pass the studs at both ends of the support connecting rod 212 through the corresponding longitudinal through holes 210 and tighten them with nuts. Figure 2 ); Next, the clamping screw 211 is first passed through the transverse through hole on the fixed connecting seat 203, and then tightened with the nut to fix the clamping screw 211 to the clamping screw 211. Then, the assembled two semi-circular connecting seats 202 are hoisted as a whole to one side of the pipe 1 to be cut using hoisting equipment, so that the opening of the U-shaped sleeve 201 is aligned with the pipe 1 to be cut. Then, it is moved horizontally so that the U-shaped sleeve 201 is fitted onto the outside of the pipe 1 to be cut, and the two U-shaped sleeves 201 are respectively fitted onto the outer wall of the retained pipe 101 and the pipe section 102 to be cut, with the cutting line as the center (e.g., Figure 1 ); Next, the two assembled arc-shaped connecting seats 206 are hoisted to the other side of the pipe 1 to be cut using another hoisting device, so that the T-shaped slide 207 is aligned with the straight groove 204 and inserted horizontally. During this process, the T-shaped slide 207 is sleeved on the outside of the clamping screw 211 through the transverse through hole 208, and then connected to the clamping screw 211 through another set of nuts and threads to press the T-shaped slide 207. In this way, the U-shaped sleeve 201, the arc-shaped sleeve 205 and the pipe 1 to be cut are clamped and fixed. Afterwards, the cutting operation can be carried out. When the cut pipe section 102 and the retained pipe 101 are completely separated, the weight of the cut pipe section 102 is transferred to the retained pipe 101 through the auxiliary fixing components 2, so that the cut pipe section 102 remains stable and effectively avoids the catastrophic consequences caused by the sudden rolling, sliding or displacement of the cut pipe section 102. It should also be noted that during the cutting process, the middle position of the cut pipe section 102 is also hoisted by the hoisting equipment, so as to realize the weight distribution of the cut pipe section 102. That is, the overall weight of the cut pipe section 102 is shared by the two sets of auxiliary fixing components 2 and the hoisting equipment.

[0015] Please refer to this carefully. Figures 1-3 The semi-circular connecting seat 202 and the arc-shaped connecting seat 206 have multiple longitudinal through holes 210 evenly arranged along the circumference, and the supporting connecting rod 212 does not contact the outside of the pipe 1 to be cut.

[0016] In this embodiment: by cooperating with the support connecting rod 212 through multiple sets of annularly distributed longitudinal through holes 210, multi-directional limiting of the cut pipe section 102 can be achieved; By ensuring that the support connecting rod 212 does not contact the outside of the pipe 1 to be cut, the wire saw is located inside the distribution trajectory of multiple support connecting rods 212, so that the support connecting rod 212 does not affect the cutting operation of the tracked wire saw. In addition, the support connecting rod 212 may not be installed at the position that is aligned with the final detachment position of the tracked wire saw, so as to avoid obstructing the detachment of the wire saw.

[0017] Please refer to this carefully. Figures 1-3 The top of the fixed connecting seat 203 and the T-shaped slide 207 are both fixed with lifting lugs 209, and there are two lifting lugs 209 arranged symmetrically at the top and bottom.

[0018] In this embodiment: the lifting lugs 209 provide a mounting position for hoisting. In addition, the symmetrically distributed lifting lugs 209 eliminate the need to consider the vertical orientation when installing the auxiliary fixing component 2, making the installation operation simpler.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
