[0030] A limiting piece 315 is fixed to the upper end of the support bottom plate 313. The limiting piece 315 and the support bottom plate 313 are integrally arranged. A support nut 316 is sleeved on the surface of the support screw 312. The support nut 316 is located below the support foot 311. Through this design, it is convenient for the limitation of the support foot 311 and the support screw 312, convenient for the stable support of the support screw 312 and the support foot 311, convenient for long-term placement, and making the use more convenient.

[0031] Working principle:

[0032] When it is necessary to support and position multiple pipes according to the orientation direction during pipeline prefabrication construction, after moving the steel pipe frame 111 to a suitable position through the universal wheels 112, rotate the support screw 312. Under the threaded insertion connection of the support foot 311, it is convenient for the support screw 312 to drive the support bottom plate 313 to contact the ground or the operating table. With the cooperation of the convex pad 314, it is convenient for the stable placement and support of the support bottom plate 313, so that the support bottom plate 313 can stably support the steel pipe frame 111 under the cooperation of the support screw 312 and the support foot 311, making the steel pipe frame 111 relatively stationary and convenient for subsequent positioning operations.

[0033] Subsequently, the support nut 316 is screwed upward and onto the bottom end of the support foot 311, facilitating the limitation of the support foot 311 and the support screw 312 by the support nut 316, making it difficult for the support screw 312 to reverse, and facilitating the stable support of the support base plate 313 for the steel pipe frame 111; when movement is required, first rotate the support nut 316 downward; then reverse the support screw 312, facilitating the retraction of the support base plate 313, so that the steel pipe frame 111 is convenient to move with the cooperation of the universal wheels 112; with the cooperation of the limit piece 315, it is convenient to limit the support nut 316 and avoid wire stripping.

[0034] When the steel pipe frame 111 is stationary at a suitable position, adjust the support frame 212 according to the direction and orientation of the prefabricated pipe. Pinch one end of the adjusting screw 222 close to the hoop 225, so that the adjusting screw 222 can only move back and forth and cannot rotate left and right; hold the handle 229 and rotate it, facilitating the rotation of the adjusting nut 223. Under the threaded sleeve connection between the adjusting nut 223 and the adjusting screw 222, the adjusting screw 222 is convenient to extend and retract inside the support pipe 221, and is convenient to drive the hoop 225 to move and adjust the height with the cooperation of the support claw 224; when the adjusting nut 223 rotates, through the clamping of the snap ring 227, it is convenient to limit and support the adjusting nut 223, making the extension and retraction of the adjusting screw 222 inside the support pipe 221 more convenient;

[0035] After adjusting the height, screw the fastening nut 228 tightly towards the adjusting nut 223. With the opposite settings of the surface threads of the adjusting screw 222 and the support pipe 221, it is convenient for the fastening nut 228 to lock the adjusting nut 223, making subsequent operations more convenient; similarly, during adjustment, with the cooperation of the ball 226, it is convenient to adjust the orientation of the hoop 225, and then it is convenient for subsequent welding with the sleeving and assembly of the hoop 225; at the same time, according to different pipe diameters, with the support claw 224 and the hoop 225 assembled by a pin, it is convenient to replace the hoop 225 with the corresponding diameter.

[0036] When clamping the pipeline, through the maintenance of the gasket 230, it is convenient for the maintenance of the pipeline surface and is not easy to cause scratches and other traumas; during operation, according to the horizontal distance between the pipeline and the hoop 225, with the cooperation of the slide rail 235 and the adjustment groove 236, it is convenient for the locking pin 231 to drive the slider 219 and the support seat 220 to slide, so that the hoop 225 can slide to a suitable position; during sliding, with the cooperation of the friction force of the frosted sleeve 234, it is convenient for the smooth sliding of the slider 219; after reaching the appropriate position, tighten the locking nut 232. With the cooperation of the locking gasket 233, the tightening operation is more convenient, which is convenient for the sliding limit fixation of the hoop 225 and makes the subsequent positioning operation more convenient; at the same time, according to the number and orientation of the pipelines, it is convenient to open the cross beam frame 211, the side beam frame 213 and the bottom beam frame 214 with the cooperation of the assembly bolts 217 and the assembly angles 218, separate the beam shell one 215 and the beam shell two 216, and it is convenient to clamp and assemble the corresponding number of support frames 212 inside them, so that the steel pipe frame 111 is convenient for three-dimensional multi-directional multi-pipeline positioning and support in space, which is convenient for subsequent construction needs and improves construction efficiency. The operation ends here.

[0037] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
