Both ends of the protection baffle 4 are fixedly connected with fixed plates 11. A first spring 9 is fixedly connected between the middle ends of the fixed plates 11 and the middle end of the limiting frame 12.

[0026] In this technical solution, through the setting of the support frame 2, the pipe body 1 can be effectively erected. And through the setting of the arc-shaped baffle 3, a good limit protection can be formed on the top of the support frame 2 and around the pipe body 1, preventing the pipe body 1 from loosening from the top of the support frame 2 during the erection process.

And through the setting of the arc-shaped baffle 3, a good limit protection can be formed around the pipeline body 1 at the top of the support frame 2, avoiding the pipeline body 1 from becoming loose from the top of the support frame 2 during the erection process. At the same time, through the setting of the protective baffle 4, effective safety protection can be provided in the front of the pipeline body 1, avoiding the pipeline body 1 from being directly collided by objects during the erection and use process, resulting in damage, and improving the safety of the pipeline body 1 during use. And when maintenance operations need to be carried out on the pipeline body 1, by pushing the two limit frames 12 to move towards each other, while the movement of the limit frames 12 compresses the first spring 9 on the fixed plate 11, until the limit frames 12 can be disengaged from the inner cavities of the first fixed sleeve 6 and the second fixed sleeve 13 respectively, personnel can remove the protective baffle 4 from the front of the pipeline body 1, thus facilitating the maintenance operation of the pipeline body 1 by personnel and bringing great convenience to the work of personnel.
