Embodiment 1
[0033] A fast-adjusting support device for large-diameter low-temperature pipelines, such as figure 1 As shown, it includes a cylinder body 1, a piston assembly 2, a strut 5, a pipe holder 6, a connecting pipe 9, a regulating valve 8 and a hydraulic source 11;
[0034] Wherein the bottom of the cylinder body 1 is a flange, first the present invention is fixed on the corresponding position of the pipeline to be supported by the flange, to ensure the stability of the device, the top of the cylinder body 1 is open; the piston assembly 2 is slidably connected inside the cylinder body 1, and the An O-ring 7 is arranged between the assembly and the inner wall of the cylinder, and a liquid chamber 14 is formed between the bottom of the cylinder 1 and the piston assembly 2; 5; one end of the connecting pipe 9 communicates with the liquid chamber, and the other end communicates with the hydraulic pressure source 11 through a regulating valve 8.
[0035] Open the regulating valve 8, an...
Embodiment 2
[0037] Such as figure 2 As shown, on the basis of Embodiment 1, the piston assembly 2 in the cylinder 1 has been optimized as follows. The piston assembly 2 includes an upper cover plate 12, a lower cover plate 13, a spring 3, a screw rod 4 and a nut 10 , the upper cover plate 12 and the lower cover plate 13 are arranged in parallel inside the cylinder body 1, the spring 3 is installed between the upper cover plate 12 and the lower cover plate 13, one end of the screw rod 4 is fixedly connected with the lower cover plate 13, and the other end passes through the upper cover plate 13. The cover plate 12 is then threaded through the nut 10 . It should be noted that in this embodiment there are two O-rings 7 , which are respectively arranged between the upper cover plate 12 and the cylinder body 1 and between the lower cover plate 13 and the cylinder body 1 .
[0038] When the pipe is located on the pipe support 6, the pipe will give a certain pressure to the piston assembly 2 t...
Embodiment 3
[0040] Such as image 3 As shown, on the basis of Embodiment 2 and / or Embodiment 1, the support rod 5 of the present invention is threadedly connected to the pipe support 6, and the relative position of the support rod 5 and the pipe support 6 can be further adjusted by threading to further adjust the support structure height to achieve the desired support effect.
[0041] The working principle / working process of the regulating device is described as follows:
[0042] First, adjust the position of the nut on the screw so that the spring is in a natural state.
[0043] Secondly, open the regulating valve, use the hydraulic source to fill the liquid chamber in the cylinder body with liquid, so that the piston assembly drives the rod and the pipe support to move upward to contact with the pipeline, and then continue to add liquid until the spring is compressed and deformed, so that the upper There is a certain gap between the cover plate and the nut, after which the filling of ...
