Technical Field
[0001] This utility model relates to the field of guiding and positioning technology, specifically a steel-clad steel steam direct-buried pipe guide and positioner. Background Technology
[0002] The main structure of a steel-jacketed steam direct-buried pipe consists of a working pipe, an insulation layer, and an outer anti-corrosion steel pipe. During installation, the insulated working pipe needs to be pushed into the outer steel pipe.
[0003] For example, a steel-clad steam direct-buried pipe guide and locator with authorization announcement number CN220902432U includes: a positioning component, a handle crossbar, universal component one, universal component two, and a reinforcing support plate. The handle crossbar is welded to the lower front side of the positioning component, universal component one is welded to the lower left side of the positioning component, and positioning component two is welded to the lower right side of the positioning component. However, the above document still has shortcomings. In use, the positioning component, together with universal component one and universal component two, forms the main body, which has a simple and practical structure and provides support during pipe installation. The positioning function ensures concentricity during the steel-jacketed steam direct burial pipe installation process, solving problems such as insulation layer damage and detachment, and outer casing wear during pipe installation, thus improving the efficiency of steel-jacketed steam direct burial pipe installation. However, the guide positioner in the aforementioned document only supports the lower part of the steel-jacketed steam direct burial pipe when guiding and positioning it. The steel-jacketed steam direct burial pipe is prone to tilting when subjected to external forces. At the same time, it is not convenient to adjust the height of the guide positioner according to actual usage requirements when guiding and positioning the steel-jacketed steam direct burial pipe.

[0014] This utility model proposes a guide and positioner for steel-jacketed steam direct-buried pipes. The advantages are as follows: Through the cooperation of a worm gear, a first rotating wheel, a worm wheel, a pin, a support rod, a first bracket, and rollers, the steel-jacketed steam direct-buried pipe is inserted into the interior of the circular pipe. Rotating the first rotating wheel drives the worm gear, which in turn drives the worm wheel. The worm wheel, through an internal groove, drives the pin, which in turn drives the support rod, which in turn drives the first bracket. The first bracket then drives the rollers, which are in contact with the outer wall of the steel-jacketed steam direct-buried pipe. The position of the steel-jacketed steam direct-buried pipe corresponds to the position of the outer steel pipe. Pushing the steel-jacketed steam direct-buried pipe, it is inserted into the interior of the outer steel pipe.

When the screw rotates, its vertical height changes under the action of the threaded block. The height of the second bracket changes with the screw, the frame changes with the height of the second bracket, and thus the height of the steel-clad steam direct-buried pipe changes. After adjusting the steel-clad steam direct-buried pipe to the required height, the second rotating wheel is stopped, the connecting rod is released, and the spring drives the connecting rod to slide in the opposite direction under the elastic action. The end of the connecting rod is inserted into the inside of the slot, and the positions of the second bracket and the third bracket are relatively fixed. Thus, the height of the steel-clad steam direct-buried pipe is fixed. When guiding and positioning the steel-clad steam direct-buried pipe, it is convenient to adjust the height of the guide positioner according to the actual use requirements.

When guiding and positioning the steel-clad steam direct-buried pipe, it is convenient to adjust the height of the guide positioner according to the actual use requirements.
[0029] Working principle:
[0030] When using the steel-jacketed steam direct-buried pipe guide positioner to guide and position the insulated steel-jacketed steam direct-buried pipe into the inner part of the outer steel pipe, the guide positioner is pushed to the required position and fixed. The steel-jacketed steam direct-buried pipe is then placed into the inner part of the circular pipe 2. The first rotating wheel 302 is rotated, which drives the worm 301 to rotate. The worm 301 drives the worm wheel 303 to rotate. The worm wheel 303 drives the pin 304 to move through the internal sliding groove. The pin 304 drives the support rod 305 to move.

[0031] Height adjustment phase:
[0032] When the height of the steel-jacketed steam direct-buried pipe needs to be adjusted based on the height difference between the outer steel pipe and the inner steel pipe, the connecting rods 12 on both sides are pulled (two workers operate simultaneously on both sides). The ends of the connecting rods 12 separate from the slots 14, and the connecting rods 12 compress the springs 13, rotating the second rotating wheel 403. The second rotating wheel 403 drives the rotating rod 402 to rotate, which in turn drives the first bevel gear 404 to rotate. The first bevel gear 404 drives the second bevel gear 405 to rotate, which in turn drives the screw 406 to rotate. When the screw 406 rotates, its vertical height changes under the action of the threaded block 407. The height of the second bracket 401 changes with the screw 406, the frame 401 changes with the height of the second bracket 401, and thus the height of the steel-jacketed steam direct-buried pipe changes. After adjusting the steel-jacketed steam direct-buried pipe to the required height, stop rotating the second rotating wheel 403, release the connecting rod 12, and the spring 13 drives the connecting rod 12 to slide in the opposite direction under the elastic action. The end of the connecting rod 12 is inserted into the inside of the slot 14, and the positions of the second bracket 401 and the third bracket 408 are relatively fixed, thus fixing the height of the steel-jacketed steam direct-buried pipe. When guiding and positioning the steel-jacketed steam direct-buried pipe, it is convenient to adjust the height of the guide positioner according to the actual use requirements.
[0033] Guided stage of steel-jacketed steam direct-buried pipe:
[0034] The position of the steel-jacketed steam direct-buried pipe corresponds to the position of the outer steel pipe. Pushing the steel-jacketed steam direct-buried pipe, the steel-jacketed steam direct-buried pipe is inserted into the interior of the outer steel pipe. The rollers 307 play a guiding and positioning role in the movement of the steel-jacketed steam direct-buried pipe. Multiple rollers 307 are provided to guide and position the steel-jacketed steam direct-buried pipe in multiple directions. The steel-jacketed steam direct-buried pipe is not easy to tilt when subjected to external force, thus realizing the guiding and positioning of the steel-jacketed steam direct-buried pipe through the pipe.
