Description

Technical Field

[0001] The utility model belongs to the technical field of directly buried heat-insulating pipes, and specifically relates to a steel-sheathed steel directly buried heat-insulating pipe. Background Art

[0002] The steel-sheathed steel directly buried heat-insulating pipe is an accessory device used in the process of material transportation to keep the material at its original temperature and transport it to a designated location. It is widely used in the field of material heat-insulating transportation. However, most of the existing heat-insulating pipes are directly welded to the conveying pipes during connection, so that the medium flowing in the pipe will come into contact with the weld, and the requirements for welding are relatively high.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.

[0031] Please refer to Figures 1-5, a steel-sheathed steel directly buried heat-insulated pipe, comprising a pipe body 1, in which a plurality of groups of sliding grooves are provided; a lead screw 31, which is arranged in the middle of the pipe body 1 and fixedly connected to the pipe body 1; a guiding component, which is arranged between the pipe body 1 and the lead screw 31 and is used to push the internal components to move; a cleaning component, which is arranged between the pipe body 1 and the lead screw 31 and is used to clean the inner wall of the pipe body 1. The cleaning component includes a cleaning plate 2 and a transmission block 3. The cleaning plate 2 abuts against the inner wall of the pipe body 1 and is threadedly connected to the lead screw 31. The transmission block 3 is arranged inside the pipe body 1 and is in transmission connection with the lead screw 31. The cleaning plate 2 is elastically connected to the transmission block 3. An expansion motor is installed inside the transmission block 3, and the output end of the expansion motor is fixedly connected to a sliding sleeve, which is threadedly connected to the lead screw 31. The cleaning component further includes a mounting block 21, which is arranged on the transmission block 3 and elastically connected to the transmission block 3. The cleaning plate 2 is rotatably connected to the mounting block 21. The cleaning component further includes a spring 22, which is arranged on the mounting block 21. One end of the spring 22 is fixedly connected to the mounting block 21, and the other end of the spring 22 is fixedly connected to the transmission block 3. Friction blocks 23 are arranged in an array on the cleaning plate 2 and are fixedly connected to the cleaning plate 2. The overall size of the friction blocks 23 is larger than the peripheral size of the cleaning plate 2. The expansion motor drives the sliding sleeve to rotate, and the sliding sleeve slides on the lead screw 31 through threaded transmission. The transmission block 3 pushes the cleaning plate 2 to slide. When the cleaning plate 2 slides, it is in threaded transmission with the lead screw 31 and rotates on the lead screw 31. While sliding, the cleaning plate 2 rotates and rubs against the inner wall of the pipe body 1. The impurities and scale on the inner wall of the pipe body 1 are removed by the friction between the cleaning plate 2 and the inner wall of the pipe body 1. The sliding grooves inside the pipe body 1 are cleaned by the staggered difference between the friction blocks 23 and the cleaning plate 2, avoiding the accumulation of impurities and scale in the sliding grooves, which may affect the use and cause the guide wheels 4 to fall off from the sliding grooves. When the transmission block 3 pushes the cleaning plate 2, the spring 22 is squeezed by the mounting block 21 and the transmission block 3, and the spring 22 deforms. The deformation of the spring 22 gives a force in the opposite direction of the movement of the mounting block 21 and the transmission block 3. When the cleaning plate 2 gets stuck on the inner wall of the pipe body 1, the spring 22 and the transmission block 3 shake the cleaning plate 2 with opposite forces, preventing the cleaning plate 2 from getting stuck inside the inner wall of the pipe body 1.

[0032] Among them, the guiding assembly includes an installation cylinder 32 and guiding wheels 4. The installation cylinder 32 is fixedly connected to the transmission block 3. A plurality of groups of guiding wheels 4 are movably connected to the installation cylinder 32. The plurality of groups of guiding wheels 4 are slidably connected to corresponding sliding grooves in the pipe body 1. The guiding assembly further includes a guiding block 41. The guiding block 41 is composed of two side plates. One end of the guiding block 41 is rotatably connected to the transmission block 3, and the guiding wheel 4 is rotatably connected to the other end of the guiding block 41. The guiding assembly further includes a hydraulic rod 42. The hydraulic rod 42 is arranged between the installation cylinder 32 and the guiding block 41. One end of the hydraulic rod 42 is rotatably connected to the installation cylinder 32, and the other end of the hydraulic rod 42 is rotatably connected to the guiding block 41. When the transmission block 3 slides, through the guiding wheel 4 and the guiding block 41, the guiding wheel 4 slides in the sliding groove in the pipe body 1 to guide and limit the transmission block 3, preventing the transmission block 3 from slipping and rotating in place in the pipe body 1. The hydraulic rod 42 pushes one end of the guiding block 41 to lift upward with the position of the transmission block 3 as the fulcrum, and the other end of the guiding block 41 drives the guiding wheel 4 upward, and the guiding wheel 4 is in close contact with the inner wall of the pipe body 1 to adapt to pipe bodies 1 of different sizes.

[0033] Working principle: The telescopic motor drives the sliding sleeve to rotate. The sliding sleeve slides on the lead screw 31 through screw transmission. The transmission block 3 pushes the cleaning plate 2 to slide. When the cleaning plate 2 slides, it is in screw transmission with the lead screw 31, and the cleaning plate 2 rotates on the lead screw 31 when it slides. The cleaning plate 2 rotates while sliding and rubs against the inner wall of the pipe body 1. The impurities and scale on the inner wall of the pipe body 1 are removed by the friction between the cleaning plate 2 and the inner wall of the pipe body 1. The sliding groove in the pipe body 1 is cleaned through the staggered difference between the friction block 23 and the cleaning plate 2, preventing the accumulation of impurities and scale in the sliding groove from affecting the use and preventing the guiding wheel 4 from falling off the sliding groove. When the transmission block 3 pushes the cleaning plate 2, the spring 22 is squeezed by the mounting block 21 and the transmission block 3, and the spring 22 deforms. The deformation of the spring 22 gives a force in the opposite direction of the movement of the mounting block 21 and the transmission block 3. When the cleaning plate 2 gets stuck on the inner wall of the pipe body 1, the spring 22 and the transmission block 3 shake the cleaning plate 2 with opposite forces to prevent the cleaning plate 2 from getting stuck in the inner wall of the pipe body 1. When the transmission block 3 slides, through the guiding wheel 4 and the guiding block 41, the guiding wheel 4 slides in the sliding groove in the pipe body 1 to guide and limit the transmission block 3, preventing the transmission block 3 from slipping and rotating in place in the pipe body 1. The hydraulic rod 42 pushes one end of the guiding block 41 to lift upward with the position of the transmission block 3 as the fulcrum, and the other end of the guiding block 41 drives the guiding wheel 4 upward, and the guiding wheel 4 is in close contact with the inner wall of the pipe body 1 to adapt to pipe bodies 1 of different sizes.
