[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0026] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.
[0027] See also Figures 1 to 5 The utility model provides a heat network pipe patching device in an embodiment, which includes: a mounting semi-ring 1 and a semi-annular guide rail 2, wherein the mounting semi-ring 1 and the semi-annular guide rail 2 are each provided with two groups, and a support assembly 3 is arranged between the two groups of semi-annular guide rails 2.
[0028] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The support assembly 3 includes a support rail 31, the end of the support rail 31 is abutted against and slidably connected to the inner wall of the semi-annular guide rail 2, a sliding frame 32 is slidably mounted on the support rail 31, a support frame 33 is provided at the bottom of the sliding frame 32, a sliding frame 34 is slidably inserted into the interior of the sliding frame 32, the outer wall of the support rod in the sliding frame 34 is slidably connected to the inner wall of the support plate in the support frame 33, and a threaded baffle 341 is mounted on the outer wall of the support rod in the sliding frame 34.
[0029] It should be noted that when cutting the protective layer of the outer wall of the heat pipe, the staff can first control the movement of the baffle 341 in the support assembly 3 as needed to adjust the distance between the baffle 341 and the support frame 33. During this process, the staff can press the sliding frame 34 to make the sliding frame 34 drive the cutting disc below to move downward for cutting. When the baffle 341 is against the support frame 33, the movement of the sliding frame 34 can be limited, so that the cutting component can be moved later to make the cutting and grinding of the heat pipe wound more accurate.
[0030] In the embodiments of the present invention, please refer to Figure 1 and Figure 3 Each group of semi-annular guide rails 2 consists of two, and the annular guide rail formed by the two semi-annular guide rails 2 in the same group are fixedly connected by bolts. An insertion rod 21 is provided on the outer wall of the semi-annular guide rail 2, and a threaded limit cap 22 is sleeved on the outer wall of the insertion rod 21. Each group of mounting half rings 1 consists of two, and a threaded connecting rod 12 is inserted between the two mounting half rings 1 in the same group. A fixedly connected sliding guide rail 11 is provided on the outer wall of the mounting half ring 1, and the inner wall of the sliding guide rail 11 is abutted against and slidably connected to the outer wall of the insertion rod 21, and the outer wall of the sliding guide rail 11 is abutted against the end of the limit cap 22.
[0031] It should be noted that: by assembling the two semi-annular guide rails 2, the subsequent movement of the support guide rail 31 can be guided, and then during use, the support assembly 3 can drive the cutting component to rotate in a circle outside the heat pipe, so that the cutting disk or grinding head can cut and grind the bottom of the heat pipe, thereby improving the portability of the staff's cutting and grinding operations under the heat pipe.
[0032] In the embodiments of the present invention, please refer to Figure 1 and Figure 4A connecting piece 35 is provided at the bottom end of the sliding frame 34, and a driving motor 4 is rotatably connected to the bottom of the connecting piece 35 through a shaft 51, and a component for cutting and grinding the outer wall of the heat pipe is provided at the output end of the driving motor 4; a symmetrically distributed supporting piece 5 is provided at the bottom of the connecting piece 35, and the inner wall of the supporting piece 5 is rotatably connected to the outer wall of the shaft 51, and a fixedly connected connecting plate 52 is provided at the end of the shaft 51, and a limiting hole 53 is provided inside the connecting plate 52 and the supporting piece 5, and a threaded limiting rod 54 is inserted into the limiting hole 53.
[0033] It should be noted that: by using the shaft 51 to rotatably install the drive motor 4, the staff can adjust the output end angle of the drive motor 4 as needed during use, thereby improving the flexibility of the device in later use. By setting the limit rod 54, when the limit rod 54 is connected to the connecting plate 52 and the inside of the support plate 5 through the threaded structure, the shaft 51 can be limited, so the adjusted drive motor 4 can be stably supported by the shaft 51.
[0034] In the embodiments of the present invention, please refer to Figure 2 A spring 351 is arranged between the support plate in the support frame 33 and the connecting piece 35 , the top end of the spring 351 is fixedly connected to the bottom of the support plate in the support frame 33 , and the bottom end of the spring 351 is fixedly connected to the top of the connecting piece 35 .
[0035] It should be noted that: through the setting of the spring 351, in the initial state, the spring 351 can stretch the sliding frame 34 through its own force, so that the sliding frame 34 can drive the driving motor 4 and other components at the bottom to reset upward, thereby preventing the cutting disk or grinding head on the driving motor 4 from contacting the protective layer on the outer wall of the heat pipe in the initial state, which will affect the subsequent starting of the driving motor 4.
[0036] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 A fixedly connected protruding rod 36 is provided inside the sliding frame 32 , and a threadedly connected extruding cap 361 is sleeved on the outer wall of the protruding rod 36 , and the bottom of the extruding cap 361 abuts against the top of the supporting guide rail 31 .
[0037] It should be noted that: through the setting of the extrusion cap 361, during use, when the staff needs to control the sliding frame 32 to slide on the support guide rail 31, the extrusion cap 361 can be twisted to separate the extrusion cap 361 from the support guide rail 31, and the limit on the sliding frame 32 can be released, and then the driving motor 4 at the bottom can be driven to move by controlling the sliding of the sliding frame 32. Conversely, when the extrusion cap 361 is twisted, the sliding frame 32 can be fixed, so that when the staff controls the support guide rail 31 to slide inside the semi-annular guide rail 2, the sliding frame 32 can support the driving motor 4 more stably.
[0038] The working principle of the heat network pipe patching device provided by the utility model is as follows:
[0039] The staff can first take out the semi-circular guide rail 2 and assemble and fix the semi-circular guide rail 2 with bolts to form two symmetrically distributed circular guide rails 2. Then, the support assembly 3 can be taken out and the support rail 31 in the support assembly 3 can be pressed against the inner walls of the circular guide rails 2 on both sides.
[0040] Then the installation half ring 1 can be taken out, and the two installation half rings 1 on the same side can be preliminarily connected through the connecting rod 12. Then the installation half ring 1 can be moved so that the sliding guide rail 11 on its outer wall is inserted outside the insertion rod 21 of the outer wall of the semi-annular guide rail 2. After the limiting cap 22 is taken out and the limiting cap 22 is screwed on the outer wall of the insertion rod 21 to preliminarily fix the connection between the installation half ring 1 and the semi-annular guide rail 2, the connecting rod 12 can be continued to be screwed to fix the installation half ring 1 so that the installation half ring 1 is fixedly connected to the heat pipe. Finally, the limiting cap 22 can be screwed until the outer wall of the limiting cap 22 is against the outer wall of the sliding guide rail 11, and the installation half ring 1 can be connected to the semi-annular guide rail 2, thereby completing the installation of the device.
[0041] At this time, the staff can connect the cutting disc to be used with the driving motor 4. After the installation of the cutting disc is completed, the baffle 341 in the support assembly 3 can be controlled to move as needed to adjust the distance between the baffle 341 and the support frame 33. Then, the extrusion cap 361 can be controlled to move on the protruding rod 36 so that the bottom end of the extrusion cap 361 abuts against the top of the support guide rail 31 to fix the sliding frame 32. At this time, the staff can control the driving motor 4 to drive the cutting disc to rotate to cut the protective layer on the outer wall of the heat pipe.
[0042] During this process, the staff can press the sliding frame 34 to make the sliding frame 34 drive the cutting disc below to move downward for cutting. When the blocking piece 341 abuts against the supporting frame 33, the movement of the sliding frame 34 can be limited. Then, the staff presses the sliding frame 34 and applies a pulling force to it, so that the supporting guide rail 31 rotates inside the semi-annular guide rail 2, and the cutting depth of the cutting disc can be made more uniform when the annular cutting of the protective layer of the outer wall of the heat pipe is achieved.
[0043] The cutting position is adjusted by controlling the sliding frame 32 to move on the supporting rail 31. When the cutting and cleaning of the outside of the hot pipe wound is completed, the cutting disc can be disassembled and the grinding head can be replaced. Then, the driving motor 4 can be driven to rotate by the shaft 51 to adjust the output angle of the driving motor 4, so that the driving motor 4 can drive the grinding head to grind the surface of the cut outer protective layer of the hot pipe.
[0044] Finally, the rubber sheet used for repair can be taken out to cover and seal the outside of the treated heat pipe, and then the filler is injected and sealed inside the rubber sheet to complete the repair work on the damaged part of the heat pipe outside.
[0045] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
[0046] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
