Description

Technical Field

[0001] The utility model belongs to the technical field of water delivery engineering, and in particular relates to a pipe-following cable erection structure for open-laid pipelines. Background Art

[0002] In recent years, with the development of automation control related applications, the requirements for the degree of automation of various projects in engineering have been continuously improved. Important long-distance water transmission projects require the ability to realize automatic detection and control of the later operating status, so it is necessary to equip relevant automatic control and power systems in advance during the construction of the project. In addition to purchasing and installing electric control valves with various functions and pressure, flow and other detection instruments, the laying of pipe-mounted cables or optical cables should also be considered. The water source of large-scale water supply projects often comes from deep mountains or deserts. Because it is an uninhabited area, there is a lack of infrastructure such as electricity and communications. Especially when the water pipeline passes through steep slopes in the mountains, the project needs to build its own pipe-mounted cables and communication optical cables.

[0003] At present, most projects adopt the method of placing cables anywhere and fixing them locally when laying open pipes, or directly installing them close to the pipes with clamps. However, the method of placing cables anywhere will cause the cables to be washed by floods or soaked in water during the rainy season, which poses a safety hazard and reduces the service life of the cables; when the clamps are installed close to the pipes, when the pipe diameter is too large, it is not only inconvenient to install, but also the clamps consume a lot of materials, which is not economical; especially when the pipe is made of metal pipes, the installation method of the clamps on the outer wall of the pipe is prone to safety problems after local damage, and stray currents linger around the pipes, which is easy to cause local electrochemical corrosion and damage the pipe structure. Utility Model Content

[0004] The purpose of the utility model is to provide a pipe-mounted cable installation structure for open-laid pipelines, which can well avoid the above problems. At the same time, the structure is not affected by the pipe material and pipe diameter of the pipeline in the project, and has the advantages of easy installation, stable structure, and saving investment and construction period.

[0005] The technical solution adopted by the utility model is a cable installation structure for exposed pipelines, including a cable threading sleeve and a plurality of fixed support components, the fixed support components including embedded parts, a support platform and a movable nut structure pipe clamp, the embedded parts are fixedly embedded in the vertical surface of one side of the pier, the support platform is fixedly connected to the embedded parts, the movable nut structure pipe clamp is fixedly installed on the support platform and there are no less than two of them, the cable threading sleeve is inserted into the movable nut structure pipe clamp, and the cable is inserted into the cable threading sleeve.

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer and more understandable, the technical solution of the utility model will be further described in detail below with reference to the accompanying drawings.

[0020] When long-distance water pipelines are laid in the open, multiple concrete piers 1 are usually set between two anchor piers of the open pipeline, and the pipeline is laid on the piers 1. The layout of the piers 1 is often related to the length of the pipe section of the pipeline 115 and the structural strength of the pipeline 115 itself. Usually, the spacing between the piers 1 is 6-12m.

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, in water supply and irrigation projects, for the exposed pipelines in the mountains with steep terrain and inconvenient transportation, a pipe trench exposed pipeline structure is often used. The pipe trench exposed pipeline structure is a pipe trench 111 provided at the bottom of the pipeline 115, and the pipe trench 111 includes a drainage ditch 112, a maintenance channel step 113 and a pipe support 114. The concrete pipe trench structure can well ensure the structural safety and stability of the exposed pipeline on the hillside, and the maintenance channel step 113 can take into account the inconvenience of operation and maintenance of the mountain pipeline in the later stage.

[0022] like Figure 4 , Figure 5 , Figure 6 As shown, the utility model provides a cable installation structure for exposed pipelines, including a cable sleeve 3 and a plurality of fixed support components, the fixed support components including embedded parts 6, a support platform and a movable nut structure pipe clamp 4, the embedded parts 6 are fixedly embedded in a side facade of the pier 1, the support platform is fixedly connected to the embedded parts 6, the movable nut structure pipe clamp 4 is fixedly installed on the support platform and there are no less than two of them, the cable sleeve 3 is inserted into the movable nut structure pipe clamp, and the cable 2 is inserted into the cable sleeve 3.

[0023] The pipeline 115 is arranged at the top of the pier 1, and the cable installation structure with the pipe in the utility model is arranged on the side of the pier 1, and preferably, the cable installation structure with the pipe is arranged on the side of the pier 1 away from the maintenance channel step 113 to avoid obstructing the passage of people on the maintenance channel step 113 and reduce safety hazards.

[0024] The number of fixed support components on the same pier 1 is preferably two, which is not only practical and reliable but also economical.

[0025] A plurality of hooks 7 are embedded on one side of the pier 1, and the embedded parts 6 are fixedly connected to the hooks 7 and arranged in a vertical state. The hooks 7 can position and fix the embedded parts 6, and the embedded parts 6 serve as fixed installation fulcrums of the support platform.

[0026] The support platform includes a horizontal support channel steel 5, an oblique support I-beam 8 and a vertical support channel steel 10. The vertical support channel steel 10 is fixedly connected to the embedded part 6 and is arranged in a vertical state. The horizontal support channel steel 5 is fixedly connected to the vertical support channel steel 10 and is arranged in a horizontal state. One end of the oblique support I-beam 8 is fixedly connected to the vertical support channel steel 10 and the other end thereof is fixedly connected to the horizontal support channel steel 5.

[0027] The horizontal support channel steel 5, the vertical support channel steel 10 and the diagonal support I-beam steel 8 are welded and fixed to each other to form a triangle, and the stable structure of the triangle is used to support the movable nut structure pipe clamp 4.

[0028] The movable nut structure pipe clamp 4 includes an arc plate 41 and two mounting plates 42. The two mounting plates 42 are symmetrically fixed at both ends of the arc plate 41. The mounting plates 42 are fixedly connected to the horizontal support channel steel 5 by bolts and nuts. The cable sleeve 3 is inserted into the arc plate 41.

[0029] The two mounting plates 42 are arranged at both ends of the arc plate 41 and are fixedly connected to the horizontal support channel steel 5 , which can prevent the ends of the arc plate 41 from tilting up, thereby preventing the cable 2 from being installed unstably.

[0030] A foam filler 91 is inserted into the cable insertion sleeve 3 , and a plurality of reserved square holes 92 are formed on the foam filler 91 , and the cables 2 are inserted into the reserved square holes 92 .

[0031] The foam filler 91 can provide buffering protection for the internal cables 2 and effectively protect the force points of the cables 2 from being damaged by external forces; the reserved square holes 92 in the foam filler 91 should be evenly arranged so that multiple cables 2 are evenly laid out without entanglement or interference.

[0032] To sum up, the installation process of the utility model is as follows: first, a hook 7 is set in the side of the pier 1 under the pipeline 115, and then the embedded part 6 is embedded in the pier 1 and welded to the hook 7, then the vertical support channel steel 10 is welded to the embedded part 6, and then the horizontal support channel steel 5 is welded to the vertical support channel steel 10, and then the two ends of the diagonal support I-beam 8 are respectively welded to the horizontal support channel steel 5 and the vertical support channel steel 10.
