Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of building engineering, concretely relates to a kind of fabricated pipeline support and monitoring device. BACKGROUND

[0002] In the process of engineering pipeline installation, the connection between pipeline and support is very important, the connecting device not only bears the load of pipeline self weight and its conveying material, but also needs to bear the temperature stress of pipeline and wind load, snow load, and effectively transmit all loads to pipeline support. At the same time, it also needs to meet the displacement of pipeline generated by various loads, and keep the whole pipe network system force balanced and stable.

[0003] Overhead pipeline support can be divided into fixed support and sliding support according to stress condition and whether relative displacement is generated between pipeline and support, under the premise of meeting load action, fixed support requires no relative displacement between pipeline and support (usually realized by welding), while sliding support allows relative displacement between pipeline and pipeline support. The functional characteristics of sliding support make the connection between pipeline and support more complex, mainly in the following aspects:

[0004] Firstly, the relative displacement generated between pipeline and support needs to be limited, too large or too small displacement will make pipeline structure safety face risks, and may cause pipeline expander damage, and pipeline stress and displacement will deviate from theoretical calculation and engineering actual installation due to the action of various external factors. After pipe network is put into use, it is necessary to regularly calculate and monitor pipeline stress and displacement state in real time if necessary, and there is no related device to realize this function at present.

[0005] Secondly, the displacement between pipeline and support is mainly realized in the form of relative sliding, for larger diameter pipeline, due to larger vertical load, it will cause very large sliding friction force between pipeline and support, and friction will cause component wear, and also affect pipeline safety. The connecting device between pipeline and support is closely related to pipeline normal service life and pipeline operation and maintenance cost.

[0006] The existing pipe support mainly has the following deficiencies: 1. The pipe support is welded by steel plates and section steels in the factory according to the diameter of the installed pipeline, the form and specification of the pipe support are fixed, the pipe support is transported to the site after welding for installation and is used in combination with the pipeline, and the pipe support does not belong to the assembled structure, and the flexibility in adaptability is insufficient; 2. In order to meet the horizontal displacement of the pipeline, the steel pipe support is placed on the top beam of the support (a polytetrafluoroethylene plate is arranged at the lower part of the pipe support), the pipeline slides on the top beam of the support together with the pipe support, or the pipeline directly slides on the upper part of the pipe support. Since the pipeline has a large weight, the sliding friction force is also large, and repeated friction can easily cause wear of the pipe wall or the pipe support component, thereby affecting the service life of the pipeline; 3. The pipe support does not have a real-time monitoring function for the stress state of the pipeline, and the pipeline load and displacement cannot be monitored and warned in real time. When the support foundation settles, the support deforms or the pipeline expander fails, a safety accident is prone to occur due to the failure of timely warning; 4. The pipe support cannot be recycled and reused, and it is very difficult to maintain and replace after the installation and construction are completed. Content of the utility model

[0008] In order to realize the above-mentioned purpose, the technical scheme that the utility model adopts is as follows:

[0010] Preferably, a tie rod is arranged at the other end between the end plates, and an adjusting screw pipe is arranged at the middle position of the tie rod.

[0011] Preferably, a gas monitor and a deformation monitor are installed at one end of the end plate where the tie rod is arranged.

[0012] Preferably, the roller disc is a cylindrical structure with a thin middle and thick ends.

[0013] Preferably, a bearing is arranged between the roller disc and the shaft rod, a clamping groove is arranged on the shaft rod, a buckle is arranged on the bearing, and the buckle on the bearing is connected to the shaft rod in a matched mode through the clamping groove.

[0015] The utility model discloses heat beneficial effect is:

[0016] (1) unlike the existing steel pipe base, the support structure is assembled by multiple components, has the assembly structure characteristics of few components, multiple combinations, various specifications of assembly components can be processed and assembled on site according to the actual installation needs of pipeline, such as the support structure can be combined according to the diameter of the installed pipeline, selects different roller discs to meet the installation needs of different diameter pipelines.

[0017] (2) the support structure uses roller disc combination component to replace the traditional steel pipe base, when the pipeline generates displacement along the pipeline laying direction, the roller disc generates rolling, and the friction coefficient of the roller is very small, and the traditional sliding friction is replaced by rolling friction, which not only reduces the friction generated when the pipeline displaces, but also reduces the wear and tear of the pipeline wall or component, improves the service life of the pipeline, when the pipeline generates horizontal displacement along the vertical direction of the pipeline, the spring will shrink, and the related load data is collected through the pressure sensor.

[0032] In use, first, the specifications and sizes of the roller disc 1, the shaft rod 2, the spring 3, the end plate 4, the tie rod 5, the adjusting screw pipe 6, the fixing bolt 7 and the like are determined according to the load, and the machining is completed in the factory; the appropriate roller disc 1 is selected according to the diameter of the pipeline 14 and is combined; the end plate 4 is installed on the pipeline foundation or the top of the pipeline support through the fixing bolt 7, the shaft rod 2 and the tie rod 5 are installed on the end plate 4 through the bolt, the shaft rod 2 is installed by penetrating the roller disc 1 and the springs 3 on both sides of the roller disc 1, the pressure sensor 8 is installed on both sides of the spring, and the rod 2 is installed on the two end plates 4; the length of the tie rod 5 is adjusted through the adjusting screw pipe 6, and the two tie rods 5 are connected and fixed with the end plate 4, and the tie rod 5 can stabilize the entire device; the deformation monitor 9 and the gas monitor 10 are installed at the end plate 4; the fixing bolt 7 at the bottom of the end plate 4 is fastened, and the device is fixed on the top surface of the support pier or the support; the pipeline 14 is placed on the roller disc 1, and the support is completed; when the support structure is removed, all the components can be removed in the reverse order, and the components can be recycled.

[0034] 1. The roller disc 1 is a series of steel sheet discs with different diameters, and the discs with different diameters are combined to match the bottom surface of the pipeline, so that good support can be formed on the pipeline. When the pipeline is displaced along the pipeline laying direction, the roller disc can rotate around the shaft rod.
