Description

Technical Field

[0001] The invention belongs to the field of construction engineering, and in particular relates to an assembled pipeline support and monitoring device. Background Art

[0002] During the installation of engineering pipelines, the connection between the pipeline and the bracket is very important. The connection device not only bears the weight of the pipeline and the load of the material it transports, but also needs to bear the pipeline temperature stress, wind load, and snow load, and effectively transfer all loads to the pipeline bracket. At the same time, it must also meet the pipeline displacement caused by various loads to keep the entire pipeline system balanced and stable.

[0003] Overhead pipe supports can be divided into fixed supports and sliding supports according to the stress conditions and whether there is relative displacement between the pipe and the support. Under the premise of meeting the load effect, fixed supports require no relative displacement between the pipe and the support (usually achieved by welding), while sliding supports allow relative displacement between the pipe and the pipe support. The functional characteristics of sliding supports make the connection between the pipe and the support more complicated, which is mainly manifested in the following aspects: First, the relative displacement between the pipeline and the bracket needs to be limited. Too large or too small displacement will put the pipeline structure at risk and may cause damage to the pipeline expansion joint. Due to various external factors, the theoretical calculation of pipeline stress and displacement will deviate from the actual engineering installation. After the pipeline network is put into use, it is necessary to regularly calculate and monitor the pipeline stress and displacement status in real time when necessary. At present, there is no relevant device that can achieve this function.

[0004] Secondly, the displacement between the pipeline and the bracket is mostly achieved by relative sliding. For pipelines with larger diameters, due to the large vertical load, the sliding friction between the pipeline and the bracket will be very large. The friction will cause wear of the components and affect the safety of the pipeline itself. The connection device between the pipeline and the bracket is closely related to the normal service life of the pipeline and the cost of pipeline operation and maintenance.

[0005] The existing pipe seats mainly have the following deficiencies: 1. The pipe seats are welded in the factory with steel plates, steel sections, etc. according to the diameter of the installed pipes. The form and specifications of the pipe seats are fixed. After welding, they are transported to the site for installation and used in conjunction with the pipes. They are not prefabricated structures and lack flexibility in adaptability; 2. In order to meet the horizontal displacement of the pipeline, the pipe seat adopts the method of placing the steel pipe seat on the top beam of the bracket (a polytetrafluoroethylene plate is set at the bottom of the pipe seat), and the pipeline and the pipe seat slide on the top beam of the bracket, or the pipeline slides directly on the top of the pipe seat. Due to the large weight of the pipeline, the sliding friction generated is also large. Repeated friction can easily cause wear of the steel pipe wall or pipe seat components, affecting the service life of the pipeline; 3. The pipe seat does not have the real-time monitoring function of the stress state of the pipeline, and cannot monitor and warn the pipeline load and displacement in real time. When the support foundation settles, the support deforms, or the pipeline expansion device fails, safety accidents are prone to occur due to the lack of timely warning; 4. The pipe seat is usually not recyclable and reused. After the installation and construction is completed, maintenance and replacement are very difficult. Summary of the invention

[0006] The present invention provides an assembled pipeline support and monitoring device, which can withstand the vertical load and horizontal load generated by the pipeline and effectively transfer the load to the pipeline support. At the same time, it optimizes the existing sliding support and working mode, effectively reduces friction and realizes the force monitoring function.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is: An assembled pipeline support and monitoring device includes two end plates, the two end plates are U-shaped structures, an axle is installed at one end between the end plates, a roller disc is mounted on the axle, a spring is provided on the axle between the roller disc and the end plates, a pressure sensor is provided between the spring and the end plates, the middle position of the end plate is installed on the top surface of a pier or a bracket by fixing bolts, and the roller disc is in contact with the pipeline.

[0008] Preferably, a tie rod is provided at the other end between the end plates, and an adjusting screw is provided at the middle position of the tie rod.

[0009] Preferably, a gas monitor and a deformation monitor are installed at one end of the tie rod provided on the end plate.

[0010] Preferably, the roller disc is a cylindrical structure that is slender in the middle and thick at both ends.

[0011] Preferably, a bearing is provided between the roller disc and the shaft rod, a slot is provided on the shaft rod, a buckle is provided on the bearing, and the buckle on the bearing is connected to the shaft rod through the slot.

[0012] Preferably, the outer surface of the roller disc is provided with a rubber anti-slip layer.

[0013] The thermal benefits of the present invention are: (1) Different from the existing steel pipe seat, this support structure is assembled by multiple components and has the characteristics of a prefabricated structure with fewer components and more combinations. Prefabricated components of various specifications can be processed in the factory and assembled on site according to the actual installation needs of the pipeline. For example, this support structure can be combined with different roller discs according to the diameter of the installed pipeline to meet the installation requirements of pipelines with different diameters.

[0014] (2) This support structure uses a roller-disc combination component to replace the traditional steel pipe seat. When the pipeline is displaced along the pipeline laying direction, the roller disc rolls. 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 is displaced, but also reduces the wear on the pipe wall or components, thereby increasing the service life of the pipeline. When the pipeline is horizontally displaced along the vertical direction of the pipeline, the spring will contract and collect relevant load data through the pressure sensor.

[0015] (3) Through pressure sensors, deformation monitors and gas monitors, the vertical load, horizontal load, displacement and stress state of the pipeline can be collected, and early warnings can be issued for possible dangerous conditions such as foundation settlement, support deformation and pipeline cracking.

[0016] (4) The supporting facilities can be assembled on site and used immediately after installation. The components are small in size and light in weight, and can be inspected and maintained at any time. They can also be disassembled and recycled and then reassembled for use, which can effectively reduce construction costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments: like Figure 1-5 The assembled pipeline support and monitoring device shown in FIG. 1 includes two end plates 4, and the two end plates 4 are U-shaped structures, such as Figure 1 The U-shaped structure is long at one end and broken at the other end. An axle rod 2 is installed on one end between the two end plates 4 by bolts. A roller disc 1 is mounted on the axle rod 2. The roller disc 1 is a cylindrical structure that is slender in the middle and thick at both ends. The purpose is to stabilize the installed pipeline on the roller disc 1 to avoid derailment. A spring 3 is provided on the axle rod 2 between the roller disc 1 and the end plate 4. A pressure sensor 8 is provided between the spring 3 and the end plate 4, that is, one end of the spring 3 is connected to the roller disc 1, and the other end of the spring 3 is connected to the pressure sensor 8. When the pipeline 14 produces horizontal displacement in the vertical direction of the pipeline, the spring will contract and collect relevant load data through the pressure sensor 8. The middle position of the end plate 4 is installed on the top surface of the pier or the bracket by fixing bolts 7. The roller disc 1 is in contact with the pipeline 14, and the roller disc 1 is used to support the pipeline 14.

[0019] A tie rod 5 is provided at the other end between the end plates 4, and an adjusting screw 6 is provided in the middle position of the tie rod 5. The length of the tie rod 5 can be changed by adjusting the screw 6. After the tie rod 5 is adjusted to a suitable length, it cooperates with the shaft rod 2 to stabilize the supporting device.

[0020] A gas monitor 9 and a deformation monitor 10 are installed at one end of the tie rod 5 provided on the end plate 4. The gas monitor 9 monitors whether there is rupture and gas leakage in the nearby pipeline, and warns of abnormal pipeline conditions; the deformation monitor 10 determines whether the bracket is tilted and deformed by transmitting and receiving horizontal light beams, and can collect the displacement of the pipeline 14 and the stress state of the bracket, and warns of possible foundation settlement, bracket deformation, and pipeline cracks.

[0021] A bearing 12 is provided between the roller disc 1 and the shaft rod 2, a slot 11 is provided on the shaft rod 2, a buckle is provided on the bearing 12, the buckle on the bearing 12 is connected with the shaft rod 2 through the slot 11, and the installation using the bearing 12 can make the roller disc 1 rotate better on the shaft rod 2, and the installation of the pipe 14 is convenient; the outer surface of the roller disc 1 is provided with a rubber anti-skid layer 13, which plays an anti-skid protection role.

[0022] The support device converts the sliding friction between the pipe 14 and the bracket into rolling friction through the roller disc 1, which greatly reduces the adverse effect of friction on the support structure and optimizes the entire force system.

[0023] When in use, firstly, force calculation is performed according to the load, and 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 6, the fixing bolt 7 and other components are determined, and the processing is completed in the factory; the appropriate roller disc 1 is selected according to the diameter of the pipeline 14 and assembled; the end plate 4 is installed on the pipeline foundation or the top of the pipeline support through the fixing bolt 7, and the shaft rod 2 and the tie rod 5 are installed on the end plate 4 by bolts. When installing the shaft rod 2, the screw needs to pass through the roller disc 1 and the springs 3 on both sides thereof, and then the screws need to be fixed on both sides of the spring. Install the pressure sensor 8, and install the rod 2 on the end plates 4 on both sides; adjust the length of the tie rod 5 by adjusting the screw tube 6, and connect and fix the two tie rods 5 to the end plates 4. The tie rod 5 can stabilize the entire device; install the deformation monitor 9 and the gas monitor 10 at the end plates 4; tighten the fixing bolts 7 at the bottom of the end plates 4 to fix the device on the top surface of the pier or the bracket; place the pipe 14 on the roller disc 1 to complete the support; when dismantling the supporting structure, all components can be dismantled in the reverse order, and the components can be recycled.

[0024] The key technical points of the present invention are: 1. The roller disc 1 is a series of thin steel discs of different diameters. The discs of different diameters are combined to fit the bottom surface of the pipeline and provide good support for the pipeline. When the pipeline moves along the pipeline laying direction, the roller disc can rotate around the shaft. The roller disc can reduce the friction between the pipeline and the supporting structure, and measure the displacement of the pipeline according to the different roller disc positions and diameters.

[0025] When the pipeline is displaced along the pipeline laying direction and drives the roller disc to rotate, the rolling friction coefficient of the roller disc center bearing is approximately 0.001 to 0.005. Compared with the traditional sliding friction method, it effectively reduces the adverse effects of pipeline friction on pipeline support facilities.

[0026] Method for measuring the displacement of the pipeline by roller disc: (1) When the pipeline is displaced along the pipeline laying direction, the pipeline will drive the roller disc to rotate, and the pipeline displacement can be measured by the rotating roller disc. (L = α × r, L is the pipeline displacement, α is the center angle (radian), and r is the radius of the roller disc) (2) When the pipeline is displaced perpendicular to the pipeline laying direction, the pipeline and the roller disc squeeze the spring on the side, the spring will be compressed, and the pipeline displacement can be calculated from the force measured by the pressure sensor. (X=F / k, X is the pipeline displacement, F is the pressure measured by the pressure sensor, and k is the spring coefficient) 2. The edge of the roller disc is provided with a rubber anti-skid layer. Considering that the pipeline is usually in an open-air environment, the ambient temperature will have a greater impact on the rubber. The rubber anti-skid layer can be made of silicone rubber, which has the remarkable characteristics of high temperature stability and excellent low temperature performance.

[0027] 3. Pressure sensors are installed on the outside of the springs on both sides. When the springs are compressed, the pressure sensors can calculate the lateral load and the lateral displacement of the pipeline. The pressure sensors can also measure the vertical load of the pipeline through the force on the shaft, and analyze the state of the material transported by the pipeline.

[0028] 4. This device adopts a prefabricated structure. The prefabricated components can form a series of specifications and standards, providing conditions for the repeated use of components and giving full play to the characteristics of prefabricated components with few specifications and multiple combinations.
