Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic tool testing and detection, and relates to a comprehensive test bench suitable for hydraulic maintenance tools in power stations. Background Art

[0002] Turbine operation is an important aspect of the operation of the turbine generator set in a hydropower station. In order to ensure that the unit can produce electricity safely, reliably and stably, all power equipment participating in the production of electricity must be regularly inspected and maintained. Therefore, the operation, inspection and maintenance of the turbine operation during the inspection and maintenance work are also very important links. In the inspection and maintenance work, due to the large size and heavy weight of the parts of the turbine unit, it is necessary to use hydraulic tools to carry out the work. Among them, hydraulic bolt tensioners and hydraulic torque wrenches are the most commonly used hydraulic tools in the inspection and maintenance work. However, as the use time and frequency of use increase, the use conditions change. Due to the wear of the internal structure and the aging of the sealing material, the hydraulic tools will inevitably degrade in performance and are prone to precision errors. It is necessary to regularly perform performance testing and precision calibration on the hydraulic tools to ensure that the working parameters and output data accuracy of the hydraulic tools are effectively controlled. Once an unpredictable fault occurs, it will lead to maintenance accidents, reduce operating efficiency, slow down the maintenance cycle, and seriously cause safety accidents.

[0003] The common test benches at present are only specialized for the inspection and testing of a certain type of hydraulic tools. In addition, the specifications of the inspection tools are relatively simple, and the specifications and performance parameters covered are very limited.

[0004] Taking the hydraulic bolt tensioner test bench as an example, the current test bench can only perform inspection tests on a single model of tensioner, and the inspection parameters are single. It is impossible to synchronously measure the stretching length of the tested bolt under the corresponding tensile force, and it is impossible to accurately detect the deformation of the tensioner body. At the same time, the internal leakage of the tensioner itself cannot be detected.

[0005] Taking the hydraulic torque wrench test bench as an example, currently most of them can only test wrenches with similar bolt and nut specifications, and the torque value detection capability range is too small, and the actual torque value often exceeds the detection range. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a comprehensive test bench and method suitable for hydraulic maintenance tools in power stations, which can be used for performance detection and calibration of hydraulic tools such as sealing, torque, pressure and preload. It can be specifically aimed at performance detection and testing of commonly used maintenance tools in hydropower stations, including hydraulic bolt tensioners and hydraulic torque wrenches. Considering the working environment and actual working conditions, a modular design concept is implemented to achieve high parameter measurement accuracy, large coverage and comprehensive detection data.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is: a comprehensive test bench for hydraulic maintenance tools in power stations, which includes a hydraulic bolt tensioner test bench and a hydraulic torque wrench test bench electrically connected to a central data processing station; the hydraulic bolt tensioner test bench includes a tensioner test working panel, and a magnetic support is respectively arranged on the upper and lower sides of the tensioner test working panel and is symmetrical to each other, and two contact displacement sensors are respectively connected to the two magnetic supports; bolt tensioners and preload sensors are respectively arranged on both sides of the through hole of the tensioner test working panel; the torque sensor of the hydraulic torque wrench test bench is connected to the torque wrench test working panel and the mounting sleeve through bolts.

[0008] The washers, round nuts, bolt tensioners and preload sensors of the hydraulic bolt tensioner test bench are fixed on the tensioner test working panel, and the contact displacement sensors are clamped by magnetic supports and placed on the upper and lower surfaces of the tensioner test working panel respectively.

[0009] The washers, round nuts and bolt tensioners of the hydraulic bolt tensioner test bench fix the tested bolts on the tensioner test working panel.

[0010] The contact displacement sensor contacts the upper and lower sections of the bolt to be measured, thereby measuring the tensile strength of the bolt.

[0011] The tensioner test working panel is replaceable; the hydraulic bolt tensioner test bench and the hydraulic torque wrench test bench adopt a modular structure split design.

[0012] A reaction device is provided on the torque wrench test working panel of the hydraulic torque wrench test bench, and the transition head is connected to the sensor connection flange through a transition spline and is located in the area enclosed by the reaction device.

[0013] The reaction force device is three flat plates, which are respectively arranged on three edges of the torque wrench test working panel, and each flat plate is provided with a stiffening plate.

[0014] The transition head plays a role in the torque transmission conversion of the hydraulic torque wrench.

[0015] The transition heads are of multiple different specifications and are replaceable. By replacing the transition heads of different specifications, a test covering torque wrenches of multiple specifications can be formed.

[0016] The test method applicable to the comprehensive test bench for hydraulic maintenance tools of power stations as described above comprises the following steps: S1, bolt tensioner performance test, connect the bolt tensioner and the bolt to be tested and place them on the tensioner test working panel, then assemble the magnetic support and the contact displacement sensor and adsorb them to the upper and lower surfaces of the tensioner test working panel, then adjust the magnetic support according to the actual space requirements so that the contact displacement sensor can contact the upper and lower end surfaces of the bolt to be tested, after the arrangement is completed, connect the oil pipe of the bolt tensioner, start the hydraulic pump of the bolt tensioner, and the displacement of the upper and lower end surfaces of the bolt to be tested is detected by the contact displacement sensor, and is displayed and recorded in real time on the central data processing station; start the pressure sensor and preload sensor of the bolt tensioner to synchronously detect the system pressure and the tension of the bolt to be tested, that is, the preload, and form a chart output on the data panel of the central data processing station; S2, bolt tensioner deformation and internal leakage detection. When detecting the bolt tensioner deformation, it is only necessary to adjust the contact displacement sensor to contact the surface of the cylinder of the bolt tensioner to measure the bolt tensioner deformation when it is working. When the internal leakage of the bolt tensioner needs to be detected, it is only necessary to select the internal leakage measurement option on the operation panel. After the hydraulic pump of the bolt tensioner is pressurized, the program will automatically calculate. By bringing the pressure difference before and after a period of time into the set formula for calculation, the internal leakage value can be directly displayed on the program panel of the central data processing station. S3, hydraulic torque wrench performance test, first of all, it is necessary to determine the maximum torque value of the tested wrench, and select the corresponding working position on the torque wrench test working panel; then determine the square drive size of the wrench and select the corresponding transition head; after the wrench is placed, the wrench force arm leans against the reaction device on the torque wrench test working panel, the oil pipe of the hydraulic pump is connected, and the electric hydraulic pump is started, and the actual torque value output by the hydraulic wrench under the current pressure can be measured, and a chart output is formed on the data panel of the central data processing station; in this step, the transition head can not only convert the inner hole square drive size, but its outer ring is designed to be a hexagonal square shape, which can also be used for the conversion of the central control wrench; therefore, if the hydraulic wrench is a hollow wrench, the size can also be converted through different transition heads, and the configuration is flexible; S4, central data acquisition and calculation, the central data processing station integrates PLC data acquisition module, USB output module, terminal display screen and data operation software. Each detection data is first collected by various sensors, and then converted into corresponding analog signals by the signal conversion module and output to the PLC data acquisition module in the central data processing station; the collected data is calculated by PLC and the calculation formula embedded in the data operation software, converted into the data and charts we need, and then displayed in real time on the terminal display screen. The data operation software has a real-time record and save function, and finally the data can be saved and sent externally through the USB output module.

[0017] The main beneficial effects of the present invention are: The modular split design reduces the weight of the equipment unit, facilitates movement and transportation, and makes the overall assembly and transportation of the equipment more convenient, solving the problem of inconvenient installation, storage and transportation of comprehensive equipment.

[0018] The table top of the tensioner test adopts a replaceable design. According to the specifications of different tensioners and bolts, the corresponding work table and special tooling can be used to test bolts in the range of M20-M200. The preload measurement range is 200-5000kN. At the same time, the elongation of the tested bolt under the corresponding tensile force can be measured synchronously, which solves the problems of few compatible specifications of the bolt tensioner test bench and small preload measurement range, and innovatively adds the synchronous measurement of the bolt elongation.

[0019] The workbench for hydraulic torque wrench testing adopts a double-working position design and innovatively designs a special tooling for connecting the torque wrench and the sensor, so that one workbench can fully cover the nut specifications of S27-S240 and the torque value measurement range of 300-150000N·m, solving the problems that the current general wrench test bench can only test a single specification wrench and has a small torque range.

[0020] The central data processing station uses an intelligent human-computer interaction interface, and integrates data acquisition and operation panels into a control console. The measured data is transmitted to a unified integrated display terminal through a communication cable. The tested data is collected and recorded in a computer, and can also be plotted in real time and support external output. This solves the problems of conventional test benches collecting single data and being unable to calculate and plot corresponding charts in real time. BRIEF DESCRIPTION OF THE DRAWINGS
