Description
Technical field
The present invention relates to a kind of detection platform, especially relate to a kind of concurrent movable test platform.
Background technology
Electric pole is one of supporting construction the most frequently used in built on stilts electric line.But its long-term work is outside, by acting on of the erosion of water in soil environment and various external load and internal stress, easily produce crack.The existence in crack will increase the weight of degree and the degree of steel bar corrosion that in running, electric pole is corroded by harmful substance, reduce the bearing capacity of electric pole, thus reduce the durability of electric pole, increase the operation risk buried depth section fracture of electrical network, along with the infrastructure such as electric power, railway input is strengthened by country year by year, and the infrastructure of China's electricity consumption is the most progressively upgraded now, and a lot of extra-high voltages, coming into operation of supertension line have driven the upgrading process of China's entirety circuit.The most just improve the quality to electric pole (intensity, crack resistance, amount of deflection etc.) requirement during upgrading, the raising of prescription just allow electric pole inspection become the most frequently change.The detection platform of conventional electric pole is as follows:
As it is shown in figure 1, vertical drop-down detection platform (calling platform one in the following text): include being made up of pedestal 1, charger and deadweight cancellation element.Pedestal armored concrete pours, and for ease of observing crack, the method using cantilever to be further applied load straight down is tested.Operating process is: first, and the one end (calling tail end in the following text) being embedded in soil by electric pole is fixed on pedestal 1, first undertakes the weight of whole electric pole with jack 1；Then, progressively removing jack top power, the value that ergometer 1 reduces is equivalent to the deadweight gravity at electric pole position of centre of gravity, and the gravity of center of gravity is converted the load of tail end；Finally, after the power of the jack of deadweight cancellation element is all removed, then with jack 2 22 multistage loadings of tail end, the numerical value of record ergometer 2 32, calculate electric pole and convert tail end load: be deadweight and jack 2 22 loading force sum.In the process by the amount of deflection of electric pole, flexibility and body of rod Size of Crack.
As shown in Figure 2, horizontal layback detection platform (calls platform two in the following text): similar with the most drop-down principle, electric pole tail end is fixed on pedestal 1 side by high-strength bolt, support base 4 is set in the lower section of the electric pole body of rod, charger is fixed on pedestal 5, by charger (Lever Blocks), the tail end of electric pole is applied the pulling force of horizontal direction, detects.
In above two detection platform, platform one is that electric pole directly prevents pedestal 1 upper surface, from the point of view of comparing the side that platform two needs to be bolted on electric pole pedestal 1, implement more convenient, and platform two supports base 4 when loading electric pole and can not withdraw, and support base 4 and need to follow electric pole and move horizontally, the structure of detection can be brought error by the frictional force of moving process, but in above two detection platform: the pedestal volume of platform one is the most not easily shifted, the pedestal of platform two cannot move, need to move electric pole to base position and test, to site requirements, relatively greatly and line of transference bar is wasted time and energy, current eurypalynous electric pole sampling inspection work is made troubles.
