Description
Technical field
This utility model relates to a kind of travel mechanism, especially concrete impact-resistant mill testing system transverse-moving mechanism.
Background technology
At concrete for hydraulic structure engineering field, it is necessary to concrete abrasion-resistant performance is tested, namely need concrete surface is tested by the phase resistance of flow at high speed Mediawear, for evaluating the relative resistant abrasion performance of concrete surface.
Concrete corrosion wear speed is to rely on the state variable of time, owing to interacting with environment, sediment charge, composition and motion change in current, under the state all random in one, changeable such as the model of action between sediment laden flow and material, material is produced ablation destruction, therefore, the material of scour and abrasion resistant concrete and the select permeability of match ratio just become extremely complex, and the mode often only by Experimental Comparison determines the performance of concrete material impact-resisting wear-resisting under different situations.
Concrete material is that consumption is maximum up to now, purposes building structural materials the most widely.The resistance to impact and abrasion of the concrete material of the structure positions such as spillwag chute in hydraulic structure, draft tube, flood discharging tunnel, scouring sluice is the important technology index evaluating these position concrete structure durabilities.
China promulgated concrete for hydraulic structure test method in 1962, wherein recommended the ring method that agent on crack resistance of concrete is tested containing sand current scour；Then pass through to revise for the first time and promulgated " concrete for hydraulic structure testing regulations " SD105-82 in nineteen eighty-two, after 1996 carry out second time revision, new " concrete for hydraulic structure testing regulations " SL352-2006 has been promulgated in 2006, it is developed at present, the evaluation of concrete impact-resistant anti-wear performance is generalized to two methods, it is that agent on crack resistance of concrete tests (ring method) and concrete anti-abrasion test (under water steel ball method) containing sand current scour respectively, to adapt to scour and abrasion resistant concrete in different current scour speed, the different resistance to impact and abrasion evaluations destroyed under media type effect.
At present, utilize the concrete that steel ball method under water carries out concrete impact-resistant abrasion test to rush grinding machine structure (the HKS-II type concrete anti-abrasion tester such as Nanjing Hydraulic Research Institute's instrument plant produced) and include being fixed on extenal fixation frame and the guide rail on ground；Frame is stretched in guide rail one end, and the other end stretches out frame.Guide rail is provided with interior moving frame, and the bottom of interior moving frame is connected on guide rail by roller.There is columnar test cylinder (steel cylinder) at interior moving frame top by Flange joint, and test cylinder bottom is connected to water out adapter, and water out adapter extends downwardly into interior moving frame and water out adapter is provided with outlet valve；Water out adapter is connected to drain pipe.Test cylinder top is provided with cover, and cover center is provided with for the central shaft hole through shaft.Extenal fixation frame top is higher than test cylinder top；Extenal fixation frame is provided with motor, and motor shaft stretches out downward vertically and connects shaft by clamping connecting shaft structure, and shaft passes downwardly through central shaft hole and stretches into test cylinder and be connected to stirring paddle.
During test, cylindrical concrete sample (diameter 300mm ± 2mm, height 100mm ± 1mm) is put into test cylinder, and needs to put into some steel balls according to test, then water filling in cylinder；First by shaft from bottom to top through cover central shaft hole, interior moving frame is pushed extenal fixation frame, then manually shaft and motor shaft are connected together.Start motor, motor drives stirring slurry to rotate with the speed of about 1200r/min by shaft, makes to be formed in cylinder high-velocity flow, and steel ball is also with current high speed rotating, thus concrete sample is washed away by simulated flow and waterborne material, the resistance to impact and abrasion of test concrete sample.
Existing utilization steel ball method under water carries out the concrete of concrete impact-resistant abrasion test and rushes mill apparatus, every time before test, need the artificial outside that interior moving frame moves on to extenal fixation frame that concrete sample could be put into the cylinder of test cylinder, then need again manually to move in extenal fixation frame by interior moving frame, test could be started.Off-test needs again artificial by interior moving frame removal extenal fixation frame.Interior moving frame and the concrete carried thereof rush mill testing system cylinder weight very greatly, manually carry out travelling backwards labor intensity very big, inefficient.
