Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further: a kind of flexible protection systems dynamic impact test platform, comprise the impact test block 3 for simulating falling rocks, for promoting and discharging the lifting appliance 2 and flexible protection systems test model 4 that impact test block 3, also comprise the counter force wall 1 for installing flexible protection systems test model 4, and provide recoil space for impact test and play the foundation ditch 5 of protective action; Described counter force wall 1 is vertically installed in the side of foundation ditch 5.
Lifting appliance 2 for completing the installation of flexible protection systems test model 4 and impacting the lifting of test block 3, and impacts test block 3 by automatic releasing device release after impact test block 3 reaches the height of test requirements document, makes its free-falling, completes impact test.According to test requirements document, lifting appliance 2 can be equipped with two suspension hooks, and the biggest lifting capacity of each suspension hook is respectively 5 tons, 25 tons, can meet the user demand of different impact energys, and suspension hook is 30m to the maximum height on ground, test site; The length of lifting appliance orbit must ensure that lifting appliance 2 can use in pilot region, and the distance between orbit is 24.5m.Lifting appliance 2 adopts straddle truck, and orbit adopts the rail 7 arranged outside ability foundation ditch 5.
Foundation ditch 5 and counter force wall 1 are the important component part in shock table, and both all adopt concrete structure and are linked to be an entirety.
Counter force wall 1 is for the installation of flexible protection systems test model 4, in order to satisfied different steel column 41 spacing (the steel column spacing of domestic conventional passive flexible protection systems is 10m), (domestic conventional passive flexible protection systems steel column height is 3m, 4m, 5m, 6m to different steel column 41 height, maximum height can reach 7m) the installation of passive flexible protection systems test model 4, the height of counter force wall 1 more than ground is 10.5m, length is 34m, and counter force wall 1 being provided with the equally distributed anchor hole running through counter force wall 1, anchor hole is spaced apart 500mm × 500mm.
Foundation ditch 5 must meet the deformation requirements of passive protection system under percussion, and play prevent impact test block drop into ground and hurt the effect of personnel and equipment, in addition foundation ditch 5 also for various test model installation, dismounting provide operation field.Foundation ditch 5 is of a size of 20m × 37m.Carry out deep-cutting of local to bottom the foundation ditch 5 often bearing rock-fall impact, form the protection hole 6 of inverted trapezoidal, to meet passive protection system under rock-fall impact effect, the needs of maximum distortion.
Impacting test block 3 is regular polyhedron, and it is the polyhedron that regular cube reams corner angle and obtain, and is highly 0.4m-2m, and weight is 0.25t-25t.For avoid impacting test block 3 with the impact process of guard system in destroy, impact test block external surface is formed by Plate Welding, inner configuration reinforcement, and concreting.For the ease of impact test block 3 rise winch to specified altitude assignment after can free-falling, special tripping gear can be adopted to impact test block 3 for discharging.Meanwhile, in the manufacturing process of impacting test block 3, can pre-buried crotch, for impacting lifting and the release of test block 3.
Described flexible protection systems test model 4 comprises protective screening 42 and pressure-reducing ring 44, and is vertically fixed on the steel column 41 of more than two or two of counter force wall 1 sustained height; Described protective screening 42 is fixed between two adjacent steel columns 41 by the supporting rope 45 being arranged on its surrounding; Described steel column 41 is connected with counter force wall 1 by anchor line 43 away from one end of counter force wall 1; Described pressure-reducing ring 44 is arranged on anchor line 43 and supporting rope 45.Steel column 41 is fixed on steel column pedestal 46 near one end of counter force wall 1, and steel column pedestal 46 and anchor line 43 are by being arranged on anchor pole in anchor hole and counter force wall 1 is fixed.
The operating principle of this test platform is: be installed on by flexible protection systems test model 4 on counter force wall 1, with lifting appliance 2, the impact test block 3 of constant weight is risen to certain height, utilize automatic releasing device that impact test block 3 is come off from suspension hook, impacting test block 3 movement of falling object is kinetic energy by potential energy converting and energy, with the passive flexible protection systems test model 4 of the energy impact designed.
