Embodiment
below in conjunction with accompanying drawing, the utility model is described in further detail:
refer to shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, a kind of Bridge guardrail thrust measurement instrument its be made up of distance rod device, elevating table device 10, horizontal loading apparatus 7, bracket system 11.Described distance rod device is made up of universal platen 1, force snesor 2, displacement transducer 3, connecting link 4, curved boom 5, deck plate 8, acquisition controller 9.Described elevating table device 10 is made up of spacing screw mandrel 12, speed reducer for servo motor 13, line slideway auxiliary 14, cog belt and belt wheel 15, ball screw assembly, 16, limit switch 17, oscillating bearing 18.Described horizontal loading apparatus 7 is provided with draw-in groove 6, bulb 19.Described bracket system 11 is made up of clip 20, expansion link 21, v block 22, bearing 23.The elevating table device 10 of Bridge guardrail thrust measurement instrument deck plate 8 bottom provides power, drives the slide block of two cover line slideway auxiliaries 14 on base plate to move along a straight line, elevating table device 10 is moved up and down, meets the testing requirement of different Bridge guardrail, difference.Adopt line slideway auxiliary 14 to be exactly to reduce friction, thus simplify the internal structure of an organization, the accuracy of motion can be improved again simultaneously.Deck plate 8 top produces power by horizontal loading apparatus 7, and band deck plate 8 above two slide blocks overlapping line slideway auxiliaries 14 moves along a straight line, and connecting link 4 is seesawed, thus realizes the testing requirement to Bridge guardrail power and distortion.
refer to Fig. 2, Figure 3 shows that elevating table device structural representation and lifting table bottom plan view.This part is installed on upper and lower plates by each two pairs of line slideway auxiliaries 14 up and down, and under the driving of speed reducer for servo motor 13, power is 0.4kW servomotor.Rotated by cog belt and belt wheel 15, drive ball screw assembly, 16 to do rectilinear motion.Ball screw assembly, 16 right-hand member is provided with oscillating bearing 18, for adjusting screw and coupling shaft axle center deviation just.After test terminates, elevating table device 10 is returned to original state, and the weight on deck plate 8 top is placed on four spacing screw mandrels 12.
referring to Fig. 4 is horizontal loading apparatus structural representation.Be depicted as deck plate upper level charger 7.Guardrail load is detected with when being out of shape when machine does, ball screw assembly, 16 is to left movement, the slide block in straight direction guiding rail pair 14 is driven to move together with connecting link 4, by curved boom 5, power is passed on universal platen 1, after applying predetermined power, force snesor 2 and displacement transducer 3 will be passed in acquisition controller 9 by data line, obtain corresponding numerical value.
refer to Fig. 5, Figure 6 shows that universal platen and force snesor structural representation and connecting link and curved boom structural representation.Machine can be born 10kN pressure by one and not damage universal ball joint between universal platen 1 and force snesor 2, object be Bridge guardrail stressed after to have and topple over trend, this topple over trend certainly will between stress surface and force snesor 2, produce the angle that is greater than 90 °, this angle can cause force snesor 2 to be subject to side force, very easily damageability sensor 2.
curved boom 5 right-hand member locating sleeve has draw-in groove 6, draw-in groove 6 is corresponding with the through hole on connecting link 4, the through hole of connecting link 4 crosses a draw-in groove bolt, curved boom 5 up or down both direction all can fix curved boom 5, and form rock-steady structure for detecting test, curved boom 5 centre distance is 300mm, when curved boom 5 is placed downwards, can survey minimum altitude for-300mm, when curved boom 5 is upwards placed, can survey maximum height is 1000mm.Because this detector is positioned on car, the actual height that detects is with railway carriage height respective change.
refer to Fig. 7, Figure 8 shows that bracket system and connecting link structural representation, bracket system one-piece construction schematic diagram.When machine adjust to detect guardrail height time, just should bracket system 11 to be positioned in the middle part of connecting link 4 below ground, then expansion link 21 height is adjusted, on type v block 22 two bearings 23 are made just to touch connecting link 4 outside surface, locking hoop 20, make on the weight loaded carrier device 11 of whole connecting link 4, prevent from causing because connecting link 4 is overweight universal platen 1 to offset below tested point.Two bearings 23 also well can play the guide effect of connecting link 4.Bracket system 11 is made to be unlikely to overturning.
this Bridge guardrail thrust measurement instrument can carry motor vehicles, realizes field work, first entire machine is installed to the boot place of a picking-up vehicle, then adopts speed reducer for servo motor 13 to drive elevating table device 10 to load, realizes motion of retreating; Adopt ball screw assembly, 16 and line slideway auxiliary 14, realize guiding and reinforcement effect.After test terminates, elevating table device 10 should fall back initial position, upper table surface stablize be sitting in elevating table device 10 base four spacing screw mandrels 12 on.In addition, upper and lower two ball screw assembly, 16 ends are respectively equipped with four limit switches 17, play position limitation protection effect.
