Embodiment
As shown in Figures 1 to 4, a kind of crane rail measure detection system, comprises PC control terminal 001, generating laser 100, dolly 200, laser pick-off screen 310, video-unit 320, controller 500 on car, distance measuring equipment 700, power supply 400.Dolly 200, laser pick-off screen 310, video-unit 320, controller 500 on car, distance measuring equipment 700, power supply 400 constitutes measurement dolly of the present invention.
As shown in Figure 3 and Figure 4, dolly 200 comprises base plate 210, two surperficial road wheels, four side guide wheels 230 and drive unit 240.
Base plate 210 is rectangular shape.Base plate 210 has hole (for sake of convenience in front and rear centre position, with dolly 200 close to the side of generating laser 100 for front portion, rear portion with the side away from generating laser), bearing seat 212 is provided with in both sides, hole, two surperficial road wheels are then positioned at above base plate, and be positioned at hole, and supported by the bearing in the bearing seat 212 of both sides, and the bottom of surperficial road wheel exceeds the lower surface of base plate 210 slightly, the center of gravity of dolly can be made so lower, thus improve stability when dolly is walked in orbit.In addition, for further improving carriage walking stability, also increase the counterweight 211 of orthohexagonal strip in the lower surface both sides of the edge of base plate 210, reduce further the center of gravity of dolly by increasing counterweight 211, the stability that dolly is walked in orbit improves further.
In two road wheels, that surperficial road wheel at rear portion is driving wheel 221, and that anterior surperficial road wheel is engaged wheel 222.
It is other that drive unit 240 is positioned at driving wheel 221, connected and composed by motor 241 and wheel box 242; Motor 241 is connected with driving wheel by wheel box 242, thus drives driving wheel 221.
It is two right that four side guide wheels 230 are divided into, and is located at the front and back position below base plate respectively, for clamping track.As shown in Fig. 4 composition graphs 5, particularly, two screw brackets 231 are all fixed with in the front and back end of base plate 210, these two screw brackets 231 have screw rod 232 by the bearings in it, this screw rod 232 part be positioned at outside screw bracket has the contrary screw thread in direction, and on screw rod, between two screw rods, cover has handle 233.To be positioned in the front and back end of base plate below screw rod both sides also symmetry have gathering sill 234, guide block 235 is provided with in this gathering sill 234, the top of guide block 235 has the threaded hole 236 coordinated with screw flight, middle part has " work " font groove 2341 of blocking gathering sill 234 edge and is positioned at the spike 237 of gathering sill 234 edge upper surface with bolt hole, is provided with and presses closer bolt 239 in the bolt hole of spike 237.Guide block 235 bottom, to downward-extension, as shown in Figure 6, is provided with wheel support 238 inside bottom, and side guide wheel 230 is arranged on wheel support 238, is wherein also provided with spring 2351 between the wheel support 238 of side and guide block 235 bottom.Adopt this structure, when unclamp press closer bolt 239, screw rod 232 can be rotated by rotary handle 233, under gathering sill 234 leads, regulate the distance between two guide blocks, and then regulate the distance of two side guide wheels 230, to adapt to different track width.After spacing between the guide wheel of side is adjusted, pressing closer bolt 239 by screwing, allowing pressing closer the edge that bolt 239 presses closer gathering sill guide block 235 can be allowed to be fixed on base plate.Spring 2351 makes the guide wheel of the side of side have elasticity, if run into the gap of rail joint, can not be stuck, improve the property passed through of dolly.
For another example, shown in Fig. 3, Fig. 4 composition graphs 1, laser pick-off screen 310, video-unit 320, power supply 400, on car, controller 500, distance measuring equipment 700 are all fixed on base plate 210.Wherein, laser pick-off screen 310 is fixed on a cabinet 250 in the middle part of dolly, and towards generating laser 100, the laser beam that its surface and laser generator 100 send is perpendicular.And controller 500 is positioned at the bottom of cabinet 250 on car, video-unit 320 is positioned on the rear end face of cabinet 250, the camera 321 of video-unit 320 is positioned at cabinet 250, the afterbody of video-unit 320 exposes outside cabinet 250, it has wireless transport module (such as wifi module).Like this, be just in a darker space between video-unit 320 and laser pick-off screen 310, laser imaging is effective.On car, controller 500 is a single-chip microcomputer, and it has bluetooth module.
In order to be convenient to rotate can receive the laser beam of different directions, described casing 250 is positioned on the rotating disk 260 of a band angle index, rotating disk has locking mechanism, for fixing after the laser pick-off screen anglec of rotation.
Distance measuring equipment 700 is grating encoder in the present embodiment, is arranged on base plate 210, is positioned at engaged wheel other 222 and is connected with engaged wheel 222, being obtained the travel distance of dolly by the mode of ranging pulse.
In the present invention, laser pick-off screen 310 adopts PVC board to make, and its surface sand-blasting process, the inside has phosphor powder layer.Adopt the laser pick-off of such structure to shield, imaging effect is good, and during with generating laser distance, hot spot can not spread, and apart from time near, and laser penetration light can not be too strong and burn out camera.
In the present embodiment 100, laser generator 100 can turn to and regulate height emission angle.Generating laser 100 preferably sends green laser, the light 200m that it sends, and spot diameter is no more than 20mm, and generating laser 100 is by adjustment, and its horizontal accuracy is that 100m error is less than 2mm.
Be exactly more than crane rail measure detection system of the present invention, its working method is:
And dolly also to be installed fixing for generating laser 100 in orbit in orbit, control dolly by PC control terminal 001 and walk in orbit, travel distance in orbit when obtaining dolly by distance measuring equipment 700.The illumination allowing generating laser 100 send is mapped on laser pick-off screen 301, and laser forms hot spot on laser pick-off screen 301.Dolly 210 is walked in orbit, video-unit 320 can carry out an image acquisition every about 0.18m, and image transmitting is processed to PC control terminal 001, PC control terminal 001 can extract the centre coordinate of hot spot, and draw out curve map, as shown in Figure 8, diverse location height tolerance and the horizontal departure of track so just can be detected, if measure left and right two guide rails, span difference and the difference of height of two tracks just can also be calculated further.
In sum, the present invention has conveniently, carries out measuring the advantage detected to the crane runway of high-altitude and ground erection efficiently.
