It fixes in the fixing notch of tooth plate 608, makes angle steel that posture be kept not change, then driving device 3 drives boom 2 to roller
Road hoistable platform movement, until roller-lifting platform rises to be put when overturning electromagnet 6 is located above roller-way convenient for electromagnet 6
The position of lower angle steel, at this point, electromagnet 6 puts down angle steel.In the motion process of boom, since wrist multi link level keeps filling
It sets and forms two parallel four-bar linkages, and the original state of wrist 7 is horizontality, therefore, in whole service process
In, wrist 7 remains horizontal.
Then carry out reversed code steel, need first stacking profile by grouping lifting platform be promoted to it is higher connect steel position, then drive
Motivation structure 302 acts, and drives boom forward swing to steel position is connect by connecting lever 303, axis 305, rocking bar 303 and connecting rod 301, then electricity
Magnet retractable driving device 702 is stretched out, and driving torsion shaft 701 rotates, and is driven overturning electromagnet 6 to rotate by reduction gearbox, is made magnetic
Angle steel is drawn in the horizontal direction of pole.Since angle steel is in code, it is inWhen angle steel radix-minus-one complement, it is good to be superimposed upon previous code for shape
Angle steel on, be inShape, code, that is, angle steel is opening down, and radix-minus-one complement, that is, angle steel is opening up.Work as angle steel
When code, since the closed angle end for being angle steel is single line contact, contact area very little, it is easy in electromagnet with electromagnet 6 upward
Rollover is generated on 6, so guiding tooth plate 608 must be arranged on electromagnet, the angle steel of code is oriented to.But subsequent
Radix-minus-one complement during, guiding tooth plate 608 can and code angle steel interfere, it is therefore desirable to make angle steel edge and horizontal face contact,
Therefore it needs to drive tooth plate 608 to move by tooth plate driving mechanism 607 before drawing angle steel, makes the edge and tooth plate 608 of angle steel
Straight portion alignment.Then grouping lifting platform moves downward, and angle steel is drawn on electromagnet 6, and lifting platform to be grouped, which leaves, to be turned over
After turning region, electromagnet telescoping drive mechanism 702 is retracted, and overturning electromagnet 6 reversely rotates 180 °；Then driving device 302 is driven
Dynamic connecting lever 303 moves, and drives boom 2 to be rocked to reversed code steel position by axis 305, rocking bar 303 and connecting rod 301, arrives to boom
Behind position, 6 power loss of electromagnet is overturn, is fallen on stacking lifting platform under steel.
In the motion process of boom, the pressure in the gas bag 510 of the present embodiment should meet: one, balance cylinder 501 pushes away
The trimming moment that power generates is slightly larger than the maximum load moment of resistance generated of being self-possessed during swing arm motion, and two, gas bag 510 is entire
Pressure is basically unchanged during driving.Under the conditions of above-mentioned two, the effect of no drive link, swing arm will be in balance cylinder 501
Thrust lower swing to foremost position, therefore the stress of drive link becomes tension from original compression, avoids the occurrence of compression bar
Unstable phenomenon；After 2 forward swing of swing arm connects steel, the weight of steel is increased, becoming larger for loading moment is conducive to swing arm backswing, and driving connects
The pulling force of bar also reduces therewith；In 2 action process of swing arm, balance cylinder 501 is constantly in thrust rating, and driving pull rod is always
In tension state, connecting component stress does not commutate, so that eliminating the gap of hinged place influences.Be conducive to boom swinging
Precision in the process improves.
In the motion process of boom, positioned by movement latter end of the positioning device to boom, process is as follows:
During forward swing, boom 2 starts the period by 302 full-speed operation of driving device in movement, and driving boom 2 quickly moves, boom 2
When by upper trigger mechanism, into movement latter end, controller obtains 2 current location of boom by positioning device, and controls driving
Device 302 drives boom movement, and when boom is when being closely located to predetermined position, controller controls compensation device driving boom 2 and transports
Dynamic, the kinematic accuracy of compensation device is high, and boom can be made accurately to stop at predetermined position in this way, the process put after boom 2 with
The process of forward swing is similar.In this way, the initial segment of movement does not need to calculate, the operand of controller can be greatly reduced.And at end
Section, range measurement mechanism measure the position of boom, and error is very small, then drive boom movement by high-precision compensation device,
Boom can be made accurately to stop at predetermined position.
Embodiment 6
Driving device is changed to telescoping mechanism by the present embodiment, and the boom is connect with 201 anti-rotation of the first articulated shaft,
The both ends of the telescoping mechanism are hinged with the boom and rack respectively.
In the present embodiment, boom is connect with 201 anti-rotation of the first articulated shaft, boom is then driven by telescoping mechanism
2 are moved, and are connect at this time due to boom 2 with 201 anti-rotation of the first articulated shaft, boom 2 can also move.This reality
Boom 2 will be directly driven and be moved using telescoping mechanism by applying example, without transmission, can reduce the energy consumption in transmission process,
Improve energy conversion efficiency.
On the basis of the above embodiments, the mobile ranging localization mechanism can also be replaced with fixed ranging localization machine
Structure, as shown in figure 11, the fixed ranging localization mechanism includes the positioning plate 215 hinged with boom or crossbeam bottom, for protecting
Hold the range measurement mechanism that the vertical vertical holding mechanism of the positioning plate 215 and the corresponding positioning plate 215 are arranged；It is described
