Description
Technical field
The present invention relates to a kind of displacement device, especially a kind of displacement device for large component, for example, crawler crane track beam assembling displacement device.
Background technology
Positioner refers to change the special purpose machinery of workpiece origin-location, is about to workpiece turning to the position that needs, and the convenient operation person welds, assembles or operates.Positioner is again tipper sometimes.
The track beam positioner mainly contains two kinds of patterns at present, and a kind of is L shaped positioner, and this positioner mainly is comprised of base 82, gusset support 84, driving oil cylinder 83, Hydraulic Station etc., track beam 81 is overturn, as shown in Figure 8; Another kind is the chain type positioner, and this positioner mainly is comprised of several parts such as motor reducer 91, sprocket wheel 93, tipper main frame 94, upset chains 92, as shown in Fig. 9 (1), 9 (2) and 9 (3).
81 needs of the first pattern track beam are put in the L-type positioner, and the side is close to gusset support 84 and gets final product, and need not clamping, but needed for two steps during upset, each step overturns 90 °, and each step all needs the driving lifting once, the driving frequency of usage is higher, takies running time long; In addition, on track beam, planar cloth is provided with four link-supporting plates, wherein two higher, and spacing is less, and the end face that these two link-supporting plates consist of can contact with gusset support 84 as weight-bearing surface, due to track beam profile reason, causes in switching process that load-bearing is unstable, track beam is easily tumbled, the unexpected overturning phenomenon of track beam very easily occurs, produce potential safety hazard.
As long as the second pattern track beam is placed on chain, do not need clamping.But there is following shortcoming in it:
(1) because the upset chain is flexible, track beam on the upset chain in switching process the center of gravity of track beam in continuous variation, so track beam rock on the upset chain very large, impulsive force is very large; Need track beam to maintain static during assembling, that is to say, could assemble when only having track beam motionless on the upset chain, and flexible chain track beam when assembling easily rocks, and can only overturn, and can't realize assembling, can not realize that more multiple-shaft tightening machine is used in conjunction with; Track beam is by rocking transfixion, and this needs a period of time; And when assembling the operator be not intended to encounter track beam or external force is encountered track beam, track beam is shaken again move up, therefore this displacement mode shortcoming is that track beam easily rocks on chain and is unfavorable for assembling, and operating efficiency is low.
(2) chain is when motion, and heavier because of the track beam own wt, between track beam and chain, easily generation slip, cause track beam to be scratched, to collide with, and has a strong impact on product quality.
(3) on track beam, thrust wheel is housed, thrust wheel is circular-arc, faces mutually the thrust wheel spacing less, and the spacing between each thrust wheel is all different, rocks greatlyr when overturning simultaneously, causes between chain and thrust wheel and produces inconsistent phenomenon, have a strong impact on upset efficient, produce potential safety hazard.
Can say, the main driving upset operating type that adopts of track beam upset at present, technical merit falls behind, and there are potential safety hazard in personnel and driving.There is impact in this upset mode, easily causes track beam to collide with, scrape and injure distortion, stays hidden danger of quality to later process.Along with output increases year by year, and it is longer to use driving upset displacement to take running time, causes driving can not satisfy normal lifting operation amount, the lifting of restriction overall throughput.

Electrical system is Purchased Item, comprises the lead limit switch of switch board, motor, the upset of control positioner.Motor is power source, and for whole system provides power, lead limit switch is controlled positioner upset stroke, prevents the positioner upset excessively, causes contingency.
Every crawler crane includes left track beam and right-hand track chiain beam, can be with two cylinder tensioners of two cylinders of right twin columns assembly 5 and left twin columns assembly 6 by twin columns tensioner screw mandrel 7 and track beam is fixed on turning beam 4.Because left track beam, right-hand track chiain beam profile are opposite, so the displacement form is opposite, now carry out the elaboration (as shown in Figure 4) of scheme as an example of the right-hand track chiain beam example.
In Fig. 4, the workpiece of dotted line is right-hand track chiain beam 31, is fixed in queen post crawler crane track beam assembling positioner.The right-hand track chiain beam is provided with one group of thrust wheel 32, and each thrust wheel is fixing by a plurality of bolts (for example 4 bolts).The top is vertical multi-shaft tightening machine (for example vertical four axle tightening machine 41), and tightening machine 41 is suspended on cantilever 43 by suspension apparatus 42, and cable 44 is connected system control cabinet 45 with tightening machine 41.Tightening machine 41 is used for tightening the protrusion on track beam 31, and described protrusion is thrust wheel 32, and these four rectangular array distribution of bolt, can disposablely be tightened simultaneously by four axle tightening machine.
The concrete operations flow process is:
Operate the horizontal adjusting screw 8 of twin columns, adjust the relative position of two groups of twin columns assemblies, satisfy the demand of different product.Operation twin columns tensioner screw mandrel 7 to minimum, is connected with track beam two twin columns hypotelorisms in every group of twin columns assembly with twin columns, operation twin columns tensioner screw mandrel 7 is with twin columns tensioner, fixedly track beam.Operate vertical four axle tightening machine and tighten bolt on thrust wheel, fixing thrust wheel, tighten complete after, with 180 ° of positioner displacements (specifically refineing to the concrete parts of operation positioner), then operate twin columns tensioner screw mandrel 7, twin columns are unclamped, hang away track beam, end of operation.
The positioner principle: this tipper is mainly to adopt mechanical transmission.
Track beam divides two kinds, left track beam and right-hand track chiain beam, profile has larger difference, therefore the left and right track beam is also different from tipper closure, when left track beam is installed, two groups of twin columns of positioner is turn to illustrate the top view position, be connected with two square holes on track beam again, operation 7 (leading screws) reach the fixedly purpose of track beam with two groups of twin columns tensioners, then operate positioner and are rotated counterclockwise 180 °, until encounter lead limit switch, positioner stops the rotation.
The right-hand track chiain beam is opposite with the operation of left track beam, at track beam with before positioner is connected, need to be with positioner Rotate 180 in top view ° (be left track beam overturn the position of positioner afterwards), all the other operate identical with above-mentioned left track beam.
In addition, as shown in Figure 7, described rotary system also can comprise hydraulic unit driver 74, roller is arranged on turning rolls 75, and described hydraulic unit driver 74 drives roller and rotates, and roller is given upset gear ring 71 with power transmission, the inner fixedly track beam 31 of upset gear ring 71, thus track beam is rotated.
Described rotary system also can comprise reel and steel wire rope, pulls rollover stand to overturn by reel and steel wire rope combination.
