Description
Technical field
The utility model 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, such as Fig. 9 (1), 9(2) and 9(3) shown in.
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, planar cloth is provided with four link-supporting plates 85 on the track beam, 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, owing 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 the 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 the switching process center of gravity of track beam in continuous variation, so track beam the upset chain rock 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 run into track beam or external force is run into 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, easily generation slip causes track beam to be scratched, to collide with between track beam and the chain, has a strong impact on product quality.
(3) on the 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 the 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 at present track beam upset, 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.
