Description
Technical field
The utility model relates to a kind of displacement device, especially a kind of displacement device that is used for large component, for example, crawler crane crawler belt beam assembling displacement device.
Background technology
Positioner is meant the special purpose machinery that can change the workpiece origin-location, is about to the position that workpiece turn to be needed, and is convenient to the operator and welds, assembles or operate.Positioner is tipper sometimes again.
Crawler belt beam positioner mainly contains two kinds of patterns at present, and a kind of is L shaped positioner, and this positioner mainly is made up of base 82, gusset support 84, driving oil cylinder 83, Hydraulic Station etc., and crawler belt beam 81 is overturn, and is as shown in Figure 8; Another kind is the chain type positioner, and this positioner mainly is made up of several parts such as motor reducer 91, sprocket wheel 93, tipper main frame 94, upset chains 92, like Fig. 9 (1), shown in 9 (2) and 9 (3).
81 needs of first kind of pattern crawler belt 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 need be driven a vehicle lifting once; The driving frequency of usage is higher, and it is long to take running time; In addition, planar cloth is provided with four link-supporting plates on the crawler belt beam, wherein two higher; And spacing is less; And the end face that these two link-supporting plates constitute can contact with gusset support 84 as weight-bearing surface, owing to crawler belt beam profile reason, causes in switching process load-bearing instability, crawler belt beam to be tumbled easily; The unexpected overturning phenomenon of crawler belt beam very easily occurs, produce potential safety hazard.
As long as second kind of pattern crawler belt beam is placed on the chain, do not need clamping.But there is following shortcoming in it:
(1) because the upset chain is flexible, the crawler belt beam on the upset chain in the switching process center of gravity of crawler belt beam in continuous variation, so the crawler belt beam on the upset chain, rock very big, impulsive force is very big; Need the crawler belt beam fixed during assembling, that is to say, have only the crawler belt beam when upset is motionless on the chain, could assemble, and flexible chain crawler belt beam easy shaking when assembling can only be overturn, and can't realize assembling, and can not realize that more multiple-shaft tightening machine is used; The crawler belt beam is by rocking transfixion, and this needs a period of time; And when assembling the operator be not intended to run into the crawler belt beam or external force is run into the crawler belt beam, the crawler belt beam is rocked once more, therefore this displacement mode shortcoming is that crawler belt beam easy shaking on chain is unfavorable for assembling, and operating efficiency is low.
(2) chain because of crawler belt beam own wt is heavier, is prone between crawler belt beam and the chain produce slide when motion, causes the crawler belt beam to be scratched, to collide with, and has a strong impact on product quality.
(3) on the crawler belt beam thrust wheel is housed, thrust wheel is circular-arc, and it is less to face the thrust wheel spacing mutually; And the spacing between each thrust wheel is all different, rocks greatlyyer 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.
We can say, the main driving upset operating type that adopts of crawler belt 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, causes the crawler belt beam to collide with, scrape and injure distortion easily, 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.

Every crawler crane includes left crawler belt beam and right-hand track chiain beam, can two cylinder tensioners of two cylinders of right twin columns assembly 5 and left twin columns assembly 6 be fixed on the crawler belt beam on the upset crossbeam 4 through twin columns tensioner screw mandrel 7.Because of left crawler belt beam, right-hand track chiain beam profile are opposite, so the displacement form is opposite, existing is the elaboration (as shown in Figure 4) that example is carried out scheme with the right-hand track chiain beam.
The workpiece of dotted line is a right-hand track chiain beam 31 among Fig. 4, is fixed in the queen post crawler crane crawler belt beam assembling positioner.The right-hand track chiain beam is provided with one group of thrust wheel 32, and it is fixing that each thrust wheel all passes through a plurality of bolts (for example 4 bolts).The top is vertical multiple-shaft tightening machine (for example vertical four tightening machine 41), and tightening machine 41 is suspended on the cantilever 43 through suspension apparatus 42, and cable 44 links to each other system's switch board 45 with tightening machine 41.Tightening machine 41 is used to tighten the protrusion on the crawler belt beam 31, and said protrusion is thrust wheel 32, and these four rectangular array distribution of bolt, can disposablely be tightened simultaneously by four tightening machine.
The concrete operations flow process is:
The operation twin columns are laterally adjusted leading screw 8, 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 the crawler belt beam two twin columns hypotelorisms in every group of twin columns assembly with twin columns, operate twin columns tensioner screw mandrel 7 with the twin columns tensioner, fixedly the crawler belt beam.Operate vertical four tightening machine and tighten the bolt on the thrust wheel, fixing thrust wheel, tighten finish after; With 180 ° of positioner displacements (specifically refineing to the concrete parts of operation positioner), operate twin columns tensioner screw mandrel 7 again, twin columns are unclamped; Hang away the crawler belt beam, end of operation.
The positioner principle: this tipper mainly is to adopt the mechanical type transmission.
The crawler belt beam divides two kinds on left crawler belt beam and right-hand track chiain beam, and profile has than big-difference, so left and right sides crawler belt beam is also different with tipper closure; When left crawler belt beam is installed, two groups of twin columns of positioner are turn to diagram vertical view position, again with the crawler belt beam on two square holes be connected; Operation 7 (leading screws) reach the fixedly purpose of crawler belt beam with two groups of twin columns tensioners, operate positioner then and are rotated counterclockwise 180 °; Until running into lead limit switch, positioner stops the rotation.
The operation of right-hand track chiain beam and left crawler belt beam is opposite, at the crawler belt beam with before positioner is connected, need be with positioner Rotate 180 in the vertical view ° (being the position of positioner after the left crawler belt beam upset), all the other operate identical with above-mentioned left crawler belt beam.
In addition, as shown in Figure 7, said rotary system also can comprise hydraulic unit driver 74; Roller is arranged on the turning rolls 75, and said hydraulic unit driver 74 drives roller and rotates, and roller is transferred to upset gear ring 71 with power; Upset gear ring 71 internal fixation crawler belt beams 31, thus the crawler belt beam is rotated.
Said rotary system also can comprise reel and steel wire rope, is overturn by reel and steel wire rope combination pulling rollover stand.
Said rotary system also can comprise reductor, sprocket wheel 76 and chain 73, and reductor drives sprocket rotation, and the chain pulling rollover stand on the sprocket wheel overturns.
