The specific embodiment
The present invention is intended to propose a kind of sling upper rack separation device, comprises the multiple-segment telescopic tube of socket successively, and the diameter of next joint telescopic pipe is less than a joint telescopic pipe and is enclosed within a joint telescopic pipe.Between two adjacent joint telescopic pipes, by plate chain, plate chain adapter plate, anodontia chain wheel assembly, be connected with plate chain tension means.The two joint telescopic pipes that separated hydraulic oil cylinder driving is adjacent stretch or shrink.
Between two adjacent joint telescopic pipes, anti-attrition piece is installed, telescopic pipe is led by anti-attrition piece when stretching or shrink.
In separated oil cylinder, comprise magnetic scale limiting device, magnetic scale limiting device is controlled the separating distance of separated oil cylinder.Because multiple-segment telescopic tube exists the effect of amplifying, the extension distance of telescopic pipe is greater than the separating distance of separated oil cylinder, and in one embodiment, the actual extension distance of telescopic pipe is three times of separated oil cylinder separating distance.
Plate chain tension means comprises plate chain regulating plate, adjusting screw(rod), jam nut, damping pad, hinge and bearing, by adjusting screw(rod), carrys out tensioning plate chain.
Anodontia chain wheel assembly comprises without toothed chain wheel bearing, without toothed chain wheel, bearing, jam nut, back-up ring, back-up ring, bearing pin and spacer ring for hole, describedly without toothed chain wheel bearing, is welded on telescopic pipe.
Fig. 1 and Fig. 2 have disclosed according to one embodiment of the invention sling upper rack separation device, and wherein Fig. 1 is front view, and Fig. 2 is birds-eye view.In the embodiment shown in Fig. 1 and Fig. 2, multiple-segment telescopic tube comprises first segment telescopic pipe 102, second section telescopic pipe 104, the 3rd joint telescopic pipe 107 and the 4th joint telescopic pipe 110 of socket successively.Separated oil cylinder 101 is fixed on first segment telescopic pipe 102 and second section telescopic pipe 104.
Between first segment telescopic pipe 102, second section telescopic pipe 104, the 3rd joint telescopic pipe 107 and the 4th joint telescopic pipe 110, by plate chain 105, plate chain adapter plate 106, anodontia chain wheel assembly 109 and plate chain tension means assembly 103, connect.
Fig. 3 is the enlarged drawing of A part in Fig. 1, has disclosed the structure of plate chain tension means assembly 103.As shown in Figure 3, link plate tensioning device assembly 103 comprises plate chain regulating plate 131, adjusting screw(rod) 132, jam nut 133, damping pad 134, hinge 135 and bearing 136.By adjusting screw(rod) 132, carry out tensioning plate chain 105.
Fig. 4 is the cross sectional view of B-B in Fig. 1, has disclosed the structure of anodontia chain wheel assembly 109.Anodontia chain wheel assembly 109 comprises without toothed chain wheel bearing, without toothed chain wheel 191, bearing 192, jam nut 193, back-up ring 194, back-up ring 195, bearing pin 196 and spacer ring 197 for hole.Without toothed chain wheel bearing, be welded on telescopic pipe.
The principle of work of the sling upper rack separation device of this embodiment is as follows: separated oil cylinder 101 stretches out and promotes first segment telescopic pipe 102 with 104 separation of second section telescopic pipe.Be fixed on anodontia chain wheel assembly 109 on second section telescopic pipe 104 and promote the 3rd joint telescopic pipes 107 and stretch out by being fixed on first segment telescopic pipe 102 and the 3rd joint telescopic pipe 107 upper plate chains 105, be fixed on equally anodontia chain wheel assembly 109 on the 3rd joint telescopic pipe 107 and promote the 4th joint telescopic pipes 110 and stretch out by being fixed on plate chain 105 on second section telescopic pipe 104 and the 4th joint telescopic pipe 110.During merging, by above-mentioned steps, oppositely realize equally, thereby realize sling upper rack separation and pooling function.The separating distance of sling upper rack is that the magnetic scale limiting device by being arranged in separated oil cylinder 101 is controlled.As described above, the actual separation of telescopic pipe distance equals the interior magnetic scale of separated oil cylinder 101 and detects three times of distance.
Sling upper rack separation device of the present invention is particularly useful for two 40 feet of suspenders.
Sling upper rack separation device of the present invention adopts telescopic pipe to replace scissors clamping-arm structure, solved the problem of the little and separated required thrust unreasonable distribution of stroke that scissors clamping-arm structure exists.
