Abstract
A separation mechanism for upper frame of lifting tool comprises multiple sections of telescopic tubes sequentially fitted over each other, wherein the next telescopic tube has a diameter smaller than that of the last telescopic tube and is fitted in the last telescopic tube; and two adjacent telescopic tubes are connected with each other through a plate link chain, a plate link chain fixing plate, a gear-free chain wheel assembly and a plate link chain tensioning device. A separating oil cylinder drives the two adjacent telescopic tubes to expand or shrink. By using telescopic tubes to replace the conventional scissor clamp-arm structure, the invention solves the problem of little stroke and improper pushing force allocation for separation.

The specific embodiment
The present invention is intended to propose a kind of sling upper rack separation device, comprises successively the multiple-segment telescopic tube of socket, and the diameter of next joint telescopic pipe is less than the upper class telescopic pipe and be enclosed within upper one and save in the telescopic pipe.Be connected with the plate chain tension means by plate chain, plate chain adapter plate, anodontia chain wheel assembly between the two adjacent joint telescopic pipes.Separating two adjacent joint telescopic pipes of hydraulic oil cylinder driving stretches or shrinks.
Between two adjacent joint telescopic pipes the anti-attrition piece is installed, telescopic pipe leads by subtracting module when stretching or shrink.
Separate in the oil cylinder and comprise the magnetic scale limiting device, the control of magnetic scale limiting device separates the separating distance of oil cylinder.Owing to there is the effect of amplifying in multiple-segment telescopic tube, the extension distance of telescopic pipe is greater than the separating distance that separates oil cylinder, and in one embodiment, the actual extension distance of telescopic pipe is three times of separation oil cylinder separating distance.
The plate chain tension means comprises plate chain regulating plate, adjusting screw(rod), jam nut, damping pad, hinge and bearing, comes the tensioning plate chain by adjusting screw(rod).
Anodontia chain wheel assembly comprise without the toothed chain wheel bearing, without toothed chain wheel, bearing, jam nut, hole with back-up ring, back-up ring, bearing pin and spacer ring, describedly be welded on the telescopic pipe without the toothed chain wheel bearing.
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 embodiment illustrated in figures 1 and 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 successively socket.Separating oil cylinder 101 is fixed on first segment telescopic pipe 102 and the second section telescopic pipe 104.
Connect by plate chain 105, plate chain adapter plate 106, anodontia chain wheel assembly 109 and plate chain tension means assembly 103 between first segment telescopic pipe 102, second section telescopic pipe 104, the 3rd joint telescopic pipe 107 and the 4th joint telescopic pipe 110.
Fig. 3 is the enlarged drawing of A part among 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.Come tensioning plate chain 105 by adjusting screw(rod) 132.
Fig. 4 is the cross sectional view of B-B among Fig. 1, has disclosed the structure of anodontia chain wheel assembly 109.Anodontia chain wheel assembly 109 comprises without the toothed chain wheel bearing, without toothed chain wheel 191, bearing 192, jam nut 193, hole back-up ring 194, back-up ring 195, bearing pin 196 and spacer ring 197.Be welded on the telescopic pipe without the toothed chain wheel bearing.
The principle of work of the sling upper rack separation device of this embodiment is as follows: separate oil cylinder 101 and stretch out promotion first segment telescopic pipe 102 with 104 separation of second section telescopic pipe.The anodontia chain wheel assembly 109 that is fixed on the second section telescopic pipe 104 promotes the 3rd joint telescopic pipe 107 and stretches out by being fixed on first segment telescopic pipe 102 and the 3rd joint telescopic pipe 107 upper plate chains 105, and the anodontia chain wheel assembly 109 that is fixed on equally on the 3rd joint telescopic pipe 107 promotes the 4th joint telescopic pipe 110 and stretches out by being fixed on plate chain 105 on second section telescopic pipe 104 and the 4th joint telescopic pipe 110.Oppositely realize by above-mentioned steps equally during merging, thereby realize that sling upper rack separates and pooling function.The separating distance of sling upper rack is to control by being installed in the magnetic scale limiting device that separates in the oil cylinder 101.As described above, the actual separation distance of telescopic pipe equals to separate oil cylinder 101 interior magnetic scales and detects three times of distances.
