Detailed description of the invention
With detailed reference to accompanying drawing, embodiments of the invention are described now.Now with detailed reference to the preferred embodiments of the present invention, its example is shown in the drawings.In the case of any possible, in all of the figs the identical mark of use is represented same or analogous part.In addition, although the term used in the present invention selects from public term, but some terms mentioned in specification sheets of the present invention may be that applicant selects by his or her judgement, its detailed meanings illustrates in the relevant portion of description herein.In addition, require not only to pass through used actual terms, but the meaning that also will be contained by each term understands the present invention.
Fig. 1 schematically shows the added complete schematic of application eight ropes of the present invention.As shown in the figure, the added translation mechanism 100 of electric drive of the present invention mainly comprises: upper shelf structure 101, traversing carriage 102 and Vidacare corp 103.
One end of traversing carriage 102 is connected to Vidacare corp 103, and the other end of traversing carriage 102 is connected to dolly (not shown) via rope.Wherein, this dolly is placed on the added top of eight ropes.In horizontal direction, the added meeting of eight ropes follows dolly to move up in dolly side; On vertical direction, dolly drives cable drum to control added hoist action and down maneuver by motor.When added carry out the translation of cart direction time, then drive the translation mechanism of side, added extra large land, added relative trolley has the translation in horizontal cart direction; When adjusting added angle, then drive the translation mechanism of the added left and right sides, added relative trolley has the rotation of horizontal direction.Generally, eight rope side, added use extra large land translation mechanisms adjust added level attitude, use the translation framework of the left and right sides to adjust added angle.Preferably, this rope be steel rope or other possess the rope of enough tensile strengths.
Vidacare corp 103 is arranged on shelf structure 101 and also traversing carriage 102 can be driven to move, and to change the angle of above-mentioned rope, and then the angle of shelf structure 101 and position is finely tuned.
Forward now Fig. 2 A-2C to, wherein Fig. 2 A is the front view of traversing carriage of the present invention, and Fig. 2 B is the lateral plan of traversing carriage of the present invention, and Fig. 2 C is the cutaway view of the A-A line in Fig. 2 A.As shown in the figure, traversing carriage 102 may further include: connecting panel 201, roller 202, bearing 203, roller shaft 204 and connecting panel bearing pin 205.
Connecting panel 201 is fixed on Vidacare corp 103 by a plate bearing pin 205.Roller 202 is arranged on traversing carriage 102 by an axis of rolling 204, to make this traversing carriage 102 can at the screw mandrel case 306(of this Vidacare corp 103 as shown in Figure 3)) upper mobile, and traversing carriage sidesway can be prevented.
Forward Fig. 3 to now, Fig. 3 is the schematic diagram of Vidacare corp of the present invention.As described in Figure, Vidacare corp 103 of the present invention may further include: speed-reducing cycloidal motor 301, bearing seat 302, bearing 303, Connection Block 304, screw mandrel 305, screw mandrel case 306, nut 307, connecting panel 308, coder seat 309, coder cover 310 and coder 311.
Particularly, screw mandrel 305 is connected to speed-reducing cycloidal motor 301 via a bearing 303, and rotates under the drive of speed-reducing cycloidal motor 301.This bearing 303 is fixed by a bearing seat 302.As discussed above, traversing carriage 102 can move on screw mandrel case 306.
In addition, the rotation of screw mandrel 305 by drive nut 307 parallel motion, and drives above-mentioned traversing carriage 102 to do horizontal balance by a plate 308.Connection Block 304 connects with on upper shelf structure 101.
The coder 311 of Vidacare corp 103 can be used for detecting motor angle position and to the linear running distance of converting.The coder 311 of this Vidacare corp 103 can also calculate motor speed by the pulse count in the unit of account time, realizes accurately controlling.
In operational process, when needing after container hoisting to be placed on truck, often there is the deviation such as angle, distance, now needing to align the selvage of truck by adjusting the angle of freight container and position.Traversing carriage 102 one end of the present invention is connected with dolly (such as main carriage) by steel rope, and the other end connects with on Vidacare corp 103.Vidacare corp 103 is connected on shelf structure 101.When position and the angle of upper shelf structure 101 need be adjusted, Vidacare corp 103 drives traversing carriage 102 to move in main carriage direction, now the angle of steel rope can change, this change will make the angle and distance of upper shelf structure 101 finely tune, and freight container can be placed on truck trailer smoothly.
Those skilled in the art can be obvious, can carry out various modifications and variations and without departing from the spirit and scope of the present invention to above-mentioned exemplary embodiment of the present invention.Therefore, be intended to that the present invention is covered and drop within the scope of appended claims and equivalent arrangements thereof to amendment of the present invention and modification.
