The specific embodiment
See also Fig. 2～Fig. 4.The utility model fixed type eight ropes are put on the shelf and are comprised get-on carriage mechanism 2, the mid point of side all around at get-on carriage mechanism is provided with four suspension centres 21,22,23,24, link to each other with eight steel rope A of hoisting crane, there are four weight sensors 211,221,231,241 to be located at respectively on these four suspension centres of get-on carriage mechanism suspension bracket (as shown in Figure 5, this Figure only shows the structure of the weight sensor setting of a suspension centre, the structure that the weight sensor of its excess-three suspension centre is provided with is identical therewith).Because two steel ropes of each suspension centre place bonded assembly are herringbone, make and put on the shelf and suspender has rocking-prevention function on both direction.Be fixed with cable storage frame 25 and electrical control cabinet 26 at the get-on carriage mechanism top, in electrical control cabinet 26, be provided with control circuit 3.Also comprise a pair of frame mechanism 4,5 down, this is separately positioned on the bottom at get-on carriage mechanism two ends by connecting rod 41 to following frame mechanism 4,5; The point of connection of connecting rod and last undercarriage is all settled oscillating bearing, so can allow undercarriage relative displacement within the specific limits.
For realizing displacement all around, also being provided with oil cylinder and linking to each other between last undercarriage, specifically is to have disposed a left and right sides translation oil cylinder 6 at the middle part of get-on carriage mechanism, one end of this left and right sides translation oil cylinder is fixed on the bottom of get-on carriage mechanism, and the other end is fixed under the side on the frame mechanism; Translation oil cylinder 7,8, one front and back translation oil cylinders 7 were located between a side of following frame mechanism 4 and get-on carriage mechanism 2 before and after both sides had respectively disposed one, and translation oil cylinder 8 is located at down between the opposite side of frame mechanism 5 and get-on carriage mechanism 2 before and after another.The hydraulic power station that the propulsion source of oil cylinder can be installed from putting on the shelf or be connected to hydraulic power station on the suspender by the fast hydraulic pressure joint.
Built-in linear displacement transducer 61 in left and right sides translation oil cylinder 6, also distinguish built-in linear displacement transducer 71,81 at two front and back translation oil cylinders 7,8, the mouth of each linear displacement transducer and each weight sensor all is connected with the input end of control circuit 3 in the electrical control cabinet, thus the two-direction moving amount of control suspender and the load of each point.
Left and right sides translation oil cylinder in the middle of driving can make down the relative get-on carriage mechanism of frame mechanism left and right sides translation (cart direction) ± 250mm; Drive the front and back translation oil cylinder of left and right sides, then can make down relative get-on carriage mechanism front and back translation ± 200mm of frame mechanism or revolution ± 5 °.Because linear displacement transducer all is equipped with in left and right sides translation oil cylinder and translation oil cylinder inside, front and back, be responsible for the miles of relative movement and the moving direction of control and differentiation piston rod, therefore the electric control circuit action of each oil cylinder of automatic synchronization in view of the above, the synchronism and the harmony of assurance cylinder action.
See also Fig. 7, this is the schematic diagram of control circuit 3 of the present utility model.Fig. 8 is a schematic diagram of movements of the present utility model.Control circuit 3 of the present utility model comprises: control three groups of electromagnetic valve Y1-Y6 of three cylinder actions, the power module 31 of putting on the shelf, the CPU32 that puts on the shelf, the analog module 33 of putting on the shelf, the two wire system of putting on the shelf module 34, the two wire system of putting on the shelf modular power source 35 respectively.Among three groups of electromagnetic valve Y1-Y6 of three cylinder actions of control, if wherein one group obtain actuating signal after, this oil cylinder begins action, in-oil cylinder linear displacement transducer 61,71,81 reaches CPU32 and two wire modules 34 on putting on the shelf with shift simulation amount signal, count revolving die module 201 with two lines that the communication modes of AS-I two lines is transferred on the trolley frame 200, reach the CPU301 of crane mainframe 300 again, this host CPU 301 determines the action of oil cylinder in view of the above, to guarantee the synchronism of each oil cylinder; Equally, weight sensor 211,221,231,241 reaches CPU and two wire modules on putting on the shelf with the analog signals that detects, count the revolving die module with two lines that the communication modes of AS-I two lines is transferred on the trolley frame, reach host CPU again, this CPU judges load condition in view of the above, put on the shelf 100 oil cylinder 6,7,8 actions of control fixed type eight rope; As overload, promptly the driver to driver's cab 400 emits alarm.
See also Fig. 9, among the figure: P is an oil inlet end, and T is an oil revolving end, connects the sling hydraulic pressure system; S1-S6 is respectively the electromagnetic valve of three oil cylinders of control; 5A, 5B, 5C are respectively three pressure valve on the oil cylinder loop; 6A, 6B, 6C are respectively governor valves on three oil cylinder loops; Hydraulic oil enters pressure valve 5A, 5B, 5C and governor valve 6A, 6B, 6C by electromagnetic valve S1-S6, enters oil cylinder left and right sides translation oil cylinder or front and back translation oil cylinder at last.Control the sense of motion of oil cylinder by the oil-feed loop of control electromagnetic valve S1-S6.
The utility model has well two-way anti-shaking in actual use, and the driver can send instruction (driving oil cylinder action) and adjust the position of suspender so that to case according to the actual position of freight container again.When two side cylinders are stretched together or contract together, and following frame mechanism (being fixed together with suspender) get-on carriage mechanism do front and back translation relatively (moving range ± 200mm); When work of two side cylinders stretches out action, when another made contractive action, the relative get-on carriage mechanism of following frame mechanism was made gyroscopic movement (revolution range ± 5 °); When middle oil cylinder is made expanding-contracting action, can make down the relative get-on carriage mechanism of frame mechanism make left and right sides translation (range of translation ± 250mm).Can under the situation of motionless large vehicle walking or running trolley, carry out suspender fine motion (be generally 0～± 250mm), realize docking of suspender and freight container easily.
