Description of drawings:
Fig. 1 is a scheme drawing of the present utility model
Fig. 2 is the scheme drawing that subtracts swing mechanism
The specific embodiment:
Below in conjunction with drawings and Examples the utility model is further described.
The utility model comprises door frame crossbeam 1, two door leg supports 2 and 3, the cart walking mechanism 4 of under door frame, walking, the dolly 5 that on door frame crossbeam 1, moves, with dolly 5 bonded assembly lifting mechanisms, it is characterized in that a support 2 is and crossbeam 1 rigidly connected rigid support that another support 3 is the flexible supports that flexibly connect with crossbeam 1 in these two door leg supports in two door leg supports.The section with crossbeam 1 rigidly connected rigid support 2 is trapezoidal among the embodiment, another support 3 flexibly connects to hinged with crossbeam 1, also be provided with in dolly 5 bottoms and subtract swing mechanism 7, this subtracts swing mechanism 7 and comprises drg 8, the brake wheel 9 that matches with drg 8, this brake wheel 9 is connected with a rotating shaft 10, in this rotating shaft, also be provided with first free-wheel clutch 11 and second free-wheel clutch 12, first reel 13 that has overlap in first free-wheel clutch 11 and the lifting mechanism is connected, second reel 14 that has underlap in second free-wheel clutch 12 and the lifting mechanism is connected, first reel 13 is connected with first torque motor 16 by first transmission device 15, and second reel 14 is connected with second torque motor 18 by second transmission device 17.Wherein first transmission device and second transmission device all are chain wheel pairs.In the left and right sides of dolly one cover is set respectively and subtracts swing mechanism, overlap universal coupling 19 of connection between two rotating shafts that subtract swing mechanism two.
According to embodiment of the present utility model, the gauge of this container gantry crane is that the distance between two door leg supports is 50m, and there is outreach at the crossbeam two ends, therefore adopt firm gentle two kinds of rack forms, rigid support and crossbeam adopt bolted connection, and flexible support adopts hinge to be connected with crossbeam.Because the pivotally attached flexible support can be swung around transverse horizontal axis, therefore can realize ideally that flexible support does not bear vertical equity load.And the section of rigid support 2 is trapezoidal, more helps a holding capacity.Can learn by calculating, in an embodiment of the present utility model, when cart moves, rigid support side cart wheel is 0.56 ton in the suffered side force of dolly direction, flexible support side cart wheel only is 0.054 ton in the suffered side force of dolly direction, less than the friction force between cart wheel and the track (about 1 ton),, thereby improved the serviceability of this container gantry crane so cart is difficult for gnawing rail in operational process.
In the loading and unloading container process, because rising of cart and dolly braked, make the acceleration and deceleration of suspender generation-individual hysteresis, and produce vertical and horizontal swing, had a strong impact on the accuracy of driver to freight container.In order to improve the traveling comfort of driver operation, reduce operation easier, on the dolly of this hoisting crane, be provided with the mechanical antirolling apparatus of two covers.
When reel was in the mode of operation of receiving rope, free-wheel clutch broke away from, and reel breaks away from rotating shaft and rotates voluntarily; When reel is in the mode of operation of putting rope, free-wheel clutch locking, reel and rotating shaft are rotated synchronously.Hoist when hoisting crane is in/during the decline operating mode, subtract and shake drg and open, make steel rope keep tensioning by torque motor, have only torque motor to play the slight effect of shaking that subtracts this moment; When hoisting crane is in the trolley travelling operating mode, subtract and shake arrester close, during the suspender swing, receipts rope side reel drags the disengaging rotating shaft by torque motor and rotates voluntarily, collects steel rope, for putting the rope side, suspender drags to subtract and shakes reel and rotating shaft and brake wheel and rotate together, thereby causes drg to produce a friction force on brake wheel, by this frictional heating, become the transformation of energy of suspender swing thermal energy consumption to fall, subtract the effect of shaking thereby reach.
When hanging eccentric freight container, when dolly quickened or runs slowly, the side rolling will take place in lift heavy.The most direct consequence that the side rolling causes has increased exactly to the case difficulty, has increased the case time, has reduced capacity rating.By machinery being subtracted the analysis of swing mechanism principle of work, with a length-adjustable universal coupling about two cover antirolling apparatuss be linked to be an integral body, just can improve machinery and subtract side rolling problem in shaking.
Subtract the principle of work of shaking according to machinery, have only reel to drive axle and rotate, make the brake wheel on the axle on drg, produce friction, make mechanical energy change into frictional heat energy, could realize subtracting shaking.When the side rolling takes place, with two cover drgs the big side of the amplitude of oscillation is subtracted earlier and shake, the little side of the amplitude of oscillation is not subtracted shake, when the both sides amplitude of oscillation equates, subtract simultaneously again and shake.Subtract swing mechanism and concentrate the full capacity on suppressing rapidly the big side rolling of harm earlier, suppressing influencing less yaw.So just shorten the time that the side rolling takes place greatly, improved the overall performance that subtracts swing mechanism.Be not difficult to find out that after handling like this, two cover drg sums shake subtracting of whole suspender and work, even the moment of two drgs has very big difference, do not subtract the effect of shaking as long as their lock torque with enough, just can not influence.Because the needs of dolly entire arrangement, about two cover antirolling apparatuss must guarantee bigger interval.Shake itself to concentricity and subtract the less demanding of the instantaneous difference in rotation of shaking on the reel and subtract, adopt universal coupling under the prerequisite of the work of assurance effect, greatly simplified mounting process.
