Description
Technical field
The present invention relates to container wharf or the stockyard supporting power supply technique of rubbertyred container gantry crane, specifically be used for automatic electricity getting system and the automatic power taking method of tire type gantry crane.
Background technology
Along with the lifting of price of oil going up sky-high and environmental demands, the power of rubbertyred container gantry crane (RTG) changes electric power into by fuel oil has become a kind of trend.An important link is exactly how civil power to be got on the RTG that needs long distance moving in the driven by power RTG technology.
At present means commonly used are the power taking support to be set in that the runway of RTG is other, and the trolley with city's electric connection is installed on the power taking support, then also need to use a current-collecting cart that moves with RTG.Dolly is electrically connected with gauntry crane, and dolly is provided with current colector, and there is carbon brush the current colector end.During power taking current-collecting cart is installed on the power taking support, carbon brush is connected with trolley, thereby realizes the electricity on the trolley is got on the RTG.
A technical matters that in this process, needs to solve be how to be installed to dolly on the power taking support and realize dolly power taking and with being synchronized with the movement of RTG.
The most traditional mode is by the manual work mode: existing dolly is installed on the power taking support, then manually the plug of dolly is inserted in both are electrically connected, realized powering to RTG by artificial haulage cable dolly to the mode of trolley of plugging into again.This manual work mode wastes time and energy, inefficiency, and plug plug rainy day, and Danger Electric shock risk is arranged, safety is low.
Application number is the structure that 200910050482.0 Chinese patent application file discloses a kind of dolly of automatically plugging into, during power taking, the connecting device that is connected on the RTG is released the dolly level, dolly is pressed against on the guide plate of power taking support, the RTG drive dolly that advances, dolly relies on advance tractive force and guide plate bearing force to make a concerted effort to produce a component that makes progress under an effect that is located at the oblique guide plate on the power taking support, thereby be lifted to predetermined altitude, the realization dolly is entered the orbit, the current colector carbon brush imports in the trolley by a flaring guiding port again, realizes automatic power taking.
The electricity getting system of this structure relies on the pressure of connecting device, the ahead power of RTG and the cooperation realization dolly of oblique guide plate to enter the orbit, need be in oblique plate introduction segment is realized the above-below direction horizontal direction simultaneously to dolly accurate location, connecting device needs to provide enough large horizontal pressure (about 750KG) to dolly for this reason, the assurance dolly in whole importing process near guide plate.And the above-below direction dolly rises to predetermined altitude by slope guide plate, and hoisting force is oblique plate to the dolly lifting wheel perpendicular to the component vertically upward that the pressure of plate face produces, and produce enough hoisting forcees, and the enough large tractive force that advances just need to be provided.The concrete stressing conditions of dolly is accordingly: the dolly that weight moves forward with certain speed, when its lifting wheel touches oblique guide plate, oblique guide plate is produced impulsive force, this force reaction is in lifting wheel, the component that produces in the vertical direction is used for overcoming dolly gravity (about 150KG), dolly pressure causes the downward component of the downward component (greater than 50KG) of the friction force that produces between Wan Xiangqiu and the backup plate and lifting wheel and oblique interleaf friction power, therefore only vertically downward component just reaches more than the 200KG, oblique plate angle is 22 degree, therefore act on more than the Li Keda 220KG of lifting wheel, and the impulsive force of impact moment is more than 4～5 times of positive force of labor, therefore enter the orbit at every turn all can produce nearly 1 ton powerful impulsive force to lifting wheel and whole dolly framework, consequently how long this car uses not, just having occured repeatedly, the lifting wheel strut member deforms, what cause that dolly can not be raised should have height, and then causes road wheel, the accident that track adjusting wheel and track bump against.Although, afterwards the lifting wheel strut member was strengthened, this deformation is difficult for occuring, but this impulsive force can act on little frame, produce a clockwise tilt torque, be delivered on the plummer block housing bearing with spherical outside surface of the ball bushing that slides up and down and frame supported, and then damage these parts, therefore should impact influential greatly to machine life and reliability.In the whole process of entering the orbit, have a plurality of equilibrium of forces in addition, if a fluctuation, just may cause and enter the orbit unsuccessfully (as the air pressure of connecting device not, the rocking etc. of RTG), very high to the requirement of system.And the power that dolly is forced on the backup plate is pressurized air, provide in the compressed-air actuated pressure system, cylinder, change-over valve, Air compressor, limiting valve, tracheae, adaptor union, motor, belt, any one component working mal of sluicing valve all could cause air pressure not enough! The reliability of air compression system own is not high, and this servo-actuated property that is designed to telescopic boom when RTG walks must adopt the relatively little air compression system of resistance again.This just determine whole system the current-collecting cart most critical to import and export in the process reliability limited.In addition, also rely on connecting device to realize to the traction of dolly, in the whole walking process, connecting device is pressed over dolly on the power taking support all the time, and the little foundation settlement of power taking support load is little.And RTG when work load reaches 200 tons, at runway behind longer period of service, its Runway Beam basis is local can to produce larger sedimentation (even fracture), the Runway Beam basis can reach more than the 40cm with respect to the sedimentation difference of power taking bracket basis, and the dolly that said system provides is in the connecting device end, it fluctuates scope only about ± 10cm, therefore can't work at the serious place of sedimentation at all, and this dolly is subjected to the restriction of linear ball bearing slideway rigidity and current-collecting cart frame dimensional restriction, domain of walker has can not be done greatly, so just there is defective in design itself.
