The specific embodiment
It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the present invention can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
Locomotive crane as shown in Figure 3, comprises cart walking mechanism, and the upper end of cart walking mechanism is provided with girder, and the lower end of cart walking mechanism is provided with a plurality of wheels, and wheel is provided with for driving the engine installation of rotation of wheel, and engine installation interval arranges; On locomotive crane, be also provided with controller, described controller can be controlled according to wind speed the quantity of in running order engine installation, the working quantity that is engine installation can change with the variation of locomotive crane work-yard wind speed, when wind-force is larger, the required power of drive track formula hoisting crane is larger, now, the quantity of in running order engine installation is more; When wind-force hour, the required power of drive track formula hoisting crane is relatively little, now, the negligible amounts of in running order engine installation.
In technique scheme, wheel is steel roller, is provided with saddle beam 5 between the supporting leg of support girder, on large saddle beam 5, is also provided with anchoring device.In one embodiment, engine installation is motor, motor is arranged between wheel top or two wheels, particularly, motor comprises the first motor 1, the second motor 2, the 3rd motor 3 and the 4th motor 4, wherein, the first motor 1 and the 3rd motor 3 are arranged at the left side of saddle beam 5, and the second motor 2 and the 4th motor 4 are arranged at the right side of saddle beam 5.In another kind of embodiment, engine installation is HM Hydraulic Motor and reductor, and HM Hydraulic Motor is arranged in reductor, and HM Hydraulic Motor is by Hydraulic Pump driven rotary, and HM Hydraulic Motor drives reductor rotation, and by reductor, wheel is driven.
On locomotive crane, be also provided with air monitoring equipment, controller is electrically connected to air monitoring equipment, and air monitoring equipment can be monitored the wind speed in rail mounted hoisting crane work place in real time, and in real time monitor value is transferred to controller.Air monitoring equipment is specifically as follows sensor, at this, does not do concrete restriction.In addition, controller is also electrically connected to engine installation, and the mode of operation of controlled braking force device.
In technique scheme, the power match value that wind speed and drive track formula hoisting crane are required,, according to wind speed configuration engine installation, can pre-enter to controller.During locomotive crane work, controller can calculate the needed power of drive track formula hoisting crane in real time according to air monitoring equipment, and according to power demand, selects the working quantity of required drive device, finally determines the mode of operation of engine installation.
Further, girder is horizontally placed on the cart walking mechanism upper end of locomotive crane, is also provided with maintenance crane on girder, is also provided with the dolly assembly for hoisting heavy between girder, it should be noted that, dolly assembly can move around on girder.Can also setting operation on girder other parts such as chamber, electrical house, specifically can be referring to prior art.
The locomotive crane of said structure, principle of work is as follows:
In locomotive crane working process, air monitoring equipment is passed to controller air speed value in real time, controller is calculated the required driving power of drive-type locomotive crane according to real-time anemograph, and the driving power that calculates is compared with pre-entering to the wind speed in controller and the matching value of power, determine to need how many engine installations to provide power for locomotive crane, and start and need in running order engine installation.
The locomotive crane of said structure, tool has the following advantages:
First, the inessential wearing and tearing of wheel have been solved.The locomotive crane of said structure, engine installation interval arranges, when the wind speed of locomotive crane working environment constantly changes, the working quantity of the engine installation of being controlled by controller is also in continuous variation, and when wind speed is larger, in running order engine installation is more, otherwise, less.Therefore, the normal walking of locomotive crane can be guaranteed, the wheel wearing and tearing that cause because power plant configurations is unreasonable can be reduced again.Meanwhile, also can avoid the low load factor of motor, in the low situation of power factor, move, reach energy-conserving action.
Secondly, intelligent degree is high, good economy performance.The locomotive crane of said structure, by air monitoring monitoring of equipment wind speed, and determines the engine installation quantity that needs work according to wind speed, and start the in running order engine installation of needs, therefore, degree of automation is higher, power configuration is more reasonable, and economy is better.
On the other hand, the present invention also proposes a kind of locomotive crane cart and drives control method, specifically comprises the steps:
Step S1: start locomotive crane;
Step S2: by air monitoring equipment, Real-Time Monitoring wind speed size, and real-time air speed value is passed to the controller of controlling to locomotive crane;
Step S3: controller, according to real-time wind speed, calculates the needed driving power of drive track formula crane;
Step S4: the driving power that controller is required according to locomotive crane cart, determine the quantity of required drive device, how many engine installations are in running order just can reach power demand;
Step S5: determine the mode of operation of engine installation, and start or close engine installation;
Step S6: drive track formula crane large vehicle walking.
Above-mentioned locomotive crane cart drives control method, can change the randomness of conventional arrangement driving wheel position, and orderly is configured engine installation.Meanwhile, according to the actual size of wind speed, select the configuration quantity of engine installation, select the number of driving wheel.So both guaranteed that equipment dynamic met the requirement of running power, meanwhile, again adhesion wheel had preferentially been configured in to the position of lateral pressure minimum, with this, reduced the heel and toe wear of wheel.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
