Description
Technical field
The invention belongs to electric supply installation, specifically a kind of device that uses, gives tire type gantry crane supply network electricity in large cargo stockyard as port and pier.
Background technology
At present, the elevator machinery in the large cargo stockyard of each main harbour at home and abroad particularly is exclusively used in the gauntry crane of lifting container, and two kinds of types are arranged basically: a kind of is tire type gantry crane, and a kind of is the rail mounted gauntry crane.
The goods yard operation power of rail mounted gauntry crane on harbour is to use electrical network, the connection of its electric system, be that the current colector that is directly fixed on the crane body support contacts with trolley, be connected with trolley by cable drum by electrical network, current colector is connected with the electric system of hoisting crane.Because big electric current slide wire power supply mode requires than higher contacting between current colector and the trolley, current colector is when sliding, the fixed support of current colector and the distance of the side travel between the trolley can not surpass ± 15mm, and beating of vertical direction can not surpass ± 20mm; To be its rigid wheel walk on fixing track locomotive crane, is fixed on contacting between current colector and the trolley on the crane support, can reach above-mentioned requirements fully.Supply with gauntry crane with the electricity of electrical network and use, have that energy consumption is low, noise is little, Zero-discharge non-pollution, service expenditure and a lower advantage of operating cost.But because of complete machine is walked along trapped orbit, and be subjected to supply cable length and track restrictions, the operation of especially can not cutting to longitudinally.This power supply mode can only be applied on the automatic production lines and part rail mounted mechanical equipment that fixing orbit is arranged in the workshop at present.
The complete machine walking of tire type gantry crane, be to adopt 8 to turn to 90 air-inflation tyres of spending only, lateral deviation during walking can allow in the scope of ± 500mm, and therefore can cut to arrives arbitrary position operation of whole goods yard, and especially the handling to freight container is very flexible.But because the road wheel of tire type gantry crane is an air-inflation tyre, when large cargos such as loading and unloading container, complete machine is more serious beating of lateral oscillation and vertical direction, if contact power supply with trolley, can not guarantee good contact the between current colector and the trolley with the current colector that is fixed on the crane body support; Power by cable drum by electrical network simultaneously, need be very long because of cable, also can't reach the purpose of arbitrary position operation in the flexible stockyards such as whole freight container of cutting to.Keep its flexible operation of cutting to, can only use the diesel-electric set electric supply that carries at random.Use diesel-electric set electric supply, energy consumption height, noise are big, and discharge amount of exhaust gas is big, and service expenditure and operating cost are all very high.
How making gauntry crane can reach low cost, little noise, pollution-free operation, can realize the transition work of maneuverability ground again, is the problem that present large cargo stockyard mechanical work need solve.
Summary of the invention
Technical matters to be solved by this invention is, overcome existing rail mounted gauntry crane and be subjected to supply cable length and track restrictions, the operation of can not vertically cutting to, and tire type gantry crane provides a kind of electric supply installation of tire type gantry crane by diesel-electric set electric supply energy consumption height, noise is big, operating cost is high shortcoming.
In order to solve the problems referred to above that prior art exists, the present invention adopts following technical proposals to realize: on the fixed support of goods yard, set up and mains supply circuit bonded assembly wiping circuit, current colector with every trolley moving contact of wiping circuit, be fixedly mounted on the trolley trackside face that is positioned at, can parallel mobile dolly with trolley on, the pig-tail wire of current colector connects with the electric system of tire type gantry crane, and dolly and tire type gantry crane flexibly connect.
The present invention also has following technical characterictic:
Described parallel mobile dolly with trolley is the trolley both sides below fixed support, is fixed with the guide rail that wheel parallel with trolley, dolly rolls respectively in the above;
The guide rail of described trolley both sides is for striding trolley both sides and symmetrical horizontal distribution;
The guide rail of described trolley both sides, for striding trolley both sides and the horizontal guide rail that is symmetrically distributed and erectting guide rail, the wheel that is installed in the car frame is being erect on the guide rail with leaning against on the horizontal guide rail respectively;
The described wheel that is installed in the car frame is at horizontal guide rail with erect 8 to mounted in pairs of each 8 of being respectively the horizontal direction mounted in pairs on the guide rail and vertical cube;
On the head of the rear and front end of described car frame, be fixed with cushion rubber bumper;
Be positioned at the left and right sides on guide rail top in the described car frame, be fixed with its gib head anti-canting hook relative with orbital groove;
Described parallel mobile dolly with trolley is the centre of four trolleys below support, is fixed with the I-shape guide rail parallel with trolley, and the wheel on the dolly is respectively on " worker " word two sides of the I-shape guide rail of centre;
Described dolly and tire type gantry crane flexibly connect, an end that is the flexible drawing rope is connected on the vehicle frame of dolly, the other end is connected on the frame of tire type gantry crane, and described hauling rope is by forming with elastomeric traction belt and tightrope parallel with it and that be longer than traction belt;
Described hauling rope is connected with gauntry crane, for being connected the traction end, colluding the drag link end on hoisting crane, can pluck the hook that can hang.
Advantage of the present invention and good effect are, owing in freight container and other items stockyard, set up the slide wire power supply circuit of striding the operating area, when tire type gantry crane during in the operation of case district, required drive is supplied with trolley by custom-designed mechanical device with the electricity of electrical network, again by being installed in the current colector on the parallel travelling car with trolley, to the electric system power supply of hoisting crane.Can be in the storage yard operation district tire type gantry crane of shift position flexibly, drive dolly and on the guide rail parallel, move with trolley, can realize work covering to whole stockyard; When tire type gantry crane need be cut to another regional operation, to cut to after then cutting off being connected of power supply grid and tire type gantry crane electric system, its operation power line is connected with the slide wire power supply circuit of another operating area again.Like this, tire type gantry crane can keep maneuverability, the advantage of the operation of being convenient to cut to, and can realize low energy consumption, low cost, low noise and pollution-free power supply as the rail mounted gauntry crane again.
Through measuring and calculating, power to tire type gantry crane with diesel powerplant, its handling freight container use the diesel oil amount, average energy consumption is about 1.6 liters/case, by every liter of 4.7 yuan of calculating, single case energy consumption is about 7.52 yuan, annual maintenance cost is about 6.5 ten thousand yuan/platform; Single case energy consumption that the tire type gantry crane of employing mains supply hangs freight container is about the 2.5kWh/ case, calculates by every kWh0.91 is first, and single case energy consumption is about 2.27 yuan, and annual maintenance cost only is 0.3 ten thousand a yuan/platform.
By above-mentioned consumption calculations, use the operating cost of the tire type gantry crane of net electrical actuation power, be significantly less than operating cost with the tire type gantry crane of diesel-electric set electric supply.This shows that with the tire type gantry crane of net electrical actuation power compare with the tire type gantry crane with diesel-electric set electric supply, its economic benefit and social benefit are all very remarkable.
