Described attaching parts can comprise by bolted connection in the clamping plate at last band iron middle part, laterally connect cross-arm and the adjustable connecting screw rod and the protection connecting rod of three contact slide blocks, described adjustable connecting screw rod and protect the lower end of connecting rod to be connected with cross-arm, and the upper end is connected with suspension.
Described suspension can be frame shape, comprises three crossbeams and three longerons.
Principle of work of the present invention: cable is placed on the wiping roller central slot, and the wiping roller promotes certain height with cable, contacts to guarantee that cable and wiping roller are stable.Wiping roller material is a brass, has guaranteed good electrical conductivity, and outside glass fibre reinforced plastic insulating plate plays the protective effect to the wiping roller.The wiping roller contacts with cable, by lead electric current is reached gauntry crane, and gauntry crane obtains electric power and carries out work.Particularly carry out when mobile at gauntry crane, the wiping roller still can with the cable closed contact, guaranteed the continuity of power supply.
The present invention adopts trolley to move electric power system, mainly is made up of suspension, attaching parts, contact slide block three parts.Wherein the contact slide block is a main working parts, is made up of wiping roller, glass fibre reinforced plastic insulating plate.Attaching parts is made up of adjustable connecting screw rod, protection connecting rod.The trolley system is fixed by the angle steel suspension, is connected to gauntry crane, provides continuous power supply for it moves, and guarantees that gauntry crane normally moves.
Each moving contact unit is made up of two wiping rollers, and two blocks of glass fibre reinforced plastic insulating plates are installed in two wiping roller both sides, carry out captive joint with M12 copper wire bar, and a band iron (35 * 4) is installed between glass fibre reinforced plastic insulating plate and the outside bolt.The contact slide block is by ∠ 75
2* 6 angle steel and M16 copper wire screw rod are connected with suspension bracket, can adjustment.One cover wiping electric power system is made up of three contact slide blocks, and three contact slide blocks are transversely arranged, and concrete spacing can be regulated voluntarily according to beam field electric power system actual conditions.
The cost analysis result that following casehistory the present invention and traditional dragon gantry crane electric power system compare:
Traditional dragon gantry crane electric power system adopts the spool scheme, every gauntry crane configuration 350m cable (5 cores, 70mm
2), length overall L=350 * 4=1400m, cable material valency=1400m * 240 yuan/m=336000 unit.Every gauntry crane need be seen two of lineman people, 1200 yuan of everyone monthly salary, and annual 10 months construction times, to calculate by 2 year duration, labour cost=8 people * 1200 yuan * October * 2 year=192000 yuan more than amount to 52.8 ten thousand yuan.
Adopt soft trolley of the present invention to move the electric power system scheme: every gauntry crane needs the expense (containing processing and erection cost) of trolley assembly:
1), glass fibre reinforced plastic insulating plate: 1.7kg * 20 yuan/kg * 6 piece=204 yuan;
2), contact block copper pulley: 6 * 200 yuan /=1200 yuan;
3), (∠ 75 for head
2* 6 angle steel): 8m * 7kg/m * 9 yuan/kg=504 unit;
4), suspension: 100m * 7kg/m * 9 yuan/kg=6300 unit;
5), other materials takes: 1000 yuan;
Total expense: 9208 yuan;
Four total expensess: 4 * 9208 yuan=36832 yuan.
25 squares of copper conductor: 700m * 3 * 4 yuan/m=8400 unit;
Expenses such as cross-arm, a few type folder, porcelain vase and electric wire: 17 places * 200 yuan=3400 yuan;
The trolley expense amounts to: 4.9 ten thousand yuan of the ≈ of 36832+8400+3400=48632 unit;
Calculating can get the present invention and save 47.9 ten thousand yuan of costs than traditional dragon gantry crane electric power system.
Suspension is by ∠ 75
2* 6 jiaos just are welded, and have easy, the firm stable of processing, advantage such as with low cost.Its structure is simple relatively, mainly act as the fixed contact slide block, guarantees its normal operation.
Advantages such as the power demands when sliding contact line mobile power supply device of the present invention can satisfy the gauntry crane running has cost low, and fault rate is low, and installation and operation is easy can be used for beam field gauntry crane electric power system (the gauntry crane track is equipped with ground protection).
