Abstract
An electric hoist comprises an auxiliary frame. A rotary table is arranged on the auxiliary frame, and a main hoist, a radiator, a control cabin, and a suspension arm are arranged on the rotary table sequentially from the back to the front. A main hook and an auxiliary hook are arranged on the suspension arm, an engine is connected with an electric generator via a double-axle driver, the electric generator supplies power to the rotary table, the main hoist and a motor of a main oil pump and is connected with a change-over switch, and an external power device is arranged on the change-over switch. The electric hoist overcomes defects of existing electric hoists, can adapt to complicated construction sites, can be powered by external power supply directly, and can be also powered by motive power thereof.
Description
Technical field
The utility model relates to the lifting crane field, the electric hoist that particularly a kind of doube bridge drives.
Background technology
At present, in the middle of some complicated construction processes, because the workyard is complicated, changeable; Cause adopting the electric hoist of single bridge, driving not suit at such sitework, for example because the relation of landform, single bridge drive electric hoist can't arrive; And the within the reach electric hoist can't satisfy the requirement of site operation because self hoisting capacity is lower, and prior electric crane work inefficiency; Consumption of fuel is high; Thereby influence the progress of engineering,, cause unnecessary loss so that incur loss through delay the duration.
Summary of the invention
The utility model technical matters to be solved provides a kind of electric hoist, has overcome the defective of above-mentioned existing electric hoist, adapts to the complex engineering place, does out of tradely except the external power supply of direct use, also can use the power of self to carry out operation.A kind of electric hoist comprises subframe, and subframe is provided with turntable; By back to preceding master winch, radiator, control cabin and the arm of being equipped with successively, main suspension hook, secondary suspension hook are installed on the arm on the turntable, big arm oil cylinder is connected with arm through hinge with the feeler lever oil cylinder; Master winch below one side is equipped with main oil pump, and main oil pump is connected with the feeler lever oil cylinder with big arm oil cylinder, and subframe is provided with operator's compartment; The subframe below is equipped with driving engine; Be provided with switch box in the subframe side, driving engine drives through the doube bridge bridge and is connected with electrical generator, and electrical generator is that the motor of turntable, master winch and main oil pump provides electric power; Electrical generator is connected with change-over swith, and change-over swith is provided with external power supply device.
Be provided with fuel tank and gas tank in the described subframe crossbeam.
Described master winch below also is equipped with moving counterweight, and moving counterweight can freely stretch between 0～1.2m under hydraulic-driven.
Four jiaos of described subframes and centre are respectively equipped with 1 secondary supporting leg and 6 balance supporting legs, and main oil pump is connected with the driving oil cylinder of secondary supporting leg with the balance supporting leg.
The electric hoist that the utility model provides, beneficial effect is following:
1, the connection mode through adopting doube bridge to drive can adapt to more complex engineering place, has also improved load-carrying ability; Driving engine drives through doube bridge and is connected with electrical generator; Can drive doube bridge through turn of engine and drive rotation; Then drive generator for electricity generation; For the motor of turntable, master winch and main oil pump provides electric power, make the utility model under the situation of not using external power supply, to use the power of self to carry out operation.
2, fuel tank and gas tank are located in the frame beam, and conserve space prevents that fuel tank from damaging.
3, the change-over swith that is provided with makes in the utility model use of power supply and self power outside and changes, and can directly utilize external source to carry out work and without fuel oil, practices thrift and reduce user's use cost and expense, adapts to the needs of different occasions.
4, the utility model applied range is specially adapted to the construction and installation of circuits such as telecommunications, electric power, wire television, post and telecommunications.
