Abstract

The utility model relates to an electric single-beam crane whose main beam adopts an H-shaped I beam or a box beam; the longitudinal running motor, the brake and the speed reducer of the running gear are combined into a whole; both the running motor and the lifting motor are in conical double-winding type; one side of the main beam is provided with two chutes; a power supply and a cable for manipulation can move in the chute; an electric hoist is arranged at one side of the main beam. Compared with the traditional crane, the utility model has the advantages simple structure, convenient operation and strong safety, can change the operating and the lifting speed according to the requirement, can increase the lifting height, and is suitable for being used for low-rise factory buildings.

Description

Electric signle-beam crane

The utility model relates to a kind of mono beam overhead crane.

Before the utility model was made, the main beam structure complex forms of conventional electric single-beam crane also adopted steel plate welding, manufacturing process complexity, cost also high, gig in-to-in electric block be contained in girder below, limited lifting altitude; Vertically service meter, drg and retarder are by the coupler bonded assembly in addition, and be loosely organized, and singly-bounds or the splines of adopting are connected more between wheel and the axletree, are not easy to dismounting.

The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of mono beam overhead crane is provided.

The purpose of this utility model is finished by following measure:

Girder of the present utility model is a H shape steel I-beam or the box steel beam that is welded into steel plate.

Vertical service meter in the operating unit, plane drg and retarder three are connected as a single entity.

Be being connected between the axletree that retarder stretches out and the wheel by tapering locking.

The electrical motor that hoists in the lift system, the horizontal service meter in the operating unit and vertical service meter are taper duplex winding electrical motor.

One side of girder is equipped with several shaped steel, two parallel slideways are housed on it, the hanger device that several are being connected two rollers and suspension bracket is housed on little axle by a little axle is housed in the slideway, flat cable passes and is suspended on each interior hanger device of slideway, a cable power supply cucurbit power supply is introduced usefulness, and another root cable is handled control for the torch door and used.

Electric block places a side of girder, and opposite side is equipped with a counterweight.

Description of drawings:

Fig. 1 is an overall assembling scheme drawing of the present utility model;

Fig. 2 is the birds-eye view of Fig. 1;

Fig. 3 is the box girder structure scheme drawing;

Fig. 4 is a H shape steel I-beam structural representation;

Fig. 5 is the assembling scheme drawing that vertically moves the electrical motor, plane drg and the retarder that use;

Fig. 6 is the assembling scheme drawing of slideway roller and flat cable.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

Girder of the present utility model can be the box steel beam 2 that a H shape steel I-beam 1 or four block plates are welded into.In operating unit, vertically actuating device is on the output shaft by vertical service meter 8 plane drg 9 to be housed, gear in the gear that is equipped with on the electrical motor and the retarder 10 is through being connected with the end tooth of axletree 13 by the end tooth colligator 12 on the output shaft 11 after three grades of decelerations, and axletree leans on tapering to lock with wheel 14.Horizontal service meter 15 and vertical service meter 8 are that the employed single-winding motor of known technology is incomparable in hoist electrical motor 3 and the operating unit that the utility model is selected for use in lift system, and this duplex winding electrical motor can provide two kinds vertically, laterally to move and hoisting speed.One face down bonding of girder has 6 channel-section steels 16, the other end of channel-section steel is welded with two parallel slideways 17, being equipped with 20 in the every slideway is being connected two rollers 19 and on little axle the hanger device that suspension bracket 20 is formed is being housed by a little axle 18, flat cable 21 passes and is suspended on each interior hanger device of slideway, wherein the moving cucurbit power supply of a cable power supply is introduced and is used, another root cable is handled control usefulness for torch door 4, and this kind device can make the operator not move with hanging to carry.Electric block 5 in the lift system can place a side of girder and move on girder by motor 15 and wheel 6, and the opposite side of girder is equipped with a counterweight 7.

The utility model compared with prior art has following advantage: because the H shape steel I-beam that girder adopts, designs simplification also can be selected standard steel section, does not need to process more, has simplified technology, has reduced cost; It is best to adopt box girder structure vertically to reach horizontal rigidity, is applicable to the crane of big elevating capacity and large span; Because electric block is biased in a side of girder, has increased hoisting depth, reduces building height, thereby reduced construction cost; Longitudinal electric machine, plane brake and the decelerator Trinity have been simplified travelling mechanism; Power supply and manipulation cable have adopted flat cable, and are loaded in the hanger device, thereby operating personnel needn't be moved around with hanging to carry, and have improved operator's security; Select the double winding motor, need fast-assembling, hurry up, during efficiency operation, but fast turn-around need to prevent from starting, when braking is impacted, then can adopt microrunning.

Claims

1, a kind of mono beam overhead crane, be grouped into by H shape steel I-beam or with girder, end carriage, operating unit, lift system and the electric control part of box steel beam, it is characterized in that vertical service meter, plane drg and the retarder three in the operating unit is connected as a single entity; Be being connected between the axletree that retarder stretches out and the wheel by tapering locking; The electrical motor that hoists in the lift system, the horizontal service meter in the operating unit and vertical service meter are taper duplex winding electrical motor; Side at girder is equipped with several shaped steel, two parallel slideways are housed on it, the hanger device that several are being connected two rollers and suspension bracket is housed on little axle by a little axle is housed in the slideway, flat cable passes and is suspended on each interior hanger device of slideway, a cable power supply cucurbit power supply is introduced usefulness, and another root cable is handled control for the torch door and used; Electric block places a side of girder, and opposite side is equipped with a counterweight.
