Description
Technical field
The utility model relates to a kind of hoisting crane, relates in particular to a kind of Novel electric block double girder crane.
Background technology
At present, in places such as machine manufacture, fitter's shop and warehouses, generally use electric hoist double-girder hoisting crane to carry out carrying and the handling of material.And existing electric hoist double-girder hoisting crane adopts traditional old-fashioned double girder bridge, old-fashioned electric block dolly mostly.Old-fashioned double girder bridge is made up of girder, operation LD transmission end carriage, old-fashioned electric block dolly by moving LD transmission, lifting mechanism is that CD (MD) type electric block forms, LD type transmission device, by meshed transmission gear, driving efficiency is low, and transmission noise is large.Meanwhile, existing electric hoist double-girder hoisting crane exist weld too much, complex structure, shortcoming that weight is large, and hoisting capacity is little, cannot meet client's user demand, has seriously had influence on the production efficiency of enterprise.
Utility model content
The purpose of this utility model is to provide a kind of Novel electric block double girder crane, can overcome the shortcoming of existing electric hoist double-girder hoisting crane, have advantages of simple in structure, weld nugget is few, from heavy and light, safe and reliable to operation.
The utility model adopts following technical proposals:
A kind of Novel electric block double girder crane, comprise and the crane span structure being horizontally installed on the large vehicle walking track of both sides, overhead, workshop, described crane span structure is made up of two girders that are bolted and two butt beams, every butt beam is provided with four large vehicle walking wheels, and large vehicle walking wheel is positioned at large vehicle walking track; The rear and front end of two butt beam opposite sides is provided with cart walking mechanism, and crane carriage walking track is all set on two girders, and the crane carriage running wheel of crane carriage both sides lays respectively in two crane carriage walking tracks on girder; Crane carriage is made up of lifting mechanism, crane carriage operating unit and crane carriage vehicle frame, lifting mechanism adopts electric block, reductor in electric block adopts planetary speed reducer, crane carriage operating unit adopts three-in-one Reducer, and crane carriage running wheel is arranged on crane carriage vehicle frame below; Crane carriage vehicle frame below is also hung with suspension hook by steel rope and assembly pulley.
Described crane span structure adopts local bias-rail box girder.
The described crane carriage running wheel side of employing bearing chamber structure, fixes by screw rod for four jiaos of square shaft bearing, and the spindle nose of crane carriage running wheel adopts rectangular spline structure, with the hollow spline connection for transmission of reductor.
Vertical distance between large vehicle walking track and crane carriage walking track is more than or equal to 115cm.
The utility model is by arranging the fixing girder of bolt and two butt beams, can either ensure reliability and commonality that girder is connected with end carriage, can also effectively reduce weld simultaneously, improved that the girder side sway causing due to welding deformation is excessive, cart end carriage distorts, and causes the phenomenons such as cart vehicle wheel line error is excessive; The utility model adopts eight wheeled cart operation scheme, can effectively reduce the wheel load of cart driving vehicle, planetary speed reducer in crane carriage lifting mechanism can reduce the space hold of crane carriage, can also alleviate the weight of crane carriage weight and whole girder, ensure the safe and reliable work of the utility model simultaneously; In the utility model, the spindle nose of crane carriage running wheel adopts rectangular spline structure, and with the hollow spline connection for transmission of reductor, stable drive, safety, transmitting torque is large, also has little, the lightweight advantage in wheel footpath, has good bearing capacity.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of crane carriage running wheel in the utility model;
Fig. 3 is the position view of large vehicle walking track and crane carriage walking track in the utility model.
Detailed description of the invention
As shown in Figure 1 to Figure 3, Novel electric block double girder crane described in the utility model, comprises crane span structure, traveling mechanism of the larger traveller 4 and crane carriage 1.Crane span structure is horizontally installed on the large vehicle walking track of both sides, overhead, workshop, described crane span structure is made up of two girders 2 that are bolted and two butt beams 3, girder 2 and end carriage 3 are bolted, can either ensure reliability and commonality that girder 2 is connected with end carriage 3, can also effectively reduce weld simultaneously, improve that girder 2 side sways that cause due to welding deformation are excessive, cart end carriage 3 is distorted, caused the phenomenons such as cart vehicle wheel line error is excessive.Every butt beam 3 is provided with four large vehicle walking wheels, and large vehicle walking wheel is positioned at large vehicle walking track.Owing to adopting eight wheeled cart operation scheme, can effectively reduce the wheel load of cart driving vehicle.The rear and front end of two butt beam 3 opposite sides is provided with traveling mechanism of the larger traveller 4, and traveling mechanism of the larger traveller 4 is driven by motor.Crane carriage walking track is all set on two girders 2, and the crane carriage running wheel 5 of crane carriage 1 both sides lays respectively in two crane carriage walking tracks on girder 2; Crane carriage 1 is made up of lifting mechanism, crane carriage operating unit and crane carriage vehicle frame, lifting mechanism adopts electric block, reductor in electric block adopts planetary speed reducer, the setting of planetary speed reducer can reduce the space hold of crane carriage 1, can also alleviate the weight of crane carriage 1 weight and whole girder 2, ensure the safe and reliable work of the utility model simultaneously.Crane carriage operating unit adopts three-in-one Reducer, and retarder, electrical motor and drg are integrated in one, and has the features such as output parallel with motor shaft, compact conformation, transmitting torque are large, stable working, noise is low, the life-span is long.Crane carriage running wheel 5 is arranged on crane carriage vehicle frame below; Crane carriage vehicle frame below is also hung with suspension hook 6 by steel rope and assembly pulley.Crane carriage running wheel 5 side's of employing bearing chamber structures, four jiaos of square shaft bearing 7 are fixing, easy for installation by screw rod 8.The spindle nose of crane carriage running wheel 5 adopts rectangular spline structure, and with the hollow spline connection for transmission of reductor, stable drive, safety, transmitting torque is large, also has little, the lightweight advantage in wheel footpath, also has good bearing capacity simultaneously.
In the utility model, crane span structure can adopt local bias-rail box girder, vertical distance H between large vehicle walking track A and crane carriage walking track B is more than or equal to 115cm, the utility model is by strengthening the vertical distance between large vehicle walking track and crane carriage walking track, the bracket height that can reduce large vehicle walking track bearing beam, has good social benefit.
