Abstract
The novel winding type dual-drum hoist comprises a motor controller, a motor, a coupling and a winding type dual-drum hoist main body. The motor output shaft is directly connected with the main shaft of winding drums by the coupling and the turn button of the motor controller is used to regulate the rotational speed of the motor to control the rotational speed of the main shafts of the winding drums and then to regulate the rotational speed of the winding drums to realize changing the speed and the carrying capacity of the winding type dual-drum hoist. The utility model has the advantages of simple device, high work efficiency, a few electric energy consumption and convenient maintenance.
Description
The utility model relates to the double-drum hoist in the digging field of transport machinery.
Present known double-drum hoist drives the reel rotation with common alternating current dynamo by retarder, brake equipment mostly, because speed is single, be difficult to satisfy the needs of different freight volumes, thereby Applicable scope is very narrow, and efficient is lower.For satisfying in the actual production variation requirement to friction speed and different freight volumes, conventional art is normally: (1) installs magnetic clutch additional between motor and reel, realize changing the purpose of drum speed, when freight volume reduces, when drum speed reduces, the motor output speed is constant, its horsepower output also remains unchanged, cause a large amount of electric energy to waste, and magnetic clutch only is applicable to the low pressure small-capacity motor, efficient reduces with the rotating speed downward modulation, although it is relatively simple for structure, but infinite speed variation is restricted consumes energy but use.(2) add between motor and reel and load onto hydraulic coupler, this installs except that applicable to the big or middle capacity electrical machinery of high-low pressure, has the defective of above-mentioned magnetic clutch equally.(3) drive reel with pole-changing motor by retarder and brake equipment, though it has advantage of simple structure, but can not infinite speed variation (generally having only two speed), can not busy shift, be difficult to satisfy reality produce in to the requirement of multiple friction speed and freight volume, thereby not very good.(4) drive reel with DC machine, it starts steadily, adjustable-speed, and freight volume is variable, yet DC machine needs huge rectification and potential device that alternating current is become direct current (DC), and structure is very complicated, and is difficult in maintenance, consumed power, efficient is lower, and it is with high costs, is difficult to widespread use.
The purpose of this utility model just provides a kind of novel wound form double-drum hoist, and it is simple in structure, adjustable-speed, and freight volume is variable, and the efficient height is saved electric energy.
The purpose of this utility model is achieved in that novel wound form double-drum hoist is made up of electric machine controller, motor, coupler and wound form double-drum hoist body, motor is fixed on the gig underframe, motor shaft directly connects with spool spindle with coupler, regulate rotating speed of motor by the electric machine controller knob, control the rotating speed of spool spindle, and then the rotative speed of adjusting reel, realize changing the speed of wound form double-drum hoist and the purpose of freight volume.
The drive motor of novel wound form double-drum hoist can be AC stepless (or level an is arranged) buncher, because the high performance that alternating stepless speed regulating machine has, utilize alternating stepless speed regulating machine to regulate continuously to rated speed of rotation from " 0 ", but and the invertibility of braking ability and hand of rotation, the motor of this device directly connects with spool spindle, can select different speed according to needs of production, with in satisfy producing to the requirement of friction speed and different freight volumes.When freight volume reduced, motor speed reduced, and horsepower output reduces, and consumption of current descends thereupon, and productive costs is also reduced.Novel wound form double-drum hoist is compared with double-drum hoist in the past, and structure is more simple, safeguard very convenient, high efficiency, applied widely, save electric energy, remarkable in economical benefits improves, and is particularly suitable for concentrating at a distance automatic guidance.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Accompanying drawing is the constructional drawing according to the novel wound form double-drum hoist that the utility model proposes.
Describe in detail according to concrete device and the working process that the utility model proposes below in conjunction with accompanying drawing.
Novel wound form double-drum hoist is by the alternating stepless speed regulating machine controller, alternating stepless speed regulating machine, coupler and wound form double-drum hoist body are formed, alternating stepless speed regulating machine (2) is fixed on the underframe (6) of gig (7), alternating stepless speed regulating machine controller (1) connects with lead with alternating stepless speed regulating machine, and alternating stepless speed regulating machine output shaft (3) directly connects with spool spindle (5) with coupler (4).
By the rotating speed of alternating stepless speed regulating machine controller knob adjusting alternating stepless speed regulating machine, control the rotating speed of spool spindle, and then regulate the rotative speed of reel, realize changing the speed of wound form double-drum hoist and the purpose of freight volume.
But the AC step buncher that the alternating stepless speed regulating machine in the utility model is regulated with continuously smooth between every grade substitutes, and can reach above effect equally.
Coupler in the said apparatus replaces with gear pair, though the connecting mode difference is also in full force and effect.
Claims (5)
