Abstract
The invention discloses a crane winch, which comprises a winding drum and a wall frame. The wall frame is provided with a motor and a speed reducer, the output end of the motor is connected with the speed reducer, the output shaft of the motor is connected with the rotating shaft of the winding drum, the rotating shaft of the winding drum is provided with a first gear, the wall frame is also provided with a shaft in a rotating manner, the shaft is fixedly connected with a second gear, the second gear is engaged with the first gear, the shaft is connected with an encoder, the encoder is electrically connected with a PLC (programmable logic controller), and the PLC is electrically connected with the motor. The number of turns of the winding drum is counted by the encoder. When the number of turns respectively reaches the set value of forward turns and the set value of reverse turns, a limiting signal is output by the PLC to control the motor to stop rotating, and a hook is stopped at the upper limit or the lower limit. The crane winch has the advantage that the structure is simple and can be realized easily.
Description
Technical field
The present invention relates to a kind of hoisting crane, relate in particular to a kind of winch of hoisting crane.
Background technology
Hoisting crane belongs to a kind of of elevator machinery, be a kind ofly circulate, the machinery of intermittent moment.Hoisting crane mainly comprises lifting mechanism, operating unit, luffing mechanism, swing type mechanism and metal construction etc.Lifting mechanism is the groundwork mechanism of hoisting crane, mostly is comprised of hangar system and winch.When working, walk about, and accept password, the indication of ground operating personal by the object that the steel rope that needs personnel constantly to pay close attention to winch is cared for winch for existing hoisting crane, cut off motor power with range estimation in good time, just in case make a fault, winch drum rotates transition, causes safety misadventure.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of winch of simple in structure, hoisting crane with limit function is provided.
The objective of the invention is to be achieved through the following technical solutions:
A kind of winch of hoisting crane, comprise reel and wall frame, on the described wall frame motor and speed reducer is installed, the mouth of described motor links to each other with reductor, the output shaft of described reductor links to each other with the rotating shaft of reel, the first gear is installed in the rotating shaft of described reel, the rotating axle that is provided with on the described wall frame, be fixedly connected with the second gear on the described axle, described the second gear and the engagement of the first gear, described axle links to each other with coder, and described coder is electrically connected with the PLC controller, and described PLC controller is electrically connected with motor.
Further, described the second gear is connected with axle key.
Further, described axle links to each other with coder by coupler.
Beneficial effect of the present invention is, the winch of described hoisting crane by coder to reel turning collar counting number, when the rotation number of turns reaches respectively forward setting value and counter-rotating setting value, limit signal of PLC controller output, thereby the control motor stops operating, so that suspension hook stops at the position of high-low limit, simple in structure, be easy to realize.
Description of drawings
Fig. 1 is the structural representation of the winch of a kind of hoisting crane of the present invention;
Fig. 2 is that the winch A of a kind of hoisting crane shown in Figure 1 is to view;
Fig. 3 is that Fig. 2 is in the cross-sectional schematic at B-B place.
Among the figure:
1, reel; 2, reductor; 3, the first gear; 4, motor; 5, wall frame; 6, the second gear; 7, coder cover; 8, coder; 9, cover plate; 10, coupler; 11, axle; 12, flat key.
The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment.
Please refer to Fig. 1 to shown in Figure 3, in present embodiment, a kind of winch of hoisting crane, comprise reel 1 and wall frame 5, motor 4 and reductor 2 are installed on the described wall frame 5, the mouth of described motor 4 links to each other with reductor 2, the output shaft of described reductor 2 links to each other with the rotating shaft of reel 1, the first gear 3 is installed in the rotating shaft of described reel 1, the 5 rotating axles 11 that are provided with on the described wall frame, be connected with the second gear 6 by flat key 12 on the described axle 11, described the second gear 6 is meshed with the first gear 3, and described axle 11 links to each other with coder 8 in being installed in coder cover 7 by coupler 10, and coder cover 7 rear ends are provided with cover plate 9, described coder 8 is electrically connected with the PLC controller, and described PLC controller is electrically connected with motor 4.
When the present invention works, by 8 pairs of reels of coder, 1 turning collar counting number, when the rotation number of turns reaches respectively forward setting value and counter-rotating setting value, limit signal of PLC controller output, thus control motor 4 stops operating, so that suspension hook stops at the position of high-low limit, simple in structure, be easy to realize, and easy to operate, effectively prevent the generation of safety misadventure.
Above embodiment has just set forth groundwork of the present invention and characteristic; the present invention is not limited by above-described embodiment; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
Claims (3)
