Abstract
The utility model provides a novel crane and transport traction device, wherein a driving, a transmitting and a braking parts of the traction device on the same central line are all arranged in a drum, the driving part adopts a three-phase asynchronous motor with electromagnetic brake, and the transmitting part adopts a planetary gear system. Due to the integral design of driving, transmitting and braking is provided, the traction device has the advantages of a compact structure, small cubage, light weight, slow rotation speed, large output torque, reliable brake, and is applicable to the application of various situations.
Description
The utility model belongs to the weight-lifting equipment category, particularly a kind of novel lifting and draw gear.
At present, lack in lifting and freight department that a kind of volume is little, speed is slow, output torque is big, brake safe failure-free draw gear, for the slow traction object mainly replaces with winch.Yet, mostly the winch that uses mainly by electrical motor, reductor, drg, reel, and coupler forms, except that reel, other parts all are installed on the exterior split of reel and design, this just certainly will increase the installing space of winch.In addition, be subjected to the reel work speed of its reductor transferring power very fast.Limited at installing space, require the slower use occasion of work speed but to be subjected to certain restriction.The drg of its use is to adopt the electromagnet double block brake, and lever and hinge are many, and their distortion and wearing and tearing can cause the gap that is difficult to adjust, and causes the electromagnet motion to begin to have one section backlash, and has reduced the reliability of drg; The inertia of brake lever system is bigger, and combined floodgate and opening time are long; Waving of lever influences the stable of lock torque; If the braking component such as the surface of outer setting are stained with greasy dirt, can make the drg incapacitation.The safety and the reliability of winch braking are affected.
The purpose of this utility model provides a kind of driving, transmission and brake integration design-calculated novel traction device, its compact conformation, volume are little, in light weight, braking is reliable, speed is slow, output torque is big, and suit in various applications, to overcome existing slow traction object mainly with the alternative deficiency of winch.
The purpose of this utility model realizes with following technical scheme: a kind of novel traction device, it be is characterized in that by reel: the driving of draw gear, transmission and brake component all are arranged in the reel, and are arranged on the same line of centers.
Above-mentioned drive element adopts the three phase asynchronous motor of charged magnetic brake, and its magnet stopper places the motor reel rear portion, becomes one structure with motor drive mechanism.
Above-mentioned drive disk assembly adopts planetary train, the axle of electrical motor links to each other with the middle planetary wheel of first order planetary gear mechanism, the gear ring of final stage planetary gear mechanism is connected with reel, the kinetic moment that electrical motor is produced passes to reel by planetary train, realizes the deceleration transmission of power.
The progression of above-mentioned planetary train can be according to the speed setting of reel, and the rotating speed of its progression and reel is inversely proportional to.
Above-mentioned electrical motor is the electrical motor of province's decapsidate, with the stator of electrical motor and rotor direct mount in reel.
The utility model is compared the excellence that has with the alternative draw gear of existing winch and is: 1. volume is little, has made full use of the inner space of reel, has significantly reduced to take volume, has widened use occasion of the present utility model like this.2. compact conformation has saved between the electrical motor and drg of existing winch, and between drg and the reductor, the coupler between reductor and the reel has not only been simplified structure of the present utility model, and it is very convenient to make the utility model install.3. brake safe is reliable, drive and the three phase asynchronous motor of charged magnetic brake is adopted in braking, the axle of electrical motor directly and the first order be in transmission connection, make magnet stopper under the situation of electrical motor outage, braking immediately has the response time weak point, braking is rapid, safe and reliable characteristics.Overcome the drawback of existing winch braking.4. rotating speed is slow, and output torque is big, and drive disk assembly adopts planetary train, has compact conformation, and volume is little, and is in light weight, the characteristics that transmitting ratio is big.Therefore, guaranteed the output of low-rotate speed of the present utility model and high pulling torque.
Specify the utility model below in conjunction with drawings and Examples.
Accompanying drawing 1 structural representation of the present utility model.
Among the figure: 1 electrical motor, 2,3 first order planetary gear mechanisms, 4 middle planetary wheel, 5 second stage planetary gear mechanisms, 6 third stage planetary gear mechanisms, 7 reels, 8 magnet stoppers, 9 gear rings.
Embodiment: the driving of draw gear, transmission and brake component all are arranged in the reel 7 of same line of centers.Electrical motor 1 is the three phase asynchronous motor of the charged magnetic brake of province's decapsidate, and drive disk assembly adopts planetary train.The axle 2 of electrical motor links to each other with the middle planetary wheel 4 of first order planetary gear mechanism 3, through first order planetary gear mechanism 3, the transmission of second stage planetary gear mechanism 5 and third stage planetary gear mechanism 6, the gear ring 9 of last third stage planetary gear mechanism 6 is connected with reel 7.The kinetic moment that electrical motor 1 is produced passes to reel 7, has realized the deceleration transmission of power; The rotating speed of electrical motor 1 is reduced greatly, guaranteed slowly running of reel.Magnet stopper 8 places motor reel 2 rear portions, becomes one structure with motor drive mechanism.When electrical motor cut off the power supply, magnet stopper was braked immediately, made the electrical motor stall, thereby had guaranteed the safety and the reliability of braking.The progression of above-mentioned planetary train can be according to the speed setting of reel, and the progression of the low more planetary train of the rotating speed of its reel is high more.On the contrary, the progression of the high more planetary train of the rotating speed of its reel is low more.Make that use occasion of the present utility model is more extensive.
