Abstract
The utility model relates to an electromagnetic brake structure suitable for a 1: 1 toothless traction machine, which is composed of an electromagnetic core, a suction disc, a declutch connecting rod, a declutch eccentric crank shaft, an electromagnetic support ring, a tension spring, a declutch hand lever, a brake base, etc. When the traction machine is normally operated, an electromagnetic coil in the electromagnetic core is electrified, the electromagnetic core is sucked together with the suction disc, a brake arm is pushed aside by a crown bar on the suction disc and a brake strip is separated from a brake drum. When the electromagnetic coil losses electricity, the brake strip is tightly pressed on the brake drum by the pressure of a spring so as to make the traction machine stop.
Description
The utility model relates to a kind of elevator annex, is a kind of magnet stopper structure that is applicable to 1: 1 anodontia towing machine drum brake.
For the tooth towing machine is arranged, the volume of magnet stopper is to the almost not influence of overall appearance of towing machine, along with the development of anodontia traction technology with popularize, the volume of anodontia towing machine is done littler and littler, the size of magnet stopper just directly has influence on the overall appearance of towing machine at this moment, that is to say that the volume of magnet stopper also should reduce thereupon.But, anodontia towing machine is not because of there being intermediate reduction gear mechanism, the demand of braking force has been far longer than the tooth towing machine again, for the towing machine of same tonnage, have tooth and anodontia towing machine braking force to differ 15～20 times approximately, this also is a big difficult point of towing machine exploitation in present 1: 1.At present common magnet stopper structure such as accompanying drawing 1, in this kind structure, magnetic loop is by electromagnet core 2, outer end cap 1, suction post 4 and working gas gap S
3Four parts are formed, because magnetic loop is longer, have caused expenditure of energy big, and it is many that electromagnet produces heat, and the electromagnet temperature rise influences the service life of magnet coil, thereby has influenced the service life of whole magnet stopper.In addition, from accompanying drawing 1, as can be seen, in the magnetic loop of this kind scheme, has only S
3Area be effective adhesive area, the adhesive area is less, the suction-combining force of corresponding generation is also less, therefore, if the magnet stopper of making by accompanying drawing 1 scheme if use on 1: 1 anodontia towing machine, its volume can be very huge.This scheme also has some other defectives: must adopt NULL as the assembly that manually declutches, magnet coil also has polar requirement, has increased cost of product so again.
The utility model is at above these shortcomings and limitation, and it is little to have proposed a kind of volume, and adhesive strength is big, and adhesive power is little, and temperature rise is low, the electromagnet drg scheme of long service life.Its special advantages can adapt to it and twines than being in 1: 1 the anodontia traction system, promotes the use of 1: 1 anodontia traction technology for elevator industry a kind of practicality, rational magnet stopper scheme are provided.Accompanying drawing 2 is principle assumption diagrams of the present utility model, and it is mainly by electromagnet core 1, suction disc 2, push rod 4 and working gas gap S
1, S
2Form with magnet coil 3.Be characterized in: by the double-acting air gap magnetic loop that electromagnet core and suction disc are formed, magnetic loop is lacked and to outer closure, has been reduced the energy consumption of product, and temperature rise is descended, and in the service life of having improved magnet coil, can obtain double electromagnetic attraction simultaneously.In the utility model, the adhesive area of electromagnet and suction disc is formed S by two parts
1And S
2, and S
1And S
2Area identical, comparing with accompanying drawing 1 so just makes the adhesive area increase 1 times, that is to say that the electromagnetism the suction-combining force of generation has increased 1 times, when system's normal operation, magnet coil energising, electromagnet core and suction disc adhesive, the push rod that is fixed together with suction disc ejects, and reaches the purpose that declutches.When the magnet coil dead electricity, the pressure of the pressured spring that contracts is pressed on friction lining on the brake wheel, reaches the purpose of braking.As everyone knows, the braking strength of anodontia towing machine is very big, the spring pressure that produces braking force can reach 600～1000Kg, adopt traditional skid plate structure by the very difficulty that declutches manually, for this reason, the utility model has designed the special brake-loosing mechanism manually of a cover, utilizes eccentric crankshaft to produce the spring pressure that huge propulsive effort overcomes 600～1000Kg, reach the purpose of easy manipulation, the artificial brake-loosing mechanism of eccentric crankshaft is another important feature of the present utility model.
Description of drawings
Accompanying drawing 1 magnet stopper magnetic loop scheme drawing at present commonly used.
Accompanying drawing 2 magnetic loop scheme drawings of the present utility model.
Accompanying drawing 3 structural representations of the present utility model.
Accompanying drawing 3 is examples of the present utility model.Below in conjunction with accompanying drawing 3, the utility model will be further described.
Depend on shown in Figure 3, the electromagnet core 3 that magnet coil 4 is equipped with in inside with and the suction disc 5 that has a push rod formed the closed magnetic path of double-acting air gap, connect to one with bolt by support ring 6 and drg seat 8.The eccentric crankshaft 10 that declutches is installed on drg seat 8, the eccentric crankshaft 10 that declutches has been formed the system that manually declutches with the connecting rod 7 that declutches, the two covers system that declutches forms an integral body by drg seat 8 and extension spring 9, with brake control lever assembly 2, compression spring 1 and spring pull bar 12, the arrester bracket 13 common magnet stopper assemblies of forming.Two axial planes of eccentric crankshaft of declutching contact with the concentric circle arc plane that connecting rod had that declutches, and as arm of force enlarger, overcome spring pressure with this, reach the purpose that effect is declutched by manpower.Under emergency work condition, the maintainer can be by pulling the handle 11 that declutches of the crankshaft end that declutches, turning crankshaft, withstand the connecting rod that declutches, the connecting rod end face that declutches compresses the end face of suction disc, the push rod that is fixed on the suction disc is ejected, thereby make the brake strip on the brake control lever assembly leave brake wheel, so just realized manually declutching.When the towing machine normal operation, magnet coil is charged, and to electromagnet core, the push rod on the suction disc ejects and makes brake strip leave brake wheel the generation electromagnetic force with the suction disc adhesive, and towing machine can move.When system's dead electricity, the pressure of stage clip makes brake strip compress brake wheel, towing machine stop or braking deceleration.
