Abstract
The utility model relates to an electromagnetism and permanent magnetism combined elevator which comprises a permanent magnet, a coil and an absorbing plate, wherein two ends of the permanent magnet respectively extend downwards to form a pin; the coil is wound on the permanent magnet; and the absorbing plate is fixedly held at the bottom of the pin and is arranged horizontally. As for the electromagnetism and permanent magnetism combined elevator, by arranging the coil on the permanent magnet, fast unloading can be realized only by changing the current direction of the coil; and simultaneously the elevator is provided with the absorbing plate, so that the absorbing area is enlarged, therefore, the elevator is applicable to hoisting heavy objects with a larger area.
Description
[technical field]
The utility model relates to a kind of weight-lifting equipment, is specially the weight-lifting equipment of a kind of electromagnetism, permanent magnetism combination, belongs to the elevator machinery technical field.
[background technology]
Lifting magnet equipment can be divided into two kinds of electromagnetism lifting and permanent magnet hoistings, and they respectively have merits and faults, but permanent magnet hoisting is more favored now, has a extensive future.The essential characteristic of permanent magnet hoisting device is: in the hoisting operation process, do not need galvanization, lean on the magnetic force of powerful permanent magnet that ferromagnetic workpiece liftings such as iron and steel are got up.Therefore, for traditional electromagnetic type lifting, the great advantage of permanent magnet hoisting is to save the energy.Because there is not the problem that has an accident because of power failure, so another advantage of permanent magnet hoisting device is safe and reliable.Owing to do not need to install the anti-power failure device, therefore help cost-cutting again.Generally speaking, the volume and weight of permanent magnet hoisting device, more small and light than the device of the electromagnetic type of peer.
But permanent magnet hoisting equipment also has some defectives, and such as how unloading fast heavily, this is a pendulum urgent problem in the field of business, though the method for some solutions has been arranged at present, it is slower that workpiece unloads heavy speed, and production efficiency is low.Simultaneously, the weight-lifting equipment adsorption area of prior art is little, is unfavorable for the lifting of plate objects such as similar steel plate, causes easily deforming in the lifting process.
Therefore, in order to solve the problems of the technologies described above, necessaryly provide a kind of weight-lifting equipment, to overcome described defective of the prior art with structure improved electromagnetism, permanent magnetism combination.
[utility model content]
For addressing the above problem, the purpose of this utility model be to provide a kind of unload fast heavy, and the big electromagnetism of adsorption area, the weight-lifting equipment of permanent magnetism combination.
For achieving the above object, the technical scheme that the utility model is taked is: the weight-lifting equipment of a kind of electromagnetism, permanent magnetism combination, and it comprises permanent magnet, coil and adsorption plate; Wherein, described permanent magnet two ends extend to form a leg respectively downwards; Described coil is set around on the permanent magnet; Described adsorption plate is immobilizated in the bottom of leg and is and is horizontally disposed with.
The weight-lifting equipment of electromagnetism of the present utility model, permanent magnetism combination further is set to: the polarity of described permanent magnet two legs is opposite.
Compared with prior art, the utlity model has following beneficial effect: the weight-lifting equipment of electromagnetism of the present utility model, permanent magnetism combination is by being provided with coil on permanent magnet, therefore, the direction of current that only needs to change coil can be realized unloading fast heavily; Simultaneously, this lifting setting is provided with an adsorption plate, thereby has enlarged adsorption area, and therefore, this lifting setting is applicable to the bigger weight of lifting area.
[description of drawings]
Fig. 1 is the schematic diagram of the weight-lifting equipment of electromagnetism of the present utility model, permanent magnetism combination.
[specific embodiment]
See also shown in the Figure of description 1, the utility model is the weight-lifting equipment of a kind of electromagnetism, permanent magnetism combination, and it is made up of several parts such as permanent magnet 1, coil 2 and adsorption plates 3.
Wherein, to extend to form the polarity of a leg 11, two legs 11 respectively downwards opposite at described permanent magnet 1 two ends.
Described coil 2 is set around on the permanent magnet 1.
Described adsorption plate 3 is immobilizated in the bottom of leg 11 and is and is horizontally disposed with.
The restitution that unloads of the weight-lifting equipment of electromagnetism of the present utility model, permanent magnetism combination is managed as follows: feed electric current in coil 2, the magnetic field of its generation and the magnetic field of permanent magnet 1 generation are just offset, can realize unloading fast heavily.
Simultaneously, the weight-lifting equipment of electromagnetism of the present utility model, permanent magnetism combination is by being provided with an adsorption plate 3, thereby enlarged adsorption area, and therefore, this lifting setting is applicable to the bigger weight of lifting area, makes weight not yielding.
The above specific embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within made any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
