Abstract
The utility model relates to a lifting device, particularly a permanent magnetic lifting crane automatically controlling material suction and discharge when lifting, which comprises a permanent magnet, a magnet box and a suction and a discharge controlling mechanisms. The utility model is characterized in that the magnet box capable of horizontally moving in a rectangular lifting rack, the permanent magnet and a magnetic conductor are arranged in the magnet box, the bottom of the rectangular lifting rack is provided with a sucking disc and the suction and the discharge controlling mechanisms are symmetrically arranged on both ends of the rectangular lifting rack. The utility model mainly utilizes the dead weight of a permanent magnetic crane to make a magnetic block do reciprocating movement in a machine body through a driving mechanism during working so as to realize the flow or cut-off of magnetism and achieve the goal of material suction or discharge. The utility model is a new technical product with high efficiency and energy saving without electricity and magnetizing, can be used for operational fields, such as metallurgy, machinery, shipbuilding, wharves, warehouses, underwater salvage, etc., and has unique superiority.
Description
Technical field
The utility model relates to weight-lifting equipment, and suction, blowing automatically controlled permanent magnet hoisting hang when referring in particular to lifting.
Background technology
The kind of lifting electromagnet, hoisting permanent magnet is a lot of at present, but all is that the dependence power supply carries out lifting or controls the logical magnetic of permanent magnet, disconnected magnetic with power supply.Not only cause range of use to be controlled, and charged complex structure, the guarantor's magnetic device that also need cut off the power supply, operation also makes troubles.The weight-lifting equipment more approaching with the utility model is " rotary type rare earth permanent magnet hoisting permanent magnet ", the magnetic group that makes a permanent magnet is rotated around anchor shaft and is caused the magnetic flux short circuit to lay down weight, the shortcoming of this permanent magnet weight-lifting equipment is: inhale (1), magnetic induction changes little when unloading weight, firmization of ferromagnetic object that influence is inhaled reduced permanent magnetism and inhaled Beijing South Maxpower Technology Co. Ltd's power; (2) owing to adopt the short circuit of rotary type mechanism controls magnetic group, the expense power consumption is big, and efficient is not high; (3) the permanent magnet protection is not good, easily oxidized, hydrogenation, and magnetic loss is serious, makes the magnetic hoisting hook life-span short.With the immediate weight-lifting equipment of the utility model is " parallel-moving type rare earth permanent magnet hoisting hook ", though it has adopted the mechanism of translation, but this translation is to utilize one group of rack-and-gear to pay, use motor-driven, with limit sensors control, not only increased cost, also with structure complicated.
Summary of the invention
The purpose of this utility model is improved at shortcoming that exists in the background technology and problem, provides that a kind of suction is strong, efficient is high, does not need power supply control can realize logical magnetic, disconnected magnetic, reaches the full automatic permanent hoisting hook of suction, blowing purpose.
The technical scheme that realizes the utility model purpose is: the utility model comprises permanent magnet, magnet case, inhales and put control mechanism, but its characteristics are to be provided with in the rectangle suspension bracket magnet case of parallel motion, permanent magnet and magnetizer are housed in the magnet case, rectangle suspension bracket bottom is provided with sucker, inhales and puts the two ends that control mechanism is symmetricly set on the rectangle suspension bracket.
The utility model mainly is the deadweight that utilizes permanent magnetism to hang, and in the course of the work, makes magnetic patch reciprocating in body by transmission device, thereby realizes logical magnetic, disconnected magnetic, reaches the purpose of inhaling blowing.The utility model need not electricity consumption, need not to magnetize, and is a kind of efficient, energy-conservation new science and technology product, has practicality widely, can be used for operation places such as metallurgy, machinery, shipbuilding, harbour, warehouse, underwater salvage, has unique advantages.

The specific embodiment
By Fig. 1,2 as can be known, the utility model comprises permanent magnet, magnet case, inhales and put control mechanism, its characteristics are rectangle suspension bracket (10) but the interior magnet case (7) that parallel motion is set, permanent magnet (9) and magnetizer (A3) are housed in the magnet case (7), rectangle suspension bracket (10) bottom is provided with sucker (8), inhales and puts the two ends that control mechanism is symmetricly set on rectangle suspension bracket (10).
Magnet case described in the utility model (7) is every magnet (AL) with the top all around to be formed, magnet case (7) both sides be provided with inhale put that control mechanism cooperates push away pin (6).Permanent magnet (9) and magnetizer (A3) in the described magnet case (7) rearrange uniformly at intervals.The described sucker (8) that is located at rectangle suspension bracket (10) bottom rearranges uniformly at intervals by magnetizer (A3) with every magnet (AL), and the both sides of rectangle suspension bracket (10) have the bevelled slotted eye, and the pin (6) that pushes away of magnet case (7) both sides is located in the slotted eye.Described suction is put control mechanism and is comprised reinforcement bar (1), elastic body (2), jointed shaft (3), push rod swivel pin (4), push rod (5), wherein jointed shaft (3) is located in the hanger at rectangle suspension bracket two ends, reinforcement bar (1) is located at the jointed shaft two ends, the galianconism end of reinforcement bar (1) connects push rod (5) by push rod hinge pin (4), the other end of push rod (5) touches and pushes away pin (6) on the magnet case (7), and elastic body (2) is located between reinforcement bar (1) and the push rod (5).
The utility model mainly is to put down by suspension rod mechanism---to mention the actuation cycle that---putting down---mentions again again, thereby the magnet case is moved on sucker, and it is open-minded to present magnetic circuit, and the two states of magnetic circuit short circuit makes Jack finish a suction---the process of blowing.At first suspension rod mechanism is put down, the boosting lever by gravity is set level, and the left side push rod pushes away from the magnet case and is close to it after pin slips over, and the right side push rod then pushes away the width of pin at a distance of a steel bar from the magnet case.Begin lifting, the left side push rod pushes away pin by the magnet case magnet case is pushed into the limit on the right-right-hand limit position, magnetic circuit is opened be in the suction state, and the right side push rod is pull-up already under the effect of spring force, just weight can be sling automatically.The utility model also unique design will push away pin translation short circuit magnetic circuit the time, make to push away pin an angle that makes progress is arranged, can make the magnet case on sucker, produce a gap like this, material thoroughly can be put clean.
