Description

Energy-conservation ground jack

Technical field:

This utility model relates to energy-conservation ground jack, belongs to ground jack technical field.

Background technology:

In industries such as machining, Making mold, metallurgy, some heavy steel plates, there is required precision Or have lifting and the transhipment of iron and steel processed finished products or the semi-finished product etc. of surface roughness requirements, the biggest Many employing steel wire rope binding recurrence are hung, or use lifting electromagnet lifting.Steel wire rope binding lifting Owing to manually to bundle workpiece every time, and some workpiece the most do not bundle a little, therefore handling workpiece The most bothersome, efficiency is the lowest, and easily hinders surface.Lifting electromagnet lifting is due to lifting electromagnet originally Body volume is big, and electric control system is complicated, and cost is high, and fault is many, difficult in maintenance, and lifting electricity Magnet at work, will consuming substantial amounts of electric energy, power failure phenomenon once occurring, although having the sixth of the twelve Earthly Branches now Power failure magnet keeper, but owing to equipment is complicated, the most easily there is security incident.

Occur in that the most on the market permanent magnetic lifter to solve an above difficult problem, permanent magnetic lifter work former Reason is to be realized magnetic conduction material by the magnetic circuit relation of two pieces of magnets in handle control ground jack housing Journey is let slip in the suction of material, generally when two magnets be homopolarity arrange time two pieces of magnets magnetic fields directions identical, Magnetic field passes housing and constitutes loop and drawn weight, when two magnets be heteropole arrange time two pieces of magnets Only constitute magnetic loop in enclosure interior, thus loosen weight.Permanent magnetic lifter in lifting process Overall weight be often significantly smaller than by lifting objects, therefore it is required that permanent magnetic lifter housing has relatively High intensity.It is directly connected on housing due to suspension ring during the most actually used, because of This junction tends to cause deformation, affects the normal use of permanent magnetic lifter.And due to Magnet Suction very big, more difficulty pulled by permanent magnetism device handle, thus have impact on the smooth unloading of workpiece.And Existing permanent magnetism device does not insure stopping means, therefore poor safety performance.

Utility model content:

For the problems referred to above, the technical problems to be solved in the utility model is to provide energy-conservation ground jack.

The energy-conservation ground jack of this utility model, it comprise housing, fixed block, suspension ring, fixing magnetic piece, Through hole, mandrel, magnetic conductor, trip bolt, clutch shaft bearing, the second bearing, handle mount, Handle and limit button, the top of housing is fixedly installed fixed block, fixed block by trip bolt Being arranged above suspension ring, the middle part of housing is provided with through hole, is provided with mandrel in through hole, through hole Top is provided with fixing magnetic piece, and the outside of mandrel is welded with magnetic conductor, and the two ends of mandrel set respectively It is equipped with clutch shaft bearing and the second bearing, and handle is connected with mandrel by handle mount, through hole Two bottom sides is provided with limit button.

As preferably, the bottom of described housing is provided with V-shaped groove, and V-shaped groove is justified accordingly for sticking Used by cylindrical objects.

As preferably, described fixing magnetic piece has two pieces, and middle employing stainless steel material separates, and Corresponding magnetic conductor is also two pieces, centre also for separating design, so energy while enhancing magnetic field It is effectively prevented from the short circuit of magnetic force.

As preferably, described clutch shaft bearing, the second bearing are that stainless steel material is made, the first axle Hold and be easy to mandrel rotation with the second bearing, and also can be effectively prevented from the short circuit of magnetic force.

The beneficial effects of the utility model: it can overcome the drawback of prior art, structure adds up to rationally Novelty, uses double magnetic piece design, and magnetic property is strong, and therefore loading capacity is relatively big, and suspension ring are not direct It is connected with housing, housing will not be damaged, facilitate repair demolition, be provided with two bearings, solve Because suction is very big, pull the technological difficulties such as handle is highly difficult, it is achieved thereby that the smooth unloading of workpiece, And be additionally provided with limit button, spacing reliably, ensure its security performance.

Accompanying drawing illustrates:

For ease of explanation, this utility model is embodied as and accompanying drawing is described in detail by following.

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the plan structure schematic diagram of mandrel in this utility model.

Detailed description of the invention:

As shown in Figure 1-2, this detailed description of the invention is by the following technical solutions: it comprise housing 1, Fixed block 2, suspension ring 3, fixing magnetic piece 4, through hole 5, mandrel 6, magnetic conductor 7, trip bolt 8, Clutch shaft bearing the 9, second bearing 10, handle mount 11, handle 12 and limit button 13, shell The top of body 1 is fixedly installed fixed block 2 by trip bolt 8, and fixed block 2 is arranged above hanging Ring 3, the middle part of housing 1 is provided with through hole 5, is provided with mandrel 6 in through hole 5, through hole 5 upper Portion is provided with fixing magnetic piece 4, and the outside of mandrel 6 is welded with magnetic conductor 7, and the two ends of mandrel 6 are divided It is not provided with clutch shaft bearing 9 and the second bearing 10, and handle 12 is by handle mount 11 and core Axle 6 connects, and the two bottom sides of through hole 5 is provided with limit button 13.

As preferably, the bottom of described housing 1 is provided with V-shaped groove 1-1, V-shaped groove 1-1 for inhaling Hold used by corresponding cylindrical object.

As preferably, described fixing magnetic piece 4 has two pieces, and middle employing stainless steel material separates, And the magnetic conductor 7 of correspondence is also two pieces, centre, also for separating design, is so strengthening the same of magnetic field Time can be effectively prevented from the short circuit of magnetic force.

As preferably, described clutch shaft bearing the 9, second bearing 10 is made for stainless steel material, the One bearing 9 and the second bearing 10 are easy to mandrel 6 and are rotated, and also can be effectively prevented from the short circuit of magnetic force.

The operation principle of this detailed description of the invention is: when needs carrying workpiece, turning handle 12, Thus band moving mandrel 6 rotates, make fixing magnetic piece 4 and the N pole of magnetic conductor 7 and the most same phase time of S, Magnetic field intensity superposition, the magnetic line of force just can inhale workpiece the work at this ground jack firmly through workpiece On pole-face, turning handle 12, mandrel 6 drives magnetic conductor 7 to rotate, and makes fixing magnetic piece 4 and magnetic conduction When the N pole of body 7 and S pole out-phase, owing to the magnetic line of force has the characteristic of shortcut, so the magnetic line of force is not To the work pole-face of this ground jack, inside this ground jack, just form the closed-loop path of magnetic circuit, almost Do not have the magnetic line of force from the work pole-face of ground jack out, so workpiece will not be produced suction, just Unloading can be realized smoothly.

Of the present utility model ultimate principle and principal character and this utility model have more than been shown and described Advantage.Skilled person will appreciate that of the industry, this utility model is not limited by above-described embodiment System, simply illustrates principle of the present utility model described in above-described embodiment and description, is not taking off On the premise of this utility model spirit and scope, this utility model also has various changes and modifications, In the range of these changes and improvements both fall within claimed this utility model.This utility model requirement Protection domain is defined by appending claims and equivalent thereof.
