Abstract
The utility model relates to a lifting jack driven by a cylinder and belongs to lifting apparatus used for lifting level sheet materials with various materials. The utility model is designed according to the 'Boyle-Mariotte's' law. A piston is driven to move up by a piston rod along a cylinder body. The inner cavity volume of the cylinder body of the lifting jack is enlarged. The gas pressure intensity of the inner cavity is reduced. The inner and the outer sides of the cylinder body of the jack forms pressure difference, so that the attracting force is generated to absorb the sheet materials to be lifted. The utility model has the advantages of simple structure, convenient operation, wide range of application, safety, wide usage for level sheet materials with any materials and no magnetization to the sheet materials. The jack unit can lift sheet materials with larger area.
Description
The utility model is the lifting appliance that belongs to the smooth sheet material of various materials.
At present, the hoisting method of various smooth sheet materials is to hang on the suspension hook after adopting cable wire to tie to lift by crane.Formality is cumbersome, and efficient is low.Also adopt magnetic chuck that sheet material is drawn the back lifting to ferrimagnetism sheet material.Magnetic chuck energy consumption height.Use dangerously, draw several sheet materials sometimes, and following sheet material is often inhaled insecurely, also might have a power failure or circuit et out of order and the sheet material that cuts off the power supply falls down.Magnetic chuck is only limited to the sheet material of lifting ferromagnetic material, for not allowing magnetized sheet material just can not use magnetic chuck.
It is a kind of simple in structure, easy to operate that the purpose of this utility model is to provide, and is suitable for the lifting appliance of the smooth sheet material of the various materials of lifting.
Main points of the present utility model are according to " Boyle---Ma Lvete " law design-calculated.Increase an airtight container inner volume.Gas pressure intensity reduces in it.This apparatus structure employing cylinder mode changes container volume and changes gas pressure intensity.In the working process, piston rod drives piston and moves up, thereby has increased hoisting device inner chamber of cylinder block volume, and the inner chamber gas pressure intensity is reduced, just form a pressure difference inside and outside the cylinder body, produce a size and equal the suction absorption sheet material that pressure difference multiply by the seal area of working seal circle.
The concrete structure of this device is that a piston that is moved up and down by the piston rod drive is set in cylinder body.The inferior part of the cylinder block outside face has reached hanging scaffold, the set collar inside face is sphere.Their threes link, and constitute a spherical pair.Rise on the hanging scaffold bi-bit bi-pass air valve is set, rise on the hanging scaffold lower surface working seal circle is housed.Upper cover of piston rod has one group of spring that plays buffer action.Fix a cylinder cap on the cylinder body, an orienting sleeve is set in the cylinder cap centre hole, cylinder cap also has an aperture, and the above space of piston is communicated with atmosphere.
The cylinder body of this device, a hanging scaffold, set collar also can be made integral structure without spherical pair connects.So just save this part sealing arrangement, improved sealing property.Make simply simultaneously, cost has also reduced.
Several hoisting devices that have spherical pair to connect are contained on the suspension bracket, form a hoisting device group.This hoisting device group can be lifted by crane larger area sheet material.During with hoisting device group lifting sheet material, require low to the sheet material planeness.When each part of sheet material not in one plane the time, be to connect owing to play a hanging scaffold with cylinder body, so the working seal circle on the hanging scaffold of each hoisting device of hoisting device group can be attached on the sheet material well with spherical pair.
The contrast accompanying drawing describes in detail this device below.
Accompanying drawing is the structural representation of air-cylinder type hoisting device.Wherein, 1-piston rod; The 2-cylinder cap; The 3-orienting sleeve; The 4-spring; The 5-cylinder body; The 6-piston; The 7-set collar; 8-plays hanging scaffold; 9-working seal circle; 10-bi-bit bi-pass air valve.
The air-cylinder type hoisting device that the utility model proposed, piston (6) are fixed on the piston rod (1), and piston and cylinder body adopt seal approach and cooperatively interact.Cylinder body (5) lower external face has reached hanging scaffold (8), set collar (7) inside face is sphere, and their threes link and constitute a spherical pair.Fix a T font cylinder cap (2) on the cylinder body, an orienting sleeve (3) is set in the cylinder cap centre hole.The orienting sleeve endoporus matches with piston rod, to strengthen the piston guide performance.Cylinder cap also has an aperture, and the above space of piston communicates with atmosphere, makes piston and cylinder body that relative motion can take place.Be with one group of spring (4) that plays buffer action on the piston rod (1), both ends of the spring is respectively on piston and cylinder cap.Rise on the hanging scaffold normally closed bi-bit bi-pass air valve (10) is set, rise a work close lasso (9) is housed on the hanging scaffold lower surface.
The utility model working process is as follows:
Open air valve, hoisting device is placed on the sheet material, makes piston move down into extreme lower position, and air valve is closed.Owing to rise under the hanging scaffold working seal circle is arranged, so at this moment inner chamber of cylinder block does not communicate with atmosphere.Piston rod is slowly mentioned.The drive piston moves up, and hoisting device inner chamber of cylinder block volume increases, and the inner chamber gas pressure intensity reduces, and cylinder body is inside and outside to form a pressure difference, draws sheet material thereby produce a suction.Piston constantly moves up, and suction constantly increases to when equaling panel weight, and sheet material is just sling.In the time that sheet material will be put down, open air valve.Inner chamber of cylinder block communicates with atmosphere.Pressure difference is zero, and suction disappears, sheet material by gravity and break away from hoisting device.
The utility model has the advantage of simple in structurely, easy to operate, safe and reliable, applied widely, can both use the smooth sheet material of any material, and sheet material is not magnetized that the hoisting device group can be lifted by crane larger area sheet material.
