Description
Technical field
The present invention relates to a kind of hydraulic means, and in particular to the jacking apparatus of power is pushed up in raising.
Background technology
Jack is a kind of lifting highly small simplest crane gear, with rigidity top lift part as equipment, is led to
Cross the light small crane gear of top bracket or bottom claw the jacking weight in stroke.Jack is divided into mechanic jacks and hydraulic pressure
Two kinds of jack, principle is had nothing in common with each other.For from principle, hydraulic jack the principle on which is pascal's principle, i.e.,：Liquid
The pressure of body everywhere is consistent, and so, in the system of balance, the pressure that smaller piston upper applies is smaller, and
The pressure applied on big piston also than larger, can so keep the static of liquid.So by the transmission of liquid, can obtain
Different pressure on to different ends, can thus reach the purpose of a conversion.Mechanic jacks use theory of mechanics, with
Reciprocal to pull handle, pusher dog is to promote the revolution of ratchet gap, and cone pinion drives large bevel gear, rotates weight lifting screw rod, so that
Jacking sleeve is obtained raising or decline, and reach the function of lifting pulling force.But mechanic jacks are simple not as hydraulic jack.
Wherein, hydraulic jack is also known as hydraulic jack, is a kind of use plunger or hydraulic cylinder as rigid top lift part
Jack.Hydraulic jack compact conformation, stable working, there is a self-locking action, therefore use extensive.It has the disadvantage that lifting highly has
Limit.When using hydraulic jack jack-up weight to certain altitude, it is difficult to depress lever handle, user is caused to enter one
Step increases the lifting force of jack, so as to can not increase the jack-up height of weight.
The content of the invention
The technical problems to be solved by the invention are when using hydraulic jack jack-up weight to certain altitude, it is difficult to press
Lower lever handle, causes further increase the lifting force of jack.Therefore it is an object of the invention to provide in raising
The jacking apparatus of power is pushed up, solves when using hydraulic jack jack-up weight to certain altitude, it is difficult to depress lever handle, to cause
The problem of lifting force of jack can not further be increased.The present invention is the invention wound made on the basis of Pascal's law
Make.Pascal's law is a fluidstatic law, and Pascal's size is unchangeably transmitted from liquid to all directions.Pressure
Size according to static pressure fundamental equation：P=p0+ ρ gh draw, p0For additional pressure, ρ gh are original pressure, and p is change
Total pressure afterwards.Such as, the liquid in closed container is contained in, the pressure of itself is ρ gh, its additional pressure p0Change
When, as long as liquid still keeps the inactive state of its original constant, an equal amount of become will occur for the pressure of any point in liquid
Change.In other words, in closed container, the pressure put on inactive liquid will be with equivalent while pass to each point, i.e. p=p0+ρ
gh.Here it is pascal's principle, or Hydrostatic Transfer Device principle.
The present invention is achieved through the following technical solutions：
