The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is that the master of the utility model oleo gear looks cutaway view;
Fig. 2 is the enlarged drawing of end cap position among Fig. 1.
The specific embodiment
As shown in Figure 1, the utility model oleo gear comprises that base plate 1, pressure cylinder 2, plunger 11, adjust bar 22, orienting sleeve 7, end cap 14, upper spring seat 13, lower spring cup 3, spring 12, switch make bar 19 and switch 20.
In conjunction with shown in Figure 2, screw top at plunger connects end cap 14, deflation hole 32 is offered in the centre of end cap 14, be installed with sealing plug 16 at deflation hole, be provided with the first seal ring 17 between sealing plug 16 and the deflation hole 32, offer induction opening 1604 at sealing plug 16, induction opening 1604 is up big and down small stepped hole, air inlet valve 1602 is installed in induction opening 1604, air inlet valve 1602 comprises joint pin 161, termination 162 and baffle plate 163, termination 162 is fixedly connected on the upper end of joint pin 161, termination 162 is positioned at the macropore of induction opening 1604, the diameter of termination 162 is greater than the hole diameter of induction opening 1604, joint pin 161 passes the aperture of induction opening 1604, there is the gap between the hole wall of the aperture of the outer circumference surface of joint pin 161 and induction opening 1604, baffle plate 163 is fixedly connected on the lower end of joint pin 161, baffle plate 163 is positioned at induction opening 1604 belows, being provided with the second seal ring 1603, the second seal rings 1603 between the lower surface of baffle plate 163 and sealing plug 16 is sleeved on the joint pin 161.The first seal ring 17, the second seal ring 1603 all adopt the O RunddichtringO in the present embodiment.
At the fixing upper spring seat 13 of end cap 14, deflation hole is offered at upper spring seat 13 centers, upper spring seat 13 end faces are dash plate 15 fixedly, and deflation hole is offered at dash plate 15 centers, and the deflation hole 32 on the end cap 14, the deflation hole on the upper spring seat 13, the deflation hole on the dash plate 15 are interconnected.Fixing lower spring cup 3 on the lateral surface on pressure cylinder 2 tops, the upper and lower end of Compress Spring 12 is pressed in respectively between the upper and lower spring perch 13,3.Switch is beaten bar 19 upper ends and is captiveed joint with upper spring seat 13, pressure cylinder 2 lateral surfaces one side fixed installation switch bracket 18, switch 20 is contained on the switch bracket 18, and switch is beaten bar 19 lower ends and is positioned at locating of switch 20 contacts, beats when switch to contact with the contact of switch 20 when bar 19 descends.
Offer oil level porthole 33 on the pressure cylinder 2 upper end sidewalls, on the described oil level porthole 33 screw plug 6 is installed.Screw plug 6 is that metallic material or transparent material are made.The inner chamber of plunger 11 is communicated with by the cutoff port 41 on the flow bean choke 4 with the inner chamber of pressure cylinder 2.During oiling, back out sealing plug 16, refuel at deflation hole 32 places of end cap 14, fluid is in plunger 11 inner chamber feed pressure cylinders 2.Screw plug 6 can accurately and easily be observed oil level, prevents from having saved simultaneously oil-level measurement work owing to performance issue appears in the inaccurate energy disperser that causes of hydraulic oil injection rate, makes things convenient for the oil level inspection.When screw plug 6 is made for metallic material, during oiling, screw plug 6 is backed out, can confirm easily whether fluid is filled it up with.
When the dash plate 15 at lift car or counterweight cushion at collision top, plunger 11 moves downward, and the fluid in the pressure cylinder 2 overflows in the plunger 11 by the cutoff port 41 of the flow bean choke 4 of plunger 11 lower ends.When plunger 11 moved down, the end cap 14 that is fixed on plunger 11 upper ends drove upper spring seat 13 fixed thereon and moves down, thus the switch that is fixed on upper spring seat 13 1 sides make bar 19 and also move down, switch 20 is opened, make the towing machine outage.After lift car or counterweight left energy disperser, Compress Spring 12 resetted plunger 11 fully, and the contact of switch 20 automatically resets, and connected circuit, made it be in normal operating condition.When plunger 11 moves down, fluid overflows and is filled into plunger 11 inner chambers, the air that makes plunger 11 inside by high compression after, move up under the anticyclonic pressure of air inlet valve 1602 in plunger, by the second seal ring 1603, make the induction opening 1604 of sealing plug 16 be in closed state, fluid can not spray plunger by deflation hole, guarantee the leak tightness of energy disperser, can not cause the loss of fluid.In Compress Spring 12 reseting procedures, when the air inlet valve 1602 on the sealing plug 16 falls, owing to have the gap between the hole wall of the aperture of the outer circumference surface of joint pin 161 and induction opening 1604, fill into air by it, make plunger 11 internal pressure balances.In whole working process, there is not fluid to overflow outside the energy disperser, so do not need to safeguard and additional fluid.
When the command speed of elevator was 1 metre per second (m/s), the free height L of this energy disperser was the 210-230 millimeter, and when the command speed of elevator was 0.63 metre per second (m/s), the free height L of this energy disperser was the 160-180 millimeter..
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
