Abstract
The invention discloses a long-distance transmission hydraulic cylinder. The long-distance transmission hydraulic cylinder comprises a cylinder barrel, a cylinder head arranged at the two ends of the cylinder barrel, a piston rod arranged in the cylinder barrel and a piston, wherein sealing devices are arranged on the piston and the cylinder heads. The long-distance transmission hydraulic cylinder is characterized in that an exhaust hole communicated with the inside of the cylinder barrel is formed on the cylinder barrel, and a silencer is arranged on the exhaust hole. According to the long-distance transmission hydraulic cylinder, the noise produced by exhaust is eliminated by arranging the silencer in the position of the exhaust hole, thereby improving a production environment, simultaneously preventing dust or sundries from falling into the oil cylinder and ensuring the normal working of the oil cylinder.
Description
Technical field
The present invention relates to a kind of hydraulic jack, particularly a kind of long Distance Transmission hydraulic jack.
Background technique
Hydraulic jack with hydraulic pressure can change mechanical energy into, the do straight reciprocating motion hydraulic actuator of (or oscillating motion).Its simple in structure, reliable operation.When realizing to-and-fro motion with it, can remove speed reducer from, and not have drive gap, therefore motion steadily is widely used in the hydraulic system of various machineries.Hydraulic jack is divided into piston type, plunger type, swing type and telescopic by structure type, wherein uses at most with piston-type hydraulic cylinder.
Piston-type hydraulic cylinder is divided into single-acting piston type hydraulic jack and double-acting piston hydraulic jack by the mode of action.Hydraulic jack on the transmission equipment adopts long stroke, single piston-type hydro compressing cylinder usually, and general stroke reaches can think long stroke oil cylinder more than the 600mm.Its structure comprises cylinder barrel, is arranged at the cylinder cap at cylinder barrel two ends, is arranged at piston rod and piston in the cylinder barrel, and piston and cylinder cap are provided with seal arrangement.Hydraulic jack is in assembling process or park when reworking for a long time; Also or in the piston rod movement process, can infiltrate air in the cylinder barrel, along with piston rod movement speeds up; When piston rod form during at rodless cavity; Bring the moment high temperature and high pressure of effect for this part gas space, have the potential safety hazard of blast, therefore need to discharge the air in the cylinder.
The method that adopts at present is that the highest point at hydraulic jack is provided with the venting aperture gas is discharged.Yet because the aperture is less, gas can produce the noise of screaming in the process of quick drain; Operating environment to the staff impacts, and because the venting aperture is opened on the cylinder barrel, causes dust and little foreign material to enter into hydraulic jack through the venting aperture; Get off for a long time, make the direct and impurity hard grind of piston rod, cause piston rod to be pulled; Even the damage seal arrangement, cause serious consequences such as hydraulic jack cisco unity malfunction.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: a kind of long Distance Transmission hydraulic jack, and through architecture advances, avoid foreign material to fall in the cylinder barrel, increase the service life; Eliminate generating noise simultaneously, for the staff provides the good working environment.
Technical solution of the present invention is achieved in that a kind of long Distance Transmission hydraulic jack; Comprise cylinder barrel, be arranged at these cylinder barrel two ends cylinder cap, be arranged at piston rod and piston in the said cylinder barrel; Be respectively equipped with seal arrangement on said piston and the said cylinder cap; Said cylinder barrel is provided with the exhaust port that is communicated with inner cavity of cylinder, and this exhaust port is provided with a baffler.
In the technique scheme, said exhaust port is positioned at head side nearby, and said baffler is for being with airfiltering baffler.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
1, on the cylinder barrel of the present invention exhaust port is set, baffler is installed on the exhaust port, in exhaust, remove noise, keep the good working environment through baffler;
2, have air filtering function on the baffler, can prevent that dust and other impurities from falling in the cylinder barrel, guarantee the normal use of oil cylinder, increase the service life.
Description of drawings
Below in conjunction with accompanying drawing technological scheme of the present invention is described further:
Fig. 1 is the structural representation of the embodiment of the invention one.
Wherein: 1, cylinder barrel; 2, front end housing; 3, back cylinder cover; 4, piston rod; 5, piston; 6, baffler.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Be illustrated in figure 1 as a kind of long Distance Transmission hydraulic jack of the present invention; Comprise cylinder barrel 1, be arranged at the front end housing 2 and the back cylinder cover 3 at these cylinder barrel 1 two ends; Be arranged at piston rod 4 and piston 5 in the said cylinder barrel 1, be respectively equipped with seal arrangement on said piston 5 and the said cylinder cap.
In the present embodiment, hydraulic jack is used for transmission equipment, and stroke is 600 ㎜; Pressure 28Mpa, said cylinder barrel 1 are provided with the exhaust port that is communicated with cylinder barrel 1 inner chamber, and this exhaust port is positioned at cylinder cap 2 end places nearby; Said exhaust port is provided with one and is with airfiltering baffler 6, through being with airfiltering baffler 6, eliminates the noise in the exhaust process; Prevent that simultaneously dust in air or other foreign material from falling in the exhaust port, guarantees the proper functioning of oil cylinder.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (2)
1. one kind long Distance Transmission hydraulic jack; Comprise cylinder barrel, be arranged at these cylinder barrel two ends cylinder cap, be arranged at piston rod and piston in the said cylinder barrel; Said piston and said cylinder cap are provided with seal arrangement; It is characterized in that: said cylinder barrel be provided with one with cylinder barrel in the exhaust port that is communicated with, this exhaust port is provided with a baffler.
