Description
Technical Field
The utility model relates to a hydraulic tank, more specifically relates to a hydraulic tank breather valve mounting structure.
Background
A breather valve is required to be installed above the existing hydraulic oil tank to ensure that the inside of the oil tank is in a constant pressure state, so that a hydraulic system reaches the constant pressure state. The breather valve is usually fixedly mounted directly on top of the hydraulic tank. The operating mode of the decompression of the breather valve is that the dustproof cap fastened by threads is detached, the stud is pressed downwards by hand to carry out decompression, and the dustproof cap is screwed down after the decompression is finished.
The hydraulic tank is mounted on the machine, and a cover plate is usually laid on the top of the hydraulic tank to serve as a maintenance access or a standing platform. In order to facilitate the pressure relief operation of the breather valve, holes are usually formed in the cover plate, but according to the requirements of national standard GB/T17300-2017 'Earthwork mechanical channel device', spherical objects larger than or equal to 20mm are not allowed to pass through the holes on the surfaces of the walkways and the platforms above the areas where people usually walk, stand or operate. However, when the hole with the diameter of 20mm or smaller and other shapes is used for detaching the dust cap of the breather valve, the operation space is certainly insufficient, and the maximum size diameter of the dust cap is about 30mm, so that the pressure relief operation of the breather valve cannot be realized on the premise of the existing standard requirements. If the cover plate is not provided with a hole, the cover plate needs to be detached when the breather valve is decompressed. The cover plate is fixed at the top of the hydraulic oil tank by bolts, and the cover plate is detached to release pressure and then needs to be fixed again, so that inconvenience is brought to maintenance.
On some machines, a cover plate is not arranged above the hydraulic oil tank, and a top plate of the hydraulic oil tank is directly used as a maintenance channel or a standing platform. The breather valve is directly exposed outside at the moment. When standing on the platform or a maintenance worker passes through the maintenance channel, the raised breather valve can cause the maintenance worker to fall down when standing or walking, so that great potential safety hazards are caused.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is that the installation of current hydraulic tank breather valve causes the problem of potential safety hazard, and provides a hydraulic tank breather valve mounting structure, realizes making things convenient for the pressure release operation of breather valve, does not bring the potential safety hazard simultaneously, can be according to complete machine space nimble overall arrangement simultaneously.
The utility model discloses a realize that the technical scheme of its purpose is like: the utility model provides a structure hydraulic tank breather valve mounting structure, includes hydraulic tank, breather valve, its characterized in that still includes transition installation pipe, the first end of transition installation pipe is connected with hydraulic tank at hydraulic tank top and communicates with each other with hydraulic tank is inside, the breather valve is connected with the second end of transition installation pipe, the second end of transition installation pipe extends to hydraulic tank's side, for example near the oil tank easily carry out the pressure release operation and the convenient overall arrangement position of complete machine. The utility model discloses in, the breather valve is through the side that the transition installation pipe extends to hydraulic tank, and this is not only convenient to carry out the pressure release operation to the oil tank, also need not be for breather valve pressure release operation and trompil on the apron of hydraulic tank top simultaneously, has avoided the apron to go up the trompil and the potential safety hazard that arouses.
In the installation structure, the top of the hydraulic oil tank is provided with the air release joint, and the first end of the transition installation pipe is communicated with the interior of the hydraulic oil tank through the air release joint. Or a first breather valve mounting seat is installed at the top of the hydraulic oil tank, and the first end of the transition mounting pipe is communicated with the interior of the hydraulic oil tank through the first breather valve mounting seat. When the direct mount breather valve on current hydraulic tank, set up the mount pad of an installation breather valve (be first breather valve mount pad promptly) at the oil tank top, to realizing on this kind of hydraulic tank the technical scheme of the utility model, can be with transition installation pipe snap-on first breather valve mount pad, and need not change hydraulic tank's structure.
In the installation structure, the second end of the transition installation pipe is provided with a second breather valve installation seat, and the breather valve passes through the second breather valve installation seat and the transition installation pipe is connected. Further, the transition installation pipe is a flexible pipe. Or the transition installation pipe is a rigid hard pipe.
In the above mounting structure, the second end of the transition mounting pipe is fixed to the side surface of the hydraulic oil tank.
Compared with the prior art, the utility model discloses in, the breather valve is through the side that the transition installation pipe extends to hydraulic tank, and this not only conveniently carries out the pressure release operation to the oil tank, also need not be for breather valve pressure release operation and trompil on the apron of hydraulic tank top simultaneously, has avoided trompil on the apron and the potential safety hazard that arouses.
