Description

Bidirectional oil discharge pipe for hydraulic coupler

Technical Field

The utility model relates to a hydraulic coupling field, especially a two-way oil extraction pipe is used to hydraulic coupling.

Background

The speed-regulating hydraulic coupler is a transmission device which takes liquid as a power transmission medium and can meet the requirements of different working machines under different working conditions by regulating the rotating speed of an output end. The coupler discharges the working oil from the working cavity under the action of centrifugal force, so that the oil storage amount in the cavity is controlled to further play a role in regulating the rotating speed, and the speed regulating system of the coupler is realized. In the speed regulating system, the only device for discharging the working oil from the cavity is an oil discharge pipe (namely a scoop pipe), a special pipe orifice (namely a scoop head) is designed on the oil discharge pipe, the special pipe orifice must be correctly matched with the rotating direction of a working wheel of the coupler to be installed so as to discharge the oil out of the working cavity, and if the rotating direction is not consistent with the installing direction, the phenomena that the speed of the coupler cannot be regulated, the machine body vibrates and the like can be caused.

Under the current technical conditions, each coupler can only select an oil discharge pipe which is suitable for one rotation direction to be matched, so that the coupler can only fix one rotation direction, if the rotation direction of the coupler needs to be changed and oil discharge is smooth, the coupler can only be stopped and a connecting mechanism is disassembled to replace the oil discharge pipe in the other rotation direction again, even if the smoothness of the oil discharge is not considered, the coupler also needs to be stopped and disassembled to manually rotate the original oil discharge pipe by 180 degrees, and relatively more labor and time are spent. The method is used for project units which need frequent turning direction conversion or special working conditions which need temporary turning direction conversion but do not need field personnel to maintain; it is quite inconvenient in the field that there are no spare parts.

There is therefore a need for a method or apparatus that addresses the above-mentioned problems.

SUMMERY OF THE UTILITY MODEL

The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, rationally distributed can effectively prevent to reveal and not receive the hydraulic coupling of turning round to the restriction with getting rid of oil ring formula sealing mechanism.

The technical solution of the utility model is that: the utility model provides a two-way oil extraction pipe is used to fluid coupling which characterized in that: the oil drain pipe comprises a pipe body 1, wherein one end of the pipe body 1 is connected with a pipe orifice 2, the middle part of the pipe orifice 2 is provided with a partition plate 3, the partition plate 3 divides the inside of the pipe orifice 2 into two mutually isolated parts, the pipe orifice 2 is also symmetrically provided with two liquid inlets 8, the two liquid inlets 8 are respectively communicated with two cavities of the inside of the pipe orifice 2, the length of the partition plate is L1, the length of the pipe orifice 2 is L2, and L1 is more than L2, the tail end of the partition plate 3 is hinged with a semicircular turning plate 4, the inner wall of the pipe body 1 is provided with two limiting blocks which are symmetrically distributed and matched with the turning plate 4, the pipe body 1 is also provided with two symmetrically distributed liquid discharge ports 5, the liquid discharge ports 5 are positioned at the tail end of the partition plate 3, a protrusion 6 is also arranged in the pipe body 1, the protrusion 6 is wholly conical, and the protrusion 6 is positioned at the liquid discharge port 5, the tail end of the pipe body 1 is provided with a connecting base 7.

Compared with the prior art, the utility model, have following advantage:

the bidirectional oil discharge pipe for the hydraulic coupler in the structural form has a simple structure, is ingenious in design and reasonable in layout, and is used for solving the problem that the oil discharge pipe used in the traditional hydraulic coupler only can work downwards in a single rotation mode and has limitation; and it still utilizes a protrusion to seal the tail end of oil drain pipe, and the design can be led the medium of oil drain pipe on the one hand like this, and on the other hand still can avoid the medium to get into the tail end of oil drain pipe to the vibration phenomenon that the traditional structure took place because of the medium returns after strikeing oil drain pipe tail end has been eliminated. In conclusion, the bidirectional oil discharge pipe has multiple advantages, is particularly suitable for popularization and application in the field, and has a very wide market prospect.

Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1, 2, and 3: a bidirectional oil drain pipe for a hydraulic coupler comprises a pipe body 1, wherein one end of the pipe body 1 is connected with a pipe orifice 2, a partition plate 3 is arranged in the middle of the pipe orifice 2, the partition plate 3 divides the inside of the pipe orifice 2 into two mutually isolated parts, two liquid inlets 8 are symmetrically formed in the pipe orifice 2, the two liquid inlets 8 are respectively communicated with two cavities in the pipe orifice 2, the partition plate is L1 in length, the pipe orifice 2 is L2 in length, L1 is larger than L2, a semicircular turning plate 4 is hinged to the tail end of the partition plate 3, two limiting blocks which are symmetrically distributed and matched with the turning plate 4 are arranged on the inner wall of the pipe body 1, two symmetrically distributed liquid discharge ports 5 are formed in the pipe body 1, the liquid discharge ports 5 are positioned at the tail end of the partition plate 3, a protrusion 6 is further arranged in the pipe body 1, the protrusion 6 is integrally conical, and the protrusion 6 is positioned at the liquid discharge ports 5, the tail end of the pipe body 1 is provided with a connecting base 7.

The utility model discloses fluid coupling is with two-way oil extraction pipe's working process as follows: as shown in fig. 2, when the medium is rotated counterclockwise, the medium enters the pipe orifice 2 and the upper half chamber of the pipe body 1 from the upper liquid inlet 8 and flows backwards, and when the medium flows onto the tapered protrusion 6, the medium flows radially toward the pipe body 1 under the guiding action of the protrusion and is finally discharged through the liquid discharge port 5 formed on the side wall of the pipe body 1, and in the process, the turning plate 4 naturally turns over under the action of pressure and is clamped on the limit block arranged on the inner wall of the pipe body 1 to close the lower half chamber in the pipe body 1;

similarly, as shown in fig. 3, when the medium is turned to the counterclockwise direction, the medium enters the pipe orifice 2 and the lower half chamber of the pipe body 1 from the liquid inlet 8 below and flows backwards, the medium with a certain pressure pushes the turning plate 4 away, the turning plate 4 turns upwards and is clamped on the limiting block arranged on the inner wall of the pipe body 1 to seal the upper half chamber in the pipe body 1, and when the medium flows onto the tapered protrusion 6, the medium flows radially towards the pipe body 1 under the guiding action of the medium and is finally discharged through the liquid discharge port 5 formed on the side wall of the pipe body 1;

since the rear half of the pipe body 1 is closed by the protrusion 6, the medium cannot enter the rear half of the pipe body 1, so that the vibration phenomenon caused by the medium returning after hitting the tail end of the oil drain pipe can be prevented.
