The utility model aims to solve the technical problem of the prior art after the pressure of a ladle hydraulic cylinder is built, and provides a pressure relief device of the ladle hydraulic cylinder.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
the utility model provides a ladle pneumatic cylinder pressure release device, includes the handle, and the one end of handle is fixed with keeps off the oil cover, keeps off the one end that the oil cover is close to the handle and seals, and the other end that keeps off the oil cover is the open end, keeps off oil cover internal fixation and is equipped with the drain body, and keeps off and be equipped with the clearance between the lateral part of oil cover and drain body, the drain body and the public first looks adaptation of hydraulic pressure station quick-operation joint.
Further, the upper portion of the oil drain body is provided with a butt joint end, a cavity is arranged in the butt joint end, and a thimble is arranged in the middle of the cavity.
Further, 1/3 section of the oil shield close to the opening end of the handle is cylindrical, and the other section of the oil shield is horn-shaped.
Further, the handle and the oil shield are both made of steel pipes with the wall thickness of 3-5 mm.
Compared with the prior art, the utility model has the following beneficial effects:
the utility model has the advantages of safe manufacture, simple and efficient use and long-term use. After the device is used, the problem that the normal casting of the continuous casting machine is interrupted because the hydraulic cylinder cannot be timely decompressed after the hydraulic cylinder of the steel ladle is pressurized can be well avoided, the normal continuous casting of the continuous casting machine is ensured, and the device can be used for many times for a long time.
According to the utility model, the oil blocking cover of the horn is arranged, and when hydraulic oil in the hydraulic cylinder flows into the oil blocking cover and then flows out from the horn mouth of the oil blocking cover, high-temperature hydraulic oil is prevented from splashing on a person.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
The reference numerals have the following meanings: 1. a handle; 2. an oil shield; 3. an oil drain body; 4. a cavity; 5. a thimble; 6. a butt joint end; 7. an open end.
Detailed Description
The utility model is further described below with reference to the drawings and the detailed description.
As shown in fig. 1, the pressure relief device of the ladle hydraulic cylinder comprises a handle 1, wherein one end of the handle 1 is fixedly welded with an oil blocking cover 2, one end of the oil blocking cover 2, which is close to the handle 1, is closed, the other end of the oil blocking cover 2 is an open end 7, a 7 1/3 section of the oil blocking cover 2, which is close to the open end of the handle 1, is cylindrical, and the other section of the oil blocking cover 2 is horn-shaped. The oil drainage body 3 is fixedly welded in the oil shielding cover 2, a gap is formed between the oil shielding cover 2 and the side part of the oil drainage body 3, the oil drainage body 3 is matched with a male head of a quick connector of a hydraulic station, a butt joint end 6 is arranged on the upper part of the oil drainage body 3, a cavity 4 is formed in the butt joint end 6, and a thimble 5 is arranged in the middle of the cavity 4.
The handle 1 and the oil shield 2 are both made of steel pipes with the wall thickness of 3-5 mm.
In the embodiment, the handle 1 is a steel pipe with the outer diameter phi 17mm, the wall thickness is 3mm, the length is 340mm, the oil drain body 2 is welded and connected with the handle 1, the oil shield 3 is a steel pipe with the outer diameter phi 30mm, the wall thickness is 3mm, the length is 120mm, one end of the oil shield 3 is processed into a horn shape, and the outer diameter phi of a horn mouth is 60mm.
The application process of the utility model is as follows:
the first step: when the ladle hydraulic cylinder is pressed out and the quick connector female head of the ladle hydraulic station cannot be connected in the continuous casting ladle pouring process, the device is used for aligning the device oil drain body 3 to the quick connector male head of the ladle hydraulic cylinder.
And a second step of: the end of the handle 1 of the hand hammer knocking device is used, an oil path channel is opened after a thimble in a steel ladle hydraulic cylinder is extruded, hydraulic oil in the hydraulic cylinder flows into the oil baffle cover 2 through a quick connector male head, and then flows out of a bell mouth of the oil baffle cover 2.
