Detailed Description

The objects, technical solutions and advantages of the present utility model will become more apparent by the following detailed description of the present utility model with reference to the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.

The specific embodiment is as follows: referring to fig. 1 to 3, the device comprises a body 1; and a detachable detection mechanism installed at one side of the lower part of the machine; the detachable detection mechanism comprises an L-shaped pipe fitting 2 and a joint 3 for connecting the L-shaped pipe fitting 2 with the body 1; the L-shaped pipe fitting 2 comprises an oil containing cavity 4, a transition cavity 5 and a push-back cavity 6 which are sequentially arranged from bottom to top; a baffle 7 is arranged between the upper part of the oil containing cavity 4 and the transition cavity 5; the baffle 7 is provided with a first through hole 8 for communicating the oil containing cavity 4 and the transition cavity 5; a sealing ball 9 is arranged in the transition cavity 5; the upper part in the transition cavity 5 is provided with a second through hole 10 for communicating the transition cavity 5 and the push-back cavity 6; a push plate 11 is arranged in the push-back cavity 6; the push plate 11 extends to the outer side of the pipe fitting through a rod 12 and is provided with a push-pull sheet 13; a first contrast plate 14 and a second contrast plate 15 are arranged on two sides of the outer wall of the L-shaped pipe fitting 2 at the corresponding position of the oil accommodating cavity 4; the upper side wall in the transition cavity 5 is obliquely arranged around the second through hole 10; the second through hole 10 corresponds to the sealing ball 9 in size; the baffle 7 is provided with a plurality of first through holes 8.

When the L-shaped pipe fitting 2 needs to be detached, the L-shaped pipe fitting 2 is detachably mounted on the body 1 through the joint 3, the L-shaped pipe fitting 2 is detached through the rotary joint 3, and bolts are mounted at the detaching positions, so that the sealing of the body 1 can be completed.

When the L-shaped pipe fitting 2 is required to be installed, the position where the bolts are originally installed is taken down through the fitting, and then the L-shaped pipe fitting 2 is installed at the corresponding position of the body 1 through the joint 3, as shown in FIGS. 1-3.

When the L-shaped pipe fitting 2 is used for detecting the working state of lubricating oil in the gear box, as shown in the figures 1-3, firstly, the L-shaped pipe fitting 2 is installed on the gear box, then the screw on the upper side of the gear box is taken down, at the moment, air is introduced into the gear box, the lubricating oil more easily enters the oil accommodating cavity 4 of the L-shaped pipe fitting 2, the push-pull piece 13 can be pulled upwards downwards to accelerate the speed of the lubricating oil entering the oil accommodating cavity 4, the inner wall of the oil accommodating cavity 4 of the L-shaped pipe fitting 2 is made of transparent materials, after the lubricating oil fills the oil accommodating cavity 4, the lubricating oil enters the transition cavity 5 along the first through hole 8, and at the moment, the sealing ball 9 in the transition cavity 5 is jacked up; the density of the sealing ball 9 is smaller than that of lubricating oil, so that the sealing ball 9 floats in the transition cavity 5, the side wall of the transition cavity 5 is set to shrink and incline to the middle, the sealing ball 9 can only float to the second through hole 10 in the middle due to limiting, when the sealing ball 9 floats to the second through hole 10, the second through hole 10 is blocked, lubricating oil can not continuously float, at the moment, the state of the lubricating oil in the oil containing cavity 4 can be stable or directly observed, the first contrast plates 14 and the second contrast plates 15 on two sides of the oil containing cavity 4 are respectively stuck with colors corresponding to different use states of the lubricating oil, particularly, the colors can be freely set, for example, the first contrast plates 14 are stuck with good-state lubricating oil colors, the second contrast plates 15 are stuck with poor-state lubricating oil colors when the replacement is needed, and constructors can determine whether the lubricating oil needs to be replaced at the moment through standing or directly comparing the states of the lubricating oil colors. When the L-shaped pipe fitting 2 needs to be replaced, the oil is discharged and injected. When the replacement is not needed, the push plate 11 is pushed to move downwards along the push-back cavity 6 by downwards extruding the push-pull sheet 13 through the rod 12, so that air enters the transition cavity 5 along the second through hole 10, enters the oil containing cavity 4 along the first through hole 8, and then lubricating oil in the oil containing cavity 4 flows back into the body 1 through the joint 3, and the waste of the lubricating oil is avoided.
