Abstract
The utility model discloses a protection cover of a common rail tube. The protection cover is characterized in that the protection cover comprises a front shell and a rear shell connected and matched with the front shell. The common rail tube is covered with the front shell and the rear shell. An installing part for installing the common rail tube and a machine body is arranged on the rear shell and provided with an installing hole. A high-pressure oil pipe opening is formed in the connecting face above the front shell and rear shell. The protection cover can serve as an installing support of the common rail tube and can comprehensively protect the common rail tube; in order to increase functions of the protection cover, the front shell is connected with the rear shell in a seal fit mode; the front shell is provided with a liquid level sensor and an oil drain valve and can timely detect oil leakage of the common rail tube so that workers can process oil leakage timely, the liquid level sensor is used for detecting whether oil exists in the protection cover, and the oil drain valve is used for draining oil.
Description
Technical field
The utility model relates to the common rail pipe safety cover of on a kind of motor, common rail pipe being protected.
Background technique
Common rail pipe is a vitals in Electrocontrolled high-pressure common rail motor, that high pressure oil pump is set up the pipeline that after high pressure fuel, fuel pressure is carried out to pressure accumulation and voltage stabilizing, the high-pressure oil pipe being connected with each cylinder is connected with common rail pipe, thereby provide stable high pressure fuel to each cylinder, the quality of common rail pipe directly has influence on the performance of motor, but in the right structure of current motor, not to value very much to the protection of common rail pipe, there is no protective measures, or be a simple protection apron, motor in the course of the work or maintenance, while being subject to extraneous contact in operating process and when External Force Acting, can make common rail pipe produce distortion or damage, cause common rail pipe bad connection, operation irregularity even damages common rail pipe, thereby cause transmitter job insecurity maybe cannot use.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of common rail pipe safety cover that the common rail pipe of motor is protected is provided.
For solving the problems of the technologies described above; the technical solution of the utility model is: a kind of common rail pipe safety cover; comprise interconnective fore shell and back cover; described fore shell and the back cover coated common rail pipe that cooperatively interacts; described back cover is provided with the assembly department that common rail pipe and body are installed; described assembly department is provided with mounting hole, and the junction surface place of described fore shell and back cover top is provided with the high pressure oil mouth of pipe.
Owing to having adopted technique scheme; common rail pipe is arranged on the back cover of safety cover, and back cover is arranged on body, and safety cover can play the effect as common rail pipe mounting bracket; common rail pipe is coated in safety cover simultaneously, and safety cover can be subject to good protection on the whole.
Improve as one, the joint of described fore shell and back cover is sealed and matched, and described fore shell is provided with and detects is in guard shield, whether to have oily liquid level sensor and the fuel outlet valve for oil extraction.Fore shell and back cover are sealed and matched; in the time that appearring in common rail pipe, leakage of oil will accumulate in safety cover; therefore; can perceive in safety cover and whether have oil to conclude whether common rail pipe occurs leaking oil condition by liquid level sensor; once detect that leakage of oil can report to the police at once, make related personnel can obtain in time situation, thereby process in time; prevent larger accident, the fuel oil of leakage can be discharged by fuel outlet valve.
Improve as one, described fore shell and back cover are connected by screw.
Improve as one, the horizontal and vertical stiffening rib that is equipped with of described fore shell and back cover, described installation position is in the intersection of cross reinforcing and the waling of described back cover.Stiffening rib can improve the intensity of housing, protects better common rail pipe, assembly department to be arranged on the intersection of stiffening rib, can guarantee mounting points firm and durable.
Improve as one, described safety cover is provided with one for retraining the pressing plate of high-pressure oil pipe at high pressure oil mouth of pipe place, and described pressing plate is provided with restraining groove.High-pressure oil pipe is connected with the common rail pipe in safety cover through the high pressure oil mouth of pipe; because the high pressure oil mouth of pipe of fore shell and the formation of back cover joint is conventionally large than the diameter of high-pressure oil pipe; the constraint of the position at the high pressure oil mouth of pipe to high-pressure oil pipe is limited; therefore the pressing plate of constraint high-pressure oil pipe is set; restraining groove coordinates the position of high-pressure oil pipe is blocked with the high pressure oil mouth of pipe, can prevent that pipeline position is mixed and disorderly.
Improve as one, the blank of described fore shell and the blank of back cover are general.Like this rough-cast of fore shell and back cover out after, both can be processed into fore shell, also can be processed into back cover, in casting and follow-up processing, all facilitate.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model embodiment's structural representation;
Fig. 2 is the rear view of Fig. 1;
Fig. 3 is the plan view of Fig. 1;
In figure: 1, fore shell; 2, fuel outlet valve; 3, liquid level sensor; 4, screw; 5, common rail pipe; 6, pressing plate; 61, restraining groove; 7, back cover; 8, assembly department; 9, mounting hole; 10, the high pressure oil mouth of pipe.
Embodiment
As Fig. 1, shown in Fig. 2 and Fig. 3 are common, a kind of common rail pipe safety cover, comprise interconnective fore shell 1 and back cover 7, described fore shell 1 is connected by screw 4 with back cover 7, described fore shell 1 and back cover 7 cooperatively interact and are coated common rail pipe 5, the joint of described fore shell 1 and back cover 7 is sealed and matched, conventionally one end of common rail pipe needs connection data line, therefore this one end need to be stretched out outside safety cover, between this one end and safety cover, be also sealed and matched, described fore shell 1 is provided with to detect in safety cover whether have oily liquid level sensor 3 and the fuel outlet valve 2 for oil extraction, described back cover 7 is provided with the assembly department 8 that common rail pipe 5 and body are installed, described assembly department 8 is provided with mounting hole 9, general common rail pipe itself is all with mounting hole 9, therefore pass the mounting hole 9 on mounting hole 9 and the assembly department 8 of common rail pipe 5 by bolt, finally bolt is being installed on body, common rail pipe 5 and back cover 7 have just been fixed on body like this, in the time that safety cover is installed on body, the position of liquid level sensor 3 and draining valve should be located substantially on the below of horizontal position, once common rail pipe 5 leakage of oils, just can find in time, and facilitate fuel outlet valve 2 that oil is all discharged, the junction surface place of described fore shell 1 and back cover 7 tops is provided with the high pressure oil mouth of pipe 10, high-pressure oil pipe is entered in safety cover and is connected with common rail pipe 5 by the high pressure oil mouth of pipe 10, because the bore of the high pressure oil mouth of pipe 10 is conventionally all much larger than the diameter of high-pressure oil pipe, therefore, safety cover is provided with one for retraining the pressing plate 6 of high-pressure oil pipe at the high pressure oil mouth of pipe 10 places, described pressing plate 6 is provided with restraining groove 61, restraining groove 61 is used for blocking the position of high-pressure oil pipe, make the position stability of high-pressure oil pipe.
For convenience of manufacturing, the blank of described fore shell 1 and back cover 7 adopt general blank, and blank both can be processed as fore shell 1, also can be processed as back cover 7, bring great convenience to casting and processing.
