Abstract

The utility model relates to a safety protection device preventing leakage of a hydraulic oil of an engineering vehicle. The safety protection device comprises a hydraulic oil tank with a tank opening at the top. The hydraulic oil tank is connected with a hydraulic pump and an engine of a power system. The safety protection device is characterized in that a liquid level sensing device is suspended on an oil level in the hydraulic oil tank; the liquid level sensing device is connected with a contact switch which is connected with a signal feedback device; a sliding sleeve is arranged at the tank opening of the hydraulic oil tank and is fixedly connected with an end cover of the tank opening. The safety protection device preventing leakage of the hydraulic oil of the engineering vehicle provided by the utility model is simple in structure, convenient to install and use, and stable and reliable in performance. When the hydraulic oil leaks, the device can control a power source of the hydraulic system immediately so that the hydraulic system stops working, thereby effectively inhibiting or relieving continuous loss of oils.

Description

The safety protection device of prevention engineering vehicle hydraulic fluid leak
Technical field
The utility model belongs to the technical field of mine engineering vehicle hydraulic oil anti-leak, relates in particular to a kind of safety protection device that prevents the engineering vehicle hydraulic fluid leak.
Background technique
The hopper lifting of engineering vehicle and the action of deflecting roller deflection generally all are to lean on HYDRAULIC CONTROL SYSTEM, and hydraulic control system all plays crucial effects for the working stability and the riding stability of engineering vehicle.Hydraulic system of engineering vehicle leans on engine drives oil hydraulic pump control hydraulic actuator to convert the pressure of liquid to mechanical energy, in order to the lifting of Control Engineering vehicle hopper and the deflection action of deflecting roller when proper functioning.Engineering vehicle is when work; If hydraulic system generation conduit failure or oil sealing leakage can directly cause the fluid in the hydraulic oil container to leak; Fluid leaks and not only causes waste; The fluid that leaks also can cause other hydraulic element to damage, even security incident takes place, so in time shutdown inspection is also handled.
Summary of the invention
The purpose of the utility model realizes through following technical proposals:
A kind of safety protection device that prevents the engineering vehicle hydraulic fluid leak of the utility model; Comprise that the top has the hydraulic oil container of case mouth, this hydraulic oil container is connected with motor with the power system oil hydraulic pump, it is characterized in that being suspended with liquid level induction system on the pasta in the described hydraulic oil container; This liquid level induction system is connected with contact switch; This contact switch is connected with signal feedback device, is provided with sliding sleeve at the case mouth place of described hydraulic oil container, and this sliding sleeve is fixedly connected with case mouth end cap.
Described liquid level induction system is by being suspended in the float on the pasta in the hydraulic oil container; Therewith the float lever that is threaded of float and therewith the adjusting nut that is threaded of float lever lower end form; Described float lever and described sliding sleeve are slidingly connected, and the upper end of described float lever is connected with described contact switch.
Described contact switch is by the fixedly double-contact that is located at case mouth end caps; The fixing corresponding mobile contact base of double-contact therewith; Upper spring and lower spring that mobile therewith respectively contact base upper and lower is connected are formed; Described upper spring is connected with described case mouth end cap, and the upper end of described lower spring and described float lever socket-connects.
Described signal feedback device comprises the one group of lead that is connected with described fixedly double-contact, organizes fuel solenoid valve and storage battery that lead is connected respectively therewith.
The advantage of the utility model:
The utility model is simple in structure, and is easy to install, stable and reliable for performance, and when hydraulic oil leaked, this device is the power source of controlled hydraulic system in time, and hydraulic system is quit work, and effectively prevents or alleviates oil product and continue to run off.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Embodiment below in conjunction with description of drawings the utility model.
As shown in Figure 1; A kind of safety protection device that prevents the engineering vehicle hydraulic fluid leak; Comprise that the top has the hydraulic oil container 1 of case mouth, this hydraulic oil container 1 is connected with motor with the power system oil hydraulic pump, it is characterized in that being suspended with liquid level induction system on the pasta in the described hydraulic oil container 1; This liquid level induction system is connected with contact switch; This contact switch is connected with signal feedback device, is provided with sliding sleeve 5 at the case mouth place of described hydraulic oil container 1, and this sliding sleeve 5 is fixedly connected with case mouth end cap 9.
Described liquid level induction system is by being suspended in the float 2 on the pasta in the hydraulic oil container 1; The float lever 4 that is threaded of float 2 and 3 compositions of adjusting nut of being threaded of float lever 4 lower ends therewith therewith; Described float lever 4 is slidingly connected with described sliding sleeve 5, and the upper end of described float lever 4 is connected with described contact switch.
Described contact switch is by the fixedly double-contact 10 that is located at case mouth end caps; Fixing double-contact 10 corresponding mobile contact bases 7 therewith; Move the upper spring 8 and 6 compositions of lower spring that contact base 7 upper and lowers are connected respectively therewith; Described upper spring 8 is connected with described case mouth end cap 9, and described lower spring 6 socket-connects with the upper end of described float lever 4.When contact switch was connected, fixed contact 10 was abutted against with mobile contact base 7 mutually, and this moment, upper spring 8 was compressive state, in case leakage of oil takes place, upper spring 8 flicks, and moved contact base 7 and separated with fixed contact 10, and contact switch breaks off.
Described signal feedback device comprises the one group of lead 13 that is connected with described fixedly double-contact 10, organizes fuel solenoid valve 12 and storage battery 11 that lead 13 is connected respectively therewith.Fuel solenoid valve 12 is connected with motor, can directly switch on or off the fuel gallery of motor, the open and close of control motor.
Hydraulic system of engineering vehicle leans on the engine drives oil hydraulic pump to provide power to convert the pressure of liquid to mechanical energy when proper functioning.During ato unit, fuel solenoid valve 12 paths, adjustment adjusting nut 3 and upper spring 8 make float 2 be in the oil level normal place, and this moment, contact switch was connected, the hydraulic system normal operation.When generation fluid leaked in the hydraulic system, the liquid level of fuel tank inner fluid began to descend, and float 2 also descends thereupon, and float lever 4 descends with float 2, and this moment, spring 8 flicked, and mobile contact base 7 separates with fixed contact 10, and contact switch breaks off.Contact switch breaks off and directly causes the signal feedback device open circuit; Cause fuel solenoid valve 13 open circuit wherein, cut off and be the fuel gallery of engine oil, tail-off stops working; Oil hydraulic pump quits work; The hydraulic system leakage of oil is stopped or slowing down, in time check and overhaul, prevent that effectively the hydraulic oil in the hydraulic system from continuing to leak.
