Abstract
Comparing with the prior art, there is no self-contained cylinder liner in the invented electric hydraulic pusher. That is to say the cylinder liner is combined with the cylinder body as a whole. Thus, the producing procedure is simplified by castform at one time so as to save material, raise yield and lower cost. Hydraulic oil can be circulated through the oil storage cavity without affecting the use effect.
Description
Technical field
The present invention relates to a kind of electro hydraulicthruster, it is made up of motor that is arranged on pusher one end and the plunger that is arranged in the same clutch release slave cylinder with the fuel pump impeller of motor coaxle rotation, with fuel pump impeller, is mainly used in the open a sluice gate drive unit of departments such as metallurgy, mine, harbour as block brake.
Technical background
Electro hydraulicthruster is the driving element of block brake, and the existing power hydraulic driver comprises upper and lower two housings as shown in Figure 1, and motor is set in the lower shell body; Lower half portion of upper shell is the impeller storehouse, wherein be provided with the impeller that is installed on the motor shaft, upper half part is a plunger mechanism, comprise piston that is connected on the push rod and the cylinder sleeve that cooperates with piston, cylinder sleeve is connected with housing by being arranged on its peripheral muscle, like this, between housing and cylinder sleeve, just formed an asphalt channel, during reciprocating motion of the pistons, hydraulic oil flows back and forth by this asphalt channel, simultaneously by the housing distribute heat.The electro hydraulicthruster housing difficulty of processing of this structure is big, complex process, cost of production height.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, processing technology is simple, cost of production is low electro hydraulicthruster.
For achieving the above object, the present invention adopts following technological scheme:
Electro hydraulicthruster of the present invention comprises motor casing, be arranged on the motor in the motor casing, oil hydraulic cylinder, be arranged on the fuel pump impeller in the oil hydraulic cylinder, and be arranged on plunger mechanism in the same oil hydraulic cylinder with fuel pump impeller, oil hydraulic cylinder can be divided into the impeller storehouse of bottom and the working bin on top again, fuel pump impeller is arranged in the impeller storehouse of cylinder lower, plunger mechanism is arranged in the working bin on oil hydraulic cylinder top, one side of hydraulic cylinder body is provided with the reservoir compartment, plunger mechanism comprises piston that is connected on the push rod and the cylinder sleeve that cooperates with it, cylinder sleeve and hydraulic cylinder body are combined into one, the lower end of reservoir compartment communicates with the impeller storehouse, and the upper end communicates with the working room on cylinder sleeve top.
Cylinder sleeve and hydraulic cylinder body are combined into one, can the one-step casting moulding in casting process, simple in structure, save material, production technology is simplified greatly, improved the up-to-standard rate of product, can reduce production costs effectively, and hydraulic oil still can produce circulation by the reservoir compartment, does not influence using effect.
Description of drawings
Fig. 1 is an embodiment's of background technique a half sectional view;
Fig. 2 is the half sectional view of one embodiment of the present of invention;
Fig. 3 is the oil hydraulic cylinder worm's eye view among Fig. 2.
Embodiment
As Fig. 2, shown in Figure 3, electro hydraulicthruster of the present invention comprises two housings up and down that link together by bolt, and lower shell body is a motor casing, and motor 1 is arranged in the motor casing; Upper shell is an oil hydraulic cylinder, and oil hydraulic cylinder can be divided into two storehouses up and down, and the bottom is the impeller storehouse near motor casing, and the fuel pump impeller 2 that is installed on the motor 1 is located in the impeller storehouse.Be working bin above the impeller storehouse, plunger mechanism is arranged in the working bin on oil hydraulic cylinder top, piston 7 is arranged in working bin, unlike the prior art be: cylinder sleeve independently not in the working bin of electro hydraulicthruster of the present invention, piston 7 directly cooperates with hydraulic cylinder body, that is: cylinder sleeve 5 is combined into one with hydraulic cylinder body 6.One side of hydraulic cylinder body 6 is provided with reservoir compartment 3 equally, and the lower end of reservoir compartment 3 communicates with the impeller storehouse, and the upper end communicates with the working room on cylinder sleeve 5 tops.
