Abstract

The utility model relates to a lightweight type electric and manual oil pump, which comprises a motor, a transmission mechanism, an oil tank, and a plunger pump. The utility model is characterized in that an output shaft of the motor is connected with an input shaft of the transmission mechanism by a shaft coupling; the speed of the power output by the motor is reduced by the transmission mechanism, and the power is output by a cam mechanism in a 90 DEG; a plunger rod of the plunger pump is arranged on the lower part of the cam mechanism; the outlet end of the plunger pump is provided with an oil in-and-out control valve; the other end of the input shaft of the transmission mechanism is the connecting end of a handle; the motor, the transmission mechanism, the oil tank, and the plunger pump are connected with each other to form an integral body. Because the utility model adopts that the transmission mechanism, an oil pump, the oil tank, and the control valve form an integral body, the utility model has the advantages of small volume, light weight, and compact structure. Because the utility model can be operated by hand and electricity, the utility model is more convenient and practical.

Description

Handy type electric and manual oil pump

Technical field

The utility model relates to hydraulic jacking device, specifically is a kind of heavy automobile cab handy type electric and manual oil pump of elevate a turnable ladder forward that is applicable to.

Technical background

At present, the motor of of home make tack heavy-duty car break down maybe will maintain the time all must with operator cabin forward lifting it is flipped an angle.Wherein the tack heavy-duty car more than 90% still turns over the operator cabin lifting by manpower, the labor intensity that this just must be bigger, and a people can't finish lifting upset work at all sometimes.Break down and have only and just can not handle timely and effectively under driver one people's the situation at the countryside motor, this brings certain loss just for transporter and recipient.Though the heavy-duty car (as the red rock automobile) that minority is arranged can be finished a people and is driven lifting upset work at hand oil pump of original base equipment, exists labor intensity big, ineffective deficiency.Also there is few heavy vapour truncate car to be equipped with electric oil pump, but, when motor produces fault, just can't uses owing to no hand pump.In order to overcome this problem, existing electronic in the prior art, manually be split type oil pump, not to have the function defectiveness, be exactly weight is bigger than normal greatly for volume.

The content of invention

Technological scheme to be solved in the utility model is: provide a kind of both can be electronic, manual again, the handy type electric and manual oil pump of structure one.

The technical solution adopted in the utility model is such, and promptly a kind of handy type electric and manual oil pump comprises motor, driving mechanism, fuel tank and plunger pump; It is characterized in that: the output shaft of motor is connected with the input shaft of driving mechanism by coupling, driving mechanism is with the dynamic retarding of motor output and be 90 ° and exported by cam mechanism, the plunger rod of plunger pump is positioned at the below of cam mechanism, and the outlet end of plunger pump has the turnover oil control valve; The other end of the input shaft of driving mechanism is the handle connecting end; Described motor, driving mechanism, fuel tank and plunger pump are connected to integral body.

The utility model adopts vertical single plunger pump, because with driving mechanism, oil pump, fuel tank and control valve are formed one.Make volume little in light weight, structure is tightly played, owing to adopt alloy aluminum housing heat radiation energy strong, critical piece adopts superior alloy steel, and advanced heat treatment process is durable in use, machining accuracy height, volumetric efficiency advantages of higher.

Description of drawings

The utility model has following accompanying drawing:

Accompanying drawing 1 is a generalized section of the present utility model;

Accompanying drawing 2 is that the A of accompanying drawing 1 is to generalized section.

Referring to accompanying drawing: 1-pump valve body, 2-valve reversing shaft, 3-mangetic core assembly, 4-plunger bushing, 5-casing, 6-plunger rod, 7-bearing bracket, 8-worm gear, 9-copper sheathing, 10-worm-wheel shaft, 11-cam, 12-axle sleeve, 13-adjust locating flange, the little flange of 14-, 15-direct current generator, 16-coupling, 17-coupled axle-pin, 18-worm shaft, 19-filter screen, 20-handle, 21-oil sealing nut and oil scale, 22-manual handle connecting end among the figure.

Embodiment

Mechanism of the present utility model can further specify by the embodiment that valve body provides.

Referring to accompanying drawing: the driving mechanism of the handy type electric and manual oil pump among the figure comprises worm shaft (18), worm gear (8) and cam (11), wherein worm-wheel shaft is a power input shaft, the one end is connected with machine shaft by coupling (16), and the other end is the manual handle connecting end; Coaxial fixing with the worm gear of worm meshing with cam.

Driving mechanism also can adopt gear train and cam to constitute.

Have bearing bracket (7) on the plunger rod of plunger pump (6), the cam of its top contacts with the bearing of support upper support in rotary course and makes the downward moving linearly of plunger rod, and plunger rod is resetted by the Returnning spring that is installed in plunger bushing (4).

The outlet end of plunger pump has the turnover oil control valve that is made of mangetic core assembly (3), valve reversing shaft (2) below plunger rod; Wherein mangetic core assembly has the oily passage of turnover, and oil discharge passage is unidirectional conducting; Valve reversing shaft (2) is by the switching of the turnover oil passage of Spin Control mangetic core assembly, and the one end connects transfer handle (20).Filler opening at fuel tank goes out to have filter screen.

The working principle of the utility model said structure is such: the motor rotation is passed to worm screw by coupling with power, worm screw with power pass to worm gear slow down and 90 ° of commutations after power is passed to cam, cam is passed to bearing on the bearing bracket with power, bearing bracket and plunger rod are interference fit, plunger rod and cylinder gap cooperate, become the straight line motion of circular movement by cam into plunger rod, bearing bracket and plunger rod, under the effect of cam and spring, linear reciprocating motion in plunger bushing, form volume-variation, when plunger rod moves upward, the plunger bushing internal volume increases, and hydraulic oil is crossed filler opening and entered in the oil pump plunger motion from the top down more at this moment under the atmospheric pressure effect, make high pressure oil enter control valve, be transported to external hydraulic lifting mechanism by oil outlet.

The utility model is because described structure, when needing repairing or maintain motor, need only press the button switch and make machine operation, in clock, just the operator cabin lifting can be turned to desired location at 1 minute, when the electronic situation that breaks down, just can finish above-mentioned work by connecting hand arm at manual handle connecting end (22).
