[technical field]
The present invention relates to weight-lifting equipment, in particular, the present invention relates to a kind of electric hydaulic lifting machine.
[background technology]
Jack is that part is lifted as equipment, the light little weight-lifting equipment of jacking weight in stroke by top bracket or bottom claw in one rigidity top.Rack-jack, lifting screw and hydraulic jack 3 kinds can be divided into by architectural feature.Jack is the simplest weight-lifting equipment of a kind of lifting highly little (being less than 1m).It has mechanical type and fluid pressure type two kinds.Mechanical jack has again rack-and-pinion and spiral two kinds, because hoisting capacity is little, operation effort, general only for flight-line maintenance work, repair in bridge process inapplicable.Hydraulic jack compact conformation, stable working, has self-locking action, therefore uses extensively.Its shortcoming is lifting limited height, and lifting velocity is slow, and safety factor is little.
[summary of the invention]
The object of the invention is to the deficiency effectively overcoming above-mentioned technology, the electric hydaulic lifting machine that a kind of lifting velocity is fast, safety factor is high, work efficiency is high is provided.
Technical scheme of the present invention is achieved in that it includes a traversing carriage, this traversing carriage has platform, its improvements are: described platform is provided with power plant, lift oil tank and one engine, described one engine includes belt pulley, strand oil pump and petrol storage tank, described strand oil pump to be connected in petrol storage tank and to be arranged on below petrol storage tank, described belt pulley is arranged on strand oil pump, and is provided with a belt between belt pulley and the output shaft of power plant; Described strand oil pump has and oil outlet, and this oil outlet is connected to the oil inlet of lift oil tank by oil pipe;
In above-mentioned structure, described platform end is provided with the oil cylinder seat of a tubbiness, and this oil cylinder seat is for placing lift oil tank;
In above-mentioned structure, described power plant is three-phase motor, and platform is also provided with a source switch, and this source switch is arranged between civil power mouth and the power pack of three-phase motor, for controlling the power on/off of three-phase motor;
In above-mentioned structure, be provided with one wheel pairs below described traversing carriage, this traversing carriage front end is provided with a bracing frame;
In above-mentioned structure, one end of described traversing carriage is provided with the pushing hands of an inclination, is convenient to the movement of this traversing carriage;
In above-mentioned structure, the side of described strand oil pump is provided with a compression relief cock.
Beneficial effect of the present invention is: the present invention provides power by three-phase motor, and by the combined action of belt and belt pulley, drive the strand oil pump running of one engine, hydraulic oil in petrol storage tank is sent in lift oil tank by strand oil pump, promote to hoist the extension bar of cylinder, and then promote the object being positioned at lift oil tank top, this kind of electric hydaulic lifting machine of the present invention, its lifting velocity is fast, safety factor is high, work efficiency is high, and its work efficiency is 50 times of old-fashioned jack.
[accompanying drawing explanation]
Fig. 1 is front view of the present invention;
Fig. 2 is back view of the present invention.
[detailed description of the invention]
Below in conjunction with drawings and Examples, the invention will be further described.
With reference to shown in Fig. 1, present invention is disclosed a kind of electric hydaulic lifting machine, this electric hydaulic lifting machine is used for jack-up weight, to be mainly applicable to before and after various replacing vehicle bow etc., can to replace traditional old-fashioned jack.Electric hydaulic lifting machine of the present invention has a traversing carriage 10, one wheel pairs 101 is provided with below this traversing carriage 10, be convenient to the movement of electric hydaulic lifting machine, traversing carriage 10 front end is provided with a bracing frame 102, this bracing frame 102 be convenient to electric hydaulic lifting machine under static state time keep balance, in addition, one end of traversing carriage 10 is provided with the pushing hands 103 of an inclination, when electric hydaulic lifting machine needs mobile, just very convenient in the movement of electric hydaulic lifting machine by pushing hands 103.
Traversing carriage 10 has platform 104, platform 104 is provided with power plant, lift oil tank 20 and one engine 30, this power plant is a three-phase motor 40 in the present embodiment, one engine 30 includes belt pulley 301, strand oil pump 302 and petrol storage tank 303, strand oil pump 302 to be connected in petrol storage tank 303 and to be arranged on below petrol storage tank 303, belt pulley 301 is arranged on strand oil pump 302, in addition, overlap between the output shaft of belt pulley 301 and three-phase motor 40 and have a belt 50, by the rotation of three-phase motor 40, belt pulley 301 is driven to rotate, and then impel strand oil pump 302 to work, strand oil pump 302 has oil outlet 3020, this oil outlet 3020 is connected to the oil inlet 201 of lift oil tank 20 by oil pipe, oil pipe is embodied in the present embodiment.In addition, platform 104 is also provided with source switch 60, this source switch 60 is arranged between the power pack 401 of civil power mouth and three-phase motor 40, for controlling the power on/off of three-phase motor 40, can find out at Fig. 2 of the present embodiment, be connected by wire 601 between source switch 60 with power pack 401.By above-mentioned structure, after turning on the power switch 60, the rotation of three-phase motor 40 drives belt pulley 301 to rotate, and then impel strand oil pump 302 to work, hydraulic oil in petrol storage tank 303 is sent in lift oil tank 20 by strand oil pump 302, the extension bar 202 of lift oil tank 20 is that is protruding, by the object jack-up above lift oil tank 20; The side of strand oil pump is provided with a compression relief cock 3021, and when needs unload lift oil tank 20, press compression relief cock 3021, the hydraulic oil of lift oil tank 20 inside is then back in petrol storage tank 303, and namely extension bar 202 retracts, and completes uninstall process.This kind of electric hydaulic lifting machine of the present invention, its lifting velocity is fast, safety factor is high, work efficiency is high, and its work efficiency is 50 times of old-fashioned jack.
