Abstract
The utility model discloses an automatic portable jack used for maintaining a moving heavy operation vehicle, which is composed of an outer shell 1, a motor 2, a coupling 3, a lead screw 4 inside the coupling 3, a nut 5, a cylinder 6, a piston 7 inside the cylinder 6, a piston 8, a support bar 9, a cushion sleeve 10, a travel switch 11 and an operating keyboard 12. The height of the jack is firstly adjusted on the operating keyboard 12, and then an ascending button or a descending button is pressed, thus the motor 2 drives the nut 5 to rotate by means of the coupling 3, and drives the lead screw 4 and drives the piston 7 and the piston 8 to move, all of which make the support bar 9 inside the cylinder 6 move so as to jack up or lower the vehicle and the actions of jacking up or lowering the vehicle will be stopped until the vehicle reaches the required height and knocks on the travel switch 11.The utility model transfers the power according to the hydraulic transmission principle, and designs the controlled circuit to finish the automatic control by means of an automatic controlling circuit, and avoids the disadvantages that the manual driven and foot trod jacks are strenuous and lift blindly. With a beautiful appearance, compact structure and convenient carrying, the utility model is applied in the temperatures of minus 20 centigrade to plus 45 centigrade and can hoist the height of 150 mm and the weight of five tons.
Description
(1) technical field:
The utility model relates to a kind of jack, is mainly used in the maintenance of flowing power heavy work self-propelled vehicle (as automobile, trac. etc.), can automatically self-propelled vehicle be lifted and be raised to require height, thereby finish lifting work.
(2) background technology:
The self-propelled vehicle of flowing power heavy work (as automobile, trac. etc.) often will be propped up it and be raised to certain altitude and keep in repair as breaking down, and this just need use jack.The jack that uses in the self-propelled vehicle maintenance unit at present all is artificial shaking, pedal operation, and the general volume of these products is bigger, complex structure, and operation is hard, brings very big inconvenience to the maintainer, also is not easy to fast lifting simultaneously.
(3) innovation and creation content:
The purpose of this utility model provides a kind of automatic portable vehicle jack, and it can alleviate people's labour intensity, increases work efficiency, and is specially adapted to the interim maintenance of the self-propelled vehicle of field work.
For solving above-mentioned task, the solution that the utility model adopts is: a kind of automatic portable vehicle jack, it is characterized in that: it is made up of shell, motor, coupler and interior screw mandrel, nut, oil cylinder and interior piston, piston, strut bar, cushion cover, travel switch and operation keyboard thereof thereof, wherein, motor is connected with nut through coupler, nut and screw mandrel link, and an end of screw mandrel is a piston, and an end of strut bar is a piston for the cushion cover other end.
With the vehicular power-bottle power supply of self-propelled vehicle as propulsion source, press the hydraulic transmission principle transferring power, finish automatic guidance by automatic control circuit design control circuit, lift self-propelled vehicle and reach desired adjustable height, thereby avoided the shortcoming of shaking and pedal jack effort and lifting blindness, increased work efficiency.
The utility model adopts the self-propelled vehicle battery power as propulsion source, only need pick out two power leads on storage battery, and is very convenient.Because therefore compact conformation is suitable for carrying, on principle, adopt the hydrostatic drive function of increasing pressure, have the labour-saving characteristics.The utility model is suitable for upright use, and Applicable temperature is-20 ℃～+ 45 ℃, only is not suitable for using in the occasion of soda acid and aggressive fume.Lifting highly is 150mm, and lifting weight is 5 tons.
(4) drawing explanation:
Fig. 1 is a constructional drawing of the present utility model;
Fig. 2 is an External view of the present utility model.
(5) specific embodiment:
Physical construction of the present utility model is made up of shell 1, motor 2, coupler 3 and interior screw mandrel 4, nut 5, oil cylinder 6 and interior piston 7, piston 8, strut bar 9, cushion cover 10, travel switch 11 and operation keyboard 12 thereof thereof.The automatic guidance part is made up of travel switch 11 and operation keyboard 12, wherein, motor (2) is connected with nut (5) through coupler (3), and nut (5) links with screw mandrel (4), one end of screw mandrel (4) is piston (7), and an end of strut bar (9) is that cushion cover (10) other end is piston (8).On operation keyboard 12, adjust height in advance, when the lifting key of push keyboard 12, motor 2 drives nut 5 by coupler 3 and rotates, the screw mandrel 4 drive pistons 7 that promote in the coupler 3 move forward, piston 8 moves up, thereby make strut bars 9 in the oil cylinder 6 jack-up self-propelled vehicle that moves up, when arriving the requirement height that operation keyboard 12 adjusts in advance, knock travel switch 11 and stop; If during the decline knob of push keyboard 12, electrical motor 2 counter-rotatings descend self-propelled vehicle.If highly improper behind the jack-up self-propelled vehicle, can on operation keyboard 12, suitably adjust height up and down, press rising or decline button on the operation keyboard 12 then, to reach suitable height.Cushion cover 10 is used to protect strut bar 9 and shell 1, and shell 1 makes the utility model aesthetic in appearance, and easy to carry.
Claims (2)
1. automatic portable vehicle jack, it is characterized in that: it is made up of shell (1), motor (2), coupler (3) and interior screw mandrel (4), nut (5), oil cylinder (6) and interior piston (7), piston (8), strut bar (9), cushion cover (10), travel switch (11) and operation keyboard (12) thereof thereof, wherein, motor (2) is connected with nut (5) through coupler (3), nut (5) links with screw mandrel (4), one end of screw mandrel (4) is piston (7), and an end of strut bar (9) is that cushion cover (10) other end is piston (8).
2. automatic portable vehicle jack according to claim 1 is characterized in that: adopt the self-propelled vehicle battery power as propulsion source.
