Abstract
The utility model relates to a movable electric hoisting jack which is mainly composed of worm wheels, worm screws, screw rods, outer sleeves, elevating sleeves, manual adjusted screw rods, support pieces, wheels, etc. The utility model has the advantages of reasonable design, small size, convenient operation, labor saving and low cost. The movable electric hoisting jack can be moved and is suitable for being used as a supporting tool during the repair and maintenance of trucks of which the carrying tonnage is equal to and less than 12 tonnages.
Description
The utility model relates to a kind of mobile type electric jack that autotruck below 12 tons and 12 tons is safeguarded guarantee.
Adopt manual jack as lifting tool when at present, autotruck is safeguarded guarantee mostly.Manually jack generally can be divided into hydrostatic drive and two kinds of versions of mechanical drive, and mechanical drive can be straight gear transmission and bevel gear transmission again.Hydraulicdriven jack is laborsaving, but because to adopt rubber cup be sealing member, oozes more yieldingly because of oil after the general time, causes leakage phenomenon.Mechanically operated jack effort is used inconvenient.The jack volume of straight gear transmission is bigger, and cost is higher; Bevel geared jack is that fixed type is installed, and can not move arbitrarily.
At the defective or the deficiency of above-mentioned similar jack, the purpose of this utility model provide a kind of reasonable in design, easy to operate, flexibly laborsaving, volume is little, cost is low, the electronic jack that can move arbitrarily.
The utility model by worm gear case (1), cover plate (2), worm gear (3), worm screw (4), screw mandrel (5), outer tube (6), jacking sleeve (7), on lift stop nut (8), decline stop nut (9), hand adjustment screw mandrel (10), anchor plate (11), two road wheels (12), live axle (13), arm-rest frame (14), two-direction switch (15), 8 check screws (16), motor (17), belt (18), belt pulley (19) and form.8 check screws (16) are connected as a single entity worm gear case (1) and cover plate (2), and worm gear (3) and worm screw (4) are installed in the worm gear case (1).Screw mandrel (5) is vertically fixed on the axle center of worm gear (3).Outer tube (6) passes jacking sleeve (7) and screw mandrel (5) is vertically fixed on the cover plate (2).Jacking sleeve (7) is installed between outer tube (6) and the screw mandrel (5) and with screw mandrel (5) and is threaded, and the upper and lower end parts of jacking sleeve (7) is equipped with decline stop nut (9) and rising stop nut (8) respectively.Hand adjustment screw mandrel (10) is installed between jacking sleeve (7) and the screw mandrel (5) and with jacking sleeve (7) and is threaded, and anchor plate (11) is fixed on the top of hand adjustment screw mandrel (10).The live axle (3) that is installed on the worm gear case (1) links to each other two road wheels (12).The arm-rest frame (14) of two iron pipe compositions is fixed on the cover plate (2), and two-direction switch (15) is fixed on the arm-rest frame (14).Motor (17) is fixed on the cover plate (2) of road wheel (12) side, and belt pulley (19) is fixed on the end of worm screw (4), and belt (18) links to each other motor (17) with Pulley (19).
When mobile, with the subordinate arm-rest frame (14) of pressing, road wheel (12) lands, and worm gear case (1) is inclined upwardly.When moving to desired location, unclamp arm-rest frame (14), worm gear case (1) lands, and road wheel (12) is unsettled.Stir two-direction switch (15), motor (17) forward or reverse, by belt (18), Pulley (19), the screw mandrel (5) that drives worm screw (4) and worm gear (3) and be fixed on the worm gear (3) is done to rotate accordingly, and the rotation of screw mandrel (5) drives the perpendicular movement that jacking sleeve (7), hand adjustment screw mandrel (10) and anchor plate (11) are done rising together or descended.Two-direction switch (15) is resetted, and lifting position immobilizes.Last act stop nut (8) and decline stop nut (9) are used for limiting the ultimate range of electronic rising of the present utility model or decline.With hand rotating support piece (11), the hand adjustment screw mandrel (10) that is connected as a single entity rises or descends along jacking sleeve (7), is used for remedying the deficiency of electronic climb sometimes.The range of the utility model hand adjustment screw mandrel (10) is 200 millimeters, and the range of jacking sleeve (7) is 310 millimeters.
Principal feature of the present utility model is: 1. can move arbitrarily, easy to operate, applicability is good.2. electric labor-saving is safe and reliable, easy-maintaining.3. volume is little, and cost is low, and is profitable.
