Abstract
The invention discloses a micro jack which belongs to the field of jack machinery. The technical scheme is that the micro jack consists of an end cover, pins, a screw cover, top blocks, a base, a slider, a bolt, a jackscrew, a steel ring and the like, wherein the jackscrew is arranged in a screw hole of the base; one end of the jackscrew is clamped in a slider groove while the other end is welded with the steel ring; the slider is arranged in a horizontal groove of the base; the top blocks are arranged in a plurality of vertical grooves of the base; the smooth bottom surfaces of the top blocks make contact with the smooth inclined surfaces of the slider; the end cover and the screw cover are fixed on the base through the pins; the inclination angles of the inclined surfaces of the slider are the same and not greater than 45DEG; and the bolt is screwed with the slider through a through hole on the base. The micro jack has the beneficial effects of: achieving the aim of lifting objects by changing the rotation of the jackscrew into the vertical motion of the top blocks via using inclined surface principle, exponentially increasing the speed of changing parts in narrow spaces, and having reasonable design, novel structure, small volume, light weight, less investment, free lifting, simple operation, safety and high efficiency.
Description
Technical field
The present invention relates to a kind of suiting especially, belong to the elevator machinery field at the miniature Jack of narrow space operation.
Background technology
No matter existing Jack is mechanical type or fluid pressure type, all exist volume big, can't be in the problem of small space operation.Yet often require to carry out hoisting operation in the work at narrow space.Such as electric " burning silicon " accident takes place in the hot continuous rolling production line normal productive process, require fast the silicon control that damages in the Electric Appliance Cabinet to be changed, so that in time resume production.Yet silicon control must and interfere electric elements to disassemble with front and back panel in the replacing regulator cubicle, utilizes crowbar that the upper strata is lifted by operating personal again, and then carries out silicon control and change.Complex operation not only, and waste time and energy, have a strong impact on production and normally carry out, cause bigger waste, press for a kind of miniature Jack that is particularly suitable for carrying out hoisting operation of exploitation at narrow space.
Summary of the invention
The object of the invention is exactly the drawback that overcomes existing Jack, invents a kind of miniature Jack that is particularly suitable for carrying out at narrow space hoisting operation.
Technical scheme of the present invention is: miniature Jack is made up of end cap, pin, gland, jacking block, base, slide block, screw, jackscrew, steel ring etc.Jackscrew is installed in the screw of base; One end is connected in the slide block slot; The other end and steel ring weld together, slide block are installed in the horizontal slot of base, and jacking block is installed in some vertical channel of base; The smooth bottom surface of jacking block contacts with the smooth bevel of slide block, and end cap, gland pass through dowel fixes on base; The angle of bevel on each inclined-plane of slide block is identical, and is not more than 45 °; Screw revolves through through hole on the base and slide block and is in the same place.
The invention has the beneficial effects as follows: adopt inclined plane principle; Rotatablely moving of jackscrew changed into the vertical up and down movement of jacking block; Thereby reach the purpose of the object that hoists; Can significantly improve the speed of changing parts at narrow space, reasonable in design, novel structure, volume are little, in light weight, small investment, up-down freely, simple to operate, safe and efficient.
Description of drawings
Fig. 1 is a structure front elevational schematic of the present invention.
Fig. 2 is the schematic top plan view of Fig. 1.
The specific embodiment
Specify details of the present invention and service condition in conjunction with Fig. 1, Fig. 2.Miniature Jack is made up of end cap 1, pin 2, gland 3, jacking block 4, base 5, slide block 6, screw 7, jackscrew 8, steel ring 9 etc.; Jackscrew 8 is installed in the screw of base 5; One end is connected in slide block 6 grooves, the other end and steel ring 9 weld togethers, and slide block 6 is installed in the horizontal slot of base 5; Jacking block 4 is installed in some vertical channel of base 5; The smooth bottom surface of jacking block 4 contacts with the smooth bevel of slide block 6, makes the sliding-frictional resistance between the contact surface as far as possible little, and the height of contact surface is determined by the height of the object that hoists.End cap 1, gland 32 are fixed on the base 5 through pinning.When hoisting object, miniature Jack is placed under the object, clockwise rotates steel ring 9, steel ring 9 drives jackscrew 8 rotations, promotes slide block 6 in the time of jackscrew 8 rotations and is moved to the left, and slide block 6 moves drive jacking block 4 and rises, and accomplishes the action that hoists; During the decline object, rotate counterclockwise steel ring 9, steel ring 9 drives jackscrew 8 contrarotations, drives slide block 6 in the time of jackscrew 8 rotations and moves right, and jacking block 4 moves down under the effect of the gravity of object, accomplishes down maneuver.The angle of bevel on slide block 6 each inclined-plane is identical, and is not more than 45 °, can self-locking to guarantee to hoist stroke and descending stroke.Screw 7 revolves through through hole on the base 5 and slide block 6 and is in the same place, and its effect is: just in case can seize screw 7 when breaking down slide block 6 is moved right, jacking block 4 descends with object, is unlikely to stuck.The invention has the beneficial effects as follows: adopt inclined plane principle; Rotatablely moving of jackscrew 8 changed into the vertical up and down movement of jacking block 4; Thereby reach the purpose of the object that hoists; Can significantly improve the speed of changing parts at narrow space, reasonable in design, novel structure, volume are little, in light weight, small investment, up-down freely, simple to operate, safe and efficient.
