Abstract

The utility model belongs to conveyers capable of lifting workpiece, being suitable for conveying and charging minitype workpiece with manpower in dwarf warehouses. The utility model is composed of clamping parts (11, 12, 13, 14), lifting parts (5, 7, 16), two oil hydraulic jacks (4, 6), moving trolleys (9, 10, 15), two spring releasing brakes (7), a pair of pedal rods (2), and a pair of mechanical arms (8). The mechanical arms connect forces made by the two jacks through hinges so as to clamp and lift workpiece. The utility model has the advantages of simple structure, low cost, rapid and convenient conveying and charging, safety, and small occupation of land.

Description

Foot-operated hydraulic clamp promotes loading-unloading vehicle

The utility model belongs to the lifting Handling device of object, is applicable to automobile fitting, and the small-sized object and the storehouse of equipment depot (ED) are short and small, the lifting difficulty, and the object that manpower can't be moved is made the usefulness of handling.

Storage room between some underground storehouses and independent one, the object that more heavier manpower can't be moved just can not be deposited or shoulder with a plurality of people and lift, and very waste time and energy.And for example, have enough to meet the need the too waste again of small-sized object with the driving weight-lifting equipment that lifts by crane tens tons in some large-scale diversification warehouses.

The purpose of this utility model is to be to provide a kind of reducing labor intensity, and increases work efficiency, and can improve the little space that can't have enough to meet the need at some, and the object that manpower can't be moved is made the loading-unloading vehicle of the usefulness of handling.

Its loading and unloading characteristics are that it is different with general crane handling method, crane is down to carry from eminence, and this loading-unloading vehicle is to lift from the bottom, and advantage is to deposit a top does not have the space, the crane bar is stretched the object that do not advance just can be very convenient with these loading and unloading, such as changing storage battery on the automobile etc.

This loading-unloading vehicle is by clamping part (11～14), lifting piece (5,7,16), and two oil jacks (4,6), a billy gate (9,10,15), two springs declutch (17), a secondary foot-driven lever (2), a pair of mechanical arm (8) is formed.It adopts simple mechanical lever principle to produce one tension earlier, makes manipulator transfer gripping power to by hinge, manipulator is risen with oil pump again, thereby is reached the purpose that object is raised, and object is delivered to the place that needs with billy gate again.

It is reasonable in design, simple in structure that this hydraulic clamp promotes loading-unloading vehicle, and cost is lower, handling is fast and convenient, safe in utilization and take up an area of for a short time, applying unit can save time with laborsaving with this loading-unloading vehicle, needn't be again with heavy manual labor carrying or raise some heavier objects.

Do further below in conjunction with drawings and Examples:

Accompanying drawing 1 is the front elevational schematic that foot-operated hydraulic clamp promotes loading-unloading vehicle, and Fig. 2 is that scheme drawing is looked on this device right side, and Fig. 3 is this device schematic top plan view.

Label 1-jack among the figure declutches, 2-starting jack foot-driven lever, 3-billy gate hinge, 4-clamping oil jack, 5-lifting jack hinge, 6-lifting oil jack, 7-lifting jack balance hinge, 8-mechanical arm, 9-bearing wheel, 10-wheel flutter, 11-clamp arm movable axis, 12-clamping jack hinge, 13-clamping jack kink, 14-clamping jack tressel, 15-billy gate support, 16-promoting the location hinge, 17-spring declutches.

Loading-unloading vehicle is pushed into to be needed by the carrying workpiece, lifting height by a clamping oil jack 4 overlaps 13 oblique tops with two struts of symmetry and produces horizontal thrust, the hinge 5 that promoted jack 6 tops before advancing produces the power of embracing with its manipulator to the center, thereby reach the effect of clamping article, another promotes oil jack 6 startings then, the hinge position is raised, because other end jail connects the fastening side rod 11 of transport trolley, so the manipulator of clamping article slowly improves, object is raised liftoff, and turn to dolly object to be delivered to other place that needs, trammer handle is other to have a pair of jack to declutch 1, earlier pine promotes and raises jack 6, the loose grasping firmly power jack 4 in back, and the power of oil pump jack is by two groups of foot-driven levers and foot-driven lever backspring are formed up and down.

Claims

1, a kind of foot-operated hydraulic clamp promotes loading-unloading vehicle, it is characterized in that, it is by clamping part (11～14), lifting piece (5,7,16), two oil jacks (4,6), a billy gate (9,10,15), two springs declutch (17), one secondary foot-driven lever (2), a pair of mechanical arm (8) is formed.

2, foot-operated hydraulic clamp according to claim 1 promotes loading-unloading vehicle, it is characterized in that, mechanical arm (8) is that the hinge by clamping part and lifting piece is connected.
