Description

Four-way crab row lift work car

The utility model relates to the Operation Van of four-way translation and vertical lift.

Present short-distance transportation and vertical lift Operation Van as being used for the access goods in the storehouse, comprise flat car body and the job platform jacking system that is fixed on the car body sailed, because its wheel can only be done forward and backward travel or sweeping curve travels, therefore being difficult in narrow space is transported to three-dimensional every nook and cranny with goods, and bigger operation path need be provided, cause the effective usable floor area of storehouse to reduce.

In view of above-mentioned, the purpose of this utility model provides a kind ofly can travel nimbly and freely, make a detour at small space, goods is delivered to the four-way crab row lift work car of three dimensional space every nook and cranny.

Technical solution of the present utility model has two.

Scheme one: four-way crab row lift work car comprises car body, the job platform jacking system, it is characterized in that before car body, being respectively equipped with the crossbeam mid point on the after cross member is fulcrum, with it with the continuous drive axle of pin hinge, device has drive wheel on each drive axle, flower wheel, two rods turn to oil cylinder and drive the driving speed reduction gearing of drive wheel rotation with electrical motor by transmission gear, drive wheel and flower wheel are arranged in four jiaos of car bodies with diagonal manner, drive wheel bracket and flower wheel support all link by bearing and drive axle, turn to two rods of oil cylinder to fix with drive wheel bracket and flower wheel support respectively, traction drive wheel and flower wheel turn to synchronously.

Scheme two: four-way crab row lift work car comprises car body, the job platform jacking system, it is characterized in that before car body, being respectively equipped with the crossbeam mid point on the after cross member is fulcrum, with it with the continuous drive axle of pin hinge, device has two drive wheels on each drive axle, two rods turn to oil cylinder and drive the driving speed reduction gearing of drive wheel rotation with electrical motor by transmission gear, drive wheel is arranged in four jiaos of car bodies, drive wheel bracket all links by bearing and drive axle, turn to two rods of oil cylinder to fix with two drive wheel bracket that are contained on the same drive axle respectively, draw two drive wheels and turn to synchronously.

The four wheels of four-way crab row lift work car of the present utility model is because before adopting, drive wheel and flower wheel that back diagonal angle is arranged, or four drive wheels, and there are two rods to turn to oil cylinder traction wheel to turn to synchronously, so can realize neatly advancing, retreat, move to left, the four-way that moves to right walking, can also left avertence change, right avertence is changeed, even can pivot stud, the coordinating operation platform lifting device can make vehicle arrive the operation of three-dimensional every nook and cranny in narrow space, again because four wheels is to be connected with the car body hinge by drive axle, so when meeting uneven road surface, can guarantee that all wheels of car body land simultaneously.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a kind of concrete structure scheme drawing of the utility model;

Fig. 2 is the A-A section-drawing of Fig. 1;

Fig. 3 is the instantiation that drives speed reduction gearing;

Fig. 4 is the bearing scheme drawing that connects drive axle and wheel support;

Fig. 6 is a door frame column lift work car outside drawing.

What Fig. 1 provided is the forward sight or the schematic rear view of the four-way crab row lift work car of the utility model scheme one.With reference to Fig. 1, Fig. 2, four-way crab row lift work car comprises car body 1, is located at the job platform jacking system 2 on the car body, (figure is a scissors fork elevating job platform full state), there are two drive axles 3 in every Operation Van, installs respectively on the forward and backward crossbeam of car body.In the diagram concrete structure, device has drive wheel 5, flower wheel 6, two rod to turn to oil cylinder 7 and driving speed reduction gearing 8 on each drive axle, drive wheel 5 and flower wheel 6 are arranged in four jiaos of car bodies with diagonal manner, drive wheel bracket 9 all links to each other with drive axle 3 by bearing 11 with flower wheel support 10, drive axle 3 utilizes the mid point hinge of bearing pin 4 and crossbeam 13 to link to each other, and can swing around bearing pin, like this, when meeting uneven ground, can guarantee that wheel all lands.Drive axle 3 is around the amplitude of fluctuation of bearing pin 4, and the available adjustment screw is controlled, and in this example, set screw 16 is installed on the vehicle frame, when Operation Van's rising operation, makes set screw prop up drive axle, can prevent that job platform from rocking.Turn to two piston rods 12,12 ' respectively of oil cylinder 7 fixing, turn to synchronously by its traction drive wheel and flower wheel with drive wheel bracket 9 and flower wheel support 10.

The four-way crab row lift work car of scheme two only is also to change the flower wheel in Fig. 1 structure 6 into drive wheel 5, and constitutes with driving speed reduction gearing 8 driven in rotation.

Usually, for making compact conformation, the driving speed reduction gearing in such scheme one, the scheme two can adopt structure as shown in Figure 3.The driving speed reduction gearing of illustrated example is to be nested with bearing 21 from inside to outside successively on the housing 20 of electrical motor, axially the lasso 23 and the drive wheel 5 of one section inner gear 22 to be arranged, the both ends of the surface that drive wheel bracket 9 surrounds drive wheel 5 upper semi-circles are fixed on the motor field frame, tighten intrinsic big gear wheel 25 and miniature gears 26 at a parallel driven shaft 24 with bearings with motor reel, wherein 27 engagements of the driving gear on big gear wheel 25 and the motor reel, miniature gears 26 meshes with the inner gear 22 of lasso 23.When electrical motor rotated, the driving gear 27 on the axle was by rotating simultaneously with its ingear big gear wheel 25 drive driven shafts 24 and miniature gears 26 like this, and miniature gears drives lasso 23 again and is enclosed within 5 rotations of the outer drive wheel of lasso.

The bearing 11 that is used to connect drive axle 3 and wheel support should be born axial force, bear diametral load again, though can adopt standard rolling bearing to combine, but so not only make structure complicated, also can increase setting height(from bottom), be simplified structure, reduce setting height(from bottom), here, bearing shown in Figure 4 is provided, and this bearing is by inner ring 31, outer ring 32 and plurality of rollers 33 constitutes, interior ring outer wall circumferentially and the outer ring inwall groove of triangular-section is circumferentially all arranged, in roller 33 places, the outer ring closes up in the circular groove of formation, the hole 34 that installation usefulness is axially arranged respectively in inner ring and outer ring, 35.The circular groove cross section that generally makes inside and outside circle close up formation is square for well, for ease of assembling, and the outer ring is divided into upper and lower two halves.During use, one of them and drive axle of inner ring and outer ring are fixed, another and wheel support are fixed.

Shown in Figure 5 is scissors fork elevating Operation Van.Shown in Figure 6 is door frame column lift work car, and their lifting bar available hydraulic oil cylinder 15 drives lifting.

Four-way crab row lift work car flexible operation of the present utility model, be applicable in narrow and carry out housekeeping to cargo storage, taking-up operation or the rising upkeep operation in high goods yard with to factory building, waiting room etc., adopt the utility model to help improving the storehouse usable floor area, can also raise labour productivity greatly, reduce labor intensity.
