Abstract
The utility model discloses a small crane on vehicles which is suitable for carrying vehicles or other special type hoisting machines and comprises a base, an upright post, a hanging hook and a hanging arm. The upright post can rotate for 360 DEG through a swing mechanism; the swing mechanism comprises a rolling bearing and a worm gear pair which are positioned in a box body of the base. The hanging arm is composed of a basic arm, a telescopic arm and a manual arm; the arm length can be automatically regulated through a telescopic oil cylinder and the folding and the retraction of an amplitude variable oil cylinder, or the arm length can be regulated by electric or manual regulation. Having the advantages of energy saving, low cost, compact structure and neat external shape, the utility model can drive cylinders to revolve with minor input torque. The utility model can be suitable for loading and unloading operations in various different working occasions, being convenient and reliable.
Description
The utility model relates to a kind of vehicle with light loading and unloading loop wheel machine.
In little tonnage truck-mounted crane machine development and Design, require small-sized loop wheel machine compact conformation, oad is little, and is in light weight, will guarantee that promptly functions of use reaches requirement, and it is clean and tidy to meet good looking appearance again.At present, have the small-sized truck-mounted crane machine of multiple structural shape both at home and abroad, the swing type mechanism of these loop wheel machines adopts axial sleeve of bushing formula supporting usually, and when cylinder rotated, it is big that the cliding friction that revolution place produces causes turning round friction resistance moment, correspondingly horsepower input strengthens, expenditure of energy is many, and simultaneously, the swing type mechanism operated by rotary motion is above the casing of the base outside or column, make the volume of loop wheel machine big, contour structures and protective are relatively poor.The arm of loop wheel machine generally is two joints, generally adopts manual telescopic boom of physical construction or hydraulic telescopic arm and cable type machinery lifting structure, its radius of turn, and hoisting depths etc. are difficult to be suitable for the needs of various frequent little tonnage loading and unloading operations.
The purpose of this utility model provides a kind of compact conformation, saves the energy, the clean and tidy and easy to operate small-sized truck-mounted crane machine of outward appearance.
The purpose of this utility model is to realize like this.It comprises base, column, suspension hook and arm are characterized in: column is fixedly mounted on the base top, and can 360 ° of rotations by swing type mechanism, wherein, swing type mechanism is made up of the antifriction-bearing box that is installed in column cylinder bottom, worm gear and worm screw, and places in the base cabinet, amplitude oil cylinder and arm are set on the column, this arm is placed the telescopic boom in the basic arm and is contained in the interior manual arm of telescopic boom and formed by basic arm, and arm can be regained by amplitude oil cylinder is folding.The basic arm outside is fixed with telescopic oil cylinder, and arm can pass through telescopic oil cylinder (11) automatically regulating brachium.
Because swing type mechanism adopts antifriction-bearing box, worm gear and worm structure, and places in the base cabinet, dwindles its supporting spacing greatly, reduced friction resistance moment, drive barrel swivel with less input torque, but energy savings, cost-cutting, and make more compact structure, oad is less, and simultaneously, loop wheel machine is collapsible, profile is clean and tidy, and volume is less.Arm is three joint box type constructions, and two joint brachiums stretch and can realize by telescopic oil cylinder, also can change into manually, and are easy to use, reliable in the little tonnage loading and unloading operation of various different operating occasions.
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a swing type mechanism constructional drawing of the present utility model;
Fig. 3 is an arm stretched condition scheme drawing of the present utility model.
Referring to accompanying drawing, the utility model comprises base 1, column 6, suspension hook 12 and arm.By technique scheme, column 6 is fixedly mounted on base 1 top, swing type mechanism is made up of two short garden post coro bearngs 14, thrust ball bearing 18, worm gear 15 and worm screws 16 being installed in column 6 cylinder bottoms, and place in the casing of base 1, the inner ring of short garden post coro bearng 14 tightly is enclosed within the cylinder bottom of column 6, worm gear 15 is installed between two short garden post coro bearngs 14, and is simple and compact for structure.Operation multiple directional control valve 5, driving worm screw 16 by hydraulic gyration motor 4 rotates, worm screw 16 is meshed with worm gear 15, power is passed to worm gear 15, and the friction of revolution place changes friction of rolling into by original cliding friction, and the revolution friction drag significantly reduces, resisting moment when especially heavy duty is turned round obviously reduces, thereby drive column 6 barrel swivel with less input torque, can reduce energy consumption, cost-cutting.Thrust ball bearing 18 is installed near column 6 lower ends, rotates more flexibly, column 6 can 360 ° of rotations by swing type mechanism, make loop wheel machine place required orientation.Arm is a box type construction, it by basic arm 8, place the telescopic boom 9 in the basic arm 8 and manual arm 13 3 joints that are contained in the telescopic boom 9 are formed, have knock hole on the casing of basic arm 8, telescopic boom 9 and manual arm 13, and be provided with locating detent 19, be used to regulate brachium.Rotating fulcrum by bearing pin 20 formation, basic arm 8 and column 6 are flexibly connected, the piston body end of amplitude oil cylinder 7 is connected with basic arm 8 by bearing pin 21, amplitude oil cylinder 7 cylinder bodies are installed in the outside of column 6, make the two connection with bearing pin 22, arm can change in the lifting elevation coverage, to satisfy the needs of various sling heights and work range by amplitude oil cylinder 7 collapsible withdrawals.Basic arm 8 outsides are fixed with telescopic oil cylinder 11 vertically, and an end of the other end of basic arm 8 and telescopic boom 9 is fixed with connecting panel 23, and the cylinder body of telescopic oil cylinder 11 is captiveed joint with telescopic boom 9 with basic arm 8 respectively by connecting panel 23 with the piston body end.Suspension hook 12 is installed on the top of manual arm 13, telescopic oil cylinder 11 makes arm realize hydraulically extensible, and the automatically regulating brachium also changes within the specific limits, also can change the brachium of manual regulation telescopic boom 9 and manual arm 13 into, can manually shake worm screw, column 6 and lifting cargo are turned round together.The 2 pairs of big chambeies of amplitude oil cylinder 7 oil cylinders of hydraulically-controlled one-way valve that are installed in the fuel tank 3 lock as required, prevent to hang deposits yields and glide, and are safe and reliable during loading and unloading operation.The utility model is easy to operate, and is practical.
