Abstract
The utility model provides a standard type manhandled car which can be widely used for conveying and lifting small heavies. The car body is made of steel, two front wheels are directional wheels, and two rear wheels are steering wheels. A hydraulic lifting mechanism is situated at the back of the car, and the position that is slightly before the hydraulic lifting mechanism is provided with tubular guide rails. A cargo bearing bracket is matched with the guide rails, the hydraulic lifting mechanism is manually operated to lift the cargo bearing bracket and the heavies. The lifting speed of the hydraulic lifting mechanism can be controlled. With the utility model, the heavies can be lifted to the position that is identical to the place for unloading articles, and the heavies can be conveniently pushed out of cargo bearing bracket of the hydraulic lifting car.
Description
The utility model relates to a kind of with manpower promotion, carrying heavy goods, liftable carrying vehicle.This car is a kind of hydraulic lift truck that is widely used in factory, station, harbour, airport, warehouse, hospital and has all occasions of smooth place need carrying small-sized weight.Particularly this car has adopted the novel tubular guide rail, and the car deadweight is lightened, and its portability is significantly different with common traditional hydraulic lift truck.
At present, domestic and international common hydraulic lift truck as the fork truck of various power and manpower hydraulic lift truck etc., generally adopts and joins some rollers in the channel-section steel groove and make guide rail structure, is used for the lifting weight.Though this guide rail structure can bear bigger moment of flexure, but, exist the weakness of energy charge thing owing to the structure heaviness.Especially in small manual hydraulic lift truck field, the deadweight of the car of more this structure of people is troublesome.Below the 400kg hoisting capacity level other hydraulic lift truck aspect especially like this.
The purpose of this utility model provides a kind of from heavy and light, light, flexible, the high efficiency hydraulic lift truck of operation.
The purpose of this utility model is achieved in that the tubular guide rail hydraulic lift truck is made up of car body, oil pump, hydraulic ram, sprocket wheel, chain, guide rail, cargo carrying support and carrying support top shoe and bottom roller etc.The steel car body is formed by the channel-section steel welding.Oil pump, hydraulic ram, sprocket wheel, chain are selected the serial universal standard for use or are optional parts during design.Two guide rails are made by steel pipe, the guide rail lower end is connected with car body, the middle-end part equidistantly is fixed in the car body stand, the upper end is bent into semicircular arc, the straight line portion of whole guide rail is recessed to be set in the cargo carrying support top shoe, constitute bearing fit, and the straight line portion guide rail constitutes the cooperation of rolling again again by the clamping of cargo carrying support bottom roller.That is to say,, be actually the cooperation of sliding and rolling down when cargo carrying support during along the tubular guide rail lifting.Two location wheels are installed in the front lower place of car, and two steered wheels are installed in the back lower place, and the setting of wheel is the same with common hydraulic lift truck.During operation, make plunger pump work with foot-operated mode earlier, fluid is pumped in the oil cylinder, promote piston and piston rod, the gear type sprocket wheel of piston rod upper end also rises.Because the upright crossbeam of chain one end on the sprocket wheel and car body links to each other, the other end and cargo carrying support join, thereby cargo carrying support and weight are raised.When the oil cylinder off-load, by gravity cylinder inner fluid is pushed back fuel tank.With above-mentioned sequence of operation antithesis, weight also descends.The rising or falling speed of weight, highly equal may command.Safety valve is housed in the hydraulic efficiency pressure system,, thereby has guaranteed the safety of system when when overload, safety valve self-opening.
The utility model only is domestic widely used common hydraulic lift truck about half for people provide deadweight.Operate more flexiblely, lifting efficient is higher, and can save great deal of steel, saves the product of manpower.Its use has a extensive future, and not only can use in use occasions such as factory, station, harbour, airport, warehouse, hospitals, and a kind of brand-new version of novel tubular guide rail can be provided in the lifting equipment field.

With Fig. 1, Fig. 2 hydraulic circuit principle of work of the present utility model is described: when foot-operated treadle (9) makes plunger pump (1) work, fluid is pumped into oil cylinder (5), the gear type sprocket wheel (11) that promotes piston, piston rod (13) drive piston rod upper end rises, because chain (10) one ends on the sprocket wheel (11) link to each other with the upright crossbeam of car body, the other end and cargo carrying support (15) join, and cargo carrying support (15) is raised with goods.When oil cylinder (5) off-load, by gravity cylinder inner fluid is pushed back fuel tank (6) piston rod (13) sprocket wheel (11) chain (10) and cargo carrying support (15) together drops to the requirement position.When surpassing rated load, safety valve (3) is opened, thereby has guaranteed the safety of system.
Fig. 2 and embodiment shown in Figure 3 are by car body, hydraulic efficiency elevation structure, and tubular guide rail and other annex are formed, and hydraulic efficiency elevation structure is positioned at rear vehicle, by base portion, and plunger pump (1) oil pump foot-driven lever (9) off-load flow regulating valve compositions such as (4).Valve (2) oil cylinder (5) piston rod (13) fuel tanks (6) etc. zero, assembly are installed in the base portion.The channel-section steel welding is adopted on car body (8) chassis, and bolt fastening structure is partly taked in car body (8) stand, also can adopt welding.Car body (8) chassis and tubular guide rail (12) be connected to spiral shell button nut structure, also can adopt welding.Car body (8) stand is a rectangle, and its front is used for fixing tubular guide rail (12) back and is used for fixing chain (10), and whole framework is whole stress form.The upper end of tubular guide rail (12) is bent into semi-round cantilever beam structure, this version has following advantage: meet the variation that guide rail bears moment of flexure 1., both the guide rail straight line portion was subjected to moment of flexure big for following 2/3 section, and last 1/3 section be subjected to the little actual conditions of moment of flexure, due to mainly being changed by sprocket wheel (11) traction angle.2. manufacturing process is simple, and cost is low.3. can be used as the auxiliary top dead point of oil cylinder, is that straight guide begins crooked place, point of contact here.4. the handle that can be used as car.Guide rail can also be made arc or rectangle.Cargo carrying support (15) is by cargo carrying support top shoe (14), makes that guide rail is recessed to be set among the slide block (14), and leaves the unique one degree of freedom that slides along the tubular guide rail axis that has only of cargo carrying support for.Slide block (14) all with the wedge angle that tubular guide rail (12) rubs mutually, all make arc chord angle, thereby solved movement interference problem between the two.Cargo carrying support bottom roller is two, and the interior circular arc of roller (16) is consistent with guide rail (12) external arc, during cargo carrying support (15) lifting, two tubular guide rails (12) with a side arc groove clamping all the time.The purpose of this utility model reaches by above narration.
