Description

Hydraulic tool car

The utility model relates to a kind of with artificial promotion, carrying part, working position apparatus and small article, carrying vehicle that can lifting.This car is a kind of be used for transporting between factory floor inside, workshop and the workshop part, instrument, anchor clamps, mould and other working position apparatuses or small article, and the carrying article can be elevated to certain position, light carrying vehicle.It also can be used to carry all kinds of small articles in shop, bookstore even family.

At present, between factory floor inside, workshop and workshop, transport part, working position apparatus and all do not have certain standard form carrying vehicle, use the hand barrow of three-wheel vehicle, homemade different size often, or remove shoulder with hand and lift, labour intensity is big, efficiency is low, can not guarantee personal safety, also causes having collided with, damage, influenced the safety in production in the factory and carrying out production strictly in line with rules and regulations of part or working position apparatus easily.

The purpose of this utility model provides a kind of artificial promotion, light, standard form carrying vehicle.The article that this car can the carrying constant weight (exceeding manually can promoting) make the pallet of placing article rise or descend in the mode of manual handling hydraulic efficiency pressure system.Pallet is risen to (or dropping to) and the position that the article place of laying maintains an equal level mutually, easily article are shifted onto on the pallet then, perhaps the article on the pallet are shifted onto and laid the place.

The utility model is achieved in that the hydraulic tool car by steel car body, hydraulic efficiency elevation structure, can form for the pallet and the annex thereof of carrying carrying article.The steel car body is formed by troughing plate welding, and an end is welded with the handlebar that is bent into steel pipe, and two front-wheels are directional wheels, and two trailing wheels are cardan wheels, is convenient to artificial promotion, turn radius is little, dexterity is convenient.There is a hydraulic efficiency elevation structure at the car body middle part, and the piston rod end of this mechanism directly is connected with the pallet component of bearing article; The piston rod end also can be fixed on the crossbeam that inserts the gate-type slip guide pillar in the body post, is fixing pallet above the gate-type slip guide pillar.Make plunger pump work with foot-operated mode, fluid is pumped in the oil cylinder, promote piston and piston rod and rise, pallet also rises to the position that needs thereupon.Mode with foot-operated or bar handle is opened valve, because action of gravity, the cylinder inner fluid flows back to fuel tank slowly, and piston and piston rod descend, and pallet also drops to the position that needs thereupon.The speed of pallet lifting and position can be controlled.Safety valve is housed in the hydraulic efficiency pressure system, and when load reached 1.25 times of rated loads, safety valve was opened automatically, guaranteed that pallet and hydraulic efficiency pressure system are not damaged.Guide rod or gate-type slip guide pillar are housed on the hydraulic tool car, guarantee that pallet and piston rod are stressed evenly, pallet moves up and down freely.

Another kind of structure is: plug-in mounting sliding support in gate-type slip guide pillar, the both sides of the crossbeam of slip guide pillar are respectively installed a pulley, are with chain on the pulley, and an end of chain is installed on the chassis of car body, and the other end is fixed on the bottom of sliding support.When piston rod rises, drive guide pillar and rise, the pulley on the guide pillar also increases, the drive chain moves, and chain drives the gate-type sliding support and raises, and above the gate-type sliding support pallet is housed, along with the rising of piston rod, pallet also increases like this, and the lift of pallet is 2 times of piston rod lift.Otherwise the distance when pallet descends also is 2 times of piston rod dropping distance.Rolling cart compact conformation like this, rapid operation.

Owing to adopted such scheme, the hydraulic tool car can be carried article easily, and the article of carrying can be raise or drop to the position that needs, and the direct then article with carrying push from pallet to be laid, or article are directly shifted onto on the pallet.Like this, the convenient in carrying of article, laborsaving, vehicle type structure is simple, compactness.
