Abstract

The utility model relates to a forklift appliance supplying oil mechanism. The device is characterized in that the mechanism comprises a high-pressure hose and a hose pulley. A hose pulley is arranged on a middle gantry, the other pair of hose pulleys is arranged on an upper end of a hoisting cylinder which is arranged on an inner gantry. Two high-pressure hoses are bridged on the hose pulley through a four-way elbow and are connected with the forklift appliance. The utility model is simple in structure, due to the using principle of the hose pulley, the transformation relation of fixation and movement are realized skillfully. The device only uses the components such as the pulley, a feeding oil hose, a pipe joint and the other fixing plate seat, etc., with low cost of design, manufacture and maintenance. The device is compact in structure, which guarantees non mutual interference in the movement. The device is convenient and rapid installation and maintenance.

Description

Sebific duct pulley-type lift truck attachment oil supply mechanism

The utility model relates to a kind of lift truck attachment oil supply mechanism.

Fork truck is mixed as the special-purpose accessory of multiple fork truck such as sideshifter, paper roll folder, load push-pull and rotating clamp for realizing stacking, the transport operation under the different work environment, makes it have every functions such as sidesway, clamping, push-and-pull and rotation.Fork truck will be realized the action of this respect, often all be by it actuating unit---hydraulic ram is finished, inevitable just the hydraulic pressure of fork truck can need be delivered on the accessory by certain oil circuit.At home and abroad, fork truck hoisting system structure also is not quite similar, but is subjected to the restriction of itself function of fork truck, and fork truck hoists all need finish hoisting in the certain altitude scope, decline and stacking operation.External all is a kind of products that have special-purpose tube coiling appts of design, and it is made up of disc type track, tensioning spring, oily articulated joint and anchor fitting etc., does not have this series products at home.This tube coiling appts manufacture difficulty, productive costs are all very high, import price about 4000 yuan, add upper pipeline and relevant tube joint list group oil circuit total cost will reach about 5000 yuan.On the other hand, because this send oil pipe line all to be wrapped on the disc type track, the oil pressure loss is high, and concerning the lift truck attachment that the high oil pressure request is arranged, this fuel-feed system is also not satisfactory.Besides should the installation and maintenance of special use tube coiling appts also inconvenient, tensioning spring often uses, and easily loses efficacy, and causes user's use cost very high.

The utility model provides a kind of simple in structure, the sebific duct pulley-type lift truck attachment oil supply mechanism of low cost of manufacture by improvements over the prior art.

Concrete technical solution is such:

Sebific duct pulley-type lift truck attachment oil supply mechanism, comprise high-pressure rubber pipe and sebific duct pulley, it is characterized in that two are advanced, an end that goes out high-pressure rubber pipe is communicated with the four-way elbow respectively, the four-way elbow is located at a side on the outer mast of fork truck, in on the door frame homonymy be provided with a sebific duct pulley: a pair of coaxial sebific duct pulley is located on the piston rod of lift oil tank before the inner upright mounting inside, two advance, go out high-pressure rubber pipe and stride the sebific duct pulley of establishing on the middle door frame, through being located at the four-way elbow of inner upright mounting bottom, stride again and established two coaxial sebific duct pulleys, be connected on two pass joints on the goods shelf, last two advance, going out high-pressure rubber pipe is connected on the lift truck attachment.

The utility model is simple in structure, and it is by the use principle of movable and fixed pulley, has realized transformation relation fixing, motion dexterously, has only used pulley, send oil rubber hose, assemblies such as adaptor union and other adapter plate seat, and design, manufacturing and maintenance cost are all very low.It has realized hydraulic oil is delivered to accessory safely and effectively: during fork truck work, hoisting system is finished from the lower to the eminence and is hoisted, stacking, down during the degradation motion, this device can guarantee that fuel feeding is unimpeded, and loss of pressure is little: because this apparatus structure compactness, guarantee not interfere mutually in the motion, this device installation, maintenance is convenient and swift.

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

Embodiment 1:

Sebific duct pulley-type lift truck attachment oil supply mechanism comprises high-pressure rubber pipe and sebific duct pulley.Two ends into and out of high-pressure rubber pipe 1 are communicated with four-way elbow 2 respectively, and four-way elbow 2 is fixedly mounted on a side on the outer mast 7 of fork truck, and homonymy is installed with a sebific duct pulley 3 on the middle door frame 8.A pair of coaxial sebific duct pulley 5 is fixedly mounted on the piston rod upper end of inner upright mounting 9 inner preceding lift oil tanks, be communicated with four-way elbow 2 two into and out of high-pressure rubber pipe 1 stride established in sebific duct pulley 3 on the door frame 8, through being installed in two logical elbows 4 of inner upright mounting 9 bottoms, stride again and established two coaxial sebific duct pulleys 7, be connected on two pass joints 6 on the goods shelf 10, last two are connected on the lift truck attachment into and out of high-pressure rubber pipe.

This device forms and send, the oil return closed loop system.

In the use, fork truck is when hoisting goods,

sebific duct pulley

3,5, four-way elbow 4, two pass joints 6 etc. all can with middle door frame 8, inner upright mounting 9, goods shelf and accessory 10 hoist or fall and up or down the motion, high-pressure rubber pipe can carry out curvilinear movement by

sebific duct pulley

3,5 respectively, thereby realizes the accessory oil circuit supply under the state of kinematic motion.

Claims

1, sebific duct pulley-type lift truck attachment oil supply mechanism, comprise high-pressure rubber pipe and sebific duct pulley, it is characterized in that two ends into and out of high-pressure rubber pipe are communicated with the four-way elbow respectively, the four-way elbow is located at a side on the outer mast of fork truck, and homonymy is provided with a sebific duct pulley on the middle door frame; A pair of coaxial sebific duct pulley is located at the piston rod upper end of lift oil tank before the inner upright mounting inside, two into and out of high-pressure rubber pipe stride established in sebific duct pulley on the door frame, through being located at the four-way elbow of inner upright mounting bottom, stride again and established two coaxial sebific duct pulleys, be connected on two pass joints on the goods shelf, last two are connected on the lift truck attachment into and out of high-pressure rubber pipe.
