A reverse-proof net, a long front wheel and a hand-operated brake lever structure. The utility model not only can prolong the service life of the fork lift to be conveniently used on various goods yard goods yards and factory occasions, but also can protect the production safety of the operator.

Description

Light-weight hand hydraulic fork-lift

A kind of portable manual hydraulic pressure fork truck relates to the improvement of hand fork lifter.

Hand fork lifter is easy to operate with it, the machine manufacture factory large, medium and small in China still has certain use amount, but because old fashioned hand fork lifter is not equipped with hydraulic initiating means mostly, and the dress hydraulic initiating means arranged, because brake part and steering hardware easily flexibly do not use still sense inconvenience.Particularly, the fork truck that is loaded with weight is reeled in that mechanical department, building site, warehouse are many because of workpiece, ground is unequal.Because old fashioned fork truck do not have the collision prevention tilting prevention device, gently then rapid wear workpiece or goods, heavy then overturning goods from behind, the operator is also vulnerable.

The purpose of this utility model; be to provide a kind of portable manual hydraulic pressure fork truck; make starting power with hydraulic efficiency gear; and adopt light collision prevention bridge to take turns and the brake handle; make hand operated transport can carry big workpiece, big goods easily; can cross little obstacle easily again, prevent that goods from unloading the generation with casualty accident, can also protect operator's production safety.

The utility model is to implement like this, this portable manual hydraulic pressure fork truck is made up of vehicle frame, vehicle frame front-wheel, handgrip, trailing wheel, hydrostatic drive chain pole, shelf elevation angle change bar etc., wherein, above shelf, safety net is housed, an elevation angle is housed between the lower rail place of safety net and handgrip changes the gong bar, two front-wheels of vehicle frame, each adopts a cover eternal lasting wheel, and wherein, the diameter of trailing wheel and front-wheel ratio is generally 10:3.In addition, a hand-operated brake bar is housed on the wheel shaft of a trailing wheel.

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

Fig. 1 is a scheme drawing of the present utility model;

Fig. 2 is the constructional drawing that the elevation angle described in the utility model changes bar;

Fig. 3 is an eternal lasting rolling hitch composition described in the utility model;

Fig. 4 is a hand-operated brake bar structural representation described in the utility model;

Fig. 5 is that the A of hand-operated brake bar is to scheme drawing.

As shown in the figure, hand operated transport described in the utility model is made up of fork truck vehicle frame 1, vehicle frame front-wheel 2, fork truck handgrip 3, fork truck shelf 4, hydraulic efficiency starting pressure handle 5, driving chain pole 6, elevation angle change bar 7 and fork truck trailing wheel 8.Wherein, the anti-down net 9 of metal is housed in the back of fork truck shelf 4, to prevent that transporting in the process when accident takes place goods at fork truck topples over backward and injure the operator.As shown in Figure 2, it is 3 centers that are fixed on the fork truck handgrip that the elevation angle changes bar 7, be welded on again on the driving chain pole 6 of fork truck shelf 4, by shaking the position that screw rod 10 changes shelf 4 and handgrip 3, thereby change the hypsokinesis angle of shelf 4, its car load does not change ground-surface center of gravity behind the maintenance fork truck loading weight goods.Respectively being equipped with one group on two vehicle frame front-wheel 2 positions of hand operated transport prevents that road is uneven or has the eternal lasting of obstacle to take turns 11, its structure as shown in Figure 3, two blocks of A-frame plates 12 respectively are housed on front frame, the middle slip with vehicle frame by pin rod 13 connects together, at two angle ends in addition by two blocks of A-frame plates 12, back steamboat 14 and preceding steamboat 15 that a wheel footpath equates respectively are housed, form eternal lasting wheel 11, when fork truck is advanced forward when running into obstacle, because the effect of operator's thrust is pressed fork truck a little backward, eternal lasting wheel 11 is because the effect of pin rod, back steamboat 14 lands, and preceding steamboat 15 lifts and clears the jumps, when the operator continues to promote forward, because preceding steamboat 15 has landed, back steamboat 14 is soared, and clear an obstacle continues horizontal sliding forward together.Can not occur because the collide with state of single-wheel when running into obstacle prevented steadily transporting of cargo.In addition, hand operated transport described in the utility model on the wheel shaft of a trailing wheel 8 of its fork truck, is equipped with a hand-operated brake bar 16, as shown in Figure 4.This hand-operated brake bar 16 is by brake lever 17, the turning cylinder 18 of band head bearing 20, lower bearing 21 and connecting rod 19 are formed, simultaneously, bottom at fork truck handgrip 3 colludes 22 near being welded with a location of rising to fovea superior on the handle stem of brake lever 16, in case the operator with fork-truck steering after, the wheel synform of two trailing wheels becomes the tee T position, at this moment as long as oppositely being stuck in the location, colludes on 22 brake lever 17, since this moment two trailing wheels wheel to or quadrature can't advance forward or backward simultaneously, this hand operated transport just can be parked on the preposition steadily.Because the said hand operated transport of the utility model has adopted the brake lever lugs, and, the wheel footpath of trailing wheel 8 is 10:3 with the impeller diameter ratio of preceding eternal lasting wheel 11, when needs turn around fork truck to turn among a small circle, only need promote fork truck handgrip 3 then fork truck with braking checking, then fork truck can be a radius with fork truck underframe 21, with eternal lasting wheel 11 is that the garden heart is done light original place rotation, has broken the convention that can not make hand fork lifter turn round and turn in narrow and small place.

Adopt the hand operated transport of the said this structure of the utility model, both protected production safety, can prolong the service life of fork truck wheel again, more can make things convenient for and use leggiero in various occasions, be the light instrument of using of a kind of goods yard, factory more.
