The carrier of speed.
Background technology
Hand hydraulic carrier is a kind of compact volume and convenience, and using flexible, loading capacity is big, durable goods porter
Tool, it is commonly called as " ox ".Carrier is in addition to the function with goods consigned, in order to facilitate landing goods, between chassis and wheel
With hydraulic means, in that context it may be convenient to car is pushed under container base, then raised domain with hydraulic pressure, holds up goods, just
Goods movement can be dragged, after arriving at, chassis is landed with hydraulic pressure, goods also lands therewith, in that context it may be convenient to which extraction is removed
Transport car.Eliminate the complex process of manpower transport.During existing hand hydraulic carrier use, no matter the weight of goods is
It is small greatly, the lifting speed of the pallet fork of hand hydraulic carrier is all constant, when goods is overweight, if lifting speed mistake
It hurry up, easily cause lifting process unstable, now need slower lifting speed to keep the stabilization of goods, when goods is lighter,
If it is excessively slow to lift speed, handling efficiency can be caused low.
The content of the invention
The utility model is for hand hydraulic carrier of the prior art lifting constant airspeed, it is impossible to according to goods weight
Adjust automatically lifts the drawbacks of speed, there is provided a kind of carrier that lifting speed can be automatically adjusted according to goods weight, this is manual
Hydraulic carrier can be automatically regulated to be slower lifting speed when goods is heavier, ensure the stability of lifting process, in goods
Faster lifting speed can be automatically regulated to be when lighter, ensure that the handling efficiency of carrier.
Goal of the invention of the present utility model is achieved through the following technical solutions：One kind can be adjusted automatically according to goods weight
The carrier of section lifting speed, including handle, hand fork lifter hydraulic cylinder, pedestal and by loading arm, the pallet fork back of the body, pallet fork forms

There is back-moving spring, the compression piston lower end is arranged with retainer ring, and retainer ring is fixedly connected with compression piston, retainer ring lateral surface
It is bonded with the side wall of input grease chamber, the compression piston lower surface is provided with two vertical cores, and compression piston is provided with to be connected with vertical core
Logical cross-drilled hole, the outlet of cross-drilled hole are located above retainer ring, and a check valve, two check valve controlling streams are respectively provided with two vertical cores
Body it is in opposite direction, lifting piston is provided with the output end grease chamber, lifting piston upper end be located at immediately below loading arm, lifts work
Hold beyond the Great Wall and loading arm is played a supportive role；When handle rotates around handle, at its lower end and hand fork lifter hydraulic cylinder hinged place, handle
Spring cup can be pressed downward, and spring cup can drive compression piston now compression piston can be by liquid to input oil interior compression
Force feed presses to output end grease chamber by oil piping system, so as to lift the hydraulic pressure of output end grease chamber, makes the lifting in output end grease chamber
Piston jacks up loading arm, lifts goods so as to allow pallet fork to rise, oil piping system can use the general manual fork of in the market
Oil channel structures in car hydraulic cylinder, in this course, when compression piston moves down, the hydraulic oil in input grease chamber, which reaches, to be set
Constant-pressure hydraulic oil can is entered above retainer ring below compression piston by one of check valve, when on compression piston
During shifting, hydraulic oil can be flowed to below compression piston above retainer ring by another check valve, now the reality of compression piston
The area of border acting surface is equal to the area of the cross section of compression piston in itself.When the hydraulic fluid pressure in input grease chamber does not reach
During established standardses, hydraulic oil can not be by check valve, and now the practical function face size of compression piston is equal on compression piston and set
There is the area of the cross section of fixed ring position, the area that compression piston is provided with the cross section of fixed ring position is more than compression piston
The area of the cross section of itself, so when the pressure of hydraulic oil reaches established standardses, the lifting speed of carrier upper fork compared with
Slowly, when the pressure of hydraulic oil is not reaching to established standardses, the lifting speed of carrier upper fork, and the pressure of hydraulic oil takes
Certainly in the weight of goods on carrier, so when goods weight reaches setting weight when pallet fork lifts, the act of carrier upper fork
Lifting speed is slower, and lifting is more steady, when when pallet fork lifts, goods weight is less than setting weight, the lifting speed of carrier upper fork
Comparatively fast, it is more efficient.
Preferably, the check valve, which includes a spring body and one, can block the stifled ball of vertical core port, spring body and stifled ball
It is fixedly connected, the setting direction of spring body and stifled ball in two check valves is on the contrary, enable one of check valve to make retainer ring
Under hydraulic oil entered by the check valve above retainer ring, another check valve can make the hydraulic oil above retainer ring pass through this
Check valve enters below retainer ring.
Preferably, the vertical core and cross-drilled hole are orthogonal.
Preferably, it is socketed with sealing ring on the compression piston.
Preferably, the sealing ring is located at below retainer ring.
Preferably, the compression piston is provided with the spacer pin for extending transversely through compression piston, spacer pin is located at the bullet
The top of spring lid, the spring cup are enclosed on compression piston.When spring cup is produced elastic force by back-moving spring upwards, spacer pin energy
It is spacing to the direction of motion progress of spring cup up, compression piston is produced upwards so as to which the elastic force of back-moving spring is converted into
Active force.
Compared with prior art, the utility model has the advantages that：Hand hydraulic carrier of the present utility model
When carrying heavier goods, the hydraulic oil in input grease chamber can pass through the area of check valve, the now acting surface of compression piston
Smaller, the The hydraulic oil of compression piston single extrusion is less, so lifting speed of the vehicle frame to goods is slower, can keep preferable
Stability, when carrying lighter goods, the hydraulic oil in input grease chamber can not pass through the work of check valve, now compression piston
With the cross section that face is retainer ring, area is larger, and the The hydraulic oil of compression piston single extrusion is more, so vehicle frame is to goods
Lifting speed, can guarantee that higher operating efficiency.The hand hydraulic carrier is also mounted with the pallet fork bottom of vehicle frame
It is horizontal walk wheel carrier, it is horizontal walk turnover bracket, it is horizontal walk cross frame, and be provided with preceding road wheel and row wheel, pass through a liter act support, rotate
Bar, link assembly can be adjusted to the position of preceding road wheel and row wheel, so as to so that before hand hydraulic carrier progress
After move or left and right transverse shifting, be easy to carry out transverse shifting in the less straight angle position in space, be easy in handling process
Direction adjustment.And the hand hydraulic carrier is provided with brake disc, the arc brake piece on brake disc is to trailing wheel medial surface
