Description
Technical field
The invention belongs to haulage equipment technical field, and in particular to a kind of hand hydraulic carrier.
Background technology
Hand hydraulic carrier is a kind of compact volume and convenience, using flexible, and loading capacity is big, durable goods porter
Tool, is commonly called as " ox ".Carrier is in addition to the function with goods consigned, landing goods for convenience, between chassis and wheel
With hydraulic means, in that context it may be convenient to car is pushed under container base, then domain is raised with hydraulic pressure, hold 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 it is small, hand hydraulic carrier greatly that the weight of goods, which is,
The lifting speed of pallet fork be all constant, when goods is overweight, if lifting excessive velocities, are easily caused lifting process not
Surely, now need slower lifting speed to keep the stabilization of goods, when goods is lighter, if lifting speed is excessively slow, can lead
Cause handling efficiency low;Meanwhile, the steering of existing manual transport trolley can only be controlled by trailing wheel, when encounter straight corner and turn
When Angle Position space is smaller, manual transport trolley turns to inconvenient, or even is difficult to steering and can not pass through.Existing hand-hydraulic is carried
Car does not possess brake function substantially, and part has its braking quality of the manual transport trolley of brake function poor in time, and manual
During the use of carrier, it is sometimes necessary to which go up a slope descending, manual transport trolley or braking quality without brake function
The manual transport trolley of difference is very easily slipped by slope, and is likely to result in the generation of some dangerous phenomenons.
The content of the invention
The present invention lifts constant airspeed for hand hydraulic carrier of the prior art, it is impossible to automatic according to goods weight
Adjustment lifting speed, while turning to the drawbacks of inconvenient, braking quality is poor, there is provided a kind of hand hydraulic carrier, the manual liquid
Pressure carrier slower lifting speed can be automatically regulated to be when goods is heavier, it is ensured that the stability of lifting process, goods compared with
Faster lifting speed can be automatically regulated to be when light, it is ensured that the handling efficiency of carrier, while the hand hydraulic carrier exists
Pallet fork bottom is improved, and the hand hydraulic carrier is carried out transverse shifting, and with good braking quality, is prevented
Only hand hydraulic carrier is slipped by slope in use.
The goal of the invention of the present invention is achieved through the following technical solutions:A kind of hand hydraulic carrier, including handle,
Hand fork lifter hydraulic cylinder, pedestal and the vehicle frame being made up of loading arm, the pallet fork back of the body, pallet fork, handle, at its lower end and hand fork lifter hydraulic pressure
Cylinder is hinged, and pedestal is located at below loading arm, and pedestal and loading arm are parallel to each other, and the hand fork lifter hydraulic cylinder is arranged on pedestal
Between loading arm, pedestal is provided with the main shaft through pedestal, and main shaft upper end is fixedly connected with hand fork lifter hydraulic cylinder bottom, main
Axle lower end is fixedly connected with the hind axle of laterally setting, and hind axle two ends are each provided with one can be after hind axle rotation
Wheel;The pallet fork back is hinged with a liter act support, rises act support outer end and is hinged at pedestal.
The hind axle is provided with the brake disc being connected with connecting seat, connecting seat for hindering rear wheel, brake disc
The rotation connecting rod for being used for controlling brake disc working condition is provided with, the handle is provided with brake handle, and brake handle is with turning
Brake cable is provided between dynamic connecting rod;Brake handle can control brake disc to brake trailing wheel by brake cable, after preventing
Wheel is rotated.
The hand fork lifter hydraulic cylinder includes cylinder body, cylinder body and is provided with input grease chamber and output end grease chamber, input oil
Connected between room and output end grease chamber by oil piping system, liquid is filled with input grease chamber, output end grease chamber and oil piping system
Force feed;Compression piston is provided with the input grease chamber, compression piston upper end is connected with spring cup, set between spring cup and cylinder body
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

Logical cross-drilled hole, the outlet of cross-drilled hole is 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 is located at immediately below loading arm, and lifting is lived
Hold beyond the Great Wall and loading arm is played a supportive role;When handle is rotated 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 to the oily interior compression of input, now compression piston can be by liquid
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 jack-up loading arm, lifts goods, oil piping system can use the general manual fork of in the market so as to allow pallet fork to rise
Oil channel structures in car hydraulic cylinder, in this course, when compression piston is moved down, the hydraulic oil in input grease chamber, which reaches, to be set
Constant-pressure hydraulic oil can just be entered above retainer ring from compression piston lower section by one of check valve, when on compression piston
During shifting, hydraulic oil can be flowed to below compression piston from retainer ring top 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 during pallet fork lifting, the act of carrier upper fork
Lifting speed is slower, and lifting is more steady, when when pallet fork is lifted, goods weight is less than setting weight, the lifting speed of carrier upper fork
Comparatively fast, it is more efficient.
The pallet fork bottom along pallet fork front end be sequentially provided with it is horizontal walk wheel carrier, it is horizontal walk turnover bracket, it is horizontal walk cross frame, institute
State it is horizontal walk wheel carrier by a front axle with it is horizontal walk turnover bracket be hinged, front axle provided with can around front axle rotate move ahead
