Description
Technical field
The utility model is related to a kind of fork truck, the fork truck door frame idler wheel structure of more particularly to a kind of improvement.
Background technology
Roller is supporting guiding movement part in portal frame system, is divided to longitudinally and laterally two groups, respectively symmetrically is arranged in interior
On outer mast and goods shelf.Longitudinal roller bears the active force in door frame plane, is using column flange plate as guide rail
Main carrying power transmission roller.And lateral roller bears the side force in door frame plane, active force using column web as guide rail
Small, diameter is also small.It is main in existing forklift door frame system to use composite rolling wheel as supporting guiding movement part, will be lateral
Roller is arranged on the center of longitudinal roller.Composite rolling wheel makes the clipping room of longitudinal roller and lateral roller away from overlapping, and reduces
Construction size simultaneously simplifies installation.But the portal frame system arranged using the roller based on composite rolling wheel, occurs in that gantry channel-steel abdomen
Door frame such as rocks at the phenomenon when plate serious wear, fork truck are fully loaded with raising.This phenomena reduces the performance of fork truck vehicle, stability and
Security performance.
The inner upright mounting roller commonly used as shown in Figure 1A, Figure 1B, inner upright mounting 1 ' passes through one group of composite rolling wheel 2 ' on inner upright mounting
One group of longitudinal roller and the guiding of one group of side wheel with outer mast, move along a straight line along above and below the progress of outer mast channel-section steel.It is interior
Longitudinal roller 21 ' in door frame composite rolling wheel 2 ' is acted on before and after outer mast channel-section steel on the inside of wing plate, the side in composite rolling wheel 2 '
Roller 22 ' is acted on on the inside of outer mast channel-section steel web.
The goods shelf roller commonly used as shown in Fig. 1 C, Fig. 1 D, goods shelf 1 " passes through two groups of composite rolling wheels 2 " on goods shelf
Guiding, along inner upright mounting channel-section steel carry out above and below move along a straight line.Longitudinal roller 21 " in the composite rolling wheel of goods shelf 1 " 2 " is acted on
Before and after inner upright mounting channel-section steel on wing plate inner side, the side wheel 22 " in composite rolling wheel is acted on on the inside of inner upright mounting channel-section steel web.
Thoroughly to efficiently solve this problem, technical staff has carried out fine disassembling observation simultaneously at the scene to portal frame system
Using scientific and reasonable analysis means, it is believed that the roller arrangement of portal frame system is the main cause for producing this phenomenon.It is interior during fully loaded raising
Outer mast roller spacing changes with raising, and roller pressure also changes therewith.Roller spacing is big when raising is relatively low, and stress is small, raising
Minimum to roller spacing during maximum height, at this moment roller pressure is maximum.Side wheel in composite rolling wheel is limited due to self structure,
Roller diameter and roller thickness are all smaller, cause gantry channel-steel web specific contact pressure larger, so as to produce wear phenomenon.Channel-section steel abdomen
The abrasion of plate causes the effect gap increase of side wheel, reduces portal frame system rigidity and stability, therefore door frame has been fully loaded with and risen to
When high-order, occasionally there is shaking phenomenon generation.
The content of the invention
The purpose of this utility model is the forklift door frame rolling for providing a kind of portal frame system rigidity and the good improvement of stability
Wheel construction.
To achieve the above object, technical solution of the present utility model is：
The utility model is a kind of fork truck door frame idler wheel structure of improvement, including outer mast, inner upright mounting, goods shelf；It is described
Inner upright mounting slipped by inner upright mounting roller thereon on the channel-section steel of outer mast, goods shelf is slided by goods shelf roller thereon
It is connected on the channel-section steel of inner upright mounting；Described inner upright mounting roller includes side wheel, described one built in one group of longitudinal roller and one group
The longitudinal roller of group respectively it is rotatable be socketed in the rotating shaft of the bottom both sides of inner upright mounting and the direction of rotation of longitudinal roller with it is interior
Door frame side wall is parallel, and side wheel built in one group is rotatable respectively to be nested with the bottom race of inner upright mounting and built-in side wheel
Direction of rotation is vertical with inner upright mounting side wall；Described goods shelf roller include more than one group longitudinal roller, side wheel built in one group,
One group of external side wheel；Rotating shaft, interior race, outer race are respectively equipped with two longerons of described goods shelf, more than one group is indulged
The direction of rotation that way roller is socketed in the rotating shaft of goods shelf longeron and longitudinal direction roller respectively is parallel with goods shelf stringer sides wall, interior
Put that side wheel is rotatable to be nested with interior race and the direction of rotation of built-in side wheel is vertical with goods shelf stringer sides wall, it is external
Side wheel is rotatable to be nested with outer race and the direction of rotation of external side wheel is vertical with goods shelf stringer sides wall.
Described goods shelf is successively set on goods shelf longeron provided with three groups of longitudinal rollers, three groups of longitudinal rollers.
, can be effective due to optimization of the utility model by pair roller arrangement and portal-framed structure after such scheme
Solve gantry channel-steel web serious wear, door frame and the phenomenon such as rock, improve vehicle transaction capabilities, stability and security performance.Tool
Structural reform is entered as follows：
Inner upright mounting roller is arranged：Cancel composite rolling wheel mode, wheel mode is sidewindered with built-in using longitudinal roller.It is built-in to sidewinder
The side wheel being more than on acts in composite rolling wheel is taken turns, the specific contact pressure of independent side wheel is less than composite rolling wheel, Neng Gouyou
The wear phenomenon of the reduction channel-section steel web of effect, improves side wheel service life and lifts the performance, stability and peace of fork truck vehicle
Full performance.
Goods shelf roller is arranged：Cancel longitudinal roller-composite rolling wheel mode, using longitudinal roller, built-in side wheel with it is outer
Put and sidewinder wheel mode.Built-in side wheel is acted in inner upright mounting channel-section steel on coxostermum, and external side wheel acts on inner upright mounting channel-section steel
On front wing panel end face.Built-in side wheel is all higher than the side wheel in composite rolling wheel with external side wheel on acts, independent
The specific contact pressure of side wheel is less than composite rolling wheel, can effectively reduce the wear phenomenon of channel-section steel web, improves side wheel and uses
Life-span and the performance, stability and security performance for lifting fork truck vehicle.
Outer mast roller is arranged：Continue to use longitudinal roller and sidewinder wheel mode with built-in, while built-in side wheel specification is from rule
The larger side wheel of lattice substitutes former built-in side wheel.New built-in side wheel is more than former built-in side wheel on acts, connects
Touch and be less than former built-in side wheel than pressure, the wear phenomenon of channel-section steel web can be effectively reduced, side wheel service life is improved simultaneously
Lift performance, stability and the security performance of fork truck vehicle.
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
