Description
Technical field
The utility model relates to the technical field of material conveyance equipment, is specifically a kind of fork wheel mechanism of tray truck.
Background technology
Tray truck is a kind of small-sized haulage equipment, and it has straddle like two pallet forks, can insert in the free entry of pallet, the front end of straddle has the road wheel of two minor diameters, being used for the weight of support tray goods can lift goods again, makes pallet or container built on stilts, then moves.Because first tray truck needs to pass in and out swimmingly pallet, therefore, the pallet fork of transport trolley, dropping to when minimum, need to have an accurate and suitable height.Tray truck both domestic and external, pallet fork drops to when minimum, and its minimum altitude is all no more than 90mm, and this is also the requirement of standard GB/T/T27542-2011 defined, and this regulation makes the fork wheel diameter maximum of tray truck can not surpass 90mm.At present, the common load-carrying capacity of tray truck both domestic and external is 2～2.5 tons, the material of wheel is pitched by external a few manufacturer by research and development, improve the various effort such as resistance to abrasion, protecting against shock, toughness and compressive strength of fork wheel material, develop load-carrying capacity and reached the tray truck of 3.5～4 tons, but the manufacturing cost of fork wheel is very expensive, and be difficult to over 6 months the service life of fork wheel.Therefore there is following shortcoming in the fork wheel mechanism of the tray truck of prior art:
1) load-carrying capacity of fork wheel is poor, even if improve the load-carrying capacity of fork wheel by the change of material, but brings expensive manufacturing cost; Meanwhile, the service life of fork wheel is shorter;
2), when vehicle passes through hollow, hollow produces to impact to fork wheel and causes jolting, shake and damaging of vehicle; Even, when fork wheel is absorbed in hollow, causes the unpassable phenomenon of vehicle, thereby greatly affect production efficiency.
Utility model content
Technical problem to be solved in the utility model is, provides that a kind of load-carrying capacity is strong, long service life, and the fork wheel mechanism of the tray truck that stationarity is good, crossing ability is high.
For solving the problems of the technologies described above, the fork wheel mechanism of the tray truck that the utility model provides, comprise that the fork being connected on pallet fork by fork wheel support plate takes turns, the quantity of described fork wheel be three and three fork wheel diameters identical, this fork wheel mechanism also comprises two connecting plates, described three fork wheels are arranged side by side and three fork wheels are all automatically connected between two connecting plates by axle and bearing rotary, and the upper end of fork wheel support plate is connected with pallet fork, lower end be connected that middle to pitch the connecting plate of taking turns hinged.
Described axle is divided into minor axis and major axis, and two, the both sides fork wheel of three fork wheels is all automatically connected between two connecting plates by minor axis and bearing rotary, and middle fork wheel is automatically connected between two connecting plates by major axis and bearing rotary; It is hinged with the lower end of fork wheel support plate that major axis stretches out two parts outside connecting plate.
The hinge place of the connecing Zhuo of described major axis and two connecting plates is provided with axle sleeve, and described axle sleeve is provided with to the flanging turning up at the outer face place of connecting plate.
Described fork wheel support plate and the hinged place of major axis have the oilhole that is used for filling lubricating oil radially.
Adopt after above structure, the utility model compared with prior art, has advantages of following:
1), because each pallet fork is all equipped with three fork wheels, three fork parallel installations of wheel and big or small identical, that is to say the contour installation of three fork wheels, therefore, when vehicle travels on smooth road surface, three fork wheels can be simultaneously stressed, makes vehicle have larger load-carrying capacity;
2) when vehicle passes through hollow, three fork wheels can keep two forks to take turns the while on road surface all the time, therefore, have avoided hollow produce impact and cause jolting, shake and damaging of vehicle fork wheel, protected other parts on vehicle, greatly improved service life;
3) when the structure of taking turns due to three forks makes vehicle be absorbed in hollow, can pass through smoothly, greatly improve the crossing ability of vehicle;
4) in the hinged place of fork wheel support plate and major axis, be provided with after the oilhole of lubricating oil, can inject lubricating oil, more guaranteed the alerting ability of fork wheel, also reduced friction, increase the service life.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
From the structural representation of the fork wheel mechanism of the utility model tray truck shown in Fig. 1 and Fig. 2, it comprises by fork wheel support plate 1 and is connected to the fork wheel 4 on pallet fork 2, the quantity of described fork wheel 4 be three and three fork wheel 4 diameters identical.This fork wheel mechanism also comprises two connecting plates 3, three described fork wheels 4 are arranged side by side and three fork wheels 4 are all automatically connected between two connecting plates 3 by axle and bearing rotary, the upper end of fork wheel support plate 1 is connected with pallet fork 2, and lower end is hinged with the connecting plate 3 that is connected middle fork wheel 4.
Two, the both sides fork wheel 4 that described axle is divided into minor axis 6 and 7, three fork wheels 4 of major axis is all automatically connected between two connecting plates 3 by minor axis 6 and bearing rotary, and middle fork wheel 4 is automatically connected between two connecting plates 3 by major axis 7 and bearing rotary; It is hinged with the lower end of fork wheel support plate 1 that major axis 7 stretches out two parts outside connecting plate 3.
The hinge place of the connecing Zhuo of described major axis 7 and two connecting plates 3 is provided with axle sleeve 5, and described axle sleeve 5 is provided with to the flanging turning up at the outer face place of connecting plate 3.
Described fork wheel support plate 1 has the oilhole 8 that is used for filling lubricating oil radially with the hinged place of major axis 7.
Shown in Fig. 3, when vehicle runs into hollow, top fork wheel is crossed hollow, after two fork wheels be positioned on level land simultaneously; And while contact with level land after top fork wheel is crossed hollow, middle fork wheel is suspended on hollow top, now two, the both sides fork in three fork wheels is taken turns and is positioned on the level land, front and back of hollow simultaneously; Continue to move ahead, foremost is all positioned on level land with two middle fork wheels, and backmost a fork is taken turns the top that is positioned at hollow; Until three fork wheels are all crossed hollow, in whole process, remain that two fork wheels contact with ground, therefore, move very steady.
Shown in Fig. 4, when vehicle runs into little slope, the process when running into hollow is identical, and in three fork wheels, being also has two fork wheels to contact with ground all the time, therefore, moves also very steady.
Shown in Fig. 5 and Fig. 6, when in prior art, single fork wheel runs into step, after the stressed decomposition in edge of fork wheel, some masterpiece is used for pitching wheel support plate, therefore, can cause the damage of other parts of vehicle.And adopt after trident wheel mechanism, after the stressed decomposition in edge of top fork wheel, fork wheel support plate is not subject to involving of impulsive force, therefore, has greatly improved service life.
