Abstract
The utility model discloses a hydraulic fuel tank cap of a forklift, which comprises a cover plate (10), and a fuel filling pipe (20), a fuel sucking pipe (30), a fuel returning pipe (40) and a suction pipe (50) which penetrate on the cover plate (10). The hydraulic fuel tank cap is characterized in that the cover plate is as thick as 6mm-8mm, and the positions of the fuel filling pipe (20), the fuel sucking pipe (30), the fuel returning pipe (40) and the suction pipe (50), which are contacted with the cover plate (10), are sealed and fixed by welding. Compared with the existing forklift hydraulic fuel tank cap, the hydraulic fuel tank cap has the advantage that the sealing performance is good.
Description
Technical field
The utility model relates to the fork truck technical field, especially relates to a kind of fork truck hydraulic oil case lid.
Background technique
Present fork truck all is the power that provides goods to move through a cover hydraulic system, and when the goods tonnage was big, the hydraulic system of fork truck needed higher output and reliability.The hydraulic system of fork truck produces pressure output through the hydraulic oil circulation; Hydraulic oil reservoir exists in the hydraulic oil container of fork truck; Therefore hydraulic oil container can bear bigger hydraulic fluid pressure, so the sealing requirements of hydraulic oil container is very high, and hydraulic oil has the dew of oozing a little; The capital causes forklift pressure output undesired, influences the proper functioning of fork truck.Because at present a tank cover all can be arranged at the hydraulic oil container top of fork truck, is penetrated with many pipelines on the cover plate, cover plate is fixed on the fuel tank through screw, and the general design of cover plate is all extremely thin, and easy deformation when receiving external force can have influence on the sealing of fuel tank; In addition, generally be to improve sealing between pipeline and the cover plate through adding seal ring, this sealing means is easy to generate the hydraulic oil infiltration, and sealing is also bad.
The model utility content
To the deficiency that above-mentioned existing technology exists, the purpose of the utility model provides a kind of fork truck hydraulic oil case lid, and it has good seal performance, advantage that can oil impregnate.
To achieve these goals; The technological scheme that the utility model adopted is: fork truck hydraulic oil case lid; Fork truck hydraulic oil case lid comprises cover plate, also comprises oil filling pipe, fuel sucking pipe, return tube and respirating tube on the cover plate; Said cover sheet thickness is 6～8 millimeters, and said oil filling pipe, fuel sucking pipe, return tube and respirating tube are fixed through welded seal with the contacted position of cover plate respectively.
Preferably, said oil filling pipe, fuel sucking pipe, return tube and respirating tube respectively with the perpendicularity of cover plate end face less than 0.15 millimeter.
Preferably, said respirating tube tip portion is through the resuscitation apparatus that has been threaded.
Preferably, the bottom of said fuel sucking pipe and return tube is connected with filter respectively.
After adopting said structure, the utility model is compared the advantage that is had with existing technology and is: not yielding because cover sheet thickness increases to some extent, so can not have influence on the sealing of hydraulic oil container.In addition; Through the welding manner sealing and fixing, make and connect into an overall structure between them between pipeline and the cover plate, can not become flexible; Therefore its sealing is very firm; The hydraulic oil phenomenon of osmosis can not take place, improved contact with the hydraulic oil case lid sealing of position of pipeline, fully for the fork truck proper functioning provides guarantee.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation at another visual angle of the utility model.
Among the figure: 10, cover plate; 20, oil filling pipe;
30, fuel sucking pipe; 40, return tube;
50, respirating tube; 51, resuscitation apparatus;
60, filter for molten.
Embodiment
The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model.
Embodiment, see that Fig. 1 is to shown in Figure 2:
The utility model is a kind of fork truck hydraulic oil case lid; Fork truck hydraulic oil case lid; Comprise cover plate 10, also comprise oil filling pipe 20, fuel sucking pipe 30, return tube 40 and respirating tube 50 on the cover plate 10, it is characterized in that; Said cover sheet thickness is 6～8 millimeters, and said oil filling pipe 20, fuel sucking pipe 30, return tube 40 and respirating tube 50 are fixed through welded seal with cover plate 10 contacted positions respectively.Because cover plate 10 thickness increase to some extent, and are not yielding, therefore can not have influence on the sealing of hydraulic oil container.In addition; Through the welding manner sealing and fixing, make and connect into an overall structure between them between pipeline and the cover plate 10, can not become flexible; Therefore its sealing is very firm; The hydraulic oil phenomenon of osmosis can not take place, improved contact with the hydraulic oil case lid sealing of position of pipeline, fully for the fork truck proper functioning provides guarantee.
In order to make between pipeline and the cover plate 10 welding easier, said oil filling pipe 20, fuel sucking pipe 30, return tube 40 and respirating tube 50 respectively with the perpendicularity of cover plate 10 end faces less than 0.15 millimeter, make that like this solder joint is more even, sealability is better.In order to reduce the influence of ambient pressure to hydraulic oil container inside; Respirating tube 50 tops are with linking to each other inside and outside the hydraulic oil container; But in order to prevent that impurity such as dust, rainwater from getting into hydraulic oil container;, neither influence respirating tube 50 and connect inside and outside the hydraulic oil container through the resuscitation apparatus 51 that has been threaded in said respirating tube 50 tip portion, can also avoid getting into foreign material.In order to make hydraulic oil turnover hydraulic oil container can both keep impurity few, said fuel sucking pipe 30 is connected with filter 60 respectively with the bottom of return tube 40.
The utility model has the advantage of good seal performance with respect to existing fork truck hydraulic oil case lid.
