Embodiment Construction

[0034] It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict. Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0035] Combine below Figure 2 to Figure 3 , The preferred embodiment of the present invention will be further described in detail.

[0036] The fuel tank of this embodiment is used in a crane and includes a tank body 1 and an oil suction assembly and an oil return assembly provided on the tank body 1. In addition, the fuel tank also includes a partition 5 and an oil pipe assembly. The partition 5 is arranged in the box 1 to divide the box 1 into a first cavity 11 and a second cavity 12 along the length direction. The top of the partition 5 is also provided with a balance hole 10 for balancing the air pressure of each cavity. The oil pipe assembly includes at least one oil pipe 3, t...

Abstract

The invention discloses a crane and a fuel tank thereof. The fuel tank is applied to the crane and comprises a tank body, an oil suction assembly and an oil return assembly which are arranged on the tank body, a partition board and an oil pipe assembly. The partition board is arranged in the tank body and divides the tank body into two cavities in the length direction, and balancing holes used for balancing pressure of the two cavities are arranged at the top of the partition board. The oil pipe assembly comprises at least one oil pipe arranged in a first cavity and fixedly connected with the partition board. The fuel tank solves the problem of flaming out of an engine caused by incapability of fuel oil sucking due to little oil amount when the crane climbs up a hill, and is simple and reliable in structure and easy to popularize.

Description

Technical field [0001] The invention relates to the field of engineering machinery, in particular to a crane and a fuel tank thereof. Background technique [0002] At present, large-tonnage cranes have a large engine power. In order to ensure the driving range, the fuel tank volume should be as large as possible. However, due to vehicle layout, the fuel tank has a small cross section and a long length, and the fuel tank suction pipe is arranged in the middle of the fuel tank. This creates a problem. When the vehicle is going uphill, if the fuel tank is low, the fuel will be collected at the end of the tank, such as figure 1 As shown, this will cause the suction pipe to fail to absorb oil, and eventually cause the engine to stall, and the vehicle will stop on a half slope, which is very dangerous. [0003] In order to better ensure the operation of the engine, the fuel tank should ensure that the engine can absorb fuel when climbing a slope to ensure the normal operation of the engi...
