Abstract

The invention relates to an oil pump device for an automobile crane. The oil pump device comprises an oil pump, wherein the power input end of the oil pump is connected with a transmission shaft via a first adapting plate, and the other end of the transmission shaft is connected with a power take-off device via a second adapting plate; the oil pump is arranged on an oil pump support; the oil pump support is arranged on an automobile frame via an auxiliary support, and the oil pump support is an L-shaped bend board; a shaft hole is formed in one sideboard of the oil pump support; the power output end of the oil pump penetrates through the shaft hole and then is connected with the first adapting plate, and another sideboard of the oil pump support is used for being fixedly connected with the auxiliary support; both the two sideboards of the oil pump support are vertical to the ground; the auxiliary support comprises a box-type structure fixedly arranged on the automobile frame; a connecting board is fixedly connected with the sideboards of the oil pump support. The oil pump device for the automobile crane is shortened in the cantilever length of the oil pump support, improves the working stability of the oil pump device under the alternate load action, and eliminates a potential safety hazard of unbalancing of the transmission shaft.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an oil pump device for a truck crane. Background technique [0002] The oil pump device refers to a device that takes power from the power take-off of the engine or gearbox through the oil pump, and then transmits hydraulic power to the steering hydraulic power assist system and independent hydraulic cooling system of the truck crane through the oil pump. There are three common ways for the oil pump to take power from the power take-off: transmission shaft connection, coupling sleeve connection, and direct connection of the power take-off. [0003] The quality of the oil pump device is related to the quality of the truck crane. Once the setting of the oil pump device is unreasonable, the following failure phenomena will occur: oil leakage from the pump shaft head, breakage of the pump shaft head, disengagement of the transmission shaft itself, transmission shaft and pump spli...
