Abstract

The invention discloses a continuous material feeding system and a control method and an elevating platform fire truck thereof. The control method includes the following steps: A. enabling a piston of a first pump material device to move towards a first limit position of the first pump material device; B. enabling a piston of a second pump material device to move towards the first limit position of the second pump material device before the piston of the first pump material device reaches the first limit position; C. enabling the piston of the first pump material device to move from the first limit position to the second limit position of the first pump material device before the piston of the second pump material device reaches the first limit position of the second pump material device; D. enabling the piston of the second pump material device to move from the first limit position to the second limit position of the second pump material device before the piston of the first pump material device reaches the second limit position of the first pump material device; and E. returning to the step A before the piston of the second pump material device reaches the second limit position of the second pump material device. By means of the system, the method and the truck, driving devices of the two pump material devices can change direction in staggering mode (namely the actions of the two driving devices have certain coincidence area), and flow fluctuation of material outlets is avoided.

Description

technical field [0001] The invention relates to the technical field of construction machinery pumping, in particular to a continuous feeding system and a control method thereof, and a fire truck for a climbing platform. Background technique [0002] The pumping system of fire trucks on climbing platforms in the prior art adopts the pumping system of double-acting cylinders. Specifically, the pumping system includes a water tank, a first pumping device, a second pumping device and a water outlet, wherein: the first A pumping device and the second pumping device both include a pumping cylinder and a driving device; the inside of the pumping cylinder is provided with a piston, and the piston forms a first water pumping interval between the internal intervals of the pumping cylinder. cavity and the second pumping cavity, the suction ports of the first pumping cavity and the second pumping cavity are connected to the water tank, the drains of the first pumping cavity and the seco...
