Water tank structure of cleaning vehicle

Abstract

The invention discloses a water tank structure of a cleaning vehicle. The water tank structure comprises a bearing bottom frame for bearing and fixing and a tank body for containing cleaning water. The bearing bottom frame is arranged on the chassis in the length direction of the chassis of the cleaning vehicle and comprises longitudinal frameworks and transverse frameworks which are arranged in the length direction and the width direction of the chassis in a criss-cross mode, and the longitudinal frameworks and the transverse frameworks are connected to form an inwards-concave containing interval which is inwards concave from the top and used for containing the limiting tank body. And the tank body is welded and fixed in the inwards-concave containing section along the length direction of the bearing bottom frame, so that the tank body is stably supported on the chassis under the supporting and fixing effects of the bearing bottom frame and the containing and limiting effects of the inwards-concave containing section. According to the water tank structure of the cleaning vehicle, the tank body is evenly stressed, stress concentration is not prone to occurring at the welding joint, the risk of structural fatigue damage and the risk of water leakage of the tank body are reduced, the tank body can be stably fixed to the chassis, the stability of the water tank structure of the cleaning vehicle is enhanced, and the safety and reliability of structure operation are improved.

Description

technical field [0001] The invention relates to the technical field of sanitation cleaning vehicles, in particular to a water tank structure for a cleaning vehicle. Background technique [0002] The existing sanitation cleaning vehicle water tank welding device generally includes a tank body, a head, an underframe and a wave-proof plate, etc., wherein the underframe mainly includes longitudinal beams, beams, corbels, backing plates, and the like. The inertial force of the water tank of the sanitation cleaning vehicle is large when it is fully loaded. The bottom frame of the water tank supports the water tank and is installed on the chassis through the riding screw and the thrust plate to ensure the strength and stability of the structure of the cleaning vehicle water tank. The main load-bearing structure of the chassis is the left and right longitudinal beams, which are welded to the tank body through the longitudinal beam backing plate; the beams are connected to the left a...
