Example Embodiment

[0036] The present invention will be described in detail below in conjunction with specific embodiments and drawings.

[0037] The method for controlling the safe opening of the integral mobile hood of a foam fire truck of this embodiment includes the following steps:

[0038] The first step is to design the structure of the integral mobile engine cover: the integral mobile engine cover, such as Figure 1 to Figure 3 As shown, it includes an engine hood body 1, a guide rail installed on the engine hood body 1, a frame rail 4 fixedly connected to the engine hood body 1 and used to fix the engine 3, a bracket 5 arranged on the frame rail 4, A position sensor 6 on the bracket 5, a rotatable handle 7 arranged on the hood body 1, a locking pin 8 for connecting the handle 7 and the bracket 5, and a control unit arranged on the foam fire truck;

[0039] In the second step, when the engine 3 needs to be overhauled, rotate the handle 7 outward, and the locking pin 8 is separated from the bracke

Abstract

The invention relates to the technical field of engine covers, in particular to a control method for safe opening of an integrated movement type engine cover of a foam fire truck. When an engine needsto be overhauled, a handle is rotated outwards, a locking pin is separated from a support, a position sensor sends a disengagement signal to a control unit, the control unit cuts off an engine startsignal, and then the engine cannot be started; then, an engine cover body is dragged out in the direction far away from a vehicle frame longitudinal beam, and then the engine can be overhauled. When the engine cover needs to be closed, the handle is rotated outwards, the engine cover body is pushed towards the vehicle frame longitudinal beam, the handle is released when the engine cover body reaches a limiting point, the locking pin and the support are connected and locked, the position sensor sends a detected connection and locking signal of the locking pin and the support to the control unit, and the control unit then recovers the normal start function of the engine. By the adoption of the control method for safe opening of the integrated movement type engine cover of the foam fire truck, when the truck is repaired and maintained, the situation that relevant uninformed personnel conduct misoperation on the truck is avoided, and potential safety hazards are avoided.
