Problems solved by technology
[0003] Since car driving and forklift driving share the steering system, braking system, clutch system and transmission system of the car cab, and the car cab and forklift cab are in two directions and cannot see each other, then in the actual operation process, there will be The car cab and the forklift cab operate the same part at the same time, causing disorder or unexpected operation of the operated parts. Even if the car cab and the forklift cab operate different parts at the same time, unexpected operations will occur, and the driving of the car or the operation of the forklift cannot be guaranteed. safety
For example, when the car is still on the spot and the forklift is working, if there are misoperations in the cab to operate the engine ignition switch, shift gears, start and walk, etc., resulting in sudden engine shutdown and car walking when the forklift needs to work on the spot, it will first affect The normal operation of the forklift will bring unexpected safety hazards to the forklift operation

Embodiment Construction
[0034] Such as figure 1 As shown, a car with a forklift operation function is equipped with forklift-related devices such as a mast 3 and a forklift cab 2 at the rear of the car, so that it has the main functions of a forklift, such as loading and unloading and moving functions, and various devices and systems are properly installed , so that it has both the car and the forklift can be used at the same time, and all the advantages of the forklift and the car can be changed flexibly.
[0035] For this reason, a car cab 1 is installed in front of the body of an ordinary car as a common vehicle, and a forklift cab 2 and a door frame 3 are installed at the rear of the car body.
[0036] In addition, in order to meet the engineering needs, the fork part can be replaced by other operating parts as required, or other operating parts can be installed on the mast to form a vehicle with multiple functions. For example, on the forklift frame of the forklift operating device, a lifting d...

The invention relates to a safe control device and method, in particular to a safe control device and method for a multifunctional work car. Switchover element control devices S (SQ and SC) are adopted by the safe control device for determining the control attribution of a cab engine ignition switch S1, a vice cab engine ignition switch S2, a master cab electronic accelerator pedal switch YM1 and a vice cab electronic accelerator pedal switch YM2 so that operation control power attribution intention can be determined before a driver enters a master cab or a vice cab, and thus driving and operation safety of the car with the forklift operation function is ensured. The problems that an operated part is disordered in performance or accidental operation occurs due to the fact that the same part is operated by an existing car cab and a forklift cab simultaneously, and accidents occur when the car cab and the forklift cab simultaneously operate different parts are solved, and the safe control device and method have positive meaning for ensuring car driving or forklift operation safety.
Description
technical field [0001] The present invention relates to a safety control device and method, in particular to a safety control device and method of a multifunctional work vehicle. Background technique [0002] Chinese invention patent CN102216196B discloses a car equipped with a forklift operation function. A mast with a forklift function is installed at the rear of the car body, and a forklift driver that can operate a forklift function is installed in front of the mast. It includes a steering system, a braking system, a clutch system and a transmission system that can be used for shared car driving. It can use the main functions of a forklift, such as loading, unloading and transferring, and has the rapidity and mobility of a car. [0003] Since car driving and forklift driving share the steering system, braking system, clutch system and transmission system of the car cab, and the car cab and forklift cab are in two directions and cannot see each other, then in the actual o...
