Referring to fig. 1, when the error-proofing mechanism system of the rear-door sludge dump truck provided by the embodiment of the present invention is used specifically, the error-proofing mechanism system provided by the embodiment of the present invention is connected according to the schematic diagram in fig. 1, and each component is installed at the corresponding position of the rear-door sludge dump truck according to the above-mentioned structural arrangement, each normally open or normally closed switch should meet basic use requirements, for example, the front-top cylinder lift control normally open proximity switch 1 is used for detecting the rotation of the rear door, i.e. the opening degree of the rear door, therefore, the detection distance between the normally open proximity switch and the component in the rear door at least meets its practical requirements, for example, the detection distance between the front-top cylinder lift control normally open proximity switch 1 is 1 to 10cm, therefore, the distance between the component embedded in the rear door when closed and associated with the proximity switch should be 1 to 10cm, the distance between the components built into the back door associated with the proximity switch should be greater than 10cm when the back door is open. Similarly, other proximity switch setting principles in this application embodiment are the same as the principle of the normally open proximity switch 1 of the front top cylinder lifting control, and this application embodiment is not described in detail.
After the components are arranged and installed according to the requirements, when the rear door locking oil cylinder 12 is not located at the locking position, the rear door locking detection normally closed proximity switch 2 cannot detect the locking mechanism, the locking mechanism is powered on in a closed state, and the fault indicator lamp 4 connected with the rear door locking detection normally closed proximity switch is powered on to light up, so that a driver is reminded that the rear door is not locked, and misoperation of the driver is avoided.
When the oil cylinder of the back door locking oil cylinder 12 extends out, the back door is blocked when being closed, so that the back door can not fall and be closed when the oil cylinder of the back door locking oil cylinder 12 extends out.
When the rear door opening and closing oil cylinder 11 extends to open the rear door, the rear door closing detection normally-open proximity switch 3 cannot detect the disconnection of the locking mechanism, and the rear door locking three-gear automatic reset switch 5 cannot obtain the electrification of the electromagnetic valve of the multi-loop valve 13 so as to ensure that the rear door locking oil cylinder 12 extends to be locked.
For the rear door closing detection normally open proximity switch 3, when the rear door is opened, the rear door closing detection normally open proximity switch 3 cannot detect a rear door component and is in an off position, the rear door locking three-gear automatic reset switch 5 cannot be electrified to control the electromagnetic valve on the multi-loop valve 13 to close the rear door, and the rear door cannot fall and close.
When the rear door is not completely opened, the normally open proximity switch 1 for controlling the lifting of the front jacking oil cylinder cannot detect the disconnection of the rear door opening mechanism, the two-position three-way electromagnetic valve 9 is not electrified, the port P of the electromagnetic valve is closed, the hydraulic distribution valve does not control air to change the hydraulic oil in the front jacking oil cylinder, and the lifting oil cylinder 10 for the front jacking tank body cannot lift, so that the problems that a large number of goods exist in the tank, the rear door is impacted and deformed and is separated and the whole vehicle turns on one side due to the lifting of the front jacking oil cylinder in misoperation cannot occur.
The back door opening and closing three-gear automatic reset switch 6 is used for controlling the on-off of a power supply, the oil circuit of the opening and closing oil cylinder 11 is changed by controlling the on-off of the power supply of the electromagnetic valve on the multi-loop valve 13, and the oil cylinder is tested to lift or descend and is opened or closed correspondingly to the back door.
As an implementation mode, the mistake proofing mechanism system further comprises a chassis auxiliary air source 8, the chassis auxiliary air source is arranged on a chassis of the rear-opening sludge tank truck and is connected with the tank body lifting oil cylinder 10 through the two-position three-way electromagnetic valve member 9, and the chassis auxiliary air source 8 is used as an auxiliary air source when necessary.
