Fig. 1 is a schematic diagram of the circuit of the present invention.
Detailed Description
As shown in figure 1, the comprehensive backup protection device for shaft sinking and vehicle stabilizing comprises a speed sensor for collecting vehicle stabilizing speed, the speed sensor is connected with a processor for transmitting collected data to the processor for processing, the processor is connected with a man-machine operation system, the speed sensor adopts an electromagnetic speed sensor and is installed at a large gear of a vehicle stabilizing winding drum, the comprehensive backup protection device further comprises a vehicle stabilizing electrical parameter protection device and a locking protection device, the vehicle stabilizing electrical parameter protection device adopts a motor comprehensive protector, the locking protection device adopts a monitoring sensor, and the monitoring sensor is installed on a safety brake and a work brake of a vehicle stabilizing.
In the embodiment, a special case for luxury instruments and meters is used as a main case of the comprehensive backup protection device, the material is an aluminum alloy forging and pressing structure, the thickness of a plate is two millimeters, the plate is subjected to spray molding, a German West novel Programmable Logic Controller (PLC) is selected as a main control element of an electrical part, the model is S7-200 SMART, and the corresponding input of an expansion signal is realized by adopting a series of modules, wherein the model is S7-2 DT.
The protection mainly realizes that an overspeed signal can be sent to a vehicle-stabilizing control system in time when the transmission of a vehicle-stabilizing fails, the vehicle-stabilizing control system is braked and stopped in time, the safety production is ensured, and the difficult problem that the vehicle-stabilizing brake fails when the vehicle-stabilizing transmission fails to reach fixed distance is fundamentally solved.
The field investigation shows that the speed of the sinking and stabilizing car can be obtained by a common counting method as long as the speed of the gear teeth of the large gear of the stabilizing car drum is which is less than half of the running period of the PLC due to the fact that the operating speed of the sinking and stabilizing car is low, the speed of the large gear of the stabilizing car drum can be obtained by a common counting method, the speed acquisition sensor adopts a magnetoelectric induction principle, is arranged at the large gear of the stabilizing car drum and transmits the speed pulse of the gear teeth in real time, and the model of the electromagnetic speed sensor is LJ18A 3.
The protection includes overvoltage, undervoltage, overcurrent, overload, deficiency, etc. the protection needs to be realized by loading a motor comprehensive protector with special functions in a vehicle stabilizing control circuit, a backup protection device collects signals transmitted by the motor protector to meet the protection function of the electrical parameters and achieves the protection purpose through PLC relay operation transmission, the front end data processing of every protection functions of the motor protector realizes that the motor protector is inconvenient to operate and process by PLC because the related output quantity has more input parameters of the motor protection parameters, and the processing by the motor protector is simple and convenient, moreover, the motor protector is mature and reliable in the current stage, no independent development of hardware is needed, and the motor comprehensive protector is adopted for the protection of the electrical parameters of the stable vehicle, and the model is FYCD-1 type product.
The locking protection of a safety brake and a working brake is characterized in that a safety brake and a working brake protection function are arranged in a vehicle stabilizing control system, when a vehicle is started, a main motor and the working brake can be started only after the safety brake acts in place, the locking relation is very important, an old vehicle stabilizing control circuit cannot ensure the reliability of the vehicle stabilizing control circuit, and PLC frequency conversion vehicle stabilizing control equipment at the present stage is relatively reliable, so that the locking protection function of the safety brake and the working brake of each vehicle stabilizing needs to be realized since the vehicle stabilizing backup protection is realized.
And (3) man-machine conversation, namely setting an observation interface and a parameter setting interface on a touch screen on the backup protection device, wherein an operator only needs to observe related parameters and states in the operation of the stable vehicle under normal conditions, before the device is put into operation, the tooth number of a large gear, the circumference of the large gear and an overspeed protection value of the stable vehicle need to be input into a main control PLC (programmable logic controller) through corresponding interfaces, and overvoltage, undervoltage, overload, overcurrent and phase loss values of a stable vehicle motor are set on a motor protector, wherein the man-machine interface selects a West son original touch screen with the model of SMART 700V IE 3.
And (3) after the series of protection functions are realized, loading signals into a vehicle stabilizing control circuit in a dry contact mode, sending out sound and light alarm signals by a backup protection device under the abnormal running state of the vehicle stabilizing, and simultaneously controlling the output lock of a control circuit to control the running of the vehicle stabilizing to form complete running protection systems.
