Abstract
The utility model discloses an electrical control system for a rock loading machine, which comprises a power supply, a raising bucket motor D1, a walking motor D2, a control circuit and a forward and reverse rotation control circuit. The raising bucket motor D1 and the walking motor D2 are connected with the power supply, the control circuit is connected with the raising bucket motor D1, and the forward and reverse rotation control circuit is connected with the walking motor D2. The electrical control system is characterized in that the electrical control system further comprises an automatic air switch ZK, and the total system is connected with an external power supply through the automatic air switch ZK. The electrical control system is simple in manufacture and low in cost, and is simply, conveniently and rapidly operated in practical operation, the automatic air switch ZK resolves the problem that power cannot be switched off as original main contactors are adhered with each other, can switch off power in time when necessary, guarantees equipment and personal safety, and has effect of automatic safety protection.
Description
Technical field
The utility model relates to a kind of dirt loader electrical control system.
Background technology
Dirt loader is a kind of mine charging appliance, and its purposes is with ore or the rock haulage device of packing into, dirt loader by walking mechanism, raise bucket mechanism, scraper bowl part, electrical control division and grade and form.Existing dirt loader electric control system by main contactor CX, raise bucket motor contactor C, the forward and reverse contactor CN of movable motor and CE and control button etc. are formed.The effect of main contactor CX is to be switched on or switched off power supply, because dirt loader is inching button control, start frequent, starting current is big, in use the contacts of contactor scaling loss is serious, particularly is easy to stick together behind the main contactor CX pitting of contacts and can't disconnects, and can not in time cut off the electricity supply, machine can not in time stop, and often causes equipment and personal injury.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of and can overcome above-mentioned defective, the dirt loader electrical control system that can in time cut off the electricity supply when needed machine is in time stopped.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of dirt loader electrical control system, comprise power supply, be connected with power supply raise bucket motor and walking motor and with the positive and reverse rotation control circuit of raising the bucket control circuit that is connected of motor and being connected with the motor of walking, it is characterized in that: also comprise automatic air-break switch ZK, whole system is connected with external power source by automatic air-break switch.
Raise the bucket motor and come control action by the bucket motor contactor C that raises on its control circuit, the walking motor is by forward and reverse contactor CN and CE control action on its control circuit, because the control button of dirt loader is electronic control button, start frequent, in case the contacts of contactor fault occurring sticks together and can not disconnect, when machine can't stop, can constitute harm to the equipment and the person.At this moment can cut off the electricity supply by direct control automatic air-break switch ZK, reach the safeguard protection effect, and the automatic air-break switch ZK deenergization of also can under improper situations such as overload, under-voltage, phase shortage, threading off voluntarily, automatic protection functions finished.
The beneficial effect that the utility model had is: make simple; cost is low; simple, convenient when practical operation, quick; automatic air-break switch ZK has overcome the problem that original main contactor adhesion can't deenergization; can in time cut off the power supply when needed; assurance equipment and personal safety, and have the effect of automatic safe protective.
Description of drawings
Fig. 1 is the utility model electrical schematic diagram.
Fig. 2 is former electric control circuit electrical schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1: a kind of dirt loader electrical control system, comprise power supply, be connected with power supply raise bucket motor D1 and walking motor D2 and with raise control circuit that bucket motor D1 is connected and the positive and reverse rotation control circuit that is connected with the motor D2 that walks, also comprise automatic air-break switch ZK, whole system is connected with external power source by automatic air-break switch ZK.
Raise the bucket motor and come control action by the bucket motor contactor C that raises on its control circuit, the walking motor is by forward and reverse contactor CN and CE control action on its control circuit, because the control button of dirt loader is the crawl control button, start frequent, in case the contacts of contactor fault occurring sticks together and can not disconnect, when machine can't stop, can constitute harm to the equipment and the person.At this moment can cut off the electricity supply by direct control automatic air-break switch ZK, reach the safeguard protection effect, and the automatic air-break switch ZK deenergization of also can under improper situations such as overload, under-voltage, phase shortage, threading off voluntarily, automatic protection functions finished.
Wherein with raise control circuit that bucket motor D1 is connected and the positive and reverse rotation control circuit that is connected with the motor D2 that walks, be present common circuit, various equivalent modifications all can realize.
Automatic air-break switch ZK has overcome the problem that original main contactor CX adhesion can't deenergization, can in time cut off the power supply when needed, and assurance equipment and personal safety, and have the effect of automatic safe protective.
