Abstract
The utility model relates to a control device of a windscreen wiper of an excavator. The control device comprises a windscreen wiper controller and a travel switch SQ arranged on the right upper portion of a cab of the excavator. One end of a relay J1 coil is connected with one end of a normally closed contact of the travel switch SQ, the other end of the normally closed contact of the travel switch SQ is connected with the ground, and the other end of the relay J1 coil is connected with a power supply through a windscreen wiper continuous switch. One end of a normally open contact of a relay J1 is connected with the windscreen wiper controller, and the other end of the normally open contact of the relay J1 is connected with one end of the normally closed contact of the travel switch SQ. One end of a relay J2 coil is connected with one end of the normally closed contact of the travel switch SQ, the other end of the normally closed contact of the travel switch SQ is connected with the ground, and the other end of the relay J2 coil is connected with the power supply through a windscreen pause switch. One end of a normally open contact of a relay J2 is connected with the windscreen wiper controller, and the other end of the normally open contact of the relay J2 is connected with one end of the normally closed contact of the travel switch SQ. The control device is high in safety due to the travel switch and convenient to use due to the fact that users do not need to do prevention work in advance.
Description
Technical field
The utility model relates to a kind of excavating machine, specifically, relates to a kind of excavating machine wiper control setup, belongs to technical field of electricity.
Background technology
At present; For making the excavating machine operating personal have more wide visual field, the excavating machine front window is designed to openable usually, when the front window pull-up; Front screen can move on the ceiling of operator's compartment along the track that is arranged in the operator's compartment, observes the place ahead or top to make things convenient for excavating machine operating personal when operation.When the excavating machine operating personal was outwards observed the front window pull-up in when work, be easy to run into front screen wiper switch, because traditional excavating machine is not provided with the anti-misoperation function for the wiper motor; Cause the wiper machine operation easily; Cause the windscreen wiper swing, poor stability is for fear of the generation of this problem; Need carry out defence work in advance, use inconvenient.
The utility model content
The problem that the utility model will solve is to above deficiency, and a kind of safe, easy to use excavating machine wiper control setup is provided.
For overcoming the above problems, the technical scheme that the utility model adopts is following: excavating machine wiper control setup is characterized in that: comprising:
Wiper controller, wiper controller is connected with rain shaving electrical machine D, is used to control rain shaving electrical machine D and does intermittently or continuously to turn round;
Travel switch SQ is arranged on excavating machine operator's compartment upper right side, touches travel switch SQ during the pull-up of excavating machine front window, travel switch SQ action, and when the excavating machine front window put down, travel switch SQ resetted;
Relay J 1, an end of a termination travel switch SQ normally closed contact of relay J 1 coil, the other end ground connection of travel switch SQ normally closed contact, the other end of relay J 1 coil is through continuous K switch 1 power connection of windscreen wiper;
One termination wiper controller of relay J 1 open contact, an end of another termination travel switch SQ normally closed contact of relay J 1 open contact.
Further improvement as technique scheme:
Control setup also comprises:
Relay J 2, an end of a termination travel switch SQ normally closed contact of relay J 2 coils, the other end ground connection of travel switch SQ normally closed contact, the other end of relay J 2 coils is through windscreen wiper pause switch K2 power connection;
One termination wiper controller of relay J 2 open contacts, an end of another termination travel switch SQ normally closed contact of relay J 2 open contacts.
The utility model adopts above technical scheme; Compared with prior art, have the following advantages: owing to be provided with travel switch, an end of relay J 1 and relay J 2 coils is through the normally closed contact ground connection of travel switch SQ; When the pull-up of excavating machine front window, touch travel switch SQ; Travel switch SQ action, the normally closed contact of travel switch SQ breaks off, and has cut off the power supply of relay J 1 and relay J 2 coils; Continuous K switch 1 of windscreen wiper this moment and windscreen wiper pause switch K2 can not control the work of rain shaving electrical machine D, and be safe; Do not need to carry out defence work in advance, easy to use.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Description of drawings
Accompanying drawing is the schematic circuit diagram of wiper control setup among the utility model embodiment.
The specific embodiment
As shown in the figure, excavating machine wiper control setup is characterized in that: comprising:
Wiper controller, wiper controller is connected with rain shaving electrical machine D, is used to control rain shaving electrical machine D and does intermittently or continuously to turn round;
Travel switch SQ is arranged on excavating machine operator's compartment upper right side, touches travel switch SQ during the pull-up of excavating machine front window, travel switch SQ action, and when the excavating machine front window put down, travel switch SQ resetted;
Relay J 1, an end of a termination travel switch SQ normally closed contact of relay J 1 coil, the other end ground connection of travel switch SQ normally closed contact, the other end of relay J 1 coil is through continuous K switch 1 power connection of windscreen wiper;
One termination wiper controller of relay J 1 open contact, an end of another termination travel switch SQ normally closed contact of relay J 1 open contact;
Relay J 2, an end of a termination travel switch SQ normally closed contact of relay J 2 coils, the other end ground connection of travel switch SQ normally closed contact, the other end of relay J 2 coils is through windscreen wiper pause switch K2 power connection;
One termination wiper controller of relay J 2 open contacts, an end of another termination travel switch SQ normally closed contact of relay J 2 open contacts.
When the pull-up of excavating machine front window, front window touches travel switch SQ, the push rod action of travel switch SQ; The normally closed contact of travel switch SQ breaks off; Cut off the power supply of relay J 1 and relay J 2 coils, continuous K switch 1 of closed windscreen wiper this moment and windscreen wiper pause switch K2, the coil and the power supply of relay J 1 and relay J 2 can not form C/LOOP; The open contact of relay J 1 and relay J 2 breaks off, and continuous K switch 1 of windscreen wiper and windscreen wiper pause switch K2 can not control the work of rain shaving electrical machine D; When the excavating machine front window put down, the push rod of travel switch SQ resetted, and the normally closed contact of travel switch SQ is closed, and continuous K switch 1 of windscreen wiper and windscreen wiper pause switch K2 could control the work of rain shaving electrical machine D.
