Abstract
The utility model discloses a kind of pithead autoalarm, relate to field of PLC technology.This pithead autoalarm comprises PLC, control button, alarm lamp, sensor; The mouth of described PLC connects cage chair and the safety door on pithead limit; The switch that described control button controls the safety door of pithead closes; The lifting of described alarm lamp display pithead cage chair; Whether described sensor display safety door puts in place.The utility model achieves the normalization getting work and lander's control ready, can increase work efficiency and safety factor.
Description
Technical field
The utility model relates to field of PLC technology, particularly a kind of pithead autoalarm.
Background technology
Current handling material advances hooking work operation behaviour's handlebar equipment (material) or release cage, and then by signal dotting work, safety door, cage chair are closed, and completes whole operating process.Due to signal operation platform from east, west well head also has a segment distance, must establish that special messenger is responsible for observing east, the material of west well head, personnel come in and go out cage situation, then judged by bank man, sending except signal except oral to getting work ready, separately being operated by the signalman of operator's station again.Subsequently could closed safe door, rise cage chair, cage enters running state.This master mode, often due to mismate between the two, will cause such or such accident.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency do not interlocked to make up existing safety facilities program, provides a kind of control principle not changing former behaviour's vehicle device, makes full use of the point for subsequent use of the automatically controlled PLC of behaviour's car to realize the interlocking of well head safe facilities program.To achieve these goals, the technical scheme that the utility model is taked is: a kind of pithead autoalarm, comprises PLC, control button, alarm lamp, sensor; The mouth of described PLC connects cage chair and the safety door on pithead limit; The switch that described control button controls the safety door of pithead closes; The lifting of described alarm lamp display pithead cage chair; Whether described sensor display safety door puts in place.
Preferably, described PLC is MCS51 micro controller system.
Preferably, described control button is connected with the safety door single line of pithead.
Preferably, described sensor is well head safe door sensor.
The beneficial effects of the utility model are: the signal sent by getting room button ready interlocks with the safety door and cage chair program grasping car.Adopt the singlechip technology of technology maturation simultaneously, decrease cost and drop into.Control button is connected the switching that can realize automatic and manual operation and control with the safety door single line of pithead, decreases equipment investment, saves labour cost, effectively reduces service expenditure, improve work efficiency after changing.
Accompanying drawing explanation
Fig. 1 is the circuit logic diagram of the utility model pithead autoalarm;
Wherein: 1.PLC, 2. control button, 3. alarm lamp, 4. sensor, 5. cage chair, 6. safety door.
Detailed description of the invention
In order to deepen, to understanding of the present utility model, to be further described the utility model below in conjunction with embodiment and accompanying drawing, this embodiment, only for explaining the utility model, does not form the restriction of the utility model protection domain.
Describe preferred implementation of the present utility model in detail below in conjunction with accompanying drawing 1: a kind of pithead autoalarm, comprise PLC1, control button 2, alarm lamp 3, sensor 4; The mouth of described PLC1 connects cage chair 5 and the safety door 6 on pithead limit; The switch that described control button 2 controls the safety door 6 of pithead closes; Described alarm lamp 3 shows pithead cage chair 5 and is elevated; Whether described sensor 4 shows safety door 6 and puts in place.The PLC1 control setup adopted in the utility model is MCS51 micro controller system.In the utility model, control button 2 is connected with safety door 6 single line of pithead.Sensor 4 described in the utility model is well head safe door sensor.
The signal sent by getting room button ready interlocks with the safety door and cage chair program grasping car.Adopt the singlechip technology of technology maturation simultaneously, decrease cost and drop into.Control button is connected the switching that can realize automatic and manual operation and control with the safety door single line of pithead, decreases equipment investment, saves labour cost, effectively reduces service expenditure, improve work efficiency after changing.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
