Abstract

The utility model discloses an electrical control device of a rotary drilling rig, which includes a main controller, an engine controller, an electrical control pump valve, a deep measuring sensor, a tilt sensor, an oil level sensor, a pressure sensor and a display, wherein the sensors are connected with an input end of the main controller respectively; the engine controller, the display and the electrical control pump valve are connected with an output end of the main controller respectively; and the deep measuring sensor is a pulse encoder mounted on a steel wire rope roller rotating shaft of the rotary drilling rig. The electrical control device of the rotary drilling rig overcomes the technical defect that the power distribution is unreasonable in the prior art, resulting in low working efficiency, and enables the machine system, the electric system and the liquid system of the rotary drilling rig to operate in a coordinating manner.

Description

The rotary drilling rig electric control gear

Technical field

The utility model relates to a kind of rotary drilling rig electric control gear, belongs to engineering machinery piling machinery rotary digging drilling hole equipment electric-control system field.

Background technology

Rotary drilling rig at present each system works alone, and motor and hydraulic system work alone separately, oil consumption greatly, be prone to the car that goes out, when doing compound action power distribution unreasonable, cause inefficiency.

The utility model content

The utility model technical problem to be solved provides and a kind ofly can improve former rotary drilling rig controlling level, makes that rotary drilling rig is mechanical, electrical, the liquid systems co-ordination, improves navigability, energy-saving and cost-reducing rotary drilling rig electric control gear.

In order to solve the problems of the technologies described above, the utility model provides following technical scheme:

The rotary drilling rig electric control gear; Wherein rotary drilling rig comprises motor and hydraulic oil pump; Said rotary drilling rig electric control gear comprises the engine controller of master controller, corresponding connection with motor, automatically controlled pump valve, depth sensor, be located at obliquity sensor in the drilling rod, be located at the hydraulic oil pump place fuel level sensor, be located at automatically controlled pump valve place pressure sensor, be located at the display in the driver's cabin; Said each sensor links to each other with the master controller input respectively; Engine controller, display, automatically controlled pump valve link to each other with the master controller output respectively, and said depth sensor is mounted in the pulse coder in the rotating shaft of rotary drilling rig wire rope drum.

Fuel level sensor, pressure sensor, automatically controlled pump valve are set (can be known by common practise; The controlling unit that belongs to hydraulic system pressure output) be for hydraulic system is carried out sensing control; It is for motor is controlled that engine controller is set; It is to be convenient to operator to understand drill bit drilling depth, drilling rod inclination data that obliquity sensor, depth sensor, display are set, thereby carries out bore operation.

Use the utility model that following technique effect is arranged:

Through fuel level sensor, pressure sensor; Master controller can obtain the status data of hydraulic system; Yet master controller reaches the reasonable distribution of power again through control engine controller, automatically controlled pump valve, realizes that automatically rotary drilling rig is mechanical, electrical, the co-ordination of liquid systems; Do not influence simultaneously the normal running of operator.

Description of drawings

Fig. 1 is the structured flowchart of the utility model.

The arrow expression signal flows among the figure.

The specific embodiment

As shown in Figure 1; The rotary drilling rig electric control gear; Wherein rotary drilling rig comprises motor and hydraulic oil pump; Said rotary drilling rig electric control gear comprises the engine controller of master controller, corresponding connection with motor, automatically controlled pump valve, depth sensor, be located at obliquity sensor in the drilling rod, be located at the hydraulic oil pump place fuel level sensor, be located at automatically controlled pump valve place pressure sensor, be located at the display in the driver's cabin; Said each sensor links to each other with the master controller input respectively; Engine controller, display, automatically controlled pump valve link to each other with the master controller output respectively, and said depth sensor is mounted in the pulse coder in the rotating shaft of rotary drilling rig wire rope drum.

Engine controller and master controller are selected the EPEC2024 type controller for use, and display adopts the very color display of B&R 4PP480 type, and automatically controlled pump valve can be selected 4 road or the 8 tunnel automatically controlled pump valves that commutate for use.

Above-described only is the preferred implementation of the utility model; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement; These also should be regarded as the protection domain of the utility model, and these can not influence effect and practical applicability that the utility model is implemented.
