The drive system is characterized in that: the system adopts an AC variable frequency speed control cage induction motor, wherein the rear part of a cabinet body of a variable frequency speed control is provided with an annular heat pipe radiator, while the top is provided with a vertical heat pipe radiator and the bottom is provided with a damping module; an on-load switch, an electrical element, a frequency conversion control board and an IGBT module which are arranged inside the cabinet body are connected with the annular heat pipe radiator arranged at the rear part of the cabinet through a plaque; moreover, the vertical heat pipe radiator is fixed at the top of the cabinet body through the plaque. The utility model has the advantages that: the protection degree of the system reaches IP54, which solves the problem of frequent failure of an electrical motor; moreover, heat dissipation of the power electronic device and other electric elements arranged inside a control cabinet is completed through the heat pipe radiator, thereby obtaining low failure rate and increasing the work efficiency of a drill and the service life of a drill bit.
Description
Technical field
The utility model relates to the revolution driving control system of the rotary drill of metallurgical mine use.
Background technology
Rotary drill is the main perforating apparatus that present metallurgical mine uses, and rig revolution dc drive system is the weakest link of rig, the equipment failure rate height, put down in writing according to interrelated data, 2 in the average moon replacing of every bench drill machine motor adds the control system fault, and equipment operation rate is lower.
The main cause that its fault takes place frequently is that the rig electric drive system can not adapt to the abominable operating environment of rig, the environment of rig operation is open work, the ore dust that produces during its work fills the air, because the degree of protection of existing switch board and direct current generator is low, cause the control circuit short circuit, the engine commutator sparking, the armature winding burns out, accident takes place frequently, and influence is produced.
Summary of the invention
The purpose of this utility model provides a kind of mine rotary drill high-protection type ac digital transmission system, system adopts the ac variable frequency speed regulation cage induction motor, power electronic devices and other electrical equipment in the switch board dispel the heat by heat-pipe radiator, fault rate is low, improves the life-span of rig operating efficiency and drill bit.
Technology contents of the present utility model is described below:
Mine rotary drill high-protection type ac digital transmission system, comprise motor, RHVC, it is characterized in that: this system adopts the ac variable frequency speed regulation cage induction motor, the cabinet rear portion of its RHVC is provided with the annular heat pipe radiator, the top is provided with the vertical thermal tube radiator, the bottom is provided with the damping module, cabinet internal loading switch, electrical equipment, variable frequency control plate, IGBT module are connected with the annular heat pipe radiator at cabinet rear portion by substrate, and the vertical thermal tube radiator is fixed on the cabinet top by substrate.
Compared with prior art, the beneficial effects of the utility model are:
1) system adopts the frequency control cage induction motor, degree of protection reaches IP54, has solved the take place frequently problem of fault of motor;
2) power electronic devices in the switch board and other electrical equipment dispel the heat by heat-pipe radiator, realized that switch board is dustproof, the function of waterproof, anti-frosting, have solved the take place frequently problem of fault of motor;
3) vibration frequency and the amplitude of reduction device, damping, the shock resistance of raising device;
4) control the frequency control performance totally, adopt the power-type vector controlled, adapting to the process characteristic of rig, high starting torque, starting torque can reach 150% nominal torque; According to the variation of rig process conditions, automatically change the operational mode of frequency conversion, to satisfy the optimised process of rig, the life-span of improving rig operating efficiency and drill bit in different rock-layers boring.
