4, the control system in the electric control box is a CANopen fieldbus structure, makes electrical control system more reliable; Simultaneously controller is selected control computer PC C for use, combines the technical advantage of PLC and Industrial PC, and as high reliability and the timer clock of PLC, the multitask running of PC, high-speed computation power, good autgmentability are communicated by letter etc. with open.Simultaneously, the PCC controller adopts the operating system of the qualitative TCM of Runtime.If have reliable sensors, use the just easily realization of memory cut function of high-level language like this.During actual the use, the PCC controller can be realized required powerful data-handling capacity of coal-winning machine automation and abundant ability to communicate, and system has good antijamming capability, has improved the reliability of coal-winning machine electrical system greatly.In addition, contactor of the present invention and isolating switch dependable performance guarantee coal-winning machine non-failure operation time effectively.
5, the gear clutch of rocking arm is simple in structure, reasonable in design and result of use is good, especially is suitable for the needs of girdle coal mining.In the actual use, owing to be applicable to the geological conditions in girdle coalfield, the rocking arm power of institute's employing coal-winning machine is big, compact conformation, if adopt traditional gear clutch structure, owing to be subjected to structural limitations, the size of sliding pin can't be amplified, in coal-winning machine coal cutting process, when the cylinder coal cutting was subjected to impacting, sliding pin was often cut off by the axes of inertia, influenced coal-winning machine and normally mined; And the present invention is by being provided with dive key between axle and driven pulley; when the start and stop of low seam mining machinery rocking arm or when being subjected to shock loading; bear additional load by dive key; therefore can effectively avoid coal-winning machine in operation process, to cause sliding pin to be cut off the generation of phenomenon, also improve the functional reliability of gear clutch simultaneously greatly by axle because of rocking arm is hit.

7, water-cooling pattern is adopted in the motor cooling, and water-cooled type frequency convertor is housed on the water cooled pipeline, and the laying mode of motor cooling pipe and motor electricity cable is very reasonable simultaneously.Because employed coal-winning machine requirement cut power was big during deeply exploited in the girdle coalfield, but be limited to the restriction of working face of coal seam again; the cutting motor of being adorned on the rocking arm can not the too big motor of power to the coal-winning machine height; and in order to satisfy the requirement of coal-winning machine cut power; the method that high-power low seam mining machinery adopts a rocking arm that two cutting motors are installed increases cut power, but this wiring for motor electricity cable and cooling pipe has proposed a difficult problem.Among the present invention; all motor electricity cables and motor cooling pipe are all laid along the rib side (being the side of coal-winning machine fuselage near rib) of coal-winning machine; like this, it is convenient protected not only to lay good motor electricity cable and cooling pipe, and has significantly reduced the pipeline quantity of old man's side.Simultaneously, be connected to the motor electricity cable of cutting motor can be easy with two cutting motor strings together, the wiring circuit is simple and be easy to protection.In addition, because the machine height of low seam mining machinery is low, fuselage is narrow, causes the pipeline extruding easily in the wiring of old man's side in the past, is difficult for protection, and influences workman's operation.Among the present invention, motor electricity cable and cooling pipe are all protected under backplate, have significantly reduced the pipeline of coal-winning machine fore side, are easy to individual's operation, have prevented that effectively motor electricity cable and cooling pipe from being smashed by coal cinder or stone when coal-winning machine moves.
8, the reasonable in design of tractive unit planetary reduction gear and result of use are good, and input cost is low, the actual demand of especially suitable girdle coalfield coal-winning machine.Because the exploitation in domestic thin layer complicated geological coal seam needs, the structure of used coal-winning machine is little and power is big, thereby the moment of torsion that the planetary reduction gear of axis of traction output need bear is big, because the self structure requirement, planetary reduction gear is restricted in size radially, wants to meet the demands on intensity, just must strengthen the facewidth of planetary gear, the corresponding planet wheel spindle axial dimension lengthening that makes, but according to traditional four lines star wheel structure, the rigidity of planet wheel spindle and intensity are difficult to guarantee.The present invention has then increased support together by set up the gripper shoe of putting more energy on planet carrier to planet wheel spindle, has improved the rigidity and the intensity of planet wheel spindle.
Simultaneously, because the radial dimension of planetary reduction gear is restricted, the built-in bearing load of planetary gear is big, thereby existing self-aligning roller bearing has not satisfied actual needs in size and carrying.Thereby, among the present invention the secondary planet wheel bearing is adopted special full type roller bearing, self is not with the outer ring this bearing, the planetary gear inwall is a bearing outer ring ball track, so just having saved transmission self-aligning roller bearing outer ring takes up space, satisfying under the prerequisite of intensity, reduced the physical dimension of planetary gear greatly.
In sum, reasonable in design of the present invention, complete machine power is big, production efficiency is high and stable and reliable working performance, result of use are good, can solve effectively that the power that existing coal-winning machine exists is less, production efficiency is low, result of use is relatively poor in the thin seam mining process, have a strong impact on multiple practical problem such as China's girdle complicated geological coal mining work.
