Commonly used in the mine tunnel in the haulage and supporting mine car handling、 can also be used in the mining face、 with scheduling space station、 heavy cars. Scheduling winch is fullgear transmission machinery. Gear also known as the round of the transmission system. According round of the transmission gear when the axis of space in the relative position is fixed、 can be divided into fixed and working capital of the axis round of the round. Another round of the axis of cylindrical mesh gear transmission and the cylindrical mesh gear transmission of points、 and turnover of another round of transmission and differential planetary transmission of the points. Scheduling the winch within the existing transmission gear meshing cylindrical Gear、 another planetary transmission、 scheduling winch planetary transmission gear、 also known as the winch. Scheduling winch models monly used mainly ()、 JD1 (JD) )、 JD1. (JD22)、 JD2 (JD25)、 JD3 (JD 40). Below the JD3 (that is、 JD40) as an example of scheduling winch on the position and scheduling transmission principle. (A) JD3scheduling of the winch JD3scheduling the main ponent of the winch drum for、 brakes and motor frame. From the winch drum made of cast steel、 its main function is winding rope traction load. Drum、 and the slowdown in gear with the gear. Winch on the two groups with a total installedgate that is Brake the gateway 3. Motor side of the gate 2 to brake drum brakes、 the gear in the work of three gates used to control Z7 group functioning. Use made of cast iron frame、 the motor bearings and gates with stentpositioning are fixed with bolts in the plane seat. For Flameproof for the theephase motor .(B) JD3Dispatch winch the drive principle this type of winch used two Internal Drives and a planetary gear transmission. Z1/Z2 and Z3/Z4 for two Internal Drive、 Z Z Z7 position of planetary transmission mechanism. Motor head in the installation of a 5axis extended sets of gear Z through the gears Z with gear Z3 and Z the movement spread to gear Z the Z5 is the planetary gear wheel of a central round (or round of the Sun) And then led the two planetary gear Z and the gear Z7. Planetary gear freely installed in the two driven and connected to a fixed axis、 the largest in the gear Z7 Gear work with the external gateway、 used to control winch drum operation. If the big gear Z7 gate on the work of three gates to live、 and will be on the brake drum gates 2 release、 this time by two motor rotation within the rodents to gear wheel drive Z Z6 and Z7. However、 due to Z7 gate has been living and can not rotate、 so gear Z6 only on the one hand around its own axis of rotation、 but also around the axis of gear Z5 (drum center) to the public. Thus connected with the rotation of the lead、 then Z6 the operation mode very similar to the planets in the solar system (such as Earth) movement、 also known as the planetary gear Z its transmission mode known as the planetary transmission. Conversely、 if the gear Z7 in the work release gate and will brake drum on the live gate the Z6 directly connected with the drum、 only for the rotation、 not revolution、 the Z1 from the transmission system changed to Z7 For the fixed axis of the round、 gear Z7 to go short. Inverted for the release (or live gate) gate work Brake 2 or you can make scheduling winch in the case of nonstop motor to achieve operating and parking. When the need to reverse upgrade、 must be reactivated the launch button、 reverse the motor running. It should be noted that、 when the motor is turned on、 the gate and not allowed to work Brake live gate at the same time、 it will burn motor or other accidents. Third、 scheduling winch daytoday maintenance check the contents of (1) check each part of bolts、 pin、 nuts、 washers、 etc.、 if loose、 loss should be tightened and timely plement. (2) to check installations and electrical signal Operation button is intact and whether stolen explosive phenomenon、 whether the signal sent clear and bright、 it should be repaired or replaced. (3) to check whether damaged or broken drum、 the first wire rope is firmly fixed、 bearing oil spill there、 the rope is neatly arranged、 the problems should be promptly dealt with. (4) inspection gate with a crackfree、 weargauge whether or not (should have a thickness of not less than 3 mm)、 the tension bar bolts、 fork first、 the gate、 such as whether there is a pin deformation or injury、 whether the loose nuts back tight、 Problems should be adjusted and dealt with. (5) Check the gate and lever action is a flexible system、 Shi gate、 the ate may not reach the level position、 it should be slightly Sangria than the horizontal position. (6) to check the roof fixed winchandbeam is solid、 based on whether there is a bolt or bolts
