Compact Structure And Light Weight Sinking Winch Conveying Hoisting Machine
1. Features of sinking winch conveying hoisting machine:
The static tension difference is large, the lifting load changes greatly, the lifting speed changes greatly during the sinking, the speed diagram is complex, which is at least nine stages of the speed diagram, which requires the lifting machine to have higher control precision and better speed performance; After the well sinking winch needs to be transported to other places for drilling, requiring compact structure, light weight, easy disassembly and handling, disassembly parts have enough stiffness, easy to install again.

3. Structure overview of sinking winch conveying hoisting machine
The structure of this series winch is winding type, which is mainly composed of spindle device, reducer, elastic coupling with brake wheel, working brake, safety brake, frame, motor and other parts.
(1) Spindle device
Spindle device includes: spindle, gear, drum, brake wheel, bearing seat and bearing, etc. The drum is connected with the gear and the brake wheel by the copper sleeve and bolt, and the gear is connected with the main shaft by the key, so the main shaft only rotates with the drum and does not transfer torque. The exit direction of the wire rope is up.
(2) reducer
Reducer is the use of spherical worm gear pair deceleration, plus a change gear. Change the fast and slow position of the gear change handle, which can change the fast and slow two speeds. Double-barrel 10-ton winch has a set of differential system, the differential handle is placed in the straight-through position, the speed of the two gears of the output shaft of the reducer is identical; If the differential handle is placed in the differential position, the two gears can produce relative rotation, that is, differential action.
(3) Working brake
Working brake using tile type brake, start the motor, electro-hydraulic actuator to loosen the brake, stop the motor is spring force brake.
(4) Safety brake
Full brake for tile floating type, by the weight of the hammer down for braking, electrohydraulic actuator loose brake.
4. Folding winch lubrication of sinking winch conveying hoisting machine
(1) The reducer shall be lubricated with winter HL-20 gear oil or HG-24 saturated cylinder oil, and its oil surface shall ensure that the worm is fully immersed in oil. The reducer is used once a year to change the oil.
(2) The bearing of the spindle and the bearing of the output shaft end of the reducer should be replaced regularly or supplemented with No. 4 calcium-based grease, and the oil should be changed once every two years.
(3) Lubricating oil should be added to the open gear before each start.
(4) The remaining parts to be lubricated should be lubricated before each start, especially the thrust ring between the two gears on the output shaft of the reducer and the shaft sleeve of the movable gear should be lubricated.
