[0002] The cleaning chain of the coal feeder is generally installed at the bottom of the weighing coal feeder to clean the coal accumulated at the bottom of the coal feeder body, so as to ensure the normal operation of the coal feeder. During the maintenance work, when replacing the cleaning chain of the coal feeder, it is necessary to rotate the cleaning chain motor so that the cleaning chain can exit the cylinder. The original manpower is very dangerous when pulling through the fall chain. When the motor is manually rotated with an adjustable wrench, it is easy to damage the motor and there is a risk of injury to personnel. When the motor is manually rotated, the working position is very small, and the workload of a single person is large. Multiple people must be assigned to supervise and replace the work at the same time, which consumes a lot of time and manpower. Utility Model Content

[0004] To achieve the above-mentioned purpose, the utility model provides a winching device for a cleaning chain motor, characterized in that it includes: a sleeve, a crank and a crank handle, the main shaft of the cleaning chain motor is inserted from one end of the sleeve, the other end of the sleeve is detachably connected to one end of the crank, the other end of the crank is connected to the crank handle, and the crank is Z-shaped; a plurality of bolts are arranged on the outer periphery of the sleeve, each bolt is connected to a rotatable nut, and the bolts and the rotatable nuts are used to fix the main shaft of the cleaning chain motor.
[0005] Furthermore, the crank handle is parallel to the sleeve axis.
[0006] Furthermore, a plurality of through holes are arranged on the outer circumference of the sleeve, the through holes are adapted to the bolts, and the bolts are passed through the through holes.
[0007] Furthermore, the rotatable nut is arranged on the outer periphery of the sleeve.
[0008] Furthermore, two bolts are arranged on the outer periphery of the sleeve, and the two bolts are symmetrically arranged up and down about the axis of the sleeve.
[0009] Furthermore, the sleeve has a caliber of 25 mm and a length of 40 mm.
[0010] Furthermore, the bolt has a diameter of 10 mm.
[0011] Furthermore, the axial extension line of each bolt is perpendicular to and intersects with the axis of the sleeve.
[0012] Furthermore, the cleaning chain is made of carbon steel.
[0013] The beneficial effects of the utility model are as follows: by fixing the sleeve and the main shaft of the cleaning chain motor and shaking the crank handle, the sleeve is driven by the crank to rotate the motor to replace the cleaning chain, which can effectively shorten the replacement time of the coal feeder cleaning chain, and a single person can complete the turning work, which is light and fast. The crank handle is set to a Z shape, so that the operator has a safe distance from the motor to avoid personal injury. BRIEF DESCRIPTION OF THE DRAWINGS
