[0004]In view of these advantages of the electric drum, it can replace the widely used external driving device in the form of a motor and a reducer, and is applied in various industries. Among them, "JB / T 7330-2008 Electric Drum" stipulates that the length of the roller surface of the drum is based on 250 mm, and the increment is incremented by 50 mm. It can be seen that due to the wide range of applications, there is a need for the length of the electric drum with the same diameter. A large number of specifications has caused great trouble to the production of electric drums. On the premise that the customer has not determined the length of the drum, the manufacturer cannot determine the processing drum. This situation has caused the manufacturer to be unable to prepare goods in advance, and the demand side cannot Receive the finished electric drum in a short time, but once the manufacturer receives the order, it needs to work overtime for production. If there is no order, the production cannot be organized, resulting in waste of resources and unreasonable labor arrangements.

Embodiment 2

[0047] Embodiment two:

Embodiment 3

[0049] Embodiment three:

[0050] On the basis of Embodiment 2, in the magnetic field generating device 802, the permanent magnet and the magnetic base are replaced by coils. The pre-assembled wire conduit 16 is inserted into the mandrel 10 to form the assembled wire conduit 7. When the coil is charged, the magneto-rheological locking sleeve 801 can be changed into a quasi-fixed shape to realize the locking of the extension tube.

Abstract

The invention discloses a permanent magnet electric drum for mines. The electric drum includes: a power cylinder, the power cylinder is an outer rotor permanent magnet motor, one end of the permanent magnet motor is provided with a speed reduction mechanism, and the stator of the permanent magnet motor is provided with Hollow mandrel, the wire in the motor is connected to the outside through the hollow mandrel from the end without the deceleration mechanism, and the output shaft end of the deceleration mechanism is provided with a connecting device; the extension cylinder, the diameter of the outer cylindrical surface of the extension cylinder is the same as the outer diameter of the power cylinder The diameters of the cylindrical surfaces are the same, and one end of the mandrel of the extension cylinder is provided with a plug-in device matched with the connection device, and the other end is provided with the connection device, a connector, a connection device for connecting the extension cylinder and a connection device for the power cylinder. The beneficial effect of the invention is that the traditional structure of the electric drum is changed, the length of the electric drum can be freely adjusted and combined, it is convenient for the manufacturer to prepare goods and organize production, and it is convenient to realize the application of belt conveyors of different widths.

Description

technical field [0001] The invention belongs to the technical category of an electric drum length adjustment device in the technical field of electric drums, and in particular relates to a permanent magnet electric drum for mines and an assembly method thereof. Background technique [0002] The electric drum is a new type of driving device that puts the motor and the reducer inside the drum body. It is mainly used in fixed and mobile belt conveyors, replacing traditional motors, and the decelerator is a separate drive device outside the drive roller. [0003] The electric drum has many advantages such as compact structure, high transmission efficiency, low noise, long service life, stable operation, reliable operation, good sealing, small space occupation, convenient installation, etc., and is suitable for working in various harsh environmental conditions. [0004] In view of these advantages of the electric drum, it can replace the widely used external drive device in the ...
