Abstract

The invention discloses a lifting driving device for a wire installation pay-off device. The lifting driving device comprises a bottom fixing baseplate. The lifting driving device couples with a support for the wire installation pay-off device, a power transmission line in a hoisting wheel can neutralize the friction force required by rotation when the end of the power transmission line is pulled,the wire can be subjected to rotation pulling under the premise of low pulling force, and the self-adaptability is improved. The phenomenon of the loosened wire cannot occur, the lifting driving device can control the maximum resistance of rotation, and the phenomenon that the hoisting wheel rotates since the hoisting wheel does not have pulling force is avoided. The lifting driving device is provided with a reverse-thread-structure rotation-type vertical height limit mechanism and can move synchronously with the support for the wire installation pay-off device so as to achieve coupling, in addition, the lifting driving device is provided with a rotation shaft fixing-type part connection mechanism and can achieve a fixing limit function on the rotation shaft and achieve a mounting fixingfunction on the part.

Description

technical field [0001] The invention relates to the technical field of electric power installation, in particular to a lifting drive device for a wire installation pay-off device. Background technique [0002] At present, in the electric power installation site, a pay-off device is needed. The existing pay-off device is driven by a drive motor for rotation. This pay-off device has poor adaptability and requires manpower control. Once the wire is stopped due to traction, the drive motor Continued rotation will often result in loose wire payouts. Contents of the invention [0003] The object of the present invention is to provide a lifting drive device for a wire installation pay-off device to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solution: a lifting drive device for a wire installation pay-off device, including a bottom fixed base plate, a...
