Embodiment Construction
[0018] The present invention will be described in detail below with reference to the drawings and embodiments.
[0019] figure 1 Shown is the installation diagram of the pressure signal acquisition device and the reel forward and reverse detection device of the present invention.
[0020] The invention is applied to a lifting mechanism with a hydraulic shift transmission. The lifting mechanism includes an electric motor 1, a hydraulic shift transmission 2, a pressure signal acquisition device 3, a reducer 4, a brake 5, a reel 6, and a reel Forward and reverse detection device 7. Compared with the conventional lifting mechanism, this lifting mechanism is provided with a hydraulic shift transmission 2 between the electric motor 1 and the reducer 4, and a pressure signal acquisition device 3 is added on the hydraulic shift transmission 2. A set of reel forward and reverse detection device 7 is added to the tail of the reel.
[0021] The control system of the present invention includes...
