Multi-point flexibly-driven stepless speed change winding device

Abstract

The invention relates to a multi-point flexibly-driven stepless speed change winding device. In the device, a main drive controller is connected with one end of a single-tube gear shift mechanism through a main input central wheel, and the end of the single-tube gear shift mechanism is in transmission connection with a single-tube planetary drive mechanism; the single-tube planetary drive mechanism is fixed on the main drive controller through a fixing shaft and in transmission connection with a winding drum; the other end of the single-tube gear shift mechanism is connected and fixed on a multi-point drive unit on a right bracket through an auxiliary input central wheel; and the multi-point drive unit is respectively connected with more than one group of auxiliary drive controllers with auxiliary drive motors. The powers of the main drive controller and the auxiliary drive controllers are merged through the gear shift mechanism and then used for driving the winding drum to work through a multi-stage planetary drive mechanism, and the stepless speed regulation of the winding device is realized through controlling the rotating speeds, the rotating directions and the flows of the main drive motor and the four drive motors and slowly pressurizing respective controllers; and the precise compensation of the tensile force and the speed of the winding device is realized through the individual control or the centralized control of the four auxiliary drive controllers.

Description

technical field [0001] The invention relates to a hoisting device, in particular to a hoisting device with multi-point flexible drive and stepless speed change. The hoisting device can be widely used in fields such as offshore construction, scientific research and investigation, and offshore platforms. Background technique [0002] The traditional hoisting device adopts the motor to drive the reel through the transmission device through the reducer to achieve hoisting. Most of the transmission structure adopts planetary transmission or planetary gear transmission with small tooth difference.

Problems solved by technology

With the changes in the use of the winch device, when different hoisting speeds and hoisting forces are required, the single motor, reducer and transmission structure cannot be adjusted in time when the pulling force and speed need to be adjusted at any time during operation. Stepless speed regulation is not possible, such as replacing different types of hoisting devices, repeated investment, high cost of use, inconvenient replacement, and a large storage space for multiple hoisting machines

[0003] China Patent No. 93226678.2 discloses a stepless speed regulating hoist. According to the principle of planetary transmission with few teeth differences, the hoist changes the output shaft from a fixed static connection to a rotatable connection of the output shaft, and adds a power speed regulating wheel to a fixed connection with the output shaft. Use the belt clutch mechanism to control the rotation and static conditions of the power flywheel and the unequal speed, so as to achieve the purpose of steplessly changing the speed of the reel that rotates in the opposite direction. The disadvantage is that the power flywheel adjusts the speed Restricted within the specification range of the motor, the maximum output speed of the hoist depends entirely on the specification of the motor. The range is relatively small; if the motor with a larger specification is replaced to adapt to the reel adjustment speed in a wide range, the overall weight will increase, the production cost will be relatively increased, and the installation space of the reel will be increased, and transportation and installation will be inconvenient
