Force sensing lifting equipment and control method

Abstract

The invention discloses force sensing lifting equipment and a control method, the lifting equipment comprises a winch assembly, a force sensing handle assembly and a cable, the two ends of the cable are connected with the winch assembly and the force sensing handle assembly respectively, and a hanging assembly is connected to the force sensing handle assembly; the winch assembly comprises a winch controller, a winch motor, a motor driver and a first wireless module, the winch controller is electrically connected with the motor driver and the first wireless module, and the motor driver is electrically connected with the winch motor; the force sensing handle assembly comprises a handle controller, an unlocking module, a gravity sensor, an operating force sensor and a second wireless module, the handle controller is electrically connected with the unlocking module, the gravity sensor, the operating force sensor and the second wireless module, and the first wireless module and the second wireless module are in communication connection. According to the invention, the motion trend of the heavy object is consistent with the operation intention under low power consumption, a redundancy control method is considered, and the operation convenience of the lifting equipment is improved.

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to a force induction lifting equipment and a control method. Background technique [0002] The most common lifting device in the prior art is an electric hoist, which requires one hand to control the heavy object and the other to control the handle when operated by a single person. When it is necessary to control the heavy objects for fast and precise operation, the lifting speed of the heavy objects cannot be adjusted steplessly, which is very inconvenient to operate. For example, when lifting a heavy shaft, it is difficult to perform precise operation when the shaft needs to be inserted into a hole, and there is a possibility of damage to the shaft and the hole. [0003] In the prior art, there is another hoisting device with a stepless speed control handle, which uses a wired connection to connect the handle and the motor, and there are still many shortcomings: 1. The ...

Problems solved by technology

When it is necessary to control heavy objects for fast and precise operation, the lifting speed of heavy objects cannot be adjusted steplessly, which is very inconvenient to operate

For example, when lifting a heavy shaft, it is difficult to perform precise operations when inserting the shaft into a hole, and it may damage the shaft and the hole

[0003] In the prior art, there is also a lifting device with a stepless speed control handle, which uses a wired method to connect the handle and the motor, and there are still many disadvantages: 1. The wire is easy to collide with the cable, which affects the lifting movement of the lifting device, and the long-term up and down movement , the wires are easily damaged

2. Due to the existence of wires, it is difficult to realize the free rotation of the operating handle, which limits the range of up and down operation, and the handle cannot run too close to the motor, nor can it be too far away from the motor

4. It is inconvenient to operate the handle when the heavy object is lifted high, and there is a lack of redundant control design. Considering the method of redundant control from the perspective of the control system is also an important way to increase the convenience of operating the equipment system
