Embodiment 1

[0056] This embodiment provides a force-sensing motion self-following lifting device, and its structural schematic diagram is as follows figure 1 and figure 2 As shown, it includes a power unit 1, a sheave mechanism 2, a Bowden wire 3, an induction mechanism 4 and a spreader 5 from top to bottom.

[0057] Such as image 3 As shown, the power unit 1 includes a servo motor 11 , a motor flange 12 , an encoder 13 , a reducer 14 , and a mounting plate 15 . The servo motor 11 is connected to the reducer 14 through the electrode flange 12 , the encoder 13 is installed in the slot hole of the electrode flange 12 , and the mounting plate 15 is installed on the reducer 14 for fixing the power unit 1 .

[0058] Such as Figure 4 As shown, the sheave mechanism 2 includes a first sheave housing 21, a drive shaft 22, a first bearing 23, a first spacer 24, a sheave 25, a Bowden wire limiter 26, a second spacer 27, The second bearing 28 , the damping wheel 29 , the second sheave shell 21...

Embodiment 2

[0061] In the following, some specific actions of a force-sensing motion self-following lifting device will be combined to illustrate the lifting and assisting process of the present invention through the working principle.

[0062] Hook the sling 5 on the heavy object, and the tension sensor 418 can measure the weight of the heavy object. When the operator holds the outer cylinder 42 with his hand and applies a little force upward, the fixed plate 414 will squeeze the spring 412, changing the pressure sensor 415. The pressure value, the control board 44 intelligently recognizes the collected sensor data, calculates the size and direction of the lifting power of the device, drives the servo motor 11, and then drives the sheave 25 to rotate, pulls the inner core 31 of the Bowden wire to transmit the torque to the spreader 5 Assist to achieve the purpose of hoisting heavy objects.

[0063] The present invention mainly has the following technical characteristics:

[0064] The tr...

Abstract

The invention belongs to the technical field of lifting equipment, and particularly relates to a force-sensing motion self-following lifting device. The force-sensing motion self-following lifting device comprises a power unit, a rope wheel mechanism, a Bowden cable, a sensing mechanism, a lifting appliance and the like. According to the force-sensing motion self-following lifting device, a sensor is arranged in the handheld sensing mechanism, the tiny up-and-down movement of an outer cylinder of the sensing mechanism is converted into a digital signal to be transmitted to a control unit, the control unit adopts a real-time motion control algorithm, intelligent recognition is carried out on collected sensor data, the size and the direction of lifting assistance of the device are calculated, then a motor in the power unit is driven to rotate forwards and reversely, the Bowden cable is pulled to transmit torque to the lifting appliance, and therefore the purpose of lifting a heavy object is achieved through motion following of the lifting appliance. The force-sensing motion self-following lifting device has the advantages of being simple in structure, small in size, smooth in transmission and timely in assistance, the labor intensity of a human body during operation can be reduced, and the working efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of hoisting equipment, and in particular relates to a force-sensing motion self-following hoisting device. Background technique [0002] In production operations, the lifting device, as a commonly used material lifting equipment, uses a lifting mechanism to quickly transfer materials from a low position to a high position, thereby replacing human labor. Short-distance, high-frequency, intensive lifting operations in parts assembly, warehouses, docks and other occasions. [0003] Patent document CN 110155887 A discloses a small lifting device, including a moving assembly, a rotating assembly, a column assembly, a lifting assembly, and a handling assembly. The rotating assembly is arranged on the upper part of the moving assembly and connected to the bottom of the column assembly. On the upper part of the column assembly, the conveying assembly can be adjusted and arranged on the lower part of the column asse...
