(II) the use method of the lifting appliance system with the auditory and tactile prompting functions comprises the following steps:

Specifically, in the stimulus prompting the operation, the auditory stimulus of the alarm 6 is prompted by a "dripping" sound, the frequency of which and the spatial vertical distance information h between the hook 105 and the object to be hung, amplified by the signal amplifier 4₁Become negatively correlated, i.e. data h₁The larger the frequency of "drips" from the alarm 6. When data h₁When the value is within the error range, i.e. when h₁At values less than 50mm, the auditory stimulation ceases. The auditory stimulation frequency is adjustable from 300HZTo 1500 HZ. The controllable range of the spatial vertical distance is 1200 mm. The auditory stimulus frequency is inversely related to the spatial vertical distance, and when the spatial vertical distance between the hook 105 and the object to be hung reaches 1200mm, the auditory stimulus is triggered, and the frequency is 300 HZ.

The tactile stimulation positions are adjustable and respectively correspond to the ten fingers of the left hand and the right hand of the operator 8. When the hanger is positioned on the left side of the heavy object, the signal amplifier 4 amplifies the spatial transverse distance information h between the lifting hook 105 and the object to be hung₂Positive, the left finger is subjected to vibration stimulation, and the vibration stimulated finger and data h₂The size of (c) is related to: data h₂Maximum time when the left little finger is stimulated, data h₂At the minimum, the left thumb is stimulated; when the corresponding finger is stimulated, the control operating rod 701 moves a corresponding distance to enable the hook 105 to accurately hook the hanging ring 202. When the spreader is located on the right side of the weight, data h₂Negative, when the right finger is stimulated by vibration, the stimulation is similar to the left hand. When h is generated₂At values less than 10mm, the vibration stimulation was stopped.

The controllable range of the spatial transverse distance is 600 mm. When the sling is positioned on the left side of the weight and reaches 600mm, the touch stimulation is triggered and acts on the left thumb. When the hanger is positioned on the left side of the weight and the distance reaches 500mm, the touch stimulation is triggered and acts on the left ring finger. And by analogy, when the distance between the hanger and the left side of the weight reaches 200mm, the touch stimulation is triggered and acts on the left thumb. The right hand stimulation is similar.

Frequency of tactile stimulation and spatial longitudinal distance information h between the hook 105 and the object to be hung₃Become negatively correlated, i.e. data h₃The larger the frequency the slower. When the data value h₃Within the error range, i.e. when h₃At values less than 50mm, the vibration stimulation was stopped.

The tactile stimulation frequency is adjustable from 50HZ to 300 HZ. The controllable range of the spatial longitudinal distance is 1000mm, and the tactile stimulation frequency is inversely related to the spatial vertical distance. When the spatial longitudinal distance of the hook 105 from the object to be lifted reaches 1000mm, the tactile stimulus triggers with a frequency of 50 HZ.

In conclusion, the laser displacement sensor 3 is arranged on the lifting appliance, so that the distance between the lifting appliance and an object is measured. The laser displacement sensor 3 transmits the distance information to the signal amplifier 4 through an RS485 interface, and the distance information is amplified and then directly connected to the controller 5 through a USB to realize control. The controller 5 analyzes and processes the data and prompts auditory stimulation and tactile stimulation through the alarm 6 and the vibrating glove 7. The user can move and position the spreader device 1 via the joystick, the amount of movement of which is again registered by the laser displacement sensor 3 to form a closed loop system.

The lifting appliance system can provide corresponding auditory and tactile stimulation prompts in real time according to the spatial positions of the lifting appliance and the object to be lifted, so that the operator 8 can conveniently judge the spatial position relation between the lifting appliance and the object in real time, the lifting efficiency and accuracy are improved, the full-day operation is supported, the visual judgment of the operator 8 can be enhanced in the daytime, and the visual limitation can be made up at night. And the triggering mode and the prompting effect of the stimulation are related to the spatial position relation of the lifting appliance and the object. Auditory stimulation can not only prompt the position relation, but also early warn the false collision operation.

Although the present invention has been described in detail in this specification with reference to specific embodiments and illustrative embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made thereto based on the present invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
