Description

Technical Field

[0001] The present invention relates to a screw lift, and in particular to a screw lift with a multi-modal operation and interactive system applied in the technical field of lifts. Background Art

[0002] In most applications, the screw lift uses a motor to drive the screw to rotate, so that the threads on the screw interact with the nut to achieve the up and down movement of the lifting platform. The direction and speed of rotation of the motor can control the direction and speed of movement of the platform to achieve precise lifting and stopping. This operating mode is suitable for large-scale, heavy-load lifting needs, with higher efficiency and stability.

[0003] The specification of Chinese invention patent CN201921917205.0 discloses "A screw elevator", which can deliver products in or out through the conveyor belt on the lifting platform; the screw is rotated by the lifting motor to achieve the lifting of products on the lifting platform, which has the advantages of convenience and efficiency, while reducing labor costs.

[0004] Most of the existing electric screw lifts have the operating table installed on the lift workbench. Every time the staff performs the lifting operation of the lift, they will stop their work and come to the operating table to perform manual operation. Frequent lifting operations affect the work efficiency of the staff. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that each time the staff performs a lifting operation on the elevator, they will stop their work and go to the operating table to perform manual operation. Frequent lifting operations affect the work efficiency of the staff.

[0006] In order to solve the above problems, the present invention provides a screw lift with a multi-modal operation and interaction system, comprising a lift body, an electric lift group is fixedly connected to the middle of the lift body, a working platform is fixedly connected to the top of the lift body, an interactive platform is fixedly connected to one end of the working platform, a touch screen operating system is fixedly connected to the top of the interactive platform, and a wireless interaction module is included in the interactive platform, and the wireless interaction module includes a voice interaction system, a motion interaction system and a sensor interaction system;

[0007] The motion interaction system includes a left shoe ring assembly and a right shoe ring assembly. The outside of the left shoe ring assembly and the right shoe ring assembly are fixedly connected with a photosensitive circle. The input end of the motion interaction system is connected to a trajectory acquisition module. The output end of the trajectory acquisition module is connected to the electric lifting group, and the input end of the trajectory acquisition module corresponds to the photosensitive circle.

[0008] In the above-mentioned screw lift with a multi-modal operation and interactive system, the trajectory acquisition module on the motion interaction system sends lifting instructions to the electric lifting group by judging the movement changes of the photosensitive circles on the left shoe ring assembly and the right shoe ring assembly, thereby controlling the lifting movement of the lifting body, effectively shortening the time for manual operation of the lift, and freeing the hands of the staff, making it convenient for the staff to perform other work simultaneously, effectively improving work efficiency.

[0009] As a further improvement of the present application, light strips are fixedly connected to the inside of the two photosensitive circles, and the two sets of light strips are set with different colors. The light strips of different colors effectively improve the distinction effect of the two photosensitive circles, thereby effectively improving the collection accuracy of the trajectory collection module.

[0010] As a further improvement of the present application, a high-speed camera is connected to the input end of the trajectory acquisition module. The high-speed camera is fixedly installed in the middle of the interactive platform, and the acquisition end of the high-speed camera is facing the working platform. The high-speed camera accurately captures the foot movements of the workers on the working platform, effectively improving the accuracy of motion capture.

[0011] As a further improvement of the present application, an alarm unit is fixedly connected to the outside of the high-speed camera. The alarm unit is used to sound an alarm when the front of the high-speed camera is blocked. The output end of the alarm unit is connected to the voice interaction system. When the high-speed camera is blocked, the alarm unit will sound an alarm to the staff, effectively avoiding affecting the action interaction process.

[0012] As another improvement of the present application, the sensor interaction system includes a main sensing component for receiving sensor information, the input end of the trajectory acquisition module is connected to the timing acquisition module and the lifting start and stop module, the timing acquisition module is used to select the motion trajectory occurring in a specified time period, and the lifting start and stop module is used to control the start time and stop time of the elevator movement. The input ends of the timing acquisition module and the lifting start and stop module are both connected to the output end of the main sensing component. After the main sensing component is triggered, the timing acquisition module starts the action interaction timing, and the lifting start and stop module provides the starting time for the lifting work. The activities of the staff during the rest of the time will not affect the work of the elevator, which is convenient for the staff to move freely on the work platform. After the main sensing component is triggered again, the lifting start and stop module stops the lifting movement of the elevator.

[0013] As another improved supplement of the present application, the main sensing component is configured as a pressure sensor, and the external fixed sleeve of the main sensing component is provided with a cylindrical disc, which is fixedly installed in the middle of the left shoe ring assembly. The cylindrical disc provides protection for the main sensing component, and the main sensing component is triggered by pressure.

[0014] As another improvement supplement of the present application, the rear end of the right shoe ring assembly is fixedly connected with a secondary sensing assembly matching the main sensing assembly. The secondary sensing assembly is spherical, and the diameter of the secondary sensing assembly corresponds to the inner diameter of the cylinder disk. The staff kicks the left foot pit with the right heel to achieve pressure sensing of the main sensing assembly triggered by the secondary sensing assembly. The action is simple, convenient and fast.

[0015] As another improvement of the present application, the sensing end of the main sensing component is fixedly connected with a pressure rod, the pressure rod is sleeved with the barrel, and the outer end of the pressure rod corresponds to the secondary sensing component. The triggering operation of the main sensing component is achieved by squeezing the sensing end of the main sensing component by the pressure rod.

[0016] As another improvement supplement of the present application, a magnet block is fixedly connected to the outer end of the pressure rod and the inside of the secondary sensing component. The two magnet blocks are arranged to repel each other magnetically. A spring is fixedly connected between the magnet block and the main sensing component. The elastic force of the spring is smaller than the magnetic force between the two magnet blocks. The repulsive force between the two magnet blocks realizes the inductive interaction between the main sensing component and the secondary sensing component, effectively avoiding damage to the main sensing component caused by direct interactive collision.

[0017] As another improvement supplement of the present application, a protective cover is fixedly connected to the outer end of the barrel disc, the outer end of the pressure rod abuts against the inner side of the protective cover, the protective cover is concavely arranged corresponding to the secondary sensing component, and the protective cover provides closed protection for the main sensing component in the barrel disc, effectively improving the protection effect of the main sensing component.

[0018] To sum up, the present invention performs multiple modes of operation and interaction on the elevator through a voice interaction system, a motion interaction system and a sensor interaction system, thereby effectively improving the intelligent control effect of the elevator. The staff sticks the left shoe ring assembly and the right shoe ring assembly to their shoes respectively. When performing the lifting operation of the elevator, the staff only needs to select the left and right feet and make any movements. The trajectory acquisition module on the motion interaction system judges the movement changes of the photosensitive circles on the left shoe ring assembly and the right shoe ring assembly, and sends lifting instructions to the electric lifting group, thereby controlling the lifting movement of the lifting body, effectively shortening the time for manual operation of the elevator, and freeing the hands of the staff, making it convenient for the staff to perform other work simultaneously, thereby effectively improving work efficiency.

[0029] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0030] The first implementation method:

[0031] Figure 1-3 It is shown that a screw lift with a multi-modal operation and interaction system includes a lift body 1, an electric lift group 101 is fixedly connected to the middle of the lift body 1, a working platform 102 is fixedly connected to the top of the lift body 1, an interactive platform 2 is fixedly connected to one end of the working platform 102, a touch screen operating system 201 is fixedly connected to the top of the interactive platform 2, and a wireless interaction module is included in the interactive platform 2, and the wireless interaction module includes a voice interaction system, a motion interaction system and a sensor interaction system;

[0032] The staff climbs onto the work platform 102, performs traditional manual lifting operations by operating the touch screen operating system 201 on the interactive platform 2, sends voice commands to the voice interaction system, operates the elevator for lifting and lowering, and uses the motion interaction system and the sensor interaction system to operate the elevator for lifting and lowering, thereby realizing multiple modes of operation and interaction of the elevator, and effectively improving the intelligent control effect of the elevator.

[0033] Figure 3-5As shown, the motion interaction system includes a left shoe ring component 3 and a right shoe ring component 4, the outside of the left shoe ring component 3 and the right shoe ring component 4 are fixedly connected with a photosensitive circle 5, the input end of the motion interaction system is connected with a trajectory acquisition module, the output end of the trajectory acquisition module is connected to the electric lifting unit 101, and the input end of the trajectory acquisition module corresponds to the photosensitive circle 5, and the two photosensitive circles 5 are fixedly connected with light strips 501 inside, and the two groups of light strips 501 are set with different colors. The light strips 501 of different colors effectively improve the distinction effect of the two photosensitive circles 5, thereby effectively improving the acquisition accuracy of the trajectory acquisition module;

[0034] Before performing the action interaction of the elevator, the staff first sticks the left shoe ring assembly 3 and the right shoe ring assembly 4 to their shoes respectively. When the elevator needs to be lifted, the staff only needs to select the left and right feet and make any actions. For example, the staff stands on the right foot and swings the left foot back and forth, which represents the lifting instruction of the elevator. The light-sensitive circle 5 on the left shoe ring assembly 3 changes its moving trajectory. The trajectory acquisition module performs motion capture and acquisition of the trajectory movement change, thereby judging the movement changes of the light-sensitive circle 5 on the left shoe ring assembly 3 and the right shoe ring assembly 4, and sending an ascending instruction to the electric lifting group 101, thereby controlling the ascending movement of the lifting body 1. Conversely, the right foot swings back and forth and the elevator descends. The staff no longer needs to stop the work at hand, which is convenient for the staff to perform other work simultaneously, effectively improving work efficiency.

[0035] Figure 1-2 It is shown that the input end of the trajectory acquisition module is connected to a high-speed camera 6, which is fixedly installed in the middle of the interactive platform 2, and the acquisition end of the high-speed camera 6 faces the work platform 102. The high-speed camera 6 accurately collects the foot movements of the staff on the work platform 102, effectively improving the accuracy of motion capture. The outside of the high-speed camera 6 is fixedly connected to an alarm unit, which is used to alarm when the front of the high-speed camera is blocked. The output end of the alarm unit is connected to the voice interaction system. When the high-speed camera 6 is blocked, the alarm unit will alarm the staff to effectively avoid affecting the action interaction process.

[0036] The high-speed camera 6 is used to accurately capture the foot movements of the staff, effectively improving the accuracy of motion capture, and when the high-speed camera 6 is blocked, the alarm unit is used to give an alarm prompt to the staff, effectively avoiding affecting the action interaction process.

[0037] The second implementation method:

[0038] Compared with the first embodiment, this embodiment mainly adds a main sensing component 7, the specific new contents are as follows, and the rest of the structure is consistent with the first embodiment.

[0039] Figure 3 and Figure 6-7 As shown, the sensor interaction system includes a main sensing component 7 for receiving sensor information, the input end of the trajectory acquisition module is connected to a timing acquisition module and a lifting start-stop module, the timing acquisition module is used to select the motion trajectory occurring in a specified time period, and the lifting start-stop module is used to control the start time and stop time of the elevator movement, and the input ends of the timing acquisition module and the lifting start-stop module are both connected to the output end of the main sensing component 7. After the main sensing component 7 is triggered, the timing acquisition module starts to perform action interaction timing, and the lifting start-stop module provides a start time for the lifting work. The activities of the staff during the rest of the time will not affect the work of the elevator, which is convenient for the staff to move freely on the work platform 102. After the main sensing component 7 is triggered again, the lifting start-stop module stops the lifting movement of the elevator;

[0040] When the staff is performing interactive operations on the elevator, they first trigger the main sensing component 7 through foot movements. At this time, the timing acquisition module sets a time for capturing the next action, and the lifting start and stop module starts the lifting movement of the elevator. The action that occurs between three and four seconds after the main sensing component 7 is triggered is the captured action. During the rest of the time, the staff can move freely on the work platform 102. Subsequently, the main sensing component 7 is triggered again, and the lifting start and stop module stops the lifting movement of the elevator.

[0041] Figure 6-8 As shown, the main sensing component 7 is set as a pressure sensor, and the external fixed sleeve of the main sensing component 7 is provided with a cylinder disc 701, which is fixedly installed in the middle of the left shoe ring component 3, and the cylinder disc 701 provides protection for the main sensing component 7. The main sensing component 7 is triggered by pressure, and the rear end of the right shoe ring component 4 is fixedly connected with a secondary sensing component 702 matched with the main sensing component 7. The secondary sensing component 702 is spherical, and the diameter of the secondary sensing component 702 corresponds to the inner diameter of the cylinder disc 701. The staff member realizes the pressure induction of the secondary sensing component 702 triggering the main sensing component 7 by kicking the left foot pit with the right heel, and the action is simple, convenient and fast.

[0042] When performing the triggering operation of the main sensing component 7, the staff member stands on one foot and kicks the left foot arch with the right heel to realize the pressure sensing of the secondary sensing component 702 triggering the main sensing component 7. The action is simple, convenient and fast. At the same time, the cylindrical disc 701 is used to provide protection for the main sensing component 7, effectively avoiding damage to the main sensing component 7 during the kicking process.

[0043] Figure 6-8As shown, the sensing end of the main sensing component 7 is fixedly connected with a pressure rod 703, the pressure rod 703 is sleeved with the drum disc 701, and the outer end of the pressure rod 703 corresponds to the secondary sensing component 702, and the triggering operation of the main sensing component 7 is realized by squeezing the sensing end of the main sensing component 7 by the pressure rod 703, and the outer end of the pressure rod 703 and the inside of the secondary sensing component 702 are fixedly connected with a magnet block 704, the two magnet blocks 704 are arranged to repel each other by magnetic force, and a spring 705 is fixedly connected between the magnet block 704 and the main sensing component 7, and the elastic force of the spring 705 is less than the two The magnetic force between the two magnet blocks 704 realizes the inductive interaction between the main inductive component 7 and the secondary inductive component 702 through the repulsive force between the two magnet blocks 704, effectively avoiding the damage of the main inductive component 7 caused by direct interactive collision. The outer end of the barrel 701 is fixedly connected with a protective cover 706, and the outer end of the pressure rod 703 contacts the inner side of the protective cover 706. The protective cover 706 is concavely arranged corresponding to the secondary inductive component 702. The protective cover 706 provides closed protection for the main inductive component 7 in the barrel 701, effectively improving the protection effect of the main inductive component 7.

[0044] When the secondary sensing component 702 kicks the main sensing component 7, the magnet block 704 in the secondary sensing component 702 and the magnet block 704 on the pressure rod 703 repel each other magnetically, thereby compressing the spring 705, so that the pressure rod 703 applies pressure to the main sensing component 7, effectively avoiding damage to the main sensing component 7 caused by direct interactive collision. At the same time, the protective cover 706 provides closed protection for the main sensing component 7 in the barrel disc 701, effectively improving the protection effect of the main sensing component 7.

[0045] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
