Description

Technical Field

[0001] This application belongs to the technical field of aerial work platforms, specifically relating to an active vibration reduction system for an aerial work platform and an aerial work platform. Background Technology

[0002] Aerial work platforms are essential engineering vehicles serving various fields such as industrial construction, municipal construction, equipment installation, and maintenance. They provide efficient and mobile working platforms for high-altitude operations. However, in actual high-altitude operations, these platforms often face various vibration disturbances, including frequent wind disturbances, uneven ground, or significant vibrations generated by the equipment's own operation. These factors result in large vibration amplitudes, affecting not only operational accuracy but also directly reducing the safety and comfort of high-altitude workers.

[0003] Currently, many aerial work platforms still rely primarily on passive vibration damping components such as springs and hydraulic cylinders to suppress vibration. While these traditional vibration damping methods are simple in structure and low in cost, their vibration damping effect is limited, and they cannot actively adjust or respond in real time according to vibration conditions.

The mounting components include a first mounting seat and a second mounting seat that are spaced apart, and a mounting opening is formed between the first mounting seat and the second mounting seat. Both the first mounting seat and the second mounting seat include a sleeve section and a connecting section that are connected to each other. The sleeve section of the first mounting seat forms a second hinge hole, and the sleeve section of the second mounting seat forms a third hinge hole. The working platform forms a mounting groove, and the connecting section is snapped into the mounting groove.

[0009] In the embodiments of this application, the electronically controlled vibration damper is one of an electromagnetic linear actuator, an electro-hydraulic vibration damper, or an inflatable vibration damper.

[0010] In this embodiment, the electronically controlled vibration damper is configured as an electromagnetic linear actuator. The electromagnetic linear actuator includes a magnetic housing, a coil, and a moving iron core. The magnetic housing has a fixing part at one end near the mounting platform. The coil is located inside the magnetic housing. One end of the moving iron core passes through the coil, and the other end of the moving iron core extends out of the magnetic housing and is provided with a telescopic vibration damping part.

[0011] In this embodiment, the magnetic housing includes a magnetic outer shell, a non-magnetic guide sleeve, and an end plate. The magnetic outer shell is disposed on the fixed part and has an electrical connector. The non-magnetic guide sleeve is disposed inside the magnetic outer shell. The end plate covers the magnetic outer shell. The coil is disposed inside the non-magnetic guide sleeve. The end of the moving iron core away from the fixed part extends out of the end plate.

[0012] In this embodiment, the moving iron core has a stepped surface, and the electromagnetic linear actuator also includes a reset elastic element. The reset elastic element is sleeved outside the moving iron core, and its two ends are respectively connected to the stepped surface and the end plate.

[0013] In this embodiment, a sealing ring is provided between the end plate and the magnetically conductive outer shell.

[0014] In this embodiment of the application, the electromagnetic linear actuator further includes a first guide pole shoe and a second guide pole shoe, which are respectively disposed at opposite ends of the non-magnetic guide sleeve.

The controller is connected to both the inertial sensor and the electrically controlled vibration damper, allowing the detection data from the inertial sensor to be transmitted to the controller. The controller can control the electrically controlled vibration damper based on the detection data from the inertial sensor, causing the damper to extend and retract to move the working platform. This actively compensates for changes in the working platform's attitude. When the inertial sensor detects an upward acceleration in the working platform, the electrically controlled vibration damper retracts to move the working platform downward, reducing the vibration amplitude of the working platform. This achieves active adjustment and real-time response based on vibration conditions.

[0021] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0022] The descriptions of directions such as "up", "down", "front", "back", "left", and "right" in this application are as follows: Figure 1 The directions shown are for reference only and are used to interpret the location. Figure 1 The relative positional relationship between the components in the shown posture is such that if the specific posture changes, the directional indication will also change accordingly.

[0023] The active vibration reduction system for the work platform and the aerial work platform of this application are described below with reference to the accompanying drawings.

[0024] like Figures 1 to 4 As shown, this application provides an active vibration damping system for a work platform, which includes a platform assembly 10 and an active vibration damping device. The platform assembly 10 includes a mounting platform 11 and a working platform 12 arranged sequentially from bottom to top. The mounting platform 11 is used to mount the equipment boom, and an inertial sensor 121 is installed on the working platform 12. The active vibration damping device includes a controller 20 and an electronically controlled vibration damper 30. The electronically controlled vibration damper 30 is located between the mounting platform 11 and the working platform 12, and the fixing part 31 of the electronically controlled vibration damper 30 is provided on the mounting platform 11, and the telescopic vibration damping part 32 is connected to the working platform 12. The controller 20 is connected to the inertial sensor 121 and the electronically controlled vibration damper 30 by signals.

[0025] The mounting platform 11 and the working platform 12 are arranged alternately from bottom to top. The mounting platform 11 is used to mount the equipment boom, and the equipment boom can drive the mounting platform 11 to rise and fall. An inertial sensor 121 is installed on the working platform 12. The working platform 12 is used for high-altitude workers to stand and work. The inertial sensor 121 is used to detect the vibration data of the working platform 12. An electronically controlled vibration damper 30 is provided between the mounting platform 11 and the working platform 12. The fixed part 31 of the electronically controlled vibration damper 30 is provided on the mounting platform 11, and the telescopic vibration damping part 32 of the electronically controlled vibration damper 30 is connected to the working platform 12. The telescopic vibration damping part 32 can extend and retract to drive the working platform 12 to move. The controller 20 is connected to the inertial sensor 121 and the electronically controlled vibration damper 30, respectively, so that the detection data of the inertial sensor 121 can be transmitted to the controller 20. The controller 20 can control the electronically controlled vibration damper 30 according to the detection data of the inertial sensor 121, so that the electronically controlled vibration damper 30 extends and retracts to drive the work platform 12 to move, and actively compensate for the attitude changes of the work platform 12. When the inertial sensor 121 detects that the work platform 12 has an upward acceleration, the electronically controlled vibration damper 30 retracts to drive the work platform 12 to move downward, thereby reducing the vibration amplitude of the work platform 12, thus realizing active adjustment and real-time response according to the vibration situation.

[0026] The vibration data may include linear acceleration and angular velocity in the up-down, left-right, and forward-backward directions. The inertial sensor 121 may be an IMU (Inertial Measurement Unit) sensor, including an accelerometer, gyroscope, and magnetometer.

[0027] In the embodiments of this application, please refer to Figure 3 The number of electronically controlled vibration dampers 30 is at least two, and the at least two electronically controlled vibration dampers 30 are arranged at intervals. The telescopic vibration damping parts 32 of the at least two electronically controlled vibration dampers 30 are all movably hinged to the working platform 12 through the hinge shaft 127.

[0028] At least two electronically controlled vibration dampers 30 are spaced apart on the mounting platform 11, and the electronically controlled vibration dampers 30 are movably hinged to the working platform 12 via a hinge shaft 127, so that the working platform 12 can make adaptive small-angle swings under the action of the electronically controlled vibration dampers 30.

[0029] like Figure 3As shown, there are four electrically controlled vibration dampers 30: a first electrically controlled vibration damper 30a, a second electrically controlled vibration damper 30b, a third electrically controlled vibration damper 30c, and a fourth electrically controlled vibration damper 30d. When the first electrically controlled vibration damper 30a and the second electrically controlled vibration damper 30b are in one group, and the third electrically controlled vibration damper 30c and the fourth electrically controlled vibration damper 30d are in another group, the work platform 12 can swing back and forth slightly by controlling the extension and retraction of the first electrically controlled vibration damper 30a and the second electrically controlled vibration damper 30b. When the first electrically controlled vibration damper 30a and the third electrically controlled vibration damper 30c are in one group, and the second electrically controlled vibration damper 30b and the fourth electrically controlled vibration damper 30d are in another group, the work platform 12 can swing left and right slightly by controlling the extension and retraction of the first electrically controlled vibration damper 30a and the third electrically controlled vibration damper 30c.

[0030] In the embodiments of this application, please refer to Figure 3 and Figure 4 The telescopic damping part 32 has a first hinge hole 321, and the bottom of the working platform 12 has a downward-facing mounting port 122. The mounting port 122 has a second hinge hole 1241 and a third hinge hole on opposite sides. The telescopic damping part 32 extends into the mounting port 122 so that the first hinge hole 321, the second hinge hole 1241 and the third hinge hole are connected. The hinge shaft 127 passes through the first hinge hole 321, the second hinge hole 1241 and the third hinge hole.

[0031] The mounting opening 122 has a second hinge hole 1241 and a third hinge hole on its left and right sides, respectively. The telescopic damping part 32 has a first hinge hole 321, and the telescopic damping part 32 extends into the mounting opening 122, so that the first hinge hole 321, the second hinge hole 1241, and the third hinge hole are connected. The hinge shaft 127 passes through the second hinge hole 1241, the first hinge hole 321, and the third hinge hole in sequence, so that the telescopic damping part 32 is movably hinged to the working platform 12 via the hinge shaft 127.

[0032] In the embodiments of this application, please refer to Figure 3 and Figure 4 The bottom of the working platform 12 is provided with at least two mounting components 123, and the at least two mounting components 123 are respectively arranged in a one-to-one correspondence with at least two electronically controlled vibration dampers 30. The mounting component 123 includes a first mounting seat 124 and a second mounting seat 125 arranged at intervals. A mounting opening 122 is formed between the first mounting seat 124 and the second mounting seat 125. The first mounting seat 124 and the second mounting seat 125 each include a connected sleeve section 1242 and a connecting section 1243. The sleeve section 1242 of the first mounting seat 124 forms a second hinge hole 1241, and the sleeve section 1242 of the second mounting seat 125 forms a third hinge hole. The working platform 12 forms a mounting groove 126, and the connecting section 1243 is snapped into the mounting groove 126.

[0033] At least two mounting components 123 are provided in equal numbers to at least two electronically controlled vibration dampers 30, and are arranged in a one-to-one correspondence. Each mounting component 123 includes a first mounting base 124 and a second mounting base 125 spaced apart in a left-right direction, forming a mounting opening 122. The fitting segments 1242 of the first mounting base 124 and the second mounting base 125 respectively form a second hinge hole 1241 and a third hinge hole. A mounting groove 126 is formed at the bottom of the work platform 12, and a connecting segment 1243 is fitted into the mounting groove 126. By providing the mounting groove 126 and the connecting segment 1243 in cooperation, the contact area between the first mounting base 124 and the second mounting base 125 and the work platform 12 is increased, thereby improving connection stability and reliability.

[0034] It is understandable that the cross-sectional area of ​​the connecting section 1243 is larger than that of the fitting section 1242, resulting in a larger contact area between the connecting section 1243 and the working platform 12.

[0035] In this embodiment, the electronically controlled vibration damper 30 is one of an electromagnetic linear actuator 40, an electro-hydraulic vibration damper, or an inflatable vibration damper.

[0036] The electromagnetic linear actuator 40 converts electromagnetic force into control force by receiving instructions from the controller 20, so as to suppress or eliminate structural vibration.

[0037] Electro-hydraulic shock absorbers eliminate or reduce impact and vibration by utilizing the flow of liquid in a closed pipe to convert kinetic energy into heat energy. When the working platform 12 is subjected to impact or vibration, the piston inside the electro-hydraulic shock absorber moves, causing the liquid to flow in the sealed pipe, generating a damping effect, thereby converting kinetic energy into heat energy and reducing the vibration of the working platform 12.

[0038] The pneumatic shock absorber is a new type of shock absorber with a single-tube structure. It uses high-pressure nitrogen gas and oil to achieve the damping function. The core structure of the pneumatic shock absorber includes a nitrogen chamber and an oil chamber separated by a floating piston. The floating piston is equipped with a valve that changes its channel according to speed. The damping force generated by the hydraulic pressure difference of the oil gas attenuates the vibration, and the expansion and compression of nitrogen gas compensates for the volume change.

[0039] In the embodiments of this application, please refer to Figure 2 The electronically controlled vibration damper 30 is configured as an electromagnetic linear actuator 40. The electromagnetic linear actuator 40 includes a magnetic housing 41, a coil 42, and a moving iron core 43. The magnetic housing 41 has a fixing part 31 at one end near the mounting platform 11. The coil 42 is located inside the magnetic housing 41. One end of the moving iron core 43 passes through the coil 42, and the other end of the moving iron core 43 extends out of the magnetic housing 41 and is provided with a telescopic vibration damping part 32.

[0040] The electrically controlled vibration damper 30 is configured as an electromagnetic linear actuator 40, which has the advantage of fast response speed, reaching the millisecond level. A fixing part 31 is provided at the lower end of the magnetically conductive housing 41, which is connected to the mounting platform 11 to ensure stable mounting of the electromagnetic linear actuator 40 on the platform 11. The magnetically conductive housing 41 is made of magnetically conductive material and is used to close the magnetic flux. A coil 42 is located inside the magnetically conductive housing 41. When energized, the coil 42 generates a magnetic field, which is adjusted by the current. The lower end of the moving iron core 43 passes through the coil 42, and the upper end of the moving iron core 43 extends out of the magnetically conductive housing 41 and is equipped with a telescopic vibration damping part 32. The magnetic field generates an electromagnetic attraction on the moving iron core 43, allowing it to move vertically. The moving iron core 43 drives the telescopic vibration damping part 32 to move vertically, thereby moving the working platform 12.

[0041] In the embodiments of this application, please refer to Figure 2 The magnetic housing 41 includes a magnetic outer shell 411, a non-magnetic guide sleeve 412, and an end plate 413. The magnetic outer shell 411 is disposed on the fixing part 31 and is provided with an electrical connector 4111. The non-magnetic guide sleeve 412 is disposed inside the magnetic outer shell 411. The end plate 413 is disposed on the magnetic outer shell 411. The coil 42 is disposed inside the non-magnetic guide sleeve 412. The end of the moving iron core 43 away from the fixing part 31 extends out of the end plate 413.

[0042] A magnetically conductive outer shell 411 is mounted on the fixed part 31. The magnetically conductive outer shell 411 has an energizing structure for connecting a power source to supply power to the coil 42. A non-magnetic guiding sleeve 412 is disposed inside the magnetically conductive outer shell 411, and the coil 42 is housed within the non-magnetic guiding sleeve 412. The lower end of the moving iron core 43 passes through the coil 42. The non-magnetic guiding sleeve 412 provides guidance, allowing the moving iron core 43 to move stably and reliably in the vertical direction. Furthermore, the non-magnetic guiding sleeve 412 prevents the moving iron core 43 from being attracted to the magnetically conductive outer shell 411, improving the movement efficiency of the moving iron core 43. The non-magnetic guiding sleeve 412 is made of a non-magnetic material, such as stainless steel, copper, or glass. A lubricant can be placed inside the non-magnetic guiding sleeve 412 to lubricate the vertical movement of the moving iron core 43.

[0043] End plate 413 is placed on magnetic housing 411, and the upper end of moving iron core 43 extends out of end plate 413. End plate 413 can seal and guide the up and down movement of moving iron core 43.

[0044] In the embodiments of this application, please refer to Figure 2 The moving iron core 43 has a stepped surface 431. The electromagnetic linear actuator 40 also includes a reset elastic element 44, which is sleeved on the outside of the moving iron core 43, and the two ends of the reset elastic element 44 are respectively connected to the stepped surface 431 and the end plate 413.

[0045] The upper end of the reset elastic element 44 is connected to the end plate 413, and the lower end of the reset elastic element 44 is connected to the stepped surface 431. The reset elastic element 44 provides the force to reset the moving iron core 43 after the coil 42 is de-energized. The preload of the reset elastic element 44 determines the minimum starting current and reset speed of the electromagnetic linear actuator 40. The reset elastic element 44 can be a spring, an elastic sleeve, or other elastic element.

[0046] Based on this, please refer to Figure 2 A sealing ring 45 is provided between the end plate 413 and the magnetic housing 411. The sealing ring 45 can prevent external dust and impurities from entering the interior of the electromagnetic linear actuator 40, and at the same time prevent the lubricant inside the electromagnetic linear actuator 40 from leaking, thereby improving the reliability and service life of the electromagnetic linear actuator 40.

[0047] Based on this, please refer to Figure 2 The electromagnetic linear actuator 40 also includes a first guide pole shoe 46 and a second guide pole shoe 47, which are respectively located at opposite ends of the non-magnetic guide sleeve 412.

[0048] By setting a first guide pole piece 46 and a second guide pole piece 47 at opposite ends of the non-magnetic guide sleeve 412, the magnetic field is optimized and its distribution is improved, so that the electromagnetic direction is along the vertical direction. The first guide pole piece 46 and the second guide pole piece 47 are made of a high magnetic permeability material.

[0049] In this embodiment, the fixing part 31 and the mounting platform 11 are detachably connected by fasteners, facilitating replacement of the electrically controlled vibration damper 30 after wear and improving the flexibility of use of the electrically controlled vibration damper 30. The fasteners can be bolts, which have the advantages of being readily available and easy to install. In other embodiments, the fasteners can also be rivets, clips, or other structures that enable a detachable connection.

[0050] In the embodiments of this application, please refer to Figure 1 and Figure 3 The active vibration damping system of the work platform also includes a side guard plate 50, which is connected to the mounting platform 11 and extends toward the work platform 12. The side guard plate 50 extends out of the electrically controlled vibration damper 30 and the side guard plate 50 and the mounting platform 11 enclose to form a mounting cavity 51. The work platform 12 and the electrically controlled vibration damper 30 are both located in the mounting cavity 51.

[0051] Side guard plates 50 are disposed around the mounting platform 11. The side guard plates 50 are connected to the mounting platform 11 for installation and fixation. The side guard plates 50 extend towards the working platform 12 and protrude beyond the electrically controlled vibration damper 30. The side guard plates 50 and the mounting platform 11 enclose a mounting cavity 51, which accommodates the working platform 12 and the electrically controlled vibration damper 30. By providing the side guard plates 50, large-angle rotation or displacement of the working platform 12 due to failure of the electrically controlled vibration damper 30 is prevented, thus improving safety and reliability.
