[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0030] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; of course, they can also refer to a mechanical connection or an electrical connection; furthermore, they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] Example 1, as Figure 1-9 As shown, the present invention provides a multi-stage lifting and maintenance mobile platform, including a mounting base 1, several moving mechanisms rotatably mounted on the mounting base 1 and moving along tracks, a track-changing mechanism located at the bottom of the mounting base 1, a first lifting mechanism mounted on the mounting base 1, a unfolding mechanism slidably mounted on the first lifting mechanism, a second lifting mechanism mounted on the first lifting mechanism and passing through the unfolding mechanism, and an extension mechanism rotatably mounted on both sides of the first lifting mechanism. The lifting mechanism and the unfolding mechanism are provided with protective mechanisms.

[0033] The present invention enables maintenance personnel to maintain and repair the tunnel at different heights by using a first lifting mechanism, a second lifting mechanism, and an extension mechanism in coordination.

[0034] The protective mechanism of this invention can protect maintenance personnel on the deployment mechanism during use, thereby improving the safety of maintenance personnel.

[0035] This invention increases the usable area of ​​the first lifting mechanism by activating the deployment mechanism, making it easier for maintenance personnel to maintain and care for the tunnel walls.

[0036] The rail-changing mechanism of the present invention can not only perform rail-changing operations on the mounting base 1, but also support the mounting base 1, thereby improving the stability of the first lifting mechanism, the second lifting mechanism and the extension mechanism.

[0037] In use, the mounting base 1 is pushed, and the mounting base 1 moves on the track via a moving mechanism. When it moves to the designated position, the track-changing mechanism is activated to fix the mounting base 1. At this time, maintenance personnel can open the unfolding mechanism and the extension mechanism. Maintenance personnel can stand on the unfolding mechanism and the extension mechanism to maintain and service the tunnel. When maintenance personnel need to raise the height of the unfolding mechanism, the first lifting mechanism is activated, which raises the unfolding mechanism to increase its height. If it is necessary to further increase the height of the maintenance personnel, the maintenance personnel only need to enter the second lifting mechanism and then activate the second lifting mechanism, which raises the maintenance personnel to facilitate maintenance and service of the tunnel. At the same time, the track-changing mechanism is activated, which can also move the mounting base 1 laterally to an adjacent track to realize the track-changing operation of the mounting base 1, so as to facilitate maintenance and service of the tunnel.

[0038] Example 2, as Figure 1-9 As shown, the present invention provides a multi-stage lifting and maintenance mobile platform, including a mounting base 1, several moving mechanisms rotatably mounted on the mounting base 1 and moving along tracks, a track-changing mechanism located at the bottom of the mounting base 1, a first lifting mechanism mounted on the mounting base 1, a unfolding mechanism slidably mounted on the first lifting mechanism, a second lifting mechanism mounted on the first lifting mechanism and passing through the unfolding mechanism, and an extension mechanism rotatably mounted on both sides of the first lifting mechanism.

[0040] In this embodiment 2, the rectangular column 2 and the support column 3 work together to guide the movement direction of the installation platform 5, and at the same time protect the first hydraulic cylinder 4 and improve the service life of the first hydraulic cylinder 4.

[0041] When using this invention, maintenance personnel can enter the deployment mechanism via the telescopic climbing ladder A7, activate the first hydraulic cylinder 4, and the first hydraulic cylinder 4 drives the installation platform 5 to rise. The installation platform 5 drives the deployment mechanism to move synchronously, thereby achieving height adjustment of the deployment mechanism, which facilitates maintenance personnel to maintain and repair the tunnel. In this invention, the reinforcing rod 6 can increase the stability between the rectangular columns 2.

[0042] Example 3, as Figure 1-9As shown, the present invention provides a multi-stage lifting and maintenance mobile platform, including a mounting base 1, several moving mechanisms rotatably mounted on the mounting base 1 and moving along tracks, a track-changing mechanism located at the bottom of the mounting base 1, a first lifting mechanism mounted on the mounting base 1, a unfolding mechanism slidably mounted on the first lifting mechanism, a second lifting mechanism mounted on the first lifting mechanism and passing through the unfolding mechanism, and an extension mechanism rotatably mounted on both sides of the first lifting mechanism. The lifting mechanism and the unfolding mechanism are provided with protective mechanisms.

[0043] The first lifting mechanism includes several rectangular columns 2 mounted on the mounting base 1, a support column 3 slidably mounted inside the rectangular columns 2, a first hydraulic cylinder 4 mounted inside the rectangular columns 2 and connected to the top of the support column 3, and a mounting platform 5 mounted on the support column 3 and connected to the unfolding mechanism; a reinforcing rod 6 is provided between two adjacent rectangular columns 2, an extension mechanism is rotatably mounted between two rectangular columns 2, and a telescopic climbing ladder A7 is provided on the mounting platform 5.

[0044] The deployment mechanism includes two deployment platforms 8 mirror-mounted on the installation platform 5, and several second hydraulic rods 9 mounted on the installation platform 5 and connected to the two deployment platforms 8 respectively; the protective mechanism is mounted on the deployment platform 8.

[0045] In this embodiment 3, the second hydraulic rod 9 is activated, which pushes the two unfolding platforms 8 to slide on the mounting platform 5, causing the unfolding platforms 8 to unfold to both sides, thereby expanding the operating space. At the same time, after the unfolding platforms 8 are unfolded, the protective mechanism set on the unfolding platforms 8 is put into place simultaneously, forming a safety protection for maintenance personnel to ensure their safety.

[0046] Example 4, as Figure 1-9 As shown, the present invention provides a multi-stage lifting and maintenance mobile platform, including a mounting base 1, several moving mechanisms rotatably mounted on the mounting base 1 and moving along tracks, a track-changing mechanism located at the bottom of the mounting base 1, a first lifting mechanism mounted on the mounting base 1, a unfolding mechanism slidably mounted on the first lifting mechanism, a second lifting mechanism mounted on the first lifting mechanism and passing through the unfolding mechanism, and an extension mechanism rotatably mounted on both sides of the first lifting mechanism. The lifting mechanism and the unfolding mechanism are provided with protective mechanisms.

[0047] The first lifting mechanism includes several rectangular columns 2 mounted on the mounting base 1, a support column 3 slidably mounted inside the rectangular columns 2, a first hydraulic cylinder 4 mounted inside the rectangular columns 2 and connected to the top of the support column 3, and a mounting platform 5 mounted on the support column 3 and connected to the unfolding mechanism; a reinforcing rod 6 is provided between two adjacent rectangular columns 2, an extension mechanism is rotatably mounted between two rectangular columns 2, and a telescopic climbing ladder A7 is provided on the mounting platform 5.

[0048] The deployment mechanism includes two deployment platforms 8 mirror-mounted on the installation platform 5, and several second hydraulic rods 9 mounted on the installation platform 5 and connected to the two deployment platforms 8 respectively; the protective mechanism is mounted on the deployment platform 8.

[0049] The unfolding platform 8 has a protective clearance groove 10 at each end. The protective mechanism includes a protective column A11 installed on the installation platform 5 and passing through the protective clearance groove 10, a protective sleeve 12 installed on the protective column A11, a protective column B13 installed on the unfolding platform 8, and a protective column 14 installed on the protective column B13.

[0050] In this embodiment 4, when the second hydraulic rod 9 pushes the deployment platform 8 to slide horizontally to both sides, the protective column B13 on the deployment platform 8 moves synchronously with the deployment platform 8. At the same time, the protective column 14 moves synchronously with the protective column B13, and drives the protective column 14 to move synchronously within the protective sleeve 12, thereby protecting the maintenance personnel on the deployment platform 8. In addition, the protective column 14 has an entry port corresponding to the telescopic climbing ladder A7 to facilitate maintenance personnel entering the deployment platform 8. Example

[0051] like Figure 1-9 As shown, the present invention provides a multi-stage lifting and maintenance mobile platform, including a mounting base 1, several moving mechanisms rotatably mounted on the mounting base 1 and moving along tracks, a track-changing mechanism located at the bottom of the mounting base 1, a first lifting mechanism mounted on the mounting base 1, a unfolding mechanism slidably mounted on the first lifting mechanism, a second lifting mechanism mounted on the first lifting mechanism and passing through the unfolding mechanism, and an extension mechanism rotatably mounted on both sides of the first lifting mechanism. The lifting mechanism and the unfolding mechanism are provided with protective mechanisms.

[0052] The first lifting mechanism includes several rectangular columns 2 mounted on the mounting base 1, a support column 3 slidably mounted inside the rectangular columns 2, a first hydraulic cylinder 4 mounted inside the rectangular columns 2 and connected to the top of the support column 3, and a mounting platform 5 mounted on the support column 3 and connected to the unfolding mechanism; a reinforcing rod 6 is provided between two adjacent rectangular columns 2, an extension mechanism is rotatably mounted between two rectangular columns 2, and a telescopic climbing ladder A7 is provided on the mounting platform 5.

[0053] The second lifting mechanism includes several guide columns 15 mounted on the installation platform 5, guide rods 16 slidably mounted in the guide columns 15, a fourth hydraulic cylinder 17 mounted in the guide columns 15 and connected to the guide rods 16, and a lifting platform 18 mounted on the guide rods 16; the lifting platform 18 is equipped with a guardrail 19 and a telescopic climbing ladder B20. The installation platform 5 is provided with several guide grooves 21, and guide wheels 22 connected to the bottom of the unfolding platform 8 are provided in the guide grooves 21.

[0054] In this embodiment 5, a lifting clearance groove is provided in the middle of the two unfolding platforms 8. The guide column 15 is fixedly installed on the installation platform 5 and passes through the lifting clearance groove. In this invention, the guide rod 16 and the guide column 15 cooperate to guide the movement direction of the lifting platform 18, thereby improving the stability of the lifting platform 18. When this invention is used, the fourth hydraulic cylinder 17 is activated, and the fourth hydraulic cylinder 17 drives the guide rod 16 to lift and lower. The guide rod 16 drives the lifting platform 18 to rise, thereby facilitating the maintenance personnel to adjust the height of the lifting platform 18 and facilitating the maintenance personnel to maintain the tunnel.

[0055] The present invention facilitates the unfolding of the unfolding platform 8 by using the guide groove 21 and the guide wheel 22 in cooperation, thereby reducing the friction of the unfolding platform 8 during the sliding process.

[0056] Example 6, as Figure 1-9 As shown, the present invention provides a multi-stage lifting and maintenance mobile platform, including a mounting base 1, several moving mechanisms rotatably mounted on the mounting base 1 and moving along tracks, a track-changing mechanism located at the bottom of the mounting base 1, a first lifting mechanism mounted on the mounting base 1, a unfolding mechanism slidably mounted on the first lifting mechanism, a second lifting mechanism mounted on the first lifting mechanism and passing through the unfolding mechanism, and an extension mechanism rotatably mounted on both sides of the first lifting mechanism. The lifting mechanism and the unfolding mechanism are provided with protective mechanisms.

[0057] The mounting base 1 is provided with a detachable transfer track 23. The track changing mechanism includes a lifting support arm 24 rotatably mounted on the mounting base 1, a lifting hydraulic cylinder 25 mounted on the lifting support arm 24, and a number of rolling mechanisms located at the bottom of the mounting base 1 and adapted to the transfer track 23.

[0058] In this embodiment 6, the lifting support arm 24 is rotatably mounted on the mounting base 1, which facilitates the storage of the lifting support arm 24. At the same time, when in use, the lifting hydraulic cylinder 25 is activated, which pushes the lifting support arm 24 to rise. The lifting support arm 24 drives the mounting base 1 to move synchronously, thereby fixing the mounting base 1 and preventing the moving mechanism from sliding on the track, thus improving the stability of the mounting base 1.

[0059] Simultaneously, when it is necessary to move the mounting base 1 laterally to an adjacent track, the moving mechanism is activated, which drives the mounting base 1 to rise. At this time, the maintenance personnel place the transfer track 23 between two adjacent tracks, directly below the rolling mechanism. Then, the moving mechanism is activated again, so that the rolling mechanism is on the transfer track and the moving mechanism is separated from the track. The maintenance personnel push the mounting base 1 to move it to the adjacent track, and then activate the moving mechanism to move it to the adjacent track, thereby realizing the track changing operation of the mounting base 1.

[0060] Example 7, as Figure 1-9 As shown, the present invention provides a multi-stage lifting and maintenance mobile platform, including a mounting base 1, several moving mechanisms rotatably mounted on the mounting base 1 and moving along tracks, a track-changing mechanism located at the bottom of the mounting base 1, a first lifting mechanism mounted on the mounting base 1, a unfolding mechanism slidably mounted on the first lifting mechanism, a second lifting mechanism mounted on the first lifting mechanism and passing through the unfolding mechanism, and an extension mechanism rotatably mounted on both sides of the first lifting mechanism. The lifting mechanism and the unfolding mechanism are provided with protective mechanisms.

[0061] The mounting base 1 is provided with a detachable transfer track 23. The track changing mechanism includes a lifting support arm 24 rotatably mounted on the mounting base 1, a lifting hydraulic cylinder 25 mounted on the lifting support arm 24, and a number of rolling mechanisms located at the bottom of the mounting base 1 and adapted to the transfer track 23.

[0062] The rolling mechanism includes a slide rail support 26 mounted on the mounting base 1, a mounting column 27 slidably mounted in the slide rail support 26, a third hydraulic cylinder 28 mounted in the slide rail support 26 and connected to the mounting column 27, and a slide rail roller 29 mounted on the mounting column 27 and adapted to the transfer track 23.

[0063] In this embodiment 7, when in use, the third hydraulic cylinder 28 is activated, and the third hydraulic cylinder 28 pushes the mounting column 27 to slide within the slide rail support column 26. During the sliding process, the slide rail support column 26 drives the slide rail roller 29 to move synchronously, thereby adjusting the height of the slide rail roller 29, which facilitates the placement of the slide rail roller 29 on the transfer track 23 and facilitates the track replacement operation of the mounting base 1.

[0064] Example 8, as Figure 1-9 As shown, the present invention provides a multi-stage lifting and maintenance mobile platform, including a mounting base 1, several moving mechanisms rotatably mounted on the mounting base 1 and moving along tracks, a track-changing mechanism located at the bottom of the mounting base 1, a first lifting mechanism mounted on the mounting base 1, a unfolding mechanism slidably mounted on the first lifting mechanism, a second lifting mechanism mounted on the first lifting mechanism and passing through the unfolding mechanism, and an extension mechanism rotatably mounted on both sides of the first lifting mechanism. The lifting mechanism and the unfolding mechanism are provided with protective mechanisms.

[0065] The unfolding mechanism includes a rotating seat 30 mirror-mounted on the first lifting mechanism, an extension plate 31 rotatably mounted between the two rotating seats 30, and a fifth hydraulic cylinder 32 with one end hinged to the first lifting mechanism and the other end hinged to the extension plate 31.

[0066] In this embodiment 8, during use, the fifth hydraulic cylinder 32 is activated, which pushes the extension plate 31 to rotate between the two rotating seats 30 until the extension plate 31 is parallel to the mounting base 1, thereby unfolding the extension plate 31. At this time, maintenance personnel can enter the extension plate 31 through the telescopic climbing ladder A7 to maintain and repair the tunnel. At the same time, when the extension plate 31 is not needed, the fifth hydraulic cylinder 32 is activated, which can store the extension plate 31, reducing the space occupancy rate of the extension plate 31.

[0067] Example 9, as Figure 1-9 As shown, the present invention provides a multi-stage lifting and maintenance mobile platform, including a mounting base 1, several moving mechanisms rotatably mounted on the mounting base 1 and moving along tracks, a track-changing mechanism located at the bottom of the mounting base 1, a first lifting mechanism mounted on the mounting base 1, a unfolding mechanism slidably mounted on the first lifting mechanism, a second lifting mechanism mounted on the first lifting mechanism and passing through the unfolding mechanism, and an extension mechanism rotatably mounted on both sides of the first lifting mechanism. The lifting mechanism and the unfolding mechanism are provided with protective mechanisms.

[0068] The moving mechanism includes a mounting column 33 mounted on the mounting base 1, a movable mounting rod 34 slidably mounted in the mounting column 33, a sixth hydraulic cylinder 35 mounted on the mounting base 1 and connected to the movable mounting rod 34, and a moving wheel 36 rotatably mounted on the movable mounting rod 34.

[0069] In this embodiment 9, the cooperation between the mounting column 33 and the movable mounting rod 34 facilitates the guidance of the movement direction of the movable wheel 36, enabling the movable wheel 36 to engage with the track. When using this invention, the sixth hydraulic cylinder 35 is activated, causing the movable mounting rod 34 to slide within the mounting column 33. The movable mounting rod 34 then drives the movable wheel 36 to move synchronously, allowing the movable wheel 36 to engage with the track.

[0070] A method for using a multi-stage lifting and maintenance mobile platform includes the following steps: S1. Push the mounting base 1 to move it to the designated position. S2. Extend the lifting arm 24 and activate the third hydraulic cylinder 28. The third hydraulic cylinder 28 lifts the mounting base 1, thereby fixing the mounting base 1. S3. When the height required by the maintenance personnel is lower than the lowest position of the first lifting mechanism, the fifth hydraulic cylinder 32 is activated. The fifth hydraulic cylinder 32 pushes the extension plate 31 to rotate, so that the extension plate 31 is parallel to the installation platform 5. At this time, the maintenance personnel can enter the extension plate 31 through the telescopic climbing ladder A7 to maintain and repair the tunnel wall. S4. When it is necessary to further increase the height of maintenance personnel, the second hydraulic rod 9 is activated. The second hydraulic rod 9 pushes the two deployment platforms 8 to move, so that the two deployment platforms 8 are deployed on the installation platform 5, thereby expanding the usable space of the deployment platforms 8. S5. Maintenance personnel enter the deployment platform 8 via the telescopic climbing ladder A7 to perform maintenance work; at the same time, by activating the first hydraulic cylinder 4, the first hydraulic cylinder 4 pushes the installation platform 5 to rise, thereby adjusting the height of the deployment platform 8; S6. When the height of the unfolding platform 8 is insufficient, maintenance personnel enter the lifting platform 18 through the telescopic climbing ladder B20. Then, the fourth hydraulic cylinder 17 is activated, and the fourth hydraulic cylinder 17 pushes the lifting platform 18 to rise, thereby adjusting the height of the lifting platform 18. S7. When it is necessary to perform track replacement work on the mounting base 1, the transfer track 23 is placed under the slide rail roller 29, and the maintenance personnel push the mounting base 1 to slide along the transfer track 23 to achieve the track replacement work.

[0071] The first hydraulic rod, second hydraulic rod 9, third hydraulic rod, fourth hydraulic rod, fifth hydraulic rod, sixth hydraulic rod and lifting hydraulic cylinder 25 used in this invention are existing technologies and can be purchased and used directly on the market.
