DETAILED DESCRIPTION

[0057] The present invention will be further described below with reference to the accompanying drawings.

[0058] Please also refer to Figure 1-Figure 5 The embodiment of the present invention provides a lifting frame 100, comprising a base 1, a first motor 2, a bearing plate 5, a telescopic connecting rod 4, a maintenance platform 14 and a second motor 6. The base 1 can be moved in a first direction (such as Figure 1 The base 1 is provided with a first motor 2. The inner rotation of the supporting plate 5 is provided with a motor 2 along the second direction (as shown in the X direction). Figure 2 The driving wheel 9 and the driven wheel 11 are spaced apart in the Y direction, and the rotation axis of the driving wheel 9 and the driven wheel 11 extends in the third direction (as shown in FIG. Figure 2 The base 1 and the support plate 5 are connected to each other (as shown in the Z direction), and the driving wheel 9 and the driven wheel 11 are provided with a synchronous belt 10, and the synchronous belt 10 is provided with a first connecting rod 12 protruding from the top surface of the support plate 5, wherein the first direction, the second direction and the third direction are perpendicular to each other. The telescopic link 4 is connected between the base 1 and the bottom surface of the support plate 5, and the telescopic link 4 is connected to the first motor 2, and can drive the support plate 5 to rise and fall under the drive of the first motor 2. The maintenance platform 14 is slidably set on the top surface of the support plate 5, and the maintenance platform 14 is connected to the first connecting rod 12. The second motor 6 is connected to the driving wheel 9, and the second motor 6 can drive the driving wheel 9 to rotate and drive the first connecting rod 12 to move along the second direction through the synchronous belt 10, so as to drive the maintenance platform 14 to move along the second direction.

[0059] For example, when the lifting frame 100 is used for railway maintenance, the first direction is substantially the extending direction of the railway, the second direction is substantially the horizontal direction and perpendicular to the extending direction of the railway, and the third direction is substantially the vertical direction.

[0060] The working principle of this embodiment is that when a line on a railway fails, railway maintenance personnel conduct maintenance on it. Since the wires are relatively high, maintenance personnel standing on the maintenance platform 14 start the first motor 2 to drive the telescopic connecting rod 4 to drive the load-bearing plate 5 to rise, thereby driving the maintenance platform 14 to rise, so as to inspect the wires approximately directly above the lifting frame 100. The second motor 6 is then started to rotate, driving the driving wheel 9 to rotate, thereby driving the first connecting rod 12 to move in the second direction via the synchronous belt 10, thereby driving the maintenance platform 14 to slide in the second direction. This allows maintenance personnel to inspect more wires without moving the base 1, thereby improving the maintenance range and efficiency of the lifting frame 100 and further ensuring the safety of maintenance personnel.

[0061] In addition, a first ball 13 is provided on the surface of the first connecting rod 12 , and the maintenance platform 14 is provided with a moving groove 18 for accommodating the first connecting rod 12 . The first ball 13 abuts against the side wall of the moving groove 18 .

[0062] Please also refer to Figure 3 、 Figure 4 and Figure 6 In some embodiments, the lifting frame 100 further includes a first worm gear 8 and a first worm 7. The first worm gear 8 is rotatably disposed within the carrier plate 5 and is coaxial with the driving wheel 9. The first worm 7 is connected to the output end of the second motor 6 and meshes with the first worm gear 8. Driven by the second motor 6, the first worm gear 7 can drive the first worm gear 8 to rotate, thereby driving the driving wheel 9 to rotate synchronously.

[0063] In this embodiment, the second motor 6 drives the first worm 7 to rotate, thereby driving the first worm wheel 8 to rotate, thereby driving the driving wheel 9 to rotate synchronously.

[0064] The meshing transmission of the first worm 7 and the first worm wheel 8 has a large transmission ratio, which enables a large reduction ratio. Therefore, the rotational speed of the second motor 6 can be significantly reduced through the transmission of the first worm wheel 8 and the first worm 7, thereby meeting the low-speed rotation requirements of the driving wheel 9 and enabling the inspection platform 14 to move smoothly in the second direction. In addition, the meshing transmission of the first worm 7 and the first worm wheel 8 has a certain self-locking property, which can ensure that the first worm wheel 8 is self-locked when the second motor 6 is not in operation, thereby preventing the inspection platform 14 from moving on its own.

[0065] In some other embodiments, gear transmission may also be used.

[0066] Please also refer to Figure 1 and Figure 7 In some embodiments, a limiting groove 17 extending along the second direction is provided on the bottom surface of the maintenance platform 14 facing the supporting plate 5 , and the supporting plate 5 is provided with a limiting block 15 assembled in the limiting groove 17 .

[0067] The limiting block 15 is assembled in the limiting groove 17 to limit the inspection platform 14 from moving in other directions, that is, the inspection platform 14 can only move along the second direction, thereby preventing the inspection platform 14 from shaking or deflecting during movement.

[0068] It can be understood that in order to reduce the friction loss between the limit groove 17 and the limit block 15, a plurality of second balls 16 can be set on the surface of the limit block 15. The second balls 16 contact the inner surface of the limit groove 17, which can reduce the friction area of ​​the limit groove 17 and thus reduce the friction loss of the limit groove 17.

[0069] In some other embodiments, the maintenance platform 14 may be provided with a limiting block 15 , and the supporting plate 5 may be provided with a limiting groove 17 .

[0070] Please refer again Figure 1 In some embodiments, the base 1 is provided with a first threaded rod 3 connected to the output end of the first motor 2, and the bottom surface of the supporting plate 5 is provided with a slide rail 45 extending in the same direction as the first threaded rod 3. The telescopic link 4 includes two fixed ends 46 and two movable ends 47. The two fixed ends 46 are respectively provided on the base 1 and the supporting plate. One of the two movable ends 47 is provided on the first threaded rod 3 and threadably engaged with the first threaded rod 3, and the other is slidably provided on the slide rail 45.

[0071] In this embodiment, the first motor 2 drives the first threaded rod 3 to rotate, thereby driving the movable end 47 of the telescopic link 4 set on the first threaded rod 3 to move along the extension direction of the first threaded rod 3, so as to drive the other movable end 47 slidingly set on the slide rail 45 to slide along the slide rail 45. Under the movement of the two movable ends 47, the telescopic link 4 can drive the supporting plate 5 to rise and fall, thereby driving the maintenance platform 14 to rise and fall.

[0072] In some other embodiments, the first threaded rod 3 may also be replaced by a rod body with a smooth surface, and the first motor 2 may drive one of the movable ends 47 of the telescopic link 4 to move along the rod body.

[0073] Please refer again Figure 1 In some embodiments, the lifting frame 100 further includes a fixed seat 19, a fixed pulley 20, a clamping assembly 48, and a pull rope 21. The fixed seat 19 is disposed on a surface of the inspection platform 14 facing away from the load plate 5. The fixed pulley 20 is rotatably mounted on the fixed seat 19. The clamping assembly 48 is used to clamp a tool. The pull rope 21 is wound around the fixed pulley 20 and is capable of lifting the clamping assembly 48 when the clamping assembly 48 clamps a tool.

[0074] When the telescopic link 4 drives the load plate 5 to rise, the maintenance personnel may forget to use the tool. If the telescopic link 4 drives the load plate 5 to lower so that the maintenance personnel can pick up the tool and then drive the load plate 5 to rise again, the maintenance time will be extended. To solve this problem, the present embodiment is provided with a fixed pulley 20, and a pull rope 21 is wound around the fixed pulley 20, and the stretched end is connected to the clamping assembly 48. When the telescopic link 4 drives the load plate 5 to rise and the maintenance personnel forget to use the tool, the maintenance personnel can relax the stretched end away from the clamping assembly 48 and rotate the fixed pulley 20 to lower the clamping assembly 48 to the ground. After the ground staff clamps the tool with the clamping assembly 48, the maintenance personnel on the maintenance platform 14 pulls the other end of the pull rope 21 to raise the clamping assembly 48, so that the staff on the maintenance platform 14 can remove the tool.

[0075] By providing the pull rope 21 , the clamping assembly 48 can be lowered or lifted after the carrying plate 5 is raised, so that tools on the ground can be easily taken without lowering the carrying plate 5, thus avoiding delays in maintenance time.

[0076] In some other embodiments, a movable pulley 20 may be used instead of the fixed pulley 20 .

[0077] Please also refer to Figure 1 and Figure 8 Due to the weight of the clamping assembly 48, the other end of the pull rope 21 will automatically drop when it is in an active state. Therefore, in order to prevent the clamping assembly 48 from automatically dropping without the operation of the maintenance personnel, a clamping ring 35 can be connected to the end of the pull rope 21 away from the clamping assembly 48, and a winding wheel 33 and a clamping rod 34 are set on the supporting plate 5. When the clamping assembly 48 does not need to be lowered, the end of the pull rope 21 away from the clamping assembly 48 can be wound on the winding wheel 33, and the clamping ring 35 can be sleeved on the clamping rod 34, thereby limiting the movement of the clamping ring 35 and fixing the pull rope 21.

[0078] See also Figure 9 In some more specific embodiments, the clamping assembly 48 includes a connecting plate 22 and two pressure blocks 27, the connecting plate 22 is connected to the pull rope 21, the two pressure blocks 27 are both rotatably connected to the connecting plate 22, and the two pressure blocks 27 are configured to be able to clamp the tool between the two pressure blocks 27.

[0079] In this embodiment, the two pressing blocks 27 can abut against each other when the clamping assembly 48 is in an inoperative or operative state. When the clamping assembly 48 needs to clamp a tool, the two pressing blocks 27 rotate and move away from each other, forming a clamping space between the two pressing blocks 27. After the tool is placed in the clamping space, the two pressing blocks 27 rotate in opposite directions and move closer together, thereby clamping the tool between the two pressing blocks 27.

[0080] In some examples, both pressure blocks 27 are provided with a protrusion 29. When the two pressure blocks 27 clamp the tool, the protrusions 29 of the two pressure blocks 27 abut against the tool, thereby increasing the friction between the pressure blocks 27 and the tool, preventing the tool from falling when the clamping assembly 48 drives the tool up.

[0081] In some other more specific embodiments, the two pressing blocks 27 may also be slidably disposed on the connecting plate 22 .

[0082] Please continue reading Figure 9 In some more specific embodiments, the clamping assembly 48 further includes a rotating rod 23, a second worm 24, and two second worm gears 25. The rotating rod 23 is rotatably mounted on the connecting plate 22, the second worm 24 is connected to the rotating rod 23, and the two second worm gears 25 are rotatably mounted on the connecting plate 22 and are located on either side of the second worm 24. The two second worm gears 25 are meshed with the second worm 24 and are respectively connected to two pressing blocks 27. When the rotating rod 23 rotates, it drives the second worm 24 to rotate, which in turn drives the two second worm gears 25 to rotate, thereby driving the two pressing blocks 27 to rotate.

[0083] In this embodiment, when the clamping assembly 48 is lowered to the ground, the ground staff can rotate the rotating rod 23 to drive the second worm 24 to rotate. The rotation of the second worm 24 drives the two second worm gears 25 to rotate, thereby driving the two pressure blocks 27 to rotate and move the two pressure blocks 27 away from each other, thereby forming a clamping space between the two pressure blocks 27. After placing the tool in the clamping space, the ground staff rotates the rotating rod 23 in the opposite direction to drive the second worm 24 to rotate in the opposite direction. The reverse rotation of the second worm 24 drives the two second worm gears 25 to rotate in the opposite direction, thereby driving the two pressure blocks 27 to rotate in the opposite direction and move the two pressure blocks 27 closer to each other, thereby clamping the tool between the two pressure blocks 27.

[0084] In some examples, the clamping assembly 48 may also include two first connecting rods 26 and two second connecting rods 28, wherein one end of one of the first connecting rods 26 is connected to one of the second worm gears 25, and the other end is rotationally connected to one of the pressure blocks 27. Similarly, one end of one of the second connecting rods 28 is rotationally connected to the connecting plate 22, and the other end is rotationally connected to the pressure block 27. When the second worm gear 25 rotates, the first connecting rod 26 is driven to rotate around the end of the first connecting rod 26 connected to the second worm gear 25 as the rotation center, and the second connecting rod 28 is simultaneously driven to rotate around the end of the second connecting rod 28 connected to the connecting plate 22 as the rotation center, thereby driving the pressure block 27 to translate in space. Similarly, another first connecting rod 26 and another second connecting rod 28 can also drive another pressure block 27 to translate in space, which will not be described in detail here.

[0085] Please also refer to Figure 9 and Figure 10 In another example, the clamping assembly 48 may also include a pull rod 30, a clamping column 32 and a spring 31, wherein the pull rod 30 is connected to the clamping column 32 and is passed through one of the pressure blocks 27, and the two ends of the spring 31 are respectively connected to the clamping column 32 and the pressure block 27, and apply an elastic force to the clamping column 32 toward the other pressure block 27 to clamp the clamping column 32 with the other pressure block 27. When the clamping assembly 48 descends to the ground, the ground staff first applies a force to the pull rod 30 to overcome the elastic force applied by the spring 31 and separate the clamping column 32 from the other pressure block 27, and then rotates the rotating rod 23 to drive the two pressure blocks 27 away from each other and form a clamping space. After placing the tool in the clamping space, the rotating rod 23 is rotated in the opposite direction to drive the two pressure blocks 27 closer to each other. At the same time, the pull rod 30 is released, and the clamping column 32 passes through the tool in turn under the elastic force of the spring 31 and clamps with the other pressure block 27, thereby not only achieving the two pressure blocks 27 clamping the tool, but also achieving the clamping column 32 carrying the tool, thereby further improving the stability of the clamping assembly 48 clamping the tool and preventing the clamping assembly 48 from falling during the process of clamping the tool and rising.

[0086] In some other more specific embodiments, the second worm 24 may also be directly driven to rotate.

[0087] Please also refer to Figure 1 and Figure 11 In some embodiments, the lifting frame 100 further includes a housing 43, a cover 42, and a camera 40. The housing 43 is disposed on the maintenance platform 14, and the cover 42 is movably disposed on the top of the housing 43 and can selectively open or close the housing 43. The camera 40 is movably disposed inside the housing 43 and is configured to be able to move to the outside of the housing 43 when the cover 42 is opened.

[0088] When the camera 40 is not in operation, the housing 43 can protect the camera 40 and prevent the camera 40 from being accidentally damaged.

[0089] When maintenance personnel encounter a problem that cannot be handled immediately, they can operate the cover 42 to open the housing 43, so that the camera 40 can be moved from inside the housing 43 to outside the housing 43, so that the camera 40 can be used to capture the location where the problem occurs as a picture or image, which is convenient for subsequent feedback to professionals for guidance, thereby improving maintenance efficiency.

[0090] In some other embodiments, a through hole may be provided in the housing 43 so that the camera 40 can shoot through the through hole inside the housing 43 .

[0091] Please continue reading Figure 1 and Figure 11In some specific embodiments, there are two blocking covers 42, both of which are slidably mounted on top of the housing 43. The lifting frame 100 further includes a mounting plate 39 and two movable rods 41. The mounting plate 39 is movably mounted within the housing 43, and the camera 40 is mounted on the mounting plate 39. The two ends of one movable rod 41 are rotatably connected to one of the blocking covers 42 and the mounting plate 39, respectively. The two ends of the other movable rod 41 are rotatably connected to the other blocking cover 42 and the mounting plate 39, respectively. When the mounting plate 39 moves, the two movable rods 41 respectively drive the two blocking covers 42 to slide, thereby opening or closing the housing 43.

[0092] When maintenance personnel encounter a problem that cannot be handled immediately, the mounting plate 39 moves, driving the camera 40 to move. At the same time, the two movable rods 41 drive the two covers 42 to slide and move away from each other to open the housing 43, thereby enabling the camera 40 to move outside the housing 43 for shooting.

[0093] In some other more specific embodiments, the number of the blocking rod may also be one.

[0094] Please continue reading Figure 1 and Figure 11 In some more specific embodiments, the lifting frame 100 further includes a sleeve 38 and a second threaded rod 44. The sleeve 38 is connected to the mounting plate 39. The second threaded rod 44 is rotatably disposed within the housing 43 and is threadedly connected to the sleeve 38. The rotation of the second threaded rod 44 drives the sleeve 38 to move, thereby driving the mounting plate 39 to move.

[0095] When the second threaded rod 44 rotates, the sleeve 38 is driven to move along the axial direction of the second threaded rod 44 , thereby driving the mounting plate 39 to move.

[0096] In some examples, the lifting frame 100 also includes a bevel gear set 37 and a second connecting rod 36, wherein the bevel gear set 37 includes a first bevel gear and a second bevel gear that mesh with each other, the first bevel gear is coaxially arranged with the second threaded rod 44, the second bevel gear is connected to the second connecting rod 36, and when the second connecting rod 36 rotates, it drives the second bevel gear to rotate, and when the second bevel gear rotates, it drives the first bevel gear to rotate, thereby driving the second threaded rod 44 to rotate.
