Description

Technical Field

[0001] The invention relates to the technical field of magnetic levitation track construction, in particular to an aerial work platform for a magnetic levitation elevated section. Background Art

[0002] At present, general maglev train tracks are elevated, requiring operations such as power rail system installation, cable joint connection, and equipment adjustment to be performed on the upper and lower sides and sides of the track beam. Manual climbing and moving operations on the elevated maglev section are difficult, risky, and inefficient.

[0003] In order to solve the above problems, a specific construction platform is required. In the existing construction platform, workers move within the working frame of the construction platform, and the range of movement is small, which affects the construction work of workers on the side under the track beam. Summary of the invention

[0004] The present invention aims to provide an aerial work platform for a magnetically suspended elevated section, which can effectively solve the problems in the background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: an aerial work platform for a magnetic levitation elevated section, comprising a platform frame, four installation slots are respectively provided at the four corners of the platform frame, two frame travel mechanisms are respectively installed at the front and rear ends of the lower middle part of the platform frame, and the frame travel mechanism is located at the upper middle part of the T-shaped track beam, and also includes:

[0006] The frame anti-slip guide mechanism includes a guide control rod, each installation slot is connected to the top of the guide control rod through a rotating control component, a guide component is installed on the side of the middle of each guide control rod close to the T-shaped track beam, and a stable anti-slip component is installed on the bottom of each guide control rod;

[0007] The track beam side working platform mechanism is installed on the left and right sides of the platform frame, and the track beam side working platform mechanism is respectively installed with a platform expansion mechanism and an anti-falling insurance mechanism.

[0008] The platform frame serves as the main body of the aerial work platform. The four mounting slots are used to install four frame anti-slip guide mechanisms. The frame travel mechanism can realize the front and rear movement of the platform frame in the middle of the upper side of the T-track beam. The rotation control assembly is used to drive the guide control rod to rotate. When no materials are hoisted, the four rotation control assemblies drive the four guide control rods to approach the side of the T-track beam. At this time, the guide assembly on the guide control rod is in rolling contact with the side of the T-track beam, which can prevent the platform frame from tilting relative to the T-track beam and also allow the platform frame to move stably along the T-track beam when the frame travel mechanism is working. The two stable anti-slip guide mechanisms are used to prevent the platform frame from tilting relative to the T-track beam. The release components are rollingly connected to the bottom of both sides of the T-shaped track beam respectively, so as to improve the stability of the platform frame and the T-shaped track beam. The working platform mechanism on the side of the track beam serves as the activity area for the staff, which is convenient for the staff to work on both sides of the T-shaped track beam. The platform expansion mechanism can expand the activity area of ​​the staff, so that the activity area of ​​the staff extends to the lower sides of the T-shaped track beam, which is convenient for working on the lower sides of the T-shaped track beam. The anti-fall safety mechanism can support the power rail to be installed after lifting, so as to prevent the power rail from slipping off the sling when transferring to the lower sides of the T-shaped track beam, thereby protecting the staff.

[0009] Furthermore, the stable anti-slip assembly includes an anti-slip electric telescopic rod, each guide control rod is provided with a control groove on one side away from the T-shaped track beam, and a square hole is provided at the bottom of the guide control rod. The top of the control groove is fixedly connected to the top of the anti-slip sliding rod through a vertical anti-slip electric telescopic rod, the anti-slip sliding rod is slidably connected to the square hole, and the bottom of the anti-slip sliding rod is fixedly connected to an anti-slip wheel frame through the anti-slip rod, and an anti-slip wheel is rotatably installed on the anti-slip wheel frame, and the top of the anti-slip wheel is rollingly connected to the lower side of the T-shaped track beam.

[0010] When the rotating control assembly drives the guide control rod to approach the side of the T-track beam, the anti-slip electric telescopic rod extends, pushing the anti-slip sliding rod out of the control groove, and the guide assembly on the side of the guide control rod sticks to the side of the T-track beam. At this time, the guide control rod is in a vertical state, the anti-slip electric telescopic rod shortens, and the anti-slip sliding rod is pulled back into the control groove. The anti-slip rod, anti-slip wheel frame and anti-slip wheel move up with the anti-slip sliding rod until the top of the anti-slip wheel rolls in contact with the lower side of the T-track beam and stops. At this time, the platform frame is more stable when traveling on the upper side of the T-track beam, and the risk of tilting and slipping is smaller;

[0011] When it is necessary to hoist a longer material to the upper right side of the T-track beam, such as hoisting the wheel support rail, the two anti-slip electric telescopic rods on the right side are extended to allow the two anti-slip wheels on the right side to leave the lower right side of the T-track beam, and then the two rotating control components on the right side drive the two guide control rods on the right side to rotate counterclockwise, and the two guide control rods leave the right side of the T-track beam, and the hoisted wheel support rail passes through the area between the T-track beam and the two guide control rods until the bottom of the wheel support rail is higher than the upper side of the T-track beam and stops. At this time, the wheel support rail can be pushed to the middle of the upper side of the T-track beam to place the wheel support rail on the upper side of the T-track beam. The wheel support rail is also located below the platform frame at this time. During hoisting, the platform frame tends to tilt to the right due to the large downward influence of gravity on the right side, but the two anti-slip wheels on the left side of the platform frame are always close to the lower left side of the T-track beam, which can keep the platform frame stable on the T-track beam. A similar process is also used when it is necessary to hoist a longer material to the upper left side of the T-track beam.

[0012] Furthermore, the track beam side working platform mechanism includes a workbench, two side tie rods are fixedly connected to the left and right sides of the platform frame, the bottom of the two side tie rods on the same side are fixedly connected to the workbench, the upper edge of the workbench is fixedly connected to a U-shaped guardrail, the opening of the U-shaped guardrail faces the T-shaped track beam, and a U-shaped guard plate is provided on the inner side of the bottom of the U-shaped guardrail. The side tie rod is used to fix the workbench and the platform frame, the hoisted wheel support rail passes through the area between the side tie rod and the T-shaped track beam, the worker stands on the workbench, the U-shaped guardrail is used to protect the worker and prevent the worker from falling from the workbench, and the U-shaped guard plate can prevent tools or materials on the workbench from falling from the gap at the bottom of the U-shaped guardrail.

[0013] Furthermore, the platform expansion mechanism includes an expansion slide, a sliding groove is provided on the side of the workbench close to the T-track beam, and the expansion slide is connected to the slide in a transverse sliding manner, the bottom of the workbench is fixedly connected to the fixed end of the transverse expansion electric telescopic rod, and the telescopic end of the expansion electric telescopic rod is fixedly connected to the bottom of the expansion slide close to the T-track beam, the top of the expansion slide close to the T-track beam is fixedly connected to an inner baffle plate, the front and rear ends of the inner baffle plate are respectively fixedly connected to one end of two side guard plates on the side away from the T-track beam, and the two side guard plates are respectively connected to the guard plate grooves on the corresponding side pull rods in a transverse sliding manner. When installing the power rail, first lift the power rail, stop when the top of the power rail is close to the bottom of the side of the T-track beam, extend the electric telescopic rod, and push the extended slide out of the slide slot. The staff can move from the workbench to the upper side of the extended slide, allowing the staff to get closer to the T-track beam, expanding the working range and facilitating the installation of the power rail on the lower side of the T-track beam. The side guard plate and the inner baffle plate serve as guard plates to prevent tools or materials on the extended slide from falling from the edge of the extended slide.

[0014] Furthermore, the anti-falling safety mechanism includes a follow-up bending frame and a supporting protection beam. A rectangular guide groove is respectively provided in the middle of each side tie rod. A supporting protection beam is slidably connected in the rectangular guide groove. The bottom of the supporting protection beam close to the T-track beam is fixedly connected to the top of the follow-up bending frame. The bottom of the follow-up bending frame is fixedly connected to the corresponding inner baffle. When the extended slide extends out of the slide groove, the extended slide drives the two supporting protection beams close to the T-track beam through the inner baffle and the two follow-up bending frames. The tops of the two supporting protection beams correspond to the bottom of the power rail at this time, which can support the power rail and keep the power rail in a stable state, preventing the power rail from detaching from the sling and hitting the staff. It can also facilitate the installation of the power rail on the lower side of the T-track beam. At the same time, the two supporting protection beams can also serve as guardrails on the front and rear sides of the extended slide to prevent the staff from falling from the front and rear sides of the extended slide.

[0015] Furthermore, the anti-fall safety mechanism also includes a rectangular groove, a rotating shaft, an anti-slip block and a block flipping and retraction control assembly. A rectangular groove is provided at the top of one end of the supporting protection beam close to the T-track beam. A longitudinal rotating shaft is rotatably connected to the end of the rectangular groove close to the T-track beam. The rotating shaft is fixedly connected to one end of the anti-slip block, and the rotating shaft is connected to the block flipping and retraction control assembly.

[0016] Furthermore, the block flipping and retraction control assembly includes a core rod, a transverse rod groove is opened in the middle of the supporting protection beam, a core rod is transversely slidably connected in the rod groove, one end of the core rod extends into the rectangular groove and is fixedly connected to a transverse rack, a gear is fixedly connected to the rotating shaft, the gear and the rack are meshingly connected, the other end of the core rod extends to the outside of the rod groove and is fixedly connected to a safety button, and the part of the core rod between the safety button and the supporting protection beam is sleeved with a compression spring.

[0017] The elastic force of the compression spring pushes the safety button away from the supporting protection beam. At this time, the safety button pulls the rack through the core rod, and the meshing of the rack and the gear drives the rotating shaft to rotate until the side of the anti-slip block is blocked by the side of the rectangular groove close to the T-shaped track beam and stops. At this time, the anti-slip block is in a vertical state, and the top horizontal position of the anti-slip block is higher than the upper side of the supporting protection beam;

[0018] The anti-slip block can limit the rear side of the power rail supported on the supporting protection beam to prevent the power rail removed from the sling from detaching from the rear end of the supporting protection beam during installation.

[0019] After the power rail is installed on the lower side of the T-track beam, if the extended electric telescopic rod is shortened to allow the extended slide to retract into the slide slot, the two supporting protection beams will also be driven to gradually move away from the T-track beam. At this time, the side of the anti-slip block away from the T-track beam will hit the side of the installed power rail close to the T-track beam, blocking the extended slide from retracting into the slide slot, and the extended electric telescopic rod will stop working. Because there are usually two workers working together on a track beam side working platform mechanism, if the power rail is installed without paying attention to the workers standing on the extended slide and the extended slide is retracted into the slide slot, the workers are likely to fall from the side of the extended slide close to the T-track beam and be in danger, because two workers are required to control the extension slide to retract into the slide slot. Press and hold the two safety buttons at the ends of the two supporting protection beams to compress the two compression springs. At this time, the two core rods are close to the T-track beam, and through the meshing action of the two sets of racks and gears, the two anti-detachment blocks are driven to rotate toward the two rectangular grooves respectively until the two anti-detachment blocks are completely in the two rectangular grooves. At this time, the anti-detachment blocks will not be blocked by the installed power rails, and the two supporting protection beams can gradually move away from the T-track beam. The shortening of the extended electric telescopic rod will smoothly drive the extended slide to retract into the slide groove. Since the two supporting protection beams are far apart, one staff member cannot press and hold the two safety buttons at the same time to ensure that when the extended slide is retracted into the slide groove, both staff members are on the workbench, thereby adding an insurance, standardizing the behavior of operators, and improving safety.

[0020] Furthermore, it also includes an operation auxiliary mechanism, which includes a rotating drum, a longitudinal rail is fixedly connected to the upper side of the work table near the T-track beam, a sliding seat is slidably connected to the longitudinal rail, a longitudinal groove is opened in the middle of the upper side of the longitudinal rail, friction grooves are arranged in the longitudinal groove, a fixed sleeve is fixedly connected in the middle of the sliding seat, and the inner side of the fixed sleeve is rotatably connected to the bottom of the rotating drum, a side through groove is opened on the side surface of the middle part of the rotating drum, a sliding rod is vertically slidably connected in the side through groove, and the bottom of the side through groove is connected to the bottom of the sliding rod through a reset spring, one end of the sliding rod located in the rotating drum is fixedly connected to the top of the locking column, and the bottom of the locking column extends into the longitudinal groove, and one end of the sliding rod located on the outside of the rotating drum is fixedly connected to a horizontal seat plate, and a tool placement assembly is installed on the top of the rotating drum.

[0021] Under normal conditions, the return spring pushes the sliding rod upward in the side through slot, and the bottom end of the locking column does not contact the friction pattern in the longitudinal slot;

[0022] When installing the power rail, since the installation position of the power rail is on the lower side of the T-shaped track beam, the worker needs to look up to operate, which makes the work difficult. Therefore, an operation auxiliary mechanism is set. When the worker is standing to work, he can easily pull the top of the rotating drum to let the rotating drum slide along the longitudinal rail through the slide seat, which is convenient for taking and placing tools or materials in the tool placement assembly. When the worker needs to lower his posture to work, he can sit on the seat plate, and the seat plate drives the sliding rod to move down in the side groove. The reset spring is compressed, and the locking column moves down relative to the rotating drum. The bottom of the locking column contacts the friction pattern. Due to the friction force, the slide seat cannot slide along the longitudinal rail at this time, which is conducive to locking the seat plate position after sitting down, and the rotating drum can rotate relative to the fixed sleeve. The bottom of the locking column leaves the friction pattern, and the position of the seat plate can be easily moved or rotated. As a result, the worker can save the trouble of frequently bending over to pick up and put tools when standing, and can sit on the seat plate at any time when low-position operation is required, which saves the worker's physical strength during operation. This is suitable for operations that require equidistant point fixation on the power rail.

[0023] Furthermore, it also includes a power rail stable transverse movement control mechanism, the power rail stable transverse movement control mechanism includes an adjustment transverse sleeve, a lifting assembly is installed on the upper side of the workbench at the front end of the longitudinal rail, an adjustment transverse sleeve is installed on the side of the lifting assembly, a transverse support rail is connected in a transverse sliding manner in the adjustment transverse sleeve, and the transverse support rail is connected to the adjustment transverse sleeve through an extension control assembly, and a transverse push plate is installed on the upper side of the transverse support rail through a transverse movement push assembly, and the top horizontal position of the transverse push plate is higher than the upper side of the transverse support rail. The lifting assembly is used to drive the adjustment transverse sleeve and the transverse support rail to move up and down, and change the height of the transverse support rail. The extension control assembly is used to drive the transverse support rail to move left and right relative to the adjustment transverse sleeve, so that the transverse support rail can be close to the T-type track beam, so that the top of the transverse support rail supports the bottom of the longer material suspended, and the transverse movement push assembly can push the transverse push plate to move left and right relative to the transverse support rail, so that the longer material can be pushed to the T-type track beam, so that the longer material can be installed on the T-type track beam.

[0024] When installing the power rail, the transverse pushing assembly can push the power rail to the lower side of the T-shaped track beam through the transverse pushing plate. When installing the wheel support rail, the transverse pushing assembly can push the wheel support rail to the upper side of the T-shaped track beam through the transverse pushing plate, thereby improving the stability of the pushed material and avoiding danger to the operator when pushing.

[0025] Furthermore, it also includes a personnel tool lifting and transferring mechanism, which includes a lifting plate, a connecting plate and a step plate. A lifting plate is installed on the top of the adjusting horizontal sleeve, and the bottom of the lifting plate close to the middle of the worktable is fixedly connected to the step plate through a vertical connecting plate. Since the lifting assembly can drive the adjusting horizontal sleeve to move up and down, it can also drive the lifting plate, the connecting plate and the step plate to move up and down. The staff can stand on the lifting plate, and as the adjusting horizontal sleeve rises, the staff can transfer to the T-shaped track beam or platform frame as needed. Although the staff can climb with the help of the U-shaped guardrail, it will be inconvenient when carrying tools. Therefore, with the help of the lifting plate and the step plate, the tools can also be transferred to the T-shaped track beam or platform frame at the same time.

[0026] Compared with the prior art, the aerial work platform for the magnetic levitation elevated section has the following beneficial effects:

[0027] 1. The power rail is hoisted to a suitable height. The extension slide in the control platform extension mechanism is extended to drive the two supporting protection beams close to the T-track beam, so that the two supporting protection beams support the power rail. The transverse push assembly in the stable transverse movement control mechanism of the power rail can control the transverse push plate to push the power rail to the lower side of the T-track beam, so that the power rail is in a stable state during installation.

[0028] 2. The extension of the extension slide in the platform extension mechanism can also expand the range of activities of the staff, facilitate the construction work of the staff on the side under the track beam, and reduce the difficulty of the staff to install the power rail. At the same time, the two supporting protection beams can also protect the staff from falling off the power rail from the hoist and hitting the staff.

[0029] 3. When it is necessary to hoist longer materials such as wheel support rails to the upper side of the T-track beam, the rotary control component is used to control the two guide control rods on the same side to leave the side of the T-track beam, so that the wheel support rails and other longer materials can be hoisted to a position higher than the upper side of the T-track beam, and then the transverse push component is also used to control the transverse push plate to push the wheel support rails and other longer materials to the upper side of the T-track beam. This can prevent the guide components and stable anti-slip components in the frame anti-slip guide mechanism from interfering with the process of hoisting longer materials such as wheel support rails to the upper side of the T-track beam. At this time, although the hoisting side is subjected to greater force, the two stable anti-slip components on the non-hoisting side play a role, and the platform frame will not tilt and slide from the T-track beam to the hoisting side.

[0030] 4. When controlling the extension slide to retract into the slide groove, two workers are required to press the two safety buttons at the ends of the two supporting protection beams respectively to compress the two compression springs. At this time, the two core rods are close to the T-shaped track beam, and through the meshing action of the two sets of racks and gears, the two anti-detachment blocks are driven to rotate toward the two rectangular grooves respectively until the two anti-detachment blocks are completely in the two rectangular grooves. At this time, the anti-detachment blocks will not be blocked by the installed power rails, and the two supporting protection beams can be gradually moved away from the T-shaped track beam. The shortening of the extension electric telescopic rod will smoothly drive the extension slide to retract into the slide groove. Since the two supporting protection beams are far apart, one worker cannot press the two safety buttons at the same time to ensure that the two workers are on the workbench when the extension slide groove is retracted. This adds an insurance, standardizes the behavior of operators, and improves safety.

[0031] 5. When the staff is standing to work, they can easily pull the top of the rotating drum to let the rotating drum slide along the longitudinal rail through the slide seat, which is convenient for taking and placing tools or materials in the tool placement assembly. When the staff needs to lower their posture to work, they can sit on the seat plate, and the seat plate drives the sliding rod to move down in the side groove. The reset spring is compressed, and the locking column moves down relative to the rotating drum. The bottom of the locking column contacts the friction pattern. Due to the friction force, the slide seat cannot slide along the longitudinal rail at this time, which is conducive to locking the seat plate position after sitting down. When standing, it can save the trouble of workers frequently bending over to take and place tools. When low-position work is required, they can sit on the seat plate at any time, which is conducive to saving physical strength of workers during work. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] When the rotating control assembly drives the guide control rod 32 to approach the side of the T-track beam 14, the anti-slip electric telescopic rod 38 extends, pushing the anti-slip sliding rod 37 to extend out of the control groove 36, and the guide assembly on the side of the guide control rod 32 is attached to the side of the T-track beam 14. At this time, the guide control rod 32 is in a vertical state, the anti-slip electric telescopic rod 38 is shortened, and the anti-slip sliding rod 37 is pulled back into the control groove 36, and the anti-slip rod 39, the anti-slip wheel frame 310 and the anti-slip wheel 311 move up with the anti-slip sliding rod 37 until the top of the anti-slip wheel 311 rolls in contact with the lower side of the T-track beam 14 and stops. At this time, the platform frame 1 is more stable when traveling on the upper side of the T-track beam 14, and the risk of tilting and slipping is smaller.

[0055] When it is necessary to hoist a long material to the upper right side of the T-shaped track beam 14, such as hoisting a wheel support rail, the two anti-slip electric telescopic rods 38 on the right side are extended to allow the two anti-slip wheels 311 on the right side to leave the lower right side of the T-shaped track beam 14, and then the two rotation control components on the right side drive the two guide control rods 32 on the right side to rotate counterclockwise, and the two guide control rods 32 leave the right side of the T-shaped track beam 14, and the hoisted wheel support rail passes through the area between the T-shaped track beam 14 and the two guide control rods 32 until the bottom of the wheel support rail is higher than the upper side of the T-shaped track beam 14. The wheel support rail can be pushed toward the middle of the upper side of the T-track beam 14 to place the wheel support rail on the upper side of the T-track beam 14. The wheel support rail is also located below the platform frame 1 at this time. During hoisting, the platform frame 1 tends to tilt to the right due to the greater influence of gravity on the right side downward. However, the two anti-slip wheels 311 on the left side of the platform frame 1 are always close to the lower left side of the T-track beam 14, which can keep the platform frame 1 stable on the T-track beam 14. When it is necessary to hoist longer materials to the upper left side of the T-track beam 14, the process is similar.

[0056] The track beam side working platform mechanism 4 is installed on the left and right sides of the platform frame 1, and the track beam side working platform mechanism 4 is respectively installed with a platform expansion mechanism 5 and an anti-falling safety mechanism 6.

[0057] The track beam side working platform mechanism 4 includes a side tie rod 41, a workbench 42, a U-shaped guardrail 43 and a U-shaped guard plate 44. Two side tie rods 41 are fixedly connected to the left and right sides of the platform frame 1. The bottoms of the two side tie rods 41 on the same side are fixedly connected to the workbench 42. The upper edge of the workbench 42 is fixedly connected to the U-shaped guardrail 43. The opening of the U-shaped guardrail 43 faces the T-shaped track beam 14, and the bottom inner side of the U-shaped guardrail 43 is provided with a U-shaped guard plate 44. The side tie rod 41 is used to fix the workbench 42 and the platform frame 1. The hoisted wheel support rail passes through the area between the side tie rod 41 and the T-shaped track beam 14. The worker stands on the workbench 42. The U-shaped guardrail 43 is used to protect the worker and prevent the worker from falling from the workbench 42. The U-shaped guard plate 44 can prevent the tools or materials on the workbench 42 from falling from the gap at the bottom of the U-shaped guardrail 43.

[0058] The track beam side working platform mechanism 4 also includes a cross-beam rod 45. The front end tops of the two U-shaped guardrails 43 are fixedly connected by a transverse cross-beam rod 45, and the rear end tops of the two U-shaped guardrails 43 are fixedly connected by another transverse cross-beam rod 45. The two cross-beam rods 45 connect and fix the two U-shaped guardrails 43 to form a more stable whole. At the same time, the two cross-beam rods 45 serve as railings on the front and rear sides of the platform frame 1. If the staff needs to move to the outside of the platform frame 1, they can also tie the safety rope to the cross-beam rod 45.

[0059] The platform expansion mechanism 5 includes an expansion slide 51, a rod seat 53, an expansion electric telescopic rod 54, a connecting seat 55, a side guard plate 56 and an inner baffle plate 57. A slide groove is provided on the side of the workbench 42 close to the T-track beam 14, and the expansion slide plate 51 is connected to the slide groove for transverse sliding. The bottom of the workbench 42 is fixedly connected to the fixed end of the transverse expansion electric telescopic rod 54 through two rod seats 53. The telescopic end of the expansion electric telescopic rod 54 faces the T-track beam 14, and the telescopic end of the expansion electric telescopic rod 54 is fixedly connected to the bottom of the side of the expansion slide 51 close to the T-track beam 14 through the connecting seat 55. The top of the side of the expansion slide 51 close to the T-track beam 14 is fixedly connected to the inner baffle plate 57. The front and rear ends of the inner baffle plate 57 are fixedly connected to one end of two side guard plates 56 on the side away from the T-track beam 14, and the two side guard plates 56 are respectively connected to the corresponding guard plate grooves on the side pull rods 41 for transverse sliding. When installing the power rail 15, first lift the power rail 15, and stop when the top of the power rail 15 is close to the bottom of the side of the T-track beam 14, extend the electric telescopic rod 54, and push the extended slide 51 out of the slide groove. The staff can move from the workbench 42 to the upper side of the extended slide 51, allowing the staff to be closer to the T-track beam 14, thereby expanding the working range and facilitating the installation of the power rail 15 on the lower side of the T-track beam 14. The side guard plate 56 and the inner baffle plate 57 serve as guard plates to prevent tools or materials on the extended slide plate 51 from falling from the edge of the extended slide plate 51.

[0060] The platform expansion mechanism 5 also includes a slide bar 52. Two transverse slide bars 52 are fixedly connected to the bottom of the expansion slide plate 51. Two strip grooves cooperating with the slide bars 52 are provided at the bottom of the slide groove. With the help of the slide bars 52, the strength of the expansion slide plate 51 can be improved to prevent the expansion slide plate 51 from being deformed by gravity.

[0061] The anti-fall safety mechanism 6 includes a follow-up bent frame 61 and a supporting protective beam 62. A rectangular guide groove is opened in the middle of each side pull rod 41. The supporting protective beam 62 is horizontally slidably connected in the rectangular guide groove. The bottom of one end of the supporting protective beam 62 close to the T-shaped track beam 14 is fixedly connected to the top of the follow-up bent frame 61 by screws, and the bottom of the follow-up bent frame 61 is fixedly connected to the corresponding inner baffle plate 57. When the expansion slide 51 extends out from the slide groove, the expansion slide 51 drives the two supporting protection beams 62 to approach the T-track beam 14 through the inner baffle plate 57 and the two follower bending frames 61. The tops of the two supporting protection beams 62 correspond to the bottom of the power rail 15 at this time, which can support the power rail 15 and keep the power rail 15 in a stable state, thereby preventing the power rail 15 from detaching from the hanger and hitting the staff, and facilitating the installation of the power rail 15 on the lower side of the T-track beam 14. At the same time, the two supporting protection beams 62 can also serve as guardrails on the front and rear sides of the expansion slide 51 to prevent the staff from falling from the front and rear sides of the expansion slide 51.

[0062] The anti-fall safety mechanism 6 also includes a rectangular groove 63, a rotating shaft 64, an anti-slip block 65 and a block flipping and retraction control component. A rectangular groove 63 is provided at the top of one end of the supporting protection beam 62 close to the T-shaped track beam 14. A longitudinal rotating shaft 64 is rotatably connected to one end of the rectangular groove 63 close to the T-shaped track beam 14. The rotating shaft 64 is fixedly connected to one end of the anti-slip block 65, and the rotating shaft 64 is connected to the block flipping and retraction control component.

[0063] The block flipping and retraction control assembly includes a gear 66, a rack 67, a core rod 68, a safety button 69 and a compression spring 610. A transverse rod groove is provided in the middle of the supporting protection beam 62, and a core rod 68 is connected to the rod groove for transverse sliding. One end of the core rod 68 extends into the rectangular groove 63 and is fixedly connected to a transverse rack 67. A gear 66 is fixedly connected to the rotating shaft 64, and the gear 66 is meshed with the rack 67. A reserved hole is provided at one end of the supporting protection beam 62 close to the T-shaped track beam 14 corresponding to the position of the rack 67. The other end of the core rod 68 extends to the outside of the rod groove and is fixedly connected to the safety button 69. The part of the core rod 68 between the safety button 69 and the supporting protection beam 62 is sleeved with a compression spring 610.

[0064] The elastic force of the compression spring 610 pushes the safety button 69 away from the supporting protective beam 62. At this time, the safety button 69 pulls the rack 67 through the core rod 68, and the meshing of the rack 67 and the gear 66 drives the rotating shaft 64 to rotate until the side of the anti-detachment block 65 is blocked by the side of the rectangular groove 63 close to the T-shaped track beam 14. At this time, the anti-detachment block 65 is in a vertical state, and the top horizontal position of the anti-detachment block 65 is higher than the upper side of the supporting protective beam 62.

[0065] When the power rail 15 is hoisted, when the tops of the two supporting and protective beams 62 correspond to the bottoms of the power rail 15, the power rail 15 stops being hoisted, and the two supporting and protective beams 62 gradually approach the T-shaped track beam 14 as the expansion slide plate 51 extends out of the slide groove. When the top of the anti-slip block 65 encounters the side of the power rail 15 away from the T-shaped track beam 14, the power rail 15 will push the anti-slip block 65 to rotate with the rotating shaft 64 as the rectangular groove 63. At this time, the meshing action of the rack 67 and the gear 66 drives the core rod 68 to approach the T-shaped track beam 14, and the compression spring 610 is compressed. The beam 62 continues to approach the T-track beam 14 until the anti-slip block 65 completely passes the bottom of the power rail 15. At this time, the compression spring 610 stretches and resets, and the rack 67 is pulled to move by the core rod 68. The meshing action of the rack 67 and the gear 66 drives the rotating shaft 64 to rotate again until the side of the anti-slip block 65 is blocked by the side of the rectangular groove 63 close to the T-track beam 14. The anti-slip block 65 can limit the rear side of the power rail 15 supported on the supporting protection beam 62 to prevent the power rail 15 removed from the sling from detaching from the rear end of the supporting protection beam 62 during installation.

[0066] After the power rail 15 is installed on the lower side of the T-track beam 14, if the extended electric telescopic rod 54 is shortened to allow the extended slide 51 to retract into the slide groove, the two supporting protection beams 62 will also be driven to gradually move away from the T-track beam 14. At this time, the side of the anti-slip block 65 away from the T-track beam 14 will hit the side of the installed power rail 15 close to the T-track beam 14, blocking the extended slide 51 from retracting into the slide groove, and the extended electric telescopic rod 54 will stop working. Because there are usually two workers working together on a track beam side working platform mechanism 4, if the power rail 15 is installed without paying attention to the workers standing on the extended slide 51 and the extended slide 51 is retracted into the slide groove, the workers are likely to fall from the side of the extended slide 51 close to the T-track beam 14 and be in danger, because two workers are required to hold down the two respectively when controlling the extended slide 51 to retract into the slide groove. The two safety buttons 69 at the ends of the supporting and protective crossbeam 62 compress the two compression springs 610. At this time, the two core rods 68 are close to the T-track beam 14. Through the meshing action of the two sets of racks 67 and the gears 66, the two anti-detachment blocks 65 are driven to rotate toward the two rectangular grooves 63 respectively until the two anti-detachment blocks 65 are completely in the two rectangular grooves 63. At this time, the anti-detachment blocks 65 will not be blocked by the installed power rail 15, and the two supporting and protective crossbeams 62 can gradually move away from the T-track beam 14. The shortening of the extended electric telescopic rod 54 also smoothly drives the extended slide plate 51 to retract into the slide groove. Since the two supporting and protective crossbeams 62 are far apart, a staff member cannot press the two safety buttons 69 at the same time to ensure that the extended slide plate 51 is retracted into the slide groove. Both staff members are located on the workbench 42 to add an insurance, standardize the behavior of the operators, and improve safety.

[0067] When in use, the platform frame 1 serves as the main body of the aerial work platform, and the four mounting grooves 10 are used to install four frame anti-slip guide mechanisms 3. The frame travel mechanism 2 can realize the front and rear movement of the platform frame 1 in the middle of the upper side of the T-shaped track beam 14. The rotation control component is used to drive the guide control rod 32 to rotate. When no materials are hoisted, the four rotation control components drive the four guide control rods 32 to approach the side of the T-shaped track beam 14. At this time, the guide components on the guide control rods 32 are in rolling contact with the side of the T-shaped track beam 14, which can prevent the platform frame 1 from tilting relative to the T-shaped track beam 14, and can also allow the platform frame 1 to stably move along the T-shaped track beam 14 when the frame travel mechanism 2 is working. The two stable anti-slip components are respectively connected to the bottom of both sides of the T-shaped track beam 14 in a rolling manner, so as to improve the stability of the platform frame 1 and the T-shaped track beam 14. The track beam side working platform mechanism 4 serves as the activity area for the staff, which is convenient for the staff to work on both sides of the T-shaped track beam 14. The platform expansion mechanism 5 can expand the activity area of ​​the staff, so that the activity area of ​​the staff extends to the lower sides of the T-shaped track beam 14, which is convenient for working on the lower sides of the T-shaped track beam 14. The anti-fall safety mechanism 6 can support the power rail 15 to be installed after being lifted, so as to prevent the power rail 15 from slipping off the sling when transferring to the lower sides of the T-shaped track beam 14, thereby protecting the staff.

[0068] For example 2, please refer to Figures 1 to 12 This embodiment provides a technical solution: an aerial work platform for a magnetic levitation elevated section. The structure of this embodiment is roughly the same as that of the first embodiment, except that:

[0069] The aerial work platform for the elevated section of the magnetic levitation also includes an operation auxiliary mechanism 7, which includes a longitudinal rail 71, a longitudinal groove 72, a slide 73, a fixed sleeve 74, a rotating drum 75, a tool placement component, a seat plate 78, a sliding rod 79, a locking column 710, a side through groove 711 and a reset spring 712. The upper side of the workbench 42 is fixedly connected to the position near the T-shaped track beam 14, and the slide 73 is slidably connected to the longitudinal rail 71. The middle part of the upper side of the longitudinal rail 71 is provided with a longitudinal groove 72, and the longitudinal groove 72 is provided with friction lines. The middle part of the slide 73 is fixedly connected to a fixed groove. The fixed sleeve 74 and the inner side of the fixed sleeve 74 are rotatably connected to the bottom of the rotating cylinder 75. A side through groove 711 is opened on the middle side of the rotating cylinder 75. A sliding rod 79 is vertically slidably connected in the side through groove 711. The bottom of the side through groove 711 is connected to the bottom of the sliding rod 79 through a return spring 712. One end of the sliding rod 79 located in the rotating cylinder 75 is fixedly connected to the top of the locking column 710 by screws. The bottom of the locking column 710 extends into the longitudinal groove 72. One end of the sliding rod 79 located on the outside of the rotating cylinder 75 is fixedly connected to a horizontal seat plate 78. A tool placement assembly is installed on the top of the rotating cylinder 75.

[0070] The tool placement assembly includes a swivel 76 and a tool box 77. The swivel 76 is rotatably sleeved on the top of the rotating drum 75, and the tool box 77 is fixedly connected to the side of the swivel 76. The tool box 77 is used to place tools. The tool box 77 can be rotated relative to the rotating drum 75 through the swivel 76 to change the direction of the tool box 77, making it easier for workers to take tools and avoid frequent bending when taking tools.

[0071] Under normal conditions, the return spring 712 pushes the sliding rod 79 to move upward in the side through slot 711 , and the bottom end of the locking column 710 does not contact the friction pattern in the longitudinal slot 72 .

[0072] When installing the power rail 15, since the installation position of the power rail 15 is on the lower side of the side of the T-shaped track beam 14, the worker needs to look up to operate, which is difficult. Therefore, an operation auxiliary mechanism 7 is set. When the worker is standing to work, he can easily pull the top of the rotating drum 75 to allow the rotating drum 75 to slide along the longitudinal rail 71 through the slide seat 73, which is convenient for taking and placing tools or materials in the tool placement assembly. When the worker needs to lower his posture to work, he can sit on the seat plate 78, and the seat plate 78 drives the sliding rod 79 to move downward in the side groove 711, the return spring 712 is compressed, and the locking column 710 moves downward relative to the rotating drum 75. The bottom of the locking column 710 contacts the friction pattern. Due to the friction force, the slide seat 73 cannot slide along the longitudinal rail 71 at this time, which is conducive to locking the position of the seat plate 78 after sitting down, and the rotating drum 75 can move relative to the fixed The fixed sleeve 74 rotates, so that the seat plate 78 can be rotated relative to the fixed sleeve 74, changing the direction of the seat plate 78, which is convenient for the staff to use. The friction between the bottom of the locking column 710 and the friction pattern will also prevent the rotating drum 75 from rotating relative to the fixed sleeve 74. When the staff sits on the seat plate 78, it is not easy to rotate. Once the work is done, the return spring 712 returns to its original position and extends, pushing the sliding rod 79 to move up the side groove 711, and the bottom of the locking column 710 leaves the friction pattern. At this time, the position of the seat plate 78 can be easily moved, and the seat plate 78 can also be easily rotated. As a result, the staff can save the trouble of frequently bending over to pick up and put tools when standing, and can sit on the seat plate 78 at any time when low-level operations are required, saving the staff's physical strength during operation, which is suitable for operations that require equidistant point fixation on the power rail 15.

[0073] For example 3, please refer to Figures 1 to 12 This embodiment provides a technical solution: an aerial work platform for a magnetic levitation elevated section. The structure of this embodiment is roughly the same as that of the second embodiment, except that:

[0074] The aerial work platform for the elevated section of magnetic levitation also includes a power rail stable transverse movement control mechanism 8, which includes a lifting component, an extension control component, a transverse movement pushing component, an adjustment transverse sleeve 86, a transverse support rail 810, a transverse movement push plate 814 and a through groove 815. A lifting component is installed on the upper side of the workbench 42 at the front end of the longitudinal rail 71, and an adjustment transverse sleeve 86 is installed on the side of the lifting component. The adjustment transverse sleeve 86 is laterally slidably connected with the transverse support rail 810, and the transverse support rail 810 is connected to the adjustment transverse sleeve 86 through the extension control component, and a transverse movement push plate 814 is installed on the upper side of the transverse support rail 810 through the transverse movement pushing component, and the top horizontal position of the transverse movement push plate 814 is higher than the upper side of the transverse support rail 810, and a through groove 815 corresponding to the top of the transverse movement push plate 814 is opened in the top of the adjustment transverse sleeve 86.

[0075] The lifting assembly includes a vertical rail 81, a lead screw 82, a height adjustment motor 83, a slider 84, and a lead screw nut 85. The upper side of the workbench 42 is located at the front end of the longitudinal rail 71 and is fixedly connected to the bottom end of the vertical rail 81. The top of the vertical rail 81 is fixedly connected to the platform frame 1. The track groove of the vertical rail 81 faces the middle of the workbench 42. A vertical lead screw 82 is rotatably connected in the track groove of the vertical rail 81. The top of the lead screw 82 is fixedly connected to the height adjustment motor 83. The height adjustment motor 83 is installed on the top of the vertical rail 81. The track groove of the vertical rail 81 is vertically slidably connected to the slider 8 4. The middle part of the slider 84 is fixedly connected with a lead screw nut 85, which is connected with the lead screw 82. The end of the slider 84 is fixedly connected with the front side of the adjustment horizontal sleeve 86. The height adjustment motor 83 drives the lead screw 82 to rotate clockwise, and the threaded action of the lead screw 82 and the lead screw nut 85 allows the slider 84 to move upward along the track groove. The height adjustment motor 83 drives the lead screw 82 to rotate counterclockwise, and the threaded action of the lead screw 82 and the lead screw nut 85 allows the slider 84 to move downward along the track groove, thereby driving the adjustment horizontal sleeve 86 to move up and down.

[0076] The extension control assembly includes a seat ring 87, a transverse electric telescopic rod 88, and an end plate 89. The bottom of the adjustment transverse sleeve 86 is fixedly connected to the fixed end of the transverse electric telescopic rod 88 through two seat rings 87. The transverse electric telescopic rod 88 is laterally distributed, and the telescopic end of the transverse electric telescopic rod 88 faces the T-track beam 14. The telescopic end of the transverse electric telescopic rod 88 is fixedly connected to the end of the transverse support rail 810 close to the T-track beam 14 through the end plate 89. When the transverse electric telescopic rod 88 is extended or retracted, the transverse support rail 810 is driven to move left and right relative to the adjustment transverse sleeve 86 through the end plate 89. In order to prevent the inner baffle plate 57 from interfering with the up and down movement of the transverse support rail 810, a notch 58 is provided on the inner baffle plate 57 at the position corresponding to the transverse support rail 810.

[0077] The transverse push assembly includes a lead screw 811, a transverse control motor 812, and a lead screw nut 813. The transverse lead screw 811 is rotatably connected in the track groove on the upper side of the transverse support rail 810. The track groove on the upper side of the transverse support rail 810 slides transversely in the track groove to connect the bottom of the transverse push plate 814. The bottom of the transverse push plate 814 is fixedly connected with a lead screw nut 813. The lead screw nut 813 is matched with the lead screw 811. The end of the lead screw 811 away from the T-shaped track beam 14 is fixedly connected to the output shaft of the transverse control motor 812. The transverse control motor 812 is installed at the end of the transverse support rail 810 away from the T-shaped track beam 14. The movement control motor 812 drives the lead screw 811 to rotate clockwise, and the threaded action of the lead screw 811 and the lead screw nut 813 drives the transverse push plate 814 to move left along the track groove on the upper side of the transverse support rail 810. The transverse control motor 812 drives the lead screw 811 to rotate counterclockwise, and the threaded action of the lead screw 811 and the lead screw nut 813 drives the transverse push plate 814 to move right along the track groove on the upper side of the transverse support rail 810, thereby driving the transverse push plate 814 to move left and right. When the transverse push plate 814 is close to the T-shaped track beam 14, it can push the lifted material close to the T-shaped track beam 14, which is convenient for the installation of the material on the T-shaped track beam 14.

[0078] The lifting assembly is used to drive the adjustment transverse sleeve 86 and the transverse support rail 810 to move up and down, thereby changing the height of the transverse support rail 810. The extending control assembly is used to drive the transverse support rail 810 to move left and right relative to the adjustment transverse sleeve 86, so that the transverse support rail 810 can be close to the T-shaped track beam 14, so that the top of the transverse support rail 810 can support the bottom of the longer material being suspended. The transverse pushing assembly can push the transverse pushing plate 814 to move left and right relative to the transverse support rail 810, so that the longer material can be pushed toward the T-shaped track beam 14, making it easier for the longer material to be installed on the T-shaped track beam 14.

[0079] When installing the power rail 15, the transverse pushing assembly can push the power rail 15 toward the lower side of the T-shaped track beam 14 through the transverse pushing plate 814. When installing the wheel support rail, the transverse pushing assembly can push the wheel support rail toward the upper side of the T-shaped track beam 14 through the transverse pushing plate 814, thereby improving the stability of the pushed material and avoiding danger to the operator when pushing.

[0080] The aerial work platform for the elevated section of the magnetic levitation also includes a personnel and tool lifting and transferring mechanism 9, which includes a lifting plate 91, a connecting plate 92 and a step plate 93. The top of the adjustment cross sleeve 86 is installed with a horizontal lifting plate 91 by screws, and the bottom of the lifting plate 91 close to the middle of the workbench 42 is fixedly connected with a horizontal step plate 93 by a vertical connecting plate 92. Since the lifting component can drive the adjustment cross sleeve 86 to move up and down, it can also drive the lifting plate 91, the connecting plate 92 and the step plate 93 to move up and down, and the staff can stand on the lifting plate 91. As the adjustment cross sleeve 86 rises, the staff can transfer to the T-shaped track beam 14 or the platform frame 1 as needed. Although the staff can climb with the help of the U-shaped guardrail 43, it will be inconvenient when carrying tools. Therefore, with the help of the lifting plate 91 and the step plate 93, the tools can also be transferred to the T-shaped track beam 14 or the platform frame 1 at the same time.

[0081] It is worth noting that the hoist 13 disclosed in the above embodiment adopts an electric hoist, the control motor 33 adopts a servo motor with a self-locking function, the height adjustment motor 83 and the transverse movement control motor 812 both adopt servo motors, the power motor 24, the control motor 33, the anti-slip electric telescopic rod 38, the extended electric telescopic rod 54, the height adjustment motor 83, the transverse movement electric telescopic rod 88, the transverse movement control motor 812 and the hoist 13 are all controlled by an external PLC controller, and the control method adopts the method commonly used in the prior art.
