Description

Technical Field

[0001] The present invention relates to the technical field of equipment for medium and low speed maglev transportation track systems, and particularly relates to a comprehensive operation vehicle and working method for disassembling and assembling in-station tracks of medium and low speed maglev transportation. Background Art

[0002] Medium and low speed maglev transportation is a complex systems engineering, and both the vehicles and maglev tracks are new technologies. Among them, the maglev track that supports the operation of maglev vehicles is one of the key components of the line equipment. It is mainly composed of track beams, rail supports, F-shaped steel guide rails, aluminum induction plates, H-shaped steel sleepers, and joints connected by fasteners. Similar to the steel rails of wheel-rail systems, it has to bear the functions of supporting the vehicle and guiding the vehicle. However, due to the load distribution along the vehicle length and its topological relationship, its structure has its own uniqueness (asymmetric F-shaped structure). When the vehicle is running, the train and the track achieve contactless suspension and guidance through electromagnetic force, and use the electromagnetic force generated by the linear motor to achieve traction operation. There is no contact between the maglev vehicle body and the track, but when the vehicle enters the station, electromagnetic braking and mechanical braking will be activated to enable the vehicle to stop smoothly and accurately.

[0003] During daily operation, various reasons such as frequent mechanical braking will cause relatively serious wear and deformation of the track braking surface, affecting the use safety of the vehicle system. Therefore, it is necessary to regularly overhaul and replace the maglev track in the station and then repair and transform it offline. Currently, there is no dedicated and mature equipment for reference. When using ordinary equipment and tools for hoisting and replacement maintenance, due to the limited space environment in the station and the structural characteristics that there is no walking surface for the vehicle before and after the track replacement, the equipment cannot enter, resulting in the inability to carry out the overhaul and replacement or low efficiency, increasing the construction cost, and unable to achieve the mechanized and engineering disassembly and replacement of the maglev track, seriously restricting the improvement of the on-site construction efficiency and construction quality. Therefore, it is necessary to design a comprehensive operation vehicle and working method for disassembling and assembling in-station tracks of medium and low speed maglev transportation to solve the problems that ordinary equipment and lifting tools cannot walk and support in the disassembly and assembly of in-station maglev tracks and the disassembly and assembly efficiency is low in the prior art. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a comprehensive operation vehicle and working method for disassembling and assembling in-station tracks of medium and low speed maglev transportation.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a comprehensive operation vehicle for disassembling and assembling in-station tracks of medium and low speed maglev transportation, including a suspension trolley and a rail transport trolley. The suspension trolley includes a suspension vehicle body frame, 2 groups of monorail cranes, 4 groups of guiding and positioning mechanisms, and a suspension wheel lifting system. The monorail cranes are installed on the front and rear sides of the suspension vehicle body frame, and the guiding and positioning mechanisms are installed at the bottom of the suspension support arms of the suspension vehicle body frame. The guiding and positioning mechanisms control the suspension trolley to suspend on the old F-shaped guide rail.

[0006] A rail transport trolley is arranged on the rail of the old F-shaped rail. The rail transport trolley is located below the inner side of the suspension crane body frame, and the new F-shaped rail is placed on the rail transport trolley.

[0007] Specifically, the suspension crane body frame includes a suspension crane support arm, a single-rail beam, a connecting upper beam, a connecting lower beam, and a suspension crane connecting bracket. The single-rail beam and the connecting upper beam are relatively fixed to form an upper frame. The upper part of the suspension crane connecting bracket is fixed to the bottom of the upper frame, and the lower part of the suspension crane connecting bracket is connected inside the suspension crane support arm. A connecting lower beam is provided between the suspension crane support arms on the same side.

[0008] Specifically, a single-rail crane is installed on the single-rail beam. The single-rail crane is provided with a lifting mechanism and an electric control system box, and the electric control system box controls the operation of the lifting mechanism.

[0009] Specifically, a suspension wheel lifting system is installed on the suspension crane support arm. A suspension crane traveling drive mechanism is installed below the suspension wheel lifting system. The drive wheels of the suspension crane traveling drive mechanism are located above the old F-shaped rail. The suspension wheel lifting system controls the lifting of the suspension crane traveling drive mechanism. The suspension crane traveling drive mechanism and the old F-shaped rail are in two modes of "contact" or "non-contact", corresponding to two states of the suspension trolley of "traveling" or "temporarily stopping and fixing".

[0010] Specifically, the guiding and positioning mechanism includes a horizontally extending support frame, a horizontally telescopic drive motor, a horizontally V-shaped telescopic drive motor, an inclined sliding part drive motor, an extended limit plate drive shaft, an extended limit plate, a suspension crane accommodation support groove, a special-shaped moving support arm, and a screw rod. The suspension crane accommodation support groove is fixed to the bottom of the suspension crane support arm. The horizontally extending support frame is slidably connected inside the suspension crane accommodation support groove. A horizontally telescopic drive motor is installed at the outer end of the horizontally extending support frame. The horizontally telescopic drive motor drives the horizontally extending support frame to move horizontally in the suspension crane accommodation support groove. When the suspension trolley is in the state of "temporarily stopping and fixing", the horizontally extending support frame extends inward into the gap of the rail support table on the upper part of the track beam for positioning the suspension trolley.

[0011] Specifically, a screw rod is installed at the bottom of the suspension crane accommodation support groove. A horizontally V-shaped telescopic drive motor is installed at the outer end of the screw rod. A special-shaped moving support arm is threadedly connected to the screw rod. The horizontally V-shaped telescopic drive motor drives the special-shaped moving support arm to move horizontally. An inclined sliding part drive motor is installed on the special-shaped moving support arm. The inclined sliding part drive motor drives the connection of the extended limit plate drive shaft. The upper part of the extended limit plate drive shaft is installed with an extended limit plate. The inclined sliding part drive motor drives the axial expansion and contraction of the extended limit plate. The extended limit plate drive shaft makes the extended limit plate move. When the suspension trolley is in the state of "traveling", the extended limit plate has no contact and no friction with the track beam. When the suspension trolley is in the state of "temporarily stopping and fixing", the extended limit plate is clamped with the track beam.

[0012] Specifically, when the suspension trolley is in the "traveling" state, the suspension wheel lifting system lifts the suspension trolley, and then the operation mode of starting the traveling drive mechanism of the overhead crane is adopted; when the suspension trolley is in the "temporary stop and fixation" state, the transverse telescopic drive motor makes the transverse extension support frame telescopically move horizontally to fit with the track beam to form a support operation mode.

[0013] Specifically, the rail transport trolley includes a driving traveling mechanism, a limit support, an F-shaped guide rail horizontal bracket, and a vehicle frame. The driving traveling mechanism is installed inside the driving wheels, the vehicle frame is installed on the driving wheels, and a limit support and an F-shaped guide rail horizontal bracket are provided on the upper part of the vehicle frame for placing the new F-shaped guide rail. Both the driving traveling mechanism and the traveling drive mechanism of the overhead crane are internally provided with servo motors with braking functions, and a transmission mechanism is arranged between the output shaft of the servo motor and the driving wheels.

[0014] Specifically, the driving wheels of the traveling drive mechanism of the overhead crane are arranged on the aluminum induction plate of the old F-shaped guide rail, the driving wheels of the driving traveling mechanism are arranged on the traveling surface of the old F-shaped guide rail, and guiding mechanisms are arranged on both sides of the suspension trolley. The guiding mechanisms cooperate with the outer magnetic pole sides of the old F-shaped guide rail for the guiding mechanisms to travel on the traveling surface of the track beam.

[0015] A working method for a comprehensive operation vehicle for disassembling and assembling the inner track of medium and low-speed maglev transportation includes the following steps:

[0016] 1) The suspension trolley is in place, the electric control system box is operated, the transverse V-shaped telescopic drive motor and the tilt sliding part drive motor are started to drive the special-shaped moving support arm to move to a safe position, so that the extended limit plate has no contact with the track beam and no longer "clamps" the track beam;

[0017] 2) The suspension wheel lifting system is started to place the traveling drive mechanism of the overhead crane on the old F-shaped guide rail, lift the suspension trolley to a certain height, check the heights of the 4 transverse extension support frames so that their lower surfaces no longer fit with the upper surface of the track beam, the suspension trolley is lifted upward, and a safety distance of more than 10 - 20 mm is maintained;

[0018] 3) The transverse telescopic drive motor is started to make the transverse extension support frame move horizontally outward to both sides of the track beam along the accommodation support groove of the overhead crane until the end of the transverse extension support frame moves to a position 10 - 20 mm away from both sides of the track beam;

[0019] 4) At this time, the suspension trolley is in a "traveling" state, the traveling drive mechanism of the overhead crane is started to drive the suspension trolley forward. After the suspension trolley is driven to the operation area where the old F-shaped guide rail needs to be replaced, the electric control system box of the suspension trolley is operated in the reverse steps of the above experimental steps. The transverse telescopic drive motor is started in sequence, and the suspension wheel lifting system is started to make the suspension trolley in the "temporary stop and fixation" state. Subsequently, the rail transport trolley transports the new F-shaped guide rail 5 to this suspension trolley;

[0020] 5) At this time, adjust the positions of the monorail crane and the hook through the electric control system box. For the single-sided replacement of the new F-shaped guide rails on both sides of the same rail panel, bind the old F-shaped guide rails to be disassembled with lifting straps, remove the connecting bolts between the old F-shaped guide rails and the H-shaped steel of the sleeper, start the hoisting mechanism, and lift the old F-shaped guide rails onto the rail transport trolley; then adjust the positions of the monorail crane and the hook through the electric control system box to install the new F-shaped guide rails at the position of the above-mentioned old F-shaped guide rails, and tighten the connecting bolts; repeat the above actions to complete the replacement of the old F-shaped guide rails on the other side of the rail panel. During the installation process, the connection between the new F-shaped guide rails and the existing sleepers, the gauge adjustment, and the torque should be adjusted according to the technical parameters of the rail panel.

[0021] 6) According to the operation requirements, the rail transport trolley exits this operation area through the operation of the electric control system box and travels to the next operation area or stops for operation; the suspended trolley starts the "walking" state through the operation of the electric control system box and travels to the next operation area or stops for operation. The actions of the suspended trolley and the rail transport trolley cooperate with each other to form a cyclic operation mode. By analogy, the comprehensive operation of track disassembly and assembly in the station can be completed.

[0022] The present invention has the following beneficial effects:

[0023] The comprehensive operation vehicle and working method for track disassembly and assembly in the medium and low speed maglev transportation station designed by the present invention avoid the disadvantages in the existing technical equipment that ordinary equipment and tools cannot be used for hoisting, replacement and maintenance in the medium and low speed maglev transportation station, and minimize the impact on the construction site of track maintenance offline replacement;

[0024] The structure of this comprehensive operation vehicle is simple and reasonable, easy to install and disassemble, the construction replacement method is easy to operate, safe and reliable to use, and has good economic benefits. It solves the practical problem of replacement in the medium and low speed maglev track station, and the construction cost is relatively low. A series of servo motors are used to drive instead of manual operation to complete track maintenance and replacement, making up for the gap in track maintenance and replacement in the domestic maglev rail transit system station, and greatly improving the construction efficiency.

Specific embodiments

[0036] Hereinafter, the technical solutions in the embodiments of the present invention will be further described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0037] As Figure 1-6 shown, a comprehensive operation vehicle for the disassembly and assembly of the inner-rail of medium and low-speed maglev transportation includes a suspension trolley and a rail transport trolley 4. The suspension trolley mainly includes a single-rail crane 7, an electric control system, a driving and traveling mechanism, a suspension crane body frame, a guiding and positioning mechanism, etc. The whole vehicle is powered by a storage battery and has no noise pollution.

[0038] The suspension crane body frames are symmetrically arranged on both sides, and the bottom can be transversely telescoped by a drive motor to make the laterally extending support frame 11 fit with the rail beam 1 to form a temporary support and consolidation; the laterally extending support frame 11 of the suspension crane body frame is a linear slide rail drive, and the transmission of the extension limit plate 20 and the special-shaped moving support arm 23 is a screw rod drive structure, both of which can be stably driven.

[0039] At the bottom of the suspension trolley and the main body of the rail transport trolley, there is a driving and traveling structure, which is provided with multiple groups of driving wheels. The inside of the driving wheels is composed of a servo motor with a braking function. There is a transmission mechanism between the output shaft of the servo motor and the said driving wheels. The servo motor is connected to the electric control system box 7.2 of the new maintenance vehicle.

[0040] The suspension trolley body is composed of a suspension crane support arm 6, a connecting lower beam 18, a suspension crane connecting bracket 22, a single-rail beam 8, a connecting upper beam 9, and bolt connections, and is set and fixed on the suspension crane accommodation support groove 21; the driving and traveling mechanism is arranged at the front and rear ends of the vehicle body. There are multiple guiding mechanisms 15 and they are arranged on both sides of the vehicle body and cooperate with the outer magnetic pole side of the old F-shaped guide rail 3. The driving and traveling mechanism wheels are provided with rubber pads. On the one hand, it protects the aluminum induction plate on the old F-shaped guide rail 3 from being damaged by pressure, and on the other hand, it improves the contact friction resistance between the driving and traveling mechanism wheels and the aluminum induction plate on the old F-shaped guide rail 3, so as to realize safe traveling on the running surface of the old F-shaped guide rail 3 on the track beam 1.

[0041] The suspension crane accommodation support groove 21 matches the width of the track beam 1, and there is a certain safety distance in the transverse direction between the two ends of the track beam 1.

[0042] The suspension trolley controls the lifting of the trolley through the suspension wheel lifting system 10, and further drives the driving and traveling mechanism to be in two modes of "contact" and "non-contact" with the old F-shaped guide rail 3. Further, the suspension trolley can be in two states of "traveling" and "temporarily stopping and fixing".

[0043] The suspension trolley is provided with an extended limit plate 20. The extended limit plate drive shaft 19 can make the extended limit plate 20 extend and move. When the suspension trolley is in the "traveling" state, the extended limit plate 20 has no contact and no friction with the bridge. When the suspension trolley is in the "temporarily stopping and fixing" state, the extended limit plate 20 is clamped with the track beam 1 to prevent the suspension trolley from tipping over due to the center of gravity deviation when hoisting the F-shaped guide rail.

[0044] The rail transport trolley 4 is composed of a driving and traveling mechanism 17, a limit support 4.1, an F-shaped guide rail horizontal bracket 4.2, and a vehicle frame 4.3; the F-shaped guide rail horizontal bracket 4.2 plays a role in supporting and lifting the new and old F-shaped guide rails during use; the limit support 4.1 has the functions of limiting and restricting the space conditions at the installation location, restricting the lateral displacement of the F-shaped guide rail along the line.

[0045] The wheels of the driving and traveling mechanism 17 of the rail transport trolley 4 have a limit guiding function and cooperate with the outer running surface of the old F-shaped guide rail 3 to support and limit the positions of the left and right sides of the wheels of the driving and traveling mechanism 17 within the end face of the old F-shaped guide rail 3, so that the positions of the wheels of the driving and traveling mechanism 17 are stable. The electric control system is integrated with the suspension trolley, so that the rail transport trolley 4 travels along the track direction. Its width (transverse) does not interfere with the suspension trolley, preventing it from derailing and ensuring safe operation.

[0046] The monorail crane 7 is arranged on the monorail beam 8 of the suspended trolley. The monorail crane 7 moves horizontally along the wing plate of the monorail beam 8, and there is a safety limit switch at the end of the monorail beam 8. There are two monorail cranes 7, which move synchronously and lift and lower synchronously during operation.

[0047] A working method of a comprehensive operation vehicle for disassembling and assembling the inner track of medium and low speed maglev transportation, the steps are as follows:

[0048] See Figure 1 As shown, according to an implementation form of the comprehensive operation vehicle for disassembling and assembling the inner track of medium and low speed maglev transportation provided by the present invention, the comprehensive operation vehicle includes a suspended trolley and a rail transport trolley 4. The components are lifted by a crane to a position outside the station at a safe distance, and after on-site assembly and installation, step-by-step operations are carried out. The steps of erecting and assembling the suspended trolley on both sides of the track beam 1 are as follows:

[0049] When erecting and assembling the suspended trolley, the horizontally extending support frame 11, the horizontally telescopic drive motor 12 and the suspended crane accommodation support groove 21 are assembled into a linear slide rail. After the inclined sliding part drive motor 14, the extended limit plate drive shaft 19 and the extended limit plate 20 are assembled into one body, they are assembled with the screw rod 24 and the horizontally V-shaped telescopic drive motor 13 through the special-shaped moving support arm 23 to form 4 components.

[0050] See Figure 2 、 Figure 6 As shown, the above 4 components assembled by the suspended trolley are evenly and symmetrically arranged on both sides of the track beam 1 according to the installation dimension requirements, and are placed on the pre-prepared brackets and sleepers. By adjusting the positional relationship between the horizontally extending support frame 11 and the suspended crane accommodation support groove 21, each horizontally extending support frame 11 is supported on the upper surface of the track beam 1 between two track-bearing platforms 2 in the line direction (longitudinal), and the gap between the guiding mechanism 15 and the old F-shaped guide rail 3 is checked to ensure that the guiding function is complete, so as to prepare for installing other upper components.

[0051] See Figure 3 As shown, further, in an open and safe area outside the station, the suspended crane support arm 6, the monorail beam 8, the connecting upper beam 9, the suspended wheel lifting system 10, the guiding mechanism 15, the suspended crane running drive mechanism 16, the connecting lower beam 18, and the suspended crane connecting bracket 22 are assembled into a frame structure, and then the monorail crane 7, the lifting mechanism 7.1 and the electric control system box 7.2 are installed. The whole is lifted by a crane onto the 4 components and assembled into a suspended trolley through bolt connection.

[0052] Regarding the assembled suspension trolley, it should be noted that during the initial installation, by adjusting the height of the suspension wheel lifting system 10, the suspension trolley is in a "non-contact" mode with the old F-shaped guide rail 3, and the traveling drive mechanism 16 of the suspension crane is "suspended off the ground"; adjust the position of the extended limit plate 20 and fix it tightly with the track beam 1, that is, the suspension trolley is in a "temporary stop and fixation" state.

[0053] See Figure 4 、 Figure 6 As shown, use a truck crane to place the rail transport trolley 4 on the running surface of the old F-shaped guide rail 3 of the vehicle track system near the above-mentioned suspension trolley. The four driving and traveling mechanisms 17 of the rail transport trolley 4 are limited within the end face of the old F-shaped guide rail 3 and will not fall off. Subsequently, lift the new F-shaped guide rail 5 and place it on the F-shaped guide rail horizontal bracket 4.2 of the rail transport trolley 4 for standby.

[0054] The operation steps of the track disassembly and assembly integrated operation vehicle are specifically as follows:

[0055] (1) Position the suspension trolley, operate the electric control system box 7.2, start the horizontal V-shaped telescopic drive motor 13 and the tilt sliding part drive motor 14 to drive the special-shaped moving support arm 23 to move to a safe position, so that the extended limit plate 20 has no contact with the track beam 1 and no longer "clamps" the track beam 1.

[0056] (2) Start the suspension wheel lifting system 10, lower the traveling drive mechanism 16 of the suspension crane onto the old F-shaped guide rail 3, lift the suspension trolley to a certain height, check the height of the four horizontal extension support frames 11 so that their lower surfaces no longer fit the upper surface of the track beam 1, and the suspension trolley is lifted upward and is at a safe distance of more than 10 - 20 mm.

[0057] (3) Start the horizontal telescopic drive motor 12 to make the horizontal extension support frame 11 move laterally outward from both sides of the track beam 1 along the suspension crane accommodation support groove 21 until the end of the horizontal extension support frame 11 moves to a position 10 - 20 mm away from both sides of the track beam 1.

[0058] (4) At this time, the suspension trolley is in a "traveling" state. Start the traveling drive mechanism 16 of the suspension crane to drive the suspension trolley forward. After driving the suspension trolley with the new F-shaped guide rail 5 to the operation area where the old F-shaped guide rail 3 needs to be replaced, after completing the above experimental steps, operate the electric control system box 7.2 of the suspension trolley in the reverse steps, start the horizontal telescopic drive motor 12 in sequence, start the suspension wheel lifting system 10 to make the suspension trolley in a "temporary stop and fixation" state, and then the rail transport trolley 4 transports the new F-shaped guide rail 5 to this suspension trolley.

[0059] (5) At this time, the position of the single-rail crane 7 and the hook is adjusted through the electric control system box 7.2. For the single-sided replacement of the new F-shaped guide rails 5 on both sides of the same track row, the old F-shaped guide rail 3 to be disassembled is tied well with a lifting belt, the connecting bolts between the old F-shaped guide rail 3 and the sleeper H-shaped steel are removed, the hoisting mechanism 7.1 is started, and the old F-shaped guide rail 3 is lifted and placed on the rail transport trolley 4; then the position of the single-rail crane 7 and the hook is adjusted by the electric control system box 7.2 to install the new F-shaped guide rail 5 at the position of the old F-shaped guide rail 3 mentioned above, and the connecting bolts are tightened. Repeat the above actions to complete the replacement of the old F-shaped guide rail 3 on the other side of the track row. During the installation process, the connection between the new F-shaped guide rail 5 and the existing sleepers, the track gauge adjustment, and the torque should be adjusted according to the technical parameters of the track row.

[0060] According to the operation requirements, the rail transport trolley 4 exits this operation area through the operation of the electric control system box 7.2 and travels to the next operation area (or stops for operation); the suspension trolley starts the "walking" state through the operation of the electric control system box 7.2 and travels to the next operation area (or stops operating). The actions of the suspension trolley and the rail transport trolley 4 cooperate with each other to form a cyclic action mode. By analogy, the comprehensive operation of track disassembly and assembly in the station can be completed.

[0061] It should be further noted that during the actual use of the suspension wheel lifting system 10, the lateral telescopic drive motor 12, the lateral V-shaped telescopic drive motor 13, the tilt sliding part drive motor 14, the suspension crane traveling drive mechanism 16, the drive traveling mechanism 17, and the hoisting mechanism 7.1 in the electric control system box 7.2, it is composed of three switches. Each group of switches includes green, red, and stop buttons to control its moving direction and stop movement.

[0062] The present invention is not limited to the above embodiments. Anyone should know that structural changes made under the inspiration of the present invention, as long as they have the same or similar technical solutions as the present invention, all fall within the protection scope of the present invention.

[0063] The technologies, shapes, and structures not described in detail in the present invention are all well-known technologies.

The comprehensive operation vehicle for disassembly and assembly of in-station tracks of medium and low speed maglev transportation according to claim 1, characterized in that, The rail transport trolley includes a driving and traveling mechanism, a limit bracket, an F-shaped guide rail horizontal bracket and a frame. The driving and traveling mechanism is installed inside the drive wheel. The frame is installed on the drive wheel. The upper part of the frame is provided with a limit bracket and an F-shaped guide rail horizontal bracket for placing the new F-shaped guide rail. Both the driving and traveling mechanism and the traveling drive mechanism of the suspension crane are internally provided with servo motors with braking functions. A transmission mechanism is arranged between the output shaft of the servo motor and the drive wheel described above.

6. The integrated operation vehicle for disassembly and assembly of the inner track in medium and low speed maglev transportation station according to claim 5, characterized in that The drive wheels of the traveling drive mechanism of the suspension crane are arranged on the aluminum induction plate of the old F-shaped guide rail. The drive wheels of the driving and traveling mechanism are arranged on the running surface of the old F-shaped guide rail. Guide mechanisms are arranged on both sides of the suspension trolley. The guide mechanisms cooperate with the outer magnetic pole sides of the old F-shaped guide rail for the guide mechanisms to travel on the running surface of the track beam.

7. The working method of the comprehensive operation vehicle for disassembly and assembly of the inner track in the medium and low speed maglev transportation station according to any one of claims 1-6, characterized in that, It includes the following steps: 1) Position the suspension trolley. Operate the electric control system box, start the horizontal V-shaped telescopic drive motor and the tilting sliding part drive motor to drive the special-shaped moving support arm to move to a safe position, so that the extended limit plate is not in contact with the track beam and no longer "clamps" the track beam; 2) Start the suspension wheel lifting system to place the traveling drive mechanism of the suspension crane on the old F-shaped guide rail, lift the suspension trolley to a certain height, check the heights of the 4 horizontal extension support frames, so that their lower surfaces no longer fit the upper surface of the track beam, and the suspension trolley is lifted upward and has a safety distance of more than 10-20 mm; 3) Start the horizontal telescopic drive motor to make the horizontal extension support frame move laterally outward to both sides of the track beam along the suspension crane accommodation support groove until the end of the horizontal extension support frame moves to a position 10-20 mm away from both sides of the track beam; 4) At this time, the suspension trolley is in a "traveling" state. Start the traveling drive mechanism of the suspension crane to drive the suspension trolley forward. After driving the suspension trolley to the operation area where the old F-shaped guide rail needs to be replaced, operate the electric control system box of the suspension trolley in the reverse steps after completing the above experimental steps. Start the horizontal telescopic drive motor in sequence, start the suspension wheel lifting system to make the suspension trolley in the "temporarily stop and fix" state, and then the rail transport trolley transports the new F-shaped guide rail 5 to this suspension trolley; 5) At this time, adjust the positions of the monorail crane and the hook through the electric control system box. For the single-sided replacement of the new F-shaped guide rails on both sides of the same track panel, tie the old F-shaped guide rails to be disassembled well with a lifting belt, remove the connecting bolts between the old F-shaped guide rails and the sleeper H-beams, start the hoisting mechanism, and lift the old F-shaped guide rails onto the rail transport trolley; then adjust the positions of the monorail crane and the hook through the electric control system box to install the new F-shaped guide rails at the position of the above-mentioned old F-shaped guide rails and tighten the connecting bolts; repeat the above actions to complete the replacement of the old F-shaped guide rails on the other side of the track panel. During the installation process, the connection between the new F-shaped guide rails and the existing sleepers, the gauge adjustment, and the torque should be adjusted according to the technical parameters of the track panel; 6) According to the operation requirements, the rail transport trolley operates through the electric control system box to exit this operation area and drive to the next operation area or stop for operation; The suspension trolley starts the "walking" state through the operation of the electric control system box, drives to the next operation area or stops operating. The actions of the suspension trolley and the rail transport trolley cooperate with each other to form a cyclic action mode. And so on, the comprehensive operation of track disassembly and assembly in the station can be completed.
