Description

Technical Field

[0001] This application belongs to the field of mechanical equipment technology, specifically relating to a prefabricated maintenance device that integrates civil engineering and electromechanical systems. Background Technology

[0002] Prefabricated maintenance equipment provides a platform for workers to walk and operate during the maintenance of vehicles or construction machinery awaiting repair. Prefabricated maintenance equipment typically includes a platform, moving equipment, and protective devices. When inspecting equipment, various locations such as the sides, top, and bottom need to be checked. To facilitate inspection of different locations, moving equipment is usually added to the prefabricated maintenance equipment, allowing it to move forward and backward and up and down. Workers can use this equipment to adjust the prefabricated maintenance equipment to a suitable position during operations.

[0003] However, there are risks of personnel falling and tools falling when maintenance personnel work on prefabricated maintenance equipment. Accidents are more likely to occur, especially when the prefabricated maintenance equipment is moved or when personnel are going up or down. The existing protective devices equipped on prefabricated maintenance equipment mainly rely on maintenance personnel to manually open and close them. If maintenance personnel are negligent and fail to take safety measures, accidents cannot be effectively prevented. Summary of the Invention

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the fixed scope of the present invention.

[0032] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0033] This embodiment discloses a prefabricated maintenance device integrating civil engineering and electromechanical systems, including a platform 1, a moving mechanism 2, a protective mechanism 3, and a triggering mechanism 4. The platform 1 is mounted on the moving mechanism 2, and the protective mechanism 3 is movably mounted on the platform 1. The protective mechanism 3 has a working state and a non-working state. The triggering mechanism 4 is connected to the moving mechanism 2 and the protective mechanism 3 respectively. When the moving mechanism 2 is started, it can drive the triggering mechanism 4 to drive the protective mechanism 3 into the working state.

[0034] like Figure 1As shown, the prefabricated maintenance device integrating civil engineering and electromechanical systems in this embodiment mainly includes a platform 1, a moving mechanism 2, a protective mechanism 3, and a triggering mechanism 4. The platform 1 provides space for maintenance personnel to stand and operate. The moving mechanism 2 is used to move the maintenance device laterally within the maintenance trench and adjust its vertical height. During operation, maintenance personnel stand on the platform 1, which is typically at a certain height above the ground, posing a risk of falls and tool drops. Protective devices of a certain height are installed around the edge of the platform 1 to protect the maintenance personnel. Depending on the maintenance location, the maintenance personnel can freely adjust the position of the maintenance device, allowing them to maintain a comfortable posture while performing maintenance work on the platform 1. This eliminates the need for repeated standing or squatting postures during inspections, improving comfort and reducing fatigue.

[0035] The protective mechanism 3 is typically a closed fence with openable doors or other devices at the personnel access points. To ensure on-site safety, the protective mechanism 3 must provide reliable protection when maintenance personnel ascend platform 1 to begin maintenance work, especially when the maintenance equipment is moving. The risk of falling is higher due to the speed of movement and the swaying of the equipment, so the protective mechanism 3 must be in a closed state. However, manual operation of the doors can easily lead to safety hazards caused by human negligence. At the start and end of maintenance work, maintenance personnel must ascend platform 1 from the ground, close the door after they finish, and open the door again to return to the ground after completing the maintenance. If the safety operating procedures are not strictly followed, it is easy to forget to close the door. In actual production, situations often arise where the maintenance equipment is already in motion but the protective mechanism is not closed, which can easily lead to accidents such as falls from heights.

[0036] In this embodiment, a triggering mechanism 4 is added to the maintenance device. The triggering mechanism 4 is connected to both the moving mechanism 2 and the protective mechanism 3. The movement of the moving mechanism 2 is transmitted in real-time to the triggering mechanism 4 via a transmission mechanism such as a piston 402, mechanical linkage, and gear 4064, thereby triggering the automatic opening of the protective mechanism 3. The triggering mechanism 4 controls the switching between the working and non-working states of the protective mechanism 3 through mechanical transmission between the moving mechanism 2 and the protective mechanism 3. When the moving mechanism 2 is open and the maintenance device begins to move along the maintenance trench, the triggering mechanism 4 automatically controls the protective mechanism 3 to close, protecting the personal safety of personnel on the maintenance device and reducing safety risks caused by the subjective factors of maintenance personnel.

[0037] In practical application, the maintenance device is first assembled and placed inside the maintenance trench. After assembly, when bottom maintenance is required on vehicles or construction machinery parked at the top of the trench, the operator first climbs onto platform 1, and then controls the maintenance device to move to the designated position via the moving mechanism 2. During the movement, the protective mechanism 3 simultaneously activates, providing protection for the maintenance personnel on platform 1. After completing one maintenance point, the maintenance personnel continue to control the maintenance device to move to the next maintenance point via the moving mechanism 2, avoiding fatigue caused by prolonged walking maintenance, which affects work efficiency and quality. Furthermore, the maintenance personnel can adjust the maintenance height as needed while moving within the trench, eliminating the need for repeated standing or squatting for inspections, thus improving worker comfort and maintenance efficiency. Overall, the device offers excellent performance. When the mobile mechanism 2 is activated and moves the maintenance device inside the trench, it will trigger the protective mechanism 3 to be activated, thereby intercepting and protecting the maintenance personnel on the platform 1. This prevents the maintenance personnel from accidentally stepping into a hole and falling while looking up to perform maintenance on the platform 1, and also prevents the maintenance tools placed on the platform 1 from sliding into the maintenance trench, thus ensuring safety during mobile maintenance.

[0038] In some optional embodiments, the triggering mechanism 4 includes a fixed frame 401, a piston 402, an air collecting cylinder 403, and an air guide pipe 404. The fixed frame 401 is mounted on the moving mechanism 2, and the air collecting cylinder 403 is mounted on the fixed frame 401. One end of the cylinder is connected to the air guide pipe 404, and the other end is slidably equipped with the piston 402. The air guide pipe 404 is connected to the protective mechanism 3, and the piston 402 is connected to the moving mechanism 2. When the moving mechanism 2 is activated, the piston 402 reciprocates, and the gas in the air collecting cylinder 403 enters the protective mechanism 3 through the air guide pipe 404, driving the protective mechanism 3 into the working state.

[0039] like Figure 4 and Figure 5 As shown, the triggering mechanism 4 includes a fixed frame 401, a piston 402, an air collecting cylinder 403, and an air guide pipe 404. The piston 402 enables the interlocking transmission between the moving mechanism 2 and the protective mechanism 3. The fixed frame 401 is used to fix the air collecting cylinder 403 to the moving mechanism 2. The air collecting cylinder 403 is a hollow cylinder, with its top connected to the air guide pipe 404 and its bottom equipped with a piston 402 that slides along the inner wall of the cylinder. The piston 402 is connected to the moving mechanism 2 and can move back and forth within the air collecting cylinder 403 as the device moves, discharging the gas in the air collecting cylinder 403 into the protective mechanism 3 through the air guide pipe 404 to trigger the working state of the protective mechanism 3.

[0040] Furthermore, the gas collecting cylinder 403 and the gas guiding pipe 404 are connected by a one-way exhaust valve 4032, allowing gas to flow only from the gas collecting cylinder 403 into the gas guiding pipe 404. The gas collecting cylinder 403 is also equipped with a one-way inlet valve 4031 that connects to the outside, allowing gas to flow only from the outside into the gas collecting cylinder 403, thus achieving unidirectional gas flow within the gas collecting cylinder 403 and the gas guiding pipe 404. The gas guiding pipe 404 can be arranged around the edge of the platform 1 to evenly guide the gas squeezed into the gas guiding pipe 404 from different positions into the protective mechanism 3.

[0041] In some alternative embodiments, the moving mechanism 2 includes a drive wheel 201, a mounting member 202, and a first switch 203. The drive wheel 201 is symmetrically arranged on both sides of the mounting member 202 and connected to the piston 402. The fixing frame 401 is arranged on the mounting member 202 close to the drive wheel 201. The platform 1 is arranged on the mounting member 202 and has a first surface 101 and a second surface 102 that are opposite to each other. The first surface 101 is away from the mounting member 202. The first switch 203 is arranged on the first surface 101 and is electrically connected to the drive wheel 201.

[0042] like Figure 1 - Figure 3 As shown, in this embodiment, the moving mechanism 2 controls the maintenance device to move on the ground via an electrically driven drive wheel 201. At least one drive wheel 201 is connected to a piston 402 in the triggering mechanism 4. When the drive wheel 201 rotates, it drives the piston 402 to move, thereby transmitting the movement of the maintenance device to the triggering mechanism 4 in real time, which in turn triggers the activation of the protective mechanism 3. The first surface 101 is the standing surface of the platform 1, and a first switch 203 for activating the drive wheel 201 is provided on the first surface 101. When maintenance personnel begin to inspect the bottom of vehicles or construction machinery, they can activate the first switch 203 on the platform 1 to control the drive wheel 201 to start, thereby driving the maintenance device and the maintenance personnel standing on the platform 1 to move laterally inside the maintenance trench. This avoids fatigue caused by long-term walking maintenance, which could lead to missed maintenance tasks, and makes the overall maintenance more convenient.

[0043] For example, such as Figure 3 As shown, the first switch 203 can be a push-button switch, which can be activated by foot by maintenance personnel. This facilitates control without requiring bending over or squatting to turn on the switch, and does not occupy the limited space on the platform 1. In some embodiments, the first switch 203 can also be an operating lever protruding a certain height from the first surface 101, or a remote control connected via wireless equipment. This application embodiment does not specifically limit the structure of the first switch 203 in the moving mechanism 2 described above.

[0044] In addition, in some optional embodiments, the moving mechanism 2 further includes a limiting guide wheel 204, which is symmetrically arranged on both sides of the mounting member 202. The maintenance device is arranged in the maintenance trench, the drive wheel 201 is used to move on the bottom ground of the maintenance trench, and the limiting guide wheel 204 is used to roll contact with the side wall of the maintenance trench.

[0045] like Figure 3 As shown, the limiting guide wheel 204 protrudes from the surface of the mounting part 202. When assembled with the maintenance trench, the limiting guide wheel 204 can contact the side wall of the maintenance trench and slide along the side wall. This limits the lateral movement angle of the entire device, acts as a buffer when the maintenance device moves, ensures the overall movement stability, and has a good overall performance.

[0046] In some alternative embodiments, the piston 402 includes a limiting post 4021, a sliding groove 4022, and a limiting rod 4023. One end of the limiting rod 4023 is connected to the air collecting cylinder 403, and the other end is connected to the sliding groove 4022. The length of the sliding groove 4022 is at least the outer diameter of the drive wheel 201. The projection of the limiting rod 4023 on the drive wheel 201 passes through the center of the drive wheel 201. The limiting post 4021 is disposed on the drive wheel 201 and is engaged in the sliding groove 4022. The limiting post 4021 can slide in the sliding groove 4022.

[0047] like Figure 5As shown, the piston 402 includes a limiting rod 4023 that extends into and slides within the gas collecting cylinder 403, a limiting post 4021 fixed to the drive wheel 201, and a sliding groove 4022 connecting the limiting rod 4023 and the limiting post 4021. One end of the limiting post 4021 is fixed to the outer edge of the drive wheel 201 and can rotate synchronously with the drive wheel 201. The other end is engaged in the sliding groove 4022 and can slide relative to the sliding groove 4022. The length of the sliding groove 4022 is at least the outer diameter of the drive wheel 201, allowing the limiting block to reciprocate within the sliding groove 4022. The sliding groove 4022 is fixedly connected to the limiting rod 4023. When the drive wheel 201 starts to rotate, the limiting post 4021 on the drive wheel 201 rotates synchronously and makes a circular motion relative to other components of the maintenance device. The circular motion of the limiting post 4021 can be decomposed into two motions in the horizontal and vertical directions. In the horizontal direction, it slides repeatedly along the slide groove 4022, and in the vertical direction, it moves up and down. At the same time, it drives the slide groove 4022 connected to the limiting post 4021 to move synchronously. The limiting rod 4023, which is fixedly connected to the slide groove 4022, also makes a reciprocating motion in the vertical direction. The limiting rod 4023, the limiting post 4021, and the slide groove 4022 together form the piston 402 structure. As the drive wheel 201 rotates, it continuously squeezes the gas in the gas collecting cylinder 403 into the air guide pipe 404. The gas is drawn into the interior of the gas collecting cylinder 403 through the one-way inlet valve 4031, and then squeezed into the interior of the air guide pipe 404 through the one-way exhaust valve 4032.

[0048] In some optional embodiments, the moving mechanism 2 further includes a support frame 205, a driving member 206, and a second switch 207. The support frame 205 is symmetrically arranged between the platform 1 and the mounting member 202. The support frame 205 includes a fixed rod 2051, a movable rod 2052, a fixed shaft 2053, a limiting seat 2054, and a roller rod 2055. The two sets of fixed rods 2051 and movable rods 2052 are rotatably connected at both ends of the fixed shaft 2053. The fixed rod 2051 is rotatably connected to the mounting member 202 through the limiting seat 2054. The two ends of the roller rod 2055 are rotatably connected to the two movable rods 2052 respectively. One end of the driving member 206 is connected to the fixed shaft 2053, and the other end is connected to the roller rod 2055. The second switch 207 is disposed on the first surface 101 and is electrically connected to the driving member 206.

[0049] like Figure 3As shown, the two ends of the fixed rod 2051 are rotatably fixed to the platform 1 and the mounting component 202, respectively. One end of the movable rod 2052 is fixed to the platform 1, and the other end is connected to the roller rod 2055. The fixed rod 2051 and the movable rod 2052 are centrally connected to the fixed shaft 2053 to form a telescopic X-shaped frame. When the device moves laterally to enable maintenance personnel to begin maintenance on the bottom of vehicles or construction machinery, the second switch 207 can be stepped on to control the extension and retraction of the drive component 206, thereby driving the roller rod 2055 to roll, causing the support frame 205 to deform, thus adjusting the lifting height of the platform 1. This allows maintenance personnel to freely adjust the maintenance height as needed when moving and maintaining in the trench, eliminating the need for repeated standing or squatting for inspection, improving the comfort of maintenance personnel, increasing maintenance efficiency, and resulting in good overall performance.

[0050] In some alternative embodiments, the protective mechanism 3 includes a hollow column 301, a protective net 302, a scroll 303, and an airbag 304. The hollow column 301 is vertically arranged at the top of the platform 1, and an airbag 304 is provided at one end near the moving mechanism 2. The bottom of the airbag 304 is connected to the air duct 404. A connecting groove 3011 is provided on the hollow column 301 along its length. A connecting frame 3021 is provided at the top of the protective net 302. The two ends of the connecting frame 3021 are inserted into the connecting groove 3011 and overlap the airbag 304. The bottom of the protective net 302 is wound around the scroll 303. The scroll 303 is located at the edge of the platform 1, and a reset torsion spring 3031 is provided at both ends of the scroll 303.

[0051] like Figure 4 and Figure 6As shown, hollow columns 301 are installed at the four corners of platform 1 to support the protective net 302. The hollow columns 301 and the protective net 302 form a closed space of a certain height around the edge of platform 1, providing protection for maintenance personnel working on platform 1. The hollow columns 301 are hollow inside, and an airbag 304 is provided at the bottom. The airbag 304 is connected to the air guide pipe 404 in the triggering mechanism 4. After the airbag 304 is inflated through the air guide pipe 404, it expands until it expands to the designated position at the top of the hollow column 301. A connecting groove 3011 is longitudinally provided through the column body of the hollow column 301 for installing the protective net 302. The connecting bracket 3021 at the top of the protective net 302 protrudes at both ends and is engaged in the connecting groove 3011. The two ends overlap the top of the airbag 304 and can slide up and down along the connecting groove 3011 as the airbag 304 is inflated and deflated. When the airbag 304 inflates, it pushes the connecting bracket 3021, which is engaged in the connecting groove 3011, to rise, causing the protective net 302 to rise. When the airbag 304 deflates and contracts, the protective net 302 falls. The bottom of the protective net 302 is wound in the roller 303, and the end of the roller 303 is equipped with a return spring, which keeps the roller 303 in an inwardly tightened state, applying a downward pulling force to the connecting bracket 3021. When the airbag 304 contracts, the connecting bracket moves downward under the traction force of the roller 303, thereby winding the protective net 302 back into the roller 303, realizing the automatic adjustment of the height of the protective net 302.

[0052] In practical applications, the protective net 302 can be a fully movable type, with each side of the net 302 automatically rising and falling under the control of the triggering mechanism 4. Alternatively, it can be partially movable, with only the side of the net 302 accessible to personnel movable, while the remaining nets 302 are fixed to the hollow columns 301. As shown in the figure, railings 305 are fixed between the hollow columns 301 on both sides adjacent to the sidewall of the maintenance trench, while the other two sides are slidable and liftable protective nets 302, facilitating access for maintenance personnel. The movable and lifting parts of the protective net 302 should be made of deformable flexible material to facilitate winding into the roller 303.

[0053] Furthermore, such as Figure 6 As shown, on the side of platform 1 near the protective net 302, a limiting groove 103 is provided between two adjacent hollow columns 301 at the position where the protective net 302 is installed, penetrating through platform 1. A roller 303 is installed at the bottom of platform 1 along the edge of the groove. After the protective net 302 is pulled out from the roller 303, it passes through the limiting groove 103 and is installed in the hollow column 301. The two ends of the connecting frame 3021 extend into the hollow column 301 through the connecting groove 3011 and are positioned above the airbag 304, completing the installation of the protective net 302. The protective net 302 is set in the limiting groove 103, and the outer platform 1 can provide a certain degree of protection for the flexible protective net 302, preventing the protective net 302 from being damaged by scratching with sharp objects during use.

[0054] When maintenance personnel stand on platform 1 and turn on the first switch 203, the drive wheel 201 drives the maintenance device to move as a whole for maintenance. The drive wheel 201 drives the limit column 4021 to rotate synchronously. The slide 4022 and the limit rod 4023 connected to the slide 4022 move up and down under the action of the limit column 4021. As the drive wheel 201 rotates, it continuously squeezes the gas in the gas collecting cylinder 403 into the air guide pipe 404. Gas is then introduced into the air bladders 304 inside the bottom of multiple hollow columns 301, causing the air bladders 304 inside the hollow columns 301 to expand and rise along the inner wall of the hollow columns 301. This causes the connecting frame 3021, which is slidably engaged between the hollow columns 301, to begin to rise along the connecting groove 3011. The rising of the connecting frame 3021 drives the roller 303 to rotate, thereby automatically pulling up the protective net 302. This causes the protective nets 302 on both sides of the platform 1 to be automatically pulled up simultaneously, thus intercepting and protecting the maintenance personnel on the platform 1. This prevents maintenance personnel from accidentally stepping into a hole and falling while moving and inspecting on the platform 1, and also prevents maintenance tools placed on the platform 1 from slipping into the maintenance trench, ensuring safety during mobile maintenance. At the same time, whenever the device is moved, the protective net 302 will be automatically pulled up simultaneously to prevent maintenance personnel from forgetting to move it. Overall, the safety and convenience are high.

[0055] In some optional embodiments, the triggering mechanism 4 further includes a cavity column 4051, a piston rod 4052, a first spring 4053, and an exhaust port 4054. The cavity column 4051 protrudes from the surface of the air guide tube 404, with one end communicating with the air guide tube 404 and the other end slidably provided with the piston rod 4052. The piston rod 4052 covers the through hole through which the cavity column 4051 communicates with the air guide tube 404. The first spring 4053 connects the piston rod 4052 and the cavity column 4051. An exhaust port 4054 is provided through the edge of the cavity column 4051 away from the air guide tube 404 for discharging gas.

[0056] When the airbag 304 inflates to a certain extent, the connecting frame 3021 pulls the protective net 302 to the designated position. At this point, due to the seal at the top of the hollow column 301, the airbag 304 will no longer inflate and drive the connecting frame 3021 to continue rising. However, as long as the maintenance device remains in a moving state, the piston 402 will continuously reciprocate, continuously venting air into the airbag 304. Therefore, a pressure relief mechanism 405 needs to be installed in the air duct 404. A pressure relief mechanism 405 protruding from the surface of the air duct 404 is installed on the air duct 404, such as... Figure 7As shown, the structure specifically includes a cavity column 4051, a piston rod 4052, a first spring 4053, and an exhaust port 4054. The bottom of the cavity column 4051 is connected to the air guide pipe 404. The piston rod 4052 is slidably disposed inside the cavity column 4051 and is connected to the top of the cavity column 4051 via the first spring 4053. An exhaust port 4054, communicating with the outside, is opened on the side wall of the cavity column 4051 away from the air guide pipe 404. When the first spring 4053 is in a compressed state, it compresses the piston rod 4052, covering the through hole connecting the cavity column 4051 and the air guide pipe 404. At this time, the gas squeezed into the air guide pipe 404 by the air collecting cylinder 403 is discharged into the air bladder 304 of the protective mechanism 3 along the air guide pipe 404. When the airbag 304 inflates to the top of the hollow column 301, the airbag 304 stops inflating. If the maintenance device continues to move, the piston 402 continues to pump air into the air pipe 404 and the airbag 304. The pressure in the gas channel continues to increase. When the pressure of the gas acting on the piston rod 4052 is greater than the elastic force of the first spring 4053, the piston rod 4052 is pushed open by the gas, and the first spring 4053 is compressed and deformed. When the piston rod 4052 is raised to the exhaust port 4054, the exhaust port 4054 is connected to the gas channel, thereby automatically discharging the gas squeezed out inside the subsequent gas collecting cylinder 403, thus ensuring the operational stability of the device and playing a certain role in automatic pressure relief.

[0057] Furthermore, the aforementioned device can also be used to control the protective mechanism 3 to disengage and return to a non-working state when maintenance personnel need to leave the maintenance equipment and return to the ground. When it is necessary to open the protective net 302, simply lift the piston rod 4052 to connect the exhaust port 4054 and the air guide pipe 404. The protective net 302 will then retract into the reel 303 under the traction force of the return torsion spring 3031. During the descent, the connecting frame 3021 continuously compresses the airbag 304, and the gas in the airbag 304 is discharged through the exhaust port 4054 until the protective net 302 is completely lowered below the platform 1.

[0058] In some alternative embodiments, the triggering mechanism 4 further includes a toolbox 4061, a pressure rod 4063, a gear 4064, a first rack 4065, and a second rack 4066. The toolbox 4061 is mounted on the protective mechanism 3. A slidable placement plate 4062 is provided at the bottom of the toolbox 4061. A second spring connects the placement plate 4062 and the bottom of the toolbox 4061. One end of the pressure rod 4063 extends into the toolbox 4061 and is connected to the placement plate 4062. The other end is connected to the first rack 4065. The first rack 4065 and the second rack 4066 mesh with the gear 4064. The second rack 4066 is connected to the piston rod 4052.

[0059] like Figure 9 and Figure 10As shown, the toolbox 4061 can be installed on top of the hollow column 301. Commonly used maintenance tools are kept in the toolbox 4061 for easy access by maintenance personnel. The bottom of the toolbox 4061 has a sliding plate 4062 that can slide along the inner wall of the toolbox 4061. This plate is connected to the bottom plate of the toolbox 4061 by a second spring. When the toolbox 4061 is not in use, the spring force of the second spring maintains a certain gap between the plate 4062 and the bottom plate of the toolbox 4061. A pressure rod 4063 is connected to the bottom of the plate 4062. The pressure rod 4063 slidably passes through the bottom plate of the toolbox 4061 and extends downwards. The other end is connected to a first rack 4065. The first rack 4065 and the second rack 4066 mesh with a gear 4064. Under the action of the gear 4064, the first rack 4065 and the second rack 4066 move in opposite directions. The bottom of the second rack 4066 is connected to the piston rod 4052 that passes through the cavity column 4051. When a heavy object is placed in the toolbox 4061, the placement plate 4062 is pressed down, and the pressure rod 4063 and the first rack 4065 on the pressure rod 4063 move downwards. The second rack 4066 and the piston rod 4052 move upwards, causing the exhaust port 4054 in the cavity column 4051 to open, and the gas in the airbag 304 is discharged through the exhaust port 4054.

[0060] Understandably, if the maintenance device is stationary at this time, the gas collecting cylinder 403 will no longer squeeze gas into the air guide pipe 404 and the air bag 304. The air bag 304 will then contract as the internal gas is expelled, the protective net 302 will automatically descend, and the protective mechanism 3 will enter a non-working state, allowing maintenance personnel to move up and down platform 1. If the maintenance device is still moving, the piston 402 will continuously squeeze gas from the gas collecting cylinder 403 into the air bag 304, supporting the protective net 302 in the designated position, and the protective mechanism 3 will remain in a working state. Only when the moving mechanism 2 is closed and the maintenance device is stationary can maintenance personnel open the protective mechanism 3 by placing maintenance tools into the toolbox 4061. This prevents maintenance personnel from accidentally opening the protective mechanism 3 and falling during maintenance by carelessly placing tools around, further ensuring the safety of maintenance personnel.

[0061] After maintenance personnel finish their work, the control drive wheel 201 drives the maintenance device to the exit of the maintenance trench. The maintenance personnel place the maintenance tools into the toolbox 4061. Under the gravity of the maintenance tools, the placement plate 4062 in the toolbox 4061 descends, and the pressure rod 4063 and the first rack 4065 descend synchronously. When the first rack 4065 descends, it drives the gear 4064 meshing on one side to rotate. The rotation of the gear 4064 drives the second rack 4066 meshing on the other side to rise synchronously, thereby driving the piston rod 4052 to rise synchronously. This allows the airflow channel formed by the air pipe 404 and the airbag 304 to connect with the outside through the exhaust port 4054 in the cavity column 4051, and the air begins to be released. At the same time, with the rebound of the return torsion spring 3031 on one side of the roller 303, the side protective net 302 automatically descends, making it easier for the maintenance personnel to walk out of the maintenance device. The mechanism requires maintenance personnel to place maintenance tools into toolbox 4061 before it can be activated. This is to prevent maintenance personnel from forgetting to place maintenance tools into toolbox 4061, which could result in the loss of maintenance tools and affect subsequent shifts of maintenance personnel from performing maintenance operations.

[0062] Furthermore, since the pressure rod 4063 is a slender rod with weak bending resistance, it is prone to bending and damage under repeated stress. Therefore, an auxiliary frame 4067 can be fixedly installed on the outside of the toolbox 4061, through which the pressure rod 4063 passes. The auxiliary frame 4067 provides fixation and protection for the pressure rod 4063.

[0063] In addition, in some optional embodiments, the triggering mechanism 4 also includes an exhaust pipe 407 and a jet head 408. The exhaust pipe 407 is disposed along the edge of the platform 1 and is connected to the output end of the exhaust port 4054. A plurality of jet heads 408 are disposed on the exhaust pipe 407 along the length direction, and the output ends of the jet heads 408 are all facing the first surface 101.

[0064] like Figure 11 As shown, the exhaust port 4054 is connected to the exhaust pipe 407, which is arranged around the edge of the platform 1 and has multiple jet nozzles 408 facing the first surface 101 of the platform 1. Gas from the air collection cylinder 403 and the airbag 304 first enters the air guide pipe 404, then enters the exhaust pipe 407 from the exhaust port 4054, and finally exits through the jet nozzles 408. The exited gas is blown towards the first surface 101, which can remove dust from the platform 1.

[0065] When maintenance personnel complete the maintenance and remove the protective mechanism 3, the gas inside the airbag 304 of the protective net 302 is rapidly discharged. In conjunction with the conduction setting of the exhaust port 4054 and the exhaust pipe 407, the discharged gas enters the interior of the exhaust pipe 407 and is then orderly guided into the interior of several jet heads 408. Finally, the discharged gas is blown onto the surface of the platform 1, thereby performing a rotating air blowing dust removal operation on the first surface 101 of the platform 1, ensuring cleanliness and achieving good overall performance.

[0066] This application discloses a prefabricated maintenance device integrating civil engineering and electromechanical systems, including a platform, a moving mechanism, a protective mechanism, and a triggering mechanism. The platform is mounted on the moving mechanism, and the protective mechanism is movably mounted on the platform. The protective mechanism has a working state and a non-working state. The triggering mechanism is connected to both the moving mechanism and the protective mechanism. When the moving mechanism is activated, it can drive the protective mechanism to enter the working state. The addition of the triggering mechanism to the maintenance device controls the switching between the working and non-working states of the protective mechanism through mechanical transmission between the moving mechanism and the protective mechanism. When the moving mechanism is activated and the maintenance device begins to move along the maintenance trench, the triggering mechanism automatically controls the closing of the protective mechanism, protecting the personal safety of personnel on the maintenance device. This adds automated safety assurance to maintenance work and reduces safety hazards caused by human factors.
