Detailed Description of the Embodiments

[0054] Exemplary embodiments will be described in detail herein, and examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application.

It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application described herein, for example, can be implemented in an order other than those illustrated or described herein.

[0056] In the embodiments of the present application, words such as "exemplarily" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplarily" or "for example" in the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplarily" or "for example" is intended to present relevant concepts in a specific manner.

[0057] In industries such as power and communication, cable trenches, as important facilities for laying underground cables, are of great significance for ensuring the safe and stable operation of cables. Cable trenches are usually built of concrete or masonry, with a certain depth and width to facilitate the installation and maintenance of cables. In cable trenches with a large number of cables laid, cable brackets for placing cables are provided on one or both side walls of the cable trench. An inspection passage is also left along the extending direction of the cable trench, and within the inspection passage, workers can inspect the cables on the cable brackets in the trench.

[0058] In the related art, workers usually need to first pry open the cable trench cover plate with tools such as shovels and crowbars, and then enter the cable trench for operation through a ladder. The process of prying open the cover plate is time-consuming and laborious, and it is easy to damage the cover plate, increasing the maintenance cost. Especially when continuously operating on a long-section cable trench, workers need to repeatedly pry open multiple cover plates, which is particularly cumbersome and greatly reduces the work efficiency. When workers enter the cable trench for operation through a ladder, during the long-term continuous operation process, the placement and movement of the ladder may also become a safety hazard. Especially in bad weather conditions such as rainy days and snowy days, the ladder is prone to slipping or instability, further increasing the operation risk.

[0059] In summary, when continuously operating on a long-section cable trench, the process of opening the cover plate and entering the cable trench is cumbersome and time-consuming, and there are certain operation risks, resulting in low operation efficiency of workers.

[0060] Based on this, the cable trench mobile maintenance device provided in this application aims to solve the above technical problems in the prior art.

[0061] The technical solution of this application and how the technical solution of this application solves the above technical problems will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below with reference to the drawings.

[0062] Please refer to Figure 1 and Figure 2 The cable trench mobile maintenance device provided in the embodiments of this application includes a vehicle frame 100, a maintenance operation component 200, a cover plate moving component 300, and a walking driving component 400.

[0063] The vehicle frame 100 is provided with an operation opening 110. The maintenance operation component 200 is arranged on the vehicle frame 100. The maintenance operation component 200 includes an operation chamber 210, and the operation chamber 210 is arranged at the operation opening 110 in a liftable manner. The cover plate moving component 300 includes a suction component 310 and a moving component 320. The moving component 320 is arranged on the vehicle frame 100. The suction component 310 is connected to the moving component 320. The suction component 310 is used to lift and lower the cover plate above the cable trench. The moving component 320 is configured to at least drive the suction component 310 to move up and down relative to the vehicle frame 100. The walking driving component 400 is used to drive the vehicle frame 100 to move.

[0064] The frame 100 is the support structure of the entire device, and the maintenance operation assembly 200, the cover plate moving assembly 300, and the traveling drive assembly 400 are all installed on the frame 100. An operation opening 110 is provided on the frame 100, and the width of the operation opening 110 corresponds to the width of the cable trench. The frame 100 can be a planar frame structure, and the frame structure forms an opening as the operation opening 110. The operation opening 110 is used to be oppositely arranged with the inspection opening, so that the operation chamber 210 can move downward and enter the inspection opening.

[0065] The maintenance operation assembly 200 is installed on the frame 100 and is used to lower the staff into the cable trench. Its functional components include the operation chamber 210. The operation chamber 210 provides a liftable operation platform for the staff, facilitating the staff to enter or leave the cable trench, so that the staff does not have to move up and down in the cable trench through a ladder. At the same time, since the maintenance operation assembly 200 is installed on the frame 100, the operation chamber 210 can move along with the frame 100. That is to say, the staff can move in the cable trench through the operation chamber 210, and thus can continuously and safely transfer in the cable trench along with the movement of the frame 100.

[0066] The operation chamber 210 can be selected as a box structure. A working window is provided on the side of the box structure. The staff can stand in the box structure. After the box structure transports the staff to the cable trench through the inspection opening, the staff can perform maintenance work through the working window.

[0067] On the frame 100, a track can be selected to be arranged vertically. The top of the operation chamber 210 is slidably connected to the track. A driving member is connected between the operation chamber 210 and the track. The driving member can be selected as a motor. The motor is connected to the frame 100. A vertical rack is provided on the side of the operation chamber 210. A gear is provided at the output end of the motor. The gear is meshed with the rack. When the motor drives the gear to rotate, the operation chamber 210 can be driven to rise or fall along the track. Since the top of the operation chamber 210 is connected to the track and the bottom end of the track is at the operation opening 110, when the top end of the operation chamber 210 slides to the bottom end of the track, the operation chamber 210 can be located below the frame 100 through the operation opening 110.

[0068] Of course, it can also be selected to set a bracket on the side of the frame 100 facing away from the ground. A pulley block and a sling are provided on the bracket. The sling is connected to the operation chamber 210. The lifting of the operation chamber 210 can be controlled by the movement of the sling.

[0069] During the maintenance process of the cables in the cable trench, due to the complex environment in the cable trench, the maintenance operation is difficult. The operation bin 210 can provide a standing platform for the staff, so that the staff do not have to be completely in the operation environment in the cable trench, which is beneficial to reducing the accidental contact of the staff with live cables or other components, and reducing the situations such as slipping and falling of the staff due to the wet and slippery environment in the cable trench. Especially when the cable trench is relatively deep, it can provide more safety protection for the staff.

[0070] The cover plate moving assembly 300 is used to automatically lift and lower the cable trench cover plate. The adsorbing component 310 lifts the cover plate by adsorption, such as a vacuum suction cup 312 or a magnet component. The moving component 320 can be selected as a telescopic cylinder, a screw drive mechanism, or an orbital translation mechanism to drive the adsorbing component 310 to move, so that the moving component 320 can drive the adsorbing component 310 to move in the vertical direction. That is, when the cover plate needs to be opened, the moving component 320 drives the adsorbing component 310 to move above the cover plate. After the adsorbing component 310 moves downward and fits with the cover plate, the adsorption function is activated to lift the cover plate. Then, the moving component 320 drives the adsorbing component 310 to move upward to make the cover plate out of the maintenance opening. The walking drive assembly 400 drives the vehicle frame 100 to move to the position where the operation opening 110 is opposite to the operation bin 210, so that the cover plate can be moved to the side of the maintenance opening.

[0071] Of course, the adsorbing component 310 can also be selected as a three-axis moving mechanism, or includes a first frame and a second frame. The first frame is slidably connected to the vehicle frame 100 in the horizontal direction, and the second frame is slidably connected to the first frame in the vertical direction. The adsorbing component 310 is installed on the second frame. The adsorbing component 310 completes the lifting operation as the second frame slides relative to the first frame in the vertical direction. The first frame slides relative to the vehicle frame 100 in the horizontal direction, so that the adsorbing component 310 can move in the horizontal direction, and the moving component 320 can drive the adsorbing component 310 to slide in the horizontal direction.

[0072] It can be selected that the moving component 320 drives the adsorbing component 310 to move in the vertical direction to lift the cover plate. Then, the moving component 320 can move the adsorbing component 310 adsorbing the cover plate to a safe position on one side of the cable trench in the horizontal direction. The adsorbing component 310 releases the cover plate to complete the cover plate opening process. Conversely, when the operation is over and the cover plate needs to be closed, the moving component 320 can operate in the reverse path.

[0073] The walking drive assembly 400 is located at the bottom of the vehicle frame 100 and can drive the entire vehicle frame 100 to move freely above the cable trench or on the surrounding roads, which is convenient for the device to quickly reach the operation location and move for operation at the operation location. Thus, after the adsorbing component 310 and the moving component 320 cooperate to move the cover plate of the maintenance opening away, the operation opening 110 can be opposite to the maintenance opening.

[0074] When the cable trench mobile maintenance device provided in this embodiment is specifically used, the walking drive assembly 400 drives the frame 100 to move, so that the suction component 310 moves above the cover plate of the maintenance opening. The moving component 320 drives the suction component 310 to move downward to be adsorbed and connected to the cover plate, and then the moving component 320 drives the suction component 310 to carry the cover plate upward to remove the cover plate from the maintenance opening.

[0075] After the cover plate is removed from the maintenance opening, the walking drive assembly 400 drives the frame 100 to move, so that the operation opening 110 is opposite to the maintenance opening. The staff stands in the operation bin 210, and the operation bin 210 moves downward to enter the cable trench through the operation opening 110 and the maintenance opening, and the staff performs maintenance operations in the operation bin 210.

[0076] After the staff completes the maintenance, the operation bin 210 moves upward to get out of the maintenance opening; the walking drive assembly 400 drives the frame 100 to move to the position where the cover plate on the suction component 310 is opposite to the maintenance opening, and the moving component 320 drives the suction component 310 to carry the cover plate downward to cover the cover plate on the maintenance opening; then the walking drive assembly 400 drives the frame 100 to move to other positions that need to be maintained.

[0077] The cable trench mobile maintenance device provided in this embodiment includes a frame 100, a maintenance operation assembly 200, a cover plate moving assembly 300 and a walking drive assembly 400. The maintenance operation assembly 200, the cover plate moving assembly 300 and the walking drive assembly 400 are arranged on the frame 100. The suction component 310 and the moving component 320 of the cover plate moving assembly 300 cooperate with each other to be able to move the cover plate out of the maintenance opening, and the walking drive assembly 400 can drive the frame 100 to move to the position where the operation opening 110 is opposite to the maintenance opening, so that the operation bin 210 carries the staff to descend into the cable trench through the operation opening 110 and the maintenance opening for maintenance. The operation bin 210 of the maintenance operation assembly 200 provides a movable platform for the staff to get on and off the cable trench, reducing the accidental contact of the staff with the live cables or other components in the cable trench, and reducing the situations such as slipping and falling of the staff due to the wet and slippery environment of the cable trench, and providing the safety of the staff's maintenance. The cover plate moving assembly 300 can move the cover plate above the cable trench away and put it back in place, realizing the operation of automatically opening and closing the maintenance opening, and the frame 100 can move to different maintenance openings, so that the staff can move with the frame 100 for continuous operation, reducing the labor intensity of entering and leaving the cable trench and opening and closing the cover plate, and improving the efficiency and safety of cable trench operations.

[0078] Please refer to Figures 3 to 5 , in an alternative embodiment, the operation bin 210 is provided with an openable and closable perspective window 213. The perspective window 213 includes a frame body 213a and a transparent window body 213b, and the transparent window body 213b is hinged to the frame body 213a.

[0079] The perspective window 213 enables the staff to observe the situation inside the cable trench within the operation compartment 210 without exposing the whole body outside the cable trench, thus further improving the safety of the maintenance operation. It can be understood that the operation compartment 210 is provided with a window, and the window provides an installation space for the perspective window 213. The perspective window 213 is arranged facing the cables on both sides of the cable trench so that the staff can observe the situation outside the window. Specifically, the frame body 213a is installed on the window, and the transparent window body 213b is installed on the frame body 213a. The frame body 213a is provided with an installation opening, and the transparent window body 213b is hinged in the installation opening. When the transparent window body 213b is in the installation opening, the perspective window 213 is in the closed state. When the transparent window body 213b rotates to expose the installation opening on the frame body 213a, the perspective window 213 is in the open state.

[0080] Therefore, in the embodiment of the present application, through the transparent window body 213b, good working conditions are further provided for the staff. The staff can observe the environment inside the cable trench through the perspective window 213, and can open the perspective window 213 to perform maintenance operations on the cables inside the cable trench, improving the flexibility and safety of the maintenance work.

[0081] Please refer to Figure 5 , in an alternative embodiment, a plurality of perspective windows 213 are provided, and the plurality of perspective windows 213 are arranged vertically along the operation compartment 210.

[0082] At least two perspective windows 213 can be selected; during maintenance, the staff can select to open one or more of the perspective windows 213 for operation according to actual needs, improving the flexibility of the operation. Therefore, during the operation process, the staff can selectively open the transparent window body 213b for operation without the need to open all of them, thus reducing the risk of accidental injury. The vertically arranged perspective windows 213 can provide the staff with views at different heights, facilitating the staff to observe the cable conditions at different heights inside the operation compartment 210. Compared with the horizontal arrangement, the vertically arranged perspective windows 213 can make more effective use of the space inside the operation compartment 210 and avoid occupying too much horizontal space.

[0083] Refer to Figures 1 to 5 As shown, in an alternative embodiment, the maintenance operation assembly 200 further includes a first frame body 220 and a first lifting driving member 230; the first frame body 220 is provided on the vehicle frame 100; the first lifting driving member 230 is provided on the first frame body 220, and the output part of the first lifting driving member 230 is connected to the operation compartment 210 to drive the operation compartment 210 to move relative to the vehicle frame 100 in the vertical direction.

[0084] The first frame body 220 is installed at the operation port 110 of the vehicle frame 100. As the basic structure of the entire maintenance operation assembly 200, the first frame body 220 plays a role in supporting and stabilizing the operation bin 210, and the operation bin 210 is installed on the first frame body 220 through the first lifting driving member 230.

[0085] The first lifting driving member 230 can be selected as a lead screw and a motor. The motor is installed on the first frame body 220, the lead screw is arranged in the vertical direction, a threaded hole is provided on the side of the operation bin 210, and the threaded hole is threadedly connected with the lead screw. The motor drives the lead screw to rotate, so that the lead screw drives the operation bin 210 to move relative to the vehicle frame 100 in the vertical direction under the action of the thread. Of course, the first lifting driving member 230 can also be selected as a telescopic air cylinder. The telescopic air cylinder is connected with the first frame body 220, the telescopic end of the telescopic air cylinder can telescopically extend and retract in the vertical direction, the telescopic end is connected with the operation bin 210, and the telescopic end telescoping in the vertical direction can drive the operation bin 210 to move relative to the vehicle frame 100 in the vertical direction.

[0086] The first lifting driving member 230 drives the operation bin 210 to move in the vertical direction, and the height of the operation bin 210 can be adjusted according to needs, so as to reach different depths of the cable trench for maintenance operations, thereby avoiding the physical labor of manually climbing ladders, reducing the fatigue and safety hazards caused by the frequent up and down movement of the staff, and being beneficial to improving the work efficiency of the maintenance operation.

[0087] When designing the cable trench, it is necessary to consider the number and type of cables to be accommodated in the cable trench and the possible future expansion requirements. The changes in the dimensions of the cable trench, including depth, width and shape, will cause the supporting covers to also need different dimensions to adapt to these changes. For example, the more cables need to be installed, or the thicker a single cable is, the greater the width and depth of the cable trench need to be; considering the possible future increase in cable load, a certain expansion space is usually reserved in the cable trench. In this way, different cable trenches have different width dimensions, and the operation bin 210 of the cable trench maintenance device provided by the embodiment of the present application is restricted by the cable trenches with different width dimensions, which will affect the entry and exit of the operation bin 210, and it may be difficult for the staff to smoothly put the operation bin 210 into or pull it out of the cable trench.

[0088] In view of the above situation, please refer to Figure 5 , in an alternative embodiment, the operation bin 210 includes a first bin body 211 and a second bin body 212 that are oppositely arranged in the transverse direction, and the first bin body 211 is slidably connected to the second bin body 212; at least one of the first bin body 211 and the second bin body 212 is connected to the output part of the first lifting driving member 230.

[0089] The sliding connection between the first bin body 211 and the second bin body 212 enables the total width of the operation bin 210 to be adjusted according to the actual size of the cable trench cover plate, so as to adapt to cable trench cover plates of different sizes. The adjustability of the width of the operation bin 210 makes it more convenient for the staff to put the operation bin 210 into or pull it out of the cable trench, improving the efficiency of maintenance work. In addition, when the operation bin 210 is not in use, the first bin body 211 and the second bin body 212 of the operation bin 210 can be closed together, reducing the overall occupied space and facilitating the transportation and storage of the operation bin 210.

[0090] Exemplarily, the first bin body 211 is provided with a sliding groove in the transverse direction, and the second bin body 212 includes a sliding connection portion which is slidably connected to the sliding groove. The sliding connection portion is arranged in the sliding groove and can slide in the sliding groove, so that the distance between the first bin body 211 and the second bin body 212 can be adjusted, thereby changing the total width of the operation bin 210. The sliding groove provides a guiding function for the sliding of the sliding connection portion, so that while the width of the operation bin 210 is adjusted, the stability of the overall structure of the operation bin 210 is not affected. Optionally, the first bin body 211 is provided with sliding grooves in both the transverse and vertical directions, and a part of the second bin body 212 is inserted into the sliding grooves as the sliding connection portion, and through the sliding connection in the vertical and transverse directions, the sliding connection stability between the first bin body 211 and the second bin body 212 is further improved.

[0091] It can be selected that the first bin body 211 is connected to the output part of the first lifting drive member 230, and the second bin body 212 is slidably connected to the first bin body 211, so that the first lifting drive member 230 drives the first bin body 211 to move in the vertical direction, and the second bin body 212 moves together with the first bin body 211; of course, it can also be selected that the second bin body 212 is connected to the output part of the first lifting drive member 230, and the first bin body 211 is slidably connected to the second bin body 212, so that the first lifting drive member 230 drives the second bin body 212 to move in the vertical direction, and the first bin body 211 moves together with the second bin body 212; or it can also be selected that both the first bin body 211 and the second bin body 212 are connected to the output part of the first lifting drive member 230. Taking the relative sliding direction of the first bin body 211 and the second bin body 212 as the first direction, both the first bin body 211 and the second bin body 212 are slidably connected to the output part of the first lifting drive member 230 along the first direction, so that the first bin body 211 and the second bin body 212 can slide relative to each other to adjust the width size of the cover plate operation bin 210.

[0092] At least one of the first bin body 211 and the second bin body 212 is connected to the output part of the first lifting drive member 230, so that the first lifting drive member 230 can drive at least one of the first bin body 211 and the second bin body 212, ensuring that the first lifting drive member 230 can drive the operation bin 210 to move in the vertical direction.

[0093] Please refer to Figure 3 and Figure 4 , in an alternative embodiment, the maintenance operation assembly 200 includes a first guide rod 240 and a first lateral drive member 250.

[0094] The first frame 220 is provided on the vehicle frame 100, the first lifting drive member 230 is provided on the first frame 220, and the output portion of the first lifting drive member 230 is connected to the operation bin 210; the first guide rod 240 is arranged on the first frame 220 along the sliding direction of the first bin 211 and the second bin 212, and both the first bin 211 and the second bin 212 are slidably connected to the first guide rod 240; the first lateral drive member 250 is used to drive the first bin 211 to approach and move away from the second bin 212.

[0095] The first guide rod 240 provides guidance for the relative sliding of the first bin 211 and the second bin 212, enabling the first bin 211 to slide smoothly relative to the second bin 212, which is beneficial to improving the stability of the operation bin 210 when adjusting the width. And the first lifting drive member 230 can drive the first guide rod 240 to move in the vertical direction, and the movement of the first guide rod 240 can drive the first bin 211 and the second bin 212 to move simultaneously, enhancing the stability of the operation bin 210 when lifting.

[0096] The first lateral drive member 250 functions to adjust the distance between the first bin 211 and the second bin 212. It can drive only the first bin 211 or only the second bin 212, or drive both the first bin 211 and the second bin 212 simultaneously. For example, the first lateral drive member 250 is a telescopic air cylinder, and both ends of the telescopic air cylinder are respectively connected to the first bin 211 and the second bin 212 along the first direction, so that when the telescopic air cylinder extends, the first bin 211 and the second bin 212 move away from each other, and when the telescopic air cylinder contracts, the first bin 211 and the second bin 212 move closer to each other.

[0097] It is also possible to select that the first lateral drive member 250 includes a lead screw and a motor. The motor is connected to the output portion of the first lifting drive member 230, the lead screw is connected to the motor, and the lead screw is arranged along the first direction. It can be selected that the first bin 211 is provided with a threaded hole, and the lead screw is in threaded cooperation with the threaded hole of the first bin 211, so that when the motor drives the lead screw to rotate, it can drive the first bin 211 to move in the first direction to adjust the distance between the first bin 211 and the second bin 212. Or it can be selected that the second bin 212 is provided with a threaded hole, and the lead screw is in threaded cooperation with the threaded hole of the second bin 212, so that when the motor drives the lead screw to rotate, it can drive the second bin 212 to move in the first direction to adjust the distance between the first bin 211 and the second bin 212.

[0098] Of course, it is not limited to the first lateral driving member 250 including a first lead screw, a second lead screw, a first motor, and a second motor. Both the first motor and the second motor are connected to the output part of the first lifting driving member 230. The first lead screw and the second lead screw are both arranged along the first direction. The first lead screw is connected to the first motor. Screw holes are provided on both the first bin body 211 and the second bin body 212. The first lead screw is in threaded cooperation with the screw hole of the first bin body 211, and the second lead screw is in threaded cooperation with the screw hole of the second bin body 212. When the first motor drives the first lead screw to rotate, it can drive the first bin body 211 to move along the first direction. When the second motor drives the second lead screw to rotate, it can drive the second bin body to move along the first direction.

[0099] Through the operation of the first lateral driving member 250, the staff can easily adjust the width of the operation bin 210, improving the flexibility of the operation. The first lateral driving member 250 can be in manual or electric form, and mechanical driving is preferably adopted, such as devices like telescopic motors, lead screw transmission mechanisms, hydraulic cylinders, etc.

[0100] In an alternative embodiment, the first lifting driving member 230 is a lead screw transmission mechanism. The lead screw transmission mechanism includes a lead screw, a sliding seat, and a motor. The lead screw is arranged vertically on the first frame body 220. The sliding seat is arranged on the lead screw and is slidably connected to the lead screw. The motor can drive the lead screw to rotate. The lead screw provides guidance for the sliding seat to ensure that the sliding seat can move up and down smoothly along the lead screw. The sliding seat is connected between the lead screw and the operation bin 210, so that the operation bin 210 can be lifted and lowered as the sliding seat moves up and down. Through the drive of the motor, the lead screw can rotate, thereby driving the sliding seat to move up and down along the lead screw to realize the lifting of the operation bin 210.

[0101] Please refer to Figure 6 and Figure 7 , in an alternative embodiment, the moving member 320 includes a second frame body 321, a sliding frame 322, a second lifting driving member 323, and a connecting seat 324.

[0102] The second frame body 321 is arranged on the vehicle frame 100; the sliding frame 322 is slidably arranged on the second frame body 321, and the sliding frame 322 can slide horizontally relative to the second frame body 321. The second lifting driving member 323 is arranged on the sliding frame 322. The connecting seat 324 is arranged on the output part of the second lifting driving member 323. The second lifting driving member 323 is configured to drive the connecting seat 324 to move vertically relative to the sliding frame 322; the connecting seat 324 is connected to the suction member 310.

[0103] It should be noted that in the embodiments of the present application, the horizontal direction is the horizontal direction of the second frame body 321, and the vertical direction is the vertical direction of the second frame body 321. For the convenience of indicating the horizontal and vertical directions, refer to Figure 1 , the horizontal direction is the X direction, and the vertical direction is the Y direction.

[0104] The sliding frame 322 is a frame structure that can move horizontally along the second frame body 321. The second lifting drive 323 is installed on the sliding frame 322. The suction attachment 310 is connected to the second lifting drive 323 through a connecting seat 324. Thus, the suction attachment 310 can move along with the sliding frame 322, so as to move the cover plate horizontally out of or into the cable trench from above, that is, move horizontally along the second frame body 321, reducing the need for manual handling of the cover plate.

[0105] The suction attachment 310 is connected to the connecting seat 324, and the connecting seat 324 is fixedly connected to the output part of the lifting drive, so that the suction attachment 310 can move vertically along with the output part of the second lifting drive 323, that is, vertically along the second frame body 321, thereby realizing the actions of lifting and lowering the cover plate, effectively reducing the labor intensity of manual handling.

[0106] Among them, the second lifting drive 323 can adopt drive devices such as a screw drive mechanism, a telescopic motor, etc. Exemplarily, the second lifting drive 323 is a screw drive mechanism, and the connecting seat 324 is driven through a screw and a screw slider, thereby driving the suction attachment 310 to lift and lower vertically.

[0107] When it is necessary to move the cover plate on the cable trench, first, the cable trench mobile maintenance device drives the cover plate moving assembly 300 to move to the position of the cover plate to be moved. By controlling the horizontal movement of the sliding frame 322 along the slide rail 325 of the second frame body 321, the suction attachment 310 is aligned with the center position of the cover plate; then, the second lifting drive 323 is used to control the suction attachment 310 to descend to the surface of the cover plate. When the suction attachment 310 contacts the cover plate, sufficient suction force is generated to suck the cover plate, and the suction frame 311 together with the cover plate rises until the cover plate completely disengages from the maintenance opening; after that, the operator controls the sliding frame 322 to move horizontally again to move the cover plate to the designated position, and then reversely operates the second lifting drive 323 to slowly lower the cover plate to the ground or other designated positions, release the negative pressure of the suction attachment 310, and release the cover plate; finally, after completing the cover plate placement operation, the entire moving member 320 is reset to the initial state for the next use.

[0108] Therefore, in the embodiment of the present application, the cover plate is lifted and lowered by the suction attachment 310, and then through the horizontal movement of the sliding frame 322 and the vertical drive of the lifting drive, the lifted cover plate can move in the horizontal direction and the vertical direction. Thus, the automatic handling of the cover plate is realized, the labor intensity of the staff is reduced, and the work efficiency is significantly improved.

[0109] Please continue to refer to Figure 6 and Figure 7 , in an optional embodiment, the moving member 320 further includes a slide rail 325, a pulley 326, a second guide rod 327 and a second lateral drive 328.

[0110] The slide rail 325 is transversely arranged on the second frame body 321. The pulley 326 is arranged on the sliding frame 322, and the pulley 326 is in rolling cooperation with the slide rail 325. The second guide rod 327 is arranged on the second frame body 321 along the sliding direction of the sliding frame 322, and the sliding frame 322 is slidably connected with the second guide rod 327. Arranged on the second frame body 321, the second transverse driving member 328 is configured to drive the sliding frame 322 to slide transversely relative to the second frame body 321.

[0111] The slide rail 325 provides guidance for the sliding frame 322 to guide the sliding frame 322 to move along a predetermined trajectory. The pulley 326 is installed on the sliding frame 322. The pulley 326 cooperates with the slide rail 325, which can reduce the frictional force between the sliding frame 322 and the slide rail 325, is beneficial to the smooth movement of the sliding frame 322, reduces friction, and improves the movement efficiency. The second guide rod 327 further provides guidance and support for the sliding frame 322, reduces the shaking of the sliding frame 322 during transverse movement, and improves the installation stability and movement stability of the sliding frame 322.

[0112] The second transverse driving member 328 can be a driving device such as a screw drive mechanism, a telescopic motor, a piston cylinder, a cylinder or a hydraulic cylinder. Exemplarily, the second transverse driving member 328 is a screw drive mechanism for driving the sliding frame 322 to move transversely, and then driving the suction attachment 310 to move. The second transverse driving member 328 includes a screw, a sliding seat and a motor. The screw is transversely arranged on the second frame body 321; the sliding seat is slidably connected to the screw, and the sliding seat is connected to the sliding frame 322; the motor can drive the screw to rotate so that the sliding seat slides transversely.

[0113] In an alternative embodiment, the sliding frame 322 includes a sliding portion sleeved on the second guide rod 327, and the sliding portion is in sliding cooperation with the second guide rod 327. The sliding portion is a sleeve or an open slot. The sliding portion is sleeved on the guide rod. Through the sliding cooperation between the sliding portion and the second guide rod 327, it is beneficial to improve the stability of the sliding frame 322.

[0114] Refer to Figure 6 and Figure 7As shown, in some optional embodiments, the adsorbent 310 uses the principle of atmospheric pressure difference to generate sufficient negative pressure through the seal between the adsorbent 310 and the cover plate surface. Specifically, the adsorbent 310 includes an adsorption frame 311, a vacuum pump 313, a diverter 314, an air pipe 315 and a plurality of suction cups 312, the adsorption frame 311 is arranged at the output part of the moving member 320, and a plurality of suction cups 312 are arranged on the adsorption frame 311, and the vacuum pump 313, the diverter 314 and the plurality of suction cups 312 are connected in sequence through the air pipe 315. The number of suction cups 312 can be selected according to the size and weight of the cover plate to ensure sufficient adsorption force. The vacuum pump 313 reduces the pressure inside the suction cup 312 by extracting air, thereby forming a negative pressure area between the suction cup 312 and the cover plate. The diverter 314 evenly distributes the negative pressure generated by the vacuum pump 313 to the plurality of suction cups 312, so that each suction cup 312 can obtain sufficient adsorption force.

[0115] During the use of the adsorbent 310, first, the suction cup 312 is placed close to the cover plate, and then the vacuum pump 313 is started to extract the air inside the suction cup 312 through the air pipe 315 and the diverter 314. The negative pressure formed by the suction cup 312 can firmly adsorb the cover plate; when the cover plate needs to be put down, the vacuum pump 313 is turned off to release the negative pressure in the suction cup 312, and the suction cup 312 releases the cover plate.

[0116] Reference Figure 1 and Figure 2 As shown, in an optional embodiment, the travel drive assembly 400 includes a wheel 410 and a motor 430 ; the wheel 410 is disposed on the frame 100 ; the motor 430 is disposed on the frame 100 , and the motor 430 is transmission-connected to the wheel 410 .

[0117] The wheel 410 is the direct component of the travel drive assembly 400 that contacts the ground and is responsible for providing the necessary traction and support. The motor 430 is the power source of the travel drive assembly 400 and provides the necessary torque and speed to drive the wheel 410 to rotate. The wheel 410 can be connected to the output shaft of the motor 430 so that the motor 430 can directly drive the wheel 410 to rotate.

[0118] Of course, it is also possible to choose that the travel drive assembly 400 includes a wheel 410, a transmission shaft 420, and a motor 430, the wheel 410 is set on the frame 100, the transmission shaft 420 is connected to the wheel 410, the motor 430 is set on the frame 100, the motor 430 is connected to the transmission shaft 420 to drive the transmission shaft 420 and the wheel 410 to rotate.

[0119] The drive shaft 420 connects the wheel 410 and the motor 430, transmits the power generated by the motor 430 to the wheel 410, and thus drives the wheel 410 to rotate. Optionally, the cover plate moving assembly 300 and the traveling drive assembly 400 are arranged at both ends of the frame 100, and the maintenance operation assembly 200 is arranged between the cover plate moving assembly 300 and the traveling drive assembly 400; Optionally, the motor 430 is on the side of the wheel 410 facing away from the cover plate moving assembly 300, and the drive shaft 420 is arranged on the side of the motor 430 facing the cover plate moving assembly 300 and is connected to the output end of the motor through a transmission method such as gears, chains or belts. The drive shaft 420 is connected to the rotating shaft of the wheel 410, so that the motor 430 can drive the wheel 410 to rotate through the drive shaft 420.

[0120] Optionally, a speed reducer 440 can be arranged on the motor 430. The speed reducer 440 can reduce the output speed of the motor 430 and increase the output torque at the same time to meet the rotation requirements of the wheel 410. In this embodiment, the speed reducer 440 can be connected to the motor 430 and the drive shaft 420 through a transmission method such as a coupling or gears. During operation, the power generated by the motor 430 is reduced to a speed suitable for the rotation of the wheel 410 through the speed reducer 440 and is transmitted to the wheel 410 through the drive shaft 420. The frictional force between the wheel 410 and the ground generates a traction force to push the entire device forward.

[0121] In some scenarios, in order to make the entire device better adapt to mountainous and sandy environments, a crawler is sleeved on the wheel 410 to increase the frictional force during walking and make it have better grip performance. For example Figure 1 and Figure 2 as shown, the crawler requires the wheel 410 to have multiple sub-wheels. Optionally, one sub-wheel is directly connected to the output shaft of the motor 430, and the drive shaft 420 of the motor 430 arranged towards the cover plate moving assembly 300 is connected to one of the remaining sub-wheels.

[0122] In an optional embodiment, the cable trench mobile maintenance device further includes a controller, and the maintenance operation assembly 200, the cover plate moving assembly 300 and the traveling drive assembly 400 are all electrically connected to the controller.

[0123] It can be understood that the controller is connected to each component such as the maintenance operation assembly 200, the cover plate moving assembly 300 and the traveling drive assembly 400 through electrical connection, and can control their operating states in real time, such as functions of starting, stopping, accelerating, decelerating, steering, etc.

[0124] Furthermore, a driver's seat for controlling the entire device can be arranged on the frame 100. The driver's seat is provided with components such as a console and a controller. The console is provided with a steering wheel, a human-machine interaction interface, etc.

[0125] Optionally, the controller is a PLC controller, which can receive operation instructions from a human-machine interface such as a touch screen, a remote controller, etc., and control the coordinated work of various components such as the maintenance operation component 200, the cover plate moving component 300, and the traveling drive component 400 according to the instructions. For example, when an operator issues a moving instruction through the touch screen, the PLC controller will parse the instruction and control the motor 430 and the reducer 440 in the traveling drive component 400 through the output module, so that the device moves in the specified direction and speed.

[0126] When the cable trench mobile maintenance device provided by the present application is specifically used, the motor 430 drives the wheels 410 to roll to drive the frame 100 to move. When the frame moves to a position where a plurality of suction cups 312 are located above the cover plate of the maintenance opening, the movement stops. The second lifting drive member 323 drives the connecting seat 324 to move downward so that the plurality of suction cups 312 on the suction frame 311 are adsorbed and connected to the cover plate. Then, the moving member 320 drives the suction member 310 to carry the cover plate upward to disengage the cover plate from the maintenance opening.

[0127] After the cover plate is disengaged from the maintenance opening, the traveling drive component 400 drives the frame 100 to move so that the operation opening 110 is disposed opposite to the maintenance opening. The first lateral drive member 250 is used to drive the first cavity 211 and the second cavity 212 of the operation cavity 210 to slide relative to each other to adjust the width of the operation cavity 210. The staff stands in the operation cavity 210, and the operation cavity 210 moves downward to enter the cable trench through the operation opening 110 and the maintenance opening. The staff performs maintenance operations in the operation cavity 210 through a plurality of perspective windows 213.

[0128] After the staff completes the maintenance, the first lifting drive member 230 drives the operation cavity 210 to move upward so that the operation cavity 210 moves to the upper side of the operation opening 110. The traveling drive component 400 drives the frame 100 to move to a position where the cover plate on the suction member 310 is opposite to the maintenance opening. The moving member 320 drives the suction member 310 to carry the cover plate downward so that the cover plate covers the maintenance opening. The staff remains standing in the operation cavity 210, and the traveling drive component 400 drives the frame 100 to carry the staff to move to other positions that need to be maintained, and repeats the above operations to maintain different positions of the cable trench.
