[0002] With the rapid development of urbanization, underground comprehensive as the public tunnel of intensive laying of various municipal pipelines has been constructed on a large scale in the country, but the top space is generally idle and wasted. According to the statistics of the Ministry of Housing and Urban-Rural Development in 2024, more than 9000 kilometers of comprehensive have been built in China, the average height of the idle space on the top is 1.2 meters, and the utilization rate is less than 8%. At the same time, the urban logistics system is facing severe challenges: the construction area is located in the traffic arteries, densely populated areas and important business districts. Compared with transportation, the daily driving distance of urban express vehicles needs to increase by 35%, and the cost of "the last mile" has risen to 32.7%. At present, there are some attempts to use the bottom space for logistics transmission at home and abroad, but there is no systematic and intelligent use of the idle space on the top to build a logistics network that adapts to different scales (including small).

[0003] The existing bottom logistics transmission scheme has significant limitations: first, the function is single, only designed for internal operation and maintenance material transportation, not effectively connected with the urban ground logistics network (such as commercial buildings and communities), and cannot meet the social express logistics demand; second, the intelligent degree is low, the automation level is limited, and a large amount of manual intervention is needed, resulting in low transmission efficiency and difficulty in realizing precise and efficient unmanned operation; third, it lacks systematization, and is mostly a simple transportation tool without building a complete closed-loop system including vertical transmission, horizontal transmission and intelligent delivery. In addition, for efficient use of the idle space on the top, there is no systematic and intelligent logistics network solution that adapts to different scales, which cannot solve the problems of space idling and "the last mile" logistics. SUMMARY

[0006] The present application utilizes the idle space on the top of the pipe gallery to build a track-type logistics transportation framework, and realizes the automatic transportation of goods in the pipe gallery and the connection with the ground logistics network through the combination design of mechanical movement and ground connection: the trolley system is fixed on the top along the pipe gallery line as the main road of the entire logistics transportation, which adopts track-type design, provides stable movement path for the slider device through the guidance of rigid track, and relies on the structural strength of the track to bear the weight of goods and the slider device, the trolley system can be customized according to the actual length, width or turning radius of the pipe gallery, and is suitable for different specifications of pipe gallery space; the slider device is used as the carrier of goods transportation, and realizes the automatic horizontal movement along the track through the cooperation with the trolley transmission, which can complete the long-distance transportation of goods in the pipe gallery, and realizes the quick loading and unloading of goods through the detachable hoisting mode, while supporting the grouping transportation of single or multiple slider devices, which is suitable for different scales of logistics demand; the ground access system is arranged at the key nodes of the trolley system and is connected with the ground, realizes the transfer of goods between the top of the pipe gallery and the ground through the vertical transmission mechanism, breaks the physical isolation between the inside of the pipe gallery and the ground logistics network, and can be connected with the ground facilities such as express cabinet, logistics station and the like in commercial buildings and communities.

[0007] The advantage of the present application is that the existing scheme focuses on the bottom of the pipe gallery, which not only occupies the operation channel, but also has the problem of low space utilization, while the system of the present application utilizes the idle space on the top of the pipe gallery to build a transportation track, which does not affect the original operation of the bottom of the pipe gallery, realizes the "three-dimensional utilization" of the pipe gallery space, relies on the top space construction of the existing pipe gallery, does not need additional land acquisition or new ground logistics channel, greatly reduces the construction cost of urban logistics infrastructure, the automatic operation mode reduces the labor cost, and the mechanical structure of the trolley system and the slider device is simple to maintain, and the operation and maintenance cost is much lower than the traditional manual logistics distribution mode; the intelligent scheduling system can be linked between the subsystems of the present application, which is suitable for the logistics scene of the "last mile" in the city, realizes the rapid transfer and delivery of goods, and forms an integrated logistics operation system.

[0008] Further, the trolley system includes a main rail module and a plurality of sub-rail modules, and the ground access system is arranged at the junction of the main rail module and each sub-rail module. The main rail module comprises a plate bearing main rail fixed on the top of the pipe gallery and arranged along the pipe gallery line, and a cable traction main cable; the sub-rail module comprises a plate bearing sub-rail fixed on the top of the pipe gallery and located at each ground access system position, and a cable traction sub-cable; the plate bearing sub-rail is composed of two transition sections parallel to the plate bearing main rail and a sub-packaging section located between the two transition sections, and the sub-packaging section extends to the ground access system position; The slider device comprises a main body, first and second cable pressing wheels symmetrically arranged on the main body, first and second limiters arranged on the main body and used for limiting the movement of the first and second cable pressing wheels on the plate bearing main rail and the plate bearing sub-rail respectively, first and second cable releasing grippers symmetrically arranged on the main body and used for clamping or releasing the cable traction main cable and the cable traction sub-cable respectively, and a connector arranged at the lower part of the main body and used for hoisting goods. Preferably, during loading, the slider device moves from the sub-rail module to the main rail module through the transition section; during transportation, the slider device moves on the main rail module; and during sub-packaging and unloading, the slider device moves from the main rail module to the sub-packaging section through the transition section.

[0009] Preferably, during transportation, the first cable releasing gripper clamps the cable traction main cable and pulls the slider device to move forward, and the first limiter limits the movement of the first cable pressing wheel on the plate bearing main rail; when it is necessary to switch into the sub-packaging point for unloading, the first and second cable pressing wheels enter the plate bearing main rail and the plate bearing sub-rail which are parallel to each other at the transition section of the sub-rail module, at this time, the first cable releasing gripper releases the clamping of the cable traction main cable, the first limiter releases the limitation of the plate bearing main rail on the first cable pressing wheel, at the same time, the second cable releasing gripper clamps the cable traction sub-cable, the second limiter limits the second cable pressing wheel on the plate bearing sub-rail, and the slider device is pulled by the cable traction sub-cable to turn and separate from the main rail module to enter the sub-packaging section of the sub-rail module to load and unload goods; when it is necessary to load, the above reverse operation is performed, which will not be described herein again. The overhead monorail system of the present application comprises a main rail module and a sub-rail module, forming a rail network of trunk lines and branch lines, the main rail module serving as a trunk channel for logistics transportation, being arranged along the pipe gallery line in a ring shape and bearing the long-distance and cross-regional horizontal transportation task of the slider device in the pipe gallery, the ring-shaped design of which can realize the circulation of the slider device, and the sub-rail module serving as a branch channel and being arranged corresponding to each ground access system, bearing the sub-stream transportation task of goods from the main rail to the ground access point; the ground access system is arranged at the junction of the main rail and the sub-rail, taking advantage of the space of the rail intersection to realize seamless switching and vertical transfer between the main rail module and the sub-rail module, avoiding additional transfer links.

[0010] Preferably, the plate type bearing main rail of the main rail module and the plate type bearing sub-rail of the sub-rail module are fixed on the pipe gallery roof by plate type rigid structure, and the planar bearing characteristics of the plate type structure provide a stable support platform for the slider device, and the flatness of the plate type rail ensures the smoothness of the slider device during movement.

[0011] Preferably, the plate type bearing sub-rail includes two transition sections and a sub-loading section, the transition sections are parallel to the plate type bearing main rail, and the smooth cutting of the slider device from the main rail to the sub-rail is realized; the sub-loading section extends to the position of the ground loading and unloading system, and the turning design of the rail guides the slider device to accurately reach the unloading point, solving the path guiding problem of the goods from horizontal transportation to vertical unloading.

[0012] Further, the cable type traction main cable includes a steel cable, a driving wheel and a driven wheel fixedly connected on the pipe gallery roof, and a driving device connected to the driving wheel at the output end, and the steel cable is annular and sleeved through each driving wheel and driven wheel.

[0013] Further, the structure of the cable type traction sub-cable is the same as that of the cable type traction main cable.

[0014] It should be noted that the steel cable is sleeved and passes through the driving wheel and the driven wheel to form a closed transmission loop, which not only bears the pulling force of the slider device, but also transmits the power of the driving device to the entire rail section through the circulation of the steel cable.

[0015] Preferably, the driving device can be a servo motor, a reduction motor, etc., which is connected to the driving wheel at the output end and drives the driving wheel to rotate, and the driving wheel drives the steel cable to move along the preset track through friction or meshing structure between the driving wheel and the steel cable, converting the rotary motion into forward motion of the steel cable to provide motion power for the slider device.

[0016] Preferably, the driven wheel plays a guiding and tensioning role, and is fixed at the rail turning position or the middle position of the long distance rail on the pipe gallery roof. The driven wheel can be connected with the support through the bearing, and is fixed on the pipe gallery roof through the support. The bearing can freely rotate with the movement of the steel cable, on the one hand, the driven wheel guides the steel cable to adhere to the rail direction to avoid deviation of the steel cable; on the other hand, a tensioning mechanism can be provided to adjust the position of the driven wheel to maintain the constant tension of the steel cable and prevent the power transmission from failing due to relaxation of the steel cable.

[0017] Further, the first cable pressing wheel includes a plurality of rollers rotatably connected to the main body and arranged in sequence from front to back; the structure of the second cable pressing wheel is the same as that of the first cable pressing wheel. Preferably, the pressure cable wheel is composed of several front and rear arranged rollers, which are rotatably connected to the slider body through high-precision bearings. This arrangement changes the contact between the slider device and the plate bearing rail from a single point to multiple points, disperses the local pressure of the goods weight on the rail, and avoids deformation of the rail or wear of the roller caused by excessive force on a single point. At the same time, the synchronous rolling of multiple rollers can reduce the bumping and jamming during the movement of the slider, especially at the turning or joint of the rail, which can achieve smooth transition through the sequential contact of the rollers, and improve the stability of movement.

[0018] Further, the second limit stop includes a limit block rotatably connected to the main body through a rotating shaft, and an electrically controlled opening and closing device connected to the limit block and used for controlling the rotation of the limit block around the rotating shaft. Preferably, the limit block is rotatably connected to the slider body through a rotating shaft, and can realize two states of closing and opening around the rotating shaft. When the electrically controlled opening and closing device controls the block to close, the block and the slider body form a space surrounding the plate bearing main rail, which limits the first pressure cable wheel in the space to prevent the slider from moving off the track during movement. When the block is opened, the opening forms a passage with the track, allowing the first pressure cable wheel to smoothly separate from the plate bearing main rail, providing conditions for the slider to switch to the sub-rail module.

[0019] Preferably, the electrically controlled opening and closing device can be selected from an electromagnetic drive cylinder or an electric push rod, which is linked with the system intelligent controller. When the slider needs to continuously move on the main rail, the controller sends a command to make the opening and closing device drive the block to close, maintaining the limiting state. When the slider reaches the sub-rail transition section and needs to switch tracks, the controller receives a position signal and drives the opening and closing device to rotate the block around the rotating shaft to open, achieving unlocking.

[0020] Further, the first and second dismounting cable grippers are mechanical dismounting cable grippers, and the main rail module and each sub-rail module are respectively provided with a separation frame for triggering the mechanical dismounting and compression of the first and second dismounting cable grippers.

[0021] It should be noted that the mechanical release is the common release device of the existing cable car, which is the prior art, generally comprising a clamping mechanism and a trigger mechanism: wherein the clamping mechanism generally comprises a fixed jaw body, a movable jaw body and a return spring, the fixed jaw body is rigidly connected to the main body of the application, the movable jaw body is rotatably connected to the fixed jaw body through a pin shaft, one end of the return spring is connected to the fixed jaw body and the other end is connected to the movable jaw body, and under normal circumstances, the movable jaw body is pulled towards the fixed jaw body by the spring tension, so that the arc-shaped jaws of the two jaw bodies tightly hold the traction cable, forming a stable clamping state; wherein the trigger mechanism comprises a trigger lever and an unlocking cam, one end of the trigger lever extends outside the cable holder, the other end is rigidly connected to the unlocking cam, and the unlocking cam is attached to the linkage part of the movable jaw body, when the trigger lever is pushed by external force, the trigger lever is pressed down and pushes the movable jaw body, overcoming the tension of the return spring, so that the movable jaw body is separated from the fixed jaw body, realizing the disconnection of the cable holder and the cable.

[0022] It should be further pointed out that the separation frame provided in the application is the external force pushing mechanism for triggering the clamping and unlocking of the first release cable holder and the second release cable holder, which is the trigger mechanism for realizing the disconnection of the cable holder and the cable. The separation frame is in a frame structure as a whole, which is in a U shape, comprising guide rails at both ends and a release rail in the middle. When the unlocking cam at the end of the trigger lever on one side of the release cable holder first enters the guide rail of the separation frame, the cable holder maintains a stable posture and moves to the release rail until it reaches the release rail. The external force presses down and pushes the movable jaw body through the trigger lever, overcoming the tension of the return spring, so that the movable jaw body rotates around the pin shaft, the jaw gradually opens, the cable holder is separated from the traction cable, and the power transmission is interrupted.

[0023] Further, the separation frame comprises a first entrance separation frame and a second entrance separation frame respectively located on the main rail module and the sub-rail module at the entrance of the ground loading and unloading system along the direction of the forward movement of the goods, and a first exit separation frame and a second exit separation frame respectively located on the main rail module and the sub-rail module at the exit of the ground loading and unloading system; the installation starting positions of the first entrance separation frame and the second entrance separation frame are the same, the installation length of the first entrance separation frame covers the transition section to the sub-packaging section of the entrance, and the installation length of the second entrance separation frame is located in the transition section; the installation starting positions of the first exit separation frame and the second exit separation frame are the same, and the installation length of the first exit separation frame is smaller than the installation length of the second exit separation frame.

[0024] It should be noted that the separation frame is divided into four categories according to the "in-out direction" and the "corresponding track module", each of which undertakes the task of decoupling / resetting at a specific stage, forming a complete track switching link; the first import separation frame is arranged on the main track module of the ground import / export system import, and the core function is to trigger the slider device to release the cable type traction main cable to prepare for entering the sub-track module; the second import separation frame is arranged on the sub-track module of the ground import / export system import, and the core function is to trigger the sub-track separation frame to clamp the cable type traction sub-cable while the slider device is decoupled from the main track, completing the power source switching from the main track to the sub-track; conversely, the first export separation frame and the second export separation frame have the opposite switching effect.

[0025] It should also be noted that the starting end of the first import separation frame and the second import separation frame is aligned, which ensures that the slider device can contact the two types of separation frames at the same time when it moves to the import, and the main track separation frame triggers decoupling at the same time, and the sub-track separation frame triggers clamping, avoiding power interruption or switching delay; the length of the first import separation frame covers the transition section and the sub-packaging section, because after the slider enters the sub-track from the main track, it needs to move along the transition section to the sub-packaging section to reach the cargo loading and unloading area of the ground import / export system, and the longer first import separation frame can ensure that the first decoupling grip cable always remains in a released state when the slider device turns into the sub-packaging section, so that the slider device can smoothly turn into the sub-track module without being affected by the cable type traction main cable. The second decoupling grip cable is clamped; the length of the second import separation frame is only in the transition section, because the clamping action of the second decoupling grip cable on the cable type traction sub-cable needs to be completed before entering the sub-packaging section. The starting end of the first export separation frame and the second export separation frame is aligned, which ensures that the slider can synchronously contact the two types of separation frames when it returns from the sub-packaging section to the transition section, realizing the synchronous operation of decoupling from the sub-track and clamping the main track; the length of the second export separation frame is greater than that of the first export separation frame, because when the slider returns from the sub-track to the main track, the sub-track separation frame needs to first guide the slider device to decouple from the sub-track, then give the main track separation frame enough time to trigger the main track clamping, and the second decoupling grip cable always remains in a released state, so that the slider device can smoothly turn into the main track module without being affected by the cable type traction sub-cable. The first decoupling grip cable is clamped.

[0026] Further, the ground import / export system includes a ground well for connecting the ground and the underground pipe gallery space, an elevator arranged in the ground well, and a conveyor belt device extending to one end of the elevator, and the other end of the conveyor belt device extending below the sub-packaging section of the plate type bearing sub-track.

[0027] Preferably, the ground well is a rigid channel connecting the aboveground and underground pipe gallery, usually a square or circular well shaft made of concrete or metal, whose core function is to break through the physical isolation between the top of the pipe gallery and the ground. The size of the ground well needs to adapt to the lifting space of the elevator and the installation requirements of the conveyor belt device, and the inner wall of the well shaft will be provided with protective structures such as anti-falling guardrails and wear-resistant lining plates.

[0028] Preferably, the elevator is arranged inside the ground well, which is essentially a small guide rail type lifting platform composed of guide rails, lifting platforms, drive motors and safety locks, which can be applied by using existing technical equipment. The core function of the elevator is to receive the goods transported by the conveyor belt.

[0029] Preferably, the conveyor belt device is a horizontal bridge connecting the sub-track sub-assembly and the elevator, which is composed of a conveyor belt, a drive roller and a support bracket, which can be applied by using existing technical equipment.

[0030] It should be noted that the space of the top of the pipe gallery and the ground well is relatively narrow, and traditional large vertical transportation equipment cannot be installed. The design of the components of this system considers space adaptability.

[0031] It should be noted that the space of the top of the pipe gallery and the ground well is relatively narrow, and traditional large vertical transportation equipment cannot be installed. The design of the components of this system considers space adaptability.

[0032] Further, the connector is an automatic unhooker.

[0033] It should be noted that the automatic unhooker is generally composed of a lock hook assembly, a trigger mechanism, a reset spring and an electric control sensor, which can be applied by using existing technical equipment. The automatic unhooker is installed at the lower part of the sliding block device main body.

[0034] Further, it further includes a logistics box, the logistics box is connected with the connector, and the top of the logistics box is provided with a lifting ring. By setting a standard logistics box as a standardized load container for goods, the risk of collision, friction and moisture during multi-link transfer of goods can be reduced; the lifting ring is used as a connection interface between the logistics box and the automatic unhooker, and is fixed at the center position of the top of the logistics box. The structure design is accurately matched with the lock hook assembly of the automatic unhooker.

[0035] Further, it further includes a control system, the control system is connected with the overhead rail system, the sliding block device and the ground in-out cargo system.

[0036] Further, it further includes a plurality of code scanners for identifying goods, the code scanners are connected with the control system, and the code scanners are arranged at the positions of the overhead rail system and / or the ground in-out cargo system.

[0037] Need to explain, the control system and the joining of the code scanner is the core support of the pipe gallery logistics system from mechanical automation to intelligent informationization, and the two realize the whole link intelligent scheduling of cargo tracking, equipment linkage and process control.

[0038] Preferably, the code scanner cooperates with the existing two-dimensional code / bar code system for identification, and existing technical equipment can be used for application.

[0039] Preferably, the control system as the central brain of the pipe gallery logistics can adopt PLC and Internet of Things architecture, and is connected in real time with the overhead rail system, the sliding block device, the sensor and the actuator of the ground in-out cargo system through a data bus; wherein the control system collects key data through various sensors: such as in the overhead rail system, the running load of the main rail driving device and the cable tension are monitored through the motor current sensor and the cable tension sensor; such as in the sliding block device, the real-time coordinates of the sliding block are obtained through the position sensor, the engagement force of the automatic unhooking device and the lifting ring is detected through the pressure sensor, and the sliding block movement speed is monitored through the speed sensor; such as in the ground in-out cargo system, the height of the lifting platform is obtained through the displacement sensor of the elevator, whether the logistics box is in place is detected through the photoelectric sensor of the conveyor belt, and the logistics box load is judged through the weight sensor to avoid overload; all data are transmitted in real time to the control system through the Internet of Things module, and the control system issues instructions according to the collected data through the built-in preset program and algorithm, and carries out normal logistics scheduling: after the code scanner identifies the logistics box information, such as the destination rail number, the control system automatically plans the transportation path of the sliding block device, such as loading from a certain rail, transferring to another rail through the main rail, and synchronously instructing the overhead rail system to adjust the corresponding cable speed, instructing the sliding block device to complete the unhooking / hooking at the specified position, and instructing the ground in-out cargo system to coordinate the start-stop of the elevator and the conveyor belt; at the same time, the control system can also monitor the abnormal alarm of each system, such as if the cable tension sensor detects abnormal tension, the control system immediately instructs the driving device to stop, and at the same time sends a warning through the alarm module; if the sliding block position sensor detects deviation, the sliding block is instructed to adjust the direction to avoid collision with the rail; if the logistics box weight is overloaded, the elevator is instructed to stop ascending and wait for manual processing. The control system converts the control instructions into device actions through the execution components such as relays and frequency converters: such as instructing the electromagnetic push rod of the automatic unhooking device to be electrified to realize the opening of the double hooks; instructing the driving motor of the elevator to rotate forward to drive the lifting platform to rise; instructing the main rail driving device to adjust the frequency to change the cable movement speed to ensure the precise synchronization of each device action.

The ground-level cargo handling system 3 is located at a key node of the overhead rail system 1 and connects to the ground. Through a vertical transmission mechanism, it enables cargo transfer between the top of the utility tunnel 100 and the ground, breaking the physical isolation between the interior of the utility tunnel 100 and the urban ground logistics network. It can connect with ground facilities such as express delivery lockers and logistics stations in commercial buildings and communities.

[0049] like Figure 1 As shown, the overhead rail system 1 includes a main rail module 11 and several sub-rail modules 12, and the ground loading and unloading system 3 is located at the junction of the main rail module 11 and each sub-rail module 12. like Figure 2 and Figure 6As shown, the main rail module 11 includes the plate bearing main rail 111 fixed on the top of the pipe gallery 100 and arranged along the line of the pipe gallery 100 in a ring shape, and the cable traction main cable 112; the sub-rail module 12 includes the plate bearing sub-rail 121 fixed on the top of the pipe gallery 100 and located at the position of each ground access cargo system 3, and the cable traction sub-cable 122; the plate bearing sub-rail 121 is composed of two transition sections parallel to the plate bearing main rail 111, and a sub-assembly section located between the two transition sections, which extends to the position of the ground access cargo system by turning; As shown in Figure 3 , Figure 4 and Figure 5 , the slider device 2 includes a main body 21, a first pressure cable wheel 22 and a second pressure cable wheel 23 symmetrically arranged on the main body 21, a first limiter 24 and a second limiter 25 arranged on the main body 21 and used for limiting the movement of the first pressure cable wheel 22 and the second pressure cable wheel 23 on the plate bearing main rail 111 and the plate bearing sub-rail 121 respectively, a first unhooking cable gripper 26 and a second unhooking cable gripper 27 symmetrically arranged on the main body 21 and used for clamping or releasing the cable traction main cable 112 and the cable traction sub-cable 122 respectively, and a connector 28 arranged at the lower part of the main body 21 and used for hoisting cargo; In this embodiment, when loading cargo, the slider device 2 moves from the sub-rail module 12 to the main rail module 11 through the transition section; when transporting, the slider device 2 moves on the main rail module 11; when unloading, the slider device 2 moves from the main rail module 11 to the sub-assembly section through the transition section.

[0050] In this embodiment, when transporting, the first unhooking cable gripper 26 clamps the cable traction main cable 112 and pulls the slider device 2 to move forward, and the first limiter 24 limits the movement of the first pressure cable wheel 22 on the plate bearing main rail 111; when it is necessary to switch into the sub-assembly point for unloading, at the transition section of the sub-rail module 12, the first pressure cable wheel 22 and the second pressure cable wheel 23 enter the plate bearing main rail 111 and the plate bearing sub-rail 121 which are parallel to each other, at this time, the first unhooking cable gripper 26 releases the clamping of the cable traction main cable 112, the first limiter releases the limitation of the plate bearing main rail 111 on the first pressure cable wheel 22, at the same time, the second unhooking cable gripper 27 clamps the cable traction sub-cable 122, the second limiter limits the second pressure cable wheel 23 on the plate bearing sub-rail 121, and the slider device 2 turns to separate from the main rail module 11 and enters the sub-assembly section of the sub-rail module 12 for loading and unloading cargo under the traction of the cable traction sub-cable 122; when it is necessary to load cargo, the reverse operation is performed as described above, which will not be described here again; The hanging rail system 1 is divided into a main rail module 11 and a branch rail module 12 to form a track network of trunk lines and branch lines, the main rail module 11 serving as a trunk line channel for logistics transportation and being arranged annularly along the pipeline gallery 100 to undertake the long-distance and cross-region horizontal transportation task of the slider device 2 in the pipeline gallery 100, and the annular design can realize the circulating transportation of the slider device 2, and the branch rail module 12 serving as a branch line channel and being arranged corresponding to each ground access and delivery system 3 to undertake the shunting transportation task of goods from the main rail to the ground delivery point; the ground access and delivery system 3 is arranged at the junction of the main rail and the branch rail, and the space advantage of track intersection is utilized to realize seamless switching and vertical transfer of goods between the main rail module 11 and the branch rail module 12, and the additional transfer link is avoided.

[0051] In the embodiment, the plate type bearing main rail 111 of the main rail module 11 and the plate type bearing branch rail 121 of the branch rail module 12 are both fixed on the top of the pipeline gallery 100 in a plate type rigid structure, the surface bearing characteristic of the plate type structure provides a stable support platform for the slider device 2, and the flatness of the plate type track can ensure the smoothness of the slider device 2 during movement.

[0052] In the embodiment, the plate type bearing branch rail 121 includes two transition sections and a branch section, the transition sections are parallel to the plate type bearing main rail 111 to realize smooth cutting of the slider device 2 from the main rail to the branch rail, and the branch section extends to the position of the ground access and delivery system 3 in a turning manner to guide the slider device 2 to accurately arrive at the delivery point through the turning design of the track, thereby solving the path guiding problem of goods from horizontal transportation to vertical delivery.

[0053] As shown in Figure 2 The cable type traction main cable 112 includes a steel cable 1121, a driving wheel 1122 and a driven wheel 1123 fixedly connected on the top of the pipeline gallery 100, and a driving device connected to the driving wheel 1122, the steel cable 1121 is annular and sleeved through each driving wheel 1122 and driven wheel 1123.

[0054] In the embodiment, the structure of the cable type traction branch cable 122 is the same as that of the cable type traction main cable 112.

[0055] It should be noted that the steel cable 1121 is sleeved and wound around the driving wheel 1122 and the driven wheel 1123 to form a closed transmission loop, which not only bears the pulling force of the slider device 2, but also transmits the power of the driving device to the entire track section through the circulation of the steel cable 1121.

[0056] In the embodiment, the driving device can be a servo motor, a reduction motor or the like, which is connected to the driving wheel 1122 through an output end to drive the driving wheel 1122 to rotate, the driving wheel 1122 drives the steel cable 1121 to move along the preset track through friction or meshing structure between the driving wheel 1122 and the steel cable 1121, and converts the rotary motion into the forward motion of the steel cable 1121 to provide the motion power for the slider device 2.

[0057] In this embodiment, the guide and tensioning function is from the driven wheel 1123, which is fixed at the turning position of the track on the top of the pipe gallery 100 or the middle position of the long track. The driven wheel 1123 can be connected with the support through the bearing, and is fixed on the top of the pipe gallery 100. The bearing can rotate freely with the movement of the steel cable 1121. On the one hand, the driven wheel 1123 guides the steel cable 1121 to follow the track, avoiding the deviation of the steel cable 1121. On the other hand, a tensioning mechanism can be provided to adjust the position of the driven wheel 1123, so as to maintain the constant tension of the steel cable 1121 and prevent the power transmission failure caused by the relaxation of the steel cable 1121.

[0058] As shown in Figure 5 , the first cable pressing wheel 22 comprises a plurality of rollers rotatably connected to the main body 21 and arranged in sequence from front to back. The second cable pressing wheel 23 has the same structure as the first cable pressing wheel 22. In this embodiment, the second cable pressing wheel 23 and the first cable pressing wheel 22 are composed of a plurality of rollers arranged in sequence from front to back, which can be rotatably connected to the sliding block main body 21 through high-precision bearings. This arrangement changes the contact between the sliding block device 2 and the plate bearing track from a single point to multiple points, disperses the local pressure of the track caused by the weight of the goods, and avoids track deformation or roller wear caused by excessive force on a single point. At the same time, the synchronous rolling of multiple rollers can reduce the bumping and jamming during the movement of the sliding block, especially at the turning or joint of the track, which can achieve smooth transition through the sequential contact of the rollers, and improve the stability of the movement.

[0059] As shown in Figure 5 , the second limiter 25 comprises a limiting block 251 rotatably connected to the main body 21 through a rotating shaft, and an electrically controlled opening and closing device 252 connected to the limiting block 251 and used for controlling the rotation of the limiting block 251 around the rotating shaft. In this embodiment, the limiting block 251 is rotatably connected to the sliding block main body 21 through a rotating shaft, and can realize two states of closing and opening around the rotating shaft. When the electrically controlled opening and closing device 252 controls the block to close, the block and the sliding block main body 21 form a space surrounding the plate bearing main track 111, which limits the first cable pressing wheel 22 in the space to prevent the sliding block from deviating from the track during movement. When the block is opened, the opening forms a passage with the track, so that the first cable pressing wheel 22 can smoothly separate from the plate bearing main track 111, providing conditions for the sliding block to switch to the sub-track module 12.

[0060] In this embodiment, the electrically controlled opening and closing device 252 can be selected from, for example, an electromagnetic drive cylinder or an electric push rod, which is linked with the system intelligent controller. When the sliding block needs to continuously move on the main track, the controller sends a command to make the opening and closing device drive the block to close, maintaining the limiting state. When the sliding block reaches the sub-track transition section and needs to switch tracks, the controller receives the position signal, drives the opening and closing device to rotate the block around the rotating shaft to open, and realizes the unlocking.

[0061] In this embodiment, the first and second dismounting grip hangers 26 and 27 are mechanical dismounting grip hangers, and the main rail module 11 and each sub-rail module 12 are respectively provided with a separation frame for triggering the first and second dismounting grip hangers 26 and 27 to be mechanically dismounted and compressed.

[0062] It should be noted that the mechanical dismounting grip hanger is a common dismounting device of the existing cable car, which is prior art and generally includes a clamping mechanism and a triggering mechanism: the clamping mechanism generally includes a fixed jaw, a movable jaw, and a return spring, the fixed jaw is rigidly connected to the main body 21, the movable jaw is rotatably connected to the fixed jaw through a pin shaft, one end of the return spring is connected to the fixed jaw, and the other end is connected to the movable jaw, and the movable jaw is pulled to the fixed jaw by the spring tension in the normal state, so that the arc-shaped jaws of the two jaws tightly hold the traction cable 1121, forming a stable clamping state; the triggering mechanism includes a trigger rod and an unlocking cam, one end of the trigger rod extends outside the grip hanger, the other end is rigidly connected to the unlocking cam, and the unlocking cam is attached to the linkage part of the movable jaw, when the trigger rod is pushed by external force, the trigger rod is pressed down and pushes the movable jaw, overcoming the tension of the return spring, so that the movable jaw and the fixed jaw are separated, and the grip hanger and the cable 1121 are disconnected.

[0063] It should be noted that the separation frame provided in the present application is an external force pushing mechanism for triggering the clamping and unlocking of the first and second dismounting grip hangers 26 and 27, which is a triggering mechanism for realizing the disconnection of the grip hanger and the cable 1121, and the separation frame is in the form of a frame structure and is in the form of a U-shaped structure, including guide rails at both ends and a dismounting rail in the middle, when the unlocking cam at the end of the trigger rod on one side of the dismounting grip hanger first enters the guide rail of the separation frame, the grip hanger maintains a stable posture and moves to the dismounting rail, until it reaches the dismounting rail, the external force presses down and pushes the movable jaw through the trigger rod, overcoming the tension of the return spring, so that the movable jaw rotates around the pin shaft, the jaw gradually opens, the grip hanger and the traction cable 1121 are disconnected, and the power transmission is interrupted.

[0064] As Figure 2As shown, the separation frame includes a first entrance separation frame 291 and a second entrance separation frame 292 respectively located on the main rail module 11 and the sub-rail module 12 at the entrance of the ground entrance and exit system, and a first exit separation frame 293 and a second exit separation frame 294 respectively located on the main rail module 11 and the sub-rail module 12 at the exit of the ground entrance and exit system; the installation starting positions of the first entrance separation frame 291 and the second entrance separation frame 292 are the same, the installation length of the first entrance separation frame 291 covers the transition section to the sub-assembly section of the entrance, and the installation length of the second entrance separation frame 292 is located in the transition section; the installation starting positions of the first exit separation frame 293 and the second exit separation frame 294 are the same, and the installation length of the first exit separation frame 293 is smaller than that of the second exit separation frame.

[0065] It should be noted that the separation frame is divided into four categories according to the "entrance and exit direction" and the "corresponding rail module", each of which undertakes a specific stage of dismounting / resetting task to form a complete rail switching link; the first entrance separation frame 291 is arranged on the main rail module 11 at the entrance of the ground entrance and exit system 3, and the core function is to trigger the slider device 2 to loosen the cable type traction main cable 112 to prepare for entering the sub-rail module 12; the second entrance separation frame 292 is arranged on the sub-rail module 12 at the entrance of the ground entrance and exit system 3, and the core function is to trigger the slider device 2 to clamp the cable type traction sub-cable 122 while dismounting the main rail, so as to complete the switching of the power source from the main rail to the sub-rail; on the contrary, the first exit separation frame 293 and the second exit separation frame play the opposite switching role.

[0066] It should be noted that the starting end of the first inlet separation frame 291 is aligned with the second inlet separation frame 292, ensuring that the slider device 2 can simultaneously contact both types of separation frames when moving to the inlet, triggering the main rail separation frame to release at the same time as the sub-rail separation frame triggers clamping, avoiding power interruption or switching delay; the first inlet separation frame 291 has a length covering the transition section and the sub-packaging section, because after the slider enters the sub-rail from the main rail, it needs to move along the transition section to the sub-packaging section to reach the cargo loading and unloading area of the ground access cargo system 3, the longer first inlet separation frame 291 can ensure that the first release grip 26 always remains in a released state when the slider device 2 turns into the sub-packaging section, so that the slider device 2 can smoothly turn into the sub-rail module 12 without being affected by the cable traction main cable 112 while the second release grip 27 clamps the cable traction sub-cable 122; while the second inlet separation frame 292 has a length only in the transition section, because the clamping action of the second release grip 27 on the cable traction sub-cable 122 needs to be completed before entering the sub-packaging section. The starting end of the first outlet separation frame 293 is aligned with the second outlet separation frame, ensuring that the slider can simultaneously contact both types of separation frames when returning from the sub-packaging section to the transition section, achieving synchronous operation of releasing the sub-rail and clamping the main rail; the second outlet separation frame has a length greater than the first outlet separation frame 293, because when the slider returns from the sub-rail to the main rail, the sub-rail separation frame needs to first continuously guide the slider device 2 to release the sub-rail, then give the main rail separation frame enough time to trigger the main rail clamping, and the second release grip 27 always remains in a released state, so that the slider device 2 can smoothly turn into the main rail module 11 without being affected by the cable traction sub-cable 122 while the first release grip 26 clamps the cable traction main cable 112.

[0067] As shown in Figure 1 The ground access cargo system 3 includes a ground well 31 for connecting the space above ground and the underground pipe gallery 100, an elevator 32 arranged in the ground well 31, and a conveyor belt device 33 extending to one end of the elevator 32, and the other end of the conveyor belt device 33 extending below the sub-packaging section of the plate-type bearing sub-rail 121.

[0068] In this embodiment, the ground well 31 is a rigid passage connecting the ground above and the underground pipe gallery 100, usually a square or circular shaft of concrete or metal material, and its core function is to break through the physical isolation between the top of the pipe gallery 100 and the ground. The size of the ground well 31 needs to adapt to the lifting space of the elevator 32 and the installation requirements of the conveyor belt device 33, and the inner wall of the shaft will be provided with protective structures such as anti-falling guardrails and wear-resistant lining plates.

[0069] In this embodiment, the elevator 32 is arranged inside the ground well 31, and its essence is a small guide rail type lifting platform composed of guide rails, lifting platforms, drive motors and safety locks, which can be applied by using existing technical equipment. The core function of the elevator 32 is to receive the goods transported by the conveyor belt.

[0070] In this embodiment, the conveyor belt device 33 is a horizontal bridge connecting the split rail and packaging section and the elevator 32, which is composed of a conveyor belt, a driving roller and a support bracket, and can be applied by using existing technical equipment.

[0071] It should be noted that the top of the pipe gallery 100 and the space of the well 31 are relatively narrow, and traditional large vertical transportation equipment cannot be installed. The design of the components of the system considers space adaptability.

[0072] It should be noted that the connection between the well 31 and the pipe gallery 100 can reserve space for loading or unloading operations.

[0073] Further, the connector 28 is an automatic unhooker.

[0074] It should be noted that the automatic unhooker is generally composed of a hook assembly, a trigger mechanism, a reset spring and an electric control sensor, and can be applied by using existing technical equipment. The automatic unhooker is installed at the lower part of the main body 21 of the sliding block device 2.

[0075] The advantage of the present application is that the existing scheme focuses on the bottom of the pipe gallery 100, which not only occupies the operation and maintenance channel, but also has the problem of low space utilization. The transportation track is built in the idle space of the top of the pipe gallery 100, which does not affect the original operation and maintenance operation at the bottom of the pipe gallery 100, realizes the "three-dimensional utilization" of the space of the pipe gallery 100, relies on the top space of the existing pipe gallery 100, and does not need to occupy additional land or build a new ground logistics channel, which greatly reduces the construction cost of urban logistics infrastructure. The automatic operation mode reduces labor costs, and the mechanical structure of the overhead rail system 1 and the sliding block device 2 is simple to maintain, and the operation and maintenance cost is much lower than that of the traditional manual logistics distribution mode; the intelligent scheduling system can be used to link the sub-systems of the present application, adapt to the logistics scene of the "last mile" of the city, realize rapid transfer and delivery of goods, and form an integrated logistics operation system.

[0076] Embodiment 2 This embodiment is similar to embodiment 1, except that in this embodiment: As shown in Figure 1 and Figure 6 The pipe gallery top space logistics transportation system further comprises a logistics box 4, the logistics box 4 is connected with the connector 28, and the top of the logistics box 4 is provided with a lifting ring. By setting a standard logistics box 4 as a standardized carrying container for goods, the risk of collision, friction and moisture during multi-link transfer of the goods can be reduced; the lifting ring is used as a connection interface between the logistics box 4 and the automatic unhooker, and is fixed at the center position of the top of the logistics box 4. The structure is designed to accurately match the hook assembly of the automatic unhooker.

[0077] Embodiment 3 This embodiment is similar to embodiment 1, except that in this embodiment As Figure 7 shown, the pipe gallery internal overhead space logistics transportation system further comprises a control system 5 connected to the overhead monorail system 1, the sliding block device 2 and the ground access system 3 respectively.

[0078] As Figure 7 shown, the pipe gallery internal overhead space logistics transportation system further comprises a plurality of code scanners 6 for identifying goods, the code scanners 6 being connected to the control system 5 and arranged at positions of the overhead monorail system 1 and / or the ground access system 3.

[0079] It should be noted that the addition of the control system 5 and the code scanners 6 is the core support for the pipe gallery 100 logistics system to move from mechanical automation to intelligent informationization, and the two work together to realize full-link intelligent scheduling of goods tracking, equipment linkage and process control.

[0080] In this embodiment, the code scanners 6 cooperate with the existing two-dimensional code / bar code system for identification, and existing technical devices can be used for application.

[0081] In this embodiment, the control system 5 as the central brain of the pipe gallery 100 logistics can adopt PLC and Internet of Things architecture, and is connected in real time with sensors and actuators of the overhead monorail system 1, the sliding block device 2 and the ground access system 3 through a data bus; wherein the control system 5 collects key data through various sensors: As Figure 7 shown, in the overhead monorail system 1, a motor current sensor 61 and a steel cable tension sensor 62 are arranged to monitor the running load of the main rail driving device and the tension of the steel cable; As Figure 7 shown, in the sliding block device 2, a position sensor 63 is arranged to obtain real-time coordinates of the sliding block, a pressure sensor 64 is arranged to detect the engagement force between the automatic unhooking device and the lifting ring, and a speed sensor 65 is arranged to monitor the sliding block movement speed; As Figure 7 shown, in the ground access system 3, a displacement sensor 66 is arranged on the elevator 32 to obtain the height of the lifting platform, a photoelectric sensor 67 is additionally arranged on the conveyor belt device 33 to detect whether the logistics box 4 is in place, and a weight sensor 68 is arranged to judge the load of the logistics box 4 to avoid overload; all data are transmitted in real time to the control system 5 through the Internet of Things module; The preset program and algorithm in the control system 5 are built-in, logical judgment is made according to the collected data, and instructions are issued to perform normal logistics scheduling: when the code scanner 6 identifies the information of the logistics box 4, such as the destination track number, the control system 5 automatically plans the transportation path of the slider device 2, such as transferring goods from a certain track to another track through the main track, synchronously instructing the hoist track system 1 to adjust the speed of the corresponding steel cable 1121, instructing the slider device 2 to complete the unhooking / hooking at the specified position, and instructing the ground in-out system 3 to coordinate the start and stop of the elevator 32 and the conveyor belt; at the same time, the control system 5 can also monitor the abnormal alarm of each system: if the steel cable tension sensor 62 detects abnormal tension, the control system 5 immediately instructs the drive device to stop, and at the same time sends a warning through the alarm module; if the slider position sensor 63 detects deviation, instruct the slider to adjust the direction to avoid collision with the track; if the weight of the logistics box 4 is overloaded, instruct the elevator 32 to stop rising and wait for manual processing. The control system 5 converts control instructions into device actions through relays, frequency converters and other execution components: such as instructing the electromagnetic push rod of the automatic unhooking device to be powered on to achieve the opening of the double hooks; instructing the drive motor of the elevator 32 to rotate forward to drive the lifting platform to rise; instructing the main track drive device to adjust the frequency to change the movement speed of the steel cable 1121, to ensure the precise synchronization of each device action, etc.

[0082] Obviously, the above embodiments of the application are merely exemplary and are not intended to limit the implementation modes of the application. Based on the above description, those skilled in the art can make other different forms of changes or modifications. It is not necessary or possible to exhaust all the implementation modes. Any modification, equivalent replacement and improvement made within the spirit and principle of the application shall be included in the protection scope of the claims of the application.
