Description

Technical Field

[0001] The present invention relates to the technical field of logistics transmission, and in particular to a rail trolley, a use method and a logistics system. Background Art

[0002] The rail trolleys commonly used in hospital logistics have horizontal tracks suspended below the corridor ceiling, which is convenient for later maintenance and does not occupy the space in the ceiling. It is an ideal installation method. The overall structure of the rail trolley affects the hospital logistics system, so the structure of the rail trolley is constantly optimized. For example,

[0003] 1. A Chinese patent with an application date of 2020.06.16, publication number CN111792299A, and invention name “A Logistics System for Hospitals” discloses a technical solution that cancels the conventional box structure for transfer and replaces it with a box separated from the vehicle body, so that the vehicle body has its own hooks, which are used to mount (including mounting external devices or turnover boxes). However, when the box is actually used, its hooks extend from both sides of the vehicle body and are hidden in the track, so that the track cannot be made very thin and must occupy the space in the corridor ceiling. This makes it difficult to install logistics equipment and the current situation of the incompatibility between logistics equipment and the hospital environment has not been fundamentally changed;

[0004] 2. The Chinese patent with application date of 2017.01.12, publication number of CN206761989U, and invention name of “A medical track-type infusion stand” discloses a hook structure that is arranged in the center of the track and extends vertically downward and can rotate 90 degrees around the vertical axis to solve the problem of positioning or free movement on the track. However, if this structure is used to mount and transport turnover boxes, not only will there be the old problems of large overall size of the equipment and incompatibility of appearance with the environment, but also the potential safety hazard of unstable mounting.

[0005] Therefore, in order to solve the problems existing in the existing technology, our company has carried out corresponding research and development. Summary of the invention

[0006] The main purpose of the present invention is to solve the problems existing in the prior art and to provide a rail trolley, a method of use and a logistics system with a novel structure, small space occupation, and the ability to meet the needs of various specifications of mounting, the track can be covered, the overall quality is light and thin, and the appearance is straight and neat.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is: a rail trolley, wherein the rail trolley includes a track, a vehicle body that runs on the track, a cover plate that covers the track and the vehicle body on the inside, and a hook that is driven by a rotating mechanism arranged on the vehicle body to rotate vertically or retract horizontally to the inside of the cover plate, and the hooks are arranged in two groups corresponding to the running direction of the vehicle body, and a mounting area is formed between the two groups.

[0008] By adopting the above technical solution, the vehicle body is separated from the box body and mounted by the hook. Since the hook can be rotated to extend vertically or retract horizontally to the inside of the cover plate, the vertical space occupied by the hook is reduced, and the track can be covered by the cover plate and integrated with the ceiling, so as to ensure that the appearance of the track is straight and neat when the hook is fully retracted to the inside of the cover plate. At the same time, the hook is arranged along the traveling direction of the vehicle body, which further reduces the space occupied, thereby making the supporting technology formed by the track and the vehicle body lighter and thinner.

[0009] Furthermore, the cover plate includes an opening and closing section for covering the rotation path of the hook, and a covering section which is arranged on the track and the outside of the vehicle body and guides the movement of the hook.

[0010] By adopting the above technical solution, the hook can be rotated in the opening and closing section to vertically extend or horizontally retract into the inner side of the cover plate to achieve its state switching, and the covering section can cover the track and the car body without affecting the normal movement of the hook, making the overall structure of the rail trolley beautiful.

[0011] Furthermore, the opening and closing section includes a movable sliding door. When the movable sliding door is opened, the hook is rotated to vertically extend or horizontally retract to the inner side of the cover plate.

[0012] Furthermore, a pushing mechanism drives the movable sliding door to open and close.

[0013] By adopting the above technical solution, the movable sliding door of the opening and closing section provides an action area for switching the hook state, which has a simple structure and is easy to operate.

[0014] Furthermore, the opening and closing section is also provided with a power supply device for the rotating mechanism, and the vehicle body is provided with a power connection device, and the power supply device is driven by the moving mechanism to contact or disconnect the power connection device to supply power to or cut off power to the rotating mechanism.

[0015] By adopting the above technical solution, power can be distributed to the rotating mechanism only when it is working. Firstly, the mechanical structure is simplified, and secondly, energy can be effectively saved and costs can be reduced.

[0016] Furthermore, the covering section includes two groups of L-shaped gussets correspondingly covering the track and the outside of the vehicle body. The two groups of L-shaped gussets are arranged along the traveling direction of the vehicle body. Both ends are fixed to the installation position of the track trolley, and a hook is formed between the ends to extend out of the center seam.

[0017] Furthermore, the structure of the middle seam matches the structure of the hook.

[0018] By adopting the above technical solution, two groups of L-shaped gusset plates form a structure that covers the track and the car body from both sides to the middle, which is easy to disassemble and maintain, simple and practical.

[0019] Furthermore, a travel drive drives the vehicle body to travel on the track.

[0020] Furthermore, the rotating mechanism includes a motor and a coupling, one end of the coupling is connected to the motor shaft output end of the motor, and the other end of the coupling is connected to the hook input end.

[0021] Furthermore, the hook includes a connecting plate driven to rotate by a rotating mechanism, a side panel connected to the lower part of the connecting plate, and a bottom plate extending from the side panel, and the side panel and the bottom plate cooperate to form a mounting structure.

[0022] Furthermore, the length of the side panel is greater than that of the connecting panel, and its length away from the connecting point of the two gradually increases.

[0023] By adopting the above technical solution, it is ensured that when the side panels and the bottom plate are mounted, the contact surface between the mounted device or turnover box is large and the mounting is stable.

[0024] Furthermore, when viewed along the traveling direction of the vehicle body, the hook is in an inverted T shape, and when viewed perpendicularly to the traveling direction of the vehicle body, the hook is in an L shape.

[0025] By adopting the above technical solution, the mounting stability is ensured and the hook size can be made smaller to ensure the covering effect of the cover plate on the track and the vehicle body.

[0026] Furthermore, when the two groups of hooks switch between vertical extension and horizontal retraction in the opening and closing section, the interval between the two groups is the largest.

[0027] By adopting the above technical solution, the size specification that can be mounted when the two sets of hooks are in this position state is the largest.

[0028] Furthermore, it also includes a spacing adjustment mechanism, which is used to change the interval between the two groups of hooks to match the mounting of corresponding specifications.

[0029] By adopting the above technical solution, the working performance of the rail trolley is optimized, so that its hook carrier can meet the clamping requirements of various specifications of mountings (including external devices or turnover boxes), and has strong applicability.

[0030] Furthermore, the spacing adjustment mechanism includes an electric push rod arranged on the vehicle body, and the electric push rod drives the rotating mechanisms of the two groups of hooks to move synchronously toward each other through the traction mechanism to adjust the spacing between the two groups of hooks.

[0031] By adopting the above technical solution, the two sets of hooks can move synchronously, which shortens the time for hook mounting and ensures the working efficiency of the rail trolley.

[0032] Furthermore, the traction mechanism includes a guide rail located on the vehicle body, two groups of moving components driven by an electric push rod to slide on the guide rail, and a pulling component used to pull the two groups of moving components to move toward each other, and the moving components are connected to the rotating mechanism.

[0033] Furthermore, the pulling assembly includes a pulley arranged on the vehicle body, and an annular synchronous belt arranged between two sets of pulleys. The upper belt and the lower belt of the annular synchronous belt are respectively connected to a set of moving components through tooth plates, and the two sets of moving components are pulled by the annular synchronous belt to move synchronously toward each other.

[0034] By adopting the above technical solution, the two sets of hooks on the vehicle body can move synchronously towards each other, which is simple and practical.

[0035] Furthermore, a force-applying component is connected to the spacing adjustment mechanism, and the force-applying component transmits the clamping force to the hook, and the hook applies the clamping force to the mount.

[0036] Furthermore, the force-applying component is connected between the electric push rod and the moving component, and the force-applying component transmits the clamping force to the hook through the moving component.

[0037] By adopting the above technical solution, reliable and stable mounting between the two sets of hooks is ensured, and the hook mounting working performance is further optimized. At the same time, the design of connecting the force-adding component between the electric push rod and the traction mechanism also makes the overall structure of the rail trolley compact and can reduce its size specifications.

[0038] Furthermore, the force-applying component includes a steel pipe connected to the output end of the electric push rod, and a tension spring located in the inner cavity of the steel pipe and one end of which is fixed to the steel pipe by a limit bolt. The other end of the tension spring is fixed to the traction mechanism, and its length in a free state is less than the length of the steel pipe, so that the tension spring has a pre-tensioning force.

[0039] Furthermore, the other end of the tension spring is fixed to a group of moving components in the traction mechanism.

[0040] By adopting the above technical solution, the electric push rod can apply force to the moving component through the tension spring, and the moving component transmits the clamping force to the hook, thereby ensuring the clamping reliability of the hook on the mounting.

[0041] Furthermore, a position sensor is included, which detects and feeds back the movement information of the end of the tension spring to the control system of the rail trolley to control the working state of the electric push rod.

[0042] Through the above technical solution, the position sensor can detect and provide feedback on the moving distance of the end of the tension spring, thereby preventing damage to the mount caused by excessive hook tension.

[0043] A method for using the above-mentioned rail trolley, wherein the method for using is:

[0044] S1, the rotating mechanism drives the hook to extend vertically from the inner side of the cover plate;

[0045] S2. Place the mount between the two sets of hooks;

[0046] S3, making the vehicle body move on the track for transportation and mounting;

[0047] S4. After the transfer is completed, the rotating mechanism drives the hook to retract horizontally to the inside of the cover plate.

[0048] By adopting the above method, the hook used for mounting can be hidden in the cover plate, which realizes the convenient transportation of the vehicle body to the mounting and further ensures the aesthetics of the overall structure of the rail trolley.

[0049] Furthermore, the process of the hook rotating to vertically extend or horizontally retract to the inner side of the cover plate is as follows:

[0050] a. Make the vehicle body move along the track until it is located in the opening and closing section as a whole;

[0051] b. Open the movable sliding door of the opening and closing section to expose the hook rotation path area;

[0052] c. The hook is driven by the rotating mechanism to rotate and extend vertically or retract horizontally to the inner side of the cover plate at the movable sliding door;

[0053] d. Close the movable sliding door to cover the hook rotation path.

[0054] Furthermore, the method includes the steps of: adjusting the distance between the two groups of hooks by a distance adjustment mechanism; when this step is performed after step S1, it can match the mounting of corresponding specifications; and when this step is performed after step S3, it can maximize the distance between the two groups of hooks to prepare for the horizontal retraction of the hooks.

[0055] Furthermore, the specific process of adjusting the distance between the two groups of hooks is that the electric push rod stretches or pushes the tension spring, and the tension spring drives one group of moving components to slide along the guide rail. With the assistance of the pulling component, the other group of moving components will move synchronously towards each other. At this time, the rotating mechanism moves with the moving component, and the traction hook moves accordingly, thereby completing the adjustment of the distance between the two.

[0056] Furthermore, the method further comprises the step of applying a clamping force to the two groups of hooks by a force-applying component, which step is after step S2.

[0057] Furthermore, the specific process of the force-applying component applying the clamping force to the two groups of hooks is that when the hooks are pressed against the mount under the traction of the electric push rod and the moving component, the hooks stop moving, so that the electric push rod continues to stretch the tension spring until the tension value of the tension spring reaches the set value of the position sensor, thereby controlling the electric push rod to stop working.

[0058] Through the above technical solution, when the electric push rod continues to stretch the tension spring, the elastic restoring force of the tension spring is further increased, and is transmitted to the hook through the moving component and the rotating mechanism, and the hook clamps the mount. At the same time, the position sensor detects the movement information of the end of the tension spring and feeds back to the control system of the rail trolley. When the moving distance of the end of the tension spring reaches the set value (that is, the tension reaches the set value of the position sensor), the control system controls the electric push rod to stop working and completes the clamping operation of the mount.

[0059] Furthermore, the vehicle body is driven by a travel drive to move on the track. At this time, if the hook extends vertically out of the inner side of the cover plate, its connecting plate moves along the center seam, and the side panel and the bottom plate move with the mounting or vacancy. Otherwise, the hook is horizontally retracted inside the cover plate and moves with the vehicle body.

[0060] Furthermore, the movable sliding door is driven to open and close by a driving mechanism.

[0061] Furthermore, in the above step c, the specific action process of the hook is:

[0062] i. The mobile mechanism drives the power supply device to move to contact with the power receiving device on the vehicle body to distribute power to the rotating mechanism;

[0063] ii. The rotating mechanism rotates, and the hook rotates from a horizontal state to a vertical state and extends out of the inner side of the cover plate for mounting, or rotates from a vertical state to a horizontal state and retracts into the inner side of the cover plate to prepare for the next mounting;

[0064] iii. The moving mechanism drives the power supply device to move to be separated from the power supply device on the vehicle body, and the rotating mechanism is powered off, thereby completing an extension or retraction action of the hook from the inner side of the cover plate.

[0065] A logistics system, wherein the logistics system includes the above-mentioned rail trolley.

[0066] Furthermore, the logistics system also includes a site, and the site is located in a logistics transfer area.

[0067] Furthermore, the opening and closing section in the rail trolley is arranged at the station.

[0068] The advantages and positive effects of the present invention are:

[0069] (1) By separating the vehicle body from the box body and mounting it with a hook, and because the hook can be rotated to extend vertically or retract horizontally into the inner side of the cover plate, the vertical space occupied by the hook is reduced, and the track can be covered by the cover plate and integrated with the ceiling, so that when the hook is fully retracted into the inner side of the cover plate, the appearance of the track is straight and neat. At the same time, the hook is arranged along the direction of travel of the vehicle body, which further reduces the space occupied, thereby making the supporting technology formed by the track and the vehicle body lighter and thinner.

[0070] (2) The hook can be rotated in the opening and closing section to extend vertically or retract horizontally into the inner side of the cover plate to switch its state, and the cover section can cover the track and the car body without affecting the normal movement of the hook, so that the overall structure of the rail trolley is beautiful.

[0071] (3) The working performance of the rail trolley is optimized through the spacing adjustment mechanism, so that its hook carrier can meet the clamping requirements of various specifications of mounts (including external devices or turnover boxes), and has strong applicability.

[0072] (4) The force-adding assembly ensures reliable and stable mounting between the two sets of hooks, and its design of connecting the electric push rod and the traction mechanism also makes the overall structure of the rail trolley compact, which can reduce its size specifications.

DETAILED DESCRIPTION

[0083] In order to better understand the present invention, the present invention is further described below in conjunction with specific embodiments and drawings.

[0084] Embodiment 1

[0085] like Figure 1-Figure 5 As shown, a rail trolley comprises a rail 1, a vehicle body 2 that runs on the rail 1, a cover plate 3 that covers the rail 1 and the vehicle body 2 on the inner side, and a hook 5 that is rotated by a rotating mechanism 4 arranged on the vehicle body 2 and vertically extends or horizontally retracts into the inner side of the cover plate 3. The hooks 5 are arranged in two groups corresponding to each other along the running direction of the vehicle body 2, and a mounting area 6 is formed between the two groups.

[0086] Specifically, a receiving area 21 for the hook 5 is provided on the vehicle body 2, and the structure of the receiving area matches the structure of the hook 5. When the hook 5 is retracted to the inner side of the cover plate 3 along with the rotating mechanism 4, it can be horizontally located in the receiving area 21. The two groups of hooks 5 are arranged at the two ends of the vehicle body 2 correspondingly and arranged along the moving direction of the vehicle body 2, occupying the smallest space. Compared with the arrangement of the two groups of hooks 5 along the moving direction perpendicular to the vehicle body 2, in order to realize the normal mounting of the turnover box and other devices by the hook 5, it is necessary to ensure that the spacing between the two groups of hooks 5 matches the turnover box. The larger the size of the turnover box, the larger the spacing between the two groups of hooks 5. If the two groups of hooks 5 are arranged along the direction perpendicular to the travel of the vehicle body 2, then a gap of sufficient width must be reserved on the cover plate 3 so that the two groups of hooks 5 can extend normally and move with the vehicle body 2. In this case, the coverage rate of the cover plate 3 on the track 1 and the vehicle body 2 will be reduced, thereby reducing the actual effectiveness of the entire technical solution. If the two groups of hooks 5 are arranged along the direction of travel of the vehicle body 2, there is no problem of the spacing between the hooks 5 affecting the width of the reserved gap of the cover plate 3.

[0087] Of course, if two groups of hooks 5 are arranged along the direction perpendicular to the movement of the vehicle body 2, in order to avoid the influence of the spacing between the hooks 5 on the reserved gap of the cover plate 3, the hooks 5 can be mounted instead of being directly used. Instead, a corresponding frame can be set on it and the mounting is performed by the frame. The hooks 5 only serve as an intermediate connecting component connecting the vehicle body 2 and the frame, that is, the spacing between the hooks 5 can be determined according to the reserved gap of the cover plate 3, and the frame is hung between the hooks 5. The frame is designed to be a structure that can match the corresponding specifications of mounting and will not be expanded or extended here.

[0088] Furthermore, the cover plate 3 includes an opening and closing section for covering the rotation path of the hook 5, and a covering section that is arranged outside the track 1 and the vehicle body 2 and guides the movement of the hook 5 (only the covering section of the cover plate 3 is shown in the figure).

[0089] Furthermore, the opening and closing section includes a movable sliding door (not shown in the figure). When the movable sliding door is opened, the hook 5 rotates to vertically extend or horizontally retract to the inner side of the cover plate 3.

[0090] Furthermore, a driving mechanism drives the movable sliding door to open and close.

[0091] Specifically, the pushing mechanism may adopt a telescopic cylinder, which drives the movable sliding door to move open or close by extending and retracting the telescopic cylinder. Other mechanical structures that can realize the opening or closing of the movable sliding door may also be adopted.

[0092] Furthermore, a power supply device is provided for the rotating mechanism 4 in the opening and closing section, and a power receiving device is provided on the vehicle body 2. The power supply device is driven by the moving mechanism to contact or disconnect the power receiving device to supply power to or cut off power to the rotating mechanism 4 (not shown in the figure).

[0093] Specifically, the specific structure, working principle and control method between the power supply device, the power receiving device and the mobile mechanism can adopt the existing technology. This application does not make any improvements on this, so it will not be described in detail.

[0094] Furthermore, the covering section includes two groups of L-shaped gusset plates 31 correspondingly covered on the outside of the track 1 and the vehicle body 2. The two groups of L-shaped gusset plates 31 are arranged along the traveling direction of the vehicle body 2. Both ends are fixed to the installation position of the track trolley, and a hook 5 is formed between the ends to extend out of the middle seam 32.

[0095] Furthermore, the structure of the middle seam 32 matches the structure of the hook 5 .

[0096] Specifically, the starting ends of the two groups of L-shaped gusset plates 31 are fixed on the ceiling. The covering section formed by the two groups of L-shaped gusset plates 31 not only ensures the covering of the track 1 and the vehicle body 2, but also can conveniently form a center gap 32 for the hook 5 to extend by adjusting the distance between the two. When one of them is damaged, only the corresponding one needs to be replaced, which ensures the service life of the L-shaped gusset plates 31 and reduces the production cost. The overall structure is simple, the replaceability is strong, and the installation and adjustment are convenient.

[0097] Furthermore, the vehicle body 2 is driven by a travel drive 7 to travel on the track 1 .

[0098] Specifically, the travel drive 7 is based on enabling the vehicle body 2 to travel on the track 1 , and its specific structure and working principle can adopt the existing technology in the field.

[0099] Furthermore, the rotating mechanism 4 includes a motor and a coupling, one end of the coupling is connected to the motor shaft output end of the motor, and the other end of the coupling is connected to the input end of the hook 5.

[0100] like Figure 6 As shown, further, the hook 5 includes a connecting plate 51 driven to rotate by the rotating mechanism 4, a side panel 52 connected to the lower part of the connecting plate 51, and a bottom plate 53 extending from the side panel 52, and the side panel 52 and the bottom plate 53 cooperate to form a mounting structure.

[0101] Specifically, the length of the connecting plate 51 is smaller than the width of the center seam 32 to ensure that the hook 5 moves normally along the center seam 32. A rotating shaft is connected to the connecting plate 51 to form an input end of the hook 5. The connecting plate 51 is driven to rotate by the rotating mechanism 4 through the rotating shaft, so that the side panel 52 and the bottom plate 53 can switch between a horizontal state and a vertical state to retract or extend the inner side of the cover plate 3. In addition, the top end of the side panel 52 can be fixed to the lower end of the connecting plate 51, and it and the bottom plate 53 can be formed as one piece.

[0102] Furthermore, the length of the side panel 52 is greater than that of the connecting panel 51 , and its length away from the connecting point of the two gradually increases.

[0103] Specifically, the side panel 52 can be integrally formed by an upper plate body and a lower plate body. The upper plate body is connected to the lower part of the connecting plate 51, and its cross-section is a trapezoid that is small at the top and large at the bottom. The cross-section of the lower plate body is rectangular, and its length is greater than the upper plate body. The length of the bottom plate 53 is equal to the length of the lower plate body.

[0104] Furthermore, when viewed along the traveling direction of the vehicle body 2 , the hook 5 is in an inverted T-shape, and when viewed perpendicularly to the traveling direction of the vehicle body 2 , the hook 5 is in an L-shape.

[0105] Embodiment 2

[0106] like Figure 7-Figure 9As shown, the difference from the first embodiment is that, further, when the two sets of hooks 5 switch between vertical extension or horizontal retraction in the opening and closing section, the interval between the two sets of hooks is the largest.

[0107] Specifically, at this time, the interval between the two is larger than the size of the maximum mount (including external devices or turnover boxes).

[0108] Furthermore, a spacing adjustment mechanism 8 is included, and the spacing adjustment mechanism 8 is used to change the interval between the two groups of hooks 5 to match the mounting of corresponding specifications.

[0109] Furthermore, the spacing adjustment mechanism 8 includes an electric push rod 81 disposed on the vehicle body 2 , and the electric push rod 81 drives the rotating mechanisms 4 of the two groups of hooks 5 to move synchronously toward each other through the traction mechanism 82 , thereby adjusting the spacing between the two groups of hooks 5 .

[0110] Furthermore, the traction mechanism 82 includes a guide rail 821 located on the vehicle body 2, two groups of moving components 822 driven by the electric push rod 81 to slide on the guide rail 821, and a pulling component 823 for pulling the two groups of moving components 822 to move toward each other. The moving components 822 are connected to the rotating mechanism 4.

[0111] Furthermore, the pulling component 823 includes a pulley 8231 arranged on the vehicle body 2, and an annular synchronous belt 8232 arranged between two sets of pulleys 8231. The upper belt and the lower belt of the annular synchronous belt 8232 are respectively connected to a set of moving components 822 through tooth plates 8233, and the two sets of moving components 822 are pulled by the annular synchronous belt 8232 to move synchronously toward each other.

[0112] Specifically, two groups of guide rails 821 are arranged correspondingly on the vehicle body 2; the moving component 822 includes a connecting plate, two groups of mounting seats correspondingly located at the bottom of the connecting plate, and a slider fixed at the bottom of the mounting seat, the sliders cooperate to slide along the guide rail 821, and the mounting seat is connected to the rotating mechanism 4, the tooth plate 8233 is fixed on a group of mounting seats, and is connected to the annular synchronous belt 8232 next to the guide rail 821.

[0113] In addition, the mechanical structure used to drive the two groups of hooks 5 to move synchronously toward each other is not limited to the above-mentioned scheme adopted in the present application. Any other mechanical structure that can realize the synchronous movement of the two groups of hooks 5 toward each other should also be covered under the protection scope of the present application. Of course, the two groups of hooks 5 can also move asynchronously toward each other. However, the above-mentioned scheme is one of the preferred methods after comprehensively considering aspects such as work efficiency, production cost and the overall weight of the rail trolley.

[0114] Embodiment 3

[0115] like Figure 7-Figure 9As shown, the difference from the first and second embodiments is that, further, a force component 9 is connected between the electric push rod 81 and the moving component 822, and the force component 9 transmits the clamping force to the hook 5 through the moving component 822, and the hook 5 applies the clamping force to the mounting.

[0116] Preferably, in order to ensure the clamping stability of the rail trolley on the mounting, the hook 5 can apply a predetermined clamping force to the mounting, that is, a clamping force value range is pre-set. When mounted by the hook, the clamping force applied by the force application component is controlled to reach the set range, thereby making the rail trolley mounting stable.

[0117] Furthermore, the force-applying component 9 includes a steel tube 91 connected to the output end of the electric push rod 81, and a tension spring 92 located in the inner cavity of the steel tube 91 and one end of which is fixed to the steel tube 91 by a limit bolt. The other end of the tension spring 92 is fixed to the traction mechanism 82, and its length in a free state is less than the length of the steel tube 91, so that the tension spring 92 has a pre-tensioning force.

[0118] Specifically, one end of the tension spring 92 away from the electric push rod 81 is connected to the connecting plate in the moving component 822 through a connecting rod. Because the tension spring 92 is fixed on the steel pipe 91 in a stretched state, the tension spring 92 has a pre-tensioning force when the electric push rod 81 is not moving.

[0119] In addition, the design of the force-applying component, firstly, eliminates the gap between the tension spring 92 and the electric push rod 81, so that the electric push rod 81 can accurately move the hook 5, and secondly, reduces the stroke of the electric push rod 81 that applies force to the hook 5, so that the clamping force does not start from zero, but starts from a predetermined value. When the electric push rod 81 is in motion, the moving component 822 can drive the hook 5 to move, and after the hook 5 is against the mount, the electric push rod 81 can continue to stretch the tension spring 92 to apply a greater clamping force to the hook 5 to ensure the clamping reliability of the mount.

[0120] Furthermore, a position sensor is included, which detects and feeds back the movement information of the end of the tension spring 92 to the control system of the rail trolley to control the working state of the electric push rod 81.

[0121] In addition, the specific models and specifications of the motor, electric push rod 81, and position sensor need to be determined by selection calculation based on the specification parameters of the rail trolley and the specification range of the transported load. The selection calculation method is the existing technology. The driving mechanism, moving mechanism, walking drive, motor, electric push rod 81 and position sensor are electrically connected to the control system of the rail trolley. The specific electrical connection structure, connection method and control principle between the above-mentioned electrical components and the control system are the existing technology. This application has not made any improvements to this, so it will not be described in detail.

[0122] Embodiment 4

[0123] like Figure 1-Figure 9 As shown, a method for using the rail trolley according to embodiments 1 to 3, wherein the method of use is:

[0124] S1, the hook 5 is driven by the rotating mechanism 4 to extend vertically from the inner side of the cover plate 3;

[0125] S2, placing the mount between the two sets of hooks 5;

[0126] S3, making the vehicle body 2 move on the track 1 for transportation and mounting;

[0127] S4, after the transfer is completed, the rotating mechanism 4 drives the hook 5 to retract horizontally to the inner side of the cover plate 3.

[0128] Furthermore, the process of the hook 5 rotating to vertically extend or horizontally retract to the inner side of the cover plate 3 is as follows:

[0129] a. Make the vehicle body 2 move along the track 1 until the vehicle body 2 is located in the opening and closing section;

[0130] b. Open the movable sliding door of the opening and closing section to expose the rotation path area of ​​the hook 5;

[0131] c. The hook 5 is driven by the rotating mechanism 4 to rotate, and is vertically extended or horizontally retracted to the inner side of the cover plate 3 at the movable sliding door;

[0132] d. Close the movable sliding door to cover the rotation path of hook 5.

[0133] Furthermore, the method includes the steps of: adjusting the distance between the two groups of hooks 5 by the distance adjustment mechanism 8; when this step is performed after step S1, it can match the mounting of corresponding specifications; and when this step is performed after step S3, it can maximize the distance between the two groups of hooks 5 to prepare for the horizontal retraction of the hooks 5.

[0134] Furthermore, the specific process of adjusting the distance between the two groups of hooks 5 is that the electric push rod 81 stretches or pushes the tension spring 92, and the tension spring 92 drives one group of moving components 822 to slide along the guide rail 821. With the assistance of the pulling component 823, the other group of moving components 822 will move synchronously towards each other. At this time, the rotating mechanism 4 moves with the moving component 822, and the traction hook 5 moves accordingly, thereby completing the adjustment of the distance between the two.

[0135] Furthermore, the method further comprises the step of applying a clamping force to the two groups of hooks 5 by the force applying component 9, which step is after step S2.

[0136] Furthermore, the specific process of the force-applying component 9 applying the clamping force to the two groups of hooks 5 is that when the hooks 5 are pressed against the mount under the traction of the electric push rod 81 and the moving component 822, the hooks 5 stop moving, so that the electric push rod 81 continues to stretch the tension spring 92 until the tension value of the tension spring 92 reaches the set value of the position sensor, thereby controlling the electric push rod 81 to stop working.

[0137] Furthermore, the vehicle body 2 is driven by the travel drive 7 to move on the track 1. At this time, if the hook 5 extends vertically out of the inner side of the cover plate 3, its connecting plate 51 moves along the middle seam 32, and the side panel 52 and the bottom plate 53 are mounted and move with it or are empty and move with it. Otherwise, the hook 5 is horizontally retracted inside the cover plate 3 and moves with the vehicle body 2.

[0138] Furthermore, the movable sliding door is driven to open and close by a driving mechanism.

[0139] Furthermore, in the above step c, the specific action process of hook 5 is:

[0140] i. The mobile mechanism drives the power supply device to move to contact with the power receiving device on the vehicle body 2 to distribute power to the rotating mechanism 4;

[0141] ii. The rotating mechanism 4 rotates, and the hook 5 rotates from a horizontal state to a vertical state and extends out of the inner side of the cover plate 3 for mounting, or rotates from a vertical state to a horizontal state and retracts into the inner side of the cover plate 3 to prepare for the next mounting;

[0142] iii. The moving mechanism drives the power supply device to move to be separated from the power supply device on the vehicle body 2, and the rotating mechanism 4 is powered off, thereby completing an extension or retraction action of the hook 5 from the inner side of the cover plate 3.

[0143] Embodiment 5

[0144] The logistics system includes the rail trolleys in embodiments one to three.

[0145] Furthermore, the logistics system also includes a site, which is located in a logistics transfer area.

[0146] Specifically, the site is an area in the prior art where the mount is switched in logistics position, in which the mount can be transferred from the original plane to another plane.

[0147] Furthermore, the opening and closing sections in the rail trolley are arranged at the station.

[0148] The rail trolley, use method and logistics system provided by the present invention have novel structure, small space occupation, can meet the mounting requirements of various specifications, the rail 1 can be covered, the overall quality is light and thin, and the appearance is straight and neat. Taking the third embodiment as an example, the working process of the rail trolley is as follows:

[0149] 1. The travel drive 7 drives the vehicle body 2 to move along the track 1 to the opening and closing section;

[0150] 2. Drive the movable sliding door to move and open through the pushing mechanism;

[0151] 3. In the opening and closing section, the moving mechanism drives the power supply device to contact the power supply device on the vehicle body 2 to supply power to the motor in the rotating mechanism 4;

[0152] 4. Start the motor to rotate forward, and the motor drives the shaft on the connecting plate 51 to rotate through the coupling until the hook 5 rotates to a vertical state and extends out of the middle seam 32 of the cover plate 3, and then the motor is turned off;

[0153] 5. The mobile mechanism then drives the power supply device to separate from the power supply device on the vehicle body 2;

[0154] 6. Make the pushing mechanism drive the movable sliding door to move and close;

[0155] 7. Then, directly mount items or hang turnover boxes between the two groups of hooks 5, that is, adjust the distance between the two groups of hooks 5 according to the mounting specifications, and make them clamp the mounted items or turnover boxes. Specifically, start the electric push rod 81 to retract, and the electric push rod 81 stretches the tension spring 92, and the tension spring 92 drives the moving component 822 to pull the rotating mechanism 4 to slide along the guide rail 821. At this time, the other group of moving components 822 moves synchronously towards each other with the assistance of the pulling component 823, so that the two groups of hooks 5 are close to each other until they are against the items to be mounted or the turnover boxes. The hooks 5 stop moving, and the electric push rod 81 continues to retract, further stretching the tension spring 92, applying a greater clamping force to the hooks 5, until the tension value of the tension spring 92 reaches the set value of the position sensor, and the electric push rod 81 is controlled to stop working, so that the hooks 5 clamp the mounted items or turnover boxes, and then the travel drive 7 drives the vehicle body 2 to move along the track 1 to carry out logistics transportation;

[0156] Alternatively, the vehicle body 2 is first driven by the travel drive 7 to move along the track 1 to the mounting area 6 or the turnover box mounting area, and after the items are mounted or the turnover boxes are mounted between the two sets of hooks 5 (the specific operation method of mounting between the two sets of hooks 5 is as described above), the vehicle body 2 is then driven by the travel drive 7 to move along the track 1 to carry out logistics transfer;

[0157] 8. After the items or turnover boxes to be mounted are transferred to the corresponding position, the travel drive 7 is turned off and the items are unloaded on the two groups of hooks 5, that is, the electric push rod 81 is started to extend, and the electric push rod 81 pushes the tension spring 92, and the tension spring 92 drives the moving component 822 to pull the rotating mechanism 4 to slide along the guide rail 821. At this time, the other group of moving components 822 moves synchronously towards each other with the assistance of the pulling component 823, so that the two groups of hooks 5 are separated from each other until the items or turnover boxes to be mounted are released, thereby realizing a one-time transfer of the items or turnover boxes;

[0158] 9. Afterwards, if there is no need to transfer items or turnover boxes, repeat the above steps 1 to 3 first, and make the distance between the two groups of hooks 5 as large as possible, that is, the electric push rod 81 continues to push the tension spring 92, and the tension spring 92 drives the moving component 822 to pull the rotating mechanism 4 to continue to slide along the guide rail 821. At this time, the other group of moving components 822, with the assistance of the pulling component 823, moves synchronously towards each other, so that the two groups of hooks 5 continue to move away from each other, until the two groups of hooks 5 are in a position that can ensure that they are just horizontally flipped into the accommodating area 21, and then start the motor to reverse, and the motor drives the shaft on the connecting plate 51 to rotate through the coupling until the hook 5 rotates from the vertical state to the horizontal state and retracts to the inner side of the cover plate 3, and then repeat the above steps 5 and 6, thereby completing one working use of the hook 5. If it is necessary to continue to transfer the next group of items or turnover boxes, repeat the above steps 7 and 8 to complete the transfer operation of batch items or turnover boxes.

[0159] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of this patent.
