[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise stated, the directional words such as "upper" and "lower" used generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0036] The embodiments of the present application provide a turnover mechanism and a fire linkage turnover device, which are described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0037] First, the embodiment of the present application provides a flip mechanism, which is used in a fire linkage flip device, and the fire linkage flip device also includes a fire mechanism, and the flip mechanism and the fire mechanism are distributed along a first direction, that is, the fire mechanism is located above the flip mechanism. Figures 1 to 4 As shown, the flip mechanism 100 includes a bracket 110, and the bracket 110 has a support surface 111 for supporting and installing other structures. The bracket 110 is a frame structure for ensuring the overall structural stability of the flip mechanism 100.

[0038] The flip mechanism 100 includes a track assembly 120, which is located on the support surface 111. The track assembly 120 is used for the transportation mechanism to pass through, so as to realize the transportation of items in the warehouse. The track assembly 120 includes a first track 121 and a second track 122 distributed along the passing direction of the transportation mechanism. The first track 121 is connected to the bracket 110, and the second track 122 is rotatably connected to the bracket 110 around the rotation axis a. The rotation axis a extends along the second direction Y, and the second direction Y is at an angle to the first direction Z. That is, when the transportation mechanism passes on the track assembly 120, it passes along the first track 121 and the second track 122 in sequence, wherein the first track 121 is a fixed track and the second track 122 is a movable track, which is used to change the passage mode of the transportation mechanism on the track assembly 120.

[0039] It should be noted that when the first track 121 and the second track 122 are straight tracks, the extension direction of the first track 121 and the second track 122 can be defined as a third direction X, and the extension direction of the rotation axis a of the second track 122 (i.e., the second direction Y) is perpendicular to the third direction X, that is, the second track 122 rotates on a plane perpendicular to the first track 121, and the first direction Z is a vertical direction, and the first direction Z, the second direction Y and the third direction X are perpendicular to each other.

[0040] Among them, the first track 121 and the second track 122 can also be set as curved tracks, that is, the first track 121 and the second track 122 extend along a curve. The specific setting method can be designed and adjusted according to actual transportation needs, and there is no special limitation here.

[0041] The flipping mechanism 100 includes a first driving component 130, which is connected to the second track 122. The first driving component 130 is used to drive the second track 122 to rotate around the rotation axis a between a passing position and an avoidance position; when the second track 122 is located at the passing position, the extension direction of the second track 122 is consistent with the passing direction of the transportation mechanism, so that the transportation mechanism can pass along the first track 121 and the second track 122; when the second track 122 is located at the avoidance position, the second track 122 is used to avoid the fire-fighting mechanism 200, so that the fire-fighting mechanism 200 can be raised and lowered in the first direction Z.

[0042] Since the warehouse has multiple partitions, in order to ensure the integrity of the warehouse, two adjacent partitions need to be connected by rails. However, fire safety requires that fire prevention measures be taken between two adjacent partitions. Fire prevention measures require the use of fireproof rolling shutters as fire-fighting mechanisms 200 for fire isolation. Therefore, while using the rail assembly 120 in the flip mechanism 100 to achieve the connection between two adjacent partitions, it cannot affect the isolation work of the fire-fighting mechanism 200. In the embodiment of the present application, the second track 122 is set as a movable track, and the first driving component 130 is used to drive the second track 122 to rotate, and the fire-fighting mechanism 200 is set corresponding to the second track 122. When there is no fire, the second track 122 is in the passage position. At this time, the second track 122 and the first track 121 are located in the same plane, so that the transportation mechanism can pass smoothly between the two adjacent partitions along the first track 121 and the second track 122; when a fire occurs, the second track 122 rotates to the avoidance position. At this time, the plane where the second track 122 is located is at an angle (such as vertical) to the plane where the first track 121 is located, so as to leave space for the fire-fighting mechanism 200 to rise and fall, so that the fire-fighting mechanism 200 can rise and fall in the first direction Z, thereby separating the two adjacent partitions and playing a role in fire protection.

[0043] Optional, such as Figure 5As shown, a buffer 140 is convexly provided on the support surface 111 of the bracket 110. When the second track 122 is located at the passage position, the second track 122 abuts against the buffer 140. When the second track 122 is located at the avoidance position, the second track 122 is separated from the buffer 140. Since the second track 122 is a movable track, when the first driving assembly 130 is used to drive the second track 122 to rotate between the passage position and the avoidance position, especially when rotating from the avoidance position to the passage position, the second track 122 may collide with the support surface 111 of the bracket 110. By arranging the buffer 140 on the support surface 111, it can play a certain buffering role when the second track 122 collides with the support surface 111, thereby reducing the noise and impact force generated when the second track 122 rotates. Among them, the buffer 140 can be made of a material with a certain buffering capacity such as nylon.

[0044] In some embodiments, at least two buffer members 140 are protruding from the support surface 111 so that the second rail 122 can have at least two force points when colliding with the support surface 111, further improving the buffering effect and making the force on the second rail 122 more uniform when rotating from the avoidance position to the passing position.

[0045] Among them, at least two buffer members 140 are distributed along the second direction Y, that is, at least two buffer members 140 are distributed along the width direction of the second rail 122, so that the second rail 122 can be more evenly stressed in the width direction when it is in the passing position, thereby avoiding tilting of the transport mechanism in the width direction during the passage, and improving the stability of the transport mechanism when passing on the second rail 122.

[0046] Alternatively, at least two buffer members 140 are distributed along the travel direction of the transport mechanism, that is, at least two buffer members 140 are distributed along the length direction of the second rail 122, so that the force on the second rail 122 in the length direction is more uniform when the second rail 122 is in the passing position, avoiding the second rail 122 from being dented or deformed in the length direction after the transport mechanism has passed for a long time, thereby improving the stability of the transport mechanism when passing on the second rail 122.

[0047] Alternatively, at least two buffer members 140 are distributed along the second direction Y, and at least two buffer members 140 are distributed along the passing direction of the transport mechanism, that is, multiple buffer members 140 are distributed in an array on the support surface 111, so as to further improve the force uniformity when the second rail 122 is in the passing position, thereby further improving the stability of the transport mechanism when passing on the second rail 122.

[0048] It should be noted that the specific arrangement of the buffer member 140 on the support surface 111 can be selected and adjusted according to actual use requirements, and it is only necessary to ensure the stability of the transportation mechanism when passing on the second track 122, and no special restrictions are made here.

[0049] Optional, such as Figure 5 As shown, a stopper 150 is also protruded on the support surface 111 of the bracket 110, and the second track 122 has a stopper. When the second track 122 is in the passage position, the stopper 150 abuts against the side wall of the stopper to limit the movement of the second track 122 relative to the bracket 110 in the second direction Y. Since the second track 122 is a movable track, when the second track 122 is in the passage position and the transport mechanism passes on the second track 122, the second track 122 may shake in the second direction Y. By arranging the stopper 150 on the support surface 111, the movement of the second track 122 relative to the bracket 110 in the second direction Y can be limited, thereby improving the stability of the transport mechanism when passing on the second track 122. Among them, the stopper 150 can be made of nylon material, which can not only play a limiting role but also play a certain buffering role on the shaking of the second track 122.

[0050] In some embodiments, at least two limit members 150 are protruding from the support surface 111, and correspondingly, the second rail 122 has at least two limit portions. When the second rail 122 is in the passing position, the limit members 150 abut against the limit portions one by one to further limit the movement of the second rail 122 relative to the bracket 110 in the second direction Y, thereby improving the stability of the transportation mechanism when passing on the second rail 122.

[0051] Among them, at least two limit members 150 are distributed along the second direction Y, that is, at least two limit members 150 are distributed along the width direction of the second rail 122, so that the second rail 122 can be more evenly stressed in the width direction when it is in the passing position, thereby avoiding tilting of the transport mechanism in the width direction during the passage, and improving the stability of the transport mechanism when passing on the second rail 122.

[0052] Alternatively, at least two limit members 150 are distributed along the travel direction of the transport mechanism, that is, at least two limit members 150 are distributed along the length direction of the second rail 122, so that the force on the second rail 122 in the length direction is more uniform when the second rail 122 is in the travel position, avoiding depression or deformation of the second rail 122 in the length direction after the transport mechanism passes for a long time, thereby improving the stability of the transport mechanism when passing on the second rail 122.

[0053] Alternatively, at least two limit members 150 are distributed along the second direction Y, and at least two limit members 150 are distributed along the passing direction of the transport mechanism, that is, multiple limit members 150 are distributed in an array on the support surface 111, so as to further improve the force uniformity when the second rail 122 is in the passing position, thereby further improving the stability of the transport mechanism when passing on the second rail 122.

[0054] It should be noted that the specific arrangement of the upper limit member 150 on the support surface 111 can be selected and adjusted according to actual usage requirements, and it is only necessary to ensure the stability of the transportation mechanism when passing on the second track 122, and no special restrictions are made here.

[0055] Optional, such as Figure 3 and Figure 4 As shown, the flip mechanism 100 includes two track assemblies 120 and two first drive assemblies 130. The two track assemblies 120 are distributed along the first direction Z. The two first drive assemblies 130 are respectively connected to the second tracks 122 in the two track assemblies 120 to synchronously drive the two second tracks 122 to rotate around the rotation axis a between the passage position and the avoidance position. That is, the bracket 110 is a double-layer structure. The bracket 110 has two support surfaces 111 in the first direction Z. Each support surface 111 is correspondingly provided with a track assembly 120. Each track assembly 120 is correspondingly connected to a first drive assembly 130, and the two first drive assemblies 130 synchronously drive the corresponding track assembly 120, so that the track assembly 120 in the flip mechanism 100 is used to realize the connection between two adjacent partitions without affecting the isolation work of the fire fighting mechanism 200, and the space utilization rate of the flip mechanism 100 can be improved, thereby meeting the transportation needs of the warehouse.

[0056] Secondly, an embodiment of the present application provides a fire linkage flipping device, which includes a flipping mechanism. The specific structure of the flipping mechanism refers to the above embodiment. Since the fire linkage flipping device adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0057] like Figure 1 and Figure 2 As shown, the fire linkage flip device 10 includes a flip mechanism 100 and a fire mechanism 200. The fire mechanism 200 and the flip mechanism 100 are distributed along the first direction Z, that is, the fire mechanism 200 is located above the flip mechanism 100. The fire mechanism 200 includes a fireproof member 210 and a second drive assembly. The second drive assembly is connected to the fireproof member 210, and the second drive assembly is used to drive the fireproof member 210 to rise and fall in the first direction Z. That is, the second drive assembly cooperates with the first drive assembly 130 in the flip mechanism 100. When the first drive assembly 130 drives the second track 122 in the flip mechanism 100 to rotate from the passing position to the avoidance position, a space for the fire mechanism 200 to rise and fall can be reserved below the fire mechanism 200. The second drive assembly drives the fireproof member 210 to rise and fall in the first direction Z to separate two adjacent partitions, thereby playing a role in fire protection.

[0058] Optionally, the flip mechanism 100 includes a first control module, which is electrically connected to the first drive assembly 130, and the fire fighting mechanism 200 includes a second control module, which is electrically connected to the second drive assembly, and the second control module is electrically connected to the first control module, that is, the flip mechanism 100 and the fire fighting mechanism 200 are electrically connected through the first control module and the second control module to facilitate the transmission of signals between the two. The second control module is used to receive the first fire fighting signal and output the first control signal according to the first fire fighting signal, and the first control module is used to receive the first control signal and control the first drive assembly 130 to drive the second track 122 in the flip mechanism 100 to rotate from the passage position to the avoidance position according to the first control signal.

[0059] Among them, the first fire signal is a fire alarm signal. When a fire occurs, the second control module converts the received first fire signal into a first control signal, and transmits the first control signal to the first drive component 130 through the first control module. The first drive component 130 drives the second track 122 in the flipping mechanism 100 to rotate from the pass position to the avoidance position according to the first control signal to leave space for the fire fighting mechanism 200 to be lifted and lowered.

[0060] It should be noted that before transmitting the first control signal to the first drive component 130, the first control module will first monitor whether there is a transportation mechanism on the track component 120 passing through the second track 122. If not, the first control signal will be transmitted to the first drive component 130 to avoid interference with the transportation mechanism during the rotation of the second track 122, thereby causing a safety accident.

[0061] The flip mechanism 100 includes a first photoelectric sensor, which is electrically connected to the first control module. The first photoelectric sensor is used to monitor the position of the second track 122 and output a second control signal. The second control module is used to receive the second control signal and control the second drive assembly to drive the fireproof member 210 to descend according to the second control signal. That is, when the first drive assembly 130 drives the second track 122 to rotate from the passage position to the avoidance position, the first photoelectric sensor is used to monitor whether the second track 122 rotates to the specified position. When the second track 122 rotates to the designated position, the first photoelectric sensor transmits the second control signal to the second control module, and the second control module controls the second drive assembly to drive the fireproof member 210 to descend according to the second control signal to achieve fire isolation.

[0062] Correspondingly, the fire-fighting mechanism 200 includes a second photoelectric sensor, which is electrically connected to the second control module; the second control module is used to receive a second fire-fighting signal, and control the second drive component to drive the fire-fighting element 210 to rise according to the second fire-fighting signal. The second photoelectric sensor is used to monitor the position of the fire-fighting element 210 and output a third control signal. The first control module is used to receive the third control signal, and control the first drive component 130 to drive the second track 122 to rotate from the avoidance position to the passing position according to the third control signal.

[0063] Among them, the second fire signal is a fire alarm relief signal. When the fire alarm is relieved, the second control module controls the second drive component to drive the fire prevention component 210 to rise according to the received second fire signal, and the second photoelectric sensor is used to monitor whether the fire prevention component 210 rises to the specified position. When the fire prevention component 210 rises to the designated position, the second photoelectric sensor transmits a third control signal to the first control module, and the first control module controls the first drive component 130 to drive the second track 122 to rotate from the avoidance position to the passing position according to the third control signal to facilitate the normal passage of the conveying mechanism.

[0064] It should be noted that the first drive component 130 and the second drive component in the embodiment of the present application are variable frequency band wrapped motors, which control the speed of the motor when it is opened and closed by frequency conversion, so as to reduce the noise and impact force generated when the second track 122 and the fire-setting component are in action; at the same time, the motor locks the second track 122 by wrapping to prevent the transportation mechanism from tilting when passing on the second track 122, thereby ensuring the stability of the fire linkage flipping device 10 during operation.

[0065] The above is a detailed introduction to a flipping mechanism and a fire linkage flipping device provided in the embodiments of the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for technical personnel in this field, according to the ideas of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
