Description

Technical Field

[0001] The invention relates to the technical field of steel cable rail transportation, in particular to a rail changing and merging saddle. Background Art

[0002] With the rapid development of the logistics industry, new transportation methods and equipment have emerged one after another. The transportation logistics method of low-altitude cable rails is more time-saving and labor-saving than traditional logistics, and is more competitive in the market. For example, the logistics shuttle robot with intelligent distribution function, as the main carrier of rail-type or cableway logistics, only needs to set up cable rails between the logistics center and each distribution station, and then drive the logistics shuttle robot to run on the cable rails to achieve the purpose of transporting goods.

[0003] In reality, logistics distribution sites often need to be sited based on specific influencing factors such as regional administrative factors, geographical factors, and population density, which makes these logistics distribution sites present the characteristics of multi-point distribution in space. Considering the construction cost, when building distribution lines, steel cable rails are generally allowed to pass through distribution sites as much as possible to form a distribution main line or branch line.

[0004] However, the current cable rail logistics distribution system is a single-line logistics distribution system. No matter the main line or the branch line, it can only deliver goods to the distribution stations passed by the cable rail line. For the distribution stations not passed by the cable rail line, a new logistics distribution branch line leading to the logistics center can only be rebuilt to achieve the purpose of unmanned intelligent distribution of goods. However, the construction of a new logistics distribution branch line will obviously bring huge cost consumption, which is not conducive to production and construction. Summary of the invention

[0005] In order to overcome at least one of the defects of the above-mentioned prior art, the present invention provides a track changing and merging saddle, which first connects the switching rail to the steel cable rail of the distribution branch line, and then builds an operating track for the logistics shuttle robot between the switching rail and other main lines or branch lines, so as to achieve the purpose of merging the branch lines and connecting them to the logistics terminal. There is no need to rebuild a new logistics branch line distribution system, and a networked logistics distribution system in which one main line connects multiple branches can be realized, saving construction costs.

[0032] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0033] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0035] See also Figures 1 to 3 The present invention discloses a track-changing and merging saddle, which is used to build a movable track for a logistics shuttle robot to run between a first steel cable rail 1 and a second steel cable rail 2 leading to a distribution main line or a distribution branch line separated from the first steel cable rail 1, wherein the saddle includes at least one switching beam 3 erected on one side of the first steel cable rail 1, and the switching beam 3 is provided with at least one switching rail 4 connected to the running track of the second steel cable rail 2; the first end portion 401 of the switching rail 4 is configured to be able to move to the running track of the logistics shuttle robot on the first steel cable rail 1, so that the logistics shuttle robot can switch the running track between the first steel cable rail 1 and the second steel cable rail 2.

[0036] The rail-changing and merging saddle disclosed in this embodiment sets up a switching rail 4 connected to the running rail of the second steel cable rail 2 on the side of the first steel cable rail 1 through a switching beam 3, and controls the first end 401 of the switching rail 4 so that it can move to the running rail of the first steel cable rail 1, thereby providing a logistics shuttle robot with a switching running rail between the first steel cable rail 1 and the second steel cable rail 2, so as to achieve the purpose of connecting the first steel cable rail 1 and the second steel cable rail 2, and the second steel cable rail 2 leads to a distribution branch line separated from the first steel cable rail 1, so as to achieve the purpose of building a running track for the logistics shuttle robot to transport goods between the first steel cable rail 1 and the distribution line that is not crossed by the first steel cable rail 1. And by controlling the first end 401 of the switching rail 4, it can be separated from the first steel cable rail 1 in time, so as to achieve the purpose of ensuring the normal operation of the logistics shuttle robot on the first steel cable rail 1.

[0037] In practical applications, the distribution line of the distribution site with the most routes can be selected as the main line of logistics transportation, that is, the running track of the first steel cable rail 1 described in the present embodiment, and then between the remaining distribution sites that are not crossed by the first steel cable rail 1, a suitable branch line, that is, the second steel cable rail 2 described in the present embodiment, is built, and the second steel cable rail 2 is connected to the main line, that is, the first steel cable rail 1, through the track-changing saddle, that is, track-joining, so that the purpose of spatial multi-line logistics distribution can be achieved. The purpose of connecting the distribution lines that are not passed through can be achieved without building a new logistics distribution system. By using the existing main line with the closest distance, combined with the branch line, the purpose of connecting each distribution line with the logistics terminal can be achieved. Obviously, by using the method of track-joining transportation, a large amount of construction costs can be saved, and the same shuttle can also achieve the purpose of transporting goods to more distribution points at the same time, that is, track-changing, so as to reduce the number of round trips of the logistics shuttle robot and improve the distribution efficiency.

[0038] In addition, the track-changing saddle can be used not only for switching connections between the distribution main line and the distribution branch line, but also for switching connections between the distribution branch line and the distribution branch line of the next level. At the same time, the steel cable rails of the same level can also be connected to multiple distribution lines at the same time, so as to achieve optimal utilization of the steel cable rails and improve transportation efficiency.

[0039] In summary, by replacing the track-joining saddle, the purpose of spatial multi-line interconnected logistics distribution can be achieved without rebuilding a new distribution branch line, which greatly saves construction costs. The spatial multi-point and multi-line logistics transportation system is also conducive to improving the logistics distribution efficiency.

[0040] Preferably, see Figure 2, and also includes a switching guide 5 for fixing the end of the second steel cable rail 2. The second steel cable rail 2 is fixedly installed on the switching beam 3 through the switching guide 5. Specifically, the end of the second steel cable rail 2 is wound on the switching guide 5, and the end is fixed to the switching beam 3 through a one-way anchor or a clamp or other fixing member to fix the second steel cable rail 2. The switching guide 5 can be a roller structure, and of course it can also be other structures;

[0041] At the same time, the second end 402 of the switching rail 4 is arranged on the switching beam 3 and is located in the axial extension direction of the running track of the second steel cable rail 2. The distance between the second end 402 of the switching rail 4 and the end of the running track of the second steel cable rail 2 is set to allow the logistics shuttle robot to pass through. By setting the second end 402 of the switching rail 4 in the axial extension direction of the running track of the second steel cable rail 2, the running track of the switching rail 4 and the running track of the second steel cable rail 2 can be smoothly connected.

[0042] Preferably, see Figure 2 and Figure 5 , and further includes a driver 6 for driving the first end 401 of the switching rail 4 to move, the driver 6 being arranged on the switching beam 3 to drive the first end 401 of the switching rail 4 to move to the running track of the first steel cable rail 1, or to drive the first end 401 of the switching rail 4 to move in a direction away from the first steel cable rail 1; specifically, when the first end 401 of the switching rail 4 moves to the running track of the first steel cable rail 1, the first end 401 of the switching rail 4 is located directly above the first steel cable rail 1, and the axis of the first end 401 of the switching rail 4 is parallel to the axis of the first steel cable rail 1, so as to achieve the first end 401 of the switching rail 4 being parallel to the axis of the first steel cable rail 1. 01 overlaps with the running track of the first steel cable rail 1, so that the logistics shuttle robot can run from the first steel cable rail 1 to the switching rail 4, or the logistics shuttle robot can run smoothly from the switching rail 4 to the first steel cable rail 1; when the first end 401 of the switching rail 4 is away from the first steel cable rail 1, the maximum distance between the first end 401 of the first steel cable rail 1 and the first steel cable rail 1 is configured to at least allow the logistics shuttle robot to run on the first steel cable rail 1, that is, when they are separated, the distance between the first end 401 and the first steel cable rail 1 needs to be greater than the running space of the logistics shuttle robot, so as to avoid the problem that the switching rail 4 interferes with the operation of the shuttle on the first steel cable rail 1. By controlling the driver 6, the second end 402 of the switching rail 4 is driven to move. Specifically, in this embodiment, the switching rail 4 has a certain elasticity or flexibility, and the driver 6 drives the first end 401 of the switching rail 4 to swing in the horizontal direction. Of course, it can also be configured to swing the first end 401 in the vertical direction.

[0043] Specifically, in this embodiment, the switch rail 4 can be made of existing bendable metal materials, such as stainless steel.

[0044] Preferably, see Figure 2 and Figure 5 The bottom of the switching rail 4 has a bendable support member 7 in a plate-like structure, and the bendable support member 7 extends along the axis direction of the switching rail 4. The bendable support member 7 in a plate-like structure can improve the anti-deformation ability of the switching rail 4 in the vertical direction and improve the structural stability, so that the logistics shuttle robot can pass smoothly.

[0045] Preferably, see Figure 1 , Figure 4 and Figure 6 , and also includes a column 8 for erecting the first steel cable rail 1, at least one main beam 9 is installed on the column 8, and at least two corresponding support wheels 10 are arranged on the main beam 9, and at least part of the side wall of the support wheel 10 in the circumferential direction is recessed toward the center of the support wheel 10 to form a support groove 1001 that matches the shape of the first steel cable rail 1, and the support groove 1001 is used to connect the first steel cable rail 1 to support the steel cable rail. By designing two corresponding support wheels 10, the first steel cable rail 1 is hung in the support grooves 1001 of the two support wheels 10, which can play the role of fixing and limiting the first steel cable rail 1 and supporting it, so as to facilitate the stable docking of the switching rail 4. Specifically, in addition to being used for hanging the first steel cable rail 1, the support wheel 10 can also be used as a truncation connection point of the first steel cable rail 1 in practice, that is, the first steel cable rail 1 is cut off from the steel cable rail section between the two support wheels 10, and then the ends of the two cut steel cable rail sections are respectively connected to the support wheels 10, see Figure 6 Then, a support hard rail 18 is designed between any two adjacent support wheels 10 located on the same main beam 9, and the support hard rail 18 is set on the running track of the first steel cable rail 1 of the logistics shuttle robot. With this design, the purpose of replacing the cut-off part of the first steel cable rail 1 with the support hard rail 18 with a hard texture can be achieved, that is, the support hard rail 18 is used to constitute at least part of the first steel cable rail 1; when the support hard rail 18 is set on the running track of the first end portion 401 of the switching rail 4, when the track needs to be merged, the first end portion 401 of the switching rail 4 will run to the hard support hard rail 18 with a hard texture, so as to improve the running stability of the shuttle when switching the running track.

[0046] See also Figure 6 and Figure 7 , and also includes a limiting structure 11 for locking the position of the first end 401 when it is on the running track of the first steel cable rail 1. The limiting structure 11 is arranged on the main beam 9 and is located on one side of the first steel cable rail 1.

[0047] Preferably, see Figure 7 The limiting structure 11 includes a slide bar 1101, a pressure plate 1102 and an elastic member 1103. The slide bar 1101 is slidably arranged on the main beam 9, the pressure plate 1102 is arranged on the top of the slide bar 1101, a locking head 1104 is arranged at the bottom of the pressure plate 1102, and the elastic member 1103 is arranged between the pressure plate 1102 and the main beam 9. Specifically, the elastic member 1103 is preferably a spring, which is sleeved on the slide bar 1101; a locking plate 12 is provided at the bottom of the switching rail 4, and a locking hole 13 is provided on the locking plate 12. When the first end 401 of the switching rail 4 is located directly above the first steel cable rail 1, the locking head 1104 is located directly above the locking hole 13 to achieve the purpose of alignment; the pressure plate 1102 is arranged within the operating range of the logistics shuttle robot 1, and when the logistics shuttle robot runs to the first end 401 of the switching rail 4, the locking head 1104 on the pressure plate 1102 is located in the locking hole 13.

[0048] Specifically, since the pressure plate 1102 is set within the operating range of the first steel cable rail 1 of the logistics shuttle robot, when it is necessary to switch the operating track, the first end 401 of the switching rail 4 will run to the supporting hard rail 18, and the locking plate 12 at the bottom of the switching rail 4 will also follow and run to the main beam 9 under the first steel cable rail 1, and the locking hole 13 on the locking plate 12 will correspond to the locking head 1104 (that is, the locking hole 13 is within the movement range of the locking head 1104). Before the logistics shuttle robot runs to the position of the first end 401, it will contact and squeeze the pressure plate 1102 to drive the locking head 1104 on the pressure plate 1102 to move downward so as to be inserted into the locking hole 13, thereby achieving the purpose of the logistics shuttle robot locking the switching rail 4 directly above the first steel cable rail 1 before entering the switching rail 4, so as to avoid the problem of derailment of the switching rail 4 when changing tracks, thereby improving the safety of equipment operation and structural stability.

[0049] Preferably, see Figure 3 and Figure 7, further comprising a first position sensor 14 arranged on one side of the first steel cable rail 1, the first position sensor 14 being electrically connected to the driver 6; a detection plate 15 being arranged on the switching rail 4, the detection head of the first position sensor 14 being located within the movement range of the detection plate 15; when the first end 401 of the switching rail 4 moves onto the running track of the first steel cable rail 1, the detection plate 15 contacts the detection head of the first position sensor 14 to sense the movement position of the first end 401 of the switching rail 4, and when the position information is a preset value, the information can be fed back to the driver 6 to instruct the driver 6 to stop, so that the switching rail 4 can be normally stopped directly above the first steel cable rail 1. The first position sensor 14 is used to achieve the purpose of alignment detection of the switching rail 4, so as to avoid the problem of the switching rail 4 stopping before it runs onto the running track of the first steel cable rail 1, and also to avoid the problem of the switching rail 4 over-moving and crossing the first steel cable rail 1. By designing a first position sensor 14 on the main beam 9 for detecting whether the first end 401 of the switching rail 4 is accurately in place, the position accuracy of the switching rail 4 when running to the running track of the first cable rail 1 can be improved.

[0050] Preferably, see Figure 7 A supporting plate 151 is provided at the bottom of the detection plate 15, and the supporting plate 151 is correspondingly arranged between the main beam 9 and the first steel cable rail 1. When the logistics shuttle robot runs on the switching rail 4, the switching rail 4 will sink due to the gravity of the logistics shuttle robot, and the supporting plate 151 above the main beam 9 will be pressed down to abut against the main beam 9, so as to support the switching rail 4 and improve the structural stability.

[0051] Preferably, see Figure 3 and Figure 7 The first end 401 of the switching rail 4 has an inclined surface 16, which is arranged upwardly and inclined. The inclined surface 16 is arranged so that the end of the switching rail 4 can be smoothly connected with the running track of the first cable rail 1 to reduce the vibration when the shuttle switches the rail 4 and improve the stability.

[0052] Preferably, see Figure 4 and Figure 5, and also includes a second position sensor 17 for sensing the position information of the logistics shuttle robot. The second position sensor 17 is arranged on the side of the second end 402 of the switching rail 4 and is located within the operating range of the logistics shuttle robot of the first steel cable rail 1. The second position sensor 17 is electrically connected to the driver 6. When the shuttle runs from the first end 401 to the second end 402 of the switching rail 4, it will touch the second position sensor 17. When the second position sensor 17 senses that the logistics shuttle robot has left the switching rail 4, the driver 6 can be started to drive the switching rail 4 to separate from the first steel cable rail 1, so as to provide normal operation of the logistics shuttle robot on the first steel cable rail 1. Of course, the first position sensor 14 can also be combined with the second position sensor 17 to feed back detection information to each other, so as to achieve the purpose of comprehensively detecting the motion information of the shuttle in the operating track of the switching rail 4.

[0053] Preferably, see Figure 1 A cross beam 19 is provided on the column 8, and a switching beam 20 is installed at the end of the cross beam 19 away from the main beam 9, and the switching beam 3 is installed on the switching beam 20; the space between the switching beam 20 and the main beam 9 forms a channel for the shuttle to run through on the first steel cable rail 1, and the channel realizes the normal passage of the logistics shuttle robot. By designing the cross beam 19 and the switching beam 20, the purpose of installing the switching beam 3 and the main beam 9 on the same column 8 is achieved, saving costs.

[0054] Preferably, see Figure 5 The driver 6 is a linear push rod motor, and the push rod of the linear push rod motor is connected to the flexible support 7. In this embodiment, the push rod of the linear push rod motor is driven to move so that it can push the side of the switching rail 4, so that the switching rail 4 is bent. The purpose of driving the second end 402 of the switching rail 4 to operate is achieved by controlling the bending degree of the switching rail 4. Specifically, the main body of the linear push rod motor is hinged to the switching beam 3, and the push rod of the linear push rod motor is hinged to the flexible support 7.

[0055] In addition, the driver 6 may also be other structures, such as a cylinder.

[0056] In summary, the rail-changing and merging saddle disclosed in this embodiment can bring the following beneficial effects:

[0057] By means of the track-changing saddle, the switching rail is connected to the steel cable rail of the branch line, and then a running track for the logistics shuttle robot is built between the switching rail and other main lines or branch lines, so that the branch line can be connected to the main line, and a networked logistics distribution system in which one main line connects multiple branch lines can be realized, saving construction costs. The networked logistics distribution system in which one main line connects multiple branch lines is also conducive to improving the logistics distribution efficiency; the limiting structure can prevent the shuttle from derailing when switching the running track, and improve the safety and structural stability of the equipment operation; by designing a first position sensor on the main beam for detecting whether the first end of the switching rail is accurately in place, the position accuracy of the switching rail when it runs to the running track of the first steel cable rail can be improved; a supporting hard rail is designed on the main beam, and the supporting hard rail is set on the running track of the logistics shuttle robot on the first steel cable rail, so as to replace the truncated part of the first steel cable rail with a hard supporting hard rail; when the supporting hard rail is set on the running track of the first end of the switching rail, the running stability of the shuttle when switching the running track can be improved.
