Description

Technical Field

[0001] This application relates to the field of rail transport equipment technology, and in particular to a joint device. Background Technology

[0002] In fields such as automation equipment, mechanical engineering, and rail transportation equipment, RGVs (Rail Guided Vehicles) are common devices, primarily used for transporting materials within factories. In practical applications, RGVs need to move between different workshops or buildings, requiring the use of rail joints to connect rails of varying lengths. However, due to the influence of ambient temperature, expansion joints between buildings can widen or narrow, causing the rails to bend or break, thus affecting the normal operation of the RGV.

[0003] To address these issues, related technologies typically employ rigid connections at the track joints, such as welding or bolting. While this method can prevent track bending or breakage to some extent, it can damage the track joints when expansion joints between buildings change significantly, thus affecting the normal operation of the RGV. Furthermore, frequent changes in building expansion joints shorten the lifespan of the track joints; additionally, the track joint design in these technologies may not guarantee track smoothness, impacting the RGV's operational stability and efficiency. Utility Model Content

[0059] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0060] This application provides a connector device, including a first connector and a second connector. The first connector includes a first support, a first track body, a first insertion structure, and a second insertion structure. The first insertion structure is disposed at a first end of the first track body. The first track body is disposed on the first support. The second insertion structure is disposed at the first end of the first track body and located to one side of the first insertion structure, with a length greater than the length of the first insertion structure. The second connector includes a second support, a second track body, a third insertion structure, and a fourth insertion structure. The second track body is disposed on the second support. The third insertion structure is disposed at a first end of the second track body. The fourth insertion structure is disposed at the first end of the second track body and located to one side of the third insertion structure, with a length greater than the length of the third insertion structure. The first insertion structure and the third insertion structure are slidably connected, and the second insertion structure and the fourth insertion structure are slidably connected. This configuration ensures that when the first and third insertion structures are stretched to their furthest positions, the second and fourth insertion structures remain connected, thereby allowing for a larger expansion and contraction compensation range and further ensuring the flatness and durability of the track connector.

[0061] The specific embodiments described below are intended to help those skilled in the art understand this embodiment, but this embodiment is not limited to the specific embodiments described below.

[0062] like Figures 1-2 As shown, an exemplary embodiment of this application provides a connector device, including a first connector 1 and a second connector 2; the first connector 1 includes a first support portion 11, a first track body 12, a first insertion structure 13 and a second insertion structure 14, the first track body 12 is disposed on the first support portion 11, the second insertion structure 14 is disposed at the first end of the first track body 12 and located on one side of the first insertion structure 13, and the length of the second insertion structure 14 is greater than the length of the first insertion structure 13.

[0063] like Figures 3-4 As shown, the second connector 2 includes a second support portion 21, a second track body 22, a third insertion structure 23, and a fourth insertion structure 24. The second track body 22 is disposed on the second support portion 21; the third insertion structure 23 is disposed at the first end of the second track body 22; the fourth insertion structure is disposed at the first end of the second track body 22 and located on one side of the third insertion structure 23, and the length of the fourth insertion structure 24 is greater than the length of the third insertion structure 23. The first insertion structure 13 is slidably connected to the third insertion structure 23, and the second insertion structure 14 is slidably connected to the fourth insertion structure 24.

[0064] In this embodiment, through the cooperation of the first plug-in structure 13 and the third plug-in structure 23, and the cooperation of the second plug-in structure 14 and the fourth plug-in structure 24, the first connector 1 and the second connector 2 can be interlocked and slide relative to each other, ensuring that the horizontal and vertical alignment of both ends of the track connector is consistent and straight, while also adapting to the frequent thermal expansion and contraction of the building. Furthermore, the connector device of this application has a simple and reliable structure, ensuring the reliable and smooth operation of the RGV. It can be applied to the connection of RGV tracks between different buildings requiring expansion and contraction compensation, the connection of large heavy-duty RGV track joints requiring reliable reinforcement, and the connection of track assembly extension within the same building. In addition, since the length of the second plug-in structure 14 is greater than the length of the first plug-in structure 13, and the length of the fourth plug-in structure 24 is greater than the length of the third plug-in structure 23, it can be ensured that when the first plug-in structure 13 and the third plug-in structure 23 are stretched to their furthest positions, the second plug-in structure 14 and the fourth plug-in structure 24 remain connected, thereby allowing for a larger expansion and contraction compensation range and further ensuring the flatness and durability of the track connector.

[0065] like Figure 2 and Figure 4 As shown, the first insertion structure 13 includes at least one first top surface tenon 131, at least one first top surface groove 132, at least one first side surface tenon 133, and at least one first side surface groove 134, with the at least one first top surface tenon 131 and at least one first top surface groove 132 alternately arranged on the horizontal plane; the third insertion structure 23 includes a second top surface tenon 231 corresponding to the first top surface groove 132, a second top surface groove 232 corresponding to the first top surface tenon 131, a second side surface tenon 233 corresponding to the first side surface groove 134, and a second side surface groove 234 corresponding to the first side surface tenon 133, with the second top surface tenon 231 and the second top surface groove 232 alternately arranged on the horizontal plane; as Figures 5-7 As shown, the first top surface protrusion 131 is slidably connected to the corresponding second top surface groove 232, the second top surface protrusion 231 is slidably connected to the corresponding first top surface groove 132, the first side surface protrusion 133 is slidably connected to the corresponding second side surface groove 234, and the second side surface protrusion 233 is slidably connected to the corresponding first side surface groove 134.

[0066] like Figure 8As shown, an expansion joint 50 is provided between the first building 10 and the second building 30. In this embodiment, the first connector 1 can be used as a fixed end, fixed to the ground of the first building 10, and the second end of the first connector 1 is connected to the first track 20; the second connector 2 can be used as a movable end, set at the second building 30, and the second end of the second connector 2 is connected to the second track 40. During assembly, after aligning the top and side surfaces of the first connector 1 and the second connector 2, the first end of the first connector 1 is inserted into the first end of the second connector 2. That is, the first top surface tenon 131 is inserted into the corresponding second top surface groove 232, and the second top surface tenon 231 is inserted into the corresponding first top surface groove 132. The first side surface tenon 133 is inserted into the corresponding second side surface groove 234, and the second side surface tenon 233 is inserted into the corresponding first side surface groove 134. In this way, each tenon and each groove can be interlocked to form a mortise and tenon structure. The planar and height positions of the first track 20 connected to the first connector 1 and the second track 40 connected to the second connector 2 are mutually constrained. That is, the movable end of the second track 40 is fixed in horizontal and height position through the fixed end connected to the ground, so that the track remains straight at the joint. And because each tenon and each groove can slide, the joint device can freely expand and contract with the expansion joint 50. The joint device can realize the connection between the first track 20 and the second track 40, ensuring the smooth operation of the RGV.

[0067] The number of the first top surface tenon 131, the first top surface groove 132, the first side surface tenon 133, the first side surface groove 134, the second top surface tenon 231, the second top surface groove 232, the second side surface tenon 233, and the second side surface groove 234 is not limited. It is sufficient that the first top surface tenon 131 corresponds to the second top surface groove 232, the second top surface tenon 231 corresponds to the first top surface groove 132, the first side surface tenon 133 corresponds to the second side surface groove 234, and the second side surface tenon 233 corresponds to the first side surface groove 134. For example... Figure 2 and Figure 4 In this design, the number of the first top surface tenon 131, the first top surface groove 132, the first side surface tenon 133, the first side surface groove 134, the second top surface tenon 231, the second top surface groove 232, the second side surface tenon 233, and the second side surface groove 234 are all set to two.

[0068] After the first joint 1 and the second joint 2 are assembled and fitted, the top and side surfaces of the joints can be aligned and mutually constrained to ensure the straightness of the joints. When the size of the expansion joint 50 changes due to thermal expansion and contraction of the first building 10 and the second building 30, the first joint 1 and the second joint 2 can still slide relative to each other to compensate for the expansion and contraction of the building where they are installed, and continue to maintain the straightness of the first track 20 and the second track 40.

[0069] It should be noted that when multiple tenons and grooves are provided, the multiple first-side tenons 133 on the first side of the first joint 1 are arranged alternately on the vertical plane, and the multiple first-side grooves 134 on the second side of the first joint 1 are arranged alternately on the vertical plane. The multiple second-side tenons 233 and multiple second-side grooves 234 on the second joint 2 are also arranged alternately on the same side.

[0070] When one side of the first connector 1 has a first side tenon 133 at the same height, the other side needs to be a first side groove 134. Furthermore, when one side of the first connector 1 (e.g., the first side of the first track body 12) is a first side tenon 133, after assembly, the second connector 2, located at the same height as the first connector 1 on the same side (e.g., the second side of the second track body 22), needs to be a second side groove 234. With this arrangement, after the first connector 1 and the second connector 2 are assembled, the same side of the first connector 1 and the second connector 2 will form a new groove due to pre-stretching a certain gap. However, if there is a groove at a certain height on one side, there will inevitably be no groove at the same height on the other side. This ensures that one side of the guide wheels on both sides of the RGV track must be a groove-free surface close to the side of the track connector, thus ensuring the continuous and stable guidance of the RGV when passing through the track connector device. (Note: The wheels of the RGV are generally wider, and when passing over the track joint, the groove on the top surface of the joint has almost no impact on its normal operation; however, the guide wheels are generally narrower, and when there are grooves on both sides of the track joint, the guidance will fail. However, if the grooves on both sides of the joint device do not appear at the same time, it will not affect the smooth guidance of the guide wheels on both sides.)

[0071] In one embodiment, the second plug-in structure 14 further includes a first pad rail 141 disposed on the first support portion 11 and located below the first track body 12. The first pad rail 141 and the first support portion 11 have a first horizontal groove 142. The length of the first horizontal groove 142 is greater than the length of the first top surface groove 132, the first top surface tenon 131, the first side surface groove 134, and the first side surface tenon 133. The fourth insertion structure 24 also includes a second pad rail 241 and a horizontal tenon 242. The second pad rail 241 is disposed on the second support part 21 and located below the second track body 22. The horizontal tenon 242 is disposed on the second pad rail 241. A second horizontal groove 243 is provided between the horizontal tenon 242 and the second track body 22. The lengths of the horizontal tenon 242 and the second horizontal groove 243 are both greater than the lengths of the second top surface groove 232, the second top surface tenon 231, the second side surface groove 234, and the second side surface tenon 233. The first pad rail 141 is slidably connected to the second horizontal groove 243, and the horizontal tenon 242 is slidably connected to the first horizontal groove 142.

[0072] In this embodiment, the lengths of the first horizontal groove 142, the second horizontal groove 243, and the horizontal tenon 242 are all greater than the lengths of the first top surface groove 132, the first top surface tenon 131, the first side surface groove 134, the first side surface tenon 133, the second top surface groove 232, the second top surface tenon 231, the second side surface groove 234, and the second side surface tenon 233. This ensures that when the top surfaces of the track joint are stretched to their furthest positions, the first pad rail 141 remains connected to the second horizontal groove 243, and the horizontal tenon 242 remains connected to the first horizontal groove 142, thus allowing for a larger range of expansion and contraction compensation for the joint. The above structural design further ensures the flatness and durability of the track joint. The lengths of the first horizontal groove 142, the second horizontal groove 243, and the horizontal tenon 242 can be set according to the expansion and contraction range of the building.

[0073] After the joint device is installed, the load borne by the second joint 2 is supported on the first building 10 where the first joint 1 is located by the first pad rail 141 of the first joint 1, ensuring the flatness of the track joint and the support strength for the RGV. The number of the first pad rail 141 and the horizontal tenon 242 is not limited and can be one, two, etc. For example, when there is one first pad rail 141, there is also one second horizontal groove 243; when there are two first pad rails 141, there are also two second horizontal grooves 243.

[0074] In one embodiment, when multiple first side tenons 133 are provided, the multiple first side tenons 133 are fixedly connected to a first top tenon 131; when multiple second side tenons 233 are provided, the multiple second side tenons 233 are fixedly connected to a second top tenon 231.

[0075] In this embodiment, multiple first side tenons 133 are fixedly connected to a first top tenon 131, and multiple second side tenons 233 are fixedly connected to a second top tenon 231, which can improve the stability of the overall device.

[0076] In one embodiment, the end faces of the first end of the first track body 12 and the first end of the second track body 22 are both provided with a chamfered structure.

[0077] In this embodiment, both the first end of the first track body 12 and the end face of the first end of the first track body 12 are provided with a chamfered structure, which can reduce the wear on the RGV wheels and guide wheels at the track joint. The materials of the first joint 1 and the second joint 2 can be steel, such as high-manganese steel or other wear-resistant steel, to improve the durability of the joint device.

[0078] In one embodiment, the first support portion 11 includes a first support block 111 and a first track body 12 is disposed on the first support block 111; the second support portion 21 includes a second support block 211 and a second track body 22 is disposed on the second support block 211.

[0079] In this embodiment, the first track body 12 is supported by the first support block 111 and the second track body 22 is supported by the second support block 211, which can improve the stability of the overall device.

[0080] In one embodiment, the first support portion 11 further includes a mounting base plate 112, which is used to fix the first joint 1 to one side of the expansion joint 50 of the ground or floor, and the first support block 111 is disposed on the mounting base plate 112.

[0081] In this embodiment, the mounting base plate 112 can be fixed to one side of the expansion joint 50 on the ground or floor using bolts. It should be noted that when the first track body 12 is fixed to the ground via the mounting base plate 112, the first connector 1 is the fixed end, and the second connector 2 is the movable end. Understandably, the fixed end and the movable end can also be interchangeably installed on the building. For example, the second support part 21 includes the mounting base plate 112, which is used to fix the second connector 2 to one side of the expansion joint 50 on the ground or floor. The second support block 211 is installed on the mounting base plate 112. In this case, the second connector 2 is the fixed end, and the first connector 1 is the movable end.

[0082] In one embodiment, the first support portion 11 further includes a support plate 113, which is disposed on the mounting base plate 112, and the first support block 111 is disposed on the support plate 113.

[0083] In this embodiment, the length of the support plate 113 can be the same as the length of the mounting base plate 112 to improve the stability of the first joint 1 structure. At this time, the first horizontal groove 142 is disposed between the first pad rail 141 and the support plate 113.

[0084] Understandably, when the mounting base plate 112 is located on the second connector 2, the support plate 113 is located on the second connector 2, and the second support block 211 is set on the support plate 113.

[0085] In one embodiment, the second support portion 21 is provided with a third horizontal groove 212, and the support plate 113 is slidably connected to the third horizontal groove 212.

[0086] In this embodiment, the third horizontal groove 212 can be disposed below the second pad rail 241, and the support plate 113 is slidably connected to the third horizontal groove 212, which can improve the stability when the first connector 1 and the second connector 2 are slidably connected. The third horizontal groove 212 can be disposed below the second pad rail 241.

[0087] In one embodiment, the connector device further includes a support structure 3, which is disposed on the ground or floor to support the second connector 2.

[0088] In this embodiment, the stability of the second connector 2 can be improved by supporting the second connector 2 with the support structure 3.

[0089] In one embodiment, the support structure 3 includes a support base 31, a first limiting fastener 32, and a second limiting fastener 33. The support base 31 is disposed on the ground or floor. The first limiting fastener 32 is disposed on the support base 31 and is used to fix one end of the support base 31 to the ground or floor. The second limiting fastener 33 is disposed at intervals on one side of the first limiting fastener 32 and is used to fix the other end of the support base 31 to the ground or floor. The first limiting fastener 32 and the second limiting fastener 33 are respectively disposed on both sides of the second track body 22, and the displacement of the second track body 22 in its width direction can be restricted by the first limiting fastener 32 and the second limiting fastener 33.

[0090] In this embodiment, the support base 31 can support the second track body 22 to improve the stability of the second connector 2. The first limiting fastener 32 and the second limiting fastener 33 can both fix the support base 31 to the ground or floor and limit the displacement of the second track body 22 in its width direction to reduce the connection deviation between the second connector 2 and the first connector 1. The first limiting fastener 32 and the second limiting fastener 33 can be fastening bolts.

[0091] An exemplary embodiment of this application provides an assembly process for a connector device, wherein, in this embodiment, the first connector 1 serves as a fixed end and the second connector 2 serves as a movable end.

[0092] Before assembly, align the top and side surfaces of the second track body 22 of the second connector 2 with the top and side surfaces of the first track body 12 of the first connector 1, respectively.

[0093] During installation, the first connector 1 is fixed to one side of the expansion joint 50 on the ground or floor via the mounting base plate 112, and the second connector 2 is pulled apart by a certain preset distance. The second end of the first connector 1 is connected to the first track 20, and the second end of the second connector 2 is connected to the second track 40. The first track 20 and the second track 40 are then leveled, straightened, and fixed to their respective ground or floor surfaces. The first end of the second connector 2 is inserted into the first end of the first connector 1, so that the first end of the second connector 2 and the first end of the first connector 1 interlock to form a mortise and tenon structure, which allows for telescopic sliding.

[0094] After assembly, the contact surfaces of the first connector 1 and the second connector 2 are mutually constrained by the interlocking of the first top surface tenon 131 with the second top surface groove 232, the second top surface tenon 231 with the first top surface groove 132, the first side surface tenon 133 with the second side surface groove 234, and the second side surface tenon 233 with the first side surface groove 134, ensuring that the RGV wheels travel smoothly on the top surface of the track joint. Furthermore, the length of the first track body 12 and the second track body 22 can be extended or retracted to ensure that the first track 20 and the second track 40 are mutually straight.

[0095] In summary, the joint device of this application, through the mortise and tenon structure, ensures the straightness and smoothness of the track joint, and can also compensate for changes in the position of the two ends of the track caused by the building expansion joint 50 through sliding expansion and contraction. This joint device has a simple structure, is easy to install, and can adapt to large expansion and contraction changes, effectively solving problems in related technologies, improving the operating efficiency and stability of the RGV, and ensuring the efficiency of material transportation. Therefore, the joint device of this application has broad market demand and good application prospects.
