Detailed Implementation

[0039] To better understand the above technical solutions, exemplary embodiments of this application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0040] Referring to Figures 1 to 7, a splicing gantry for a track-carrying robot is described. The splicing gantry includes column units 10 extending along a first direction X and splicing structures 20 for fixing the two ends of a pair of column units 10 together.

[0041] The column units in Figures 1 to 4 include a second column profile and a connecting flange; the column units in Figures 5 to 7 include a first column profile.

[0042] The column unit 10 has a recessed guide groove 14 on its surface, which extends along the first direction X; the splicing structure 20 includes a positioning post 21, a positioning hole 22 for the positioning post 21 to be inserted, and a connector, which extends along the first direction X.

[0043] The positioning pin 21 and the positioning hole 22 are respectively located on the two end faces of the pair of column units 10. The two ends of the connector along the first direction X are respectively fixedly installed on the two ends of the pair of column units 10.

[0044] Furthermore, when the splicing structure 20 fixes the two ends of the pair of column units 10 together, the connector avoids the guide groove 14 so that the pair of guide grooves 14 are spliced ​​into a straight track for the transport mechanism 100 of the track transport robot to move up and down.

[0045] Overall, the splicing structure 20 in this embodiment can fix the two ends of at least one pair of column units 10 to form a splicing column. Thus, a pair of splicing columns can be arranged in parallel to form a splicing gantry, which extends the length of the splicing gantry and the working height of the track transport robot.

[0046] Of course, the splicing column can also be formed by splicing three or more column units 10 along its length. In this case, it can be understood that the ends of the column units 10 that are connected in pairs are fixedly connected by the splicing structure 20.

[0047] Specifically, the splicing structure 20 in this embodiment includes positioning holes 22, positioning posts 21, and connectors.

[0048] The positioning post 21 and the positioning hole 22 extend along the first direction, that is, along the length direction of the column unit 10. The positioning post 21 and the positioning hole 22 are respectively located on the two end faces of the pair of column units 10. Here, it can be understood that the positioning post 21 or the positioning hole 22 can be directly set on the end face of the column unit, or it can be understood that the positioning post 21 or the positioning hole 22 can also be set on the end face of the column unit 10 by other structures (such as the connecting flange described below) fixed to the end face of the column unit 10.

[0049] Then, the positioning hole 22 is used for the positioning post 21 to be inserted and installed. At this time, it can be understood that the two ends of a pair of column units 10 can be positioned and inserted by the insertion and installation of the positioning post 21 and the positioning hole 22, thereby improving the accuracy of the column unit 10 to be installed.

[0050] The connector extends along the first direction X, that is, along the length of the column unit 10. The two ends of the connector along the first direction X are respectively fixedly installed at the two ends of the pair of column units 10. Here, it can be understood that after the two ends of the pair of column units 10 are positioned and inserted through the positioning post 21 and positioning hole 22, the connector can fix the two ends of the pair of column units 10 after positioning and insertion.

[0051] In other words, for the two ends of a pair of column units 10, this embodiment first uses positioning posts 21 and positioning holes 22 to achieve positioning and insertion of the two ends, and then uses connectors to achieve fixed connection of the two ends, so that the splicing operation is simple and the splicing structure is stable.

[0052] It is understood that the purpose of the connector is to fix the two ends of the pair of column units 10 after positioning and insertion. The connector can be a single profile (the first connecting profile 231 shown in Figure 5) or a separate profile (a pair of second connecting profiles 232 shown in Figures 2 and 4). This embodiment does not limit this.

[0053] Furthermore, it is understood that the surface of the column unit 10 should be provided with a recessed guide groove 14, the guide groove 14 extends along the first direction, and after the two ends of the pair of column units 10 are fixedly installed, the pair of guide grooves 14 can be spliced ​​to form a straight track for the transport mechanism of the track transport robot to move up and down; wherein, the connector in this embodiment should avoid the guide groove 14 to avoid obstructing the up and down movement of the transport mechanism.

[0054] Specifically, it can be understood that the cross-section of the connector perpendicular to the first direction X can be, for example, L-shaped or U-shaped. Connectors with L-shaped or U-shaped cross-sections can avoid the guide groove 14. For example, the connector is an angle iron or a U-shaped channel steel. This embodiment does not limit this.

[0055] This application provides a splicing gantry for a track-carrying robot. The splicing gantry includes column units 10 and a splicing structure 20 for fixing the two ends of a pair of column units 10 together. The splicing structure 20 includes positioning posts 21, positioning holes 22, and connectors. The positioning posts 21 and positioning holes 22 are respectively located on the two end faces of the pair of column units 10. The positioning holes 22 are used for inserting and installing the positioning posts 21. Then, the two ends of the connectors along a first direction are respectively fixedly installed on the two ends of the pair of column units 10 together. In this way, the splicing structure 20 can fix the two ends of the pair of column units 10 together, or fix the pair of column units 10 along their length direction, thereby extending the height of the track-carrying robot gantry and solving the technical problem that the operating height of the track-carrying robot is limited due to the short length of the existing gantry.

[0056] Furthermore, in this embodiment, when the splicing structure 20 fixes the two ends of a pair of column units 10 together, the connector of the splicing structure 20 will avoid the guide groove 14 recessed on the surface of the column unit 10. Thus, it can be understood that a pair of guide grooves 14 can be spliced ​​to form a straight track for the transport mechanism of the track transport robot to move up and down.

[0057] Regarding the cross-section of the column unit 10, in one possible embodiment, referring to FIG6, in a plane perpendicular to the first direction X, the cross-section of the column unit 10 includes a connecting portion 11 extending along the second direction Y, the second direction Y being perpendicular to the first direction X, and a pair of guide portions 12 extending from both ends of the connecting portion 11 toward the same side, so that the space between the pair of guide portions 12 forms a concave guide groove 14.

[0058] Specifically, referring to Figure 6, the column unit 10 (specifically, the first column profile 15 in Figure 6) includes a connecting portion 11 in its cross-section perpendicular to the first direction. The connecting portion 11 extends along the second direction Y. Then, a pair of guide portions 12 extend from both ends of the connecting portion 11 toward the same side, thus forming a concave guide groove 14 in the space between the pair of guide portions 12. The extension of the connecting portion 11 along the second direction Y can be understood as the connecting portion 11 having a certain width along the second direction Y.

[0059] It is understandable that at this time, the bottom surface of the guide groove 14 (i.e. the surface of the connecting part facing the guide part) can be used for the moving wheels of the conveying mechanism to move up and down, and the side surface of the guide groove 14 (i.e. the surface opposite the guide part) can limit the movement of the moving wheels of the conveying mechanism.

[0060] In one specific embodiment, the connecting part 11 is provided with a support part 13 on the side opposite to the guide part 12; wherein, the first outer surface 131 of the support part 13 opposite to the connecting part 11 and the second outer surface 121 of at least one guide part 12 are used for fixing the connector so that the connector avoids the guide groove 14.

[0061] In this embodiment, a support portion 13 is provided on the side of the connecting portion 11 facing away from the guide portion 12 to increase the stability of the column unit 10.

[0062] In a preferred embodiment, the support portion 13 may be hollow to reduce the weight of the column unit 10.

[0063] Specifically, it can be understood that when the cross-section of the connector is L-shaped, the first outer surface 131 of the support portion 13 facing away from the connecting portion 11 and the second outer surface 121 of any one of the guide portions 12 are used for the fixed installation of the L-shaped cross-section connector; when the cross-section of the connector is U-shaped, the first outer surface 131 of the support portion 13 facing away from the connecting portion 11 and the pair of second outer surfaces 121 of the pair of guide portions 12 are used for the fixed installation of the U-shaped cross-section connector; the connector can then avoid the guide groove 14.

[0064] In one specific embodiment, the first outer surface 131 is provided with a first mounting positioning groove 132, which extends along a first direction X. The first mounting positioning groove 132 is used for positioning and installing the fastening connector and the first screw of the column unit 10.

[0065] Specifically, a first mounting positioning groove 132 extending in a first direction can be provided on the first outer surface 131 of the support portion 13 facing away from the connecting portion 11. The first mounting positioning groove 132 can position the first screw. Specifically, two first mounting positioning grooves 132 as shown in FIG6 can be provided on the first outer surface 131.

[0066] In one specific embodiment, the second outer surface 121 is provided with a second mounting positioning groove 122, which extends along the first direction X. The second mounting positioning groove 122 is used for positioning and installing the fastening connector and the second screw of the column unit 10.

[0067] Similarly, a second mounting positioning groove 122 extending along the first direction X can be specifically provided on the second outer surface 121 of the guide portion 12. The second mounting positioning groove 122 can position the second screw. For example, a second mounting positioning groove 122 as shown in FIG6 can be specifically provided on the second outer surface 121.

[0068] Of course, it is understood that in some embodiments, the first mounting positioning groove 132 may be provided only on the first outer surface 131, while the second outer surface 121 may not be provided with the second mounting positioning groove 122; or, the second mounting positioning groove 122 may be provided only on the second outer surface 121, while the first outer surface 131 may not be provided with the first mounting positioning groove 132; or, the first outer surface 131 and the second outer surface 121 may be provided with the first mounting positioning groove 132 and the second mounting positioning groove 122 at the same time.

[0069] Regarding the arrangement of the positioning post 21 and the positioning hole 22, in one possible embodiment, referring to Figures 5 to 7, the column unit 10 includes a first column profile 15 extending along the first direction X; wherein, the positioning post 21 and the positioning hole 22 are respectively disposed on the two end faces of the pair of first column profiles 15 that meet, and the connector includes a first connecting profile 231, the two ends of the first connecting profile 231 being fixed to the ends of the pair of first column profiles 15 respectively.

[0070] In this embodiment, the positioning post 21 and positioning hole 22 mentioned above can be directly set on the end face of the first column profile 15.

[0071] That is, in a pair of first column profiles 15, the positioning post 21 is provided on the end face of the mating of one of the first column profiles 15, and the positioning hole 22 is provided on the end face of the mating of the other first column profile 15.

[0072] At this point, it can be understood that the connector is a first connecting profile 231 integrally formed, and the two ends of the first connecting profile 231 can be directly fixedly installed on the ends of a pair of first column profiles 15.

[0073] Regarding the arrangement of the positioning post 21 and the positioning hole 22, in another possible embodiment, referring to Figures 1 to 4, the column unit 10 includes a second column profile 16 extending along the first direction X and a connecting flange 17 fixedly installed on the end face of the second column profile 16; wherein, the positioning post 21 and the positioning hole 22 are respectively located on the two end faces of the pair of connecting flanges 17 mating, and the connector includes a pair of second connecting profiles 232, the second connecting profiles 232 being fixedly installed on the mating ends of the second column profile 16 and fixedly installed with the connecting flanges 17; and the connector also includes flange connecting screws 30 for fixing the mating pair of connecting flanges 17.

[0074] In this embodiment, the positioning post 21 and positioning hole 22 mentioned above can be set on the connecting flange 17 that is fixedly installed on the end face of the second column profile 16.

[0075] That is, the end face of the second column profile 16 can be fastened to the connecting flange 17 first by the flange fixing screw 40. Then, in a pair of second column profiles 16, the positioning post 21 is provided at the connecting flange 17 at the end of one of the second column profiles 16, and the positioning hole 22 is provided at the connecting flange 17 at the end of the other second column profile 16.

[0076] At this point, it can be understood that the connector is a pair of separate second connecting profiles 232, each of which is used to fix a second column profile 16 to its end connecting flange 17; then, the connector also includes flange connecting screws 30 for fastening the pair of connecting flanges 17 (the connecting flange 17 is provided with flange connecting through holes 171 through which the flange connecting screws 30 pass), so that the mating ends of the pair of second column profiles 16 can be fixedly connected.

[0077] In other words, for each second column profile 16, a second connecting profile 232 is fixedly installed at its mating end, and a connecting flange 17 is fixedly installed on the end face of its mating end. The connecting flange 17 is fixedly installed with the second connecting profile 232. Furthermore, a pair of connecting flanges 17 at the mating ends of a pair of second column profiles 16 are also fixedly installed by flange connecting screws 30.

[0078] Regarding the fixed installation of the connecting flange 17 and the second connecting profile 232, in one specific embodiment, the connecting flange 17 protrudes from the cross section of the second column profile 16 in a plane perpendicular to the first direction X; wherein, the second connecting profile 232 includes a first mounting portion 2321 extending along the first direction X, and a second mounting portion 2322 perpendicular to the first direction X is provided at the end of the first mounting portion 2321 facing the connecting flange 17, and the second mounting portion 2322 is used to abut against the protruding portion of the connecting flange 17 relative to the cross section of the second column profile 16; and, flange connecting screws 30 are used to fix the mating pair of connecting flanges 17 and the pair of second mounting portions 2322.

[0079] In the plane perpendicular to the first direction X, the connecting flange 17 is convex relative to the cross section of the second column profile 16. This can be understood as the cross section profile of the connecting flange 17 being larger than the cross section profile of the second column profile 16 in the plane perpendicular to the first direction X, thereby causing the cross section profile of the connecting flange 17 to convex outward from the cross section profile of the second column profile 16.

[0080] Specifically, firstly, in a plane perpendicular to the first direction, the connecting flange 17 should be convex relative to the cross section of the second column profile 16.

[0081] Then, the second connecting profile 232 includes a first mounting portion 2321 and a second mounting portion 2322 disposed perpendicular to the connecting flange 17. The first mounting portion 2321 extends along a first direction and is used for fixed installation with the second column profile 16. The end of the first mounting portion 2321 facing the connecting flange 17 is bent vertically to form the second mounting portion 2322. The second mounting portion 2322 abuts against the portion of the connecting flange 17 that protrudes relative to the second column profile 16. Thus, by fixing the second mounting portion 2322 to the portion of the connecting flange 17 that protrudes relative to the second column profile 16, the fixed installation of the connecting flange 17 and the second connecting profile 232 can be achieved.

[0082] Furthermore, it is understood that the second mounting part 2322 and the part of the connecting flange 17 protruding from the second column profile 16 can be fixedly installed by means of the flange connecting screw 30; that is, the flange connecting screw 30 provided along the first direction X can not only fix the pair of connecting flanges 17, but also fix the pair of second mounting parts 2322 that abut against the pair of connecting flanges 17 at the same time, and the installation structure is simple.
