When pressing, the open side edges of the installation slot will push the rounded edges of the two wedge blocks inward, and the two wedge blocks will slide inward in the sliding cavity when pushed and retract into the sliding cavity. When the limit block is installed in the installation slot, the two wedge blocks will be pushed out of the opening of the sliding cavity again under the action of the pushing component, and the two wedge blocks will be stuck in the side edges of the installation slot, thereby locking the limit component. At this time, the installation of the guide rail assembly base is completed; Step 2: Then install multiple sets of guide rail assemblies according to the required length. When installing, first install the limit assembly under it into the installation groove, and connect the adjacent guide rail assemblies. When connecting, pass the screw under the sidemost support plate of the guide rail assembly through the hollow sleeve under the sidemost support plate of the adjacent guide rail assembly, and use nuts to tighten the connected hollow sleeves and screws; Step 3: The rubber airbag is passed through the No. 2 fixing tube and the No. 1 fixing tube in the multiple guide rail assemblies, and then the connection angles of the multiple support plates in the guide rail assemblies can be adjusted, and then the rubber airbag is inflated by using the inflation device.

When the two connecting plates are pulled upward, the sliding rods at their bottom ends will slide upward in the guide grooves opened on the inner walls of the inclined grooves, and the two wedge blocks will shrink toward the inside of the sliding cavity. When the wedge blocks shrink into the sliding cavity, the limit blocks can be taken out from the mounting grooves, and the guide rail assembly can be disassembled and replaced.

[0015] The present invention is beneficial in that: 1. The present invention installs multiple sets of guide rail assemblies according to the required length. During installation, the limit assembly under it is first installed into the installation groove, and the adjacent guide rail assemblies are connected. When connecting, the screw under the lateral support plate of the guide rail assembly is passed through the hollow sleeve under the lateral support plate of the adjacent guide rail assembly, and the connected hollow sleeve and screw are fastened with a nut. Multiple sets of guide rail assemblies are used for splicing, and the length of the floor rail can be adjusted according to usage requirements.

[0016] 2. The present invention aligns the rounded edges of the two wedge blocks with the sides of the mounting groove and presses down. When the two wedge blocks are pushed, they slide inward in the sliding cavity. When the limit block is installed in the mounting groove, the two wedge blocks are pushed out of the opening of the sliding cavity again, and the two wedge blocks are stuck in the sides of the mounting groove, thereby locking the limit assembly. When the ground rail needs to be repaired or replaced, the rubber airbag is taken out from the No. 2 fixing cylinder and the No. 1 fixing cylinder to be replaced, and the screw is removed from the adjacent hollow sleeve. After the two wedge blocks are retracted into the sliding cavity, the limit block can be taken out from the mounting groove, and the guide rail assembly can be disassembled and replaced, which facilitates the disassembly and replacement of the ground rail. After the two wedge blocks are retracted into the sliding cavity, the limit block can be slid in the mounting groove, so that the guide rail assembly can be adjusted to the installation position in the mounting groove at will.

[0017] 3. The present invention fixes the top end of the No. 2 rotating shaft to the bottom side of one of the support plates, and the No. 2 connecting tube is fixed to the bottom side of the adjacent support plate through a fixed seat. During adjustment, the adjacent support plate will rotate in the No. 2 connecting tube under the support of the No. 2 rotating shaft, and the support plate in the middle of the guide rail assembly will rotate in the No. 1 connecting tube under the support of the No. 1 rotating shaft, so as to adjust the connection angles of multiple support plates, so that the guide rail assembly can be suitable for robot guidance with different guide angle requirements, and the ground rail assembly can be reused, avoiding the need to purchase additional ground rails when the ground rail angle needs to be adjusted in subsequent use, thereby increasing production costs.

[0018] 4. In the present invention, when the installation groove is set as an irregular curve, the guide rail assembly spliced ​​along the installation groove path can use the second rotating axis to perform adaptive rotation between multiple support plates in the second connecting tube, so that the support plates in multiple groups of guide rail assemblies can adapt to the curved path of the installation groove after being combined.

The No. 2 fixing ring 6301 and the No. 2 annular groove 6302 are used to limit the rotation of the No. 2 rotating shaft 63 to prevent the No. 2 rotating shaft 63 from escaping from the No. 2 rotating shaft 63, and the No. 2 fixing ribs 6601 and the No. 2 limiting grooves 6602 are used to limit the lifting of the No. 2 connecting rod 66 to prevent the No. 2 connecting rod 66 from rotating in the No. 2 annular fixing plate 65, so that the No. 2 rotating shaft 63 can be locked by cooperating with the No. 2 spline plug 68 and the No. 2 plum blossom slot 64.

[0033] When working, the robot ground rail is usually fixed to the ground by connecting parts and bolts during installation. This installation method requires the bolts to be removed when the ground rail needs to be replaced or maintained, which makes disassembly and assembly inconvenient. In addition, the ground rail is mostly cast or cut into pieces in one piece, and the angle of the ground rail cannot be adjusted as needed during subsequent use. Purchasing additional ground rails will increase production costs. In this solution, the pushing component 34 will always push the two wedge blocks 33 outward in the initial state, so that the rounded edges of the two wedge blocks 33 are located outside the opening of the sliding cavity 32. When in use, first open the installation groove 2 of the required angle according to the use needs, and when installing When the locking cam 31 is in the closed position, the locking cam 32 is in the closed position, and the locking cam 32 is in the closed position, so that the locking cam 32 is in the closed position and the locking cam 32 is locked. Then, multiple sets of guide rail assemblies are installed according to the required length. When installing, the limit assembly 3 under it can be installed into the installation groove 2 first, and the adjacent guide rail assemblies are connected. When connecting, the screw 10 under the support plate 5 on the most side of the guide rail assembly is passed through the hollow sleeve 9 under the support plate 5 on the most side of the adjacent guide rail assembly, and the nut 11 is used to tighten the connected hollow sleeve 9 and the screw 10. By splicing multiple sets of guide rail assemblies, the length of the ground rail can be adjusted according to the use requirements; Then adjust the angles of the multiple groups of guide rail assemblies that have been spliced ​​together so that they can be connected at the required angles. When adjusting, first insert the rubber airbag 8 that matches the length of the ground rail through the No. 2 fixing tube 61 and the No. 1 fixing tube 41 in the multiple groups of guide rail assemblies, and then adjust the connection angles of the multiple support plates 5 in the guide rail assembly. When adjusting, by twisting the support plate 5 at the most side, the support plate 5 at the side will drive the connected support plates 5 to swing in turn, and the adjacent support plates 5 will rotate in the No. 2 connecting tube 62 under the support of the No. 2 rotating shaft 63, and the support plate 5 in the middle will rotate on the No. 1 rotating shaft. 43, it rotates in the No. 1 connecting cylinder 42 to adjust the connection angles of the multiple support plates 5. When the mounting groove 2 is an irregular curve, the guide rail assembly spliced ​​along the path of the mounting groove 2 and the multiple support plates 5 can use the No. 2 rotating shaft 63 to perform adaptive rotation in the No. 2 connecting cylinder 62, so that the support plates 5 in the multiple groups of guide rail assemblies can adapt to the curved path of the mounting groove 2 after being combined. After the adjustment is completed, the rubber airbag 8 is inflated by the inflation device. After the rubber airbag 8 is inflated, it will expand in the No. 2 fixing cylinder 61 and the No. 1 fixing cylinder 41 in the multiple groups of guide rail assemblies. When the rubber airbag 8 is inflated, The second curved guard plate 69 and the first curved guard plate 47 in the second fixing cylinder 61 and the first fixing cylinder 41 will be subjected to an upward pushing force. When the first curved guard plate 47 moves upward, it will slide vertically in the first annular fixing plate 45 through the first connecting rod 46, and the first spline plug 49 at the top of the first connecting rod 46 will be inserted into the first plum blossom slot 44, thereby locking the first rotating shaft 43, so that the first rotating shaft 43 can no longer rotate in the first connecting cylinder 42, and then locking the support plate 5 in the middle of the multiple support plates 5 to prevent the support plate 5 in the middle from twisting under the action of external force during use, and when the second curved guard plate When 69 moves upward, it will slide vertically in the second annular fixing plate 65 through the second connecting rod 66, and the second spline plug 68 at the top of the second connecting rod 66 will be inserted into the second plum blossom slot 64, thereby locking the second rotating shaft 63, so that the second rotating shaft 63 cannot rotate in the second connecting tube 62. When the second rotating shaft 63 and the first rotating shaft 43 are both locked, the multiple support plates 5 can no longer be adjusted, and the adjustment angles of the multiple support plates 5 are fixed to lock the support plates 5 in the guide rail assembly at the end, thereby preventing the support plates 5 from rotating and deviating during use and affecting normal use. When the ground rail needs to be repaired or replaced, the gas in the rubber airbag 8 is first released, and the rubber airbag 8 is taken out from the No. 2 fixing cylinder 61 and No. 1 fixing cylinder 41 that need to be replaced, and the screw 10 is taken out from the adjacent hollow sleeve 9, and then the sliding sleeve 310 is pulled upward, so that the sliding sleeve 310 drives the two connecting plates 38 to move upward, and when the two connecting plates 38 are pulled upward, the sliding rods 39 at the bottom ends thereof will slide upward in the guide grooves 36 opened on the inner walls of the inclined grooves 35, and the two wedge blocks 33 will be retracted toward the inside of the sliding cavity 32. When the wedge blocks 33 are retracted into the sliding cavity 32, the limit block 31 can be taken out of the installation groove 2, and the guide rail assembly can be disassembled and replaced. When the two wedge blocks 33 are retracted into the sliding cavity 32, the limit block 31 can be slid in the installation groove 2, so that the guide rail assembly can be adjusted to the installation position in the installation groove 2 at will; The cooperation achieves the effect that the robot floor rail is easy to disassemble and assemble, and the fixed angle of the floor rail can be adjusted according to the needs of use, which effectively improves the reuse effect of the floor rail and avoids the need to purchase additional floor rails due to adjustments in use needs, thereby increasing production costs.
