Description

Technical Field

[0001] This utility model relates to the field of walking mechanism technology, and in particular to a cantilevered ground rail walking mechanism. Background Technology

[0002] The cantilevered ground rail system is an innovative industrial automation device designed to expand the working range of industrial robots and improve their efficiency and flexibility. This mechanism typically consists of two parallel ground rails that form the basic path for the robot's movement. The design of the ground rail system allows the robot to move back and forth along a predetermined straight track, thus adapting to working environments with varying lengths and load requirements. Also known as a robot ground rail or robot seventh axis, its core lies in achieving autonomous robot movement on the ground through a sophisticated mechanical structure and control system.

[0003] While ground-rail walking mechanisms play a vital role in industrial automation, existing technologies still present some challenges. Particularly in cantilever ground-rail walking mechanisms, the moving plate is supported only by the ground rails at both ends, lacking sufficient support in the middle, resulting in poor load-bearing capacity. This can limit the robot's movement speed and payload capacity, and even affect the stability and safety of the entire system. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a cantilevered ground rail traveling mechanism to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a cantilevered ground rail traveling mechanism, including two symmetrically arranged guide rails. Side plates are bolted to both ends of the two guide rails. A splicing plate is disposed between the two guide rails. A plurality of linearly arrayed clamping plates are fixedly connected to the front and rear sides of the splicing plate. The front and rear sides of the splicing plate are clamped to the two guide rails via the clamping plates. A sliding support is slidably connected to the top of each guide rail. A bearing plate is fixedly connected between the two sliding supports. The bearing plate is parallel to the splicing plate. A motor is fixedly connected to the top surface of the bearing plate. A gear is fixedly connected to the output end of the motor, and a rack is fixedly connected to one side of the guide rail. The gear and rack mesh with each other. An assembly plate is fixedly installed on the bottom of the bearing plate by bolts. Several linear array rotating frames are fixedly connected to the bottom surface of the assembly plate. A support roller is rotatably connected inside each rotating frame. The outer surfaces of the several support rollers are all in contact with the top surface of the splicing plate. Two connecting plates are fixedly connected to the bottom surface of the assembly plate. A cleaning brush is fixedly connected to the bottom end of each connecting plate. The cleaning brush is slidably connected to the splicing plate. The several support rollers are all located between the two cleaning brushes.

[0007] Preferably, in any of the above solutions, the bottom surface of the support plate is fixedly connected with a number of symmetrically arranged positioning pins, and the assembly plate is engaged with the support plate by the number of positioning pins.

[0008] Preferably, in any of the above embodiments, two symmetrically arranged reinforcing ribs are fixedly connected to the side of the connecting plate near the support roller, and the tops of the two reinforcing ribs are fixedly connected to the assembly plate.

[0009] Preferably, in any of the above schemes, each side plate is fixedly connected to two symmetrically arranged rubber pillars on the side near the guide rail, and several of the rubber pillars correspond to the bearing plate.

[0010] Preferably, each of the above solutions has a plurality of linear array slots on the side of the guide rail near the splicing plate, and the slots are engaged with the guide rail.

[0011] Preferably, in any of the above embodiments, the bottom surface of the splicing plate is fixedly connected with a plurality of linear array pads, the bottom surface of the pads and the bottom surface of the guide rails are on the same horizontal plane, and the distance between the two guide rails is equal to the width of the splicing plate.

[0012] Preferably, one side of the side plate is provided with a clearance groove, which corresponds to the cleaning brush.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] When installing the walking mechanism, insert the clamps on the front and rear sides of the splicing plate into the slots inside the guide rails. Then, use bolts to lock the two guide rails to the ground. Next, install the two sliding supports on the two guide rails. At this time, the outer surfaces of the support rollers are in contact with the top surface of the splicing plate. Finally, install the cantilever robotic arm on the load-bearing plate with bolts, turn on the motor to drive the gears to rotate, and through meshing transmission, the load-bearing plate can be moved. This can drive several support rollers to roll on the top of the splicing plate, supporting the middle part without affecting the displacement of the load-bearing plate, greatly improving the load-bearing capacity of the load-bearing plate. Moreover, when the load-bearing plate moves, it can drive the cleaning brush to move as well. At this time, the bottom of the cleaning brush will slide relative to the splicing plate to facilitate the cleaning of dust on the top of the splicing plate. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0022] like Figures 1 to 5As shown, a cantilevered ground rail traveling mechanism includes two symmetrically arranged guide rails 1. Side plates 2 are bolted to both ends of the two guide rails 1. A splicing plate 3 is positioned between the two guide rails 1. Several linearly arrayed clamping plates 4 are fixedly connected to the front and rear sides of the splicing plate 3, and the front and rear sides of the splicing plate 3 are engaged with the two guide rails 1 via the clamping plates 4. A sliding support 5 is slidably connected to the top of each guide rail 1. A bearing plate 6 is fixedly connected between two sliding supports 5, and the bearing plate 6 is parallel to the splicing plate 3. A motor 7 is fixedly connected to the top surface of the bearing plate 6, and a gear 8 is fixedly connected to the output end of the motor 7. A rack 9 is fixedly connected to one side of the guide rail 1. A gear 8 meshes with the rack 9. An assembly plate 10 is fixedly installed on the bottom of the bearing plate 6 by bolts. Several linear array rotating frames 11 are fixedly connected to the bottom surface of the assembly plate 10. A support roller 12 is rotatably connected inside each rotating frame 11. The outer surfaces of several support rollers 12 are all in contact with the top surface of the splicing plate 3. Two connecting plates 13 are fixedly connected to the bottom surface of the assembly plate 10. A cleaning brush 14 is fixedly connected to the bottom end of each connecting plate 13. The cleaning brush 14 is slidably connected to the splicing plate 3. Several support rollers 12 are all located between two cleaning brushes 14.

[0023] As an optional technical solution of this utility model, the bottom surface of the support plate 6 is fixedly connected with a number of symmetrically arranged positioning pins 15. The assembly plate 10 is engaged with the support plate 6 through the number of positioning pins 15. The symmetrical arrangement of the positioning pins 15 enables the assembly plate 10 to be quickly and accurately connected to the support plate 6, improving installation efficiency and positioning accuracy. This design ensures a stable connection between the support plate 6 and the assembly plate 10, enhancing the stability of the overall structure.

[0024] As an optional technical solution of this utility model, two symmetrically arranged reinforcing ribs 16 are fixedly connected to the side of the connecting plate 13 near the support roller 12. The tops of the two reinforcing ribs 16 are fixedly connected to the assembly plate 10. The reinforcing ribs 16 are symmetrically arranged between the connecting plate 13 and the assembly plate 10, which enhances the strength and rigidity of the connection part and prevents structural deformation or damage due to excessive load. This design improves the load-bearing capacity and service life of the cantilevered ground rail traveling mechanism.

[0025] As an optional technical solution of this utility model, each side plate 2 is fixedly connected to two symmetrically arranged rubber pillars 17 on the side near the guide rail 1. Several rubber pillars 17 correspond to the bearing plate 6. The rubber pillars 17 are symmetrically arranged between the side plate 2 and the bearing plate 6, serving as buffers and shock absorbers, reducing vibration and noise generated during operation. Simultaneously, the rubber pillars 17 also protect the side plate 2 and the bearing plate 6, preventing wear caused by direct contact.

[0026] As an optional technical solution of this utility model, each guide rail 1 has several linearly arrayed slots 18 on the side near the splicing plate 3. The locking plate 4 is engaged with the guide rail 1 through the slots 18. The linear array design of the slots 18 enables the locking plate 4 to be quickly and securely connected to the guide rail 1, improving the installation efficiency and stability of the guide rail 1. This design ensures that the guide rail 1 will not shift or loosen during operation, enhancing the overall reliability of the mechanism.

[0027] As an optional technical solution of this utility model, a plurality of linearly arrayed pads 19 are fixedly connected to the bottom surface of the splicing plate 3. The bottom surface of the pads 19 is on the same horizontal plane as the bottom surface of the guide rail 1, and the spacing between two guide rails 1 is equal to the width of the splicing plate 3. The linear array design of the pads 19 makes the connection between the splicing plate 3 and the guide rail 1 more stable. At the same time, the bottom surface of the pads 19 and the bottom surface of the guide rail 1 remain on the same horizontal plane, ensuring the smooth operation of the mechanism. This design also simplifies the installation and adjustment process of the guide rail 1 and improves construction efficiency.

[0028] As an optional technical solution of this utility model, a clearance groove 20 is provided through one side of the side plate 2, which corresponds to the cleaning brush 14. The clearance groove 20 and the cleaning brush 14 provide sufficient movement space for the cleaning brush 14, ensuring that it can effectively clean the debris on the surface of the guide rail 1. This design improves the ease of maintenance of the mechanism and extends the service life of the guide rail 1.

[0029] A cantilevered ground rail traveling mechanism, the working principle of which is as follows:

[0030] 1): When the walking mechanism needs to be installed, the card plates 4 set on the front and rear sides of the splicing plate 3 can be inserted into the card slots 18 inside the guide rail 1, and then the two guide rails 1 can be locked to the ground with bolts.

[0031] 2): Install the two slides 5 on the two guide rails 1. At this time, the outer surface of the support roller 12 is in contact with the top surface of the splicing plate 3. Finally, install the cantilever robotic arm on the bearing plate 6 with bolts.

[0032] 3): Turn on the motor 7 to drive the gear 8 to rotate. Through meshing transmission, the bearing plate 6 can be moved, and several support rollers 13 can be driven to roll on the top of the splicing plate 3. The middle part of the bearing plate 6 can be supported without affecting its displacement.

[0033] In summary, when installing the cantilevered ground rail walking mechanism, the clamping plates 4 set on the front and rear sides of the splicing plate 3 can be inserted into the clamping slots 18 on the inner side of the guide rail 1. Then, the two guide rails 1 are locked to the ground with bolts. Then, the two sliding brackets 5 are installed on the two guide rails 1. At this time, the outer surface of the support rollers 12 is in contact with the top surface of the splicing plate 3. Finally, the cantilevered mechanical arm is installed on the bearing plate 6 with bolts. The motor 7 is turned on to drive the gear 8 to rotate. Through meshing transmission, the bearing plate 6 can be moved, and several support rollers 13 can be driven to roll on the top of the splicing plate 3. Without affecting the displacement of the bearing plate 6, the middle part can be supported, which greatly improves the bearing capacity of the bearing plate 6. Moreover, when the bearing plate 6 moves, the cleaning brush 14 can move with it. At this time, the bottom of the cleaning brush 14 will slide relative to the splicing plate 3 to clean the dust on the top of the splicing plate 3.
