DETAILED DESCRIPTION

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figures 1 to 6 As shown, a connecting assembly for a walking mechanism includes two connecting rods 1. The front and rear sides of the top of the connecting rods 1 are threaded with linearly distributed fixing bolts 10. The lower inner surface of the connecting rods 1 is provided with toothed grooves 11 near the front and rear sides. The walking mechanism 2 is movably connected to the inner side of the right connecting rod 1. The lower surface of the walking mechanism 2 is fixedly connected to a hoisting mechanism 3.

[0029] The walking mechanism 2 includes a connecting block 20. The inner side of the connecting block 20 is movably connected to the inner sides of the front and rear sides of the right connecting rod 1. The first servo motor 21 is fixedly connected to the front and rear sides of the connecting block 20 near the left and right sides. The output end of the first servo motor 21 is fixedly connected to a gear 22, and the outer ring of the gear 22 is meshed with the outer surface of the tooth groove 11.

[0030] The hoisting mechanism 3 includes two winding rods 30. The left and right sides of the two winding rods 30 are rotatably connected to the bottom of the connecting block 20. The left side of the rear winding rod 30 and the right side of the front winding rod 30 are fixedly connected to a second servo motor 31. The outer surface of the winding rod 30 is fixedly connected to the left and right sides. The top of the middle part of the traction rope 32 is connected to a movable pulley 33. The opposite side of the movable pulley 33 is fixedly connected to a fixing block 34. The bottom of the fixing block 34 is fixedly connected to a hook 35.

[0031] When the traveling mechanism needs to transport heavy objects, the heavy object is first hung in the hook 35. Then, the second servo motor 31 is powered on, which drives the winding rod 30 to rotate. The rotation of the winding rod 30 winds up the traction rope 32. After the traction rope 32 is wound up, it drives the bottom pulley 33 to rise. The rise of the pulley 33 drives the fixed block 34 and the hook 35 to rise, thereby hoisting the heavy object. Then, the first servo motor 21 is powered on. The output end of the first servo motor 21 drives the gear 22 to rotate, so that the gear 22 meshes with the tooth groove 11. The rotation of the gear 22 moves within the connecting rod 1. The movement of the gear 22 drives the connecting block 20 to move, which in turn moves the bottom hoisting mechanism 3 and the heavy object, thereby transporting the heavy object.

[0032] like Figure 2 and Figure 3 As shown, a first limiting block 14 is fixedly connected to the upper inner side of the connecting rod 1 near the front and back, and the top of the first limiting block 14 overlaps the top of the inner side of the connecting block 20.

[0033] In the process of moving the connecting block 20, the position of the top of the inner side of the connecting block 20 is clamped into the first limiting block 14, and then the first limiting block 14 makes the top of the connecting block 20 fit in the connecting rod 1.

[0034] As shown in Figure 2 and Figure 3 , the inner side of the connecting rod 1 is fixedly connected with the second limiting block 15 near the front and rear positions in the middle and lower positions, and the top of the opposite surface of the gear 22 is overlapped on the bottom of the second limiting block 15.

[0035] In the process of rotating the gear 22, the top of the opposite surface of the gear 22 rotates on the bottom of the second limiting block 15, and then the rotation of the gear 22 cooperates with the movement of the connecting block 20, thereby reducing the friction generated by the movement of the connecting block 20 and the connecting rod 1.

[0036] As shown in Figure 4 , the bottom of the inner side of the connecting block 20 is rotatably connected with the roller 23, and the outer ring of the roller 23 is overlapped on the lower surface of the connecting rod 1.

[0037] In the process of moving the connecting block 20, the roller 23 on the top of the connecting block 20 rotates, and then cooperates with the movement of the connecting block 20 to rotate on the bottom of the connecting rod 1, thereby reducing the friction generated by the bottom of the inner side of the connecting block 20 and the bottom of the connecting rod 1.

[0038] As shown in Figure 2 and Figure 3 , the side of the connecting rod 1 far apart is overlapped with the fixed plate 12, and the middle part of the opposite side of the connecting rod 1 near the front and rear positions is overlapped with the connecting plate 13.

[0039] The fixed plate 12 can be fixed to the two sides of the connecting rod 1 by bolts, thereby limiting the maximum activity range of the connecting block 20 in the connecting rod 1, and the connecting plate 13 can splice multiple connecting rods 1, and after splicing multiple connecting rods 1, the maximum activity range of the connecting block 20 is expanded.

[0040] As shown in Figure 5 , the lower surface of the connecting block 20 is fixedly connected with the fixed pulley 36 near the four corners, and the outer surface of the traction rope 32 is overlapped on the inner side of the fixed pulley 36.

[0041] When the winding rod 30 winds the traction rope 32, the traction rope 32 moves on the top of the fixed pulley 36, so that the rotation of the fixed pulley 36 winds the traction rope 32.

[0042] As shown in Figure 5 , the position near the bottom of the front and rear sides of the connecting block 20 is fixedly connected with the protective plate 24, and the bottom of the protective plate 24 is overlapped on the outer surface of the first servo motor 21.

[0043] The guard plate 24 can guard the outer surface of the first servo motor 21, avoid the first servo motor 21 from colliding with other articles in the moving process of the connecting block 20, and avoid the damage of the first servo motor 21.

[0044] The working principle of the utility model is: when it is needed to make the walking mechanism transport the heavy object, first, the heavy object is hung in the hook 35, at this time, the second servo motor 31 is used to wind the traction rope 32, and then the traction rope 32 drives the hook 35 and the heavy object to be lifted, at this time, the first servo motor 21 drives the gear 22 to rotate, the gear 22 is engaged with the gear slot 11, and then the gear 22 drives the connecting block 20 to move, and then the walking mechanism 2 and the hoisting mechanism 3 drive the heavy object at the bottom to move, so that the transportation of the heavy object is completed.

[0045] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above. The skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments, and the above-mentioned embodiments and the description in the specification are only to illustrate the principle of the utility model, and the utility model can have various changes and improvements without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed. The protection scope of the utility model is defined by the appended claims and their equivalents.
