Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission equipment technology, specifically a track drive structure. Background Technology

[0002] In existing chain drive structures, most employ a simple gear meshing method, where the chain is simply fitted onto the gear. However, this sprocket drive method requires gear meshing, resulting in a complex overall structure, high cost, and difficult maintenance. Furthermore, it struggles to meet the demands for flexible transmission in certain special operating conditions. To address these issues, a cable drive method has emerged, such as... Figure 1 The system uses belt-driven cable transmission. However, in some applications where two or more track links are needed for coupled action, there is currently no drive structure specifically designed for multi-track coupled transmission.

[0003] Therefore, this patent application is filed. Utility Model Content

[0024] Currently, in industrial production, a single track is often used for conveying, such as... Figure 1 As shown, a belt-driven cable system is used for propulsion. However, in some scenarios, two or more tracks are required for coupled transmission, necessitating the driving of these tracks.

[0025] This utility model provides a track drive structure, and the following is a further detailed description of the utility model with reference to the accompanying drawings.

[0026] Please see Figure 2-4 This utility model provides a technical solution:

[0027] A track drive structure includes two tracks, namely an upper track 1 and a lower track 2, which need to be coupled for transmission.

[0028] Specifically, such as Figure 2As shown, the drive structure includes a first spool 3, a second spool 4, a first rope 5, and a second rope 6. The first rope 5 is wound around the first spool 3, and both ends of the first rope 5 are respectively connected to the first ends of the upper track 1 and the lower track 2. The second rope 6 is wound around the second spool 4, and both ends of the second rope 6 are respectively connected to the first ends of the upper track 1 and the lower track 2. The other ends of the upper track 1 and the lower track 2, i.e., the second ends, are connected to other connecting bodies.

[0029] The connection points of the two ends of the first rope 5 with the upper and lower chain rails 1 and 2 at the first end do not coincide with the connection points of the two ends of the second rope 6 with the upper and lower chain rails 1 and 2 at the first end. Furthermore, the first pulley 3 and the second pulley 4 are located between the upper and lower chain rails 1 and 2, and are arranged alternately in the vertical direction.

[0030] In use, the connector pulls the upper track 1, and the movement of the upper track 1 moves the second rope 6, which in turn moves the lower track 2 and the first rope 5 in the opposite direction. This allows the upper and lower tracks 2 to move synchronously and in a coordinated manner, thus meeting the transmission requirements of this type of track.

[0031] Furthermore, such as Figure 2 As shown, the second spool 4 is flush with the upper chain rail 1 in the horizontal direction, and the first spool 3 is flush with the lower chain rail 2 in the horizontal direction. The advantage of this design is that it can reduce slippage between the spool and the corresponding rope due to the large holding force when the upper and lower chain rails 2 move together.

[0032] Furthermore, to further reduce slippage between the rope and the reel and to ensure better contact between them, this embodiment designs both the first reel 3 and the second reel 4 to have grooves 7 in the middle, forming grooved reels. The first rope 5 is in contact with the groove 7 on the first reel 3, and the second rope 6 is in contact with the groove 7 on the second reel 4. Even better, an anti-slip structure is provided on the surface of the grooves 7 of the first reel 3 and the second reel 4, such as an uneven anti-slip texture 8. This anti-slip texture 8 allows the rope to fit tightly against the surface of the reel during transmission, reducing slippage and increasing the friction between the rope and the reel, thus improving transmission efficiency.

[0033] Furthermore, in this embodiment, a wear-resistant rope material is selected, such as aramid fiber rope as the first rope 5 and the second rope 6. This design can effectively reduce the mutual wear between the reel and the rope, and extend the service life of both.

[0034] Therefore, in this embodiment, by reasonably designing the connection and cooperation relationship between the first pulley 3, the second pulley 4, the first rope 5, the second rope 6, and the upper track 1 and the lower track 2, synchronous reverse coupling movement between the upper and lower tracks can be achieved, which is suitable for multi-track coupling work scenarios.

[0035] Furthermore, this embodiment also considers the issues of slippage and wear resistance during the drive process of the track. By setting anti-slip texture 8 and selecting special materials for the rope, slippage is reduced, transmission efficiency is improved, wear is reduced, and service life is extended.

[0036] Example 2:

[0037] This embodiment is an improvement based on Embodiment 1.

[0038] Specifically, the track drive mechanism also includes a lubrication mechanism, which comprises a delivery pipe 9 and a lubrication head 10. The lubrication head 10 is fixed to one end of the delivery pipe 9, and its end extends to the first spool 3 and the second spool 4. The other end of the delivery pipe 9 is connected to a lubricating oil storage tank, and the lubrication head 10 is a hollow cylindrical structure. In use, lubricating oil is delivered to the first spool 3 and the second spool 4 through the delivery pipe 9. This allows for periodic lubrication of the connection between the spools and the rope, further reducing wear between the spools and the rope.

[0039] Furthermore, the diameter of the hole at one end of the lubrication head 10 near the first spool 3 and the second spool 4 is designed to be smaller than the diameter at the other end, so that the lubricating oil can flow more smoothly to the end of the lubrication head 10 during lubrication.

[0040] In this embodiment, the lubrication head 10 is also designed with multiple filter holes 11 at the end with a smaller aperture (i.e., the end closer to the reel). Each filter hole 11 is evenly distributed along the axial direction of the lubrication head 10, which can not only make the lubricating oil more evenly distributed to the reel and the rope, but also play a certain filtering role to prevent impurities or possible dirt from entering between the reel and the rope and affecting the drive.

[0041] Better yet, in this embodiment, the lubrication head 10 and the delivery pipe 9 are designed to be detachable, which facilitates the maintenance or replacement of the lubrication head 10 and the delivery pipe 9.

[0042] The present invention has been described in detail above through specific embodiments and examples, but these are not intended to limit the present invention. Many modifications and improvements can be made by those skilled in the art without departing from the principles of the present invention, and these should also be considered within the scope of protection of the present invention.
