Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, specifically to an automatically adjustable guide wheel positioning structure. Background Technology

[0002] In many industrial and engineering applications, guide wheels are widely used to guide the movement of linear objects such as flexible pipes, steel wires, and nylon ropes. Existing guide wheel structures typically employ a fixed installation method, failing to automatically adjust their angle according to changes in the direction of force applied to the rope. When the rope's direction changes, the fixed guide wheel cannot adjust its angle in time, easily causing the rope to deviate from its intended path, affecting the normal operation of the equipment. Because the guide wheel cannot adjust with changes in rope direction, the rope is prone to tangling and knotting during movement, increasing maintenance costs and equipment downtime. Furthermore, the fixed angle of the guide wheel generates significant friction on the rope when the rope's direction changes, accelerating wear on both the rope and the guide wheel, and shortening their service life. Utility Model Content

[0003] The purpose of this invention is to provide an automatically adjustable guide wheel positioning structure, which realizes the automatic angle adjustment of the guide wheel when subjected to external force and the automatic reset after the external force disappears, ensuring that the rope always moves smoothly along the predetermined path, thus solving the problems in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An automatically adjustable guide wheel positioning structure includes a guide wheel body, which is rotatably connected to a rotating frame. The rotating frame is provided with a rotating shaft, which passes through a fixed seat and is fixedly connected to a swing rod. The swing rod is arranged horizontally, and a reset component is provided on one side of the swing rod. A limit block is fixed on the inner side wall of the fixed seat, and the limit block is located below the swing rod.

[0005] Preferably, the limiting block includes a first limiting block and a second limiting block, the first limiting block and the second limiting block are respectively located on the lower side of the rotating shaft, and the first limiting block is close to the reset assembly.

[0006] Preferably, the reset assembly includes a pull rod and a reset spring. The upper end of the pull rod has a first moving groove, and the lower end of the pull rod has a second moving groove. The pull rod, the first moving groove, and the second moving groove are all arranged longitudinally.

[0007] Preferably, a pressing rod is fixed to the end of the swing rod near the pulling rod, the pressing rod passes through the first moving groove and is slidably connected to the first moving groove; a positioning rod is fixed on the inner side wall of the fixed seat, the positioning rod passes through the second moving groove and is slidably connected to the second moving groove.

[0008] Preferably, the bottom side of the swing rod is provided with a connecting strip, and the end of the connecting strip is provided with a first connecting block.

[0009] Preferably, the swing rod is provided with a second connecting block, which is located between the rotating shaft and the pressing rod, and the two ends of the return spring are fixed to the first connecting block and the second connecting block respectively.

[0010] Preferably, the longitudinal length of the first moving groove is greater than the vertical distance from the swing rod to the second limiting block.

[0011] Preferably, the fixing base has mounting plates on both sides, and mounting holes are provided on the mounting plates.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, through the connection between the guide wheel body and the rotating frame, and the linkage between the rotating shaft and the swing rod, allows the guide wheel body to automatically adjust its angle when one end of the swing rod approaches the second limiting block. This causes the first connecting block to move upwards, stretching the return spring. When the steering pressure on the guide wheel body disappears, the return spring contracts, restoring the swing rod to its initial position, and consequently, the guide wheel body to its initial position. When one end of the swing rod approaches the first limiting block, the lowering rod pushes the pulling rod downwards, which in turn causes the first connecting block to move downwards via the connecting bar, stretching the return spring. When the steering pressure on the guide wheel body disappears, the return spring contracts, causing the pulling rod to push the swing rod upwards via the lowering rod, restoring it to its initial position. This device allows the guide wheel body to automatically adjust its angle when subjected to rope steering pressure, ensuring that the rope always moves along a predetermined path during movement, preventing the rope from deviating from the predetermined path, improving the accuracy of guidance, and thus maintaining the normal operation of the equipment.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] To address the problem in existing technologies where the guide wheel cannot rotate at a certain angle to adapt to changes in the direction of force on the rope, the following technical solution is proposed. Please refer to [link / reference needed]. Figure 1-5 ; An automatically adjustable guide wheel positioning structure includes a guide wheel body 1, which is rotatably connected to a rotating frame 2. The rotating frame 2 is provided with a rotating shaft 3, which passes through a fixed seat 4 and is fixedly connected to a swing rod 5. When the guide wheel body 1 is subjected to the turning pressure of the rope, it can rotate by itself at a certain angle to adapt to the extension direction of the rope. The guide wheel body 1 can rotate at a certain angle in two opposite directions through the rotating shaft 3.

[0017] The swing rod 5 is arranged horizontally, and a reset component is provided on one side of the swing rod 5. A first limiting block 6 and a second limiting block 16 are fixed on the inner side wall of the fixed base 4. The first limiting block 6 and the second limiting block 16 are both located below the swing rod 5, and the first limiting block 6 and the second limiting block 16 are respectively located on the oblique lower side of the rotating shaft 3. The first limiting block 6 is close to the reset component. The swing rod 5 rotates around the rotating shaft 3. The swing rod 5 is restricted by the first limiting block 6 and the second limiting block 16, so that the downward rotation angle of the swing rod 5 is limited to a certain range.

[0018] The reset assembly includes a pull rod 7 and a reset spring 8. The upper end of the pull rod 7 is provided with a first moving groove 9, and the lower end of the pull rod 7 is provided with a second moving groove 10. The pull rod 7, the first moving groove 9 and the second moving groove 10 are all arranged longitudinally, so the pull rod 7 can only move longitudinally.

[0019] A downward pressure rod 11 is fixed to the end of the swing rod 5 near the end of the pull rod 7. The downward pressure rod 11 passes through the first moving groove 9 and is slidably connected to the first moving groove 9. A positioning rod 12 is fixed on the inner side wall of the fixed base 4. The positioning rod 12 passes through the second moving groove 10 and is slidably connected to the second moving groove 10.

[0020] A connecting strip 13 is provided on the bottom side of the swing rod 5, and a first connecting block 14 is provided at the end of the connecting strip 13. A second connecting block 15 is provided on the swing rod 5. The second connecting block 15 is located between the rotating shaft 3 and the pressing rod 11. The two ends of the return spring 8 are fixed to the first connecting block 14 and the second connecting block 15 respectively. The longitudinal length of the first moving groove 9 is greater than the vertical distance from the swing rod 5 to the second limiting block 16, so that the pressing rod 11 will not drive the pulling rod 7 to move upward when it moves upward.

[0021] Mounting plates are provided on both sides of the fixed base 4, and mounting holes 17 are provided on the mounting plates to facilitate the installation of the guide wheel body 1 on the corresponding equipment.

[0022] Working principle: The guide wheel body 1 drives the rotating shaft 3 to rotate through the rotating frame 2. The rotating shaft 3 drives the swing rod 5 to rotate. When one end of the swing rod 5 approaches the second limiting block 16, the other side of the swing rod 5 drives the lowering rod 11 and the second connecting block 15 to move upward. The lowering rod 11 moves in the first moving groove 9 but does not drive the pulling rod 7. Therefore, the connecting bar 13 and the first connecting block 14 remain stationary. The second connecting block 15 moves upward, causing the return spring 8 to stretch. When the steering pressure on the guide wheel body 1 disappears, the contraction of the return spring 8 causes the swing rod 5 to return to its initial position.

[0023] When one end of the swing rod 5 approaches the first limiting block 6, the pressing rod 11 pushes the pulling rod 7 downward, which in turn drives the first connecting block 14 downward through the connecting bar 13, thereby stretching the return spring 8. When the steering pressure on the guide wheel body 1 disappears, the contraction of the return spring 8 causes the pulling rod 7 to push the swing rod 5 upward through the pressing rod 11 to return it to its initial position.
