Description

Technical Field

[0001] This utility model relates to the field of wire rope traction structure technology, specifically a traction structure for wire rope cutting. Background Technology

[0002] To ensure that the wire rope is cut to a relatively precise length, a traction device is usually used to pull it to the designated cutting position. The traction structure allows the wire rope to maintain a certain tension under the traction force, thus keeping it taut and straight.

[0003] Most existing low-cost traction structures typically require marking the cutting position on the wire rope using measuring methods, followed by marking a straight line using a marking tool. The traction structure then pulls the wire rope to the designated position for cutting. However, this method is cumbersome and prone to error. First, measuring and marking the cutting point on the wire rope with a ruler is tedious and time-consuming, and also introduces errors. Second, the user needs to visually determine whether the marked point has reached the cutting point, and even when the point is observed to have been reached, the traction device may not be shut off in time, resulting in significant errors. Therefore, to address these issues, a traction structure for wire rope cutting is proposed. Utility Model Content

[0004] The technical problem this invention aims to solve is to provide a traction structure for wire rope cutting. In this traction structure, a sliding baffle mechanism limits the maximum sliding stroke of the traction slide, i.e., the maximum traction distance of the wire rope, which is also the cutting length. Based on this principle, a stroke reference mechanism reads the displacement of the sliding baffle mechanism, facilitating precise adjustment of its position. This eliminates the need to mark points on the wire rope with rulers, simplifying operation and reducing errors. Furthermore, when the traction length is reached, the sliding baffle mechanism prevents further movement, eliminating the need for manual judgment of the stop position. To further reduce errors, the drive motor and the transmission screw are connected by a friction drive. When the traction slide is blocked by the sliding baffle mechanism and cannot move, the friction drive slips due to friction and stops outputting torque. At this time, the transmission screw stops rotating. This connection method can prevent the drive motor from being damaged due to obstruction when the traction slide is blocked. It solves the technical problems of the existing technology, which uses a ruler to measure and mark the cutting point on the wire rope, which is cumbersome and has errors, and requires visual judgment to determine whether the marked point has reached the cutting point, which has a significant error.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] A traction structure for wire rope cutting includes a base plate on which two sets of parallel guide rails are fixedly mounted. A traction slide is slidably disposed in the guide rails, and a wire rope clamp for holding the wire rope is installed on the slide. A sliding baffle mechanism is slidably mounted on the guide rails to limit the maximum sliding stroke of the traction slide. A stroke reference mechanism is used to read the displacement of the sliding baffle mechanism. A drive motor is mounted on the base plate, and a transmission screw is disposed between the two sets of guide rails, passing through the traction slide and threadedly connected to it. The maximum sliding stroke of the traction slide, i.e., the maximum traction distance of the wire rope, or the cutting length, is limited by the sliding baffle mechanism. Based on the above principle, the displacement of the sliding baffle mechanism is read by the stroke reference mechanism, which facilitates precise adjustment of the sliding baffle mechanism's position. There is no need to use a ruler to mark points on the wire rope, simplifying the operation and reducing errors. Furthermore, when the traction length is reached, the traction slide will be unable to move further due to the obstruction of the sliding baffle mechanism, eliminating the need for manual judgment of the stopping position and further reducing errors.

[0007] Furthermore, the output shaft of the drive motor and the transmission lead screw are connected by a friction drive. Based on the above structure, when the traction slide is blocked by the sliding baffle mechanism and cannot move, the friction drive slips against the friction force and no longer outputs torque. At this time, the transmission lead screw stops rotating. This connection method can prevent the drive motor from being damaged due to obstruction after the traction slide is blocked.

[0008] In one possible implementation, the sliding baffle mechanism includes a gate-shaped baffle and a locking guide plate fixedly disposed on the outside of the guide rail plate. The locking guide plate has a locking groove, in which a locking threaded component for locking the gate-shaped baffle is slidably disposed. The gate-shaped baffle can slide along the guide rail plate to change its position, thereby adjusting the maximum sliding stroke of the traction slide. After adjustment, the position of the gate-shaped baffle can be fixed by the cooperation of the locking threaded component and the locking guide plate.

[0009] In one possible implementation, the locking threaded component includes a locking plate and a locking bolt. The locking plate is slidably disposed in a locking groove, and the locking bolt is threadedly connected to the gate-shaped baffle. The end of the locking bolt is rotatably connected to the locking plate. However, when it is necessary to fix the position of the gate-shaped baffle, the locking bolt is turned, and its inner end will move outward, thereby making the locking plate and the locking guide plate fit tightly together and generating significant friction, thus completing the fixation of the position of the gate-shaped baffle.

[0010] In one possible implementation, the travel reference mechanism includes a pointer and a scale plate. The pointer is fixedly mounted on the gate-shaped baffle, and the scale plate has scale lines. The pointer points to the scale lines. When the position of the gate-shaped baffle is adjusted, it will drive the pointer to move synchronously. The user can determine the current position of the gate-shaped baffle by the change in the value of the scale line corresponding to the pointer, thereby facilitating the user to adjust the position more accurately.

[0011] In one possible implementation, the friction drive includes a transmission cylinder fixedly connected to the output shaft of the drive motor, and a transmission shaft fixedly connected to the transmission lead screw. The inner wall of the transmission cylinder is provided with an inner friction pad, and the transmission shaft is fitted with an outer friction sleeve. The inner friction pad and the outer friction sleeve are in contact. When the traction slide moves without obstruction, the friction between the inner friction pad and the outer friction sleeve can play a transmission role, thereby transmitting torque and causing the transmission lead screw to rotate. When the traction slide is obstructed and cannot continue to move, the transmission lead screw can no longer rotate. At this time, the operation of the drive motor will drive the inner friction pad and the outer friction sleeve to rotate relative to each other, preventing the drive motor from burning out and giving the operator enough time to shut down the drive motor.

[0012] In one possible implementation, the wire rope clamp includes an L-shaped gantry fixedly mounted on a base, with a lower clamping plate fixedly mounted on the upper surface of the base. An adjusting screw is threaded onto the L-shaped gantry, and an upper clamping plate is rotatably connected to its bottom end. Both the lower and upper clamping plates have clamping grooves. By rotating the adjusting screw, the upper clamping plate can be driven to move up and down, thereby changing the distance between the upper and lower clamping plates, thus completing the clamping and fixing of wire ropes of different sizes.

[0013] In one possible implementation, a guide rod is fixedly provided on the lower clamping plate, and a corresponding guide hole is provided on the upper clamping plate. The guide rod is slidably disposed in the guide hole. The guide rod can guide the upper clamping plate to slide up and down, so that it cannot rotate when it moves, thus avoiding deflection during the movement and failure to perform the clamping function.

[0014] In one possible implementation, a guide ridge is fixedly provided on the inner wall of the guide rail plate, and guide grooves matching the size of the guide ridge are fixedly provided on both sides of the traction slide. The above structure can guide and limit the sliding of the traction slide, preventing the traction slide from deviating during the sliding process.

[0015] In summary, this utility model has the following beneficial technical effects:

[0016] In this wire rope traction structure, the maximum sliding stroke of the traction slide is limited by the sliding baffle mechanism, which is the maximum traction distance of the wire rope, or the cutting length. Based on the above principle, the displacement of the sliding baffle mechanism is read by the stroke reference mechanism, which facilitates precise adjustment of the position of the sliding baffle mechanism. There is no need to use a ruler to mark the position on the wire rope, which simplifies the operation and reduces the error. When the traction length is reached, the traction slide will be unable to move further due to the obstruction of the sliding baffle mechanism, eliminating the need for manual judgment of the stopping position and further reducing the error.

[0017] In addition, the drive motor and the transmission screw are connected by a friction drive. When the traction slide is blocked by the sliding baffle mechanism and cannot move, the friction drive slips against the friction force and stops outputting torque. At this time, the transmission screw stops rotating. This connection method can prevent the drive motor from being damaged due to obstruction when the traction slide is blocked.

[0025] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0026] like Figure 1As shown, this embodiment provides a traction structure for cutting steel wire rope, including a base plate 1 on which two sets of parallel guide rails 2 are fixedly mounted. A traction slide 3 is slidably mounted in the guide rails 2, on which a steel wire rope clamp 4 for holding the steel wire rope is installed. A sliding baffle mechanism 5 is slidably mounted on the guide rails 2 to limit the maximum sliding stroke of the traction slide 3. A stroke reference mechanism 6 is used to read the displacement of the sliding baffle mechanism 5. A drive motor 7 is mounted on the base plate 1, and a transmission screw 9 is provided between the two sets of guide rails 2, which passes through the traction slide. Platform 3 is threadedly connected to it, and the maximum sliding stroke of the traction slide 3 is limited by the sliding baffle mechanism 5, which is the maximum traction distance of the wire rope, or the cutting length. Based on the above principle, the displacement of the sliding baffle mechanism 5 is read by the stroke reference mechanism 6, which facilitates precise adjustment of the position of the sliding baffle mechanism 5. There is no need to use a ruler to mark the position on the wire rope, which simplifies the operation and reduces the error. When the traction length is reached, the traction slide 3 will be unable to move further due to the obstruction of the sliding baffle mechanism 5, eliminating the need for manual judgment of the stopping position and further reducing the error.

[0027] In addition, the output shaft of the drive motor 7 and the transmission screw 9 are connected by a friction drive 8. Based on the above structure, when the traction slide 3 is blocked by the sliding baffle mechanism 5 and cannot move, the friction drive 8 slips against the friction force and no longer outputs torque. At this time, the transmission screw 9 stops rotating. This connection method can prevent the drive motor 7 from being blocked and damaged after the traction slide 3 is blocked.

[0028] like Figure 2 - Figure 3 As shown, the sliding baffle mechanism 5 includes a portal-shaped baffle 51 and a locking guide plate 52 fixedly disposed on the outside of the guide rail plate 2. The locking guide plate 52 has a locking groove 53, in which a locking threaded component 54 for locking the portal-shaped baffle 51 is slidably disposed. The portal-shaped baffle 51 can slide along the guide rail plate 2 to change its position, thereby adjusting the maximum sliding stroke of the traction slide 3. After adjustment, the position of the portal-shaped baffle 51 can be fixed by the cooperation of the locking threaded component 54 and the locking guide plate 52. The locking threaded component... 54 includes a locking piece 541 and a locking bolt 542. The locking piece 541 is slidably disposed in the locking groove 53. The locking bolt 542 is threadedly connected to the gate-shaped baffle 51, and the end of the locking bolt 542 is rotatably connected to the locking piece 541. However, when it is necessary to fix the position of the gate-shaped baffle 51, the locking bolt 542 is turned, and its inner end will move outward, thereby making the locking piece 541 and the locking guide plate 52 fit tightly and generate significant friction, thus completing the fixation of the position of the gate-shaped baffle 51.

[0029] like Figure 2As shown, the travel reference mechanism 6 includes a pointer 61 and a scale plate 62. The pointer 61 is fixedly mounted on the gate-shaped baffle 51, and the scale plate 62 has a scale line 63. The pointer 61 points to the scale line 63. When the position of the gate-shaped baffle 51 is adjusted, it will drive the pointer 61 to move synchronously. The user can determine the current position of the gate-shaped baffle 51 by the change in the value of the scale line 63 corresponding to the pointer 61, which makes it easier for the user to adjust the position more accurately.

[0030] like Figure 5 As shown, the friction drive 8 includes a transmission cylinder 81 fixedly connected to the output shaft of the drive motor 7, and a transmission shaft 83 fixedly connected to the transmission lead screw 9. The inner wall of the transmission cylinder 81 is provided with an inner friction pad 82, and the transmission shaft 83 is covered with an outer friction sleeve 84. The inner friction pad 82 and the outer friction sleeve 84 are in contact. When the traction slide 3 moves without obstruction, the friction between the inner friction pad 82 and the outer friction sleeve 84 can play a transmission role, thereby transmitting torque and causing the transmission lead screw 9 to rotate. When the traction slide 3 is obstructed and cannot continue to move, the transmission lead screw 9 can no longer rotate. At this time, the operation of the drive motor 7 will drive the inner friction pad 82 and the outer friction sleeve 84 to rotate relative to each other, preventing the drive motor 7 from burning out and giving the operator enough time to shut off the drive motor 7.

[0031] like Figure 4 As shown, the wire rope clamp 4 includes an L-shaped gantry 42 fixedly mounted on a base 41, and a lower clamping plate 43 fixedly mounted on the upper surface of the base 41. An adjusting screw 44 is threaded onto the L-shaped gantry 42, and an upper clamping plate 45 is rotatably connected to its bottom end. Both the lower clamping plate 43 and the upper clamping plate 45 have clamping grooves 46. By rotating the adjusting screw 44, the upper clamping plate 45 can be driven to move up and down, thereby changing the distance between the upper clamping plate 45 and the lower clamping plate 43, thus completing the clamping and fixing work for wire ropes of different sizes. A guide rod 47 is fixedly mounted on the lower clamping plate 43, and a corresponding guide hole is opened on the upper clamping plate 45. The guide rod 47 is slidably mounted in the guide hole. The guide rod 47 can guide the upper clamping plate 45 to slide up and down, so that it cannot rotate when moving, avoiding deflection during movement and failure to perform the clamping function.

[0032] like Figure 3 - Figure 4 As shown, a guide rib 21 is fixedly provided on the inner wall of the guide rail plate 2, and guide grooves 31 with the same size as the guide rib 21 are fixedly provided on both sides of the traction slide 3. The above structure can guide and limit the sliding of the traction slide 3, and prevent the traction slide 3 from deviating during the sliding process.

[0033] The working principle and usage process of this utility model:

[0034] In this wire rope traction structure, the maximum sliding stroke of the traction slide 3 is limited by the sliding baffle mechanism 5, which is the maximum traction distance of the wire rope, i.e., the cutting length. Based on the above principle, the displacement of the sliding baffle mechanism 5 is read by the stroke reference mechanism 6, which facilitates precise adjustment of the position of the sliding baffle mechanism 5. There is no need to use a ruler to mark the position on the wire rope, which simplifies the operation and reduces the error. When the traction length is reached, the traction slide 3 will be unable to move further due to the obstruction of the sliding baffle mechanism 5, eliminating the need for manual judgment of the stop position and further reducing the error. The portal baffle 51 can slide along the guide rail 2 to change its position, thereby adjusting the maximum sliding stroke of the traction slide 3. After the adjustment is completed, the position of the portal baffle 51 can be fixed by the cooperation of the locking thread 54 and the locking guide plate 52. When the position of the portal baffle 51 is adjusted, it will drive the pointer 61 to move synchronously. The user can determine the current position of the portal baffle 51 by the value change of the scale line 63 corresponding to the pointer 61, which makes it easier for the user to adjust the position more accurately.

[0035] In addition, the drive motor 7 and the transmission screw 9 are connected by a friction drive 8. When the traction slide 3 is blocked by the sliding baffle mechanism 5 and cannot move, the friction drive 8 slips due to the friction force and no longer outputs torque. At this time, the transmission screw 9 stops rotating. This connection method can prevent the drive motor 7 from being blocked and damaged when the traction slide 3 is blocked.

[0036] Based on the structure and working principle of the friction drive 8, when the traction slide 3 moves without obstruction, the friction between the inner friction pad 82 and the outer friction sleeve 84 can play a transmission role, thereby transmitting torque and causing the transmission screw 9 to rotate. When the traction slide 3 is obstructed and cannot continue to move, the transmission screw 9 can no longer rotate. At this time, the operation of the drive motor 7 will drive the inner friction pad 82 and the outer friction sleeve 84 to rotate relative to each other, preventing the drive motor 7 from burning out and giving the operator enough time to shut off the drive motor 7.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
