Abstract
Description
Technical Field
[0001] This utility model belongs to the field of track traction technology, and in particular relates to a skateboard track traction system. Background Technology
[0002] The skateboard tracked traction is a special traction device with a tracked walking system as its core and a low center of gravity skateboard-type load-bearing platform. Its core feature is that it combines the all-terrain passability of tracks with the flexible maneuverability of skateboard structure. It is designed for traction operations in complex terrain, heavy load transportation or special scenario movement, and is different from ordinary wheeled tractors and traditional heavy tracked vehicles.
[0003] Traditional spherical towing bolts on skateboard track towing systems use a fixed-height design. However, different types of towed equipment, such as small aircraft, engineering machinery, and cargo trailers, have significantly different towing interface heights. Since the fixed-length spherical towing bolts can only be used with towing interfaces of a single height, the equipment often cannot effectively dock when faced with multiple types of towed objects. In some application scenarios, towing operations are even completely impossible, severely limiting the equipment's versatility and adaptability.
[0004] To solve the aforementioned height adaptation problem, some existing skateboard tracked traction devices have adopted a threaded adjustable connecting column structure. The specific design is as follows: the connecting column consists of an inner tube and an outer tube nested together. The outer wall of the inner tube is machined with external threads, and the inner wall of the outer tube is machined with a corresponding matching internal thread. A locking nut is installed at the top of the outer tube. The length adjustment process is as follows: first, loosen the locking nut at the top of the outer tube, and then rotate the inner tube or the outer tube to realize the extension and retraction movement of the inner tube relative to the outer tube through threaded engagement. After the length is adjusted to the target adaptation value, tighten the locking nut to fix the relative position of the inner and outer tubes, thus completing the calibration of the height of the spherical traction bolt.
[0005] However, this threaded adjustment scheme still has obvious technical limitations: due to the inherent characteristics of threaded meshing transmission, the length adjustment of the connecting column needs to be achieved step by step through rotation operation. The adjustment process is cumbersome and time-consuming, and it cannot quickly complete the height adaptation. This results in a significant reduction in the operating efficiency of the equipment in frequent switching of the towed equipment or emergency operation scenarios, making it difficult to meet the actual use requirements of efficient traction. In view of this, we propose a skateboard track traction. Utility Model Content
[0006] The purpose of this invention is to provide a skateboard-type tracked traction system to solve the problems mentioned in the background art.
[0007] In view of this, the present invention provides a skateboard-type tracked traction system, including a track body, and further comprising: A connecting post is fixedly connected to the top surface of the track body. A first sliding groove is provided on the top surface of the connecting post. A support rod is slidably connected in the first sliding groove. A spherical traction bolt is fixedly connected to the top end of the support rod. A through groove is formed on the inner wall of the first sliding groove and communicates with the outside. A sliding rod is slidably connected in the through groove. Two first limiting grooves and two second limiting grooves are formed on the periphery of the sliding rod. A first clamping block is slidably connected in the two first limiting grooves and the two first clamping blocks are located in the inner cavity of the first sliding groove and in contact with the inner wall of the first sliding groove. A second clamping block is slidably connected in each of the two second limiting grooves and the two second clamping blocks are located on the outside and in contact with the periphery of the connecting column. An adjustment assembly, located inside the slide bar, is used to move two first clamping blocks and two second clamping blocks.
[0008] This technical solution ensures that users can quickly adjust the height of the spherical traction bolt, thereby improving the efficiency of the spherical traction bolt height adjustment.
[0009] In the above technical solution, the adjustment component further includes: Two first rotating grooves are formed inside the slide rod and are respectively connected to two first limiting grooves and two second limiting grooves. Two bidirectional threaded rods are rotatably connected in each of the two first rotating grooves, and the two ends of the two bidirectional threaded rods extend into the two first limiting grooves and the two second limiting grooves respectively and are threadedly connected to the two first clamping blocks and the two second clamping blocks respectively. The second rotating groove is opened inside the slide rod and is connected to the two first limiting grooves. A connecting rod is rotatably connected inside the second rotating groove, and the two ends of the connecting rod extend into the two first limiting grooves and are fixedly connected to one end of the two bidirectional threaded rods respectively. The third rotating groove is formed on one side of the slide rod and is connected to one of the second limiting grooves. A rotating rod is rotatably connected in the third rotating groove, and one end of the rotating rod extends into one of the second limiting grooves and is fixedly connected to the other end of one of the bidirectional threaded rods.
[0010] In this technical solution, it is ensured that the user can simultaneously move the two first clamping blocks and the two second clamping blocks.
[0011] In the above technical solution, the threads on both ends of the bidirectional threaded rod have opposite directions of rotation and the same thread pitch. The two ends of the two bidirectional threaded rods are respectively rotatably connected to the two first limiting grooves and the two second limiting grooves.
[0012] In this technical solution, because the threads at both ends of the bidirectional threaded rod have opposite directions of rotation and the same thread pitch, when the two bidirectional threaded rods rotate, the two first clamping blocks and the two second clamping blocks will be acted upon by the opposite threads at both ends of the two bidirectional threaded rods, and will move simultaneously along the two first limiting grooves and the two second limiting grooves, respectively, so that the corresponding first clamping blocks and second clamping blocks move closer to each other or further away from each other, and ensure that when the two bidirectional threaded rods rotate, the two ends of the two bidirectional threaded rods can rotate normally within the two first limiting grooves and the two second limiting grooves, respectively.
[0013] In the above technical solution, further, both ends of the connecting rod are rotatably connected to two first limiting grooves respectively, one end of the rotating rod is rotatably connected to one of the second limiting grooves, and anti-slip texture is provided on the periphery of the rotating rod.
[0014] In this technical solution, it is ensured that when the connecting rod rotates, both ends of the connecting rod can rotate normally in the two first limiting grooves respectively, and that when the rotating rod rotates, one end of the rotating rod can rotate normally in one of the second limiting grooves. At the same time, because the rotating rod is provided with anti-slip texture on its periphery, when the user rotates the rotating rod by hand, it will be affected by the anti-slip texture on the periphery of the rotating rod, reducing the problem of hand slippage.
[0015] Furthermore, the above technical solution also includes: Two second sliding grooves are formed on the inner wall of the third rotating groove. Each of the two second sliding grooves is slidably connected with a clamping plate, and the two clamping plates are located on the upper and lower sides of the rotating rod. Each of the two clamping plates is threaded with a one-way threaded rod. The gear groove is formed inside the slide rod and communicates with two second slide grooves. Two first bevel gears and two second bevel gears are rotatably connected in the gear groove and mesh with each other. One end of each of the two first bevel gears extends into the two second slide grooves and is fixedly connected to two one-way threaded rods respectively. A rotating block is fixedly connected to the second bevel gear, and one end of the rotating block penetrates the inner wall of the gear groove and extends to the outside.
[0016] In this technical solution, it is ensured that the rotating rod will not be affected by external factors and will not rotate.
[0017] In the above technical solution, further, the threads on the two one-way threaded rods have the same direction of rotation and the same thread pitch, one end of each of the two first bevel gears is rotatably connected to the two second slide grooves respectively, the one-way threaded rod is located in the second slide groove and is rotatably connected to the second slide groove, and the rotating block is rotatably connected to the slide rod.
[0018] In this technical solution, because the threads on the two one-way threaded rods have the same direction of rotation and the same thread pitch, when the two one-way threaded rods rotate in opposite directions, the two clamping plates will be acted upon by the threads of the two one-way threaded rods respectively, and will move closer to each other or further away from each other along the two second sliding grooves. This ensures that when the two first bevel gears rotate, one end of each of the two first bevel gears can rotate normally within the two second sliding grooves, and also ensures that when the one-way threaded rods rotate, they can rotate normally within the second sliding grooves. At the same time, it ensures that when the rotating block rotates, the rotating block can rotate normally within the sliding rod.
[0019] The beneficial effects of this utility model are: 1. This skateboard-type tracked traction system allows users to adjust the height of the spherical traction bolt through a first sliding groove, support rod, and through groove. The through groove, sliding rod, first limiting groove, second limiting groove, first clamping block, second clamping block, first rotating groove, bidirectional threaded rod, second rotating groove, connecting rod, third rotating groove, and rotating rod enable users to quickly fix the spherical traction bolt when its height is adjusted to the appropriate position. This structural design achieves rapid height adjustment of the spherical traction bolt, reducing the time consumed in the adjustment process and allowing the entire device to quickly adapt to the desired height, thus meeting the practical requirements of efficient traction.
[0020] 2. This skateboard-type track traction system, through the provision of a second sliding groove and clamping plates, allows two clamping plates to move along the two second sliding grooves respectively. Through the provision of a one-way threaded rod, gear groove, first bevel gear, second bevel gear, and rotating block, the user can drive the two clamping plates closer to each other or further apart. The design of the above structure achieves locking of the rotating rod, preventing the rotating rod from rotating during long-term use, thereby improving the stability of the overall device.

[0028] Example 1: Please refer to Figure 1 - Figure 6 As shown, this embodiment provides a skateboard-type tracked traction system, including a track body 1, and further comprising: Connecting column 2 is fixedly connected to the top surface of track body 1. A first groove 3 is provided on the top surface of connecting column 2. A support rod 4 is slidably connected in the first groove 3. A spherical traction bolt 5 is fixedly connected to the top of the support rod 4. A through groove 6 is formed on the inner wall of the first sliding groove 3 and is connected to the outside. A sliding rod 7 is slidably connected in the through groove 6. Two first limiting grooves 8 and two second limiting grooves 9 are formed on the periphery of the sliding rod 7. A first clamping block 10 is slidably connected in the two first limiting grooves 8, and the two first clamping blocks 10 are located in the inner cavity of the first sliding groove 3 and are in contact with the inner wall of the first sliding groove 3. A second clamping block 11 is slidably connected in each of the two second limiting grooves 9, and the two second clamping blocks 11 are located on the outside and are in contact with the periphery of the connecting column 2. An adjustment assembly is located inside the slide bar 7 and is used to move the two first clamping blocks 10 and the two second clamping blocks 11.
[0029] In operation, the user slides the spherical traction bolt 5 by hand, causing the support rod 4 to move upward along the first slide groove 3. When the height of the spherical traction bolt 5 is adjusted to the appropriate position, the user slides the slide rod 7 by hand, causing the slide rod 7 to move upward along the through groove 6, so that the slide rod 7 causes the two first clamping blocks 10 to come into contact with the bottom end of the support rod 4. Then, the user uses the adjustment component to move the two first clamping blocks 10 and the two second clamping blocks 11 along the two first limiting grooves 8 and the two second limiting grooves 9 respectively, so that the corresponding first clamping blocks 10 and second clamping blocks 11 move closer to each other or further away from each other. When the two first clamping blocks 10 and the two second clamping blocks 11 move and the corresponding first clamping blocks 10 and second clamping blocks 11 move closer to each other, the two first clamping blocks 10 will be tightly pressed against the inner wall of the first slide groove 3, and the two second clamping blocks 11 will be tightly clamped on the periphery of the connecting column 2, fixing the slide rod 7 in the through groove 6 and preventing it from sliding. This ensures that the user can quickly adjust the height of the spherical traction bolt 5, thereby improving the efficiency of the height adjustment of the spherical traction bolt 5.
[0030] Example 2: This example provides a skateboard track traction system. In addition to the technical solutions described in the above examples, it also has the following technical features: the adjustment components include: Two first rotating grooves 12 are formed in the slide rod 7 and are respectively connected to two first limiting grooves 8 and two second limiting grooves 9. Two bidirectional threaded rods 13 are rotatably connected in each of the two first rotating grooves 12, and the two ends of the two bidirectional threaded rods 13 extend into the two first limiting grooves 8 and the two second limiting grooves 9 respectively and are threadedly connected to the two first clamping blocks 10 and the two second clamping blocks 11 respectively. The second rotating groove 14 is opened in the slide rod 7 and is connected to the two first limiting grooves 8. A connecting rod 15 is rotatably connected in the second rotating groove 14, and the two ends of the connecting rod 15 extend into the two first limiting grooves 8 and are fixedly connected to one end of the two bidirectional threaded rods 13 respectively. The third rotating groove 16 is opened on one side of the slide rod 7 and is connected to one of the second limiting grooves 9. A rotating rod 17 is rotatably connected in the third rotating groove 16, and one end of the rotating rod 17 extends into one of the second limiting grooves 9 and is fixedly connected to the other end of one of the bidirectional threaded rods 13.
[0031] In use, the user manually rotates the rotating rod 17, causing one end of the rotating rod 17 to drive one of the bidirectional threaded rods 13 to rotate within one of the first rotating grooves 12. This causes one of the bidirectional threaded rods 13 to drive the other bidirectional threaded rod 13 to rotate via the connecting rod 15. When the two bidirectional threaded rods 13 rotate, the two first clamping blocks 10 and the two second clamping blocks 11 are respectively acted upon by the opposite threads at both ends of the two bidirectional threaded rods 13, and move along the two first limiting grooves 8 and the two second limiting grooves 9 respectively. This allows the corresponding first clamping blocks 10 and second clamping blocks 11 to move closer to or further away from each other, ensuring that the user can simultaneously drive the two first clamping blocks 10 and the two second clamping blocks 11 to move.
[0032] Example 3: This example provides a skateboard track traction system. In addition to the technical solutions of the above examples, it also has the following technical features: the threads on both ends of the bidirectional threaded rod 13 have opposite directions and the same thread pitch. The two ends of the two bidirectional threaded rods 13 are rotatably connected to the two first limiting grooves 8 and the two second limiting grooves 9, respectively.
[0033] Because the threads at both ends of the bidirectional threaded rod 13 have opposite directions of rotation and the same thread pitch, when the two bidirectional threaded rods 13 rotate, the two first clamping blocks 10 and the two second clamping blocks 11 will be acted upon by the opposite threads at both ends of the two bidirectional threaded rods 13, and will move simultaneously along the two first limiting grooves 8 and the two second limiting grooves 9, respectively. This allows the corresponding first clamping blocks 10 and second clamping blocks 11 to move closer to or further away from each other, and ensures that when the two bidirectional threaded rods 13 rotate, both ends of the two bidirectional threaded rods 13 can rotate normally within the two first limiting grooves 8 and the two second limiting grooves 9, respectively.
[0034] Example 4: This example provides a skateboard track traction system. In addition to the technical solutions of the above examples, it also has the following technical features: the two ends of the connecting rod 15 are rotatably connected to the two first limiting grooves 8 respectively, one end of the rotating rod 17 is rotatably connected to one of the second limiting grooves 9, and anti-slip textures are provided on the periphery of the rotating rod 17.
[0035] Specifically, it is ensured that when the connecting rod 15 rotates, both ends of the connecting rod 15 can rotate normally within the two first limiting grooves 8 respectively, and that when the rotating rod 17 rotates, one end of the rotating rod 17 can rotate normally within one of the second limiting grooves 9. At the same time, because the rotating rod 17 has anti-slip texture on its periphery, when the user rotates the rotating rod 17 by hand, it will be affected by the anti-slip texture on the periphery of the rotating rod 17, reducing the problem of hand slippage.
[0036] Example 5: This example provides a skateboard tracked traction system, which, in addition to the technical solutions of the above examples, also has the following technical features and includes: Two second slide grooves 18 are formed on the inner wall of the third rotating groove 16. Each of the two second slide grooves 18 is slidably connected with a clamping plate 19, and the two clamping plates 19 are located on the upper and lower sides of the rotating rod 17. Each of the two clamping plates 19 is threadedly connected with a one-way threaded rod 20. Gear groove 21 is formed inside slide rod 7 and communicates with two second slide grooves 18. Two first bevel gears 22 and second bevel gears 23 are rotatably connected inside gear groove 21 and mesh with each other. One end of each of the two first bevel gears 22 extends into the two second slide grooves 18 and is fixedly connected to two one-way threaded rods 20 respectively. A rotating block 24 is fixedly connected to the second bevel gear 23 and one end of the rotating block 24 penetrates the inner wall of gear groove 21 and extends to the outside.
[0037] In use, the user manually rotates the rotating block 24, causing the rotating block 24 to drive the second bevel gear 23 to rotate within the gear groove 21. This causes the second bevel gear 23 to drive the two first bevel gears 22 to rotate in opposite directions within the gear groove 21. When the two first bevel gears 22 rotate, they will drive the two one-way threaded rods 20 to rotate in opposite directions. When the two one-way threaded rods 20 rotate in opposite directions, the two clamping plates 19 will be acted upon by the threads of the two one-way threaded rods 20, moving closer or further apart along the two second sliding grooves 18. This allows the two clamping plates 19 to be clamped and fixed by the rotating rod 17, ensuring that the rotating rod 17 is not affected by external factors and does not rotate.
[0038] Example 6: This example provides a skateboard track traction system. In addition to the technical solutions of the above examples, it also has the following technical features: the threads on the two one-way threaded rods 20 have the same direction of rotation and the same thread pitch; one end of each of the two first bevel gears 22 is rotatably connected to the two second slide grooves 18; the one-way threaded rod 20 is located in the second slide groove 18 and is rotatably connected to the second slide groove 18; and the rotating block 24 is rotatably connected to the slide rod 7.
[0039] Because the threads on the two one-way threaded rods 20 have the same direction of rotation and the same pitch, when the two one-way threaded rods 20 rotate in opposite directions, the two clamping plates 19 will be acted upon by the threads of the two one-way threaded rods 20 respectively, moving closer or further away from each other along the two second sliding grooves 18. This ensures that when the two first bevel gears 22 rotate, one end of each first bevel gear 22 can rotate normally within the two second sliding grooves 18, and also ensures that when the one-way threaded rod 20 rotates, it can rotate normally within the second sliding groove 18. At the same time, it ensures that when the rotating block 24 rotates, it can rotate normally within the sliding rod 7.
[0040] Working principle: In use, the user slides the ball-shaped traction bolt 5 by hand, causing the ball-shaped traction bolt 5 to move the support rod 4 upward along the first sliding groove 3. When the height of the ball-shaped traction bolt 5 is adjusted to a suitable position, the user slides the sliding rod 7 by hand, causing the sliding rod 7 to move upward along the through groove 6, so that the sliding rod 7 causes the two first clamping blocks 10 to contact the bottom end of the support rod 4. Then, the user rotates the rotating rod 17 by hand, causing one end of the rotating rod 17 to drive one of the bidirectional threaded rods 13 to rotate in one of the first rotating grooves 12, so that one of the bidirectional threaded rods 13 drives the other bidirectional threaded rod 13 to rotate through the connecting rod 15. When the two bidirectional threaded rods 13 rotate, the two first clamping blocks 10 and the two second clamping blocks 11... The two bidirectional threaded rods 13 are respectively acted upon by the opposite threads at both ends, and move along the two first limiting grooves 8 and the two second limiting grooves 9 respectively, so that the corresponding first clamping blocks 10 and second clamping blocks 11 move closer to each other or further away from each other. When the two first clamping blocks 10 and the two second clamping blocks 11 move and the corresponding first clamping blocks 10 and second clamping blocks 11 move closer to each other, the two first clamping blocks 10 will be tightly pressed against the inner wall of the first sliding groove 3, and the two second clamping blocks 11 will be tightly clamped on the periphery of the connecting column 2, fixing the sliding rod 7 in the through groove 6 and preventing it from sliding. This ensures that the user can quickly adjust the height of the ball traction bolt 5, thereby improving the efficiency of the height adjustment of the ball traction bolt 5. In use, the user manually rotates the rotating block 24, causing the rotating block 24 to drive the second bevel gear 23 to rotate within the gear groove 21. This causes the second bevel gear 23 to drive the two first bevel gears 22 to rotate in opposite directions within the gear groove 21. When the two first bevel gears 22 rotate, they will drive the two one-way threaded rods 20 to rotate in opposite directions. When the two one-way threaded rods 20 rotate in opposite directions, the two clamping plates 19 will be acted upon by the threads of the two one-way threaded rods 20, moving closer or further apart along the two second sliding grooves 18. This allows the two clamping plates 19 to be clamped and fixed by the rotating rod 17, ensuring that the rotating rod 17 is not affected by external factors and does not rotate.
[0041] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
