Description

Technical Field

[0001] This utility model relates to the field of traction equipment technology, specifically to a track for a port traction machine that is easy to adjust. Background Technology

[0002] In port cargo transportation, tractors rely on tracks to achieve efficient operations, completing the loading, unloading, and transfer of goods. Their operational efficiency affects the port's throughput. However, existing port tractor tracks have shortcomings in practical applications. Most existing port tractor tracks are designed with fixed spacing, which lacks flexibility. Port cargo is diverse, and different types of tractors are used for different cargoes, with varying models and sizes, and different track spacing requirements. For example, the track spacing required for tractors transporting large containers differs significantly from that for tractors transporting small bulk cargo. Traditional fixed-spacing tracks cannot meet diverse needs. When faced with tractors of incompatible sizes, most require modification of the tractor or readjustment of the track. The former is time-consuming, labor-intensive, and increases costs, while the latter involves a large amount of engineering work and affects the normal operation of the port. In addition, fixed-spacing tracks are difficult to adjust flexibly to adapt to special cargo loading and unloading needs when dealing with different operating scenarios, which limits the improvement of port operation efficiency.

[0020] Please see Figure 1-4This utility model provides a technical solution: a port traction machine track that is easy to adjust, including a fixed base 1, a sliding frame 3 slidably connected to the outer wall of the fixed base 1, a track body 4 fixedly connected to the top outer wall of the sliding frame 3, a limit frame 2 symmetrically fixedly connected to the top outer wall of the fixed base 1, and a covering device 5 fixedly connected to the top outer wall of the limit frame 2. It also includes an adjustment device 6, the outer wall of which is fixedly connected to the outer wall of the fixed base 1; the adjustment device 6 includes a dual-output shaft motor 61, the output ends of which are symmetrically fixedly connected to adjustment screws 62, and a sliding block 63 threadedly connected to the outer wall of the adjustment screw 62. A connecting rod 64 is symmetrically rotatably connected to the wall. The end of the connecting rod 64 away from the sliding block 63 is fixedly connected to a connecting shaft 65. A dual-output shaft motor 61 is fixed on the top of the fixed base 1. After starting, its two output ends synchronously drive the symmetrical adjusting screw 62 to rotate. Since the adjusting screw 62 is threadedly connected to the sliding block 63, according to the principle of thread transmission, the sliding block 63 will move along the axial direction of the adjusting screw 62. The connecting rod 64, which is rotatably connected to the outer wall of the sliding block 63, converts the linear motion of the sliding block 63 into the rotation of the connecting shaft 65 when the sliding block 63 moves. The top of the connecting shaft 65 is connected to the bottom of the track body 4, thereby driving the track bodies 4 to move closer to each other to adjust the spacing.

[0021] The outer wall of the limiting frame 2 is slidably connected to the outer wall of the sliding frame 3. The outer wall of the bottom of the dual-output shaft motor 61 is fixedly connected to the outer wall of the top of the fixed seat 1. The adjusting screw 62 is rotatably connected to the inner wall of the limiting frame 2 away from the outer wall of the dual-output shaft motor 61. The inner wall of the top of the connecting shaft 65 is rotatably connected to the outer wall of the bottom of the track body 4.

[0022] A protective frame 11 is fixedly connected to the outer wall of the top of the fixed base 1. A connecting hole 12 is provided in the wall of the protective frame 11. A heat dissipation groove 13 is provided on the outer wall of the fixed base 1. An arc-shaped groove 14 is symmetrically provided on the inner wall of the fixed base 1. A water outlet groove 15 is provided on the outer wall of the bottom of the fixed base 1. A vent hole 16 is provided on the side wall of the fixed base 1. The heat dissipation groove 13 is connected to the vent hole 16. The arc-shaped groove 14 is connected to the water outlet groove 15. The side of the arc-shaped groove 14 away from the vent hole 16 is connected to the heat dissipation groove 13. The inner side wall of the protective frame 11 is fixedly connected to the outer wall of the dual-shaft motor 61. The inner wall of the protective frame 11 is connected to the connecting hole 12. The hole 12 is rotatably connected to the outer wall of the adjusting screw 62. The heat dissipation groove 13, the vent hole 16, the arc groove 14, and the water outlet groove 15 opened on the fixed base 1 together constitute a heat dissipation and drainage system. The heat dissipation groove 13 is connected to the vent hole 16 to accelerate air circulation and remove the heat generated by the dual-output shaft motor 61 components, preventing the equipment from overheating and being damaged. The arc groove 14 is connected to the water outlet groove 15. When the water flows through the arc groove 14 to the bottom of the arc surface, it can be discharged from the water outlet groove 15 at the bottom, thereby timely draining the water accumulated under the track body 4 and preventing the track body 4 and the dual-output shaft motor 61 from being corroded by water accumulation.

[0023] The covering device 5 includes a covering plate 51. A lifting pad 52 is fixedly connected to the outer wall of the bottom of the covering plate 51. A limiting groove 53 is opened in the wall of the covering plate 51. The outer wall of the bottom of the covering plate 51 is fixedly connected to the outer wall of the top of the protective frame 11. The outer wall of the bottom of the lifting pad 52 is fixedly connected to the outer wall of the top of the limiting frame 2. The inner wall of the covering plate 51 is slidably connected to the outer wall of the connecting shaft 65 through the limiting groove 53. The covering plate 51 is fixed to the top of the limiting frame 2 through the lifting pad 52 at the bottom. The limiting groove 53 of its inner wall is slidably connected to the outer wall of the connecting shaft 65. When the track body 4 is adjusted in terms of spacing, the connecting shaft 65 slides in the limiting groove 53. The covering plate 51 can always cover the adjusting device 6, which plays a role in dust prevention and rain protection. Together with the grooved protection on the fixed seat 1, the adjusting device 6 is not easily corroded by the external environment.

[0024] In use, the easily adjustable port traction machine rail is based on the fixed base 1. The adjustment device 6 and the covering device 5 work together to achieve rail adjustment and protection, meeting the requirements of the port operating environment. The fixed base 1, as the support for the rail, is installed on the port ground. The symmetrically fixed limiting frame 2 on its top not only guides the sliding of the rail body 4 but also limits its movement, ensuring the rail remains stable during sliding. The protective frame 11 on top of the fixed base 1, on the one hand, provides protection for the dual-output shaft motor 61, preventing damage to the motor in the dusty, humid, and other harsh environments of the port; on the other hand, the connecting hole 12 in the wall of the protective frame 11 connects with the adjustment... The adjusting screw 62 is engaged to allow it to rotate smoothly. The heat dissipation groove 13, the vent hole 16, the arc groove 14, and the water outlet groove 15 on the fixed base 1 together constitute a heat dissipation and drainage system. The heat dissipation groove 13 is connected to the vent hole 16 to accelerate air circulation and remove the heat generated by the dual-output shaft motor 61 components, preventing the equipment from overheating and being damaged. The arc groove 14 is connected to the water outlet groove 15. When the water flows through the arc groove 14 to the bottom of the arc surface, it can be discharged from the water outlet groove 15 at the bottom, thereby timely draining the water accumulated under the track body 4, preventing the track body 4 and the dual-output shaft motor 61 from being corroded by water accumulation, and thus extending their service life.

[0025] The adjusting device 6 is a component for adjusting the track spacing. The dual-output shaft motor 61 is fixed on the top of the fixed base 1. After starting, its two output ends synchronously drive the symmetrical adjusting screws 62 to rotate. Since the adjusting screws 62 are threadedly connected to the sliding block 63, according to the principle of thread transmission, the sliding block 63 will move along the axial direction of the adjusting screws 62. The connecting rod 64 rotatably connected to the outer wall of the sliding block 63 converts its linear motion into the rotation of the connecting shaft 65 when the sliding block 63 moves. The top of the connecting shaft 65 is connected to the bottom of the track body 4, thereby driving the track bodies 4 to move closer to each other to adjust the spacing. In this way, the spacing of the track bodies 4 can be flexibly adjusted according to the operating requirements of the port tractor, which is convenient for the tractor to load and unload goods.

[0026] The covering device 5 is installed on the top of the limiting frame 2 and the protective frame 11. The covering plate 51 is fixed to the top of the limiting frame 2 by the lifting pad 52 at the bottom. The limiting groove 53 on its inner wall is slidably connected to the outer wall of the connecting shaft 65. When the track body 4 is adjusted in terms of spacing, the connecting shaft 65 slides in the limiting groove 53. The covering plate 51 can always cover the adjusting device 6, which can play a role in dust prevention and rain protection. Together with the slotted protection on the fixed seat 1, the adjusting device 6 is not easily corroded by the external environment, thereby improving the reliability and durability of the track system.
