Description

Technical Field

[0001] The utility model relates to the technical field of electric tugboats, in particular to a steering mechanism of an electric tugboat. Background Art

[0002] An electric tugboat refers to a support wheel driven by electricity. The electric tugboat can be installed on a trailer or other loading platform to drag and transport heavy objects to improve the transportation efficiency of heavy objects. At the same time, in order to make the electric tugboat more flexible when towing goods, a steering mechanism is usually installed on the tugboat so that the tugboat can drive the loading platform to adjust and change the direction.

[0003] However, when the steering mechanism of the existing electric tugboat is in use, it is usually meshed with a gear set consisting of two gears to realize the steering of the wheel, and one of the gears is usually fixed to the top of the tugboat by screws in order to increase the firmness of the connection with the wheel, which makes the gear more troublesome and time-consuming to disassemble and replace when it is needed; in addition, when the existing electric tugboat is driven to turn, since the electric-driven tugboat rotates at a faster speed, it will also turn at a faster speed, and it is impossible to remind and avoid the surrounding personnel during the turning process, which makes it easy for the tugboat to collide with the personnel after turning, and the safety factor during use is low. Utility Model Content

[0004] The purpose of the utility model is to provide a steering mechanism for an electric tugboat to solve the problems raised in the above background technology.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figures 1 to 4 As shown, the steering mechanism of the electric tugboat in this embodiment includes a support frame 1, a tugboat body 2 is installed on one side of the bottom end of the support frame 1 through a rotating shaft 9, a column 5 is fixedly connected to one side of the top end of the support frame 1, four card slots 10 are opened on the top of the column 5, a gear ring 3 is provided in the middle of the column 5, four card strips 4 are fixedly connected to the inner wall of the gear ring 3, a rotating rod 7 is provided on the top of the support frame 1, an external gear 6 is sleeved on the top of the rotating rod 7, a ring 11 is sleeved in the middle of the rotating rod 7, a plurality of thin ropes 12 are movably connected to the outer wall of the ring 11, a small ball 13 is fixedly connected to the bottom end of the thin rope 12, a bell 8 is provided on one side of the ring 11, and a rotating motor 15 is fixedly installed on the other side of the bottom end of the support frame 1.

[0024] Specifically, the support frame 1 is in an "F" shape, so that the driving motor that drives the rotating rod 7 to rotate can be separated from the tugboat body 2, reducing the interference of the driving motor on the rotation of the tugboat body 2, and making the tugboat body 2 more stable when turning. The column 5 is cylindrical, and the outer diameter is adapted to the inner diameter of the gear ring 3, so that the gear ring 3 can be smoothly sleeved on the column 5, and temporarily engaged and fixed with the card strip 4 and the card slot 10. The length of the card slot 10 is the same as that of the card strip 4, so that after the gear ring 3 is sleeved on the column 5, the top of the card strip 4 and the top of the card slot 10 are in an overlapping state, and the function of the gear ring 3 is to mesh with the external gear 6, thereby driving the column 5 rotates, so that the column 5 drives the support frame 1 to rotate, thereby realizing the steering of the tugboat body 2. The function of the rotating rod 7 is to connect the external gear 6 and the driving motor, so that the driving motor can drive the external gear 6 to rotate after being powered on. The function of the ring 11 is to connect the top of the thin rope 12 with the middle part of the rotating rod 7, so that when the rotating rod 7 rotates, the thin rope 12 can be thrown up with the rotation of the rotating rod 7, thereby driving the small ball 13 to be thrown up, so that the small ball 13 can collide with the bell cover 8 in turn, so that the bell cover 8 emits a metallic sound. The bottom end of the bell cover 8 is not closed, so that the sound emitted by the collision can be emitted from the bottom end of the bell cover 8, thereby realizing the sound reminder of the steering mechanism.

[0025] Furthermore, the clamping strip 4 is movably engaged with the clamping slot 10, and the gear ring 3 is movably sleeved and connected with the column 5 through the clamping strip 4. After the clamping strip 4 is successfully engaged with the clamping slot 10, the gear ring 3 will stay in the middle of the column 5, so that the gear ring 3 can be smoothly engaged with the external gear 6, thereby facilitating the disassembly, assembly and replacement of the gear ring 3.

[0026] Furthermore, the bottom end of the rotating rod 7 is engaged with the output end of the rotating motor 15, and the rotating rod 7 is rotationally connected to the support frame 1 through the rotating motor 15. After being energized, the rotating motor 15 can drive the rotating rod 7 to rotate at the top of the support frame 1, thereby realizing the driven rotation of the external gear 6.

[0027] Furthermore, the outer gear 6 is movably meshed with the gear ring 3 via the rotating rod 7. Driven by the rotating rod 7, the outer gear 6 can mesh with the gear ring 3 to rotate, thereby realizing the gear ring 3 driving the column 5 to rotate, so that the column 5 moves the support frame 1 and the tug body 2 at the bottom of the support frame 1 to turn.

[0028] Furthermore, the inner side of the bell jar 8 is movably connected with a vertical rod 14, the bottom end of which is fixedly connected to the support frame 1. The vertical rod 14 supports and limits the bell jar 8, so that the bell jar 8 can contact the thrown ball 13 in turn, thereby allowing the bell jar 8 to continuously emit sounds to provide voice reminders to people around.

[0029] Furthermore, the bell jar 8 is movably connected to the support frame 1 through the vertical rod 14, and the bell jar 8 is movably connected to the ring 11 through the support frame 1. After continuous collision with the ball 13, the bell jar 8 will swing left and right along the vertical rod 14 and continue to make sounds, thereby realizing voice reminders to people around.

[0030] Furthermore, the ball 13 is movably connected to the ring 11 through the thin rope 12, and the ball 13 is movably connected to the bell 8 through the rotating rod 7. After the rotating rod 7 drives the ring 11 to rotate, the ball 13 can be pulled and thrown up by the thin rope 12, so that the ball 13 can collide with the bell 8, thereby achieving the bell 8 to make a sound after being knocked.

[0031] The method of using this embodiment is as follows: when using the steering mechanism of the electric tugboat, the steering mechanism needs to be installed on the electric tugboat first. When the electric tugboat is turning, the driving motor will drive the rotating rod 7 to rotate, so that the rotating rod 7 drives the ring 11 to rotate, so that the thin rope 12 on the outer wall of the ring 11 drives the small ball 13 at the bottom to be thrown up, so that the small ball 13 collides with the bell cover 8 in sequence. At this time, the bell cover 8 will continue to emit a metal collision sound, and give a sound reminder to the people moving around, so that the people moving around can avoid the electric tugboat in time. At the same time, the outer gear 6 on the rotating rod 7 will drive the gear ring 3 to rotate, drive the column 5 to rotate, and drive the support frame 1 and the tugboat body 2 at the bottom of the support frame 1 to perform a steering action. When the gear ring 3 needs to be replaced, the gear ring 3 can be lifted up first, so that the clamping strip 4 on the gear ring 3 slides up along the clamping groove 10 at the top of the column 5 until the gear ring 3 is separated from the column 5, and the disassembly of the gear ring 3 is completed, and then the new gear ring 3 can be installed and fixed on the column 5.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
