Description

Technical Field

[0001] The utility model relates to the technical field of electric tugboats, in particular to an electric tugboat with high stability. Background Art

[0002] The electric tugboat is a device composed of a drive motor and a reducer. It has the characteristics of smooth operation, low noise and long service life. In the field of warehousing and logistics, the electric tugboat can use electric trailers with high carrying capacity, high speed, environmental protection and economy to improve logistics efficiency and quality.

[0003] However, the existing electric tugboats integrate a drive motor and a reducer, so that the wheel part of the electric tugboat is not located in the middle of the tugboat shell. The drive motor and the reducer are heavy, so that the electric tugboat as a whole is easy to tilt toward the side where the drive motor or the reducer is located after installation, which makes the wheels of the electric tugboat prone to side slipping, which is not conducive to maintaining a good stability of the electric tugboat. In addition, after the existing electric tugboat is docked and installed with the trailer, the top shell will be in close contact with the trailer and bear the pressure of the heavy objects on the trailer, so that when the electric tugboat drives the trailer to turn, the shell will frequently wear against the trailer, resulting in the shell of the electric tugboat being more likely to shorten its service life due to wear. Utility Model Content

[0004] The purpose of the utility model is to provide an electric tugboat with high stability to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric tugboat with high stability, comprising a shell, a support member butt joint pipe is fixedly connected to one side of the top of the shell, a fixing plate is provided at the bottom of the support member butt joint pipe, a disc is provided at the top of the shell, a plurality of balls are movably embedded at the top of the disc, wipers are fixedly connected to both side walls of the disc, a driving motor is fixedly installed inside the shell, an electric wheel is sleeved on the output end of the driving motor, a groove is provided at the bottom end of the shell, a bracket is provided inside the groove, an auxiliary wheel is movably connected to the bottom end of the bracket, and a damping spring is provided at the top of the bracket.

[0011] Preferably, the bottom end of the vibration-damping spring is fixedly connected to the top end of the bracket, and the bracket is movably connected to the groove via the vibration-damping spring.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The electric tug with high stability can support the side of the electric tug close to the driving motor by the auxiliary wheels, the bracket, the groove and the shock-absorbing spring, so that the side where the wheel of the electric tug is located and the other side where the driving motor is located can maintain a balanced state, thereby reducing the probability of the electric tug as a whole tilting toward the side of the driving motor and the probability of the wheels of the electric tug side slipping, which is conducive to the electric tug maintaining its own stability.

[0014] 2. The electric tug with high stability uses a fixing plate, a disc, a ball and a wiper to prevent the top of the electric tug shell from directly contacting the bottom of the trailer, so that the friction between the electric tug shell and the bottom of the trailer changes from sliding friction to rolling friction, thereby reducing the degree of wear on the top of the electric tug shell, which is beneficial to extending the service life of the electric tug.

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 electric tug with high stability in this embodiment includes a shell 2, one side of the top of the shell 2 is fixedly connected to a support member butt pipe 1, the bottom of the support member butt pipe 1 is provided with a fixing plate 4, the top of the shell 2 is provided with a disc 5, the top of the disc 5 is movably embedded with a plurality of balls 6, both side walls of the disc 5 are fixedly connected with wipers 7, a driving motor 12 is fixedly installed inside the shell 2, an electric wheel 9 is sleeved on the output end of the driving motor 12, a groove 11 is provided at the bottom end of the shell 2, a bracket 10 is provided inside the groove 11, an auxiliary wheel 8 is movably connected to the bottom end of the bracket 10, and a damping spring 14 is provided on the top of the bracket 10.

[0024] Specifically, the role of the shell 2 is to protect the wheel body of the electric tugboat and the motor driving the wheel to rotate, and to increase the anti-collision ability of the wheel and the driving motor 12. The role of the supporting member docking pipe 1 is to enable the electric tugboat to be installed and docked with the bottom end of the trailer. The material of the fixing plate 4 is metal material, and its role is to make friction contact with the wiper 7. After the electric tugboat is installed and fixed to the bottom end of the trailer, the disc 5 will be in contact with the bottom surface of the trailer, and when the electric tugboat turns, the ball 6 on the disc 5 will rotate in contact with the bottom surface of the trailer. At the same time, the rotating rod 16 at the bottom end of the disc 5 will also rotate along the top of the shell 2 through the rotating rod 16 under the action of the torque force generated during the turning, so that the top of the shell 2 is not in direct contact with the bottom surface of the bottom end of the trailer, thereby reducing the wear on the top of the shell 2, and the ball 6 It is a solid spherical structure and can rotate flexibly. The wiper 7 is made of rubber and can rub against the end of the fixed plate 4 as the disc 5 rotates, so that the surface of the wiper 7 is worn to reflect the wear generated when the disc 5 rotates, so that the user can judge the wear degree of the disc 5 according to the wear degree of the wiper 7, so that the user can replace the seriously worn disc 5 in time. The function of the groove 11 is to enable the bracket 10 to slide up and down on the bottom of the inner side of the shell 2, so as to achieve limited support for the auxiliary wheel 8. The function of the shock-absorbing spring 14 is to enable the auxiliary wheel 8 to always roll in contact with the ground, so that the gravity of the electric tug close to the driving motor 12 can always act on the ground through the auxiliary wheel 8, so as to maintain the balance of the electric tug and increase the stability of the electric tug.

[0025] Furthermore, a ring 3 is provided on the bottom end of the support member butt joint tube 1, and a fixing plate 4 is fixedly connected to the ring 3. The fixing plate 4 is fixedly connected to the support member butt joint tube 1 through the ring 3. The function of the ring 3 is to enable the fixing plate 4 to be fixed to the bottom end of the support member butt joint tube 1, so that the fixing plate 4 can smoothly contact and rub with the wiper 7 on the disc 5.

[0026] Furthermore, the wiper 7 is movably connected to the fixed plate 4 via the disc 5, and the wiper 7 can contact and rub with the fixed plate 4 as the disc 5 rotates, so that the degree of wear of the disc 5 can be reflected by the degree of wear of the wiper 7, which is convenient for the user to replace the severely worn disc 5 in time.

[0027] Furthermore, a rotating rod 16 is fixedly connected to the bottom end of the disc 5, and a rotating spring 15 is provided on the outer movable sleeve of the rotating rod 16. The function of the rotating spring 15 is to enable the disc 5 to return to its original position after rotation, so that the wiper 7 on the disc 5 can repeatedly contact and rub with the fixed plate 4.

[0028] Furthermore, the return spring 15 is movably connected to the housing 2, and the disc 5 is movably connected to the housing 2 via the return spring 15 and the rotating rod 16. At the same time, the return spring 15 can also assist the disc 5 to return to its original position, so that the rotation of the disc 5 is within a controllable range, thereby increasing the stability of the disc 5 during rotation.

[0029] Furthermore, a cavity 13 is provided at the top of the groove 11, and the top of the shock-absorbing spring 14 is fixedly connected to the top of the inner side of the cavity 13. The cavity 13 is communicated with the interior of the groove 11, so that the shock-absorbing spring 14 has sufficient space to deform, thereby facilitating the shock-absorbing spring 14 to support the bracket 10.

[0030] Furthermore, the bottom end of the damping spring 14 is fixedly connected to the top end of the bracket 10, and the bracket 10 is movably connected to the groove 11 through the damping spring 14. At the same time, the damping spring 14 can also reduce the vibration generated when the auxiliary wheel 8 contacts the ground, thereby reducing the interference with the rotation of the wheel of the electric tugboat.

[0031] The method of using this embodiment is as follows: when using the electric tug with high stability, it is necessary to first dock the support member docking tube 1 with the bottom end of the trailer so that the tug is installed at the bottom end of the trailer. At this time, the disc 5 at the top of the shell 2 will contact the bottom surface of the bottom end of the trailer. Then, the tug is powered on so that the driving motor 12 starts to drive the electric wheel 9 of the electric tug to start rotating. At the same time, the auxiliary wheel 8 will also roll against the ground under the action of the damping spring 14 and the bracket 10, so that when the electric wheel 9 rotates, the auxiliary wheel 8 can support the other side of the electric tug so that the electric wheel 9 rotates. Keep stable, at the same time, the ball 6 on the top of the disc 5 will rotate in contact with the bottom surface of the bottom end of the trailer. When the disc 5 is driven to rotate by the bottom end of the trailer, the wipers 7 on the two side walls of the disc 5 will contact and rub with the fixed plate 4 on the ring 3, so that the surface of the wiper 7 is worn. Since the disc 5 is between the shell 2 of the electric tugboat and the trailer, the shell 2 is not easy to be worn by the trailer for a long time, so that the top of the shell 2 of the electric tugboat is better protected. After using the electric tugboat for a long time, the wear degree of the disc 5 can be judged according to the wear degree of the wiper 7, so as to replace a new disc 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.
