Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0027] Please see Figure 1-6 This utility model provides a technical solution:

[0028] A convenient road curbstone lifting and relocation device includes a handle 1 and a lever assembly 2. The lever assembly 2 is fixedly connected to one side of the handle 1, and a support assembly 3 is fixedly connected to one side of the lever assembly 2. A sway-damping assembly 4 is installed inside the support assembly 3. The lever assembly 2 includes an inner bore lever 21, with a polygonal groove 22 formed inside the inner bore lever 21. A spring 23 is fixedly connected to one side of the polygonal groove 22 on the inner bore lever 21. A friction slide plate 24 is fixedly connected to one side of the spring 23. An internal slide rod 25 is fixedly connected to one side of the friction slide plate 24. A push handle 26 is fixedly connected to one side of the internal slide rod 25. A limit switch is fixedly connected to the outer side of the friction slide plate 24. The track 27 and support assembly 3 include a connecting support plate 31, an arc-shaped ball hole 32 is opened on the inner side of the connecting support plate 31, and a steel ball 33 is installed inside the arc-shaped ball hole 32. The anti-sway assembly 4 includes an inner hole rotating ball 41, a straight column 42 is fixedly connected to the inner side of the inner hole rotating ball 41, a folding plate 43 is fixedly connected to the top of the straight column 42, a level 44 is fixedly connected to the inner side of the folding plate 43, a steel wire rope 45 is installed at the bottom of the straight column 42, and a clamping claw 46 is installed at the bottom of the steel wire rope 45. One side of the inner hole lever 21 is fixedly connected to one side of the connecting support plate 31, the inner hole rotating ball 41 is installed inside the arc-shaped ball hole 32, and one side of the friction slide plate 24 is in contact with the outer side of the inner hole rotating ball 41.

[0029] As a further implementation of this solution, the left end of the polyhedral groove 22 is rectangular, and the right end of the polyhedral groove 22 is cylindrical. The left side of the push handle 26 is attached to the right side of the inner hole lever 21. The built-in slide rod 25 is installed inside the polyhedral groove 22, and the spring 23 is installed inside the polyhedral groove 22 at the left end. The left-view shape of the friction slide plate 24 is rectangular. The friction slide plate 24 slides inside the polyhedral groove 22 of the inner hole lever 21 through the limiting rail 27. When the push handle 26 is pushed, the built-in slide rod 25 drives the friction slide plate 24 to move, so that the friction slide plate 24 contacts the outside of the inner hole rotating ball 41. Under the action of the friction force between the friction slide plate 24 and the inner hole rotating ball 41, the rotation speed of the inner hole rotating ball 41 can be reduced.

[0030] As a further implementation of this solution, the limiting rail 27 is fixed to the front and rear ends of the friction slide plate 24. An arc-shaped groove is provided on the left side of the friction slide plate 24, and a rubber ball is fixedly connected to the left end of the friction slide plate 24 to increase the friction force between the friction slide plate 24 and the inner hole rotating ball 41 and the contact area between the friction slide plate 24 and the inner hole rotating ball 41.

[0031] As a further implementation of this solution, the arc-shaped ball hole 32 is partially spherical, and the connecting support plate 31 has a ball groove on the inner side near the arc-shaped ball hole 32. The outer side of the steel ball 33 fits against the outer side of the inner hole rotating ball 41, which can reduce the friction when the inner hole rotating ball 41 rotates, reduce the wear of the connecting support plate 31, and improve the service life of the connecting support plate 31.

[0032] As a further implementation of this solution, a rectangular groove is provided on the inner side of the connecting support plate 31 near the friction slide plate 24. The friction slide plate 24 is slidably connected to the inner side of the connecting support plate 31 through the limiting rail 27, so that the friction slide plate 24 can slide inside the connecting support plate 31 and the inner hole lever 21.

[0033] As a further implementation of this solution, the inner rotating ball 41 is spherical in shape, and an installation groove is provided on the inner side of the inner rotating ball 41. Part of the inner rotating ball 41 protrudes from the top and bottom of the connecting support plate 31. The straight column 42 is cylindrical in shape, and the left-view shape of the folding plate 43 is "U". This can greatly reduce the phenomenon of the curb stone shaking and reduce the probability of the curb stone causing accidental injury to the staff during transportation.

[0034] Workflow: When the device needs to lift a curbstone during use, move the device to the top of the curbstone, place the clamping jaws 46 on both sides of the curbstone, and press down on the handle 1. Utilizing the lever principle, the other end of the inner lever 21 tilts upward, causing the inner lever 21 to move the connecting support plate 31 upward. The connecting support plate 31, through the inner rotating ball 41, moves the straight column 42 and the device at the lower end of the straight column 42 upward. At this time, the wire rope 45 pulls the two lugs at the upper end of the clamping jaws 46, causing the two clamping jaws 46 to rotate towards the curbstone, clamping... The claw 46 grips the curbstone, at which point the two steel wire ropes 45 on both sides move closer together. Before the curbstone is lifted, the level 44, which passes through the inside of the folding plate 43, determines whether the straight column 42 is in a vertical position. Simultaneously, when gripping the curbstone, the straight column 42 drives the inner rotating ball 41 to rotate inside the arc-shaped ball hole 32 in the connecting support plate 31. The steel ball 33 inside the connecting support plate 31 fits against the outer side of the inner rotating ball 41, reducing the friction during the rotation of the inner rotating ball 41. When the straight column 42 is in a vertical position, the curbstone can be lifted, and simultaneously pushed... Push handle 26 moves the built-in slide rod 25, which in turn moves the friction slide plate 24. The friction slide plate 24 is slidably connected to the inside of the polyhedral groove 22 of the inner lever 21 via a limiting rail 27, which improves the stability of the friction slide plate 24 during movement and also limits its movement. The built-in slide rod 25 slides inside the polyhedral groove 22. At this time, the friction slide plate 24 causes the spring 23 to deform. Under the elastic force of the spring 23, the friction slide plate 24 is kept away from the inner rotating ball 41. When the friction plate 24 is in contact with the outer side of the inner rotating ball 41, the friction between the friction plate 24 and the inner rotating ball 41 reduces the rotation speed of the inner rotating ball 41, further improving the stability of the curb stone lifting, greatly reducing the swaying phenomenon during curb stone lifting, and reducing the probability of the curb stone colliding with the gas curb stone. When the curb stone is moved, the inner rotating ball 41 rotates continuously inside the arc-shaped ball hole 32, which can greatly reduce the swaying phenomenon of the curb stone and reduce the probability of the curb stone causing accidental injury to the staff during transportation.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
