DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of clear narration, rather than to limit the scope of implementation of the present utility model. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of implementation of the present utility model.

[0022] Reference Figures 1 - 3 , an axle with a hydraulic slewing bearing, comprising an axle rod 1, fixing brackets 2 symmetrically and fixedly installed on the surface of the axle rod 1, a plurality of mounting blocks 14 fixedly installed on the fixing brackets 2, support rods 3 rotatably installed on each of the plurality of mounting blocks 14, and a support frame 4 provided above one end of the fixing bracket 2 away from the axle rod 1;

[0023] On one side of the support frame 4 close to the fixing bracket 2, a plurality of fixing blocks 13 are fixedly installed. One end of the support rod 3 away from the mounting block 14 is rotatably connected to the fixing block 13. On one side of the support frame 4 close to the fixing bracket 2, a hydraulic cylinder 10 is fixedly installed, and the output shaft of the hydraulic cylinder 10 is fixedly connected to the fixing bracket 2.

[0024] When the axle is lifted or lowered, the hydraulic cylinder 10 can be started, and the output shaft of the hydraulic cylinder 10 drives the fixing bracket 2 to move downward, and the movement of the fixing bracket 2 drives the axle rod 1 to move downward. When the fixing bracket 2 moves, the mounting block 14 moves with the fixing bracket 2. When the mounting block 14 moves, the support rod 3 will rotate with the movement of the mounting block 14. Since the support rods 3 cross each other, they can support the fixing bracket 2 and the support frame 4, and can effectively support the lifting device when the axle is lifted or lowered, avoiding damage to the lifting device caused by the vehicle's own gravity, enhancing the stability of the axle, and improving safety.

[0025] On one side of the support frame 4 away from the fixing bracket 2, a rotating rod 7 is fixedly installed. On the rotating rod 7, a fixing plate 8 is fixedly installed. A fixing component is provided on the fixing plate 8 for fixing the fixing plate 8. The fixing component includes fixing grooves symmetrically opened at both ends of the fixing plate 8, clamping blocks 11 slidably installed in the fixing grooves, and fixing springs 12 fixedly installed on the inner bottom surface of the fixing grooves. One end of the fixing spring 12 away from the inner bottom surface of the fixing groove is fixedly connected to the clamping block 11. When the axle needs to be installed on the corresponding vehicle, the fixing plate 8 can be aligned with the installation groove of the vehicle to be installed, and the clamping block 11 is clamped with the corresponding installation groove by the elastic force of the fixing spring 12, thus completing the installation. At the same time, the axle can be slewing-supported through the rotating rod 7, improving the flexibility of the axle.

[0026] A shock-absorbing component is provided on the support frame 4 for shock-absorbing the support frame 4. The shock-absorbing component includes a plurality of shock-absorbing springs 5 fixedly installed at the top of the support frame 4 and a shock-absorbing plate 6 fixedly installed above the support frame 4. One side of the shock-absorbing plate 6 close to the support frame 4 is fixedly connected to the shock-absorbing spring 5. A rotating groove is opened on the shock-absorbing plate 6, and the rotating groove is rotatably sleeved with the rotating rod 7. During the driving process of the vehicle, vibrations will occur. The elastic force of the shock-absorbing spring 5 weakens the vibrations, improving the stability of the axle.

[0027] One end of the fixing bracket 2 close to the axle rod 1 is symmetrically provided with threaded holes, and fixing nuts 9 are threadedly inserted into the threaded holes. The fixing bracket 2 can be effectively fixed on the axle rod 1 through the fixing nuts 9, preventing the fixing bracket 2 from loosening.

[0028] The lower surface of the fixing bracket 2 is fixedly connected with an anti-slip layer made of rubber, which can effectively enhance the friction between the fixing bracket 2 and the axle rod 1, prevent the fixing bracket 2 from loosening, and improve the stability of the axle.

[0029] In the present utility model, when the axle is lifted or lowered, the hydraulic cylinder 10 can be started. The output shaft of the hydraulic cylinder 10 drives the fixing bracket 2 to move downward, and the movement of the fixing bracket 2 drives the axle rod 1 to move downward. When the fixing bracket 2 moves, the mounting block 14 moves with the fixing bracket 2. When the mounting block 14 moves, the support rods 3 will rotate with the movement of the mounting block 14. Since the support rods 3 cross each other, they can support the fixing bracket 2 and the support frame 4, effectively supporting the lifting device when the axle is lifted or lowered, preventing the lifting device from being damaged due to the vehicle's own gravity, enhancing the stability of the axle, and improving safety.

[0030] Generally speaking, for the technical problem: the existing axle with a hydraulic slewing bearing cannot support the lifting device during lifting, and it is easy for the lifting device to be damaged due to the vehicle's own gravity during the lifting process, reducing the stability of the axle; the technical solution adopted is: through the mutual cooperation of the mounting block 14, the fixing block 13, the support rods 3, the support frame 4 and the fixing bracket 2, the lifting device can be effectively supported when the axle is lifted or lowered, preventing the lifting device from being damaged due to the vehicle's own gravity, enhancing the stability of the axle, and improving safety; because the implementation process of the technical solution is: when the axle is lifted or lowered, the hydraulic cylinder 10 can be started. The output shaft of the hydraulic cylinder 10 drives the fixing bracket 2 to move downward, and the movement of the fixing bracket 2 drives the axle rod 1 to move downward. When the fixing bracket 2 moves, the mounting block 14 moves with the fixing bracket 2. When the mounting block 14 moves, the support rods 3 will rotate with the movement of the mounting block 14. Since the support rods 3 cross each other, they can support the fixing bracket 2 and the support frame 4. Therefore, this technical problem can definitely be solved, and the achieved technical effect is: the lifting device can be effectively supported when the axle is lifted or lowered, preventing the lifting device from being damaged due to the vehicle's own gravity, enhancing the stability of the axle, and improving safety.

[0031] In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "connection", "fixation" should be understood in a broad sense.

[0032] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
