[0002] A tire crane is a lifting device that is convenient for moving and adapting to different construction sites. It can move freely on various terrains and conditions without additional foundation or support structures. This machine is usually equipped with a powerful engine and operating system, capable of performing efficient lifting operations and precise position adjustment. Tire cranes are widely used in construction sites, port terminals, industrial facilities, and other temporary engineering sites, providing flexible and reliable solutions for various engineering tasks.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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 the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Referring to Figures 1-3 , an embodiment provided by the present utility model: a traveling and steering device for a tire crane, including a frame 1, a motor 2 is fixedly connected to the top of the frame 1, a first gear 3 is fixedly connected to the output end of the motor 2, the first gear 3 is rotatably connected to the bottom of the frame 1, a rack 4 is slidably connected to the bottom of the frame 1, the first gear 3 meshes with the rack 4, a fixed column 5 is fixedly connected to one side of the rack 4, a rotating rod 6 is rotatably connected to the outer wall of the fixed column 5, a support column 7 is fixedly connected to the bottom of the frame 1, an L-shaped rod 8 is rotatably connected to the outer wall of the support column 7, one side of the L-shaped rod 8 is rotatably connected to the bottom of the rotating rod 6, the other side of the L-shaped rod 8 is fixedly connected to an axle 9, a moving wheel 10 is rotatably connected to the outer wall of the axle 9, a second gear 11 is rotatably connected to the bottom of the frame 1, a connecting component is provided at one end of the second gear 11, and the connecting component is used to drive the second gear 11 to rotate. The connecting component includes a connecting rod 12, one side of the two connecting rods 12 is fixedly connected to one end of the second gear 11, and the other side of the two connecting rods 12 is fixedly connected to one end of the first gear 3.

[0033] Specifically, when the crane needs to turn during the moving process, the motor 2 drives the first gear 3 to start rotating through its output end. The first gear 3 comes into contact with the engaged rack 4, guiding the rack 4 to slide along the track, thereby driving the fixed column 5 to move horizontally. The fixed column 5 drives the connected rotating rod 6 to start rotating, and the L-shaped rod 8 connected to the rotating rod 6 rotates on the outer wall of the support column 7. The L-shaped rod 8 pushes the connected axle 9 on one side to move, thereby activating the connected moving wheel 10 on the outer wall to start turning. At the same time, the movement of the first gear 3 also drives the connecting rod 12 to act, and the connecting rod 12 causes the second gear 11 to start rotating, thereby driving the rear wheels to turn. Through the rotation of multiple moving wheels 10, the crane can adjust its moving direction to achieve an accurate turning effect.

[0034] Referring to Figure 1 and Figure 4 , a support frame 13 is fixedly connected to the top of the frame 1, a fixed frame 14 is fixedly connected to the top end of the support frame 13, a support rod 15 is slidably connected inside the fixed frame 14, a plurality of limiting grooves 16 are opened inside the support rod 15, a crank 20 is rotatably connected inside a connecting frame 19, a spiral bar 21 is fixedly connected to one end of the crank 20, and the outer wall of the spiral bar 21 is slidably connected inside the limiting groove 16.

[0035] Specifically, when it is necessary to adjust the lifting height of the crane, by rotating the crank 20, the force applied causes the spiral bar 21 connected to one end to move inside the limit groove 16. Under the action of the limit groove 16, the spiral bar 21 pushes the support rod 15 to slide inside the fixed frame 14, and then drives the boom connected to the top to perform precise lifting adjustment, achieving the lifting effect.

[0036] Refer to Figure 1 and Figure 4 A fixed rod 17 is fixedly connected to one side of the fixed frame 14. A rotating frame 18 is rotatably connected to the outer wall of the fixed rod 17. A connecting frame 19 is fixedly connected to one side of the rotating frame 18. A cam 22 is rotatably connected inside the rotating frame 18. A handle 23 is fixedly connected to the outer wall of the cam 22.

[0037] Specifically, once adjusted to the appropriate height, by rotating the handle 23, the cam 22 is guided to rotate inside the rotating frame 18. The outer wall of the cam 22 abuts against one side of the fixed frame 14, causing the rotating frame 18 and the connecting frame 19 to rotate accordingly, ensuring that the spiral bar 21 is correctly inserted into the limit groove 16 inside the support rod 15, thereby fixing the boom at the required height position.

[0038] Working principle: When the crane needs to turn during the moving process, first, the output end of the motor 2 drives the first gear 3 to rotate. The first gear 3 drives the engaged rack 4 to slide under force. The rack 4 drives the fixed column 5 to move under force. The fixed column 5 drives the rotating rod 6 connected to its outer wall to rotate under force. The rotating rod 6 drives the L-shaped rod 8 connected to one side to rotate on the outer wall of the support column 7. The L-shaped rod 8 drives the axle 9 connected to one side to rotate. The axle 9 drives the moving wheel 10 connected to its outer wall to rotate. At the same time, when the first gear 3 rotates, it also drives the two connecting rods 12 connected to one end to move. The connecting rods 12 drive the second gear 11 connected to one side to rotate, and then the rear wheels rotate. By the rotation of the front and rear moving wheels 10, the moving direction of the crane is adjusted, thus achieving the effect that the crane is convenient to move and turn. When it is necessary to adjust the lifting height, the crank 20 can be rotated, and the force applied causes the spiral bar 21 connected to one end to move inside the limit groove 16. Through the limit between the spiral bar 21 and the limit groove 16, the support rod 15 is pushed to slide inside the fixed frame 14 under force. The support rod 15 drives the boom connected to the top to lift. When adjusted to the appropriate position, at this time, the handle 23 is rotated, and the force applied causes the cam 22 to rotate inside the rotating frame 18. When the cam 22 rotates, its outer wall abuts against one side of the fixed frame 14 and drives the rotating frame 18 and the connecting frame 19 to rotate, and then the spiral bar 21 is inserted into the limit groove 16 inside the support rod 15 to complete the fixation, thereby achieving the effect that the lifting height can be adjusted.

[0039] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
