Description

Technical Field

[0001] The utility model relates to the technical field of crane equipment, and more specifically to a crane driving wheel group. Background Art

[0002] A crane refers to a multi-action lifting machinery that can vertically lift and horizontally carry heavy objects within a certain range. The working characteristics of some lifting equipment are intermittent movements, that is, the corresponding mechanisms of material picking, transportation, unloading and other actions work alternately in one working cycle. The development and use of cranes in the market are becoming more and more extensive. The driving wheel group of the crane is an important component of the crane, which mainly supports and drives the crane to move. It is connected to the power system of the crane through a transmission device, thereby driving the crane to move.

[0003] The shortcomings of the prior art: During use, the active wheel group of the crane in the prior art usually needs to bear the pressure and friction of heavy objects, which can easily cause wear on the wheel surface. The wear on the wheel surface will directly affect the walking stability and service life of the crane. At the same time, since the crane will be subjected to uneven force during the movement of heavy objects, the wheel group will also be uneven, which can easily affect the driving effect of the active wheel group. Utility Model Content

[0004] In order to overcome the above defects of the prior art, the utility model provides a crane driving wheel group to solve the problems existing in the above background technology.

[0005] The utility model provides the following technical solutions: a crane active wheel group, comprising a driving motor and a wheel body, wherein the output end of the driving motor is fixedly connected to a central axis, the wheel body is fixedly connected to the outer surface of the central axis, the middle parts of the left and right ends of the wheel body are fixedly connected to fixed seats, the left and right ends of the wheel body are fixedly connected to guide rings, the top surface of the guide ring is fixedly connected to a reinforcing rib, a guide rail is arranged below the wheel body, the top end of the guide rail is provided with two movable grooves at equal distances, the bottom end of the guide rail is provided with two sliding grooves at equal distances, and the inner cavity of the sliding groove is movably connected to a balancing component.

[0006] Preferably, the wheel body is made of high-strength, high-toughness alloy steel or cast iron material, and the outer surface of the wheel body is sprayed with a wear-resistant layer.

[0007] Preferably, the position of the reinforcing rib corresponds to the position of the movable groove, and the reinforcing rib is movably connected to the inner cavity of the movable groove.

[0008] Preferably, the balancing assembly includes a ring, the bottom end of the ring is fixedly connected to a support rod, the bottom end of the support rod is fixedly connected to a limiting plate, the end of the limiting plate away from the support rod is fixedly connected to a sliding block, an installation groove is opened in the middle of the top end of the sliding block, and a roller is fixedly installed in the middle of the inner cavity of the installation groove.

[0009] Preferably, the diameter of the inner cavity of the collar is matched with the diameter of the outer surface of the central shaft, and the collar is sleeved on the outer surface of the central shaft.

[0010] Preferably, the shape and size of the sliding block are matched with the shape and size of the inner cavity of the sliding groove, and the sliding block and the roller are movably connected to the inner cavity of the sliding groove.

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model increases the strength of the wheel set and improves the wear resistance of the wheel by adopting a wheel body made of high-strength and high-toughness alloy steel or cast iron material. At the same time, a wear-resistant layer is sprayed on the outer surface of the wheel body to form a surface layer with good wear resistance on the wheel surface to improve the wear resistance of the wheel. The guide ring on the outer surface of the wheel body ensures the stability of the wheel when running on the guide rail. At the same time, the weighing effect of the wheel is increased by reinforcing ribs to reduce the possibility of compression deformation of the wheel.

[0013] 2. The utility model provides balancing components on both sides of the wheel body to ensure that the wheel group is evenly stressed. When the crane moves to carry heavy objects, the wheel group also bears the load. When uneven stress is encountered, the wheel group may tilt due to the uneven stress. The wheel body is supported by a support rod and a limit plate, and the sliding block is movably installed in the inner cavity of the sliding groove. As the wheel group moves, the sliding block and the roller also move in the inner cavity of the sliding groove. While the wheel body remains balanced, the stability of the wheel group moving on the track is guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Furthermore, the wheel body 2 is made of high-strength, high-toughness alloy steel or cast iron material, which can effectively increase the strength of the wheel set. The outer surface of the wheel body 2 is sprayed with a wear-resistant layer, and a surface layer with good wear resistance is formed on the surface of the wheel body 2 to improve the wear resistance of the wheel. The position of the reinforcing rib 6 corresponds to the position of the movable groove 8. The reinforcing rib 6 is movably connected to the inner cavity of the movable groove 8. The movable groove 8 ensures the stability of the wheel body 2 in moving on the guide rail 7. The compressive strength of the wheel body 2 is increased by the reinforcing rib 6 to avoid deformation of the outer surface of the wheel body 2 and the guide ring 5 after long-term use, thereby increasing the service life of the wheel set.
