[0002] The wheel assembly is a key component for the operation of bridge, gantry, portal and other types of cranes. The wheel assembly is very close to the ground or the beam. To ensure the normal operation of the wheel, it is necessary to regularly add grease to the inside. Each time new grease is added, the old grease inside the previous period must be squeezed out. At the same time, during the use of the equipment, the grease inside the wheel assembly will also flow out from the gap between the wheel axle structure and the end cover, especially in the summer when the ambient temperature is high.

[0003] At present, the grease flowing out from the wheel assembly on the crane directly accumulates on the ground or beam next to the crane track, which is difficult to clean and seriously affects the on-site environment. The accumulated grease also poses a safety hazard that may cause operators and maintenance personnel to slip and fall. The outflowing old grease cannot be effectively recycled, causing certain economic losses.

[0004] Therefore, how to provide a wheel set that can overcome the existing technical problems, collect and utilize old grease, and reduce the safety hazards of lifting equipment operators and maintenance personnel has become a technical problem that needs to be urgently solved by technical personnel in this field.

[0031] like Figures 1 to 6As shown, the wheel set provided by the embodiment of the present invention includes: a wheel axle structure 2; a bearing seat 1 arranged at both ends of the wheel axle structure 2; a wheel plate structure 3 installed on the wheel axle structure 2; an oil receiving device 4 detachably installed on the side of the bearing seat 1 close to the wheel plate structure 3; the oil receiving device 4 includes: an oil receiving base 41 detachably connected to the bearing seat 1; an oil receiving box body 42 detachably installed on the oil receiving base 41 for accommodating the flowing grease. Compared with the prior art, the present invention provides a technical solution for a wheel group. Due to the innovative structural design of the oil receiving box body 42 and the oil receiving base 41, the wheel group can be used on a crane to effectively solve the problems of grease overflowing from between the wheel shaft 2 and the bearing seat 1 when the crane is working or the wheel group is greased, flowing to the ground and polluting the environment and the grease being difficult to collect thoroughly. At the same time, it can also reduce the risk of equipment operators slipping and falling due to grease flowing to the ground at will, and it is also convenient for the collection and reuse of spilled grease. Compared with the prior art, it can significantly save the use and maintenance costs of the crane. In addition, the present invention also relates to a crane, including the wheel group as described above, which also has the above-mentioned technical effects.

[0032] Specifically, in the specific embodiment of the present utility model, the oil receiving box body 42 includes: a box body 422 detachably mounted on the oil receiving base 41;

[0033] The handle structures 421 are provided at both ends of the side walls of the box body 422 ; the handle structures 421 and the box body 422 are integrally formed.

[0034] In an embodiment of the utility model, after the box body 422 is full of grease, in order to facilitate the transfer of the grease into a special container, the box body 422 is provided with a handle structure 421 on the edge of the side wall, so that it is easy to hold and convenient for pouring the grease in the box body 422 into the special container. More specifically, the outer edge of the box body 422 is provided with a diversion port structure for diversion.

[0035] Specifically, in a specific embodiment of the present utility model, the oil receiving base 41 includes: a base connecting arm 411 detachably connected to the bearing seat 1; and a base body 412 connected to the base connecting arm 411 .

[0036] Specifically, in a specific embodiment of the present invention, the base connecting arm 411 is vertically connected to the base body 412, and more specifically also includes: a protective film layer 5 provided at the connection position between the base connecting arm 411 and the bearing seat 1.

[0037] Specifically, in a specific embodiment of the present utility model, the oil receiving base 41 and the oil receiving box body 42 are detachably connected in the following manner: the inner bottom of the oil receiving base 41 is detachably connected to the bottom of the oil receiving box body 42; the inner peripheral wall of the oil receiving base 41 is detachably connected to the side wall of the oil receiving box body 42.

[0038] In a specific embodiment of the present invention, due to the detachable connection between the oil receiving base 41 and the oil receiving box body 42 and the layout of the position of the oil receiving base 41, it is possible to collect the grease flowing out from the wheel group on the crane, thereby preventing the grease from directly accumulating on the ground or beam body next to the crane track, which is difficult to clean and may cause safety hazards such as slips and falls of operators and maintenance personnel. In addition, the oil receiving box body can be disassembled and the grease inside it can be transferred to a dedicated container. Compared with the existing technology, the outflowing old grease can be effectively recycled.

[0039] Specifically, in the embodiment of the present invention, the bottom plate of the box body 422 forms an angle of 5° to 15° with the horizontal plane. More specifically, in the embodiment of the present invention, the bottom plate of the box body 422 forms an angle of 8° to 12° with the horizontal plane.

[0040] In a specific embodiment of the present invention, in order to facilitate the automatic concentration and pouring of the grease in the box body 422 more quickly and thoroughly, the bottom plate of the box body 422 is at a certain angle to the horizontal plane, preferably 8° to 12°, so that the grease in it can be poured more conveniently.

[0041] Specifically, in this embodiment of the present invention, the removable connection between the oil receiving base 41 and the oil receiving box body 42 is achieved by providing a rotating shaft on the inner side of the oil receiving base 41, and removably attaching the oil receiving box body 42 to the rotating shaft. More specifically, this embodiment of the present invention further includes a locking buckle structure mounted on the oil receiving box body 42, which is used to lock the relative position of the oil receiving box body 42 and the oil receiving base 41.

[0042] In addition, an embodiment of the present invention also provides a crane, including the wheel set as described above, which also has the above technical effects.

[0043] To elaborate more specifically, the wheel assembly on bridge, gantry, portal, and other types of cranes is a key component in the operation of the crane. It operates frequently and is very close to the ground or beams. To ensure the normal operation of the wheels, they need to be regularly filled with grease. Each time new grease is added, the old grease inside the wheel assembly must be squeezed out. At the same time, during the use of the equipment, the grease inside the wheel assembly will also flow out from the gap between the wheel axle structure and the end cover, especially in the summer when the ambient temperature is high. Currently, the grease that flows out of the wheel assembly on the crane directly accumulates on the ground or beams next to the crane track, seriously affecting the site environment and the cleanliness of the crane. It is difficult to clean it thoroughly, and the grease accumulation also poses a safety hazard that may cause operators and maintenance personnel to slip and fall. In addition, the old grease that flows out cannot be effectively recycled, resulting in certain economic losses.

[0044] Against this backdrop, the present invention aims to address the numerous adverse effects of grease leaking from existing wheel assemblies by providing a wheel assembly with a simple structure, convenient collection and utilization of old grease, and reduced safety hazards for crane operators and maintenance personnel. The wheel assembly involved in the present invention is primarily composed of a bearing seat 1, a wheel axle structure 2, a wheel plate structure 3, and an oil receiving device 4. The wheel plate structure 3 is disposed in the middle of the wheel axle structure 2, the bearing seat 1 is disposed at both ends of the wheel axle structure 2, and the oil receiving device 4 is disposed on the side of the bearing seat 1 near the wheel plate structure 2, near the ground. The oil receiving device 4 primarily comprises an oil receiving base 41 and an oil receiving box 42. The oil receiving base 41 is disposed on the side of the bearing seat 1, adjacent to the bearing seat, and is used to support the oil receiving box 42. The oil receiving box 42 is detachably connected to the oil receiving base 41, specifically detachably connected at the bottom and the side. The oil receiving box 42 is a box structure with an upper opening, and is used to collect grease that overflows from between the wheel axle structure 2 and the bearing seat 1 during crane operation or when the wheel assembly is being refilled with grease. When the oil box 42 is full, a handle is provided on the sidewall of the box 42 to facilitate the transfer of the oil into the dedicated container. This handle facilitates gripping and allows the oil in the oil box 42 to be poured into the dedicated container. Furthermore, to facilitate automatic collection and quicker and more thorough pouring of the oil in the oil box 42, the bottom plate of the oil box 42 is angled with the horizontal plane, allowing the pouring depth to be greater near the end of the oil box 42 connected to the base or at the connection.

[0045] In summary, the crane wheel assembly of the present invention can effectively solve the problems of grease overflowing from between the wheel axle structure 2 and the bearing seat 1 when the crane is working or the wheel assembly is greased, flowing to the ground and polluting the environment and the grease being difficult to collect thoroughly. At the same time, it can also reduce the risk of equipment operators slipping and falling due to grease flowing to the ground at will, and it is also convenient for the collection and reuse of spilled grease, saving use costs. Compared with the existing technology, it has significant technical effects.
