Description

Technical Field

[0001] The utility model relates to the technical field of double-beam crane traveling wheels, in particular to a double-beam crane traveling wheel bearing protection device. Background Art

[0002] At present, during the construction of earth pressure shield, due to the serious leakage of mud and slag from the belt conveyor, the bearings of the double-beam crane's travel wheels are frequently damaged, seriously affecting the efficiency of shield construction. In addition, the replacement of the bearings requires the dismantling of the entire double-beam crane, which takes a long time to repair. In addition, when passing under important risk sources, long-term abnormal shutdowns pose a high construction risk and cannot meet construction needs. Therefore, in order to reduce the frequent damage of the double-beam crane's travel wheel bearings, designing a double-beam crane's travel wheel bearing protection device is an issue that technical personnel in related fields urgently need to solve. Utility Model Content

[0003] In order to solve the above technical problems, the technical solution provided by the utility model is: a double-beam crane travel wheel bearing protection device, which is arranged on the double-beam crane travel wheel and travel wheel bearing, including a sleeve arranged on the outside of the travel wheel bearing, a blind cover arranged on the side of the travel wheel away from the sleeve, and a through cover arranged on the side of the travel wheel close to the sleeve. The outer edges of the blind cover and the through cover are fixed to the travel wheel by several fixing bolts.

[0004] Furthermore, a sealing ring installation groove is provided on the outer edge of the blind cover and the open cover respectively, and an O-ring is provided in the sealing ring installation groove.

[0005] Furthermore, a second sealing ring installation groove is provided on the inner side of the shaft sleeve, and a second O-ring is provided in the second sealing ring installation groove.

[0006] Furthermore, the diameters of the blind cover and the open cover are smaller than the diameter of the running wheel.

[0007] The advantages of the present invention over the prior art are that the present invention can ensure the normal operation of the traveling wheel while reducing the damage to the bearing caused by the ingress of mud and sand by adding a blind cover, a through cover, a shaft sleeve and corresponding sealing rings and fixing them, thereby achieving the purpose of protecting the traveling wheel bearings.

[0011] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0012] In the description of the embodiments of the present invention, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the product of the utility model is usually placed when in use. It is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0013] Furthermore, the use of terms such as "horizontal," "vertical," and "overhanging" does not necessarily imply that the component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0014] In the description of the embodiments of the present invention, “a plurality of” means at least 2.

[0015] In the description of the embodiments of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0016] Example:

[0017] A double-beam crane travel wheel bearing protection device is arranged on the double-beam crane travel wheel 1 and the travel wheel bearing 2, including a sleeve 3 arranged on the outside of the travel wheel bearing 2, a blind cover 4 arranged on the side of the travel wheel away from the sleeve 3, and a through cover 5 arranged on the side of the travel wheel close to the sleeve 3. The outer edges of the blind cover 4 and the through cover 5 are fixed to the travel wheel by several fixing bolts 6.

[0018] The outer edges of the blind cover 4 and the open cover 5 are respectively provided with a sealing ring mounting groove 7, and an O-ring 8 is provided in the sealing ring mounting groove 7; the inner side of the shaft sleeve 3 is provided with a sealing ring mounting groove 2 9, and an O-ring 2 10 is provided in the sealing ring mounting groove 2 9; the diameters of the blind cover 4 and the open cover 5 are smaller than the diameter of the running wheel.

[0019] During the specific implementation, the size of the through cover, blind cover and shaft sleeve is first customized according to the size of the traveling wheel and bearing, and a groove is milled inside the blind cover to install the O-ring, and four bolts are used on the outside to fix it to the traveling wheel; at the same time, two grooves are milled on the inside of the through cover, and an O-ring is also installed, and four bolts are used to fix it to the traveling wheel; in addition, a groove is milled on the shaft, and the shaft sleeve is installed after installing the O-ring, and finally the assembled traveling wheel is installed on the double-beam crane; by adding the blind cover, through cover, shaft sleeve and corresponding sealing ring and fixing them, the normal operation of the traveling wheel can be guaranteed while reducing the damage to the bearing caused by the ingress of mud and sand, thereby achieving the purpose of protecting the traveling wheel bearing.
