Abstract
Description
Technical Field
[0001] The utility model relates to a wheel insulation device, which is particularly suitable for cranes with extremely high requirements on insulation and safety. Background Art
[0002] Insulated bridge crane is a specially designed lifting equipment, mainly used for lifting operations in power systems, aluminum electrolytic plants, steel mills and other places. Its main feature is that it has good insulation performance, which can ensure that operators can work safely in an environment with electric current. Insulated bridge cranes must meet the three-level insulation requirements, and wheel insulation is one of them. The insulated wheel structure is mostly angle box type, and an insulating plate is placed between the angle box and the frame to achieve insulation between the wheel and the frame. Its insulation protection measures are relatively simple, but it is inconvenient to inspect and load and unload. The 45° split wheel structure is easier to replace and maintain than the angle box wheel, but the 45° split wheel has one half ring directly welded to the frame and two half rings wrapped around the wheel, so the insulation of the split wheel has always been difficult to achieve. Utility Model Content
[0003] The technical problem to be solved by the utility model is: how to carry out insulation design for a 45-degree split wheel. The utility model provides a split wheel insulation device.
[0004] In order to achieve the above object, the utility model is realized by the following technical solutions:
[0005] A split wheel insulation device comprises a split wheel group, the split wheel group comprises a central split wheel bearing box and a wheel group, a wheel insulation sleeve is arranged on the outer side of the split wheel group, the wheel insulation sleeve comprises a first semi-annular insulation plate and a second semi-annular insulation plate, wherein a first protrusion is arranged on the outer ring side of the first semi-annular insulation plate, and a first groove is arranged on the inner ring side; a second groove is arranged on the outer ring side of the second semi-annular insulation plate, and a second protrusion is arranged on the inner ring side, the first protrusion cooperates with the second groove, and the first groove cooperates with the second protrusion; the split wheel group is a 45° split wheel group.
[0006] The first semi-annular insulating plate and the second semi-annular insulating plate are made of epoxy resin plate or SMC insulating plate, and the thickness thereof is 10-20 mm.
[0007] Compared with the prior art, the utility model has the following beneficial effects: an insulating wheel with a 45° split structure is designed and installed on an insulating crane, which improves the convenience of wheel disassembly and maintenance and is used for cranes with insulation requirements. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 It is the overall structure diagram of the utility model;
[0009] Figure 2This is an outer side view of the utility model;
[0010] Figure 3 This is a structural diagram of the wheel insulation sleeve. DETAILED DESCRIPTION
[0011] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0012] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0013] like Figure 1 , Figure 2 , Figure 3 As shown, a split wheel insulation device includes a split wheel group 2, the split wheel group 2 includes a central split wheel bearing box 21 and a wheel group 22, a wheel insulation sleeve is arranged on the outer side of the split wheel group 2, the wheel insulation sleeve includes a first semi-annular insulation plate 1 and a second semi-annular insulation plate 3, wherein a first protrusion 11 is arranged on the outer ring side of the first semi-annular insulation plate 1, and a first groove 12 is arranged on the inner ring side; a second groove 31 is arranged on the outer ring side of the second semi-annular insulation plate 3, and a second protrusion 32 is arranged on the inner ring side, the first protrusion 11 cooperates with the second groove 31, and the first groove 12 cooperates with the second protrusion 32.
[0014] The split wheel set 2 is a 45° split wheel set 2 .
[0015] The first semi-annular insulating plate 1 and the second semi-annular insulating plate 3 are made of epoxy resin plate or SMC insulating plate, and the thickness thereof is 10-20 mm.
[0016] The working principle of the utility model is:
[0017] The first semi-circular insulating plate 1 and the second semi-circular insulating plate 3 together wrap the split wheel bearing box 21. In this way, in order to ensure assembly and insulation plate performance, the annular insulating plate is divided into two halves and buckled together to wrap the split wheel bearing box. In order to avoid the influence of air on the insulation performance, the buckling part of the two insulating plates is made into a step shape to avoid the influence of direct contact with air on the insulation performance. This 45° split insulating wheel is a new product. After practice, it can fully meet the needs of on-site use and solve the difficulty of insulating the split wheel.
[0018] The above is only a preferred embodiment of the present invention. It should be pointed out that, for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, and these should also be regarded as the protection scope of the present invention.
