Embodiment Construction

[0008] The embodiment is described in detail in conjunction with the above drawings. The protective cover is composed of an arc-shaped plate 1 and a bent plate 2. The arc-shaped plate is semicircular and unsealed. The upper part of the bent plate is semicircular and the lower part is folded outward. The two end surfaces of the curved plate are respectively equipped with bent plates, the semicircular shape of the upper part of the bent plate just coincides with the end surface of the curved plate, and there are bolt holes on the folded edge 3 of the lower part of the bent plate, which are fixed on the trolley frame by bolts Above, there is a clearance fit between the protective cover and the pulley, and there are at least two observation holes on the arc-shaped plate. Since there is a gap between the protective cover and the pulley, it can prevent the wire rope from going off the rope at the same time. The combination of the bolt and the nut can adjust the height of the protecti...

Abstract

The invention discloses a protective cover for a fixed pulley of a crane trolley. The protective cover comprises a trolley frame, and consists of an arc-shaped plate and bent plates; the arc-shaped plate is in the shape of semi-circular ring, and is not sealed; the upper parts of the bent plates are semi-circular, and the lower parts of the bent plates are outwards folded; the two end surfaces of the arc-shaped plate are separately equipped with the bent plates; folded sides on the lower parts of the bent plates are equipped with bolt holes, and are fixedly arranged on the trolley frame through bolts; and at least two or more observation holes are formed in the arc-shaped plate. The protective cover is in clearance fit to a pulley sheet. The semicircular shapes of the upper parts of the bent plates just fit to those of end surfaces of the arc-shaped plates; and the bolts are combined with nuts for regulating height of the protective cover and the slide wheel sheet. According to the technical scheme adopted by the invention, the protective cover achieves the protection effect, further can observe a condition when a steel wire rope works, can prevent the steel wire rope from dropping out of a slot, and has the advantages of being simple in structure, convenient to regulate, and the like.

Description

Technical field: [0001] The invention relates to a protective cover, which is especially suitable for matching with the fixed pulley of the crane trolley. Background technique: [0002] According to the requirements of relevant national standards, protective measures must be taken for the rotating parts, especially the protection on the fixed pulley of the crane trolley. The conventional protective measures are only shielding. The second is that the height cannot be adjusted. Invention content: [0003] The task of the present invention is to propose a protective cover for the fixed pulley of a crane trolley which is simple to manufacture, can play a protective role, and can also prevent the steel wire rope in the pulley from de-grooving. [0004] The task of the present invention is accomplished in this way, which includes a trolley frame, characterized in that the protective cover is composed of an arc-shaped plate and a bent plate, the arc-shaped plate is semicircular ...
