Description

Technical Field

[0001] The utility model belongs to the technical field of construction fans and is particularly suitable for a plateau construction fan with assembled outriggers. Background Art

[0002] In recent years, with the rapid development of national infrastructure projects, more and more long and large tunnels are being constructed in China, especially in plateau areas. Construction fans are mostly installed on steel supports when used on site. At the same time, they are used on different steel supports at different times. The crossbeam spans of different steel supports are often different. At present, the legs of construction fans are mostly welded square legs, which are directly welded on the fan housing. The position of the legs is relatively fixed and the installation surface is small. When the construction fan is installed on steel supports with different crossbeam spans, the legs often cannot be properly placed on the support beams. In addition, the legs directly welded on the construction fan housing will cause the housing to be welded and deformed, and long-term use will also cause local deformation of the housing. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned defects and provide a plateau construction fan with assembled legs, so that it can adapt to steel brackets with various beam spans, while reducing the amount of casing welding, reducing the risk of casing deformation, and at the same time ensuring firm and reliable installation.

[0004] The technical solution of the utility model: a plateau construction fan with assembled legs, characterized in that: the plateau construction fan with assembled legs comprises a fan body and assembled legs, the fan body is provided with a flange, the assembled legs are composed of two leg assemblies and two angle steel supports, the leg assemblies are composed of a vertical plate, a bottom plate, a side plate, and a reinforcing plate, the side plates are formed by bending the two sides of the vertical plates, the bottom plate is bent by the bottom of the vertical plates to become a long strip, the side plates are welded together with the bottom plates, the side surfaces of the reinforcing plates are welded to the vertical plates, and the bottom surfaces are welded to the bottom plates, the upper parts of the vertical plates are arc edges and are provided with strip holes I uniformly distributed around the circumference, the side plates are provided with ear holes and strip holes II, mounting holes are provided at both ends of the angle steel supports, the angle steel supports are fixedly connected to the two leg assemblies by bolt pairs, and the assembled legs are connected to the fan flange by bolt pairs.

[0005] The utility model has the beneficial effects that: the assembled legs are connected to the flange of the fan body through bolt pairs, which reduces the welding amount of the casing and reduces the risk of casing deformation. The assembled legs directly support the flange, which has reliable strength and can also avoid deformation of the casing and leg welds due to long-term stress. The side panels are formed by bending the two sides of the vertical panels, and the bottom panels are formed by bending the bottom of the vertical panels, which not only strengthens the strength of the vertical panels but also reduces the welding amount. The leg assembly is provided with vertical panels, bottom panels, side panels, and reinforcing panels, and the overall strength is reliable. At the same time, the bottom panel is long and has a large contact area, which can be well placed on different steel brackets and adapt to various beams with different spans. The upper part of the vertical panel is provided with strip holes I evenly distributed around the circumference, which is convenient for adjusting the position during installation. The side panels are provided with lifting ear holes, which is also convenient for hoisting the fan, avoiding the casing being pulled and deformed by directly hoisting the casing. The angle steel support is fixedly connected to the two leg assemblies through bolt pairs, making the leg assembly more stable. BRIEF DESCRIPTION OF THE DRAWINGS
