CN2185744Y - Arc track rotating jib crane - Google Patents

Abstract

The utility model relates to a crane which belongs to rotating jib crane machinery, being composed of a rotating jib, a rotating component, a support seat, a lifting hoist, tracks, etc. The utility model is characterized in that one end of the rotating jib is connected with the rotating component, the upper end surface of the other end is fastened with a monorail car carriage which is suspended on an arcuate rail, and the arcuate rail is fixed on the lower end surface of a beam frame which is arranged in a building. The utility model has the advantages of good working stability, difficult bending and deformation of the rotating jib, and low craning framework. The utility model is applicable in buildings of various heights, particularly buildings with lower heights among floors.

Description

Arc track rotating jib crane

The utility model relates to a kind of hoisting crane, and it belongs to the turning crane tool.

Indoor lifting lightweight material, usually use known wall formula boom crane or as fixed column type arm full circle swinging hoist frame as described in the Chinese patent application 92205875X, though what have is simple in structure, easy for installation, the use that has is light and handy, flexibly, operation is wide, but because above-mentioned stream oriented device all adopts an end cantilever beam of pull bar pull-up tenesmus, constituted spandrel frame, thereby hoisting crane framework height, and modernized operation factory building mostly requires temperature control to dry, and need force down factory building height as far as possible, so said apparatus difficulty satisfies this requirement, Chinese patent application 902081063 described circular ring type crane in bridge type, though the lifting framework is low, this device is applicable to the circular ring type building, thereby in existing other pattern building, use then restricted, in addition, this apparatus structure is complicated, and the adjustment of its adjusting mechanism also comparatively bothers.

It is low that the purpose of this utility model provides a kind of lifting framework, adaptable arc rail turning crane.

Solution of the present utility model is such: a kind of arc rail turning crane, form by parts such as spiral arm beam, rotatable parts, supporting base, tackles, tracks, it is characterized in that spiral arm beam one end links to each other with rotatable parts, the fastening hand cart in other end upper surface, hand cart is suspended on the arc i-beam track, and the arc i-beam track is fixed on the roof beam structure lower surface that is installed in the building.

The utility model is owing to adopt the arc rail to hang an end spiral arm beam, its effect is the lifting operation good stability, the spiral arm beam is difficult for flexural deformation, the framework height is low, therefore this device is suitable for using in the building of various height, especially in modernized temperature control dries the design of factory building, use this device can reduce the construction height of building.

Below in conjunction with accompanying drawing embodiment of the present utility model is described.

Fig. 1 is the birds-eye view that can turn round the arc rail turning crane at 180 ° of angles

Fig. 2 is the A-A section-drawing

Embodiment: as Fig. 1, shown in Figure 2, supporting base ［ 11 ］ is anchored on wall column ［ 6 ］ one sides, the rotating shaft cover ［ 10 ］ that links to each other with spiral arm beam ［ 8 ］ one ends is fixed on the supporting base ［ 11 ］ by pivot pin ［ 13 ］, the electric block ［ 12 ］ that can move forward and backward is arranged on the spiral arm beam ［ 8 ］, spiral arm beam ［ 8 ］ other end upper surface is fastened with an electric monorail dolly ［ 9 ］, electric monorail dolly ［ 9 ］ is suspended on the semicircle i-beam track ［ 4 ］, electric monorail dolly ［ 9 ］ can move along semicircle i-beam track ［ 4 ］, the upper surface of this semicircle i-beam track ［ 4 ］ is fastened on the longeron ［ 2 ］ in the roof beam structure ［ 7 ］ and the lower surface of cant beam ［ 3 ］, the two ends welding iron plate ［ 1 ］ of every longeron ［ 2 ］, iron plate ［ 1 ］ is fastened on building and strides on the beam ［ 5 ］, and the two ends of cant beam ［ 3 ］ are welded on the side of two adjacent longerons ［ 2 ］.

Claims (1)
