Abstract

The utility model relates to a multi-function crane for construction. A fixed upper rotating tower crane and a steel cable elevator with a hanging cage are organically combined into a whole body. The utility model is characterized in that two guiding rails of the hanging cage of the elevator are connected with the tower body of the tower crane; two main chords of the tower body are also used as the other two guiding rails of the hanging cage of the elevator; the hoist of the elevator is connected with the cage through a pulley block on a suspension rack installed on the top of the tower body. The tower crane and the elevator can work independently and respectively and can also work simultaneously; The utility model improves the work efficiency of construction, and is suitable for construction in narrow zones and in middle and lower buildings.

Description

Multi-function crane for construction

Multi-use architecture elevator machinery provided by the utility model can be used for building ground vertical-lift material and lifting components, belongs to the elevator machinery field.

At present, building operation is widespread use tower crane lifting components all, compare with derrick elevator lifting material with previously used door frame elevator, improved operating efficiency greatly, alleviated labour intensity, still, need use elevator when promoting the accessory appliances of material in the interior decoration operation, often to be equipped with a jacking system in addition, not only increase equipment but also taken the operation place.

The purpose of this utility model organically is combined into one fixed type high-level slewing tower crane and steel wire rope type cage elevator exactly, but both all independently workings are independent of each other.

Accompanying drawing 1 and accompanying drawing 2 are the utility model multi-use architecture elevator machinery structural representation, wherein ［ 1 ］-fixed type high-level slewing tower crane, ［ 2 ］-body of the tower, ［ 3 ］-elevator load overload restraint device, ［ 4 ］-elevator winch, ［ 5 ］-elevator craning cage, ［ 6 ］-haulage cable, ［ 7 ］-suspension holdfast, ［ 8 ］-cage roller, ［ 9 ］-body of the tower main chord, ［ 10 ］-guide rail.

Existing accompanying drawings is as follows: suspension holdfast ［ 7 ］ links to each other with body of the tower ［ 2 ］ top, and wherein two guide rails ［ 10 ］ of elevator craning cage ［ 5 ］ link to each other with body of the tower ［ 2 ］. Lift hoist engine ［ 4 ］ links to each other with elevator craning cage ［ 5 ］ by the assembly pulley on the suspension holdfast ［ 7 ］. Fixed high-level slewing tower crane ［ 1 ］ then is entirely the tower machine of a platform independent job, and cage elevator ［ 5 ］ also can work independently, and both mutually noninterferes all can be worked respectively or simultaneously.

Adopt the utility model both to improve the building operation operating efficiency, alleviated labour intensity, accelerated job schedule, and saved building operation operation place.Its advantage is particularly outstanding in the median low structure construction site.In addition, its specified hoisting moment of the utility model is between 50～120KNm, and cage elevator nominal payload is between 0.5t, having technology makes simple, lower, the small investment of cost is manufactured experimently distinguishing features such as fast and safe and reliable, is particularly suitable for small and medium construction machine works and produces.

Its principle of work of the utility model is: tower machine ［ 1 ］ have hoist, function such as revolution, luffing, and cage elevator ［ 5 ］ depends on the body of the tower ［ 2 ］ of tower machine ［ 1 ］, and in addition two guide rails of elevator craning cage ［ 5 ］ are promptly by main chord ［ 9 ］ double as of body of the tower ［ 2 ］.Elevator craning cage ［ 5 ］ relies on the main chord ［ 9 ］ of two guide rails ［ 10 ］ and two double as guide rails to carry out oscilaltion lifting material under steel rope ［ 6 ］ traction of winch ［ 4 ］.

Claims

1, a kind of multi-use architecture elevator machinery, it is made up of fixed type high-level slewing tower crane [1], body of the tower [2], elevator craning cage [5], guide rail [10] etc., it is characterized in that:
