Abstract
The invention relates to a tower crane, which is characterized in that wind shields (1) are fixed on web members (6) inside a crane jib (2) by U-shaped bolt connection pairs (5); steel skeletons (4) are arranged below the wind shields (1); the windward area of the crane jib (2) of the wind shields (1) is larger than that of a balance boom (3); on each web member (6), the wind shields (1) are equipped with drill holes to be connected with the crane jib (2); each U-shaped bolt connection pair (5) is formed by connecting a U-shaped bolt (7), a nut (8), an elastic washer (9), and a flat gasket (10); and the U-shaped bolts (7) and the flat gaskets (10) fit with the drill holes on the wind shields (1). The beneficial effects of the invention are as follows: the tower crane has a simple structure and is easy to manufacture; and when wind speed is high, the tower crane is not easy to collapse and the crane jib is not easily broken.
Description
Technical field
The present invention relates to a kind of tower crane.
Background technology
Consider to receive the wind-force factor affecting, tower crane requires the equilibrium arm wind area should be not less than the crane arm wind area when design.But according to its actual conditions, the crane arm installation length may be less than design length during owing to installation, and its wind area also reduces immediately.When the tower crane that shortens boom length is installed, when it received windage, crane arm can not be rocked to downwind with the wind, caused whole tower crane topside wind area to increase, and windage increases; Crane arm also receives windage.When wind speed is big, very easily causes tower crane and topple and collapse and safety misadventures such as crane arm fractures.
Summary of the invention
The purpose of this invention is to provide a kind of tower crane.
The technical scheme that the present invention is taked for its technical matters of solution is:
A kind of tower crane is characterized in that: the U-bolt auxiliary connection is fixed on air baffle on the web member in the crane arm.
Steel frame is laid in described air baffle below.
The wind area of the crane arm of described air baffle is greater than the equilibrium arm wind area, every web member place, and the air baffle drilling links to each other with crane arm.
Described U-bolt auxiliary connection is connected into by U-bolt, nut, bullet packing ring, flat shim, and boring is mated each other on U-bolt, flat shim and the air baffle.
The invention has the beneficial effects as follows: simple in structure, be easy to make, when wind speed is big, is difficult for causing tower crane and topples and collapse and crane arm fractures.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Fig. 1 is a constructional drawing of the present invention;
Fig. 2 is a reinforcement steel frame scheme drawing of the present invention;

Fig. 4 is a U-bolt auxiliary connection scheme drawing of the present invention.
Among the figure: 1. air baffle, 2. crane arm, 3. equilibrium arm, 4. steel frame, 5.U type bolted connection is secondary, 6. web member, 7.U type bolt, 8. nut 9. plays packing ring, 10. flat shim.
The specific embodiment
A kind of tower crane is characterized in that: U-bolt auxiliary connection 5 is fixed on air baffle 1 on the web member 6 in the crane arm 2.
The wind area of the crane arm 2 of described air baffle 1 is greater than equilibrium arm 3 wind areas, every web member 6 places, and air baffle 1 drilling links to each other with crane arm 2.
Described U-bolt auxiliary connection 5 is connected into by U-bolt 7, nut 8, bullet packing ring 9, flat shim 10, and boring is mated each other on U-bolt 7, flat shim 10 and the air baffle 1.
Claims (4)
