Abstract
The utility model discloses a bridge crane which comprises two girders and a hoisting mechanism installed on a roadster. The middle of the lower part of each girder is respectively locked with an I-shaped steel track, the front and the rear as well as the left and the right four pulley blocks are installed in slots at the two sides of each I-shaped steel track by the way that the front is symmetric to the rear and the left is symmetric to the right, and the four corners of the roadster are respectively hung on the shell bodies of the four pulley blocks by pin rolls and steel ropes. The upper parts of the two girders are fixed with strengthening ribs. The bridge crane hangs the hoisting mechanism between the girders to effectively utilize the roof space and increase the compressive strength, the structure is simple, the cost is low, and the range of application is wide.
Description
Technical field:
The utility model relates to lifting, and particularly a kind of to take roof space little, the crane in bridge type that compressive strength is big.
Background technology:
Present crane in bridge type, be that parallel symmetry is connected and fixed two girders between two beam heads, fix an I-beam section track with pressing plate at each respectively above the girder, on the I-beam section track, a sport car is installed, lifting mechanism is installed on the sport car with the assembly pulley assembly is parallel.The defective that the installation form of this inhead type sport car exists is that to take roof space big.
Summary of the invention:
The purpose of this utility model provides a kind of simple in structure, takies the little crane in bridge type of roof space.
Technical solution of the present utility model is finished as follows, it includes two girders and the lifting mechanism that is installed on the sport car, it is characterized in that: fixing respectively in the middle of each girder bottom has an I-beam section track, be symmetrically installed with four assembly pulleys all around in each I-beam section track two side channel, hang on four assembly pulley housings with bearing pin and cable wire respectively for four jiaos of sport car.Be fixed with reinforced rib on two girder tops.
The utility model is hung lifting mechanism and effectively utilized roof space between girder, has increased compressive strength, and simple in structure, cost is low, wide accommodation.
Description of drawings:
Fig. 1 is a plan structure scheme drawing of the present utility model,
Fig. 2 is a side-looking structural representation of the present utility model.
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing: the utility model includes two girders 1, with the lifting mechanism 4 that is installed on the sport car, its improvements are that two I-beam section tracks 6 are fixed respectively in the draw-in groove of two girder 2 bottoms, be symmetrically installed with four assembly pulleys all around in each I-beam section track two side channel, hang on four assembly pulley housings 5 with bearing pin and cable wire respectively at four angles of runing frame 3, and the lifting mechanism of installing on the sport car is between two girders.In order further to increase the compressive strength of girder and the horizontal stability of car load, be fixedly connected with reinforced rib on two girder tops.This structure increases the compressive strength of girder, and has reduced the height of car load.
