Abstract
The utility model discloses an english truss girder of hoist, including an upper chord, two parallel arrangement's lower chord and the english truss structural formula web member of connecting upper chord and lower chord, the square steel welds in upper chord upper surface middle part on the length direction of upper chord, two parallel arrangement's lower chord passes through the channel -section steel and connects, upper chord and lower chord are manufactured by H shaped steel and are formed, english truss structural formula web member is formed by the rectangular pipe preparation, this equipment structure is novel, therefore, the clothes hanger is strong in practicability, in the use front face area little and the dead weight lighter, simple manufacture in process of production, and lower cost.
Description
Technical field
This utility model relates to crane field, the truss girder of a kind of crane.
Background technology
Existing single-beam door main beam is according to truss structure, when large-tonnage object need to be lifted, the web ratio hanging I-steel used for electric hoist is relatively thin, use requirement can not be met, if girder to be changed into box structure, then the door machine at outdoor use in use has that front face area is big and deadweight is bigger, causing door machine, to consume material in process of production more, make the cost of manufacture in production process higher, be therefore badly in need of the crane girder that a kind of in use front face area is little and deadweight is lighter.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of novel structure, practical, and in use front face area is little and deadweight is relatively light, makes simple in process of production, the English truss girder of lower-cost crane.
This utility model adopts the following technical scheme that for solving above-mentioned technical problem, a kind of English truss girder of crane, it is characterized in that: include a top boom, two lower booms be arrangeding in parallel and connect the triangular truss structure formula web member of top boom and lower boom, square steel is welded in top boom upper surface middle part along the length direction of top boom, two lower booms be arrangeding in parallel are connected by channel-section steel, and top boom and lower boom are manufactured by H profile steel and formed.
It is further preferred that described triangular truss structure formula web member is made by rectangular tube.
This device structure is novel, practical, and in use front face area is little and deadweight is relatively light, makes simple in process of production, and cost is relatively low.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model；
Fig. 2 is side view of the present utility model.
Drawing illustrates: 1, top boom, 2, lower boom, 3, triangular truss structure formula web member, 4, square steel, 5, channel-section steel, 6, H profile steel, 7, rectangular tube.
Detailed description of the invention
Particular content of the present utility model is described in detail in conjunction with accompanying drawing.The English truss girder of crane, including 1, two lower booms be arrangeding in parallel 2 of a top boom and the triangular truss structure formula web member 3 that connects top boom 1 and lower boom 2, square steel 4 is welded in top boom 1 upper surface middle part along the length direction of top boom 1, square steel 4 is welded on H profile steel top boom 1, can be as a part for top boom 1, not only from heavy and light and enhance bearing capacity；Two lower booms be arrangeding in parallel 2 are connected by channel-section steel 5, top boom 1 and lower boom 2 are manufactured by H profile steel 6 and are formed, ensure that in process of production substantially without welding, reducing welding stress deformation and because welding quality does not passes a test the quality problems caused, described triangular truss structure formula web member 3 is made by rectangular tube 7, decreases the workload of welding production, and rectangular tube 7 easily purchases, stock is simple, and finished product is bought intercepting and just can be used, and facilitates and manufactures.
Of the present utility model ultimate principle has more than been shown and described; principal character and advantage; on the premise of without departing from this utility model spirit and scope, this utility model also has various changes and modifications, and these changes and improvements both fall within claimed scope of the present utility model.
