Abstract
The invention discloses a web reinforcing device for a crane, comprising: an upper flange plate, a web, a flower flange plate, upper steel angles, connectors, two stiffeners and lower steel angles. The upper ends of the upper steel angles bend outward from the web, the lower ends of the upper steel angles are fixedly connected with the upper portion of the web through high-strength bolts, the upper ends of the two stiffeners bend outward from the web, the lower ends of the stiffeners are welded to the middle of the web, the upper and lower ends of the connectors all bend outward from the web, the lower ends of the connectors are fixedly connected with the upper ends of the stiffeners through bolts, the upper ends of the upper steel angles and the upper ends of the connectors are fixedly connected with the upper flange plate through high-strength bolts, the lower steel angles bend outward from the web, the upper ends of the lower steel angles are fixedly connected with the web through high-strength bolts, and the lower ends of the lower steel angles are fixedly connected with the lower flange plate through high-strength bolts. The web reinforcing device has the advantages of structural stability and long service life.
Description
Technical field
The present invention relates to a kind of crane web plate device, be applied to hoisting and hanging technical field.
Background technology
Crane is big, easy to operate due to its hoisting weight, is widely used in large-scale processing factory, and girder is as the critical piece of crane, and the quality of its structure directly affects work efficiency and the direct relation person safety of crane；Connect flange plate on girder web plate, under connect bottom wing listrium, be typically all by welding by the way of be attached, due to lifting workpiece heavier, the most after long-term use, it may appear that crackle, if the most just reinforcing, potential safety hazard easily occurs.
Summary of the invention
For solving the defect of prior art, the invention discloses a kind of crane web plate device, there is the advantage that stabilized structure, safety are high.
nullThe invention discloses a kind of crane web plate device，Including: top flange plate、Web、Bottom wing listrium、Upper angle steel、Connector、Reinforcement、Lower angle steel，Described top flange plate、Bottom wing listrium is respectively and fixedly connected to the two ends up and down of web，Described upper angle steel upper end deviates from web and is bent outwardly，The lower end of described upper angle steel is affixed with web top by high-strength bolt，Described reinforcement is two and its upper end deviates from web and is bent outwardly，The lower end of described reinforcement is welded on the middle part of web，The two ends up and down of described connector all deviate from web and are bent outwardly，Described connector lower end is affixed with reinforcement upper end by bolt，Described upper angle steel upper end、Connector upper end is affixed with top flange plate by high-strength bolt，Described lower angle steel lower end deviates from web and is bent outwardly，The upper end of described lower angle steel is affixed with web by high-strength bolt，Described lower angle steel lower end is affixed with bottom wing listrium by high-strength bolt.
It is symmetrical about web that described upper angle steel, lower angle steel, the quantity of connector are two and the upper angle steel of the left and right sides, lower angle steel, connector.
Owing to using technique scheme, the present invention has a following advantageous benefits:
1, stabilized structure；
2, during lifting, workpiece gravity will not act directly on web and top flange plate, bottom wing listrium weld, it is possible to life-time service, service life is long.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention a kind of crane web plate device.
Wherein: angle steel under 1-top flange plate, 2-web, 3-bottom wing listrium, the upper angle steel of 4-, 5-connector, 6-reinforcement, 7-.
Detailed description of the invention
nullAs shown in Figure 1，The invention discloses a kind of crane web plate device，Including: top flange plate 1、Web 2、Bottom wing listrium 3、Upper angle steel 4、Connector 5、Reinforcement 6、Lower angle steel 7，Described top flange plate 1、Bottom wing listrium 3 is respectively and fixedly connected to the two ends up and down of web 2，Described upper angle steel 4 upper end deviates from web 2 and is bent outwardly，The lower end of described upper angle steel 4 is affixed with web 2 top by high-strength bolt，Described reinforcement 6 is two and its upper end deviates from web 2 and is bent outwardly，6 lower ends of described reinforcement are welded on the middle part of web 2，The two ends up and down of described connector 5 all deviate from web 2 and are bent outwardly，Described connector 5 lower end is affixed with reinforcement 6 upper end by bolt，Described upper angle steel 4 upper end、Connector 5 upper end is affixed with top flange plate 1 by high-strength bolt，Described lower angle steel 7 lower end deviates from web 2 and is bent outwardly，The upper end of described lower angle steel 7 is affixed with web 2 by high-strength bolt，Described lower angle steel 7 lower end is affixed with bottom wing listrium 3 by high-strength bolt.
It is symmetrical about web 2 that described upper angle steel 4, lower angle steel 7, the quantity of connector 5 are two and the upper angle steel 4 of the left and right sides, lower angle steel 7, connector 5.
The present invention is implemented: wrapped up with top flange plate 1, bottom wing listrium 3 welded seam by web 2 by upper angle steel 4, lower angle steel 7, the active force that during lifting, gravity brings will not act directly on weld seam, and connect a reinforcement 6 by connector 5 on the top flange plate 1 that stress is most, even if the time of use is long, the impact brought also is that the high-strength bolt of each junction produces loosening, as long as making regular check on, significantly avoiding the generation of accident, safety is high and physical life is long.
Last it is noted that above example only in order to the present invention is described and and unrestricted technical scheme described in the invention；Therefore, although this specification with reference to each above-mentioned embodiment to present invention has been detailed description, but, it will be understood by those within the art that, still the present invention can be modified or equivalent；And all are without departing from the technical scheme of the spirit and scope of the present invention and improvement thereof, it all should be contained in scope of the presently claimed invention.
