Abstract
The utility model discloses a reinforcing plate of a square-tube-shaped standard section main chord. A block of reinforcing plate is welded to a diagonal position inside the end of a square tube of the standard section main chord. The reinforcing plate of the square-tube-shaped standard section main chord has the advantages that the V-shaped reinforcing plate is welded to the diagonal position of the end of the square tube of the standard section main chord, stress concentration at the positions of a connecting sleeve and the main cord can be effectively reduced, cracks of the main chord in a use process are avoided, and service life and safety of a tower crane are guaranteed.
Description
Technical field
The utility model relates to a kind of square tube shape standard knot main chord brace panel.
Background technology
The adapter sleeve position of square tube shape tower machine standard knot main chord is the main force part of tower machine; Very easily crack in the not enough situation lower joint sleeve of permanent load bolt pretightening and main chord junction even rupture, untimely discovery is handled serious accident can be taken place.
Summary of the invention
The purpose of the utility model is for overcoming the deficiency of above-mentioned prior art, a kind of square tube shape standard knot main chord brace panel being provided.
For realizing above-mentioned purpose, the utility model adopts following technical proposals:
A kind of square tube shape standard knot main chord brace panel, the brace panel of in-to-in diagonal positions welding in standard knot main chord square tube end.
The upside of said brace panel is provided with the opening of V-arrangement.The V-arrangement opening can slow down brace panel and main chord place stress concentration.
The lower end of the downside of brace panel and main chord square tube is approaching, and upside is positioned on main chord square tube and the adapter sleeve junction.Said " on " D score all is as the criterion with the orientation up and down under the standard knot main chord normal operating condition.
The beneficial effect of the utility model is; One of diagonal positions welding has the vee-type brace panel in standard knot main chord square tube end; Can effectively reduce adapter sleeve and main chord place stress concentration, avoid that crackle appears in main chord in the process of using, guarantee the service life and the safety of tower machine.
Description of drawings
Fig. 1 is the right elevation of Fig. 2;
Fig. 2 is the utility model structural representation;
Wherein 1. brace panels, 2. adapter sleeve, 3. main chord.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Like Fig. 1, shown in Figure 2, a kind of square tube shape standard knot main chord brace panel 1, brace panel 1 of in-to-in diagonal positions welding in standard knot main chord 3 square tube ends.
Brace panel 1 connects the diagonal positions at square tube and place, adapter sleeve 2 junctions, and the downside of brace panel 1 flushes with the lower end of main chord 3 square tubes, and the upside of said brace panel 1 is provided with the opening of V-arrangement, and upside is positioned on main chord 3 square tubes and adapter sleeve 2 junctions.Such scheme all is in order to reduce adapter sleeve 2 and main chord 3 place's stress concentration.
Have vee-type brace panel 1 one of standard knot main chord 3 square tube end diagonal positions welding, can effectively reduce adapter sleeve 2 and main chord 3 place's stress concentration, avoid that crackle appears in main chord 3 in the process of using, guaranteed the service life and the safety of tower machine.
