Abstract
The utility model relates to a section steel, that is, a special-purpose portal frame section steel for forklift. The utility model is characterized in that an obtrusive chimb parallel to one side is arranged near one side of the lateral side at the bottom of channel steel. Convex bumps are arranged on the transitional circular bead of the inner and outer bottoms of the channel steel. The utility model increases the rigidity of the section steel and improves the bearing capacity of the portal frame; in addition, the utility model is beneficial for the guide of a roller. The design of the convex bumps on the transitional circular bead of the inner and outer bottoms of the channel steel reduces work processes and improves work efficiency without a welding process.
Description
Technical field
The utility model relates to a kind of shaped steel, specifically fork truck special utility gantry-shaped steel.
Background technology
Channel-section steel and homemade J type structural steel that the special-purpose door frame of fork truck adopts are at present made, and J type structural steel welds on existing channel-section steel basis and makes, and the poor structure rigidity of door frame is unfavorable for the carrying of door frame, is unfavorable for the guiding of roller on the other hand.
Summary of the invention
In order to improve the structural rigidity of door frame, and be beneficial to the roller guiding, the utility model provides a kind of fork truck special utility gantry-shaped steel.
Its structural development scheme is:
Fork truck special utility gantry-shaped steel comprises channel-section steel, it is characterized in that:
A, channel-section steel outside bottom surface, a nearly side side edge are provided with the overhanging chimb parallel with side;
The excessive fillet of B, chimb and outside bottom surface place is provided with projection;
C, with excessive fillet place, the cooresponding inboard of chimb be provided with projection.
Described projection is for to exceed the bottom surface by 1/4th places, adjacent bottom surface are smooth, and the smooth excessive fillet place that excessively arrives.
The structure design of the utility model shaped steel has increased structural rigidity, has improved the load-carrying capacity of door frame, helps the guiding of roller simultaneously.The projection design at inside and outside excessive fillet place does not need to finish by welding sequence, has reduced operation, has improved work efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Embodiment:
This fork truck special utility gantry-shaped steel comprises channel-section steel 1, is fixed with the overhanging chimb 2 parallel with side in channel-section steel 1 outside bottom surface, a nearly side side edge; Chimb 2 has projection 3 with the excessive fillet of outside bottom surface place; There is projection 3 at excessive fillet place with the cooresponding inboard of chimb.
Claims (2)
