A door leaf structure of surface hole arc door

Abstract

The invention discloses a gate leaf structure of a spillway radial gate. The gate leaf structure of the spillway radial gate comprises an upper main cross beam and a lower main cross beam which are arranged on the inner side of a gate leaf, wherein lifting lug plates are arranged at the upper part of the lower main cross beam, short cross beams are arranged at the upper parts of the lifting lug plates, and single-web side beams are arranged at the upper parts of the short cross beams and connected with the upper main cross beam. The gate leaf structure is simple in structure, easy to manufacture, investment-saving and quite convenient to mount, and operation space for a mounting worker is large.

Description

technical field [0001] The invention relates to a door leaf structure of an arc door with a surface hole, belonging to the technical field of water conservancy and hydropower engineering gates. Background technique [0002] For the surface hole arc door, the door leaf usually adopts the structure type of double main beams, and the left and right ends of the double main beams of the door leaf are symmetrically arranged with double web box-shaped side beams, and the side beams are opened with hanging holes at the lower main beams and also serve as lifting lugs. , the hanging shaft adopts the type in which the shaft stop plate is fixed by bolts on the inner side; the partition plate is evenly arranged in the longitudinal direction, and the partition plate is set at the position corresponding to the center line of the support arm, and the gusset plate is set on the rear flange of the partition plate to connect with the tie beam of the support arm . The door leaf of this type of...

AI Technical Summary

Problems solved by technology

The door leaf of this type of gate has good integrity, but there are also the following main problems: ① The inner side of the side beam is close to the pier wall, and the operating space is narrow, so it is difficult to install the hanging shaft on the inner side, especially for arc gates with small openings ; ② The side beams between the double main beams are double webs and have rear flanges. To install side wheels, people need to go inside the box-shaped side beams, which is very inconvenient to install; The connecting beam can only be connected in the center, and the support arm is constrained by a single point in the middle, which is not conducive to the support arm's resistance to out-of-plane instability; so the existing technology is still not perfect
