Problems solved by technology

There are two forms of traditional arc-shaped gate support arms: two-arm and three-arm. Although the former is simple in manufacturing and processing and has higher stability under the same amount of materials, the overall size of the gate is large and the rigidity is poor; the latter improves the overall rigidity. , but due to the scattered use of materials for the arms, the stability of the structure is low, and the proportion of accidents is also large

Embodiment Construction

[0011] Such as figure 1 As shown, the embodiment of the present invention provides a bifurcated tree-shaped arc door support arm, which is installed and fixed on the arc door 3, and includes a trunk arm 1 and two branch arms 2, and one end of the two branch arms 2 is respectively Connected to one end of the trunk arm 1, the other end of the trunk arm 1 is connected to the hinge of the arc door 3, and the other ends of the two branch arms 2 are respectively fixed on the main longitudinal beam of the arc door 3.

[0012] Preferably, the trunk arm 1 and the branch arm 2 are rectangular parallelepiped and made of Q345B steel.

[0013] As a further preference, such as figure 2 As shown, after the positions of points O, A and B are determined, point O is the hinge point of the arc gate, and points A and B are arranged according to the medium load of "Code for Design of Steel Gates in Water Conservancy and Hydropower Engineering (SL74-2013)" The connection point between the determ...

Abstract

The invention discloses a two-forked tree-shaped arc door supporting arm installed on an arc door. The two-forked tree-shaped arc door supporting arm comprises a trunk arm and two branch arms. One end of each of the two branch arms is connected to one end of the trunk arm, the other end of the trunk arm is connected to a supporting hinge of the arc door, and the other end of each of the two branch arms is fixed to a main longitudinal beam of the arc door. By adoption of the technical scheme, the problem of contradiction of high stiffness, high stability and lightness of the large arc door is solved.

Description

technical field [0001] The invention belongs to the technical field of support arm structures, and in particular relates to a bifurcated tree-shaped arc gate support arm. Background technique [0002] The gate arm is mainly used to bear the water load generated by the arc gate panel, and is installed on the overflow dam section. There are two forms of traditional arc-shaped gate support arms: two-arm and three-arm. Although the former is simple in manufacturing and processing and has higher stability under the same amount of materials, the overall size of the gate is large and the rigidity is poor; the latter improves the overall rigidity. , but due to the scattered use of materials for the arms, the stability of the structure is low, and the proportion of accidents is also large. Contents of the invention [0003] The problem to be solved by the present invention is to provide a bifurcated tree-shaped arc door support arm to solve the contradictory problems of high rigid...
