Method and structure for improving pull rod of gate or trash rack

Abstract

The invention discloses a method and structure for improving a pull rod of a gate or a trash rack. According to the method, an upper pull rod section and a lower pull rod section which are connected with the gate or the trash rack are connected through a hinge pin perpendicular to the upper pull rod section and the lower pull rod section, so that the upper pull rod section and the lower pull rod section deflect in perpendicular directions, wherein one pull rod section deflects under the effect of an external factor such as displacement of a locking beam or vibration of the gate or the trash rack; and the other pull rod section connected with the deflected pull rod bears force in a direction perpendicular to the deflection direction, so that the friction force between the hinge pin and thepull rod is increased, the pull rod section is prevented from deflecting in the same direction, the influence of the deflection of the pull rod section on the deflection of the whole pull rod is greatly reduced, the accident that a fixing bolt is sheared off due to the large force borne by the hinge pin of the pull rod, and consequentially, the hinge pin is separated from the pull rod is prevented, and the operating safety of the pull rod is effectively improved.

Description

technical field [0001] The invention relates to an improvement method and structure of a gate and a trash rack tie rod, belonging to the technical field of metal structures of water conservancy and hydropower projects. Background technique [0002] For gates and trash rack tie rods, the connected upper and lower tie rods are generally connected by pins arranged in the same direction, and the deflection direction of all the tie rods is the same. There is a problem that one of the tie rods is affected by external factors such as the displacement of the locking beam, the gate Or the vibration of the trash rack deflects, and all the tie rods are deflected in one direction, which will cause a large amount of deflection of the overall tie rod, and sometimes cause part of the pin shaft to shear off the fixing bolt due to a large force, and the pin shaft will be detached from the tie rod. Accidents cause losses, and the difficulty of maintenance in the later stage is also relatively...

Problems solved by technology

[0002] For gates and trash rack tie rods, the connected upper and lower tie rods are generally connected by pins arranged in the same direction, and the deflection direction of all the tie rods is the same. There is a problem that one of the tie rods is affected by external factors such as the displacement of the locking beam, the gate Or the vibration of the trash rack deflects, and all the tie rods are deflected in one direction, which will cause a large amount of deflection of the overall tie rod, and sometimes cause part of the pin shaft to shear off the fixing bolt due to a large force, and the pin shaft will be detached from the tie rod. Accidents cause losses, and later maintenance is also difficult. Therefore, there are still deficiencies in the existing technology and need to be further improved.
