A method and connection structure for ensuring the normal operation of a flat fixed-wheel steel gate

Abstract

The invention discloses a method and a connection structure for ensuring normal running of a plain steel gate with fixed-wheels According to the method, an existing eccentric shaft adjustment device is refitted into a telescopic automatic adjustment device, and under the condition that a door body and a rail structure deform and water flow generates vibration impact on the gate, treads of the wheels can make good contact with rails all the time by means of automatic telescopic adjustment of the telescopic automatic adjustment device, the non-uniform stress phenomena of gaps, blockage and impact are prevented, and the normal running of the gate is ensured. By means of the method and the structure, the non-uniform bearing phenomena caused to fixed wheel contact positions when vibration impact is caused by deformation of the door body, the rails and other structures and the water flow can be effectively eliminated, damage to the gate and the rails caused by non-uniform bearing is prevented, and the running reliability of the gate is improved. Meanwhile, the accuracy requirement during manufacture and installation of the gate and the rails can be lowered, cost can be saved, good economic benefits and social benefits are achieved, and the method and the structure can be popularized in the field of design of the plain steel gate.

Description

technical field [0001] The invention relates to a method and a connection structure for ensuring the normal operation of a flat fixed-wheel steel gate, belonging to the technical field of gate operation in water conservancy and hydropower projects. Background technique [0002] At present, most of the flat steel gates using the fixed wheel as the main support device use an eccentric shaft as the adjustment device. When the gate is installed, the tread height of the wheel is adjusted according to the installation situation of the track to make it fully contact with the track. Secure the wheels after adjustment. When the gate is used for a certain period of time, due to many factors such as water pressure, shrinkage, and machining accuracy, the gate body and track will be deformed to varying degrees, causing gaps or jams at the contact between some fixed wheels and the track, causing The uneven load on the gate and the track will not only damage the fixed wheel or gate struct...

Problems solved by technology

[0003] The purpose of the present invention is to provide a method and connection structure to ensure the normal operation of the flat fixed-wheel steel gate, so as to prevent deformation of the gate body, track, etc. and water flow When the gate vibrates and impacts, the self-telescopic adjustment of the fixed wheel device can be used to maintain good contact between the wheel tread and the track, improve the force on the gate and the track, prevent gaps, jams, impacts and other uneven forces, and ensure the gate normal operation, thereby overcoming the deficiencies of existing technologies
