Wear simulation test bench for the friction pair of the bottom pivot of the miter gate

Abstract

The invention relates to a wear simulation test bed for the bottom pintle friction pair of a miter gate. A vertical frame is installed on a base. A door frame is arranged on the side face of the vertical frame. The bottom end of the door frame is fixed on the base. A gate body is hinged to the vertical frame. The outer end face of the gate body is in contact fit with the door frame through a checkblock. One side of the gate body is provided with a gate hoist for opening and closing the miter gate. The other side of the gate body is provided with a damping device. The top of the gate body is provided with a suspension device which synchronously rotates with the gate body. The suspension device is arranged right above the gate body. A loading device is installed between the suspension device and the gate body. The top of the gate body is hinged to the rotating shaft. The top of the rotating shaft is in rotating fit with a top pintle installed on the gate body. The bottom of the gate body is supported on a bottom pintle through a bottom pintle support. By means of the test bed, the influences of different loads of the miter gate, different speeds of the miter gate, different lubricating modes of the miter gate and different materials of the bottom pintle friction pair on the frictional wear of the bottom pintle can be simulated.

Description

technical field [0001] The invention is a simulation test bench, which is a wear simulation test bench for the bottom pivot friction pair of a miter gate used in the field of water conservancy engineering, and belongs to the field of gate performance test equipment. Background technique [0002] With the development of China's inland shipping, miter gates are increasingly adopted by ship lock designers as a reliable gate type. In recent years, the traffic volume of ship locks has been increasing, and the number of gate openings has become more and more frequent, often exceeding the design volume of gate opening. Due to the increase in the number of openings, the wear of the bottom hinge of the miter gate is intensified, resulting in the lock of the bottom hinge of the gate, the tilt of the door body, and the lax closing of the gate, which has a bad influence on the normal operation of the ship lock. Moreover, the bottom hinge of the gate is under water all the year round. O...

Problems solved by technology

Due to the increase in the number of openings, the wear of the bottom hinge of the miter gate is intensified, resulting in the lock of the bottom hinge of the gate, the tilt of the door body, and the lax closing of the gate, which has a bad influence on the normal operation of the ship lock.

Moreover, the bottom hinge of the gate is under water all the year round. Once it is overhauled, the process is difficult and time-consuming.
