Device for water-carrying grinding-in of grinding core and grinding cover of spherical hinge used in bridge rotation construction

Abstract

The invention relates to a device for water-carrying grinding-in of a grinding core and a grinding cover of a spherical hinge used in bridge rotation construction. The device comprises a gantry crane assembly used for lifting the grinding cover, and a winch assembly used for pulling the grinding cover to rotate so as to ensure that the grinding cover and the grinding core are ground in, wherein a water basin is formed around the grinding core and the grinding cover; a water inlet pipe is vertically arranged in the center of the grinding cover; the upper end of the water inlet pipe is connected with a water tank, and the lower end of the water inlet pipe is connected with a shaft sleeve which is arranged inside the grinding cover and is positioned above a positioning shaft of the grinding core; a water outlet pipe is arranged on one side of the water basin; a water storage basin communicated with the water outlet pipe can be also arranged at one end of a water outlet of the water outlet pipe; and a water pump which is arranged above the water storage basin is communicated with the water tank by a water injection pipe. After the grinding core and the grinding cover of the spherical hinge are ground in with water by the device, the contact part between the grinding core and the grinding cover are extremely smooth, and the friction between the grinding core and the grinding cover during rotation is small; when bridges are rotated, the jacking force during the rotation of the spherical hinge is small, and the bridges are easily rotated; the height difference of a joint between the rotated bridges is small, and the quality of the bridge rotation construction is high; and the efficiency of the water-carrying grinding-in is high, and the used water can be recycled so as to save water.

Description

technical field [0001] The invention relates to a device for processing parts used in bridge swivel construction, especially a device for grinding the grinding center and the grinding cover of a spherical joint with water. Background technique [0002] Spherical hinge is a main component used in bridge swivel construction, which includes two parts: grinding center and grinding cover made of concrete. Before using the ball hinge, the grinding center and the grinding cover must be run-in. The existing running-in device can only dry the grinding center and the grinding cover. The problem is that the contact part between the grinding center and the grinding cover after dry grinding The smoothness of the bridge is not enough, the friction force between the grinding center and the grinding cover is large, when the bridge rotates, the top thrust of the ball hinge rotation is large, the bridge is difficult to rotate, and the closing of the bridge after the bridge rotates is easy to ...

Before using the ball hinge, the grinding center and the grinding cover must be run-in. The existing running-in device can only dry the grinding center and the grinding cover. The problem is that the contact part between the grinding center and the grinding cover after dry grinding The smoothness of the bridge is not enough, the friction force between the grinding center and the grinding cover is large, when the bridge rotates, the top thrust of the ball hinge rotation is large, the bridge is difficult to rotate, and the closing of the bridge after the bridge rotates is easy to occur. The difference in height directly affects the quality of bridge swivel construction
