[0002] Bridge expansion joint: refers to a device installed between two beam ends, between a beam end and an abutment, or at the hinge position of a bridge to meet the requirements of bridge deck deformation. The expansion joint should be able to freely expand and contract in two directions parallel and perpendicular to the bridge axis, be firm and reliable, and ensure smooth vehicle passage without sudden jumps or noises. It should also prevent rainwater, garbage, and soil from seeping in and blocking. Installation, inspection, maintenance, and cleaning should be simple and convenient. The function of the bridge expansion joint is to adjust the displacement and connection between the superstructure caused by vehicle loads and bridge building materials. In the repair work of bridge expansion joints, a premixed mortar material is involved. This material is specifically designed to meet the needs of rapid repair of bridge expansion joints.

A fixed rotating rod 9 is fixedly installed at the other end of the coupling 8. A plurality of stirring frames 10 are circumferentially and equally spaced on the side surface of the fixed rotating rod 9.
[0023] Square notches 11 are opened on the surface of the stirring frame 10. A plurality of layers of stirring racks 12 are arranged on the inner side surface of the stirring frame 10 from top to bottom. The stirring rack 12 at the lowermost layer position of the stirring frame 10 is distributed in a mirror-image opposition to the upper stirring rack 12. A plurality of auxiliary brackets 13 are installed at the joints of the two stirring frames 10 from top to bottom. The auxiliary bracket 13 at the lowermost layer position is symmetrically distributed in a mirror image to the upper auxiliary bracket 13. An inclined surface 14 is opened on the outer side of the stirring frame 10. An arc-shaped side plate 15 is fixedly installed at one end of the stirring frame 10.
[0024] The outer curvature of the arc-shaped side plate 15 is consistent with the inner curvature of the mixing drum 1, and the side surface of the arc-shaped side plate 15 is in sliding contact with the inner wall surface of the mixing drum 1. The whole stirring frame 10 is made of a certain alloy material, and a layer of anti-corrosion coating is evenly coated on the surface of the stirring frame 10. The stirring racks 12 and the auxiliary brackets 13 as a whole present a hook-shaped special-shaped structure, and the maximum length value of the stirring racks 12 and the auxiliary brackets 13 is less than the length of the square notch 11.

One side of the guiding inclined surface 16 is seamlessly connected to one end of the inclined surface 14, and an obtuse angle is formed between them.
[0026] The implementation manner is specifically as follows: One side of the guiding inclined surface 16 is seamlessly connected to one end of the inclined surface 14, and an obtuse angle is formed between the two, so that the arc-shaped side plate 15 scrapes the mortar material on the wall of the mixing drum 1 through its own guiding inclined surface 16, and transfers the material to the inclined surface 14 on the outermost side of the mixing frame 10 through the guiding inclined surface 16.

Subsequently, the driving motor 6 drives the driving rotating shaft 7 and the fixed rotating rod 9 below it to rotate synchronously. Then, the fixed rotating rod 9 drives a plurality of mixing frames 10 arranged on its surface to rotate. Then, the side surface of the arc-shaped side plate 15 is in sliding contact with the inner wall surface of the mixing drum 1, so that the arc-shaped side plate 15 scrapes the mortar material on the wall of the mixing drum 1 through itself, and transfers the material to the inclined surface 14 on the outermost side of the mixing frame 10 through the guiding inclined surface 16 arranged on its side surface. At this time, the mortar material is introduced into the innermost side of the mixing frame 10, that is, the area where the mixing rack 12 and the auxiliary support 13 are located as a whole, and the mixing rack 12 and the auxiliary support 13 fully stir the guided mortar material to ensure the mixing effect of the overall device and the mixing uniformity of the mortar material. At the same time, by the two-way arrangement of the inclined surface 14 and the guiding inclined surface 16, it can meet the requirements of clockwise rotation and counterclockwise rotation in actual situations, further meeting the actual situations and conditions. Finally, the device completes the full mixing and stirring work of the mortar material, and that's it.
[0030] Step 3: First, the operator normally shuts down the device. Then, the operator checks whether the fixation between each component of the device is normal, and then replaces and repairs the aging and severely worn parts inside the device.
