Description

Technical Field

[0001] The utility model relates to the technical field of bridge pier crack maintenance, in particular to a crack maintenance device for bridge piers. Background Art

[0002] Bridge piers are the intermediate supporting structures of bridges with two or more spans, except for the abutments at both ends that connect with the embankment. Bridge piers are mainly composed of top caps and pier bodies. Bridge piers are divided into solid piers, columnar piers and frame piers. According to their plane shapes, they can be divided into rectangular piers, pointed piers, circular piers, etc. The materials for building bridge piers can be wood, stone, concrete, steel, etc.

[0003] It is inevitable that cracks will appear on bridge piers after long-term use. Therefore, it is necessary to regularly detect and maintain the cracks on the piers. In the process of maintaining the cracks on the piers, it is often necessary to use a glue injection machine to fill and maintain the cracks on the piers. However, the glue injection machines commonly used on the market often do not have a material guiding structure, and cannot guide the filling materials added to the feed port of the glue injection machine. The filling materials entering the feed port of the glue injection machine may be blocked and affect the normal progress of the maintenance work. It is necessary to manually clear the blockage, which is time-consuming and labor-intensive. In view of this, we propose a crack maintenance device for bridge piers. Utility Model Content

[0027] The material guiding mechanism 5 is arranged on the top surface of the working plate 1 and is used for guiding the materials entering the feeding funnel 3. The material guiding mechanism 5 includes an L-shaped vertical plate 51 fixed on the top surface of the working plate 1 near the rear end, a roller 52 rotatably connected between the horizontal plate end of the vertical plate 51 and the working plate 1, a cylindrical cam 53 coaxially fixed on the circumferential outer wall of the roller 52, a moving block 54 slidably connected to the right side surface of the vertical plate end of the vertical plate 51, a rotating rod 512 coaxially fixed on the top surface of the roller 52, a lifting motor 514 installed on the top surface of the vertical plate 51 and used to drive the rotating rod 512 to rotate, a moving rod 57 fixed on the front side surface of the moving block 54, a mounting plate 58 fixed on the front side surface of the moving rod 57, and a rotating column 59 rotatably connected to the mounting plate 58. The rod body is installed on the bottom surface of the rotating column 59 and is used for the auger 510 of the material guiding operation, and the rotating motor 511 is installed on the top surface of the mounting plate 58 and the output shaft is coaxially connected with the rotating column 59. The circumferential outer wall of the cylindrical cam 53 is provided with a spiral slide groove, and the right side surface of the moving block 54 is fixed with a slide column 55 which is slidably connected to the slide groove on the outer wall of the cylindrical cam 53. By arranging the working plate 1, the glue injection machine body 2 and the feeding funnel 3, the cracks of the bridge piers can be maintained.

[0028] In this embodiment, the material guiding mechanism 5 also includes two gears 513 located above the vertical plate 51 and meshing with each other, and a rotating shaft 515 coaxially connected to the output shaft of the lifting motor 514, and the two gears 513 are coaxially fixed on the circumferential outer walls of the rotating shaft 515 and the rotating rod 512, respectively, which can smoothly drive the two gears 513 to rotate, and then indirectly drive the cylindrical cam 53 to rotate.

[0029] In addition, a guide groove is provided on the right side surface of the vertical plate end of the vertical plate 51, and a guide block 56 is fixed on the left side surface of the moving block 54, which is slidably connected to the guide groove on the right side surface of the vertical plate end of the vertical plate 51, so as to guide the movement of the moving block 54, and further indirectly guide the movement of the rotating column 59 and the auger 510.

[0030] Furthermore, the positions of the rotating column 59 and the auger 510 correspond to the positions of the feed funnel 3, and the sizes of the rotating column 59 and the auger 510 are compatible with the size of the feed funnel 3, so that the rotating column 59 and the auger 510 can smoothly enter the interior of the feed funnel 3 and perform the material guiding work.
