DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] Next, the technical solutions in the embodiments of the present utility model will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0018] Please refer to Figure 1 , Figure 2 , Figure 3 andFigure 4 The present utility model provides a technical solution: a finishing device for bridge deck concrete, including a fixing rod 1. The fixing rod 1 is L-shaped and is used for the hand to grip during the finishing operation. The side wall of the fixing rod 1 is integrally formed with a first gripping portion 2 and a second gripping portion 3. The arrangement of the first gripping portion 2 and the second gripping portion 3 facilitates the gripping operation of the fixing rod 1. During the operation, gripping the first gripping portion 2 and the second gripping portion 3 with both hands can make the holding of the fixing rod 1 more stable;
[0019] The side walls of the first gripping portion 2 and the second gripping portion 3 are evenly provided with anti-slip lines 4. By setting the anti-slip lines 4, the friction between the first gripping portion 2 and the second gripping portion 3 and the hand is further increased, strengthening the gripping stability of the hand on the fixing rod 1.
[0020] An installation frame 5 is welded and fixed at the end of the fixing rod 1. An assembly frame 6 is assembled in the inner cavity of the installation frame 5. The assembly frame 6 is used for the installation and fixation of a finishing scraper 8. The assembly frame 6 can rotate in the installation frame 5. By adjusting the angle of the assembly frame 6, the finishing scraper 8 can be in two states, perpendicular or parallel to the fixing rod 1, meeting different requirements during the manual operation of finishing the concrete.
[0021] A positioning mechanism 7 is assembled between the installation frame 5 and the assembly frame 6. Through the provided positioning mechanism 7, the assembly frame 6 can be positioned after rotation, so that it maintains a stable rotation angle in the installation frame 5. The top of the assembly frame 6 is fixedly connected through a connecting shaft 61 to a rotating block 62 assembled in the inner cavity of the installation frame 5. The positioning mechanism 7 includes a positioning frame 71. The positioning frame 71 is slidably connected to the inner cavity of the installation frame 5. The side walls of the positioning frame 71 are symmetrically welded and fixed on the left and right with handle frames 73 passing through an opening slot 72. The opening slot 72 is opened on the side wall of the installation frame 5. The handle frames 73 can drive the positioning frame 71 to slide up and down in the inner cavity of the installation frame 5. The bottom of the positioning frame 71 is fixedly connected to a positioning pin 75 passing through a positioning hole 74. The positioning hole 74 is opened in the rotating block 62. The number of the positioning holes 74 and the positioning pins 75 is at least four. The four positioning holes 74 and the positioning pins 75 are evenly distributed in a circle with the center of the positioning frame 71 as the center;
[0022] A telescopic shaft 76 is welded and fixed at the center of the positioning frame 71. The telescopic shaft 76 is inserted into a telescopic groove 77. The telescopic groove 77 is opened at the top of the installation frame 5. A spring 78 is sleeved on the outer side wall of the telescopic shaft 76. Through the elastic force generated by the spring 78 on the positioning frame 71, the positioning pin 75 at the bottom of the positioning frame 71 can maintain the positioning state of the rotating block 62. Through the limitation of the telescopic shaft 76 by the telescopic groove 77 and the limitation of the handle frames 73 by the opening slot 72, the stability of the positioning frame 71 in the inner cavity of the installation frame 5 can be improved, thereby further improving the positioning effect of the positioning frame 71 on the rotating block 62.
[0023] As shown Figure 3 in the figure, an assembly groove 63 is formed at the bottom of the assembly frame 6, and limiting grooves 64 are evenly formed on the side wall of the assembly frame 6. The top of the assembly frame 6 is symmetrically screwed with fastening bolts 65 at the front and back. An assembly block 81 is integrally formed at the top of the finishing squeegee 8. The assembly block 81 is inserted into the assembly groove 63. A fastening screw hole 82 is formed at the top of the assembly block 81. The end of the fastening bolt 65 is screwed into the fastening screw hole 82 to connect and fix the assembly block 81 and the assembly groove 63. Limiting blocks 83 are evenly integrally formed on the side wall of the assembly block 81. When the assembly block 81 is inserted into the assembly groove 63, the limiting blocks 83 are inserted into the limiting grooves 64. Through the interaction between the limiting blocks 83 and the limiting grooves 64, the stability of the connection and fixation between the finishing squeegee 8 and the assembly frame 6 during the finishing operation can be increased. The finishing squeegee 8 is assembled and fixed to the assembly frame 6 through the fastening bolt 65. During construction, the finishing squeegee 8 with corresponding dimensions can be replaced according to construction requirements, and the operation process is simple and convenient.
[0024] Working principle: As shown Figure 1 in Figure 4 and Figure 1 the figure, this device is applicable to manual finishing operation of some narrow areas after the mechanical finishing of bridge deck concrete. First, replace the finishing squeegee 8 with corresponding dimensions according to the construction requirements of the construction area, connect and fix the finishing squeegee 8 to the assembly frame 6, and then during construction, the rotation angle of the assembly frame 6 can be adjusted through the positioning mechanism 7, so that the assembly frame 6 is Figure 4 in a vertical state with the fixed rod 1 as shown Figure 1 in the figure or in a horizontal state with the fixed rod 1 as shown Figure 4 in the figure. When the assembly frame 6 is in the state shown Figure 1 in the figure, the construction worker can hold the first gripping part 2 and the second gripping part 3 with both hands and repeatedly move the finishing squeegee 8 on the concrete surface to perform the finishing operation. When the assembly frame 6 is in the state shown Figure 4 in the figure, the construction worker holds the first gripping part 2 and the second gripping part 3, and with one end of the fixed rod 1 as the axis center, can control the finishing squeegee 8 to move in a fan shape on the concrete surface to perform the finishing operation. This device can be adjusted accordingly according to construction requirements during construction, is simple and convenient to use, and effectively improves the construction efficiency.
