Detailed Description
The following describes embodiments of the present invention in detail with reference to the drawings, and the embodiments are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific construction processes are given, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1-3, the clamping and controlling device for accurately positioning the web steel bars of the precast box girder consists of a support frame, a horizontal bar adjusting and positioning mechanism and a vertical bar adjusting and positioning mechanism.
The support frame comprises a bottom frame 101 of rectangular configuration, on which four inclined frames 102 are welded. Each inclined frame 102 is composed of an outer inclined rod and an inner inclined rod which are arranged in parallel, and a horizontal connecting rod for connecting the two; diagonal braces are also welded between the outboard diagonal bars and the bottom frame 101 for structural stability. The four inclined frames 102 are divided into two left and right rows, each row is two, and the inclination angles of the outer inclined rods in the inclined frames 102 in the same row are the same.
All install a horizontal muscle adjustment positioning mechanism in every inclined frame 102, it includes and articulates first adjusting lever 201 and the second adjusting lever 202 that links to each other with the outside down tube, and the other end of first adjusting lever 201 and second adjusting lever 202 all links to each other with the backplate that broach 203 was placed to the horizontal muscle is articulated. The first adjusting rod 201 and the second adjusting rod 202 are equal in length, and the back plate of the horizontal rib placing comb teeth 203 and the outer oblique rods are parallel to each other, so that a deformable parallelogram structure is formed. In order to adjust the specific shape of the parallelogram and position the parallelogram so as to change the coordinate position of the horizontal rib in the vertical direction, an adjusting screw 204 connected with an outside diagonal rod is arranged on the back plate of the horizontal rib placing comb teeth 203. Specifically, a first hinge 205 is installed on the back plate of the comb teeth 203 for placing the horizontal ribs, a second hinge 206 is installed on the inclined rod on the outer side, one end of the adjusting screw 204 is rotatably connected with the first hinge 205, the other end of the adjusting screw is connected with the second hinge 206 in a threaded manner, and the height of the comb teeth 203 for placing the horizontal ribs can be adjusted by rotating the adjusting screw 204 forwards or backwards. Under the general condition, set up on the inboard down tube and place the vertical slot hole that broach 203 position corresponds with the horizontal muscle, make the horizontal muscle place broach 203 and can wear out inboard down tube smoothly.
The vertical rib adjusting and positioning mechanism comprises vertical rib positioning comb teeth 301 located between adjacent inclined frames 102 in the same row and a horizontal slide rail 302 connected with an outer side inclined rod, and two ends of the vertical rib positioning comb teeth 301 are connected with the horizontal slide rail 302 in a sliding mode.
