Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of supporting devices, in particular to a highway base construction template supporting device. Background Art
[0002] At present, most highway base layers use one-time cast-in-place concrete. Before pouring concrete, it is generally necessary to surround the pouring site with a construction template. The template is usually made of steel and looks like a large steel puzzle. It can be quickly assembled into the skeleton of the road. When using the construction template, a supporting device is required to support the template to prevent the template from collapsing due to lack of support points. The supporting device needs to be used in conjunction with the positioning rod to increase stability.
[0003] Most of the template support devices currently in use have multiple support points, but the support devices do not have the function of storing and positioning the support points, which increases the floor space during transportation. At the same time, when the support points are used in conjunction with bolts, the support points need to be turned to a suitable angle one by one, and the angles of all the support points cannot be adjusted at one time. In addition, most of the current templates are fixed by bolts, and auxiliary tools need to be used for installation and disassembly, which is more cumbersome. Utility Model Content

One side of the surface of the tripod 6 is fixedly connected with a support sleeve rod 7. When the tripod 6 rotates, it can drive the support sleeve rod 7 to rotate. When the support sleeve rod 7 needs to be fixed, the staff can use suitable bolts to position the support sleeve rod 7, thereby achieving the effect of supporting the template body 1. A reset mechanism 8 is provided on one side of the interior of the template body 1. Under the action of the reset mechanism 8, the synchronous adjustment mechanism 3 can return to its original position. The upper and lower sides of the inner wall of the template body 1 are bolted with mounting seats 9, and the inner wall of the mounting seat 9 is fixedly connected with a fixing rod 10. A positioning mechanism 11 is provided on one side of the mounting seat 9. The two template bodies 1 are used as a group, and the two template bodies 1 can be connected under the action of the positioning mechanism 11.
[0023] The synchronous adjustment mechanism 3 includes a rack plate 31, and the surface of the rack plate 31 is slidably connected to the inner wall of the slide rail 2. When the one-way threaded rod 4 rotates and moves toward the inside of the template body 1, it contacts one side of the surface of the rack plate 31, and continues to rotate the one-way threaded rod 4. Under the action of the one-way threaded rod 4, the rack plate 31 can be moved. The inner wall of the template body 1 is rotatably connected with a linkage rod 33. There are four linkage rods 33. One side of the surface of the linkage rod 33 is fixedly connected with a spur gear 32. One side of the surface of the spur gear 32 is meshed with one side of the surface of the rack plate 31. When the rack plate 31 moves, the spur gear 32 can be driven to rotate. When the spur gear 32 rotates, the linkage rod 33 can be rotated. One side of the surface of the linkage rod 33 is bolted to one side of the surface of the tripod 6. When the linkage rod 33 rotates, the tripod 6 can be driven to rotate.
[0024] The reset mechanism 8 includes a fixed plate 81, the upper and lower ends of the fixed plate 81 are bolted to the inner wall of the template body 1, a telescopic rod 82 is bolted to one side of the surface of the fixed plate 81, the other end of the telescopic rod 82 is bolted to one side of the surface of the rack plate 31, when the rack plate 31 moves, the telescopic rod 82 can be driven to contract, a telescopic spring 83 is fixedly connected to one side of the surface of the fixed plate 81, the other end of the telescopic spring 83 is fixedly connected to one side of the surface of the rack plate 31, when the rack plate 31 moves, the telescopic spring 83 can be compressed, the telescopic rod 82 is located on the inner wall of the telescopic spring 83, and the elastic range of the telescopic spring 83 is greater than the telescopic range of the telescopic rod 82.
[0025] The positioning mechanism 11 includes a rotating rod 111, one side of the surface of the rotating rod 111 is designed in an arc shape, and under this design, the rotating rod 111 can be easily rotated. The inner wall of the rotating rod 111 is rotatably connected to the surface of the fixed rod 10. A through groove 112 is provided on the surface of the rotating rod 111. There is enough gap between the rotating rod 111 and the inner wall of the mounting seat 9 to prevent the fixed rod 10 from hindering the rotation of the rotating rod 111. A screw rod 113 is fixedly connected to the bottom of the inner wall of the template body 1 on one side, and a block 114 is threadedly connected to the surface of the screw rod 113. The block 114 is designed in a diamond shape and the block 114 is rotated to a suitable position. When the size of the block 114 is set, it is larger than the width of the through slot 112. When the two template bodies 1 are to be connected, the block 114 is rotated so that the block 114 can pass through the through slot 112. The rotating rod 111 is rotated with the fixed rod 10 as the center point so that the rotating rod 111 is under the block 114. When the rotating rod 111 is under the block 114, the block 114 is rotated so that the block 114 descends and fits the top of the rotating rod 111. At this time, the block 114 and the through slot 112 are staggered. Under this design, the rotating rod 111 can be limited, and the two template bodies 1 can be connected under this action.
[0026] Working principle: when the formwork body 1 is to be supported, the one-way threaded rod 4 is rotated to make the one-way threaded rod 4 rotate and move toward the inside of the formwork body 1. When the one-way threaded rod 4 contacts one side of the surface of the rack plate 31, the one-way threaded rod 4 continues to be rotated. Under the action of the one-way threaded rod 4, the rack plate 31 can be moved. When the rack plate 31 moves, the spur gear 32 can be rotated. When the spur gear 32 rotates, the linkage rod 33 can be rotated. When the linkage rod 33 rotates, the tripod 6 can be driven to rotate. When the tripod 6 rotates, the support sleeve rod 7 can be driven to rotate. When the support sleeve rod 7 rotates to a certain distance, the one-way threaded rod 4 is stopped from rotating. The staff can use an adapted positioning rod to fix it into the ground through the inner cavity of the support sleeve rod 7. At the same time, when the rack plate 31 moves, the telescopic rod 82 can be contracted and the telescopic spring 83 can be compressed. When the template body 1 is not in use, the one-way threaded rod 4 is rotated in the opposite direction so that the one-way threaded rod 4 no longer contacts the rack plate 31. Under the action of the telescopic rod 82, the rack plate 31 can be driven to move to the outside of the template body 1. When the rack plate 31 moves outward, the telescopic rod 82 can be extended. When the rack plate 31 moves outward, the four supporting sleeve rods 7 can be driven to rotate into the interior of the template body 1 at the same time. When two template bodies 1 are to be connected, the block 114 is rotated so that the through groove 112 can pass through the block 114, and the rotating rod 111 is rotated so that the rotating rod 111 passes through the block 114. When the rotating rod 111 is below the block 114, the block 114 is rotated so that the block 114 fits the top of the rotating rod 111, and the rotating rod 111 is limited to prevent the rotating rod 111 from moving easily.
