DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-Figure 6 The utility model provides a technical solution: a suspended embedded anchor bolt positioning device, comprising: a bracket 1 and a first support plate 15, a top plate 2 is arranged on the top of the bracket 1, a positioning ring plate 3 is arranged on the top of the top plate 2, and an anchor rod body 4 is fixedly connected inside the positioning ring plate 3,

[0029] A fixing plate 5 is welded and fixed to the bottom of the top plate 2, and the interior of the fixing plate 5 is movably connected to the bracket 1 through a bearing. A connecting plate 6 is welded and fixed to the middle part of the top plate 2, and an adjusting shaft 7 is movably connected to the interior of the connecting plate 6 through a bearing. A handle 8 is fixedly connected to one end of the adjusting shaft 7, and a lever 9 is movably connected to the interior of the handle 8 through a rotating shaft, and a clamping rod 10 is slidably connected to one side of the lever 9; a movable groove matching the lever 9 is provided inside the clamping rod 10, and a spring 11 is connected to one side of the clamping rod 10, and one end of the spring 11 is connected to the handle 8; a plurality of clamping grooves 12 matching the clamping rod 10 are provided on one side of the connecting plate 6, and the clamping grooves 12 are distributed at equal angles with respect to the rotation axis of the adjusting shaft 7; a bidirectional worm 13 is fixedly connected to one end of the adjusting shaft 7, and a worm wheel 14 is meshingly connected to the outer side of the bidirectional worm 13, and the worm wheel The interior of 14 is fixedly connected to the bracket 1, and one end of the bidirectional worm 13 is movably connected to the connecting plate 6 through a bearing; a rotating groove matching the first support plate 15 is provided at the bottom of the bracket 1, and the first support plate 15 is movably connected to the rotating groove, and the first threaded rod 16 is connected to the internal thread of the first support plate 15; a conical block 17 is fixedly connected to one end of the first threaded rod 16, and a first limit block 18 is provided on one side of the conical block 17, a sliding groove matching the first limit block 18 is provided inside the first support plate 15, and the first limit block 18 is slidably connected to the sliding groove; an annular groove matching the first limit block 18 is provided inside the bracket 1, and the first limit block 18 is slidably connected to the annular groove, the lever 9 forms a rotating structure with the handle 8 through a rotating shaft, and the clamping rod 10 and the clamping groove 12 form a clamping structure.

[0030] When the lever 9 is pressed, the lever 10 is rotated inside the clamping rod 10. When the lever 9 is rotated, the roller on one side pushes the clamping rod 10 to move, so that the clamping rod 10 squeezes the spring 11 on one side. When the clamping rod 10 is out of engagement with the clamping groove 12, the handle 8 can be rotated to drive the adjusting shaft 7 to rotate. The adjusting shaft 7 can drive the two-way worm 13 to mesh with the two sets of worm gears 14, so that the two sets of worm gears 14 rotate in relative directions. The two sets of worm gears 14 can drive the two sets of brackets 1 to rotate as well, so that the height of the top plate 2 changes. After the adjustment is completed, the handle 8 is released. At this time, the spring 11 will be reset, pushing the clamping rod 10 to move and engage with the clamping groove 12 on one side of the connecting plate 6. After the engagement is completed, the handle 8 can be limited to prevent the handle 8 from moving and causing the height of the top plate 2 to change.

[0031] When the bottoms of the two groups of brackets 1 are close to each other, the supporting effect on the top plate 2 will become worse, and the bracket 1 is prone to tipping over. The first support plate 15 is rotated to expand and contact the ground, and then the first threaded rod 16 is rotated to perform threaded transmission with the first support plate 15. When the first threaded rod 16 moves, it will drive the conical block 17 to squeeze the first limit block 18 on one side, so that the two groups of first limit blocks 18 move. The first limit block 18 will abut against the rotating groove inside the bracket 1, increasing the friction force when the first support plate 15 rotates, so that the position of the first support plate 15 is fixed. At this time, the expanded first support plate 15 can stably support the bracket 1. In this way, the above operation can facilitate the adjustment of the overall height of the positioning device, and facilitate the positioning of the suspended embedded anchor bolts.

[0032] See also Figure 1 , Figure 3 and Figure 7 The internal thread of the top plate 2 is connected to the second threaded rod 19, and the top of the second threaded rod 19 is welded and fixed with a second limit block 20; the interior of the second limit block 20 is provided with a rolling groove matching the ball 21, and the ball 21 is rollingly connected to the rolling groove; the outer side of the second limit block 20 is movably connected to a second support plate 22, and the interior of the second support plate 22 is provided with a rotating groove matching the second limit block 20, and the top of the second support plate 22 is fixedly connected with a rubber pad 23, and the top plate 2 and the second threaded rod 19 constitute a threaded transmission structure.

[0033] In specific implementation, the suspended column foot is a secondary optimization of the node of the conventional steel column foot. When the suspended column foot is installed, it needs to be positioned by a positioning device. In order to make the positioning ring plate 3 stably placed on the top plate 2, the second threaded rod 19 is rotated to perform threaded transmission with the top plate 2. When the second threaded rod 19 moves, it will drive the rubber pad 23 to contact the positioning ring plate 3 through the second support plate 22. The rubber pad 23 will generate friction with the positioning ring plate 3, thereby fixing the position of the second support plate 22 and the rubber pad 23. At this time, the second threaded rod 19 is rotated to perform threaded transmission with the top plate 2. When the threaded rod 19 is moved, the second threaded rod 19 will contact the second support plate 22 through the ball 21 on the top of the second limit block 20, thereby reducing the resistance to the rotation of the second threaded rod 19 while pushing the second support plate 22 to continue to move upward. By adjusting the second threaded rod 19 of the top plate 2 at different positions, the positioning ring plate 3 can be placed horizontally and stably, which is convenient for positioning the suspended embedded anchor bolt. In this way, the above operation can facilitate local fine-tuning of the positioning ring plate 3 in the suspended embedded anchor bolt, thereby ensuring that the embedding quality of the embedded part meets the design and specification requirements.

[0034] To sum up: when using the suspended embedded anchor bolt positioning device, first adjust the height of the bracket 1 to meet the construction needs, and then place the positioning ring plate 3 on the top plate 2 on the top of the bracket 1. The anchor rod body 4 is fixed in the positioning ring plate 3. At this time, the positioning of the suspended embedded anchor bolt is completed. This is the characteristic of the suspended embedded anchor bolt positioning device.
