[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0034] Please see the appendix Figure 1-13 This application provides the following technical solutions.
[0035] Example 1: A clamp for magnetic mounting of a structural column includes two clamping arms 1. Each clamping arm 1 has a rotating collar 2 on one side. The clamping arms 1 of the two rotating collars 2 are jointly fitted with a rotating rod 3. The rotating rod 3 contains a first adjusting and locking assembly, which includes a reference shaft block 5, two constraint pressing blocks 12, and several positioning toothed plates 7. Each side of the rotating collar 2 fitted with the rotating rod 3 has several first positioning toothed grooves 8. Several plate grooves 6 are vertically and symmetrically formed inside the rotating rod 3. Several positioning toothed plates 7 are vertically inserted into the plate grooves 6. One side of each positioning toothed plate 7 movably passes through the plate grooves 6 and is inserted into the first positioning toothed groove 8 of the rotating collar 2. An internal groove 4 is formed in the center of the rotating rod 3, connecting the plate grooves 6. The reference shaft block 5 is vertically positioned within the internal groove 4. The positioning toothed plates 7 are positioned near... A groove is provided on one side of the reference shaft block 5. Auxiliary guide grooves 9 are provided on the upper and lower sides of the reference shaft block 5 near the positioning tooth plate 7. The positioning tooth plate 7 is located on both sides of the groove and is horizontally inserted into the two auxiliary guide grooves 9 of the reference shaft block 5. Several first positioning springs 10 are provided between the groove of the positioning tooth plate 7 and the reference shaft block 5. The two clamping arms 1 can be rotated along the rotating rod 3 by rotating collar 2. When rotating, rotating collar 2 contacts the side of the positioning tooth plate 7 extending from the rotating rod 3 through the first positioning tooth groove 8, pushing the positioning tooth plate 7 to move horizontally along the plate groove 6 and the auxiliary guide groove 9. Then, when it reaches the next first positioning tooth groove 8 position, the first positioning spring 10 pushes the positioning tooth plate 7 to continue to insert into the next first positioning tooth groove 8, realizing the rotational movement of the clamping arms 1.
[0036] The rotating rod 3 has several slots 6 connected to its upper and lower ends, each with a clearance slot 11. Two constraint compression blocks 12 are vertically movable within the two clearance slots 11. A prismatic guide block is provided on the side of each clearance slot 11 away from the reference shaft block 5. The prismatic guide block is movably fitted into the center of one side of the constraint compression block 12. An adjusting screw 13 is rotatably inserted into the center of the reference shaft block 5. The upper and lower ends of the adjusting screw 13 are threaded through the centers of the two constraint compression blocks 12 and located outside the rotating rod 3. Several positioning toothed plates 7 are close to the constraint compression blocks. One side of each pressure block 12 is provided with an inclined surface, and the side of each constraint pressing block 12 near the reference shaft block 5 is provided with a tapered surface. The two inclined surfaces of the positioning tooth plate 7 respectively abut against the tapered surfaces of the two constraint pressing blocks 12. When the positioning tooth plate 7 is stably inserted into the first positioning tooth groove 8, and the posture of the clamping arm 1 does not need to be adjusted, the adjusting screw 13 is rotated and the two constraint pressing blocks 12 are moved toward the positioning tooth plate 7 through the thread, so that the constraint pressing blocks 12 limit the horizontal movement of the positioning tooth plate 7, and ensure that the rotational engagement angle of the clamping arm 1 is reliable.
[0037] Two electrically controlled permanent magnet chucks 22 are provided for electromagnetic fixation. The two chucks 22 are respectively located on one side of the two clamping arms 1 via a second adjusting locking assembly and a telescopic adjusting assembly. The telescopic adjusting assembly includes a telescopic arm 16 and a telescopic screw 18. A chuck support rod 21 is horizontally inserted into one side of the telescopic arm 16. A telescopic support groove 15 is horizontally formed on the side of the clamping arm 1 away from the rotating collar 2, and a rotating groove 17 is formed on the side of the clamping arm 1 near the rotating collar 2. The two telescopic arms 16 are respectively movably inserted into the two telescopic support grooves 15. The telescopic screw 18 is rotatably positioned within the telescopic support groove 15, and the telescopic arm 16 is threadedly connected to the telescopic screw 18. 8. One side of the telescopic screw 18 is rotatably inserted into the development slot 17 and is provided with a turning screw head 19. One side of the turning screw head 19 extends out of the clamping arm 1. The outer periphery of the turning screw head 19 is provided with anti-slip texture. The upper end of the development slot 17 is provided with a first clamping bolt 20 through threaded insertion. The lower end of the first clamping bolt 20 is located in the development slot 17 and contacts the anti-slip texture of the turning screw head 19. The telescopic arm 16 can be extended beyond the clamping arm 1 by rotating the telescopic screw 18. The cooperation of the first clamping bolt 20 can ensure that the telescopic screw 18 will not easily rotate, thereby improving the stability of the extension dimension of the telescopic arm 16 to adapt to different construction scenarios.
[0038] The second adjusting locking assembly includes a suction cup support rod 21 and two pressing blocks 24. A horizontally extending, rhomboid mounting hole is provided on one side of the telescopic arm 1 extending from the clamping arm 1. The suction cup support rod 21 is horizontally inserted into the rhomboid mounting hole. Receiving slots 23 are provided on both sides of the rhomboid mounting hole. The two pressing blocks 24 are movably inserted into the two receiving slots 23. Four guide rods 26 are vertically and symmetrically provided on the upper end of the pressing blocks 24. The four guide rods 26 are movably inserted into the telescopic arm 16. Several second positioning tooth grooves 25 are provided on the side of the suction cup support rod 21 near the pressing blocks 24. Several positioning teeth are symmetrically provided on the lower end of the pressing blocks 24. The positioning teeth are respectively inserted into the second positioning... Inside the positioning groove 25, the side of the extrusion block 24 away from the suction cup support rod 21 is provided with a second positioning spring 27. The side of the receiving groove 23 away from the suction cup support rod 21 is provided with a second clamping bolt 28 by threaded insertion. One end of the second clamping bolt 28 abuts against the extrusion block 24. After the angle of the clamping arm 1 and the length of the telescopic arm 16 are adjusted, the position of the electric permanent magnet chuck 22 can be adjusted according to the distance between the electric permanent magnet chuck 22 and the wall. The second clamping bolt 28 abuts against the limit of the extrusion block 24, so that the positioning teeth of the extrusion block 24 are stably inserted into the second positioning groove 25 of the suction cup support rod 21, and the position of the electric permanent magnet chuck 22 is stably maintained.
[0039] Example 2: Based on Example 1, combined with Appendix Figure 13A controller 32 is provided on the side of the clamping arm 1 away from the electrically controlled permanent magnet chuck 22. The controller 32 has two control buttons and is connected to the electrically controlled permanent magnet chuck 22 through the chuck support rod 21. When constructing the construction wall 29, pre-embedded steel plates 31 are set on both sides of the construction position of the structural column. After the angle between the two clamping arms 1 is adjusted, the template 30 is placed on the side of the construction wall 29. Then, the two clamping arms 1 are pressed against the template, and then the electrically controlled permanent magnet chuck 22 contacts the pre-embedded steel plate 31. The electric permanent magnet chuck 22 can be used to attract or detach from the pre-embedded steel plate 31 by operating the buttons on the controller 32. The electric permanent magnet chuck 22 can be a common small standard part with high suction power, which can complete the positioning, clamping and quick demolding of the structural column template.
