[0027] L-shaped support blocks 11 are provided around the inner bottom of the groove 18, corresponding to the outer sides of the circular groove 13. These L-shaped support blocks 11 have openings on the outer walls corresponding to the stopper rods 2. Opposing L-shaped rods 27 are provided on either side of the second threaded block 28. Both L-shaped rods 27 are U-shaped, and the corresponding support frames 24 are provided with rod slots.

[0028] Springs 12 are provided between the L-shaped support blocks 11 outside the circular groove 13 , and a slot 6 is provided at the bottom of the circular groove 13 corresponding to the embedded groove 5 .

A lifting block 9 is provided on the side of the threaded block 8 away from the limit rod 2, and a rotating pressure block 20 is provided on the top of the lifting block 9.

The rotating pressure block 20 is manually rotated to rotate to the top of the I-beam 3, and then the pin 19 is used to limit the outside of the rotating pressure block 20, so that the inner frame 7 and the rotating pressure block 20 can limit and fix the I-beam 3 to prevent it from shifting.

[0030] The bottom end of the screw rod 10 and the middle section of the screw rod 26 are both optical axes, and a gear 14 is provided on the screw rod 10 and the screw rod 26. A turntable 16 is provided on one side of the inner frame 7 and the support frame 24 at a position corresponding to the gear 14. The turning rod of the turntable 16 is movably connected to the inner frame 7 and the support frame 24 through a bearing. The other end of the turning rod of the turntable 16 is connected to the gear 2 15. The gear 2 15 and the gear 14 are meshed with each other. An opening is provided on the other side of the inner frame 7 at a position corresponding to the screw rod 10, and a slot is provided on the top of the inner frame 7 at a position corresponding to the lifting block 9, so that the work The personnel place the I-beam 3 in a pre-set position and evenly open embedded grooves 5 on both sides of it. Then, the limit rod 2 is placed in the embedded groove 5, so that the inner frame 7 inside the limit rod 2 fits with the two sides of the I-beam 3. Then, the threaded rod 4 on the top of the limit rod 2 is rotated so that the bottom end of the threaded rod 4 rotates downward and inserts into the circular groove 13. The L-shaped support block 11 outside the circular groove 13 can be squeezed outward through the opening, so that the L-shaped support block 11 can support the inner wall of the embedded groove 5, preventing the limit rod 2 from shifting when filling, which would affect its subsequent limiting and fixing effect. When the limit rod 2 is moved, the L-shaped support block 11 can be prevented from sliding through the opening by the action of the spring 12. When the limiting rod 2 and the rotating pressure block 20 are fixed, the turntable 16 outside the support frame 24 can be rotated to drive the gear 2 15 on the rotating rod to rotate, and the gear 2 15 drives the gear 1 14 engaged with it to rotate, and the gear 14 drives the screw rod 2 26 to rotate, and the screw rod 2 26 drives the threaded block 2 28 to move upward, so that the threaded block 28 drives the L-shaped rod 27 to move together, and the L-shaped rod 27 drives the support plate 25 to move in the opposite direction to support the inner side of the I-beam 3, which can make its limiting and fixing effect better.

[0031] A slider 23 is provided at the middle position of the bottom of the L-shaped support block 11 near the circular groove 13, and a slide groove 17 is provided in the groove 18 in the middle of the bottom of the L-shaped support block 11, and the slide groove 17 is slidably connected to the slider 23, so that when the L-shaped support block 11 is subjected to the extrusion force of the threaded rod 4, the slider 23 at the bottom of the L-shaped support block 11 can move in the slide groove 17, which can make the L-shaped support block 11 move more stably.

[0032] The rotating pressure block 20 is evenly provided with pin grooves on the lifting block 9 near one end of the limit rod 2, and pins 19 are provided in the pin grooves of the lifting block 9. After the staff rotates the rotating pressure block 20, the pins 19 can be installed on the outside of the rotating pressure block 20 to limit it and prevent it from deflecting during rotation.

[0033] The top of the limiting rod 2 is provided with an external thread, and the top of the limiting rod 2 is connected to a protective cover 29 through a thread. After the threaded rod 4 is screwed in, the protective cover 29 can be screwed onto the limiting rod 2 to protect the top of the threaded rod 4.

[0034] When the embodiment of the present application is in use, the staff places the I-beam 3 in a pre-set position and evenly opens embedded grooves 5 on both sides thereof. Then, the limiting rod 2 is placed in the embedded groove 5 so that the inner frame 7 inside the limiting rod 2 fits with both sides of the I-beam 3. Then, the threaded rod 4 at the top of the limiting rod 2 is rotated so that the bottom end of the threaded rod 4 rotates and moves downward to be inserted into the circular groove 13. The L-shaped support block 11 outside the circular groove 13 can be squeezed outward through the opening. When the L-shaped support block 11 moves, the slider 23 at the bottom can move in the slide groove 17, so that the L-shaped support block 11 can move more stably. Then, the L-shaped support block 11 can support the inner wall of the embedded groove 5, so as to prevent the limiting rod 2 from shifting when filling and affecting its subsequent limiting and fixing effect. When the limiting rod 2 is moved, the L-shaped support block 11 can be prevented from sliding through the opening by the action of the spring 12. Then, the protective cover 29 can be screwed on the limiting rod 2 to protect the top of the threaded rod 4.

[0035] After the limit rod 2 is fixed, the turntable 16 on the outside of the inner frame 7 can be rotated to drive the gear 2 15 on the rotating rod to rotate, and the gear 2 15 drives the gear 14 with its core to rotate, so that the gear 14 drives the threaded block 18 on the screw rod 10 to move, and the threaded block 18 drives the lifting block 9 to move, so that the lifting block 9 drives the rotating pressure block 20 to rise to the top of the I-beam 3 and then stop moving. Then manually rotate the rotary pressing block 20 to make it rotate to the top of the I-beam 3, and then use the pin 19 to limit the outside of the rotary pressing block 20, so that the inner frame 7 and the rotary pressing block 20 can be used to limit and fix the I-beam 3 to prevent it from shifting. Then the turntable 16 on the outside of the support frame 24 can be rotated to drive the gear 2 15 on the rotating rod to rotate, and the gear 2 15 drives the gear 1 14 engaged with it to rotate, and the gear 1 14 drives the screw rod 26 to rotate, and the screw rod 26 drives the threaded block 28 to move upward, so that the threaded block 28 drives the L-shaped rod 27 to move together, and the L-shaped rod 27 drives the support plate 25 to move in the opposite direction to support the inside of the I-beam 3, which can make its limiting and fixing effect better.

[0036] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of the embodiments.
