[0038] Example 1

[0039] Additional aspects and advantages of embodiments of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of embodiments of the present invention. Figure 1-Figure 7 , an embodiment of the present invention provides a movable safety construction hanger, comprising:

[0040] A support sleeve 1 is provided with two slides 3 on the side wall of the support sleeve 1, the slides 3 are slidably connected to the support sleeve 1, a swivel seat 11 is provided at the bottom of the support sleeve 1, the swivel seat 11 is rotatably connected to the support sleeve 1, a screw rod 2 is provided inside the support sleeve 1, the screw rod 2 is provided along the central axis of the support sleeve 1 and passes through the support sleeve 1; sealing end covers 16 are respectively provided at both ends of the support sleeve 1, and the sealing end covers 16 are fixedly connected to the support sleeve 1 by bolts 5, and both ends of the screw rod 2 pass through the two sealing end covers 16 and are rotatably connected to the sealing end covers 16.

[0041] A fixing plate 8 and two screw rods 7 are fixedly connected to the horizontal boss at the top of the slide 3. The two screw rods 7 are located on the same side of the fixing plate 8 and away from the fixing plate 8. A pressure plate 9 is provided on the fixing plate 8. The bottom surface of the pressure plate 9 is parallel to the horizontal boss. A rectangular groove is provided on one side of the pressure plate 9. The fixing plate 8 is embedded in the rectangular groove and slidably connected to the rectangular groove. A connecting plate 4 is fixedly connected to the inner arc surface of the bottom of the slide bottom 3. The bottom of the connecting plate 4 is fixedly connected to the threaded sleeve 6. The screw rod 2 is passed through the threaded sleeve 6 and is threadedly connected to the threaded sleeve 6. In the embodiment of the present invention, the slide 3, screw rod 7, fixing plate 8 and pressure plate 9 cooperate with each other to form a slot for engaging with the I-beam 17. When in use, the screw rod 2 and support sleeve 1 are firmly clamped to the I-beam 17. The size of the slot can be adjusted according to actual needs during use, so that the device can be applied to different types of steel structure beams.

[0042] A U-shaped connecting lock 12 and an L-shaped bracket 13 are fixedly connected to the bottom of the swivel base 11. A limiting rod 14 is provided on the L-shaped bracket 13. The top of the limiting rod 14 passes through the L-shaped bracket 13 and extends into the interior of the swivel base 11. A spring 15 is sleeved on the limiting rod 14 located between the swivel base 11 and the L-shaped bracket 13. A limiting ring is sleeved on the limiting rod 14 between the spring 15 and the swivel base 11. One end of the limiting rod 14 located inside the swivel base 11 is tightly pressed against the connecting platform 102. In the embodiment of the present invention, by providing the limiting rod 14, the limiting rod 14 can be pulled to contact and press against the connecting platform 102, so that the swivel base 11 on the connecting platform 102 can be rotated according to actual needs. By connecting or hanging a safety rope on the connecting lock 12 on the swivel base 11, when construction workers need to move or change positions, they can easily adjust the position of the connecting lock 12 and the safety rope to prevent the safety rope from being entangled during frequent movements, thereby improving the safety of the device.

[0043] Specifically, one end of the pressing plate 9 is fixedly connected to two ear plates, which are respectively sleeved on the screw rod 7 and slidably connected to the screw rod 7. By arranging two ear plates on the pressing plate 9 and sleeved on the screw rod 7, the pressing plate 9 can slide up and down on the screw rod 7.

[0044] Specifically, a locking nut 10 is provided on the screw rod 7. The locking nut 10 is located above the ear plate and passes through the screw rod 7. The locking nut 10 is threadedly connected to the screw rod 7. By arranging the locking nut 10 on the screw rod 7, the height of the pressing plate 9 can be adjusted and limited.

[0045] Specifically, a guide groove 101 is defined at the top of the support sleeve 1, and the connecting plate 4 is embedded in and slidably connected to the guide groove 101. Two guide bars 103 are symmetrically provided on either side of the support sleeve 1. A slide groove 301 is defined on either side of the inner curved surface of the slide seat 3, and the guide bars 103 are embedded in and slidably connected to the slide groove 301. The interaction between the guide groove 101 and the connecting plate 4, and between the guide bars 103 and the slide groove 301, enables the slide seat 3 to move freely on the support sleeve 1.

[0046] Specifically, a connecting truncated platform 102 is fixed to the bottom of the supporting sleeve 1, and the bottom of the connecting truncated platform 102 is embedded in the rotating seat 11 and is rotatably connected to the rotating seat 11. This structure enables the rotating seat 11 to rotate relative to the connecting truncated platform 102.

[0047] Specifically, the threads of the screw rod 2 and the two slides 3 are in opposite directions. Since the screw rod 2 has two sections of threads with opposite directions on a section of the outer circumference located inside the support sleeve 1, rotating the screw rod 2 can realize the opposite movement of the two slides 3.

[0048] Example 2

[0049] Combine Figure 8 The embodiment of the present invention provides a method for using a movable safety construction hanger, comprising:

[0050] S1. Rotate the screw 2 to move the two slides 3 mounted on the support sleeve 1 relative to each other in the direction close to the I-beam 17, so that the two slots formed by the slides 3, the fixing plate 8 and the pressure plate 9 are respectively fixed to the two sides of the bottom plate of the I-beam 17;

[0051] S2. Manually tighten the lock nut 10 to clamp the pressure plate 9 against the bottom plate of the I-beam 17;

[0052] S3, buckle the construction safety rope on the connecting lock 12 and perform construction at the clamping position;

[0053] S4. When movement is required, loosen the locking nut 10 to move the slot formed by the slide 3, the fixing plate 8 and the pressing plate 9 along the bottom plate of the I-beam 17 to the construction position, and re-tighten the locking nut 10 to clamp it on the bottom plate of the I-beam 17;

[0054] S5. When the I-beam 17 needs to be replaced, loosen the locking nut 10 and rotate the screw in the opposite direction of step S1 to move the pressure plate 9 and the slide 3 away from the I-beam 17. After replacing the I-beam 17, repeat steps S1-S4.

The hanger is fixed to the beam by setting a slot composed of a slide, a screw, a fixed plate and a pressure plate. When in use, the hanger is firmly clamped on the beam with the screw and the support sleeve. The size of the slot can be adjusted according to actual needs during use, so that the device can be applied to different types of steel structure beams. When it is necessary to move, there is no need to release the device from the beam. It is only necessary to loosen the locking nut appropriately and release the fastening of the pressure plate to the beam to move the device. It is easy to use and improves construction safety. By pulling the limit rod so that the limit rod contacts and presses against the connecting round table, the swivel seat on the connecting round table can be rotated as needed. The safety rope is connected or hung by the connecting lock buckle fixed on the swivel seat.
