[0003] For example, the Chinese patent with publication number CN111877783B discloses a lifeline column installation and fastening device suitable for box-type steel beams. By designing a driven gear, a driving gear, a central rotating shaft, a turntable, a limit block, a support rod, and a limit block, on the one hand, the central rotating shaft, the driving gear and the turntable are restricted to a fixed horizontal plane through the limiting effect of the support rod and the limit block, thereby avoiding up and down movement when the turntable is rotated, causing rotation error; on the other hand, a limit block is provided on the driving gear to avoid the driving gear and the driven gear from derailing during the movement of the driving gear, thereby causing rotation failure; at the same time, the rotation of the turntable drives the driving gear to rotate, thereby driving the driven gear to rotate, and finally driving a pair of first bolts to rotate in the same direction.

[0004] The drawback of the above-mentioned prior art solution is that the device needs to be disassembled repeatedly to move its position, which greatly reduces work efficiency. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention will be described in further detail below with reference to the accompanying drawings.

[0023] like Figure 1-4 As shown, a movable lifeline installation device for I-beam construction disclosed in the present technical solution includes an adjusting spindle 1. The middle section of the adjusting spindle 1 is smoothly arranged and has threads at both ends, and the threads at both ends rotate in opposite directions. Threads are machined at both ends of the adjusting spindle 1, and second adjusting components 4 are installed at the threads, that is, the second adjusting components 4 are threadedly connected to the adjusting spindle 1. Through the threaded connection and utilizing the characteristics of the bidirectional threaded rod (the adjusting spindle is actually a bidirectional threaded rod), the mutual distance between the two second adjusting components 4 can be adjusted, and it can be used for I-beams of different specifications, thereby improving the applicability of the device.

[0024] The second adjustment assembly 4 includes a sliding fixture 41, with second adjustment nuts 42 mounted on either side of the sliding fixture 41 and threadedly connected to the adjustment spindle 1. The second adjustment nuts 42 enable movement of the sliding fixture 41. By rotating the second adjustment nuts 42, the sliding fixture 41 slides along the adjustment spindle 1. By adjusting the width of the sliding fixture 41, the device can be installed on I-beams of varying widths, reducing manufacturing costs and eliminating the need for disassembly for replacement, saving time.

[0025] In addition, the sliding fixtures 41 can be manufactured in different heights and sizes. Using these different heights and sizes, the device can be installed on I-beams of varying thicknesses, thereby improving the device's applicability, saving work time, and increasing work efficiency. The sliding fixtures 41 can also be made telescopic, allowing for adjustable lengths to clamp beams of varying thicknesses.

[0026] The sliding fixture 41 is a combination of an L-shaped member and a sleeve. The two faces of the L-shaped member are perpendicular to each other, and the two perpendicular end faces are connected to the second cushioning pads 43, which are arranged at right angles. A stiffening plate 44 is provided on the side of the sliding fixture 41 away from the second cushioning pads 43. The second cushioning pads 43 protect the steel beam from damage caused by the sliding fixture 41 when it contacts the steel beam surface. The stiffening plate 44 also provides auxiliary support for the sliding fixture 41, ensuring the clamping strength of the sliding fixture 41.

[0027] The upper side of the middle section of the adjusting spindle 1 is connected with a horizontal plate 2, and the horizontal plate 2 and the adjusting spindle 1 need to be connected with high strength. The horizontal plate 2 is not set here to be absolutely horizontal, and it can be used normally with a slight angle to the horizontal plane. The horizontal state is the ideal state. The horizontal plate 2 is provided with a first adjustment component 3, and the first adjustment component 3 includes an adjustment screw 31, four of which are shown in the figure. The adjustment screw 31 is located at the four corners of the horizontal plate 2. The adjustment screw 31 passes through the horizontal plate 2 and the end is placed outside the horizontal plate 2. The adjustment screw 31 is threadedly connected with a first adjustment nut 32, and the first adjustment nut 32 and the head of the adjustment screw 31 are placed on the same side. The tail of the adjustment screw 31 is provided with a pressure block 33, and the pressure block 33 is not placed on the same side as the first adjustment nut 32. By rotating the height of the pressure block 33 at the end of the adjusting screw 31, the device is fixed to the steel beam. Rollers 34 are mounted on either side of the horizontal plate 2, sleeved around the middle section of the adjustment spindle 1. A fixed block 35 is threaded onto the adjustment spindle 1, located on the side of the rollers 34 facing away from the horizontal plate 2. When the adjustment screw 31 and the pressure block 33 rise, the rollers 34 contact the surface of the steel beam, allowing the device to roll on the beam. Compared to frictional movement, rolling is more labor-efficient and avoids damage to the beam caused by long-term friction.

[0028] A first buffer pad 36 is provided at the bottom of the pressing block 33, and the first buffer pad 36 is fixedly connected to the pressing block 33. The buffer pad can protect the steel beam from being squeezed by the pressing block 33 and damaged when the pressing block 33 contacts the surface of the steel beam.

[0029] The upper side of the horizontal plate 2 is connected to a suspension rod 5, and a suspension ring 6 is installed on the suspension rod 5. Here, the horizontal plate 2 and the suspension rod 5 as well as the suspension rod 5 and the suspension ring 6 must be connected with high strength.

[0030] Working principle: The second adjustment components 4 are installed at both ends of the adjustment main shaft 1, and the second adjustment nuts 42 are installed on both sides of the second adjustment component 4. The second adjustment nuts 42 are used to realize the movement of the sliding fixture 41. The horizontal plate 2 is welded and installed in the middle of the adjustment main shaft 1, and the lifeline suspension vertical rod 5 is installed in the middle part of the horizontal plate 2. Four adjustment screws 31 are symmetrically installed at the four corners of the horizontal plate 2. The ends of the adjustment screws 31 are installed with pressure blocks 33. The bottom of the pressure block 33 and the contact surface with the steel beam are installed with rubber pads. The height of the pressure block 33 at the end of the adjustment screw 31 is adjusted to fix the device to the steel beam. Rollers 34 are installed on both sides of the horizontal plate, and fixed blocks 35 are installed on both sides of the roller 34. When the adjustment screw 31 and the pressure block 33 rise, the roller 34 drops to the surface of the steel beam, and the device can slide on the steel beam.

[0031] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
