DETAILED DESCRIPTION

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1-4 As shown, a movable lifeline installation device for I-beam construction disclosed in the technical solution includes an adjusting spindle 1, the middle section of the adjusting spindle 1 is smoothly arranged and threads are provided at both ends, and the threads at both ends have opposite rotation directions. Threads are processed at both ends of the adjusting spindle 1, and second adjusting components 4 are installed at the threads, that is, the second adjusting component 4 is 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, and second adjustment nuts 42 are installed on both sides of the sliding fixture 41 and the second adjustment nuts 42 are threadedly connected to the adjustment main shaft 1. The movement of the sliding fixture 41 is achieved by the second adjustment nuts 42. By rotating the second adjustment nuts 42, the sliding fixture 41 is pushed to slide on the adjustment main shaft 1. By adjusting the width of the sliding fixture 41, the device can be installed on I-beams of various widths, saving manufacturing costs. At the same time, replacement does not require disassembly, saving working time.

[0025] In addition, the sliding fixtures 41 of different heights can be made, and the device can be installed on I-beams of different thicknesses by using the sliding fixtures 41 of different heights, thereby improving the applicability of the device, saving working time, and improving working efficiency. The sliding fixture 41 can also be made into a telescopic type, and the telescopic sliding fixture 41 can be adjusted in length to clamp steel beams of different thicknesses.

[0026] The sliding fixture 41 is a combination of an L-shaped part and a sleeve, and the two faces of the L-shaped part are perpendicular to each other, and the two vertical end faces are connected with a second buffer pad 43, and the second buffer pad 43 is in a right angle shape. A stiffening plate 44 is provided on the side of the sliding fixture 41 away from the second buffer pad 43. The second buffer pad 43 can protect the steel beam from being squeezed and damaged by the sliding fixture 41 when the sliding fixture 41 contacts the surface of the steel beam, and the stiffening plate 44 can play an auxiliary supporting role 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 main shaft 1 is connected with a horizontal plate 2, and the horizontal plate 2 and the adjusting main shaft 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 with 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, and 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. The device is fixed to the steel beam by rotating the height of the pressure block 33 at the end of the adjusting screw 31. Rollers 34 are provided on both sides of the horizontal plate 2, and the two rollers 34 are sleeved on the middle section of the adjusting spindle 1. A fixed stopper 35 is provided on the side of the roller 34 away from the horizontal plate 2, and the fixed stopper 35 is threadedly connected to the adjusting spindle 1. When the adjusting screw 31 and the pressing block 33 rise, the rollers 34 contact the surface of the steel beam, and the device can roll on the steel beam. Compared with friction movement, rolling is not only more labor-saving, but also can avoid long-term friction on the surface of the steel beam and damage to the steel beam.

[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] A suspension rod 5 is connected to the upper side of the horizontal plate 2, 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 pole 5 is installed in the middle 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, and rubber pads are installed on the bottom of the pressure blocks 33 and the contact surface with the steel beam. The height of the pressure blocks 33 at the ends of the adjustment screws 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 rollers 34. When the adjustment screws 31 and the pressure blocks 33 rise, the rollers 34 fall 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 invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
