[0006] When the bridge hanger body needs to be installed, first insert the bridge hanger body into the top steel pipe, make the nut of the expansion bolt and the hexagonal socket of the tool match, then aim at the hole drilled in advance on the floor slab, and forcefully insert the expansion bolt into the hole; then hold the handle and tighten the expansion bolt by rotating the installation tool, then remove the installation tool, and repeat the above operation to complete the installation of the large-area bridge hanger body; in summary, by adopting the above scheme, there is no need for operators to work at height, thereby solving the unsafe problem existing in the installation process of the bridge hanger body.

[0007] Preferably, the limiting member includes a first through hole opened on the side wall of the bottom steel pipe and an insert rod slidably connected to the first through hole; the side wall of the top steel pipe is sequentially opened with a plurality of second through holes along its axial direction, and the insert rod is inserted into the second through holes.

[0008] By adopting the above scheme, when it is necessary to adjust the height of the top steel pipe, first remove the plug rod, and then move the top steel pipe. When the top steel pipe is moved to a suitable position, the plug rod is moved to be connected to the first through hole and the second through hole, so that the top steel pipe can be limited, thereby adjusting the height of the top steel pipe. In summary, the set limit piece facilitates limiting the top steel pipe, thereby facilitating the adjustment of the height of the top steel pipe.

[0009] Preferably, a connecting mechanism for connecting the bottom steel pipe and the handle is provided between the two.

[0010] By adopting the above solution, the provided connection mechanism makes it easy to install the handle to the bottom of the bottom steel pipe.

[0011] Preferably, the connecting mechanism includes an insert block fixed to the bottom of the bottom steel pipe and a slot opened at the top of the handle; the insert block is inserted into the slot, and a limiting component for limiting the insert block is installed in the slot.

[0012] By adopting the above scheme, when the handle needs to be installed on the bottom of the bottom steel pipe, the handle is first moved to insert the plug into the slot, and then the plug is limited by the limiting assembly, so that the handle can be installed on the bottom of the bottom steel pipe; the provided connecting mechanism facilitates the installation of the handle on the bottom of the bottom steel pipe.

[0013] Preferably, the limit assembly includes a first slide groove opened on one side of the slot, a limit block slidably connected to the first slide groove, and a pull rod fixed to the end of the limit block away from the insertion block; a limit groove for the limit block to be plugged into is opened on one side of the insertion block, and the end of the pull rod away from the limit block passes through the side wall of the first slide groove.

[0014] By adopting the above scheme, when the insert block needs to be limited, the limit block is first moved by the pull rod so that the limit block is inserted into the limit groove, thereby limiting the insert block; the set limit assembly facilitates the limitation of the insert block.

[0015] Preferably, a slider is fixedly connected to one side of the limit block, a second slider is provided on one side of the first slider for sliding the slider, a spring is fixedly connected to one side of the slider, and one end of the spring away from the slider is fixed to an inner wall of one end of the second slider; a slope is provided on the side of the limit block close to the insert block.

[0016] By adopting the above scheme, when the plug block is inserted into the slot, the plug block drives the limit block to move under the action of the inclined surface, the movement of the limit block drives the movement of the slider, and the movement of the slider presses the spring. When the plug block is inserted into the slot, the slider drives the limit block to be inserted into the limit slot under the action of the spring, thereby reducing the possibility of separation of the limit block and the limit slot.

[0017] Preferably, a protective cover is installed on the handle.

[0018] By adopting the above solution, the protective cover is provided, which is convenient for protecting the hands of the operator.

[0022] 1. When the bridge hanger body needs to be installed, first insert the bridge hanger body into the top steel pipe, make the nut of the expansion bolt and the hexagonal sleeve of the tool match, then aim at the hole pre-punched on the floor slab, and forcefully insert the expansion bolt into the hole; then hold the handle and tighten the expansion bolt by rotating the installation tool, then remove the installation tool, and repeat the above operation to complete the installation of the large-area bridge hanger body; In summary, by adopting the above solution, there is no need for operators to work at height, thereby solving the unsafe problem existing in the installation process of the bridge hanger body;

[0023] 2. When the height of the top steel pipe needs to be adjusted, first remove the insertion rod, then move the top steel pipe. When the top steel pipe is moved to a suitable position, move the insertion rod so that the insertion rod is inserted into the first through hole and the second through hole, so that the top steel pipe can be limited, thereby adjusting the height of the top steel pipe. In summary, the setting of the limiter facilitates the limitation of the top steel pipe, thereby facilitating the adjustment of the height of the top steel pipe.

[0024] 3. When the handle needs to be installed at the bottom of the bottom steel pipe, first move the handle to insert the plug into the slot, and then limit the plug through the limit assembly, so that the handle can be installed at the bottom of the bottom steel pipe; the provided connection mechanism facilitates the installation of the handle at the bottom of the bottom steel pipe.
