[0021] In order to further understand the content of the present invention, the present invention is described in detail with reference to the embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0022] Example 1

[0023] In the construction of bridge projects such as highways, national and provincial trunk roads, when constructing the support pedestals at the bridge cap beam, safety hazards are often caused due to the lack of high-altitude work protection measures. At this time, the temporary protection of the cap beam has been removed, and the workers have nowhere to hang their safety belts for high-altitude work. The lifeline fixing devices in the prior art mostly rely on cooperation with steel beams. The common lifeline fixing devices have the fixed part at the lower end clamped by the flange plate of the I-beam steel beam to achieve the fixation of the device. For the construction of support pedestals similar to those at the bridge cap beam, the above-mentioned common lifeline fixing devices are difficult to fix on the support pedestals with a relatively flat surface. Therefore, this embodiment provides a pre-buried lifeline fixing device with a simple structure, easy-to-obtain parts, low installation requirements, and a wide range of applicable scenarios.

[0024] like Figure 1-5 As shown, this embodiment provides a pre-embedded lifeline fixing device, which includes a device body, the device body includes a sleeve 401 pre-embedded in the shock-proof block, and a connecting rod 201 is detachably provided in the sleeve 401 along the length direction of the sleeve 401. One end of the connecting rod 201 extends out of the sleeve 401 and is connected to the bottom end of a vertical pole 102. A connecting clamp 101 for hanging the lifeline is provided at the top of the vertical pole 102.

[0025] Through the arrangement of the sleeve 401, connecting rod 201, vertical pole 102 and connecting clamp 101 in this embodiment, the construction workers first embed the sleeve in the shockproof block, then assemble the connecting rod and the vertical pole into a rod body, install the connecting clamp on the top of the vertical pole, and first fix the lifeline on one side, and finally install the bottom of the connecting rod in conjunction with the sleeve, thereby providing the construction workers with a lifeline fixing device that can hang a safety belt in the absence of temporary protection during the construction of the support pad stone at the cap beam; secondly, the device has a simple structure and is easy to obtain, and the detachable connection between the sleeve and the connecting rod can realize the rapid installation and removal of the device, and the parts are easy to repair.

[0026] In this embodiment, one end of the sleeve 401 extends outward along the surface of the shockproof stopper to form a limiting ring 402. The limiting ring 402 has a first limiting surface 403 for fitting with the bottom surface of the deep pit surface of the depression of the shockproof stopper.

[0027] Through the setting of the limiting ring 402 and the first limiting surface 403 in this embodiment, after the connecting rod is installed in the sleeve, the force exerted by the connecting rod on the sleeve can be transmitted to the first limiting surface of the limiting ring, thereby increasing the force-bearing area to improve the structural strength and durability of the device.

[0028] In this embodiment, the bottom end of the vertical rod 102 is recessed along the length direction of the vertical rod 102 to form a mounting groove 103 , and one end of the connecting rod 201 can be embedded in the mounting groove 103 .

[0029] By providing the mounting groove 103 in this embodiment, the connecting rod and the vertical rod can be effectively connected.

[0030] In this embodiment, the limiting ring 402 further has a second limiting surface 404 , and the second limiting surface 404 is used to fit with the bottom end surface of the vertical pole 102 when the second limiting surface 404 moves relative to the vertical pole 102 .

[0031] By providing the second limiting surface 404 in this embodiment, the second limiting surface fits the bottom end surface of the vertical rod, which can effectively prevent rust and wear caused by the exposure of the connecting rod.

[0032] In this embodiment, threads 202 are provided on the inner wall of the sleeve 401 and the outer wall of the connecting rod 201 .

[0033] By setting the thread 202 in this embodiment, the relative movement of the second limiting surface and the vertical pole can be completed by screwing the connecting rod to achieve the fit between the second limiting surface and the bottom end surface of the vertical pole, thereby further realizing the quick and convenient installation and removal of the device.

[0034] In this embodiment, one end of the connecting rod 201 is welded into the mounting groove 103 , which can further strengthen the connection between the sleeve and the connecting rod.

[0035] In this embodiment, the port at the other end of the sleeve 401 is closed and the material of the sleeve 401 is polyethylene. The closure of the bottom end of the sleeve can further prevent sand and stones from wearing the threads on the connecting rod. The polyethylene sleeve has high strength and corrosion resistance, and can protect the connecting rod to prevent it from rusting.
