Description

Technical Field

[0001] This utility model relates to the field of lifeline fixing technology, specifically a lifeline fixing device for inter-column support in foundation pits. Background Technology

[0002] In the construction of deep foundation pits, the support method of concrete supports + lattice column supports is a common form of foundation pit support. As the earthwork excavation proceeds, the bottom concrete supports become the main pedestrian passage during the construction of the basement structure. Since there is a height difference of more than 2m between the support surface and the bottom of the foundation pit, personnel need to attach safety belts to the safety lifelines set between the lattice columns to ensure safety when passing through.

[0003] Traditional methods of installing lifelines present two main problems: First, the traditional method connects adjacent lattice columns by winding the lifelines around the angle steel of the columns. However, this method has been found to cause friction between the lifelines and the angle steel, leading to wear and tear over time and jeopardizing the safety of pedestrians. Regular inspection and replacement are necessary. Second, adjusting the lifeline installation according to construction progress is time-consuming and dangerous, making the reuse of lifelines cumbersome. Therefore, finding a convenient and quick way to install and remove lifelines between lattice columns in the foundation pit, and achieving efficient reuse of these lifelines, is a pressing issue that needs to be addressed. Utility Model Content

[0004] In view of the above-mentioned prior art, this utility model proposes a lifeline fixing device for the support between grid columns in foundation pits. It is simple and convenient to operate, efficient in turnover, safe and reliable. It can effectively realize the fixing and turnover of lifelines between grid columns in deep foundation pits, avoid the traditional method of fixing lifelines by wrapping them around grid columns, and improve the safety of lifeline use and turnover.

[0005] This utility model provides a lifeline fixing device for inter-support grid columns in foundation pits, including a support rope fixed between two adjacent grid columns; the grid column is provided with a support assembly, the support assembly includes two support plates arranged opposite each other, the two support plates are connected by a telescopic assembly, and the end of the support rope is detachably connected to the support plate by a connecting assembly.

[0006] Preferably, the telescopic assembly includes two X-shaped telescopic rods, which are respectively disposed at the top and bottom of the two support plates.

[0007] Preferably, the X-shaped telescopic rod includes two hinged telescopic rod units, and the ends of the telescopic rod units are connected to the connecting lugs provided on the support plate by connecting bolts.

[0008] Preferably, the connecting assembly includes a hollow connecting rod, with a disc at each end of the hollow connecting rod, and the end of the support rope passing through the hollow connecting rod and having a rope buckle; the support plate has a large-diameter pin hole and a small-diameter pin hole, which are connected by a transverse connecting hole; the diameter of the disc is larger than the diameter of the small-diameter pin hole and smaller than the diameter of the large-diameter pin hole, and the length of the hollow connecting rod is slightly greater than the thickness of the support plate.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The two support plates can be freely extended through the telescopic components. When extended, the support plates can be firmly attached to the inside of the angle steel of the lattice column, ensuring that the steel wire rope, i.e. the lifeline, is effectively connected to the lattice column. When retracted, the support plates can be easily removed from the lattice column through the gap between the angle steel, realizing quick disassembly and turnover.

[0010] 2. The end caps of the wire rope can be easily and quickly inserted and fixed through the pin holes on the support plate. The wire rope can pass through the hollow connecting rod and the length of the wire rope can be adjusted by the buckle at the end to adapt to different spacings between lattice columns. It is simple to operate, highly adaptable, and has a high turnover rate.

[0011] 3. The device of this utility model can be quickly installed, dismantled and adjusted to ensure the stable connection and rapid turnover of the lifeline between the lattice columns. It can also be set in sections, which solves the problems of difficult installation and dismantling, wire rope sagging, wire rope wear and low turnover rate caused by the traditional long steel wire rope winding around the lattice column.

Detailed Implementation

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Example: Figure 1-2The device shown is a lifeline fixing device for inter-branch support of lattice columns in a foundation pit, including a steel wire rope 8 fixed between two adjacent lattice columns 12.

[0017] Furthermore, the lattice column 12 is internally equipped with a support assembly, which includes two support plates 1 arranged opposite each other and connected by a telescopic assembly. The telescopic assembly includes two X-shaped telescopic rods 2, which are respectively located at the top and bottom of the two support plates 1. Each X-shaped telescopic rod 2 includes two telescopic rod units that are bolted together, and the ends of the telescopic rod units are connected to connecting lugs 4 provided on the support plates 1 by connecting bolts 3.

[0018] Furthermore, the end of the wire rope 8 is detachably connected to the support plate 1 via a connecting assembly. The connecting assembly includes a hollow metal connecting rod 10, with metal discs 9 at both ends of the hollow metal connecting rod 10. The end of the wire rope 8 passes through the hollow metal connecting rod 10 and is provided with a rope buckle 11.

[0019] Furthermore, the support plate 1 is provided with a large-diameter pin hole 5 and a small-diameter pin hole 6, which are connected by a transverse connecting hole 7. The diameter of the metal disc 9 is larger than the diameter of the small-diameter pin hole 6 but smaller than the diameter of the large-diameter pin hole 5, and the length of the hollow metal connecting rod 10 is slightly greater than the thickness of the support plate 1. Thus, by inserting and pulling the metal disc 9 into and out of the pin holes on the support plate 1, the connection and disconnection of the wire rope 8 can be achieved, and the length of the wire rope 8 can be adjusted at its end by a rope buckle 11 after passing through the hollow metal connecting rod 10.

[0020] The installation and usage methods of the device in this embodiment are as follows: A. Adjust the length of the wire rope 8 according to the spacing between the lattice columns 12, and thread both ends of the wire rope 8 into the hollow metal connecting rod 10. Set the corresponding number of rope buckles 11 on the part of the wire rope 8 that extends out of the metal disc 9 according to the specifications and safety requirements to ensure that the wire rope 8, the metal disc 9, and the hollow metal connecting rod 10 form a metal end combination. B. Connect the X-type telescopic rod 2 to the support plate 1 using connecting bolts 3, keeping the bolt joints in a loose state, so that the X-type telescopic rod 2 can be freely adjusted; C. After cleaning the concrete or soil inside the lattice column 12, insert the shrinkage support plate 1 into the interior of the lattice column 12 through the gap in the middle of the angle steel of the lattice column. Adjust the angle of the X-shaped telescopic rod 2 according to the actual width of the lattice column 12 so that the support plate 1 can fit tightly against the angle steel on both sides of the lattice column 12. Tighten the connecting bolts 3 so that the support plate 1 can be firmly fixed to the inside of the lattice column 12. At the same time, the large diameter pin hole 5 and the small diameter pin hole 6 are exposed from the gap in the middle of the angle steel on both sides of the lattice column 12. D. Insert the metal end assembly into the large-diameter pin hole 5, ensuring that the two metal discs 9 are respectively attached to the inner and outer sides of the support plate 1, and move them along the transverse connecting hole 7 until the hollow metal connecting rod 10 moves into the small-diameter pin hole 6. At this time, the connection between the wire rope metal end and the support plate is completed. E. Similarly, steel wire ropes 8 are installed in sections between the lattice columns 12 along the direction of personnel passage. If disassembly is required, the above steps are reversed to complete the disassembly and turnover.

[0021] The device in this embodiment is simple and convenient to operate, highly efficient in turnover, safe and reliable. It can effectively realize the fixation and turnover of life ropes between deep foundation pit grid column supports, avoiding the traditional method of fixing life ropes by wrapping them around grid columns, and improving the safety of life rope use and turnover.
