Description

Technical Field

[0001] The invention relates to the technical field of anchor cable devices, and in particular to an intelligent early warning anchor cable device for side (land) slopes. Background Art

[0002] Prestressed anchor cable protection uses cement mortar of a certain strength to form an anchor body with a certain strength at the bottom of the anchor hole at an effective depth with the surrounding rocks. Then, under the prestressed action of the anchor cable, the unstable mountain part is firmly connected to the stable mountain to form a whole, ensuring the stability of the slope and preventing the structural cracks from developing further, thereby achieving the purpose of protection. Prestressed anchor cables can, on the one hand, directly generate anti-slip resistance on the sliding surface, and on the other hand, increase the anti-slip friction resistance by increasing the positive stress on the sliding surface, thereby improving the integrity and stability of the slope rock and soil.

[0003] However, most of the existing anchor slope anchor devices do not have the function of intelligent early warning when in use, and cannot perform real-time detection of the tension that the anchor can withstand, and the protective safety performance is low. At the same time, during the installation of the anchor chain, most of them are connected to the anchor device by sliding, and the pre-tightening process is time-consuming and labor-intensive, and the installation is inconvenient. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the present invention proposes an intelligent early warning anchor cable device for side (slip) slopes, which solves the problems that the existing anchor cable side slope anchor cable devices do not have the intelligent early warning function when in use, cannot perform real-time detection of the tension that the anchor cable can withstand, have low protective safety performance, and are mostly slidably connected to the anchor cable device during the installation process of the anchor chain, which is time-consuming and labor-intensive during the pre-tightening process and inconvenient to install. The present invention also provides an intelligent early warning anchor cable method for side (slip) slopes.

[0005] The present invention is achieved through the following technical scheme: an intelligent early warning anchor cable device for side (landing) slopes, comprising a pre-buried head, an anchor chain fixing column, and a pressure sensor. The pre-buried head is pre-buried inside a precast concrete layer, a detection flange is arranged above the pre-buried head, the detection flange is ball-jointed with the pre-buried head, a pressure sensor is arranged between the detection flange and the precast concrete layer, the detection flange is fixedly connected to the anchor chain fixing column, a plurality of limit flanges are installed at the lower part of the anchor chain fixing column, bearings are installed between the limit flanges, and a through hole for passing the anchor chain is arranged at the upper part of the anchor chain fixing column.

[0006] Furthermore, the anchor chain fixing column includes an anchor chain fixing column 1 and an anchor chain fixing column 2, the anchor chain fixing column 1 is fixedly connected to the anchor chain fixing column 2, a plurality of limiting flanges are installed on the anchor chain fixing column 1, bearings are installed between the limiting flanges, and a through hole for passing the anchor chain is provided on the anchor chain fixing column 2.

[0008] Furthermore, the intelligent early warning device includes a processing chip disposed inside the intelligent early warning device and an alarm disposed on one side of the processing chip, and the alarm is connected to the intelligent early warning device by screws. In this way, when the data detected by the pressure sensor is greater than a preset value, information can be fed back to the processing chip, and instructions can be sent to the alarm through the processing chip, and an alarm can be sounded through the alarm, thereby achieving the purpose of safety protection.

[0009] Furthermore, the number of the limiting flanges is three, the number of the bearings is two, and the bearings are interference-connected with the anchor chain fixing column. The limiting flanges can play a limiting role when tying the anchor chain to prevent the anchor chain from moving up and down. The bearings can convert the original sliding friction into rolling friction when tying the anchor chain, so that the anchor chain can be tightened and fixed conveniently and quickly, and the operation is convenient.

[0010] Furthermore, the anchor chain fixing column 2 is formed with the through hole 1, the through hole 2 is formed above the through hole 1, and the through hole 3 is formed above the through hole 2. The through hole 1, the through hole 2 and the through hole 3 can withstand a certain tensile stress when the anchor chain is bypassed, thereby reducing the locking load of the locking screw and playing a role in safety protection.

[0011] Furthermore, a locking screw is threadedly connected to the top of the anchor chain fixing column 2, and the anchor chain can be fixed by the locking screw.

[0012] Furthermore, the anchor chain is wound around the bearing and passes through the first through hole, the second through hole and the third through hole in an S shape.

[0013] The invention discloses an intelligent early warning anchor cable method for side (slip) slopes. Based on an intelligent early warning anchor cable device for side (slip) slopes, a pre-embedded head is pre-embedded in a precast concrete layer, and then after the anchor chain is passed around the bearing between the limit flanges, one end of the anchor chain is tightened, and the anchor chain is tied tightly by means of iron wire. When the anchor chain is tied, it is indirectly tightened on the anchor chain fixing column through the bearing, and the original sliding friction force is converted into rolling friction force, so as to avoid wear between the anchor chain and the anchor chain fixing column, and the anchor chain is tightened and fixed conveniently and quickly; at the same time, the anchor chain is passed around through hole one, through hole two and through hole three in an S shape, and then the anchor chain is fixed tightly by means of locking screws. During the working process, a pressure sensor under the detection flange detects the change of the tension borne by the anchor chain on the anchor chain fixing column in real time, and then feeds back the information to a processing chip. When the data detected by the pressure sensor is greater than a preset value, an instruction is sent to an alarm through the processing chip, and an alarm is given through the alarm.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1.

The anchor chain fixing column 1 7 and the anchor chain fixing column 2 2 are actually formed in one piece, and here it is just convenient to distinguish the positions for installing the bearing 9 and setting the through hole. A pressure sensor 4 is arranged between the detection flange 3 and the precast concrete layer 1, and the pressure sensor 4 is arranged in a cross-shaped manner. The tension changes borne by the anchor chains on the anchor chain fixing column 1 7 and the anchor chain fixing column 2 10 can be detected in real time by the pressure sensor 4.

[0027] A connecting line 5 is provided on one side of the pressure sensor 4 , and an intelligent early warning device 6 is provided on one end of the connecting line 5 . The intelligent early warning device 6 is connected to the pressure sensor 4 via the connecting line 5 , and can receive the tension change data detected by the pressure sensor 4 in real time.
