Description

Technical Field

[0001] The invention relates to the technical field of tunnel support, in particular to a steel cable anti-breaking type mining anchor. Background Art

[0002] Anchor cable also refers to steel cable. Its matching anchors and trays are important equipment commonly used in mining projects. They are mainly used to reinforce rocks or soil to ensure the stability of underground tunnels, slopes, tunnels and other structures. They can transmit and distribute the tension in the steel cable. Under the premise of normal use and reasonable design, mining anchors can significantly enhance the tensile capacity of the anchor cable, reduce the risk of anchor cable breakage due to overload, and have a certain anti-breakage effect.

[0003] When supporting the roof of an underground tunnel, first, a steel cable is driven into the roof and the hole where the steel cable is located is grout-fixed, and part of the steel cable is exposed. Then, a tray is mounted on the exposed steel lock to make the tray fit tightly with the roof of the tunnel. An anchor is then installed on the lower side of the tray to fix the position of the tray, so that a stable supporting relationship is formed between the steel cable, the tray and the anchor to support the underground tunnel. However, this installation method is relatively inconvenient in the actual installation process. The existing mining anchors are usually simple in structure. The anchor ring is composed of an anchor ring and a group of multiple clips. This means that when installing the anchor, the worker needs to put the anchor ring on the steel cable with one hand, and use a lot of force to hold the tray to keep its position unchanged, and then use the other hand to put the cone sleeve composed of the clips on the steel cable, and then manually press the clips into the cone sleeve to complete the installation of the anchor. It can be seen from the above that this type of anchor installation method has many operating steps, and the hand exerts a lot of force, which can easily cause hand fatigue and is not conducive to a large number of anchor installations by a single person. Therefore, based on the above problems, a steel cable anti-breakage type mining anchor is proposed. Summary of the invention

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, by providing the shell, the positioning block, the gas transmission part, the transmission part and the clip, the shell can be used as an anchor ring to cooperate with the clip to work together to ensure the effective anchoring of the anchor cable in the rock formation of the top plate of the underground tunnel. The shell as the anchor ring can provide support and fixation, while the clip is responsible for clamping and locking the position of the anchor cable. The anchor installation operation is as follows: first, the anchor cable is driven into the top plate and the hole where the anchor cable is located is grouting and fixed, and part of the anchor cable is exposed to the outside, and then the tray is mounted on the exposed anchor cable. Hold the shell of the fixed module with one hand and put it on the outside of the anchor cable, and lift the tray with the other hand to make the tray fit with the top plate of the tunnel. At this time, move the fixed module upward to make each toggle positioning block contact with the tray. The upward force makes the tray squeeze the folding blocks of each toggle positioning block, so that each folding block rotates with the rotating shaft as the turning point, so that the upper toggle block of each folding block is pressed into the rotating groove, so that the upper end surface of the shell is tightly fitted with the lower end surface of the tray, and the lower extrusion block of each folding block drives the damping pad to rotate out of the rotating groove, so as to position and squeeze the anchor cable passing through the shell. The initial locking of the anchor cable and the rotation of the folding block will press the pressure ring downward, so that the pressure ring is pressed into the bottom end of the ring groove. The downward movement of the pressure ring will drive the pressure plate to press the folded airbag downward, so that the gas in the folded airbag is discharged into the airway through the exhaust pipe, and is sent into the air shell through the transfer of the airway and the intake pipe, and then discharged to the sleeve shell through the exhaust rail pipe. A large amount of external air will push the sleeve shell and the rail block to move obliquely upward with the groove as the guide. The displacement of each rail block will drive each clip to move deep into the tapered hole of the column shell, locking the anchor cable. The cable is clamped and locked to complete the secondary locking of the anchor cable. At the same time, the fixing module fixed on the outside of the anchor cable can fix the upper tray, so that a stable support relationship is formed between the anchor cable, the tray and the fixing module, so that the mining anchor can be installed efficiently and labor-savingly on the lower side of the tray in one step, the tray is fixed, and the anchor cable is clamped and locked, which solves the problem that the existing mining anchor installation method has many installation steps, large hand force, easy to cause hand fatigue, and is not conducive to large-scale installation by one person;

[0015] 2. In the present invention, the anchor cables exposed on the lower side of the fixed module can be enclosed by the combinable protection modules through the use of the provided base ring and protection modules. On the one hand, the exposed anchor cables can be prevented from being corroded and fractured by the external environment. On the other hand, the anchor cables can be prevented from being overloaded and broken due to the underground rock pressure, and shot out from the rock to cause injuries to the workers in the tunnel. The mining anchor can enclose the exposed redundant anchor cables. When the anchor cables break and shoot out from the rock, the enclosure structure can prevent the shot anchor cables from causing injuries to the workers. The problem of redundant anchor cables remaining after the existing mining anchors are installed is solved. When the underground rock pressure increases, causing the anchor cables to be overloaded and broken and shot out from the rock, the sharp head end of the anchor cables can cause injuries to the workers in the tunnel.

[0043] Workflow: The use and installation of mining anchors are as follows. Note 1: Anchor cables 4, anchors, and trays are important equipment commonly used in mining projects. They are mainly used to reinforce rocks or soil to ensure the stability of underground tunnels, slopes, tunnels and other structures. They can transmit and distribute the tension in the steel cable. Under the premise of normal use and reasonable design, mining anchors can significantly enhance the tensile strength of the anchor cable 4, reduce the risk of the anchor cable 4 breaking due to overload, and have a certain anti-break effect; the shell 11 can be used as an anchor ring to work with the clip 15 to ensure the effective anchoring of the anchor cable 4 in the rock layer of the roof of the underground tunnel, where the shell 11 as an anchor ring can provide support and fixing, while the clip 15 is responsible for The anchor 4 is responsible for clamping and locking the position of the anchor cable 4. The anchor installation operation is as follows: first, the anchor cable 4 is driven into the top plate and the hole where the anchor cable 4 is located is grouted and fixed, and part of the anchor cable 4 is exposed to the outside, and then a tray is installed on the exposed anchor cable 4. At this time, one hand holds the shell 11 of the fixing module 1 and puts it on the outside of the anchor cable 4, and the other hand lifts the tray so that the tray fits the top plate of the tunnel. At this time, the fixing module 1 is moved upward to make each toggle positioning block 12 contact with the tray, and the upward force causes the tray to squeeze the folding block 122 of each toggle positioning block 12, so that each folding block 122 rotates with the rotating shaft 121 as the rotating point, so that the upper toggle block of each folding block 122 is pressed into the rotating groove 113, so that the upper end surface of the shell 11 is aligned with the tray. The lower end surface of the plate fits tightly, so that the lower extrusion block of each folding block 122 drives the damping pad 123 to rotate out of the rotating groove 113, and the anchor cable 4 passing through the shell 11 is positioned and squeezed to complete the preliminary locking of the anchor cable 4. At the same time, the rotation of the folding block 122 will press the pressure ring 133 downward, so that the pressure ring 133 is pressed into the bottom end of the annular groove 112. The downward movement of the pressure ring 133 will drive the pressure plate 132 to press the folded airbag 134 downward, so that the gas in the folded airbag 134 is discharged into the airway 115 through the exhaust pipe 135, and is sent into the air shell 141 through the transfer of the airway 115 and the intake pipe 142, and then discharged to the sleeve 148 through the exhaust rail pipe 147, and a large amount of external air will The sleeve 148 and the rail block 149 are pushed to move upward obliquely with the groove 144 as the guide. The displacement of each rail block 149 will drive each clip 15 to move deep into the tapered hole of the column shell 111, clamp and lock the anchor cable 4, and complete the secondary locking of the anchor cable 4. At the same time, the fixing module 1 fixed on the outside of the anchor cable 4 can fix the upper tray, so that a stable supporting relationship is formed between the anchor cable 4, the tray and the fixing module 1. Although the above description is a lot, the actual operation only requires the staff to push up the fixing module 1 to complete the installation, so that the mining anchor can be installed efficiently and labor-savingly on the lower side of the tray in one step, fix the tray, and clamp and lock the anchor cable 4;After the fixing module 1 is installed, the exposed anchor cable 4 can be tensioned with an external tensioning jack as needed, so that the anchor cable 4 generates prestress, thereby improving the stability and bearing capacity of the structure under normal working conditions, and the anchor cable 4 exposed on the lower side of the fixing module 1 can be enclosed by the composable protection module 3. On the one hand, it can prevent the exposed anchor cable 4 from being corroded and fractured by the external environment, and on the other hand, it can prevent the anchor cable 4 from being overloaded and broken due to the rock pressure in the well, and being shot out from the rock formation to cause injuries to the workers in the tunnel. The protection module 3 operates to enclose the exposed anchor cable 4 as follows: first, push the lever 324 of the locking part 32 on both sides to control the displacement of the plug block 323 so that the plug block 323 is out of the slot 118. Due to the loss of the limit of the locking part 32, the splicing shells 31 on both sides can be rotated downward to close the cover. During the closing process, each extrusion member 34 will squeeze and bend the excess anchor cable 4 exposed in the middle, so that the exposed excess anchor The rope 4 can be bent and pressed into the inner side of the shell formed by a group of spliced ​​shells 31, and at the same time, a group of rings 33 and arc shells 36 will also be spliced ​​with the closing operation, so that the complete ring body formed by the splicing of a group of rings 33 can push up against each clip 15, so that the clip 15 can keep clamping and locking the anchor rope 4, and the semicircular shell formed by the splicing of a group of arc shells 36 can be rotated 90 degrees through the track 35 and the track ring 37, so that half of each track ring 37 can enter the track 35 of the spliced ​​shell 31 on the other side, so that the arc shell 36 and the track ring 37 after the splicing and rotation can lock the spliced ​​shell 31 after the cover is closed, completing the protection module 3 to protect the exposed excess anchor rope 4, so that the mining anchor can protect the exposed excess anchor rope 4, and when the anchor rope 4 breaks and shoots out from the rock formation, the enclosure structure can prevent the ejected anchor rope 4 from causing puncture injuries to the staff, and prevent the staff from suffering from serious injuries such as internal organ damage and heavy blood loss. ;
