Description

Technical Field

[0001] This utility model relates to the field of grouting anchor technology, and in particular to a hollow grouting locking anchor. Background Technology

[0002] When hollow grouting anchors are used to grout the connection gaps of a designated rock wall or wall through grouting pipes, if the gravel or mud inside the rock wall or wall becomes loose and unstable, the gravel and mud will accumulate and block the grout outlet on the outside of the hollow grouting anchor during grouting, thus blocking the grouting process from the outlet.

[0003] The existing announcement number CN218716895U discloses a hollow grouting anchor rod for preventing grout blockage, including a hollow steel strand, an anchor plate, a push tube, a grout outlet, and an end lock. An anchor plate is sleeved on the outer side of one end of the hollow steel strand, and a tray is sleeved on the side of the hollow steel strand near the anchor plate. The push tube is sleeved on the side of the hollow steel strand near the concave surface of the tray. This hollow grouting anchor rod for preventing grout blockage has a mesh structure formed by front and side steel bars at the circular grout outlet on the outer side of the grouting pipe, with the opening smaller than the diameter of the grout outlet. The anti-blocking mechanism of the mesh structure can block large stones from entering the internal space of the anti-blocking mechanism, ensuring that the hollow grouting anchor rod has the effect of preventing grout blockage. Two sets of symmetrically distributed support drums are inserted into the gaps on both sides of the middle of the hollow steel strand, so that the gaps on both sides of the hollow steel strand are continuously open, which facilitates rapid grouting at the connection position of the hollow grouting anchor rod.

[0004] However, when the hollow grouting anchor bolts mentioned above are used to prevent grout blockage, the mesh structure at the front prevents large stones from blocking the grout, making it difficult to adjust the mesh structure and easily leading to poor grout discharge. Utility Model Content

[0005] The purpose of this utility model is to provide a hollow grouting locking anchor rod, which solves the problem that when using a hollow grouting anchor rod to prevent grout blockage, the mesh structure at the front prevents large particles of stone from blocking the grout, making it difficult to adjust the mesh structure and easily leading to poor grout discharge effect.

[0006] To achieve the above objectives, this utility model provides a hollow grouting locking anchor bolt, comprising a grouting pipe, an adjusting component, a supporting component, and a fixing component. The adjusting component includes an adjusting threaded pipe, supporting reinforcing bars, a guide head, and an adjusting nut. The adjusting threaded pipe is slidably connected to the grouting pipe and passes through the grouting pipe. There are multiple supporting reinforcing bars, each of which is fixedly connected to the adjusting threaded pipe and located at the bottom of the adjusting threaded pipe. The guide head is fixedly connected to the supporting reinforcing bars and located at the bottom of the supporting reinforcing bars. The adjusting nut is threadedly connected to the adjusting threaded pipe and located on the outside of the adjusting threaded pipe. The supporting component and the fixing component are connected to the grouting pipe.

[0007] The adjustment assembly further includes partition rods and limiting tubes. There are multiple partition rods, each fixedly connected to the guide head and located at the top of the guide head. There are also multiple limiting tubes, each fixedly connected to the partition rods and located at the top of the partition rods.

[0008] The support assembly includes a partition and a limiting seat. The partition is fixedly connected to the adjusting nut and is located at the bottom of the adjusting nut. The limiting seat is fixedly connected to the partition and is located between the partition and the limiting tube.

[0009] The side of the grouting pipe is provided with multiple fixing holes.

[0010] The fixing component includes a fixing screw and a fixing nut. The fixing screw is detachably connected to the grouting pipe and passes through the fixing hole. The fixing nut is threadedly connected to the fixing screw and is located on the outside of the grouting pipe.

[0011] This utility model discloses a hollow grouting locking anchor rod. The grouting pipe connects to an external grouting machine for easy grouting of the locking anchor rod structure. The adjusting threaded pipe provides support for the supporting steel bars. The supporting steel bars and the guide head provide support for the rock wall or wall. The adjusting threaded pipe cooperates with the adjusting nut to facilitate adjustment of the distance between the partition and the guide head. When grouting different materials, the locking anchor rod is inserted into the anchor hole, and the adjusting nut is rotated to increase the distance between the partitions, which facilitates adjustment of the grouting speed for different materials. This makes the grouting of the anchor rod faster and more efficient. It solves the problem that when using a hollow grouting anchor rod to prevent grout blockage, the front mesh structure prevents large stones from blocking the grout, making it difficult to adjust the mesh structure and easily leading to poor grouting effect.

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] The first embodiment of this application is as follows:

[0020] Please see Figures 1 to 4 ,in, Figure 1 This is a schematic diagram of the overall structure of the hollow grouting locking anchor rod according to the first embodiment of this utility model. Figure 2 This is a schematic diagram of the structure of the adjustment component according to the first embodiment of this utility model. Figure 3 This is a structural schematic diagram of the support component according to the first embodiment of this utility model. Figure 4This is a schematic diagram of the fixing component of the first embodiment of the present invention. The present invention provides a hollow grouting locking anchor rod, including a grouting pipe 101, an adjusting component, a supporting component, and a fixing component. The adjusting component includes an adjusting threaded pipe 102, a supporting steel bar 103, a guide head 104, an adjusting nut 105, a partition rod 106, and a limiting pipe 107. The supporting component includes a partition plate 108 and a limiting seat 109. The fixing component includes a fixing screw 111 and a fixing nut 112. The aforementioned solution solves the problem that when using a hollow grouting anchor rod to prevent grout blockage, the mesh structure at the front prevents large particles of stone from blocking the grout, making it difficult to adjust the mesh structure and easily leading to poor grout discharge.

[0021] In this specific embodiment, the adjusting threaded pipe 102 is slidably connected to the grouting pipe 101 and passes through the grouting pipe 101. Multiple supporting reinforcing bars 103 are present, each fixedly connected to the adjusting threaded pipe 102 and located at its bottom. The guide head 104 is fixedly connected to the supporting reinforcing bars 103 and located at their bottom. The adjusting nut 105 is threadedly connected to the adjusting threaded pipe 102 and located outside the adjusting threaded pipe 102. The supporting assembly and the fixing assembly are connected to the grouting pipe 101. 1. It connects to an external grouting machine to facilitate grouting of the lock-lock anchor structure. The adjusting threaded pipe 102 provides support for the supporting steel bar 103. The supporting steel bar 103 and the guide head 104 are used to provide support for the rock wall or wall. The adjusting threaded pipe 102 cooperates with the adjusting nut 105 to facilitate the adjustment of the distance between the partition plate 108 and the guide head 104. When grouting different materials, the lock-lock anchor is inserted into the anchor hole, and the adjusting nut 105 is rotated to increase the distance between the partition bars 106, which facilitates the adjustment of the grouting speed for different materials, making the grouting of the anchor faster and more efficient.

[0022] The system comprises multiple partition rods 106, each fixedly connected to a guide head 104 and positioned at the top of the guide head 104. Multiple limiting tubes 107 are also fixedly connected to the partition rods 106 and positioned at the top of the partition rods 106. The partition rods 106 are made of elastic material to prevent large stones from blocking the grouting openings between the supporting reinforcing bars 103. The limiting tubes 107 cooperate with the limiting seats 109 to fix the top position of the partition rods 106. When the adjusting nut 105 is rotated, the adjusting threaded tube 102 moves up and down inside the adjusting nut 105, simultaneously moving the supporting reinforcing bars 103 and the guide head 104, facilitating adjustment of the distance between the guide head 104 and the partition plate 108.

[0023] Secondly, the partition 108 is fixedly connected to the adjusting nut 105 and is located at the bottom of the adjusting nut 105. The limiting seat 109 is fixedly connected to the partition 108 and is located between the partition 108 and the limiting tube 107. The partition 108 is used to limit and support the position of the entire locking anchor rod. The limiting seat 109 is used to adjust the position of the limiting tube 107 and the partition rod 106 to prevent the partition rod 106 and the limiting tube 107 from shifting.

[0024] Furthermore, the side of the grouting pipe 101 is provided with a plurality of fixing holes 110, which cooperate with the fixing nut 112 to facilitate fixing the position of the adjusting threaded pipe 102.

[0025] Finally, the fixing screw 111 is detached from the grouting pipe 101 and passes through the fixing hole 110. The fixing nut 112 is threadedly connected to the fixing screw 111 and is located on the outside of the grouting pipe 101. When adjusting the position of the adjusting threaded pipe 102, the fixing screw 111 is pulled out from the inside of the grouting pipe 101 to facilitate the adjustment of the position of the adjusting threaded pipe 102. After the adjustment is completed, the fixing screw 111 is inserted into the fixing hole 110, and then the fixing screw 111 is locked by the fixing nut 112 to facilitate the fixation of the position of the adjusting threaded pipe 102.

[0026] Using the hollow grouting locking anchor bolt of this embodiment, the grouting pipe 101 is connected to an external grouting machine to facilitate grouting of the locking anchor bolt structure. The adjusting threaded pipe 102 provides support for the supporting steel bar 103. The supporting steel bar 103 and the guide head 104 are used to provide support for the rock wall or wall. The adjusting threaded pipe 102 cooperates with the adjusting nut 105 to facilitate adjustment of the distance between the partition plate 108 and the guide head 104. When grouting different materials, the locking anchor bolt is inserted into the anchor hole, and the adjusting nut 105 is rotated to increase the distance between the partition rods 106, which facilitates adjustment of the grouting speed for different materials, making the grouting of the anchor bolt faster and more efficient. This solves the problem that when using a hollow grouting anchor bolt to prevent grout blockage, the mesh structure at the front prevents large particles of stone from blocking the grout, making it difficult to adjust the mesh structure and easily leading to poor grouting effect.

[0027] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application.
