Description

Technical Field

[0001] The utility model relates to the technical field of tunnel anchor rod and cable support, in particular to a tunnel anchor rod and cable support reinforcement device. Background Art

[0002] Tunnels are various passages drilled between the surface and the ore body, used for ore transportation, ventilation, drainage, pedestrians, and various necessary preparatory works for the new excavation of ore for metallurgical equipment. These passages are collectively referred to as tunnels. The effective control of the deformation of the surrounding rock of coal mine tunnels is the prerequisite for ensuring the safe production of coal mines. At present, the U-shaped shed combined with deep and shallow hole grouting and anchor (rod) support is more commonly used in deep well tunnels of coal mines to achieve the control of surrounding rock deformation, and the effect is quite obvious. However, when installing the anchor rod and anchor cable support in the tunnel, due to the poor initial fixing effect, it is easy to affect the later use effect. Therefore, a tunnel anchor rod and anchor cable support reinforcement equipment is needed.

[0003] Chinese patent CN208534512U discloses a support structure for a deep well soft rock tunnel, which relates to the field of tunnel support, including conventional anchor rods, hollow grouting anchor rods, conventional anchor cables, and hollow grouting anchor cables; the tunnel adopts a straight-wall semicircular arch tunnel, and the conventional anchor rods, hollow grouting anchor rods, conventional anchor cables, and hollow grouting anchor cables are arranged at intervals on the top and both sides of the tunnel; the spacing of the conventional anchor rods is 750-850mm, and the row spacing is 750-850mm; the spacing of the hollow grouting anchor rods is 2250-2550mm, and the row spacing is 2250-2550mm, the spacing of the conventional anchor cables is 1150-1250mm, and the row spacing is 750-850mm, the spacing of the hollow grouting anchor cables is 2250-2550mm, and the row spacing is 2250-2550mm. This patent meets the support requirements of deep well soft rock tunnels and improves the service life of soft rock tunnels. However, this patent does not reinforce the support in the early stage of tunnel installation, which can easily reduce the use effect of the support in the later use process. Utility Model Content

The fixing assembly 5 includes a mounting plate 51, and each mounting plate 51 is rotatably connected inside the U-shaped groove 4. A fixing bolt 52 is threadedly connected inside each mounting plate 51, and one end of each fixing bolt 52 extends into the inside of the surrounding rock 1. A plurality of clamping blocks 53 are fixedly connected to the outside of each mounting plate 51, and the outside of each clamping block 53 contacts the inside of the surrounding rock 1. When in use, the fixing plate 3 is mounted on the U-shaped steel frame 21 through the fixing assembly 5 for reinforcement. First, a clamping groove used for the clamping block 53 is opened on the surrounding rock 1, and then the mounting plate 51 is rotated in the U-shaped groove 4 so that the mounting plate 51 is rotated in the direction of the surrounding rock 1. At this time, the clamping block 53 on the mounting plate 51 will be stuck in the opened clamping groove, and then, a tool is used to drive the fixing bolt 52 into the inside of the surrounding rock 1 to fix the mounting plate 51.

[0023] Furthermore, the fastening assembly 7 includes a threaded cylinder 71, each of which is fixedly connected to the inside of the fixing plate 3, a threaded rod 72 is threadedly connected to the inside of each threaded cylinder 71, and one end of each threaded rod 72 is threadedly connected to a connecting cylinder 73, the two fixing plates 3 are fixedly connected to the inside of the air intake pipe 75, the two air intake pipes 75 are provided with sealing plugs 76, and one end of the two air intake pipes 75 is fixedly connected to an air bag 74, and the reinforcement assembly 6 includes a reinforcement plate 61, the two reinforcement plates 61 are fixedly connected to the side of the connecting cylinder 73 away from the threaded rod 72, and the side of the two air bags 74 away from the air intake pipe 75 is fixedly connected to the outside of the reinforcement plate 61, and the outside of the two reinforcement plates 61 is provided with a toothed surface 62. When the mounting plate 51 is fixed, the threaded rod 72 is rotated forward in the threaded cylinder 71. When the threaded rod 72 rotates, it will pass through the threaded rod 7 The thread on the outside of the threaded tube 71 cooperates with the thread on the temporal part of the threaded tube 71, so that the threaded rod 72 extends into the threaded tube 71. At this time, through the cooperation between the thread on the outside of the threaded rod 72 and the thread inside the connecting tube 73, when the threaded rod 72 moves into the threaded tube 71, it will drive the reinforcing plate 61 to approach the U-shaped steel frame 21, so that the tooth surface 62 on the reinforcing plate 61 contacts the outside of the U-shaped steel frame 21. Subsequently, air is pumped into the airbag 74 through the air intake pipe 75, so that the airbag 74 begins to expand, thereby reinforcing the fixation of the reinforcing plate 61.

[0024] In summary: when in use, the fixing plate 3 is installed on the U-shaped steel frame 21 through the fixing assembly 5 for reinforcement. First, a slot for the block 53 is opened on the surrounding rock 1, and then the mounting plate 51 is rotated in the U-shaped slot 4 to rotate the mounting plate 51 in the direction of the surrounding rock 1. At this time, the block 53 on the mounting plate 51 will be stuck in the opened slot. Subsequently, a tool is used to drive the fixing bolt 52 into the interior of the surrounding rock 1 to fix the mounting plate 51. After the mounting plate 51 is fixed, the threaded rod 72 is rotated forward in the threaded tube 71. When the threaded rod 72 rotates, the threaded rod 72 will extend to the interior of the threaded tube 71 through the cooperation of the thread on the outside of the threaded rod 72 and the thread on the temporal part of the threaded tube 71. At this time, the threaded rod The outer threads of 72 cooperate with the inner threads of the connecting tube 73. When the threaded rod 72 moves into the threaded tube 71, it will drive the reinforcement plate 61 toward the U-shaped steel frame 21, so that the tooth surface 62 on the reinforcement plate 61 contacts the outside of the U-shaped steel frame 21. Subsequently, air is pumped into the air bag 74 through the air intake pipe 75 to make the air bag 74 begin to expand, thereby reinforcing the fixation of the reinforcement plate 61. Therefore, through the cooperation of the fixing plate 3 and the fixing component 5, the fastening component 7 and the reinforcement component 6, the U-shaped steel frame 21 is reinforced in the early stage, so as to avoid the U-shaped steel frame 21 from falling off and becoming unstable in the later use, thereby enhancing the later use effect and stability effect of the U-shaped steel frame 21 and improving practicality.
