[0021] Example 1

[0022] See also Figure 1-4The utility model provides the following technical solutions: a prestressed anchor cable guiding device, including an anchor cable fixing column 2, a hollow truncated cone rubber plug 6 is connected to the interior of the anchor cable fixing column 2, an anchor cable placement hole 7 is arranged inside the hollow truncated cone rubber plug 6, a prestressed anchor cable 1 is inserted into the anchor cable placement hole 7, a positioning component 8 is arranged between the prestressed anchor cable 1 and the anchor cable placement hole 7, a moving component 9 is arranged on the positioning component 8, a guide cone head 4 is arranged at one end of the anchor cable fixing column 2, a cylindrical tail pipe 5 is connected to the end of the guide cone head 4 close to the anchor cable fixing column 2, and an external protective component 3 is arranged on the periphery of the cylindrical tail pipe 5.

[0023] Specifically, the external protection component 3 includes a movable cavity 31, a protection cylinder 32, a plug-in groove 33, a plug-in rod 34, a groove 35, a pulling hole 36, a pulling rod 37 and a first spring 38. The outer periphery of the cylindrical tail pipe 5 is provided with a movable cavity 31, the interior of the movable cavity 31 is provided with a protection cylinder 32, the protective cylinder 32 is provided with a groove 35, the interior of the groove 35 is plugged with a plug-in rod 34, a first spring 38 is connected between the groove 35 and the plug-in rod 34, one end of the plug-in rod 34 is connected to a pulling rod 37, a pulling hole 36 is provided on the side wall of the groove 35 and at a position corresponding to the pulling rod 37, and a plug-in groove 33 is provided on the side wall of the cylindrical tail pipe 5 and at a position corresponding to the plug-in rod 34.

[0024] By adopting the above technical solution, the pull rod 37 is pulled to move it outward along the pull hole 36. The movement of the pull rod 37 drives the plug-in rod 34 to move into the groove 35. The plug-in rod 34 moves to squeeze the first spring 38. When the plug-in rod 34 is away from the plug-in slot 33, the protective tube 32 is moved along the moving cavity 31 so that the protective tube 32 covers the periphery of the guide cone head 4. Then the pull rod 37 is released, and the first spring 38 loses the external force and returns to its original appearance, driving the plug-in rod 34 to move and plug into the plug-in slot 33. Under the action of the plug-in rod 34, the protective tube 32 can be plugged and fixed. Under the action of the protective tube 32, the guide cone head 4 can be prevented from colliding with external objects during the movement and transportation process, thereby avoiding damage to surrounding personnel and the guide cone head 4, thereby ensuring the subsequent use effect of the guide cone head 4.

[0025] Specifically, both sides of one end of the plug rod 34 close to the groove 35 are connected to limit sliders, and a limit slide groove is provided on the side wall of the groove 35 at a position corresponding to the limit slider.

[0026] By adopting the above technical solution, the movement of the connecting rod 34 drives the limit slider to move inside the limit slide groove.

Under the action of the protective tube 32, the guide cone head 4 can be prevented from colliding with external objects during the movement and transportation process, thereby preventing damage to surrounding personnel and the guide cone head 4, thereby ensuring the subsequent use effect of the guide cone head 4. After the whole device is moved to the use position, the pull rod 37 is pulled again. The rod 37 moves it outward along the pulling hole 36, and the movement of the pulling rod 37 drives the plug-in rod 34 to move and be received in the groove 35. The plug-in rod 34 moves and squeezes the first spring 38. When the plug-in rod 34 is away from the plug-in groove 33, the protective tube 32 is moved along the moving cavity 31, so that the protective tube 32 is received in the outer periphery of the cylindrical tail pipe 5. Then the pulling rod 37 is released, and the first spring 38 loses the external force and returns to its original state, driving the plug-in rod 34 to move and be plugged into the plug-in groove 33. Under the action of the plug-in rod 34, the protective tube 32 can be plugged and fixed to prevent the protective tube 32 from affecting the use effect of the guide cone head 4, and then the guide cone head 4 is plugged into the rock slope, and then the prestressed anchor cable 1 to be used is plugged into the anchor cable placement hole 7. Under the action of the anchor cable fixing column 2 and the hollow truncated cone rubber plug 6, a guiding effect is provided for the plug-in of the prestressed anchor cable 1 to prevent the prestressed anchor cable 1 from tilting and affecting the use effect of the prestressed anchor cable 1.

Under the action of the protective tube 32, the guide cone head 4 can be prevented from colliding with external objects during the movement and transportation process, thereby preventing damage to surrounding personnel and the guide cone head 4, and ensuring the subsequent use effect of the guide cone head 4. After the entire device is moved to the use position, the pull rod 37 is pulled to move it outward along the pull hole 36. The movement of the pull rod 37 drives the plug rod 34 to move and be collected into the groove 35. The plug rod 34 moves to squeeze the first spring 38. When the plug rod 34 is away from the plug groove 33, the protective tube 32 is moved along the moving cavity 31, so that The protective tube 32 is retracted into the periphery of the cylindrical tail pipe 5, and then the pull rod 37 is loosened. The first spring 38 loses the external force and returns to its original state, driving the plug-in rod 34 to move and plug into the plug-in slot 33. Under the action of the plug-in rod 34, the protective tube 32 can be plugged and fixed to prevent the protective tube 32 from affecting the use effect of the guide cone head 4.
