Description

Technical Field

[0001] The utility model belongs to the technical field of mining equipment and relates to a grouting device for mine support. Background Art

[0002] In mining, it is necessary to build a supporting structure. After the support is built, cement mortar needs to be injected into the inside, so the corresponding grouting device is needed.

[0003] The existing grouting device injects cement mortar into the interior through a grouting truck. Generally, a relatively deep grouting hole is drilled in the mine, and a grouting pipe is lowered into the hole. However, during the grouting process, bubbles and other voids are generated inside the hole, thereby reducing the strength of the grouting column. To eliminate this situation, an oscillating device is needed to vibrate the slurry. However, the common oscillating devices currently place the oscillating devices inside the slurry through a long rod after the grouting is completed, which is very troublesome to operate. Therefore, a grouting device for mine support is proposed to solve the above problem. Utility Model Content

[0017] The utility model is described in detail below with reference to the accompanying drawings:

[0018] like Figure 1 As shown, a grouting device for mine support includes a grouting pipe 1, which is an existing conventional grouting pipe 1, and is used to inject grout into the grouting hole of the mine. A vibration pipe 2 with a blocking structure at both ends is provided on one side of the grouting pipe 1. The vibration pipe 2 and the grouting pipe 1 are arranged in parallel with each other. The vibration pipe 2 can vibrate the cement mortar evenly during grouting. Specifically, a connecting rod 3 is fixed on one side of the grouting pipe 1, and the connecting rod 3 is connected to the vibration pipe 2. A rotating shaft 4 is provided in the vibration pipe 3, and the rotating shaft 4 is located in the middle of the vibration pipe 2. The rotating shaft 4 is along the diameter of the grouting pipe 1. The rotating shaft 4 is arranged in a direction, one end of the rotating shaft 4 is connected to a transmission rod 5 which is arranged perpendicular to the rotating shaft 4, the end of the rotating shaft 4 away from the transmission rod 5 is connected to a motor 6 for driving the rotating shaft 4 to rotate, the motor 6 is fixed to the inner wall of the vibration tube 2, the motor 6 can be a micro motor, the transmission rod 5 is hinged with a vibration rod 7 at one end away from the rotating shaft 4, the transmission rod 5 can drive the vibration rod 7 to rotate, and the vibration rod 7 can hit the inner wall of the vibration tube 2 when it rotates, so that the vibration tube 2 vibrates, in order to improve the hitting effect, the vibration rod 7 is fixed with a vibration hammer 8 at one end away from the transmission rod 5.
