Description

Technical Field

[0001] The present application relates to the technical field of anchor support, and in particular to a quick fastening device for a resin anchor. Background Art

[0002] High-pressure air is used as the power source of the air-leg rock drill in underground mines, which can reinforce and support high-risk tunnels such as faults, crushing, rock bursts, and mud layers, including but not limited to support operations using anchor cables and resin anchors. The resin anchor is placed at the front end of the anchor. During the installation of the anchor, the resin is pressurized and stirred and squeezed so that the resin anchor is filled with the spiral wire. The anchor and the spiral wire work together to anchor.

[0003] When using an air-leg rock drill to perform resin anchor support operations, after drilling is completed, the anchoring agent and resin anchor (including anchor sheet) are successively loaded into the borehole, and then the nut of the resin anchor is tightened by the air-leg rock drill. Since the anchoring agent and resin will react thermally during the curing process and generate heat, the heat will not be effectively dissipated, which will cause the temperature of the resin anchor nut to rise, and even cause the nut to expand and deform. This may cause the thread size at the tail of the resin anchor to no longer match the nut, making it impossible to effectively tighten the nut, making it difficult to ensure the quality of the support process. Utility Model Content

[0004] In order to solve or partially solve the problems existing in the related technology, the present application provides a resin anchor rod quick fastening device, which is arranged on a pneumatic leg rock drill. During the fastening process, the resin anchor rod nut will be cooled through the cooling water hole, and the threaded end of the resin anchor rod will be limited through the cavity.

[0005] The first aspect of the present application provides a resin anchor quick fastening device, which is an integrated structure and includes: a fastening sleeve section, a circular cavity section and a connecting section. The fastening sleeve section is arranged at the front end of the fastening device, and the fastening sleeve section is sleeved on the nut of the resin anchor. A circular cavity section is arranged at the rear side of the fastening sleeve section. The circular cavity section is matched with the threaded end of the resin anchor and is used to limit the threaded end. The connecting section is arranged at the rear side of the circular cavity section. A cooling water hole is opened in the circular cavity section. The cooling water hole passes through the connecting section and is connected with the circular cavity section. The cooling water hole is used to insert a water needle of an air-leg rock drill.

[0006] Furthermore, the connecting section is also provided with a buckle, which is arranged in the middle of the connecting section and is used for connecting with the air-leg rock drill.

[0007] Furthermore, the fastening sleeve is a hexagon socket sleeve.

[0008] Furthermore, the connecting section is an outer hexagonal structure.

[0009] The technical solution provided by this application may have the following beneficial effects:

[0010] The present application provides a resin anchor rod quick fastening device, which effectively cools down the resin anchor rod nut during the fastening process, reduces the thermal expansion and contraction effect by lowering the temperature of the resin anchor rod and the fastening device, avoids deformation of the nut, effectively improves the fastening quality, and ensures that the nut can be correctly inserted and fastened; at the same time, the threaded end of the resin anchor rod is limited by a circular cavity, further improving the fastening efficiency. The device enables the resin anchor rod nut to be effectively fastened, maintains the dimensional stability of the nut and the fastening device, and ensures the quality and reliability of the fastening operation.

[0021] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0022] The resin anchor bolt quick fastening device shown in the figure is an integrated structure, comprising: a fastening sleeve section 1, a circular cavity section 2 and a connecting section 4. The front end of the fastening device is connected to the nut of the resin anchor bolt, and the rear end is connected to the air leg type rock drill to assist the air leg type rock drill in tightening the nut.

[0023] The fastening sleeve section 1 is arranged at the front end of the fastening device, and the fastening sleeve section 1 is sleeved on the nut of the resin anchor rod. The fastening sleeve is a hexagonal sleeve fastening sleeve matched with the nut, which can limit the nut and drive the nut to rotate and tighten.

[0024] A circular cavity section 2 is set on the rear side of the tightening sleeve section 1. The circular cavity section 2 is matched with the threaded end of the resin anchor rod and is used to limit the threaded end. When in use, the threaded end extends into the circular cavity and is limited by the cavity to prevent the screw from deviating during the rotation of the nut and affecting the connection effect.

[0025] The connecting section 4 is arranged at the rear side of the circular cavity section 2 and is an outer hexagonal structure. The connecting section 4 is provided with a cooling water hole. The cooling water hole 5 penetrates the connecting section 4 and is connected with the circular cavity section 2. The cooling water hole 5 is used to insert the water needle of the air-leg rock drill, so that when the device is connected to the air-leg rock drill, the cooling water enters the inside of the device through the cooling water hole 5 to cool the anchor rod end and the nut. In order to further improve the stable connection between the fastening device and the air-leg rock drill, the connecting section 4 is also provided with a buckle 3, which is arranged in the middle of the connecting section 4, and the device is clamped on the air-leg rock drill through the buckle 3.

[0026] During the resin anchor support operation using the air-leg rock drill, after the drilling is completed, the anchoring agent and the resin anchor (including the anchor sheet) are successively loaded into the drill hole, and then the fastening device is installed on the air-leg rock drill so that the water needle of the air-leg rock drill is inserted into the cooling water hole 5, and then the nut of the resin anchor is fastened. The fastening device used has a circular cavity with a capacity of the cooling water hole 5 and the threaded end of the resin anchor. During the fastening process, water flows from the cooling water hole 5 into the fastening sleeve section 1 to cool the nut, and at the same time, the threaded end of the resin anchor is extended into the circular cavity to limit the position, so that the resin anchor nut can be effectively fastened, and the resin anchor nut will not be deformed.
