Description

Technical Field

[0001] The utility model relates to the technical field of process rods, in particular to a new rock drilling process rod. Background Art

[0002] Rock drilling rods can be used for drilling rock anchor holes, anchor holes, blasting holes, grouting holes and other drilling construction in railway, highway, river, hydropower construction and other projects; the specifications and models of the rock drilling rod body are often based on the actual needs of the site, and the length ranges from a few hundred millimeters to several thousand millimeters. The diameter and connection method of the rod body are also different. The common external shapes of rock drilling rods are hexagonal and round, and the most common connection method is threaded connection;

[0003] However, after two process rods are connected by threaded connection, the two adjacent process rods often become loose when the process rods rotate forward and backward, resulting in certain troubles in actual use. Therefore, we propose a new rock drilling process rod to solve the above-mentioned problems. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that after two process rods are connected by threaded connection, two adjacent process rods often become loose when the process rods rotate forward and backward, and proposes a new rock drilling process rod.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A new rock drilling rod comprises a rod body, and the rod further comprises:

[0007] The inner joint and the outer joint are respectively fixedly mounted at the two ends of the rod body, and the inner joint and the outer joint are used for plug-in matching when two process rod bodies are connected;

[0008] A retaining ring, wherein the retaining ring is fixedly sleeved on the inner joint;

[0009] The clamping mechanism is sleeved on the external joint and is used for clamping with the corresponding retaining ring when two process rod bodies are connected.

[0010] In a possible design, the rod body is a hollow structure, a plurality of drainage holes are symmetrically opened on the inner wall of the rod body, and a protective net is fixedly installed in the drainage hole.

[0011] In a possible design, the clamping mechanism includes a plurality of clamping assemblies arranged at equal intervals on the external joint, and the plurality of clamping assemblies are clamped with corresponding retaining rings. A gear assembly is installed on the external joint, and the gear assembly is respectively connected to the plurality of clamping assemblies.

[0012] In a possible design, the snap assembly includes a support plate fixedly mounted on the external joint, a rotating shaft passing through the support plate and rotatably connected, an arc-shaped baffle plate is fixedly mounted on one end of the rotating shaft, the arc-shaped baffle plate is clamped with a corresponding baffle ring, and the rotating shaft is connected to the gear assembly.

[0013] In a possible design, a torsion spring is sleeved on the rotating shaft, and two ends of the torsion spring are respectively fixedly connected to one side of the arc-shaped baffle plate and one side of the support plate.

[0014] In one possible design, the gear assembly includes a gear ring rotatably mounted on an external joint, a gear is fixedly mounted on the other end of the rotating shaft, multiple gears are meshed with the gear ring, a threaded tube is fixedly mounted on one side of the gear ring, a fixing plate is fixedly mounted on the external joint, a screw rod passes through the fixing plate, and the screw rod is movably threadedly connected to the threaded tube.

[0015] In a possible design, a plurality of anti-slip rings are provided on the fixing sleeve at equal intervals on the inner joint, and an inclined chamfer is provided on the outer edge of the anti-slip ring.

[0016] In the present application, when the two process rod bodies are clamped, the inner joint is first inserted into the corresponding outer joint, and multiple anti-slip rings can be used to fit tightly with the inner wall of the outer joint to prevent the inner joint and the outer joint from shaking. Then, the gear ring can be rotated to engage with the multiple gears for transmission, which can drive the multiple shafts to rotate, thereby driving the multiple arc-shaped baffles to move. After the arc-shaped baffles and the baffle ring form a clamping relationship, the threaded tube can be moved to a position corresponding to the screw rod, so that the screw rod and the threaded tube can be threadedly connected to the gear ring, thereby braking the multiple arc-shaped baffles. When the arc-shaped baffle rotates, torsion can be applied to the torsion spring, so that the torsion spring has elastic potential energy. When the two process rod bodies are disassembled, the connection between the threaded tube and the screw rod can be released, and the multiple arc-shaped baffles can be driven to rotate in the opposite direction under the action of the elastic potential energy of the multiple torsion springs, so that the arc-shaped baffles and the baffle ring are disengaged, and then the inner joint can be pulled out of the outer joint.

[0017] In the utility model, the new rock drilling process rod can drive multiple buckle components to move by starting the gear component through the clamping mechanism, so that after the two process rod bodies are plugged in and matched, they can be clamped and matched with the corresponding retaining ring to achieve a stable connection between the two process rod bodies;

[0019] The utility model can realize stable connection of the two process rod bodies by driving the clamping mechanism after the two process rod bodies are plugged in and matched, thereby preventing the process rods from loosening when excavating rock, and thus has good practicality.
