However, small drill rods are still mostly connected manually, and the connection process is very laborious. The existing invention patent number is CN103711446B, a drill rod unscrewing mechanism, including a front clamping body and a rear clamping body installed on a fixed bracket, the front clamping body and the rear clamping body include a relatively arranged positioning clamping mechanism and a clamping actuator on both sides of the clamping center line, and the fixed bracket includes a first fixed bracket and a second fixed bracket; the front clamping body is installed in the first fixed bracket through a rear fixed shaft, and the rear clamping body is installed in the flip bracket of the second fixed bracket through a rear fixed shaft, and the rear lower end of the flip bracket is hinged to the front end of the piston of the flip cylinder.

[0003] The prior art has the following technical defects:

[0004] The above technical solution can realize the connection and disassembly of the drill rod and ensure the convenient loading and unloading of the center axis, but the drill rod needs to be inserted into the clamp assembly during loading and unloading, which is inconvenient and can only be processed on a horizontal ground. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a drill rod self-unloading clamp.

[0006] The drill rod self-unloading clamp described in the utility model comprises a slide, a first fixed frame and a second fixed frame are fixedly connected on the slide, a first drill rod frame is provided on the first fixed frame, an arc guide rail is provided on the second fixed frame, a rotating bracket matched with the arc guide rail is hinged on the second fixed frame, a second drill rod frame is provided on the rotating bracket, the first drill rod frame and the second drill rod frame are both provided with a clamping assembly, and a rotating assembly is provided on the rotating bracket; the clamping assembly comprises a first clamping oil cylinder and a second clamping oil cylinder, the piston rods of the first clamping oil cylinder and the second clamping oil cylinder are both connected with a group of clamping blocks, and the working surfaces of the clamping blocks are provided with frosted patterns.

[0007] Working process or working principle:

[0008] When in use, the drill rod is placed in the first drill rod rack and the second drill rod rack, and the thread connection of the drill rod is adjusted to be located in the gap between the first drill rod rack and the second drill rod rack. Then, the first clamping oil cylinder and the second clamping oil cylinder drive the clamping block to clamp the drill rod, and the rotating assembly drives the rotating frame to move along the arc guide rail on the second fixed frame, thereby realizing the rotation of the second drill rod rack, and then realizing the rotation of the two sections of drill rod, and realizing the disassembly of the drill rod.

[0009] The rotating assembly comprises a rotating oil cylinder hinged on the slide, the piston rod of the rotating oil cylinder is hinged to the rotating bracket, and the rotating bracket is driven to rotate by the rotating oil cylinder, thereby realizing the rotation between the two sections of the drill pipe.

[0010] There are two rotating oil cylinders, which are symmetrically arranged at both ends of the slide. The piston rods of the two rotating oil cylinders are hinged to the rotating bracket. The symmetrical arrangement of the two rotating oil cylinders can make the rotating torque more even.

[0011] The first drill rod rack and the second drill rod rack are both hinged with a stopper rod at their openings. The stopper rod can be arranged to prevent the drill rod and the drill rod rack from falling off during operation.

[0012] The set of clamping blocks is provided with two, and the two clamping blocks are arranged in a V shape.

[0013] The distance between the two clamping blocks connected by the first clamping cylinder is greater than the distance between the two clamping blocks connected by the second clamping cylinder. By setting the position distances of the two groups of clamping blocks to different sizes, the clamping blocks can be adapted to drill rods of various specifications.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model can vertically load and unload the drill rod when the equipment is in operation, and the drill rod can be directly placed in the clamping assembly without being inserted at one side, which is convenient for processing and can save manpower for some small drill rods.
