TECHNICAL FIELD

[0001] The utility model relates to drilling equipment technical field especially relates to an adjustable drilling impactor. BACKGROUND

[0002] The work of drilling a hole in the ground from the surface by mechanical equipment or manpower is called drilling. It usually refers to the engineering of drilling a wellhole and a large-diameter water supply well for exploring or developing liquid and gaseous mineral products such as oil and natural gas. Drilling is widely used in national economic construction. Impactors are often used during drilling. The impactor is usually a circular tube, and the impact head is a component that directly acts on the rock as the impactor. It frequently faces the problem of wear and tear, so it needs to be replaced and maintained regularly.

[0003] For the above and existing related technologies, the inventors believe that the following defects often exist: the impact head on the traditional impactor is usually installed by bolt fastening or welding. Bolt fastening is time-consuming and laborious, and multiple bolts are operated complicatedly, which greatly increases the labor intensity and operation time. Although the welding method is stable, it is difficult to remove the impact head after it is damaged. Improper operation can also damage the impactor body, affecting the service life. At the same time, the impactor is inconvenient to disassemble and assemble, and it is difficult to replace it in time, which leads to long-term downtime of the equipment and seriously affects the continuity and efficiency of drilling operations. Therefore, a kind of adjustable drilling impactor is proposed to solve the above problems. CONTENT OF THE UTILITY MODEL

[0006] The above components achieve the following effects: the impact head is convenient for workers to disassemble and assemble, the combination of the spring and the fixed rod allows the fixed rod to stretch and contract in the circular groove under the action of the spring, and when installing the impact head, the fixed rod automatically slides into the clamping hole to complete the fixation under the action of the spring. When disassembling, the fixed rod is pressed to retract into the circular groove, so that the impact head can be easily taken out of the circular mounting bracket, improving the practicality of the device.

[0007] Preferably, the inner wall of the circular mounting frame is fixedly connected with two guide blocks, and the upper half of the guide block is an arc surface.

[0008] The effect achieved by the above components is that the two guide blocks can limit the impact head, making it more stable to slide in the circular mounting frame, facilitating accurate alignment and clamping of the fixing rod and the clamping hole, and facilitating installation and positioning of the impact head.

[0009] Preferably, the circular arc surface of the impactor body is fixedly connected with a fixed block, the fixed block is rotatably connected with a threaded rod, the circular arc surface of the threaded rod is threadedly connected with a circular ring block, the circular arc surface of the impactor body is fixedly connected with an arc-shaped block, the lower surface of the arc-shaped block is fixedly connected with a long rod, and the circular arc surface of the circular ring block is slidably connected with the long rod.

[0010] The effect achieved by the above components is that the position of the circular ring block can be adjusted by rotating the threaded rod, and when the circular ring block blocks the impact head, the fixed rod can be blocked and constrained, avoiding impact on the fixed rod during use of the impact head, thereby preventing the impact head from falling off and ensuring the stability and safety of the drilling operation.

[0011] Preferably, the end of the threaded rod away from the circular mounting frame is fixedly connected with a circular shaft, and the circular arc surface of the circular shaft is provided with a plurality of anti-skid grooves.

[0012] The effect achieved by the above components is that the circular shaft at one end of the threaded rod is provided with anti-skid grooves, facilitating the staff to grasp and rotate the circular shaft with hands or tools, effectively increasing the friction, making the operation of adjusting the position of the circular ring block by rotating the threaded rod more effortless, and thus the position of the circular ring block can be adjusted in time to quickly constrain the fixed rod.

[0013] Preferably, the circular arc surface of the circular mounting frame is fixedly connected with two stop blocks, and the size of the circular ring block is smaller than the size between the sides of the two stop blocks away from each other.

[0014] The effect achieved by the above components is that the two stop blocks on the circular mounting frame can limit the movement range of the circular ring block, preventing it from moving excessively on the threaded rod and leaving the working position, and ensuring that the circular ring block can always constrain the fixed rod in the appropriate area.

[0015] Preferably, the front end of the fixed rod is spherical, and the size of the fixed rod is adapted to the size of the clamping hole.

[0016] The effect achieved by the above components is that the front end of the fixed rod is spherical, which makes it easier to slide into the clamping hole when installing the impact head, reduces the resistance during insertion, and reduces the operation difficulty.

[0017] In summary, the beneficial effects of the present application are:
