Description

A forged drill rod strength testing device Technical Field

[0001] This utility model belongs to the field of drill rod processing technology, specifically relating to a forged drill rod strength testing device. Background Technology

[0002] Drill rods are tools used in tunneling engineering to connect drill bits and rock drills. During the manufacturing process, drill rods usually undergo a forging process to improve their hardness, wear resistance, and overall mechanical properties, ensuring their reliability and service life during use. After forging, the drill rods need to be subjected to strength testing to check whether they meet production standards.

[0003] According to the patent announcement number CN221100319U, a steel strength testing device for production workshops, while possessing advantages such as convenient clamping and conveying of steel and circumferential rotation testing, facilitating multi-position testing of conveyed steel, reducing labor intensity of manual conveying, improving the convenience of steel conveying, and enabling testing of different steel surfaces, thus increasing the testing range and improving the accuracy of steel strength testing equipment, this patented technology has the following drawbacks in actual use: it is less effective for steel of different thicknesses. During testing, the height of the steel cannot be adjusted. When the clamping block clamps a thinner piece of steel, the steel needs to be rotated, so it is fixed in the center area of ​​the hollow wheel. At this time, the bottom of the steel cannot contact the top of the base, which will cause the steel to tilt during testing, resulting in damage to the steel or the clamping block. In addition, when fixing a longer or heavier piece of steel, only one end of the steel is clamped, which will lead to an unstable clamping. Furthermore, when testing steel with a circular cross-section, the steel may slip. To address these issues, we have proposed a forged drill rod strength testing device. Summary of the Invention

[0004] The purpose of this invention is to provide a forged drill rod strength testing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a forged drill rod strength testing device, comprising a base, a sliding box slidably connected to the inner side of the base, a lifting motor fixedly connected to the inner cavity of the sliding box, lifting gears fixedly connected to the two output shafts of the lifting motor, a lifting plate meshing with one side of the two lifting gears, the lifting plate slidably connected inside the sliding box, a toothed turntable rotatably connected to the top of one side of the lifting plate, two clamping screws rotatably connected inside the toothed turntable, one end of the clamping screws penetrating the toothed turntable, two arc-shaped plates threaded to the outside of the clamping screws, the arc-shaped plates slidably connected to one side of the toothed turntable, a rotary motor fixedly connected to the other side of the lifting plate, the output shaft of the rotary motor penetrating the lifting plate, a rotary gear fixedly connected to the output shaft of the rotary motor, the rotary gear meshing with the bottom of the toothed turntable, and a testing platform fixedly connected to the inner side of the base.

[0009] In a preferred embodiment, a vertical plate is fixedly connected to the top of the movable block, and a cylinder is fixedly connected to the inner side of the vertical plate. A dual-output shaft motor is fixedly connected to the top of the cylinder and the top of one side of the vertical plate.

[0010] In a preferred embodiment, the two pressing screws have opposite thread directions, and the cylinder penetrates the vertical plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This forged drill rod strength testing equipment is equipped with a lifting motor and a lifting plate. By driving the lifting motor, the output shaft of the lifting motor rotates, which in turn drives the lifting gear to rotate, thereby causing the lifting plate and the toothed turntable to move up and down. This allows the height of the drill rod to be adjusted when fixing drill rods of different thicknesses, so that the bottom of the drill rod contacts the testing table, thus preventing damage to the drill rod or the arc block during testing.

[0013] 2. This forged drill rod strength testing equipment, by setting up a dual-output shaft motor, slider, slide rod, rotating rod, rotating wheel, and ball bearings, allows the drill rod to be fixed at one end. By driving the dual-output shaft motor, the two output shafts of the motor rotate, causing the slider to move. Under the action of the slide rod, the rotating rod drives the rotating wheel to rotate, causing the rotating wheel to contact the surface of the drill rod. Under the action of the two rotating wheels and the ball bearings, the other end of the drill rod is limited and supported. However, it can allow the drill rod to rotate under external force, preventing the drill rod from sliding or tilting. Attached Figure Description

[0024] Please refer to Figures 1-5. To fix the drill rod and inspect multiple areas of it, a sliding box 2 is slidably connected to the inner side of the base 1.

A ball bearing 27 is rotatably connected to the bottom of the cylinder 20.By rotating the output shaft of the lifting motor 3, the lifting gear 4 is driven to rotate, thereby moving the lifting plate 5 up and down to adjust the height of the toothed turntable 6.

[0025] The working principle and usage process of this utility model are as follows: First, the drill rod is placed above the testing platform 11. The hydraulic cylinder 12 is driven to extend its output end, causing the lower pressure plate 13 to descend and apply pressure to the drill rod. The pressure value can be read from the pressure gauge 15 to check whether the forged drill rod meets the production standards, thereby achieving the purpose of strength testing of the forged drill rod. By driving the output shaft of the lifting motor 3 to rotate, the lifting gear 4 is driven to rotate, thereby causing the lifting plate 5 to move up and down to adjust the height of the toothed turntable 6. By turning the handle, the clamping screw 7 is rotated, causing the arc plate 8 to move and clamp one end of the drill rod. The other end of the drill rod is passed through the cylinder 20. The dual-output shaft motor 21 is driven to rotate the two output shafts of the dual-output shaft motor 21, causing the lower pressure screw 22 to rotate, thereby causing the slider 2 to move up and down. 3. Movement: The movement of slider 23 drives the movement of slider 24. Simultaneously, slider 24 moves up and down within slider 23. At this time, rotating rod 25 rotates accordingly, causing rotating wheel 26 to contact the drill rod. Under the contact of ball bearing 27 and two rotating wheels 26, the other end of the drill rod is fixed. At this time, the drill rod is in a horizontal state, and the bottom of the drill rod is in contact with the detection table 11, thus achieving the purpose of fixing the drill rod. When it is necessary to detect other areas of the drill rod, the output shaft of the moving motor 16 is rotated by driving the moving screw 17 to rotate, thereby moving the moving block 18 and thus moving the drill rod. The output shaft of the rotating motor 9 is rotated by driving the rotating gear 10 to rotate, thereby rotating the toothed turntable 6 and thus rotating the drill rod. This achieves the purpose of fixing the drill rod and detecting multiple areas of the drill rod.
