the utility model discloses a drill rod joint model vernier dipperstick is whole to be made by the steel, and is firm resistant to make.
As shown in fig. 1 and 2, the vernier measuring scale for measuring the type of the drill pipe joint comprises a main scale 1, a vernier sliding sleeve 2, a locking device 3, a female buckle inner diameter measuring claw and a male buckle outer diameter measuring claw.
The main ruler 1 is a main body part of a tool for measuring the size of a drill tool joint and is a straight ruler plate, the thickness of the main body part is about 3mm, the length of the main body part is 21cm, and a hollow circle 11 for hanging is arranged at the tail of the ruler, so that a technician can conveniently store the main body part. The front side of the main ruler 1 is marked with model marks 12 (including various types and kinds of drill tool joints) for determining the corresponding models of the joints (as shown in figure 1), the back side is marked with digital marks 13 (male and female joint diameter data corresponding to each model) for determining the sizes of the joints (as shown in figure 2), and the front side and the back side of the main ruler 1 are provided with corresponding character marks for remark explanation; the three kinds of marks have the characteristics of intuition, no need of mutual conversion, simplicity and understandability.
The vernier sliding sleeve 2 is divided into an upper part and a lower part, is clamped and sleeved at the outer edge of the main ruler 1, is internally provided with a movable slide rail, the lower end of the movable slide rail is provided with a semicircular force application button 21, the main ruler 1 is held by a hand, the lower force application button 21 is buckled by a thumb, two unconnected objects move relatively by utilizing the principle of the action of friction force, and the movement distance control of the vernier sliding sleeve 2 relative to the main ruler 1 is completed by controlling the magnitude of the applied force.
The locking device 3 is a knob screw (a top thread) embedded and installed at the edge of the vernier sliding sleeve 2, and after the size ratio of the joint is completed, the knob screw is screwed to slowly go deep until the knob screw collides with the main scale 1, so that the main scale is acted by force, the main scale 1 is pressed until the knob screw cannot be screwed continuously, and the aim of locking the vernier sliding sleeve 2 can be achieved.
As shown in fig. 1, the female buckle inner diameter measuring claw is divided into a left half and a right half, the right half 41 of the female buckle inner diameter measuring claw is connected with the main ruler 1, the left half 42 of the female buckle inner diameter measuring claw is connected with the vernier sliding sleeve 2, the overall shape is similar to an olecranon shape, during measurement, the left half 42 of the female buckle inner diameter measuring claw is driven to move rightwards through the vernier sliding sleeve 2, the left half and the right half of the female buckle inner diameter measuring claw do cross movement in opposite directions, the side in the moving direction (the opposite side of the left half and the right half of the female buckle inner diameter measuring claw) is designed into a vertical edge (a vertical plane) perpendicular to the main ruler 1, and the vertical edges of the left half and the right half of the female buckle inner diameter measuring claw are respectively.
As shown in fig. 1, the pin outer diameter measuring claw is divided into a left pin and a right pin, the left pin 51 is connected to the main ruler 1, the right pin 52 is connected to the cursor sliding sleeve 2, and the overall shape is similar to an olecranon shape, during measurement, the right pin 52 is driven by the cursor sliding sleeve 2 to move rightwards, the left pin and the right pin are opposite in direction and move crosswise, the side of the moving direction (the opposite side of the left pin and the right pin) is designed to be a vertical edge (vertical plane) perpendicular to the main ruler 1, and the vertical edges of the left pin and the right pin are respectively attached to the root of the joint of the drilling tool, so as to measure the maximum outer diameter of the drilling tool.
The vernier sliding sleeve 2 drives the left pedal 42 of the female buckle inner diameter measuring claw and the right pedal 52 of the male buckle outer diameter measuring claw to move and adjust back and forth until the tool joint can be clamped; after the clamping measurement is finished, the locking device 3 is screwed down before the sliding sleeve is taken down, so that the vernier sliding sleeve 2 is prevented from sliding again by manual force application; and reading the front and back marks corresponding to the zero point on the main scale 1 to obtain the model and size data of the tool.
When the outer diameter of the pipe body to be measured is large, especially when the pipe body is measured in the middle section, due to the size limitation of the left and right halves of the pin outer diameter measuring claw (that is, the length of the left and right halves is too short), the left and right halves are difficult to be attached to the pipe body at the same time, at this time, an extension rule 6 as shown in fig. 3 needs to be additionally installed on the left and right halves of the pin outer diameter measuring claw respectively, specifically, two threaded holes are reserved on the extension rule 6, two threaded holes are correspondingly reserved on the left and right halves of the pin outer diameter measuring claw respectively, the two extension rules 6 can be fixedly connected to the left and right halves of the pin outer diameter measuring claw correspondingly by being locked in the threaded holes through fastening screws, and the full-size measurement requirement of the measuring scale can be met after the extension rule 6 is completely installed.
In summary, the present invention is not limited to the above embodiments, and those skilled in the art can provide other embodiments within the technical teaching of the present invention, but these embodiments are included in the scope of the present invention.
