[0031] In the related art, there is a technical problem of low detection efficiency in laser tracking detection. The embodiments of the present application provide a measuring tool, which can at least solve the technical problem of low detection efficiency in laser tracking detection to some extent.

[0032] The present application will be described below in conjunction with the accompanying drawings and specific embodiments:

[0033] As shown in Figure 1 and Figure 2 , the measuring tool 100 includes an extension rod 110, an adjusting rod 120, a mounting seat 130, and a target ball 140. One end of the adjusting rod 120 is connected to one end of the extension rod 110, the adjusting rod 120 can be bent and can be kept in a bent state. The mounting seat 130 is connected to the other end of the adjusting rod 120. The target ball 140 is mounted on the mounting seat 130.

[0034] The adjusting rod 120 has the ability to bend and deform, and can maintain a stable shape after bending. In order to achieve this function, the adjusting rod 120 can be made of materials with high elastic modulus and good toughness, such as spring steel, etc., which can provide sufficient shape stability after bending. In addition, the adjusting rod 120 can be designed as a multi-section structure composed of multiple connected sections, each section is connected by hinges or flexible connectors, so that each section can bend independently within a certain range, thereby realizing flexible deformation of the whole. Through the design of the locking mechanism, the adjusting rod 120 can fix the shape after bending to ensure the stability during the measurement process. In another design, the adjusting rod 120 can adopt a bellows type structure. The bellows has good flexibility and bending ability, and can easily realize bending deformation under external force, and maintain a certain bending shape after the external force is removed. In some embodiments, the adjusting rod 120 is a bellows, which can be directly purchased from the market, and has simple structure and high flexibility. In some embodiments, the adjusting rod 120 is a wire.

[0035] The measuring tool 100 provided by the application improves the efficiency and convenience of laser tracking detection through the combined design of the extension rod 110, the adjusting rod 120, the mounting seat 130 and the target ball 140. Specifically, the measuring personnel do not need to set up a scaffold or climbing equipment, but only need to hold the extension rod 110 and adjust the bending angle of the adjusting rod 120 according to the measurement requirements, so as to position the target ball 140 to the target position. The design that the adjusting rod 120 can be bent enables the target ball 140 to be flexibly adjusted in the three-dimensional space, so as to adapt to the measurement requirements of different heights and angles, greatly expanding the measurement range. In addition, the measuring tool 100 is simple in structure and convenient to operate, reduces the cumbersome preparation work and the risk of high-altitude operation in the traditional detection, not only improves the detection efficiency, but also reduces the safety risk and equipment rental cost. Therefore, the measuring tool 100 can solve the problem of low efficiency of traditional laser tracking detection, and is suitable for precision detection in complex scenes such as large metallurgical equipment.

[0036] In some embodiments, the adjusting rod 120 and the extension rod 110 are detachably connected. The detachable connection between the adjusting rod 120 and the extension rod 110 can be in various ways, such as threaded connection, bolt connection, clamping, etc. The detachable connection between the adjusting rod 120 and the extension rod 110 enables the measuring tool 100 to be disassembled into multiple small parts, facilitating the storage or transportation of the measuring tool 100 in limited space. In addition, the detachable connection also makes the maintenance and cleaning of the tool more convenient, and the user can handle a certain part according to the needs, without the need to operate the measuring tool 100 as a whole.

[0037] In some embodiments, the extension rod 110 includes a rod body 111 and a connecting piece 112 fixedly connected to the rod body 111 near one end of the adjusting rod 120, and the end of the adjusting rod 120 near the connecting piece 112 is threadedly connected to the connecting piece 112. The connecting piece 112 is fixedly connected to the extension rod 110, and the adjusting rod 120 is threadedly connected to the connecting piece 112. The threaded connection between the connecting piece 112 and the adjusting rod 120 facilitates the disassembly or installation of the adjusting rod 120 from or on the connecting piece 112.

[0038] In some embodiments, the connecting piece 112 is provided with an internal thread, and the end of the adjusting rod 120 near the connecting piece 112 is provided with an external thread. The external thread of the adjusting rod 120 threadedly cooperates with the internal thread of the connecting piece 112, so as to threadedly connect the end of the adjusting rod 120 near the connecting piece 112 to the connecting piece 112.

[0039] In some embodiments, the connecting piece 112 is bonded to the rod body 111.

[0040] In some embodiments, the rod body 111 is a telescopic rod that can be extended or shortened. The structure of the telescopic rod is widely used in products such as mop rods, fishing rods, and shower curtain rods, and is diverse and known to those skilled in the art. The telescopic rod generally includes multiple segments that are connected in sequence and are provided with a locking mechanism between adjacent segments so that the adjacent segments can be locked after being slid to a certain position. By setting the rod body 111 as a telescopic rod, the length of the rod body 111 can be changed, so that the measuring tool 100 can meet the requirements of close-range measurement and long-distance measurement, thereby adapting to various measurement scenarios. The measuring personnel can quickly adjust the measuring tool 100 without replacing the rod body 111 of different lengths, thereby improving the detection efficiency. In addition, the telescopic function of the telescopic rod allows the measuring tool 100 to be shortened in a non-use state, thereby reducing the occupied space and facilitating carrying, storage, and transportation, which is suitable for use in environments with limited space or frequent movement.

[0041] In some embodiments, the mounting seat 130 is detachably connected to the adjusting rod 120. The mounting seat 130 and the adjusting rod 120 can be detachably connected in various ways, such as threaded connection, bolt connection, clamping, etc. The detachable connection of the adjusting rod 120 and the mounting seat 130 allows the measuring tool 100 to be disassembled into multiple small parts, thereby facilitating the storage or transportation of the measuring tool 100 in a limited space. In addition, the detachable connection also makes the maintenance and cleaning of the tool more convenient, and the user can handle a certain part as needed without having to operate the entire measuring tool 100.

[0042] In some embodiments, the mounting seat 130 is provided with a mounting groove 130a, the inner wall of the mounting groove 130a is provided with an internal thread, and the end of the adjusting rod 120 close to the mounting seat 130 is provided with an external thread. The external thread and the internal thread are threadedly connected. The threaded connection of the mounting seat 130 and the adjusting rod 120 allows the mounting seat 130 to be installed on or removed from the adjusting rod 120 by screwing, thereby facilitating the disassembly and installation of the mounting seat 130.

[0043] In some embodiments, the measuring tool 100 further includes a magnet 150 that is clamped between the mounting seat 130 and the adjusting rod 120. Under the action of the magnet 150, the target ball 140 is adsorbed on the mounting seat 130. It should be noted that the target ball 140 should be made of metal materials such as iron, nickel, and cobalt to ensure that the target ball 140 can be adsorbed on the mounting seat 130 by the magnet 150. After such design, the target ball 140 is fixed by magnetic force without complex installation steps, and the measuring personnel can quickly install or disassemble the target ball 140 to the target position, which helps to improve the measurement efficiency.

[0044] In some embodiments, the magnet 150 is arranged at the bottom of the installation groove 130a, and gradually abuts against the installation seat 130 and the adjusting rod 120 during the process of screwing the installation seat 130, so as to be clamped between the installation seat 130 and the adjusting rod 120.

[0045] In some embodiments, the installation seat 130 is provided with a positioning groove 130b, which is arranged opposite to the magnet 150, and at least part of the target ball 140 is located in the positioning groove 130b and abuts against the groove wall of the positioning groove 130b. The target ball 140 is partially embedded in the positioning groove 130b and abuts against the groove wall of the positioning groove 130b, and through the arrangement of the positioning groove 130b, the shaking or deviation of the target ball 140 during the measurement process can be effectively prevented, so as to ensure the stability and reliability of the measurement data.

[0046] In some embodiments, the cross-sectional area of the positioning groove 130 gradually decreases from the opening to the bottom of the positioning groove 130. That is, the positioning groove 130b is tapered, and the end far away from the installation seat 130 is larger than the end close to the installation seat 130. This design can enable the positioning groove 130b to position target balls 140 of different sizes.

[0047] The working principle of the measurement tool is introduced as follows:

[0048] As shown in Figure 3 When measuring the metallurgical equipment, the measurement personnel stretches the rod body 111 to an appropriate length and locks it according to the target position where the target ball 140 is to be placed, and bends the adjusting rod 120 to an appropriate curvature, and then magnetically attracts the target ball 140 to the installation seat 130, and adjusts the position of the target ball 140, so that the target ball 140 is aligned with the light source of the laser tracker. Finally, the target ball 140 is placed on the large equipment to be measured, and the brain background of the laser tracker can read out the shape profile and three-dimensional coordinates of the large equipment.
