[0055] In this embodiment, at least one angle ruler assembly 8 is also included. At least one of the fixed component and the movable component 2 is provided with an angle ruler assembly 8 for positioning. The angle ruler assembly 8 includes a first ruler 81 and a second ruler 82. The fixed component and / or the movable component 2 is connected to the corresponding first ruler 81.

The support frame 23 includes legs 231, positioning rollers 232 and connecting rods 233. The number of legs 231 is two and they are arranged opposite to each other. Each leg 231 is connected to the moving seat 21 and a positioning roller 232 is arranged at the end of each leg 231 away from the moving seat 21. The two oppositely arranged positioning rollers 232 are rotatably connected to the two ends of the connecting rod 233 respectively. The two legs 231, the two positioning rollers 232 and the connecting rod 233 are connected to each other in a gate shape. The distance measuring component 3 is arranged on the connecting rod 233, that is, the laser rangefinder 31 is connected to the connecting rod 233. In this embodiment, the connecting rod 233 is cross-shaped to enhance the stability of the connection with the distance measuring component 3. This embodiment adopts a double-leg design, which can not only ensure the stability of the support for the distance measuring component 3, but also realize the rotation connection between the distance measuring component 3 and the moving component 2, ensuring the flexibility of the rotation adjustment and the stability of the adjustment process. The legs 231 can be made of grooved or square steel and connected to the moving seat 21 through angle steel, etc. The rotation installation method of the positioning roller 232 and the connecting rod 233 is a prior art, which is not discussed in the present invention.

[0057] In this embodiment, the target plate 41 is rotatably connected to the fixed component, and the target plate 41 is provided with a mark and / or a verticality detection component. In this embodiment, the target plate 41 is provided with both a mark to cooperate with the distance measuring component 3 for measurement and a verticality detection component to detect the verticality of the target plate 41.

[0058] In this embodiment, the mark includes a bull's eye line 412 provided on the target plate 41. When measuring, the laser can be projected onto the bull's eye line 412 for accurate measurement; the mark also includes a target ruler 413 provided on the target plate 41.

The operation is convenient, the measurement is accurate, the measurement efficiency is improved, and the measurement quality is guaranteed. In this embodiment, the fixed seat 42 is provided with a centering line 422. The positioning line 422 is the projection line of the bull's eye line 412 on the fixed seat 42 when the target plate 41 is perpendicular to the fixed seat 42. This design can indirectly extend the bull's eye line 412, making it more convenient for the laser to correspond to the bull's eye line 412. The laser can correspond to the centering line 422 first, and then adjust to correspond to the bull's eye line 412. The adjustment is flexible and easy to use. The target plate 41 is also provided with a verticality detection component 411. The target plate 41 is rotatably connected to the fixed seat 42 and the verticality is detected by the verticality detection component 411.

[0059] In this embodiment, the target measuring mechanism 4 includes a target plate adjusting roller 414, through which the target plate 4 is rotatably connected to the fixing seat 42; the target plate mechanism 4 also includes a positioning plate 43 and a positioning plate adjusting roller 431, through which the positioning plate 43 is also rotatably connected to the fixing seat 42, and the positioning plate 43 is provided with a target plate embedding hole to be embedded with the target plate 41, that is, when the target plate 41 and the positioning plate 43 are adjusted to the same angle as the fixing seat 42, the target plate 41 can be nested in the positioning plate 43. During measurement, the target plate 41 is usually adjusted to be perpendicular to the fixing seat 42, and the verticality is ensured by the verticality detection component 411 to ensure the measurement accuracy; the target plate 41 is also provided with a limiter 415, and when the target plate 41 and the positioning plate 43 are adjusted to the same plane, the target plate 41 and the positioning plate 43 are connected into a whole by the limiter 415 to ensure stable fixation. The target plate 41 and the positioning plate 43 are rotatably connected to the fixing seat 42 respectively. When transporting or storing, the target plate 41 and the positioning plate 43 can be adjusted to be parallel to the fixing seat 42 to reduce the floor space, and folded for easy storage or transportation; when moving, the positioning plate 43 can also be rotated to use it as a handle for transportation.

[0060] On the other hand, the present invention also provides a method for using the component measuring device, comprising the following steps:

[0061] The target plate 41 is set at the measurement starting point and fixed by a fixing component. The distance measuring component 3 can measure the distance from the target plate 41. The distance measuring component 3 is driven to move by the moving component 2 to adjust the distance. When the distance adjustment is completed, the position of the distance measuring component 3 is recorded for positioning.

[0062] A specific working process of this embodiment is as follows:

[0063] The component measuring device can be transported in parts to the location to be measured and then assembled. During transportation, the positioning plate 42 or the target plate 41 can be rotated to reduce the occupied space, and the positioning plate 42 can also be used as a handle.

[0064] Place the I-beam component 1 on the assembly platform, adjust the position of the fixing seat 42 on the web of the component 1: rotate the second ruler 82 to make it perpendicular to the first ruler 81, quickly position the target plate 41 and the flange of the component 1 through the first ruler 81 and the second ruler 82, and measure the distance between the target measuring mechanism 4 and the edge of the component 1, so that the target plate 41 is set at the position of the measurement starting point and fixed by adsorption through the magnetic component 421. The line end of the centering line 422 can also be used as the measurement starting point and reference point, and the material is numbered on the web.

[0065] The target plate 41 is rotated, usually adjusted to be perpendicular to the fixing seat 42 and the verticality is detected by the verticality detection component 411 ; in other usage scenarios, the placement angle of the target plate 41 can also be adjusted according to needs.

[0066] The measuring mechanism is placed on the web, the setting angle of the laser rangefinder 31 is adjusted by the support frame 23, and the angle positioning component is used to detect whether the setting angle is accurate. The corresponding angle ruler component can then be used to position the measuring mechanism. The method of positioning the measuring mechanism by the angle ruler component is the same as the method of positioning the target measuring mechanism 4, so that the distance measuring component 3 is parallel to the target plate 41.

[0067] The controller 24 is used to adjust the movement of the roller 22 so that the measuring mechanism moves along the length direction of the component 1, and the laser rangefinder 31 is turned on and adjusted to emit laser light to project onto the bull's eye line 412. During the movement, the display panel 311 can display the distance from the measurement starting point. When the positioning required by the design is reached, the alarm component 7 can give an alarm prompt, and the material numbering pen 62 is used to mark the material.

[0068] In different working scenarios, the target measuring mechanism 4 can be used alone, and it can be positioned and fixed at the measurement starting point, and the construction personnel can then use a steel tape measure or the like to cooperate in positioning; in a construction scenario where an obvious measurement starting point has been set, such as using the node plate 9 connected to the component 1 as the measurement starting point, the measuring mechanism can be used alone for positioning and numbering.

[0069] This embodiment can be disassembled or used in combination, and can be flexibly applied to various measurement scenarios, which can reduce the number of operators, reduce measurement deviation, improve operation efficiency, and reduce operation cost. It can improve the traditional two-person length measurement and material numbering to a single-person operation, and can also locate the node plate 9 during the measurement and material numbering of the component 1, and re-measure the length of the component 1 after it is made to ensure that the length deviation meets the specification requirements. The device occupies a small space, has a smoother operation process, improves work efficiency, shortens the construction period, has a low manufacturing cost, and is easy to disassemble and assemble. It can be used for multiple projects, which is convenient and fast.

In this embodiment, the connecting assembly 54 includes a connecting plate that is connected to the lug 51 and has a connecting hole, and the connecting hole is detachably connected to the moving seat 21 through a bolt; in other embodiments, the detachable connection method can also be flexibly selected based on the general technical knowledge of those skilled in the art.

[0072] This embodiment can be applied to measure the side elevation of the component 1, such as measuring and marking the outer side of the flange plate. The fixing seat 42 fixes the target plate 41 to the outside of the side of the component 1 through magnetic force, and the measuring mechanism is movably hung on the outside of the side of the component 1 through the hanging component 5.
