Description

Technical Field

[0001] This utility model belongs to the field of measurement technology for arc-shaped steel structures, and in particular relates to a high-precision measurement device for arc-shaped steel structures. Background Technology

[0002] Curved steel structures are a special type of steel structure design. "Curved" refers to the structure's curved or circular shape, while "steel structure" refers to the use of steel as the primary material. This structural form typically involves complex geometry and precise engineering calculations to ensure stability, safety, and aesthetics.

[0003] To extend the service life of steel structures, a coating is usually applied to their surface. However, due to the curved shape of the surface, it is difficult to measure the coating thickness after application. It is also difficult for workers to keep the equipment perpendicular to the steel structure, resulting in low measurement accuracy. Therefore, a high-precision measuring device for curved steel structures is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision measuring device for arc-shaped steel structures. By using rollers and balls, the correct angle between the substrate and the steel structure is maintained, improving the measurement accuracy and facilitating operation. At the same time, the steel structure is attracted by a magnet, thereby maintaining the stability of the substrate and the coating thickness gauge, making it convenient for users to record data and operate the device. This invention solves the existing technical problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A high-precision measuring device for an arc-shaped steel structure includes: a base plate disposed on one side of the steel structure; two upright plates fixedly connected to one side of the base plate, the two upright plates being symmetrically arranged; rollers that contact the steel structure are installed on one side of each upright plate; and ball bearings that cooperate with the steel structure are rotatably connected to the top of each upright plate. During use, the device can maintain the correct angle between the base plate and the steel structure through the cooperation of the rollers and ball bearings, thereby improving the measurement accuracy and facilitating operation.

[0007] A mounting bracket is movably mounted on the surface of the substrate. A first slide rail is formed on the surface of the mounting bracket, and a sliding frame is slidably connected within the first slide rail. A through-type fixing bolt is rotatably connected to the surface of the sliding frame. A clamping plate is provided at the bottom of the sliding frame. The clamping plate is slidably connected to the first slide rail and threadedly connected to the fixing bolt. A coating thickness gauge is fixedly connected to the bottom of the clamping plate. A side plate perpendicular to the mounting bracket is fixedly connected to the bottom of the mounting bracket. A second slide rail is formed on one side of the side plate. The side plate works in conjunction with the mounting bracket to adjust the position of the coating thickness gauge, improving the flexibility of use.

[0008] As a further embodiment of this utility model, a sleeve is fixed to the surface of the substrate by bolts, and the fixing bracket is inserted into the sleeve.

[0009] As a further embodiment of this utility model, a through-hole set screw is threaded onto one side of the sleeve, and the set screw abuts against the fixing frame.

[0010] As a further improvement of this utility model, two rollers are provided on one side of the upright plate.

[0011] As a further improvement of this utility model, a set of scale lines are provided on both the surface of the fixing frame and one side of the side plate.

[0012] As a further embodiment of this utility model, an n-shaped slide rod is slidably connected to one side of the substrate, and magnets are fixedly connected to both ends of the slide rod. Elastic elements are provided between the magnets and the substrate.

[0013] As a further embodiment of this utility model, the elastic element is a tension spring, which is fixed between the magnet and the substrate. The steel structure is attracted by the magnet, thereby maintaining the stability of the substrate and the coating thickness gauge, making it convenient for people to record data and operate.

[0014] As a further improvement of this invention, a handle is fixedly connected to one side of the substrate.

[0015] As a further improvement of this utility model, the handle is provided with a rubber sleeve around its circumference.

[0016] As a further improvement of this utility model, the bottom of each upright plate is fixedly connected with a support foot.

[0017] In this application, during use, the substrate is placed on one side of the curved steel structure, and four rollers contact the steel structure to maintain the substrate's angle. Simultaneously, ball bearings contact the other side of the steel structure to keep the substrate horizontal, thus maintaining the coating thickness gauge perpendicular to the steel structure, improving measurement accuracy. The coating thickness gauge then measures the coating on the steel structure. During measurement, a magnet can be brought close to the steel structure to attract it, maintaining the stability of the substrate and the coating thickness gauge, facilitating data recording and operation. To change positions, pull the slider to disengage the magnet from the steel structure, then slide the substrate. Operation is convenient. When measuring the other side of the steel structure, loosen the fixing bolt, remove the coating thickness gauge, and reinstall it on the side plate to measure the side of the steel structure. Loosening the fixing bolt also allows for adjustment of the coating thickness gauge's position, increasing flexibility and measurement positions for user convenience.

[0018] The embodiments of this utility model have the following beneficial effects:

[0019] In this utility model, by installing rollers and balls on the clamping plate, the device can maintain the correct angle between the base plate and the steel structure through the cooperation of the rollers and balls during use, thereby improving the measurement accuracy and facilitating operation.

[0020] In this invention, by installing a movable magnet on one side of the substrate, the steel structure is attracted by the magnet, thereby maintaining the stability of the substrate and the coating thickness gauge, making it convenient for people to record data and operate.

[0021] In this invention, the correct angle between the substrate and the steel structure is maintained by the cooperation of rollers and balls, which improves the accuracy of measurement and facilitates operation. At the same time, the steel structure is attracted by a magnet, which maintains the stability of the substrate and the coating thickness gauge, making it convenient for people to record data and operate.

[0022] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
