Description

Technical Field

[0001] The utility model belongs to the technical field of coating thickness detection, and particularly relates to a device for detecting the coating thickness of a steel structure. Background Art

[0002] The thickness of the cross-section of a steel structure is often affected by the processing accuracy and cross-section corrosion. In particular, corrosion will reduce the cross-section and decrease the load-bearing capacity, which has a huge impact on the safety of the entire steel structure. Therefore, measuring the thickness of the steel structure cross-section is a very important task.

[0003] Currently, a thickness gauge is usually used to measure the cross-section thickness. The ultrasonic pulse reflection method is adopted. When ultrasonic waves propagate from one homogeneous medium to another homogeneous medium, reflection will occur. When the ultrasonic waves emitted from the probe reach the interface, they are reflected back and received by the receiving probe. By using the time between the emitted pulse and the received pulse, the thickness of the measured part is calculated.

[0004] The whole consists of a main unit, a wire connected to one end of the main unit, and a probe connected to the other end of the wire. Moreover, in order to detect high places such as the roof and beam, the wire has a certain length; however, the wire is randomly suspended in the air under normal conditions. On the one hand, it will be entangled with each other and knotted, and on the other hand, it is easy to pull the wire and cause damage. Content of the Utility Model

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0024] Aiming at the problems in the prior art that the wires are randomly suspended in the air under normal conditions. On the one hand, they will be entangled with each other and knotted. On the other hand, it is easy to pull the wires and cause damage. In this application, a storage space for storing wires is provided on one side of the main unit to prevent the wires from being randomly suspended, and the fixed roller 230 and the movable roller 240 are provided to support the wires and prevent the wires from being entangled and knotted.

[0025] Figure 1 The structural schematic diagram of the steel structure coating thickness detection device is shown; Figure 1 In this case, the steel structure coating thickness detection device includes a main unit 100 and a storage component 200 installed on the main unit 100. The storage component 200 is used to store the wires connected to the main unit 100. It should be noted that in this embodiment, the storage component 200 is provided at the side end of the main unit 100. In other embodiments, the storage component 200 can also be provided on the back of the main unit 100.

[0026] Figure 2 The structural schematic diagram of the storage component 200 is shown; Figure 3 The structural schematic diagram after the wire is wound around the fixed roller 230 and the movable roller 240 is shown; Figure 2 and Figure 3Among them, the storage component 200 includes a cover body 210. The cover body 210 covers one end face of the host 100 and forms the storage space 220. Inside the storage space 220, fixed rollers 230 and movable rollers 240 are arranged at intervals along its longitudinal direction. The fixed rollers 230 and the movable rollers 240 cooperate to form a support surface for winding the wire. The movable roller 240 is slidably arranged in the storage space 220, and the movable roller 240 is driven by an external force to adjust the length of the support surface. By placing the wire in the storage space 220, the wire can be stored. Moreover, the fixed rollers 230 and the movable rollers 240 form a support surface for winding the wire, that is, the wire is wound around the fixed rollers 230 and the movable rollers 240. For example, one end of the wire is connected to the host 100, and after the other end of the wire bypasses the front surfaces of the fixed roller 230 and the movable roller 240, it then bypasses the back surfaces of the movable roller 240 and the fixed roller 230 and winds back, that is, it bypasses one circle of the support surface. Through this structure, the wire can be supported and sorted, so that the wire is neatly wound and arranged between the fixed rollers 230 and the movable rollers 240. And, the movable roller 240 can be driven to slide and adjust the distance between the fixed roller 230 and the movable roller 240. That is to say, when the movable roller 240 is driven, the length of the support surface can be adjusted. For example, driving the movable roller 240 to slide towards the fixed roller 230 means that the length of the support surface is shortened, the wire is slack, allowing the user to stretch and extend it to detect high places. Equally spaced spacer pieces 250 are arranged on the fixed rollers 230 and the movable rollers 240. A spacing cavity for restricting the wire is formed between two adjacent groups of the spacer pieces 250. When the wire is wound into the spacing cavity, adjacent spacing cavities are separated by the spacer pieces 250 to prevent the wires of adjacent groups from interfering with each other, thereby avoiding the wires from being wound around each other. The spacer pieces 250 are inclined. Since the spacer pieces 250 are inclined, in this way, the extension angle of the wire can be restricted to prevent the wire from winding around, that is, the wire from winding around another wire. And, the inclination direction of the spacer pieces 250 matches the extension direction of the wire. The spacing cavities on the fixed rollers 230 and the movable rollers 240 are arranged in a staggered manner. Since the spacing cavities on the fixed rollers 230 and the movable rollers 240 are arranged in a staggered manner, in this way, the wire can avoid interfering with the spacer pieces 250 during the winding process. An inlet 260 is opened at the bottom of the cover body 210, and an outlet 270 is opened at the top of the cover body 210. Both the inlet 260 and the outlet 270 communicate with the storage space 220, and the inlet 260 and the outlet 270 are diagonally arranged relative to the storage space 220. The diagonal here means that the lower left corner corresponds to the upper right corner, or the upper left corner corresponds to the lower right corner. In this way, it conforms to the diagonal arrangement structure to avoid the wire from being folded.

[0027] Continue to refer to Figure 2, on the side of the cover body 210 facing away from the main body 100, a driving assembly 300 for driving the movable roller 240 is provided. The driving assembly 300 includes a slideway 310 formed on the side of the cover body 210 away from the main body 100. A slide bar 320 is slidably connected in the slideway 310. The slide bar 320 is connected to the movable roller 240, and the other end of the slide bar 320 is connected to a pressing member 330. By applying an external force with the thumb against the pressing member 330, the slide bar 320 and the movable roller 240 can be driven to slide along the trajectory of the slideway 310, thereby adjusting the distance between the fixed roller 230 and the movable roller 240.

[0028] In this embodiment, a spring 340 is connected in the slideway 310, and the other end of the spring 340 is connected to the slide bar 320. In the normal state, the slide bar 320 is in a compressed state and the movable roller 240 and the fixed roller 230 have the maximum distance. Through the extrusion of the spring 340, the slide bar 320 and the movable roller 240 can be driven to the farthest position, that is, the movable roller 240 and the fixed roller 230 are at the maximum distance. In this way, it can be ensured that the wire can be completely received in the storage space 220 in the non-working state.

[0029] In some other embodiments, the slide bar 320 is slidably connected in the slideway 310 through a damping member. When the slide bar 320 is driven to slide by an external force, the movable roller 240 can be driven to move. When the external force is removed, the damping member can make the movable roller 240 maintain the state in which the external force makes it, so as to ensure that the distance between the fixed roller 230 and the movable roller 240 can be maintained. The damping member can be rubber that allows deformation or a gasket that increases friction.

[0030] It should be noted that in this embodiment, the fixed roller 230 does not move and the movable roller 240 moves. In some other embodiments, the fixed roller 230 and the movable roller 240 can be swapped, or both the fixed roller 230 and the movable roller 240 are allowed to slide, that is, at least one of the fixed roller 230 and the movable roller 240 is slidable.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
