Description

Technical Field

Bridge steel formwork, as a material made of steel ingots, steel billets or steel through pressure processing, is specially used for building railway or highway bridges. It is widely used in construction projects and plays an important role in the construction industry.

[0003] Flatness is one of the important indicators to measure the quality of bridge steel formwork. By testing the flatness, it is possible to promptly detect whether there are problems such as unevenness and bending on the formwork surface, so that appropriate measures can be taken to repair or replace it, ensuring that the quality of the final cast bridge structure meets the requirements and ensures the performance and safety quality inspection standards.

[0004] In the prior art, there is a bridge steel formwork flatness detection device, which includes a device body, and an additional frame is arranged on the device body, and the additional frame is extended upward.

A detector is also arranged on the additional frame, and the detection end of the detector is arranged vertically downward. When in use, the bridge steel formwork to be detected is placed on the device body, and then the sliding frame is moved so that the detector detects the area directly below the bridge steel formwork. After the detection of the area is completed, the bridge steel formwork is moved again to detect other areas.

[0005] Regarding the above-mentioned related technologies, when inspecting other areas of the bridge steel formwork, relevant personnel are required to manually move the bridge steel formwork so that other areas can be moved directly under the detector, which greatly increases the workload of relevant personnel, thereby reducing the efficiency of detecting the flatness of the bridge steel formwork, and thus it is difficult to adapt to the detection of the flatness of large-area bridge steel formwork, so it needs to be improved.

When the laying frame 41 rotates, so that the abutting roller 43 gradually lays the reflective film 221, the abutting roller 43 drives the connecting frame 251 to rotate together. At this time, the connecting frame 251 drives the linkage frame 252 to rotate, so that the length direction of the linkage frame 252 changes, and then the linkage frame 252 drives the mounting frame 24 to move downward, gradually approaching the bridge steel formwork below.

The marking strip 74 is made of sponge material, and the marking paint is adsorbed in the marking strip 74. The bottom surface of the bridge steel template is located on the displacement path of the marking strip 74, so that the position with insufficient flatness can be marked by gluing the marking paint to the corresponding position of the bridge steel template.

[0055] Reference Figure 1 , Figure 2 and Figure 4 Each detection member 224, adjustment member 62 and moving member 73 are electrically connected to the control member 225. A plurality of photosensitive points are arranged on the arc-shaped bottom wall of each detection member 224 to fully sense the reflected light. Each detection member 224 is used to receive the light reflected by the reflective film 221, and feed back the information of whether each photosensitive point receives the reflected light to the control member 225, so as to detect the deviation of the light reflected by the reflective film 221 by receiving the reflected light itself, and judge the flatness of the part at that place according to the specific photosensitive point receiving the reflected light, that is, the farther the photosensitive point receiving the reflected light is from the emitter, the greater the unevenness.

[0056] Reference Figure 1 , Figure 2 and Figure 4 The control member 225 is used to receive the information fed back by each detection member 224, and when there is a photosensitive point on any detection member 224 that receives reflected light, it is determined that the flatness of the part of the bridge steel template being detected is insufficient, and the moving member 73 is controlled to work, so that the moving member 73 drives the marking strip 74 to move upward and contact with the corresponding part of the bottom wall of the bridge steel template, so that the area is adhered with marking paint, thereby marking the position of the bridge steel template. Otherwise, it is determined that the flatness of the part is qualified, and the control member 225 controls the adjustment member 62 to work, drive the installation cover 222 to slide, thereby changing the position of the installation cover 222, and detecting another part of the bridge steel template.

[0057] The implementation principle of the bridge steel formwork flatness detection device of the embodiment of the present application is as follows: when in use, the rotating member 44 drives the laying frame 41 to rotate, so that the laying frame 41 drives the extension frame 421 to move, and then the abutting roller 43 lays the reflective film 221 on the bridge steel formwork. During the process, the laying frame 41 drives the mounting frame 24 to slide downward through the driving frame 4221, so that the mounting cover 222 is close to the reflective film 221.

[0058] Thereafter, the transmitter 223 emits a light for detection, and when the detection component 224 receives the light reflected by the reflective film 221, the control component 225 determines that the flatness of the part of the bridge steel formwork being detected is insufficient, and controls the moving component 73 to operate, so that the moving component 73 drives the marking strip 74 to move upward and contact with the corresponding part of the bottom wall of the bridge steel formwork, thereby marking the position of the bridge steel formwork at that place.
