Description

Technical Field

[0001] The present application relates to the technical field of detection devices, and more specifically, to a span measurement and detection device. Background Art

[0002] In the field of bridge engineering, calculated span is a key concept. For bridge structures with supports installed, the calculated span refers to the horizontal distance between the center points of adjacent supports in the span structure. For bridges without supports, such as arch bridges or rigid frame bridges, the calculated span refers to the horizontal distance between the center points of the intersection of the superstructure and the substructure. This parameter plays an important role in the stress analysis of bridges. When designing bridges, the calculated span is an important basis for determining the size and structural strength of the bridge. For bridges with supports, engineers need to accurately measure the horizontal distance between the center points of adjacent supports to ensure that the bridge can withstand the expected load, and a total station is needed to detect and measure the span.

[0003] The document with the prior art announcement number CN221611056U provides an adjustment bracket and a total station. By installing the total station body on a lifting support mechanism with a telescopic function, the height of the total station body can be adjusted through the lifting support mechanism during use; the lifting support mechanism is then installed on the lifting support leg mechanism, and the lifting support leg mechanism is provided with at least three, and the length of each lifting support leg mechanism is adjusted separately, so that the adjustment bracket can keep the total station body balanced on uneven ground; and the adjustment bracket can adjust the height of the total station body through the lifting support mechanism, and can also adjust the height and angle of the total station body by adjusting the corresponding lifting support leg mechanism, so that the total station body can be effectively used under different terrain conditions.

[0004] Although this device has many beneficial effects, the following problems still exist: when workers use a total station to perform span detection outdoors, due to temperature differences, fog is easily generated on the lens of the total station eyepiece, affecting the user's observation and thus easily affecting the accuracy of the measurement results. In view of this, we propose a span measurement and detection device. Utility Model Content

The air outlet end of the air pump 33 is fixedly connected to a connecting pipe 34, and one end of the connecting pipe 34 is fixedly connected to a connecting tube 35. A plurality of nozzles 36 are fixedly connected to one side of the connecting tube 35, so as to facilitate the rapid defoggering of the eyepiece of the total station 4.

[0031] Reference Figure 1 and Figure 2 A slide groove is provided on the outer wall of the mounting plate 2, and a slider 32 is fixedly connected to the side of the rotating plate 31 close to the mounting plate 2. The slider 32 is slidably connected to the slide groove, so that the staff can adjust the position of the rotating plate 31 to defog both lenses of the eyepiece.

[0032] Reference Figure 1 and Figure 2 A support plate 39 is fixedly connected to the top of the rotating plate 31 , and the top of the support plate 39 is fixedly connected to the top of the connecting tube 35 , so as to improve the stability of the connecting tube 35 .

[0034] Reference Figure 1 and Figure 2 , there are sockets on all four sides of the top of the mounting plate 2, and a fixing plate 37 is fixedly connected to one side of the support plate 39. A plug rod 38 for cooperating with the socket is slid through the top of the fixing plate 37, so as to facilitate the positioning of the rotating plate 31 and fix the rotating plate 31 at a position away from the eyepiece of the total station 4 to prevent the support plate 39 and the connecting tube 35 from blocking the eyepiece and affecting the measurement work of the staff.
