Description

Technical Field

[0001] The utility model relates to the technical field of bridge detection, in particular to an internal track support structure of a steel structure bridge tower. Background Art

[0002] With the increasing speed of development of intelligent equipment and its increasing intelligence, more and more intelligent equipment is being put into use in structural inspection. The steel structure bridge tower is a box-section. In order to improve the overall stiffness of the bridge tower structure, the entire box is usually further divided into several boxes, so that its cross section constitutes a single-box multi-type structure. Therefore, the activity space inside the steel structure bridge tower is very narrow. In the larger box, a large number of horizontal and vertical stiffening ribs are arranged on the surrounding walls to further strengthen the box locally. In the smaller box, its own stiffness has met the structural stability requirements, so the surrounding walls are relatively smooth. In addition to the stiffening ribs, transverse partitions are also set at a certain distance inside. The complex structural features inside the box seriously hinder the inspection personnel from entering the box to carry out structural maintenance operations, and also cause great interference to the installation and normal operation of commonly used intelligent equipment. In order to enable the inspection robot to run smoothly in the structure, avoid obstacles and carry out inspection operations smoothly, a fixed track is used to limit the movement trajectory of the inspection robot. However, the internal structural characteristics of the steel structure bridge tower make it impossible for the existing track support method to be stably installed in the above-mentioned inspection environment. At the same time, due to the size of the internal space of the bridge tower and its towering structural conditions, large construction equipment cannot be carried into the bridge tower, and the construction methods commonly used with track support are further restricted. The stable support of the track plays a decisive role in the smooth movement and precise operation of the inspection equipment.

[0003] There are two main ways to lay narrow tracks, namely welding with the structural surface and drilling holes on the structural surface and bolting. The support connection method of welding with the structural surface requires professional welding equipment and an open air circulation environment to remove welding exhaust gas in time. In addition, the new weld will cause certain damage to the original structure. In the high-rise bridge tower structure, the internal space is small, and the closed and unventilated environment is not suitable for track support inside the steel structure bridge tower. Compared with the welding method, drilling holes on the structural surface and bolting with bolts avoids the generation of exhaust gas, but the secondary construction of the structural surface greatly destroys the mechanical properties of the original structure on the one hand, and greatly reduces the construction efficiency on the other hand, which is time-consuming and labor-intensive. Another fatal engineering problem is that drilling holes on the structural surface greatly reduces the installation accuracy of the track, greatly increases the difficulty of manufacturing and construction of components, and is also not suitable for track support inside steel structure bridge towers. However, in some specific structural steel bridge towers, once the steel structure is built, secondary construction is usually not allowed on the structure. Secondary construction on the steel structure is very likely to cause changes in the structural properties and shorten the service life of the structure.

[0004] In view of this, it is necessary to propose an internal track support structure of a steel structure bridge tower to solve the above defects. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides an internal track support structure of a steel structure bridge tower, including a clamping frame, a supporting frame and a connecting frame. Clamping openings are formed at both ends of the clamping frame. The clamping frame passes through the manhole bracket and the clamping openings at both ends clamp the edge of the manhole bracket. One end of the supporting frame is fixedly connected to the track, and the other end is connected to the clamping frame through the connecting frame.

[0024] Please refer to Figure 1 and Figure 2 The utility model provides a steel structure bridge tower internal track support structure. The steel structure bridge tower internal track support structure comprises a clamping frame 1, a support frame 3 and a connecting frame 5. The two ends of the clamping frame 1 form clamping openings 6. The clamping frame 1 passes through a manhole bracket 9 and the clamping openings 6 at both ends clamp the edge of the manhole bracket 9 to be fixed on the manhole bracket 9. One end of the support frame 3 is fixedly connected to the track 7, and the other end is connected to the clamping frame 1 through the connecting frame 5. The clamping frame 1 is set to clamp the edge of the manhole bracket, and then the track 7 is connected to the clamping frame 1 through the support frame 3 and the connecting frame 5, so that the track 7 is effectively connected between the manholes, without welding, avoiding the waste gas generated in the welding process, and reducing the construction difficulty. The structure of the clamping frame 1 avoids secondary construction inside the steel structure, while enhancing the support rigidity and stability, greatly improving the construction efficiency, and the installation of the clamping frame 1 also provides a construction and installation accuracy margin.

[0025] Specifically, in this embodiment, the clamping frame 1 includes an upper clamping plate 11, a lower clamping plate 13, a fastener 15 and a fixing plate 16. The upper clamping plate 11 passes through the manhole of the manhole bracket 9. The lower clamping plate 13 and one end of the upper clamping plate 11 are connected by the fixing plate 16, and the other end forms the clamping opening 6 to clamp the manhole bracket 9. The upper clamping plate 11 and the lower clamping plate 13 are arranged at intervals, and the fastener 15 passes through the upper clamping plate 11 and the lower clamping plate 13 to position the clamping opening 6. It should be explained that the clamping opening 6 is a free end formed by the other end of the upper clamping plate 11 and the lower clamping plate 13. The clamping opening clamps the manhole bracket 9, and the clamping force is adjusted by adjusting the fastener 15.

[0026] The upper clamping plate 11 is a whole plate, and the lower clamping plates 13 are two. The two lower clamping plates are connected to the two ends of the upper clamping plate 11 through the fixing plate 16, respectively. The upper clamping plate 11 and the two lower clamping plates 13 respectively clamp the two opposite edges of the manhole bracket 9. One upper clamping plate 11 and the two lower clamping plates 13 form two clamping openings, which are clamped from the two edges of the manhole bracket 9 so that the clamping frame 1 is effectively connected. In this way, the track 7 connected to the clamping frame 1 through the support frame 3 and the connecting frame 5 can be effectively fixed.

[0027] Specifically, in this embodiment, the fastener 15 is a bolt. The bolt passes through the upper clamping plate 11 and the lower clamping plate 13 to connect the two. Before the connection and fixing, the bolt pre-connects the upper clamping plate 11 and the lower clamping plate 13, and is easy to disassemble. The mechanical properties of the internal structure of the steel structure bridge tower will not be damaged by the bolt connection.

[0028] The lower clamping plate 13 is provided with a mounting hole 131, and the mounting hole 131 is a straight slot type. The fastener 15 passes through the upper clamping plate 11 and the mounting hole 131 to connect the upper clamping plate 11 and the lower clamping plate 13. The mounting hole 131 is a straight slot type, and its length direction is arranged along the length direction of the track 7. The advantage of setting the straight slot type mounting hole 131 is that during the installation process, the position of the lower clamping plate 13 can be adjusted to offset the error generated during the installation of the track 7, ensuring that the clamping frame 1 can be clamped with the edge of the manhole, thereby improving the installation flexibility of the structure. Therefore, the adjustable range during the installation of the structure is large, and the fault tolerance for track installation is strong.

[0029] like Figure 2As shown, further, the clamping frame 1 further includes a height limiting block 17, one end of which is fixed on the lower clamping plate 13, and the other end is inserted into the upper clamping plate 11. It can be understood that an insert block is provided on the end of the height limiting block 17 away from the lower clamping plate 13, and an assembly hole is provided on the upper clamping plate 11. The lower clamping plate 13 is inserted into the assembly hole on the upper clamping plate 11 through the insert block to connect the two. The function of the height limiting block is to limit the height between the upper clamping plate 11 and the lower clamping plate 13 to prevent the fastener 15 from being over-tightened or over-loosened.

[0030] One end of the support frame 3 is connected to the track 7, and the other end is connected to the connecting frame 5. A slide groove 31 is provided on the support frame 3 along the length direction of the track 7. The connecting member passes through the connecting frame 5 and the slide groove 31 to connect the connecting frame 5 to the support frame 3. The connecting frame 5 can be moved along the slide groove 31 to adjust the position, so that the relative position relationship between the clamping frame 1 and the support frame 3 can be adjusted, so that the installation flexibility of the structure is higher.

[0031] Specifically, in this embodiment, the connecting member is a bolt, which passes through the connecting frame 5 and the slide slot 31 to connect the connecting frame 5 to the supporting frame 3, so as to facilitate disassembly.

[0032] The internal track support structure of the steel structure bridge tower provided by the utility model is clamped on the edge of the manhole bracket by the set clamping frame 1, and then the track 7 is connected to the clamping frame 1 through the support frame 3 and the connecting frame 5, so that the track 7 is effectively connected between the manholes, without welding, avoiding the waste gas generated in the welding process, and reducing the construction difficulty. The structure of the clamping frame 1 avoids secondary construction inside the steel structure, enhances the support stiffness and stability, and greatly improves the construction efficiency. Moreover, the installation of the clamping frame 1 also provides a construction and installation accuracy margin, is simple to install, does not need to carry large equipment, and also has good economic benefits.

[0033] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
