Description

Technical Field

[0001] This utility model relates to track slab inspection, and in particular to track slab inspection fixtures. Background Technology

[0002] As a core load-bearing component of rail transit lines, the track slab's dimensional accuracy and structural integrity directly affect the safety and stability of train operation. During the production and maintenance testing of track slabs, rigorous verification of multiple indicators, including dimensional measurements and flatness checks, is required.

[0003] Existing methods for inspecting track slabs typically involve hoisting them using lifting equipment, such as overhead cranes, followed by inspection by personnel. However, track slabs are prone to swaying during hoisting, causing inconvenience for the inspection process. Furthermore, the weight of the track slabs and prolonged hoisting pose safety hazards. Therefore, after extensive research, the inventors have developed a track slab inspection fixture that addresses the issues of track slab structure, inspection requirements, and the slab's weight.

[0020] like Figure 1 and Figure 2As shown, the track slab inspection fixture includes a top support frame 1, which is a rectangular frame composed of two longitudinal support beams 11 and two transverse support beams 12. Support columns 3 are detachably installed at both ends of the longitudinal support beams 11. Limiting frames 5 are installed in pairs on the longitudinal support beams 11, and the limiting frames 5 have outwardly turned wedge-shaped surfaces. In this embodiment, both the longitudinal support beams 11 and the transverse support beams 12 are made of rectangular steel, and the longitudinal support beams 11 and transverse support beams 12 are welded together. After the top support frame 1 is supported by the support columns 3, the rectangular frame on the top support frame 1 is suspended. Therefore, when the crane hoists the track slab onto the top support frame 1, the bottom of the track slab is suspended, while the top, left, right, front, and rear sides of the track slab are exposed. Thus, the inspection personnel can easily inspect the track slab without having to flip or move it. Furthermore, the entire track slab is supported by the support columns 3, eliminating concerns about safety issues caused by track slab hoisting failure, thereby improving the safety of track slab inspection.

[0021] In this embodiment, as Figure 1 and Figure 2 As shown, the supporting longitudinal beam 11, supporting transverse beam 12, and supporting column 3 are all made of rectangular steel. Preferably, both ends of the supporting transverse beam 12 are located on the supporting column 3, so that the welding position of the supporting transverse beam 12 and the supporting longitudinal beam 11 is located above the supporting column 3. When the top supporting frame 1 bears the load, the reliability of the top supporting frame 1 can be guaranteed. Furthermore, the top of the supporting column 3 has a top plate, and a locking nut 7 is welded to the bottom of the top plate. Figure 5 As shown, both ends of the supporting longitudinal beam 11 have vertically protruding through holes, and locking screws 6 are installed in the through holes. The locking screws 6 are locked with the corresponding locking nuts 7. During installation, the locking screws 6 are inserted into the through holes, then the locking screws 6 and locking nuts 7 are aligned, and then the locking screws 6 are tightened, thereby realizing the detachable connection between the supporting column 3 and the supporting crossbeam 12. In this embodiment, to facilitate the installation of the locking screws 6, as shown... Figure 3 and Figure 4 As shown, a positioning hole 9 is also provided on the top plate. The positioning hole 9 is located on one side of the locking nut 7. The top of the support longitudinal beam 11 is welded with a positioning post 10 corresponding to the positioning hole 9. The positioning post 10 is installed in the corresponding positioning hole 9. During installation, the support longitudinal beam 11 is first lifted up, then the positioning post 10 is aligned with the positioning hole 9, and then the support longitudinal beam 11 is placed on the support post 3. Since the positioning post 10 is aligned with the positioning hole 9, the through hole and the locking nut 7 are aligned. Therefore, after the locking screw 6 is installed in the through hole, the locking screw 6 can be aligned with the locking nut 7, which makes it easy for the locking screw 6 and the locking nut 7 to be locked.

[0022] In this embodiment, as Figure 6As shown, the limiting frame 5 includes a limiting plate 21 and a guide plate 22. The limiting plate 21 is vertically installed on the supporting longitudinal beam 11. The top of the limiting plate 21 is connected to the guide plate 22. The guide surface of the guide plate 22 is a wedge-shaped surface, and the included angle α between the wedge-shaped surface and the limiting plate 21 is 30~45°. Preferably, the included angle α between the wedge-shaped surface and the limiting plate 21 is 30°. When the track plate is lowered, it can be placed in the designated position by the guidance of the guide plate 22, which facilitates the placement of the track plate.

[0023] In this embodiment, as Figure 2 As shown, the track slab inspection fixture also includes a bottom support frame 2, which is a rectangular frame. Support columns 3 are fixedly installed on the four corners of the rectangular frame. During installation, the bottom support frame 2 is placed on a flat surface. The reliability of the inspection fixture's support for the track slab is ensured by the support of the bottom support frame 2.

[0024] In this embodiment, as Figure 1 As shown, reinforcing ribs 8 are also installed between the supporting longitudinal beam 11 and the corresponding supporting column 3, thereby improving the structural strength of the track plate inspection fixture. Furthermore, the two opposite corners of the rectangular frame formed by the supporting crossbeam 12, the supporting column 3 and the bottom supporting frame 2 are connected by diagonal supporting beams 4, which further improves the structural strength of the track plate inspection fixture.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
