Description

Technical Field

[0001] This utility model relates to the field of dock crane lane technology, specifically to a dock crane lane. Background Technology

[0002] During shipbuilding and repair, cranes are needed to transport steel, parts and other materials vertically and horizontally to solve the problems of low efficiency and high risk of manual handling. The use of cranes requires the laying of crane lanes in the dock.

[0003] Currently, existing dock crane lanes require regular inspections to ensure their structural stability and prevent localized micro-deformation of the rails due to heavy loads or fatigue, which could affect the crane's operational stability. This process is quite labor-intensive and resource-intensive. In addition, the existing crane lane paving project is relatively complex, and the stability of the lane joint connections is poor, which affects the service life of the lanes.

[0004] Based on this, the present invention designs a crane lane for docks to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a crane lane for docks.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a crane track for a dock, comprising a track, a first fixing bolt, a connecting beam, a second fixing bolt, a fiber optic strain sensor, a fiber optic connector, and a connecting fiber. A groove is provided at the upper end of the track, and a fiber optic strain sensor is pre-embedded in the groove. Both ends of the fiber optic strain sensor are fixedly connected to fiber optic connectors. The fiber optic connectors can be connected to the fiber optic connector at one end of another fiber optic strain sensor via the connecting fiber. An I-beam connecting block is provided at one end of the track, and a connecting groove is provided at the other end of the track. The connecting groove has the same shape and size as the I-beam connecting block.

[0007] As a preferred embodiment of this utility model, the fiber optic connectors at both ends of the fiber optic strain sensor are embedded inside the upper end of the track.

[0008] As a preferred embodiment of this utility model, the bottom of the track is symmetrically provided with protruding edges, and multiple mounting holes are equally spaced on the protruding edges.

[0009] As a preferred technical solution of this utility model, multiple fixing plates are equidistantly arranged on the convex edges on both sides of the track, and each fixing plate is provided with a first fixing bolt. The two sides of the track are fixedly connected to the foundation through multiple first fixing bolts.

[0010] As a preferred technical solution of this utility model, a plurality of connecting beams are provided between the two tracks, and each of the connecting beams has a slot at both ends, which engages with the protruding edge at the bottom of the track.

[0011] As a preferred embodiment of this utility model, the two ends of the connecting beam are respectively fixedly connected to the two rails by second fixing bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model involves creating a groove on the upper surface of the track and embedding a fiber optic strain sensor along the track within the groove. The fiber optic strain sensor can detect changes in rail stress in real time and provide early warning of micro-deformation of the track. At the same time, it can analyze low-frequency vibration signals during crane acceleration or braking to provide early warning of loose track bolts or fatigue of connectors, facilitating timely warning of crane track issues. Furthermore, the segmented pre-embedded fiber optics facilitate the location of problematic tracks, enabling timely repair and replacement of the tracks.

[0014] 2. This utility model uses an I-beam connecting block at one end of the track to mortise and tenon with a connecting groove at the other end of the track, which facilitates the quick assembly of the two track sections. Then, the connection is further reinforced by a seamless welding process, which makes the track connection more stable. At the same time, the track joint is stable and not easy to loosen during the welding process, which improves the welding quality, ensures smooth track joints, reduces the risk of cracking, and thus extends the service life of the track.

[0024] The following will refer to the appendix in the embodiments of this utility model. Figure 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example

[0026] Please see Figure 1-7 The present invention provides the following technical solution: a crane track for a dock, comprising a track 1, a first fixing bolt 2, a connecting beam 3, a second fixing bolt 4, a fiber optic strain sensor 5, a fiber optic connector 6, and a connecting fiber optic cable 7. The upper end of the track 1 is provided with a groove 103, in which a fiber optic strain sensor 5 is pre-embedded. Both ends of the fiber optic strain sensor 5 are fixedly connected to fiber optic connectors 6. The fiber optic connectors 6 can be connected to the fiber optic connectors 6 at one end of another fiber optic strain sensor 5 through the connecting fiber optic cable 7. One end of the track 1 is provided with an I-shaped connecting block 101, and the other end of the track 1 is provided with a connecting groove 102, which has the same shape and size as the I-shaped connecting block 101.

[0027] The fiber optic connectors 6 at both ends of the fiber optic strain sensor 5 are embedded inside the upper end of the track 1.

[0028] The fiber optic strain sensor 5 installed inside the upper end of track 1 can monitor the stress changes and low-frequency vibration signals of the track during use, thereby providing early warning of micro-deformation of the track or loosening of bolts, facilitating timely maintenance of the track and improving safety.

[0029] The bottom of the track 1 is symmetrically provided with a raised edge 104, and multiple mounting holes 1041 are equally spaced on the raised edge 104.

[0030] Multiple fixing plates 105 are equidistantly arranged on the protruding edges 104 on both sides of the track 1. Each fixing plate 105 is equipped with a first fixing bolt 2. Both sides of the track 1 are fixedly connected to the foundation through multiple first fixing bolts 2.

[0031] Multiple connecting beams 3 are provided between the two tracks 1. Each end of the connecting beam 3 is provided with a slot 301, which engages with the protruding edge 104 at the bottom of the track 1.

[0032] The two ends of the connecting beam 3 are fixedly connected to the two rails 1 by the second fixing bolts 4 respectively.

[0033] The detachable design of the connecting beam 3 facilitates connection with the track 1 and enhances the stability between the two tracks 1. The symmetrically arranged protruding edges 104 at the bottom of the track 1 increase the contact area between the track 1 and the base surface, thereby enhancing stability.

[0034] The working principle and usage process of this utility model are as follows: In specific use, the two rails 1 are fixedly connected together by the connecting beam 3 and the second fixing bolt 4 to form a crane lane. Then, the combined lane is placed in the predetermined installation position, so that the fixing plate 105 corresponds one-to-one with the pre-drilled positioning holes. Then, multiple first fixing bolts 2 are screwed into the positioning holes through the fixing plate 105 to realize the installation and fixation of the crane lane. When connecting the two lanes, the I-shaped connecting block 101 at one end of the two rails 1 of the other lane is tenoned with the connecting groove 102 at one end of the fixed lane. Then, the tenon joint is welded and fixed by seamless welding process and ground to further strengthen the connection of the lane. Then, the extended lane is fixed. In use, the fiber optic strain sensor 5 laid in the groove 103 at the upper end of the rail 1 can detect the change of rail stress in real time, and warn of rail micro-deformation, rail bolt loosening or connector fatigue. The crane lane can be inspected in advance to avoid the impact of local micro-deformation of the rail due to heavy load or fatigue on the stability of crane operation.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
