Technical Field

[0001] This utility model relates to the field of crane technology, and in particular to a guide rail structure for an electric hoist bridge crane. Background Technology

[0002] The guide rail structure of an electric hoist bridge crane is a key component that supports and guides the crane trolley and the electric hoist. Its guide rails are typically made of high-strength steel and are installed above the main beam of the bridge frame, forming two parallel tracks. The guide rail structure must possess high precision, wear resistance, and stability to ensure smooth trolley operation and reduce swaying and deviation.

[0003] However, existing guide rail structures are usually located at high places, making daily inspection and maintenance inconvenient and making it difficult to detect potential problems such as cracks, rust, or loosening on the rail surface in a timely manner. At the same time, traditional guide rail structures lack support and are easily damaged when lifting heavy objects, resulting in poor stability and lifespan, and certain drawbacks in their use.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0009] Preferably, in order to enable the soft connecting block to rotate via the toothed belt, the soft connecting block is fixedly installed on the outer wall of the toothed belt.

Next, the mobile crane 3 is installed on the transverse slide rail 2 so that it can slide and run, while the electric hoist body 4 is fixed to the top of the mobile crane 3. The surround-type shooting and detection component 6 is fixedly connected to the mobile crane 3 and sleeved on the transverse slide rail 2 through the connecting strip 5, and is used for all-round detection of the transverse slide rail 2 and the reinforcing support block 7. This solves the problem of inconvenience in daily inspection and maintenance, and can detect problems such as cracks, corrosion or loosening on the track surface in time, and can replace the reinforcing support block 7 in time.

[0023] As a technical optimization solution of this utility model, specifically as follows: Figure 5 As shown, the surround-type imaging detection component 6 includes a first vertical mounting plate 601 and a second vertical mounting plate 602. The first vertical mounting plate 601 and the second vertical mounting plate 602 are respectively fixed to the connecting strips 5 at both ends.
