Description

Technical Field

[0001] The utility model relates to the technical field of steel structure transportation, in particular to a device for transporting building steel structure fittings. Background Technique

[0002] When transporting steel components, a trolley is mostly used to transport the steel components within a small range.

[0003] The Chinese patent discloses a device for transporting steel structure components, with the publication number CN113682359A, which includes a support frame assembly. A component fixing mechanism is fixedly installed inside the support frame assembly. A buffer mechanism is fixedly installed on the outer wall of the bottom of the support frame assembly. Four groups of universal wheels are fixedly installed around the outer wall of the bottom of the buffer mechanism. A push-pull rod is fixedly installed on the outer wall of the left side of the buffer mechanism. The support frame assembly includes a support frame, a first fixed plate moving groove, a second fixed plate moving groove, a first limiting slide rod, and a second limiting slide rod. For the device for transporting steel structure components of the present invention, through the provided component fixing mechanism, the components are firmly fixed in the middle of the support frame, and at the same time, the center of gravity of the entire transportation is kept in the middle, making the transportation more stable; through the provided buffer mechanism, when the support frame assembly generates a downward pressure during operation, the spring compresses to buffer the downward pressure generated by the buffer support plate, making the rotation more stable.

[0004] However, it still has the following disadvantages: When placing the steel structure between the vertical fixing mechanism and the horizontal fixing mechanism, an external lifting device is required to lift the device, making the loading and unloading process not convenient enough. For this reason, we propose a device for transporting building steel structure fittings to solve this problem. Content of the Utility Model
