Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically a windproof detection device for trackless gantry cranes. Background Technology

[0002] Gantry cranes are a type of bridge crane, also known as portal cranes. They are mainly used for loading and unloading goods and bulk materials in outdoor freight yards and material yards. The metal structure of a gantry crane resembles a portal frame, with two legs installed under the main beam, allowing it to travel directly on ground-level tracks. The main beam may have cantilever beams extending outwards at both ends. Unlike bridge cranes, gantry cranes are primarily used for outdoor work.

[0003] Application number "CN201220198176.9" discloses a windproof detection device for an outdoor crane, including two wind load simulation devices placed on two tracks, two force measuring devices, and one acceleration detection device. The wind load simulation device includes a support frame, a hydraulic jack, and an oil pump connected to the hydraulic jack via an oil pipe. The force measuring device includes a force sensor and a display instrument connected to it via a signal line. The acceleration detection device includes an acceleration sensor and a dynamic data acquisition device connected to it via a signal line. A force sensor is fixedly connected to the non-extended end of the piston rod of the hydraulic jack. The hydraulic jack and the force sensor are placed horizontally on the support frame. The acceleration detection device is placed on the crane. This utility model provides windproof detection for the entire machine, and its ingenious structural design makes it easy to use and carry, effectively solving the problem of not being able to monitor outdoor cranes in real time.
