Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of safety protection of loading and unloading vehicles, and in particular to a high-altitude falling prevention device for loading and unloading vehicles. Background Art
[0002] Truck loading and unloading operations span a wide range of industries, and loading is the first step before product transportation. Small-packaged products are often transported on flatbed trucks, but these lack safety rails, requiring loaders to stand on them to handle and organize the goods. While bulk cargo is loaded mechanically, manual tarpaulin lashing and covering are still required after loading. When fully loaded, the top of the cargo can exceed four meters above the ground, posing a risk of falls and seriously endangering the lives of truck operators. Therefore, protective measures are crucial for truck operators.
[0003] Currently, common fall prevention systems for loading and unloading vehicles include: a lifeline installed on the gantry, and a lifeline installed on the loading and unloading platform in conjunction with the gantry. These existing methods pose a risk of falling while climbing, and can also cause falls when the platform crosses over to the vehicle. Furthermore, the movement of workers during loading operations is restricted. Summary of the Invention
[0004] The technical problem to be solved by the utility model is to provide a high-altitude falling prevention device for loading and unloading vehicles, which can protect loading and unloading workers from climbing and the entire operation process, prevent people from falling from heights, and allow people to walk without restriction during the operation, making it easy to use.
[0005] The utility model provides a high-altitude falling prevention device for a loading and unloading vehicle, comprising a supporting mechanism and an anti-falling mechanism, wherein:
[0006] The support mechanism includes a set of bases, each of which has vertical pillars, a crossbeam connecting the tops of the two pillars, two ends of the U-shaped track connected to the upper parts of the pillars, at least one inclined beam connected to the crossbeam, and the other end of the inclined beam connected to the middle part of the U-shaped track;
[0007] The anti-fall mechanism comprises a moving trolley movably mounted on a U-shaped track, the moving trolley is connected to a fall arrester, and a hook is provided at the lower end of the fall arrester.
[0008] Preferably, a first pin seat is provided on the pillar, a second pin seat is provided on the U-shaped track, and a third pin seat is provided on the crossbeam. Both ends of the U-shaped track are installed on the first pin seat, and both ends of the inclined beam are respectively installed on the second pin seat and the third pin seat.
[0009] Preferably, a hanging ring is provided at the lower end of the pillar, and the hook can be hung on the hanging ring.
[0010] Preferably, the U-shaped track includes a hollow groove with an opening on the lower side, and walking support plates are horizontally provided on both sides of the opening.
[0011] Preferably, the mobile trolley includes an axle, and wheels are respectively equipped at both ends of the axle through bearings. The wheels can run on the walking support plate. The middle part of the axle is connected to the pull rod, the lower end of the pull rod is connected to the hook, and the fall arrester is hung on the hook.
[0012] Working principle of the utility model: The high-altitude fall prevention device for loading and unloading vehicles of the utility model, when in use, parks the vehicle to be loaded under the U-shaped track of the device, and the operator arrives on site after wearing a safety belt and connects the hook of the anti-fall device to the safety belt. Then the operator climbs the vehicle to perform the loading operation. As the operator moves, the mobile trolley moves within the U-shaped track. After the operation is completed and the operator gets off the vehicle, the anti-fall device hook is unhooked and hung on the hanging ring to fix it to prevent shaking and injuring people. In addition, by arranging pin seats on the columns, beams and U-shaped tracks, the U-shaped tracks and inclined beams are installed on the columns and beams using pins. After use, the pin on the second pin seat can be pulled out, so that the U-shaped track rotates around the pin on the first pin seat to a downward hanging state, and the inclined beam rotates around the pin on the third pin seat to a downward hanging state, thereby reducing the occupied space and facilitating the storage of the device.
[0013] The beneficial effects of the utility model are as follows: the anti-fall device for loading and unloading vehicles can protect loading and unloading workers from climbing and falling during the entire operation process, and can also be used without restrictions on movement. In addition, the device is easy to install and retract, saving storage space. BRIEF DESCRIPTION OF THE DRAWINGS
