Description

Technical Field

[0001] The utility model relates to the technical field of protective doors, in particular to a multi-section folding protective door. Background Art

[0002] In industrial environments, a fence of about 2 meters is usually set up to separate the production line from other areas in the factory to prevent people from approaching the production line while it is in operation. If people approach the production line during operation, it may easily cause safety hazards. Protective doors are usually installed at the entrances and exits of the fence to meet the high-frequency and large-volume traffic needs.

[0003] For example, heliostat assembly lines require transporting heliostat backplanes and lenses to and from the production line. Existing fenced protective gates typically have pre-buried tracks in the ground or installed on top of the gate to ensure proper opening and closing. However, these tracks can hinder transport when raw materials enter or products leave the production line. Ground-level tracks can easily cause bumps in the transport vehicle, potentially damaging the mirrors. Meanwhile, overhead tracks restrict the height of cargo being transported in or out.

[0004] In addition, there are multiple automated robotic arms installed in the production line. If the production line is in operation and someone opens the protective door and approaches the production line, it may easily cause safety hazards. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The specific implementation of the present invention is described in detail below in combination with specific embodiments.

[0026] like Figures 1-6 As shown, the present invention provides a multi-section folding protective door, comprising a first column 6 and a third column 8, and a multi-section door body disposed between the first and third columns 6 and 8. The door body comprises a locking door 1, at least one movable door section, and a fixed door 5, arranged in sequence. The locking door 1, movable door, and fixed door 5 are connected to adjacent door bodies by upper tracks disposed transversely at the tops of adjacent door bodies and lower tracks disposed longitudinally at the bottoms of adjacent door bodies. This multi-section folding protective door is installed at the entrance and exit of the fence separating the production line, eliminating the need for additional tracks on the ground or on the top of the door body, effectively addressing the issue of tracks impacting the handling of products, raw materials, or equipment.

[0027] The width of the locking door 1 matches the width of the movable door. The width of the movable door and the locking door 1 and the number of movable doors can be designed according to the actual situation of the production line and the use requirements. This embodiment summarizes the utility model with a three-section movable door structure.

[0028] The locking door 1 can be locked in the first column 6 to close the protective door. A lock body 21 is provided in the first column 6.
