Push-pull automatic opening leaflet

Abstract

The invention relates to a push and pull type small blade plate capable of being automatically started. The push and pull type small blade plate capable of being automatically started is used for a full-automatic cover plate. The push and pull type small blade plate capable of being automatically started is characterized in that the push and pull type small blade plate comprises a small blade plate body, a turning transmission device, a synchronous transmission device and a driving cylinder; the small blade plate body comprises at least one sheet bar which is in end-to-end sequential connection; each sheet bar is provided with at least one turning transmission device driving the sheet bar to be opened and closed; and all the turning transmission devices are connected with the driving cylinder through the synchronous transmission device, and the driving cylinder is used for providing power for making the small blade plate body opened and closed. The push and pull type small blade plate capable of being automatically started is ingenious and reasonable in structure, high in automation degree, capable of achieving a one-key type opening and closing control mode and achieving remote control, and high in safety performance.

Description

technical field [0001] The invention relates to an accessory part on a safety protection device for a hanging object hole, in particular to a push-pull type automatic opening small leaf plate used for a fully automatic safety cover plate, which belongs to the technical field of mechanical equipment. Background technique [0002] Safety protection equipment is required on equipment lifting holes or inspection holes in multi-storey buildings, such as: hydroelectric power plants, thermal power plants, steel plants and some enterprises. Such lifting holes and inspection holes are usually covered with steel cover plates or Permanent guardrails are installed around the hole. When it is necessary to lift the equipment or maintenance equipment on the middle and lower floors of the building, it is necessary to lift the steel cover plate and set up a temporary fence. When working, use lifting equipment such as cranes or winches; the workload is large and requires the assistance of mult...

Problems solved by technology

[0002] Safety protection equipment is required on equipment lifting holes or inspection holes in multi-storey buildings, such as: hydroelectric power plants, thermal power plants, steel plants and some enterprises. Such lifting holes and inspection holes are usually covered with steel cover plates or Permanent guardrails are installed around the hole. When it is necessary to lift the equipment or maintenance equipment on the middle and lower floors of the building, it is necessary to lift the steel cover plate and set up a temporary fence. When working, use lifting equipment such as cranes or winches; the workload is large and requires the assistance of multiple people; Poor decoration, uncoordinated with the overall environment, not beautiful; there are potential safety hazards

Today, with the rapid development of automatic control technology, the entire hydropower station and thermal power plant have begun to realize unattended or less-attended operation. If the previous safety protection equipment for hanging objects is still used, a large number of manpower will still be required, which is not in line with modernization. Enterprise development needs
