A fire-fighting ventilation duct construction lifting system

Abstract

The invention relates to the field of fire-fighting construction, and discloses a construction lifting system for fire-fighting ventilation pipes, which includes a box body and a lifting mechanism for lifting cargo boxes. An opening is provided on one side of the box body, a safety door is provided at the opening, and a safety door is provided on the inside of the box body. A container for fire-fighting facilities, a drive assembly is provided on one side of the container, the drive assembly includes a first drive member, a piston is provided at the output end of the first drive member, and a sealed pipeline assembly is provided on the side of the container away from the opening. The pipe assembly includes a drive tube, the drive tube is plugged with a sealed push tube, the piston is plugged into the inner side of the end of the push tube away from the drive tube, and the push tube is filled with liquid. When working, the first driving part drives the piston to move along the push tube and compresses the liquid in the drive tube. The liquid slowly pushes the drive tube to move, and then drives the cargo box to slowly move to the opening, reducing the driving vibration and avoiding fire hazards by virtue of the shape of the cargo box. The appliance falls to the ground from both sides, and the invention has the effect of improving the safety performance of the fire-fighting device.

Description

technical field [0001] The invention relates to the technical field of fire-fighting construction, in particular to a construction lifting system for fire-fighting ventilation pipes. Background technique [0002] Fire-fighting construction projects often require the use of lifting devices to lift fire-fighting facilities to the corresponding floors, and then carry out installation work. [0003] In the prior art, with reference to the Chinese utility model patent whose authorized notification number is CN209456013U, a hoist for fire engineering construction is disclosed, which includes two brackets, a first support plate, a first servo motor, a rotating rod, and a winding wheel , steel wire rope, box body, the first support plate is fixedly installed on the top of the two brackets, the first servo motor is fixedly installed on the top of the first support plate, and the rotating rod is fixedly installed on the output shaft of the first servo motor; The wire wheel is fixedly...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned existing technical solutions have the following defects: when the hoist is in use, the second servo motor needs to drive the screw to rotate, and then drive the second support plate to move to the opening, and then build a platform between the box body and the floor, so that Cover the gap between the box body and the floor, but in actual use, since there is no blocking mechanism on both sides of the second support plate, the fire-fighting facilities are easy to fall from the two sides of the second support plate; and the second servo motor Vibration will occur during the working process, which will easily cause the fire installation tools to shake and fall from a high place during the vibration process, which reduces the safety performance of the hoist
