Fire escape, exterior wall cleaning, climbing multi-functional and simple lifter

Abstract

The invention discloses a multifunctional simple and convenient lifter used for fire disaster escape, outer wall cleaning and climb. Two seamless steel tubes are adopted as a left and a right frame; rotating shaft grooves, drag hook grooves, moving shaft grooves and push plate grooves are formed in the same horizontal planes of the inner sides of the left and right frames; a through hole is formed in the upper front face of each frame; the centre lines of the holes are vertical to the center lines of the grooves; a rotating shaft, a drag hook and torsion springs are respectively placed in the corresponding grooves and are riveted into a whole by rivets;a forming rolling wheel is sleeved on the rotating shaft; a groove and a boss are arranged on the other end of the rotating shaft, and are tightly matched with a boss and a groove arranged on one end of the drag hook under the tension of the coaxial torsion springs; a rolling wheel pair is matched with the rolling wheel. A steel plate is bent into four siamesed circles, wherein the first circle is the rolling wheel pair, the second and third circles at two sides of the first circle penetrate through a moving shaft, two ends of the moving shaft are respectively sleeved in the rotating shaft grooves of the frames and are matched with connecting rod round heads in the frames, the moving shaft can be rotated in connecting rod round head holes, the fourth circle is used as a handle, and a lower limit plate is arranged below the handle; springs and retainers are mounted in forming holes in the lower ends of the frames; an upper push plate and steel balls are mounted on the upper ends of the retainers; taper sleeves are mounted on the excircles of the retainers; notches are formed in the inner sides of the frames at the bottoms of the taper sleeves; a connecting plate is mounted in the notches; the tail ends of the connecting plate are inwards folded and riveted, and the periphery of the connecting plate is fully welded.

Description

Technical field [0001] The invention relates to fire protection, environmental protection, and climbing, in particular to a multifunctional and simple lifter for fire escape, outer wall cleaning, and climbing. Background technique [0002] Among the currently known fire-fighting equipment, there are many public welfare ones. In case of a fire, there are very few escape equipment used by urban residents. Wall curtains such as high-rise shopping malls are often cleaned with single-rope suspension. Mountain climbers use a lot of equipment, but most of them can go down but not up, and the descent is slow by manual control. Contents of the invention [0003] In order to overcome the disadvantages of the above problems, the present invention provides a multi-functional and simple lifter for fire escape, exterior wall cleaning and climbing. [0004] The technical solution adopted by the present invention to solve the technical problem is: adopt two seamless steel pipes as the le...

Problems solved by technology

[0002] Among the currently known fire-fighting equipment, there are many public welfare ones. In case of a fire, there are very few escape equipment used by urban residents. Wall curtains such as high-rise shopping malls are often cleaned with single-rope suspension. Mountain climbers use a lot of equipment, but most of them can go down but not up, and the descent is controlled by hand and the intermittent descent speed is slow. The rope goes through multiple loops, which causes a lot of fatigue and wear
