Novel hanging ring for fire-fighting descent control device

Abstract

The invention discloses a novel hanging ring for a fire-fighting descent control device. The hanging ring comprises an L-shaped plate; a right-angled plate is arranged on the top of the right side of the L-shaped plate; a twist drill is hinged to the outer end of a first straight plate body of the right-angle plate; the upper extending end, penetrating through the first straight plate body, of the twist drill is fixedly connected to an output shaft of an acceleration mechanism; an input shaft of the acceleration mechanism is fixedly connected to a first belt wheel; a mandril is fixed to the outer end of a second straight plate body of the right-angle plate; a second belt wheel is hinged to the upper extending end, penetrating through the second straight plate body, of the mandrel; the first belt wheel is connected to the second belt wheel through a belt; the second belt wheel is fixedly connected to a motor shaft of a motor; a transverse plate is fixedly arranged at the lower end of the L-shaped plate; two pressing rods are connected to the transverse plate in a threaded mode; a symmetric pressing rod is further arranged right above the pressing rod on the left side; and the pressing rod on the upper side is connected to the L-shaped plate in a threaded mode. The novel hanging ring has the advantages that a hole can be drilled in a balcony rapidly through the twist drill, and in addition, the hanging ring can be rapidly and stably fixed to the balcony through the mandril and the pressing rods.

Description

Technical field: [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a novel suspension ring for a fire-fighting slow descent device. Background technique: [0002] Fire Descending Device is composed of hook, sling, rope and speed control, etc. It is a safety rescue device that can make people descend slowly along the rope. It can be installed on building windows, balconies or flat roofs of buildings with special installation equipment, and can also be installed on elevating fire trucks to rescue victims in high-rise buildings on fire. However, one method of using the suspension rings for the existing fire-fighting descent devices is to hook them on the installation device, or to connect the suspension rings to the erected column-shaped fixtures through ropes. or in the case of columnar fixtures. Invention content: [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a new ...
