Description

Telescopic suspension frame for escape descent control device

Technical Field

The utility model relates to a high-rise escape auxiliary device, in particular to a telescopic suspension bracket for an escape descent control device.

Background

At present, the traditional fastening and hanging mode of the escape descent control device is generally that an indoor fixed hanging nose is fastened and hung, secondly that a firm indoor building component is fastened and hung, and thirdly that a large indoor article is fastened and hung; the common point of its use is that all can let slowly fall the ware at indoor position fixed, slowly fall the rope from indoor losing outside the window, then the person of fleing can grasp the rope of fleing and climb out of the window, and then just push the wall body or step on the wall body down after to avoid limbs scotch, waste time and energy, it is also inconvenient, consequently also make those who do not possess this kind climb the window and push away, step on the ability difficult to use.

Disclosure of Invention

In order to overcome the defects of the traditional bolting and hanging mode of the escape descent control device in the use of the escape descent control device, the utility model provides a telescopic suspension bracket for the escape descent control device, which consists of a fixed section, a telescopic section and a slide piece; the telescopic section is positioned in the fixed section, and the outer end of the telescopic section can extend out of a proper position outside the window when the telescopic section extends out; the fixed section and the telescopic section of the suspension bracket are provided with slideways, and the telescopic section can enter and exit along the slideways in the fixed section; the slider is hung on the telescopic section and can slide along the slide way in the telescopic section, the lower part of the slider is provided with a descent control device hanging nose, and the slider can slide along the track of the telescopic section and can enter and exit the fixed section along with the telescopic section; the suspension bracket has the remarkable characteristics and functions that: a moving channel from indoor to outdoor is constructed through the fixed section and the telescopic section, so that the suspended escape device has a walking interval; the hanging frame is matched with the escape descent control device, so that the descent control device can slowly descend from indoor to outdoor when people are carried to a set barrier-free descending space, and the escape purpose is achieved; meanwhile, the limbs of the person are not in contact with the window body and the wall body, so that barrier-free movement is realized, and time, labor and convenience are realized; even if people lack behavior ability, people can safely escape as long as people fasten the slow descending rope indoors and control the slow descending rope and the locking device; therefore, the telescopic suspension bracket is matched with the escape descent control device for use, so that the adaptive population of the escape descent control device can be expanded.

The utility model discloses the scheme that technical adoption was used to slowly descend the ware of fleing is: constructing; the telescopic suspension bracket is composed of a fixed section, a telescopic section and a slide piece. The fixed section and the telescopic section are both square tubular bodies, are thick and thin and belong to a sleeving structure, and the telescopic section can freely enter and exit; a sliding piece inlet and outlet opening is arranged below the fixed section, a positioning convex opening is arranged on the upper surface of the fixed section along the middle of the tube, a locking hole is arranged below the inner end of the fixed section, fixing lugs are respectively arranged above two ends of the fixed section, and the fixing lugs are integrated with the tube wall through welding; a sliding opening of the sliding piece is arranged below the telescopic section, a positioning protrusion is arranged above the inner end of the telescopic section, an auxiliary locking nose is arranged above the positioning protrusion, and the positioning protrusion is fixed with the pipe wall through a screw and locked through a locking pin; the outer end pipe head of the telescopic section is sealed by welding, and the inner end pipe head of the telescopic section is sealed by a pipe plug through a screw; a plurality of roller groups are arranged on the left side and the right side of the telescopic section, each roller group consists of a vertical wheel and a small transverse wheel, the transverse wheel is arranged at the outer end of a wheel shaft of the vertical wheel, and the inner end of the wheel shaft of the vertical wheel is welded with the square tube of the telescopic section into a whole; except that the left and right roller groups at the inner end of the telescopic section are arranged close to the upper part, the other roller groups are arranged close to the lower part; the two rows of roller groups are arranged at the lower part of the telescopic section close to the inner end, the precondition is that the telescopic section does not depart from the outer end of the fixed section when extending out, and the setting density of the roller groups is the precondition that the telescopic section main body does not directly generate friction with the fixed section main body; the slider is positioned on the sliding way of the telescopic section, the left side and the right side of the slider are provided with roller groups, the roller groups are arranged in a row respectively in front and at back, the inner ends of the wheel shaft of the wheel groups in the vertical direction are welded with the slider into a whole, the outer end of the lower part of the slider is provided with a descent control device suspension nose, the inner end of the lower part of the slider is provided with a locking hook which is combined with the lower part of the slider through a bolt shaft, the locking hook can freely rotate around the axis of the bolt shaft, the lower part of the hook head of the locking hook is provided with an auxiliary unlocking nose, a traction rope can be tied on the unlocking nose, and the other end of the traction rope can be fixed indoors; the extension length of the telescopic section is based on the premise that the escaper does not touch the wall body when slowly descending by using the descent control device.

The installation requirement is as follows: the stretching direction of the telescopic section of the suspension bracket is the outer end and is pointed to the outside of the window, the inner end of the fixed section of the suspension bracket is higher than the outer end by the middle position of the lower part of the upper threshold of the window, a certain gradient is formed, the size of the gradient can be used as a precondition that the telescopic section and the slider can slide to the set position outside the window under the action of gravity after the locking hook is loosened, the gradient cannot be overlarge, and otherwise the stability of the sliding-out process can be influenced.

The working principle is as follows: when the suspension bracket is in a standby state, the escape descent control device is completely locked, suspended on the suspension bracket and in a manned state, when the locking hook is released, the telescopic section and the slide piece suspended with the descent control device can slide outwards due to the existence of gradient and gravity, the sliding can stop at a set position due to the existence of the sealing and positioning protrusions of the tube head of the telescopic section, the suspended descent control device is positioned at the outer end of the telescopic section of the suspension bracket, and then the escaper releases the descent control rope to realize descent control; and (4) returning the telescopic section: the slider is pulled through the pulling rope to drive the telescopic section to move inwards, and when the locking hook moves to the locking hole of the fixed section, the telescopic section and the slider are locked simultaneously because the gravity locking hook of the locking hook handle is automatically buckled.

The telescopic suspension frame for the escape descent control device has the obvious advantages in application that: through the use of the hanging frame and the descent control device in a matched manner, the escape mode that the traditional escape descent control device is fixedly hung indoors and slowly descended by people climbing a window and climbing a buttress is changed into the escape mode that people slide outdoors along with the descent control device hung on a track and slowly descend in an unobstructed downlink space, and the escape descent control device becomes more practical.
