Abstract
The overhead life preserver consists of hook, descent rope, control box, safety belt and reducing valve. In the limiting device, the lower end of the moving brake block holder is embedded by the shaft in the lower end of the casing, the moving and static brake blocks are opposite each other, and their upper parts are pushed by the spiral spring to the opposite of the casing and connected to the lower end of the brake handle. The descent rope passes through the upper and the lower sleeves and the moving and static brake blocks. The reducing valve is hung on the lower end of the descent rope. The present invention is used in self-salvage of personnel in high-rise building in case of fire, earthquake and other emergency.
Description
The invention belongs to and be in decline self-help apparatus when in the high-rise emergency taking place.
Existing high-altitude decline self-rescuer ubiquity complex structure enters this device trouble, is rescued personnel such as ability out of hand, tumble injury when easily being dropped to ground fast.
The objective of the invention is to develop a kind of overhead life preserver, this brucker survival capsule should have simple in structure, is rescued the personnel oneself and just can enter this device, even it is also unlikely by tumble injury to lose self-control.
The present invention is made up of hook, decline rope, control cabinet, safety belt, pressure-reducing valve.The lower end of hook is fixed on the upper end of decline rope, and the upper end of hook is fixed on the building at people place.Pressure-reducing valve hangs solid lower end at the decline rope.Control cabinet is made up of brake lever, sleeve, housing, speed-limiting device, and speed-limiting device is made up of quiet brake lining, moving brake lining, brake lining frame, spring.The sound brake lining is all manufactured by elastic caoutchouc or wear-resistant plastic, and quiet brake lining is fixed on the quiet brake lining frame, and quiet brake lining frame is fixed on the interior side of housing.The moving sheet of explaining is fixed on the moving brake lining frame, and the lower end of moving brake lining frame is set in lower end in the housing by axle, and the sound brake lining in opposite directions and right.The upper outside of moving brake lining frame withstands on the opposite of housing by a helical spring, and the top of moving brake lining frame links to each other with the lower end of brake lever.Sleeve is made up of two parts up and down, and upper bush is fixed near covering in the quiet housing upper shed of explaining the sheet place, and lower sleeve is fixed on the going to the bottom of close quiet brake lining place housing under shed, and the top of brake lever is exposed by the opening part of case top lid.The decline rope is by in the upper bush, between the sound brake lining, pass in the lower sleeve.Safety belt is made up of waistband, kicking strap, and kicking strap is a herringbone, and the following two ends of herringbone are connected with the middle part of waistband, and a hook is with in the upper end of herringbone, is used to hang over the front portion of waistband.There is a loose joint that is used to lock at the two ends of waistband.One end of waistband is hung in the hook that the control cabinet housing goes to the bottom by a rope.Pressure-reducing valve by a cylindrical shell, loam cake, go to the bottom, helical spring forms, go to the bottom and be fixed on the lower end of cylindrical shell, helical spring lower end is fixed on the going to the bottom in the cylindrical shell, helical spring upper end is fixed on the end of decline rope, loam cake is enclosed within on the cylindrical shell, and the internal diameter of cylindrical shell is greater than the external diameter that is fixed on the lower sleeve on the housing.
When the present invention can be used for unexpected burst accident such as fire, earthquake and takes place, be in saving oneself of personnel in the high-rise.As long as the people fastens seat belts the pulling brake lever control decrease speed well just can safe landing, even people's stupor or brake failure also can safe landings in descending.It has simple in structure, be convenient and swift, advantage that cost is low.
Fig. 1 is an overall structure schematic diagram of the present invention, and Fig. 2 is the A-A cutaway view of Fig. 1, and Fig. 3 is the structural representation of stopping means, and Fig. 4 is the structural representation of pressure-reducing valve, and Fig. 5 is the structural representation of speed-limiting device among the embodiment three.
Embodiment one: present embodiment is made up of hook 1, decline rope 2, control cabinet, safety belt 4, pressure-reducing valve 5.The lower end of hook 1 is fixed on the upper end of decline rope 2, and pressure-reducing valve 5 hangs solid lower end at decline rope 2.Control cabinet is by brake lever 6, sleeve 7,15, housing 8, speed-limiting device are formed up and down.Speed-limiting device is made up of the quiet sheet 9, moving brake lining 10, sound brake lining frame 11,12, spring 13 explained.Quiet brake lining 9 is fixed on the quiet brake lining frame 12, and quiet brake lining frame 12 is fixed on the side in the housing 8, and moving brake lining 10 is fixed on the moving brake lining frame 11, and the lower end of moving brake lining frame 11 is set in lower end in the housing by axle 14, and sound brake lining 9,10 in opposite directions and right.The upper outside of moving brake lining frame 11 withstands on the opposite of housing 8 by a helical spring 13, and the top of moving brake lining frame 11 links to each other with the lower end of brake lever 6.Upper bush 7 is fixed near covering in housing 8 upper sheds 16 places, quiet brake lining place, and lower sleeve 15 is fixed on the going to the bottom of close quiet brake lining place housing 8 under sheds, and the top of brake lever 6 is exposed by opening 16 places of case top lid.Decline rope 2 is by in the upper bush 7, between the sound brake lining 9,10, pass in the lower sleeve 15.Safety belt 4 is made up of waistband 18, kicking strap 19, kicking strap 19 is a herringbone, the following two ends 20,21 of herringbone are connected with the middle part of waistband 18, a hook 22 is with in the upper end of herringbone, there is a loose joint that is used to lock 23 at the two ends of waistband 18, and an end of waistband 18 is hung in the hook 25 that control cabinet housing 8 goes to the bottom by rope 24.Pressure-reducing valve 5 by a cylindrical shell 26, loam cake 27, go to the bottom 28, helical spring 29 forms.Go to the bottom and 28 be fixed on the lower end of cylindrical shell 26, the lower end of helical spring 29 is fixed on the going to the bottom in the cylindrical shell 26, the upper end of helical spring 29 is fixed on the end of decline rope 2, and loam cake is enclosed within on the cylindrical shell 26, and the internal diameter of cylindrical shell 26 is greater than the external diameter of the lower sleeve 15 that is fixed on the housing 8.
