Detailed description of the invention

As Fig. 1, shown in Fig. 2, a kind of Emergency Ladder of the utility model, comprise upper unit 1, lower device 2 and rope ladder 3, described upper unit 1 comprises A-frame 11, support bar 12 and upper cylinder 13, described upper cylinder 13 is hollow cylinder, two end faces are the circular end face that diameter is greater than drum diameter, the center of described upper cylinder 13 is fixed with the first rotating shaft 14, two outer ends of described first rotating shaft 14 are connected with upper sleeve pipe 15 by bearing, described two upper sleeve pipes 15 are individually fixed in one end of two support bars 12, the other end of described support bar 12 is fixedly connected with the drift angle of A-frame 11, the drift angle opposite side of A-frame 11 is fixed on roof,

Described lower device 2 comprises bracing frame 21, bottom roll 22 and check mechanism 23, the cylindrical shell size of bottom roll 22 is identical with upper cylinder 13, and be positioned at immediately below cylinder 13, the barrel of bottom roll 22 is symmetrically arranged with two circle blocks 23, often circle block circularizes equidistantly uniform around the central axis of bottom roll 22, the center of described bottom roll 22 is fixed with the second rotating shaft 24, two outer ends of described second rotating shaft 24 are connected with setting of casing 25 by bearing, described setting of casing 25 is fixed on bracing frame 21, one end of described second rotating shaft 24 is connected to drive unit, the other end is connected to can the check mechanism 26 of locking bottom roll 22, support frame as described above 21 is triangle support frame, be fixed on ground,

Described rope ladder 3 comprises steel wire 31 and the Duo Gen body of rod 32, length is slightly less than the barrel length of cylinder 13 and bottom roll 22, the described body of rod 32 two ends symmetry has through hole 33, the body of rod 32 is fixed on steel wire 31 through through hole 33 by capable for U card article, thus multiple body of rod 32 is run through, equidistant arrangement between the body of rod 32 and the body of rod 32, described steel wire 31 walks around cylinder 13 and bottom roll 22, end to end formation circulus, the described body of rod 32 is installed between block 23.

The barrel of described upper cylinder 13 can be arranged block group mutually isostructural with the block 23 on bottom roll 22.

Described rope ladder 3 is movably set with safety net 34, by safety hook 35, safety net 34 is hung on the body of rod 32.

Concrete mounting method:

Two upper sleeve pipes 15 are welded on two support bars 12 respectively, the two ends of the first rotating shaft 14 are penetrated in upper sleeve pipe 15, again support bar 12 is fixed on A-frame 11, upper cylinder 13 is stretched out after outside body of wall and A-frame 11 is fixed on roof, complete the assembling of upper unit 1; Two setting of casings 22 are welded to two fulcrum places of bracing frame 21, the two ends of the second rotating shaft 24 are penetrated in setting of casing 25, in one end of the second rotating shaft 24, check mechanism 26 is installed, then bracing frame 21 is fixed on ground, completes the installation of lower device 2; Rope ladder 3 is walked around upper cylinder 13 and bottom roll 22, owing to being fixed with along the equally distributed two circle blocks 23 of bottom roll 22 central axis on bottom roll 22 barrel, gap is left between block 23 and block 23, the spacing in its gap is slightly larger than the diameter of the body of rod 32, the two ends of the body of rod 32 are stuck in respectively in the gap of two circle blocks 23, it is made to be horizontally set on bottom roll 22 sidewall, again by two of rope ladder 3 steel wires 31 mutual connection end to end, complete the installation of rope ladder 3, so just can realize bottom roll 22 and drive the body of rod 32 to move or the body of rod 32 is stirred bottom roll 22 and rotated; Wherein, absolute upright is wanted in the position of upper cylinder 13 and bottom roll 22, guarantees rope ladder 3 vertically downward, equipment should be arranged in the middle of each unit during installation, and two families, left and right are used simultaneously.

In addition, attractive in appearance in order to not affect building, can upper cylinder 22 being made into movable, when not using, upper cylinder 22 and rope ladder 3 being positioned on ground, on roof, hoist engine is set, hoist engine, with wire rope and hook, when needs application apparatus, is opened by hoist engine, put down wire rope and hook, then upper cylinder 22 and rope ladder 3 are hooked to roof, upper cylinder is fixed on A-frame 11, the assembling of finishing device.

In addition, in the bottom of A-frame 11 and bracing frame 21, slideway and roller can be installed, for adjusting the position of whole device on ground and roof, when position breaking out of fire away from device, manually device can be moved to fire scene by slideway entirety, facilitate indicator of trapped personnel to withdraw.

Concrete using method:

When there is the condition of a fire, user first should fasten safety rope, and be hung on the body of rod 32 by the safety hook 35 on safety rope, both hands firmly grasp the body of rod 32, and both feet slam the body of rod 32; When there is power supply unit on ground, ground salvor connects drive unit, the rotary speed of bottom roll 22 is controlled by drive unit, adjust the rotary speed of bottom roll 22 according to the concrete condition of a fire and user's situation, guarantee that indicator of trapped personnel is within the shortest time, transfer to ground with safest speed, simultaneously, fire fighter can utilize this Emergency Ladder to be sent to fire place, need not use ground lifting machine, time saving and energy saving; When ground does not have power supply unit, user stands on rope ladder 3, rope ladder 3 glides automatically due to the gravity of user, now need salvor to arrive in lower device 2 place in the very first time and control check mechanism 26, the clamp system of check mechanism 26 is installed on one end of second driving shaft 24, regulate clamp system to the clamping degree of second driving shaft 24 by the manual rocker in operate brake 26, thus the rotary speed of adjustment bottom roll 22; When indicator of trapped personnel be the old,weak,sick and disabled etc. cannot use the personnel of Emergency Ladder voluntarily time, net 34 is completely hung on the body of rod 32 by safety hook 35, indicator of trapped personnel is placed in safety net 34, then safety net 34 is transported to ground, thus realize the relief to the old,weak,sick and disabled.

When not having the condition of a fire at ordinary times, this device may be used for conveying articles, especially some is not had to the building of elevator, and this device can replace elevator as small-size carrying equipment use.

By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from the utility model aim.
