Description

High building disaster escape apparatus

Technical field

The utility model relates to a kind of high building disaster escape apparatus.

Technical background

The passage of high-rise is narrow, in case the big disaster of breaking out of fire or the like, the personnel of the inside are difficult to withdraw fast.Very feasible escape truck when the window in room is withdrawn separately, but must just can land safely by lifting tool when withdrawing by window.Aerial ladder is a kind of good high-altitude lifting tool, but when disaster took place, aerial ladder was often not enough, can't satisfy the requirement of a large amount of personnel's centralized evacuations.

Summary of the invention

The purpose of this utility model provides a kind of high building disaster escape apparatus simple in structure, easy to use, can be used as resident's essential product commonly used, uses in high building generation disaster, to remedy the deficiency of aerial ladder under the state of emergency.

For achieving the above object, the utility model adopts following technical scheme:

High building disaster escape apparatus described in the utility model comprises the lanyard frame, be connected the rope on the lanyard frame, it is characterized in that: on rope, be connected with the rope distributor, this rope distributor comprises shell, be installed in main shaft in the shell by bearing, rope passes the upper end of shell, be wrapped on the main shaft, the hinge and the camshaft that are parallel to main shaft also are installed in the enclosure, be hinged with brake block and following brake block on the hinge, cam bit is installed on the camshaft, main shaft and cam bit are between last brake block and following brake block, the handle that extends to housing exterior is installed on the cam bit, is connected with return spring between last brake block and the following brake block.

Be fixedly connected with safety belt on the shell.

Be provided with guide wheel in the upper end of shell, the both sides of rope, on riser, riser is fixedly connected on the upper end of shell to this guide wheel by the rotating shaft mounted in pairs.

Adopt after the technique scheme, this high building disaster escape apparatus is simple in structure, easy to use, can be used as resident's essential product commonly used, uses in high building generation disaster, to remedy the deficiency of aerial ladder under the state of emergency.

Description of drawings

Fig. 1 is the structural representation of an embodiment of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1.

The specific embodiment

As shown in drawings, high building disaster escape apparatus described in the utility model comprises lanyard frame 1, is connected the rope 2 on the lanyard frame 1, and fixed mount 1 is the channel-section steel shape, and the one side can also fixing device for installing.As shown in Figure 1, this fixture is a screw rod that has rotation hand wheel, and this screw rod interts on the sidewall of fixed mount 1, and a top board is installed in the inner of screw rod.Be connected with the rope distributor in the lower end of rope 2, this rope distributor comprises shell 3, is installed in main shaft 4 in the shell 3 by bearing, rope 2 pass shell 3 the upper end, be wrapped on the main shaft 4, in order to prevent that rope 2 from crossing the border, can also on main shaft 4, fixedly mount two side shields 18, rope 2 is wrapped between two side shields 18.The hinge 5 and the camshaft 6 that are parallel to main shaft 4 also are installed in shell 3, be hinged with brake block 51 and following brake block 52 on the hinge 5, cam bit 61 is installed on the camshaft 6, main shaft 4 and cam bit 61 are between last brake block 51 and following

brake block

52,52 one-tenth tong-likes of last brake block 51 and following brake block are clipped in the outside of main shaft 4 and cam bit 61, in order to increase contact area, to improve frictional force, can also be designed to circular-arcly with going up brake block 51 and position that following brake block 52 contacts with main shaft 4, and stick friction plate in the inboard.The handle 8 that extends to shell 3 outsides is installed on the cam bit 61, pulls handle 8 and can drive cam bit 61 rotations.Be connected with return spring 7 between last brake block 51 and the following brake block 52.This return spring 7 can be the extension spring that is connected brake block 51 and following brake block 52 ends as shown in Figure 1, also can be mounted in the torsion spring on the hinge 5, and its effect is that brake block 51 and following brake block 52 are drawn close, and keeps the state of clamping spindle 4.

In addition, use for convenience, on shell 3, be fixedly connected with safety belt 9, safety belt 9 can be enclosed within on the person in the time of use.

In order to prevent the shell wall friction of rope 2 and shell 3, influence the folding and unfolding of rope 2, be provided with guide wheel 10 in the upper end of shell 3, the both sides of rope 2, this guide wheel 10 is for having the pulley of grooving, on riser 11, riser 11 is fixedly connected on the upper end of shell 3 by the rotating shaft mounted in pairs.Rope 2 enters shell 3 by the centre of two guide wheels 10, has avoided directly and the shell wall friction of shell 3.Help reducing the resistance of rope folding and unfolding, increase the service life.

This high building disaster escape apparatus is simple in structure, and production cost is low, can be used as resident's essential product commonly used, uses in high building generation disaster.During use, fixed mount 1 is installed on the fixtures such as windowsill or railing, and is locked by rotation hand wheel.The rope distributor is suspended in outdoor, pin is stepped on safety belt 9, perhaps directly safety belt 9 is enclosed within on the person.At this moment, owing to have last brake block 51 and following brake block 52 to clamp main shaft 4, it can not be rotated, rope 2 can't put down.Upwards or pull handle 8 downwards, cam bit 61 rotations also will be gone up brake block 51 and following brake block 52 jack-up, unclamp main shaft 4, and under the gravity effect, main shaft 4 rotates, and rope puts down, thereby rope distributor and people are put into ground.In the decline process, if want to stop or underspeed, as long as handle is returned to the centre position.
