Description

  The present invention relates to the structure of a hanging and evacuating device, and relates to a fixing device for an evacuation device that has a good appearance, does not take a place, is easy to operate and has safety.

FIG. 1 shows a kind of commonly used descent buffer evacuation device. A similar known descent buffer evacuation device mainly fixes a fixed member 81 on a main body of a building and places a descent buffer 9 there. Install. The wire rope 82 wound around the descent buffer 9 is a tool for a person to descend toward the ground. One end of the wire rope 82 is provided with a belt 83 to be used by tying a person, and the wire rope 82 main body is under the braking action of the internal mechanism of the lowering shock absorber 9, and the speed at which the relaxation wire rope 82 passes through the lowering shock absorber 9. Loosen and suspended people so that they can safely get off the ground.

However, the fixing member 81 of the known descent shock absorber is normally fixed to the ground of a building and cannot be easily moved. The suspension arm design at the tip is a foldable structure, but the fixed member 81 after folding the whole is at a height where the person can move further in the flow line where the person goes in and out. Not only does it take up space, but generally a person uses the descent shock absorber 9 together with it in another location, which is not only inconvenient to use, but also condemns the removal of the descent shock absorber at the initial time. It's easy to miss an opportunity. Further, when the above-described known fixing member 81 is used with its hanging arm extended from the wall wall of the building, the wire rope 82 of the descent buffer 9 located farther from the end of the hanging arm is stretched to increase the inside of the wall wall. After the person on the side can fasten the belt, the user must go over the wall fence and lower it to the ground after wearing the belt, which is not only complicated, but also difficult to operate.

Further, the generally known descent shock absorber 9 uses the centrifugal brake principle or has a pulley 92 around which a brake drum 91 and a set of wire ropes 82 are wound as shown in FIG. Friction contact is formed between the brake belt 94 and the brake drum by the action of the spring 93, and the pulley is decelerated by the friction damping action of the brake belt 94. However, the brake belt 94 is worn away after use, and in addition, an elastic fatigue phenomenon of the spring 93 acting on the brake belt 94 may occur, and the brake may stall and the person may fall on the ground. Further, since the wire rope 82 of the known descent buffer 9 only uses the surface friction action and the pulley 92 constituting sliding contact, when the wire rope 82 receives gravity and the rope diameter is reduced, the wire rope 82 and pulley The frictional contact action between 92 may be insufficient, causing the user to stall and crash on the ground.

    The problem to be solved is that the aesthetics are inferior, the space is occupied, the operation is more complicated and the safety is affected.

  In the present invention, a hanging arm that slides and rotates relative to the supporting and fixing frame on the main body of the supporting and fixing frame is installed, and the hanging arm is hung on the descending shock absorber. In addition, a unidirectional orientation mechanism is installed between the support fixing frame and the hanging arm, and is used to fix the direction when the hanging arm is suspended. In addition, a storage body is installed above the supporting and fixing frame, and the hanging arm, the descent buffer device and the safety belt are stored in the storage body. The descent shock absorber is mainly provided with a reduction wheel unit inside the fuselage, and a plurality of first pressing teeth are fixed to the inner walls on both sides of the fuselage. And rotating it in the axial direction relative to the wheel shaft and moving in the axial direction, the sheave meshes with the first pressing teeth by ringing a plurality of second pressing teeth on the surface of both sides of the rope groove, Configure mechanical interference. Furthermore, the main feature is to install a ridge that crosses each other on the groove wall where the two ropes face each other.

  The fixing device for an evacuation device according to the present invention has an advantage that a sheave and an inner wall on both sides of the aircraft are mechanically interfered with each other to achieve a deceleration and a descent buffer effect.

The main object of the present invention is to provide an evacuation device fixing device and its descent buffer device that has a storage effect without occupying beauty and space, and that is particularly convenient and safe to operate.

For the above-described purpose, the evacuation support fixing device of the present invention has a suspension arm that slides and rotates relative to the support fixing frame on the main body of the support fixing frame, and suspends the descent buffer device with the suspension arm. . Further, a direction changing localization mechanism is installed between the support fixing frame and the hanging arm, and the direction is fixed when the hanging arm is hung and used. In addition, a storage body is installed above the supporting and fixing frame, and the hanging arm, the descent buffer device and the safety belt are stored in the storage body.

In addition, the descent shock absorber of the present invention has a reduction wheel unit installed in the body and a plurality of guide wheels. Among them, a plurality of first pressing teeth are fixed to the inner walls on both sides of the airframe, the speed reduction wheel unit has a sheave with the wheel shaft installed inside the airframe, the sheave is rotated in the axial direction relative to the wheel shaft, and Move in the axial direction. Each guide wheel is axially installed relative to the relative shaft installation body, becomes an opening where the rope enters, limits the position of the rope, and ensures that the rope wraps around the sheave groove of the sheave.

The sheave is provided with a plurality of second pressing teeth on the surface of both sides of the sheave groove and meshed with the first pressing teeth to form a mechanical interference, and the two corresponding groove walls are mutually connected to the corresponding groove walls. Set up a mound to cross and arrange. The entire descent shock absorber reliably winds the rope around the wheel groove of the sheave by the action of the guide wheel and prevents the rope from slipping by the action of the ridge. Furthermore, when no force is applied to the rope, the sheave first forms a mechanical interference with the inner wall of one side of the fuselage, and when the rope is applied, the sheave rotates in the direction of force receiving, When the first and second pressing teeth are pressed against each other, the sheave and the wheel axle move relative to each other in the axial direction and rotate to form a machine interference with the inner wall on the other side of the fuselage. Due to the mechanical interference occurring alternately, the effect of deceleration and descent buffering is brought about.
