Abstract

The utility model discloses a life-saving slowly-falling equipment, which has the characters of easy use, flame retardance, good durability, non idle motion, repeated use, and self-adjusting brake resistance according to load capacity. The utility model comprises reduction gears, a brake damping disk, a lifesaving rope, and a rope drawing disc. Two reduction gears provided with conductor rope grooves are symmetrically mounted on basal discs and engaged with drive gears. The basal disc is provided with a pressing rope pulley, a guide rope pulley, and a guide rope column. The other face of the basal disc is provided with a brake rim, and a brake damp disk which is mounted with a centrifugal block via a pin is provided on a gearing shaft. An annular safe fastening strap is connected with both ends of the lifesaving rope. The life-saving rope passes through the guiding rope column, the guiding rope pulley, the reduction gear, and the pressing rope pulley, the reduction gear, the guide rope pulley, and the guide rope column in sequence. The utility model can be used for the life saving for people who are on high-rise buildings such as houses, hotels, office buildings for aliens, commercial buildings, etc.

Description

Lifesaving descent control device

Technical field:

The utility model relates to lifesaving apparatus technical field, and exactly, it is a kind of lifesaving descent control device that is used for the skyscraper life-saving.

Background technology:

In the city, along with the fast development of skyscraper, the chance of comings and goingses such as people's life in skyscraper, work, study, shopping also increases thereupon.So when dashing forward chance earthquake, fire or other disasters, people's escape method is the problem that people pay close attention to and wish to be resolved in the skyscraper always.In present actual life, except that escape way, the general escape method that just adopts of people is rope or aerial ladder substantially, and because the rope safety coefficient is low, use difficulty, the quantity of aerial ladder and rescue promptness and be difficult to again guarantee that the casualties that major disaster is caused when taking place is unavoidable.In recent years, though occurring some innovation and creation aspect the life-saving apparatus form high building tool, as Chinese patent 90226195.9,01113460.7,97106629.9,02210329.5,87214898.U etc., the disclosed portable descending lifeline of difference, descending lifeline, the transmission mechanism of fall-slowing device for rescuing from high building, various forms of descending lifelines such as centrifugal oil immersion plate friction deceleration lifesaving descent control device and gravity fluid damping descending lifeline, but because of its frame mode, using method, manufacturing cost and use cost, some factor of particularly security aspect, and never accepted extensively by society.

Summary of the invention:

The purpose of this utility model provide a kind of simple in structure, safe and reliable, reusable, non-maintaining, using method is simple, and is cheap for manufacturing cost and easily by social generally accepted skyscraper lifesaving descent control device.

The purpose of this utility model is achieved in that lifesaving descent control device comprises reduction gearing, the brake dampened disk, fabric wheel, basal disc, life line, safe ligature and receipts cheese, suspension bracket (7) and shell (6) are installed on the basal disc (9), life line (1) is coiled in to be received on the cheese (3), it is characterized in that: reduction gearing (5) symmetry that two peripheries are provided with the conductor rope groove is installed in basal disc (9) and goes up and mesh with travelling gear (10), on the center line of basal disc (9), press rope wheel (8) is equipped with in the top of two reduction gearing (5), two sheaves (4) symmetry is installed in the below of two reduction gearing (5), on the center line of basal disc (9), conductor rope post (12) is equipped with in the below of two sheaves (4), the another side of basal disc (9) is provided with brake hubs (31), brake dampened disk (23) is installed on the gearing shaft (22) with key, the array that direction is opposite centrifugal (24) is contained on the brake dampened disk (23) with bearing pin (25) removable pin, adorn brake block (21) on the outer peripheral face of centrifugal (24), the ring-type safety ligature (11) that passes from buckle (2) is connected the two ends of life line (1), and life line (1) is successively from conductor rope post (12), sheave (4), reduction gearing (5), press rope wheel (8), reduction gearing (5), sheave (4), the conductor rope post passes on (12).

The utility model has the advantages that: simple in structure, complete machine adopts the steel manufacturing, and life line adopts steel wire rope, intensity height, fire-retardant, good endurance; No-idle running, reusable; Adopt centrifugal brake damped disc structure, when load capacity is big, dampened disk rotating speed height, under action of centrifugal force, skid resistance strengthens thereupon, thereby has realized the automatic adjustment of skid resistance according to load capacity, after making that the complete machine assembling is finished, need not during use again decrease speed to be adjusted; Being used of safe ligature and buckle simplified human body bondage method, and be not only easy to use, more accelerated lifesaving speed.

Description of drawings:

Fig. 1 is an overall structure schematic diagram of the present utility model.

Fig. 2 is that the utility model decelerator A-A partly is to cutaway view.

Fig. 3 is that the utility model brake dampened disk B-B partly is to cutaway view.

The specific embodiment:

Embodiment 1:

The utility model complete machine can adopt the steel manufacturing, and life line 1 adopts galvanized steel wire rope, and safe ligature 11 adopts terylene to make, and the main material of brake block 21 can be fire-retardant asbestos.Answer for centrifugal 24 two to be one group, oppositely be provided with, to guarantee rotation direction not simultaneously, the frictional force of generation is even.

During use suspension bracket 7 is hung on the firm fixture, as caliduct, upper and lower water course, balcony guardrail etc.; To receive cheese 3 and throw to ground; Safe ligature 11 is enclosed between waist, and buckle 2 is strained to human body; The people stands on window or the balcony, hands taut the long end of life line 1, and the short end that is enclosed between waist is tightened; Health is suspended from outdoor, unclamps life line 1, under the damping action that reduction gearing 5 and centrifugal 24 and brake hubs 31 frictions are produced, the people just begins at the uniform velocity to descend, until ground.

Along with the whereabouts of life line 1 one ends, the other end of life line 1 is thrown off and rise from receiving cheese 3, and next survivor just can repeat last name survivor's action, escapes fast from skyscraper.

Embodiment 2:

According to the difference of the agent object that is used for people or thing, adjust the mounting distance between brake block 21 and the bearing pin 25, can reach the purpose that obtains differentiated friction power, distance is big more, and frictional force is big more, otherwise more little.
