Description
Technical field:
The utility model relates to a kind of eminence rope and falls escape apparatus, belongs to a kind of rope falling unit.
Background technology:
People are being engaged in mountain-climbing, when rock-climbing waits motion, perhaps when skyscraper faces a danger, all need to use escape device, and mainly be the rope falling unit, common eminence rope falls escape apparatus mainly by clamping plate at present, top sheave, contact roller, bearing pin, top sheave department cover nut, the top sheave bolt, contact roller department cover nut, the contact roller bolt, module, the degree of tightness handle, tension spring and hanging ring are formed, bearing pin, the top sheave bolt, the contact roller bolt is contained on the clamping plate, top sheave is contained on the top sheave bolt, contact roller is contained on the contact roller bolt, the degree of tightness handle connects contact roller, tension spring is contained on the contact roller bolt and connects contact roller, contact roller is single cam-like, its cam direction is pointed to top sheave, during use, rope is contained in escape apparatus, the rope upper end is connected a fixture, hanging ring connects user's health, do not carry out under the free state of any operation the user, owing to the effect of tension spring makes the cam of contact roller press to top sheave, make rope compacted, user's health is fixed on the rope; As user during to the degree of tightness handle application of force, just can overcome the elastic force of tension spring and the cam of contact roller is unclamped, rope is pressurized and make user's health glide no longer; The user also can be by changing the speed of the dynamics of the degree of tightness handle application of force being controlled downslide.But, when above-mentioned escape apparatus is operated, because user's qualification, psychological quality difference, the user that some are trained, are nervous tends to be regardless of situation and holds on to the degree of tightness handle it is closed, and makes the cam of contact roller unclamp for a long time, cause maloperation, make downslide out of control, produce at a high speed and glide, make the user injured.
Summary of the invention:
The purpose of this utility model provides a kind of eminence rope and falls escape apparatus, and it can overcome the deficiencies in the prior art.
The utility model is achieved in that it is mainly overlapped nut, contact roller bolt, module, degree of tightness handle, tension spring and hanging ring and formed by clamping plate, top sheave, contact roller, bearing pin, top sheave department cover nut, top sheave bolt, contact roller department, it is characterized in that having lower sheave, lower sheave department cover nut and lower sheave bolt, this lower sheave bolt is contained on the clamping plate and is in the below of contact roller, lower sheave is contained on the lower sheave bolt, contact roller is the double cam structure, its overhead cam direction is pointed to top sheave, and it is cam direction sensing lower sheave down.
The utility model under free state or the user hold on under the situation of degree of tightness handle, can both allow user's health be fixed on the rope, effectively avoid maloperation, compared with prior art, have safe and reliable, easy to operate, advantages of simple structure and simple.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
The specific embodiment:
As shown in Figure 1, the utility model is mainly by clamping plate 1, top sheave 3, contact roller 4, bearing pin 5, top sheave department cover nut 6, top sheave bolt 7, contact roller department cover nut 8, contact roller bolt 9, module 10, degree of tightness handle 11, tension spring 13 and hanging ring 14 are formed, it is characterized in that having lower sheave 15, lower sheave department cover nut 16 and lower sheave bolt 17, this lower sheave bolt 17 is contained on the clamping plate 1 and is in the below of contact roller 4, lower sheave 15 is contained on the lower sheave bolt 17, contact roller 4 is the double cam structure, its overhead cam 4A direction is pointed to top sheave 3, and it is cam 4B direction sensing lower sheave 15 down.
During use, as shown in Figure 2, rope 2 is contained on the utility model, rope 2 upper ends are connected a fixture, hanging ring 14 connects user's healths, does not carry out under the free state of any operation the user, owing to the effect of tension spring 13 makes the overhead cam 4A of contact roller 4 press to top sheave 3, make rope 2 compacted, user's health is fixed on the rope 2; When the user applies certain power to degree of tightness handle 11, just can overcome the elastic force of tension spring 13 and the overhead cam 4A of contact roller 4 is unclamped, rope 2 is pressurized and make user's health glide no longer; When the user held on to degree of tightness handle 11 with all strength, the following cam 4B of contact roller 4 was pressed to lower sheave 15, makes rope 2 compacted, and user's health can be fixed on the rope 2 equally; The user also can be by changing the speed of the dynamics of degree of tightness handle 11 application of forces being controlled downslide.
