Abstract
The invention discloses a belt transmission rope pressing device. The belt transmission rope pressing device is characterized by being provided with a belt transmission device and a support which is used for arranging the transmission device; the belt transmission device mainly comprises shafts, belt pulleys, and a belt; in the belt transmission device, at least one belt pulley is provided with a rope groove which is used for accommodating a rope; and the rope is wound on the rope groove of the belt pulley in a through way, and is pressed tightly and fixed under the pressure of the belt, and an inlet side and an outlet side of the belt pulleys are provided with rope guide pieces which are fixed on the support. The belt transmission rope pressing device has the advantages that: the rope is pressed tightly and fixed under the pressure of the rope to ensure that strong friction between the rope and the belt pulleys and between the rope and the belt is generated, the rope can be effectively prevented from slipping and accidents can be effectively prevented.
Description
Technical field
The present invention relates to a kind of rope slow descending device, relate in particular to a kind of rope press device of cord slow-lowering device.
Background technology
In daily life or work, people often can face a danger aloft, if when not having other method to escape, need to escape by air landing device, known air landing device comprises friction speed-limited, hand brake speed-limited and hydraulic damping speed-limited, the above two shortcomings are poor reliability, the latter is relatively simple for structure, performance is also reliable, CN87216143 discloses a kind of air landing device that plays the speed limit effect with piston and cam, but cam only bears pressure, and bearing tension does not exist speed limit inhomogeneous in the landing process; ZL2003101127389 discloses respectively a kind of principle that adopts bent axle to be connected with Hydraulic Adjustable Speed formula controller with ZL2003201232361, but owing to adopt chain ladder, descent altitude is restricted; ZL2007202016917 discloses a kind of hydraulic speed-limiting formula aerial lowerator, and its structure was the rope formula, and key issue of cord slow-lowering device of crossing rope-like structure is how to guarantee that enough frictional force is arranged between rope and the rope-winding wheel.In order to increase the frictional force between rope and the rope-winding wheel, it discloses a kind of rope press device, namely be to increase upper press rope wheel and lower press rope wheel, but upper press rope wheel does not play the pressure that increases between rope and the rope-winding wheel and the effect of frictional force, although lower press rope wheel plays certain increase rope and the pressure between the rope-winding wheel and the effect of frictional force, but because lower press rope wheel is arranged on the arm and weight member is directly to be connected with arm, therefore arm must be installed in the downside of rope-winding wheel, the angle of walking around that rope is put to the pressure rope from the force side only has the angle of half circumference, therefore, the pressure rope effect that plays not is fine; Herein, rope is referred to as to press the rope cornerite from the force side to the angle of walking around of pressing the rope point.
Summary of the invention
Press the rope cornerite less in order to overcome now the disclosed rope press device of crossing the cord slow-lowering device of rope-like structure, press the bad problem of rope effect, the present invention proposes a kind of belt drive type pressure rope device, it is to utilize belt drive unit, be provided for holding therein the grooving of working rope at least one belt pulley, rope is wrapped on the grooving of belt pulley and is fixed under the pressure of belt, make and all produce powerful frictional force between rope and belt pulley, rope and the belt, prevent that effectively rope from skidding, effectively prevent accident.
The technical scheme that technical solution problem of the present invention adopts is, a kind of belt drive type pressure rope device that the present invention proposes, it is characterized in that, a belt drive unit is set and the bearing of transmission device be used for to be installed, described belt drive unit mainly comprises axle, belt pulley, belt, described belt drive unit has at least a belt pulley to be provided be used to the grooving that holds rope, and rope is wrapped on the grooving of belt pulley with crossing the rope formula and is fixed under the pressure of belt and entrance side and the outlet side of described belt pulley are provided with the conductor rope spare that is fixed on the bearing.
Preferred version of the present invention: institute's conductor rope spare is by the annular element that is opening after the wire bending.
The invention has the beneficial effects as follows, the present invention proposes a kind of belt drive type pressure rope device, it is to utilize belt drive unit, rope is wrapped on the grooving of belt pulley and under the pressure of belt, is fixed, make and all produce powerful frictional force between rope and belt pulley, rope and the belt, can prevent effectively that rope from skidding, and effectively prevents accident.
