Abstract
The utility model discloses a rope wheel for a life preserver. The rope wheel comprises a rope wheel body (1), wherein the rope wheel body (1) is provided with and coaxial with a transmission gear (2); and two inner side walls of a wiring groove (3) of the rope wheel body (1) are evenly provided with multiple bumps (4) distributed at intervals along the peripheral direction. According to the rope wheel for the life preserver, the frictional force between the rope and the rope wheel is large, and the descent speed of the rope and the rotating speed of the rope wheel are synchronous.
Description
Technical field
The utility model relates to the high-rise building life saving equipment technical field, specifically is that a kind of brucker survival capsule is used rope sheave.
Background technology
At present, the awareness of safety that the taking place frequently of fire in high buildings makes people is in continuous enhancing, and some indispensable lifesaving appliances have also got into every family, and the most frequently used lifesaving appliance is such as fire extinguisher, fire sand box, life car, cable type brucker survival capsule etc.The cable type brucker survival capsule of prior art; Its structure generally comprises rope and the housing that is fixedly connected with body of wall, is provided with rope sheave and decelerator in the described housing, is wound with rope on the described rope sheave; And rope sheave is provided with travelling gear, the gear of said rope sheave and the engagement of the reduction gearing of decelerator; When the high building breaking out of fire was escaped, the people was enclosed within on the rope, landed downwards from window then, because the decelerating effect of decelerator, the escape personnel is when descending, and the speed of rope keeps within the specific limits, can tumble injury when the people lands to cause.The brucker survival capsule of this structure is when rope descends; Rope drives rope sheave and rotates; Because rope sheave speed limit under the effect of decelerator is rotated, the frictional force between rope and the rope sheave is little, and rope is with respect to slip is arranged between the rope sheave; So just be easy to cause the rotating speed of rope decrease speed and rope sheave asynchronous, cause jumping stranger person when landing because of the excessive tumble injury of decrease speed.
The utility model content
The technical problem that the utility model will solve is, overcomes the defective of above prior art, provides that frictional force between a kind of rope and the rope sheave is big, the brucker survival capsule of the synchronization of rope decrease speed and rope sheave uses rope sheave.
The technical solution of the utility model is; Provide a kind of brucker survival capsule with following structure to use rope sheave: it comprises the rope sheave body; Described rope sheave body is provided with travelling gear; Described rope sheave body and travelling gear coaxial line are equipped with a plurality of along its circumferencial direction convexity spaced apart on two madial walls of the wiring groove of said rope sheave body.
After adopting above structure; The utility model brucker survival capsule with rope sheave compared with prior art; Have the following advantages: be equipped with a plurality ofly along its circumferencial direction convexity spaced apart on two madial walls of this brucker survival capsule with the wiring groove of the rope sheave body of rope sheave, this convexity plays the frictional force that increases rope and rope sheave, when rope drives the rope sheave rotation; Frictional force is big between rope and rope sheave; Make rope with respect to not sliding between the rope sheave, thereby make the synchronization of rope decrease speed and rope sheave, so jump stranger person and land Shi Buhui tumble injury because decrease speed is excessive.
As preferably, described a plurality of convexities are arc convex, and the spacing of every adjacent two convexities equates.This arc convex makes the frictional force between the wiring groove of rope and rope sheave body more even, and the speed that rope descends is more steady, and security is higher.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5,
The utility model brucker survival capsule is used rope sheave; It comprises rope sheave body 1; Described rope sheave body 1 is provided with travelling gear 2, and described rope sheave body 1 and travelling gear 2 coaxial lines are equipped with a plurality of along its circumferencial direction convexity 4 spaced apart on two madial walls of the wiring groove 3 of said rope sheave body 1.This convexity 4 plays the frictional force that increases rope and rope sheave body; When rope drives the rotation of rope sheave body; Frictional force is big between rope and rope sheave body; Make rope with respect to not sliding between the rope sheave body, thereby make the synchronization of rope decrease speed and rope sheave, so jump stranger person and land Shi Buhui tumble injury because decrease speed is excessive.
Described a plurality of protruding 4 are arc convex, and the spacing of every adjacent two convexities 4 equates.
Claims (2)
1. a brucker survival capsule is used rope sheave; It comprises rope sheave body (1); Described rope sheave body (1) is provided with travelling gear (2); Described rope sheave body (1) and travelling gear (2) coaxial line is characterized in that: be equipped with a plurality of along its circumferencial direction convexity spaced apart (4) on two madial walls of the wiring groove (3) of said rope sheave body (1).
2. brucker survival capsule according to claim 1 is used rope sheave, it is characterized in that: described a plurality of convexities (4) are arc convex, and the spacing of every adjacent two convexities (4) equates.
