Abstract
The utility model discloses a rope wheel for a life-saving appliance. The rope wheel comprises a rope wheel body (1), wherein the rope wheel body (1) is provided with a transmission gear (2) and is coaxial to the transmission gear (2); a central hole (3) of the rope wheel body (1) is internally provided with a wear-resistant sleeve (4); and the outer side wall of the wear-resistant sleeve (4) is tightly matched with the inner wall of the central hole (3) of the rope wheel body (1). The rope wheel disclosed by the utility model is high in wear resistance and long in service life.
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, and rope drives the rotating shaft of rope sheave rope-winding wheel and rotates, and the rope sheave of prior art is generally the aluminium alloy compression casting molding structure, and rope sheave is installed on the sheave shaft through centre bore, and the wiring wheel shaft rotates.Because the escape personnel fastens rope when high building descends, rope sheave wiring wheel shaft high speed rotating, the rope sheave that aluminium alloy is processed is owing to wear no resistance, thereby makes the center bore inner wall wearing and tearing of rope sheave, and rope sheave is scrapped, and influences the service life of rope sheave.
The utility model content
The technical problem that the utility model will solve is, overcomes the defective of above prior art, provides that a kind of wearability is high, the brucker survival capsule of long service life is used 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 provided with a wear-resistant sleeve in the centre bore of said rope sheave body, the center bore inner wall tight fit of the lateral wall of said wear-resistant sleeve and rope sheave body.
After adopting above structure; A kind of brucker survival capsule of the utility model with rope sheave compared with prior art has the following advantages: be provided with a wear-resistant sleeve in the centre bore of this a kind of brucker survival capsule with rope sheave, and the center bore inner wall tight fit of the lateral wall of wear-resistant sleeve and rope sheave body; This wear-resistant sleeve plays wear-resisting effect; Thereby when making rope sheave wiring wheel shaft high speed rotating, the centre bore of rope sheave is difficult for being worn, so this brucker survival capsule is high with the rope sheave wearability, long service life.
As preferably, described wear-resistant sleeve is copper wear-resistant sleeve.
Description of drawings
Fig. 1 is the structural representation of a kind of brucker survival capsule of the utility model with rope sheave.
Fig. 2 is the front view of a kind of brucker survival capsule of the utility model with rope sheave.
Fig. 3 is that a kind of brucker survival capsule of the utility model is with the A-A sectional structure sketch map of rope sheave in Fig. 2.
As shown in the figure:
1, rope sheave body, 2, travelling gear, 3, centre bore, 4, wear-resistant sleeve.
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 and shown in Figure 3,
A kind of brucker survival capsule of the utility model 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 lines are provided with a wear-resistant sleeve 4, the centre bore 3 inwall tight fits of the lateral wall of said wear-resistant sleeve 4 and rope sheave body 1 in the centre bore 3 of said rope sheave body 1.
Described wear-resistant sleeve 4 is copper wear-resistant sleeve.Because the wearability and the hardness ratio of copper are higher, therefore this copper wear-resistant sleeve makes the anti-wear performance of rope sheave body 1 high.
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 provided with a wear-resistant sleeve (4) in the centre bore (3) of said rope sheave body (1), centre bore (3) the inwall tight fit of the lateral wall of said wear-resistant sleeve (4) and rope sheave body (1).
2. a kind of brucker survival capsule according to claim 1 is used rope sheave, it is characterized in that: described wear-resistant sleeve (4) is copper wear-resistant sleeve.
