Abstract

The utility model discloses a cylinder outer sleeve for hoisting operation, which is double-layered. Left edges of an inner layer and an outer layer are connected through a weft, right edges of the inner layer and the outer layer are connected through a weft, and other parts of the inner layer and the outer layer are independent of each other. The cylinder outer sleeve is more wear-resistant, endurable and beautiful, increases safety performance, effectively protects load carrying cores from damage by direct friction, and prolongs service life.

Description

The double-layered cylinder overcoat of using in a kind of lifting operation

Technical field

The utility model relates to a kind of in the lifting operation process, can protect the cylinder sleeve of load bearing core.

Background technology

Present known polyester thread cylinder hardness all is alternately to weave the individual layer cylinder hardness (as shown in Figure 1) that forms by four groups of warps, parallel, lock seaming line on seam loop, individual layer cylinder hardness 1 is in hoisting process, overcoat with direct friction can be taken place by lifting object, overcoat can be by friction repeatedly in stressed process, the surface of overcoat can fluff even organize line to rupture in friction process, causes suspender belt and can not use because of the breakage of overcoat, spilling of load bearing core.On simultaneously a lot of lifting objects corner angle and sharp edges are arranged all; the individual layer overcoat is easy to be damaged by corner angle and cutting edge of a knife or a sword mouth incised wound in hoisting process; overcoat hurt and breakage after can not actv. the load bearing core of protection overcoat the inside; cause load bearing core to spill and with rubbed by lifting object; if load bearing core can be because the very fast long-term exposure of fluffing, fracture and load bearing core in the sun can be by ultraviolet radiation under the protection that does not have sheath; with low operating cycles, brought hidden danger to safe operation.

The utility model content

For solving the problem that prior art exists, the utility model provides a kind of safety firm double-layered cylinder overcoat.

The utility model is achieved in that

The cylinder sleeve of using in a kind of lifting operation, described cylinder sleeve is double-deck, the left side of internal layer and the outer field left side link together by a parallel, and the right of internal layer and outer field the right link together by a parallel, and internal layer and outer field other positions are separate.

Optionally, described cylinder sleeve employing high-strength polyester line braiding.

Further, the outer 3300D of employing of described cylinder sleeve high-strength polyester line weaves.

Further again, described cylinder sleeve internal layer adopts the braiding of 1670D high-strength polyester line.

Further again, described cylinder sleeve is received the limit and is adopted the braiding of 1100D high-strength polyester line.

Further again, the braiding of 550D high-strength polyester line is adopted in described cylinder sleeve lock seaming.

The cylinder sleeve that the utility model provides than the cylinder sleeve of prior art antifriction, durable, attractive in appearance more, has increased operating cycles; And lifting during article when ground floor overcoat during by the breakage of lifting object incised wound, second layer protective coat can protect load bearing core is not timely and effectively damaged it by direct friction, simultaneously avoided load bearing core to be subjected to ultraviolet radiation again, improved the safety performance of cylinder sleeve, increase simultaneously the bearing capacity of cylinder sleeve again, prolonged service life; Owing to be double-decker, more abundant, can not corrugated during color on overflow dyeing machine by the air cylinder pressure, after passing through the baking of baking box, color relation is well-proportioned to be distributed in the organized layer, has improved the qualification rate of overcoat like this.

Description of drawings

Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, does not constitute to improper qualification of the present utility model, in the accompanying drawings:

Fig. 1 is the structural representation of individual layer cylinder sleeve of the prior art;

The structural representation of the double-layered cylinder overcoat that Fig. 2 provides for the utility model.

The specific embodiment

Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to qualification of the present utility model.

As shown in Figure 2, the cylinder sleeve that present embodiment provides is by inside and outside two-layer the composition, the left side of internal layer 2 links together by a parallel with the left side of skin 3, and the right of internal layer 2 links together by a parallel with the right of skin 3, and internal layer and outer field other positions are separate.

In the present embodiment, cylinder sleeve outer 2 adopts the braiding of 3300D high-strength polyester line, cylinder sleeve internal layer 3 adopts the braiding of 1670D high-strength polyester line, and cylinder sleeve is received limit 4 and adopted the braiding of 1100D high-strength polyester line, and the braiding of 550D high-strength polyester line is adopted in cylinder sleeve lock seaming 5.

More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on the specific embodiment and field of application, all can change, in sum, this description should not be construed as restriction of the present utility model.
