Abstract

The invention discloses a toothed chain. The toothed chain comprises a plurality of pin shafts arranged in parallel and rollers arranged on the two ends of each pin shaft; in the axis direction of each pin shaft, a rolling sleeve sleeving the pin shaft is arranged between the two rollers; in the moving direction of the chain, an inner plate and an outer chain plate which are connected to each pin shaft in a staggered way are arranged between any two adjacent rollers on the two sides, wherein the outer chain plate is located on the outer side of the inner chain plate; each outer chain plate located on the outermost side of the chain is integrally provided with chain teeth, and the axis of the chain teeth is perpendicular to the axis of the body of the outer chain plate and the axis of the pin shaft. The toothed chain is capable of realizing free releasing and withdrawing of a knife gillnet in a complex environment; besides, the teeth do not peel off and the chain does not drop.

Description

A kind of flute profile chain

Technical field:

The present invention relates to a kind of flute profile chain, is a kind of unwinding and winding mechanism being exclusively used in lancination net barrier disposing vehicle.

Background technique:

Present stage lancination screen cloth barrier with receive host to rely on manpower manual operations, time-consuming, effort, arrange net on a large scale receive net hardly may.Chinese patent 201320021526.9 discloses a kind of lancination net wire feeder, riveting is used to be buckled in sleeve pipe on steel wire to receipts net of arranging net, the sleeve pipe that riveting is buckled on steel wire can be jumped out frequently from V-type tooth, be wound around with V-type tooth, receipts are arranged net interruption, and destroy riveting button steel wire and lancination net, unrepairable.

Summary of the invention:

For overcoming the defect of prior art, the object of the present invention is to provide a kind of flute profile chain, this device can in complex environment folding and unfolding lancination net freely, de-tooth, does not fall chain.

Technical solution problem of the present invention adopts following technological scheme:

A kind of flute profile chain, it comprises:

Many bearing pins be arranged side by side and be located at the roller at each described bearing pin two ends, on the axial direction of bearing pin, are provided with the roll sleeve be socketed on bearing pin between two described rollers;

On the direct of travel of chain, the both sides between arbitrary neighborhood two described rollers are provided with and are connected to the inner plate be crisscross arranged on bearing pin and outer plate, and described outer plate is in the outside of inner plate;

Be in integral type on the outermost each outer plate of chain and be provided with sprocket, the axis of axes normal in outer plate body of described sprocket and the axis of bearing pin.

Be provided with each described outer plate elastic conjunction of sprocket on described bearing pin, described roller and roll sleeve and described bearing pin Spielpassung.

Compared with the prior art, beneficial effect of the present invention is embodied in:

Flute profile chain of the present invention not only can be used for transmission but also can be used for transmission, again can folding and unfolding lancination net while transmission, and structure is simple, operates steadily, and de-tooth, does not fall chain, do not damage lancination net.

The outermost two exclusive carrier bars of chain are vertically installed with sprocket, and namely when chain horizontal positioned, sprocket is straight up, and sprocket can catch on lancination net for folding and unfolding lancination net; The one section of roll sleeve be socketed on bearing pin is also provided with in the middle part of chain between two exclusive carrier bars, increase the spacing between the sprocket on two exclusive carrier bars, two rows have and guarantee to cause when catching on lancination net lancination net to come off compared with the sprocket of Large space, increase work efficiency and reliability.

Accompanying drawing illustrates:

Fig. 1 is the plan view of the present invention's one section of chain; Fig. 2 is the plan view of Fig. 1; Fig. 3 is the schematic diagram of one section of chain folding and unfolding, one section of lancination net.

Number in the figure: 1 bearing pin, 2 rollers, 3 roll sleeves, 4 inner plates, 5 outer plates, 6 sprockets, 7 lancination nets.

Below by way of embodiment, and the invention will be further described by reference to the accompanying drawings.

Embodiment:

Embodiment: composition graphs 1,2, the flute profile chain of the present embodiment, it has:

Many bearing pins 1 be arranged side by side and be located at the roller 2 at each bearing pin 1 two ends, roller and bearing pin Spielpassung, on the axial direction of bearing pin 1, be provided with the roll sleeve 3 be socketed on bearing pin between two rollers 2, roll sleeve and bearing pin are Spielpassung.

On the direct of travel of chain, the bi-side between arbitrary neighborhood two rollers, be provided with and be connected to the inner plate 4 be crisscross arranged on bearing pin and outer plate 5, outer plate is in the outside of inner plate; Namely what is called is crisscross arranged: between the first bearing pin and the second bearing pin, be connected with the inner plate 4 being in roller bi-side, is connected with the outer plate 5 be in outside inner plate between the second bearing pin and the 3rd bearing pin.

Shown in Fig. 1,2, be provided with sprocket 6 being in integral type on the outermost each outer plate of chain, the axis of axes normal in outer plate body of sprocket 6 and the axis of bearing pin, that is to say, when chain horizontal positioned, sprocket 6 is straight up, instead of level is to chain lateral expansion, in specifically arranging, be provided with each outer plate 5 elastic conjunction of sprocket on bearing pin 1, and be in the two exclusive carrier bars that contact with roll sleeve in the middle part of chain can with bearing pin Spielpassung, sprocket 6 can be set to triangular shaped, top round-corner transition.

Shown in Fig. 3, in using, chain is driven by external impetus and advances, and the sprocket be on the outermost two exclusive carrier bars of chain can firmly catch on lancination net 7, carries out the work of folding and unfolding lancination net.
