Description

Technical Field

[0001] The utility model relates to the technical field of steel wire rope tube chain conveying, in particular to a transmission structure of a steel wire rope tube chain machine. Background Art

[0002] The drive structure design of existing wire rope tube chain conveyors relies on the friction between the sprocket teeth and the wire rope to drive the wire rope chain when the sprocket is driven. However, when the force on the wire rope chain is greater than the friction between the wire rope and the sprocket teeth, the wire rope chain will slip and then squeeze the wire rope chain disc. The wire rope chain disc is mainly directly injection-molded onto the wire rope and is fixed to the wire rope by the tight connection between the disc and the wire rope. If it is subjected to excessive tension, it will slip on the wire rope, causing machine failure. This limits the application range of wire rope tube chain conveyors and can only be used in situations where the tension is relatively low.

[0003] In view of the above problems, it is necessary to design a new transmission structure of a wire rope tube chain machine to overcome the above problems. Utility Model Content

[0004] The main purpose of the utility model is to provide a transmission structure of a wire rope tube chain machine, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A transmission structure of a wire rope tube chain machine includes a sprocket and a wire rope chain cooperating with the sprocket, wherein a plurality of discs meshing with the sprocket teeth are fixedly arranged on the wire rope chain in an equidistant and evenly distributed manner; the driving side of the disc in contact with the sprocket tooth groove is an umbrella-shaped arc boss, and the other side is a plane for promoting material transportation; the outer circular surface of the tooth portion of the sprocket is provided with a U-shaped groove cooperating with the wire rope, and the inner side surface of the tooth portion of the sprocket is provided with an inner arc surface cooperating with the umbrella-shaped arc boss of the disc.

[0007] Preferably, an aluminum joint for tightening the steel wire rope is embedded in the handle of the disk.

[0008] Preferably, the sprocket has at least eight sprocket teeth.

[0009] Beneficial effects

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The sprocket adopts a unique ten-tooth design and enlarges each sprocket tooth, thereby increasing the meshing length between the sprocket teeth and the wire rope, thereby increasing the friction between the sprocket teeth and the wire rope.

[0012] 2. The tooth groove of each sprocket engaging the wire rope is designed as a U-shaped groove, which increases the wire rope engaging contact surface of the wire rope chain.

[0013] 3. The side surface of each sprocket tooth is designed as a unique arc surface, which allows the side surface of the sprocket tooth to engage with multiple discs fixed on the wire rope chain. When the sprocket is driven, the sprocket will push multiple discs, and most of the thrust will be distributed among the multiple discs.

[0014] 4. The improved disc is designed with a bionic umbrella-shaped mushroom asymmetric structure. The disc is thin at the edge and thick in the middle. The thin edge reduces the contact area with the tube wall, which also reduces the friction with the tube wall. The gradually thickening in the middle ensures the strength of the disc.

[0015] 5. Improve the end face of the disk umbrella to be an arc surface, so that the disk can engage with the side face of the sprocket teeth, so that the sprocket can drive the disk.

[0016] 6. Improve the fixing method of the disc so that the disc can withstand greater driving thrust without slipping.

[0017] 7. Use hydraulic pliers to press an aluminum connector onto the wire rope at the original location where the wire rope chain disc was fixed. This connector can withstand tensile forces to the point where the wire rope deforms or even breaks without slipping or moving. Use an injection molding machine to directly mold a disc where the aluminum connector was pressed onto the wire rope chain, completely enveloping the aluminum connector. The molded disc and the pressed aluminum connector form a single unit, similarly capable of withstanding tensile forces to the point where the wire rope deforms or even breaks without slipping or moving.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-3As shown, the transmission structure of the wire rope tube chain machine of this embodiment includes a sprocket 1 and a wire rope chain 2 cooperating with the sprocket, and a plurality of discs 3 engaged with the sprocket teeth are fixedly arranged on the wire rope chain 2 in an equidistant and uniform manner; the driving side of the disc 3 in contact with the sprocket tooth groove is an umbrella-shaped arc boss 5, and the other side is a plane for promoting material transportation (the driving side is a spherical surface, which is pushed to move by the sprocket tooth groove; the other side is a plane for promoting material transportation, and the material is stored in the space enclosed by the inner wall of the material tube and the two discs); the outer circular surface of the tooth portion of the sprocket 1 is provided with a U-shaped groove 4 cooperating with the wire rope, and the inner side surface of the tooth portion of the sprocket is provided with an inner arc surface 6 cooperating with the umbrella-shaped arc boss 5 of the disc; the inner center part of the umbrella handle of the disc 3 is embedded with an aluminum joint 7 for tightening the wire rope; the number of sprocket teeth of the sprocket 1 in this embodiment is ten.

[0023] The drive structure design of the wire rope tube chain machine in this embodiment is as follows: first, the sprocket design increases the meshing length of the wire rope of the wire rope chain and the sprocket teeth, thereby increasing the friction between the sprocket teeth and the wire rope. Second, the sprocket design is improved so that the side surfaces of the sprocket teeth can also mesh with multiple discs fixed on the wire rope chain (ensuring that at least three sprocket teeth can fully mesh with the discs). When the sprocket is driven, the sprocket pushes multiple discs, and most of the thrust is distributed among the multiple discs. Third, the disc is improved to an asymmetric structure with an umbrella-shaped mushroom. This disc is thin at the edges and thick in the middle. The thin edge reduces the contact area with the tube wall and also reduces friction with the tube wall. The gradually thickening in the middle ensures the strength of the disc. Fourth, the end face of the disc is improved to a circular arc surface, so that the disc can mesh with the side surfaces of the sprocket teeth, and the sprocket can drive the disc. Fifth, the fixing method of the disc is improved so that the disc can withstand greater driving thrust without slipping. Improvements in several aspects have enabled the wire rope chain to withstand tension to the point where the wire rope deforms or even breaks without slipping or moving, greatly expanding the scope of use of the wire rope tube chain conveyor, allowing it to be used in situations where greater tension is required.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
