Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Examples

As shown in fig. 1 and 2, first axle group of large-scale chain drive for slag extractor, including main shaft 10 and coaxial setting at main shaft 10 on big sprocket 11, bearing 12, wheel hub 13, liquid cylinder 14 and sprocket 15, wheel hub 13 sets up at the both ends of liquid cylinder 14 and passes through bolt fixed connection with liquid cylinder 14, wheel hub 13 cover is established on main shaft 10 and is passed through spline and main shaft 10 fixed connection, be equipped with the annular engaging lug 141 of two symmetries on the lateral surface of liquid cylinder 14, each the both sides of engaging lug 141 form the slag extractor sprocket through a bolt fastening piece sprocket 15 respectively, bearing 12 is equipped with two and installs in the outside of liquid cylinder 14, big sprocket 11 passes through spline fixed mounting in one side of liquid cylinder 14 and is located the outside of bearing 12.

In the chain wheel device of traditional dragveyer, the sprocket is integral structure installation on the transmission shaft, and the shortcoming of this kind of structure is that integral structure can not dismantle, causes the maintenance trouble, need lift whole sprocket off the change when damaging, causes use cost height. The utility model discloses an penetrate into whole sprocket assembly into by main shaft 10 and the coaxial first wheel group that constitutes of 14 big sprockets 11 of liquid section of thick bamboo, bearing 12, wheel hub 13, liquid section of thick bamboo 14 and the sprocket piece 15 that set up on main shaft 10, make first wheel group become whole parts, can maintain to different spare parts like this, greatly reduced use cost.

As shown in fig. 2, the hub 13 includes a first fitting portion 131 and a second fitting portion 132, the first fitting portion 131 and the second fitting portion 132 have a cross section of "ユ", the second fitting portion 132 horizontally fits on the main shaft 10, and the horizontal portion of the first fitting portion 131 fits on the inner wall of the liquid cartridge 14. By providing the hub 13 in the shape of "ユ", the contact area of the hub 13 with the liquid cylinder 14 and the contact area of the hub 13 with the main shaft 10 are increased by the flat surface, thereby improving the stability of the connection structure.

As shown in fig. 3, a rib 133 is further disposed between the first and second

engaging portions

131 and 132 for improving the strength of the hub 13 during operation.

As shown in fig. 2 and 4, the diameter of the main shaft 10 decreases from the middle to both sides in a step shape, and sequentially includes a first shaft section 101, a second shaft section 102, a third shaft section 103, and a fourth shaft section 104 from large to small in diameter, the hub 13 is mounted in close contact with the end surface of the first shaft section 101, the bearing 12 is mounted in close contact with the end surface of the second shaft section 102, and the large sprocket 11 is mounted in close contact with the end surface of the third shaft section 103.

The main shaft 10 is arranged into a first shaft section 101, a second shaft section 102, a third shaft section 103 and a fourth shaft section 104 with variable shaft diameters, so that different parts are matched with different shaft diameters in a subsection mode, and alignment installation is facilitated, namely, the main shaft can be installed in a matched mode when the hole diameter is matched with the shaft diameter; in addition, the joints of the first shaft section 101, the second shaft section 102, the third shaft section 103 and the fourth shaft section 104 are step-shaped, so that the mounted parts can be limited, and the convenience in mounting is greatly improved.

As shown in fig. 1 and 5, a non-return wheel 16 is fixedly mounted outside the large sprocket 11 through splines, the non-return wheel 16 is mounted on the fourth shaft segment 104, non-return claws 17 matched with each other are disposed outside the teeth of the non-return wheel 16, and the non-return claws 17 are inclined toward the non-return wheel 16 and rotatably mounted on a fixing frame (not shown) through a pin. Non-return wheel 16 is used for preventing the first wheel axle group because the trouble loses the safety problem that reverses after the power and arouse, and non-return claw 17 is owing to set up for the slope, so it only needs to rely on gravity can fall back and block and realize between the teeth of a cogwheel that go into non-return wheel 16 and end, and non-return claw 17 for control such as spring reset, the utility model discloses a non-return claw 17's structure is simpler, has avoided the non-return problem that the part that resets damages the result in, and is littleer to non-return claw 17's resistance for the wear of part is littleer, and durability and reliability are stronger.
