detailed description

Below, in conjunction with accompanying drawing and specific embodiment, the utility model is described further:

As shown in Figures 1, 2 and 3, it is an installation structure of a single-bucket hoist hopper of the present invention, which includes a hopper 10, a chain 20 and a fixing assembly 30, and the chain 20 is used to drive the hopper 10 to reciprocate up and down, fix Assembly 30 comprises upper fixture 31 and lower fixture 32, and upper fixture 31 is positioned at the top of chain 20, and lower fixture 32 is positioned at the below of chain 20, and upper fixture 31 and lower fixture 32 form a clamping mechanism, and chain 20 Clamped between the upper fixing part 31 and the lower fixing part 32, and the upper fixing part 31 and the lower fixing part 32 are locked by bolts, and the length direction of the upper fixing part 31 and the lower fixing part 32 is consistent with the extending direction of the chain 20; The upper fixing part 31 is also provided with a protruding tooth 311, and the protruding tooth 311 is inserted into the chain link recess of the chain 20. A shaft sleeve 33 is also fixed on the fixing assembly 30, and a shaft head 12 is fixed on the side of the hopper 10. The head 12 is passed through the shaft sleeve 33 , and the shaft head 12 is pivotally matched with the shaft sleeve 33 , so that the hopper 10 is rotatably matched with the fixing assembly 30 .

In the utility model, since the upper fixing part 31 and the lower fixing part 32 are used to clamp the chain 20, the degree of freedom of the fixing assembly 30 moving up and down relative to the chain 20 is limited. The plug-in fit relationship of the concave position in the joint limits the freedom of the fixed component 30 to move longitudinally and laterally relative to the chain 20; compared with the existing method of connecting the chain with a shaft pin, the utility model utilizes the upper fixing part 31 and the lower The fixing member 32 clamps the chain 20 to install the hopper 10 on the chain 20, which increases the strength of the joint between the hopper 10 and the chain 20, and improves the safety of the single-bucket elevator.

In the present utility model, the axle sleeve 33 is fixed on the upper fixing member 31 by bolts, of course, the axle sleeve 33 can also be fixed on the lower fixing member 32 by bolts.

In order not to affect the inner space of the hopper 10, a fixed frame 11 is fixed on the bottom surface of the hopper 10, and the shaft head 12 is fixed on the fixed frame 11 by bolts.

In the above solution, protruding teeth 311 are provided on the upper fixing member 31. In order to further increase the connection strength, a plurality of protruding teeth 311 may be provided on the upper fixing member 31, and the plurality of protruding teeth 311 extend along the extending direction of the chain 20, etc. arrangement of spacing; it should be noted that the above-mentioned protruding teeth 311 can be arranged not only on the upper fixing member 31, but also on the lower fixing member 32, and of course also on both the upper fixing member 31 and the lower fixing member 32. Convex teeth 311.

For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and ideas described above, and all these changes and deformations should fall within the protection scope of the claims of the present utility model.
