Description

Technical Field

[0001] The utility model relates to the technical field of scraper conveyors, in particular to a reinforcing device for the telescopic tail of a scraper conveyor and a scraper conveyor. Background Art

[0002] With the increase of long-distance and extra-long-distance working faces in underground coal mines, telescopic tails have become necessary configurations on scraper conveyors, and their function is to assist in the chain tightening of scraper conveyors. Due to space limitations, the height of telescopic tails is generally designed to be relatively low, which restricts the thickness of the upper wing plates of telescopic tails to a certain extent. As a result, the upper wing plates of telescopic tails are quickly worn thin or worn off during actual use, and then the scraper jumps out of the chute at this position, causing damage to the scraper chain, affecting the operation of the scraper conveyor, and ultimately having a great impact on the production of the working face.

[0023] Embodiment 1:

[0024] As Figures 1 to 6 collectively shown, a strengthening device for the telescopic tail of a scraper conveyor includes a bottom plate 1. A scraper plate 2 is arranged on the upper surface of the bottom plate 1. The device further includes a connecting plate 3, a strengthening plate 4 and a connecting component; the bottom end of the connecting plate 3 is fixed on the upper surface of the bottom plate 1, and the strengthening plate 4 is fixed at the top end of the connecting plate 3; the strengthening plate 4 and the bottom plate 1 are arranged in parallel up and down, and the strengthening plate 4 and the bottom plate 1 respectively extend to both sides of the connecting plate 3, that is, the extending directions of the strengthening plate 4 and the bottom plate 1 are opposite; the connecting component detachably connects the strengthening device 200 to the side of the telescopic tail 100.

[0025] In the present utility model, the connecting component may include, but is not limited to, a positioning pin hole 50 and a positioning pin 51 provided on the connecting plate 3. The positioning pin 51 passes through the positioning pin hole 50 and the mounting hole on the side of the telescopic tail 100 and is locked, realizing the connection between the strengthening device and the telescopic tail. In this embodiment, two positioning pin holes 50 are provided on the connecting plate 3. One is a cylindrical pin hole, and the corresponding positioning pin is a cylindrical pin. The other is a diamond pin hole, and the corresponding positioning pin is a diamond pin. During actual connection, two mounting holes are provided on the side of the telescopic tail 100. By setting the positions of the two mounting holes and designing the one-to-one setting of the two positioning pin holes 50 and the two mounting holes, the positioning of the present utility model is realized.

[0026] In this embodiment, at least one first reinforcing rib 60 is provided between the scraper plate 2 and the bottom plate 1. Specifically, multiple first reinforcing ribs 60 are provided between the scraper plate 2 and the bottom plate 1, and all the first reinforcing ribs 60 are arranged in parallel at intervals, increasing the structural strength.

[0027] At least one second reinforcing rib 61 is provided on the connecting plate 3, and each second reinforcing rib 61 is arranged on the same side as the bottom plate 1, further enhancing the structural strength.

[0028] As Figures 1 to 6 collectively shown, when the present utility model is actually used, it is fixed to the side of the telescopic tail 100 through the cylindrical pin holes and cylindrical pins, and diamond pin holes and diamond pins, and is simultaneously connected and reinforced by high-strength bolts. After the connection is completed, the reinforcing plate 4 covers the upper wing plate of the telescopic tail 100. After the upper wing plate of the normal telescopic tail 100 is worn, the reinforcing plate 4 can continue to be used as the upper wing plate. After the reinforcing plate 4 is also worn after continued use for a period of time, the present utility model can be conveniently disassembled, and then a new one is replaced and continued to be used in matching with the original telescopic tail 100.

[0029] It can be seen that on the one hand, the present utility model extends the service life of the upper wing plate of the original telescopic tail 100, effectively preventing the scraper from skipping the chain at the telescopic tail 100; on the other hand, the replaceability of the present utility model significantly extends the overall life of the telescopic tail 100, and the replacement operation is simple, thereby effectively ensuring the smooth progress of the coal mining work.

[0030] Embodiment Two:

[0032] Because the scraper conveyor of the present utility model uses the reinforcing device 200 of Embodiment One, it effectively prevents the scraper from skipping the chain at the telescopic tail 100, effectively ensures the smooth progress of the coal mining work, and reduces the impact on the production of the working face.

[0033] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent improvements of a reinforcing device for a scraper conveyor telescopic tail and a scraper conveyor, etc., made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
