Description

Technical Field

[0001] The invention relates to the technical field of mining transfer machines, in particular to a transfer machine convex groove. Background Art

[0002] The transfer machine is an important transportation equipment for the fully mechanized working face in underground coal mines. Its convex groove is used as a supporting component of the chain transmission to lift the coal output by the scraper at a lower position to the belt conveyor at a higher position. The middle plate and the bottom plate are the key components of the convex groove. Since the convex groove is at the turning point between the slope and the straight line transportation, during the operation of the scraper middle chain, the middle chain slides close to the convex groove middle plate, causing the convex groove middle plate to bear the impact of coal, chain friction and alternating load for a long time, which is prone to wear, deformation and even breakage.

[0003] In the prior art, the middle plate of the convex groove of the transfer machine is mostly an integral welded structure. When the middle plate of the convex groove is to be repaired or replaced, the machine needs to be shut down and the entire groove body needs to be dismantled, which is time-consuming and labor-intensive. In addition, the entire trough needs to be replaced after local wear, which is costly. Therefore, there is an urgent need for a convex groove structure that can be quickly disassembled and replaced and supports local replacement and repair.

[0004] The above contents are only used to assist in understanding the technical solution of the present invention, and do not constitute an admission that the above contents are the closest prior art. Summary of the invention

[0005] The purpose of the present invention is to provide a transfer machine convex groove to solve the problem raised in the above background technology that each time the middle plate of the convex groove is repaired and replaced, the entire groove body needs to be repaired and replaced, which results in high cost and low maintenance efficiency.

[0046] It should be noted that: when a plug plate 211 at a certain position in the transition component 21 is damaged and needs to be replaced, the fastening component 22 corresponding to the plug plate 211 at the damaged position is pulled out, and then the damaged plug plate 211 is pulled out through the through groove 14, and the newly replaced plug plate 211 is inserted into the position of the original damaged plug plate 211 through the through groove 14, and then the replaced plug plate 211 is fastened by the fastening component 22, so that when the locally worn middle plate is replaced, there is no need to replace the entire slot body, thereby reducing the replacement cost of the middle plate.

[0047] Embodiment 2

[0048] like Figure 1-5 As shown, the components identical or corresponding to those in the above embodiment are marked with the corresponding reference numerals in the above embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0049] The convex groove unit 1 also includes:

[0050] A front middle plate 12, fixedly connected to the front inner sides of the convex groove body 11;

[0051] The rear middle plate 13 is fixedly connected to the inner two sides of the convex groove body 11 at the rear, and a gap is provided between the front middle plate 12 and the rear middle plate 13 for accommodating the transition assembly 21 .

[0052] Furthermore, the front middle plate 12 is located on one side of the transition assembly 21 and is provided with a first limiting rod 121 for limiting one end of the transition assembly 21;

[0053] The rear middle plate 13 is provided with a first limiting groove 131 on one side of the transition component 21 for limiting the other end of the transition component 21 .

[0054] It should be noted that: by inserting the second limiting groove 212 on the side of the first plug rod 222 into the outside of the first limiting rod 121, and then gradually extending the subsequent plug rods 222 from the first plug rod 222 along the trajectory of the through groove 14 to the rear middle plate 13, and the second limiting rod 213 on the side of the last plug rod 222 is inserted into the first limiting groove 131, the splicing work of multiple plug rods 222 is completed, and each plug rod 222 can remain continuous and tight, ensuring that the scraper chain can remain smooth during the material conveying process.

[0055] Embodiment 3

[0056] like Figure 1-4 As shown, the components identical or corresponding to those in the above embodiment are marked with the corresponding reference numerals in the above embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0057] The transition component 21 comprises:

[0058] The inserting plates 211 are provided in a plurality of groups in sequence and continuously along the extending direction of the through slot 14 and between the front middle plate 12 and the rear middle plate 13;

[0059] The limiting hole 214 is provided at the upper end of the plug plate 211 and corresponds to the fastening assembly 22 , and is used for cooperating with the fastening assembly 22 to position the plug plate 211 .

[0060] Furthermore, a second limiting groove 212 is formed on one side of the plug board 211 , and a second limiting rod 213 is fixedly connected to the other side thereof and matches the second limiting groove 212 on one side of the previous plug board 211 , so as to limit the adjacent plug boards 211 .

[0061] Furthermore, the second limiting groove 212 and the second limiting rod 213 are both configured to be T-shaped, so as to lock the distance between two adjacent plug boards 211 .

[0062] It should be noted that after the two adjacent plug rods 222 are spliced, the T-shaped second limiting rod 213 on one side of one of the plug rods 222 cooperates with the T-shaped second limiting groove 212 on one side of an adjacent plug plate 211, so that the two adjacent plug rods 222 will not separate from each other during the working process, ensuring that the plug rods 222 cooperate closely with each other and have high reliability.

[0063] Embodiment 4

[0064] like Figure 2-3 , Figure 6-7 As shown, the components identical or corresponding to those in the above embodiment are marked with the corresponding reference numerals in the above embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0065] The fastening assembly 22 comprises:

[0066] A plurality of fixing blocks 221 are provided along the extending direction of the convex groove body 11 and above the rear middle plate 13 and correspond to the plug plates 211 one by one. The fixing blocks 221 are fixedly connected to the outer side of the convex groove body 11, and a first clamping hole 2211 is penetrated inside the fixing blocks 221;

[0067] The inserting rod 222 extends through the first locking hole 2211 to the inside of the second locking hole 2231 and is used to position the inserting plate 211 .

[0068] Furthermore, the insertion rods 222 are provided in multiple groups and correspond one by one to the limiting holes 214;

[0069] The upper end of the insertion rod 222 is fixedly connected to a limiting block 2221 above the fixing block 221 for limiting the insertion rod 222 .

[0070] Furthermore, the fastening assembly 22 further includes:

[0071] A fixing rod 223, fixedly connected to the side of the convex groove body 11 and located below the plug board 211;

[0072] A plurality of second locking holes 2231 are provided at the upper end of the fixing rod 223 . The second locking holes 2231 correspond to the insertion rods 222 one by one and are used to limit the lower end of the insertion rods 222 .

[0073] Wherein, the through groove 14 is set to be an arc with the same arc as the convex groove body 11;

[0074] The plurality of inserting plates 211 are sequentially connected to form an arc shape having the same arc as the through slot 14 .

[0075] It should be noted that each time the worn plug plate 211 is replaced, the stop block 2221 is used to pull the plug rod 222 upward so that the plug rod 222 inserted in the worn plug plate 211 is pulled out, and then the worn plug plate 211 is pulled out after passing through the through groove 14. In this process, the unworn plug rod 222 remains stationary under the positioning effect of the corresponding plug rod 222, and the second stop groove 212 on one side of the new plug plate 211 is inserted into the second stop rod 213 on one side of the previous set of plug plates 211, and the second stop rod 213 on the other side of the new plug plate 211 is inserted into the next set of plug plates. The replaced plate 211 is then positioned in the second stop groove 212 corresponding to the plate 211. At this time, the new plate 211 is pushed along the through groove 14 to the position where the originally worn plate 211 is installed, and the insertion rod 222 is inserted into the stop hole 214 corresponding to the replaced plate 211 along the first clamping hole 2211, and the lower end of the insertion rod 222 is inserted into the corresponding second clamping hole 2231 to complete the positioning of the replaced plate 211. By arranging the plates 211 into multiple pieces, when the plate in the convex groove is repaired and replaced, only the damaged single plate 211 needs to be replaced, and the replacement efficiency is low and the use cost is low.
