[0002] The 40T chute is the middle chute, which is mainly used for scraper conveyors and transfer machines in coal mines. The middle chute is the body of the scraper conveyor, which is composed of a middle plate and trough sides. The upper chute is used to transport coal, and the lower chute is used for the return of the scraper chain. Coal blocks are required to block coal blocks during the transportation and transfer process.

[0003] The 40T chute coal retaining plate of the existing scraper conveyor in underground coal mines is mostly fixed with bolts, which makes the installation process of the existing 40T chute coal retaining plate cumbersome and inefficient. When the coal mining machine is working, the amount of coal cut by the coal mining machine each time is different, so that the impact of the cut coal blocks on the 40T chute coal retaining plate is different.

The upper surface of the first support plate 1 is fixedly connected with the bent baffle 101, and the bent baffle 101 is concave, which is used to increase the impact resistance of the baffle. The rear surface of the rib frame 102 is fixedly connected to the front side of the bent baffle 101, and the lower surface of the rib frame 102 is fixedly connected to the upper surface of the first support plate 1. The lower part of the rib frame 102 is a triangle for supporting the coal baffle. The rubber sealing strip 103 is provided at the bottom of the rib frame 102. Two strips 103 are provided, and the two rubber sealing strips 103 are respectively fixed to the left and right ends of the bent baffle 101, and the rubber sealing strip 103 is used for sealing between two adjacent coal baffles. The buffer mechanism is arranged on the rib frame 102, and is used to improve the firmness of the coal baffle. The clamping mechanism is fixed to the lower surface of the first support plate 1, and the locking mechanism is fixed to the clamping mechanism. The rotating mechanism is arranged between the first support plate 1 and the clamping mechanism. The connecting mechanism is fixed to the rear side of the bent baffle 101. The clamping mechanism, the locking mechanism and the connecting mechanism are used for easy installation of the coal baffle.

[0036] In addition, the embodiment of the present invention is also based on the above-mentioned 40T chute coal retaining plate, such as Fig.13 As shown, a 40T chute coal retaining plate installation method is proposed to overcome the shortcomings of cumbersome and inefficient installation process and loosening of the coal retaining plate due to large impact.

[0037] Specifically, a method for installing a 40T chute coal retaining plate includes the following steps:

[0038] Mining equipment is installed in the coal mine in sequence. When installing the coal baffle plate on the entire 40T chute, multiple coal baffle plates are taken out manually and installed from the starting point of the 40T chute to the end of the 40T chute. When installing the coal baffle plate, the locking mechanism and the clamping mechanism are first opened, and then the top of the coal baffle plate is held to insert the clamping mechanism at the lower part of the coal baffle plate into the side wall of the 40T chute, and the coal baffle plate is manually squeezed downward with force so that the clamping mechanism tightly clamps the side wall of the 40T chute, and then the locking mechanism is closed to firmly fix the coal baffle plate on the side wall of the 40T chute; then the next coal baffle plate is taken and installed on the 40T chute. Similarly, the locking mechanism and the clamping mechanism are first opened, and then the top of the coal baffle plate is held to insert the clamping mechanism at the lower part of the coal baffle plate into the side wall of the 40T chute. At this time, attention should be paid to the connecting mechanism to ensure that the connecting mechanisms of adjacent coal baffle plates are closely matched, and then the coal baffle plate is squeezed downward with force to close the locking mechanism, and the coal baffle plates are installed on the side walls of the 40T chute in sequence.

The N-shaped frame 304, the spline slider 306, the L-shaped slider 307 and the slide column 308 are arranged in two groups and are respectively located at the left and right parts of the second support plate 3. The N-shaped frame 304 is fixedly connected to the lower surface of the second support plate 3. Four spline grooves 305 are provided on the N-shaped frame 304. The spline slider 306 slides in the spline grooves 305 of the N-shaped frame 304. The L-shaped slider 307 slides in the upper part of the rear wall of the N-shaped frame 304. The oblique protrusion at the front of the L-shaped slider 307 cooperates with the oblique protrusion at the upper part of the spline slider 306. The slide post 308 slides in the middle part of the rear wall of the N-shaped frame 304. The surface of the middle cylinder of the slide post 308 is rough, which is used for locking the locking mechanism. The hole in the middle part of the rear wall of the N-shaped frame 304 is larger than the middle cylinder of the slide post 308, which is used for the slide post 308 to slide flexibly on the N-shaped frame 304. The rear end of the slide post 308 is fixedly connected to the lower end of the L-shaped slider 307.

[0041] like Figure 4 , Figure 6 and Figure 8As shown, the locking mechanism includes a fixed frame 4, a fixed block 401, a first rotating column 402, a rubber belt 403, a second rotating column 404, a pull rod 405, a sliding protrusion 406, a third spring 407, a third rotating column 408 and an L-shaped block 409. The locking mechanism is provided with two groups, and the two groups of locking mechanisms are respectively fixedly arranged on the rear surfaces of the two N-type frames 304. The rear surface of the N-type frame 304 of the fixed frame 4 is fixedly connected to the fixed frame 4. There are four fixed blocks 401. The four fixed blocks 401 are respectively fixedly connected to the left and right walls of the upper part of the fixed frame 4 in groups of two. The first rotating column 402 is rotatably arranged between the two fixed blocks 401 on the right part of the fixed frame 4. The right end of the rubber belt 403 is fixedly connected to the middle of the first rotating column 402. The second rotating column 404 is rotatably arranged The pull rod 405 is fixedly connected to the middle of the second rotating column 404, and the boss in the middle of the pull rod 405 is fixedly connected to the left end of the rubber belt 403. The rubber belt 403 is used to tighten the rough cylinder in the middle of the sliding column 308 to further lock the clamping mechanism. The sliding protrusion 406 slides in the left side wall at the bottom of the pull rod 405. The third spring 407 is fixedly connected between the sliding protrusion 406 and the pull rod 405. The third rotating column 408 is rotatably set at the bottom of the fixed frame 4. The L-shaped clamping block 409 is fixedly connected to the rear end of the third rotating column 408. The right part of the L-shaped clamping block 409 is inclined at the contact with the sliding protrusion 406, which is convenient for the L-shaped clamping block 409 to pass through the sliding protrusion 406 to achieve the clamping action of the sliding protrusion 406.

[0042] like Fig.11 and Fig.12 As shown, the connection mechanism includes a first connection block 6, a second connection block 601, a third connection block 602, a positioning column 603, a wedge-shaped protrusion 604, a fifth spring 605, a cylindrical protrusion 606 and a fourth connection block 607. The first connection block 6 is fixedly connected to the lower left part of the rear surface of the first support plate 1, and the protrusion on the left part of the first connection block 6 is chamfered. The second connection block 601 is fixedly connected to the lower right part of the rear surface of the first support plate 1, and the blind hole on the right part of the second connection block 601 is chamfered for easy fixing of adjacent coal baffles during installation. The third connection block 602 is fixedly connected to the upper left part of the rear surface of the first support plate 1, and the positioning column The lower surface of 603 is fixedly connected to the upper surface of the third connecting block 602, two wedge-shaped protrusions 604 are provided, and the two wedge-shaped protrusions 604 are slidably set in the upper part of the positioning column 603, and the fifth spring 605 is fixedly connected between the two wedge-shaped protrusions 604. The cylindrical protrusion 606 is slidably set on the top of the positioning column 603, and the cylindrical protrusion 606 cooperates with the two wedge-shaped protrusions 604. The fourth connecting block 607 is fixedly connected to the upper right part of the rear surface of the first supporting plate 1, and the lower part of the through hole on the right part of the fourth connecting block 607 is chamfered, so that the positioning column 603 on the third connecting block 602 can smoothly and easily enter the through hole of the fourth connecting block 607.

[0043] When installing the coal baffle plate, first press the sliding protrusion 406 to rotate the L-shaped block 409 to release the restriction on the pull rod 405, then rotate the pull rod 405 to loosen the rubber belt 403, and then pull the L-shaped slider 307 backwards, and then press the coal baffle plate against the side wall of the 40T chute. The sliding plate 303 slides backwards due to the pressure of the side wall of the 40T chute. The sliding plate 303 is always close to the side wall of the 40T chute under the action of the second spring 302. As the coal baffle plate is pressed down, the spline slider 306 contacts the upper end of the side wall of the 40T chute and moves upward. The spline slider 306 moves upward through the L-shaped slider 307 to drive the slide column 308 to move forward. As the coal baffle plate is pressed hard, the slide column 308 is tightly pressed against the side wall of the 40T chute. Then the pull rod 405 is rotated to tighten the rubber belt 403, so that the rubber belt 403 is close to the slide column 308. Then the L-shaped block 409 is rotated. The L-shaped block 409 rotates and squeezes the sliding protrusion 406. As the L-shaped block 409 passes the sliding protrusion 406, the sliding protrusion 406 is popped out by the third spring 407 and clamps the L-shaped block 409.

[0044] Then install the next coal baffle plate, open the locking mechanism and the clamping mechanism in the same way, and then install the coal baffle plate on the next 40T chute side wall, and put the second connecting block 601 and the fourth connecting block 607 of the coal baffle plate onto the first connecting block 6 and the third connecting block 602 on which the coal baffle plate has been installed, and the third connecting block 602 is put on the positioning column 603 of the fourth connecting block 607. As the third connecting block 602 moves downward, the third connecting block 602 squeezes the two wedge-shaped protrusions 604 to slide inward. After the third connecting block 602 passes the wedge-shaped protrusions 604, the two wedge-shaped protrusions 604 pop out again under the action of the fifth spring 605 and clamp the fourth connecting block 607. At the same time, the second connecting block 601 is put on the first connecting block 6. Then, continue to press the coal baffle plate manually, and then close the locking mechanism to further clamp the clamping mechanism, and install the coal baffle plate on the entire 40T chute side wall in turn.

[0045] When removing the coal baffle plate after mining is completed, first press the sliding protrusion 406 to rotate the L-shaped block 409 to release the restriction on the pull rod 405, then rotate the pull rod 405 to loosen the rubber belt 403, and then manually hold the upper end of the coal baffle plate and press the cylindrical protrusion 606 at the same time, shake the coal baffle plate to loosen the squeezing of the slide column 308 on the side wall of the 40T chute, and then pull out the coal baffle plate, and remove all the coal baffle plates on the entire 40T chute in turn.

[0046] Example 3

[0047] On the basis of Example 2, Figure 1-Figure 3As shown, the buffer mechanism includes a buffer plate 2, a first blind hole column 201, a first spring 202 and a second blind hole column 203. There are a plurality of buffer plates 2, which are slidably arranged between the rib frame 102. The buffer plate 2 is provided with a boss, which squeezes the buffer plates 2 from bottom to top in sequence, that is, the lower buffer plate 2 moves backward and all the buffer plates 2 move backward. There are a plurality of first blind hole columns 201, a first spring 202 and a second blind hole column 203, which are evenly distributed in the middle of the bending baffle 101, and the rear end of the first blind hole column 201 is fixedly connected to the bending baffle 101. A plurality of second blind hole columns 203 are respectively slidably arranged on a plurality of first blind hole columns 201. There are a plurality of first springs 202, which are respectively fixedly connected between a plurality of first blind hole columns 201 and a plurality of second blind hole columns 203.

[0048] like Fig. 9 and Fig.10 As shown, the rotating mechanism includes a rotating shaft 5, a torsion spring 501, an arc-shaped slider 503, a fixing column 504 and a fourth spring 505. The lower end of the rotating shaft 5 is fixedly connected to the blind hole in the middle of the second supporting plate 3. The upper end of the rotating shaft 5 is located in the middle of the first supporting plate 1 and is rotatably connected thereto. The torsion spring 501 is fixedly connected between the first supporting plate 1 and the second supporting plate 3. Four arc-shaped slide grooves 502 are respectively provided on the first supporting plate 1 and the second supporting plate 3. The arc-shaped slide grooves 502 of the first supporting plate 1 are symmetrical with the arc-shaped slide grooves 502 of the second supporting plate 3. Four arc-shaped sliders 503, two fixing columns 504 and a fourth spring 505 are provided in each of two arc-shaped slide grooves 502 that are symmetrical with each other. Fixed column 504 and two fourth springs 505, four arc-shaped sliding blocks 503 are respectively fixedly connected by two fixed columns 504 in pairs to form two I-shaped sliding blocks, two fourth springs 505 are arranged between the two I-shaped sliding blocks in the same arc-shaped slide groove 502, the two fourth springs 505 are respectively fixedly connected between the arc-shaped sliding blocks 503 of the two I-shaped sliding blocks, two arc-shaped sliding blocks 503 are arranged in the same arc-shaped slide groove 502, and the two arc-shaped sliding blocks 503 are respectively located at two ends of the arc-shaped slide groove 502 under the action of the fourth springs 505, and the arc-shaped sliding blocks 503 slide in the first support plate 1 and the second support plate 3, and are used for supporting the coal blocking plate.

[0049] When mining begins in the coal mine, the coal mining machine cuts the coal, and the coal blocks collapse, tilt and slide onto the 40T chute to impact the coal blocking plate fixed on the side wall of the 40T chute. The buffer plate 2 on the bent baffle 101 of the coal blocking plate is impacted backward and drives the second blind hole column 203 to press the first spring 202, thereby alleviating the impact force on the coal blocking plate and ensuring that the coal blocking plate has a sufficiently long service life. After the coal mining machine has worked for one stroke, the coal mining machine advances into the coal mine and at the same time advances the 40T chute. During the advancement process, the entire section of the 40T chute is inevitably tilted. At this time, the coal blocking plate on the inclined section of the 40T chute undergoes corresponding twisting, and the second support plate 3 rotates and twists the torsion spring 501.
