Description

Technical Field

[0001] This invention relates to the field of coal retaining devices for chutes, and more particularly to a 40T coal retaining plate for chutes. Background Technology

[0002] The 40T chute is a central chute, which is mainly used in underground scraper conveyors and transfer conveyors in coal mines. The central chute is the body of the scraper conveyor, consisting of a middle plate and chute sides. The upper chute transports coal, and the lower chute is used for the return of the scraper chain. During the conveying and transfer process, coal blocking plates are needed to shield the coal blocks.

[0003] The 40T chute retaining plates of existing underground scraper conveyors in coal mines are mostly fixed with bolts, making the installation process cumbersome and inefficient. Moreover, when the coal mining machine is working, the amount of coal cut by the machine varies each time, resulting in different impacts on the 40T chute retaining plates. When the 40T chute retaining plate is subjected to a large impact, it will loosen, and long-term impact can easily damage the retaining plate.

[0004] To address this, we have developed a 40T chute coal retaining plate that is easy to install and can withstand strong impacts. Summary of the Invention

[0005] To overcome the shortcomings of cumbersome and inefficient installation process and loosening of the coal retaining plate due to strong impact, the technical problem to be solved is to provide a 40T chute coal retaining plate that is easy to install and can withstand strong impact.

[0006] The technical implementation scheme of the present invention is as follows: a 40T chute coal retaining plate includes a first support plate, a bent baffle, a rib frame, rubber sealing strips, a buffer mechanism, a clamping mechanism, a locking mechanism, a rotating mechanism, and a connecting mechanism. The bent baffle is fixedly connected to the upper surface of the first support plate. The rear surface of the rib frame is fixedly connected to the front side of the bent baffle.

The connecting mechanism is fixedly connected to the rear side of the bent baffle.

[0007] A further technical solution involves a concave bending baffle to increase its impact resistance, a triangular shape below the rib frame for supporting the coal retaining plate, and a rubber sealing strip for sealing between two adjacent coal retaining plates.

[0008] A further technical solution includes a buffer mechanism comprising a buffer plate, a first blind hole post, a first spring, and a second blind hole post. Several buffer plates are provided, and these buffer plates are slidably disposed between the ribs. Several first blind hole posts, first springs, and second blind hole posts are also provided.

Several first springs are provided, and these first springs are fixedly connected between several first blind hole posts and several second blind hole posts.

[0009] A further advanced technical solution involves providing bosses on the buffer plates, which are then pressed together from bottom to top. This means that when the lower buffer plate moves backward, it causes all the buffer plates to move backward.

[0010] A further technical solution includes a clamping mechanism comprising a second support plate, a fixed plate, a second spring, a sliding plate, an N-shaped frame, a splined slider, an L-shaped slider, and a sliding column.

The sliding plate is slidably disposed in the middle of the second support plate. Three second springs are provided, and the three second springs are evenly fixed between the fixed plate and the sliding plate. Two sets of N-shaped frames, splined sliders, L-shaped sliders, and sliding columns are provided and are respectively located on the second support plate.

Several spline grooves are provided on the N-shaped frame. The spline slider is slidably set on the spline groove of the N-shaped frame. The L-shaped slider slides in the upper part of the rear wall of the N-shaped frame. The oblique protrusion at the front of the L-shaped slider cooperates with the oblique protrusion at the upper part of the spline slider. The sliding column slides in the middle part of the rear wall of the N-shaped frame. The cylindrical surface of the middle part of the sliding column is rough. The hole in the middle part of the rear wall of the N-shaped frame is larger than the cylindrical surface of the middle part of the sliding column. The rear end of the sliding column is fixedly connected to the lower end of the L-shaped slider.

[0011] A further technical solution includes a locking mechanism comprising a fixed frame, a fixed block, a first rotating column, a rubber belt, a second rotating column, a pull rod, a sliding protrusion, a third spring, and an L-shaped locking block. Two sets of locking mechanisms are provided, each located on one of two N-shaped frames. The fixed frame is fixed to the rear surface of the N-shaped frame. Four fixed blocks are provided, each in pairs fixed to the upper left and right walls of the fixed frame. The first rotating column is rotatably positioned between the two fixed blocks on the right side of the fixed frame. The right end of the rubber belt is fixed to the middle of the first rotating column.

The pull rod is fixed to the middle of the second rotating column, and the protrusion in the middle of the pull rod is fixed to the left end of the rubber belt. The sliding protrusion is slidably positioned inside the lower left side wall of the pull rod. The third spring is fixed between the sliding protrusion and the pull rod. The third rotating column is rotatably positioned at the lower part of the fixed frame. The L-shaped locking block is fixed to the rear end of the third rotating column.

[0012] A further technical solution includes a rotating mechanism comprising a rotating shaft, a torsion spring, an arc-shaped slider, a fixed post, and a fourth spring. The lower end of the rotating shaft is fixedly connected to a blind hole in the middle of the second support plate, and the upper end of the rotating shaft is located in the middle of the first support plate and rotatably connected to it. The torsion spring is fixedly connected between the first support plate and the second support plate. The first support plate and the second support plate are respectively provided with four arc-shaped sliding grooves. The arc-shaped sliding grooves of the first support plate and the arc-shaped sliding grooves of the second support plate are symmetrical vertically. Each pair of vertically symmetrical arc-shaped sliding grooves is provided with four arc-shaped sliders, two fixed posts, and two fourth springs. The four arc-shaped sliders are paired up and fixedly connected by two fixed posts to form two I-shaped sliders. Two fourth springs are provided between the two I-shaped sliders located in the same arc-shaped sliding groove. The two fourth springs are respectively fixed between the arc-shaped sliders of the two I-shaped sliders.

[0013] A further technical solution involves using arc-shaped sliders at both ends of the I-shaped slider to assist in supporting the coal retaining plate.

[0014] A further technical solution includes a connecting mechanism comprising a first connecting block, a second connecting block, a third connecting block, a positioning post, a wedge-shaped protrusion, a fifth spring, a cylindrical protrusion, and a fourth connecting block.

[0015] The beneficial effects are as follows: The concave shape of the bent baffle and the rib frame of the present invention enable the coal retaining plate to withstand the continuous impact of coal blocks on the coal retaining plate. At the same time, the mutual compression of the buffer mechanism disperses all the impact of coal blocks on the coal retaining plate onto the buffer mechanism, enabling the coal retaining plate to be used for a long time and improving the fixing reliability of the coal retaining plate. The clamping mechanism and connecting mechanism of the coal retaining plate make the installation between the coal retaining plates simple and improve the work efficiency of the installation process. The locking mechanism of the coal retaining plate makes the clamping mechanism more secure. Attached Figure Description

[0031] A 40T coal chute retaining plate, such as Figure 1 and Figure 2 As shown, the device includes a first support plate 1, a bent baffle 101, a rib frame 102, a rubber sealing strip 103, a buffer mechanism, a clamping mechanism, a locking mechanism, a rotating mechanism, and a connecting mechanism. The bent baffle 101 is fixedly connected to the upper surface of the first support plate 1. The bent baffle 101 is concave 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 triangular for supporting the coal retaining plate. A rubber sealing strip 103 is also included. There are two strips 103. The two rubber sealing strips 103 are fixed to the left and right ends of the bent baffle 101 respectively. The rubber sealing strips 103 are used for sealing between two adjacent coal retaining plates. The buffer mechanism is set on the rib frame 102 to improve the firmness of the coal retaining plate. The clamping mechanism is fixed to the lower surface of the first support plate 1. The locking mechanism is fixed to the clamping mechanism. The rotating mechanism is set 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, locking mechanism and connecting mechanism are used to facilitate the installation of the coal retaining plate.

[0032] Mining equipment is installed sequentially inside the coal mine. When installing a coal retaining plate on a 40T chute, multiple retaining plates are manually removed and installed from the beginning to the end of the 40T chute. During installation, the locking and clamping mechanisms are first opened. Then, holding the top of the retaining plate, the clamping mechanism at the bottom of the plate is inserted into the side wall of the 40T chute. The retaining plate is then manually pressed downwards to ensure the clamping mechanism firmly grips the side wall. The locking mechanism is then closed to secure the retaining plate firmly to the side wall. The next retaining plate is then installed on the 40T chute. Similarly, the locking and clamping mechanisms are opened first, and then the clamping mechanism at the bottom of the retaining plate is inserted into the side wall. At this point, attention must be paid to the connecting mechanism to ensure a tight fit between adjacent retaining plates. The retaining plate is then pressed downwards to close the locking mechanism, and the retaining plates are installed sequentially on the side wall of the 40T chute.

The second support plate 3 is fixedly connected to the lower surface of the first support plate 1. The fixed plate 301 is fixedly connected to the rear side of the middle part of the second support plate 3. The sliding plate 303 is slidably disposed in the middle part of the second support plate 3. Three second springs 302 are provided, and the three second springs 302 are evenly fixedly connected between the fixed plate 301 and the sliding plate 303. The N-shaped frame 304, spline slider 306, L-shaped slider 307, and sliding column 308 are provided in two sets and are respectively located on the left and right sides of the second support plate 3. 4. Fixedly connected to the lower surface of the second support plate 3, the N-shaped frame 304 has four spline slide grooves 305, the spline slider 306 slides in the spline slide 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 column 308 slides in the middle part of the rear wall of the N-shaped frame 304, the cylindrical surface of the middle part of the slide column 308 is rough for locking mechanism, the hole in the middle part of the rear wall of the N-shaped frame 304 is larger than the cylindrical surface of the middle part of the slide column 308 for the slide column 308 to slide flexibly on the N-shaped frame 304, the rear end of the slide column 308 is fixedly connected to the lower end of the L-shaped slider 307.

[0035] 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 locking block 409. Two sets of locking mechanisms are provided, each fixedly mounted on the rear surface of one of the two N-shaped frames 304. The rear surface of the fixed frame 4 is fixedly connected to the N-shaped frame 304. Four fixed blocks 401 are provided, each fixedly connected in pairs to the left and right walls of the upper part of the fixed frame 4. The first rotating column 402 is rotatably positioned between the two fixed blocks 401 on the right side 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 positioned between the two fixed blocks 401 on the right side of the fixed frame 4. Between the two fixed blocks 401 on the left side of the fixed frame 4, the pull rod 405 is fixedly connected to the middle of the second rotating column 404. 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 of the lower part 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 in the lower part of the fixed frame 4. The L-shaped locking block 409 is fixedly connected to the rear end of the third rotating column 408. The right part of the L-shaped locking block 409 is inclined at the contact point with the sliding protrusion 406 to facilitate the L-shaped locking block 409 passing through the sliding protrusion 406 and realizing the locking action of the sliding protrusion 406.

[0036] like Figure 11 and Figure 12 As shown, the connecting mechanism includes a first connecting block 6, a second connecting block 601, a third connecting block 602, a positioning post 603, a wedge-shaped protrusion 604, a fifth spring 605, a cylindrical protrusion 606, and a fourth connecting block 607. The first connecting block 6 is fixedly connected to the lower left part of the rear surface of the first support plate 1. The protrusion on the left side of the first connecting block 6 has a chamfer. The second connecting block 601 is fixedly connected to the lower right part of the rear surface of the first support plate 1. The blind hole on the right side of the second connecting block 601 has a chamfer for easy fixing when installing adjacent coal retaining plates. The third connecting block 602 is fixedly connected to the upper left part of the rear surface of the first support plate 1. The positioning post... The lower surface of 603 is fixed 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 disposed in the upper part of the positioning post 603. The fifth spring 605 is fixedly connected between the two wedge-shaped protrusions 604. The cylindrical protrusion 606 is slidably disposed on the top of the positioning post 603. The cylindrical protrusion 606 cooperates with the two wedge-shaped protrusions 604. The fourth connecting block 607 is fixed to the upper right part of the rear surface of the first support plate 1. The lower part of the through hole on the right side of the fourth connecting block 607 is chamfered, so that the positioning post 603 on the third connecting block 602 can easily and conveniently enter the through hole of the fourth connecting block 607.

[0037] When installing the coal retaining plate, first press the sliding protrusion 406 to rotate the L-shaped locking block 409 to release the restriction on the pull rod 405. Then, rotate the pull rod 405 to loosen the rubber belt 403. Next, pull the L-shaped slider 307 backward, and then press the coal retaining plate against the side wall of the 40T chute. The sliding plate 303 slides backward due to the pressure from the side wall of the 40T chute. Under the action of the second spring 302, the sliding plate 303 remains in close contact with the side wall of the 40T chute. As the coal retaining plate presses down, the spline slider 306 contacts the upper end of the side wall of the 40T chute and moves upward. As the spline slider 306 moves upward, it drives the sliding column 308 forward through the L-shaped slider 307. With the force of pressing the coal retaining plate, the sliding column 308 tightly squeezes the side wall of the 40T chute. Then, the pull rod 405 is rotated to make the rubber belt 403 taut, so that the rubber belt 403 is in close contact with the sliding column 308. Then, the L-shaped locking block 409 is rotated, and the L-shaped locking block 409 rotates to squeeze the sliding protrusion 406. As the L-shaped locking block 409 passes the sliding protrusion 406, the sliding protrusion 406 is popped out by the third spring 407 and locks the L-shaped locking block 409.

[0038] Then install the next coal retaining plate. Similarly, open the locking mechanism and clamping mechanism, and then install the coal retaining plate onto the side wall of the next 40T chute. Put the second connecting block 601 and the fourth connecting block 607 of the coal retaining plate onto the first connecting block 6 and the third connecting block 602 of the already installed coal retaining plate. The third connecting block 602 is put onto the positioning post 603 of the fourth connecting block 607. As the third connecting block 602 moves down, the third connecting block 602 squeezes the two wedge-shaped protrusions 604 and slides inward. When the third connecting block 602 passes the wedge-shaped protrusions 604, the two wedge-shaped protrusions 604 pop out and lock the fourth connecting block 607 under the action of the fifth spring 605. At the same time, the second connecting block 601 is put onto the first connecting block 6. Then, the coal retaining plate is pressed down manually, and then the locking mechanism is closed to further clamp the clamping mechanism. The coal retaining plates are installed on the entire side wall of the 40T chute in sequence.

[0039] When removing the coal retaining plates after mining is completed, first press the sliding protrusion 406 to rotate the L-shaped locking block 409 to release the restriction on the pull rod 405. Then rotate the pull rod 405 to loosen the rubber belt 403. Then, manually hold the upper part of the coal retaining plate and press the cylindrical protrusion 606 at the same time. Shake the coal retaining plate to loosen the pressure of the sliding column 308 on the side wall of the 40T chute. Then pull out the coal retaining plate and remove all the coal retaining plates on the entire 40T chute in sequence.

[0040] Example 3

[0041] Based on Example 2, such as Figures 1-3As shown, the buffer mechanism includes a buffer plate 2, a first blind hole post 201, a first spring 202, and a second blind hole post 203. A plurality of buffer plates 2 are provided, and the plurality of buffer plates 2 are slidably disposed between the rib frame 102. The buffer plates 2 are provided with protrusions. The buffer plates 2 are pressed sequentially from bottom to top, that is, the lower buffer plate 2 moves backward, which will drive all the buffer plates 2 to move backward. A plurality of first blind hole posts 201, first springs 202, and second blind hole posts 203 are provided. The plurality of first blind hole posts 201 are evenly distributed in the middle of the bent baffle 101, and the rear end of the first blind hole post 201 is fixedly connected to the bent baffle 101. A plurality of second blind hole posts 203 are slidably disposed on the plurality of first blind hole posts 201. A plurality of first springs 202 are provided, and the plurality of first springs 202 are fixedly connected between the plurality of first blind hole posts 201 and the plurality of second blind hole posts 203.

[0042] like Figure 9 and Figure 10 As shown, the rotating mechanism includes a rotating shaft 5, a torsion spring 501, an arc-shaped slider 503, a fixed column 504, and a fourth spring 505. The lower end of the rotating shaft 5 is fixedly connected to a blind hole in the middle of the second support plate 3, and the upper end of the rotating shaft 5 is located in the middle of the first support plate 1 and rotatably connected to it. The torsion spring 501 is fixedly connected between the first support plate 1 and the second support plate 3. Four arc-shaped grooves 502 are respectively provided on the first support plate 1 and the second support plate 3. The arc-shaped grooves 502 of the first support plate 1 and the arc-shaped grooves 502 of the second support plate 3 are symmetrical vertically. Four arc-shaped sliders 503 and two fixed columns are provided in each pair of vertically symmetrical arc-shaped grooves 502. The four arc-shaped sliders 503 are fixed in pairs by two fixed columns 504 to form two I-shaped sliders. Two fourth springs 505 are set between the two I-shaped sliders located in the same arc-shaped groove 502. The two fourth springs 505 are fixed between the arc-shaped sliders 503 of the two I-shaped sliders. Two arc-shaped sliders 503 are set in the same arc-shaped groove 502. The two arc-shaped sliders 503 are located at both ends of the arc-shaped groove 502 under the action of the fourth springs 505. The arc-shaped sliders 503 slide in the first support plate 1 and the second support plate 3 for coal retaining plate support.

[0043] When mining begins in the coal mine, the coal mining machine cuts the coal off. The coal blocks collapse, tilt, and slide onto the 40T chute, impacting the coal retaining plate fixed to the side wall of the 40T chute. The buffer plate 2 on the bent baffle 101 is impacted and moves backward, driving the second blind hole column 203 to press the first spring 202, thus relieving the impact force on the coal retaining plate and giving it a sufficiently long service life. After the coal mining machine completes one stroke, it advances into the coal mine while simultaneously advancing the 40T chute. During this advancement, the entire 40T chute inevitably tilts. At this time, the coal retaining plate on the tilted section of the 40T chute twists accordingly, the second support plate 3 rotates and twists the torsion spring 501, and at the same time, the second support plate 3 rotates and squeezes the corresponding arc-shaped slider 503, which in turn squeezes the fourth spring 505. After the advancement is completed, the entire 40T chute is leveled.

[0044] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of the invention. Therefore, the scope of the invention should be limited only by the appended claims.
