Description

Technical Field

[0001] The invention relates to the technical field of coal mining, in particular to a novel coal flow buffer device. Background Art

[0002] Coal mines are areas where humans extract coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. During underground mining, coal conveyors are typically installed inside the mine. These conveyors move coal from higher locations to lower locations. The coal is then transported through the lower-level coal conveying chamber and coal flow unloading bin to the coal transport vehicles at the bottom of the mine, achieving unified coal transportation.

[0003] However, the coal flow unloading bin has the following defects when used: 1. When the existing coal flow unloading bin transports and unloads the mined coal transported by the coal conveyor, the coal is generally tilted into the coal flow unloading bin because the coal conveyor is generally set at an angle (the efficiency of coal transportation is improved by using the inclined coal conveyor). However, when the mined coal falls into the coal flow unloading bin, the impact force of the coal falling directly collides with the inner wall of the coal flow unloading bin, which can easily cause serious damage to the inner wall of the coal flow unloading bin and shorten its service life. 2. The existing coal flow unloading bin buffers its internal activities and the flow of coal being discharged to ensure the life of the coal flow unloading bin. The coal flow buffer device needs to be continuously impacted by the coal flow for a long time. In addition, the impact force and speed of coal unloading are relatively large, and the coal flow buffer device is often prone to damage. Therefore, the coal flow buffer device needs to be regularly maintained and damaged parts replaced. At this time, the cost of traditional coal flow buffer devices is relatively high, and the degree of damage to internal parts varies, making it difficult to quickly maintain and replace damaged parts. At the same time, the cost and time of maintenance and overhaul of the coal flow buffer device are high, which is not conducive to the normal mining and transportation of coal mines. Summary of the Invention

[0004] The purpose of the present invention is to provide a novel coal flow buffer device to solve the problems raised in the above background technology.

A buffer ring chain is installed and positioned on the inner side of the ring chain mounting assembly, and a buffer ring chain is installed on the outer side of the linear buffer assembly.

[0006] As a preferred solution of the present invention, a coal screen is installed inside the coal flow unloading bin, and the coal screen is arranged below the buffer chain. A through hole is opened inside the coal screen for the movement of coal unloading. Wherein, the distance between the coal mine screen and the bottom of the buffer chain is set between 300 and 500 mm.

[0007] As a preferred embodiment of the present invention, the support and positioning assembly includes: a vertical I-beam installed on the inner wall of the coal mine conveying chamber by screws; a horizontal I-beam installed on the side of the vertical I-beam by screws; a lower metal plate installed at the bottom of the horizontal I-beam by screws; and a plurality of positioning brackets welded to the bottom of the lower metal plate. Wherein, a linear buffer component is fixedly installed on the inner side of the bottom of the positioning bracket.

[0008] As a preferred solution of the present invention, an L-shaped mounting bracket located on the side of the lower metal plate is mounted on the bottom of the horizontal I-beam by screws, and a side positioning seat is mounted on the side of the L-shaped mounting bracket by screws, and the side positioning seat is mounted on the side of the chain mounting assembly by screws. There are two L-shaped mounting brackets and two side positioning seats, and the two L-shaped mounting brackets and two side positioning seats are respectively arranged on the rightmost and leftmost sides of the plurality of buffer chains.

[0009] As a preferred embodiment of the present invention, the linear buffer assembly includes: a linear assembly rod mounted on the side of the first connecting seat by screws; a positioning metal ring mounted on the outside of the linear assembly rod; a chain assembly ring provided on the side of the positioning metal ring and mounted on the outside of the linear assembly rod, Wherein, the outer side of the chain assembly ring is assembled with a chain ring.

[0010] As a preferred embodiment of the present invention, two chain assembly rings are provided on the outer side of one of the positioning metal rings, and one positioning metal ring is provided on both the left and right sides of one of the chain assembly rings. Wherein, a buffer spring located outside the linear assembly rod is installed on the side surface of the positioning metal ring, and the buffer spring is connected to the side surface of the chain assembly ring through a damping block.

[0011] As a preferred embodiment of the present invention, the first connecting seat rotates in the Z-axis direction around the shaft end of the first assembly seat, and the second connecting seat rotates in the Y-axis direction around the shaft end of the second assembly seat. Wherein, the side surfaces of the first connecting seat located at the leftmost end and the rightmost end are mounted with the side positioning seats by screws.

[0012] As a preferred embodiment of the present invention, the chain mounting assembly includes: a side mounting bracket connected to the second assembly base by screws; an intermediate metal block mounted on the inner side of the side mounting bracket by screws; and metal collars mounted on the front and rear sides of the intermediate metal block by screws. Wherein, side mounting supports are mounted on both the left and right sides of one of the middle metal blocks by screws, the two side mounting supports are in contact with each other, and a chain ring is mounted and fixed on the inner side of the metal ring.

[0013] As a preferred embodiment of the present invention, the lateral positioning assembly includes: a lateral chain connected to the outer side of the inner chain link of the buffer chain; a lateral support sleeved on the outer side of the lateral chain; and a mounting metal seat mounted on the side of the lateral support by screws.

[0014] As a preferred solution of the present invention, the transverse ring chain is composed of a plurality of chain links, two transverse ring chains are provided, and the transverse support is fixedly installed on the outer side of the chain link inside the transverse ring chain. The two transverse links divide the buffer chain into three parts, and the buffer chain part between the two transverse links is smaller than the upper and lower parts of the buffer chain.

[0015] Compared with the existing technology, one or more of the above technical solutions have the following beneficial effects: 1. In the new coal flow buffer device, when the coal is mined and transported through the coal conveyor after mining, it can be used to block and buffer the unloading coal through multiple vertical buffer chains, reducing the probability of the coal with large impact force directly colliding with the inner wall of the coal flow unloading bin and causing damage to the coal flow unloading bin, thereby improving the service life of the coal flow unloading bin. At the same time, the multiple buffer chains that buffer and block the coal flow can directly buffer the impact force through buffer springs and damping blocks, while the other part (relative to half of the upper part) can indirectly buffer through buffer springs and damping blocks. While ensuring the buffer chain is buffered, the range of movement and activity of the buffer chain under impact is minimized to the greatest extent, preventing the buffer chain from colliding with the inner wall of the coal flow unloading bin due to excessive impact force from the coal. 2. In the new coal flow buffer device, multiple buffer chains that are installed vertically to buffer and block the impact of coal unloading can be installed using two horizontal chains. On the one hand, this allows for the assembly and positioning of multiple buffer chains, while ensuring the contact area between the unloading coal and the buffer chains, while reducing the risk of multiple buffer chains getting entangled (reducing the contact area with the coal). On the other hand, when the coal comes into contact with one or more buffer chains, the impact force generated will act on all buffer chains. The weight of the multiple buffer chains further enhances the blocking and buffering effect of the coal, making it suitable for different coal unloading trajectories. 3. In the new coal flow buffer device, the position-adjustable chain links (chain links assembled to form the buffer chain and transverse chain) ensure that the buffer chain and transverse chain block and buffer the unloading coal. If the internal chain links are damaged due to impact, they can be easily and conveniently disassembled and replaced according to the damaged chain links, reducing the time the device is suspended for maintenance and overhaul, allowing coal mining to continue for a longer period of time. At the same time, replacing damaged chain links is more cost-effective than traditional buffer device maintenance methods, making it suitable for large-scale coal mining and transportation operations. 4. In the new coal flow buffer device, by equipping the tops of multiple buffer chains with connecting seats and assembly seats that can rotate at multiple angles, the buffer chains can be driven to rotate at the same angle according to the angle of the coal discharge impact on the multiple buffer chains, reducing the probability of direct impact force acting on the buffer chains and causing damage to the buffer chains and the structures that mount them. At the same time, the movement and rotation of the buffer chains can provide more time for subsequent buffering of the buffer chains, improving the buffering and shock absorption effect of the buffer chains and reducing the probability of damage to the buffer device.

[0019] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0020] Example 1

[0021] See also Figure 1 and Figure 10A novel coal flow buffer device includes a buffer chain 20 composed of a plurality of chain links 10; a chain assembly buffer mechanism 30 for installing, positioning and assembling the buffer chain 20; a transverse positioning component 50 arranged inside the plurality of buffer chains 20 and installed inside the coal flow discharge bin 40, the coal flow discharge bin 40 is provided with a buffer chain 20, and the buffer chain 20 is arranged on the side of the discharge port of the coal mine conveyor arranged at an angle, and the chain assembly buffer mechanism 30 includes: a support positioning component 301 installed on the inner wall of the coal mine conveying chamber; a linear buffer component 302 installed on the inner side of the bottom of the support positioning component 301 by screws; a first connecting seat installed on the side of the linear buffer component 302 by screws 303; a first assembly seat 304 rotatably connected to the first connecting seat 303; a second connecting seat 305 connected to the first assembly seat 304 by screws; a second assembly seat 3051 rotatably connected to the second connecting seat 305; a chain mounting assembly 306 connected to the second connecting seat 305, wherein a plurality of linear buffer assemblies 302 are provided, and two adjacent linear buffer assemblies 302 are connected via the first connecting seat 303, the first assembly seat 304, the second connecting seat 305, the second assembly seat 3051 and the chain mounting assembly 306, a buffer chain 20 is installed and positioned on the inner side of the chain mounting assembly 306, and a buffer chain 20 is installed on the outer side of the linear buffer assembly 302.

[0022] In the present invention, a coal mine screen 401 is installed inside the coal flow unloading bin 40, and the coal mine screen 401 is arranged below the buffer chain 20. A through hole is opened inside the coal mine screen 401 for coal unloading and movement, wherein the distance between the coal mine screen 401 and the bottom of the buffer chain 20 is set between 300 and 500 mm.

[0023] The above working principle: when the coal flow transported by the coal mine conveyor is unloaded, the coal at the discharge port of the coal mine conveyor will be automatically transported and dropped into the coal flow unloading bin 40 on the side, and the impact force generated by the coal flow will be buffered by multiple buffer chains 20 arranged inside the coal flow unloading bin 40, thereby reducing the probability of the coal flow with greater impact force directly impacting the coal flow unloading bin 40, protecting the inner wall of the coal flow unloading bin 40, and extending the service life of the coal flow unloading bin 40. Among them, when the coal flow collides with the buffer chain 20, its impact force will act on the buffer chain 20. At this time, through the active connection between the first assembly seat 304 and the first connecting seat 303, the second connecting seat 305 and the second assembly seat 3051, it can cooperate with the impact force angle of the complex situation when the coal flow collides with the buffer chain 20, and perform a certain range of rotation. The linear buffer component 302 buffers the impact force during the rotation, reducing the probability of the buffer chain 20 moving to a large extent due to the impact force, and avoiding the buffer chain 20 colliding with the inner wall of the coal flow unloading bin 40 due to the large impact force, which has high safety.

[0024] In the present invention, the design of the transverse positioning assembly 50 allows for the connection and assembly of multiple buffer chains 20. When any position of the multiple buffer chains 20 collides with coal, the multiple buffer chains 20 can move synchronously, ensuring contact area while enhancing the buffering effect. Furthermore, the range of motion of the multiple buffer chains 20 can be restricted, reducing the probability of the buffer chains 20 colliding with the inner wall of the coal discharge bin 40 when the coal stream impacts the buffer chains 20.

[0025] Specific reference Figure 5 and Figure 6 The support and positioning assembly 301 includes: a vertical I-beam 3011 installed on the inner wall of the coal mine conveying chamber by screws; a horizontal I-beam 3012 installed on the side of the vertical I-beam 3011 by screws; a lower metal plate 3013 installed on the bottom of the horizontal I-beam 3012 by screws; and a plurality of positioning brackets 3014 welded and fixed to the bottom of the lower metal plate 3013, wherein a linear buffer assembly 302 is installed and fixed on the inner side of the bottom of the positioning bracket 3014.

[0026] In the present invention, an L-shaped mounting bracket 30121 located on the side of the lower metal plate 3013 is installed at the bottom of the horizontal I-beam 3012 by screws, and a side positioning seat 30122 is installed on the side of the L-shaped mounting bracket 30121 by screws. The side positioning seat 30122 is installed on the side of the chain mounting assembly 306 by screws, wherein two L-shaped mounting brackets 30121 and two side positioning seats 30122 are provided, and the two L-shaped mounting brackets 30121 and side positioning seats 30122 are respectively arranged on the rightmost and leftmost sides of the multiple buffer chains 20.

[0027] In the novel coal flow buffer device of the present invention, the multiple positioning brackets 3014 at the bottom of the lower metal plate 3013, along with the L-shaped mounting brackets 30121 and side positioning seats 30122 on its left and right sides, allow for the installation and positioning of the linear buffer assembly 302 and the chain mounting assembly 306 that support and mount the multiple buffer chains 20. This multi-position mounting and securing method enhances the stability and securement of the multiple buffer chains 20 during installation and positioning, increasing their ability to withstand coal flow impact and their service life.

[0028] Specific reference Figure 7 The linear buffer assembly 302 includes: a linear assembly rod 3021 installed on the side of the first connecting seat 303 by screws; a positioning metal ring 3022 installed on the outside of the linear assembly rod 3021; ​​and a chain assembly ring 3023 arranged on the side of the positioning metal ring 3022 and installed on the outside of the linear assembly rod 3021, wherein the chain assembly ring 10 is installed on the outside of the chain assembly ring 3023.

[0029] In the present invention, two chain assembly rings 3023 are provided on the outside of a positioning metal ring 3022, and a positioning metal ring 3022 is provided on the left and right sides of a chain assembly ring 3023, wherein a buffer spring 30221 located on the outside of the linear assembly rod 3021 is installed on the side of the positioning metal ring 3022, and the buffer spring 30221 is connected to the side of the chain assembly ring 3023 through a damping block.

[0030] In the new coal flow buffer device of the present invention, when the coal flow collides with the buffer chain 20, it will drive the chain assembly ring 3023 connected to the buffer chain 20 to move (due to the impact force of the coal mine at different angles) and push the buffer spring 30221 that contacts the side of the chain assembly ring 3023. The impact force can be buffered by the elastic force of the buffer spring 30221 itself and the absorption of the impact force by the damping block, thereby preventing the buffer chain 20 from colliding with the inner wall of the coal flow unloading bin 40 due to the impact force of the coal mine, thereby ensuring the service life of the coal flow unloading bin 40.

[0031] Specific reference Figure 8 The first connecting seat 303 rotates in the Z-axis direction around the axial end of the first assembly seat 304, and the second connecting seat 305 rotates in the Y-axis direction around the axial end of the second assembly seat 3051, wherein the side surfaces of the first connecting seat 303 located at the leftmost and rightmost ends are installed with side positioning seats 30122 by screws.

[0032] In the novel coal flow buffer device of the present invention, the linear assembly rod 3021 that moves in the Z-axis direction and the Y-axis direction can rotate in any direction when the coal flow collides with the buffer chain 20 (at different impact angles and directions). By driving the buffer chain 20 to move, the path length and capacity of the buffer chain 20 for buffering are extended (through multiple buffer springs 30221), further improving the buffering effect of the buffer chain 20 on the coal flow.

[0033] Specific reference Figure 6 and Figure 8 The chain mounting assembly 306 includes: a side mounting support 3061 connected to the second assembly seat 3051 by screws; an intermediate metal block 3062 mounted on the inner side of the side mounting support 3061 by screws; and metal rings 3063 mounted on the front and rear sides of the intermediate metal block 3062 by screws, wherein the left and right sides of an intermediate metal block 3062 are both mounted with side mounting supports 3061 by screws, the two side mounting supports 3061 are in conflict with each other, and the chain ring 10 is mounted and fixed on the inner side of the metal ring 3063.

[0034] In the novel coal flow buffer device of the present invention, the buffer chain 20 mounted inside the metal collar 3063 is assembled and secured by a metal collar 3063, which secures the chain link 10, and an intermediate metal block 3062, which secures the metal collar 3063. The buffer chain 20 attached to the metal collar 3063 does not itself provide a buffering function; instead, it relies on the buffer springs 30221 on the other buffer chains 20 that move in concert with it. This design ensures the buffering capacity of multiple buffer chains 20 while reducing the range of movement of the buffer chains 20 due to the impact of the coal flow, thereby reducing the probability of the buffer chains 20 colliding with the inner wall of the coal flow discharge bin 40.

[0035] Specific reference Figure 9 and Figure 10 The transverse positioning assembly 50 includes: a transverse chain 501 connected to the outside of the chain link 10 inside the buffer chain 20; a transverse support 502 sleeved on the outside of the transverse chain 501; and a mounting metal seat 503 mounted on the side of the transverse support 502 by screws, wherein the mounting metal seat 503 is mounted on the inner wall of the coal flow unloading bin 40 by screws.

[0036] In the present invention, the transverse chain 501 is composed of a plurality of chain links 10, and two transverse chains 501 are provided. The transverse support 502 is installed and fixed on the outside of the chain link 10 inside the transverse chain 501, wherein the two transverse chains 501 divide the buffer chain 20 into three parts, and the part of the buffer chain 20 located between the two transverse chains 501 is smaller than the upper and lower parts of the buffer chain 20.

[0037] In the novel coal flow buffer device of the present invention, transverse links 501 are provided on the sides of multiple vertically arranged buffer links 20. These links 501 are mounted on the inner wall of the coal flow discharge bin 40 via metal mounting bases 503 and transverse supports 502. This allows for uniform assembly of multiple buffer links 20, ensuring contact area while enhancing the buffering effect. Furthermore, the range of motion of the multiple buffer links 20 is restricted, reducing the probability of the buffer links 20 colliding with the inner wall of the coal flow discharge bin 40.

[0038] Example 2

[0039] During actual operation, the present invention found that when the coal at the discharge port of the coal mine conveyor is buffered by the buffer chain 20 composed of multiple chain links 10, it is necessary to install a transverse chain 501 on the transverse part of the multiple buffer chains 20 to limit the position of the middle and bottom parts of the multiple buffer chains 20, so as to reduce the probability of the buffer chain 20 colliding with the inner wall of the coal flow unloading bin 40 when the buffer chain 20 collides with the coal mine. However, after the transverse chain 501 is actually connected to the buffer chain 20, the connection between the two is difficult to disassemble and maintain. At the same time, when the broken chain link 10 part of the buffer chain 20 needs to be replaced after long-term use, the chain link 10 part inside the buffer chain 20 is difficult to disassemble, and therefore the entire chain needs to be replaced, which is costly.

[0040] Specific reference Figure 11 and Figure 12 The chain link 10 is sequentially arranged from top to bottom into an upper semicircular metal ring 601, a connecting threaded rod 602 and a lower semicircular metal ring 603. The inner wall of the upper semicircular metal ring 601 is provided with an internal thread groove 604 matching the connecting threaded rod 602. The top of the lower semicircular metal ring 603 is rotatably connected to two movable thread blocks 60. The internal threads of the movable thread blocks 60 are connected to the connecting threaded rod 602. The connecting threaded rod 602 extends into the interior of the internal thread groove 604. The connecting threaded rod 602 is threadedly connected to the internal thread groove 604, and the outer side of the connecting threaded rod 602 is provided with a rubber sleeve installed between the upper semicircular metal ring 601 and the lower semicircular metal ring 603.

[0041] In the novel coal flow buffer device of the present invention, the adjustable internal diameter and detachable chain link 10 structure allow for simple and convenient replacement of one or more damaged chain links 10 by simply removing the corresponding chain link 10. This reduces time and costs, and eliminates the need to disassemble the entire buffer chain 20. Furthermore, by manually rotating the movable threaded block 60, which in turn rotates the connecting threaded rod 602, the threaded connection design ensures a more stable and secure connection between the upper semicircular metal ring 601, the lower semicircular metal ring 603, and the connecting threaded rod 602. This prevents the chain links 10 from being damaged or broken due to the impact of the coal flow, thereby extending the service life of the buffer chain 20 and the transverse chain 501 comprised of the chain links 10.

[0042] Without limitation, any person skilled in the art who is familiar with the technical field can make equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, and these changes should be covered by the protection scope of the present invention.
