Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.
[0035] In the description of the present application, it should be noted that the positions or location relationships indicated by the terms "inner", "outer" and the like are based on the positions or location relationships shown in the drawings, or the positions or location relationships commonly placed when the products of the present application are used, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the indicated devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0036] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0037] The anti-throwing buffer lifting assembly in the present application is mainly applied in the structure inside the chute in the coal preparation plant, and is mainly used for protecting the chute body and the lining plate. By setting the necessary impact buffer assembly, the potential energy in the throwing process is released in the form of impact and collision, and the mechanical impact of the throwing block on the chute body and the lining plate is offset.
[0038] Referring to Figure 1 , in combination with Figures 2-4 , the anti-throwing buffer lifting assembly in the present application is installed inside the chute 1 and receives the impact buffer of the throwing block 8 inside the chute 1.
[0039] The main structure of the anti-impact buffering and hoisting assembly comprises a vertically arranged buffering and hoisting plate 2, which is suspended and hoisted in the interior of the chute 1 through a hoisting chain 3, and is stably suspended by the self-weight of the buffering and hoisting plate 2. The chute 1 is connected with the upstream material conveying device 4 in a hinged manner, and is mainly used for the transfer of the material conveyed by the upstream material conveying device 4 in the conveying process of the material.
[0040] By arranging the vertically arranged buffering and hoisting plate 2 in the interior of the chute 1 and suspending and hoisting it in the interior of the chute 1 through the hoisting chain 3, the block material thrown by the upstream material conveying device 4 can impact on the buffering and hoisting plate 2, and the block material can be buffered during the impact, so that the impact energy of the block material can be greatly released.
[0041] On the one hand, the direct impact of the thrown block material 8 on the chute 1 can be avoided, and the impact of the thrown block material on the chute 1 during long-time operation can be prevented, so that the anti-impact effect can be effectively achieved. On the other hand, the buffering effect can also be achieved, the impact potential energy of the thrown block material 8 can be released during the impact, and after the impact potential energy is reduced, the block material can naturally fall from the buffering and hoisting plate 2. Compared with the direct falling form without the buffering and hoisting plate 2, the impact force on the chute 1 and the lining plate can be greatly reduced, and the chute 1 and the lining plate can be protected to the greatest extent.
[0042] By installing the buffering and hoisting plate 2 on the throwing track of the material conveyed by the upstream material conveying device 4, the conveying range of the thrown block material 8 can be effectively covered, and the impact of the thrown block material 8 can be borne.
[0043] By arranging the material blocking assembly 5 on the material receiving side of the buffering and hoisting plate 2, the thrown block material 8 can directly impact on the material blocking assembly 5, the direct impact on the material receiving surface of the buffering and hoisting plate 2 can be reduced, the shaking of the buffering and hoisting plate 2 can be reduced, and a certain amount of powder in the form of coal powder can be left on the material blocking assembly 5 after a period of operation, so that the thrown block material 8 can naturally fall after colliding with the left coal powder, and the buffering effect can be achieved.
[0044] The impact potential energy of the thrown block material 8 can be completely released during the impact, and the buffered block material can naturally fall below the buffering and hoisting plate 2, so that the impact and abrasion of the chute 1 and the lining plate can be reduced to the greatest extent.
[0045] In one specific embodiment, the buffering and hoisting plate 2 comprises a horizontally long and vertically short hoisting square plate, that is, the length direction of the buffering and hoisting plate 2 is horizontally arranged, and the width direction is vertically arranged, so that a larger throwing range can be covered in the horizontal direction, and the thrown block material 8 can fully impact on the hoisting plate.
[0046] The top edge of the hoisting square plate is uniformly provided with a plurality of hoisting holes 21 at the same interval, the hoisting chains 3 include a plurality of hoisting chains 3 extending into the chute 1, each hoisting chain 3 has the same length extending into the chute 1, and the bottom hoisting end of each hoisting chain 3 hoists the buffer hanging plate 2 through the hoisting hole 21 on the edge of the hoisting square plate.
[0047] In specific connection details, a closed hoisting ring 22 is connected on each hoisting hole 21, and the closed hoisting ring 22 is in a fixed closed connection with the hoisting hole 21.
[0048] Each hoisting chain 3 includes a terminal hoisting ring 31 at the bottom hoisting end, and an open connection ring 6 is arranged between the terminal hoisting ring 31 and the closed hoisting ring 22, and the hoisting chain 3, the buffer hanging plate 2 and the closed hoisting ring 22 are connected and disassembled through the open connection ring 6.
[0049] The open connection ring 6 in the embodiment is a mining open connection ring, which is simple and easy to obtain on site, is connected between the closed hoisting ring 22 and the terminal hoisting ring 31, and is fixed and closed by a bolt and a nut connected to the open connection ring 6. The nut is preferably a locking nut, which can avoid loosening in the impact vibration.
[0050] The chute 1 wall of the chute 1 is provided with a hoisting chain 3 through hole for connecting the hoisting chain 3, at least a part of the hoisting chain 3 is retained outside the chute 1, the hanging height position of the buffer hanging plate 2 in the chute 1 can be adjusted by adjusting the extension length of all the hoisting chains 3 in the chute 1, and the buffer hanging plate 2 can be conveniently relative to the trajectory position of the throwing block 8.
[0051] In order to avoid the influence of the opening on the structural strength of the chute 1, a reinforcing plate 11 is welded at the opening position of the hoisting chain 3 through hole on the chute 1 wall.
[0052] From the perspective of fixed suspension of the buffer hanging plate 2, a clamping pin 7 for connecting the hoisting chain 3 is arranged outside the chute 1, the clamping pin 7 includes a connecting cross rod 71 and a connecting handle 72, the connecting cross rod 71 passes through all the hoisting chains 3 and is clamped on the outer wall of the chute 1 wall, and the connecting handle 72 is convenient for clamping operation, so that the connecting cross rod 71 is connected in the form of a latch on the same corresponding hoisting chain 3 ring of all the hoisting chains 3, and the buffer hanging plate 2 is suspended in a horizontal form.
[0053] Although the material blocking assembly 5 can reduce the shaking of the buffer hanging plate 2, in order to avoid the collision of the buffer hanging plate 2 with the chute 1 wall in slight shaking, it is necessary to consider that the buffer hanging plate 2 is kept a certain distance from the vertical wall of the chute 1.
[0054] Specifically, the chute 1 wall in the utility model includes a transverse chute top wall 1a, a vertical chute side wall 1b and an inclined chute inclined wall 1c, the hanging chain 3 through hole is arranged on the chute inclined wall 1c, and the horizontal cross rod 71 is clamped on the outside of the chute inclined wall 1c, through the setting mode, the buffer hanging plate 2 can be hung in the middle part of the chute 1, even if shaking after being impacted by a large force, the chute 1 wall can be avoided from being impacted as much as possible.
[0055] It should be noted that when the chute 1 structure does not have a chute section, a hole can also be directly arranged on the chute top wall 1a, the buffer hanging plate 2 is hung below the chute top wall 1a and is as far away from the vertical wall of the chute 1 as possible, and the hanging position can also be adjusted according to the specific internal space; the overall purpose is to reduce the independent hanging of the buffer hanging plate 2 and reduce the interference between the buffer hanging plate 2 and other structures.
[0056] Referring to Figure 5 The anti-impact buffer hoisting assembly in the utility model is mainly applied in the lump coal conveying process of a coal preparation plant, and based on the fact that the material blocking assembly 5 can form a buffering effect to the accumulated coal powder to a certain extent, the material blocking assembly 5 includes a material blocking plate welded on the material receiving side wall of the buffer hanging plate 2, and the material blocking plate is vertically arranged relative to the material receiving side wall of the buffer hanging plate 2, that is, the plane where the material blocking plate is located is perpendicular to the plate surface of the buffer hanging plate 2.
[0057] The material blocking plate includes a plurality of material blocking vertical plates 51 and a material blocking horizontal plate 52 or a material blocking inclined plate 53 arranged between the material blocking vertical plates 51, and the material blocking horizontal plate 52 or the material blocking inclined plate 53 between adjacent material blocking vertical plates 51 is arranged in a staggered manner in the vertical direction. The material blocking vertical plate 51 is arranged vertically on the material receiving side wall of the buffer hanging plate 2 and has a certain width, and the length of the material blocking vertical plate 51 is slightly less than the height of the buffer hanging plate 2.
[0058] Further, the root of the material blocking horizontal plate 52 or the material blocking inclined plate 53 is fully welded to the buffer hanging plate 2 to avoid falling off from the buffer hanging plate 2 due to long-term impact and vibration.
[0059] The two ends of the material blocking horizontal plate 52 or the material blocking inclined plate 53 are respectively connected with the material blocking vertical plate 51, and in the processing and manufacturing process, the installation direction of the material blocking horizontal plate 52 is perpendicular to the installation direction of the material blocking vertical plate 51, and the material blocking inclined plate 53 is arranged obliquely relative to the material blocking vertical plate 51, and further, the material blocking horizontal plate 52 or the material blocking inclined plate 53 itself has a certain width, and there is no relative fixed angle between the material blocking inclined plate 53 and the material blocking vertical plate 51, which can form irregular material blocking compartments on the buffer hanging plate 2, and can satisfy the formation of the accumulated coal powder with a buffering effect in different states in the material blocking compartments after the coal blocks are impacted for a long time.
[0060] The anti-throwing and buffering hoisting assembly in the application is mainly used for receiving the block material conveyed by the upstream material conveying equipment 4 such as a conveying belt or a vibrating screen, so as to effectively intercept the thrown block material 8 by the buffering hoisting plate 2, and the width of the buffering hoisting plate 2 is not less than the width of the conveying belt or the width of the screen surface of the vibrating screen, so as to effectively cover the parabolic material conveying track of the thrown block material 8 and reliably protect the chute 1 body and the lining plate.

[0062] Generally, block material first impacts buffering hoisting plate 2 during falling and throwing process, effectively avoids direct collision with chute 1 and lining plate, reduces wear and tear of chute 1 and lining plate.
[0063] Buffering hoisting plate 2 is installed by hoisting chain 3, which can reduce the impact force of the material and facilitate the adjustment of the up-down position of the hoisting plate.
[0064] Hoisting chain 3 is inserted into the other clamping fixed outside the chute 1 through clamping pin 7, and the hoisting end of hoisting chain 3 is connected with closed hoisting ring 22 and buffering hoisting plate 2 through open connection ring 6, which facilitates installation and disassembly.
[0065] Material blocking assembly 5 welded on buffering hoisting plate 2 can store fine powder in the material blocking compartment formed by material blocking vertical plate 51, material blocking horizontal plate 52 or material blocking inclined plate 53 when block material impacts buffering hoisting plate 2, and the fine powder layer becomes a new protective layer, which can reduce noise and prolong the service life of buffering hoisting plate 2 when block material impacts the material protective layer.
[0066] Anti-throwing and buffering hoisting assembly can be pre-processed for standby, and can be quickly replaced when buffering hoisting plate 2 is severely worn.
