Description

Technical Field

[0001] The present invention relates to the technical field of conveying buffering, in particular to a buffer bed of a belt conveyor. Background Art

[0002] The buffer bed of a belt conveyor is an important auxiliary equipment. It is installed below the material loading point (such as the drop port) to withstand the impact force of the falling material. It is mainly used to reduce the impact of the material on the conveyor belt, protect the conveyor belt and rollers, thereby increasing the life of the equipment and optimizing operating efficiency. The existing buffer bed is mainly composed of a support frame, a support frame and buffer strips. The buffer strips are fixed to the support frame by bolts, and the support frame is then fixed to the support frame by bolts.

[0003] However, the following problems currently exist in the assembly and use of the impact bed: the impact rubber strips and the support frame need to be fixed by multiple bolts, and the installation requires repeated alignment, pre-tightening of the bolts, and final tightening. The overall operation is cumbersome and time-consuming. At the same time, it is difficult to ensure that the tightening firmness of the bolts in the corresponding positions is consistent, and a large number of bolts need to be removed for maintenance or replacement of the rubber strips, which is time-consuming and labor-intensive. Secondly, the existing impact bed is only cushioned by impact rubber strips, and the overall cushioning effect needs to be improved.

[0004] Therefore, the problems of cumbersome assembly and disassembly of the impact bed, inconsistent tightening of bolts, and poor impact effect are technical problems that need to be solved by those skilled in the art. Summary of the Invention

[0005] In view of the above problems, an embodiment of the present invention provides a buffer bed for a belt conveyor to solve the above-mentioned technical problems.

When the support frame drives the T-block forward, the front and rear ends of the limiting column respectively pass through the positioning plate and the connecting block to preliminarily fix the support frame on the fixed plate. A locking part for locking the moved support frame is provided on the support assembly.

[0009] As a preferred solution, the limiting portion includes a disc, and discs are fixedly installed at the upper and lower ends of the buffer spring. The lower end of the lower disc is fixedly connected to the upper end of the connecting block, and the upper disc is detachably installed on the buffer rubber strip.

[0010] As a preferred solution, the support assembly includes two channel steels that are symmetrical in front and back and have openings facing each other. A base plate is fixedly installed on the upper ends of the two channel steels.

The upper end surface of the support plate is an inclined surface inclined from top to bottom toward the middle of the base plate. The inclined surfaces of the support plates arranged in the front and back and on the same side are fixedly connected to the corresponding fixed plates.

[0011] As a preferred solution, the support assembly further includes an L-shaped support fixedly mounted in the middle of the base plate, and the upper ends of the vertical sections of the L-shaped supports of the multiple support assemblies are fixedly connected to the fixed plate in the middle.

[0012] As a preferred solution, the support plate and the base plate are jointly provided with an adjusting member for adjusting the angle of the support plate; the adjusting member includes an arc-shaped groove, and the support plate is provided with an arc-shaped groove concentric with the corresponding shaft column. A support seat is fixedly installed on the base plate, and a bolt is threadedly connected to the support seat. After the bolt slides through the arc-shaped groove, a nut is installed, and the support plate is fixed to the support seat by the combination of the bolt and the nut.

[0013] As a preferred solution, the locking part includes a pushing plate, and a pushing plate corresponding to the fixed plate and located on the rear side of the corresponding T-block is provided between two adjacent support assemblies. Two guide shafts that slide through the corresponding positioning plate and the support plate are fixedly installed at the front end of the left and right pushing plates, and two guide shafts that slide through the corresponding positioning plate and the vertical section of the L-shaped support are fixedly installed at the front end of the middle pushing plate.

[0014] As a preferred solution, the positioning plate is fixedly installed at the lower end of the corresponding fixed plate and is located on the front side of the corresponding T-block. The limiting column slides back and forth through the vertical section of the corresponding T-block. A convex ring is provided on the limiting column, and a compression spring is installed between the rear end of the convex ring and the T-block.

[0015] As a preferred solution, the pushing plate is provided with a fixing part for fixing the pushing plate after the mobile pushing T-block; the fixing part includes a fixing rod, and a fixing rod is fixedly installed between the pushing plates corresponding to the same fixed plate, and the front end of the fixing rod slides through all the positioning plates and support plates or L-shaped supports and is fixed to the corresponding support plate or L-shaped support through nut 2.

[0016] As a preferred solution, the locking piece includes a card plate, and a circular groove corresponding to the buffer spring is opened at the upper end of the buffer rubber strip, and a through groove is opened through the bottom wall of the circular groove of the buffer rubber strip. The upper end of the upper disc is fixed with a card plate by a support. After the card plate passes through the corresponding through groove from top to bottom, it is rotated ninety degrees to be perpendicular to the through groove and the upper disc is tightly attached to the lower end face of the buffer rubber strip to limit the card plate from moving into the through groove.

[0017] As a preferred solution, a positioning column that slides through the corresponding positioning plate is fixedly installed at the front end of the T-block.

[0019] 2. The present invention adopts a synergistic energy absorption design of the buffer spring and the buffer rubber strip, and uses the compression and rebound characteristics of the buffer spring to dynamically disperse the impact energy, reduce the local stress concentration of the buffer rubber strip, reduce the risk of plastic deformation or cracking, and at the same time improve the buffering effect of the buffer bed.

[0020] 3. The buffer rubber strip provided in the present invention is quickly connected with the buffer spring through the rotation of the clamping plate, and is quickly assembled by driving the insertion of the limit column through the movement of the T-block.

[0032] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] like Figure 1 As shown, a buffer bed of a belt conveyor includes a plurality of support assemblies 4 distributed front to back, and three fixed plates 1 arranged from left to right are commonly provided on the support assemblies 4. The middle fixed plate 1 is horizontally arranged on the support assembly 4, and the fixed plates 1 on both sides are inclined in an inverted eight shape on the support assembly 4, and a buffer mechanism 2 is provided on the fixed plate 1.

[0034] like Figure 1 、 Figure 2 and Figure 3 As shown, the buffer mechanism 2 includes a support frame 20, and the upper end of the fixed plate 1 is evenly provided with a concave support frame 20 from left to right, and a T-block 21 fixedly installed at the lower end of the support frame 20 is provided between two adjacent support components 4. A waist-shaped groove that slides in a one-to-one correspondence with the T-block 21 is opened on the fixed plate 1, and a buffer rubber strip 22 is slidably installed in the support frame 20. A buffer spring 23 corresponding to the T-block 21 is detachably installed between the buffer rubber strip 22 and the support frame 20, and a limiting portion 3 is commonly provided on the fixed plate 1 and the T-block 21.

[0035] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the limiting portion 3 includes a locking piece and a connecting block 30 for fixing the buffer spring 23, and the buffer spring 23 is provided with a connecting block 30 that slides through the T-block 21, and a positioning plate 31 corresponding to the fixed plate 1 is provided between two adjacent support assemblies 4, and a section of the T-block 21 perpendicular to the corresponding support frame 20 (that is, the vertical section of the T-block 21) is located between the corresponding connecting block 30 and the positioning plate 31, and a limiting column 32 is slidably installed on the T-block 21. In the process of the support frame 20 driving the T-block 21 to move forward, the front and rear ends of the limiting column 32 respectively pass through the positioning plate 31 and the connecting block 30; the support assembly 4 is provided with a locking portion 5 for fixing the moved support frame 20.

[0036] During the specific work, the buffer spring 23 is manually installed on the buffer rubber strip 22 first, and then the buffer rubber strip 22 is installed in the support frame 20, and the connecting block 30 slides through the support frame 20 and the T-block 21. Then, the support frame 20 installed with the buffer rubber strip 22 is installed on the corresponding fixed plate 1 in turn, and the connecting block 30 and the T-block 21 pass through the waist-shaped groove. Then, the support frame 20 is moved forward so that the front and rear ends of the limit column 32 pass through the positioning plate 31 and the connecting block 30 respectively, and then the support frame 20 installed with the buffer rubber strip 22 and moved forward is fixed by the locking part 5, thereby realizing the rapid assembly of the buffer bed.

[0037] like Figure 2 and Figure 5As shown, the limiting portion 3 includes a disc 33, and the upper and lower ends of the buffer spring 23 are fixedly mounted with discs 33. The lower end of the lower disc 33 is fixedly connected to the upper end of the connecting block 30, and the upper disc 33 is detachably mounted on the buffer rubber strip 22.

[0038] like Figure 2 and Figure 6 As shown, the locking piece includes a card plate 34, a circular groove corresponding to the buffer spring 23 is opened at the upper end of the buffer rubber strip 22, and a through groove 220 is opened through the bottom wall of the circular groove of the buffer rubber strip 22. The card plate 34 is fixedly installed on the upper end of the upper disc 33 through a pillar. After the card plate 34 passes through the corresponding through groove 220 from bottom to top, it is rotated ninety degrees and is perpendicular to the through groove 220. The upper disc 33 is close to the lower end surface of the buffer rubber strip 22, limiting the card plate 34 from moving into the through groove 220.

[0039] like Figure 1 、 Figure 2 and Figure 3 As shown, the support assembly 4 includes two front-to-back symmetrical channel steels 40 with openings facing each other, a bottom plate 41 is fixedly installed on the upper ends of the two channel steels 40, a rectangular groove is opened in the middle of the bottom plate 41 and is connected to the gap between the two channel steels 40, and two left-right symmetrical support plates 42 are rotatably installed between the two channel steels 40 through an axial column, and the upper end surface of the support plate 42 is an inclined surface inclined from top to bottom toward the middle of the bottom plate 41, and the inclined surfaces of the support plates 42 arranged front to back and on the same side are fixedly connected to the corresponding fixed plate 1, and the support plate 42 and the bottom plate 41 are jointly provided with an adjustment member 44 for adjusting the angle of the support plate 42.

[0040] like Figure 1 、 Figure 2 and Figure 3 As shown, the support assembly 4 also includes an L-shaped support 43 fixedly installed in the middle of the base plate 41, and the upper ends of the vertical sections of the L-shaped supports 43 of multiple support assemblies 4 are fixedly connected to the central fixed plate 1.

[0041] like Figure 2 and Figure 3 As shown, the adjusting member 44 includes an arc groove 440, and the support plate 42 is provided with an arc groove 440 concentric with the corresponding shaft column. A support seat is fixedly installed on the base plate 41, and a bolt 441 is threadedly connected to the support seat. The bolt 441 slides through the arc groove 440 and is then installed with a nut 1. The support plate 42 is fixed to the support seat by the bolt 441 and the nut 1.

[0042] like Figure 2 、 Figure 3 、 Figure 6 and Figure 7As shown, during specific operation, loosen nut 1, then rotate the support plate 42, and the bolt 441 slides in the arc groove 440 to adjust the inclination angle of the inclined surface on the support plate 42 to adapt to different types of materials. The small angle is suitable for large or sticky materials, mainly reducing the risk of blockage and friction of the buffer strip 22; the medium angle is suitable for conventional bulk materials, balancing the centering of the material and the impact dispersion; the large angle is for high-speed or fine-grained materials, enhancing the conveyor belt guidance and anti-spill control effects. After adjusting the support plate 42 to the appropriate angle, manually tighten the nut to fix the support plate 42 tightly to the support seat. After the fixation is completed, manually pass the clamping plate 34 through the corresponding through slot 220 from bottom to top, and then rotate the clamping plate 34 ninety degrees so that the clamping plate 34 and the through slot 220 are perpendicular to each other, and the clamping plate 34 is in contact with the inner wall of the circular groove, and the upper disc 33 is close to the lower end face of the buffer strip 22, thereby achieving the installation of the buffer spring 23 on the buffer strip 22. After the installation is completed, the buffer strip 22 with the buffer spring 23 installed is installed on the support frame 20, and the connecting block 30 is passed through the support frame 20 and the T-block 21 to limit the buffer strip 22.

[0043] When the buffer rubber strip 22 needs to be replaced, release the fixing of the locking part 5 on the support frame 20 and separate the limit column 32 from the positioning plate 31, then manually move the buffer rubber strip 22 out of the support frame 20, and separate the connecting block 30 from the T-block 21 and the support frame 20, then rotate the upper disc 33 ninety degrees, and the disc 33 drives the clamping plate 34 to rotate ninety degrees through the support and become parallel to the through slot 220. At this time, the clamping plate 34 can be moved downward through the through slot 220 to separate from the buffer rubber strip 22, and then the buffer rubber strip 22 can be replaced, and then repeat the above installation operation to install the replaced buffer rubber strip 22 on the support frame 20.

[0044] like Figure 1 、 Figure 2 and Figure 3 As shown, the locking portion 5 includes a pushing plate 50, and a pushing plate 50 corresponding to the fixed plate 1 and located on the rear side of the corresponding T-block 21 is provided between two adjacent support assemblies 4. The front ends of the left and right pushing plates 50 are fixedly installed with two guide shafts 51 that slide through the corresponding positioning plates 31 and the support plates 42. The front end of the middle pushing plate 50 is fixedly installed with two guide shafts 51 that slide through the corresponding positioning plates 31 and the vertical section of the L-shaped support 43. A fixing part 52 is provided on the pushing plate 50 for fixing the pushing plate 50 after the mobile pushing T-block 21.

[0045] like Figure 1 、 Figure 2 and Figure 3As shown, the fixing member 52 includes a fixing rod 520, and a fixing rod 520 is fixedly installed between the pushing plates 50 corresponding to the same fixing plate 1. The front end of the fixing rod 520 slides through all the positioning plates 31 and the support plates 42 or L-shaped supports 43 and is fixed to the corresponding support plates 42 or L-shaped supports 43 through nut 2.

[0046] like Figure 3 、 Figure 4 and Figure 5 As shown, the positioning plate 31 is fixedly installed at the lower end of the corresponding fixing plate 1 and is located in front of the corresponding T-block 21. The limiting column 32 slides back and forth through the vertical section of the corresponding T-block 21. A convex ring 320 is provided on the limiting column 32. A compression spring 321 is installed between the rear end of the convex ring 320 and the T-block 21 and is sleeved on the limiting column 32. The front end of the T-block 21 is fixedly installed with a positioning column 210 that slides through the corresponding positioning plate 31.

[0047] When the support frame 20 is fully installed on the corresponding fixed plate 1, the pushing plate 50 is manually moved forward, and the pushing plate 50 drives the fixing rod 520 to move along the guide shaft 51. After the pushing plate 50 contacts the T-block 21, it pushes the corresponding T-block 21 so that the T-block 21 drives the corresponding support frame 20 to move forward. The forward movement of the T-block 21 also drives the limiting column 32 to move forward, and the front end of the limiting column 32 passes through the corresponding positioning plate 31, limiting the T-block 21 from separating from the fixed plate 1. When the convex After the ring 320 contacts the positioning plate 31, the T-block 21 continues to move forward. Since the convex ring 320 contacts the positioning plate 31, the limiting column 32 cannot move further, so that the T-block 21 will compress the compression spring 321 and continue to move forward, so that the rear end of the limiting column 32 passes through the connecting block 30, so that the connecting block 30 and the T-block 21 are bidirectionally interlocked. At this time, the front end of the fixing rod 520 passes through the corresponding support plate 42 or L-shaped support 43, and then the moved fixing rod 520 is fixed to the support plate 42 or L-shaped support 43 by nut 2.

[0048] When the buffer rubber strip 22 needs to be replaced due to wear or other reasons, first remove the nut 2, then move the pushing plate 50 backward to make the pushing plate 50 away from the corresponding T-block 21, and then move the support frame 20 of the buffer rubber strip 22 that needs to be replaced backward. The support frame 20 drives the corresponding limiting column 32 to move through the corresponding T-block 21, and under the action of the compression spring 321, the convex ring 320 first maintains contact with the positioning plate 31 until the limiting column 32 is completely separated from the connecting block 30, at which time the compression spring 321 returns to its original state, and then as the support frame 20 moves, the convex ring 320 is released. As the frame 20 continues to move backward, the T-block 21 and the compression spring 321 drive the convex ring 320 to separate from the positioning plate 31, and then the buffer strip 22 is moved to separate from the support frame 20. The buffer strip 22 also drives the buffer spring 23 and the connecting block 30 to separate from the support frame 20, and then the clamping plate 34 is rotated ninety degrees to be parallel to the through groove 220. At this time, the buffer strip 22 can be removed and replaced, and then the buffer strip 22 can be installed on the support frame 20 according to the above operation, and then the support frame 20 with the buffer strip 22 installed is installed on the fixed plate 1 and fixed.
