Description

Technical Field

[0001] The utility model relates to the field of heavy hammer buffer devices, in particular to a heavy hammer buffer device for a belt conveyor. Background Technique

[0002] At present, belt conveyors are widely used in various industries such as metallurgy, construction, coal, chemical industry, and transportation at home and abroad. The vertical heavy hammer tensioning device of a belt conveyor is the most commonly used tensioning method in the belt conveyor industry for heavy hammer buffer devices of belt conveyors. During the long-term operation of the belt conveyor, the heavy hammer box is likely to fall to the ground due to the action of its gravity without any precaution, causing damage to the equipment and even casualties to nearby personnel.

[0003] Chinese Patent with the related publication number CN104003115B discloses a heavy hammer buffer device for a belt conveyor, including two horizontally arranged transverse brackets, and two parallel vertical brackets vertically arranged in the middle positions of the two transverse brackets. Both ends of the two transverse brackets are arranged on the support rods. There are four support rods. A strong compression spring is sleeved on the lower part of the support rod. The strong compression spring is located between the first mounting base and the second mounting base. The bottom end of the support rod passes through the second mounting base and is fixed to the first mounting base with the strong compression spring. The upper end of the support rod is provided with a thread, and the transverse bracket is fixed to the second mounting base through a hexagonal nut and a gasket. Four rubber buffer seats are oppositely arranged on the two parallel vertical brackets, and the four rubber buffer seats are fixed by bolts and nuts.

[0004] In view of the above related technologies, when the strong compression spring sleeved on the lower part of the support rod is compressed, the height of the corresponding support rod will be reduced. When the impact on the buffer device is uneven during the falling and offset of the heavy hammer, it is very easy for the heavy hammer to slide to one side due to fewer support points of the buffer device, there are certain safety hazards. To sum up, the existing heavy hammer buffer device for a belt conveyor is not easy to stably receive the impact of the heavy hammer. Content of the Utility Model

[0005] Based on this, the purpose of the present utility model is to provide a heavy hammer buffer device for a belt conveyor to solve the technical problem that the existing heavy hammer buffer device for a belt conveyor is not easy to stably receive the impact of the heavy hammer.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: A heavy hammer buffer device for a belt conveyor, including a bottom plate and a top plate. A plurality of groups of springs are evenly spaced and connected between the bottom plate and the top plate. The bottom plate and the top plate are parallel to each other, and guiding structures that are slidably matched are arranged facing each other at the edges. The edges of the bottom plate and the top plate protrude, and connecting bolts for restricting the bottom plate and the top plate from moving away from each other pass through the protruding positions.

[0007] By adopting the above technical solution, the enclosing plate structures arranged facing each other between the plates play a guiding role in the up-and-down sliding of the plates, and the springs evenly arranged between the plates can also achieve a good buffering effect when the heavy hammer falls eccentrically, effectively avoiding the deviation of the heavy hammer during the fall.

[0008] The present utility model is further configured such that a lower enclosing plate facing upward is connected to the edge of the bottom plate, an upper enclosing plate facing downward is connected to the edge of the top plate, and the upper enclosing plate is slidably connected within the lower enclosing plate.

[0009] By adopting the above technical solution, the enclosing plate structure between the bottom plate and the top plate can well limit the sliding between the top plate and the bottom plate.

[0011] By adopting the above technical solution, the connecting bolt between the bottom plate connecting ear and the top plate connecting ear can also play a certain guiding role when the top plate is impacted.

[0012] The present utility model is further configured such that when the connecting bolt restricts the bottom plate and the top plate from moving away from each other, the bottom surface of the upper enclosing plate is lower than the top surface of the lower enclosing plate.

[0013] By adopting the above technical solution, the upper enclosing plate can smoothly slide within the lower enclosing plate.

[0014] The present utility model is further configured such that the bottom plate connecting ear is parallel to the bottom plate and contacts the lower enclosing plate, and the top plate connecting ear is parallel to the top plate and contacts the upper enclosing plate.

[0015] By adopting the above technical solution, the bottom plate connecting ear is simultaneously welded to the bottom plate and the lower enclosing plate, improving the stability of the bottom plate connecting ear.

[0016] The present utility model is further configured such that a first damping plate is connected to the bottom surface of the bottom plate, and a second damping plate is connected to the top surface of the top plate.

[0017] By adopting the above technical solution, the damping plate structures connected to the bottom plate and the top plate can play a further buffering role.

[0018] The present utility model is further configured such that when the connecting bolt connects the top plate connecting ear and the bottom plate connecting ear, the spring is in a compressed state.

[0019] By adopting the above technical solution, a tendency for the top plate and the bottom plate to move away from each other is maintained, thereby effectively improving the stability of the top plate.

[0020] In summary, the utility model mainly has the following beneficial effects:

[0021] 1. In the utility model, spring structures for buffering are evenly spaced between two parallel plates.

[0029] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0030] The embodiments of the present utility model will be described below according to its overall structure.

[0031] Embodiment 1

[0032] A heavy hammer buffer device for a belt conveyor, as Figures 1-5As shown, it includes a bottom plate 1 and a top plate 2. Specifically, both the top plate 2 and the bottom plate 1 can be arranged in the direction of the weight falling. Both the top plate 2 and the bottom plate 1 are flat steel plates. A plurality of groups of springs 10 are evenly spaced and connected between the bottom plate 1 and the top plate 2. Specifically, the relative spacing between the springs 10 does not exceed the diameter of the springs 10 themselves. While ensuring that there are enough springs 10 to absorb the impact of the weight, the mutual contact between the springs 10 can also play a certain role in preventing the weight from skewing and slipping. The bottom plate 1 and the top plate 2 are parallel to each other, and guiding structures with sliding fits are arranged facing each other at the edges. The edges of the bottom plate 1 and the top plate 2 protrude, and connecting bolts 7 for restricting the bottom plate 1 and the top plate 2 from moving away from each other pass through at the protruding positions.

[0033] Please refer to Figures 1-5 , the bottom plate connecting ear 5 is parallel to the bottom plate 1 and contacts the lower enclosing plate 8. The top plate connecting ear 6 is parallel to the top plate 2 and contacts the upper enclosing plate 9. The bottom plate connecting ear 5 is welded to both the bottom plate 1 and the lower enclosing plate 8. While improving the stability of the bottom plate connecting ear 5, it also has an effect of strengthening the anti-deformation of the lower enclosing plate 8. The top plate connecting ear 6 is welded to both the top plate 2 and the upper enclosing plate 9. While improving the stability of the top plate connecting ear 6, it also has an effect of strengthening the anti-deformation of the upper enclosing plate 9.

[0034] Please refer to Figures 2-5 , the edge of the bottom plate 1 is connected with a downward-facing lower enclosing plate 8, and the edge of the top plate 2 is connected with an upward-facing upper enclosing plate 9. The upper enclosing plate 9 is slidably connected inside the lower enclosing plate 8. The enclosing plate structure between the bottom plate 1 and the top plate 2 can well restrict the sliding between the top plate 2 and the bottom plate 1. When the top plate 2 is subjected to an off-center impact, it can make the springs 10 maintain a vertically compressed state as much as possible, thereby effectively preventing the weight from slipping to one side of the buffer device. When the connecting bolt 7 connects the top plate connecting ear 6 and the bottom plate connecting ear 5, the springs 10 are in a compressed state, making the top plate 2 and the bottom plate 1 have a tendency to move away from each other, thereby effectively improving the stability of the top plate 2 and preventing the top plate 2 from shaking. At the same time, when the top plate 2 is subjected to a downward impact, it can prevent the weight from shifting and slipping due to the excessive compression stroke of the springs 10.

[0035] Please refer to Figures 3-5, a plurality of bottom plate connecting ears 5 are fixedly connected to the edge of the bottom plate 1, and a plurality of top plate connecting ears 6 corresponding to the bottom plate connecting ears 5 are fixedly connected to the edge of the top plate 2. A connecting bolt 7 passes through between the top plate connecting ear 6 and the bottom plate connecting ear 5. The connecting bolt 7 between the bottom plate connecting ear 5 and the top plate connecting ear 6 can also play a certain guiding role when the top plate 2 is impacted. The position of the nut on the connecting bolt 7 can be adjusted by rotation to adjust the distance between the top plate 2 and the bottom plate 1. The connecting bolt 7 can also play a leveling role, making the top plate 2 and the bottom plate 1 keep relatively parallel. When the connecting bolt 7 restricts the bottom plate 1 and the top plate 2 from moving away from each other, the bottom surface of the upper enclosure plate 9 is lower than the top surface of the lower enclosure plate 8, so that the upper enclosure plate 9 can slide smoothly in the lower enclosure plate 8 and avoid the upper enclosure plate 9 sliding and separating from the lower enclosure plate 8.

[0036] Embodiment 2

[0037] A heavy hammer buffer device for a belt conveyor, as Figures 1-5 shown. On the basis of Embodiment 1, the difference from Embodiment 1 is that a first damping plate 3 is connected to the bottom surface of the bottom plate 1, and a second damping plate 4 is connected to the top surface of the top plate 2. The damping plate structures connected to the bottom plate 1 and the top plate 2 can play a further buffering role, and the elastic deformation of the damping plate material is used to further improve the buffering efficiency for the heavy hammer, so that the buffer device can buffer the heavy hammer more effectively. Specifically, the first damping plate 3 and the second damping plate 4 can be connected to the bottom plate 1 and the top plate 2 respectively by bonding or screw connection. In this embodiment, the damping plate structure specifically adopts the bonding connection method.

[0038] The working principle of the present utility model is as follows: The heavy hammer falls on the second damping plate 4 above the top plate 2. The second damping plate 4 deforms first to absorb part of the impact force of the heavy hammer. Then the heavy hammer continues to fall, the spring 10 is compressed, the upper enclosure plate 9 slides downward in the lower enclosure plate 8, and at the same time, the connecting bolt 7 between the top plate 2 and the bottom plate 1 also plays a guiding role, enabling the heavy hammer to fall vertically and compress the spring 10, effectively preventing the heavy hammer from sliding to one side of the buffer device when it falls eccentrically.

[0039] Although the embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model, and they are not limitations of the utility model. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations that do not make creative contributions to the embodiments according to needs, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
