Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a buffer protection component for a lifting bucket of an elevator. Background Art

[0002] Bucket elevators, also known as bucket elevators, are a common type of vertical or inclined conveying and lifting equipment, primarily used to lift materials from low to high locations. In the brick-making industry, the bucket elevator receives materials such as gravel, pebbles, and sand from the conveyor belt. After the materials enter the bucket, they are automatically and continuously transported upwards by the elevator's lifting mechanism.

[0003] The current technical problem is that due to the height between the conveyor belt and the hopper, the gravel generates gravitational potential energy, which will impact the elevator bucket after falling into it. Over time, potholes will appear on the surface of the elevator bucket, reducing its service life. In order to reduce the potential energy, the current method in this field can only be to reduce the height difference between the conveyor belt and the elevator bucket, but this greatly limits the use of the elevator, and therefore cannot completely solve this problem.

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below 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, rather than all the embodiments.

[0032] See also Figure 1-5 The utility model provides a technical solution: a buffer protection assembly for a lifting bucket of an elevator, comprising: a shell 1 with a feed port 2 and a discharge port 3; a first buffer assembly provided in the shell 1, the first buffer assembly being used to initially reduce the falling potential energy of the material entering the shell 1, the first buffer assembly comprising a buffer plate 5, the upper end of the buffer plate 5 forming an inclined surface for catching the material; a second buffer assembly provided in the shell 1 and close to the lower end of the inclined surface of the buffer plate 5, the second buffer assembly being used to perform a secondary potential energy reduction on the material that falls onto the inclined surface and bounces up;

[0033] The above technical solution is used to provide buffer protection for the housing 1 during feeding. When in use, the feed port 2 is connected to the feeding end of the conveyor belt, such as Figure 5 As shown, under normal circumstances, stones and gravel are stored in the silo on the left, and sand is stored in the silo on the right. When the sand falls into the shell 1, it will not cause significant damage to it. Therefore, it is generally not necessary to set a first buffer assembly on the right side of the shell 1. During operation, the silo on the left puts down the gravel material and drops it into the upper end of the conveyor belt. The conveyor belt sends the material into the lifting bucket. When the gravel falls on the inclined surface of the buffer plate 5, it will bounce up and hit the second buffer assembly. When it overcomes the bearing capacity of the second buffer assembly and rolls down along the buffer plate 5, the falling potential energy is reduced. At this time, the gravel will not cause a significant impact on the shell 1, thereby protecting the lifting bucket. Subsequently, the sand is released from the silo on the right and sent into the shell 1 through the conveyor belt. The gravel and sand in the shell 1 are sent to the mixing equipment through the lifting mechanism for mixing and stirring, thereby manufacturing the base material of the brick.

[0034] It is worth mentioning that the buffer plate 5 is tilted to produce an inclined surface in order to ensure that the gravel can be ejected onto the second buffer component. If the buffer plate 5 is set horizontally, when the gravel falls onto the upper surface of the buffer plate 5, the ejection trajectory of the gravel is difficult to contact the second buffer component, and it cannot play a stable role in reducing the falling potential energy.

[0035] like Figure 1 As shown, in this embodiment, the first buffer assembly includes: a rotating body 4 with an end shaft, the end shaft is rotatably matched with a rotating groove provided in the inner wall of the housing 1, and the rotating body 4 is connected to the buffer plate 5; a buffer structure for buffering the buffer plate 5 after being subjected to force;

[0036] like Figure 1 and Figure 4 As shown, in this embodiment, the buffer structure includes at least one buffer portion, which includes: a shock absorber 6 and a first hinge seat 7 movably connected to one end of the shock absorber 6, the first hinge seat 7 is connected to the inner wall of the shell 1, and the other end of the shock absorber 6 is movably connected to a second hinge seat 8, and the second hinge seat 8 is connected to the bottom of the rotating body 4;

[0037] The above technical solution can achieve initial shock absorption of the material through the buffer plate 5. When the gravel falls onto the buffer plate 5, it will form downward pressure on the buffer plate 5, forcing the buffer plate 5 to rotate around the end axis of the rotating body 4, thereby generating elastic pressure on the shock absorber 6. The shock absorber 6 dampens and buffers the elastic pressure, thereby initially reducing the falling potential energy of the gravel.

[0038] like Figure 3As shown, in this embodiment, the rotating body 4 and the buffer plate 5 are detachably connected; specifically, a mounting hole 9 is formed at the bottom of the rotating body 4, a first threaded hole 10 is formed in the area where the buffer plate 5 and the rotating body 4 are in contact, and a first fixing bolt 11 is provided between the mounting hole 9 and the first threaded hole 10;

[0039] The above technical solution can facilitate the removal of the buffer plate 5 from the rotating body 4. Since the buffer plate 5 often needs to catch fallen gravel, the buffer plate 5 will be worn more and needs regular replacement and maintenance. When disassembling, use a screwdriver to unscrew the first fixing bolt 11 so that the first fixing bolt 11 is disengaged from the mounting hole 9 and the first threaded hole 10, and the buffer plate 5 can be removed from the rotating body 4, which is very convenient.

[0040] Further, such as Figure 3 As shown, in this embodiment, a positioning rod 12 is provided at one end of the rotating body 4, and the positioning rod 12 is plugged into and pulled out of a positioning groove 13 provided in the buffer plate 5;

[0041] The above technical solution can facilitate the installation of the buffer plate 5. During installation, the positioning rod 12 at one end of the rotating body 4 is aligned with the positioning groove 13 in the buffer plate 5 and inserted until it reaches the maximum position. The positioning is then completed. Then, the first fixing bolt 11 is screwed into the mounting hole 9 and the first threaded hole 10 to complete the fixing of the rotating body 4 and the buffer plate 5. The installation is more convenient.

[0042] like Figure 3 As shown, in this embodiment, a cavity 14 is formed at the upper end of the rotating body 4, and the cavity 14 is consistent with the thickness of the buffer plate 5;

[0043] The above technical solution can make the upper end surfaces of the rotating body 4 and the buffer plate 5 flush, which is conducive to guiding the gravel to fall and preventing the gravel from getting stuck.

[0044] like Figure 1 As shown, in this embodiment, the second buffer assembly includes: a fixed splint 15 and a chain 17 with one end fixed to the fixed splint 15, and the other end of the chain 17 droops under the action of gravity to form a free end;

[0045] The above technical solution is used to reduce the falling potential energy of the gravel for a second time. When the gravel falls on the inclined surface of the buffer plate 5, it will bounce up and hit the chain 17. When it overcomes the bearing capacity of the chain 17 and rolls down along the buffer plate 5, the falling potential energy is reduced. At this time, the gravel will not cause a large impact on the shell 1, thereby protecting the lifting bucket.

[0046] like Figure 2As shown, in this embodiment, the second buffer assembly further includes: a positioning pin 16 provided on one side of the fixed clamping plate 15, the positioning pin 16 being used to be inserted into the through hole of the chain 17; a movable clamping plate 18 having a pin hole 19, the pin hole 19 cooperating with the positioning pin 16, and a clamping space for clamping the chain 17 is formed between the movable clamping plate 18 and the fixed clamping plate 15; a second fixing bolt 21, which cooperates with a second threaded hole 20 provided on the surface of the positioning pin 16;

[0047] The above technical solution can facilitate the disassembly and installation of the chain 17. When the chain 17 needs to be replaced, use a screwdriver to unscrew the second fixing bolt 21 on the surface of the positioning pin 16, and then pull the pin hole 19 of the movable splint 18 out of the positioning pin 16. The movable splint 18 can be removed from the fixed splint 15, so that the chain 17 can be removed from the positioning pin 16, which is very convenient.

[0048] like Figure 1 and Figure 4 As shown, in this embodiment, a sealing block 22 is provided on the inner wall of the housing 1, and a movable groove is provided in the area where the sealing block 22 is in contact with the rotating body 4;

[0049] The above technical solution can prevent gravel from entering the gap between the shell 1 and the rotating body 4, prevent the rotation of the rotating body 4 from being affected, and improve the stability of the structure.

[0050] Working principle: When in use, first connect the feed port 2 to the feed end of the conveyor belt, such as Figure 5 As shown, under normal circumstances, stones and gravel are stored in the silo on the left, and sand is stored in the silo on the right. When the sand falls into the shell 1, it will not cause significant damage to it. Therefore, it is generally not necessary to set a first buffer assembly on the right side of the shell 1. During operation, the gravel material is dropped from the silo on the left and falls into the upper end of the conveyor belt. The conveyor belt feeds the material into the lifting bucket. When the gravel falls onto the inclined surface of the buffer plate 5, it will bounce up. At the same time, the gravel will force the buffer plate 5 to rotate around the end axis of the rotating body 4, thereby generating elastic pressure on the shock absorber 6. The shock absorber 6 absorbs and buffers the elastic pressure, thereby reducing the falling potential energy of the gravel for the first time. The bounced gravel hits the chain 17, overcomes the bearing capacity of the chain 17 and rolls down along the buffer plate 5. The falling potential energy is reduced. At this time, the gravel will not cause a large impact on the shell 1, thereby protecting the lifting bucket. Then the sand is released from the right hopper and sent into the shell 1 through the conveyor belt. The gravel and sand in the shell 1 are sent to the mixing equipment through the lifting mechanism for mixing and stirring, thereby making the base material of the brick.
