Description

Technical Field

[0001] The utility model relates to the field of bucket elevators, and in particular to a bucket elevator protection device. Background Art

[0002] A bucket elevator is a device that transports materials vertically or at an angle. It uses a chain or belt equipped with a bucket to lift the material to a certain height, and then unloads the material to the target location through gravity. As a commonly used large-scale vertical transportation and lifting equipment, bucket elevators are widely used in production.

[0003] Currently, bucket elevators can experience sway during vertical material transport due to uneven material distribution, excessive weight of the material being hoisted, vibration of the platform motor, and high-altitude winds. This sway not only affects the normal operation of the equipment but can also lead to safety hazards such as top equipment falling. Bucket elevators with drive platforms located above the roof are particularly susceptible to high-altitude winds. Under the influence of high-altitude winds, the bucket elevator swings significantly, which can cause the drive equipment to fall, posing a safety hazard. Utility Model Content

[0004] The purpose of the utility model is to provide a bucket elevator protection device. The bucket elevator protection device is arranged at a position close to a high driving platform and has a protection frame. The swing amplitude of the bucket elevator can be limited by the protection frame.

[0005] In order to achieve the above-mentioned object, the utility model provides a bucket elevator protection device, which includes a support platform, a protection frame and a column for supporting the protection frame, wherein the lower end of the column is fixedly connected to the support platform, and the upper end of the column is fixedly connected to the protection frame;

[0006] The protection frame is arranged perpendicular to the length direction of the bucket elevator, and the distance between the protection frame and the driving platform of the bucket elevator is set to 500-800 mm;

[0007] The protection frame coincides with the center line of the bucket elevator, and the distance between the inner edge of the protection frame and the outer edge of the bucket elevator is set to 100-150 mm.

[0008] Preferably, a first embedded plate is provided on the surface where the support platform is connected to the column. The first embedded plate is provided in a one-to-one correspondence with the column, and the column is fixedly connected to the corresponding first embedded plate.

[0009] Preferably, the columns are screwed to the corresponding first embedded plates.

[0010] Preferably, the support platform is provided with a protruding support beam, the support beam is fixedly connected to the column, and the support beam is used to support the column.

[0011] Preferably, the support platform is provided with a second embedded plate, and the support beam is fixedly connected to the second embedded plate.

[0012] Preferably, a buffer mechanism is provided on the inner edge of the protection frame, and the buffer mechanism is arranged facing the bucket elevator.

[0013] Preferably, the buffer mechanism includes a buffer spring and a limit rod, the length direction of the limit rod is perpendicular to the length direction of the bucket elevator, one end of the buffer spring is fixedly connected to the limit rod, and the other end is fixedly connected to the protective frame.

[0014] Preferably, the buffer springs are symmetrically arranged along the center line of the bucket elevator.

[0015] Preferably, the length of the limiting rod is not less than the width of the corresponding bucket elevator.

[0016] According to the above technical solution, the present invention supports the uprights through the support platform, allowing the protection frame to be close to the bucket elevator's drive platform. Because the bucket elevator is stabilized by its bottom being fixed to the ground, the swing amplitude of the drive platform at the highest point will be greater than the swing amplitude at other locations of the bucket elevator. Therefore, when the protection is placed closer to the drive platform, the protection frame can more effectively limit the bucket elevator's swing amplitude, preventing the bucket elevator from shaking further.

[0017] The protection frame is set perpendicular to the length direction of the bucket elevator, and the distance between the protection frame and the driving platform of the bucket elevator is set to 500-800mm. Therefore, the protection frame is located less than 1m away from the driving platform, so that the swing amplitude of the bucket elevator at the position of the protection frame is close to the swing amplitude of the driving platform. That is, by setting the distance between the protection frame and the bucket elevator, the swing amplitude of the driving platform can be effectively limited.

[0018] The distance between the inner edge of the protective frame and the outer edge of the bucket elevator is set to 100-150mm, that is, the bucket elevator has a swing margin of ±100-150mm in both the X and Y directions. Setting this margin to no more than 150mm can limit the overall swing amplitude of the bucket elevator, especially the swing amplitude of the drive platform is also limited to within ±100-150mm.

[0019] Setting the margin to be no less than 100mm can effectively avoid frequent operation of the protection. If the margin is set to less than 100mm, the chance of collision between the bucket elevator and the bucket elevator protection device will be greatly increased. Frequent collisions by the bucket elevator may affect the service life of the bucket elevator protection device. Similarly, frequent collisions between the bucket elevator and the bucket elevator protection device will also affect the service life of the bucket elevator.

[0020] Therefore, the distance between the inner edge of the protection frame and the outer edge of the bucket elevator is set to 100-150mm, so that the bucket elevator protection device will only limit the bucket elevator when the swing amplitude of the driving platform is greater than 100mm. Moreover, through the limiting effect of the protection frame, the maximum swing amplitude of the bucket elevator is no more than 150mm, which can meet the needs of actual production and effectively avoid safety problems.

[0021] Other features and advantages of the present invention will be described in detail in the subsequent detailed description of the embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0036] In the present utility model, unless otherwise specified, directional words such as "lower end, upper end, vertical, inner edge" contained in the term only represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0037] See also Figure 1-5 The bucket elevator protection device comprises a support platform 1, a protection frame 2 and a column 3 for supporting the protection frame 2, wherein the lower end of the column 3 is fixedly connected to the support platform 1, and the upper end of the column 3 is fixedly connected to the protection frame 2;

[0038] The protection frame 2 is arranged perpendicular to the length direction of the bucket elevator 10, and the distance between the protection frame 2 and the driving platform 101 of the bucket elevator 10 is set to 500-800mm;

[0039] The protection frame 2 coincides with the center line of the bucket elevator 10 , and the distance between the inner edge of the protection frame 2 and the outer edge of the bucket elevator 10 is set to 100-150 mm.

[0040] By implementing the above technical solution, the support of the support platform 1 on the column 3 allows the protection frame 2 to be close to the drive platform 101 of the bucket elevator 10. Since the bucket elevator 10 is fixed to the ground at its bottom to obtain stable support, the swing amplitude of the drive platform 101 at the highest point will be greater than the swing amplitude of other positions of the bucket elevator 10. Therefore, when the protection frame 2 is placed closer to the drive platform 101, the protection frame 2 can more effectively limit the swing amplitude of the bucket elevator 10, preventing the bucket elevator 10 from shaking further.

[0041] The protection frame 2 is arranged perpendicular to the length direction of the bucket elevator 10, and the distance between the protection frame 2 and the driving platform 101 of the bucket elevator 10 is set to 500-800 mm. Therefore, the protection frame 2 is located less than 1 m away from the driving platform 101, so that the swing amplitude of the bucket elevator 10 at the position of the protection frame 2 is close to the swing amplitude of the driving platform 101. That is, by setting the distance between the protection frame 2 and the bucket elevator 10, the swing amplitude of the driving platform 101 can be effectively limited.

[0042] The distance between the inner edge of the protective frame 2 and the outer edge of the bucket elevator 10 is set to 100-150 mm, that is, the bucket elevator 10 has a swing margin of ±100-150 mm in both the X and Y directions. Setting this margin to no more than 150 mm can limit the overall swing amplitude of the bucket elevator 10, especially the swing amplitude of the drive platform 101 is also limited within ±100-150 mm.

[0043] Setting the margin to be no less than 100mm can effectively avoid frequent operation of the protection frame 2. If the margin is set to less than 100mm, the chance of collision between the bucket elevator 10 and the bucket elevator protection device will be greatly increased. Frequent collisions by the bucket elevator 10 may affect the service life of the bucket elevator protection device. Similarly, frequent collisions between the bucket elevator 10 and the bucket elevator protection device will also affect the service life of the bucket elevator 10.

[0044] Therefore, the distance between the inner edge of the protective frame 2 and the outer edge of the bucket elevator 10 is set to 100-150mm, so that the bucket elevator protection device will only limit the bucket elevator 10 when the swing amplitude of the driving platform 101 is greater than 100mm. Moreover, through the limiting effect of the protective frame 2, the maximum swing amplitude of the bucket elevator 10 is no more than 150mm, which can meet the needs of actual production and effectively avoid safety problems.

[0045] Preferably, a guardrail 5 is provided on the passage from the support platform 1 to the columns 3 to prevent people from approaching the spaces between the columns 3 where there is a risk of falling.

[0046] In this embodiment, preferably, the surface where the support platform 1 is connected to the column 3 is provided with a first embedded plate 11, the first embedded plate 11 is provided in one-to-one correspondence with the column 3, and the column 3 is fixedly connected to the corresponding first embedded plate 11.

[0047] The support platform 1 usually uses the existing concrete platform of the factory building, and the first embedded plate 11 is constructed simultaneously during the concrete construction process, so that after the concrete platform construction is completed, the column 3 can be reliably connected to the first embedded plate 11 to achieve reliable support for the protective frame 2.

[0048] In one embodiment, the column 3 is welded to the first embedded plate 11, and the connection between the column 3 and the first embedded plate 11 is achieved by welding. When using this embodiment, the height of the column 3 should not be too high, and the load on the protection frame 2 should not be too large, otherwise there will be a risk of tearing the weld.

[0049] Preferably, in order to ensure the reliability and stability of the bucket elevator protection device structure, the bucket elevator protection device further includes an oblique support 6, each end of which is provided with a connector 61, and the connector 61 is connected to the column 3 and the protection frame 2 respectively. Generally, welding can be used to weld the two mutually perpendicular sides of the connector 61 to the column 3 and the protection frame 2, thereby achieving the fixation of the oblique support 6 between two adjacent columns 3. The use of the oblique support 6 can effectively improve the stability of the support of the column 3 on the protection frame 2, and can also achieve balanced force between multiple columns 3, which can protect the column 3 and the weld between the column 3 and the first embedded plate 11.

[0050] In this embodiment, preferably, the column 3 is screwed to the corresponding first embedded plate 11 .

[0051] In another embodiment, bolts matching the columns 3 are also embedded together with the first embedded plate 11 , and the columns 3 and the first embedded plate 11 are connected by bolts.

[0052] Specifically, the lower end of the column 3 is connected to a connecting plate, which is provided with through holes that cooperate with bolts. The column 3 and the first embedded plate 11 are reliably connected by screwing the connecting plate and the first embedded plate 11.

[0053] In this embodiment, preferably, the support platform 1 is provided with a protruding support beam, the support beam is fixedly connected to the column 3, and the support beam is used to support the column 3.

[0054] If the factory building does not have a concrete platform of suitable height, the support for the column 3 can also be achieved by connecting the support beam to the column or wall of the factory building.

[0055] In this embodiment, preferably, the support platform 1 is provided with a second embedded plate 12 , and the support beam is fixedly connected to the second embedded plate 12 .

[0056] A second embedded plate 12 is pre-embedded at a position of the wall or column facing the support beam, and is connected to the wall or column of the factory building through the second embedded plate 12. The support beam can be fixedly connected to the second embedded plate 12 by welding or screwing.

[0057] In this embodiment, preferably, a buffer mechanism is provided on the inner edge of the protection frame 2 , and the buffer mechanism is provided facing the bucket elevator 10 .

[0058] In order to reduce the impact force generated when the protection frame 2 collides with the bucket elevator 10, a buffer mechanism can be provided on the inner edge of the protection frame 2. When the bucket elevator 10 swings to a position close to the protection frame 2, it will first hit the buffer mechanism. After the buffering effect of the buffer mechanism, the impact force of the bucket elevator 10 hitting the protection frame 2 will be greatly reduced, thereby achieving the protection effect of the bucket elevator protection device and the bucket elevator 10.

[0059] In this embodiment, preferably, the buffer mechanism includes a buffer spring 41 and a limit rod 42, the length direction of the limit rod 42 is perpendicular to the length direction of the bucket elevator 10, one end of the buffer spring 41 is fixedly connected to the limit rod 42, and the other end is fixedly connected to the protective frame 2.

[0060] The buffer spring 41 will be compressed and deformed during the collision process, and the deformation of the buffer spring 41 absorbs the energy of the collision, thereby achieving the purpose of reducing the impact force.

[0061] The limiting rod 42 has a certain length, which can easily capture the supporting column of the bucket elevator 10, thereby preventing the column of the bucket elevator 10 from passing over the buffer spring 41 and directly hitting the protection frame 2 during a collision.

[0062] In one embodiment, the buffer spring 41 can be welded to the protective frame 2 at one end and to the limiting rod 42 at the other end, thereby realizing the connection between the buffer mechanism and the protective frame 2. However, when adopting this method, the protective frame 2 is fixed by the buffer spring 41, and the reliability is very poor. Moreover, since the buffer spring 41 is prone to deformation, the actual position of the protective frame 2 may not match the ideal position.

[0063] In another embodiment, the protective frame 2 is provided with a through hole, the limiting rod 42 is provided with a guide rod that cooperates with the through hole, and the buffer spring 41 is sleeved on the guide rod. At least two guide rods are provided, and multiple guide rods can cooperate with the through hole to achieve reliable support for the protective frame 2. Moreover, the guide rods can slide freely within the through hole. Therefore, when a collision occurs, the buffer spring 41 can still absorb the collision energy through deformation, thereby achieving a buffering effect.

[0064] Preferably, a protrusion is provided at one end of the guide rod away from the protection frame 2 to prevent the guide rod from falling out of the through hole on the protection frame 2 .

[0065] In this embodiment, preferably, the buffer springs 41 are symmetrically arranged along the center line of the bucket elevator 10 .

[0066] The buffer springs 41 are symmetrically arranged along the center line of the bucket elevator 10, so that the multiple buffer springs 41 can evenly withstand the force of the collision, so that after the collision occurs, the limit rod 42 can be as close to the protection frame 2 as possible in a posture parallel to the protection frame 2.

[0067] In this embodiment, preferably, the length of the limiting rod 42 is not less than the width of the corresponding bucket elevator 10 .

[0068] In the process of the bucket elevator 10 approaching the protective frame, the longer limit rod 42 can more effectively encounter the bucket elevator 10 in advance, and when the length of the limit rod 42 is not less than the width of the corresponding bucket elevator 10, it can reliably prevent the swinging bucket elevator 10 from approaching the protective frame 2.

[0069] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.

[0070] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0071] In addition, the various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
