Description

Technical Field

[0001] This utility model relates to the field of bucket elevator technology, and in particular to a bucket elevator anti-blocking and chain breakage protection device. Background Technology

[0002] Bucket elevators are mechanical devices used to vertically or inclinedly lift bulk materials. They use a special fabric belt with many overlapping buckets to grab and lift the material from below to the top, and then automatically unload it after reaching the designated position. Bucket elevators are widely used in industries such as coal, building materials, grain, and chemicals.

[0003] The existing anti-blockage and chain breakage protection device in the hoist is located inside the hoist. When performing regular maintenance, the entire hoist needs to be disassembled for maintenance. The maintenance space is small, the lighting is poor, and the maintenance is inconvenient.

[0004] To address this issue, we propose a chain breakage protection device for bucket elevators to prevent blockages. Utility Model Content

[0005] The purpose of this utility model is to provide a bucket elevator anti-blocking and chain breakage protection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A bucket elevator anti-blocking and chain breakage protection device includes a box embedded in the elevator, a protection device is installed inside the box, and horizontal plates are slidably connected to the upper and lower sides of the box.

[0008] An ejection mechanism is used to eject the box body. The ejection mechanism includes two grooves respectively disposed in two horizontal plates. A slider is slidably connected in each of the two grooves. Both sliders are fixedly connected to the box body. A threaded rod is rotatably connected in each of the two grooves. The two threaded rods are respectively threaded through the two sliders. One end of each threaded rod rotatably passes through the horizontal plate and is connected to the transmission mechanism. A motor is fixedly connected to the side wall of one of the horizontal plates. The drive shaft of the motor rotatably passes through the horizontal plate and is fixedly connected to the threaded rod coaxially.

[0009] An ejection mechanism is used to eject the protective device of the housing. The ejection mechanism includes a mounting plate slidably connected to the inner side wall of the housing. A bidirectional threaded rod is rotatably connected inside the housing. Two threaded blocks are threaded on the external thread of the bidirectional threaded rod. Both threaded blocks are slidably connected to the inner side wall of the housing. A deflection plate is rotatably connected to the side wall of each threaded block. The end of each deflection plate away from the threaded block is rotatably connected to the mounting plate. The upper end of the bidirectional threaded rod rotatably extends through the housing into a groove and is coaxially fixedly connected to a gear. A rack is fixedly connected in the groove. The gear meshes with the rack. The slider has a slot that matches the rack.

[0010] Furthermore, the transmission mechanism includes two pulleys, which are coaxially and fixedly connected to two threaded rods, and the two pulleys are connected by a synchronous belt drive.

[0011] Furthermore, both threaded blocks are provided with threaded holes that match the bidirectional threaded rod, and the threads in the two threaded holes have opposite directions.

[0012] Furthermore, a door is hinged to the front end of the box.

[0013] Furthermore, both of the aforementioned horizontal plates are fixedly installed with the hoist.

[0014] Compared with the prior art, the beneficial effects of this utility model are at least as follows:

[0015] By setting up a push-out mechanism and a push-out mechanism, the motor drives two threaded rods to rotate, which in turn drive two sliders to move. The two sliders then move the housing, thus moving the housing to the outside of the hoist. Simultaneously, during the movement of the sliders, the rack drives the gear to rotate, which in turn drives the double-threaded rod to rotate. The double-threaded rod then drives the two threaded blocks to move relative to each other. The two threaded blocks, through two deflection plates, drive the mounting plate to move until they reach the appropriate position. This allows the anti-blocking chain breakage protection device to be moved out of the housing. During maintenance, there is ample space and good lighting, making maintenance relatively convenient.

[0016] This utility model provides ample space and good lighting for the maintenance of the anti-blocking and chain breakage protection device, making maintenance relatively convenient. Attached Figure Description

[0023] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0024] Please see Figures 1 to 5 A bucket elevator anti-blocking and chain breakage protection device includes a box 1 embedded in the elevator. It is worth mentioning that the front end of the box 1 is hinged with a box door 17, a protection device is installed inside the box 1, and horizontal plates 2 are slidably connected to the upper and lower sides of the box 1. It should be noted that both horizontal plates 2 are fixedly installed with the elevator.

[0025] To facilitate maintenance of the anti-blocking chain breakage protection device, it needs to be moved outside the hoist. Therefore, an ejection mechanism 3 is set up to eject the box 1. The ejection mechanism 3 includes two grooves 4 respectively set in two horizontal plates 2. Sliding blocks 5 are slidably connected in both grooves 4. Both sliding blocks 5 are fixedly connected to the box 1. Threaded rods 6 are rotatably connected in both grooves 4. The two threaded rods 6 are threaded through the two sliding blocks 5 respectively. One end of the two threaded rods 6 rotatably passes through the horizontal plate 2 and is connected by a transmission mechanism 7. Specifically, the transmission mechanism 7 includes two pulleys 16. The two pulleys 16 are coaxially fixedly connected to the two threaded rods 6 respectively. The two pulleys 16 are connected by a synchronous belt. A motor 8 is fixedly connected to the side wall of one of the horizontal plates 2. The drive shaft of the motor 8 rotatably passes through the horizontal plate 2 and is coaxially fixedly connected to the threaded rods 6.

[0026] Through the above-mentioned technical features, the motor 8 drives the two threaded rods 6 to rotate, the two threaded rods 6 drive the two sliders 5 to move, and the two sliders 5 drive the box 1 to move, so that the box 1 can be moved to the outside of the hoist for easy maintenance.

[0027] To facilitate maintenance of the protective devices inside the housing 1 and improve lighting during maintenance, an ejection mechanism 9 is provided to eject the protective devices from the housing 1. The ejection mechanism 9 includes a mounting plate 10 that is slidably connected to the inner wall of the housing 1. A bidirectional threaded rod 18 is rotatably connected inside the housing 1. Two threaded blocks 11 are threaded on the outer thread of the bidirectional threaded rod 18. It should be noted that both threaded blocks 11 have threaded holes that match the bidirectional threaded rod 18. The threads in the two threaded holes have opposite directions. Both threaded blocks 11 are slidably connected to the inner wall of the housing 1. A deflection plate 12 is rotatably connected to the side wall of both threaded blocks 11. The ends of the two deflection plates 12 away from the threaded blocks 11 are rotatably connected to the mounting plate 10. The upper end of the bidirectional threaded rod 18 rotatably extends through the housing 1 into the groove 4 and is coaxially fixedly connected to a gear 13. A rack 14 is fixedly connected in the groove 4. The gear 13 and the rack 14 are meshed. The slider 5 has a slot 15 that matches the rack 14.

[0028] Through the above technical features, during the movement of the slider 5, the rack 14 drives the gear 13 to rotate, the gear 13 drives the bidirectional threaded rod 18 to rotate, the bidirectional threaded rod 18 drives the two threaded blocks 11 to move relative to each other, and the two threaded blocks 11 drive the mounting plate 10 to move through the two deflection plates 12 until the appropriate position is reached, so that the protection device can be moved out of the box. When maintaining it, there is a wide space and good lighting.

[0029] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
