Description

Technical Field

[0001] This utility model relates to the field of bucket elevator technology, specifically to a device for detecting whether the bucket elevator is operating normally. Background Technology

[0002] Bucket elevators are commonly used material conveying equipment in industrial production, widely applied in mining, metallurgy, and building materials industries. They use chains or belts to drive the buckets in a cyclical motion, achieving vertical lifting and conveying of materials through the significant drop between the loading and unloading points. During operation, the material supply at the loading port and the presence of debris blocking the unloading port directly affect the stable operation of the equipment.

[0003] In some existing bucket elevators, the conveying mechanism of the feeding section will generate inherent vibration during normal operation, but the vibration is limited to the feeding area. The discharge port is usually located above the feeding port, with a large height difference between the two. The discharge port is often separated by a floor slab as a discharge platform. At the same time, the discharge port is often connected to the subsequent belt conveyor to form a semi-enclosed transmission channel, which causes the feeding section to vibrate, but the discharge section itself will not generate obvious vibration.

[0004] When the feeding port is clogged with too much material or impurities, the internal conveying mechanism will jam, causing the feeding section to stop vibrating. At this time, the staff at the feeding platform cannot directly observe the feeding section to determine whether the equipment is operating normally. They need to open the observation window of the feeding port to observe whether the equipment is operating normally. However, opening the observation window when there is material at the feeding port is even more dangerous. Therefore, if the feeding port is blocked, the staff at the feeding platform will not be able to detect the problem in time, resulting in the equipment not being repaired in time, affecting the material transportation efficiency, and in severe cases, it may lead to equipment damage. Utility Model Content

[0005] In view of this, the present invention provides a device for detecting whether the bucket elevator is operating normally. It can observe whether the equipment is operating normally from the unloading platform. If a blockage occurs, the staff can discover it in time and repair the equipment to avoid affecting the material transportation efficiency and prevent the equipment from being damaged.

[0006] To solve the above-mentioned technical problems, this utility model provides a device for detecting whether a bucket elevator is operating normally. The device includes a bucket elevator, a base on a vibrating part of the bucket elevator, and a counterweight box fixed to one side of the feed inlet. The base is welded to the counterweight box. When the bucket elevator is operating normally, the counterweight box can drive the base to vibrate continuously. It also includes a metal rod, the lower end of which is connected to the base, and the other end extending vertically upwards to one side of the discharge section. When the operator is on the operating platform at the discharge inlet, the upper end of the rod can be seen with the naked eye. When the bucket elevator is operating normally, allowing material to be transported normally through its internal conveying system, the counterweight box on the feed inlet side can vibrate. Vibration can be transmitted through the base to the rod, and the overall vibration of the rod can be transmitted to the upper end, allowing the operator at the feeding port to judge whether the bucket elevator is operating normally by observing the vibration of the rod. When the bucket elevator is operating normally, the upper end of the rod will vibrate. If the internal conveying system of the bucket elevator stops operating, the feeding port and counterweight box of the bucket elevator will stop vibrating, causing the upper end of the rod to also stop vibrating. Thus, through the design of the rod, the operator at the feeding port operating platform can still judge whether the bucket elevator is operating normally. If the feeding port is blocked, the operator can find it in time and repair the equipment to avoid affecting the material transportation efficiency and prevent equipment damage.

[0007] The boom is detachably mounted on the base, which facilitates disassembly of the boom for subsequent maintenance of the bucket elevator.

[0008] The base surface has vertically formed mounting holes; the lower end of the rod is inserted into the mounting holes, with the mounting holes and the cross-section of the rod having a clearance fit, and a through-hole is formed on the circumferential surface of the lower end of the rod; on the lower surface of the base, two fixing blocks are symmetrically arranged on both sides of the mounting holes, and a connecting hole is coaxially formed at the center of the two fixing blocks; when the lower end of the rod is inserted into the mounting holes, a portion of the lower end of the rod can pass through the mounting holes and extend to the bottom of the base, and the through-hole and the connecting hole are located on the same central axis, and a fixing rod is also included. At this point, insert the fixing rod sequentially into the connecting hole and the insertion hole. Then, tighten the fixing nuts on the bolts at both ends of the fixing rod, so that the nuts are tightly against the side wall of the fixing block. By tightening the two nuts, the fixing rod and the fixing block are fixed together, thereby fixing the rod body and fixing the rod body to the base. When it is necessary to disassemble the rod body, remove the two nuts from the bolts at both ends of the fixing rod, and then pull the fixing rod out of the connecting hole and the insertion hole, thereby removing the fixing of the rod body. Then the rod body can be pulled out of the mounting hole and disassembled.

[0009] A guide block is provided on one side wall of the outer casing at the feed inlet of the bucket elevator. The guide block has a guide hole, and the rod is inserted into the guide hole. The inner diameter of the guide hole is larger than the outer diameter of the rod, so that there is a large gap between the inner wall of the guide hole and the circumferential surface of the rod. The guide block can support the upper part of the rod, and the gap can control the amplitude of the radial swing of the rod, preventing the rod from tilting due to excessive vibration amplitude and improving the service life of the rod.

[0010] The upper end of the rod is equipped with a conspicuous marker. When the operator is on the operating platform at the material discharge port, the conspicuous marker at the upper end of the rod can be seen with the naked eye. The color of the conspicuous marker contrasts with the background color of the working environment, and the conspicuous marker can vibrate synchronously with the rod to enhance the intuitiveness of the vibration state observation and make it easier for the operator to observe the state of the rod more clearly.

[0011] The eye-catching signage is an item with high-contrast colors, specifically a reflective cloth strip. The reflective cloth strip is composed of bright yellow fabric and reflective strips bonded together. The reflective cloth strip is attached to the upper end of the pole using adhesive tape, which is commonly used in existing technologies. The reflective cloth strip can sway synchronously with the vibration of the pole. The combination of the bright yellow fabric and reflective strips at the upper end of the pole enhances the intuitiveness of observing the vibration state when the lighting conditions change.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0013] 1. When using this utility model, the equipment can be observed from the unloading platform to see if it is operating normally. If a blockage occurs, the staff can promptly discover and repair the equipment to avoid affecting the material transportation efficiency and prevent damage to the equipment.

[0014] 2. When this utility model is used, the dynamic gap design between the guide mechanism and the rod not only suppresses structural fatigue caused by large swings, but also fully preserves the vibration transmission characteristics, prevents the rod from tilting, and improves the service life of the device.

[0015] 3. When using this utility model, the detachable design of the rod and the base makes it easy to remove the rod for maintenance and inspection of the bucket elevator.

[0016] 4. When using this utility model, the conspicuous markings on the rod body can enhance the intuitiveness of observing the vibration state under changing lighting conditions. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0026] A device for detecting whether a bucket elevator is operating normally, such as Figure 1-5 As shown: The bucket elevator 100 is included. The internal transport system of the bucket elevator 100 adopts a V-belt drive. The vibrating part of the bucket elevator 100 is equipped with a base 400. The vibrating part is a counterweight box 300 fixed on one side of the feed port (the counterweight box 300 is used to balance the center of the bucket elevator 100. It is existing technology and its internal structure will not be described in detail here). The base 400 is welded to the counterweight box 300. When the bucket elevator 100 is running normally, the counterweight box 300 can drive the base 400 to vibrate continuously.

[0027] It also includes a metal rod 200, the lower end of which is connected to the base 400, and the other end of which extends vertically upward to one side of the unloading section 101, so that the rod 200 is parallel to the bucket elevator 100 in the height direction. When the operator is on the operating platform where the unloading section 101 is located, the upper end of the rod 200 can be seen with the naked eye.

[0028] When the bucket elevator 100 is operating normally, transporting materials through its internal conveying system, the counterweight box 300 on one side of its feed inlet vibrates. This vibration is transmitted through the base 400 to the rod 200, and the overall vibration of the rod 200 is transmitted to its upper end. This allows operators on the operating platform at the feed inlet to observe the vibration of the rod 200 to determine if the bucket elevator 100 is operating normally. Normal vibration at the upper end of the rod 200 indicates normal operation of the bucket elevator 100. If the upper end of the rod 200 stops vibrating, it indicates that the bucket elevator 100 is not operating normally. If the internal transport system stops operating, the control switch of the bucket elevator 100 can be observed to determine whether the discharge port is blocked by material. If the discharge port is blocked by material or debris, the operating system of the bucket elevator 100 can be shut down in time, and the bucket elevator 100 can be repaired. Through the setting of the rod 200, the staff at the discharge port operation platform can still determine whether the bucket elevator 100 is operating normally. If the discharge port is blocked, the staff can find it in time and repair the equipment to avoid affecting the material transport efficiency and prevent equipment damage.

[0029] Specifically, the rod 200 is detachably mounted on the base 400. This detachable mounting facilitates the removal of the rod 200 for subsequent maintenance of the bucket elevator 100.

[0030] Specifically, mounting holes 401 are vertically formed on the surface of the base 400;

[0031] The lower end of the rod 200 is inserted into the mounting hole 401, and the mounting hole 401 is in clearance fit with the cross section of the rod 200, and the insertion hole 202 is opened through the circumferential surface of the lower end of the rod 200.

[0032] On the lower surface of the base 400, two fixing blocks 500 are symmetrically provided on both sides of the mounting hole 401, and the center of the two fixing blocks 500 is coaxially provided with a connecting hole 501;

[0033] When the lower end of the rod 200 is inserted into the mounting hole 401, a portion of the lower end of the rod 200 can pass through the mounting hole 401 and extend below the base 400. The rod 200 is axially rotated to adjust the insertion hole 202 on its circumferential surface to be coaxial with the connecting hole 501. A fixing rod 600 is also included. The fixing rod 600 is sequentially inserted through the connecting hole 501 and the insertion hole 202, allowing the fixing rod 600 to cooperate with the fixing block 500 to support the rod 200. The fixing rod 600 has external threaded sections at both ends, specifically two threads welded to the two axial end faces of the fixing rod 600. The bolts have external threads that are screwed onto nuts 601, which are then tightened against the side wall of the fixing block 500. By screwing on the two nuts 601, the fixing rod 600 is fixed to the fixing block 500, thereby fixing the rod body 200 and fixing it to the base 400. When it is necessary to disassemble the rod body 200, the two nuts 601 are removed from the bolts at both ends of the fixing rod 600. Then, the fixing rod 600 is pulled out from the connecting hole 501 and the insertion hole 202, thereby releasing the fixation of the rod body 200. The rod body 200 can then be pulled out from the mounting hole 401 and disassembled.

[0034] It is worth mentioning that the lower part of the base 400 is provided with a triangular reinforcing rib, which is fixed to the side wall of the counterweight box 300, thereby improving the stability of the fixed connection between the base 400 and the counterweight box 300.

[0035] according to Figure 1 and Figure 6 As shown, specifically, a guide block 700 is provided on one side wall of the outer casing at the discharge port of the bucket elevator 100. The guide block 700 has a guide hole 701, and the rod 200 is inserted into the guide hole 701. The inner diameter of the guide hole 701 is larger than the outer diameter of the rod 200, so that there is a large gap between the inner wall of the guide hole 701 and the circumferential surface of the rod 200. The design of the guide block 700 can support the upper part of the rod 200, and the gap can control the radial swing amplitude of the rod 200, preventing the rod 200 from tilting due to excessive vibration amplitude, and improving the service life of the rod 200.

[0036] The upper end of the rod 200 is provided with a conspicuous identification piece 201. When the operator is on the operating platform at the unloading part 101, the conspicuous identification piece 201 at the upper end of the rod 200 can be seen with the naked eye. The color of the conspicuous identification piece 201 contrasts with the background color of the working environment, and the conspicuous identification piece 201 can vibrate synchronously with the rod 200 to enhance the intuitiveness of the vibration state observation and make it easier for the operator to observe the state of the rod 200 more clearly.

[0037] Specifically, the conspicuous marker 201 is an item with high-contrast colors, which can be colored lights or brightly colored fabric. Specifically, it is a reflective strip, composed of bright yellow fabric and a reflective strip bonded together. The reflective strip is attached to the upper end of the pole 200 using adhesive tape, which is commonly used in existing technologies. The reflective strip can sway synchronously with the vibration of the pole 200. The combination of the bright yellow fabric and the reflective strip at the upper end of the pole 200 enhances the intuitiveness of observing the vibration state under changing lighting conditions.

[0038] It should be clarified that this utility model relates to a bucket elevator and is mainly used to observe whether the bucket elevator is operating normally. It should be noted that the bucket elevator, the feeding and unloading parts of the bucket elevator, and the counterweight box are all existing equipment. Since they are not the main technical features of this utility model, the model will not be limited here, nor will its structure be described in detail. Only the usage method and installation position of the rod and the base will be described in detail.

[0039] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
