Abstract
Description
Technical Field
[0001] This utility model relates to the field of online maintenance technology for bucket elevators, specifically a device that facilitates online maintenance of bucket elevators. Background Technology
[0002] A bucket elevator is a machine that continuously and vertically transports materials through buckets fixed to a traction component. It is mainly used for the vertical lifting of powdery, granular, and small lump materials (such as coal, cement, ore, etc.), and the conveying height can reach more than 40 meters. The core components include a traction component (ring chain, plate chain, or belt), buckets, drive unit, and sealed housing.
[0003] Bucket elevators rely on double chains to drive buckets for material transport, but their overall height is significant, increasing the length of the internal sprockets. During long-term operation, the chain drive efficiency is difficult to maintain consistently, and lubrication conditions are prone to fluctuations. To ensure normal chain operation, manual monitoring and lubrication replenishment are necessary periodically. However, due to the chain length, timely monitoring and replenishment of lubrication points are difficult—workers must check each point through inspection ports, a process that is not only inefficient but also lacks real-time accuracy. This often leads to accelerated wear in areas lacking lubrication due to delayed replenishment. Furthermore, manual lubrication has significant drawbacks: excessive lubrication can drip onto the ground, causing pollution; insufficient lubrication fails to meet lubrication needs, making it difficult to improve overall lubrication efficiency.
[0004] The flue gas desulfurization system in the boiler of the gas-fired generator set uses a bucket elevator. As the operating time increases, the bucket elevator will gradually show some faults, such as belt misalignment, scraper wear, and ash block jamming, which will affect the normal operation of the desulfurization system and may even lead to certain environmental risks. At this time, the generator set and the desulfurization system need to be shut down for treatment. Unplanned shutdowns will lead to problems such as gas venting and reduced power generation.
[0005] Therefore, this utility model provides a device that facilitates online maintenance of bucket elevators to solve the above-mentioned problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Embodiment 1:
[0026] Please see Figure 1-5 A device for facilitating online maintenance of a bucket elevator includes an outer shell 1. An oil replenishment component 11 is provided inside the outer shell 1. The oil replenishment component 11 includes an oil storage box 1101 fixedly connected to the inner side of the outer shell 1. A feeding pipe 1102 is provided on the side of the oil storage box 1101. The side of the feeding pipe 1102 extends into the oil storage box 1101. The side of the oil storage box 1101 extends into the outer shell 1. A fixing plate 1105 is fixedly connected to the side of the oil storage box 1101. A conveying pump 1103 is fixedly installed on the side of the oil storage box 1101. A connecting pipe 1104 is provided at the inlet of the conveying pump 1103. One end of the connecting pipe 1104 extends into the oil storage box 1101. The other end of the connecting pipe 1104 is fixedly connected to the inlet of the conveying pump 1103. A conveying pipe 1106 is provided at the outlet of the conveying pump 1103.
[0027] One end of the delivery pipe 1106 is fixedly connected to the outlet of the delivery pump 1103, and the other end of the delivery pipe 1106 is fixedly connected to the oil outlet pipe 1107. The oil outlet pipe 1107 passes through the fixing plate 1105 and is fixedly connected to the fixing plate 1105. An oil outlet hole 1108 is opened on the outside of the oil outlet pipe 1107, and a sponge cylinder 1109 is fixedly connected to the outside of the oil outlet pipe 1107.
[0028] In this embodiment, during operation, the delivery pump 1103 draws lubricating oil from the oil storage box 1101 and delivers it to the oil outlet pipe 1107 through the connecting pipe 1104 and the delivery pipe 1106. An oil outlet hole 1108 on the outside of the oil outlet pipe 1107 allows lubricating oil to seep out. The oil outlet hole 1108 is only opened in the direction corresponding to the chain 8. The lubricating oil seeps from the oil outlet hole 1108 into the sponge sleeve 1109, and is then applied to the outside of the chain 8 through the sponge sleeve 1109, achieving a lubricating effect on the chain 8. Two oil outlet pipes 1107 are configured as a group, wrapping around the outside of the chain 8 to ensure sufficient lubrication of the chain 8. In addition to lubrication, when there is too much lubricating oil, the sponge sleeve 1109 can also be used to absorb the lubricating oil to prevent it from dripping due to excessive oil injection. The oil replenishment component 11 enables automatic oil replenishment of the chain 8, which can effectively reduce downtime and allow the device to lubricate the chain 8 without stopping the machine, ensuring that the chain 8 can be lubricated in a timely manner without manual operation, saving manpower and resources, and improving the application effect of lubricating oil. The delivery pump 1103 is controlled by the PLC controller 2 to control the oil output and prevent excessive or insufficient oil injection.
[0029] Example 2:
[0030] Please see Figure 2-7 This embodiment provides a technical solution based on embodiment one: a monitoring component 10 is provided above the oil replenishment component 11. The monitoring component 10 includes a mounting base 1001 that is embedded and fixedly connected to the inside of the housing 1. A receiver 1002 is fixedly connected to the side of the mounting base 1001. The receiver 1002 and the delivery pump 1103 are electrically connected.
[0031] A mounting base 1003 is fixedly connected to the side of the receiver 1002, a torque sensor 1005 is fixedly connected to the side of the mounting base 1003, and a detection tooth 1004 is fixedly connected to the rotating shaft of the torque sensor 1005.
[0032] A drive motor 5 is fixedly installed on the side of the outer shell 1. The power shaft of the drive motor 5 extends into the outer shell 1 and is fixedly connected to a drive wheel 6. A driven wheel 7 is rotatably connected inside the outer shell 1. A chain 8 is meshed with the driven wheel 7 and the drive wheel 6. Several sets of hoppers 9 are fixedly connected to the side of the chain 8.
[0033] The outer casing 1 has a feeding port 3 and a discharging port 4 on its two sides respectively. A maintenance cover 12 is fixedly connected to the side of the outer casing 1 by fixing bolts 13. A controller 2 is fixedly connected to the side of the outer casing 1. The controller 2 and the receiver 1002 are electrically connected.
[0034] In this embodiment, during operation, the drive motor 5 drives the drive wheel 6 to rotate, thereby starting the chain 8 normally. The chain 8 drives the detection tooth 1004 to rotate. The torque sensor 1005 connected to the detection tooth 1004 monitors the rotational torque. When the torque is too high and exceeds a set threshold, it indicates that the chain 8 is not sufficiently lubricated. At this time, the torque sensor 1005 transmits the signal to the controller 2 through the receiver 1002. After analyzing the signal, the controller 2 controls the start of the conveying pump 1103 to automatically lubricate the chain 8. The drive motor 5 is controlled by a PLC to precisely control the conveying speed. The torque sensor 1005 is a Honeywell 1388-102 sprocket torque sensor. This device, through the coordinated operation of the integrated monitoring component 10 and the lubrication component 11, establishes a closed-loop management system for monitoring the condition of the chain 8 and dynamic lubrication. The monitoring component 10 can monitor the tension of the chain 8 in real time and synchronously feed it back to the control system, while the lubrication component 11 can accurately locate the lubrication-deficient parts and perform targeted lubrication. Compared with the traditional manual inspection mode, it can significantly reduce the frequency of manual inspection, shorten the downtime for maintenance, significantly improve the operation and maintenance efficiency, and effectively ensure the continuity of bucket elevator operation and the stability of production rhythm.
