[0001] The utility model relates to a monitoring device for observing the state of the internal lining plate of a chute and the feeding amount, belonging to the technical field of monitoring. Background Art
[0002] The chute is an important part of port loading equipment. Generally, it is installed at the head of the belt conveyor to change the material flow direction for stacking, and it is an important feeding device for loading ships and stacking materials in the yard. In the actual application process, a large number of anti-wear lining plates need to be installed inside the chute to reduce the impact on the chute skin when the material changes direction. Excessive wear of the lining plate will cause the lining plate to fall off, and the fallen lining plate mixed into the material will cause freight quality accidents. At the same time, during the actual feeding process, if the feeding amount is too large, it will cause the chute to be blocked, making the equipment unable to operate normally. Therefore, it is very necessary to design a monitoring device for observing the state of the internal lining plate of the chute and the feeding amount. Content of the Utility Model
[0003] The purpose of the utility model is to provide a chute safety monitoring system for the disadvantages of the existing technology, so as to avoid freight quality accidents caused by the falling off of the lining plate and prevent the chute from being blocked due to excessive feeding amount.
[0004] To achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A chute safety monitoring system includes a high-definition camera, an electric push rod, a rotating rod and a rotating rod bracket. The electric push rod is rotatably connected to the top plate of the chute. An observation port is opened on the top plate of the chute. The rotating rod bracket is fixed on the top plate of the chute and is located between the electric push rod and the observation port. The middle part of the rotating rod is rotatably connected to the rotating rod bracket. One end of the rotating rod is rotatably connected to the electric push rod, and the other end is connected to the high-definition camera.
[0006] The above-mentioned chute safety monitoring system further includes a cover plate trolley and two slideways. The two slideways are parallel to each other and are respectively fixed on both sides of the observation port. Both sides of the cover plate trolley are slidably connected to the two slideways through rollers.
[0007] In the above-mentioned chute safety monitoring system, a limit bracket is arranged between the rotating rod bracket and the electric push rod. The limit bracket is fixed on the top plate of the chute, and a sheep's horn limit corresponding to the rotating rod is arranged at the top of the limit bracket.
[0008] In the above-mentioned chute safety monitoring system, the rotating rod bracket includes a rotating shaft and two triangular brackets. The two triangular brackets are installed in parallel on the top plate of the chute. Both ends of the rotating shaft are respectively fixed to the tops of the two triangular brackets. The rotating rod is perpendicular to the rotating shaft, and the middle part of the rotating rod is rotatably connected to the rotating shaft through a bearing.
[0009] The utility model utilizes an electric push rod to drive the rotating rod to rotate, so that a high-definition camera installed on the rotating rod enters the chute from an observation port on the top plate of the chute to observe the internal situation of the chute. Once it is found that the liner is severely worn or the material flow is too large, the operator is immediately notified to take timely treatment measures to avoid the liner falling off and causing freight quality accidents, and to prevent the chute from being blocked by excessive feeding, so as to ensure the safe operation of the equipment.

[0015] The utility model provides a chute safety monitoring system to solve the problems in the prior art. The system can monitor the state of the lining plate inside the chute to ensure that the lining plate is intact and replace it in time when it is found to be worn. The size of the material flow can also be observed during the operation to prevent the chute from being blocked.
[0016] See also Figures 1-3 The utility model mainly includes a high-definition camera 1, a cover trolley 2, an electric push rod 3, a slide 4, a triangular bracket 5, a rotating rod 6, a limit bracket 8 and a horn limit 9.
[0017] First, an observation port 7 is opened on one side of the top plate of the chute 10. The length of the observation port 7 is 1m and the width is 0.5m to ensure that the high-definition camera 1 can be fully inserted. Two channel steels (length 2m, width 3mm) are welded on both sides of the observation port 7 as the slideway 4. The cover trolley 2 is made of steel plate (length 1m, width 0.5m, thickness 5mm), and two rollers (roller width 2.5mm) are installed on both sides of the steel plate. The cover trolley 2 is placed on the channel steel for sliding operation. When it is necessary to observe the internal situation of the chute 10, the cover trolley 2 slides to one side. When encountering bad weather, the observation port 7 is closed to prevent smoke, dust and rain from polluting the transported materials. On the other side of the top plate of the chute 10, two triangular brackets 5 are installed in parallel (the brackets are right triangles, with a height of 0.8m, a width of 5cm, and a material thickness of 3mm steel plate). A round steel (diameter 3mm, length 0.4m) is welded and fixed between the tops of the two triangular brackets 5 as a rotating shaft 12. A bearing is installed at the center of the round steel. The outer ring of the bearing is connected to the rotating rod 6. A high-definition camera 1 is installed at one end of the rotating rod 6. The other end of the rotating rod 6 is rotatably connected to the top of the electric push rod 3. The electric push rod 3 is rotatably connected to the top plate of the chute 10. An F-type limit bracket 8 is made of a square tube, and a mechanical horn limit 9 is installed on it. When the rotating rod 6 touches the horn limit 9, the action of the electric push rod in that direction is stopped, ensuring that the electric push rod 3 always works within the set area and preventing the electric push rod 3 from being damaged due to excessive rotation angle.
[0018] The method of using the utility model is as follows: when the material flow is generated and the chute 10 is working, the cover trolley 2 slides to one side along the slideway 4 to open the observation port 7. The electric push rod 3 is lifted upward to rotate the rotating rod 6 around the rotating shaft 12 on the triangular bracket 5, and the high-definition camera 1 is put into the chute 10 from the observation port 7 to monitor the internal situation of the chute 10 and observe the wear of the internal impact surface lining and the size of the material flow. If the impact surface lining is found to be seriously worn, stop the machine in time for replacement. If the material flow is found to be too large, notify the operator in time to reduce the flow to prevent the lining from falling off and the chute from being blocked.
[0019] The utility model adopts two triangular brackets to support the rotating rod 6, so as to ensure that the high-definition camera does not shake during the monitoring process, thereby improving the picture quality. The cover trolley can close the chute in time when encountering extremely bad weather conditions to prevent smoke, dust and rain from polluting the transported materials. The electric push rod can adjust the height and observation angle of the camera at will, so as to facilitate the observation of the state of the lining plate and the material flow. Under normal circumstances (except for bad weather), the whole set of equipment does not require manual operation and runs completely automatically, which can save a lot of manpower.
[0020] An embodiment of the present utility model is as follows:
[0021] Materials used: 2 mechanical horn limiters (model MA 471-03 / 03Y, manufacturer: Schmersal), 1 electric push rod (model LEC608-3000-200-18-24-450, manufacturer: Suzhou Yuancheng Mingchuang Electromechanical Equipment Co., Ltd.), 1 HD camera (4 million 2K HD starlight night vision camera, manufacturer: Hikvision, model: 3T46WDV3-I34mm), round steel (diameter 3mm, length 2m). Steel plate (length 1m, width 0.5m, thickness 5mm) 0.5㎡, channel steel width 3mm length 4m, steel plate (thickness 3mm) 1㎡, square tube 1.5m.
[0022] The chute used on site at a coal port adopts the utility model, and the transformation cost is about 20,000 yuan per unit. After adopting the utility model, it is conservatively estimated that the failure time of the chute can be reduced by more than 10 hours per year. According to the efficiency estimate of 3,000 tons / hour (taking into account the coal blending factor), the company can transport 30,000 tons of coal more per year. According to the profit of about 12 yuan per ton of coal, the economic benefit can be created annually. About 360,000 yuan, the benefit improvement is very considerable.
