Technical Field

[0001] The utility model relates to the technical field of intelligent coal flow control, in particular to an intelligent coal flow control load bridge assembly. Background Art

[0002] The main function of the intelligent coal flow control load bridge assembly is to monitor and control the coal flow to improve the efficiency and quality of coal flow transportation. By installing sensors, the flow, speed, temperature, concentration and other parameters of the coal flow can be monitored in real time and the data can be transmitted to the control system. The control system automatically adjusts the operating status of the coal flow conveying equipment according to the preset algorithms and parameters to achieve the optimal coal flow transportation effect.

[0003] The upper and lower ends of the load bridge assembly are mostly in direct contact with the conveyor belt that transports coal blocks. However, the traditional load bridge assembly is not equipped with a structure to prevent the conveyor belt from shifting at the contact point with the conveyor belt, which may cause the conveyor belt to shift when it rotates to the position of the load bridge assembly, thereby causing inaccurate detection results of the lower end load sensor, affecting the subsequent coal flow transportation effect. Furthermore, we disclose an intelligent coal flow control load bridge assembly to meet the actual needs of the traditional load bridge assembly, which is not equipped with a structure to prevent the conveyor belt from shifting at the contact point with the conveyor belt, resulting in the conveyor belt being easily shifted, thereby causing inaccurate detection results of the lower end load sensor, affecting the subsequent coal flow transportation effect. Utility Model Content

[0004] In view of this, the purpose of the utility model is to propose an intelligent coal flow control load bridge assembly to solve a series of problems such as the traditional load bridge assembly is not provided with a structure to prevent the conveyor belt from shifting at the part in contact with the conveyor belt, which makes the conveyor belt easy to shift, thereby causing inaccurate detection results of the lower end load sensor, affecting the conveying effect of the subsequent coal flow, etc.

[0005] Based on the above-mentioned purpose, the utility model provides an intelligent coal flow control load bridge assembly, including an outer frame, the internal bolts of the outer frame are connected to the inner frame, the outer sleeve of the inner frame is provided with a conveyor belt for conveying the coal flow, the upper and lower ends of the inner frame are provided with detection components for weighing the total weight of the coal flow on the conveyor belt, the connection between the conveyor belt and the detection component is provided with an anti-deviation structure, and a coal scraper component is provided on one side of the outer frame, and the coal scraper component includes a scraper whose lower end is tightly fitted to the outer wall of the conveyor belt.

[0006] Preferably, load sensors are provided on both sides of the upper and lower ends of the inner frame, and pressure plates are provided outside the plurality of load sensors.

[0007] Preferably, a connecting rod is bolted between the pressure plates at both sides of the upper and lower ends.

[0008] Preferably, the upper end surface of the pressing plate is provided with evenly spaced card slots, and the cross-section of the card slots is trapezoidal.

[0009] Preferably, a plurality of clamping blocks are fixedly connected to both sides of the inner wall of the conveyor belt, and the clamping blocks are slidably clamped in the inside of the clamping groove.

[0010] Preferably, the block is made of polyurethane rubber material, and the cross section of the block is trapezoidal.

[0011] Preferably, a plurality of ball heads are rotatably clamped at even intervals on the upper end surface of the pressure plate.

[0012] Preferably, buffer springs are fixedly connected to both ends of one side of the upper end of the scraper, and a mounting plate with mounting bolts is fixedly connected to the upper ends of the two buffer springs.

[0013] Preferably, the cross section of the scraper is designed to be "L"-shaped, and an arc-shaped groove is opened in the middle of the scraper.

[0014] Preferably, the arc-shaped groove has an inclined angle.

[0015] Beneficial effects of the utility model:

[0016] 1. The intelligent coal flow control load bridge assembly. When the load bridge assembly is in use, an anti-deviation structure is arranged at the connection between the conveyor belt and the load frame, a slot is arranged on the pressure plate, a card block is fixedly connected to the conveyor belt, the card block is slidably engaged and connected inside the slot, and the cross-sections of the slot and the card block are both trapezoidal in design, so the conveyor belt is not easy to deviate. In addition, a ball head is rotatably engaged between the pressure plate and the conveyor belt, which greatly reduces the friction between the conveyor belt and the pressure plate and reduces the degree of wear on the conveyor belt. The anti-deviation structure can prevent the conveyor belt from deviating easily when it rotates to the load frame, thereby improving the accuracy of the detection result of the lower end load sensor.

[0017] 2. The intelligent coal flow control load bridge assembly. When the load bridge assembly is in use, a coal scraper assembly is added to one side of the outer frame. The coal scraper assembly is composed of a scraper with an "L"-shaped cross-section. The lower end of the scraper is in close contact with the conveyor belt, and the coal remaining on the conveyor belt is collected into the internal arc groove. Since the arc groove has an inclined angle, the coal slides out of the scraper along the arc groove. A buffer spring is arranged at the upper end of the scraper. The buffer spring can be used to buffer and retract the scraper, which greatly reduces the possibility of damage to the scraper caused by stubborn coal blocks. The coal scraper assembly makes it difficult for coal slag to remain on the surface of the conveyor belt when it completes a circle of rotation and receives coal again, thereby further improving the detection accuracy of the subsequent load detection device.

[0029] like Figures 1 to 6 As shown, the intelligent coal flow control load bridge assembly includes an outer frame 2, the internal bolts of the outer frame 2 are connected to the inner frame 3, the outer sleeve of the inner frame 3 is provided with a conveyor belt 1 for conveying the coal flow, the upper and lower ends of the inner frame 3 are provided with detection components for weighing the total weight of the coal flow on the conveyor belt 1, and an anti-deviation structure is provided at the connection between the conveyor belt 1 and the detection component, and a coal scraping component is provided on one side of the outer frame 2. The coal scraping component includes a scraper 9 whose lower end is tightly fitted to the outer wall of the conveyor belt 1. When the load bridge assembly is in use, an anti-deviation structure is provided at the connection between the conveyor belt 1 and the load frame. The anti-deviation structure can prevent the conveyor belt 1 from being easily deviated when it rotates to the load frame, thereby improving the accuracy of the detection result of the lower end load sensor 4. In addition, a coal scraping component is added. The coal scraping component prevents coal slag from remaining on the surface of the conveyor belt 1 when it completes a circle of rotation and receives coal again, thereby further improving the detection accuracy of the subsequent load detection device.

[0030] Further, such as Figure 1 to Figure 2 and Figure 6As shown, load sensors 4 are provided on both sides of the upper and lower ends of the inner frame 3, and pressure plates 5 are provided on the outside of the multiple load sensors 4. Connecting rods 6 are bolted between the pressure plates 5 on both sides of the upper and lower ends. Card grooves 12 are evenly spaced apart on the upper end surface of the pressure plate 5. The cross section of the card groove 12 is trapezoidal. Multiple card blocks 11 are fixedly connected on both sides of the inner wall of the conveyor belt 1. The card blocks 11 are slidably connected to the inside of the card grooves 12. The card blocks 11 are made of polyurethane rubber material. The cross section of the card block 11 is trapezoidal. Multiple ball heads 13 are evenly spaced and rotatably connected to the upper end surface of the pressure plate 5. When the load bridge assembly is in use, the conveyor belt 1 and the load frame body are connected. An anti-deviation structure is provided at the connection, a slot 12 is provided on the pressure plate 5, a block 11 is fixedly connected to the conveyor belt 1, the block 11 is slidably engaged in the slot 12, and the cross-sections of the slot 12 and the block 11 are both trapezoidal in design, so the conveyor belt 1 is not easily deviated. In addition, a ball head 13 is rotatably engaged between the pressure plate 5 and the conveyor belt 1, which greatly reduces the friction between the conveyor belt 1 and the pressure plate 5 and reduces the degree of wear on the conveyor belt 1. The anti-deviation structure can prevent the conveyor belt 1 from deviating easily when it is rotated to the load frame, thereby improving the accuracy of the detection result of the lower end load sensor 4.

[0031] Further, such as Figures 4 to 5 As shown, both ends of the upper end of the scraper 9 are fixedly connected with buffer springs 7, and the upper ends of the two buffer springs 7 are fixedly connected with mounting plates 8 with mounting bolts. The cross section of the scraper 9 is designed in an "L" shape, and an arc groove 10 is opened in the middle of the scraper 9. The arc groove 10 has an inclined angle. When the load bridge assembly is in use, a coal scraping assembly is added to one side of the outer frame 2. The coal scraping assembly consists of a scraper 9 with an "L" shaped cross section. The lower end of the scraper 9 is in close contact with the conveyor belt 1 to collect the residual coal on the conveyor belt 1. The scraper 9 is inserted into the internal arc groove 10. Since the arc groove 10 has an inclined angle, the coal material slides out of the scraper 9 along the arc groove 10. A buffer spring 7 is arranged at the upper end of the scraper 9. The buffer spring 7 can buffer and retract the scraper 9, which greatly reduces the possibility of damage to the scraper 9 caused by stubborn coal blocks. The coal scraping assembly is arranged to prevent coal slag from remaining on the surface of the conveyor belt 1 when it completes a circle of rotation and receives coal again, thereby further improving the detection accuracy of the subsequent load detection device.
