Description

Technical Field

[0001] The present invention relates to the technical field of belt conveyors, and specifically to a tail roller frame of a belt conveyor for improving transportation capacity. Background Art

[0002] As the core equipment of the mine transportation system, the technical development and application scenarios of coal mine belt conveyors are becoming increasingly diverse. It can achieve long-distance transportation from the mining face to the washing plant or storage area, and is the most commonly used transportation equipment in coal mining.

[0003] However, the coal mine belt conveyor has the following defects in specific use: 1. When the existing coal mine belt conveyor transports the mined coal, it is necessary to pour the mined coal onto the conveyor belt inside the coal mine belt conveyor, and complete the transportation operation of the coal through the movement of the conveyor belt. However, during the transportation of the coal, the coal will be mixed with liquid (water) inside due to reasons such as the mining location and the dust suppression spraying structure during the mining process, which easily causes some coal slag to adhere to the conveyor belt inside the coal mine belt conveyor. At this time, the coal slag adhering to the conveyor belt will affect the stability of the conveyor belt during transportation, and easily cause problems such as the conveyor belt running off track; 2. During daily production, it is found that the belt at the tail of the existing belt conveyor cannot be closely attached to the upper support frame and upper idler, which easily causes the problem of the tail belt running off track. As a result, during the transportation of coal, the conveyor belt of the belt conveyor in a squeezed state during transportation is prone to running off track and being squeezed and torn, affecting the service life of the conveyor belt inside the belt conveyor.

On the other hand, due to the height difference between the oblique conveying rollers and the horizontal conveying rollers, the probability of coal slag sticking to the conveyor belt is reduced, and at the same time, it is convenient for the coal to freely fall and move, improving the efficiency of transporting and discharging the coal‌‌‌‌‌; 3. In the tail roller frame of the belt conveyor for improving transportation capacity, by arranging guiding rollers on the upper and lower sides of the inclined part (edge part) of the conveyor belt, on the one hand, the conveyor belt between the two guiding rollers can be guided to ensure the stability of the conveyor belt during operation and not prone to large displacement.

On the other hand, it can reduce the direct contact between the coupling rod and the embedded block, thereby reducing friction and wear and improving the service life of the equipment. And it can ensure that the coupling rod can freely expand and contract during operation, avoiding jamming or damage caused by thermal expansion or other factors, thereby improving the reliability and stability of the equipment‌‌‌‌‌.

[0019] In order to enable the personnel in the technical field to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0020] Embodiment 1

[0021] Please refer to Figures 1 - 10 , a belt conveyor tail roller frame for improving transportation capacity includes a belt conveyor roller frame 10; a plurality of roller positioning components 20 installed inside the belt conveyor roller frame 10 by screws; an automated conveying and impurity removing mechanism 30 arranged at the tail of the belt conveyor roller frame 10. The automated conveying and impurity removing mechanism 30 is arranged on the side of the roller positioning components 20, and a conveying belt is arranged above the roller positioning components 20 on the outside of the automated conveying and impurity removing mechanism 30. The automated conveying and impurity removing mechanism 30 includes: a displacement tensioning component 301 installed at the tail of the belt conveyor roller frame 10; a first driving source 302 installed on the side of the displacement tensioning component 301; a drive shaft rod 303 connected to the output end of the first driving source 302 and movably arranged inside the displacement tensioning component 301; a first drive belt 304 connected to the outside of the drive shaft rod 303 through a synchronous pulley; a belt conveying component 305 connected to the drive shaft rod 303; a transmission and impurity removing component 306 connected to the inside of the first drive belt 304 through a synchronous pulley. The transmission and impurity removing component 306 is arranged on the side of the belt conveying component 305, and the top of the transmission and impurity removing component 306 abuts against the conveying belt.

[0022] The above working principle: In the transportation operation for coal mining, first, the conveyor belt for transportation is sleeved on the outside of the belt conveyor assembly 305, and the inner top of the conveyor belt abuts against the tops of multiple roller positioning assemblies 20. The positions of the conveyor belt are positioned by the multiple roller positioning assemblies 20, reducing the problem of the conveyor belt running off track during the transportation of coal. At the same time, during the actual transportation of coal by the conveyor belt, the displacement tensioning assembly 301 can adjust the tension force of the conveyor belt during operation by moving back and forth, ensuring that the conveyor belt always abuts against the roller positioning assembly 20, with strong stability. Moreover, the first driving source 302 can be started to operate, driving the drive shaft rod 303 connected to the output end of the first driving source 302 to rotate, and causing the belt conveyor assembly 305 connected to the drive shaft rod 303 to operate, driving the conveyor belt to operate and transport coal. At this time, when the drive shaft rod 303 rotates, it can also drive the first transmission belt 304 to operate, and cause the transmission and impurity removal assembly 306 connected to the inner side of the first transmission belt 304 through a synchronous pulley to operate, continuously vibrating and hitting the conveyor belt, reducing the probability of coal slag adhering to the conveyor belt.

[0023] Specific reference Figure 4 , the roller positioning assembly 20 includes: a longitudinal base 201 installed on the inner top of the belt conveyor frame 10 by screws; a horizontal support 202 installed on the outside of the longitudinal base 201 by screws; an intermediate plate 203 installed between the two horizontal supports 202 by screws; a roller support 204 installed on the tops of the intermediate plate 203 and the horizontal support 202 by screws; and a conveyor roller 205 movably arranged inside the roller support 204.

[0024] In the present invention, there are three conveyor rollers 205 on the tops of one intermediate plate 203 and the horizontal support 202. The conveyor roller 205 located in the middle is longitudinally arranged, and the conveyor rollers 205 located on the left and right sides are obliquely arranged. Moreover, the side of the obliquely arranged conveyor roller 205 close to the horizontal support 202 is lower than the side close to the edge of the belt conveyor frame 10. The top of the conveyor roller 205 abuts against the conveyor belt.

[0025] In the belt conveyor tail frame for improving the transportation capacity of the present invention, through the two obliquely arranged conveyor rollers 205, the bottoms on the left and right sides of the conveyor belt can abut against the tops of the conveyor rollers 205. On the one hand, the position of the conveyor belt is limited through the oblique angle, reducing the probability of the conveyor belt running off track during operation. On the other hand, there is a certain positional difference between the obliquely arranged conveyor rollers 205 and the horizontally arranged conveyor rollers 205. Through this part of the positional difference, the probability of coal slag adhering to the conveyor belt can be reduced.

[0026] Specific reference Figure 4 and Figure 5, on both sides of the top of the horizontal support 202, upper support rods 2021 located on the side of the idler support 204 are installed by screws. An inclined block 2022 is installed on the side of the upper support rod 2021 by screws. A guiding roller 2023 is rotatably connected inside the inclined block 2022. Among them, a conveyor belt is abutted between the two guiding rollers 2023.

Among them, a belt conveying assembly 305 extending to the outside is installed inside the inlaid block 3015.

[0029] In the present invention, the center of the top of the side mounting plate 3011 protrudes outward and forms a convex rod 30111. An installation support 30112 slidably connected to the top of the side mounting plate 3011 is arranged on the outside of the convex rod 30111. A first driving source 302 is installed on the top of the installation support 30112 by screws.

A first transmission belt 304 is movably arranged on one side outside the side mounting plate 3011.

[0030] In the belt conveyor tail roll frame for improving transportation capacity of the present invention, when it is necessary to adjust the tension of the conveyor belt to avoid deviation, by moving the horizontal electric slider 3013 back and forth outside the horizontal slide rail 3012, the belt conveyor assembly 305 installed on the side of the horizontal electric slider 3013 through the guiding support 3014 and the embedded block 3015 can be driven to move back and forth, so that the belt conveyor assembly 305 can adjust the tension of the conveyor belt outside it. At the same time, when the belt conveyor assembly 305 moves, the first driving source 302, the mounting support 30112 and the L-shaped bracket 30113 connected to the belt conveyor assembly 305 can slide horizontally outside the protruding rod 30111 to ensure that the first driving source 302 is always connected to the belt conveyor assembly 305.

[0031] Specific reference Figure 6 and Figure 7 As shown in FIGS. and, the belt conveyor assembly 305 includes: a second transmission belt 3051 connected to the outside of the drive shaft rod 303 through a synchronous pulley; a protective cover 3052 arranged outside the second transmission belt 3051 and mounted on the top of the embedded block 3015; a coupling rod 3053 connected to the inside of the second transmission belt 3051 through a synchronous pulley and rotatably connected to the inside of the embedded block 3015; a conveying wheel 3054 mounted on the outside of the coupling rod 3053 and arranged between the two embedded blocks 3015.

[0035] In the belt tail roller frame for improving the transportation capacity of the present invention, when the drive shaft rod 303 rotates, it will drive the first transmission belt 304 connected to its inner side through a synchronous pulley to operate, and make the movable rod 3061 connected to the inner side of the first transmission belt 304 rotate through a synchronous pulley. At this time, when the movable rod 3061 rotates, it will drive the third transmission belt 3062 connected to its outer side through a synchronous pulley to operate, and make the rotating rod 3063 connected to the inner side of the third transmission belt 3062 rotate through a synchronous pulley. When the rotating rod 3063 rotates, the rotating disc 3064 mounted on its side will rotate, and make the rotating arm 3065 rotatably connected to the eccentric position on the side of the rotating disc 3064 operable. When the rotating arm 3065 operates, the lifting slide rod 3066 and the vibration impurity removal rubber block 3067 rotatably connected to its top will move up and down (reciprocating and in the vertical direction) inside the upper guiding bracket 30661, and continuously act on the inner top of the conveyor belt.

[0038] Embodiment 2

[0039] It is found in use that when the coupling rod 3053 rotates to drive the conveyor belt to operate for the transportation operation of coal mines, because the coupling rod 3053 needs to operate for a long time, the friction between the coupling rod 3053 and the inner wall of the embedded block 3015 is large, and the coupling rod 3053 is prone to thermal expansion or even damage due to frictional heat generation, and the safety is relatively low.

[0040] Therefore, specifically referring to Figure 11 and Figure 12 , an outer protrusion 40 is installed outside the coupling rod 3053, the outer protrusion 40 is movably arranged inside the embedded block 3015, a tapered groove 401 is further opened inside the embedded block 3015 on the side of the outer protrusion 40, a sealing head 402 installed on the side of the embedded block 3015 by screws is arranged inside the tapered groove 401, and the coupling rod 3053 penetrates through the inside of the sealing head 402. Among them, a gap of 1 mm to 2 mm is left between the tapered groove 401 and the outer wall of the coupling rod 3053, and the cross-sectional area of the tapered groove 401 on the side close to the conveyor wheel 3054 is larger than the cross-sectional area on the side close to the second transmission belt 3051.

[0041] In the belt tail roller frame for improving transportation capacity of the present invention, through the design of the sealing head 402, the installation and disassembly of the coupling rod 3053 and the conveyor wheel 3054 can be operated simply and conveniently, which is convenient for subsequent maintenance. At the same time, the gap left between the coupling rod 3053 and the inner wall of the embedded block 3015, on the one hand, allows the coupling rod 3053 to freely extend during thermal expansion, avoids the embedded block 3015 from bearing additional loads, and ensures normal operation. On the other hand, it can reduce the direct contact between the coupling rod 3053 and the embedded block 3015, thereby reducing friction and wear and enhancing the service life of the equipment. And it can ensure that the coupling rod 3053 can freely expand and contract during operation, avoid jamming or damage caused by thermal expansion or other factors, and thus improve the reliability and stability of the equipment.
