Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to a turning device on a belt conveyor. Background Art

[0002] Belt conveyor, also known as belt conveyor, is a kind of transportation machinery, which is widely used in coal, metallurgy, transportation, electricity, building materials, chemical industry, port and other industries. Its layout forms are divided into horizontal transportation, upward transportation, downward transportation and plane turning transportation.

[0003] The turning phenomenon of belt conveyors is relatively common, especially when encountering large turning angles. On the ground, there is a large turning space without being affected by the surrounding environment, and the turning radius of the belt conveyor can reach more than 1000m. However, in coal mine tunnels, due to limited space, the turning radius is also limited, and the turning problem of the belt conveyor needs to be considered.

[0004] There are two common solutions:

[0005] 1. Belt conveyors overlap each other;

[0006] Disadvantages of this solution: 1. It increases the unloading points and fault points, which require special personnel to guard, especially multiple turns and S-shaped turns. This solution is difficult; 2. It increases the cost. Each belt conveyor needs to be equipped with a series of components such as drive motors and tensioners, and the foundation of the belt conveyor needs to be laid;

[0007] 2. Use a forced turning device;

[0008] The disadvantages of this solution are: 1. The forced turning device is large in size and complex in structure. The forced turning itself is expensive and requires processing in the lane, so the initial investment cost is high. 2. The forced turning device will affect the service life of the belt. 3. The forced turning device has serious wear problems on the special-shaped rollers, and the operating cost is high. 4. An additional unloading point is added, which requires special personnel to guard.

[0009] Therefore, the traditional solution has high requirements for the construction site, which is bound to increase the on-site construction volume and maintenance and management costs to meet the installation and use requirements of the equipment; moreover, in traditional belt conveyors, the conveyor belts in the turning sections are not pressed or blocked, which can easily cause the conveyor belts to climb the rollers, affecting the normal transportation of materials by the conveyor belts.

[0043] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0044] like Figures 1 to 4As shown in the figure, the utility model includes an intermediate frame 1, an upper support frame 2, an upper roller mechanism 3 and an upper pressure belt deflection blocking mechanism 4; wherein the upper support frame 2 is installed on the intermediate frame 1, and the upper support frame 2 includes an upper column 1 21 and an upper column 22; wherein at least one upper roller mounting hole 23 is opened on the upper column 1 21, and at least one upper roller adjustment hole 24 is opened on the upper column 22; the upper roller mechanism 3 includes an upper support frame 21 installed between the upper column 1 21 and the upper column 22 Roller frame 31, one end of the upper roller frame 31 is connected to the upper column 21 through the upper roller mounting hole 23, the other end of the upper roller frame 31 is connected to the upper column 22 through the upper roller adjustment hole 24, and an upper roller group 32 is rotatably mounted on the upper roller frame 31; the angle a between the upper roller mechanism 3 and the horizontal plane is 0°~10°; the upper roller frame 31 can be adjusted in angle along the length direction of the conveyor belt 7, and the angle between the upper roller frame 31 and the center line of the conveyor belt 7 is 0°~2°. The two ends of the upper roller frame 31 are connected to the upper column 1 21 and the upper column 22 through the upper roller mounting hole 23 and the upper roller adjustment hole 24 respectively. One end of the upper roller frame 31 can rotate around the upper roller mounting hole 23, so that the other end of the upper roller frame 31 moves up, forming an angle with the horizontal plane, and at the same time drives one end of the upper roller group 32 to move up together, so that there is also an angle between the upper roller group 32 and the horizontal plane, forming an inner curve lifting angle. The angle of the inner curve lifting angle gradually increases, which can be adapted to the forces of different turns and the needs of changes in the lane, and meet the requirements for turning the belt conveyor in the lane. There is no need to overlap the belt conveyor and add a forced turning device, which reduces the cost, reduces the difficulty of maintenance, and also reduces the civil construction in the lane.

[0049] In the present application, an anti-floating belt mechanism 5 is installed between the upper column 1 21 and the upper column 2 22, and the anti-floating belt mechanism 5 is arranged above the upper roller group 32. The anti-floating belt mechanism 5 prevents the conveyor belt 7 from floating due to a large angle change, and can change with the change of the angle of the upper roller group 32 and the position can be adjusted arbitrarily. At least one anti-floating belt installation hole 25 is opened on the upper column 1 21, and at least one anti-floating belt adjustment hole 26 is opened on the upper column 22; the anti-floating belt mechanism 5 includes an anti-floating belt frame 51, one end of the anti-floating belt frame 51 is connected to the upper column 1 21 through the anti-floating belt installation hole 25, and the other end of the anti-floating belt frame 51 is connected to the upper column 22 through the anti-floating belt adjustment hole 26. The bottom of the anti-floating belt frame 51 is rotatably installed with an anti-floating belt pressure roller 52, and the center line of the anti-floating belt pressure roller 52 is collinear with the center line of the upper roller group 32. The two ends of the anti-floating belt frame 51 are connected to the upper column 1 21 and the upper column 22 respectively through the anti-floating belt mounting hole 25 and the anti-floating belt adjustment hole 26. One end of the anti-floating belt frame 51 can rotate around the anti-floating belt mounting hole 25, so that the other end of the anti-floating belt frame 51 moves up, driving one end of the anti-floating belt pressure roller 52 to move up together, so that the anti-floating belt pressure roller 52 and the upper roller group 32 move up together. Similarly, there is also an angle between the anti-floating belt pressure roller 52 and the horizontal plane, and the angle is 0° to 10° to prevent the streamer, and the position is adjustable.
