Description

Technical Field

[0001] This utility model relates to the technical field of belt conveyor equipment, specifically to a belt conveyor frame high-section anti-jump device. Background Technology

[0002] A belt conveyor, also known as a belt conveyor, is a mechanical device that uses a continuous conveyor belt to transport materials. It achieves continuous material transport by driving the conveyor belt through friction. Due to its high efficiency, energy saving, and high reliability, belt conveyors are widely used in industries such as metallurgy, mining, petrochemicals, coal, building materials, food, and chemicals.

[0003] Belt conveyors can transport both bulk materials and packaged goods. They typically consist of a frame, conveyor belt, conveyor rollers, drive unit, tensioning device, and safety devices. Their working principle is as follows: the conveyor belt wraps around the drive roller and idler roller. Power is transmitted to the conveyor belt through the friction between the drive roller and the conveyor belt, causing it to run continuously on the frame. Materials are placed on the conveyor belt and transported to the designated location as the belt moves. Depending on the conveying requirements, belt conveyors can be classified into low-speed belt conveyors, high-speed belt conveyors, steep-angle belt conveyors, and folding conveyors.

[0004] In coal mine production processes using belt conveyors both underground and on the surface, when pedestrians, material handlers, and belt conveyor lines intersect in time and space, elevated belt conveyors are generally used to create space for pedestrians and material handlers, addressing related impacts. The slope of underground roadways is primarily influenced by geological conditions; sections with varying geological conditions have significant undulations, resulting in significant variations in belt conveyor installation. Due to various factors such as uneven coal loading, belt tension variations, and the start and stop of transport lines, belt skipping frequently occurs. Belt skipping not only causes coal to spill onto the conveyor line, wasting coal resources and increasing cleanup costs, but can also lead to serious problems such as belt tearing and equipment failure, affecting normal coal mine production.

[0005] Therefore, in order to solve the above problems, a high-section anti-slip device for belt conveyors is provided to solve the problem of belt slippage caused by uneven material loading, which leads to belt tearing and equipment failure. Utility Model Content

[0006] The purpose of this utility model is to provide a high-section anti-slip device for a belt conveyor, so as to solve the problem of belt slippage caused by uneven material loading, which leads to belt tearing and equipment failure.

[0007] To achieve the above objectives, the basic solution provided by this utility model is as follows: a high-section anti-jump device for a conveyor belt frame, comprising a crossbeam, longitudinal beams welded to both ends of the crossbeam, a base welded to the other end of the longitudinal beam, a through hole provided on the base, two support beams welded to the crossbeam, screw rods movably connected to the two support beams, springs movably sleeved on the screw rods, and pressure wheels rotatably connected to the screw rods, with the two ends of the springs abutting against the pressure wheels and the support beams respectively.

[0008] The working principle of this utility model is as follows: When in use, the base is first fixed to the frame of the belt conveyor with bolts so that the pressure wheel is in close contact with both sides of the belt. Then, the belt conveyor is started. The belt drives the pressure wheel to rotate at the same time. The pressure wheel limits the two ends of the belt to prevent the belt from running off-track.

[0009] The beneficial effects of this utility model are as follows: By setting an anti-slip device on the frame of the belt conveyor, this utility model can limit the belt on both sides and prevent the belt from jumping in the elevated section. This design can effectively avoid belt jumping or deviation of the belt conveyor, which would lead to belt tearing and equipment failure, thus affecting the normal production of the coal mine.

[0010] Option 2, which is a preferred option of the basic option, has reinforcing rods welded to both of the supporting beams, with the other end of each reinforcing rod welded to the crossbeam; the supporting beams, crossbeams, and reinforcing rods form a triangular system, which can make the supporting beams more stable and robust.

[0011] Option 3, which is a preferred option of the basic option, has a nut threaded onto the screw rod connected to one end of the pressure wheel; by rotating the nut, the position of the nut on the screw rod is adjusted, thereby adjusting the pressure of the pressure wheel.

[0012] Option 4, which is a preferred option of the basic option, has a limiting hole on the support beam, and a limiting plate is movably connected through the screw rod with the spring end movably sleeved on it. A nut is threadedly connected to the screw rod with the spring end movably sleeved on it, and the screw rod slides on the limiting hole. When the equipment is running, the pressure roller can make better contact with the belt in the elevated section of the belt conveyor.

[0013] Option 5, which is a preferred option of the basic option, is a monkey wheel. The monkey wheel has rubber protection to effectively protect the tape and prevent tape wear. In addition, the inner and outer diameters of the monkey wheel are different, which can better contact the tape when installed at an angle.

[0014] Option 6, which is a preferred option of the basic option, is provided with an anchor rod washer between the clamping wheel and the nut, and an anchor rod washer between the limiting plate and the nut; the anchor rod washer can effectively prevent the nut from directly contacting the rotating clamping wheel and thus causing wear, and at the same time, it can also prevent the force from acting directly on the screw rod or nut.

[0019] like Figure 1 and Figure 2 As shown: A high-section anti-jump device for a conveyor belt includes a crossbeam 1, with longitudinal beams 2 welded to both ends of the crossbeam 1. A base 3 is welded to the other end of the longitudinal beam 2, and a through hole 4 is provided on the base 3. Two support beams 5 are welded to the crossbeam 1, and a reinforcing rod 9 is welded to each of the two support beams 5. The other end of the reinforcing rod 9 is welded to the crossbeam 1. A limiting hole 11 is provided on the support beam 5, and a screw rod 6 is movably passed through the limiting hole 11. A pressure wheel 8 is rotatably connected to the screw rod 6. The pressure wheel 8 is a monkey wheel. A spring 7 is movably sleeved on the screw rod 6. The two ends of the spring 7 abut against the pressure wheel 8 and the support beam 5, respectively. Nuts 10 are threaded to both ends of the screw rod 6. An anchor rod washer 13 is provided between the nut 10 and the pressure wheel 8. A limiting plate 12 is movably passed through the screw rod 6 movably sleeved at one end of the spring 7. An anchor rod washer 13 is provided between the limiting plate 12 and the nut 10.

[0020] The implementation method of this embodiment is as follows: In use, first pass the bolt through the through hole 4, and fix the base 3 to the frame of the elevated section and the section of the belt conveyor with large belt undulations by the bolt. Then, rotate the nut 10 as needed to adjust the pressure wheel 8 so that the pressure wheel 8 contacts both sides of the belt. Then start the belt conveyor. The belt drives the pressure wheel 8 to rotate at the same time. When the belt undulates, the pressure wheel 8 drives the screw rod 6 to slide on the limit hole 11, so that the pressure wheel 8 is always in close contact with both sides of the belt, which can prevent the belt from jumping in the elevated section of the belt conveyor.
