Description

Technical Field

[0001] This utility model relates to the field of mining transportation equipment, and in particular to an energy-saving power mechanism for a belt conveyor. Background Technology

[0002] In the field of mining transportation equipment, belt conveyors are the core equipment for ore transfer, but their traditional power mechanisms have significant limitations. Existing equipment mostly uses a single motor drive, with a fixed speed that cannot be dynamically adjusted according to the ore load. Under light loads, high-speed idling wastes energy, while under heavy loads, insufficient power can cause jamming. The deceleration mechanism relies on mechanical braking, which not only suffers from severe wear and high maintenance costs but also leads to material spillage due to uneven deceleration. Furthermore, the lack of a precise load adaptation mechanism makes it difficult to flexibly switch between high and low-speed transportation modes, failing to meet the demand for "high efficiency under light loads and stable operation under heavy loads" in complex mining conditions. This restricts the improvement of transportation efficiency and energy consumption optimization, necessitating a power mechanism with adaptive speed regulation and energy-saving deceleration functions to overcome the existing technological bottlenecks.

[0003] A search revealed patent publication number CN222714340U, which discloses a conveyor belt machine, including a conveyor belt and an iron removal device disposed at the upper end of the conveyor belt. The iron removal device includes a rotating shaft, a belt, and an electromagnetic coil. The belt is disposed on the outside of at least two rotating shafts, and the electromagnetic coil is disposed inside the belt. One end of the rotating shaft is provided with a protrusion, and the other end is provided with a driving component. A connecting seat is provided on the protrusion, and a lifting component I is provided below the connecting seat. A support assembly is provided on the driving component, and a lifting component II is provided below the support assembly. In this invention, cylinders I and II are provided below the iron removal device. When weakly magnetic metal is detected, the height of the iron removal device can be adjusted to make it closer to the conveyor belt, thereby separating the weakly magnetic metal.

[0004] While existing technologies can achieve certain energy-saving effects during use, they suffer from drawbacks: the lack of adaptive speed adjustment capabilities and energy-saving deceleration control mechanisms. In view of this, we propose an energy-saving power mechanism for belt conveyors, which solves the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an energy-saving power mechanism for belt conveyors.

[0006] The technical solution of this utility model is as follows: An energy-saving power mechanism for a belt conveyor includes a first mounting frame and a bidirectional hydraulic cylinder. The bidirectional hydraulic cylinder is fixedly connected to the outer wall of one side of the first mounting frame. A hydraulic rod is provided inside the bidirectional hydraulic cylinder, and both ends of the hydraulic rod are fixedly connected to a moving plate. A first rotating motor is fixedly connected to the outer wall of one end of the moving plate. The output shaft of the first rotating motor is fixedly connected to the input end of a gearbox. The input end of the gearbox is fixedly connected to the rotation center of a first main gear. A frequency converter is fixedly connected to the outer wall of one end of the moving plate. The frequency converter is located on one side of the first rotating motor. When the first main gear meshes with the rotating gear, the conveyor belt operates at high speed.

[0007] When using the energy-saving power mechanism of the belt conveyor in this solution, the pump body moves the hydraulic rod, thereby controlling the movement of the moving plate and meshing different main gears with the rotating gear. When the first main gear meshes with the rotating gear, the first rotating motor provides power to the first main gear through the gearbox, driving the rotating gear to rotate at high speed. At this time, the minerals on the conveyor belt are transported at high speed. When the first rotating motor is running, the output frequency of the motor is dynamically adjusted by the frequency converter, so that the motor speed can be matched with the load of the material on the conveyor frame in real time, thereby achieving energy saving. When the second main gear meshes with the rotating gear, the second rotating motor provides power to the second main gear, driving the rotating gear to rotate at low speed. At this time, the minerals on the conveyor belt are transported at low speed. When it is necessary to decelerate the conveyor belt, the electric control coupling is controlled to make the third rotating motor drive the mating gear to rotate, directly decelerating the rotating gear. Similarly, the mating gear can be accelerated by the third motor when the conveyor belt is moving at low speed, so that it can accelerate the rotating gear to match the speed of the first main gear, and then the first main gear rotates at high speed. Here, the mating gear plays an auxiliary meshing role to prevent damage caused by mismatch in gear meshing speed.

[0008] Preferably, a second mounting bracket is fixedly connected to the outer wall of the other end of the movable plate, and a second rotating motor is fixedly connected to the outer wall of one side of the second mounting bracket. The output shaft of the second rotating motor is fixedly connected to the rotation center of the second main gear, and the operating speed of the second rotating motor is slower than that of the first rotating motor.

[0009] Preferably, two symmetrical third mounting brackets are fixedly connected to one side of the outer wall of the movable plate, and a third rotating motor is fixedly connected to one side of the outer wall of the third mounting bracket.

[0010] Preferably, the output shaft of the third rotary motor is connected to an electrically controlled coupling, which is fixedly connected to one side of the inner wall of the third mounting bracket. The output end of the electrically controlled coupling is connected to the rotation center of the mating gear. By electrically controlling the electrically controlled coupling, the third rotary motor and the mating gear can be coupled and decoupled.

[0011] Preferably, one side of the third mounting bracket is connected to a rotating gear via a bearing, the rotating gear meshes with a mating gear, and the rotation center of the rotating gear is fixedly connected to the rotation center of one end of the conveyor belt.

[0012] Preferably, an oil tank is fixedly connected to the lower outer wall of the first mounting bracket, a pump body is fixedly connected to one side of the outer wall of the oil tank, a connecting pipe is fixedly connected to one end of the pump body, and one end of the connecting pipe is connected to a bidirectional hydraulic cylinder. The oil tank contains hydraulic oil, and the pump body provides pressure to the bidirectional hydraulic cylinder.

[0013] Preferably, the first mounting bracket is provided with two sets of symmetrical guide rails, and the movable plate is disposed on the guide rails, which prevent the movable plate from excessive displacement.

[0014] Preferably, a controller is fixedly connected to one side of the outer wall of the first mounting frame, a conveyor belt is provided inside the first mounting frame, and a monitor is fixedly connected to one side of the upper end of the first mounting frame. The monitor is connected to the controller through a line and converts gravity into an electrical signal and transmits it to the controller.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] I. This utility model achieves the switching and meshing of the first main gear and the second main gear by driving the moving plate with a bidirectional hydraulic cylinder. Combined with the differentiated output of the first rotating motor (high speed) and the second rotating motor (low speed), it realizes the flexible switching of the high and low speed transportation modes of the conveyor belt.

[0017] Second, based on the first beneficial effect, by controlling the engagement and disengagement of the third rotating motor and the mating gear through the electric control coupling, a reverse torque can be applied to the rotating gear when switching between high and low speed modes or when stopping the machine, so as to achieve smooth deceleration of the transmission belt.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] Example 1

[0032] Please see Figures 1-6As shown, this embodiment is an energy-saving power mechanism for a belt conveyor, including a first mounting frame 2 and a bidirectional hydraulic cylinder 6. The bidirectional hydraulic cylinder 6 is fixedly connected to the outer wall of one side of the first mounting frame 2. The bidirectional hydraulic cylinder 6 is provided with a hydraulic rod 5 inside, and both ends of the hydraulic rod 5 are fixedly connected to a moving plate 22. A first rotating motor 12 is fixedly connected to the outer wall of one end of the moving plate 22. The output shaft of the first rotating motor 12 is fixedly connected to the input end of a gearbox 11. The input end of the gearbox 11 is fixedly connected to the rotation center of the first main gear 10. A frequency converter 13 is fixedly connected to the outer wall of one end of the moving plate 22. The frequency converter 13 is located on one side of the first rotating motor 12. During use, when high-speed transportation is required, the bidirectional hydraulic cylinder 6 drives the hydraulic rod 5 to move the moving plate 22, so that the first main gear 10 meshes with the rotating gear 17. After the first rotating motor 12 starts and accelerates through the gearbox 11, it drives the first main gear 10 to rotate at high speed, thereby driving the rotating gear 17 and the transmission belt 1 to achieve high-speed operation. At the same time, the frequency converter 13 dynamically adjusts the output frequency of the first rotating motor 12 according to the load feedback from the monitor 3, so that the motor speed matches the load and achieves energy saving effect.

[0033] Example 2

[0034] Please see Figures 1-6 As shown, this embodiment, based on embodiment 1, further includes: a second mounting bracket 15 fixedly connected to the outer wall of the other end of the movable plate 22; a second rotating motor 14 fixedly connected to the outer wall of one side of the second mounting bracket 15; the output shaft of the second rotating motor 14 fixedly connected to the rotation center of the second main gear 16; in use, when low-speed transportation is required, the bidirectional hydraulic cylinder 6 drives the hydraulic rod 5 to move the movable plate 22 in the opposite direction, so that the second main gear 16 meshes with the rotating gear 17; the second rotating motor 14 starts and drives the second main gear 16 to rotate; since the operating speed of the second rotating motor 14 is slower than that of the first rotating motor 12, the conveyor belt 1 runs at a low speed to meet the working conditions.

[0035] Two symmetrical third mounting brackets 20 are fixedly connected to one side of the outer wall of the movable plate 22. A third rotating motor 19 is fixedly connected to one side of the outer wall of the third mounting bracket 20. In use, the third rotating motor 19 serves as an auxiliary power source and is mainly used for the deceleration control of the conveyor belt 1. When it is necessary to decelerate the conveyor belt 1, the third rotating motor 19 starts and connects to the mating gear 21 through the electric control coupling 18 to prepare for the subsequent deceleration action.

[0036] The output shaft of the third rotating motor 19 is connected to the electric control coupling 18, which is fixedly connected to one side of the inner wall of the third mounting bracket 20. The output end of the electric control coupling 18 is connected to the rotation center of the mating gear 21. When the system receives a deceleration command, the controller 23 first controls the power output of the main motor (either the first rotating motor 12 or the second rotating motor 14 depending on the current mode) to be cut off. Then, the controller 23 engages the electric control coupling 18, so that the power of the third rotating motor 19 is transmitted to the mating gear 21. Through the meshing of the mating gear 21 and the rotating gear 17, a reverse torque is applied to the rotating gear 17, so as to achieve smooth deceleration of the transmission belt 1 and avoid the impact and wear caused by traditional mechanical braking.

[0037] The third mounting bracket 20 is connected to a rotating gear 17 via a bearing on one side. The rotating gear 17 meshes with a mating gear 21. The rotation center of the rotating gear 17 is fixedly connected to the rotation center at one end of the conveyor belt 1. In use, either the first main gear 10 or the second main gear 16 drives the rotating gear 17, and the rotating gear 17 will synchronously drive the rotation center inside the conveyor belt 1 to rotate, thereby realizing the conveying of materials. When deceleration is required, the mating gear 21, driven by the third rotating motor 19, meshes with the rotating gear 17 to generate a reverse force, causing the rotating gear 17 to decelerate, thereby realizing the speed adjustment of the conveyor belt 1.

[0038] An oil tank 9 is fixedly connected to the lower outer wall of the first mounting bracket 2. A pump body 8 is fixedly connected to one side of the outer wall of the oil tank 9. A connecting pipe 7 is fixedly connected to one end of the pump body 8. One end of the connecting pipe 7 is connected to the bidirectional hydraulic cylinder 6. When in use, after the pump body 8 is started, it presses the hydraulic oil in the oil tank 9 into the corresponding chamber of the bidirectional hydraulic cylinder 6, pushing the hydraulic rod 5 to move in the specified direction, thereby driving the moving plate 22 to slide on the guide rail 4, realizing the switching meshing of the first main gear 10 or the second main gear 16 with the rotating gear 17. By controlling the flow rate and pressure of the pump body 8, the moving speed and position of the moving plate 22 can be precisely controlled to ensure the accuracy and stability of gear meshing.

[0039] The first mounting bracket 2 is provided with two sets of symmetrical guide rails 4. The movable plate 22 is mounted on the guide rails 4. In use, the guide rails 4 provide a precise moving path for the movable plate 22, ensuring that the movable plate 22 can slide smoothly and linearly under the drive of the bidirectional hydraulic cylinder 6, preventing the movable plate 22 from deviating or shaking, thereby ensuring the accurate meshing of the first main gear 10, the second main gear 16 and the rotating gear 17. At the same time, the guide rails 4 can also limit the maximum displacement of the movable plate 22, avoiding gear disengagement or damage due to excessive movement.

[0040] A controller 23 is fixedly connected to one side of the outer wall of the first mounting frame 2. A conveyor belt 1 is installed inside the first mounting frame 2. A monitor 3 is fixedly connected to one side of the upper end of the first mounting frame 2. During use, the monitor 3 detects the weight of the material on the conveyor belt 1 in real time and converts the gravity signal into an electrical signal and transmits it to the controller 23. The controller 23 controls the start, stop and direction of the pump body 8 according to the preset control logic and the feedback signal from the monitor 3, so as to switch different main gears and rotating gears 17 to mesh. At the same time, it controls the frequency converter 13 to adjust the output frequency of the first rotating motor 12 and controls the engagement and disengagement state of the electric coupling 18, so as to realize the intelligent and energy-saving operation of the entire power mechanism.

[0041] Instructions for use: When using this device, the pump body 8 moves the hydraulic rod 5, thereby controlling the movement of the moving plate 22, causing different main gears to mesh with the rotating gear 17. When the first main gear 10 meshes with the rotating gear 17, the first rotating motor 12 provides power to the first main gear 10 through the gearbox 11, driving the rotating gear 17 to rotate at high speed. At this time, the minerals on the conveyor belt 1 are transported at high speed. When the first rotating motor 12 is running, the frequency converter 13 dynamically adjusts the motor output frequency, so that the motor speed can be matched in real time according to the load of the material on the conveyor frame, thereby achieving energy saving. When the second main gear 16 meshes with the rotating gear 17, the second rotating motor... Machine 14 provides power to the second main gear 16, driving the rotating gear 17 to rotate at a low speed. At this time, the minerals on the conveyor belt 1 are transported at a low speed. When it is necessary to decelerate the conveyor belt 1, the electric control coupling 18 is controlled to drive the third rotating motor 19 to rotate the mating gear 21, directly decelerating the rotating gear 17. Similarly, the mating gear 21 can be accelerated by the third rotating motor 19 when the conveyor belt 1 is moving at a low speed, so that it can accelerate the rotating gear 17 to match the speed of the first main gear 10, and then the first main gear 10 rotates at a high speed. Here, the mating gear 21 plays an auxiliary meshing role to prevent damage caused by mismatch in gear meshing speed.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
