Description

Technical Field

[0001] This utility model belongs to the field of conveyor technology, specifically relating to a shock absorption device for belt conveyors. Background Technology

[0002] Belt conveyors are widely used material transport equipment in industries such as mining, metallurgy, power, and coal, offering advantages such as high efficiency and continuous material transport. During operation, especially when conveying long distances, heavy loads, and heavy materials, belt conveyors generate significant vibration and noise, affecting equipment lifespan and the working environment for personnel. Therefore, vibration damping devices play a crucial role in belt conveyors.

[0003] Chinese patent publication number CN 210635280 U discloses a vibration damping device for a belt conveyor, including a fixed plate. Several rows of opposing fixed frames are fixed to both sides of the upper surface of the fixed plate, and two fixed seats are fixed to the upper surface of the fixed plate in the same row as the fixed frames. A bent portion is provided at the top of the fixed frame, and a first sliding groove extending to the top is formed on the inner surface of the bent portion. A first top cover plate is fixed to the top of the fixed frame. This invention provides side guide rollers and a middle guide roller between the fixed seats and the fixed frames. The guide rollers are mounted on a slider, and a vibration damping spring is provided between the slider and the fixed seats and fixed frames. This provides vibration damping protection for the guide rollers and the conveyor belt at different angles, overcoming the lateral and longitudinal fluctuations of the conveyor belt and improving the operational stability of the equipment.

[0004] However, current vibration damping devices for belt conveyors have the following problems: they cannot delay the rebound of the springs and cannot guarantee the stability of the internal components of the belt conveyor, which leads to the inability to extend the service life of the belt conveyor. Therefore, we propose a vibration damping device for belt conveyors. Utility Model Content

[0005] The purpose of this invention is to provide a shock-absorbing device for belt conveyors that cannot delay the rebound of springs and cannot guarantee the stability of internal components of belt conveyors, thus failing to extend the service life of belt conveyors.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] The system includes a support leg, to which a rotating shaft motor is fixedly connected. The output shaft of the rotating shaft motor is fixedly connected to a rotating rod, and a conveyor belt is drivenly connected to the outer surface of the rotating rod. A shock-absorbing device is installed at the bottom of the support leg. The shock-absorbing device includes a shock-absorbing plate, which is fixedly connected to the bottom of the support leg. A cylinder is fixedly connected to the bottom of the shock-absorbing plate, and a spring is installed on the outer surface of the cylinder. A U-shaped plate is slidably connected to the bottom of the shock-absorbing plate. The shock-absorbing plate slides up and down along the inner wall of the U-shaped plate.

[0008] Preferably, the herringbone plate has a groove, the bottom of the herringbone plate has a circular groove, and the bottom of the herringbone plate is fixedly connected to a load-bearing leg.

[0009] Preferably, there are two cylinders, which are symmetrical to each other along the vertical central axis of the damping plate, and the cylinders are slidably connected to the inner wall of the circular groove.

[0010] Preferably, the shock-absorbing plate is located on the movement trajectory of the groove, and the number of the load-bearing legs is set to four, in pairs, and symmetrical to each other along the vertical central axis of the return plate.

[0011] Preferably, the bottom of the shock-absorbing plate is provided with a buffer device, including a force-bearing shaft, which is fixedly connected to the bottom of the shock-absorbing plate, and a fixing plate is fixedly connected to the outer surface of the force-bearing shaft.

[0012] Preferably, a long rod extends through the outer surface of the fixing plate, a connecting rod is hinged to the outer surface of the long rod, a fixing block is fixedly connected to the outer surface of the connecting rod, a short rod extends through the front side of the fixing block, a force-bearing block is fixedly connected to the bottom of the fixing block, and a sponge block is provided on the side of the force-bearing block.

[0013] Preferably, there are two connecting rods, which are symmetrical to each other along the vertical central axis of the force axis, and the fixing block is located on the movement trajectory of the connecting rod. The technical effect achieved by this utility model is as follows:

[0014] This invention utilizes components such as a damping plate, spring, cylinder, and U-shaped plate to work together. The spring can use its own elasticity to drive the damping plate to move upward. The spring absorbs the energy of vibration, preventing these vibrations from being directly transmitted to the conveyor belt. This reduces the vibration of the belt conveyor, achieves a damping effect, ensures the stability of the internal components of the belt conveyor, and thus extends the service life of the belt conveyor.

[0015] This invention utilizes a combination of components such as a long rod, connecting rod, fixing block, and force-bearing block to achieve a linear upward movement of the force-bearing axis when the damping plate moves upward under the elastic force of the spring. This forces the force-bearing plate, connecting rod, and force-bearing block to reset. At this time, the sponge block loses its force and slowly returns to its original state, which can delay the upward rebound of the spring, thereby reducing the vibration amplitude of the belt conveyor and enhancing the stability of the internal components of the belt conveyor.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figure 1-5 As shown, a shock-absorbing device for a belt conveyor includes a support leg 1. A rotating shaft motor 2 is fixedly connected to the outer surface of the support leg 1. A rotating rod 3 is fixedly connected to the output shaft of the rotating shaft motor 2. A conveyor belt 4 is drivenly connected to the outer surface of the rotating rod 3. A shock-absorbing device 5 is provided at the bottom of the support leg 1. The shock-absorbing device 5 includes a shock-absorbing plate 51, which is fixedly connected to the bottom of the support leg 1. A cylinder 52 is fixedly connected to the bottom of the shock-absorbing plate 51. A spring 53 is provided on the outer surface of the cylinder 52. A loop plate 54 is slidably connected to the bottom of the shock-absorbing plate 51.

[0025] The U-shaped plate 54 has a groove 55 and a circular groove 56 at the bottom. A load-bearing leg 57 is fixedly connected to the bottom of the U-shaped plate 54. The circular groove 56 allows the cylinder 52 to slide on the inner wall of the circular groove 56 when it moves downward under force.

[0026] There are two cylinders 52, which are symmetrical to each other along the vertical central axis of the damping plate 51. The cylinders 52 are slidably connected to the inner wall of the circular groove 56, and the cylinders 52 can cause the spring 53 to contract under force.

[0027] The shock-absorbing plate 51 is located on the movement trajectory of the groove 55. There are four load-bearing legs 57, which are arranged in pairs and symmetrical to each other along the vertical central axis of the loop plate 54. The load-bearing legs 57 can make the belt conveyor run more smoothly.

[0028] According to the above structure, when the belt conveyor starts to operate, the belt conveyor will generate vibration. In order to reduce the vibration generated during the operation of the belt conveyor, when the belt conveyor vibrates, the damping plate 51 fixed at the bottom of the support leg 1 is vibrated. When the damping plate 51 moves downward first, the force shaft 61 fixed at the bottom of the damping plate 51 moves downward on the inner wall of the circular groove 56. The spring 53 is compressed by force. Since the spring 53 is elastic, the spring 53 can use its own elastic force to drive the damping plate 51 to move upward. The setting of the spring 53 will absorb the vibration energy and prevent these vibrations from being directly transmitted to the conveyor belt 4, thereby reducing the vibration of the belt conveyor, achieving the effect of shock absorption, ensuring the stability of the internal components of the belt conveyor, and thus extending the service life of the belt conveyor.

[0029] like Figure 1-5 As shown, a buffer device 6 is provided at the bottom of the damping plate 51, including a force-bearing shaft 61. The force-bearing shaft 61 is fixedly connected to the bottom of the damping plate 51, and a fixing plate 62 is fixedly connected to the outer surface of the force-bearing shaft 61. The fixing plate 62 can enhance the stability of the force-bearing shaft 61 structure.

[0030] A long rod 63 extends through the outer surface of the fixing plate 62. A connecting rod 64 is hinged to the outer surface of the long rod 63. A fixing block 65 is fixedly connected to the outer surface of the connecting rod 64. A short rod 66 extends through the front and side of the fixing block 65. A force-bearing block 67 is fixedly connected to the bottom of the fixing block 65. A sponge block 68 is provided on the side of the force-bearing block 67. The sponge block 68 can reduce the elasticity of the spring 53.

[0031] There are two connecting rods 64, which are symmetrical to each other along the vertical central axis of the force axis 61. The fixing block 65 is located on the movement trajectory of the connecting rod 64. The connecting rod 64 can connect the long rod 63 and the short rod 66 to each other.

[0032] According to the above structure, when the belt conveyor 4 starts operating, the damping plate 51 is subjected to force, causing the force shaft 61 to move downward. This forces the fixed plate 62 to drive the long rod 63 to move downward as well, and forces the connecting rod 64 to move downward in an arc through the fixed block 65. At this time, the short rod 66 fixed to one end of the connecting rod 64 drives the fixed block 65 to slide on the bottom of the inner wall of the U-shaped plate 54 through the force block 67. At this time, the sponge block 68 is compressed by the pressure of the force block 67. When the damping plate 51 moves upward under the elastic force of the spring 53, it drives the force shaft 61 to move upward in a straight line, forcing the fixed plate 62, connecting rod 64, force block 67 and other components to reset. At this time, the sponge block 68 loses force and slowly returns to its original state, which can delay the upward elasticity of the spring 53, thereby reducing the amplitude of the belt conveyor vibration and enhancing the stability of the internal components of the belt conveyor.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
