Description

Technical Field

[0001] The present invention mainly relates to the technical field of raw coal transportation, and in particular to an auxiliary buffer support device for reducing the vibration and swaying degree of a raw coal bin. Background Art

[0002] Coal-fired power plants mostly use raw coal bunkers to store coal between coal feeders. During the process of discharging materials from the bunker, it is often necessary to knock on the bunker to reduce the phenomenon of material blockage.

[0003] According to a device for preventing and dredging the raw coal bunker of a thermal power plant provided in the patent document with application number CN202022781214.0, the device includes an airflow injection layer and a pneumatic hammering layer. The airflow injection layer is provided with several layers and the airflow injection layer is used to spray high-pressure airflow into the inner cavity of the raw coal bunker. The pneumatic hammering layer is provided with several layers and the pneumatic hammering layer is provided on the outer wall of the raw coal bunker. An airflow injection layer and / or a pneumatic hammering layer are provided between the inlet and outlet of the raw coal bunker. The utility model can dredge the raw coal bunker as a whole, ensure the smooth flow of coal in each section of the raw coal bunker, and ensure the normal operation of the coal conveying of the coal feeder. The overall scheme is simple in structure, with minor changes to the original anti-blocking and dredging system, reasonable structure, reliable operation, cost saving, easy maintenance, and convenient on-site installation and modification. It greatly broadens the adaptability of coal types and improves the level of coal utilization.

[0004] Although the above-mentioned anti-blocking dredging device has the advantages of being easy to install and modify on site and greatly broadening the adaptability of coal types, traditional dredging devices often require the use of a pneumatic hammer to vibrate the raw coal bunker to drive the coal bunker to vibrate in order to complete the loosening work, but lacks buffering and support for the coal bunker, resulting in a short service life of the coal bunker. Summary of the invention

[0005] The present invention mainly provides an auxiliary buffer support device for reducing the vibration and swaying degree of a raw coal bunker to solve the technical problems raised in the above-mentioned background technology.

[0006] The technical solution adopted by the present invention to solve the above technical problems is:

[0007] An auxiliary buffer support device for reducing the vibration and swing of a raw coal bunker comprises a coal bunker body, a buffer frame is sleeved on the bottom end of the coal bunker body, and a buffer component and a support component are sequentially arranged on the top end of the buffer frame from the inside to the outside with the coal bunker body as the axis;

[0008] The buffer assembly includes a plurality of first fixing seats fixed to the upper surface of the buffer frame and arranged around the coal bunker body, a first universal rotation mechanism fixed inside the first fixing seat, and a first gas spring connected to the execution end of the first universal rotation mechanism, an end of the first gas spring away from the first universal rotation mechanism is connected to a second universal rotation mechanism, a second fixing seat is fixed to the outer surface of the second universal rotation mechanism, and the second fixing seat is fixed to the outer surface of the coal bunker body;

[0009] The support assembly includes a first hinged seat fixed at both ends of the upper surface of the buffer frame, and a second hinged seat fixed at the other two ends of the upper surface of the buffer frame, a lifting mechanism is fixed inside the first hinged seat, a buffer mechanism is fixed inside the second hinged seat, and a lifting ring is connected to one end of the lifting mechanism and the buffer mechanism away from the buffer frame, and the lifting ring is sleeved on the outside of the top end of the coal bunker body.

[0010] Furthermore, the first universal rotation mechanism and the second universal rotation mechanism have the same structure. The first universal rotation mechanism includes a joint seat fixed inside the first fixed seat, and a ball joint inserted into the joint seat. The ball joint is fixed to the bottom end of the first gas spring. The energy storage of the first gas spring reduces the vibration of the coal bunker body in any direction. Similarly, the first gas spring adapts to the vibration of the coal bunker body in any direction through the first universal rotation mechanism.

[0011] Furthermore, the lifting mechanism includes a hydraulic rod rotatably connected to the shell of the first articulated seat via a rotating shaft, and one end of the hydraulic rod away from the first articulated seat is rotatably connected to a first articulated plate via a rotating shaft. The first articulated plate is fixed to the outer surface of the lifting ring, and the vibration of the coal bunker body is adapted to the rotation of the hydraulic rod on the first articulated seat.

[0012] Furthermore, the buffer mechanism includes a driven rod rotatably connected to the shell of the second articulated seat through a rotating shaft, and a second gas spring fixed to the driven rod at one end away from the second articulated seat, and the second gas spring is rotatably connected to the second hinge plate on both sides of the end away from the driven rod through the rotating shaft, and the second hinge plate is fixed to the outer surface of the lifting ring. The vibration generated by the coal bunker body is absorbed by the energy storage of the second gas spring. At the same time, the driven rod on the second gas spring rotates in the shell of the second articulated seat to adapt to the vibration of the coal bunker body.

[0013] Furthermore, the buffer mechanism also includes a movable plate mounted on the outer surface of the piston rod of the second gas spring, a fixed plate fixed to the outer surface of the driven rod, and a first spring located between the movable plate and the fixed plate and mounted on the outside of the driven rod. Since the first spring is provided between the movable plate and the fixed plate fixed on the outside of the driven rod, the energy stored in the first spring is utilized to assist the gas spring in further mitigating the vibration of the coal bin body.

[0014] Furthermore, third gas springs are fixed at the four top corners of the lower surface of the buffer frame, and a shock-absorbing mechanism is provided between two adjacent third gas springs on the same side. The shock-absorbing mechanism includes a lifting block fixed to the lower surface of the buffer frame, a connecting rod rotatably connected to the bottom end of the lifting block through a rotating shaft, and a sliding ring connected to the end of the connecting rod away from the lifting block through a rotating shaft, the sliding ring is inserted into the outer surface of the sliding rod, and the sliding ring is fixed between the bottom ends of two adjacent third gas springs. When the coal bin main body vibrates and drives the first fixed seat and the second fixed seat to shake, the energy storage of the third gas spring at the bottom end of the buffer frame provides buffering for the buffer frame.

[0015] Furthermore, the shock absorbing mechanism also includes a termination ring which is sleeved on the outer surface of the sliding rod and fixed to the outer surface of the bottom end of the third gas spring. A second spring is provided between the termination ring and the adjacent sliding ring. The energy stored in the second spring is utilized to assist the third gas spring in providing buffering for the buffer frame.

[0016] Furthermore, a damping mechanism is provided between the buffer assembly and the support assembly, and the damping mechanism includes a third hinged piece rotatably connected to both ends of the first gas spring through a rotating shaft, and a fourth gas spring rotatably connected to the third hinged piece through a rotating shaft, and the fourth gas springs at both ends are hinged to the hydraulic rod on one side away from the third hinged piece through the rotating shaft, and the fourth gas springs at both ends are hinged to the driven rod on one side away from the third hinged piece through the rotating shaft, and the first gas spring and the driven rod are assisted by the fourth gas spring between the first gas spring and the hydraulic rod to provide a buffering effect on the coal bunker body.

[0017] Furthermore, the inner ring surface of the lifting ring is provided with a plurality of grooves, and the inside of the grooves is provided with a third spring and a slide rod in sequence from the inside to the outside. The slide rod is extended and retracted by the third spring so that the slide rod can maintain contact with the coal bunker body.

[0018] Furthermore, a displacement sensor is fixed on the outer surface of the slide bar, and the displacement of the slide bar is detected by the displacement sensor to determine the shaking amplitude of the coal bunker body.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] Firstly, the present invention can provide suitable buffering for the vibrating coal bunker body while providing support for the coal bunker body, thereby reducing the loss of the coal bunker body. Specifically, the coal bunker body pushes the second fixed seat to move, and the second fixed seat pushes the second universal rotation mechanism to move, and the first gas spring adapts to the angle change of the coal bunker body, thereby slowing down the vibration of the coal bunker body in any direction through the energy storage of the first gas spring. In this process, since a hydraulic rod is provided at the bottom end of the lifting ring and the lifting ring is stuck on the coal bunker body, support is provided for the coal bunker body.

[0021] Secondly, the present invention can improve the buffering effect according to the vibration size of the coal bunker body, thereby extending the service life of the coal bunker body. Specifically, the hydraulic rod is extended and retracted to push the lifting ring to rise and fall until a certain degree of gap is generated between the inner ring of the lifting ring and the coal bunker body, thereby providing a suitable buffering space for the top of the coal bunker body with a smaller vibration amplitude through the gap, and the lifting ring pushes the second gas spring hinged thereon to extend and retract, thereby absorbing the vibration generated by the coal bunker body through the energy storage of the second gas spring.

The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] For examples, please refer to the attached Figure 1-8 An auxiliary buffer support device for reducing the vibration and swing of a raw coal bunker comprises a coal bunker body 10, a buffer frame 20 is sleeved on the bottom end of the coal bunker body 10, and a buffer assembly 30 and a support assembly 40 are sequentially arranged on the top end of the buffer frame 20 from the inside to the outside with the coal bunker body 10 as the axis;

[0036] The buffer assembly 30 includes a plurality of first fixing seats 31 fixed to the upper surface of the buffer frame 20 and arranged around the coal bunker body 10, a first universal rotation mechanism 32 fixed inside the first fixing seat 31, and a first gas spring 33 connected to the execution end of the first universal rotation mechanism 32, an end of the first gas spring 33 away from the first universal rotation mechanism 32 is connected to a second universal rotation mechanism 34, a second fixing seat 35 is fixed to the outer surface of the second universal rotation mechanism 34, and the second fixing seat 35 is fixed to the outer surface of the coal bunker body 10;

[0037] The support assembly 40 includes a first hinged seat 41 fixed at both ends of the upper surface of the buffer frame 20, and a second hinged seat 42 fixed at the other two ends of the upper surface of the buffer frame 20. A lifting mechanism 43 is fixed inside the first hinged seat 41, and a buffer mechanism 44 is fixed inside the second hinged seat 42. The lifting mechanism 43 and the buffer mechanism 44 are connected to a lifting ring 45 at one end away from the buffer frame 20, and the lifting ring 45 is sleeved on the outside of the top end of the coal bin body 10.

[0038] For details, please refer to the attached Figure 3 , 4 8, the first universal rotation mechanism 32 and the second universal rotation mechanism 34 have the same structure, the first universal rotation mechanism 32 includes a joint seat 321 fixed inside the first fixing seat 31, and a ball joint 322 inserted into the joint seat 321, and the ball joint 322 is fixed to the bottom end of the first gas spring 33;

[0039] It should be noted that, in the present embodiment, when the coal bunker body 10 generates lateral or longitudinal vibration, the second fixed seat 35 is pushed to be displaced by the coal bunker body 10, and the second fixed seat 35 pushes the second universal rotation mechanism 34 to be displaced. Since the second universal rotation mechanism 34 has the same structure as the first universal rotation mechanism 32, the first gas spring 33 on the ball joint 322 adapts to the angle change of the coal bunker body 10 through the rotation of the joint seat 321 on the ball joint 322, thereby reducing the vibration of the coal bunker body 10 in any direction through the energy storage of the first gas spring 33. Similarly, the first gas spring 33 adapts to the vibration of the coal bunker body 10 in any direction through the first universal rotation mechanism 32.

[0040] For details, please refer to the attached Figure 3 and 5The lifting mechanism 43 includes a hydraulic rod 431 rotatably connected to the housing of the first hinge seat 41 through a rotating shaft, and the end of the hydraulic rod 431 away from the first hinge seat 41 is rotatably connected to a first hinge plate 432 through a rotating shaft, and the first hinge plate 432 is fixed to the outer surface of the lifting ring 45. The buffer mechanism 44 includes a driven rod 441 rotatably connected to the housing of the second hinge seat 42 through a rotating shaft, and a second gas spring 442 fixed to the end of the driven rod 441 away from the second hinge seat 42 , both sides of the end of the second gas spring 442 away from the driven rod 441 are rotatably connected with a second hinge piece 443 through a rotating shaft, and the second hinge piece 443 is fixed to the outer surface of the lifting ring 45. The buffer mechanism 44 also includes a movable disk 444 sleeved on the outer surface of the piston rod of the second gas spring 442, a fixed disk 445 fixed to the outer surface of the driven rod 441, and a first spring 446 located between the movable disk 444 and the fixed disk 445 and sleeved on the outside of the driven rod 441;

[0041] It should be noted that, in this embodiment, since the hydraulic rod 431 is hinged to the lifting ring 45 through the first hinge plate 432 on the lifting ring 45, the lifting ring 45 is pushed up and down by the extension and contraction of the hydraulic rod 431. Since the bottom end of the hydraulic rod 431 is rotatably connected to the first hinge seat 41 on the upper surface of the buffer frame 20 through the rotating shaft, when the coal bunker body 10 vibrates, the hydraulic rod 431 rotates on the first hinge seat 41 to adapt to the vibration of the coal bunker body 10.

[0042] Furthermore, when the coal bunker body 10 pushes the lifting ring 45 to move due to vibration, the lifting ring 45 pushes the second gas spring 442 hinged thereon to expand and contract, so that the vibration generated by the coal bunker body 10 is absorbed by the energy storage of the second gas spring 442. At the same time, the driven rod 441 on the second gas spring 442 rotates in the housing of the second hinge seat 42 to adapt to the vibration of the coal bunker body 10.

[0043] Furthermore, when the second gas spring 442 is storing energy, the movable disk 444 on the piston rod of the second gas spring 442 moves along with the piston rod. Since a first spring 446 is provided between the movable disk 444 and a fixed disk 445 fixed to the outside of the driven rod 441, the energy stored in the first spring 446 is utilized to assist the second gas spring 442 in further slowing down the vibration of the coal bin body 10.

[0044] For details, please refer to the attached Figure 1 and 5, third gas springs 21 are fixed at the four top corners of the lower surface of the buffer frame 20, and a shock absorbing mechanism 22 is arranged between two adjacent third gas springs 21 on the same side, and the shock absorbing mechanism 22 includes a lifting block 221 fixed to the lower surface of the buffer frame 20, a connecting rod 222 rotatably connected to the bottom end of the lifting block 221 through a rotating shaft, and a sliding ring 223 connected to the end of the connecting rod 222 away from the lifting block 221 through a rotating shaft, and the sliding ring 223 is inserted into the outer surface of the sliding rod 224, and the sliding ring 223 is fixed between the bottom ends of two adjacent third gas springs 21, and the shock absorbing mechanism 22 also includes a sleeve arranged on the sliding rod 224. The rod 224 is provided with a termination ring 225 fixed to the outer surface of the bottom end of the third gas spring 21, a second spring 226 is provided between the termination ring 225 and the adjacent sliding ring 223, a damping mechanism is provided between the buffer assembly 30 and the support assembly 40, the damping mechanism includes a third hinged piece rotatably connected to both ends of the first gas spring 33 through a rotating shaft, a fourth gas spring rotatably connected to the third hinged piece through a rotating shaft, the fourth gas springs at both ends are hinged to the hydraulic rod 431 at one side away from the third hinged piece through a rotating shaft, and the fourth gas springs at the other two ends are hinged to the driven rod 441 at one side away from the third hinged piece through a rotating shaft;

[0045] It should be noted that, in this embodiment, when the coal bunker body 10 vibrates and drives the first fixing seat 31 and the second fixing seat 35 to also vibrate, the third gas spring 21 at the bottom of the buffer frame 20 stores energy to provide a buffer for the buffer frame 20.

[0046] When the buffer frame 20 vibrates in the vertical direction, the buffer frame 20 drives the lifting block 221 to move up and down, and the lifting block 221 pushes the connecting rod 222, so that the connecting rod 222 drives the sliding ring 223 to slide on the sliding rod 224, so as to prolong the transmission time of the vibration force of the buffer frame 20, thereby providing buffering for the buffer frame 20;

[0047] Furthermore, the connecting rod 222 drives the sliding ring 223 to slide on the sliding rod 224. Since a second spring 226 is provided between the sliding ring 223 and the end ring 225, the energy storage of the second spring 226 is utilized to assist the third gas spring 21 in providing buffering for the buffer frame 20.

[0048] Furthermore, when the first gas spring 33, the driven rod 441 and the hydraulic rod 431 vibrate due to the coal bunker body 10, since a fourth gas spring is provided between the first gas spring 33 and the driven rod 441, the energy storage of the fourth gas spring is utilized to extend the time of vibration force transmission, thereby assisting the first gas spring 33 and the driven rod 441 in providing a buffering effect on the coal bunker body 10. Similarly, the first gas spring 33 and the hydraulic rod 431 are also assisted by the fourth gas spring in providing a buffering effect on the coal bunker body 10.

[0049] For details, please refer to the attached Figure 1 and 6 The inner ring surface of the lifting ring 45 is provided with a plurality of grooves 451, and the interior of the grooves 451 is provided with a third spring 452 and a slide bar 453 in sequence from the inside to the outside, and a displacement sensor 454 is fixed on the outer surface of the slide bar 453;

[0050] It should be noted that, in this embodiment, when the coal bunker body 10 pushes the slide bar 453, the slide bar 453 slides inside the groove 451, thereby providing a buffer for the coal bunker body 10, and the slide bar 453 is extended and retracted by the third spring 452, so that the slide bar 453 can maintain contact with the coal bunker body 10;

[0051] Furthermore, the displacement of the slide bar 453 is detected by the displacement sensor 454, so that when the displacement sensor 454 with model number MMA7660FCR1 transmits the electrical signal with the displacement information of the slide bar 453 through its communication end to the PLC controller connected thereto, the PLC control determines the shaking amplitude of the coal bin body 10 according to whether the displacement of the slide bar 453 exceeds the set value.

[0052] The specific operation mode of the present invention is as follows:

[0053] When the coal bunker body 10 pushes the slide bar 453 due to vibration, the slide bar 453 slides inside the groove 451, thereby providing a buffer for the coal bunker body 10. The slide bar 453 is extended and retracted by the third spring 452, so that the slide bar 453 can maintain contact with the coal bunker body 10. The displacement of the slide bar 453 is detected by the displacement sensor 454, so that the displacement sensor 454 with the model number of MMA7660FCR1 transmits the electrical signal with the displacement information of the slide bar 453 to the PLC controller connected thereto through its communication terminal. The PLC controller determines the vibration amplitude of the coal bunker body 10 according to whether the displacement of the slide bar 453 exceeds the set value.

[0054] When the vibration of the coal bunker body 10 is small, the second fixed seat 35 is pushed by the coal bunker body 10 to move, and the second fixed seat 35 pushes the second universal rotation mechanism 34 to move. Since the second universal rotation mechanism 34 has the same structure as the first universal rotation mechanism 32, the first gas spring 33 on the ball joint 322 adapts to the angle change of the coal bunker body 10 through the rotation of the joint seat 321 on the ball joint 322, so that the vibration of the coal bunker body 10 in any direction is slowed down by the energy storage of the first gas spring 33. Similarly, the first gas spring 33 adapts to the vibration of the coal bunker body 10 in any direction through the first universal rotation mechanism 32.

[0055] When the coal bunker body 10 vibrates greatly, since the hydraulic rod 431 is hinged to the lifting ring 45 through the first hinge plate 432 on the lifting ring 45, the lifting ring 45 is pushed to be lifted and lowered by the extension and retraction of the hydraulic rod 431 until a certain degree of gap is generated between the inner ring of the lifting ring 45 and the coal bunker body 10, thereby providing a suitable buffer space for the top of the coal bunker body 10 with a smaller vibration amplitude through the gap, and the lifting ring 45 pushes the second gas spring 442 hinged thereon to extend and retract, thereby absorbing the vibration generated by the coal bunker body 10 through the energy storage of the second gas spring 442.

[0056] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
