Description

Technical Field

[0001] The present invention mainly relates to the technical field of coal transportation, and in particular to an automatic lifting vibration device for loosening materials in a raw coal bin. Background Art

[0002] Coal-fired power plants mostly use raw coal bunkers to store coal between coal feeders. During the transportation of raw coal, a vibration device is often required to vibrate the raw coal bunker to prevent it from being blocked.

[0003] According to the patent document with application number CN202022781214.0, a device for preventing and dredging the raw coal bunker of a thermal power plant is provided. It can be known that the anti-blocking device includes an airflow jet layer and a pneumatic hammer layer. The airflow jet layer is provided with several layers and the airflow jet layer is used to spray high-pressure airflow into the inner cavity of the raw coal bunker. The pneumatic hammer layer is provided with several layers and the pneumatic hammer layer is provided on the outer wall of the raw coal bunker. The airflow jet layer and / or pneumatic hammer layer are provided between the inlet and outlet of the raw coal bunker. The anti-blocking device dredges the raw coal bunker as a whole, ensures smooth coal flow in each section of the raw coal bunker, and ensures the normal operation of the coal conveying of the coal feeder. The overall solution 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, which greatly broadens the adaptability of coal types and improves the level of coal utilization.

[0004] The above-mentioned anti-blocking device unclogs the entire raw coal bin to ensure smooth coal flow in each section of the raw coal bin, but the pneumatic hammer layer set by the above-mentioned anti-blocking device is difficult to move up and down, resulting in the inability to adjust the pneumatic hammer to deal with different blocked coal ends, affecting the dredging effect of the vibration device. Summary of the Invention

[0005] The present invention mainly provides an automatic lifting vibration device for loosening materials in a raw coal bin to solve the technical problems raised in the above background technology.

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

[0007] An automatic lifting vibration device for loosening raw coal bunker materials, comprising a coal bunker body, a lifting assembly provided on the outer top of the coal bunker body, and a rapping assembly connected to a driving end of the lifting assembly;

[0008] The lifting assembly includes a support ring fixed to the outer surface of the coal bunker body, an opening provided on the support ring housing, and a hoist provided at the top end of the opening and fixed to the upper surface of the support ring;

[0009] The rapping assembly includes a connecting mechanism connected to the execution end of the hoist, a lifting ring connected to the execution end of the connecting mechanism, and a rapping mechanism provided at the top of the lifting ring and symmetrically arranged, and a fixing mechanism is provided between the rapping mechanism and the adjacent connecting mechanism;

[0010] The rapping mechanism includes a translation component arranged at the top of the lifting ring, a translation block connected to the execution end of the translation component, and a rapping air hammer arranged through the translation block. A first electromagnet is fixed to the bottom end of the translation block.

[0011] Furthermore, the connecting mechanism includes a buckle head fixed to the upper surface of the support ring, and a steel wire rope connected to the buckle head. The end of the steel wire rope away from the buckle head passes through the opening and is connected to the winch. The buckle head is pulled by the steel wire rope to drive the lifting ring at the bottom end of the buckle head to rise and fall.

[0012] Furthermore, the translation component includes a screw rod connected to both ends of the translation block through a nut and arranged through the translation block, a bearing seat rotatably connected to one end of the screw rod and fixed to the upper surface of the lifting ring, and a reducer rotatably connected to the other end of the lifting ring and fixed to the outer surface of the lifting ring. The input shaft of the reducer is connected to a motor. Since the screw rod and the translation block are connected through a nut, the translation block converts the rotational motion of the screw rod into its own linear motion, so as to drive the vibrating air hammer inserted in the translation block to move.

[0013] Furthermore, the rapping mechanism also includes an infrared rangefinder fixed to the top of one end of the rapping air hammer close to the coal bin body. The rapping air hammer measures its distance from the coal bin body through the infrared rangefinder thereon, so as to adjust the hammer head of the rapping air hammer to a distance that can contact the coal bin body.

[0014] Furthermore, the rapping mechanism also includes a spring sleeved on the outside of the screw rod. When the translation block vibrates due to the rapping air hammer hitting the coal bin body, the spring absorbs the vibration to improve the stability of the rapping air hammer hitting the coal bin body.

[0015] Furthermore, the fixing mechanism includes an articulated seat fixed to the upper and lower surfaces of the support ring, a connecting rod rotatably connected to the articulated seat via a rotating shaft, and a magnetic component provided at one end of the connecting rod away from the articulated seat. By rotating the connecting rod on the articulated seat, the connecting rod can stick the magnetic component toward the coal bin body to complete the fixation of the connecting rod on the coal bin body.

[0016] Furthermore, a groove is provided at one end of the connecting rod near the hinged seat, and a torsion spring is provided inside the groove coaxially with the connecting rod. The torsion spring is accommodated by the groove on the connecting rod, and the energy stored in the torsion spring pushes the connecting rod coaxially therewith to automatically approach the coal bin body.

[0017] Furthermore, the magnetic attraction component includes a first joint seat fixed to the surface of the connecting rod on the side close to the coal bin main body, and a second joint seat provided on the side of the first joint seat away from the lifting ring and fixed on the connecting rod housing. Ball joints are inserted into the first joint seat and the second joint seat. A second electromagnet is fixed to the end of the ball joint close to the coal bin main body. When the connecting rod automatically approaches the coal bin main body, the ball joint rotates on the first joint seat and the second joint seat on the connecting rod, so that the second electromagnet on the ball joint can adapt to the angle change of the outer surface of the coal bin main body.

[0018] Furthermore, the length of the first joint seat diameter is greater than the length of the second joint seat diameter. Since the length of the first joint seat diameter is greater than the length of the second joint seat diameter, the second electromagnet at the bottom can adapt to the outer wall of the coal bin body.

[0019] Furthermore, a coal flow detector is fixed on the inner wall surface of the coal bunker body, and the raw coal in the coal bunker body is measured by the coal flow detector model MHAA to transmit an electrical model with coal blockage conditions to the PLC controller.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] Firstly, the present invention can drive the vibrating air hammer to rise and fall stably to adjust the vibrating air hammer so that the vibrating air hammer can reach the coal blockage in the coal bunker. Specifically, the winch reels in and releases the steel wire rope wrapped thereon to drive the lifting ring at the bottom end of the buckle head to rise and fall. After the vibrating mechanism is driven to move to the coal blockage position by the lifting ring, the vibrating air hammer is driven to move by the motor until the hammer head of the vibrating air hammer is adjusted to a distance that allows it to contact the main body of the coal bunker, thereby effectively hitting the coal blockage position of the main body of the coal bunker through the vibrating air hammer.

[0022] Secondly, when the present invention is used to vibrate the coal-blocking position of the coal bunker main body, the connecting rod will stick the magnetic component to the coal bunker main body, and the ball joint will rotate on the first joint seat and the second joint seat on the connecting rod, so that the second electromagnet on the ball joint can adapt to the angle change of the outer surface of the coal bunker main body, so that after the second electromagnet is energized, the connecting rod is fixed on the coal bunker main body, thereby using the fixed connecting rod to provide stable support for the lifting ring.

[0023] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0034] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which the present invention pertains. The terminology used herein 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 of the related listed items.

[0036] For example, please refer to the attached Figure 1-8 , an automatic lifting vibration device for loosening raw coal bunker materials, comprising a coal bunker body 10, a lifting assembly 20 is provided at the outer top end of the coal bunker body 10, and a rapping assembly 30 is connected to the driving end of the lifting assembly 20;

[0037] The lifting assembly 20 includes a support ring 21 fixed to the outer surface of the coal bunker body 10, an opening 22 provided on the shell of the support ring 21, and a hoist 23 provided at the top of the opening 22 and fixed to the upper surface of the support ring 21;

[0038] The rapping assembly 30 includes a connecting mechanism 31 connected to the execution end of the hoist 23, a lifting ring 32 connected to the execution end of the connecting mechanism 31, and a rapping mechanism 33 symmetrically arranged at the top of the lifting ring 32, and a fixing mechanism 34 is provided between the rapping mechanism 33 and the adjacent connecting mechanism 31;

[0039] The rapping mechanism 33 includes a translation component 331 provided at the top of the lifting ring 32, a translation block 332 connected to the execution end of the translation component 331, and a rapping air hammer 334 provided through the translation block 332. A first electromagnet 333 is fixed to the bottom end of the translation block 332.

[0040] For details, please refer to the attached Figure 1 and 2 The connecting mechanism 31 includes a buckle head 311 fixed to the upper surface of the support ring 21, and a steel wire rope 312 connected to the buckle head 311. The end of the steel wire rope 312 away from the buckle head 311 passes through the opening 22 and is connected to the winch 23.

[0041] It should be noted that, in this embodiment, when the winch 23 performs the rope-reeling and rope-releasing actions on the steel wire rope 312 wound thereon, the buckle head 311 is pulled by the steel wire rope 312 to drive the lifting ring 32 at the bottom end of the buckle head 311 to rise and fall.

[0042] For details, please refer to the attached Figure 2 、 3 and 6, the translation component 331 includes a screw rod 3311 connected to both ends of the translation block 332 through a nut and arranged to pass through the translation block 332, a bearing seat 3312 rotatably connected to one end of the screw rod 3311 and fixed to the upper surface of the lifting ring 32, and a reducer 3313 rotatably connected to the other end of the lifting ring 32 and fixed to the outer surface of the lifting ring 32, the input shaft of the reducer 3313 is connected to the motor 3314, the rapping mechanism 33 also includes an infrared rangefinder 335 fixed to the top of one end of the rapping air hammer 334 near the coal bunker body 10, and the rapping mechanism 33 also includes a spring 336 sleeved on the outside of the screw rod 3311;

[0043] It should be noted that, in this embodiment, the output shaft of the motor 3314 drives the reducer 3313 to operate, and the reducer 3313 drives the screw rod 3311 connected to its output shaft to rotate. Since the screw rod 3311 is connected to the translation block 332 via a nut, the translation block 332 converts the rotational motion of the screw rod 3311 into its own linear motion, thereby driving the rapping hammer 334 inserted on the translation block 332 to move;

[0044] Furthermore, the rapping hammer 334 measures the distance from the coal bunker body 10 through the infrared rangefinder 335 thereon, so as to adjust the hammer head of the rapping hammer 334 to a distance at which the hammer head can contact the coal bunker body 10, so that the rapping hammer 334 can effectively hit the coal bunker body 10;

[0045] Furthermore, since two springs 336 are provided on the outside of the screw rod 3311, the springs 336 are respectively located on both sides of the translation block 332, so that when the translation block 332 vibrates due to the vibration of the rapping air hammer 334 hitting the coal bin body 10, the vibration is absorbed by the spring 336 to improve the stability of the rapping air hammer 334 hitting the coal bin body 10.

[0046] For details, please refer to the attached Figure 2 、 6and 8, the fixing mechanism 34 includes an articulated seat 341 fixed to the upper and lower surfaces of the support ring 21, a connecting rod 342 rotatably connected to the articulated seat 341 through a rotating shaft, and a magnetic component 343 provided at one end of the connecting rod 342 away from the articulated seat 341, a groove 344 is provided at one end of the connecting rod 342 close to the articulated seat 341, a torsion spring 345 is provided coaxially with the connecting rod 342 inside the groove 344, and the magnetic component 343 includes a connecting rod 342 fixed to the coal A first joint seat 3431 is provided on one side of the coal bunker body 10, and a second joint seat 3433 is provided on the side of the first joint seat 3431 away from the lifting ring 32 and fixed to the housing of the connecting rod 342. A ball joint 3432 is inserted into each of the first joint seat 3431 and the second joint seat 3433. A second electromagnet 3434 is fixed to the end of the ball joint 3432 close to the coal bunker body 10. The diameter of the first joint seat 3431 is greater than the diameter of the second joint seat 3433.

[0047] It should be noted that, in this embodiment, the connecting rod 342 rotates on the hinge seat 341 so that the connecting rod 342 can stick the magnetic component 343 toward the coal bunker body 10, thereby completing the fixing of the connecting rod 342 on the coal bunker body 10, thereby utilizing the fixed connecting rod 342 to provide stable support for the lifting ring 32;

[0048] Furthermore, the groove 344 on the connecting rod 342 accommodates the torsion spring 345, and the energy stored in the torsion spring 345 pushes the connecting rod 342 coaxially arranged therewith to automatically approach the coal bunker body 10;

[0049] Furthermore, when the connecting rod 342 automatically approaches the coal bunker body 10, the ball joint 3432 rotates on the first joint seat 3431 and the second joint seat 3433 on the connecting rod 342, so that the second electromagnet 3434 on the ball joint 3432 can adapt to the angle change of the outer surface of the coal bunker body 10;

[0050] Furthermore, since the diameter of the first joint seat 3431 is greater than the diameter of the second joint seat 3433 , the second electromagnet 3434 at the bottom can adapt to the outer wall of the coal bunker body 10 ;

[0051] Furthermore, the raw coal in the coal bunker body 10 is measured by a coal flow detector 11 with the model number MH7143AA10, and an electrical model indicating the coal blockage is transmitted to the communication terminal of the PLC controller, so that the motor 3314 connected thereto is controlled by the communication terminal of the PLC controller, thereby starting the rapping mechanism 33 for rapping.

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

[0053] When the raw coal enters through the coal inlet at the top of the coal bunker body 10, but is blocked in the coal bunker body 10 and is difficult to be discharged from the coal outlet at the bottom of the coal bunker body 10, the hoist 23 performs rope-reeling and rope-releasing actions on the wire rope 312 wound thereon, and pulls the buckle head 311 through the wire rope 312 to drive the lifting ring 32 at the bottom of the buckle head 311 to move up and down, and after the lifting ring 32 drives the vibrating mechanism 33 to move to the coal blocking position, the output shaft of the motor 3314 drives the reducer 3313 to operate, and the reducer 3313 drives the screw rod 3311 connected to its output shaft to rotate, and the winch 23 performs rope-reeling and rope-releasing actions on the wire rope 312. The screw rod 3311 and the translation block 332 are connected by a nut, so that the translation block 332 converts the rotational motion of the screw rod 3311 into its own linear motion, thereby driving the rapping air hammer 334 inserted on the translation block 332 to move until the hammer head of the rapping air hammer 334 is adjusted to a distance that can contact the coal bunker body 10, thereby effectively hitting the coal blocking position of the coal bunker body 10 through the rapping air hammer 334. During this process, the first electromagnet 333 on the translation block 332 is energized to make the translation block 332 adsorbed on the lifting ring 32, thereby improving the stability of the rapping air hammer 334 during vibration;

[0054] When the coal-blocking position of the coal bin main body 10 is vibrated, the connecting rod 342 uses the energy stored in the torsion spring 345 thereon to push the connecting rod 342 to rotate on the hinge seat 341, so that the connecting rod 342 sticks the magnetic component 343 to the coal bin main body 10, and the ball joint 3432 rotates on the first joint seat 3431 and the second joint seat 3433 on the connecting rod 342, so that the second electromagnet 3434 on the ball joint 3432 can adapt to the angle change of the outer surface of the coal bin main body 10, so that after the second electromagnet 3434 is energized, the connecting rod 342 is fixed on the coal bin main body 10, thereby using the fixed connecting rod 342 to provide stable support for the lifting ring 32.

[0055] The above description of the present invention is exemplified in conjunction 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 using 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 scope of protection of the present invention.
