Description

Technical Field

[0001] This utility model relates to the field of air cannon technology, specifically an air cannon for clearing coal blockages in raw coal bunkers. Background Technology

[0002] Coal is the primary fuel for thermal power plants. Due to limited storage space, most coal is stored in the open, resulting in high moisture content. During transportation, coal often arches and adheres in the silo, and coal blockages or interruptions frequently occur at pipe bends and branch points. To improve the flowability of materials in the silo and pipes and quickly and safely eliminate these phenomena, air cannons are usually installed.

[0003] Currently, most existing air cannons are fixed by welding. During use, the outlet position of the air cannon cannot be quickly matched with the position of the pipe, resulting in a decrease in installation efficiency. At the same time, it is difficult to achieve a certain degree of shock absorption during use, which can easily cause damage to its internal parts. Utility Model Content

[0004] To address the aforementioned issues, this application provides a universal air cannon for clearing coal blockages in raw coal bunkers. This solves the problems of existing air cannons, which use a fixed installation method, making it impossible to quickly match the installation pipeline position, resulting in low installation efficiency, and also preventing vibration damping during use.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: an air cannon for clearing coal blockage in raw coal bunkers, including an air cannon body and a lifting plate fixedly installed at the lower end of the air cannon body, wherein an adjustment device is hinged to the lower end of the lifting plate.

[0006] The adjustment device includes a base plate, which is horizontally positioned below the lifting plate. Rubber bases are arranged in a matrix on the lower end face of the base plate.

Adjustment components are screwed into the threaded holes. Limiting components are provided on the side of the support components. The limiting components and support components are installed together. Shock-absorbing components are evenly arranged on the upper end face of the base plate, directly below the lifting plate.

[0007] Preferably, the lower end face of the lifting plate is uniformly provided with a first buffer plate.

[0008] Preferably, the support assembly includes a slide rod, a slide rod is horizontally fixedly installed in the rectangular slide groove near the bottom, a rectangular slider is sleeved on the slide rod, a compression spring is sleeved on the slide rod between the rectangular slider and the rectangular slide groove, a support plate is hinged to the upper end of the rectangular slider, and the upper end of the support plate is hinged to the lower end face of the lifting plate.

[0029] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0030] like Figures 1-4 As shown, this utility model embodiment provides a general-purpose air cannon for clearing coal blockage in a raw coal bunker, including an air cannon body 1 and a lifting plate 2 fixedly installed at the lower end of the air cannon body 1. The lower end surface of the lifting plate 2 is uniformly provided with a first buffer plate 21, and the lower end of the lifting plate 2 is hinged with an adjustment device 3.

[0031] The adjustment device 3 includes a base plate 31, which is horizontally arranged below the lifting plate 2. Rubber bases 32 are arranged in a matrix on the lower end face of the base plate 31. Rectangular slide grooves 33 are arranged in a matrix on the upper end face of the base plate 31. A support component 34 is arranged in the rectangular slide groove 33. The upper end of the support component 34 is hinged to the lower end face of the lifting plate 2. Threaded holes are opened on the opposite side wall of the rectangular slide groove 33. Adjustment components 35 are screwed into the threaded holes. Limiting components 36 are arranged on the side of the support component 34. The limiting components 36 and the support component 34 are installed together. Shock-absorbing components 37 are evenly arranged on the upper end face of the base plate 31 and located directly below the lifting plate 2.

[0032] The support assembly 34 includes a slide rod 341. The slide rod 341 is horizontally fixedly installed in the rectangular slide groove 33 near the bottom. A rectangular slider 342 is sleeved on the slide rod 341. A compression spring 343 is sleeved on the slide rod 341 between the rectangular slider 342 and the rectangular slide groove 33. A wear-resistant protrusion 3421 is fixedly installed on the side wall of the rectangular slider 342 away from the compression spring 343. A support plate 344 is hinged to the upper end of the rectangular slider 342. The upper end of the support plate 344 is hinged to the lower end face of the lifting plate 2.

[0033] The adjustment component 35 includes a "T"-shaped threaded rod 351. A threaded hole is provided on the side wall of the rectangular slide groove 33 opposite to the wear-resistant protrusion 3421. The "T"-shaped threaded rod 351 is screwed into the threaded hole. A handle 352 is fixedly provided on the side wall of the "T"-shaped threaded rod 351 away from the wear-resistant protrusion 3421.

[0034] In practice, the air cannon for clearing coal blockage in the raw coal bunker is first placed on a flat surface by hand. Then, the handle 352 is held and the "T"-shaped threaded rod 351 is rotated. The "T"-shaped threaded rod 351 will rotate and move towards the rectangular slider 342. Through the action of the "T"-shaped threaded rod 351 on the wear-resistant protrusion 3421, the rectangular slider 342 moves towards the center of the base plate 31. At this time, the compression spring 343 is compressed. Under the action of the support plate 344, the lifting plate 2 will move upward, thereby changing the horizontal height of the air cannon body 1. In this way, the outlet position of the air cannon body 1 can be quickly matched with the pipe position, thereby improving the installation efficiency.

[0035] The limiting component 36 includes a socket 361. A limiting hole is provided on the side wall of the rectangular slider 342. The socket 361 is provided on the side wall of the rectangular slide groove 33 corresponding to the limiting hole. A "T"-shaped pin 362 is inserted into the socket 361 and extends into the limiting hole. A semi-circular pull ring 363 is fixedly installed on the side wall of the "T"-shaped pin 362 away from the limiting hole.

[0036] In specific operation, once the height of the air cannon body 1 is determined, the "T"-shaped pin 362 is inserted into the insertion hole 361 by manually holding the semi-circular pull ring 363 and inserting its end into the limiting hole, thereby limiting and fixing the rectangular slider 342. This further ensures the stability of the support component 34.

[0037] The shock absorption component 37 includes a cylindrical body 371. The cylindrical bodies 371 are evenly arranged on the upper surface of the base plate 31. A shock absorption spring 372 is fixedly installed at the bottom of the cylindrical body 371. A second buffer plate 373 is fixedly connected to the upper end of the shock absorption spring 372. The upper end of the second buffer plate 373 abuts against the first buffer plate 21. Both the first buffer plate 21 and the second buffer plate 373 are made of flexible material.

[0038] In actual operation, during the use of the air cannon body 1, the shock-absorbing spring 372 can ensure that the second buffer plate 373 is always in contact with the first buffer plate 21. If the air cannon body 1 vibrates, the shock-absorbing spring 372 can be compressed back and forth, thereby playing a shock-absorbing and buffering role on the air cannon body 1. Together with the role of the first buffer plate 21 and the second buffer plate 373, damage to the internal components of the air cannon body 1 can be avoided.

[0039] Working principle: First, the air cannon for clearing coal blockage in the raw coal bunker is placed on a flat surface by manual labor. Then, the "T"-shaped pin 362 is pulled out of the insertion hole 361 by manual labor by holding the semi-circular pull ring 363. At this time, the "T"-shaped pin 362 no longer limits the rectangular slider 342. Then, the "T"-shaped threaded rod 351 is rotated by manual labor by holding the handle 352 and rotating. The "T"-shaped threaded rod 351 will move towards the rectangular slider 342 while rotating. Through the action of the wear-resistant protrusion 3421 driven by the "T"-shaped threaded rod 351, the rectangular slider 342 moves towards the middle of the base plate 31. At this time, the compression spring 343 is compressed. Under the action of the support plate 344, the lifting plate 2 will move upward, thereby changing the horizontal height of the air cannon body 1. In this way, the outlet position of the air cannon body 1 can be quickly matched with the pipe position, thereby improving the installation efficiency.

[0040] Once the height of the air cannon body 1 is determined, the "T"-shaped pin 362 is inserted into the insertion hole 361 by manually holding the semi-circular pull ring 363 and inserting its end into the limiting hole, thereby limiting and fixing the rectangular slider 342. This further ensures the stability of the support component 34.

[0041] During the use of the air cannon body 1, the shock-absorbing spring 372 can ensure that the second buffer plate 373 is always in contact with the first buffer plate 21. If the air cannon body 1 vibrates, the shock-absorbing spring 372 can be compressed back and forth, thereby playing a shock-absorbing and buffering role on the air cannon body 1. Together with the role of the first buffer plate 21 and the second buffer plate 373, damage to the internal components of the air cannon body 1 can be avoided.

[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 scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
