[0031] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0032] Example 1

[0033] like Figures 1-4 As shown, an online unblocking device for a coal chutes at intersections in a plant coal transportation system includes a drive unit 2, a rotating component 3, an unblocking component 4, and a protective device 5. The drive unit 2 is fixedly connected to the coal chutes, and the output end of the drive unit 2 is provided with the rotating component 3. One end of the unblocking component 4 is fixedly connected to the rotating component 3, and its middle part is wound around the rotating component 3. The protective device 5 is located outside the drive unit 2, the rotating component 3, and the unblocking component 4. A guide port 51 is opened on one side of the protective device 5, and an interface is opened on the coal chutes. The guide port 51 is located at the interface, and the other end of the unblocking component 4 passes through the guide port 51 and extends into the coal chutes through the interface.

[0034] Specifically, when coal enters the coal chute, the drive device 2 drives the rotating component 3 to rotate, which in turn causes the unblocking component 4 to extend or retract. When the unblocking component 4 extends, one end of it enters the coal chute and extends downwards along the inner wall of the chute. The unblocking component 4 scrapes against the inner wall of the coal chute, causing the coal slag adhering to the inner wall to detach and fall into the chute, along with other coal pieces. Once the inner wall of the coal chute is cleaned, the extended end of the unblocking component 4 retracts and winds back onto the rotating component 3.

[0035] like Figures 1-4 As shown, a guide plate 52 is also provided at the inlet 51. The guide plate 52 extends into the coal chutes and is set downward along the inner wall of the coal chutes. The other end of the unblocking component 4 is located between the guide plate 52 and the inner wall of the coal chutes.

[0036] Specifically, one end of the unblocking component 4 extends into the coal chute along the downward direction of the guide plate 52.

[0037] like Figures 1-4 As shown, the drive device 2 is a drive motor, which is a forward and reverse rotating motor.

[0038] Specifically, the driving motor is a reversible motor, which realizes the storage or release of the clearing block 4. In the embodiment, the driving device 2 is a driving motor, and alternatively, the driving device 2 can also be other driving structures with the functions of forward rotation and reverse rotation.

[0039] As shown in Figures 1-4 , the rotating member 3 is a reel, and one end of the clearing block 4 is fixedly arranged on the reel, and the output end of the driving motor is fixedly connected to one end of the reel.

[0040] Specifically, one end of the clearing block 4 is fixedly arranged on the reel, and the other end is wound on the reel, and the reel is driven to rotate by the output end of the driving motor, so that the clearing block 4 on the reel is stored or released.

[0041] As shown in Figures 1-4 , the driving motor is further provided with a controller 6, and the controller 6 is electrically connected to the driving motor.

[0042] Specifically, the controller 6 controls the forward rotation or reverse rotation of the driving motor, and the rotation time of the driving motor in the forward rotation or reverse rotation can be adjusted according to the situation on site, so as to realize the clearing work in the coal chute.

[0043] In the embodiment, the technology of the controller 6 controlling the driving motor belongs to the prior art, and will not be described here.

[0044] As shown in Figures 1-4 , the reel is further provided with a limiting member 31, and the limiting member 31 is slidingly arranged at both ends of the reel. The two ends of the limiting member 31 move towards or away from each other along the length direction of the reel, and the limiting member 31 is electrically connected to the controller 6.

[0045] Specifically, the bases 311 at both ends of the limiting member 31 are sleeved on the reel, and the limiting member 31 is further provided with a card 312 on the base 311. When the clearing block 4 needs to be inserted into the coal chute, the bases 311 at both ends of the limiting member 31 move towards both ends of the reel, and the card 312 on the base 311 moves away from the clearing block 4; when the clearing block 4 needs to be stored, the bases 311 at both ends of the limiting member 31 move away from both ends of the reel, and the card 312 on the base 311 clamps the two sides of the clearing block 4, so as to fix the clearing block 4, so that the clearing block 4 cannot be wound again. The two ends of the limiting member 31 clamp the clearing block 4, which prevents the clearing block 4 from being completely stored in the protection device 5, so that the clearing block 4 cannot be inserted into the coal chute from the guide opening 51.

[0046] In the embodiment, the technology of the controller 6 controlling the limiting member 31 belongs to the prior art, and will not be described here.

[0047] As shown in Figures 1-4 , the inductor 7 is arranged in the coal chute, and the inductor 7 is electrically connected to the controller 6.

[0048] Specifically, the inductor 7 is arranged in the coal falling pipe, and the inductor 7 can sense the falling of the coal blocks in the coal falling pipe, so as to transmit the signal of the falling of the coal blocks to the controller 6, and the controller 6 controls the driving motor, and the driving motor drives the reel to rotate forward or reversely, so as to store or release the clearing member 4.

[0049] In the embodiment, the technology that the inductor 7 transmits the signal to the controller 6 belongs to the prior art, and will not be described here.

[0050] As shown in the figure, the detection device 1 is arranged in the coal falling pipe, and the detection device 1 is electrically connected to the controller 6. Figures 1-4

[0051] Specifically, the detection device 1 is used to detect whether the coal falling pipe is blocked, and a warning is given when the pipe is blocked, so as to remind the workers to clean the pipe in time.

[0052] As shown in the figure, the clearing member 4 is a scraper, and the scraper is an elastic member. Figures 1-4 Specifically, the clearing member 4 is made into a scraper, and the scraper is attached to the inner wall of the coal falling pipe to scrape the inner wall of the coal falling pipe, so that the coal residue adhered to the inner wall of the coal falling pipe falls into the pipe and is transported together with other coal blocks in the pipe. In the embodiment, the material of the scraper is stainless steel. Since the scraper has a certain rigidity, the scraper also has a certain elastic force, which can effectively attach to the inside of the coal falling pipe. Alternatively, the clearing member 4 can also be a structure member with scraping function.

[0053]

[0054] As shown in the figure, the inside of the protection device 5 is also fixedly provided with a support 53, and the driving device 2 is arranged on the support 53, and the rotating member 3 is rotatably connected to the inside of the protection device 5 away from the driving device 2. Figures 1-4

[0055] Specifically, the support 53 is fixedly arranged in the inside of the protection device 5, and the driving device 2 is arranged on the support 53, so that the driving device 2 is stable in the protection device 5. At the same time, one end of the rotating member 3 is rotatably connected to the inside of the protection device 5, and the rotating member 3 is fixed with the protection device 5, so as to prevent the rotating member 3 from being unstable under the driving of the driving device 2, avoid danger during cleaning, and improve the safety of the cleaning operation. In the embodiment, the edge of the protection device 5 is welded to the outside of the coal falling pipe, and is fixed with the coal falling pipe.

[0056] ​​​The beneficial effect of the embodiment is that: by setting the unblocking device in the coal falling pipe, when the coal blocks enter the coal falling pipe, the driving device 2 drives the rotating piece 3 to rotate, and the rotating piece 3 drives the unblocking piece 4 to extend or contract. When the unblocking piece 4 extends, one end of the unblocking piece 4 extends into the coal falling pipe and extends downward along the inner wall of the coal falling pipe. The inner wall of the coal falling pipe is scraped by the unblocking piece 4, so that the coal dregs adhered to the inner wall of the coal falling pipe fall off the inner wall of the coal falling pipe and fall into the pipe together with other coal blocks in the pipe. When the inner wall of the coal falling pipe is cleaned, the end of the unblocking piece 4 extending out is retracted and wound on the rotating piece 3. By the device, the coal falling pipe is cleaned in advance, so that the cross coal falling pipe is prevented from being blocked, the production reduction and shutdown caused by the shutdown of the coal conveying system are prevented, online unblocking is realized, the danger in manual unblocking is avoided, and the safety in the unblocking operation is improved.

[0057] The working process of the embodiment is as follows: in the embodiment, after the inlet tee joint of the coal falling pipe is cut to the other side, online unblocking is started after a delay of sixty seconds, and the machine is stopped after two minutes of operation. The driving motor drives the rotating piece 3 to rotate, one end of the unblocking piece 4 extends into the coal falling pipe from the interface between the guide opening 51 and the coal falling pipe, and the unblocking piece 4 extending into the coal falling pipe extends downward along the inner wall of the coal falling pipe to scrape and remove the coal dregs adhered to the inner wall of the coal falling pipe. When the coal dregs are removed, the driving motor drives the rotating piece 3 to rotate, and one end of the unblocking piece 4 enters the protection device 5 from the guide opening 51. Then, the limiting piece 31 is slid to clamp the two ends of the unblocking piece 4 on the reel, and the other end of the unblocking piece 4 is reserved in the guide opening 51 for the next time of unblocking. In the embodiment, the starting time and the operation time of the driving motor can be set according to the site conditions.
