Description

Technical Field

[0001] The present application relates to the technical field of coal bunker dredging, and in particular to a coal bunker unblocking device. Background Art

[0002] The bottom coal bunker is mainly used for temporary storage of underground coal. It is an important transfer chamber in the process of transporting underground coal to the ground. When a large vertical cylindrical coal bunker is used, its discharge port is indirectly connected to the skip loading chamber through the coal feeder chamber.

[0003] However, large pieces of gangue often get stuck at the discharge port of the coal bunker at the bottom of the mine. After the blockage, the personnel on duty must first shut down and lock the coal feeder, then shovel the coal on the coal feeder, and finally enter the coal feeder chamber for processing. This not only takes a long time and affects production, but also when personnel enter the coal feeder to clear the large pieces of gangue, the raw coal in the coal bunker may burst out and cause personal injury. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a coal bunker blockage clearing device, which can solve the technical problems raised by the background technology.

[0005] An embodiment of the present application provides a coal bunker unblocking device, including a hanger, wherein the hanger is provided with a lifting rope, one end of the lifting rope is connected to the upper part of the hanger, and the other end of the lifting rope is connected to a lifting ring, in which a pneumatic pick is inserted.

[0006] Furthermore, the hanger includes a first horizontal base frame, a second horizontal base frame and a vertical frame, and the first horizontal base frame and the second horizontal base frame are symmetrically fixed to the bottom of the vertical frame.

[0007] Furthermore, a first support rod is fixedly provided between the first horizontal base frame and the vertical frame, and a second support rod is fixedly provided between the second horizontal base frame and the vertical frame.

[0008] Furthermore, two of the first support rods and two of the second support rods are provided, and the two first support rods are symmetrically arranged, and the two second support rods are symmetrically arranged.

[0009] Furthermore, a connecting ring is fixedly provided at the middle position of the upper part of the stand, and one end of the suspension rope is tied to the connecting ring.

[0010] Furthermore, the inner ring of the hanging ring is provided with a rubber ring.

[0011] Furthermore, the length of the pneumatic pick head is 1.5 meters to 2.5 meters.

[0012] Beneficial effects of the utility model:

[0013] The utility model inserts a pneumatic pick into a lifting ring, and supports the pneumatic pick by hanging it through the cooperation of a hanger, a lifting rope and the lifting ring, and utilizes the pneumatic pick to clear a blocked coal bunker discharge port, which is quick and efficient, saves time in clearing the blockage, and ensures production. The hanger is placed at the coal feeder chamber opening, and personnel on duty work outside the coal feeder chamber opening, and there is no need for personnel to enter the coal feeder chamber opening for cleaning, thereby avoiding raw coal in the coal bunker from gushing out and causing personal injury after large pieces of gangue are cleared.

[0028] like Figure 1-4As shown, the present application provides a coal bunker blockage clearing device, including a hanger 1, on which a hanging rope 2 is provided, one end of the hanging rope 2 is connected to the upper part of the hanger 1, and the other end of the hanging rope 2 is connected to a hanging ring 3, in which a pneumatic pick 4 is inserted. The hanger 1 is placed at the outlet of the coal feeder chamber 8, and the coal feeder 9 is located inside the hanger 1. When gangue is blocked at the discharge port of the coal bunker 7, the personnel on duty insert the pneumatic pick 4 into the hanging ring 3, and use the pneumatic pick 4 to clear the blocked discharge port of the coal bunker 7, which is fast and efficient and saves time for clearing the blockage. The pneumatic pick 4 is suspended and supported by the cooperation of the hanger 1, the hanging rope 2 and the hanging ring 3, which reduces the weight of the personnel holding the pneumatic pick 4, and pulls the pneumatic pick 4 out of the hanging ring 3. There is no need for personnel to enter the outlet of the coal feeder chamber 8 for cleaning, which avoids the raw coal in the coal bunker 7 from gushing out after large pieces of gangue are cleared, causing personal injury. After the cleaning is completed,

[0029] like Figure 1 and Figure 3 As shown, the hanger 1 includes a first horizontal base frame 11, a second horizontal base frame 12 and a vertical frame 13. The first horizontal base frame 11 and the second horizontal base frame 12 are symmetrically fixed to the bottom of the vertical frame 13. The vertical frame 13 is supported by the first horizontal base frame 11 and the second horizontal base frame 12, so that the hanger 1 is placed stably.

[0030] like Figure 1 and Figure 3 As shown, a first support rod 5 is fixedly provided between the first horizontal base frame 11 and the vertical frame 13, and a second support rod 6 is fixedly provided between the second horizontal base frame 12 and the vertical frame 13. The first support rod 5 strengthens the connection between the first horizontal base frame 11 and the vertical frame 13, and the second support rod 6 strengthens the connection between the second horizontal base frame 12 and the vertical frame 13.

[0031] like Figure 1 As shown, there are two first support rods 5 and two second support rods 6, and the two first support rods 5 are symmetrically arranged, and the two second support rods 6 are symmetrically arranged, so that the connection between the first horizontal base frame 11 and the vertical frame 13, and the connection between the second horizontal base frame 12 and the vertical frame 13 is more stable, thereby enhancing the stability of the overall structure.

[0032] like Figure 3 As shown, a connecting ring 131 is fixedly provided in the upper middle position of the stand 13, and one end of the sling 2 is tied to the connecting ring 131. The connecting ring 131 prevents the sling 2 from sliding and moving after being bound. In the present embodiment, the sling 2 is a nylon rope, which has high strength and good fatigue resistance.

[0033] like Figure 2 As shown, the inner ring of the lifting ring 3 is provided with a rubber ring 31, and the rubber ring 31 prevents the pneumatic pick 4 from vibrating and colliding with the inner ring of the lifting ring 3 during operation and being damaged, thereby extending the service life of the pneumatic pick 4.

[0034] like Figure 1 and Figure 4 As shown, the head length of the pneumatic pick 4 is 1.5 meters to 2.5 meters, so that the cleaning range of the pneumatic pick 4 is deep enough to ensure effective unblocking. In this embodiment, the head length of the pneumatic pick 4 is 2 meters, and the pneumatic pick 4 adopts the G20 type. The user can select the appropriate head length and type of pneumatic pick 4 according to actual needs.

[0035] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
