Description

Technical Field

[0001] The utility model relates to the technical field of dust prevention of coal piles, in particular to a coal pile protection device in a coal yard. Background Art

[0002] A coal yard is an area where humans mine coal resources in coal-rich mining areas. During mining, the coal will be piled in the coal yard, and the coal pile will generate a lot of dust under the action of wind. This dust not only blocks the line of sight, but also causes the loss of coal powder. Therefore, it is necessary to use fog cannons to prevent dust.

[0003] At present, after the existing fog cannon completes the work of spraying and dust prevention, the openings at both ends of the fog cannon barrel are still in an open state. Due to the complex internal environment of the coal mine, dust and debris will enter the fog cannon barrel and adhere to the fan and other components inside the fog cannon barrel, which will affect the normal use of the fog cannon in the later stage. For this reason, we propose a coal yard coal pile protection device to solve the above problems. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4A coal pile protection device for a coal yard includes a machine base 1, a fog cannon barrel 2 is installed on the top of the machine base 1, the atomization dust prevention principle of the machine base 1 and the fog cannon barrel 2 is the existing technology, and the angle of the fog cannon barrel 2 can be adjusted by remote control. The specific working principle is not described in detail here. Support frames 3 are symmetrically connected to both sides of the machine base 1, and rotating rods 4 are inserted at the tops of the supporting frames 3. Rotating blocks 5 are distributed on the sides of the rotating rods 4 close to each other, and the sides of the rotating blocks 5 are connected to covering plates 6, and the sides of the covering plates 6 are glued with rubber plates 12, through the rubber plates 1 The setting of 2 can ensure the sealing of the two groups of covering plates 6 when covering the opening of the fog cannon barrel 2. The side of the rotating rod 4 away from each other is connected with a rotating block 7, and two groups of insertion grooves are opened inside the rotating block 7, and insertion rods 8 are inserted inside the two groups of insertion grooves. The insertion rods 8 are connected to the side away from the support frame 3 through a pulling bar 9, and a positioning groove compatible with the insertion rod 8 is opened inside the support frame 3. Four groups of positioning grooves are opened inside the support frame 3, so that the two groups of insertion rods 8 rotated 180 degrees can be limited and fixed.

[0023] Further, see Figure 2 and Figure 3 It can be known that a card block 13 is inserted into the inner side of the support frame 3, and a brush 14 is connected to the side of the card block 13. When the outer wall of the cover plate 6 needs to be cleaned, the staff can first pull the pulling bar 9 to remove the two sets of inserted rods 8 from the positioning grooves of the support frame 3, and then the staff can rotate the rotating block 7 to make the cover plate 6 rotate and abut against the brush 14, so as to achieve rapid cleaning of the dust on the outer wall of the cover plate 6.

[0024] Further, see Figure 4 It can be known that a spring 10 is symmetrically connected to the inner side of the pull bar 9, and the other end of the spring 10 is connected to the rotating block 7. Through the connection of the spring 10, the tightness of the insertion rod 8 when inserted into the positioning groove inside the support frame 3 can be ensured.

[0025] Further, see Figure 4 It can be seen that the sides of the rotating block 7 are equidistantly connected with connecting rods, and the other end of the connecting rods is connected with connecting balls. Through the mutual cooperation of the connecting rods and the connecting balls, the rotating block 7 can be rotated more conveniently after the two sets of inserted rods 8 are pulled out of the positioning grooves.

[0026] Further, see Figure 4 It can be known that a connecting ring is sleeved on the outer side of the rotating rod 4, and a groove hole matched with the connecting ring is opened inside the supporting frame 3. The connecting ring sleeved on the outer side of the rotating rod 4 cooperates with the groove hole opened inside the supporting frame 3 to effectively ensure the stability of the rotating rod 4 during rotation.

[0027] Further, see Figure 4It can be known that the end of the rotating rod 4 away from the rotating block 7 is connected to the mounting plate 11, and the other end of the mounting plate 11 is connected to the rotating block 5 by bolts. Through the cooperation between the bolts and the mounting plate 11, it is convenient for the staff to separate the damaged covering plate 6 from the rotating rod 4 in time.

[0028] Further, see Figure 2 and Figure 3 It can be known that the block 13 is configured as a U-shaped structure, and the front of the block 13 is connected to the side wall of the support frame 3 by bolts. Since the block 13 is configured as a U-shape, when the brush 14 reaches the end of its service life, the staff can pull out the bolts from the block 13 and the inside of the support frame 3, and then push the block 13 to remove it from the inner side of the support frame 3 for replacement.

[0029] Working principle: When the utility model is in use, the staff can first push the machine base 1 to a suitable area of ​​the coal mine, and then start the machine base 1, so that the atomized water is sprayed from the nozzle of the fog cannon barrel 2 to achieve the purpose of dust prevention. When the fog cannon barrel 2 completes the spraying, the staff can remotely control the rotation of the fog cannon barrel 2 and rotate its angle to be level with the machine base 1. Then the staff can pull the pulling bar 9 in turn, so that the two groups of inserted rods 8 connected to the inner side thereof are forced to be pulled out from the inside of the support frame 3, and then the staff can rotate the rotating block 7, thereby driving the rotating rod 4 to rotate at the same time, so that the rotating rod 4 inside The side-distributed rotating block 5 and covering plate 6 are rotated under force. When the rotating block 7 is rotated one hundred and eighty degrees, the covering plate 6 is able to cover the opening of the fog cannon barrel 2, and then the staff can stop pulling the pulling bar 9, so that the two groups of inserted rods 8 are embedded in the other two groups of positioning grooves inside the support frame 3, so as to realize the limiting work of the rotating block 7, thereby realizing the fixing of the position of the covering plate 6, and then the staff can pull another group of pulling bars 9 and rotate another group of rotating blocks 7, so as to realize the covering of the opening on the other side of the fog cannon barrel 2. The above is the entire working principle of the utility model.
