Description

Technical Field

[0001] The utility model relates to the technical field of electromechanical equipment for coal mines, and more specifically to electromechanical equipment for coal mines used for coal mining. Background Art

[0002] Coal mining refers to the process of extracting coal resources from underground or on the surface through mining technology and equipment. Coal mining usually includes exploration, development, excavation and transportation. In the process of coal mining, various equipment and technologies are needed to mine coal resources. A lot of dust will be generated in the process of coal mining, so dust removal fans are usually required.

[0003] At present, during the use of dust removal fans in the prior art, since some of the existing dust removal fans are not easy to disassemble, a large amount of dust will be inhaled during use. As time goes by, some dust may adhere to the protective cover and the induced draft fan of the equipment, resulting in a decrease in the air intake of the equipment. At the same time, the heat dissipation performance of the fan will be affected, and the fan may be reduced in performance or damaged due to overheating, thereby affecting the dust removal effect; and when cleaning or replacing the filter inside the existing equipment, workers usually need to use tools to remove the back panel of the equipment, and then take out the filter for cleaning or replacement. Since the mine is generally dark, it is difficult for workers to operate, resulting in a relatively time-consuming and labor-intensive process. Therefore, there is an urgent need for a coal mine electromechanical equipment used for coal mining to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a coal mine electromechanical equipment for coal mining to solve the problems existing in the above-mentioned background technology.

[0005] The utility model provides the following technical solution: a coal mine electromechanical equipment for coal mining, comprising:

[0006] The main structure includes an outer frame and a hinge rod, and the upper and lower ends of the hinge rod are inserted into the interior of one end of the outer frame, an induced draft fan is installed on the upper surface of the inner part of the outer frame, and a filter screen is arranged inside one side of the outer frame;

[0007] An opening and closing structure, the opening and closing structure includes a hinge column, and the hinge column is sleeved on the outer surface of the hinge rod, and the opening and closing structure is used for opening and closing the device;

[0008] The clamping structure includes a fixing plate, and the surface of one side of the fixing plate is fixedly connected to the outer surface of one side of the outer frame, and the clamping structure is used for clamping the filter screen.

[0009] Preferably, the main structure also includes a card slot, a card slot is opened inside one side of the inner part of the outer frame, and a supporting plate is fixedly connected to the inner surface of the lower end of the outer frame, and there are two groups of supporting plates, and dust drawers are arranged on the upper surfaces of the two groups of supporting plates, a threaded plate is fixedly connected to the surface of one end of the lower end of one side of the outer frame, and the internal thread of the threaded plate is connected to a limiting screw, and a back plate is fixedly connected to the inside of the other end of the outer frame.

[0010] Preferably, a dust collecting groove is provided on the lower surface inside the outer frame, a blocking block is provided at one end of the limiting screw, and the blocking block is attached to the outer surface of one end of the dust collecting drawer.

[0011] Preferably, the opening and closing structure also includes a protective cover, and one end of one side surface of the protective cover is fixedly connected to one end surface of the hinge column, and the interior of one end of the protective cover is fixedly connected to a fixed seat, a pull rod is inserted into the interior of one side of the fixed seat, and one end of the pull rod is fixedly connected to a stop block, and one end of the stop block is fixedly connected to a locking plate, one end of the locking plate is inserted into the interior of the other side of the fixed seat, and one end of the interior of the fixed seat is fixedly connected to a return spring.

[0012] Preferably, one end of the return spring abuts against the surface of one side of the abutment block, and the size and position of one end of the locking plate are matched with the size and position of the locking slot.

[0013] Preferably, the snap-fit ​​structure also includes a resist column, and the surface of one end of the resist column is fixedly connected to the inner surface of the other side of the fixed plate, and the internal bearing on the other side of the fixed plate is connected to a sleeve, the interior of the sleeve is fixedly connected to a limiting column, and a snap-fit ​​block is fixedly connected to the outer surface of the sleeve, the resist column is a quarter-cylindrical shape, and the limiting column is a half-cylindrical shape, and the radius size of the internal space of the sleeve is the same as the radius size of the resist column and the limiting column, and the surface of one end of the snap-fit ​​block is attached to the outer surface of one end of the filter.

[0014] The technical effects and advantages of the utility model are as follows: the utility model drives the stop block and the locking plate to move synchronously by pulling the pull rod. At this time, one end of the locking plate leaves the interior of the slot and pulls the fixing seat outward, so that the hinge column rotates on the outer surface of the hinge rod. At this time, the dust on the surface of the induced draft fan and the protective cover inside the main structure can be cleaned, ensuring the air intake of the equipment and the heat dissipation of the induced draft fan, avoiding performance reduction or damage of the induced draft fan, and making the dust removal effect of the equipment more stable.

[0015] The sleeve is rotated inside the fixed plate to make the locking block rotate synchronously. At the same time, due to the presence of the resisting column and the limiting column, the sleeve and the locking block can only rotate ninety degrees. At this time, the surface of one end of the locking block and the surface of one end of the filter are no longer engaged. The filter can be directly pulled out from the inside of the main structure for cleaning or replacement, which saves the process of workers disassembling the equipment with the help of tools. It is also easy to operate in darker mines, which to a certain extent saves time and effort in the whole process. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The opening and closing structure 4 also includes a protective cover 42, and one end of the surface of one side of the protective cover 42 is fixedly connected to the surface of one end of the hinge column 41, and the interior of one end of the protective cover 42 is fixedly connected to a fixing seat 43, a pull rod 44 is inserted into the interior of one side of the fixing seat 43, and one end of the pull rod 44 is fixedly connected to a stop block 45, and one end of the stop block 45 is fixedly connected to a clamping plate 46, one end of the clamping plate 46 is inserted into the interior of the other side of the fixing seat 43, and one end of the interior of the fixing seat 43 is fixedly connected to a return spring 47, one end of the return spring 47 is against the surface of one side of the stop block 45, and the size and position of one end of the clamping plate 46 are adapted to the size and position of the slot 13. Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the hinge column 41 can be sleeved on the outer surface of the hinge rod 12 and hingedly rotated, and the locking plate 46 can be inserted into the interior of the slot 13 to close the device. When the pull rod 44 is pulled, the stop block 45 can be driven to move synchronously with the locking plate 46, so that one end of the locking plate 46 is disengaged from the interior of the slot 13 and the fixing seat 43 is pulled outward to open the device. The dust on the surface of the protective cover 42 and the induced draft fan 2 can be cleaned, and the stop block 45 can push the reset spring 47 to shrink it when moving, and the synchronous reset spring 47 can push the locking plate 46 to reset by its own elastic force, so that the device has the function of quick opening and closing.

[0033] The clamping structure 5 also includes a stopper column 52, and the surface of one end of the stopper column 52 is fixedly connected to the inner surface of the other side of the fixing plate 51, and the inner bearing of the other side of the fixing plate 51 is connected to a sleeve 53, the inner part of the sleeve 53 is fixedly connected to a limiting column 54, and a clamping block 55 is fixedly connected to the outer surface of the sleeve 53, the stopper column 52 is a quarter cylinder, and the limiting column 54 is a half cylinder, and the radius size of the inner space of the sleeve 53 is the same as the radius size of the stopper column 52 and the limiting column 54, and the surface of one end of the clamping block 55 is attached to the outer surface of one end of the filter screen 3, according to Figure 8 and Fig. 9 As shown, when the limiting column 54 rotates ninety degrees, one side surface will fit with one side surface of the resisting column 52, so that the engaging block 55 is perpendicular to the ground and in a vertical state. When the limiting column 54 fits with the upper end surface of the resisting column 52, the engaging block 55 engages with the filter screen 3 parallel to the ground. This design allows the sleeve 53, the limiting column 54 and the engaging block 55 to only rotate ninety degrees inside the fixed plate 51, so that the engaging state of the engaging structure 5 on the filter screen 3 can be quickly switched and is not affected by the angle, which is convenient for operation in darker mines.

[0034] Working principle: when the equipment is in use, the equipment is placed at a suitable location through the outer frame 11, and the induced draft fan 2 is powered by an external power supply. The induced draft fan 2 is started to absorb the dust generated during coal mining, and the dust is sucked into the interior of the main structure 1, and the dust is filtered through the filter 3. The filtered gas is discharged from the interior of the equipment through the back plate 18, and a part of the dust falls into the interior of the dust drawer 15 through the dust collecting groove on the lower surface of the inner part of the outer frame 11. When there is a lot of dust in the dust drawer 15, the limiting screw 17 is rotated inside the threaded plate 16, so that the blocking block set at one end of the limiting screw 17 is no longer in contact with the outer surface of one end of the dust drawer 15, and the dust drawer 15 is pulled outward to dump the dust inside;

[0035] After the equipment has been used for a period of time, some dust will accumulate on the surface of the induced draft fan 2 and the protective cover 42. At this time, the pull rod 44 is pulled to drive the stop block 45 and the locking plate 46 to move synchronously. At the same time, the stop block 45 pushes the reset spring 47 to shrink. At this time, one end of the locking plate 46 is separated from the inside of the slot 13, and then the fixing seat 43 is pulled outward, so that the protective cover 42 is sleeved on the outer surface of the hinge rod 12 and hingedly rotated. At this time, the equipment is in an open and closed state, and then the dust on the surface of the induced draft fan 2 and the protective cover 42 is cleaned. After the cleaning is completed, the pull rod 44 is pulled, and the protective cover 42 is rotated to align the locking plate 46 with the slot 13, and then the pull rod 44 is released. The reset spring 47 resets and pushes the locking plate 46 due to its own elastic force. At this time, one end of the locking plate 46 is inserted into the inside of the slot 13, and the equipment is in a closed state.

[0036] When the filter 3 needs to be cleaned or replaced, the sleeve 53 is rotated 90 degrees inside the other side of the fixing plate 51 to drive the limiting column 54 and the locking block 55 to rotate synchronously. The surface of one end of the locking block 55 is no longer locked with the surface of one end of the filter 3. The filter 3 is pulled out from the inside of one side of the main structure 1 for cleaning or replacement. After completion, the filter 3 is pushed into the inside of one side of the main structure 1, and the sleeve 53 and the locking block 55 are rotated 90 degrees so that the surface of one end of the locking block 55 is re-engaged with the surface of one end of the filter 3 to fix the filter 3 inside the main structure 1. The above is the entire working principle of the present invention.
