Description

Technical Field

[0001] This utility model relates to the field of electric drum technology, and in particular to a high-power explosion-proof electric drum. Background Technology

[0002] High-power electric rollers, as an important type of mechatronics equipment, are widely used in belt conveyors in industries such as mining, building materials, and ports. The live parts of the equipment are placed in a specially designed housing to achieve explosion protection. This housing has the function of isolating the sparks and arcs generated by the electrical components inside the housing from the explosive mixture outside the housing.

[0003] A search revealed Chinese patent publication number CN220097578U, which discloses an oil-cooled electric roller for easy heat dissipation. This patent uses a heat-conducting ring to absorb the heat generated by the motor, thereby achieving continuous heat dissipation of the drive motor during operation through heat sinks. However, this device has some problems: the drum body is filled with oil that fills one-third of the drum's diameter. The rotation of the drum alone cannot splash the oil onto the drive motor, resulting in poor oil flow and affecting the heat dissipation effect. Utility Model Content

[0004] The purpose of this invention is to provide a high-power explosion-proof electric drum to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A high-power explosion-proof electric drum includes a fixed shaft, a connecting column fixedly connected to one side of the fixed shaft, a first end cover rotatably connected to the connecting column, a bearing installed between the first end cover and the connecting column, a first support fixedly fixed to the side of the connecting column away from the fixed shaft, a sleeve fixedly installed on the outside of the first end cover, and a motor fixedly installed on the side of the fixed shaft away from the connecting column.

[0007] A heat dissipation mechanism is provided inside the sleeve near the motor. The heat dissipation mechanism includes a fixed rod, which is fixedly installed on the upper end of the fixed shaft. An arc-shaped plate is fixedly installed on the upper end of the fixed rod. The arc-shaped plate is located on the side of the fixed rod near the motor and is a semi-circle with the opening facing downwards.

[0008] Two filter frames are fixedly installed on the inner wall of the sleeve. The two filter frames are symmetrical along the radial direction of the sleeve. Oil-absorbing cotton is provided inside the filter frames. The oil-absorbing cotton is made of polypropylene. The side of the filter frame closest to the motor is slidably connected to two symmetrical sliding rods. The side of the sliding rod closest to the arc plate is rotatably connected to a roller.

[0009] Preferably, a second end cap is fixedly installed on the side of the sleeve away from the first support, and a connecting shaft is rotatably connected to the side of the second end cap away from the fixed shaft. A bearing is installed between the connecting shaft and the second end cap, and a second support is fixedly connected to the connecting shaft.

[0010] Preferably, a drive wheel is fixedly installed on the output shaft of the motor, and a fixing bracket is fixedly installed on the side of the motor near the second end cover. The fixing bracket is U-shaped with its opening facing the motor, and symmetrical transmission bearings are fixedly installed on both sides at the upper end of the fixing bracket.

[0011] Preferably, a transmission bearing is rotatably connected to a transmission column, and a driven gear is fixedly connected to the side of the transmission column near the motor. The driven gear meshes with a driving wheel, and a transmission wheel is fixedly connected to the transmission column. The transmission wheel is located between symmetrical transmission bearings.

[0012] Preferably, a symmetrical mounting base is fixedly connected to the side of the second end cover near the motor.

[0014] The beneficial effects are as follows: when the sleeve drives the filter frame to rotate to the lower end of the sleeve, the oil-absorbing cotton inside the filter frame absorbs a sufficient amount of oil. Then the filter frame rotates to be close to the arc plate, and the arc plate and the roller roll together, causing the sliding rod to squeeze the oil-absorbing cotton. The oil flows out from the filter frame and is guided to the motor through the arc plate, which enhances the fluidity of the oil and thus enhances the cooling effect.

[0022] See Figure 1-5 A high-power explosion-proof electric drum includes a fixed shaft 101, a connecting column 102 fixedly connected to one side of the fixed shaft 101, a first end cover 103 rotatably connected to the connecting column 102, a bearing installed between the first end cover 103 and the connecting column 102, a first support 104 fixedly fixed to the side of the connecting column 102 away from the fixed shaft 101, a sleeve 201 fixedly installed on the outside of the first end cover 103, and a motor 501 fixedly installed on the side of the fixed shaft 101 away from the connecting column 102.

[0023] A heat dissipation mechanism is provided inside the sleeve 201 near the motor 501. The heat dissipation mechanism includes a fixed rod 401, which is fixedly installed on the upper end of the fixed shaft 101. An arc-shaped plate 402 is fixedly installed on the upper end of the fixed rod 401. The arc-shaped plate 402 is located on the side of the fixed rod 401 near the motor 501 and is a semi-circle with the opening facing downward.

[0024] Two filter frames 403 are fixedly installed on the inner wall of the sleeve 201. The two filter frames 403 are symmetrical about the radial direction of the sleeve 201. Oil-absorbing cotton made of polypropylene is provided inside the filter frames 403. The side of the filter frame 403 closest to the motor 501 is slidably connected to two symmetrical sliding rods 404. The side of the sliding rod 404 closest to the arc plate 402 is rotatably connected to a roller 405. When the sleeve 201 rotates, it drives the filter frames 403 to rotate around the motor 501. When the filter frames 403 rotate to the position of the sleeve 201, the filter frames 403 rotate around the motor 501. At the lower end of step 01, the oil-absorbing cotton inside the filter frame 403 absorbs a sufficient amount of oil. Then, the filter frame 403 rotates with the sleeve 201 to approach the arc plate 402. The arc plate 402 and the roller 405 roll together, causing the sliding rod 404 to squeeze the oil-absorbing cotton. The oil flows out from the filter frame 403 onto the arc plate 402 and is guided to the motor 501 through the arc plate 402. As the sleeve 201 rotates, the oil is continuously poured onto the motor 501, enhancing the fluidity of the oil and thus enhancing the cooling effect.

[0025] A second end cap 202 is fixedly installed on the side of the sleeve 201 away from the first support 104. A connecting shaft 301 is rotatably connected to the side of the second end cap 202 away from the fixed shaft 101. A bearing is installed between the connecting shaft 301 and the second end cap 202. The second support 302 is fixedly connected to the connecting shaft 301. In use, the first support 104 and the second support 302 are fixed to the frame with bolts.

[0026] A drive wheel 502 is fixedly installed on the output shaft of the motor 501. A fixing frame 601 is fixedly installed on the side of the motor 501 near the second end cover 202. The fixing frame 601 is U-shaped with its opening facing the motor 501. A transmission bearing 602 with two symmetrical sides is fixedly installed on the upper end of the fixing frame 601. The motor 501 is started to drive the drive wheel 502 to rotate.

[0027] A transmission bearing 602 is rotatably connected to a transmission column 603. A driven gear 701 is fixedly connected to the side of the transmission column 603 closest to the motor 501. The driven gear 701 meshes with the driving gear 502. A transmission gear 702 is fixedly connected to the transmission column 603. The transmission gear 702 is located between symmetrical transmission bearings 602. The driving gear 502 meshes with the driven gear 701, causing the driven gear 701 to rotate. This causes the driven gear 701 to drive the transmission gear 702 to rotate through the transmission column 603.

[0028] A symmetrical mounting base 801 is fixedly connected to the side of the second end cover 202 near the motor 501. A fixing ring 802 is fixedly installed on the side of the mounting base 801 near the motor 501. An internal gear ring 703 is fixedly installed on the inner side of the fixing ring 802. The internal gear ring 703 meshes with the transmission wheel 702. The transmission wheel 702 meshes with the internal gear ring 703, causing the internal gear ring 703 to rotate. This causes the internal gear ring 703 to drive the second end cover 202 to rotate through the fixing ring 802, thereby causing the second end cover 202 to drive the sleeve 201 to rotate.

[0029] A junction box is fixedly installed on the side of the connecting column 102 away from the fixed shaft 101. An oil filling pipe 901 is fixedly connected to the side of the sleeve 201 near the junction box. An oil filling plug is threaded onto the oil filling pipe 901. An oil drain hole 902 is opened on the side of the sleeve 201 away from the connecting column 102. An oil drain plug is threaded onto the oil drain hole 902. After a period of use, the oil filling plug is rotated to add oil to the sleeve 201 through the oil filling pipe 901. Then the oil filling plug is tightened.

[0030] Working principle: During use, the first support 104 and the second support 302 are fixed to the frame with bolts. The motor 501 is started, driving the drive wheel 502 to rotate. The drive wheel 502 meshes with the driven gear 701, causing the driven gear 701 to rotate. The driven gear 701, through the transmission column 603, drives the transmission wheel 702 to rotate. The transmission wheel 702 meshes with the internal gear ring 703, causing the internal gear ring 703 to rotate. The internal gear ring 703, through the fixing ring 802, drives the second end cover 202 to rotate, thereby causing the second end cover 202 to drive the sleeve 201 to rotate. The motor 501 generates heat during operation. When the sleeve 201 rotates, it drives the filter frame 403 to rotate around the motor 501. 1. When the filter frame 403 rotates to the lower end of the sleeve 201, the oil-absorbing cotton inside the filter frame 403 absorbs a sufficient amount of oil. Then, the filter frame 403 rotates with the sleeve 201 to be close to the arc plate 402. The arc plate 402 and the roller 405 roll, causing the sliding rod 404 to squeeze the oil-absorbing cotton. The oil flows out from the filter frame 403 onto the arc plate 402 and is guided to the motor 501 through the arc plate 402. As the sleeve 201 rotates, the oil is continuously poured onto the motor 501, which enhances the fluidity of the oil and thus enhances the cooling effect. After a period of use, the oil filler plug is rotated to add oil into the sleeve 201 through the oil filler pipe 901, and then the oil filler plug is tightened.
