Description

Technical Field

[0002] Magnetic direct-drive drum motors can be used as mine hoists in mining. They play an important role in the mining process, mainly responsible for lifting miners and equipment from underground to the ground. However, since the load of mine hoists is often uneven, strong vibrations will occur, which will not only affect the service life of the hoist, but may also pose a threat to the safety of miners and equipment. Therefore, it is necessary to design a shock absorbing device suitable for mine hoists with uneven loads to reduce the vibration of the hoist, improve the safety of the hoisting process and the durability of the equipment.

[0003] In addition, under heavy load conditions, the coils on the stator inside the permanent magnet direct-drive drum motor will accumulate heat. Long-term heat accumulation will cause the permanent magnets fixed inside the drum rotor to demagnetize, reducing the service life of the motor. Therefore, it is necessary to design a permanent magnet direct-drive drum motor with good heat dissipation effect.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0033] Example 1

[0034] Reference Figure 1 to Figure 7The present embodiment provides a low-noise built-in drum motor, including a support seat 100 and a motor body 200, a support seat 100 is mounted with a stand 101, both ends of the motor body 200 are connected to the stand 101 through bearings, and a hydraulic damper 300 is connected to the stand 101 and the support seat 100; a heat sink 400 is arranged on the side of the motor body 200, and heat dissipation holes 201 and replacement holes 202 are alternately arranged on the side of the motor body 200, the heat sink 400 includes a cover 401 detachably arranged at the heat dissipation hole 201 and a fan 402 arranged in the cover 401, and a sealing plate 500 is arranged in the replacement hole 202.

[0035] The stand 101 provides support for the motor body 200 .

[0036] The motor body 200 is a drum motor.

[0037] In this embodiment, since the operating environment of the drum motor contains a lot of dust, it is particularly important to prevent dust from entering the motor and to clean the motor while using the fan to dissipate heat. Therefore, a filter plate 600 is provided at the heat sink to block the dust. When the dust accumulates to a certain extent and is difficult to clean, the best way is to replace it. However, the existing technology requires the disassembly of the heat sink, which causes the equipment to be shut down for maintenance, affecting the construction efficiency.

[0038] A cooling fan is installed at the heat dissipation hole 201 to perform heat dissipation work, and the replacement hole 202 is used to assist in replacing the filter plate 600. Furthermore, the heat dissipation element 400 is detachable, and a proper amount of heat dissipation element 400 can also be installed at the replacement hole 202 to further improve the heat dissipation efficiency when necessary.

[0039] The hydraulic damper 300 is used for shock absorption and noise reduction caused by vibration. Furthermore, a vibration sensor is provided on the equipment to detect the vibration of the equipment and feed back the information to the hydraulic damper 300 for real-time adjustment. This is a prior art and will not be described in detail.

[0040] An annular groove 203 is provided at the inner end of the motor body 200, and a carrier plate 204 is embedded in the annular groove 203. An arc groove 205 is provided on the side wall of the motor body 200 and communicates with the annular groove 203. A paddle plate 204a is provided on the side of the carrier plate 204, and the paddle plate 204a is arranged in the arc groove 205; a first magnetic surface 205a and a second magnetic surface 205b are respectively provided at both ends of the arc groove 205, and the paddle plate 204a and the first magnetic surface 205a and the second magnetic surface 205b can be magnetically attracted.

[0041] The carrier plate 204 can be rotated in the annular groove 203 by toggling the dial plate 204a. Specifically, the carrier plate 204 is fixed with two positions and is switched at these two positions. Specifically, the first position is that the dial plate 204a corresponds to the first magnetic surface 205a. At this time, the first hole 204b is correspondingly placed at the heat dissipation hole 201. The second position is that the dial plate 204a is toggled to correspond to the second magnetic surface 205b. At this time, the first hole 204b is moved to the corresponding replacement hole 202, and the filter plate 600 in the first hole 204b is replaced at the replacement hole 202.

[0042] The carrier plate 204 is alternately provided with first holes 204b and second holes 204c. The first hole 204b is provided with a first side arc groove 204d on its circumferential side, and the second hole 204c is provided with a second side arc groove 204e on its circumferential side.

[0043] It should be noted that a plurality of first holes 204b and second holes 204c are arranged in a circular array on the carrier plate 204, and the first holes 204b and the second holes 204c have the same structure, but the opening positions of the first side arc groove 204d and the second side arc groove 204e are different, so that when the first hole 204b and the first side arc groove 204d are rotated to make the first hole 204b and the second hole 204c overlap, there is an angular deviation between the first side arc groove 204d and the second side arc groove 204e.

[0044] A filter plate 600 is disposed in each of the first hole 204b and the second hole 204c. A first side block 601 and a second side block 602 are disposed on the side of the filter plate 600. A first sliding shaft 603 is disposed on the first side block 601, and a second sliding shaft 604 is disposed on the second side block 602.

[0045] The first side block 601 and the second side block 602 are symmetrically arranged at two ends of the filter screen plate 600 .

[0046] It should be noted that the first slide shaft 603 and the second slide shaft 604 are not installed on the filter plate arranged in the second hole 204c, because when the filter plate 600 in the first hole 204b is replaced, the second hole 204c is rotated to correspond to the heat dissipation hole 201, acting as a temporary filtering component, and its structural state does not need to change.

[0047] A first deflection groove 206 and a second deflection groove 207 are provided on the inner side of the end surface of the motor body 200 . The first sliding shafts 603 of two adjacent filter screens 600 are embedded in the first deflection groove 206 , and the second sliding shafts 604 of two adjacent filter screens 600 are embedded in the second deflection groove 207 .

[0048] The side wall of the replacement hole 202 is provided with a first square groove 202a and a second square groove 202b. The first deflected groove 206 connects the first square groove 202a with one side of the heat dissipation hole 201 , and the second deflected groove 207 connects the second square groove 202b with the other side of the heat dissipation hole 201 .

[0049] A first block 501 and a second block 502 are arranged on the side of the sealing plate 500. The first block 501 is embedded in the first square groove 202a, and the second block 502 is embedded in the second square groove 202b. A first transition groove 503 and a second transition groove 504 are arranged on the sealing plate 500. The first transition groove 503 is a part of the first bias groove 206, and the second transition groove 504 is a part of the second bias groove 207.

[0050] It should be noted that the sealing plate 500 is arranged in the replacement hole 202 in a magnetic manner. Specifically, the circumferential side surface of the sealing plate 500 and the side surface of the replacement hole are provided with annular magnetic strips that attract each other.

[0051] The distance between the first endpoint A1 of the first slant groove 206 and the center O is smaller than the distance between the second endpoint A2 of the first slant groove 206 and the center O. The distance between the third endpoint B1 of the second slant groove 207 and the center O is smaller than the distance between the fourth endpoint B2 of the second slant groove 207 and the center O.

[0052] For the convenience of design, in the initial state, the line connecting the first side block 601 and the second side block 602 of the filter screen plate 600 corresponding to the replacement hole 202 passes through the center O, so Figure 7 In the structure shown, when the carrier plate 204 is rotated from right to left, the filter screen plate 600 on the right side will move and deflect along the second deflection groove 207 and the first deflection groove 206, and the state on the right side of the figure will be changed to the state on the left side of the figure. It should be noted that in the initial state Figure 7 The filter screen plate 600 on the right corresponds to the state where it is set at the replacement hole 202. Figure 7 The filter plate 600 on the left corresponds to the state where it is arranged at the heat dissipation hole 201 .

[0053] In the present invention, the replacement process of the filter screen plate 600 is to take out the sealing plate 500 in the replacement hole 202, and take out the filter screen plate 600 corresponding to the replacement hole 202. Preferably, the first transition groove 503 and the second transition groove 50 on the sealing plate 500 are provided with magnetic surfaces, and the first sliding shaft 603 and the second sliding shaft 604 are magnetic materials. Therefore, when the sealing plate 500 is removed, the filter screen plate 600 is also driven to be removed, or the filter screen plate 600 is not initially placed at the corresponding position of the replacement hole 202, and the sealing plate 500 is covered to prevent dust from being blown out.

[0054] Then, the dial plate 204a is toggled to rotate the filter plate 600 at the heat dissipation hole 201 to the replacement hole 202. At the same time, the filter plate 600 is deflected under the restriction of the second bias groove 207 and the first bias groove 206. The first block 501 and the second block 502 correspond to the first square groove 202a and the second square groove 202b, so that the filter plate 600 can be taken out. Then, the filter plate 600 is taken out, and a new one is placed at the replacement hole 202. The dial plate 204a is returned, and the filter plate 600 moves back to the heat dissipation hole 201 and is deflected and fixed.

[0055] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
